Regularity Estimates for Fully Nonlinear Dead‐Core Problems With a Hamiltonian Term

Mathematische Nachrichten, EarlyView.
ABSTRACT In this paper, we present a problem involving fully nonlinear elliptic operators with Hamiltonian, which can present a singularity or degenerate as the gradient approaches the origin. The model studied here, allows the appearance of plateau zones, i.e., unknown regions of the domain in which the non‐negative solutions vanishes.

Cononsolvency‐Assisted Fabrication of Hydrogels and Microgels With Tunable Porosity, Diffusivity and Stiffness

Macromolecular Rapid Communications, EarlyView.
The cononsolvency of poly(dimethyl acrylamide‐co‐hydroxyethyl acrylamide) copolymers in water‐acetonitrile mixtures enables the synthesis of hydrogels with finely tuned porosity. Optimized for droplet‐based microfluidics, this approach facilitates the fabrication of porous microgels with tunable mechanical and diffusion properties, offering precise ...

Experimental Study on Polymer–Polymer Interfacial Thermal Resistance

Macromolecular Theory and Simulations, Volume 34, Issue 2, March 2025.
Interfacial thermal resistance (ITR) in polymer–polymer interfaces is experimentally measured in this paper by the multi‐layered bulk sample approach. Based on numerical simulation and experimental verification, new techniques of layer‐overlapping samples are developed.

A Geometric Interpretation for the Algebraic Properties of Second‐Order Ordinary Differential Equations

Mathematical Methods in the Applied Sciences, Volume 48, Issue 6, Page 6912-6917, April 2025.
ABSTRACT Nowadays, a substantial portion of investigations concerning the symmetry analysis of differential equations predominantly adhere to a framework comprising the following key procedures: (i) the derivation of symmetries, (ii) the determination of an optimal system, (iii) the utilization of these symmetries to construct invariants or ...

Optimized Gradient Waveforms for Tensor‐Valued Diffusion MRI Under Time‐Dependent Diffusion Using Double‐Isotropic Matched Encoding (DIME)

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose Spherical and linear b‐tensor encoding (STE and LTE) enables quantification of microscopic diffusion anisotropy and diffusional variance. However, such waveforms are often variably sensitive to time‐dependent diffusion, causing rotational variance and spectral mismatch.

Different Stakeholders, Different Pathways: How Capacity Profiles Shape Managerial Priorities for Beneficiaries and Staff in Decision‐Making

Nonprofit Management and Leadership, EarlyView.
ABSTRACT This study investigates how combinations of organizational capacities shape nongovernmental organization (NGO) managers' prioritization of staff and beneficiaries. While stakeholder theory identifies which stakeholders' interests attract attention, it offers limited guidance on how managers ultimately prioritize among stakeholders in decision ...

Globalizing Comparative Public Administration With Integrative Contextualization: State Autonomy in the Developmental Path of Hong Kong and Singapore

Public Administration and Development, EarlyView.
ABSTRACT The lack of a common variable for comparison has been a major obstacle to the development of Comparative Public Administration (CPA). State autonomy enables an integrative contextualization approach, allowing both the analysis of contextual individual country experiences and the generation of generalized comparable knowledge.

Towards more reliable interdisciplinary modelling of global human–environment dynamics driving biodiversity change

People and Nature, EarlyView.
Abstract Environmental problems are typically vast, urgent and complex. Confronted with such problems, we are often tempted to act fast by pulling together little bits and pieces from different fields and simply adding these to pre‐existing models and frameworks.

Genetic Investigation in Fetal Growth Restriction: An Integrated Approach for Clinical Practice

Prenatal Diagnosis, EarlyView.
ABSTRACT International guidelines recommend genetic testing when fetal growth restriction (FGR) accompanies structural anomalies, but recommendations for apparently isolated FGR remain variable, particularly regarding gestational age thresholds and the role of exome sequencing (ES). Interpretation is difficult because studies define FGR inconsistently,

Reconsidering how to dry orthodox seeds for improved ex situ conservation outcomes

PLANTS, PEOPLE, PLANET, EarlyView.
Ex situ seed conservation is an essential tool in our efforts to conserve wild and cultivated plant diversity, as mentioned in the Global Strategy for Plant Conservation and the Sustainable Development Goals. While there are established standards which seed banks follow, it is important that we continue to evaluate protocols and optimize processes ...
