Minimal hypersurfaces and bordism of positive scalar curvature metrics [PDF]

open access: yesarXiv, 2016
Let $(Y,g)$ be a compact Riemannian manifold of positive scalar curvature (psc). It is well-known, due to Schoen-Yau, that any closed stable minimal hypersurface of $Y$ also admits a psc-metric. We establish an analogous result for stable minimal hypersurfaces with free boundary.

A Multimodal Humidity Adaptive Optical Neuron Based on a MoWS2/VOx Heterojunction for Vision and Respiratory Functions

open access: yesAdvanced Materials, EarlyView.
A multifunctional memristor is demonstrated for in‐memory sensing and computing, leveraging a MoWS₂/VOx heterojunction to enable high ON/OFF ratio up to 10⁸ with ultralow operating voltages of ±0.2 V. This bio‐inspired multimodal design exhibits tunable synaptic behavior across electrical, optical, and humidity stimuli, enabling in situ modulation of ...

Optimal Design of Thin-film Plasmonic Solar Cells using Differential Evolution Optimization Algorithms [PDF]

open access: yesarXiv, 2018
An approach using a differential evolution (DE) optimization algorithm is proposed to optimize design parameters for improving the optical absorption efficiency of plasmonic solar cells (PSC). This approach is based on formulating the parameters extraction as a search and optimization process in order to maximize the optical absorption in the PSC ...

Buried Interface Regulation with a Supramolecular Assembled Template Enables High‐Performance Perovskite Solar Cells for Minimizing the VOC Deficit

open access: yesAdvanced Materials, EarlyView.
Self‐assembled amphiphilic phosphonate‐based supramolecule functions as a perovskite crystallization‐driven template at SnO2/perovskite buried interface, which induces a highly preferred (100) orientation toward out‐of‐plane direction, facilitates carrier extraction and transfer, passivates the intrinsic defects, and achieves a promising efficiency of ...

The characteristics of pediatric ulcerative colitis with primary sclerosing cholangitis: A single-center study in Taiwan

open access: yesPediatrics and Neonatology, 2021
Background: Primary sclerosing cholangitis (PSC) is often associated with ulcerative colitis (UC). We investigated the clinical characteristics of pediatric UC patients with and without PSC.

X Her and TX Psc: Two cases of ISM interaction with stellar winds observed by Herschel

open access: yes, 2011
The asymptotic giant branch (AGB) stars X Her and TX Psc have been imaged at 70 and 160 microns with the PACS instrument onboard the Herschel satellite, as part of the large MESS (Mass loss of Evolved StarS) Guaranteed Time Key Program. The images reveal
