Suicide Attempt by Swallowing Sponge or Pica Disorder: A Case Report

open access: yesActa Medica, 2011
Introduction: There are many ways how children with mental illness have actually tried to hurt themselves. Suicidal thinking or attempts always indicate that professional help is needed (2). Every object which can be potential dangerous should be removed

Geometry‐Based Neural‐Network Prediction of Electron Localization Function Topology in Dense Hydrogen

open access: yesChemistry – A European Journal, EarlyView.
We present a machine‐learning framework that predicts the electron localization function (ELF) of dense hydrogen directly from atomic geometry, bypassing explicit electronic‐structure calculations. Trained on ab initio data for fluid hydrogen across multiple pressures, the model achieves high accuracy and reveals pressure‐dependent nonlocal ...

Investigating the Cytoskeleton of DRGs Using Cryo‐Electron Microscopy and Deep Learning

open access: yesCytoskeleton, EarlyView.
ABSTRACT We describe a method for determining the ultrastructural organization of axons and varicosities of cultured dorsal root ganglion (DRG) neurons using cryogenic electron microscopy (cryo‐EM). Cryo‐EM reveals the dimensions, proximity, and overall organization of biological specimens in a near‐native state, avoiding artifacts of fixation and ...

Effect of Sequential and Combined Space‐Based Stressors on Perovskite Solar Cell Stability

open access: yesEcoEnergy, EarlyView.
A correlation between loss in performance and mobile ion concentration has been established by sequential stressing of perovskite solar cells under Low Earth Orbit conditions with exposure to protons, light, and thermal cycling. It is shown that the loss in performance increases when ion concentration increases and vice versa.

Data-driven transfer learning across MOF-derived zirconia polymorphs

open access: yesnpj Computational Materials
Despite extensive investigation of metal-organic framework (MOF) derived materials over the last 20 years, no systematic approach to predict the structural properties of the derived metal oxides is available. We present an integrated machine learning (ML)

Beyond Integer Charge Transfer: A New Design Rule Linking Dopant Strength and Counterion Separation to Efficient Carrier Transport in Conjugated Polymers

open access: yesSmall, EarlyView.
In this Research Article, the authors introduce a new design principle for doped conjugated polymers, showing that dopant energy depth relative to the host polymer (ΔE) can be leveraged to minimize Coulomb interactions and boost conductivity. This discovery offers a new and simple strategy to optimize the performance of organic electronics for everyday
