Optoelectronic Synaptic Devices Using Molecular Telluride Phase‐Change Inks for Three‐Factor Learning

open access: yesAdvanced Functional Materials, EarlyView.
Optoelectronic synaptic devices based on solution‐processed molecular telluride GST‐225 phase‐change inks are demonstrated for three‐factor learning. A global optical signal broadcast through a silicon waveguide induces non‐volatile conductance updates exclusively in locally electrically flagged memristors.

Optical Signature of Moiré Superlattices Formed by Twisted SrTiO3 Membranes

open access: yesAdvanced Functional Materials, EarlyView.
We discover optical signatures from bonded interfaces in twisted SrTiO3 moiré superlattices, including low‐frequency Raman vibrational modes and strong second‐harmonic generation, consistent with strong interlayer coupling inferred from cross‐sectional electron microscopy and ab initio calculations. ABSTRACT Moiré superlattices formed at the interfaces

Determining the role of a small GTPase, Ral, and an endocytic factor, epsin, in Drosophila Notch signaling [PDF]

open access: yes, 2013
textCell-cell communication events are crucial to determine the fate of each cell during development. Notch signaling is involved in many different contexts in determining cell fate by mediating cell-cell communication.

Morphometric study of suprascapular notch

open access: yesNational Journal of Clinical Anatomy, 2013
Background and aims: Suprascapular nerve may be compressed anywhere along its course but most commonly at the level of SSN (suprascapular notch) and spinoglenoid notch.

Strong Lead‐Free Bioinspired Piezoceramics for Durable Energy Transducers

open access: yesAdvanced Functional Materials, EarlyView.
We fabricated brick‐and‐mortar lead‐free piezoceramics with Bi0.5Na0.5TiO3 monocrystal platelets as bricks and amorphous silica as mortar. The alignment of the bricks and the presence of the amorphous silica led to anisotropic residual stresses. These residual stresses increase the samples toughness, strength and durability while the brick alignment ...

Time-average cavitation characteristics in U-shaped notch hydraulic spool valve interpreted via effective flow area evolution

open access: yesEngineering Applications of Computational Fluid Mechanics
Cavitation-induced erosion is a critical challenge in U-shaped notch (USN) hydraulic spool valves. However, the coupled influence of notch depth and valve opening on cavitation morphology remains unclear.

Bioinspired Hydrogels with Broadly Programmable Mechanics for Soft‐Tissue Interfaces

open access: yesAdvanced Functional Materials, EarlyView.
Sea cucumber‐inspired gelatin hydrogels are formed by directional freezing and mechanically programmed through subsequent ionic treatment. Multiscale characterization and modeling link ion‐regulated chain interactions to directional load transfer within the aligned hierarchical architecture.

Advancing Human Skin Equivalents: The Crucial Role of Neurovascular Integration

open access: yesAdvanced Healthcare Materials, EarlyView.
This review discusses the importance of integrating vascular and peripheral nerve systems into human skin equivalents (HSEs) to better recapitulate native skin physiology. Recent advances in vascularized, innervated, and neurovascularized HSEs are highlighted, together with emerging bioengineering strategies, current challenges, and future ...

A crack-like notch analogue for a safe-life fretting fatigue design methodology

open access: yes, 2003
Various analogies have recently been proposed for comparing the stress fields induced in fretting fatigue contact situations, with those of a crack and a sharp or a rounded notch, resulting in a degree of uncertainty over which model is most appropriate ...

On the potential in a strip with a pair of 𝑈 notches [PDF]

open access: yesQuarterly of Applied Mathematics, 1985
In \({\mathbb{R}}^ 2\), consider the strip \(y=0\), \(y=2a\) with a pair of U notches. The upper U notch is of the same size as the lower one and located symmetrically with respect to the line \(y=a\). The paper deals with the problem of finding a function in \({\mathbb{R}}^ 2\) which gives potential on the lower boundary as 1 and that on the upper ...
