Profiling of a Pitcher’s Performance with a Smart Baseball: A Case Report
Proceedings, 2020 A pitcher’s action, when delivering a fastball, was analyzed from the data provided by a smart baseball. The spin rate at the release of the ball was merely 15.7 rps, however, the peak torque was excessively high, namely 0.396 Nm.

Effect of spin labelling on the aggregation kinetics of yeast prion protein Ure2 [PDF]
Royal Society Open Science, 2021 Amyloid formation is involved in a wide range of neurodegenerative diseases including Alzheimer's and prion diseases. Structural understanding of the amyloid is critical to delineate the mechanism of aggregation and its pathological spreading.

Measurement of Flight Dynamics of a Frisbee Using a Triaxial MEMS Gyroscope
Proceedings, 2020 A Frisbee with a mass of 0.21 kg, diameter of 0.27 m and moment of inertia (MOI) of 0.002 kg·m2 was instrumented with a triaxial gyroscope. The Frisbee was thrown at low angular velocities as the measurement limit of a single gyroscope was at 6.065 rps ...

Bowling Performance Assessed with a Smart Cricket Ball: A Novel Way of Profiling Bowlers
Proceedings, 2020 Profiling of spin bowlers is currently based on the assessment of translational velocity and spin rate (angular velocity). If two spin bowlers impart the same spin rate on the ball, but bowler A generates more spin rate than bowler B, then bowler A has a

Spin relaxation rate for heavy quarks in weakly coupled QCD plasma
Journal of High Energy Physics, 2022 We compute the relaxation rate of the spin density of heavy quarks in a perturbative QCD plasma to leading-log order in the coupling constant g. The spin relaxation rate Γ s in spin hydrodynamics is shown to be Γ s ~ g 4 log(1/g)T(T/M)2 in the heavy ...
