We have used fluorescent latex beads to label membrane receptors on cultured NRK cells. Movement of individual beads during cell division was recorded with digital imaging techniques. Surface-bound beads showed no organized movement during metaphase but started to migrate toward the equator ,,ol min after anaphase onset, when chromosomes moved out of the equatorial region to create the interzon...

Optimal design of large-scale structures is a rather difficult task and the computational efficiency of the currently available methods needs to be improved. In view of this, the paper presents a modified Charged System Search (CSS) algorithm. The new methodology is based on the combination of CSS and Particle Swarm Optimizer. In addition, in order to improve optimization search, the sequence o...

the need for simulation of human foot mechanism has made researchers and engineers move towards different patterns to describe this movement. in this regard, optimal solutions such as energy consumption, accuracy, etc. are of utmost importance. in this paper, efforts have been made to present a new solution by designing a fully two-dimensional six-bar mechanism with one degree of freedom so tha...

it is indirectly involved by transporting an anchor that ASH1 mRNA localizes to the bud tip in Saccharomyces subsequently binds the RNA to the bud cortex (Long et cerevisiae to establish asymmetry of HO expression, al., 1997). Distinguishing between these mechanisms important for mating type switching. To visualize real requires a method to characterize RNA movement within time localization of ...

Particle tracking methods are a versatile computational technique central to the simulation of a wide range of scientiic applications. In this paper we present a new parallel approach for the dynamic partitioning of particle-mesh computational systems. The approach uses a framework, the \in-element" particle tracking method, based on the assumption that particle trajectories are computed by pro...

In order to optimize the spectrum resource allocation in the orthogonal frequency division multiplexing system and minimize the transmitted power, this paper proposed a modified basic particle swarm optimization algorithm to allocate the subcarriers and bits of the orthogonal frequency division multiplexing system. The algorithm uses the average individual extreme value instead of individual ex...

In this paper, a Three Dimensional Pedestrian Movement Model (3D-MM) capable of probabilistically representing pedestrian movement in challenging indoor and outdoor localization environments is developed, implemented and evaluated. In the scope of this paper, the model is used to generate a ‘movement’ or a transition for dynamic positioning systems that are based on sequential Bayesian filterin...

Quantifying the fine-scale movement patterns and habitat use of active fishes has historically been challenging due to their scope of movement or the labor intensive nature of actively tracking potentially wide-ranging species. This project focuses on improving the localization accuracy and temporal resolution of an acoustically tagged fish by filtering the position measurements received from a...
