The area of smart power grids needs to constantly improve its efficiency and resilience, provide high quality electrical in a resilient grid, while managing faults avoiding failures. Achieving this requires component reliability, adequate maintenance, studied failure occurrence. Correct system operation involves those activities novel methodologies detect, classify, isolate failures model simul...
methoxymethylation of a variety of alcohols was performed using formaldehyde dimethyl acetal in the presence of 1,3-dichloro-5,5-dimethyl hydantoin [dcdmh] and poly n,n′-dibromo-n-ethyl naphthyl-2,7-disulfonamide [pbns] as catalysts at room temperature and under solvent-free conditions. our experiments show that primary and secondary alcohols can be smoothly converted into the corresponding mom...

Despite advances in the therapeutic use of recombinant granulocyte colony-stimulating factor (G-CSF) to promote granulopoiesis of human hematopoietic stem cells (HSCs), neutropenia remains one of the most serious complications of cancer chemotherapy. We discovered that retinoid agonist Am80 (tamibarotene) is more potent than G-CSF in coordinating neutrophil differentiation and immunity developm...
1) پلیمر عامل دارشده پلی (n ،n - دی برمو-n- اتیل نفتیل -2، 7- سولفونامید) (pbns) برای اکسایش گزینشی الکل-های نوع اول و دوم و تبدیل آنها به گروه کربونیل مربوطه مورد استفاده قرار گرفته است. این کاتالیزگر به عنوان یک اکسنده سبز در واکنش های شیمیایی با بازده بالا، حداقل محصولات جانبی، زمان کوتاه، درشرایط بدون حلال و ملایم استفاده شده است. 2) در ادامه از این پلیمرعامل دارشده (pbns) به عنوان یک ک...
Probabilistic Boolean Networks (PBNs) are useful models for modeling genetic regulatory networks. In this paper, we propose efficient algorithms for constructing a sparse probabilistic Boolean network when its transition probability matrix and a set of possible Boolean networks are given. This is an interesting inverse problem in network inference and it is important in the sense that most micr...
Gene therapy offers the possibility to skip, repair, or silence faulty genes stimulate immune system fight against disease by delivering therapeutic nucleic acids (NAs) a patient. Compared other drugs protein treatments, NA-based therapies have advantage of being more universal approach designing because versatility NA design. NAs (siRNA, pDNA, mRNA) great potential for applications an immense ...
The activation of endothelium is important in recruiting neutrophils to sites of inflammation and in modulating their function. We demonstrate that conditioned medium from cultured, activated endothelial cells acts to significantly delay the constitutive apoptosis of neutrophils, resulting in their enhanced survival and increased phagocytic function. The antiapoptotic activity is, in part, attr...
Probabilistic Boolean networks (PBNs) have recently been introduced as a promising class of models of genetic regulatory networks. The dynamic behaviour of PBNs can be analysed in the context of Markov chains. A key goal is the determination of the steady-state (long-run) behaviour of a PBN by analysing the corresponding Markov chain. This allows one to compute the long-term influence of a gene...
MOTIVATION A key goal of studying biological systems is to design therapeutic intervention strategies. Probabilistic Boolean networks (PBNs) constitute a mathematical model which enables modeling, predicting and intervening in their long-run behavior using Markov chain theory. The long-run dynamics of a PBN, as represented by its steady-state distribution (SSD), can guide the design of effectiv...
