Impacts of ewe death and failure to rear a lamb on national production, profitability and greenhouse-gas emissions in New Zealand

Context Ewe death and lamb abandonment can contribute significantly to overall productivity and profitability of farming systems in New Zealand through impacts on lamb survival. Aims To find out how ewe death and failure to rear a lamb affect the production, profitability and gre...

Racial and ethnic disparities in perceived health and barriers to care among adults with hip osteoarthritis: a national analysis of 16,000 + patients from the all of us program

Abstract Objective To explore racial and ethnic disparities in perceived health, healthcare access, and perceived barriers among adults with hip osteoarthritis (OA) in a large, nationally representative U.S. cohort. Methods Cross-sectional analysis of 16,743 adults with hip OA fr...

Object biography of war relics: a case study on the Japanese pillboxes on Luk Keng Knoll

Abstract In the research context of the growing interest in the object biographies of World War II relics, this case study of the field surveys of the Japanese pillboxes on Luk Keng Knoll, Starling Inlet, in Hong Kong, is a good illustration of an object biography “written” by mi...

FedGAT: a backdoor attack based on global model feedback optimized triggers in federated learning

Abstract Federated learning (FL) has been widely applied in Internet of Things (IoT) systems. However, its inherently distributed nature makes it vulnerable to backdoor attacks. Existing attacks typically design triggers based on fixed patterns or local models, without considerin...

Organizing Science and Technology Activities to Develop Problem-Solving Competence for 5–6-Year-Old Children in Vietnam

This study aimed to evaluate the effectiveness of a four-step procedure for organizing science and technology activities in developing problem-solving competence among preschool children aged 5–6 years in Ho Chi Minh City, Vietnam. Using a sequential explanatory mixed-methods res...

Application of magnetically separable silica aerogel-supported palladium catalyst in the hydrogenation of aromatic nitro compounds

Abstract Palladium nanocatalyst has been prepared via sonication-induced reductive deposition for the hydrogenation of nitro groups, tested in the two industrially most significant nitro compound hydrogenation processes: nitrobenzene hydrogenation to aniline and 2,4-dinitrotoluen...

Machine Learning-Based Classification of Lower Urinary Tract Symptoms from Uroflowmetry: Evaluation Against Physician Decisions and Clinical Nomograms

Lower Urinary Tract Symptoms (LUTS) are commonly evaluated using clinician judgment and nomogram-based methods derived from limited physiological parameters. However, these approaches may not generalize across patient subgroups and may not fully capture patient-specific variabili...

Research progress on biosynthesis and regulation of monoterpenoid compounds

Abstract Monoterpenoids are an important class of plant volatile natural products with broad applications in the food, fragrance, pharmaceutical, and agricultural industries. However, their conventional production largely relies on plant extraction, which is often constrained by...

Non-Objects in the Ontology of EFOS: Typology, Status, and Relational Nature

This article presents a systematic description of non-objects – entities that do not fit into the simple distinction of "objects vs subjects" within the ontology of EFOS (Entity That Forming Objects and Subjects). Non-objects are defined as entities that, at a given moment (for a...

An investigation on TPB–NAM-based factors of the application of circular packaging

Abstract Faced with the pressure of packaging waste caused by e-commerce growth, Circular Packaging, as a sustainable logistics model that achieves multiple closed-loop circulations of packaging supported by standardized design and intelligent systems, is a crucial pathway for im...

“Beauty Servitude” as a Contested Metaphor in Chinese Competitive Debate: An Invitational Rhetorical Case Study

This study examines how the contested metaphor “beauty servitude” (服美役, fu mei yi) is constructed and negotiated in a widely circulated Chinese competitive debate about women’s beauty practices. Rather than treating the debate as representative of contemporary Chinese public d...

Preoperative lung ultrasound score and multifactorial predictors of 1-year mortality in geriatric hip fracture patients with pneumonia: a retrospective cohort study

Abstract Background Preoperative pneumonia severity independently predicts postoperative mortality in elderly hip fracture patients, yet accurate assessment remains challenging. This study evaluated lung ultrasound score (LUS) for predicting 1-year mortality and compared its pred...

Understanding pre- and post-COVID urban neighborhood dynamics: a study analyzing georeferenced tweets for New York City

Abstract Sudden disruptions, such as the COVID-19 pandemic, can reshape multiple dimensions of everyday urban life by affecting social interactions, mobility patterns, and the use of urban spaces. Previous research efforts trying to understand the consequences for citizens relied...

Public debt shocks and the interest-growth differential: a two-step CCE procedure with Monte Carlo evidence

Abstract This study proposes a two-step heterogeneous CCE procedure to estimate non-systematic variation in public debt and its effects on the interest-growth differential. We consider two dynamic DGPs that satisfy the rank condition and assume that the set of unobserved common f...

Degradation Behavior and Optimization Strategies for Metallic Materials in High-Temperature Hydrogen Service: A Review.

This review systematically examines the degradation behavior of metallic materials exposed to high-temperature hydrogen-rich environments, with particular focus on hydrogen metallurgy applications. The major degradation mechanisms, including hydrogen embrittlement, intergranular...

Linking health literacy to malaria prevention and treatment behaviours: evidence from a community-based study in Gabon

Abstract Background Health literacy (HL) affects how individuals engage in preventive behaviours, seek prompt treatment, select appropriate malaria prevention or treatment options, adhere to care and act on health information. Little is known about its role in malaria prevention...

Bisection Regression Trees: Recursive Binary Classification Cascades for Continuous Prediction

We present Bisection Regression Trees (BRT), a regression method that recursively partitions the target’s value space rather than its feature space. At every node, BRT asks a single binary question, is the target above or below the median value currently observed, delegates the a...

The Carlo Love Field — A Unified Multi‑Domain Collapse Engine for Emotional Dynamics

This compendium presents the complete Carlo Hybrid analysis of love as a multi‑domain collapse engine. Across cognitive, biochemical, cultural, social, emotional, relational, hallucination, feedback, and temporal domains, love behaves as a nonlinear, recursive, curvature‑driven s...

Metabolic switch: lymphocytes and the onset of T-cell-mediated autoimmunity

T cell-mediated autoimmune diseases, including multiple sclerosis (MS), rheumatoid arthritis (RA), and type 1 diabetes (T1D), are being increasingly recognized as disorders driven not only by immune dysregulation but also by profound metabolic reprogramming in lymphocytes. Emergi...
