Scholarship on Chinese popular religion has demonstrated the complex interactions between local cults and Confucian ritual norms and explored multiple historical pathways toward cult standardization or orthodoxification. Less attention, however, has...

Initially considered secure against interception, fiber-optic networks were subsequently found susceptible to covert tapping, although such attacks require different coupling mechanisms and components than those used for twisted pair and coaxial cabl...

In this paper, we deal with a challenging problem in Discrete Geometry. The problem is to maximize the number of halving lines for finite sets in the plane. With respect to this, we improve the lower bounds for the maximum number of halving lines for...

The podocyte is a terminally differentiated cell whose foot processes and slit diaphragm form the final layer of the glomerular filtration barrier. Because podocytes are not effectively replaced after birth, and nephron number is fixed before it, the...

Clear cell renal cell carcinoma (ccRCC) is characterized by loss of the functional von Hippel–Lindau (VHL) complex and distinctive clear cell morphology associated with intracellular glycogen and lipid accumulation. However, the mechanism under...

Designing guided inquiry requires more than reducing teacher direction: open-ended science tasks must preserve learner decision making while providing sufficient support for disciplinary reasoning. Adopting an interpretivist perspective, this qualita...

Ketamine produces rapid antidepressant-like effects across a range of subanesthetic doses, yet how dose shapes behavioral efficacy and region-specific molecular signaling following adolescent chronic unpredictable stress (CUS) is not well understood....

In Assistive technologies, robotics, and automated machines are progressively reshaping the healthcare domain, supporting patients, caregivers, and healthcare professionals across an increasingly broad range of applications [...]

Interferometric measurement of large aperture freeform surfaces often requires sub-aperture stitching to achieve full aperture measurement. We propose layout preselection based on the Hessian response of the design surface to two planar translations...

Background/Objectives: Chronic topical antiglaucoma therapy may affect the ocular surface. We assessed documented dry eye disease (DED) and its associations with active-ingredient burden, treatment duration, and preservative exposure. Methods: This r...

Mullite–alumina composite ceramics were fabricated via in situ reaction sintering by modulating the kaolin-to-calcium phosphate (K/C) mass ratio (3, 6, 9, and 12) within an 80 wt% alumina matrix. The effects of liquid-phase sintering aid conten...

We developed a multiscale numerical model that couples a macroscopic temperature field with a cellular automaton (CA) model to investigate the evolution of the solidification microstructure in the molten pool of Q450NQR1 weathering steel during low-f...

Background: Accurate field triage is a cornerstone of an inclusive trauma system, but pediatric undertriage remains poorly characterized outside North America. We aimed to estimate the rate of major trauma undertriage in a Spanish pediatric trauma ce...

Musculoskeletal injuries are a major occupational health concern in the fire service and can affect firefighter health, operational readiness, staffing, and injury-related costs. Although prior research has described the epidemiology of firefighter i...

Odontogenic sinusitis (ODS) is increasingly recognized as a distinct form of sinonasal disease in which dental and sinus pathology coexist and frequently require coordinated management. Although systemic antibiotics are commonly prescribed, their pre...

Differential interferometric synthetic aperture radar (D-InSAR) provides a potential approach for retrieving mountain snow depth at high spatial resolution using Sentinel-1 interferometric phase information. However, its performance in complex mounta...

Seams in upholstery fabrics are subjected to repeated mechanical loading during use, which may lead to progressive seam opening. This study evaluated a double-pass stitching variant in which the second pass follows the same nominal seam line as the f...

Collision tumors are exceptionally rare. We report here a case of a cutaneous collision tumor composed of metastatic melanoma and small lymphocytic lymphoma (SLL). A 56-year-old man with a prior history of melanoma and chronic lymphocytic leukemia (C...

Maintaining cognitive load that is neither too high nor too low is key for workplace safety and efficiency. Cognitive load assessment research is often conducted in highly controlled laboratory environments that, by nature, come short of fully recrea...

Validation-based rules often decide when synthetic minority augmentation should replace conventional imbalance treatment but may not transfer to new targets. We audited this retrospectively on public Seagate time-series-2 data, whose 11 key quality i...

Background/Objectives: Studies of socioeconomic differences in DNA methylation-based ageing mainly report regression coefficients, group contrasts, mediation estimates, or decompositions, which do not describe how complete epigenetic age acceleration...

Background/Objectives: In patients with suspected acute deep vein thrombosis (DVT), new blood biomarkers with high specificity for DVT could potentially lower the proportion of patients requiring imaging. The plasma microRNAs (miRs) miR-134-5p, miR-1...

Traumatic brain injury (TBI) affects millions of people each year and can lead to persistent neurological disorders, including post-traumatic epilepsy (PTE). Animal models of concussion and TBI, developed since the late nineteenth century, provide a...
