{Simulation is used to demonstrate a significant improvement in the quality of highly reliable and sophisticated products using accelerated life testing. We have discussed the estimation of unknown parameters using classical and Bayesian estimation methods for the generalized inv...

Prevalence and socio cultural determinants of childhood adversity in India and its implications for health outcomes

Adverse childhood experiences (ACEs) are recognized as a major public health concern due to their long-term impact on health. While global evidence has established strong associations between ACEs and adverse outcomes, research in India remains limited and fragmented. This scopin...

Identification of a nanosecond isomer of $$^{164}$$Tb

Abstract This letter reports on the identification of a new isomeric state of $$^{164}$$ 164 Tb ( $$Z=65$$ Z = 65 , $$N=99$$ N = 99 ), which was measured with the DESPEC setup at the GSI Helmholtzzentrum für Schwerionenforschung GmbH following the first relativistic fragmentation...

Integrating molecular engineering and artificial intelligence to overcome clinical and manufacturing challenges in CAR-T therapy

Chimeric antigen receptor (CAR) T-cell therapy has demonstrated remarkable efficacy in addressing hematological malignancies. However, its broader clinical application in other cancer types is still limited by key challenges like antigen escape, on-target/off-tumor toxicity, redu...

A new single-segment group explicit iteration scheme based on cubic spline approximation for 1D nonlinear parabolic partial differential equations

In this article, we present a new two-step cubic spline method of O(2,4) for estimating the numerical solution of a 1D nonlinear parabolic partial differential equation with appropriate conditions at the initial time level and Dirichlet conditions along the boundary. Furthermore,...

Integrating Artificial Intelligence in School Psychology: Practical Strategies to Support Adolescent Wellbeing in Indian Schools

The integration of artificial intelligence (AI) in school settings is transforming how students learn and receive support. While AI tools such as adaptive learning systems and chatbots offer opportunities for personalised learning and early identification of student needs, their...

Effect of Mg doping and dopant-vacancy arrangement on the structural stability, electronic structure, and Li-ion migration of anti-perovskite Li3ClO: A first-principles study

Lithium-rich anti-perovskites have attracted considerable attention as potential solid electrolytes for all-solid-state lithium batteries because of their structural versatility and defect-mediated Li-ion transport. Among them, Li 3 ClO has emerged as a promising model system for...

Rapid Transformation of Carcinogenic 4‐Nitrophenol by Nanoparticles Synthesized Using Recycled Copper Waste: A Sustainable Circular Economic Approach

ABSTRACT Novel Cu/Cu 2 O‐nanoparticles have been synthesized by the most economical electrochemical method utilizing metallic waste. 4‐NP is a toxic pollutant affecting both animal and plant kingdom, necessitating its elimination from environment. This study demonstrates that the...

A Comparative Study of Xception-LSTM and Xception-GRU for Deepfake Detection in Journalism

This research addresses the growing threat of deepfakes, AI-generated synthetic media, to journalism and public trust in digital content. Accurately detecting manipulated videos and images remains a critical challenge, especially under computational and data constraints. The stud...

Chicken Nation: Permissibility, Power, and the Social Life of Meat in India

This article examines the cultural and political significance of chicken in contemporary India, situating its circulation within histories of caste hierarchy, religious distinction, and majoritarian politics. While scholarship has foregrounded beef as a site of prohibition and pu...

Egg Cannibalism Affects Growth Development, Reproduction, and Fitness of Aphidophagous Coccinellids, Hippodamia variegata, and Menochilus sexmaculatus

ABSTRACT We investigated how egg cannibalism affects growth, development, reproduction and progeny fitness of aphidophagous coccinellids, viz. Menochilus sexmaculatus (Fabricius) and Hippodamia variegata (Goeze). Egg cannibalism provided immediate benefits to first instars by exp...

Space debris and outer space sustainability: legal challenges

By 2025, humankind had reached a turning point in space. The orbital environment, once considered effectively unlimited, is now increasingly understood as a finite and congested operational domain. This article presents an in-depth evaluation of the legal and policy regimes for s...

Synergistic Ag/In Co-doping-Induced Band and InterfaceEngineering in p-Type CuSe on Carbon Fabric for a FlexibleThermoelectric Generator

Abstract In the present work, a dual-doping strategy with silver (Ag) and indium (In) in copper selenide (CuSe) nanoparticles on conductive carbon fabric (CF) has been employed with a facile hydrothermal technique. This co-doping strategy outperforms single-element doping by enab...

Efficient Feature Selection with Multiple Equivalent Subsets Using a Multi-objective Quantum-inspired Evolutionary Approach

Abstract In many real-world applications, it is useful to identify multiple distinct feature subsets that achieve the same classification accuracy with the same number of features. This gives domain experts more flexibility to choose feature combinations based on cost, availabili...

The Indus Script: A Structural Phonetic Framework for Decipherment via the 'Parmanu' (Phonetic Atom) Theory

The decipherment of the Indus Valley Script (c. 3300–1900 BCE) has long been stalled by "meaning-hunting"—the erroneous attempt to map signs directly to whole words of specific language families (e.g., Dravidian or Indo-Aryan). This paper introduces a paradigm shift via the 'Parm...
