Comparative efficacy of two novel bioceramic root canal sealers in the treatment of chronic apical periodontitis

Chronic apical periodontitis (CAP) is a persistent periradicular inflammatory condition driven by intraradicular infection and remains a common indication for primary nonsurgical root canal therapy. This retrospective cohort study compared 2 calcium silicate-based bioceramic root...

Multitarget Dynamic Action Recognition Model for Construction Workers Based on Continuous Action Features

Abstract To address the current problems of frequent injury accidents among construction workers, imperfect supervision systems, and low adaptability of existing algorithms, a dynamic action recognition model for construction workers based on continuous action features and a diff...

Surface Potential Well‐Gated Piezocarrier Escape for Reversible Oxygen Redox in Lithium–Oxygen Chemistry

ABSTRACT Piezocatalysis offers a promising way to harness intrinsic mechanical energy for accelerating sluggish oxygen redox reactions in lithium–oxygen batteries. However, its efficiency depends not just on piezoelectric polarization strength, but critically on whether stress‐in...

Flood damage estimation and disaster perception using multi-source data: a case study of Henan, China

Urban flood is becoming increasingly frequent worldwide, posing a serious threat to life and property. Accurately assessing flood damage is critical for risk management and flood prevention. However, traditional estimation methods are resource-intensive and untimely. Previous stu...

Integrated lncRNA and mRNA Transcriptome Analysis Reveals Candidate Regulatory Networks Associated with Postnatal Longissimus Dorsi Muscle Development in Hanper Sheep

Skeletal muscle development is a key determinant of meat production and meat-quality traits in sheep, but the coordinated long non-coding RNA (lncRNA) and messenger RNA (mRNA) co-expression landscape underlying postnatal muscle development in Hanper sheep remains unclear. In this...

Adaptive multi-objective model predictive trajectory tracking control of 4WID-4WIS AEVs

Distributed-drive autonomous electric vehicles have significant potential to enhance vehicle safety and efficiency through their superior control flexibility. However, their over-actuation inevitably increases control complexity, making it challenging to balance high-precision tr...

Physics-Informed Neural Networks for One-Dimensional Groundwater Contaminant Transport: A Synthetic Numerical Study of Prediction and Parameter Inversion

This study developed a physics-informed neural network (PINN) surrogate model for a one-dimensional synthetic groundwater contaminant-transport problem with adsorption, using Crank–Nicolson numerical solutions as the reference data. The effects of observation density and noise on...

The characteristic analysis and pattern classification of Beijing’s commercial districts based on multi-source geographical big data

Abstract Commercial districts, as key hubs for diverse commercial activities, play a crucial role in urban life. Yet in recent years, the vitality of commercial districts is declining. Although various strategies for revitalizing commercial districts have been proposed, it’s esse...

An ABA /auxin regulatory module controlled by nitrogen governs symbiotic organogenesis in the bryophyte species Ricciocarpos natans

Summary During the terrestrialization of plants c. 470 Ma, overcoming nitrogen limitation was a major evolutionary challenge. While nonvascular plants may acquire nitrogen through rhizoids and surface diffusion, symbiotic interactions likely provide an important strategy to overc...

Early Compound Nutritional Intervention Improves Hair Follicle Development in Northwest Xizang White Cashmere Goats: An Analysis Based on Skin Multi-Omics

The Northwest Xizang White Cashmere goat has a high global reputation for good goat cashmere germplasm characteristics, and its cashmere industry is the economic pillar of the herdsmen in the northwest plateau of Xizang. Cashmere is produced by the secondary hair follicles of the...

Association between the number of missing/replaced teeth and Chronic Kidney Disease (CKD): cross-sectional analysis of NHANES data

This study aimed to investigate the association between the number of missing/replaced teeth and chronic kidney disease (CKD), and whether there is a dose-response relationship with markers of renal function. Utilizing data from the National Health and Nutrition Examination Surve...

pH responsive nanoplatforms for radiosensitization and radioprotection in cancer therapy

Radiotherapy remains a cornerstone of cancer treatment, but its efficacy is limited by tumor hypoxia, adaptive antioxidant defenses, and the resulting radioresistance. Tumor extracellular acidity, commonly reported within an approximate pH range of 6.5–7.1, contributes to invasio...

Integrated analysis of surface water-groundwater interactions and enhanced hydrological forecasting of glacierized river in cold and arid regions

Abstract In cold and arid regions, climate change has altered precipitation patterns and accelerated glacierized retreat, which imposes severe risks on the stability of regional hydrological systems. Combined with the strong interactions between surface water (SW) and groundwater...

The diagnostic and prognostic value of serum FBXO11 expression in neonatal sepsis

This study aimed to investigate the correlation between serum FBXO11 expression and serum PCT and CRP levels as well as its diagnostic and prognostic value in neonatal sepsis (NS). This study included 120 patients with NS aged ≤ 28 days, birth weight > 2500 g, and gestational age...

High-Precision UT1 Prediction with Different Angular Momentum Combination Schemes

Universal Time (UT1) is a core component of the Earth orientation parameters (EOP). High-precision UT1 predictions are essential for satellite navigation, deep-space exploration, and the maintenance of national standard time. Although effective angular momentum (EAM) information...

Akkermansia muciniphila attenuates Brucella infection: TLR4−associated inflammatory regulation and gut microbiota remodeling
