The results of noise immunity studies signal structures based on signals with orthogonal frequency multiplexing (OFDM signals) for multipath propagation and in the presence additive spectrum-focused interference (SFI) are presented. It has been shown that algorithms receiving these constructs SFI compensation, essence which is non-linear processing input implementations by limiting or switching...

We determined the effect of N-acetylcysteine (NAC) on the expression of the phosphorylated p38 (p-p38) protein and superoxide anion generation (SAG), two important players in the processing of neuropathic pain, in the lumbosacral spinal cord of rats with chronic constriction injury (CCI)-induced neuropathic pain. The sciatic functional index (SFI) was also measured to assess the functional reco...

OBJECTIVE Accurate assessment of lupus flares is critical but problematic in clinical trials. This study examined the impact of modifications to the classic Safety of Estrogens in Lupus Erythematosus National Assessment (SELENA)-SLEDAI flare index (cSFI). METHODS Ninety-one SLE patient records were evaluated at two visits at which the SLEDAI and BILAG had been scored prospectively. The cSFI w...

INTRODUCTION Exposure to secondhand smoke (SHS) increases children's risk of acquiring chest and ear infections, tuberculosis, meningitis and asthma. Smoking bans in public places (where implemented) have significantly reduced adults' exposure to SHS. However, for children, homes remain the most likely place for them to be exposed to SHS. Additional measures are therefore required to protect ch...

Executing untrusted code while preserving security requires that the code be prevented from modifying memory or executing instructions except as explicitly allowed. Software-based fault isolation (SFI) or “sandboxing” enforces such a policy by rewriting the untrusted code at the instruction level. However, the original sandboxing technique of Wahbe et al. is applicable only to RISC architecture...

Some mycoses are endemic. They develop through hematogenous spread, causing a generalized infection, usually with secondary mucosal involvement.The aim of this observational and retrospective study was to report the prevalence characteristics oral lesions in patients diagnosed systemic fungal infections (SFI) over 25-year period southern Brazil. Demographic (age, sex, ethnicity, occupation) cli...

Objective(s):  The aim of this study was to evaluate the final outcome of nerve regeneration across the eggsell membrane (ESM) tube conduit in comparison with autograft. Materials and Methods: Thirty adult male rats (250-300 g) were randomized into (1) ESM conduit, (2) autograft, and (3) sham surgery groups. The eggs submerged in 5% acetic acid. The decalcifying membranes were cut into four pie...

Upper limb motor fatigability is an important debilitating factor for activities of daily living in clinical pediatric populations. However, the reliability protocols these populations currently unknown. Therefore, current study investigates test-retest a static and dynamic protocol grip pinch strength typically developing children (TDC). Eighty-nine TDC (35 boys, 54 girls; mean age 10 years 11...

Pilings in a lipid sea T etraspanin contains a tightly packed quartet of transmembrane helices, according to a new, high resolution electron microscopy structure deduced by Min et al. (page 975). The rigid tetraspanin proteins may thus act as stable pilings in a lipid sea, say the authors. Tetraspanins associate with a number of important transmembrane proteins such as integrins to form distinc...
