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

open access: yesCanadian 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.

Bridging computational and clinical strategies for presurgical identification of epileptogenic networks

open access: yesEpilepsia Open, EarlyView.
Abstract Objective About one third of epilepsy patients are drug‐resistant. Resective epilepsy surgery remains a key treatment option but depends critically on accurate identification of the seizure onset zone (SOZ), which is still guided mainly by subjective visual inspection of electrophysiological signals.

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

open access: yesIEEE 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 ...

Trade Measures—Relationships and Implications

open access: yesInternational 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

open access: yesJournal 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,

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

open access: yesJournal 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.

Koopman Operator Methods in Structural Health Monitoring: A Systematic Review Towards Hybrid Physics–Data Frameworks

open access: yesApplied Sciences
Structural health monitoring (SHM) is essential for the safety and long-term performance of civil and mechanical infrastructure, yet traditional vibration-based approaches often struggle with nonlinear behavior and environmental variability.

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

open access: yesJournal 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.

Deep Embedding Koopman Neural Operator-Based Nonlinear Flight Training Trajectory Prediction Approach

open access: yesMathematics
Accurate flight training trajectory prediction is a key task in automatic flight maneuver evaluation and flight operations quality assurance (FOQA), which is crucial for pilot training and aviation safety management. The task is extremely challenging due
