Deep reinforcement learning (DRL) has reached an unprecedent level on complex tasks like game solving (Go [], StarCraft II []), and autonomous driving. However, applications to real financial assets are still largely unexplored it remains open question whether DRL can reach super human level. In this demo, we showcase state-of-the-art methods for selecting portfolios according environment, with...

Diffusion weighted (DW) MRI facilitates non-invasive quantification of tissue microstructure and, in combination with appropriate signal processing, three-dimensional estimates of fibrous orientation. In recent years, attention has shifted from the diffusion tensor model, which assumes a unimodal Gaussian diffusion displacement profile to recover fibre orientation (with various well-documented ...

The goal of this study was to compare the ability of morphology and molecular-based surveys to estimate species richness for two species-rich diatom genera, Chaetoceros Ehrenb. and Thalassiosira Cleve, in the Bay of Fundy. Phytoplankton tows were collected from two sites at intervals over two years and subsampled for morphology-based surveys (2010, 2011), a culture-based DNA reference library (...

Objective: The aim of this study was two fold. To determine the diagnostic reference level (D.R.L.) dose of radiation during dynamic hip screw (D.H.S.) fixation and, to audit the orthopaedic department against this standard. Methods and Materials: A retrospective analysis of 112 consecutive patients between 31st December 2002 and the 6th July 2003, at Darenth Valley Hospital, Dartford, under go...

The serotonergic (5-HTergic) system arising from the dorsal raphe nucleus (DRN) is implicated in various physiological and behavioral processes, including stress responses. The DRN is comprised of several subnuclei, serving specific functions with distinct afferent and efferent connections. Furthermore, subsets of 5-HTergic neurons are known to coexpress other transmitters, including GABA, glut...

Behavioral impairment as a consequence of PCB exposure beginning in utero has been reported in both humans and animals. The present study assessed the behavioral consequences of postnatal exposure to PCBs. Male monkeys (Macaca fascicularis) were dosed from birth to 20 weeks of age with 7.5 microg/kg/ day of a PCB mixture representative of the PCBs typically found in human breast milk (eight mon...

Pregnant Sprague-Dawley rats received a single oral dose of 0, 20, 60, or 180 ng/kg 2,3,7,8-tetrachlorodibenzo-p-dioxin on day 8 of gestation. Each litter contributed a single male-female pair trained to press a lever to obtain food pellets under two operant behavior procedures. Initially, each lever press was reinforced. The fixed-ratio (FR) requirement was then increased every four sessions f...
