POPs Contamination of Aquatic Sediments of the Cerna River Watershed, Romania—Prevalence, Pollution Sources, and Ecological Risk Assessment

This study aims to evaluate the prevalence and pollution sources of polycyclic aromatic hydrocarbons (PAHs), polychlorinated biphenyls (PCBs), and organochlorine pesticides (OCPs) in sediments of the Cerna River and its main tributaries, and to assess the associated ecological ri...

Microstructure and Non-Metallic Inclusion Modification in Steel Deoxidized by Complex Fe-Si-Mn-Al Alloy

This study evaluates the effects of semi-industrial and synthetic Fe–Si–Mn–Al deoxidizers on the microstructure, non-metallic inclusions, and hardness of St3 steel. Seven complex alloys with different Fe, Si, Mn, and Al contents were produced and compared with conventional FeSi–F...

Some remarks on closed $$\rho $$-Einstein solitons

Abstract This work shows that, under natural conditions, every closed soliton of the Ricci–Bourguignon flow has constant scalar curvature. In addition, we present alternative proofs of certain results on triviality.

Single-cell Transcriptomics in Autoimmune Diseases: Mechanistic Insights, Cross-disease Convergence, and Translational Challenges in Rheumatoid Arthritis, Systemic Lupus Erythematosus, Type 1 Diabetes, and Multiple Sclerosis

Abstract Autoimmune diseases are characterized by loss of immune tolerance and substantial heterogeneity across patients, tissues, and disease stages. Although bulk transcriptomic studies have identified important inflammatory pathways, they cannot directly resolve rare, transiti...

Interfacial Charge Regulation in Hollow CuFe2O4/Bi4O5Br2 Heterostructures for Ultrasensitive Photoelectrochemical Detection of Oxytetracycline

Abstract Antibiotic residues are increasingly being regarded as the emerging pollutants worthy of attention. Here, a hollow CuFe2O4/Bi4O5Br2 heterostructure was engineered as an aptamer-free photoactive interface for the highly sensitive determination of oxytetracycline. The hier...

Fibro-Adipogenic Progenitor-Derived Pentraxin 3 Promotes Porcine Slow-Twitch Myofiber Formation by Suppressing the TLR4/TGFβ/SMAD2/3 Signaling Pathway

Abstract Skeletal muscle fiber-type composition is a critical factor influencing pork quality. However, the key proteins governing muscle fiber-type transformation remain largely unclear. Here, we define the secreted protein landscape underlying muscle fiber-type transformation r...

The Fragile Coupon Collector: Random Deadlines, Critical Fragility, and Optimal Sampling

We study coupon collection when each type is at risk of disappearing until its first observation, after which it becomes permanently safe. Sampling follows a fixed independent and identically distributed law. For uniform sampling and common fragility, the success probability is t...

Plantar Eczema Treated with Individualized Homeopathic Medicine: A Case Report

Abstract Eczema is a chronic relapsing inflammatory skin disease that affects children and adults, and is characterized by symptoms such as itching, redness, oozing of discharge, and scaly patches. It has a considerable socioeconomic burden with varying degree of severity leading...

Development of novel dental composites integrated with MSN–TQ systems

Thymoquinone (TQ), recognized for its potent antibacterial capabilities, is a promising compound for both preventive and therapeutic applications in various diseases. In this study, TQ molecules were successfully loaded onto biocompatible, easily synthesized, and cost-effective M...

Orch-OR Theory: Speculative Quantum Gravity Framework Lacking New Evidence — E8 Intelligence Research

FINDING: Orch-OR theory remains a speculative framework linking quantum gravity (objective reduction) to microtubule dynamics; no new mathematical formalism or experimental evidence is presented in these sources — they are primarily expository videos and one unrelated clinical QA...

Rethinking the creative city in post-conflict historic cities: a scoping review and critical planning framework

Purpose The global Creative City paradigm, which is based on stable governance and market-driven growth, fails in the fragmented, traumatic conditions of post-conflict historic cities. This scoping review demonstrates the necessity of critically reinventing this paradigm for cont...

Acute Alcohol-Associated Hepatitis: The Role of Liver Transplantation

Severe alcohol-associated hepatitis (AH) remains one of the most challenging syndromes in hepatology and critical care, with high short-term mortality despite advances in supportive management. Although corticosteroids remain the only guideline-endorsed pharmacologic therapy show...

Investigating the role of previously acquired languages in L3 semantic access through long-term crosslanguage repetition priming

The study's aim was to examine how learners with different L3 proficiency levels access the conceptual representations of L3 Spanish words through their previously acquired languages. To do so, a long-term crosslanguage repetition priming task was administered. During the encodin...

Cyclic symmetry and the Hodge conjecture for the fourfolds F(x)+F(y)=0

For a ternary form F of degree d with smooth zero locus C_F, we study the fourfold X_F given by F(x) + F(y) = 0 in ℙ^5 and the surface Y_F given by F(x) + u^d = 0, the cyclic cover of the plane branched along C_F. Here F is very general among the forms invariant under a cyclic sy...

From Molecular Design to In Vivo Validation: Integrated Efficacy and Safety Profiling of Orotic Acid–1,2,4-Triazole Hybrids with Wound-Healing Activity

Chronic and difficult-to-heal wounds require topical agents that combine reparative activity with favorable local disposition and an acceptable preliminary safety profile. This study evaluated three orotic acid–1,2,4-triazole hybrids (1–3) using an integrated computational and ex...

Triple-Emission Lanthanide Metal−Organic Framework for Crosstalk-Free and Dual-Ratiometric Simultaneous Sensing of Copper(II) and Nitrite

Abstract Copper ions (Cu2+) and nitrite (NO2−) are two prevalent pollutants in aquatic environments that frequently coexist and potentially exert synergistic toxic effects. However, the simultaneous and precise quantification of these two species remains a formidable challenge du...

IoT-Enabled Hybrid Wiper and Micro-Mist Spray System for Autonomous Solar Panel Cleaning: A Rain-Aware ESP32 Prototype to Recover Soiling Losses While Reducing Water Use

This research paper presents the design and prototype of an IoT-enabled hybrid wiper and micro-mist spray system for autonomous solar panel cleaning. The proposed system uses an ESP32 microcontroller and a rain sensor to monitor wet and dry conditions and control the cleaning cyc...

Quantifying Geographic Domain Shift to Decouple the Geospatial Transferability of Human Mobility Flow Generations

Human mobility serves as an essential proxy for understanding social, economic, and environmental dynamics in urban systems. However, since human mobility data are often scarce due to high collection costs and privacy concerns, generating them from limited mobility observations o...

Salt Dissolution–Induced Permeability Enhancement and Its Implications for Improved Oil Recovery During Waterflooding in Saline Lacustrine Carbonate Reservoirs

Waterflooding in saline lacustrine carbonate reservoirs frequently induces dissolution of soluble salt minerals, a process that substantially alters pore architecture and transport properties. However, the quantitative relationship between salt dissolution, permeability evolution...

The anatomy of hitting: assessing age-related changes in MLB performance via layered Dirichlet modeling

Abstract The productive career of a professional athlete is short relative to the human lifespan, with most Major League Baseball (MLB) players retiring by age 40. Although younger players often possess superior physical tools, older players may differ in the composition of plate...
