Dual‐Plane Engineered GO‐Shielded GaN Core–Shell Nanowires for Cl−‐Resilient and Durable Seawater Splitting Photoelectrodes

Carbon Energy, EarlyView.
The double‐bond phenomenon enables dual energy band mechanisms that enhance the efficiency of seawater splitting. Atomic interactions at the GO/GaN interface encompass various configurations, such as van der Waals interactions, covalent interactions, type‐II and Z‐scheme alignments, and chloride‐ion repulsion.

Copula‐based joint modelling of emergency department visits with time‐varying dependence

Canadian Journal of Statistics, EarlyView.
Abstract Jointly modelling multiple correlated count time series is essential in health services research, where outcomes like emergency visits for mental health and substance use often evolve together. Ignoring these dependencies can obscure meaningful trends and limit the effectiveness of policy evaluation.

Trade Measures—Relationships and Implications

International Journal of Finance &Economics, EarlyView.
ABSTRACT Various value‐added trade measures have been developed to address the concern in the growing volume of trade in intermediates that are double counted when crossing international borders more than once. This paper raises a query and makes an inquiry into the query.

Synthesis, Cytotoxicity, and Apoptosis‐Associated Cell Death Activity of an Isatin‐Containing Pyrimidine‐Derived Cu(II) Complex

Journal of Applied Toxicology, EarlyView.
ABSTRACT A Cu(II) complex derived from a pyrimidine with the isatin group was synthesized and tested for its cytotoxic effects on A549 lung cancer and MCF‐7 breast cancer cell lines, as well as its effects on apoptosis‐associated cell death and cell cycle regulation in A549 cells. To evaluate cytotoxicity, MTT assays were performed at 24, 48, and 72 h,

Learning and Predicting the Nonlinear Variability of X-Ray Binaries with the Koopman Operator

The Astrophysical Journal Supplement Series
X-ray variability in compact-object binaries encodes the nonlinear dynamics of corona–jet interactions and accretion disk instabilities. Standard timing techniques characterize periodic and quasiperiodic variability well, but do not model underlying ...

Data-Driven Dynamic State Estimation Framework Using a Koopman Operator-Based Linear Predictor

IEEE Access
Dynamic state estimation (DSE) is a fundamental task in many fields, including control systems, robotics, and signal processing. Traditional DSE methods, which rely on mathematical models to describe system dynamics, are often limited in their ...

Cooperative braking of urban rail vehicles with Koopman model predictive control

IET Control Theory & Applications, 2023
Braking control of urban rail vehicles with multiple carriages is critical to ensure the safe operation of urban rails. However, existing decentralized braking control methods lead to the inconsistent speed and excessive coupler force among carriages ...

Where Is the Take in Give and Take? A Review of Empathy Effects on Workplace Outcomes for Both Givers and Receivers

Journal of Organizational Behavior, EarlyView.
ABSTRACT There is increasing interest in understanding and recognition of the importance of empathy effects at work. However, despite the two‐party nature of empathy, little research has distinguished between empathy‐giving versus empathy‐receiving, or between empathy‐giver versus receiver.

Representing Neural Network Layers as Linear Operations via Koopman Operator Theory

CoRR
The strong performance of simple neural networks is often attributed to their nonlinear activations. However, a linear view of neural networks makes understanding and controlling networks much more approachable. We draw from a dynamical systems view of neural networks, offering a fresh perspective by using Koopman operator theory and its connections ...

Emotional Ambivalence Contextualized: The Antecedents and Consequences of Daily Affective Profiles During Pregnancy

Journal of Organizational Behavior, EarlyView.
ABSTRACT Research has increasingly highlighted the prevalence of emotionally ambivalent experiences for employees at work, with several self‐regulatory benefits emerging. Yet we do not have a full understanding of which work‐related contexts yield generative or maladaptive consequences of emotional ambivalence.
