Connected sequential Bargmann invariants and $$\mathcal CP~$$-sensitive geometric correlation structures in neutral meson systems

Abstract We investigate connected sequential geometric structures in correlated neutral meson systems within the framework of Bargmann invariants. Building upon previously developed third- and fourth-order rephasing-invariant geometric structures involving decay-projected conditi...

Thermal analysis of Casson nanofluid flow with Hall and activation energy effects

Abstract This study presents a comprehensive analysis of unsteady magneto‐convective heat and mass transport in Casson nanofluid flowing over a vertically stretching sheet within Forchheimer porous medium. The mathematical model incorporates an inclined magnetic field, Hall curre...

A text analytics based study of indian consumer attitudes toward adoption of sustainable products for circular economy

The adoption of circular economy strategies is only possible through proper education among young minds. However, to build an effective education model, it is necessary to consider knowledge gaps and current consumption patterns. The best option for daily-use products, around whi...

Passing the torch in knowledge-based SMEs: a dual-level moderated mediation analysis of business transfer readiness

Purpose The growing number of entrepreneurs exiting businesses is at risk for destroying small knowledge-based enterprises (KBEs). This study aims to investigate the cognitive mechanisms and dual-level boundary conditions associated with the willingness to sell amongst KBE owners...

Reliability of anthropometric indicators for assessing abdominal obesity

The rising burden of abdominal obesity (AO) has emerged as a significant global public health concern. Three commonly used measures for assessing AO are waist circumference (WC), waist-to-hip ratio (WHR), and waist-to-height ratio (WHtR). This raises an important question: which...

A Highly Robust Y‐Based Framework for Sustainable Catalysis and Synthesis of Bioactive Chromeno[2,3‐ d ]Pyrimidin‐8‐Amine Derivatives

ABSTRACT The synthesis of bioactive molecules through one‐pot multicomponent reactions under mild conditions is of significant interest for medicinal chemistry, though largely unexplored and challenging. Herein, we have reported a new Y(III)‐based chemically stable framework, IIT...

Isocoumarins a Privileged Scaffold: Isolation, Biosynthesis and Recent Progress in the Total Synthesis of Naturally Occurring Isocoumarins and Dihydroisocoumarins

Isocoumarins are naturally occurring benzo‐pyranones that constitute a class of polyketides derived from fungal metabolites and possess significant structural diversity and promising biological activity. Their core structural feature consists of a substituted benzene ring fused t...

Recent intensification of extreme precipitation over East Antarctica driven by increases in greenhouse gases and stratospheric ozone

Abstract. Extreme precipitation is a major contributor to the total precipitation over Antarctica and its variability. However, it remains poorly understood whether Antarctic extreme precipitation has undergone recent changes and, if so, whether these changes are anthropogenicall...

Geopolitical risk and renewable energy consumption: evidence from a global firm-level study

Purpose This paper aims to examine the impact of geopolitical risk (GPR) on the firm’s renewable energy consumption (REC) and to further examine whether this relationship varies for firms located in oil-importing and exporting countries, higher and lower energy diversification an...

Enhanced stability and controlled release of mandarin peel bioactives formulation for sustainable nutrition and next generation food system

This study explored the microencapsulation of mandarin (Citrus reticulata) peel extract using ionic gelation and freeze-drying to improve the stability and bioavailability of citrus bioactives. Encapsulation involved sodium alginate, maltodextrin (MD), gum arabic (GA), and Aloe v...

A 2D axisymmetric finite element analysis of thermal and moisture dynamics in a customized baking oven

Enhancing industrial baking processes needs precise numerical models for non-standard geometries to decrease energy consumption and preserve consistent product quality. This study addresses the shortcomings of conventional models, which often assume uniform, isotropic boundaries,...

Thermal-Hydraulic Performance of a Solar Flat Plate Collector Using CO2 under Superheated and Supercritical Regimes

This study presents a thermal-hydraulic assessment of an indirect solar water heating system employing carbon dioxide (CO2) as the heat-transfer fluid in a flat-plate collector. The work compares superheated and supercritical operating regimes under identical geometric, flow, and...

An exploration on what drives learners’ engagement in blended training at workplace

Purpose This study aims to identify and examine the key predictors of learners’ engagement (LE) in a blended learning (BL) training program. The goal was to assess the significance of perceived supervisor support on LE and examine the role of LE in their agility. Design/methodolo...

Process-structure-property relationship of ABS, PC, and ABS-PC blends in microscale additive manufacturing

Microscale fused deposition modeling (µ-FDM) requires thermoplastic materials with stable thermal behavior, controlled melt flow, and reliable interlayer mechanical performance. This study investigates the thermal, structural, morphological, and flexural behavior of µ-FDM-printed...

A decomposition approach for the multi-depot vehicle routing problem with heterogeneous fleets, pickup–delivery, time windows, and route balance

In this paper, we address the problem of equitable workload distribution in the multi-depot vehicle routing problem (MDVRP) with simultaneous pickup and delivery, time windows, and heterogeneous fleets. To ensure fairness, route balance is incorporated into the problem. This is m...

Chirality Unlocks Sub‐Terahertz Molecular Dynamics In Peptide Nanotubes

Low-frequency modes in the picosecond range play a key role in molecular recognition and biomolecular function. Here, we investigate how these dynamics at the interfaces of self-assembled peptide biomaterials relate to fine structural details of the supramolecular assembly. We re...
