Coriolis force acting on near-surface horizontal flows during simulations of flux emergence produces a tilt angle consistent with Joy's law on the Sun
Joy's law describes the tilt of bipolar active regions on the Sun away from an east-west orientation, where the flux of the polarity concentrated at the prograde side tends to be closer to the equator than the polarity on the retrograde side. Joy's law is attributed to the Coriolis force because of the observed increase in tilt angle at higher latitudes. This tilt plays a crucial role in some solar dynamo models. Our goal is to model the effects of the Coriolis force on a flux tube as it rises …

Validation of the MySurgeryRisk Algorithm for Predicting Complications and Death after Major Surgery: A Retrospective Multicenter Study Using OneFlorida Data Trust
Despite advances in surgical techniques and care, postoperative complications are prevalent and effects up to 15% of the patients who underwent a major surgery. The objective of this study is to develop and validate models for predicting postoperative complications and death after major surgery on a large and multicenter dataset, following the previously validated MySurgeryRisk algorithm. This retrospective, longitudinal and multicenter cohort analysis included 508,097 encounters from 366,875 a…

Comparative Firm-Level Analysis of ESG and Sentiment Effects on Stock Market Performance: Evidence from 16 Companies Using Retrofitted Sentiment Embeddings
This study investigates how emotion-specific sentiment embedded in financial news headlines interacts with firm-level ESG (Environmental, Social, and Governance) ratings to influence stock return behavior. Using data from 16 firms and integrating retrofitted word embeddings with ESG metrics, the analysis evaluates three hypotheses: (1) emotion-specific sentiment independently predicts stock returns; (2) its moderating effect varies across ESG dimensions; and (3) positive (negative) sentiment am…

Retrospective score tests versus prospective score tests for genetic association with case-control data
Since the seminal work by Prentice and Pyke (1979), the prospective logistic likelihood has become the standard method of analysis for retrospectively collected case-control data, in particular for testing the association between a single genetic marker and a disease outcome in genetic case-control studies. When studying multiple genetic markers with relatively small effects, especially those with rare variants, various aggregated approaches based on the same prospective likelihood have been de…
