No New Mathematical Insight Found for Navier-Stokes Problem — E8 Intelligence Research

FINDING: No new mathematical insight or discovery; the search results are primarily expository videos and one unverified arXiv preprint claiming a solution to the Navier-Stokes existence and smoothness problem. MATH: The Navier-Stokes equations for incompressible flow: \[ \frac{\...

Self-Governance of Common-Pool Resources Under Rapid Urbanisation: The Case of Lake Hawassa, Ethiopia

Contemporary common-pool resource (CPR) theories recommend self-governance as an effective management approach. This article investigates the implications of rapid urbanisation on CPR self-governance, using Lake Hawassa in Ethiopia as a case study. Drawing on semi-structured inte...

Valley-Polarized Transport in Graphene Induced by Asymmetric Strain and Ferromagnetic Modulation

In this work, we theoretically investigate the valley-dependent electron transport properties of graphene modulated by two strained regions and a single ferromagnetic stripe based on the Dirac equation and the transfer-matrix method. By constructing a multi-region model, the cond...

A maize canopy phenotypic traits detection method based on improved Mask2YOLO cascade deep learning network

High-throughput detection of phenotypic traits of the maize canopy is significant for cultivar selection, cultivation, and management. Addressing the difficulty of rapidly recognizing maize canopy organs from field-acquired images, this study proposed a maize canopy phenotypic tr...

Oxindole-pyrrole-piperazine hybrids as novel α-glucosidase inhibitors: Design, synthesis and evaluation

α-Glucosidase acts as one therapeutic target for diabetes. For finding novel α-glucosidase inhibitors, oxindole-pyrrole-piperazine hybrids ( OPP-1∼24 ) were synthesized. Inhibition evaluation revealed that all hybrids ( OPP-1∼X24 ) demonstrated potent α-glucosidase inhibitory act...

Closed-Face Integrality and Exact Conditional Termination for Cone-Monotone Integer Equality Relations

This paper gives an exact characterization of conditional termination for a class of nondeterministic homogeneous integer equality relations defined by Bλ = Aλ′ over nonnegative integer coefficient vectors. Under pointedness of the source cone, nonzero source generators and cone-...

Soil Yeasts from Sugarcane Agroecosystems: Nutrient Cycling and Biocontrol Potential in Agricultural Systems

Soil yeasts represent a significant component of the agricultural microbiota and possess high ecological and biotechnological potential in production systems such as those for sugarcane. This review analyses the importance of these microorganisms in fundamental processes related...

Hormone therapy ( HT ) in women with premature ovarian insufficiency or early menopause: Time to think of a new paradigm for healthy aging. A joint FIGO and IMS position paper

Premature ovarian insufficiency (POI) and early menopause (EM) affect millions of women worldwide. Compared with normal menopause, they confer a longer duration of estrogen deficiency and are associated not only with a shorter lifespan, but with a reduced healthspan, owing to an...

A Cross-Sectional Study of Food Insecurity, Mediterranean Diet Adherence, and Gut-Derived Metabolites and Their Associations with Glycemic Control and Macrovascular Complications in Adults with Type 2 Diabetes

Objective: This study aimed to investigate the combined associations of food insecurity and Mediterranean diet adherence with glycemic control and to determine whether gut-derived metabolites differ according to food insecurity and macrovascular complication status in adults with...

Bioinspired Wettability Engineering Enables Efficient Exhaled Breath Condensate Harvesting for Wearable Respiratory Monitoring

Abstract Efficient collection of exhaled breath condensate (EBC) remains a major challenge for wearable respiratory monitoring because limited sample yield often compromises analytical sensitivity and signal reliability. Herein, we report a smart bioinspired mask that enables eff...

Nature-Based Solutions for Office Workers: A Randomized Controlled Trial on Indoor Plants to Enhance Well-Being and Productivity

Most of the global population lives and/or works in urban areas with limited access to green spaces. Integrating nature-based solutions (NBS) into indoor environments has emerged as a promising intervention strategy for enhancing indoor environmental quality (IEQ) and promoting h...

Fe(III)-MediatedOxidative [5 + 1] Cyclization forthe Highly Site-Selective Synthesis of Functionalized Quinoline Derivatives

Abstract We describe a method for the construction of highly functionalized quinoline derivatives from enaminones via an oxidative [5 + 1] cyclization. A plausible mechanism may involve a cascade sequence including single-electron transfer (SET), radical Michael addition, elimina...

The Hyperspherical Radius as Cosmic Time — a Geometric Hypothesis for Cosmological Expansion and Quantum Nonlocality

This note is a versioned corrigendum to The Hyperspherical Radius as Cosmic Time (Version 6). It records three changes that the reader of Version 6 must apply. First, Version 6 omitted the substantial prior literature on linearly expanding cosmologies; the relevant antecedents an...

Combined Post- and Precapillary Pulmonary Hypertension in Patients With Advanced Heart Failure

Pulmonary hypertension associated with left heart disease, or group 2 pulmonary hypertension, is common in patients with advanced heart failure. In at least a third of these patients, the pulmonary pressures are disproportionately elevated relative to left heart filling pressures...

Time-Varying Electromagnetic Systems - Challenges and Methodologies

Time-varying (TV) electromagnetic (EM) systems and devices introduce a fundamentally new framework in EM theory by extending classical concepts beyond traditional time-invariant formulations. In conventional EM systems, temporal invariance combined with the steady-state assumptio...

Kichwa joke-telling in global tourism

Abstract This study examines how Otavalan Kichwa vendors, cultural experts, and migrants deploy joking as a multisensory form of intimacy that reshapes cross‑cultural learning of “heritage” within global tourism economies. Jokes, I argue, can be used instructionally and tacticall...

A Checklist to Aid Clinicians in Excluding Specific Learning Disorder in Adolescents with Academic Difficulties: Delphi Validation

Background: Among treatment-seeking adolescents, academic difficulties that are secondary to factors such as emotional disturbances may respond to relatively simple educational or behavioral interventions. In contrast, those with specific learning disorder (SLD) typically require...

pH-Responsive Probe for β-Lactamase-based Protein Tag in Fluorescence Imaging of Receptor Endocytosis

Abstract Fluorescence imaging of the local pH environment surrounding proteins offers an understanding of cellular processes, including receptor endocytosis. We herein develop a pH-responsive fluorescent β-lactamase inhibitor for protein labeling via a genetically encodable β-lac...

Sharp Asymptotics for Abelian Covers of Groups with Bounded Noncommutativity

We determine the sharp exponential growth rate of the minimum number of abelian subgroups required to cover a group with bounded pairwise noncommutativity. Let omega(G) denote the largest size of a pairwise noncommuting subset of a group G, let a(G) be the least size of an abelia...

CGRD: An Exemplar-Free Extension of Knowledge Distillation for Class-Incremental 3D Point Cloud Semantic Segmentation

Class-incremental three-dimensional point cloud semantic segmentation requires models to learn newly introduced categories while preserving previously acquired knowledge without storing historical point clouds. This setting is challenged by representation drift during incremental...
