wireless communication is the major form of connection nowadays. in most cases it exploits the benefits of the spread spectrum techniques to overcome channel introduced corruptions like doppler residual frequency, noise, interference and jamming. these techniques also enhance the security and quality of the link. using long spreading pseudo-noise codes provides further security for the link tho...

Consider independent long range percolation on Z2, where horizontal and vertical edges of length n are open with probability pn. We show that if lim supn→∞ pn > 0, then there exists an integer N such that PN (0 ↔ ∞) > 0, where PN is the truncated measure obtained by taking pN,n = pn for n ≤ N and pN,n = 0 for all n > N .

BACKGROUND Anti-peanut immunoglobulin E (anti-Pn IgE) can persist throughout life, suggesting that this condition could be maintained by long-lived antibody-secreting cells (ASCs). To determine the role of long-lived ASCs, peanut-allergic mice underwent prolonged treatment with the proteasome inhibitor, bortezomib (Bz). METHODS Intravenous Bz was given twice weekly for 21 weeks to peanut-alle...

Compared to enteral or hypocaloric oral nutrition, the use of PN (parenteral nutrition) is not associated with increased mortality, overall frequency of complications, or longer length of hospital stay (LOS). The risk of PN complications (e.g. refeeding-syndrome, hyperglycaemia, bone demineralisation, catheter infections) can be minimised by carefully monitoring patients and the use of nutritio...

Cyber criminals may abuse open wireless networks or those with weak encryption for cyber crimes. Assume surveillance has identified suspect traffic such as child porn downloading traffic on the Internet. To locate such criminals, law enforcement has to first identify which mobile (MAC) is generating suspect traffic behind a wireless router. The challenge is how to correlate the private wireless...

The use of long-term parenteral nutrition (PN) in children with significant gut failure has been associated with progressive cholestatic liver disease (1–4). Progression to liver cirrhosis and end-stage liver disease are well-known consequences of long-term dependence on PN. The etiology of liver disease related to PN administration seems to be multifactorial (1–3). There is evidence linking th...

Protease nexin-1 (PN-1), a member of the serpin superfamily, controls the activity of extracellular serine proteases and is expressed in the brain. Mutant mice overexpressing PN-1 in brain under the control of the Thy-1 promoter (Thy 1/PN-1) or lacking PN-1 (PN-1-/-) were found to develop epileptic activity in vivo and in vitro. Theta burst-induced long-term potentiation (LTP) and NMDA receptor...

Long-term parenteral nutrition (PN) can induce intestinal atrophy, leading to a loss of epithelial integrity in the small intestines. This change may alter the intestinal permeability of vancomycin (VCM), a non-absorbable antibiotic. The aim of the present study was to investigate the effect of PN on the pharmacokinetics of VCM in rats. VCM was intravenously (5 mg/kg) or intraduodenally (20 mg/...

The cardiac extracellular matrix is a dynamic structural support network that is both influenced by, and a regulator of, pathological remodeling and hypertrophic growth. In response to pathologic insults, the adult heart reexpresses the secreted extracellular matrix protein periostin (Pn). Here we show that Pn is critically involved in regulating the cardiac hypertrophic response, interstitial ...
