The 5-HT7 receptor binding affinities of the oxindole derivatives have been quantitatively analyzed in terms of Dragon descriptors. The derived QSAR models have provided rationales to explain the binding affinity of titled compounds. In order to improve the 5-HT7 receptor binding affinity of a compound higher value of molecular topology and symmetry accounting parameter path/walk 2Randic shape ...

The decree of the Central Committee All-Union Communist Party Bolsheviks on primary and secondary schools is a historical document path building Soviet school.

This paper describes the path selection function in Networking BroadBand Services (NBBS), which is IBMs architecture for high-speed, multimedia networks. The distinguishing feature of a multimedia network is its ability to integrate different applications with different traffic characteristics and service requirements in the network, such as voice, video, and data. In order to meet their servic...

this is a summary of an extended research on the sociological study of theft in iran. the main purpose of the study has been to identify and analyze the social correlates of theft rate, which, admittedly, has been increasing in iran in recent years. the research question was: “what are the causes of theft rate variations in various provinces of iran?” the research unit of the study is the provi...

A well known algorithm in the field of active noise control is the filtered-x algorithm. As known in literature, the convergence properties of an adaptive algorithm can be improved by decorrelating its input signal. In this paper, the decorrelation needed for the filtered-x algorithm is discussed with the help of block frequency domain adaptive filters. It is shown that decorrelation of not onl...

A quantitative understanding of nucleic acid hybridization is essential to many aspects of biotechnology, such as DNA microarrays, as well as to the structure and folding kinetics of RNA. However, predictions of nucleic acid secondary structures have long been impeded by the presence of helices interior to loops, so-called pseudoknots, which impose complex three-dimensional conformational const...

In this paper, we propose a shadow play animation system that utilizes motion planning algorithms to generate Chinese shadow play animation automatically according to user’s highlevel inputs. The motion of a character in a shadow play show usually consists of intended primary motion and reactive secondary motion. We propose to use the RRT-Connect algorithm to generate primary motions and design...

Reactions occurring at a carbon atom through the Walden inversion mechanism are one of the most important and useful classes of reactions in chemistry. Here we report an accurate theoretical study of the simplest reaction of that type: the H+CH4 substitution reaction and its isotope analogues. It is found that the reaction threshold versus collision energy is considerably higher than the barrie...

In the beam pipe of the positron Main Damping Ring (MDR) of the Next Linear Collider (NLC), ionization of residual gases and secondary electron emission give rise to an electron cloud which can cause the loss of the circulating beam. One path to avoid the electron cloud is to ensure that the vacuum wall has low secondary emission yield and, therefore, we need to know the secondary emission yiel...
