In order to improve the service life of the needle roller bearing used in a precision cycloid reducer, and to reveal the skew and collision phenomenon of the needle roller bearing, based on the force analysis of the transmission mechanism of the cycloid reducer and considering the friction between the cycloid wheel, needle roller, cage, and crank s
This paper estimated the effects of tort law and insurer investment returns on physician malpractice insurance premiums.Data were collected on tort law from 1991 through 2004, and multivariate regression models, including fixed effects for state and year, were used to estimate the effect of changes in tort law on medical malpractice premiums.The pr
We consider the design of near-capacity-achieving error-correcting codes for a discrete multitone (copyright) system in the presence of both additive white Gaussian noise and impulse noise.Impulse noise is one of the main channel impairments for digital subscriber lines (DSL).One way to combat impulse noise is to detect the presence of the impulses
Background: In sickle cell disease (SCD), reduced bioavailability of endothelial NO and cGMP results in reduced expression of phosphodiesterase type 5 (PDE5), thus impairing the penile erection control mechanism and resulting in prolonged penile erection (priapism).In SCD, reduced NO bioavailability is associated with excess plasma hemoglobin due t
Abstract To tackle challenges such as convergence difficulties and suboptimal performance in the application of reinforcement learning veuve ambal rose to intelligent decision-making for joint operations, this study introduces an enhanced decision-making approach for joint operations utilizing an improved Proximal Policy Optimization (PPO) algorith
