A Study of Constrained Fractional Optimization Problems Involving Interval-Valued Functions

This study explores the optimality criteria for a class of fractional optimization problems characterized by interval-valued objective functions under constraints. These problems involve curvilinear fractional integral cost functionals that are path-independent and fundamentally...

The impact of cessation aids on sustained quitting and weight gain among adults with a quit attempt in the PATH study

Abstract Introduction This study aimed to compare cessation and weight gain among US adults in Wave 6 of the PATH Study. Methods Participants reporting a past year quit attempt (n = 2454) were grouped by cessation aid used: (1) medication (Rx), (2) nicotine replacement therapy (N...

Budgeted Reward Allocation: A Position on Unifying Sparse, Verifiable, and Hierarchical Reward Signals in LLM Post-Training

Reward hacking, verbosity, and hallucination are usually treated as separate failure modes in the post-training of large language models, addressed by separate mechanisms: reward shaping for verbosity, verifiable reward models (RLVR) for hallucination, hierarchical decomposition...

When Law Becomes a Shield for Crime: Administrative Concealment in Indonesia's Nickel Mining Sector

Background Indonesia's nickel industry encounters a regulatory dilemma in which governance mechanisms intended for oversight may be utilised for obfuscation. This article explores the conversion of mining documents from tools of regulation into frameworks for state-sponsored econ...

Near-threshold fatigue crack growth and fatigue strength of ER70S-6 steel processed by wire arc additive manufacturing

Abstract In this work, fatigue crack growth (FCG) tests were conducted to determine the threshold stress intensity factor ( ΔK th ) of ER70S-6 steel processed by wire arc additive manufacturing (WAAM). Samples were orientated with the crack direction (CD) both parallel (//) and n...

E-GOVERNANCE AND SERVICE DELIVERY IN THE NIGERIAN CIVIL SERVICE: AN ASSESSMENT OF THE AKWA IBOM STATE CIVIL SERVICE

This study examined e-administration and service delivery in the Akwa Ibom State Civil Service, focusing on the electronic payroll system and digitization of official records. The study was motivated by persistent administrative challenges, including ghost workers, payroll irregu...

Evaluating the Validity of Model Organisms: A Review and a New Framework for Biologists

Model organisms are central to biological research. Living organisms are models in the sense that the knowledge gained from their study is meant to be generalized. For example, experiments conducted on Drosophila or nematodes bring general knowledge on phenomena such as cell migr...

Dose and Time Dependent Elevations of Initial Unfractionated Heparin Anti-Xa Levels Associated With Low Molecular Weight Heparin Administration

Background: Intravenous unfractionated heparin (UFH) is routinely utilized for anticoagulation in acute care patients. Appropriate laboratory monitoring is an essential component of UFH therapy, including minimizing the effect of variables that interfere with the monitoring assay...

Stoic Self-Regulation and Depression: Between Acceptance and Resignation

This article examines possible relations between Stoic philosophy and modern psychological concepts in the context of depressive burden. Central Stoic principles - the distinction between controllable and uncontrollable factors, reflection on one's appraisals, and orientation tow...

Task Offloading with Temporal Awareness in Heterogeneous Cloud–Edge–Ground Systems

In post-disaster or infrastructure-limited remote-area environments where local terrestrial networking infrastructure is unavailable or severely degraded, heterogeneous cloud–edge–ground (CEG) systems provide a viable platform for computation offloading. Ground devices such as Io...

Sustainable use of phosphogypsum to enhance sandy soils fertility and wheat yield in arid environments

Abstract Purpose Sandy soils in arid regions have low fertility, poor structural stability, and limited water‐holding capacity. This study evaluated phosphogypsum (PG) as a soil amendment for improving sandy‐soil quality and wheat productivity under arid conditions. Methods A fie...

Weak, shallow, dry convection over Angola increases offshore stratocumulus cloud droplet number concentrations

Boundary-layer cloud interactions involving shortwave-absorbing aerosols remain one of the least understood aerosol influences on climate. Here, we find the highest stratocumulus cloud droplet number concentrations over the southeast Atlantic occur when agricultural fires coincid...

The Atlas: Phase-Locked Geometric Neural Manifolds on Mixed-Curvature Hyperbolic–Toroidal Product Spaces

We give a complete formal specification of Atlas, a phase-locked geometric representation substrate whose state space is the mixed-curvature Riemannian product M= Hn ×Tn. The hyperbolic factor carries semantic lineage (exponential volume growth, low-distortion hierarchy); the fla...

An Innovated Searching for Prospering China Auto Exportation Nations Value Analysis on Scientist's Behavior &Judgment through Sustainability I

The vehicle industry will stay an important occupation in the secondary industry that occupies more GDP (gross domestic product) allocation recently with promoting its electric vehicle into our deep level and helping us with its functional AI chip to one. Therefore, the new innov...

Contribution to Diagnostic Accuracy and Prognostic Significance of MicroRNAs in Thyroid Cancer

The incidence of thyroid cancer, the most common endocrine malignancy, has increased significantly, underscoring the need for improved diagnostic and prognostic methods. MicroRNAs (miRNAs) are small non-coding RNA molecules that regulate gene expression and play vital roles in ca...

MERLIN SCIENCE — E8 Phi‑Scaled Acoustic Metamaterial Achieves Sub‑Quantum‑Limit Coheren — E8 Intelligence Research

Here is the narration, revised to address the publisher's notes. --- Here is the finding in one clean sentence: We have embedded the 240 root vectors of the E8 lattice, scaled by the golden ratio, into a phononic crystal, and the resulting structure exhibits a bandgap that suppre...

Postmodernism, Hermeneutics, and the Problem of Narrative in Tom Stoppard's Rosencrantz and Guildenstern Are Dead

Postmodernism cannot be understood merely as a collection of literary, artistic, or philosophical techniques; rather, it refers to a profound transformation in the relationship between human beings and truth, history, language, subjectivity, science, art, and the possibility of c...

Loneliness, not isolation, is the missing link between social connectedness and mental health among midlife to older U.S. adults

Objectives To investigate whether loneliness or social isolation serves as the main pathway connecting social connectedness dimensions to mental health outcomes among midlife to older adults.Methods We examined longitudinal data from 4,963 adults aged 40–65 at baseline in the U.S...

Feed rate modulation for filling macroscopic surface pores in directed energy deposition: an experimental evaluation using boreholes as representative geometries
