In this paper we describe how an actor critic rein forcement learning agent in a non Markovian domain nds an optimal sequence of actions in a totally model free fashion that is the agent neither learns transitional probabilities and associated rewards nor by how much the state space should be augmented so that the Markov prop erty holds In particular we employ an Elman type re current neural ne...

Time is at th e heart of many pat tern recognition t asks, e.g., speech recognit ion . However, connectionis t learning algorithms to date are not well suited for dealing with tim e-varying input patterns.

Transcription of the P1 promoter of the Escherichia coli proP gene, which encodes a transporter of osmoprotectants, is strongly induced by a shift to hyperosmotic media. Unlike most other osmotically regulated promoters, the induction occurs for a brief period of time, corresponding to the replacement of intracellular K(+) glutamate with osmoprotecting compounds. This burst of proP transcriptio...

Taste is one of the main factors determining food choices. Differences in PROP bitter taste perception have been implicated in individual differences in food preferences and selection. The present study examined associations between, PROP phenotypes, self-reported food liking and TAS2R38 polymorphisms, the major gene implicated in PROP bitterness, in six different populations of the Caucasus an...

Previous reports that the sensitivity to the bitter tasting substance 6-n-propylthiouracil (PROP) is related to the sensitivity to other tastes, to chemical irritants, and to fats and oils have led to adoption of PROP as a measure of general oral sensitivity and as a predictor of dietary habits that could impact health. The results, however, have not been consistent. It was recently discovered ...

Sensitivity to the bitter taste of 6-n-propylthiouracil (PROP) is an inherited trait. Although some people find PROP to be extremely bitter, others cannot distinguish PROP solutions from plain water. In a series of studies, greater PROP sensitivity was linked with lower acceptability of other bitter compounds and with lower reported liking for some bitter foods. Women, identified as "super-tast...

Seven different strains of Trichoderma are isolated from wilt infected leguminous crops of a Madhya Pradesh state and tested for their antagonistic activity against Fusarium (soil borne pathogen) which is expressed as a zone of inhibition in the culture plates. The seven strains are identified as Trichoderma viride, T. harzianum, T. asperellum, T. koningii, T. atroviride, T. longibrachiatum, an...

We show Koszulness of the prop governing involutive Lie bialgebras and also of the props governing non-unital and unital-counital Frobenius algebras, solving a long-standing problem. This gives us minimal models for their deformation complexes, and for deformation complexes of their algebras which are discussed in detail. Using an operad of graph complexes we prove, with the help of an earlier ...

In the title compound, C(42)H(46)N(2)O(4), both crystallographically independent mol-ecules display a 1,3-alternate conformation. Their crystal packing is stabilized by non-classical C-H⋯N hydrogen bonds. The dihedral angles between the planes of the aromatic rings and the mean plane through the methyl-ene C atoms bridging the aromatic rings are 78.10 (13), 80.74 (14), 81.89 (12) and 79.05 (14)...

We introduce the notion of a multi-vector sentence representation based on a “one vector per proposition” philosophy, which we term skip-prop vectors. By representing each predicate-argument structure in a complex sentence as an individual vector, skip-prop is (1) a response to empirical evidence that single-vector sentence representations degrade with sentence length, and (2) a representation ...
