Thesimulation and analysis of large complex systems,have become easier by using model reduction technique. In thispaper, the authorsutilized Balanced Truncation (BT) method of modelreduction and is found to be competitive to other Model Order Reduction(MOR) approaches.Further, the same is implemented on Texas Instruments’ TMS320C54xxprocessor. The suitability of the method is illustrated by sol...

This paper focuses on reducing the power consumption of wireless microsensor networks. Therefore, a communication protocol named LEACH (Low-Energy Adaptive Clustering Hierarchy) is modified. We extend LEACH’s stochastic clusterhead selection algorithm by a deterministic component. Depending on the network configuration an increase of network lifetime by about 30 % can be accomplished. Furthermo...

It was recently reported that human umbilical endothelial vein cells (HUVECs) transdifferentiate and express cardiac genes when co-cultured with rat neonatal cardiomyocytes (Condorelli et al. (2001)). If substantiated and optimized, this phenomenon could have many therapeutic applications. We re-investigated the HUVEC-rat neonatal cardiomyocyte co-culture system but detected cardiomyocyte marke...

In [HNa] the submitters generalize the BMGL generator in order to allow keystream synchronization with random access properties. This synchronization is done by an initialization vector. Furthermore they present a sketch for a security proof based on the assumption that the iterated Rijndael mapping is hard to invert even if an attacker has a number of extra plaintext-ciphertext pairs. In [HNb]...

OBJECTIVE Unrestricted somatic stem cells (USSCs) were successfully identified from human cord blood. However, the efficacy of USSC transplantation for improving left ventricular (LV) function post myocardial infarction (MI) is still controversial. METHODS AND RESULTS PBS, 1x10(6) human fibroblasts (Fbr), 1x10(5) USSCs (LD), or 1x10(6) USSCs (HD) were transplanted intramyocardially 20 minutes...

This study demonstrates, by using neutral comet assay and pulsed field gel electrophoresis, that hyperosmotic stress causes DNA damage in the form of double strand breaks (dsb). Different solutes increase the rate of DNA dsb to different degrees at identical strengths of hyperosmolality. Hyperosmolality in the form of elevated NaCl (HNa) is most potent in this regard, whereas hyperosmolality in...

Fimbriae of Porphyromonas gingivalis are filamentous appendages on the cell surface and are thought to be one of the virulence factors. The fimA gene encoding the subunit protein of fimbriae, fimbrillin (FimA), was classified into four typeable variants (types I to IV). We previously examined the distribution of P. gingivalis in terms of fimA genotypes in periodontitis patients using a fimA typ...

BACKGROUND Autoimmune neutropenia of infancy is caused by neutrophil-specific autoantibodies. Primary AIN is characterized by neutrophil count < 500 ml and a benign self-limiting course. Detecting specific antibodies against the polymorphic human neutrophil antigen usually confirms the diagnosis. Current available tests, however, are expensive and inapplicable in many laboratories as they requi...

We consider time-harmonic scattering by penetrable polygonal obstacles in 2D. We present a boundary element method (BEM) based on a hybrid numerical-asymptotic (HNA) approximation space built from oscillatory basis functions. The basis functions are carefully chosen to capture the leading order terms in the highfrequency asymptotic behaviour of the boundary solution. Numerical experiments sugge...
