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 ...

A Wave–Particle Model of Energy Transfer Between Two Atoms in a Transactional Interpretation of Quantum Mechanics

Entropy
In 2000, Carver Mead introduced a time-symmetrical theory of energy exchange between two atoms, building on the Transactional Interpretation of Quantum Mechanics by John Cramer in 1986.

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 ...

Accelerated Discovery of Topological Spin Phase Diagrams in CrSBr Magnets Via High‐Throughput Optimization

Advanced Functional Materials, EarlyView.
Here, we develop a high‐throughput algorithm that accelerates the elucidation of phase diagrams of topological spin textures using limited computational resources at high numerical accuracy. Applying this framework to the van der Waals magnet CrSBr, we unveiled a hierarchy of previously unknown topological textures (domain‐wall bimerons, bimeron chains,

Treating Alzheimer's and Neuroregeneration Vía Quantum State Restoration (Reviving the Dead Brain) Using the Properties of Quantum Intelligence

Natural Sciences
In the Orch OR model, information is stored in a quantum form by the arrangement of electrons or the type of polarization and rotation of electrons, or the movement of photons and their exchange between hexagonal structures or other molecular structures ...

Deep Learning and Metaheuristic Approaches for Financial Risk Prediction in Digital Economy

Journal of Engineering, Project, and Production Management
Predicting financial risk has become increasingly important as digital-economy firms generate highly volatile and complex data. Existing Deep-Learning (DL) models struggle with high-dimensional inputs, unstable optimization, and limited generalization ...

Non-relativistic Quantum Mechanics [PDF]

, 2006
This essay is a discussion of the philosophical and foundational issues that arise in non-relativistic quantum theory. After introducing the formalism of the theory, I consider: characterizations of the quantum formalism, empirical content, uncertainty ...

Sub‐1 ms Optoelectronic Synapse Based on {ZnCdO/ZnO} Multilayer Structure for High‐Speed Neuromorphic Vision Systems

Advanced Functional Materials, EarlyView.
Eu‐doped {ZnCdO/ZnO} structures grown on Si are developed, showcasing dual‐functionality controlled by europium doping. While high europium concentration transforms the device into an ultrafast, self‐powered photodetector, low‐doped structures can be used as an optoelectronic synapse.

Circularly Polarized Electroluminescence and Spin‐Polarized Carrier Transport in Chiral‐Doped Polymer Films

Advanced Functional Materials, EarlyView.
Chiral dopants induce supramolecular chirality in an achiral polymer (PFO), generating spin‐polarized carriers via the chiral‐induced spin selectivity (CISS) and suggesting a possible contribution of Spin‐polarized carrier transport to circularly polarized electroluminescence (CPEL).
