Ultrasound features in early pregnancy for predicting abnormal karyotype in first‐trimester miscarriage

Ultrasound in Obstetrics &Gynecology, EarlyView.
ABSTRACT Objective To investigate whether combining abnormal morphological features observed on ultrasound in live pregnancies that ended in a first‐trimester miscarriage can predict an abnormal karyotype. Methods This retrospective observational cohort study was conducted at the early‐pregnancy assessment unit at University College London Hospital ...

Measuring Teamwork Competencies Cross‐Culturally Through Computerized Adaptive Testing: Implications for Human Resource Management

Human Resource Management Journal, EarlyView.
ABSTRACT This article examines the psychometric properties of a Computerized Adaptive Test for Measuring Teamwork Competencies (CAT‐TWC). Using item response theory and a multicultural team framework, we examine the dimensionality, precision, and measurement invariance of the measures obtained with the CAT‐TWC in a first study with participants from ...

Blubber Thickening Driven by UCP1 Inactivation: Insights from a Cetacean‐Like Transgenic Mouse Model

Integrative Zoology, EarlyView.
UCP1 inactivation of cetaceans in mice drives BAT whitening and iWAT hyperplasia, promoting fat accumulation for aquatic adaptation. Abstract Cetaceans possess thick blubber, a specialized adipose tissue essential for thermal insulation, a streamlined body form, energy storage, and buoyancy. However, the mechanisms that underpin this adaptation are not

From Block-Oriented Models to the Koopman Operator: A Comprehensive Review on Data-Driven Chemical Reactor Modeling

Mathematics
Some chemical reactors exhibit coupled dynamics with multiple equilibrium points and strong nonlinearities. The accurate modeling of these dynamics is crucial to optimal control and increasing the reactor’s economic performance. While neural networks can

Koopman Operator-Based Detection-Isolation of Cyberattack: A Case Study on Electric Vehicle Charging [PDF]

American Control Conference
One of the key challenges towards the reliable operation of cyber-physical systems (CPS) is the threat of cyberattacks on system actuation signals and measurements.

Lost in Evaluation: The Intricacies of First‐ and Second‐Order Evaluations in Auditors' Promotion Committees in the Big 4 Audit Firms

Contemporary Accounting Research, EarlyView.
ABSTRACT The evaluation of auditors in the Big 4 audit firms has largely remained a “black box” in accounting and audit research. Little is known about how these processes operate within audit firms or how they relate to promotion decisions. This study addresses this gap by providing direct insight into promotion committee decision‐making.

Recursive Forward-Backward EDMD: Guaranteed Algebraic Search for Koopman Invariant Subspaces

IEEE Access
The implementation of the Koopman operator on digital computers often relies on the approximation of its action on finite-dimensional function spaces. This approximation is generally done by orthogonally projecting on the subspace.

Volunteering While Researching Conflict and Violence: Reflections on Listening, Solidarity, and Decoloniality in Myanmar's Borderlands

Asia Pacific Viewpoint, EarlyView.
ABSTRACT Scholars working on conflict and violence often engage with local organisations, yet the methodological and ethical implications of volunteering‐while‐researching are rarely discussed in writing. This article contributes to debates on decolonizing research by conceptualising volunteering‐while‐researching as a practice that—while imbued with ...

A Koopman-Theoretic Approach to Car-Following and Multi-Lane Interaction Modeling

IEEE Open Journal of Intelligent Transportation Systems
This paper presents a Koopman operator-based approach for the car-following model using SwarmDMD, a dynamic mode decomposition (DMD)-type algorithm designed to capture multi-agent interactions.
