Changing paradigms in the management of complicated diverticulitis

Complicated colonic diverticulitis remains a frequent cause of hospital admissions in Western countries, associated with significant morbidity and health care utilization. Complications include abscess formation, perforation, sepsis, fistulas, and colonic stenosis, which may be present at initial presentation or develop during the disease course. Approximately 10%-20% of hospitalized diverticuliti

Interest Rate Modelling for Counterparty Credit Risk and Credit Valuation Adjustment

This thesis evaluates three interest rate models the HW1F, HW2F, and CIR++ from a risk management perspective. Through simulation, we examine their ability to generate realistic yield curves, as well as their impact on exposure metrics and CVA in different market environments. The CIR++ model consistently produces the highest and most conservative PFE estimates while also maintaining calibration

Channel Orthogonalization With Reconfigurable Surfaces : General Models, Theoretical Limits, and Effective Configuration

We envision a future in which multi-antenna technology effectively exploits the spatial domain as a set of non-interfering orthogonal resources, allowing for flexible resource allocation and efficient modulation/demodulation. We may refer to this paradigm as orthogonal space-division multiplexing (OSDM). On the other hand, reconfigurable intelligent surface (RIS) has emerged as a promising technol

Between green and safety : navigating sustainability and public health risks in growing media

Growth Hormone Improves Ovarian Follicle Health in Premature Ovarian Failure Mice by Reducing Apoptosis : (GH Improves Ovarian Follicle Health in POF Mice by Reducing Apoptosis)

Premature ovarian failure (POF) is a perplexing condition in women characterized by cessation of oocyte production in the ovaries. Despite numerous proposed causes for the development of POF, the actual cause of the most POF cases remains unknown. Given that POF significantly affects fertility and is a devastating diagnosis for women, there is an urgent need for the development of new therapies ai

Forced Into an Ableist Narrative? The Swedish Covid Association’s Quest for Recognition

During the COVID-19 pandemic, the Swedish Covid Association (SCA) was established to represent individuals with Long COVID (LC). The unique Swedish response to the pandemic, characterized by minimal restrictions, serves as the backdrop for the SCA’s efforts to highlight the specific needs of LC patients, who were largely excluded from pandemic policies and protective measures.

Portfolio Optimization with Machine Learning: Predicting Market Returns and Portfolio Weights

Att investera sina pengar på ett smart sätt – så kallad portföljoptimering – är en grundläg- gande utmaning inom finans. Traditionellt har detta byggt på att man försöker förutspå framtida avkastning och hur olika tillgångar samvarierar. Men dessa uppskattningar är ofta osäkra och kan leda till felbeslut. I takt med att maskininlärning blivit allt vanligare inom finansvärlden har nya metoder utvecPortfolio optimization is a central problem in finance, with traditional approaches of- ten relying on forecasts of expected returns and covariances. With the growing adoption of machine learning in finance, return forecasting using ML techniques has become in- creasingly common. More recently, an alternative approach has been proposed where the portfolio weights are learned directly, bypassing th
