Design of a Highly Linear Voltage Differencing Transconductance Amplifier Using Source Degeneration

This paper presents a highly linear voltage differencing transconductance amplifier (VDTA) utilizing a source degeneration technique to enhance input linearity while maintaining wide bandwidth. The incorporation of source degeneration within both transconductance stages of the pr...

Filling the Shadow: A Propositional Model of Gravastar Accretion in f ( R , L m , T ) Gravity

While General Relativity remains our most rigorously tested framework for gravitation, the theoretical persistence of singularities within standard black hole solutions continues to motivate the exploration of mathematically regular alternatives. Gravitational vacuum stars (grava...

Data-Driven Modeling and Circuit-Aware Optimization of Gate-All-Around Multi-Bridge Channel FETs

Aggressive semiconductor scaling toward sub-3 nm technology nodes requires advanced device optimization frameworks capable of efficiently exploring high-dimensional electrostatic design spaces while preserving physics accuracy and circuit-level applicability. Conventional Technol...

Optimize the least required quantity of decoupling capacitors in PDN design

A least required quantity (LRQ) calculation of each decoupling capacitor (decap), considering power distribution network (PDN) lumped circuit model parameters is presented in this passage. The proposed method uses equivalent impedance which contains the impedance of Voltage Regul...

A Multi-Chip Cascadable MIC6_V4 ASIC for the NICA-MPD Inner Tracking System

To meet the upgrade requirements for the Inner Tracking System (ITS) of the Multi-Purpose Detector (MPD) at the Nuclotron-based Ion Collider facility (NICA) for extremely high spatial resolution and low material budget, we present a monolithic active pixel sensor array chip, MIC6...

Production of 135 I and 135 Xe through proton induced fission of 238 U

Yields of fission fragments [Formula: see text]I and [Formula: see text]Xe populated by proton induced fission of [Formula: see text]U have been measured using stacked foil activation technique. In the yield of [Formula: see text]I and [Formula: see text]Xe, in addition to the di...

On The Nonexistence Of Good Involutions On Symplectic Quandles

We investigate a necessary and sufficient condition for the existence of good involutions on symplectic quandles, which are defined on free R-modules equipped with an antisymmetric bilinear form. In particular, we discuss the nonexistence of such good involutions under various al...

Wreath products and cascaded FSRs

We show that the transition function of the cascaded connection of two FSRs can be viewed as an element of an imprimitive wreath product. This allows us to study periods of cascaded connections with algebraic methods, obtaining both a general, nontrivial upper bound on the maximu...

Cartan Horadam Spinors

Number sequences with wide-ranging applications in mathematics, physics, medicine, and engineering remain an active research topic. This study examines these sequences through the general framework of Horadam numbers and their special cases associated with Cartan numbers. By defi...

Design and Vibration Reduction Performance of Chiral Metamaterial Vibration-Damping Structure for High-Speed Train Floors

To address the insufficient low-frequency vibration reduction capability of high-speed train floor structures, a chiral metamaterial structure was proposed and fabricated as a substitute for wooden supports. The structure consists of an aluminum chiral load-bearing frame and an a...

Taxonomy-Constrained Semantic Alignment For Large-Scale Recruitment Data Structuring

Large-scale recruitment data have emerged as a valuable source for studying labor demand, educational planning, and regional talent dynamics. However, the analytical value of such data hinges on the ability to transform raw job postings into stable, structured records that are su...

Obesity is more strongly associated with physical performance and body composition than sarcopenia in patients with spondyloarthritis

Abstract Objectives Integrated data on body composition, objective physical performance and daily physical activity are limited in spondyloarthritis (SpA). The objective of this study is to describe DXA-derived body composition phenotypes and examine their cross-sectional associa...

Formalization and Verification of the Message Delivery Mechanism in Apache Pulsar

Apache Pulsar is a cloud-native, high-performance, and scalable distributed Message-Oriented Middleware (MOM) widely used for processing large-scale real-time data streams. Due to its distributed architecture and multi-tenancy features, Pulsar excels in high-throughput and low-la...

Topological Sector of Generalized Pre-geometric Gravity

We investigate the topological sector of pre-geometric gravity formulated as a constrained BF gauge theory. Starting from the Generalized Wilczek Gravity – a theory where spacetime emerges from spontaneous symmetry breaking of a (anti)de Sitter gauge group – we demonstrate that t...

Solutions To Some Open Problems In Matrix Analysis

We solve a problem posed by Audenaert and Kittaneh in 2012 by proving that the Aujla–Bourin subadditivity inequality can be strengthened to an optimal form. We also answer questions posed by Bourin and the second author: (1) we significantly extend both the reciprocal Lie–Trotter...

Variance-Refined In-Diameter Lower Bound for the First Dirichlet Eigenvalue

A Sensitivity Interface between Dark-Matter Perturbations and Pycnonuclear Burning in Ultramassive White Dwarfs

Pycnonuclear burning in ultramassive white dwarfs is governed by quantum tunneling and is therefore unusually sensitive to small changes in the dense stellar environment. Rather than asking whether dark matter immediately explains a cooling anomaly, we address a more controlled q...
