Competing hysteresis mechanisms in HZO/MoS2 transistors with a metal–ferroelectric–metal–insulator–semiconductor gate stack

Ferroelectric field-effect transistors based on hafnium oxide offer a versatile platform for advanced memory concepts. Here, we demonstrate a proof-of-concept top-gated Hf0.5Zr0.5O2-based transistor integrating a metal–ferroelectric–metal–insulator–semiconductor (MFMIS) gate stac...

Application of Machine Learning Methods for Processing and Analyzing Data from Probe and Optical Microscopy of Biological Objects

Abstract This review systematizes modern machine learning (ML) methods for solving key image processing tasks in optical microscopy (OM) and atomic force microscopy (AFM). Traditional microscopy data analysis methods face problems of subjectivity, low throughput, and difficulty i...

Thermodynamic Drivers of Rapid Transition From Drought to Flood in Siberia, Russia

Abstract Siberia is a warming hotspot under the impact of climate change, and faces growing threats from hydroclimatic extremes. The rapid transition from drought to extreme wet conditions (hereafter RTDFs) could exacerbate compound hazards, as intense rainfall on drought‐weakene...

Microstructural design of interconnected Cu@Ni core-shell nanowire-based networks as high-performance electrodes for supercapacitors

Copper nanowires (CuNWs) are highly attractive for electrochemical energy storage devices due to their high electrical conductivity and commercial accessibility; however, their susceptibility to oxidation remains a significant challenge. In this study, ultralong copper and Cu@Ni...

Development of a Highly Efficient System for the Production of the Holoform of Recombinant Cytoglobin

Abstract Objective: A highly efficient production system for recombinant human cytoglobin using minimal medium has been developed and optimized. This system enables the production of the water-soluble holoform of the protein—in both unlabeled and isotopically labeled forms—in qua...

Molecular mechanism of calcium inhibition in viral channelrhodopsins

Abstract Viral channelrhodopsins (VCR1s) are giant-virus-encoded light-gated channels permeable to monovalent and divalent cations, including Na + and Ca 2+ ions, and inhibited by millimolar Ca 2+ concentrations. Here, we combine X-ray crystallography, time-resolved UV-vis spectr...

Structure of 𝒩 = 2 superfield higher-spin abelian cubic interactions

A bstract In this article we study the structure of the 𝒩 = 2 abelian higher-spin cubic ( s 1 , s 2 , s 2 ) vertices and the corresponding 𝒩 = 2 higher-spin supercurrents, introduced in arXiv:2408.00668 . These interactions are possible only for s 1 ≥ 2 s 2 . Conserved supercurre...

Biopesticidal Potential of the Cannabis sativa L. Metabolites: A Denoised, Docking-Informed QSAR Model

Plant metabolites are a promising source of new biopesticides, but their chemical diversity exceeds the capacity of experimental screening. Cannabis sativa is a particularly attractive crop for discovering such compounds, although its metabolome has not been systematically evalua...

Exploring baryon semileptonic decays through polarization and entanglement

Abstract The unitarity of the Cabibbo–Kobayashi–Maskawa (CKM) matrix is a cornerstone of the standard model (SM). Precise tests of this unitarity require independent determinations of its elements, such as | V us |, which governs the transition between strange and up quarks. Curr...

Non-Hermitian trapping of Dirac exciton-polariton condensates in a perovskite metasurface

Massless Dirac particles avoid trapping because of their exceptional tunneling properties manifested in the so-called Klein paradox. This conclusion stems from the conservative treatment, but so far, it has not been extended to a non-Hermitian framework. Recently, driven-dissipat...

Yang–Baxter symmetries of type II supergravity

Abstract We provide a complete proof that Yang–Baxter bi-vector deformations are solution generating transformations in Type II supergravity. The proof does not rely on the assumption that the vielbein is invariant under Lie derivative along all Killing vectors entering the bi-ve...

Frequency control of superconducting resonators using integrated interferometers

Predictable frequency trimming of superconducting resonators at liquid-helium temperatures requires a tuning element whose usable range remains well defined despite screening currents and hysteresis. Here, we realize flux-controlled λ/4 coplanar-waveguide resonators terminated by...

Probing structural symmetry breaking in TMDC alloy via terahertz emission

We report on terahertz (THz) emission from bulk Mo0.5W0.5Se2 alloy surfaces, which exhibit a mechanism fundamentally distinct from that of their pristine transition metal dichalcogenide (TMDC) constituents. Systematic measurements of THz emission as a function of pump fluence, po...

Negative Spectrum of Non-local Operators with Periodic Potential

The paper deals with spectral analysis of non-local operators arising in population dynamics models. We consider negative periodic perturbations of non-local operators of the convolution type. Such operators describe evolutions of the first correlation function in the stochastic...

Multiple spiking functionalities in annealing-optimized Ag/Hf0.5Zr0.5O2-based memristive neurons

Rapid progress of artificial neural network applications in recent years has led to the issue of unprecedented energy consumption. It can be solved by the implementation of energy-efficient hardware based on non-von Neumann architectures, which requires the development of electro...

From volatile to nonvolatile resistive switching in a ferroelectric second-order memristor

Ferroelectric memristors are promising candidates for neuromorphic computing, yet their practical application is hindered by the trade-off between the volatile synaptic plasticity required for learning and the nonvolatile retention needed for long-term data storage. Here, we demo...

Conformal blocks of Wess-Zumino-Witten model from its free-field representation

A bstract A powerful approach to the celebrated Wess-Zumino-Witten (WZW) model is provided by its free-field realization. However, explicit calculations of conformal blocks are not described in the literature in full detail. We begin this study with the simplest cases of the $$ \...
