Lead-Time Sensitivity of GFS Forecasts for the Deadly 2011 Nova Friburgo Disaster (Brazil): A Hindcast-Based Synoptic and Thermodynamic Assessment

Abstract The catastrophic rainfall of 11–12 January 2011 triggered hundreds of landslides and flash floods in the mountainous region of Rio de Janeiro state, Brazil, with Nova Friburgo among the affected municipalities. This paper assesses how the predictability of this event dep...

Modeling effective doses of therapeutic antibodies targeting clustered surface receptors

Abstract A longstanding practice for therapeutic dosing of monoclonal antibodies is to identify the maximally tolerated dose. However, this approach has encountered limited success with some antibodies, especially in failed cancer trials. Here we report on an alternative dose-fin...

Factors associated with selection of total hip arthroplasty versus hemiarthroplasty for femoral neck fracture in older adults: a nationwide analysis of 99,084 cases

BACKGROUND: Surgical management of displaced femoral neck fractures in older adults typically involves hemiarthroplasty or total hip arthroplasty (THA). Although clinical guidelines suggest that THA may be considered in selected healthier and cognitively intact patients, real-wor...

On the microlocal regularity of the Gevrey vectors for second order partial differential operators with non negative characteristic form of first kind

Abstract We study the microlocal regularity of the analytic/Gevrey vectors for the following class of second order partial differential equations $$\begin{aligned} P(x,D) = \sum _{\ell ,j=1}^{n} a_{\ell ,j}(x) D_{\ell } D_{j} + \sum _{\ell =1}^{n} i b_{\ell }(x) D_{\ell } +c(x),...

From Binary Randomness to Macroscopic Emergence A Microscopic Derivation of Nonuniformity Emergence, with the Load-Bearing Link Graded in Four Layers

Abstract. The macroscopic phenomenological equations of open systems — an income-minus-expenditure master equation, a gradient-flow relaxation, and a quasi-potential landscape — are usually posed as postulates. This paper supplies the microscopic link. Starting from a minimal den...

Appraisal of Built-Environment Agencies' Roles on Building Collapse in Lagos State, Nigeria

This study examined the roles, effectiveness, and spatial distribution of built environment agencies in mitigating building collapse in Lagos State, with the objective of assessing institutional performance, identifying operational gaps, and proposing improvement strategies. The...

Real-world analysis of depression-related adverse events associated with the adsorbed anthrax vaccine: integrating pharmacovigilance signals, machine learning risk prediction, and transcriptomic mechanisms

Abstract Background Anthrax remains a life-threatening zoonotic disease in resource-limited settings. Adsorbed anthrax vaccine (AVA, BioThrax) is the only United States-authorized preexposure prophylaxis for high-risk Bacillus anthracis exposure. Although AVA safety has been desc...

Detailed study of bifurcations in a rate model with excitatory and inhibitory neurons and adaptation

The dynamical behaviour of a population-based rate model with firing adaptation is studied. An excitatory and inhibitory population of neurons is recurrently coupled and a negative feedback term is added to the excitatory population as firing adaptation. In several studies of the...

Emerging Trends in Robotics and Automation for Sustainable Development in Nigeria

Nigeria faces significant developmental challenges in agriculture, healthcare, waste management, and infrastructure, which hinder progress toward the Sustainable Development Goals (SDGs). Emerging trends in robotics and automation offer transformative solutions to enhance efficie...

Job Skills and Occupations: PRISMA 2020 Systematic Literature Review Screening and Analysis Dataset

This dataset contains the complete screening, eligibility assessment, relevance scoring, thematic classification, and methodological synthesis used in a systematic literature review on job skills and occupations. The review follows the PRISMA 2020 framework and is based on record...

Oxidative stress in pigs and opportunities with selenium-containing amino acids

Modern pig farming practices, characterized by highly-productive and fast-growing genetics, early weaning, and uncontrolled factors such as heat stress and various nutritional challenges, impose cumulative stress on the animal. Elevated concentrations of reactive oxygen species w...

Recovery of gait after ankle fracture surgery following early mobilization and weight-bearing

BACKGROUND: Ankle fractures are among the most common fractures in adults. Despite significant advancements in surgical techniques, the postoperative treatment regimens remain conservative. This study aims to objectively evaluate gait recovery following early mobilization and wei...

The Principle of Spatial Gradient Excess Screening Length, the Jeans Instance, and a Cross-Scale Applicability Map

Abstract A few nodes carrying most of the flux while vast regions remain quiescent is a spatial pattern that recurs from cities and wealth to stars and galaxies. We propose the principle of spatial gradient excess, which unifies such concentration under a single screened-field pi...

Perceived Environment and Socioeconomic Impact of Quarrying Activities on Residents in Abeokuta, Nigeria

Quarrying is an important economic activity that supplies construction materials and creates employment opportunities. However, its environmental and socioeconomic consequences on nearby communities remain a growing concern in many developing countries. This study assessed the pe...

ACCELERATING THE GROWTH OF COMMERCE IN NIGERIA: NACCIMA AS A VITAL PLAYER

This study examines the role of the Nigerian Association of Chambers of Commerce, Industry, Mines and Agriculture (NACCIMA) in accelerating commercial growth in Nigeria within the context of economic policy uncertainty, trade facilitation, and the implementation of the African Co...

A Defect–Convexity Filtration for Regular-Simplex-Faceted Polytopes: Exact spectra, gaps, re-entry, and quantitative realization thresholds

We propose a two-parameter framework for organizing convex polytopes whose facets are regular simplices or controlled perturbations thereof. The framework separates metric regularity of the edge set from strict convexity of the gluing. For a convex simplicial polytope P, we intro...

This research study assessed the influence of an Islamic Values-Based Management (IVBM) intervention to enhance teacher collaboration and organizational effectiveness in elementary schools in Simunul, Tawi-Tawi. Using a quasi–experimental mixed methods design, the study examined...

Decolonising Liberal Democracy: Amílcar Cabral's Political Thought and the Reconstruction of Participatory Democracy in Africa

The persistence of democratic challenges in Africa has generated debates about whether liberal democracy, as inherited and practised across the continent, adequately responds to African political realities. While existing explanations often emphasise weak institutions, poor leade...

THE IMPACT OF INFLUENCER MARKETING ON DOMESTIC TOURISM DECISIONS AMONG HO CHI MINH CITY RESIDENTS IN VIETNAM: TESTING THE MODERATING ROLE OF INCOME

Abstract Influencer marketing has become an important source of information that influences domestic tourism decisions in emerging markets. However, there is limited research on the role of individuals’ economic conditions in explaining the translation of influencer attributes fr...

The Impact of Writing Instruction for English Language Learners in the United States: A Meta-Analysis

Abstract Writing is a cornerstone of academic success, yet English language learners (ELL) in the United States must learn to write while also developing English proficiency. Although descriptive reviews suggest that writing instruction can benefit these learners, no prior meta-a...
