Laser Remelting of a CrMnFeCoNi High‐Entropy Alloy: Effect of Energy Density on Elemental Segregation

Advanced Engineering Materials, EarlyView.
Laser remelting of a CrMnFeCoNi high‐entropy alloy reveals that optimal chemical homogenization occurs between 30 and 40 J·mm−2. Within this range, elemental segregation is reduced by over 30% compared to the as‐cast state. The study establishes this window as a fast, effective alternative to prolonged annealing for achieving uniform elemental ...

First SDO AIA Observations of a Global Coronal EUV "Wave": Multiple Components and "Ripples"

, 2012
We present the first SDO AIA observations of a global coronal EUV disturbance (so-called "EIT wave") revealed in unprecedented detail. The disturbance observed on 2010 April 8 exhibits two components: one diffuse pulse superimposed on which are multiple ...

Pulse transit time estimation of aortic pulse wave velocity and blood pressure using machine learning and simulated training data

PLoS Comput. Biol., 2019
Recent developments in cardiovascular modelling allow us to simulate blood flow in an entire human body. Such model can also be used to create databases of virtual subjects, with sizes limited only by computational resources. In this work, we study if it

Ferrocene Derivatives Enable Ultrasensitive Perovskite Photodetectors with Enhanced Reverse Bias Stability

Advanced Functional Materials, EarlyView.
Novel ferrocene derivatives (e.g., FcPhc2) are used as an ultrathin layer hole‐blocking layer, reducing hole injection from the Ag contact. This results in an ultralow noise spectral density of 1.2 × 10−14 A Hz−1/2, and a high specific detectivity of 8.1 × 1012 Jones at −0.5 V.

Validating tomographic model with broad-band waveform modelling: an example from the LA RISTRA transect in the southwestern United States [PDF]

, 2007
Traveltime tomographic models of the LA RISTRA transect produce excellent waveform fits if we amplify the damped images. We observe systematic waveform distortions across the western edge of the Great Plains from South American events, starting about 300

Determinants of Brachial-Ankle Pulse Wave Velocity and Carotid-Femoral Pulse Wave Velocity in Healthy Koreans

Journal of Korean Medical Science, 2014
The aim of this study was to determine the normal value of brachial-ankle pulse wave velocity (baPWV) and carotid-femoral pulse wave velocity (cfPWV) according to age group, gender, and the presence of cardiovascular risk factors in healthy Koreans, and to investigate the association between PWV and risk factors such as prehypertension, dyslipidemia ...

Optical Control of the Thermal Conductivity in BaTiO3

Advanced Functional Materials, EarlyView.
Light‐driven manipulation of thermal conductivity in archetypal ferroelectric, BaTiO3, offers a novel and effective approach for the dynamical control of the heat flux, with potential applications in thermal management and phonon‐based logic. Abstract Achieving dynamic control over thermal conductivity remains a formidable challenge in condensed matter
