Occupations have long been central to the study of inequality and mobility. However, occupational categories typical in most U.S. survey data conceal potentially important patterns within occupations. This project uses a novel source that has not previously released for analysis: verbatim text responses provided by respondents General Social Survey from 1972 2018 when asked about their occupati...

This paper presents reinforcement learning with a Long ShortTerm Memory recurrent neural network: RL-LSTM. Model-free RL-LSTM using Advantage( ) learning and directed exploration can solve non-Markovian tasks with long-term dependencies between relevant events. This is demonstrated in a T-maze task, as well as in a di cult variation of the pole balancing task.

An alternative approach in the study of muscle fatigue is to address the question, "What causes task failure during a fatiguing contraction?" This approach is described by considering how variation in the type of load supported and contraction intensity influence both the time to task failure and the centrally mediated adjustments in reflex activity and motor unit behavior.

objectives: this study aimed to identify elderly fallers and non-fallers by balance test under dual tasks conditions. methods & materials: this study was an analyze-comparative study. subjects were from three park of tehran. subjects were 20 older adults with outhistory of falls (aged 75.95±6.28 years) and 21 older adults with a history of 2 or more falls in the previous one year (aged 72.50±7....

Conventional application of hidden Markov models to the task of recognizing human gesture may su er from multiple sources of systematic variation in the sensor outputs. We present two frameworks based on hidden Markov models which are designed to model and recognize gestures that vary in systematic ways. In the rst, the systematic variation is assumed to be communicative in nature, and the inpu...

The aim of the present study was to observe the changes in hand flexibility of patients with Parkinson's disease (PD) and the effect of dual-task interference. Patients with PD were distributed into two subgroups: the leucine-rich repeat kinase 2 (LRRK2) mutation PD (LRRK2+) and the LRRK2 mutation-free (LRRK2-) PD groups. The healthy controls were distributed into two subgroups: the LRRK2+ cont...

background: decay products of radon and thoron present in indoor environment are the most important sources of radiation from natural sources which affect human beings, since general public spend at lest 80% of their time in indoor. materials and methods: air samples were collected for measuring the concentration of radon and thoron daughter products from various indoor environments during four...
