Abstract The singularity problem brings troubles to the design and application for the parallel mechanism. Currently, redundant actuation is one of the useful methods to solve this singularity problem. However, faced to ...

Histidine kinases (HKs) are a central part of bacterial environmental-sensing two-component systems. They provide their hosts with the ability to respond to a wide range of physical and chemical signals. HKs are multidom...

Non-infectious uveitis encompasses a diverse array of autoimmune ocular disorders marked by the breakdown of immune tolerance and recurrent inflammatory episodes. Regulatory T cells (Tregs) are integral to the maintenanc...

Abstract Objectives: Patients with post-traumatic stress disorder (PTSD) present a variety of symptoms, with different intensities, causing impairment in individual, social, and occupational functioning. The aim of this...

Liver and kidney, as the core metabolic detoxification organs of human body, rely on specific biofilm barrier and metabolic enzyme system to form metabolic barrier respectively. This metabolic barrier is the key defense ...

Abstract To improve sketch recognition accuracy, this study proposes an enhanced sketch recognition model based on an improved CycleGAN network and a dual attention mechanism. The proposed model first incorporates multi-...

Abstract Yunkai area is located in the southwest of South China Block and is characterized by widespread granite distribution, dense hot spring occurrences, and well-developed deep faults, indicating significant geotherm...

Direct Cash Assistance (BLT) is a government program aimed at helping households meet basic needs and improve financial resilience, especially for low-income communities. This study aims to analyze the effect of the amou...

Abstract: The assessment process is a fundamental aspect of the educational system, playing a pivotal role in shaping both student development and educational outcomes. In this regard, the Algerian education system ha...

Di(2-ethylhexyl) phthalate (DEHP) is a commonly used plasticizer that has raised significant concerns due to its strong endocrine-disrupting effects, which are closely associated with developmental toxicity. While previo...

Abstract Graphene has superhigh thermal conductivity up to 5000 W/(m·K), extremely thin thickness, superhigh mechanical strength and nano-lamellar structure with low interlayer shear strength, making it possess great po...

The traditional failure mechanisms with constant shapes usually overestimate the basal stability of excavations in clay. A new mechanism is established based on the upper bound theorem. The least upper bound solutions an...

2012 election, which took place under exceptional political auspices, is generally considered atypical when compared to the other five post-communist local election cycles, the two reasons for this being the increased ci...

Background and aims Meat-borne Staphylococcus aureus (S. aureus) remains a leading global foodborne pathogen harbouring novel enterotoxin genes (NEGs) encoding superantigenic toxins with conditionally enhanced pathogenic...

In the digital age, authentication is essential for accessing the web and mobile platforms, yet many mechanisms still overlook the accessibility challenges faced by people with disabilities. In this work, a systematic li...

Plants are sophisticated and intelligent natural construction materials. They can be used for enhancing the stability of shallow soil slopes and minimizing surface erosion. It is evident that the use of plants can be low...

Abstract The current research of abrasive belt grinding rail mainly focuses on the contact mechanism and structural design. Compared with the closed structure abrasive belt grinding, open-structured abrasive belt grindin...

Type Ia supernovae (SNe) occur when a white dwarf (WD) explodes via runaway thermonuclear burning. To date, major uncertainties remain regarding the nature of the explosion mechanism and its observable signatures. In thi...

Background. Depression is one of the most common mental disorders worldwide and a significant public health concern. In elite athletes, particular attention has been given to the transition period following career termi...

Abstract The formation of a precursor film (PF) is always coupled with better wettability; thus, clarifying the formation mechanism is required to optimize the interfacial structures. However, recent research focuses on ...

Abstract The additive manufacturing of continuous fiber composites has the advantage of a high-precision and efficient forming process, which can realize the lightweight and integrated manufacturing of complex structures...

KH2PO4—cement is used to soildify/stabilize the Pb contaminated soil. Leaching tests are conducted to study the leaching characteristics and mechanism of Pb in solidified bodies under acid rain soaking, and the effects...

Partially clonal plants are common and often act as ecological foundation species. Patterns of clonal genotypes (genets) and their vegetative modules (ramets) in natural populations remain poorly documented. Knowledge ga...

Smilax glabra, a perennial vine with high pharmaceutical value, exhibits seed dormancy under natural conditions that severely restricts artificial propagation and industrial-scale cultivation. This study aims to systemat...
