A common assumption in visual attention is based on the rationale of ＂limited capacity of information processing＂. From this view point there is little consideration of how different information ch.nnels or modules are cooperating because cells in processing stages are forced to compete for the limited resource. To examine the mech.nism behind the cooperative behavior of information ch.nnels, a computational model of selective attention is implemented based on two hypotheses. Unlike the traditional view of visual attention, the cooperative behavior is assumed to be a dynamic integration process between the bottom-up and top-down information. Furthermore, top-down information is assumed to provide a contextual cue during selection process and to guide the attentional allocation among many bottom-up candidates. The result from a series of simulation with still and video images showed some interesting properties that could not be explained by the competitive aspect of selective attention alone.

The first Zagreb index M1 （G） is equal to the sum of squares of the degrees of the vertices, and the second Zagreb index M2 （G） is equal to the sum of the products of the degrees of pairs of adjacent vertices of the underlying molecular graph G. In this paper, we obtain lower and upper bounds on the first Zagreb index MI（G） of G in terms of the number of vertices （n）, number of edges （m）, maximum vertex degree （△）, and minimum vertex degree （δ）. Using this result, we find lower and upper bounds on M2（G）. Also, we present lower and upper bounds on M2（G）＋ M2（G） in terms of n, m, △, and δ, where denotes the complement of G. Moreover, we determine the bounds on first Zagreb coindex MI（G） and second Zagreb coindex M2（G）. Finally, we give a relation between the first Zagreb index and the second Zagreb index of graph G.

A wide variety of processes are being pursued by research.rs for cost effective extraction of titanium metal. Electroch.mical processes are promising due to simplicity and being less capital intensive. Some of the promising electroch.mical processes of titanium extraction were reviewed and the results of laboratory scale experiments on electroch.mical reduction of TiO2 granules were brought out. Some of the kinetic parameters of the reduction process were discussed while presenting the quality improvements ach.eved in the experimentation.

We present recent investigations on the vector and axial-vector transitions of the baryon antidecuplet within the framework of the self-consistent SU（3） ch.ral quark-soliton model, taking into account the 1/No rotational and linear mscorrections. The main contribution to the electric-like transition form factor comes from the wave-function corrections. This is a consequence of the generalized Ademollo-Gatto theorem. It is also found that in general the leading-order contributions are almost canceled by the rotational 1/No corrections. The results are summarized as follows： the vector and tensor K＇NO coupling constants, gK＊N= 0.74--0.87 and fk＊N =0.53--1.16, respectively, and F→KN = 0.71 MeV, based on the result of the KN coupling constant gKne =0.83. We also show the differential cross sections and beam asymmetries, based on the present results. We also discuss the connection of present results with the original work by Diakonov, Petrov, and Polyakov.

Diamond films were prepared by electron-assisted ch.mical vapor deposition (EACVD) system, and the thermal diffusivities of the films with or without substrate were studied by use of photothermal deflection (PTD) tech.ique. The results show that less non-diamond component and larger crystalline size result in higher thermal conductivity of CVD diamond film. The influence of substrate on the measurement of thermal conductivity of the film was investigated, and a simple two-layer heat conduction model is given to account for the influence and used to draw the thermal conductivity of the film from the effective thermal diffusivity of film/substrate system.
