in this paper we have down three theoretical study by using monte carlo simulation and mm+,amber and opls force field. the calculations were carried out using hyper chem professional,release 7.01 package of program. first we have studied the interaction of h2 molecule and he atomwith single-walled carbon nanotube at different temperature. for doing this study we placed h2 andhe in the center an...

We provide a method for estimating the generalization error of a bag using out-of-bag estimates. In bagging, each predictor (single hypothesis) is learned from a bootstrap sample of the training examples; the output of a bag (a set of predictors) on an example is determined by voting. The outof-bag estimate is based on recording the votes of each predictor on those training examples omitted fro...

HAP46/BAG-1M and its isoforms affect the protein-folding activities of mammalian HSP70 chaperones. They interact with the ATP-binding domain of HSP70 or HSC70, leaving the substrate-binding site available for further interactions. Trimeric complexes can therefore form with, for example, transcription factors. Moreover, HAP46/BAG-1M and the larger isoform HAP50/BAG-1L bind to DNA non-specificall...

Phthalocyanine and porphyrin were among the first organic compounds investigated by means of electronic spectroscopy in superfluid helium nanodroplets. Superfluid helium nanodroplets serve as a very gentle host system for preparing cold and isolated molecules. The uniqueness of helium nanodroplets is with respect to the superfluid phase which warrants the vanishing viscosity and, thus, minimal ...

A laboratory experiment was conducted with bean seeds kept in three different containers viz. tin pot, poly bag and jute bag and stored at room temperature and RH for three months in the Laboratory of Agronomy Department, Sher-eBangla Agricultural University to study their storage behavior, germination percentage and quality. The seed of jute bag came to the contact with air and their moisture ...

Dissociated Aplysia neurons will regenerate neurites and form functional connections in primary cell cultures. The specificity of intercellular connectivity in these cultures was investigated by coculturing neurosecretory bag cells with neurons dissociated from the buccal ganglion. It was found that bag-bag and buccal-buccal electrotonic synapses form with high frequency, consistent with previo...

The 70 kDa heat shock family of molecular chaperones is essential to a variety of cellular processes, yet it is unclear how these proteins are regulated in vivo. We present evidence that the protein BAG-1 is a potential modulator of the molecular chaperones, Hsp70 and Hsc70. BAG-1 binds to the ATPase domain of Hsp70 and Hsc70, without requirement for their carboxy-terminal peptide-binding domai...

Aims. We examine a recently–proposed evolutionary scenario that could explain the existence of the low–mass, helium– enriched PG1159 stars. We focus in particular on the study of the pulsational stability properties of the evolutionary models predicted by such scenario. Methods. We assess the overstability of pulsation g−modes of stellar models as evolution proceeds along the PG1159 domain. Ste...

In multi-instance (MI) learning, each object (bag) consists of multiple feature vectors (instances), and is most commonly regarded as a set of points in a multidimensional space. A different viewpoint is that the instances are realisations of random vectors with corresponding probability distribution, and that a bag is the distribution, not the realisations. In MI classification, each bag in th...
