Reinforcement learning (RL) methods have become popular in recent years because of their ability to solve complex tasks with minimal feedback. Both genetic algorithms (GAs) and temporal difference (TD) methods have proven effective at solving difficult RL problems, but few rigorous comparisons have been conducted. Thus, no general guidelines describing the methods’ relative strengths and weakne...

For small scattering lengths, cold bosonic atoms form a condensate the density profile of which is smooth. With increasing scattering length, the density gradually acquires more and more oscillations. Finally, the number of oscillations equals the number of bosons and the system becomes fermionized. On this pathway from condensation to fermionization intriguing phenomena occur, depending on the...

BACKGROUND Mobile health (mHealth) services cannot easily adapt to users' unique needs. PURPOSE We used simulations of text messaging (SMS) for improving medication adherence to demonstrate benefits of interventions using reinforcement learning (RL). METHODS We used Monte Carlo simulations to estimate the relative impact of an intervention using RL to adapt SMS adherence support messages in...

thymus is a medicinal plant which contains one of the world's top ten essential oils, exhibiting antibacterial, antioxidative, food preservative and mammalian age-delaying properties. this work was aimed at identifying between-species variations requiring for selecting appropriate parents for hybridization. six iranian endemic thymus accessions belonging to thymus daënensis, t. eriocalyx and t....

In this paper a relative localization (RL) system for quadcopters based on ultra-wideband (UWB) ranging measurements is proposed. To achieve the relative localization, UWB modules are installed on the quadcopters to actively measure distances and exchange data package to a hovering quadcopter which is equipped with an identical UWB module. Since instantaneous distanceonly measurements cannot pr...

conclusions ia fluid resuscitation is superior to iv resuscitation in hemorrhagic shock induced cardiac arrest. results while iv rl infusion failed to restore chest motion in mice (n = 5), ia rl infusion restored chest motion in all mice examined (n = 6) (p = 0.0067). in three mice, iv rl infusion after cardiac arrest showed no effect on cc. after failure of venous infusion, ia rl infusion was ...

A pericentric inversion of chromosome 18 is described in the mother of a patient with clinical diagnosis of 18q--syndrome. The propositus' chromosome complement includes the recombinant 18 with deficiency of the distal one-third of the long arm and duplication of the terminal segment of the short arm. The propositus' sister carrier the recombinant 18 with a duplication of the distal one-third o...
