A soft parameter function penalized normalized maximum correntropy criterion (SPF-NMCC) algorithm is proposed for sparse system identification. The proposed SPF-NMCC algorithm is derived on the basis of the normalized adaptive filter theory, the maximum correntropy criterion (MCC) algorithm and zero-attracting techniques. A soft parameter function is incorporated into the cost function of the t...

long exposure of uv radiation increases risk of skin diseases such as cancer and photoallergic reactions. uv-b (280-320 nm) radiation is mainly responsible for inducing skin problems. skin protection is a suitable method in the fight against ultraviolet radiation induced damage. various synthetic agents have been used as photo protective but because of their potential toxicity in humans, they h...

Specific Pathogen Free (SPF) embryonated eggs are used for the production of many veterinary and human vaccines. We have used High Throughput Sequencing to screen allantoic fluids and embryos for the presence of encapsidated viral genomes and viral transcripts, respectively. SPF eggs from two different producers were tested. We evidenced sequences corresponding to known endogenous retroviruses ...

The effect of infective, immunological, and irritative factors on the onset and development of silicosis after intratracheal inoculation with 50 mg of tridymite was investigated on 220 specific pathogen free (SPF) female Sprague-Dawley rats. Even after 12 months the rats, always kept in SPF conditions after intratracheal injection of the dust, showed mainly granulomas with little tendency to co...

abstract background and aims: vaccination of poultry has a major impact on the prevention and control of avian influenza viruses. nanobiotechnology techniques provide a new approach for improvement of influenza vaccine efficacy. in this study, efficacy of an inactivated nano-adjuvant vaccine developed based on an endemic h9n2 virus was evaluated in spf chickens. materials and methods: in each t...

To understand the perpetuation of inflammatory bowel disease (IBD), it is important to clarify whether the colitogenic CD4(+) T cells are self-limited effector or long-lived memory T cells. We here investigate the latency of colitogenic CD4(+) T cells in the remission stage of colitis under germfree (GF) conditions. We isolated splenic (SP) CD4(+) T cells from colitic CD4(+)CD45RB(high) T cell-...

The present study deals with the effects of alkaline and benzoyl chloride treatments sugar palm fibers (SPFs) on mechanical morphological properties SPF-reinforced poly(lactic acid) (PLA) composites. Seven different parameters SPFs were compared, which untreated, three solution concentrations 4%, 5%, 6% for treatment, 50 ml chloride-treated at soaking durations 10, 15, 20 min. Composites 30 wt....

Background: Recreational sun exposure has been associated with melanoma prevalence, and tourism settings are of particular interest for skin cancer prevention. Effective, affordable, and geographically flexible interventions to promote sun protection are needed. Objective: The aim of this study was to describe the protocol for a definitive randomized controlled trial (RCT) evaluating a smartpho...

This paper aims to study the surface morphology, flammability and tensile properties of sugar palm fiber (SPF) hybrid with polyester (PET) yarn-reinforced epoxy composite addition magnesium hydroxide (Mg(OH) 2 ) as a flame retardant. The composites were prepared by hybridized Mg(OH) /PET different amounts SPF contents (0%, 20%, 35% 50%) using cold press method. Then these tested horizontal burn...

Surface plasmon field-enhanced fluorescence (SPF) has been one of the powerful tools for biosensors and bioimaging. A wavelength-scale periodic structure coated with a thin metal film is called a plasmonic chip, and it can provide SPF. SPF of Cy5-streptavidin (Cy5-SA) was measured on a biotinylated plasmonic chip with a grating of 480 nm-pitch. The optimal structure of a plasmonic sensor-chip w...
