Asymmetric Alkylation of α-Cyanoketimines with Alkyl Bromides Catalyzed by Bis-Cinchonium Salts

Abstract The SN2 reaction constitutes one of the most fundamental bond-forming transformations in organic chemistry, finding numerous synthetic applications across pharmaceutical, agrochemical, and materials science. However, the development of new catalysts for asymmetric SN2 re...

Argentine Export Tax Variation and Bilateral Agricultural Trade: Evidence on Destination Heterogeneity and Vertical Differentiation

ABSTRACT Argentina applies differentiated export taxes ( retenciones ) on agricultural commodities, and these rates have changed repeatedly since 2010. This article examines the bilateral trade effects of that variation on the taxed commodities, wheat, corn, beef, raw soybeans, s...

‘Super’ El Niño spurs research on ecosystem impacts

This year’s event could shed light on how the natural world may respond to climate change in the decades ahead

Apparent Diffusion Coefficient Composition and Tissue Heterogeneity as Predictors of Functional Outcomes After Endovascular Thrombectomy in Patients With Large Ischemic Core

BACKGROUND: Recent trials established endovascular thrombectomy efficacy in large ischemic cores, yet outcomes remain heterogeneous despite similar infarct volumes, suggesting that current volumetric assessments may not fully capture tissue viability. We examined whether tissue c...

A review of dispersion mechanisms in graphene reinforced ABS nanocomposites for additive manufacturing

Abstract Due to the enhanced mechanical, thermal, electrical, and tribological performance graphene-reinforced Acrylonitrile Butadiene Styrene (ABS) nanocomposites have emerged as promising materials for fused deposition modeling (FDM). However, realizing these improvements remai...

Whole-genome sequencing reveals the genomic epidemiology of Yersinia enterocolitica in South African meat and global populations

Abstract Background Yersinia enterocolitica is a globally distributed foodborne pathogen increasingly recognised within the meat production continuum; however, its genomic epidemiology in South Africa remains poorly characterised. Methods This study employed whole-genome sequenci...

Molecular Epidemiology of Anaplasma capra in Cattle from the Black Sea Region of Türkiye

Anaplasma capra is an emerging tick-borne pathogen with zoonotic potential. Since its first description, the pathogen has been reported in several countries across Asia, Europe, and Africa; however, information on its distribution in Türkiye remains limited. This study investigat...

National statistical organizations at a crossroads: Trust, independence, and democratic relevance in the AI Era

National Statistical Offices (NSOs) were established to serve essential state functions—taxation, mobilization, and administrative governance—but evolved into professional institutions that safeguard the public interest through impartial statistics. Today, despite sustained moder...

Structural analysis and prioritization of e-waste management challenges in the Indian context using ISM and MICMAC methods

E-waste has become one of the critical issues to be addressed in recent years due to ecological and health-related issues. This research intends to investigate these interrelationships among barriers to e-waste management in the Indian context. An exhaustive literature review on...

Spacetime Activation Hypothesis II: Conditions for Relational Records, Clock Scales, and Inheritance(時空起動仮説Ⅱ――関係記録・時計尺度・継承の成立条件)

This integrated preprint examines the distinct conditions for preserving information, reading relational records, calibrating clock scales, and inheriting records through changes of form. It brings together Parts I–III and Supplement A of Spacetime Activation Hypothesis II. A des...

Sediment and bedload continuum at alpine hydropower plants – case studies from Tyrol (Austria) and suggestions for monitoring and management

TIWAG is operating 10 large (>10 MW) and 26 small (<10 MW) hydropower plants, with an installed capacity of about 1,650 MW and a mean annual production of 3,400 GWh. Long-term monitoring reveals insights into suspended sediment loads as well as bedload transport. This includes ab...

Ultrasound-Assisted Deep Eutectic Solvent Extraction of Total Flavonoids from Hainan Li-Medicine Polygonum hydropiper: Process Optimization, Antioxidant Activity and Molecular Mechanism

Ultrasound-assisted deep eutectic solvent (DES) extraction was developed for the efficient recovery of total flavonoids from Polygonum hydropiper L., a traditional Li medicinal plant from Hainan, China. Among 30 DES formulations screened, betaine-glycerol (Bet-Gly, 1:2) afforded...

Rewiring Food Allergy Management: From Allergen Detection to Immune Engineering Therapies

BACKGROUND: Food allergy represents a growing global health challenge, particularly among children in developed countries. Despite decades of research, major barriers persist in both allergen detection and durable immune intervention. METHODS: This review synthesizes current diag...

AI-driven mobile practice and English-speaking performance: a quasi-experimental study of ELSA speak among Malaysian university learners

This study examined whether supplementary use of the AI-enabled ELSA Speak application was associated with improved English-speaking performance among Malaysian university learners. A mixed-methods, quasi-experimental pre-test–post-test non-equivalent control-group design involve...

Efficient Offline Policy Optimization under All-Policy Linear Q-Realizability

We study offline policy optimization in finite-horizon Markov decision processes with a finite action set and a known bounded feature map. We assume that the action-value function of every randomized memoryless policy is exactly linear, with coefficient norm at most B, and that t...

Valorization of Invasive Faxonius limosus Shell Waste as a Biosorbent for Zn(II) and Cd(II) Removal from Aqueous Solutions

The increasing contamination of aquatic environments by heavy metals and the need for sustainable management of invasive aquatic species have stimulated interest in low-cost biosorbents derived from biological waste. In this study, minimally processed shells of the invasive crayf...

Hierarchical Regime-Conditioned Ornstein–Uhlenbeck Monitoring for Thermal Control in Memory Reliability Test Equipment

Burn-in fixtures for memory packages log the chamber temperature every second, but the logs contain no fault labels, the sensor resolution is comparable to the noise, and normal behaviour depends on both the operating regime and the individual fixture; a regime-blind reconstructi...

Sodium–Glucose Cotransporter 2-Mediated Glucose Uptake Contributes to Glycogen Accumulation in Clear Cell Renal Cell Carcinoma: Implications for Clear Cell Morphology and Potential Therapeutic Relevance

Clear cell renal cell carcinoma (ccRCC) is characterized by loss of the functional von Hippel–Lindau (VHL) complex and distinctive clear cell morphology associated with intracellular glycogen and lipid accumulation. However, the mechanism underlying glycogen storage remains uncle...

Differences in Occupational and Health Accommodations for Older Workers by Workplace Size: A Text Mining Analysis of Open-Ended Responses

Abstract Objectives As labor force participation among older workers continues to increase, the nature of workplace accommodations may vary according to workplace size. In this study, we aimed to clarify the current status and characteristics of workplace accommodations that addr...
