The Penalty resolution of the spectral element discretization of the time dependent Darcy equations

Boundary Value Problems
The time-dependent Darcy system, when discretized in time using the implicit Euler scheme and in space using the spectral element method, can be efficiently solved using the penalty method.

Disentangling Aleatoric and Epistemic Uncertainty in Physics‐Informed Neural Networks: Application to Insulation Material Degradation Prognostics

Advanced Intelligent Systems, EarlyView.
Physics‐Informed Neural Networks (PINNs) provide a framework for integrating physical laws with data. However, their application to Prognostics and Health Management (PHM) remains constrained by the limited uncertainty quantification (UQ) capabilities.

One‐Shot Multimaterial 3D Printing of a Flexible Spine for a Robotic Fish Prototype

Advanced Intelligent Systems, EarlyView.
A one‐shot multimaterial 3D printing approach enables a monolithic soft robotic fish integrating a compliant spine and rigid vertebrae. Electromagnetic linear actuators drive tendon‐based transmission, producing controlled tail oscillations. Finite element modeling and experiments show strong agreement, while optimized material selection improves ...

Talk to Your Data: An Agentic Artificial Intelligence‐Driven Decision‐Support Framework for Prosumer Energy Optimization and Recommendations

Advanced Intelligent Systems, EarlyView.
An agentic AI‐driven decision‐support framework for prosumers is proposed, integrating PV generation, load profiling, and multihorizon optimization within a four‐agent architecture. The approach significantly reduces grid dependence, enhances self‐sufficiency and prevents system oversizing.

Design Optimization of Soft Fabric Pneumatic Actuators

Advanced Intelligent Systems, EarlyView.
This study presents a systematic optimization framework for elongating and bending fabric‐based soft pneumatic actuators. After a preliminary design‐space reduction, the framework minimizes energy consumption under mechanical performance constraints by integrating validated finite element modeling with statistical surrogate models. Optimal designs were

Lost in aggregation? On the importance of local food price data for food poverty estimates

American Journal of Agricultural Economics, EarlyView.
Abstract This paper explores within‐country variations in food price dynamics and food poverty estimates by employing local market price data and national consumer price index (CPI) data. Our results show that national CPI data may be useful for approximating national trends but they fail to detect and identify spatial variations in local trends, which

Kinetic Analysis of Transmetalation at Prototypical Nickel(II) Catalyst Species: Rates, Mechanisms, and Implications for Catalysis

Angewandte Chemie, EarlyView.
A 31P{1H} NMR method enabling direct measurement of transmetalation at Ni(II) is disclosed, providing an extensive kinetic dataset. Rates span five orders of magnitude and exhibit strong ligand dependence, with monodentate ligands promoting transmetalation.

Genetic Risk and High Burden of Depression and Suicide in the Maya‐Mestizo Population of Yucatán, México

American Journal of Medical Genetics Part B: Neuropsychiatric Genetics, EarlyView.
ABSTRACT Major depression and suicide are critical public health concerns, particularly in underrepresented populations with unique genetic and sociocultural contexts. The Maya‐mestizo population presents the highest suicide rates in the country but remains understudied in psychiatric genetics. This study evaluated the association between three genetic

Australian Practitioners' Beliefs, Confidence, and Training Needs for Delivering Behaviour Support to Children and Young People in Out‐of‐Home Care

Australian Journal of Social Issues, EarlyView.
ABSTRACT Children in out‐of‐home care (OOHC) frequently present with complex behavioural needs. In New South Wales (NSW), behaviour support plans (BSPs) are mandated when restrictive practices, including psychotropic medication, are used. Little research has examined whether the statutory workforce is adequately prepared to meet behaviour support ...

A wavelet method for solving backward heat conduction problems

Electronic Journal of Differential Equations, 2017
In this article, we consider the backward heat conduction problem (BHCP). This classical problem is more severely ill-posed than some other problems, since the error of the data will be exponentially amplified at high frequency components.
