Combined grain refining and modification of conventional and rheo-cast A356 Al–Si alloy

open access: yes, 2006
This paper describes a comprehensive study on the combined addition of Ti-B grain refiner and Sr modifier elements to A356 Al-Si alloy. Using different qualitative and quantitative techniques in conventional and semi-solid metal castings, it is shown ...

Sustainable Hydrogel‐Forming Microneedle‐Reservoir Patches for Transdermal Delivery of Hydrophilic Macromolecules: Biopolymers, Green Manufacturing and Translation

open access: yesAdvanced Science, EarlyView.
Hydrogel‐forming microneedle (HFMN)‐reservoir patches provide a modular route for controlled transdermal delivery of hydrophilic biomacromolecules. The platform integrates skin‐barrier penetration, sustainable biopolymers, scalable green manufacturing, hydration‐driven transport, model‐cargo validation, and translational quality requirements.

Quantitative regional curvature analysis: Validation in animals of a method for assessing regional ventricular remodelling in ischemic heart disease [PDF]

open access: yes, 1991
Recent studies show the impact of left ventricular shape and remodelling on patient prognosis. This mandates the development of quantitative methods for measuring shape. Quantitative regional curvature analysis (QRCA) was developed to quantitate shape on

Machine Learning-Aided Property Prediction of Hybrid Organic–Inorganic Perovskites Using Hirshfeld Surface Representations of Crystal Structures

open access: yes, 2023
This paper describes a lightweight neural network (NN) to predict thermodynamic, electric, and electronic properties of hybrid organic–inorganic perovskites (HOIPs) using Hirshfeld surfaces as novel material representation for HOIPs.

Arhgef1 Deletion Disrupts Early Cortical Neurogenesis via PAK1 Overactivation and Causes Motor Dysfunction in Adulthood

open access: yesAdvanced Science, EarlyView.
ARHGEF1 plays a pivotal role in both embryonic cortical neurogenesis and adult motor function. During early development, it governs genesis of deep‐layer cortical neurons by negatively regulating RAC1/CDC42‐PAK1‐Cofilin signaling. In adulthood, ARHGEF1 is important for the maintenance of neuronal morphology and activity in the motor cortex, ensuring ...

An Infusible Decellularized Extracellular Matrix Material Binds to Vasculature in Infarcted Myocardium and Induces Pro‐Reparative Gene Expression Following Acute Myocardial Infarction Through Inherent Avidity and Bioactive Signaling

open access: yesAdvanced Science, EarlyView.
To better characterize an infusible extracellular matrix (iECM) material, we applied size‐based fractionation to separate out components into two major fractions. We characterized these fractions to understand how material properties such as composition, morphology, and biochemical properties affect bioactive effects in the context of acute myocardial ...

Midsagittal Cranial Shape Variation in the Genus Homo by Geometric Morphometrics [PDF]

open access: yes, 2004
Midsagittal profiles of crania referred to different taxa of the genus Homo have been analyzed by geometric morphometric techniques. Comparisons between single specimens using the thin-plate-spline function suggest a generalized reduction of the lower ...

Binary globular clusters

open access: yesNew Astronomy, 2000
The dynamics of a close binary system of globular clusters is considered. It is shown that the star transfer process from one of the components to the other should lead to the decrease of dimension of the first cluster with simultaneous increase of the dimension of the second cluster.
