Effect of Deformation Speed on Stress Corrosion and Fracture Toughness of Extruded Mg10Dy and Mg10Dy1Nd Using C-Ring Tests

The influence of the deformation speed in C-ring tests in Ringer's solution on crack initiation and propagation of extruded Mg10Dy and Mg10Dy1Nd is investigated. Deformation speeds varying from 2 to 0.012 mm/min allow corrosion times from a few minutes to hours. Both the crack initiation force (higher for Mg10Dy1Nd) and displacement (higher for Mg10Dy) increase with decreasing deformation speed up

Influence of Corrosion Extent on Residual Tensile Strength and Corrosion Fatigue Properties of an Mg-Y-Nd Alloy Characterized by μCT

This study focuses on the influence of inhomogeneous corrosion on the quasi-static and cyclic properties of an Mg−Y−Nd alloy. Uniform corrosion is essential for biodegradable implant materials to avoid notching effects and premature failure. Previous studies on extruded Mg−3Y−3RE have shown a pitting tendency in Ringer’s solution at 37 °C. Tensile tests on pre-corroded samples with different corro

On Rotational Waves of Limit Amplitude

In this note we discuss some recent results on extreme steady waves under gravity. They include the existence and regularity theorems for highest waves on finite depth with and without vorticity. Furthermore, we state new results concerning the asymptotic behavior of surface profiles near stagnation points. In particular, we find that the wave profile of an extreme wave is concave near each crest,

Non-local transitions and ground state switching in the self-organization of vascular networks

The model by D. Hu and D. Cai [Phys. Rev. Lett. 111, 138701 (2013). doi:10.1103/PhysRevLett.111.138701] describes the self-organization of vascular networks for transport of fluids from source to sinks. Diameters, and thereby, conductances, of vessel segments evolve so as to minimize a cost functional E . The cost is the trade-off between the power required for pumping the fluid and the energy con

Association between the EAT-Lancet Diet, Incidence of Cardiovascular Events, and All-cause Mortality : Results from a Swiss Cohort

BACKGROUND: An unhealthy diet is a major contributor to several noncommunicable diseases, including cardiovascular diseases (CVD), the leading cause of death worldwide. Additionally, our food system has significant impacts on the environment. The EAT-Lancet Commission has recommended a healthy diet that preserves global environmental resources.OBJECTIVE: This prospective study evaluated the associ

Improving neural network efficiency with multifidelity and dimensionality reduction techniques

Design problems in aerospace engineering often require numerous evaluations of expensive-to-evaluate high-fidelity models, resulting in prohibitive computational costs. One way to address the computational cost is through building surrogates, such as deep neural networks (DNNs). However, DNNs may only be an effective surrogate when sufficient evaluations of the high-fidelity model are required suc

Identifying Enablers for a Circular Healthcare Supply Chain : An Integrated Fuzzy DEMATEL-MMDE Approach with Hesitant Information

Over the past decade, the healthcare industries have been facing the issue of resource scarcity due to socio-political wars, the COVID-19 pandemic, the luxury lifestyles of people, and the prevalence of single-use medical devices. The circular economy (CE) can be vital in accommodating the evolving patient and provider demands. The CE defies the conventional take-make-dispose process and advocates

Strong diagnostic performance of plasma ptau217 for CSF biomarker-defined young-onset Alzheimer disease in a diagnostically heterogeneous clinical cohort

Objective: We investigated diagnostic utility of phosphorylated tau 217 and 181 (ptau217, ptau181), glial fibrillary acidic protein (GFAP), amyloid beta 42 and 40 (Aβ42, Aβ40), and neurofilament light (NfL) to distinguish biomarker-defined Alzheimer disease (AD) from non-AD conditions, in a heterogenous clinical cohort of younger people. Methods: Plasma biomarkers were analysed using ultrasensitiv

Minority joy, minority growth, and minority peace : Transgender and gender diverse people’s varied positive lived experiences

Background: Compared to negative experiences and ill health, little attention has been paidto positive experiences connected to being transgender and gender diverse (TGD).Aim: The aim of the current study was to explore TGD people’s positive experiences in depth.Methods: In total, 33 TGD people were interviewed. Transcripts were analyzed using reflexivethematic analysis.Results: Results show that

Cryogenic Evaluation of Resistive Random Access Memory With Enhanced Endurance at 14 K

The nonvolatile cryogenic memories can play an important role in realizing energy-efficient and scalable low-temperature electronics for quantum computing and future high-performance computing systems. In this article, we evaluate he cryogenic performance of HfOx-based resistive random access memory (RRAM) and demonstrate that the addition of extremely thin ∼0.5-nm AlOx barrier layers enables a h
