Learning the enormous number of parameters is a challenging problem in model-based Bayesian reinforcement learning. In order to solve the problem, we propose a model-based factored Bayesian reinforcement learning (F-BRL) approach. F-BRL exploits a factored representation to describe states to reduce the number of parameters. Representing the conditional independence relationships between state ...

Bayesian Reinforcement Learning (BRL) provides an optimal solution to on-line learning while acting, but it is computationally intractable for all but the simplest problems: at each decision time, an agent should weigh all possible courses of action by beliefs about future outcomes constructed over long time horizons. To improve tractability, previous research has focused on sparsely sampling p...

Experiments were designed to study development of bovine embryos in TCM-199 medium conditioned by preculture with buffalo rat liver (BRL) cells. Conditioned media were harvested after BRL cells were cultured until confluency (CON), or for an additional 2 d with the same cells but new medium (CON-N) or the same medium (CON-S). Glucose in TCM-199 was depleted by BRL cells to different concentrati...

Information systems supporting business processes are usually very complex. If we have to ensure that certain business rules are enforced in a business process, it is often easier to design a separate system, called a monitor, that collects the events of the business processes and verifies whether the rules are satisfied or not. This requires a business rule language (BRL) that allows to verify...

The use of Langmuir probes for measuring plasma density is subject to uncertainty because the theories commonly used to interpret the data give widely differing results. This is especially troublesome in partially ionized plasmas used, for instance, in the semiconductor industry, since no existing theory adequately treats the case when there are a few collisions between ions and neutral atoms. ...

Trypanosomatids are increasingly recognized as prevalent in European honey bees (Apis mellifera) and by default are attributed to one recognized species, Crithidia mellificae Langridge and McGhee, 1967. We provide reference genetic and ultrastructural data for type isolates of C. mellificae (ATCC 30254 and 30862) in comparison with two recent isolates from A. mellifera (BRL and SF). Phylogeneti...

Barrelless mice (BRL) homozygous for the BRL mutation that disrupts the gene coding for adenylyl cyclase type I on chromosome 11 lack spatial segregation of layer IV cortical cells and of the thalamocortical axons (TCAs) into barrel domains. Despite these morphological perturbations, a functional topographic map has been demonstrated. We reconstructed individual biocytin-injected TCAs from thal...

objective(s): oxidative stress has been established as a key cause of alcohol-induced hepatotoxicity. licochalcone b, an extract of licorice root, has shown antioxidative properties. this study was to investigate the effects and mechanisms of licochalcone b in ethanol-induced hepatic injury in an in vitro study. materials and methods: an in vitro model of ethanol-induced cytotoxicity in brl cel...

In addition to the indirect and direct costs presented, BRL 917 millions are spent annually with loss of income due to premature death (Table 5). The estimated total amount of potential life years lost was 33,898 years (from the average number of deaths over the years 2012, 2013 and 2014). The maximum age rate was used in a conservative way, to not overestimate the number of days lost due to pr...

The sugar-binding specificities of C-type lectins isolated from marine invertebrates were investigated by frontal affinity chromatography (FAC) using 100 oligosaccharides. The lectins included BRA-2 and BRA-3, multiple lectins from the hemolymph of the acorn barnacle, Megabalanus rosa, and BRL from the acorn barnacle, Balanus rostatus. The diverse sugar-binding specificities of the C-type lecti...
