Numerical evaluation of post fire capacity of reinforced concrete columns

This study employs finite element modelling to investigate the behaviour of reinforced concrete (RC) columns subjected to fire including cooling phase. Although previous experimental studies have observed the response of RC columns subjected to fire, still there remains a need of...

Robust Spin Splitting and Strain-Controlled Optical Response in Monolayer CrC2N4 for Valleytronic and Optoelectronic Applications

Abstract The atomically thin CrC2N4 has recently emerged as a promising two-dimensional semiconductor, yet its spin−orbit-coupled (SOC) valley physics and strain-tunable nanoscale optical response remain largely unexplored. Here, we investigated the electronic, valley, charge-tra...

Optimized Thermal Dissipation of ISO SNGA 120408 Carbide Tool by Tuning Parameters: A Numerical Study

ABSTRACT In metal cutting, excessive heat generation adversely impacts tool life, dimensional accuracy, and the metallurgical properties of the workpiece, highlighting the necessity for thermal management of the cutting insert. This study numerically investigates key thermal mana...

How Many PM2.5 Sensors are Needed to Estimate Daily and Annual Deployed-Network Mean Concentrations in City-Scale Sensor Networks?

Abstract Low-cost PM2.5 sensors make it possible to deploy dense networks, but the density required depends on the monitoring objective and local variability. We examined how well smaller subnetworks reproduce deployed-network daily and annual or study-period mean concentrations...

Early malaria risk screening in Nigerian minors using AutoML and cluster-based analysis of non-clinical survey data

Malaria remains a major public health challenge in sub-Saharan Africa, with Nigeria accounting for a substantial proportion of the global malaria burden, particularly among children under five years of age. Although rapid diagnostic tests (RDTs) enable timely screening, false-neg...

Triplet-based species tree estimation: Sensitivity to gene tree rooting (or lack thereof)

Species tree estimation often involves phylogenomic methodologies that incorporate multiple genes sampled across the genome. However, gene tree heterogeneity (discordance), often attributed to Incomplete Lineage Sorting (ILS), presents a significant challenge to accurate species...

Techno-economic analysis and life-cycle assessment of pyrolyzed hydrochar production from waste corn stover

Corn stover, an abundant agricultural residue, represents a significant untapped resource for producing value-added materials through thermochemical conversion. Pyrolyzed hydrochar, a promising carbon-rich adsorbent whose performance is subjected by pyrolysis conditions. Attentio...

Optimization of double-diffusive mixed convection for a hybrid nanofluid system: A numerical and statistical coupled approach

There has been a lot of research on nanofluid convection, but not much on the impacts of double-diffusive mixed convection, hybrid nanofluids, and complex geometries like L -shaped cavities using combined statistical and numerical approaches. To fill that important gap, the aim i...

Comparative evaluation of different sol–gel processed M-type barium hexaferrite on structural and antimicrobial efficacy

Barium hexaferrite has gained increasing attention for biomedical applications, including antimicrobial coatings and targeted drug delivery alongside its established use in magnetic solid-state devices. Therefore, understanding how synthesis routes influence its formation and bio...

Observation-constrained clear-sky direct radiative forcing of black carbon containing aerosols reveals distinct radiative regimes across urban Asia

Black carbon (BC) aerosols exert a strong yet uncertain influence on the atmospheric energy balance, yet their radiative forcing estimates remain poorly constrained. Current top-down and bottom-up approaches remain limited in resolving how microphysical evolution and column prope...

Interlayer-engineering of charge order wavevector in kagome metals

Charge orders in the kagome metals AV$_3$Sb$_5$ sit at the center of a rich phase diagram that also includes superconductivity, nematicity, and signatures of time-reversal-symmetry breaking. Yet even the basic question of which charge ordering wave vectors are intrinsic, and whic...

Attomolar Detection of HIV‐1 With Label‐Free RCA‐rCRISPR on Smartphone

ABSTRACT HIV remains a major global public health challenge, causing 42.3 million deaths since its discovery in the early 1980s. Despite progress in prevention and treatment, around 60% of people with HIV (PWH) remain undiagnosed in resource‐limited regions due to the lack of ine...

Compressed stabilized earth blocks incorporating cement and waste cotton fiber: Mechanical, durability and life-cycle performance

Earthen construction offers a low-energy, low-carbon alternative to conventional masonry, but the limited strength and moisture sensitivity of unfired earth restrict its structural use. This study evaluates waste cotton fiber, an abundant textile-industry by-product, combined wit...

Wave energy harvesting: Extraction of maximum energy from the oceanic wave by design optimization of a linear electrical generator

Due to the intermittent nature of oceanic waves, extraction of maximum wave energy is challenging by only improving the efficiency of direct drive linear electrical generators (LEGs). Site specific wave characteristics further complicate performance optimization. The existing des...

Comparative assessment of OPC and portland composite cements on the rheology and strength of nylon fiber-modified self-compacting concrete

Abstract This study investigates the combined effects of Portland composite cement type and nylon fiber dosage on the fresh-property compliance and 28-day mechanical performance of self-compacting concrete (SCC). An empirical SCC proportioning approach was adopted. Four OPC-based...
