Back-Prop and No-Prop, two training algorithms for multi-layer neural networks, are compared in design and performance. With Back-Prop, all layers of the network receive least squares training. With No-Prop, only the output layer receives least squares training, whereas the hidden layer weights are chosen randomly and then fixed. No-Prop is much simpler than Back-Prop. No-Prop can deliver equal...

BACKGROUND Phenylthiocarbamide (PTC) and 6-n-propylthiouracil (PROP), chemically related compounds, are probes for genetic variation in bitter taste, although PROP is safer with less sulfurous odor. Threshold for PROP distinguishes nontasters (increased threshold) from tasters (lower threshold); perceived intensity subdivides tasters into medium tasters (PROP is bitter) and supertasters (PROP i...

Two experiments were conducted to compare young and older adults' processing of complex sentences involving quantifier scope ambiguities. Young adults were hypothesized to use a mix of syntactic processing strategies to interpret sentences such as Every actor used a prop or An actor used every prop. Older adults, particularly those with limited working memories, were hypothesized to rely on a s...

Thiourea tasting can be predictive of individual differences in bitter taste responses, general food preferences and eating behavior, and could be correlated with saliva chemical composition. We investigated the possible relationship between PROP bitter taste responsiveness and the salivary proteome in subjects genotyped for TAS2R38 and gustin gene polymorphisms. Taste perception intensity evok...

Iterative-improvement 2-way min-cut partitioning is an important phase in most circuit placement tools, and finds use in many other CAD applications. Most iterative improvement techniques for circuit netlists like the FiducciaMattheyses (FM) method compute the gains of nodes using local netlist information that is only concerned with the immediate improvement in the cutset. This can lead to mis...

Genetically mediated taste responsiveness to 6-n-propylthiouracil (PROP) has been linked to reduced acceptance of some bitter foods. In this community-based study male (n = 364) and female (n = 378) adults enrolled in a self-help dietary intervention trial were screened for PROP taster status. Respondents, aged 18--70 years, were mailed filter papers impregnated with PROP or with aspartame solu...

We consider graph complexes with a flow and compute their cohomology. More specifically, we prove that for a PROP generated by a Koszul dioperad, the corresponding graph complex gives a minimal model of the PROP. We also give another proof of the existence of a minimal model of the bialgebra PROP from [14]. These results are based on the useful notion of a 1 2 PROP introduced by Kontsevich in [9].

We prove that any category of props in a symmetric monoidal model category inherits a model structure. We devote an appendix, about half the size of the paper, to the proof of the model category axioms in a general setting. We need the general argument to address the case of props in topological spaces and dg-modules over an arbitrary ring, but we give a less technical proof which applies to th...

Prophet of Pit-1 (Prop-1), which is a paired-like homeodomain transcription factor, is capable of binding to sites in an early enhancer of the Pit-1 gene and regulating its expression. According to a previous report, Prop-1 messenger RNA (mRNA) is expressed in the developing pituitary gland before Pit-1 mRNA expression and maximum expression are observed at e 12.0. After e 14.5, Prop-1 mRNA exp...
