A new species of early actinopterygian Outdoors fishes, Moythomasia lebedevi sp.nov., is described based on numerous isolated scales occurring in Middle Devonian (Givetian, Polotskian Regional Stage) marine deposits (Goryn, Stolin and Moroch Beds) of Belarus.These scales characterize different ontogenetic stages (adult and subadult) of the fish.Few
To survive, animals must learn to control their movements with millisecond-level precision, and adjust the kinematics if conditions, or task requirements, change.Here, we examine adaptive timing of motor output in mice, using a simple eyelid conditioning task.Mice were trained to blink in response to a light stimulus that was always followed by a c
Aim: This study assessed the risk factors of undergraduate students to develop musculoskeletal disorders (MSD) in the upper limbs, regarding gender, type of dental clinical procedure, mouth region treated, and the four-handed dentistry practice.Methods: Dental students enrolled in the 8th semester in the Araraquara School of Dentistry, UNESP, Brazi
Fighting has been part of the fabric of the NHL for nearly a century.Recent sharp declines in the frequency of fighting and increased understanding of the long-term consequences of traumatic brain injuries have led many to question whether fighting still has a place in the modern NHL.League commissioner Gary Bettman as recently as 2019 testified be
An analytical model is presented that allows predicting the progress and the final depth obtained by laser micromachining of grooves in Hayward SP0704 Valve Parts metals with ultrashort laser pulses.The model assumes that micromachined grooves feature a V-shaped geometry and that the fluence absorbed along the walls is distributed with a linear inc
