Exact Angular Critical-Point Counts for e^z ± 1

For f_a(z) = e^z + a, a = ±1, we count the distinct angular critical points of log |f_a| on every zero-free circle of radius r ≥ 12. Writing N_p(r) for the number of zeros in the disk, we prove that the critical-point count N_osc(r) satisfies 0 ≤ N_osc(r) − 2N_p(r) ≤ 4, with both...

Enhancement mechanism of Ce-Ni-modified vanadium–titanium magnetite in chemical looping hydrogen production

Vanadium-titanium magnetite concentrate (VTM) oxygen carriers suffer from inherently low redox activity and sluggish oxygen migration rate, which severely constrain their application in high-efficiency chemical looping hydrogen production. To overcome these limitations, this stud...

A robust and reliable method for malware classification using hybrid features and gradient boosting

The most significant problem facing software security firms in the current cybersecurity system is the fact that new strains of malware keep on appearing. The achievement of successful detection of malicious software based on both static and dynamic data remains unmet despite the...

Solar-driven photocatalytic ceramic membrane reactors from tunisian clay for efficient paracetamol degradation

Pharmaceutical residues such as paracetamol are increasingly detected in aquatic environments, raising concerns about their persistence and potential ecological impact. In this study, a solar-driven photocatalytic membrane reactor (PMR) was developed using low-cost ceramic membra...

Right-Turn Spectrum Languages: One-Pebble Completeness and Deterministic Dilation Obstructions

The paper develops a systematic impossibility theory for tree-language recognition, establishing fundamental limits on what restricted computational models can recognize. It introduces parametrized right-turn spectrum languages and proves an infinite family of impossibility theor...

Whole genome pool sequencing reveals genomic variation in field Haemonchus contortus isolates in Sweden

Abstract Background Haemonchus contortus is a major gastrointestinal parasite of small ruminants worldwide. Its large effective population size, high fecundity, and extensive genetic variation promote rapid adaptation and the development of anthelmintic resistance. Resolving geno...

Development and COSMIN-based psychometric evaluation of the activities of daily living questionnaire for elderly iranian patients with chronic obstructive pulmonary disease (ADLEC): a sequential exploratory mixed-methods study using hybrid concept analysis

Activities of daily living (ADL) are substantially compromised in elderly patients with chronic obstructive pulmonary disease (COPD) owing to exertional dyspnoea and fatigue. Generic instruments fail to capture disease-specific functional limitations, whereas existing disease-spe...

Integrating Classical and Contemporary Perspectives on Leech Therapy in Eye Disease: An Ayurveda-Biomedicine Evidence Synthesis

Background: Jalaukavacharana (leech application) is a type of Raktamokshana (bloodletting). Ayurvedic texts describe it for diseases caused by vitiated Pitta and Rakta. Many eye diseases (Netra Roga) are described as Pitta-Rakta diseases, and Ayurvedic eye doctors still use leech...

The effect of heat shock exposure duration on in vitro exsheathment and subsequent viability of Haemonchus contortus third-stage larvae

Abstract Helminth infections in livestock are a health concern across age groups and cause substantial global economic losses. Three main anthelmintic classes, benzimidazoles, macrocyclic lactones, and cholinergic agonists, are used in small ruminants; however, resistance has eme...

Immobilized Thiol Catalysts for Native Chemical Ligation in Flow

Abstract Native chemical ligation (NCL) is a well-established research tool used to access long and complex peptides that cannot be efficiently synthesized by other means such as linear solid-phase peptide synthesis (SPPS). However, its broader application beyond the research lab...

School District and Neighborhood Socioeconomic Factors in Adolescents’ Exposure to School Lockdown Responses to Violent and Firearm-Related Threats

School lockdowns can negatively affect student well-being. We used Bursik and Grasmick’s systemic reformulation of social disorganization theory to examine school district- and neighborhood-level socioeconomic risk factors for children’s exposure to school lockdown events caused...

Hidden service climate archetypes in hotels: A text-analytic framework using employee narratives

This study investigates how hidden backstage organizational climates in hospitality settings shape latent service performance risks by leveraging digital employee voice data that are typically inaccessible through traditional survey methods. Drawing on 11,336 Glassdoor reviews fr...

RpoS and PmrA Induced Resistance to Polymyxin B is Independent of arnT Expression in Pseudomonas aeruginosa

Adaptive resistance of Pseudomonas aeruginosa to polymyxin B, a drug of last resort, is an emerging problem worldwide. The purpose of this study was to better understand the mechanism of transcriptional regulation of polymyxin B resistance in P. aeruginosa. One proposed regulator...

CCR-k Arithmetic Refinement: p-Adic Resonance, Ramification, and Arithmetic Density Laws

The paper develops the arithmetic refinement of our original CCR-k General Theory, which arose from the higher-order structure of chronological carry and exact pushdown normalization. Whereas the general theory establishes the higher-order transport equations and their Stirling-t...

AI-BASED EMERGENCY BLOOD DONOR MATCHING AND RECOMMENDATION SYSTEM

This paper presents an AI-Based Emergency Blood Donor Matching and Recommendation System designed to improve the efficiency of blood donor discovery and emergency coordination. The proposed system aims to connect patients or healthcare providers with suitable blood donors based o...

Treatment persistence and clinical outcomes following subcutaneous methotrexate initiation in patients with rheumatoid arthritis: a real-world observational study

ABSTRACT Objectives This study aimed to evaluate treatment persistence and safety following subcutaneous methotrexate (MTX) initiation in Japanese patients with RA and to assess clinical outcomes among patients who directly switched from oral to subcutaneous MTX. Methods This ret...

Optimal configuration of complementary coupled energy supply stations for remote offshore hydrogen refueling and charging

With the implementation of China's “offshore hydrogen island” project and the development of hydrogen and electric ships, the proposal of “renewable energy + energy storage + combined hydrogen production” has opened up new ideas for remote offshore energy supply. However, extendi...

Turning excess sludge into a resource: Driving simultaneous nitrogen removal and sludge reduction under low dissolved oxygen

The simultaneous partial nitrification, anammox, denitrification, and fermentation (SNADF) process is highly desirable for sustainable wastewater treatment. However, simultaneously maintaining efficient sludge reduction and nitrogen removal in SNADF systems under low dissolved ox...

Loss of power by degree of heaping in covariables

Abstract Heaping or digit preference is frequently occurring in health research data as well as in deliberate data masking. We investigate the associated loss of power associated by degree of heaping by simulation and illustrate the effect with a real dataset. Moderate heaping le...
