The size of the functional base of support decreases with age

open access: greenScientific Reports
Falls occur more often as we age. To identify people at risk of falling, balance analysis requires an accurate base-of-support model. We previously developed a functional base-of-support (fBOS) model for standing young adults and showed that its area is ...

Size-dependent strong metal-support interaction in TiO2 supported Au nanocatalysts [PDF]

open access: yesNature Communications, 2020
Strong metal-support interaction (SMSI) is critical in determining the catalytic performance of supported metal catalysts. Here the authors report a phenomenon of size-dependent classical SMSI in Au/TiO2 catalyst where larger Au particles are more prone ...

Support vector regression algorithm modeling to predict the parturition date of small - to medium-sized dogs using maternal weight and fetal biparietal diameter [PDF]

open access: yesVeterinary World, 2021
Background and Aim: Fetal biparietal diameter (BPD) is a feasible parameter to predict canine parturition date due to its inverted correlation with days before parturition (DBP).

Genomic insights into body size evolution in Carnivora support Peto’s paradox

open access: yesBMC Genomics, 2021
Background The range of body sizes in Carnivora is unparalleled in any other mammalian order—the heaviest species is 130,000 times heavier than the lightest and the longest species is 50 times longer than the shortest.

Size exclusion chromatography as green support for forced degradation study of adalimumab

open access: yesActa Pharmaceutica, 2023
Size exclusion chromatography (SEC) has become a powerful tool for analysing size variants of biologic drugs in their native form. Modern SEC can be defined by the use of chromatographic columns packed with sub-3 µm particles, allowing an increase in ...

Changes in structure and function of social networks of independently living middle-aged and older adults in diverse sociodemographic subgroups during the COVID-19 pandemic: a longitudinal study

open access: yesBMC Public Health, 2022
Background Social networks, i.e., all social relationships that people have, contribute to well-being and health. Governmental measures against COVID-19 were explicitly aimed to decrease physical social contact.

Purification and electron cryomicroscopy of coronavirus particles. [PDF]

open access: yes, 2008
Intact, enveloped coronavirus particles vary widely in size and contour, and are thus refractory to study by traditional structural means such as X-ray crystallography. Electron microscopy (EM) overcomes some problems associated with particle variability
