Optimization of real-world black-box functions defined over purely categorical variables is an active area research. In particular, optimization and design biological sequences with specific functional or structural properties have a profound impact in medicine, materials science, biotechnology. Standalone search algorithms, such as simulated annealing (SA) Monte Carlo tree (MCTS), are typicall...

In the present work, cupric oxide (CuO) films were obtained through thermal annealing of the copper (Cu) films deposited on quartz substrates by DC magnetron sputtering method. The annealing was performed in air atmosphere for different times ranging from 60-240 min at temperature of 400 ºC. The influence of annealing times on structural and morphological properties of the films was investi...

The cycling parameters for BOX A1R PCR were modified and the primer-specific annealing temperature was optimized. Using Trout Lake Escherichia coli isolates, four different template preparation methods were compared. The cell washing, heat lysis, and DNA isolation methods all gave clear and bright band patterns with good reproducibility. The cell washing template preparation method for direct u...

This paper describes a simple and accurate model for boron diffusion in SiGe that was successfully implemented in TAURUS (PMEI). The comparison of the Si,.,Ge, samples to the Si samples after rapid thermal and furnace annealing revealed a retarded B diffusion inside the strained Sil.,Ge, layers. The influence of the Ge content on the dopant diffusion was also measured and simulated, demonstrati...

In this paper, a new heuristic for approximating the maximum clique problem is proposed, based on a detailed analysis of a class of continuous optimization models which yield a complete solution to this NP-hard combinatorial problem. The idea is to alter a regularization parameter iteratively in such a way that an iterative procedure with the updated parameter value would avoid unwanted, ine ci...

the increasing demand for rice in ghana has been a major concern to the government and other stakeholders. recent concerns by the coalition for african rice development (card) to double rice production within ten years in sub-saharan countries have triggered the to implement strategies to boost rice production in the government. to fulfill this requirement, there is a need to monitor and foreca...

magnetic nanoparticles can bind to different drug delivery systems and can be used for drug targeting to a specific organ by using an external magnetic field as well as used in hyperthermia by heating in alternating magnetic fields. the characteristics of iron oxide nanoparticles are significantly affected by particle size, shape and zeta potential, among which the particle size plays the most ...

background: determining the temporal variation and forecasting the incidence of smear positive tuberculosis (tb) can play an important role in promoting the tb control program. its results may be used as a decision-supportive tool for planning and allocating resources. the present study forecasts the incidence of smear positive tb in iran. methods: this a longitudinal study using monthly tuberc...

mutual information (mi) is a widely used similarity metric for multimodality image registration. however, it involves an extremely high computational time especially when it is applied to volume images. moreover, its robustness is affected by existence of local maxima. the multi-resolution pyramid approaches have been proposed to speed up the registration process and increase the accuracy of th...

cofe/cu multilayer nanowires were electrodeposited into anodic aluminum oxide templates prepared by a two-step mild anodization method, using the single-bath technique. nanowires with 30 nm diameter and the definite lengths were obtained. the effect of cofe layers thickness and annealing on the magnetic behavior of the multilayer nanowires was investigated. the layers thickness was controlled t...
