Single-vacancy engineering of blue phosphorene for suppressing the shuttle effect and enhancing conversion kinetics in Na-Se batteries: A computational investigation

The development of high-performance sodium-selenium (Na-Se) batteries is critically hindered by the dissolution and migration of intermediate polyselenide species, which induce severe shuttle effects and degrade cycling stability. In this work, first-principles density functional...

Anatomical and histological changes associated with hibernation in the stomachs of Anatolian ground squirrels

This study investigated the anatomical and histological characteristics of the stomach in Anatolian ground squirrels ( Spermophilus xanthoprymnus ) during hibernation (H) and non-hibernation (NH) periods. Stomach tissues from hibernating and non-hibernating animals were examined...

Role of digitalization and environmental policy stringency in the relationship between financial development and environmental sustainability

Financial development is often viewed as a cornerstone of economic progress, yet its expansion may come with an environmental cost. This raises a critical question of whether digitalization and environmental policy stringency can weaken the link between financial development and...

A review on the recent trends in solar-biomass hybrid drying of agro and marine products in the context of sustainable development goals

Post-harvest losses remain a critical challenge in global food systems, pressing the need for efficient and sustainable drying technologies to ensure food preservation and food loss reduction. The primary objective of this review is to study solar hybrid drying (SHD) systems with...

Optimized Efficiency to Minimize Transmission Losses and Reduce Overall System Operating Costs of 1100 kV Converter Transformers for Power Transmission System

Abstract Converter transformers are the largest single source of controllable loss in a line-commutated ultra-high-voltage direct-current (UHVDC) converter station, yet they are usually specified with loss-capitalization rules developed for sinusoidally loaded power transformers....

Enhanced antimicrobial activities of nicotine-enriched hydrothermal liquids from tobacco wastes

Hydrothermal carbonization (HTC) offers a promising pathway to convert alkaloid-rich tobacco wastes into functional carbon materials and bioactive liquids. However, the release behavior of nicotine during HTC and the relationship between nicotine occurrence and the antimicrobial...

The role of parkland agroforestry tree species for soil physicochemical properties and crop productivity in Hirna and Kersa, Eastern Ethiopia

Scattered parkland agroforestry trees play an important role in sustaining soil fertility and crop productivity in smallholder farming systems, yet quantitative evidence from eastern Ethiopia remains limited. This study evaluated the effects of Acacia albida, Cordia africana, and...

Effects of laparoscopic radiofrequency ablation combined with a levonorgestrel-releasing intrauterine system in patients with adenomyosis

To compare the 12-month clinical outcomes of laparoscopic RFA alone with those of laparoscopic RFA combined with LNG-IUS in patients with symptomatic adenomyosis. This single-center retrospective cohort study included 70 patients with adenomyosis who had complete 12-month follow-...

Engineering high-performance magnetic biochar for efficient tetracycline capture

Upcycling Chinese herbal medicine residues (CHMRs) into functional biochar adsorbents for treating antibiotic-contaminated wastewater aligns with the development philosophy of “using waste to reduce waste.” To address the challenges of easy agglomeration and limited pore developm...

Attention-Guided Efficient Structure Reassembly Through Reverse Contribution-Driven Feature Distillation and Inconsistency-Resilient Sample Filtering

Excessive features and/or inconsistent samples in practical complex system modeling often misguide decision-makers’ attention. To address this challenge, a novel attention-guided efficient structure reassembly approach is proposed through reverse contribution-driven feature disti...

Semi-analytical modeling and experimental measurement of elastic thermal expansion and aspect-ratio effects in Cu/SiO2 vias for 3D IC integration

Thermally induced protrusion of Cu pads embedded in SiO 2 vias is important for fine-pitch Cu/SiO 2 hybrid bonding, but its dependence on via geometry remains incompletely quantified. In this work, in situ heating atomic force microscopy (AFM) measurements at 25 and 200 °C are co...

VLM-Mapper: Multimodal vision-language models for prior guided lane-level HD map construction

The automated construction of High-Definition (HD) maps from remote sensing data is essential for modern intelligent transportation systems and spatial data infrastructure. While imagery provides a scalable solution for lane-level HD map construction, traditional discriminative m...

HPV vaccine uptake and barriers among adolescent girls and young women living in the urban slums of Kampala, Uganda

A high incidence of cervical cancer is evident in several low-income countries, particularly in the urban slums that harbor densely populated poor communities. Even though Human papillomavirus (HPV) vaccination is a key strategy for cervical cancer, the uptake remains low in thes...

X-Linked Agammaglobulinemia with De novo BTK Mutations in Chinese Children: A Case Report and Literature Review

X-linked agammaglobulinemia (XLA) is a rare primary immunodeficiency caused by Bruton’s tyrosine kinase ( BTK ) mutations that lead to defective B-cell development and severe antibody deficiency. This study aimed to describe a novel de novo BTK mutation in a Chinese child and sum...

Molecular-dynamics simulations of void formation in Si wafer during stealth dicing processes

Stealth dicing is a process used in semiconductor manufacturing to cut wafers into individual chips. It involves focusing a laser beam inside a silicon wafer to produce a modified layer, which is then subjected to an external force. The modified layer consists of regions with hig...

Cohort classification methods shape the interpretation of tree growth responses to harvesting: evidence from a natural mixed forest

Cohort classification is fundamental to interpreting tree growth responses to silvicultural interventions, yet whether the choice of classification method shapes these interpretations remains untested in structurally complex natural forests. We compared five cohort classification...

A global spatiotemporal ionospheric prediction model based on a time–frequency mixture-of-experts mechanism

Spatiotemporal Observer (ST-Observer) is a recently proposed spatiotemporal prediction framework grounded in dynamical system theory, which outperforms many spatiotemporal prediction models on three publicly available datasets. However, through careful analysis, we found that its...

FramePoison: attacks on medical RAG that target framing, not just facts

Retrieval-augmented generation (RAG) is increasingly used in high-stakes domains like medicine, where answers are grounded in retrieved literature and can shape clinical understanding. This opens a new attack surface: an adversary can shape model outputs by injecting a few docume...

Redefining fuel poverty: Introducing the temporal equity framework (TEF)

The definition and quantification of fuel (or energy) poverty remain contentious, particularly within the English policy landscape. The current official definition—Low Income Low Energy Efficiency (LILEE)—systematically underestimates the condition in low- and middle-income house...

Freeze–thaw cycles alter soil pore-size distribution and enhance soil water accumulation under no–tillage on the Loess Plateau

No-tillage (NT) has frequently been reported to increase the risk of soil compaction while enhancing soil water content. In cold regions, freeze-thaw cycles (FTC) strongly influence soil structure and hydrothermal regimes. However, it remains unclear whether FTC can effectively i...
