The fluorescence and scattering properties of Prochlorococcus and Synechococcus at Station ALOHA as measured by flow cytometry (termed the FCM phenotype) vary with depth and over a variety of time scales.The variation in FCM phenotypes may reflect population selection or physiological acclimation to local conditions.Observations before, during, and
Preparation and properties of open-cell zinc foams as human bone substitute material
Foamed zinc was prepared by infiltration casting process.The Heels mechanical properties and corrosion resistance of the samples were studied, and the feasibility of the foamed zinc as a bone implant material was discussed.All the compression stress-strain curves of open-cell zinc foams with various cell size (1-4 mm) and porosity (55%-67%) show th
Automated Detection, Localization, and Severity Assessment of Proximal Dental Caries from Bitewing Radiographs Using Deep Learning
Background/Objectives: Dental caries is a widespread chronic infection, affecting a large segment of the population.Proximal caries, in particular, present a distinct obstacle for early identification owing to their position, which hinders clinical inspection.Radiographic assessments, particularly bitewing images (BRs), are frequently utilized to d
Grease film evolution in rolling elastohydrodynamic lubrication contacts
Abstract Although most rolling element bearings are grease lubricated, the underlying mechanisms of grease lubrication has not been fully explored.This study investigates grease BAKING film evolution with glass disc revolutions in rolling elastohydrodynamic lubrication (EHL) contacts.The evolution patterns of the grease films were highly related to
