Deep Ritz - Finite element methods: Neural network methods trained with finite elements
Computer Methods in Applied Mechanics and EngineeringWhile much attention of neural network methods is devoted to high-dimensional PDE problems, in this work we consider methods designed to work for elliptic problems on domains $Ω\subset \mathbb{R} ^d, $ $d=1,2,3$ in association with more standard finite elements. We suggest to connect finite elements and neural network approximations through training, i.

International Journal of Mechanical System Dynamics, EarlyView.ABSTRACT Understanding the dynamic behavior of structural components is crucial for optimizing performance and ensuring structural integrity. This study presents a new method that combines a systematic experimental investigation of four distinct hole geometries (circular, square, compact rectangular, and long rectangular) with varying hole counts, all ...

Comparing energy levels in isotropic and anisotropic potentials
, 2015 Qualitative information about the quantized energy levels of a system can be of great value. We study the relationship between the bound-state energies of an anisotropic potential and those of its spherical average.

Righting Past Wrongs Through Restorative Justice: Managerial Motivations for Collaboration
Nonprofit Management and Leadership, EarlyView.ABSTRACT Nonprofits are crucial to state collaborations as their embedded nature in communities allows them to gain the trust necessary to facilitate change and enhance strengths. As nonprofits collaborate with the public sector to tackle systemic challenges, understanding managerial motivations for collaboration and implications for social change is ...

Comment on: 'A simple analytical expression for bound state energies for an attractive Gaussian confining potential' [PDF]
, 2012 We discuss a recently proposed analytical formula for the eigenvalues of the Gaussian well and compare it with the analytical expression provided by the variational method with the simplest trial function.

Higher-order multi-scale deep Ritz method for multi-scale problems of authentic composite materials
, 2023 The direct deep learning simulation for multi-scale problems remains a challenging issue. In this work, a novel higher-order multi-scale deep Ritz method (HOMS-DRM) is developed for thermal transfer equation of authentic composite materials with highly oscillatory and discontinuous coefficients. In this novel HOMS-DRM, higher-order multi-scale analysis

PLANTS, PEOPLE, PLANET, EarlyView.As climate change alters seasonal patterns, temperate tree populations face a growing risk of phenological mismatch, where seed dispersal and germination no longer align with favourable conditions for survival. This study predicted how warming by the end of the century will affect seed dormancy breaking and germination in populations of three UK tree ...

Environmental contaminants exposure and preterm birth: a systematic review [PDF]
, 2019 Preterm birth is an obstetric condition associated with a high risk of infant mortality and morbidities in both the neonatal period and later in life, which has also a significant public health impact because it carries an important societal economic ...
