Controlled and Reversible Photomodulation of the Alkoxy Azobenzene Monolayer: Combined Experimental and Molecular Dynamics Simulation Study

Abstract Constant-area photoswitching of Langmuir monolayer films of an alkoxy azobenzene (AAB) molecule was carried out at different phases of the monolayer, and the effect on surface pressure change was studied. The surface pressure rise upon UV light irradiation was found to d...

ECONOMIC ANALYSIS OF THE SERVICE SECTOR IN INDIA AND CHINA (1990-2025): STRUCTURAL TRANSFORMATION, FACTOR PRODUCTIVITY, AND SUB-SECTORAL PERFORMANCE GAPS

This study provides comparative analysis of the economic performance, structural transformation, and factor productivity of the service sectors in India and China from 1990 to 2025. In 1990, both nations possessed tertiary sectors of virtually identical output scale: India genera...

Quantizability of Lorentz-violating field theories with singular Hamiltonians

Spontaneous Lorentz-violating models of an antisymmetric tensor field are known to possess a singular Hamiltonian on the vacuum manifold, leading to unresolvable pathologies that render such theories unfit for cosmological studies. In this work, we introduce an auxiliary vector f...

Estimation and optimal design for constant stress model under maximum ranked set sampling with unequal samples

This paper develops an optimal design for a constant stress model under Maximum Ranked Set Sampling with Unequal Samples (MaxRSSU) which is a novel approach to improve estimation efficiency in life test studies. The maximum likelihood and Bayesian methods are used to estimate mod...

Optoelectronic‐Driven Multi‐Functional MoS 2 :PVA Flexible Memristor for In‐Sensor Neuromorphic Computing

ABSTRACT This article presents a multifunctional Ag/MoS 2 :PVA/SnO 2 /Pt memristive device that demonstrates resistive memory, synaptic learning, and optical information processing. The device exhibited stable bipolar resistive switching with low operating voltages with SET and R...

Situating abortion: Hindi cinema and the cultural politics of reproductive choice

After gaining independence in 1947, India witnessed a high maternal mortality rate due to unsafe and illegal abortions. As a result, the nation introduced the Medical Termination of Pregnancy Act in 1971, based on the British statute. Despite its progressive provisions, this Act...

Copper-Catalyzed Regioselective Synthesis of Fluorescent Indazolo[2,3- a ]quinazolines and Their Photophysical Studies

Abstract A regioselective copper-catalyzed one-pot cyclization of 3-aminoindazoles with 2-bromobenzyl bromides has been developed under ligand-free conditions for the efficient synthesis of indazolo[2,3-a]quinazolines. This reaction proceeds through initial site-selective nucleop...

Optimization of coal blending in thermal power plants using G ray‐ T aguchi method: An operations management perspective

Abstract Coal quality variability significantly affects the efficiency, operating cost, and environmental performance of coal‐fired thermal power plants. This study aims to optimize coal blending by integrating the Taguchi Design of Experiments (DOE) with Gray Relational Analysis...

Towards sustainable public transit: development of representative driving cycles for electric and CNG buses using naturalistic micro-trip data from Patna, India

Abstract With the increasing emphasis on sustainable urban mobility, electric buses are rapidly being integrated into public transportation networks in Indian cities. A critical component in evaluating their energy consumption and operational efficiency is the development of repr...

Probing Salt‐Induced Changes in the Self‐Assembly Behavior of Gemini Surfactants Using Scattering and Spectroscopic Techniques

This study investigates how Gemini surfactants (GSs) with varying alkyl chain lengths and spacer architectures regulate interfacial behavior, self‐assembly, and the photophysical response of Merocyanine 540 (MC540) in aqueous media. Tensiometric measurements demonstrate that incr...

Assessment of Steel Slag and Rubber-Coated Aggregate as Ballast Based on Model Track Tests

Abstract A series of model track tests were conducted to investigate the effect of loading frequency ( f ) on the deformation and degradation characteristics of unreinforced and geogrid-reinforced steel-slag ballast (SSB) and rubber-coated ballast (RCB) under clean and coal-foule...

Adaptive multi-scale attention-enhanced V-NET for accurate and efficient multi-shell diffusion MRI estimation

Multi-shell acquisition protocols sample diffusion signals at different b -values. While higher b -values (e.g., \(b = 2000\, \mathrm {s/mm^2}\) ) offer increased sensitivity to microstructural features, their acquisition is time-intensive and suffers from reduced signal-to-noise...

Cyclic behavior of clayey lumps intruded quaternary alluvial sand in the Indo-Gangetic Plain: an experimental assessment

The dynamic behaviour of soils under cyclic loading is a key concern in geotechnical engineering, particularly in seismic-prone regions. The Middle Ganga Plain is characterised by unique geomorphological features, containing collapsible cohesive alluvial lumps that naturally form...

Analysing Urban Environmental Dynamics through Multi-Sensor Remote Sensing and Deep Learning: An Integrated Classification-Regression Framework

Urban centers worldwide are facing changes in terms of environmental standards and an increase in temperatures.Recent significant developments, particularly in developing nations, have led to an increase in Land Surface Temperature (LST) and surface thermal variations in urban ar...
