Close-in companions to contact binary stars
, 2014 W UMa-type contact binaries are composed of two late-type main-sequence stars, where both components are filling their critical Roche Lobes and sharing a common convective envelope.

Memristive‐Gated RC‐Delay Synaptic Transistors for Time‐Encoded Analog in‐Memory Computing
Advanced Functional Materials, EarlyView.A Memristive‐Gated Transistor for Time‐Encoded Analog In‐Memory Computing — By exploiting the RC delay of a self‐rectifying interface‐type memristor, nonlinear I–V distortion is structurally bypassed, enabling 3‐bit nonvolatile memory, spike‐timing‐based analog encoding, and hardware‐calibrated reservoir‐computing validation within a unified device ...

The structure equations of contact binaries [PDF]
Astronomy & Astrophysics, 2002 The structure equations of contact binaries are discussed. An equation for the transfer of mass between the com- ponents is derived. Serious uncertainties concern only the transfer of energy. They are expressed as unknown functions. An evolution code for contact binaries is presented.

Electrically Induced Phase Transition and Synaptic Functionality in MoTe2/Graphene Memristors
Advanced Functional Materials, EarlyView.An electrically induced reversible 2H ↔ 1T′ phase transition is demonstrated in a vertical Au/Ti/MoTe2/graphene memristor with a laterally contacted graphene electrode. Resistive switching proceeds through a compositionally invariant amorphous/2H ↔ amorphous/1T′ transformation, in which a self‐formed amorphous MoTe2 interfacial region is proposed to ...

Using MESA to Test Our Theory of Contact Binary Star Evolution [PDF]
, 2021 A contact binary star system consists of two stars orbiting each other so closely that they share a common atmosphere. Nearly 1% of stars like our sun are contact binaries, yet there is not a comprehensive model of their lives.

An Adaptive Inhibitory WSe2 Transistor for Retinomorphic In‐Sensor Image Processing
Advanced Functional Materials, EarlyView.Conventional retinomorphic devices typically require deliberate gate‐bias tuning for each illumination condition. In this paper, we demonstrate an adaptive inhibitory WSe2 transistor that uses photo‐induced regime shift between the subthreshold and accumulation modes to achieve decision‐free, intensity‐adaptive image processing within a single pixel ...

Orbital Modulation Induced by a Third Component in the Overcontact Binary V0554 Dra
The Astrophysical JournalWe present the first comprehensive photometric and spectroscopic analysis of the overcontact eclipsing binary V0554 Dra. By simultaneously modeling multiband light curves and radial velocity data using the Wilson–Devinney code, we determine that the ...
