Drought stress constitutes a persistent constraint on tree survival, and larch, owing to their distinctive needle morphology, deploys drought-responsive strategies that differ from those of broad-leaved trees. In this study, we identified a putative...

In cementing operation, the “cement-–rock” interface bonding ability is an important factor affecting the long-term sealing ability of cement sheath, and the evolution mechanism of the interface sealing ability needs to be further s...

A cell $(i,j)$ of a Young diagram is called an inner cell if all four of its neighbours $(i\pm 1,j)$ and $(i,j\pm 1)$ also belong to the diagram. A standard Young tableau (SYT) of a hollow shape is one whose Young diagram contains no inner cells. I...

Background: Respiratory syncytial virus (RSV) has emerged as a major cause of hospitalization among adults in the post-pandemic era. We studied the epidemiological findings and the outcomes of patients hospitalized with influenza or RSV during the fi...

Given its large range and spatial footprint, radar remote sensing has been met with increased interest in the wind energy community. Paired radars can yield complete wind speed and direction measurements over this large spatial footprint, an invaluab...

Background/Objectives: Accurate three-dimensional (3D) assessment of glenoid morphology depends on the coordinate system used for measurement. Conventional landmark-based coordinate systems may be affected by observer-dependent variability in identif...

Background: Electroencephalogram (EEG) signals provide important information for brain–computer interfaces (BCIs) and the diagnosis of neurological disorders but are susceptible to electrooculographic (EOG) artifacts. Traditional methods often...

Bougainvillea (Nyctaginaceae) cultivars are horticulturally prized worldwide for their vivid bracts; however, repeated interspecific hybridization and somatic mutations have obscured their maternal origins, particularly for double-bracted forms. Here...

Background/Objectives: Preoperative recognition of complicated acute appendicitis remains difficult, although severity influences treatment and perioperative planning. This study examined clinical and laboratory correlates of histopathologically comp...

To address the loss of local defect information, insufficient adaptation to irregular defect patterns, and background interference in transmission-line insulator inspection, this paper proposes DRB-DEIM, a text-guided and orientation-aware multiscale...
