Computational evaluation of different arrangements for the circadian clock in Arabidopsis thaliana.
University of Stavanger Norway, 2019Co-Authors: Khan, Shanawar AliAbstract:The circadian clock is an endogenous timekeeper that enables individuals to predict and adjust to their environment's regular differences between light and dark and high and low temperatures. This biological timing mechanism enables the organism coordinate evolutionary and metabolic occurrences to the best time of the day. Such a system is of significant value to plants as they cannot alter their place when the climate becomes detrimental as opposed to animals. The plant clock is a sophisticated system of interwoven feedback loops. Mathematical modeling methods have been used over the past few decades to comprehend the clock's internal functioning in the Arabidopsis thaliana model plant. These attempts have generated a range of increasingly complex designs. Here, a review of the research is presented which is done in order to find out the molecular machinery responsible for circadian rhythms. Along with this, a simple model and alterations in this model are conducted to check out the impact of such changes on phases as well as period of rhythms. An effort is also done to Show Comparison of model in relation to the findings presented in previous research. We are proposing an applicant model centered on LSODE optimization sub-routine calculation

anisotropic spectral spatial total variation model for multispectral remote sensing image destriping
IEEE Transactions on Image Processing, 2015Co-Authors: Yi Chang, Luxin Yan, Houzhang Fang, Chunan LuoAbstract:Multispectral remote sensing images often suffer from the common problem of stripe noise, which greatly degrades the imaging quality and limits the precision of the subsequent processing. The conventional destriping approaches usually remove stripe noise band by band, and Show their limitations on different types of stripe noise. In this paper, we tentatively categorize the stripes in remote sensing images in a more comprehensive manner. We propose to treat the multispectral images as a spectral-spatial volume and pose an anisotropic spectral-spatial total variation regularization to enhance the smoothness of solution along both the spectral and spatial dimension. As a result, a more comprehensive stripes and random noise are perfectly removed, while the edges and detail information are well preserved. In addition, the split Bregman iteration method is employed to solve the resulting minimization problem, which highly reduces the computational load. We extensively validate our method under various stripe categories and Show Comparison with other approaches with respect to result quality, running time, and quantitative assessments.

antifungal and antibacterial resistance profiles between cambodia and kenyan children with human immunodeficiency virus infections receiving trimethoprim sulfamethoxazole prophylaxis
Pediatric Infectious Disease Journal, 2005Co-Authors: Andrea Doczeova, Alžbeta Kolenova, P Beno, Anna Liskova, Alexandra Stanova, V Krcmery, Ritu Banerjee, Adam L Hersh, Thomas B Newman, Susanna EspositoAbstract:There is a fear that antibacterial prophylaxis with trimethoprim-sulfamethoxazole (TMP-SMX) in children with acquired immunodeficiency syndrome (AIDS)1 might lead to increase of antimicrobial resistance in bacteria. We compared culture results and resistance pro- files in children receiving TMP-SMX prophylaxis 3 times weekly orally in Phnom Penh Cambodia and in Nairobi Kenya after 12–18 months of highly active antiretroviral therapy (HAART) therapy. Thirty-three children from Phnom Penh (group A) and 42 patients from Nairobi (group B) were compared. CD4 count varied from 10 to 220 at admission. Oropharyngeal swab cultures were transported to the reference laboratory of antimicrobial resistance of the Slovak Ministry of Health. Tables 1 and 2 Show Comparison of culture results and resistance patterns in human immunodeficiency virus-positive children in Phnom Penh and Nairobi at the initiation of HAART and after 12–18 months of therapy.
