This paper systematically studies a space-fractional variable-coefficient Toda (sfvToda) lattice equation. The core innovation of this paper lies in incorporating both fractional power of the recursion operator and time-varying coefficients into the...

Rapid technological iteration has turned electric vehicle (EV) purchasing into a decision about timing: buy now, or wait for a better model. Prior research explains how favorably consumers evaluate EVs, but not when they intend to buy. It also treats...

Surrogate models can reproduce wastewater effluent trajectories accurately, but their use in optimization also requires a suitable representation of the response to control actions. This paper proposes an actionability-aware framework for assessing a...

Although vital to urban operations, urban freight transport (UFT) generates substantial negative externalities. Despite the rising interest in urban transport sustainability, methodological frameworks targeting UFT remain scarce, particularly those t...

Bacteriophage vB_SalS_KY05 (KY05) was propagated using a non-pathogenic E. coli K-12 strain. The lysate was administered via water for 56 days. Thirty Lohmann Brown-Classic laying hens (53 weeks old) were randomly assigned to three groups: the Contro...

Background/Objectives: Procalcitonin has been proposed as an alternative or complementary biomarker to calcitonin in medullary thyroid carcinoma (MTC). We synthesised the published systematic reviews, appraised their quality, and measured their relia...

Bone tissue regeneration remains a major clinical challenge, and exosomes secreted by mesenchymal stem cells (MSCs) have emerged as attractive cell-free therapeutic tools. To enhance their efficacy and local action, exosomes can be modified to enrich...

The adoption of virtual reality (VR) in higher education depends partly on how usable and acceptable VR resources are perceived to be. This two-phase study evaluated a 360° VR learning object about women scientists commemorated in the street name...

Indoor millimeter-wave Internet of Things (IoT) terminals are constrained by limited computing capability and energy, while blockage can severely degrade the uplinks required for computation offloading. This paper investigates a pinching-antenna syst...

Phytases are industrial enzymes that enhance the availability of phytate-bound phosphorus and can reduce the environmental burden associated with undigested phytate. Bacillus paralicheniformis T7 is a spore-forming strain exhibiting multiple hydrolyt...

Indoor navigation is fundamental to autonomous mobile robots (AMRs), yet the relationships between explicit planning, learned policies, and large model-based decision-making remain difficult to assess across heterogeneous experiments. This review est...

Background/Objectives: The concurrent occurrence of papillary (PTC) and medullary (MTC) thyroid carcinoma within the same thyroid gland is an exceptionally rare clinical entity. We conducted a systematic review to synthesize available evidence on the...

The phase-out of high-GWP refrigerants means working fluids are increasingly replaced in compressors already designed and sized for the original fluid. Assessing the fluid replacement in a fixed geometry is complicated by the choice of operating para...

Under the dual challenges of frequent disruption risks in global supply chains and the sustainable transformation of enterprises, this paper, based on the data of Chinese A-share listed companies from 2002 to 2023, systematically analyzes the mechani...

The effectiveness of open data visualization systems depends on their usability and accessibility, two attributes that are rarely examined in depth. This study examined how the administrators of 12 such systems in Colombia perceive and evaluate both,...

Background: Prenatal attachment—the bond a pregnant woman forms with her unborn child—has been associated with postpartum bonding and infant development, yet its predictors among first-time pregnant adolescents remain unclear. Methods: Th...

Grippers are extremely important in robotics. Conventional grippers are composed of rigid components, but soft grippers made of soft materials have also gained considerable attention. Most grippers require actuators such as electrical motors and pneu...

The monomiality principle provides an algebraic framework in which polynomial families can be treated operationally as ordinary monomials, with the Heisenberg–Weyl algebra underlying the corresponding raising and lowering operators. Legendre po...

To clarify the responses of tomato stem sap flow to soil water availability and microclimate in an extremely arid region, three irrigation treatments were established in an overwintering solar greenhouse in Kashgar, Xinjiang. The soil at the experime...

Background: Clinical responses to first-generation mechanistic target of rapamycin (mTOR) inhibitors vary substantially across malignancies, indicating that pathway activation alone is insufficient to identify tumors likely to depend on mTOR signalin...

Acinetobacter baumannii (AB) is recognized as a major opportunistic nosocomial pathogen. Its success largely depends on the ability to adhere to and colonize both biotic and abiotic surfaces, survive under adverse environmental conditions, and acquir...

Gameful digital mental health interventions are increasingly used to support university students, but evidence for the effectiveness of complete intervention packages should be distinguished from evidence that specific game mechanics independently im...
