Placenta fails to deliver even after 30 minutes of delivery.


Approach to Retained Placenta


Empty the bladder by inserting a Foley’s catheter. A full bladder may obstruct placental expulsion.
Watch for signs of placental separation:
Suprapubic bulge
Permanent cord lengthening
Gush of blood
Feel of placenta in vagina

I. If signs of placental separation present:
Placenta has separated but is trapped inside the uterus
Causes:
Poor voluntary expulsive efforts
Can occur due to maternal exhaustion, deep anesthesia (epidural/spinal)
Treat based on uterine tone:
Uterus relaxed: Oxytocin and Controlled Cord Traction (CCT)

Uterus contracted: Manual Removal of Placenta under anesthesia

Constriction ring 
Hourglass/localized contraction of circular muscles of the uterus
This obstructs the delivery of placenta
Treatment: Manual Removal of Placenta under anesthesia. Oxytocin has no role in this case. 

Note: 
At any point of time while doing CCT, if cord breaks, next step is Manual Removal of Placenta (NEET PG 2022)

II. If signs of placental separation absent:
Placenta has not separated, and is adhered to the uterus
Causes:
Simple adherence
Myometrium not invaded. 
Risk factors: preterm labor, grand multiparity, uterine overdistension
Management: Manual Removal of Placenta under anesthesia

Morbid adherence (Placenta accreta spectrum)
Myometrium is invaded. 
Risk factors: Previous cesarean, uterine surgery
Note: If Morbidly adherent placenta is already diagnosed by Ultrasound in antenatal period, we plan for a caesarean section followed by hysterectomy if failure to separate 

Complications
Postpartum hemorrhage (PPH), leading to shock
Uterine inversion
Puerperal sepsis
Future recurrence in subsequent pregnancies</video:title><video:description>AI-generated educational video covering teach this Retained Placenta

Placenta fails to deliver even after 30 minutes of delivery.


Approach to Retained Placenta


Empty the bladder by inserting a Foley’s catheter. A full bladder may obstruct placental expulsion.
Watch for signs of placental separation:
Suprapubic bulge
Permanent cord lengthening
Gush of blood
Feel of placenta in vagina

I. If signs of placental separation present:
Placenta has separated but is trapped inside the uterus
Causes:
Poor voluntary expulsive efforts
Can occur due to maternal exhaustion, deep anesthesia (epidural/spinal)
Treat based on uterine tone:

Ex Q. 3 (1) Why does the energy of electron increase as we move from first shell to second shell? 09202057

Ans. The energy of an electron increases as we move from the first to the second shell because the second shell is farther away from the nucleus which means that electron in the second shell has high energy as compared to the electron in the first shell. This increase in distance from the nucleus results in a higher energy level for electron in outer shell.</video:title><video:description>AI-generated educational video covering Q.1.

Options are contracts within the derivatives market, which give the right, but not the obligation, to buy or sell an underlying security at a specific strike price. Since it&amp;apos;s a right and not an obligation, the option holder doesn&amp;apos;t have to buy or sell the stock when it expires. The amount paid to have this option is called the option premium, which can be simply understood as the price of the option.

Options are good indicators of market participants&amp;apos; psychology and can be useful in exploring Alpha signals. Let&amp;apos;s learn some basic knowledge needed to use option data for Alpha exploration.

📑 Two Types of Options
As mentioned above, there are two categories of options: the right to buy and the right to sell. The right to buy is called a Call Option, and the right to sell is called a Put Option.

Call Option

A Call Option is the right to buy an asset at a predetermined price.
For example, if Company A&amp;apos;s stock is currently $60 and you want to buy it at the same price a week later, you can pay the option premium and buy a $60 call option expiring next week. If Company A&amp;apos;s stock price rises to $70 at expiration, you can buy the stock with a $10 profit, right? In this case, as expiration approaches, the call option&amp;apos;s price itself will rise significantly, resulting in profit.
Therefore, buying call options can bet on asset price increases (long position).

Put Option

A Put Option is the right to sell an asset at a predetermined price.
Think of put options as the opposite of call options - buying put options can bet on asset price decreases (short position).

🔍 Key Terms
Strike Price: The price agreed to buy or sell in the future
Breakeven Price: The point where neither profit nor loss occurs
Expiration: The last date to exercise the right
Premium: The price of the option
Volatility: Indicator of stock price volatility
Historical Volatility: Actual past price volatility
Implied Volatility: Expected future volatility derived from option prices
📏 Volatility in Options
Volatility affects option prices. Higher stock price volatility increases demand for options to hedge risks or bet on price movements, leading to higher option prices. Volatility can be divided into Historical Volatility and Implied Volatility.

Historical Volatility is a lagging indicator calculated from past actual price data, typically by annualizing the standard deviation of daily returns.
Implied Volatility is a leading indicator derived from current market option prices using models like Black-Scholes, reflecting market participants&amp;apos; future expectations. Since it&amp;apos;s calculated from option prices, it can also be considered another indicator of option prices.
While Historical Volatility comes from existing stock prices, Implied Volatility is derived from option prices. Comparing these two volatilities can help evaluate whether options or stocks are overvalued/undervalued.</video:title><video:description>AI-generated educational video covering What are Options?

for example, if company a&amp;apos;s stock is currently $60 and you want to buy it at the same price a week later, you can pay the option premium and buy a $60 call option expiring next week. if company a&amp;apos;s stock price rises to $70 at expiration, you can buy the stock with a $10 profit, right? in this case, as expiration approaches, the call option&amp;apos;s price itself will rise significantly, resulting in profit.
therefore, buying call options can bet on asset price increases (long position).

put option

a put option is the right to sell an asset at a predetermined price.
think of put options as the opposite of call options - buying put options can bet on asset price decreases (short position).

🔍 key terms
strike price: the price agreed to buy or sell in the future
breakeven price: the point where neither profit nor loss occurs
expiration: the last date to exercise the right
premium: the price of the option
volatility: indicator of stock price volatility
historical volatility: actual past price volatility
implied volatility: expected future volatility derived from option prices
📏 volatility in options
volatility affects option prices. higher stock price volatility increases demand for options to hedge risks or bet on price movements, leading to higher option prices. volatility can be divided into historical volatility and implied volatility.

historical volatility is a lagging indicator calculated from past actual price data, typically by annualizing the standard deviation of daily returns.
implied volatility is a leading indicator derived from current market option prices using models like black-scholes, reflecting market participants&amp;apos; future expectations. since it&amp;apos;s calculated from option prices, it can also be considered another indicator of option prices.
while historical volatility comes from existing stock prices, implied volatility is derived from option prices. comparing these two volatilities can help evaluate whether options or stocks are overvalued/undervalued.</video:tag><video:tag>level-2</video:tag><video:tag>educational</video:tag><video:category>Education</video:category></video:video></url><url><loc>https://magiacademy.com/video/bd9b917f-691e-4c63-a58c-602d0dc8d102</loc><lastmod>2026-03-26</lastmod><changefreq>weekly</changefreq><priority>0.8</priority><video:video><video:thumbnail_loc>https://storage.googleapis.com/magi-f7f13.firebasestorage.app/thumbnails/2026-03/explain_high_lows_and_midpoints_of_candles_and_why_price_behaves_the_way_it_bd9b917f.jpg</video:thumbnail_loc><video:title>Explain high, lows and midpoints of candles and why price behaves the way it does in accordance with time.

There are six types of neural networks that can be used.


Feedforward Networks: A feedforward neural network is a simple artificial neural network architecture in which data moves from input to output in a single direction.
Singlelayer Perceptron: A single-layer perceptron consists of only one layer of neurons . It takes inputs, applies weights, sums them up and uses an activation function to produce an output.
Multilayer Perceptron (MLP): MLP is a type of feedforward neural network with three or more layers, including an input layer, one or more hidden layers and an output layer. It uses nonlinear activation functions.
Convolutional Neural Network (CNN): A Convolutional Neural Network (CNN) is a specialized artificial neural network designed for image processing. It employs convolutional layers to automatically learn hierarchical features from input images, enabling effective image recognition and classification.
Recurrent Neural Network (RNN): An artificial neural network type intended for sequential data processing is called a Recurrent Neural Network (RNN). It is appropriate for applications where contextual dependencies are critical such as time series prediction and natural language processing, since it makes use of feedback loops which enable information to survive within the network.
Long Short-Term Memory (LSTM): LSTM is a type of RNN that is designed to overcome the vanishing gradient problem in training RNNs. It uses memory cells and gates to selectively read, write and erase information.</video:title><video:description>AI-generated educational video covering Types of Neural Networks

Let&amp;apos;s consider a record of an email dataset:



To classify this email, we will create a feature vector based on the analysis of keywords such as &amp;quot;free&amp;quot; &amp;quot;win&amp;quot; and &amp;quot;offer&amp;quot;

The feature vector of the record can be presented as:

&amp;quot;free&amp;quot;: Present (1)
&amp;quot;win&amp;quot;: Absent (0)
&amp;quot;offer&amp;quot;: Present (1)
How Neurons Process Data in a Neural Network
In a neural network, input data is passed through multiple layers, including one or more hidden layers. Each neuron in these hidden layers performs several operations, transforming the input into a usable output.

1. Input Layer: The input layer contains 3 nodes that indicates the presence of each keyword.

2. Hidden Layer: The input vector is passed through the hidden layer. Each neuron in the hidden layer performs two primary operations: a weighted sum followed by an activation function.

Weights:
Neuron H1: [0.5,−0.2,0.3]
Neuron H2: [0.4,0.1,−0.5]
Input Vector: [1,0,1]
Weighted Sum Calculation
For H1: (1×0.5)+(0×−0.2)+(1×0.3)=0.5+0+0.3=0.8
For H2: (1×0.4)+(0×0.1)+(1×−0.5)=0.4+0−0.5=−0.1
Activation Function
Here we will use ReLu activation function:

H1 Output: ReLU(0.8)= 0.8
H2 Output: ReLu(-0.1) = 0
3. Output Layer
The activated values from the hidden neurons are sent to the output neuron where they are again processed using a weighted sum and an activation function.

Output Weights: [0.7, 0.2]
Input from Hidden Layer: [0.8, 0]
Weighted Sum: (0.8×0.7)+(0×0.2)=0.56+0=0.56
Activation (Sigmoid):
4. Final Classification
The output value of approximately 0.636 indicates the probability of the email being spam.
Since this value is greater than 0.5, the neural network classifies the email as spam (1).</video:title><video:description>AI-generated educational video covering Example of Email Classification

storia nasce da un percorso lungo, non da un’intuizione improvvisa. Nasce dal lavoro quotidiano con l’industria, con impianti che producono valore reale e che vivono di continuità operativa, affidabilità e tempo. Per anni abbiamo costruito soluzioni di intelligenza artificiale applicata a contesti industriali complessi: energia, manifattura, manutenzione, infrastrutture critiche. In questo percorso abbiamo imparato che l’industria non chiede “AI”, chiede risultati: meno fermi, meno sprechi, più controllo, più prevedibilità.
All’inizio il focus era sull’asset: macchine, linee, impianti. Ogni asset come un sistema vivo, con il suo funzionamento, i suoi segnali, i suoi dati. Da qui nasce l’idea del gemello digitale come rappresentazione operativa dell’asset: non una copia statica, ma un modello vivo che raccoglie dati, li trasforma in KPI, allarmi, indicatori di salute, suggerimenti. Questo primo livello ha permesso di accumulare una conoscenza profonda del dominio industriale: capire come si comportano davvero gli impianti, quali segnali contano, quali pattern si ripetono, dove si genera valore e dove si perde tempo.
Con il tempo, però, emerge un limite strutturale. Anche quando i dati sono integrati e i modelli funzionano, l’intelligenza resta confinata in progetti specifici. Ogni nuova esigenza richiede un nuovo sviluppo, ogni estensione un nuovo sforzo, ogni soluzione vive separata dalle altre. L’AI funziona, ma non diventa mai una capacità continua dell’organizzazione. Questo non è un problema isolato: è la condizione in cui oggi si trova gran parte del mercato, dove l’adozione dell’AI cresce più velocemente della sua capacità di generare valore economico sistemico.
È qui che il ragionamento cambia livello. Il tema non è più costruire modelli migliori, ma costruire una capacità operativa che renda l’intelligenza utilizzabile nel tempo, all’interno dei processi reali. In questo contesto i sistemi agentici diventano centrali: entità software capaci di osservare un contesto, ragionare su più fonti, prendere decisioni e agire, imparando nel tempo. Ma anche qui emerge una verità chiave: gli agenti, per essere davvero efficaci, devono vivere dentro un sistema che li sostiene.
Da questa consapevolezza nasce la fondazione a tre livelli che oggi dà forma all’intero progetto.
Il primo livello è la Industrial Data Platform. È la base che rende possibile tutto il resto. Qui vivono gli asset, i processi, gli eventi, gli storici, i log. È il livello che garantisce scalabilità, sicurezza, modularità e monitoraggio continuo. È ciò che permette all’intelligenza di operare in produzione, con dati affidabili e contesto reale.
Il secondo livello è l’Agentic AI Architecture. Qui l’intelligenza prende forma come sistema: agenti specializzati, orchestrati, capaci di collaborare, di scambiarsi informazioni e di agire secondo obiettivi e processi definiti. Non modelli isolati, ma un’architettura che consente di costruire capacità riutilizzabili e governabili.
Il terzo livello è l’Interfaccia Cognitiva. Questo è il punto di contatto con le persone. Non una semplice interfaccia, ma un ambiente cognitivo che rende visibile il ragionamento degli agenti, permette di intervenire, correggere, fornire feedback. È qui che l’AI diventa comprensibile, affidabile e utilizzabile nel lavoro quotidiano, come un sistema che osserva, decide ed esegue in modo naturale.
Questi tre livelli non sono prodotti separati. Funzionano come un ecosistema connesso. L’azienda o l’operatore esprime un’intenzione operativa — capire cosa sta succedendo, valutare cosa conviene fare. L’interfaccia cognitiva traduce questa intenzione in una richiesta strutturata. L’infrastruttura agentica attiva uno o più agenti specializzati che leggono dati e contesto dalla data platform, eseguono analisi e azioni consentite e producono output operativi: report, allarmi intelligenti, piani di intervento, suggerimenti, ticket, simulazioni. Ogni esito viene registrato, ogni feedback viene incorporato, creando un ciclo di apprendimento continuo. Questo genera un effetto di compounding: ogni utilizzo aumenta la qualità del sistema e la fiducia nel tempo.
È proprio questa fondazione che rende possibile il passo successivo: il Farm di Agenti AI per l’industria. Imagin.AI non nasce come un catalogo di soluzioni indipendenti, ma come estensione naturale di una base comune. Gli agenti vivono sopra la stessa infrastruttura, condividono linguaggio operativo, dati e governance. Questo permette di scalare ciò che prima veniva costruito progetto per progetto.
I primi agenti si concentrano su aree dove il valore è immediato e misurabile, come l’analisi degli alert e dei fermi macchina. Sono ambiti trasversali, presenti in quasi tutti i settori industriali, in cui il tempo risparmiato si traduce direttamente in valore economico. Qui l’impatto non è astratto: si misura in riduzione dei tempi di risoluzione, continuità operativa e capacità decisionale.
Questo approccio si riflette anche nel modello di ricavi, pensato per volume e ricorrenza. I principali flussi derivano dall’abbonamento alla piattaforma — che dà accesso alla fondazione tecnologica e all’interfaccia cognitiva — dall’attivazione e utilizzo degli agenti tramite il marketplace, con logiche di subscription o usage-based, e da servizi premium per contesti enterprise e domini ad alta complessità. La piattaforma diventa il moltiplicatore: ogni agente aggiunge valore e ricavi sfruttando la stessa base, senza riprogettare l’intero sistema.
Dietro questa visione c’è un team pensato per renderla reale: competenze di dominio industriale, architettura agentica, data engineering, interfacce cognitive, sicurezza, integrazione e go-to-market. Non un gruppo di generalisti, ma ruoli complementari che coprono l’intera catena del valore.
Oggi quello che stiamo cercando di fare è portare questa evoluzione a un livello successivo: trasformare anni di esperienza, conoscenza e tecnologia in una piattaforma scalabile, capace di abilitare un nuovo modo di usare l’AI nell’industria. Non come progetto, ma come infrastruttura. Non come strumento, ma come capacità continua. Ed è questa coerenza tra visione, tecnologia, mercato e modello di business che rende il progetto credibile agli occhi di un investitore.</video:title><video:description>AI-generated educational video covering Questa storia nasce da un percorso lungo, non da un’intuizione improvvisa.

actuarial neural networks

A combined actuarial neural network (CANN) embeds a GLM into a neural network using a skip connection that directly links the input layer to the output layer (Figure 1).

Figure 1: An example of a CANN - Uncredited

It is essentially a neural network that uses the benchmark GLM’s predictions while learning additional interactions among variables to improve the overall model’s predictive power. There are three common approaches to using a CANN:

The GLM element is non-trainable, so the benchmark GLM is always present and only the network part changes. This is the form of CANN included in the analysis to follow.

The entire network parameter can be trained, meaning the benchmark GLM can be modified.

A trainable credibility weighting can be introduced for the fixed GLM element within the CANN.

While CANN may not generally outperform pure neural networks in minimising the objective loss function, its value for pricing teams lies in uncovering nuanced interactions that can enhance existing GLMs in production.

LocalGLMnet

This structure predicts GLM’s coefficients for each individual record using a neural network, leveraging the GLM’s advantages in terms of explainability. However, it gains predictive accuracy by allowing the coefficients to vary for each record. The LocalGLMnet uses a skip connection (different from that used in the CANN), directly linking the input features to the output layer. This provides a linear term in the model, which bypasses the neural network, and then weights these terms with potentially non-linear weights. 

Successfully training this neural network leaves us with a highly predictive model and a set of beta coefficients (attention weights) for each observation (Figure 2). Now we can interpret the prediction in a familiar way but also analyse the attention weights and how they vary for different predictors.

Figure 2: An example of a LocalGLMnet - Uncredited

Results

Now that we have conceptually described these two new models, let’s road-test them and see how they perform on real-world data. In this case, we use them to predict the frequency of third-party motor liability claims for individual customers, using a publicly available dataset with 680,000 records and 11 features relating to motor policies of a French insurer. This dataset is commonly used in literature on actuarial models and model benchmarking.

We studied CANN and LocalGLMnet and included the GLM and FFNN models for comparison. A simple intercept model is also included for reference. A full description of the implemented models is beyond the scope of this article, so we will focus on high-level results and conclusions from the exercise. A more detailed presentation of this work will be available in an accompanying blog post on Towards Data Science and a GitHub repository (github.com/Karol-Gawlowski/ADSWP_NN ).

Every second and every penny counts; used wisely, these solutions may present an advantage



Table 1 shows the results of a cross-validation (CV) exercise over five folds of the data. In a five-fold CV exercise, the model is fitted once over four partitions of the modelling data, then tested on the fifth unseen partition. This is done five times, with a different unseen partition of data tested each time. The metric used to assess model performance here is the total Poisson deviance, where a lower deviance on the unseen partition is preferred. The ‘pinball score’ of the best neural net model, and of the GLM, is also shown for each partition. This score is essentially the percentage reduction in deviance from a null model to the model of interest.</video:title><video:description>AI-generated educational video covering Combined actuarial neural networks

table 1 shows the results of a cross-validation (cv) exercise over five folds of the data. in a five-fold cv exercise, the model is fitted once over four partitions of the modelling data, then tested on the fifth unseen partition. this is done five times, with a different unseen partition of data tested each time. the metric used to assess model performance here is the total poisson deviance, where a lower deviance on the unseen partition is preferred. the ‘pinball score’ of the best neural net model, and of the glm, is also shown for each partition. this score is essentially the percentage reduction in deviance from a null model to the model of interest.</video:tag><video:tag>level-2</video:tag><video:tag>educational</video:tag><video:category>Education</video:category></video:video></url><url><loc>https://magiacademy.com/video/531ac51a-c962-4221-ba7f-3a4d90545098</loc><lastmod>2026-03-21</lastmod><changefreq>weekly</changefreq><priority>0.8</priority><video:video><video:thumbnail_loc>https://storage.googleapis.com/magi-f7f13.firebasestorage.app/thumbnails/2026-03/explain_how_3blue1brow_create_the_manim_library_for_animation_and_we_can_use_it_531ac51a.jpg</video:thumbnail_loc><video:title>explain how 3blue1brow create the manim library for animation and we can use it for our own</video:title><video:description>AI-generated educational video covering explain how 3blue1brow create the manim library for animation and we can use it for our own at intermediate level</video:description><video:content_loc>https://storage.googleapis.com/magi-f7f13.firebasestorage.app/videos/2026-03/explain_how_3blue1brow_create_the_manim_library_for_animation_and_we_can_use_it_531ac51a.mp4</video:content_loc><video:duration>224</video:duration><video:view_count>1</video:view_count><video:publication_date>2026-03-21T22:19:06.920972+00:00</video:publication_date><video:family_friendly>yes</video:family_friendly><video:tag>explain how 3blue1brow create the manim library for animation and we can use it for our own</video:tag><video:tag>level-2</video:tag><video:tag>educational</video:tag><video:category>Education</video:category></video:video></url><url><loc>https://magiacademy.com/video/710611ad-d9b8-4ab2-9fd3-dc9509b6840a</loc><lastmod>2026-03-21</lastmod><changefreq>weekly</changefreq><priority>0.8</priority><video:video><video:thumbnail_loc>https://storage.googleapis.com/magi-f7f13.firebasestorage.app/thumbnails/2026-03/solution_t_710611ad.jpg</video:thumbnail_loc><video:title>Solution: t</video:title><video:description>Step-by-step solution for: t...</video:description><video:content_loc>https://storage.googleapis.com/magi-f7f13.firebasestorage.app/videos/2026-03/solution_t_710611ad.mp4</video:content_loc><video:duration>174</video:duration><video:publication_date>2026-03-21T22:05:32.103627+00:00</video:publication_date><video:family_friendly>yes</video:family_friendly><video:tag>problem-solving</video:tag><video:tag>math</video:tag><video:tag>level-2</video:tag><video:category>Problem Solving</video:category></video:video></url><url><loc>https://magiacademy.com/video/37d9cadb-280c-4fe1-a69b-637f3913cf6f</loc><lastmod>2026-03-21</lastmod><changefreq>weekly</changefreq><priority>0.8</priority><video:video><video:thumbnail_loc>https://storage.googleapis.com/magi-f7f13.firebasestorage.app/thumbnails/2026-03/explain_me_all_these_topics_in_detail_segment_tree_range_query_point_update_and_37d9cadb.jpg</video:thumbnail_loc><video:title>explain me all these topics in detail Segment tree

# SKIP LIST — THE INTUITION
# =============================================================================
#
# Picture a sorted linked list. Searching it is O(n) — too slow.
#
# Now imagine you add &amp;quot;express lanes&amp;quot; above it, like floors of a building:
#
#   Level 3:  HEAD -----------------------------------------&amp;gt;50 -&amp;gt; None
#   Level 2:  HEAD ----------------&amp;gt; 20 -------------------&amp;gt; 50 -&amp;gt; None
#   Level 1:  HEAD -------&amp;gt; 10 ----&amp;gt; 20 -------&amp;gt; 40 -------&amp;gt; 50 -&amp;gt; None
#   Level 0:  HEAD -&amp;gt; 5 --&amp;gt; 10 ----&amp;gt; 20 -&amp;gt; 30 -&amp;gt; 40 -&amp;gt; 45 -&amp;gt; 50 -&amp;gt; None
#
# To SEARCH for 30:
#   - Start at top-left (HEAD, Level 3)
#   - Go right if next &amp;lt;= target, go down if next &amp;gt; target
#   - Level 3: next is 50 &amp;gt; 30, go DOWN
#   - Level 2: next is 20 &amp;lt;= 30, go RIGHT to 20. Next is 50 &amp;gt; 30, go DOWN
#   - Level 1: next is 40 &amp;gt; 30, go DOWN
#   - Level 0: next is 30 == 30, FOUND!
#
# Each level skips over ~half the nodes, giving O(log n) average time.
#
# WHY skip list for this problem?
#   - O(log n) search, insert, delete on AVERAGE
#   - No worst-case rebalancing spikes (unlike red-black trees)
#   - Simple to code — just linked list pointers + coin flips

che abbiamo messo a fuoco finora è che la realtà sociale non nasce dal nulla, ma dal modo in cui il cervello umano astrae, comprime, comunica e condivide significati fino a sovrapporli al mondo fisico, trasformando un territorio in confine, un oggetto in simbolo, una regola in norma, una convenzione in verità operativa; in questo senso, gli esseri umani non modificano direttamente la materia, ma “piegano” la realtà fisica dentro cornici simboliche collettive che diventano efficaci quando gli altri iniziano ad agire come se fossero reali, e proprio qui si collega sia la riflessione del libro sulla realtà sociale come prodotto delle “cinque C” — creatività, comunicazione, copiatura, cooperazione e comprensione/astrazione — sia la tua intuizione tecnologica, perché costruire tecnologia, in fondo, non significa solo creare strumenti, ma progettare nuove realtà condivise, cioè nuovi sistemi di significato, nuove coordinate di comportamento e nuove dipendenze cognitive; l’articolo su World Labs porta questa logica a un livello ulteriore, mostrando che oggi non stiamo più solo producendo contenuti o rappresentazioni, ma contesti abitabili, mondi sintetici persistenti e programmabili, nei quali la realtà non viene soltanto raccontata ma esperita, e questo rende l’infrastruttura — soprattutto l’API — più potente della semplice visione, perché consente di industrializzare la costruzione di ambienti credibili, trasferendo valore dalla singola opera al sistema che genera mondi; così, la traiettoria che unisce confini, norme, simboli, piattaforme e ambienti 3D è una sola: il passaggio da una realtà sociale costruita lentamente tramite linguaggio, istituzioni e consenso a una realtà sintetica costruibile, iterabile e scalabile tramite infrastrutture tecnologiche, dove il vero potere non sta più soltanto nel far credere qualcosa, ma nel definire i contesti entro cui gli altri percepiscono, agiscono e decidono ciò che è reale; e questa stessa logica si estende naturalmente al modo in cui possiamo leggere e ricostruire il tessuto industriale, che smette di apparire come un insieme statico di fabbriche, settori o infrastrutture e si rivela invece come un sistema vivo fatto di relazioni, flussi, dipendenze, memoria e capacità di adattamento; così come le frontiere o il denaro non sono oggetti ma reti di significato condiviso, anche l’industria non è un inventario di cose ma un organismo che metabolizza risorse, coordina attori, accumula conoscenza e si rigenera o collassa in base alla qualità delle connessioni interne, e questo cambio di prospettiva — da cose a relazioni, da strutture a dinamiche — è lo stesso che permette di comprendere come le realtà sociali emergano e, allo stesso tempo, come possano essere riprogettate; in questo senso, il passaggio introdotto dalle tecnologie come quelle descritte per World Labs diventa decisivo, perché non ci limitiamo più a osservare o interpretare questi sistemi, ma

questa stessa logica si estende naturalmente al modo in cui possiamo leggere e ricostruire il tessuto industriale, che smette di apparire come un insieme statico di fabbriche, settori o infrastrutture e si rivela invece come un sistema vivo fatto di relazioni, flussi, dipendenze, memoria e capacità di adattamento; così come le frontiere o il denaro non sono oggetti ma reti di significato condiviso, anche l’industria non è un inventario di cose ma un organismo che metabolizza risorse, coordina attori, accumula conoscenza e si rigenera o collassa in base alla qualità delle connessioni interne, e questo cambio di prospettiva — da cose a relazioni, da strutture a dinamiche — è lo stesso che permette di comprendere come le realtà sociali emergano e, allo stesso tempo, come possano essere riprogettate; in questo senso, il passaggio introdotto dalle tecnologie come quelle descritte per world labs diventa decisivo, perché non ci limitiamo più a osservare o interpretare questi sistemi, ma acquisiamo la possibilità di simularli, manipolarli e persino costruirne di nuovi attraverso infrastrutture programmabili, trasformando la creatività in un layer operativo capace di generare contesti abitabili, e quindi spostando definitivamente il potere dal singolo elemento alla configurazione delle relazioni che rendono possibile la vita — sociale, economica o industriale — dentro un

The Black-Scholes model 
2.1 Introduction 
In this section we will show how to derive the price of a European call or put option using a 
model under which share prices evolve in continuous time and are characterised at any 
point in time by a continuous distribution rather than a discrete distribution. 
2.2 The underlying SDE 
Suppose that we have a European call option on a non-dividend-paying share tS which is 
governed by the stochastic differential equation (SDE):  
 ( ) t t t dS S dt dZ     
where tZ is a standard Brownian motion. 
The share price process is therefore being modelled as a geometric Brownian motion or 
lognormal model, as discussed previously.  The constants  and  are referred to as the drift 
and volatility parameters respectively. 
Investors are allowed to invest positive or negative amounts in this share.  Investors can 
also have holdings in a risk-free cash bond with price tB at time t .   
This is governed by the ordinary differential equation:  
 t t dB rBdt  
where r is the (assumed-to-be) constant risk-free rate of interest.  Hence:

To check this solution, we define the function 2 1 0 2 ( ) exp[( ) ] t t gt Z S t Z        so that 
( ) t t S gt Z   .  Note that this is a function of t and tZ . 
Recall that the Ito process for standard Brownian motion is: 
 1 0 t t dZ dZ dt   
Now apply Ito’s Lemma to ( )t gt Z , which we write as g for notational ease.  That is:  
 
2 2 1 1 0 2 2 t

gdt gdZ
   
 
                
 
 
Replacing ( , )t g gtZ  with tS , we have the original SDE and the check is complete: 
 t t t t dS Sdt SdZ     
Page 8 CM2-15: The Black-Scholes option pricing formula

Since tZ is normally distributed, tS is lognormally distributed with all of the usual 
properties of that distribution. 
From the formula given for tS we can deduce that: 
                      

So tS has a lognormal distribution with parameters       2
0 log ½ S t and 2t.   
This price process is sometimes called a lognormal process, geometric Brownian motion or 
exponential Brownian motion. 
2.3 The Black-Scholes formula 
Let ( ) f t s be the price at time t of a call option given:  
 the current share price is tS s 
 the time of maturity is T t 
 the exercise price is K. 
Proposition 15.1  (The Black-Scholes formula) 
For such a call option:  
( )
1 2 ( ) ( ) ( ) rT t
t t f tS S d Ke d        
where:

and:   
2 1 d d T t     
and ( )z is the cumulative distribution function of the standard normal distribution. 
This formula is the Garman-Kohlhagen formula found on page 47 of the Tables.  Here the dividend 
rate q is equal to zero. 
For a put option we also have ( )
2 1 ( ) ( ) ( ) rT t
t t f tS Ke d S d        where 1d and 2d are as 
defined above.   
Question 
Starting from the formula for the price of a call option given in Proposition 15.1, use put-call 
parity to derive the formula just given for the price of a put option.

We will give two proofs of this result, one here using the partial differential equation (PDE) 
approach and the other in a later chapter using the martingale approach. 
2.4 The PDE approach 
Here we use Ito’s Lemma to derive an expression for the price of the derivative as a function, ,f 
of the underlying share price process tS .  Here tS again refers to the share price excluding any 
dividends received.  This method involves the construction of a risk-free portfolio, which in an 
arbitrage-free world must yield a return equal to the risk-free rate of return.   
An expression for df(t,St) 
We first use Ito’s Lemma to write a stochastic differential equation (SDE) for the change in the 
derivative price as a function of the change in the share price.  Here ( , )t df t S means the change in 
the value of the derivative over a very small time period. 
Given the Ito process: 
 t t t t dS Sdt SdZ     
which is the SDE for geometric Brownian motion, with drift and volatility functions for tS of  tS 
and  tS respectively, 
then applying Ito’s Lemma to the function ( , )t f tS , we have:

We are assuming here that there is no net investment into or out of the portfolio. 
Note that this portfolio strategy is not self-financing.  That is, the pure investment gain 
derived above is not equal to the instantaneous change in the value of the portfolio,

Self-financing portfolios are defined formally later in the course. 
Note also that the right-hand side of the above expression, which represents the pure investment 
gain over the interval  [ , ) t t dt , involves the share price, which is random.  However, the value of

Now note that the expression for ( ) f t t s df tS dS 

In this section we will show how to derive the price of a European call or put option using a 
model under which share prices evolve in continuous time and are characterised at any 
point in time by a continuous distribution rather than a discrete distribution.

governed by the stochastic differential equation (SDE):

The share price process is therefore being modelled as a geometric Brownian motion or 
lognormal model, as discussed previously.  The constants  and  are referred to as the drift 
and volatility parameters respectively. 
Investors are allowed to invest positive or negative amounts in this share.  Investors can 
also have holdings in a risk-free cash bond with price tB at time t .   
This is governed by the ordinary differential equation:  
 t t dB rBdt  
where r is the (assumed-to-be) constant risk-free rate of interest.  Hence:

this price process is sometimes called a lognormal process, geometric brownian motion or

let ( ) f t s be the price at time t of a call option given:

Here  is the drift coefficient and  is known as the diffusion coefficient (or volatility). 
Standard Brownian motion is obtained when   0 ,  1 and

It turns out that Brownian motion is the only process with stationary independent increments and

Strategic Design Concepts (Large-scale system design): These deal with how multiple domains and teams interact.
Context Mapping: Defines relationships between bounded contexts.
Context Map Patterns: Different ways contexts interact:
Partnership
Shared Kernel
Customer–Supplier
Conformist
Anticorruption Layer
Open Host Service
 Published Language
 Separate Ways
Big Ball of Mud  

Advanced Modeling Concepts: These concepts help refine the domain model.
Model-Driven Design: The code structure reflects the domain model directly.
Supple Design: Design techniques that keep the model flexible and expressive. Key patterns inside Supple Design:
Intention-Revealing Interfaces
Side-Effect-Free Functions
Assertions
Conceptual Contours
Standalone Classes
Closure of Operations

Integration Patterns (Advanced Context Interaction): Used when multiple bounded contexts communicate.
Anticorruption Layer: A translation layer that prevents an external model from corrupting your domain model.
Open Host Service: Defines a protocol or API that other contexts can use.
Published Language: Shared communication format or schema between contexts.
 
Advanced Design Refinement: Concepts for improving models during evolution.
Continuous Refactoring of the Model: The domain model should evolve with deeper insight.
Specification Pattern: Encapsulates business rules and queries as reusable objects.
Declarative Design: Express domain logic declaratively rather than procedurally.</video:title><video:description>AI-generated educational video covering explain all these concepts from the following book : Domain-Driven Design by Eric Evans:

Simply adding Gaussian noise to LLMs (one step—no iterations, no learning rate, no gradients) and ensembling them can achieve performance comparable to or even better than standard GRPO/PPO on math reasoning, coding, writing, and chemistry tasks. We call this algorithm RandOpt.

To verify that this is not limited to specific models, we tested it on Qwen, Llama, OLMo3, and VLMs.

What&amp;apos;s behind this? We find that in the Gaussian search neighborhood around pretrained LLMs, diverse task experts are densely distributed — a regime we term Neural Thickets.

Beyond language models and vision-language models, we observe similar effects in diffusion models. Here, one can think of “color thickets,” where certain regions of parameter space preferentially generate images with specific color palettes or visual styles.

Some implications: 
- Pretrained models are distributions.
- Pretraining is all we need (?).
- Understanding pretraining =(?) characterizing the multi-task loss landscape.
- Post-training need less than we think (?).

Formation of Unsaturated and Saturated Solutions

(Take about 100 g of water in a beaker, add to it 5g of table sugar, and stir it, The sugar will dissolve in water. Then add another 5g of sugar and stir. This will also dissolve. This solution is called an unsaturated solution A solution which can dissolve more amount of a solute at a particular temperature is called an unsaturated solution. Continue adding sugar in the above solution. As the quantity of sugar in water increases, its dissolution will become more difficult/A stage comes when no more sugar will dissolve in water at this temperature. Arry more sugar added at this stage will settle down at the bottom of the beaker. This

solution is called a saturated solution at a particular temperature of the process) A solution in which the maximum amount of the solute has been dissolved in a particular amount of a solvent at a particular temperature is called a saturated solution.)

Different solutes have different solubilities in a particular solvent. For example, if the solutions of table sugar and sodium chloride are prepared, it is found that 36 g of sodium chloride can dissolve in 100 g of water at 20°C to give a saturated solution. Against this 203.9 g of table sugar can dissolve in water at 20°C to give its saturated solution. In other words, the solubility of table sugar in water is far greater than that of sodium chloride at 20°C. This is due to the fact that sugar molecules are larger than salt ions, so more water molecules can surround a single sugar molecule, causing it to dissolve in larger amounts.</video:title><video:description>AI-generated educational video covering 1.7 Formation of Unsaturated and Saturated Solutions

4 Message Passing (20 points)
Consider the following problem of multiplying two 𝑛 × 𝑛 input matrices, 𝐴 and 𝐵, using
message passing. Suppose there are 𝒏 processors (𝑛 = 2𝑚) in a 1-D mesh with wraparound
connection. Each processor 𝑖 (0 ≤ 𝑖 &amp;lt; 𝑛) initially has the 𝒊
𝒕𝒉 row of 𝑨 and 𝒊
𝒕𝒉 row of 𝑩 stored
in local memory and computes the 𝒊
𝒕𝒉 row of the output matrix 𝑪. You can assume all
elements of the output matrix C are already initialized to 0. In this message passing program
we will be using blocking send/receive (no broadcast operations) and analyze its performance.
Assume you can only send and receive one element at a time.
a) Write a high-level description of your message passing program to be executed on processor
𝑖 to perform matrix multiplication as described above. Write the pseudo code for your
algorithm using blocking send/receive commands. Make sure your program does not
deadlock. (6 points)
High-level description:
To calculate the 𝒊
𝒕𝒉 row of 𝑪, you need to multiply the 𝒊
𝒕𝒉 row of 𝑨 and 𝒊
𝒕𝒉 column of
𝑩 . Since the processor 𝑖 has only one element of each column of 𝑩, the processor
needs to receive the remaining elements from the other processors. So, in the first
iteration, the processors will first calculate the first column of output 𝑪, by circular 
upshifting (or circular left shift in terms of processor connections) the elements of the
first column of 𝑩. Similarly, in each iteration, processor 𝑖 will locally compute the
partial sum (C[i][j]) with the available element of the matrix 𝑩 and send it to processor
𝑖 − 1.

4 Message Passing (20 points)
Consider the following problem of multiplying two 𝑛 × 𝑛 input matrices, 𝐴 and 𝐵, using
message passing. Suppose there are 𝒏 processors (𝑛 = 2𝑚) in a 1-D mesh with wraparound
connection. Each processor 𝑖 (0 ≤ 𝑖 &amp;lt; 𝑛) initially has the 𝒊
𝒕𝒉 row of 𝑨 and 𝒊
𝒕𝒉 row of 𝑩 stored
in local memory and computes the 𝒊
𝒕𝒉 row of the output matrix 𝑪. You can assume all
elements of the output matrix C are already initialized to 0. In this message passing program
we will be using blocking send/receive (no broadcast operations) and analyze its performance.
Assume you can only send and receive one element at a time.
a) Write a high-level description of your message passing program to be executed on processor
𝑖 to perform matrix multiplication as described above. Write the pseudo code for your
algorithm using blocking send/receive commands. Make sure your program does not
deadlock. (6 points)
High-level description:
To calculate the 𝒊
𝒕𝒉 row of 𝑪, you need to multiply the 𝒊
𝒕𝒉 row of 𝑨 and 𝒊
𝒕𝒉 column of
𝑩 . Since the processor 𝑖 has only one element of each column of 𝑩, the processor
needs to receive the remaining elements from the other processors. So, in the first
iteration, the processors will first calculate the first column of output 𝑪, by circular 
upshifting (or circular left shift in terms of processor connections) the elements of the
first column of 𝑩. Similarly, in each iteration, processor 𝑖 will locally compute the
partial sum (C[i][j]) with the available element of the matrix 𝑩 and send it to processor
𝑖 − 1.
Processor 𝑖:
 a_row = A[i][:]; #Assuming A is accessed row wise
b_row = B[i][:]; #Assuming B is accessed row wise for
j=0 to n-1
#Computation
C[i][j] = 0 #not necessary as it is stated in the question that C is initialized for
k=0 to n-1
 C[i][j] += a_row[(i+k)%n] * b_row[j];
 #Communication – circular upshift If (i
%2 == 0) # Even processors send first
send(b_row[j], Processor((i-1+n)%n) );
receive(b_buff, Processor((i+1)%n) );
b_row[j] = b_buff; else # Odd
processors receive first receive(b_buff,
Processor((i+1)%n)); send(b_row[j],
Processor((i-1+n)%n));
