Economic theory does not always specify the functional relationship between dependent and explanatory variables, or even isolate a particular set of covariates. This means that model uncertainty is pervasive in empirical economics. In this paper, we indicate how Bayesian semi-parametric regression methods in combination with stochastic search variable selection can be used to address two model uncertainties simultaneously: (i) the uncertainty with respect to the variables which should be included in the model and (ii) the uncertainty with respect to the functional form of their effects. The presented approach enables the simultaneous identification of robust linear and nonlinear effects. The additional insights gained are illustrated on applications in empirical economics, namely willingness to pay for housing, and cross-country growth regression.

Developing high-precision models of the nuclear force and propagating the associated uncertainties in quantum many-body calculations of nuclei and nuclear matter remain key challenges for ab initio nuclear theory. In this Letter, we demonstrate that generative machine learning models can construct novel instances of the nucleon-nucleon interaction when trained on existing potentials from the literature. In particular, we train the generative model on nucleon-nucleon potentials derived at second and third order in chiral effective field theory and at three different choices of the resolution scale.

Background: Alzheimer's disease (AD) brains commonly exhibit various co-morbid pathologies, with cerebral amyloid angiopathy (CAA) being the most prevalent, affecting 70-90% of patients. CAA can be restricted to medium and large vessels or extend to capillaries. Additionally, AD patients often show pathologies involving phosphorylated-TDP-43 (pTDP-43) and alpha-synuclein (αSyn), typically demonstrating an amygdala-predominant subtype.

Purpose: Real-time risk monitoring is critical but challenging in intensive care units (ICUs) due to the lack of real-time updates for most clinical variables. Although real-time predictions have been integrated into various risk monitoring systems, existing systems do not address uncertainties in risk assessments. We developed a novel framework based on commonly used systems like the Sequential Organ Failure Assessment (SOFA) score by incorporating uncertainties to improve the effectiveness of real-time risk monitoring.

Background: Physicians faced increased workloads during the COVID-19 pandemic, which exposed them to considerable physical and psychological stress. Gaining insight into shapers of job morale of physicians can help healthcare administrators assess the effectiveness of current work conditions and support systems, enabling them to develop policies that improve work environments and prepare healthcare systems for future resurgences of COVID-19 and other future unknown challenges. Therefore, the present study aimed to improve the understanding of physicians' experiences of job morale in Kazakhstan during the COVID-19 pandemic.

Background: Chronic obstructive pulmonary disease (COPD) continues to be a significant issue, leading to premature death or reduced quality of life. It's important to assess the current burden of COPD and its risk factors on a geographical basis to guide health policy.
Methods: Data on the prevalence, deaths, and disability-adjusted life years (DALYs) related to COPD, and risk-attributable burden were obtained from the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2021 database.
