Experimental and molecular simulation study on compatibility and interaction in hybrid plastic–rubber modified asphalt

The application of plastics in asphalt pavements has attracted considerable attention due to its potential environmental and engineering benefits. However, the type and properties of hybrid plastics are critical to the compatibility of modified asphalt. In this study, Rubber–plas...

Production activity and resulting pollution, not depth, driven microbial community structure, function, and assembly mechanisms in an aged petroleum hydrocarbon contaminated soil

The degradation activity of soil microorganisms remains a crucial pathway for the reduction of petroleum hydrocarbons (PHs) pollutants in industrial site soils. Stimulating the metabolic activity of indigenous soil microorganisms to achieve pollutant removal is a promising remedi...

Development of a double-nest droplet digital PCR technology for detection of BVDV and BTV

Bovine viral diarrhea virus (BVDV) and bluetongue virus (BTV) are important pathogens that affect ruminants, they have an overlapping host range, and mixed infections are easily caused in animals under mixed breeding or grazing together. It has always been a hot issue of concern...

Deep-sea Microbial Dataset of the Antarctic Ocean (dsMDAO): A high-resolution deep-sea microbial dataset of the Antarctic Ocean reveals potential for taxonomic and functional diversity

Antarctic deep-sea ecosystems harboured unique and metabolically versatile micro-organisms that sustained key biogeochemical processes under extreme polar conditions. However, the genomic diversity and ecological functions of these sedimentary or deep-sea microbial communities re...

Effects of different fertilization methods on observed oocyte maturity

Abstract Background Conventional in vitro fertilization (IVF) and intracytoplasmic sperm injection (ICSI), are mainstream fertilization strategies for assisted reproduction. Different fertilization strategies adopt distinct timelines for cumulus cell removal and oocyte maturity a...

Deep neural network-driven adaptive fusion recognition method for radar-optical heterogeneous remote sensing imagery

Abstract The fusion of radar and optical remote sensing imagery presents significant challenges due to fundamental differences in imaging mechanisms and feature representations. This paper proposes an adaptive fusion recognition framework based on deep neural networks for heterog...

Biomechanical advantages of the proximal femoral bionic nail with triangular support structure in the treatment of intertrochanteric fractures: a coronal fracture heatmap modeling and finite element comparison of three implant designs

Coronal fracture fragments (CFs) are highly prevalent in intertrochanteric fractures and represent a significant risk factor for internal fixation failure. This study combined anatomical and engineering approaches to construct the first coronal fracture heatmap model and evaluate...

Flood-Induced Shifts in Nitrogen Speciation Alter Nitrogen-Transforming Microbial Communities and Functional Potentials in a Shallow Lake Ecosystem

Nitrogen cycling in freshwater lakes is mediated by diverse microbial communities, yet how nitrogen-transforming communities respond to flood perturbations across multiple habitats remains poorly characterized. In this study, we investigated nitrogen forms and associated microbia...

Optimization of combustion chamber geometry for the improved-double swirl combustion system based on the sensitivity analysis method

Based on the well-established double swirl combustion system (DSCS) for direct-injection diesel engines, a novel improved-double swirl combustion system (I-DSCS) has been proposed. Previous visualization experiment has verified the superiority of the I-DSCS in enhancing impinging...

Association between the preoperative geriatric nutritional risk index and loss of walking independence 180 days after hip fracture surgery: A retrospective cohort study

Abstract Background Malnutrition may impair recovery after hip fracture, but the association between preoperative geriatric nutritional risk index (GNRI) and postoperative walking outcomes remains unclear. We examined the association between GNRI and loss of walking independence...

Chalcogen Bond‐Induced Conformational Locking for Thermoplastic Polyurethane With Superior Puncture Force and Fracture Energy

ABSTRACT A fundamental and long‐standing issue in the design of polymers is how to transcend the constraints of conformational entropy within highly disordered polymer networks, thereby enabling the deterministic orientation of local chemical bonds. While such precision is common...

Evaluation of the efficacy and safety of different cycles of neoadjuvant chemotherapy combined with immunotherapy in locally advanced esophageal squamous cell carcinoma: a multi-center, real-world study

Neoadjuvant chemotherapy combined with immunotherapy (nCIT) can improve radiologic and pathological responses in resectable, locally advanced esophageal squamous cell carcinoma (ESCC), yet the optimal number of preoperative cycles is unknown. We conducted a multicenter, real-worl...

Effectiveness of combined nutrition, exercise and psychological interventions in patients with malignancy: A randomized controlled trial.

BACKGROUND AND OBJECTIVES: Patients with malignancy often have a poor prognosis and dismal quality of life. This study aimed to evaluate whether a combined nutrition, exercise, and psychological intervention could improve these outcomes. METHODS AND STUDY DESIGN: In an open-label...

Construction of a nomogram prediction model for opportunistic sarcopenia in patients with malignant tumors.

BACKGROUND AND OBJECTIVES: The aim of this study was to establish a predictive model for opportunistic sarcopenia applicable to Chinese cancer patients, so as to quickly detect the occurrence of this condition and provide a basis for early clinical intervention. METHODS AND STUDY...
