On weighted inequalities for B -maximal operators

Let 1 < p < ∞ and w, v be two non-negative weight functions. In this paper, we provide a sufficient condition on w, v for the new maximal operator associated with the generalized translate operator Ty for each to be bounded from Lp,γ (v) to Lp,γ (w). Our condition is stronger, bu...

Babylonian Tablet Predates Greek Trigonometry by 1,000 Years — E8 Intelligence Research

FINDING: Babylonian Plimpton 322 tablet encodes exact sexagesimal Pythagorean triples — the earliest known trigonometric table, predating Greek trigonometry by over 1,000 years. | MATH: Sexagesimal (base-60) system; Pythagorean triples (a² + b² = c²) expressed as ratios of sides;...

Physics-based mathematical modeling of wear in ball screw drives

Ball screw drives are widely used to provide linear motion in Computer Numerical Control (CNC) machine tools. During prolonged operation, exposure to excessive cutting forces, or accidental collisions, the contact interfaces between the screw, balls, and nut experience accelerate...

Pragmatic Variation in Greeting and Farewell Formulae in Rural Austria

Greeting and farewell formulae are highly conventionalized routines that index social relations, regional norms and situational formality. This paper investigates pragmatic variation in greetings and farewells in rural Austria, focusing on age, region, setting and prosodic design...

Multiband condensate of magnons in two dimensions

Wavelike bosonic particles can accumulate in a single mode characterized by a particular wavelength, and such condensates are at the heart of phenomena such as superconductivity and superfluidity where usually a single complex number describes their state. If there are several fl...

Edible pedagogies: Designing with food, memory and emotion in the Bagel Studio

This article explores how food-making can support emotional, sensory and reflective learning in design education. Using a 15-week undergraduate and graduate industrial design studio as a case study, the project engaged 23 students in baking bagels to examine intersections of food...

Construction and application of evaluation models for online learning behaviour

Online learning not only makes full use of online resources to meet the diverse learning needs of students but also enhances their autonomy and information acquisition abilities. Through learning analysis techniques, the quality of online learning can be improved, thereby enablin...

High-sensitivity Cardiac Troponin I Changes Following Subcutaneous Needle Puncture, Restraint, and Venipuncture in Cynomolgus Monkeys

Background/Aim: Cardiac troponin I (cTnI) is a sensitive biomarker of myocardial injury in which procedure-related stress may cause mild, non-injury-related increases. This study aimed to characterize procedure-related variability of high-sensitivity cTnI and related biomarkers i...

A Redox-Initiated Cascade Approach to Furan-Functionalized Polyisoprene with Time-Dependent Antibacterial Activity

A novel furan-functionalized polyisoprene (Furan-PIP) was synthesized via a one-pot, redox-initiated cascade approach using tert-butyl hydroperoxide (TBHP) and tetraethylenepentamine (TEPA) as the initiating system. The polymerization of isoprene proceeded through radical emulsio...

Pretreatment Geriatric Nutritional Risk Index in RADPLAT-treated Patients With Oral Squamous Cell Carcinoma: A Pilot Study

Background/Aim: Pretreatment nutritional and inflammatory indices have been associated with prognosis in patients with oral squamous cell carcinoma (OSCC) undergoing surgery or chemoradiotherapy; however, their prognostic significance in patients treated with superselective intra...

Evolution, Plasticity, and Forgetting: Adaptation in a Simple Dynamic Environment

This record contains a small exploratory computational research project investigating the interaction between evolution, lifetime plasticity, and forgetting in a dynamically changing environment. The experiment uses a 2–6–2 neural network and compares three conditions: Evolution...

Computational strategies to address therapeutic resistance in estrogen receptor‐positive breast cancer: A narrative review of molecular docking, molecular dynamics simulations, and emerging therapeutic targets

Abstract Background Estrogen receptor‐positive (ER+) breast cancer represents the most common molecular subtype of breast cancer and remains highly responsive to endocrine therapy. However, therapeutic efficacy is frequently compromised by acquired or intrinsic endocrine resistan...

Moderate discrimination but attenuated predictive precision: a multi-model external validation of prolonged postoperative length of stay models after lumbar interbody fusion in an independent cohort

Prolonged postoperative length of stay (PLOS) following lumbar interbody fusion is associated with increased morbidity such as nosocomial infection and venous thromboembolism, healthcare costs, and impaired recovery. Several prediction models have been proposed to identify patien...

Cudrania tricuspidata Leaf-Derived Polysaccharides Attenuate Cisplatin-Induced Cytotoxicity in HEK 293T Cells via the Nrf2/HO-1 Pathway

Prolonged administration of cisplatin, a widely used chemotherapeutic agent, induces nephrotoxicity. Identifying natural compounds that attenuate cisplatin’s adverse effects on renal tissues would be of clinical value. Thus, the present study aimed to evaluate the cytoprotective...

Understanding genomic landscapes of differentiation in round-tailed horned lizards ( Phrynosoma modestum )

Population divergence is promoted by divergent selection and inhibited by gene flow, but the mechanisms of and relationship between these two processes remain poorly understood. Developing a well-informed hypothesis of the selective pressures underlying divergence in a natural po...

Role of School Nurses in Preventing Digital Addiction and Promoting Health Among School-Age Adolescents

Excessive digital technology use among adolescents has become an increasing public health concern, with growing evidence linking problematic smartphone, internet, gaming, and social media use to sleep disturbances, anxiety, depression, reduced academic performance, cyberbullying...
