An Time Go Backward?

چکیده
Time has been described by many metaphors, but none is older or more persistent than the image of time as a river. You cannot step twice in the same river, said Heraclitus, the Greek philosopher who stressed the temporal impermanence of all things, because new waters forever flow around you. You cannot even step into it once, added his pupil Cratylus, because while you step both you and the river are changing into something different. As Ogden Nash put it in his poem "Time Marches On,"

Effect of Backward Walking on Attention: Possible Application on ADHD
The human requires attentive effort as assessed in dual-task experiments. Consistently, an attentive task can modify the walking pattern and a attention deficit and hyperactivity disorder (ADHD) is accompanied by gait modifications. Here we investigated the relationships between backward walking and attentive performances in ADHD children (n=13) and healthy age-, height and weight matched contr...
متن کاملOptimal Backward and Backup Policies in Reliability Theory
Abstract We are sometimes faced with the problem of searching for the actual failure time of a unit when it has failed until time t0. This is called a backward time problem of how much time we go back to search for the failure time from time t0, and is solved by using the reversed failure rate. This paper proposes an extended model of multiple backward trials in which we find the actual failure...
متن کاملShifting Evaluation Windows: Predictable Forward Primes with Long SOAs Eliminate the Impact of Backward Primes
Recent work suggests that people evaluate target stimuli within short and flexible time periods called evaluation windows. Stimuli that briefly precede a target (forward primes) or briefly succeed a target (backward primes) are often included in the target's evaluation. In this article, the authors propose that predictable forward primes act as "go" signals that prepare target processing, such ...
متن کاملThe role of response selection for inhibition of task sets in task shifting.
Response selection in task shifting was explored using a go/no-go methodology. The no-go signal occurred unpredictably with stimulus onset so that all trials required task preparation but only go trials required response selection. Experiment 1 showed that shift costs were absent after no-go trials, indicating that response processes are crucial for shift costs. In Experiment 2, backward inhibi...
متن کاملFe3O4 Magnetic Nanoparticles/ Graphene Oxide Nanosheets/Carbon Cloth as an Electrochemical Sensing Platform
In this work, for eliminating the (RR1346), considered to be a waste in wastewater from dye industries electrochemical advanced oxidation process has been used. Graphene oxide coated carbon cloth (GO/CC) and Fe3O4 /GO coated carbon cloth (Fe3O4/GO/CC) electrodes has been fabricated by synthesized GO and Fe3O4 nanoparticles. Characteristic properties such as surface morphology as the main reason...
متن کاملEffects of changing stance conditions on anticipatory postural adjustment and reaction time to voluntary arm movement in humans.
1. The effect on reaction time (RT) and anticipatory postural adjustment (APA) of unexpectedly changing stance conditions was studied using a push or pull arm movement task. The aim was to evaluate the modifiability of RT and APA by an external perturbation associated with an automatic compensatory reaction. 2. Subjects standing on a moveable platform were asked to push or pull a rigid handle a...
