World's first micromachine twists 2D materials at will

Phys.org 

Just a few years ago, researchers discovered that changing the angle between two layers of graphene, an atom-thick sheet of carbon, also changed the material's electronic and optical properties. They then learned that a "twist" of 1.1 degrees—dubbed the "magic" angle—could transform this metallic material into an insulator or a superconductor, a finding that ignited excitement about a possible pathway to new quantum technologies.

Mata House / Estúdio Mariana Vilela + Atelier Daniel Florez

Archdaily.com 

Casa Na Mata is a project in which the domestic space and wild nature its intentionally dissolved in order to remain hidden and invisible. Located in a forest area with a high density of Mata Atlantica, in Praia de Pipa, Brazil, the house volume it’s the result of the ecological intention of generating a footprint by occupying the vacant tree areas of the plot with a result of a “U” shape volume around a tropical central courtyard with trees.

Accelerating automatic model finding with layer replications case study of MobileNetV2

Plos.org 

by Kritpawit Soongswang, Chantana Chantrapornchai

In this paper, we propose a method to reduce the model architecture searching time. We consider MobileNetV2 for 3D face recognition tasks as a case study and introducing the layer replication to enhance accuracy. For a given network, various layers can be replicated, and effective replication can yield better accuracy. Our proposed algorithm identifies the optimal layer replication configuration for the model. We considered two acceleration methods... Читать дальше...

The impact of sociocultural contexts on the knowledge, attitudes, and practices of adults living with HIV/AIDS in Ethiopia towards metabolic syndrome risks: A descriptive phenomenology study using the PEN-3 model

Plos.org 

by Girma Tenkolu Bune

Introduction

The global HIV/AIDS initiative in Africa aims for eradication by 2030 and treatment for 95% of HIV-positive adults by 2025. Adult People living with HIV (PLWHs) face health complications, including metabolic syndrome (MS), which heightens the risk of non-communicable diseases (NCDs) and cardiovascular problems. WHO and UNAIDS advocate for the integration of NCDs into primary healthcare, yet addressing MS remains a significant challenge in Africa. The WHO’s... Читать дальше...

Latent burnout profile analysis in hospital doctors in Ireland

Plos.org 

by Gordon Haire, Lucia Prihodova, Sophia Kilcullen, Blánaid Hayes

Background

Burnout, characterised by emotional exhaustion (EE), depersonalisation (DP) and reduced personal accomplishment (PA), is caused by chronic workplace stress. Though widely reported in doctors, variability in definitions and assessment methods render comparisons between studies challenging. Furthermore, traditional methods of reporting burnout can be misleading, focusing more on individuals than on the workplace. Читать дальше...

Experimental study of laser scattering protection system for low-speed aircraft

Plos.org 

by Elliott Donghyun Kim, Gisu Park

This study introduces a laser scattering system to protect a low-speed aircraft. Scattering was selected to reduce the laser’s intensity targeting the sensor of an aircraft and simultaneously maintaining the functionality of aircraft optics. Mie scattering, known for effectively decreasing short-wave infrared light, was employed by utilizing water aerosols having a diameter of 1 to 5 μm. Experimental results regarding the decrease of the laser intensity... Читать дальше...
