Under study was the effect of the energy density and pulse duration of laser radiation on metastasization of Lewis carcinoma and melanoma B16. It was shown that laser irradiation of blastomas, the energy density of the former not exceeding 400 joule/cm2 and the pulse duration being 1 msec, not only fails to contribute to tumor proliferation but, on the contrary, somewhat reduces the number of pulmonary metastases. The phenomenon of such kind is observed in simultaneous rise of the energy density up to 800 joule/cm2 and lengthening of the pulse up to 6 msec.

Large herbivores are in decline in much of the world, including sub-Saharan Africa, and true apex carnivores like the lion () decline in parallel with their prey. As a consequence, competitively subordinate carnivores like the African wild dog () are simultaneously experiencing a costly reduction in resources and a beneficial reduction in dominant competitors. The net effect is not intuitively obvious, but wild dogs' density, survival, and reproduction are all low in areas that are strongly affected by prey depletion.

The socioeconomic burden of hip fractures, the most severe osteoporotic fracture outcome, is increasing and the current clinical risk assessment lacks sensitivity. This study aimed to develop a method for improved prediction of hip fracture by incorporating measurements of bone microstructure and composition derived from high-resolution peripheral quantitative computed tomography (HR-pQCT). In a prospective cohort study of 3028 community-dwelling women aged 75 to 80, all participants answered questionnaires and underwent baseline examinations of anthropometrics and bone by dual x-ray absorptiometry (DXA) and HR-pQCT.

DXA can also assess hip geometry, including femoral neck width (FNW) and hip axis length (HAL), which have both been associated with increased risk for hip fracture independently from BMD. Our objective was to assess if FNW predicts hip fracture independently from other factors including HAL.

This study tried to focus on the older drivers' group and explore the impact factors of injury severity involving older drivers from geo-spatial analysis. To reach the goal, a spatial analysis was proposed employing geographic information systems (GIS) with a case study application to two counties in Nevada. First, crash clusters were explored using Density-Based Spatial Clustering of Applications with Noise (DBSCAN) approach to investigate the spatial crash pattern for older drivers, and determine high risk locations of injury severity.

We investigate the superconducting instabilities of twisted bilayer graphene quasicrystals (TBGQCs) obtained by stacking two monolayer graphene sheets with 30° relative twisting. The electronic energy spectrum of the TBGQC contains periodic energy ranges (PERs) and quasiperiodic energy ranges (QERs), where the underlying local density of states (LDOS) exhibits periodic and quasiperiodic distribution, respectively. We found that superconductivity in the PER is a simple superposition of two monolayer superconductors.
