The Cardiac “Flip” Sign: A Simple Sonographic Marker for “Mirror Image Configuration” of the Great Arteries

ABSTRACT We hereby describe a new sonographic sign, the cardiac “flip” sign, to help in the prenatal detection of a right sided aortic arch with a right sided ductus arteriosus. This sign depends on pattern recognition where the sonologist/sonographer needs to obtain a cardiac sw...

Regimes Matter: Regime-Based Dynamic Asset Allocation Using Neural Networks

We study Merton's optimal portfolio problem in a market responsive to macroeconomic regimes, as characterized by VIX. Instead of solving the traditional Hamilton-Jacobi-Bellman equation, we train an artificial neural network (ANN) to learn the optimal allocation as a feedback fun...

The Fox Versus the Hedgehog: Firm Survival During Unprecedented Crises

This paper examines how sales channel diversification influences firm resilience during the COVID crisis. Drawing on a series of logit regressions analyzing 11,662 firms across 31 developing countries, we find that firms embodying an open mind-set and a diverse array of sales cha...

Age and Race Differences in the Association Between Social Support and Leisure-Time Physical Activity Among Adults With Cognitive Difficulty: Evidence From the 2023 BRFSS

Purpose To examine the association between perceived social/emotional support (PSES) and leisure-time physical activity (LTPA) among U.S. adults with self-reported cognitive disabilities, and to explore moderation by age and race. Design Cross-sectional analysis of 2023 Behaviora...

From influence to de-influence: exploring the impact of negative feedback by social media influencers

Purpose This paper aims to address the academic research gap on “de-influencing,” where influencers share negative feedback about brands. Specifically, the authors define de-influencing, explore its impact on consumers’ attitudes toward targeted brands (H1a and H1b) and examine i...

Unlocking Organizational Support Through Psychological Empowerment: Identification and Test of Transformational Leadership as a Catalyst of Perceived Organizational Support

Organizational support theory (OST) explains how employees develop and respond to beliefs about their organization, with perceived organizational support (POS) representing a central construct within this framework. Integrating psychological empowerment theory, we examine an intr...

Larval crowding in Culex pipiens generates cumulative cascading effects under changing environmental conditions

Density-dependent population regulation is a fundamental driver in the population dynamics of living systems, ensuring a balanced and sustainable maintenance in nature. It has been suggested that the adverse developmental and morphological effect of high larval density in contain...

The postsynaptic scaffolding protein SAPAP3 shapes mitochondrial activity: the case of Huntington’s disease

Abstract Postsynaptic scaffolding protein SAP90/PSD95-associated protein 3 (SAPAP3) modulates cortico-striatal signalling and regulates the maintenance of synaptic structure. Notably, SAPAP3 defects have been reported in several human psychiatric disorders that share pathophysiol...

Parametric Study of Yields and Properties of Corn Stover-Derived Hydrothermal Liquefaction Products by Using Statistical Approaches

Hydrothermal liquefaction (HTL) of lignocellulosic biomass produces multiple product fractions, including solid residue (SR), heavy bio-oil (HBO), aqueous phase (AP), and light bio-oil (LBO). This study mainly applied principal component analysis (PCA) and regression modeling to...

Distributed semi-speculative parallel anisotropic mesh adaptation

Abstract This paper presents a distributed memory method for anisotropic mesh adaptation that is designed to avoid the use of collective communication and global synchronization techniques. In the presented method, meshing functionality is separated from performance aspects by ut...

Collaboration and Co-Management Ahead of Permitting: Understanding How Actors and Their Interactions Lead to Non-Optimal Shoreline Projects

Living shorelines are widely promoted as nature-based solutions to coastal erosion and wetland protection, yet hardened shoreline structures continue to dominate even in jurisdictions with explicit policy mandates prioritizing living shorelines. In this research, we examine why n...
