Recent Advances in Synthesis and Characterization of Niobium Catalysts: A Review

Niobium-based catalysts have emerged as highly adaptable materials for reactions under heterogeneous conditions, owing to significant advances achieved in synthetic methodologies and characterization strategies. In this review, special attention was paid to analyzing the main met...

Readiness, perceptions, and challenges of pharmaceutical e-labelling implementation among healthcare professionals in Malaysia

Electronic labelling (e-labelling) offers a digital alternative to conventional printed package inserts, disseminating up-to-date pharmaceutical information via Quick Response (QR) codes. While e-labelling addresses key limitations of paper-based systems, including space constrai...

Metric and Levi-Civita Connections on Regular Hom-Lie-Rinehart Algebras

In this paper, we study regular Hom-Lie-Rinehart algebras and extend several classical geometric notions to this framework. In particular, we develop the theory of pseudo-Riemannian metrics, connections, curvature tensors, and torsion tensors in the setting of regular Hom-Lie-Rin...

Towards emotion-aware online learning through facial expression analysis

Purpose Online learning environments provide rich digital traces of learner activity, yet they offer limited access to the non-verbal affective cues that instructors naturally observe in face-to-face classrooms. This study investigates facial expression analysis as an affective s...

Keeping Score: what a year of recording our own defects taught us about evidence for automated decisions

An operator applying serious effort to checking his own work, with tooling built for the purpose, found fewer than half of his own defects without help. This paper reports that record: ninety-five numbered items over a year, a taxonomy of ten species of defect, and the share foun...

Ratio-Dependent Regulation of Butyrate Production by 2′-Fucosyllactose and Fructooligosaccharides in a Bifidobacterium bifidum-Faecalibacterium prausnitzii Co-Culture

An appropriate 2′-fucosyllactose (2′-FL) and fructooligosaccharides (FOS) mixing ratio may enhance butyrate production through substrate complementarity and metabolite-mediated interactions; however, the substrate balance required for this effect remains unclear. This study inves...

Rulings involving age discrimination

An overview of the key topics faced by higher education professionals with citations to noteworthy cases, statutes, regulations, and additional sources.

E8 Phi‑Coupled Phononic Metamaterial with Hierarchical Bandgap — E8 Intelligence Research

By arranging 240 piezoelectric elements in the exact geometry of the E8 root system and driving them at the base 132 Hz frequency with successive phi‑phase shifts, a self‑similar 8‑fold phononic bandgap emerges. Each of the eight phase‑locked sub‑lattices reproduces the E8 root p...

A media ecology of hyperlocal resistance-the Indian farmers’ movement

This article examines how protestors navigated a collapsing media environment during the Indian farmers’ movement of 2020–2021, one of the largest and most sustained protests in the country’s democratic history. Triggered by the passage of controversial agricultural marketing law...

Performance-Based Seismic Evaluation of Reinforced Concrete Moment-Resisting Frames: A Comparative Study of FBD and DBD

The seismic performance of reinforced concrete (RC) frame structures has traditionally been evaluated using force-based design procedures, wherein seismic demand is represented through equivalent lateral forces derived from elastic response spectra. Although this approach has bee...

Association Between Graves’ Disease and the Risk of Thyroid Carcinoma: The Role of Clinical, Metabolic, Hormonal, Immunological, and Ultrasound Biomarkers

Background: The relationship between Graves’ disease (GD) and thyroid carcinoma (TC) remains controversial, particularly regarding the predictive value of metabolic, hormonal, immunological, and ultrasound biomarkers. We performed a systematic review and meta-analysis to evaluate...

RPS27L Maintains Nucleolar Homeostasis to Regulate Proliferation and Differentiation of Bovine Skeletal Muscle Satellite Cells

The in vitro expansion of bovine skeletal muscle satellite cells (SMSCs) is critical for cultured meat production. Here, we investigated the role of ribosomal protein S27-like (RPS27L) in regulating satellite cell proliferation and differentiation. RPS27L knockdown markedly inhib...

Neural dynamics underlying minute-timescale persistent behaviour in the human brain

Pursuing longer-term goals relies on representations of task context that can be maintained over long periods of time and switched flexibly when goals change. Little is known about the neural substrate for maintaining context representations on the minute-timescale on which human...

Quantitative Analysis of the Influence of Spatial Morphology and Wind Environment on Elderly Thermal Comfort in Hot–Humid Residential Communities

As rapid population aging coincides with intensifying urban heat island (UHI) effects, ensuring the outdoor thermal comfort of the elderly in hot–humid regions has become a critical challenge. This study investigates the influence of residential spatial morphology and wind enviro...

Skeletal‐Muscle‐Inspired Superstrong Dynamic Covalent Liquid‐Crystal Elastomers With Exceptional Actuation Performance

ABSTRACT As an emerging actuator material for artificial muscles and soft robotics, dynamic covalent liquid‐crystal elastomers (DCv‐LCEs) enable network reorganization through dynamic bond exchange, allowing actuator reprogramming, actuation‐mode tuning, and material recycling. D...

Pharmacokinetic bioequivalence between (etonogestrel/ethinylestradiol 11.7/2.7 mg) NuvaRing ® and ornibel premium ® (etonogestrel/ethinylestradiol 8.25/2.6 mg), a novel polymer composition contraceptive vaginal ring

Objective This was a single-centre, randomised, single-ring insertion, 2-period, 2-sequence, crossover study designed to assess comparative bioavailability and thereby establish bioequivalence of two ethinylestradiol/etonogestrel vaginal rings (delivering 0.015/0.12 mg per day) a...

Elegance Over Constants: Defining Hard Competition Problems — E8 Intelligence Research

FINDING: The "hardest" competition problems are often defined by combinatorial or geometric elegance (e.g., windmill problem, Putnam 1987 A6, IMO 2011 Q2) rather than by deep constants or universal ratios. The linked videos and papers focus on problem-solving technique, not on fu...

The Arctic Winter Games: A subversive model of sporting event amid resonance blockers

This research draws on resonance theory to analyse how the Arctic Winter Games (AWG) mitigate features linked with professionalized sport events – dynamics that can act as resonance blockers – to sustain conditions more conducive to resonance. Utilizing a qualitative multimethod...
