Semiparametric hybrid air quality forecasting using prophet ensemble and feature selection

Due to air quality management and public health planning, accurately predicting PM2.5 concentrations is absolutely imperative. Having many lagged variables, interactions between pollutants and other temporal features means that high-dimensional environmental datasets (that may in...

Research on the Underlying Core Working Mechanism of Electric Motors

Existing theories of electric motors are largely developed based on analyses of macroscopic electromagnetic phenomena and mathematical fitting. Although they can meet the requirements of engineering calculation and equipment design, they fail to clarify the most fundamental physi...

YOLO-CNN-Based Multimodal System for Real-Time Structural and Bolt Analysis on a Semiautonomous Robot

Abstract This study introduces the Remote Automated Multi-Bolt Inspection Robot (RAMBIRobot), a novel system integrating machine vision and acoustic analysis for efficient, autonomous bolt inspection. Conventional bolt inspection methods are labor-intensive, prone to human error,...

Fibroblast Growth Factor 21 and Its Relationship with Central Precocious Puberty in Girls

Abstract Background Studies have found that obesity and insulin resistance are linked to central precocious puberty (CPP) in girls, while serum fibroblast growth factor 21 (FGF21) levels are associated with obesity and insulin resistance and related to ovarian development, reprod...

Ipsilateral inhibitory rTMS restores interhemispheric motor cortex balance and reduces phantom limb pain: an exploratory longitudinal nTMS mapping study

Abstract Background Phantom limb pain (PLP) is a debilitating condition associated with maladaptive neuroplastic changes following limb amputation. The prevailing neuromodulatory approach targets the deafferented contralateral motor cortex, yet interhemispheric imbalance is incre...

Draft genome of Streptomyces species VRG-4 isolated from leaf cutter ants of Uttarakhand

ABSTRACT We describe the draft genome sequence of Streptomyces sp. VRG-4, isolated from leaf cutter ants (Uttarakhand, India). The genome (9.3 Mb) consists of 83 contigs with 72% GC content. Genome annotation identified 8,243 protein-coding genes and 69 tRNA genes, which can be f...

INFLUENCE OF COMBUSTOR UNSTEADINESS ON THE AEROTHERMAL LOAD OF A HIGH-PRESSURE TURBINE STAGE USING SCALE-RESOLVING CFD SIMULATIONS

Abstract Aerothermal interaction between the combustor and the high-pressure turbine is critical for engine efficiency. Standard steady-state methods fail to capture the highly unsteady flow features at the combustor-turbine interface, leading to uncertainties in thermal load pre...

Secondary Narrow Nostril Deformity After Unilateral Cleft Lip Repair: Etiology, Classification, and Surgical Strategies

Secondary narrow nostril deformity after unilateral cleft lip repair remains a stubborn clinical challenge, with an incidence of approximately 84%. It compromises both nasal airway function and facial esthetics. The etiology is multifactorial, involving congenital tissue deficien...

Alkali-Fused CoalGasification Fine Slag for SimulatedPhenolic Wastewater Treatment: Adsorption–Oxidation Performanceand Mechanistic Investigation

Abstract Coal gasification fine slag (CGFS) is a large amount of industrial solid waste produced by the coal chemical process. Phenol in coking wastewater is a kind of refractory and highly toxic organic pollutants. In order to solve the two types of environmental problems simult...

Extraction and characterization of cellulose nanocrystals derived from wood sawdust for bioplastic production

This research study develops a sustainable approach to convert wood sawdust (WSD) from Cordia africana, found from in Bahir Dar, Ethiopia, in to cellulose nanocrystals (CNC) and CNC reinforced bioplastics (SDB). CNC was extracted through sequential alkaline treatment, bleaching a...

Utility of postcanine dental dimensions for body size estimation in Mustela (Carnivora)

Abstract Mustela , one of the most species‐rich and widespread genera of Carnivora, has a 4‐million‐year fossil record that mainly comprises permanent teeth, of which postcanines (premolars and molars) are most useful for taxonomic identification. To evaluate the utility of a sim...

The narrowing sex gap in lip and oral cavity cancer incidence in Spain: Thirty years of divergent age-period-cohort trends

Background Lip and oral cavity cancer (LOCC) accounts for a significant proportion of the overall burden of head and neck cancers, yet long-term sex-specific trends remain unclear. This study aimed to analyse sex-specific LOCC incidence trends in Spain from 1994 to 2023. Methods...

A Comprehensive Evaluation of Population Forecast Error for San Diego County and Its Jurisdictions

Highlights This study is the first in the San Diego region to evaluate population forecast error across multiple forecast vintages and increment years spanning more than five decades. Forecast accuracy declines with increasing forecast horizon, while forecast errors are also infl...

Non-Linear Impacts and Spatial Variations in Multidimensional Built Environments on E-Shopping Decisions: Evidence from Shanghai

While e-commerce has transformed consumption patterns, online shopping behavior remains influenced by the physical environment. Using Shanghai as a case study, this research applies machine learning, SHAP analysis, and K-Means clustering to examine the nonlinear impacts and spati...

Falerii Novi and the Via Amerina

Recent analysis of the results of the Ground-Penetrating Radar survey of Falerii Novi provides new perspectives on the relationship between the planned town and the via Amerina. Although it has long been suggested that the foundation of the new town in 241BC was linked to the con...

Computed tomography–based assessment of gluteal muscle asymmetry one year after total hip arthroplasty and its relationship with postoperative function

This study aimed to compare gluteal muscle quantity and quality between the operated and contralateral sides one year after unilateral total hip arthroplasty (THA). Muscle thickness, cross-sectional area (CSA), and muscle density of the gluteus maximus (Gmax), gluteus medius (Gme...

Pressure-ControlledDynamic Conversion of Replacement–DisplacementMechanisms During ECBM Recovery

Abstract Gas injection pressure is a key parameter controlling enhanced coalbed methane (ECBM) recovery, as it directly influences gas adsorption–desorption, diffusion-seepage, and the dominance of replacement-displacement mechanisms. In this study, carbon dioxide (CO2) and nitro...
