In this paper a new Linear Matrix Inequality (LMI) based switching controller for multiple Bottleneck packet switching Network has been considered. The main goal is to illustrate the effects of the Switching Control methodology on the congestion control problem of the packet switching Networks with dynamically varying parameters such as Link capacity and time delays. The congestion dynamic for ...
Salicylic acid (SA) is an important hormone involved in many diverse plant processes, including floral induction, stomatal closure, seed germination, adventitious root initiation, and thermogenesis. It also plays critical functions during responses to abiotic and biotic stresses. The role(s) of SA in signaling disease resistance is by far the best studied process, although it is still only part...
Systemic induction of pathogenesis-related (PR) proteins in tobacco, which occurs during the hypersensitive response to tobacco mosaic virus (TMV), may be caused by a minimum 10-fold systemic increase in endogenous levels of salicylic acid (SA). This rise in SA parallels PR-1 protein induction and occurs in TMV-resistant Xanthi-nc tobacco carrying the N gene, but not in TMV-susceptible (nn) tob...
این آزمایش روی گلهای شاخه بریده رز رقم ‘ردنائومی’ و ‘آوالانج’ با طول 40 سانتی متر، به مدت 18 ساعت بصورت تیمار کوتاه مدت(پالسینگ) بر پایه آزمایش کاملاً تصادفی با 5 تیمار شیمیایی: ساکارز + هیدروکسی کوئینولین سولفات (suc+hqs) ، ساکارز+ هیدروکسی کوئینولین سولفات+ سالسیلیک اسید(suc+hqs+sa)، ساکارز+ هیدروکسی کوئینولین سولفات+ آسکوربیک اسید (suc+hqs+asa) ، ساکارز + هیدروکسی کوئینولین سولفات+ سالسیلیک ا...
Female (n = 5,226) and male (n = 5,969) U.S. Navy recruits completed a survey assessing their premilitary histories of adult sexual assault (SA), defined as attempted or completed rape since the age of 14. The survey was completed under anonymous or identified conditions. Overall, 39% of women reported premilitary SA victimization and 13% of men admitted premilitary SA perpetration. As predicte...
In plants, necrotic lesions occur at the site of pathogen infection through the hypersensitive response, which is followed by induction of systemic acquired resistance (SAR) in distal tissues. Salicylic acid (SA) induces SAR by activating NONEXPRESSER OF PATHOGENESIS-RELATED GENES1 (NPR1) through an oligomer-to-monomer reaction. However, SA biosynthesis is elevated only slightly in distal tissu...
in this paper, we study different methods of solving joint redundancy-availability optimization for series-parallel systems with multi-state components. we analyzed various effective factors on system availability in order to determine the optimum number and version of components in each sub-system and consider the effects of improving failure rates of each component in each sub-system and impr...
OBJECTIVE To evaluate the impact of second semen analysis (SA) on a treatment decision in infertile men with varicocele and abnormal first SA. DESIGN Retrospective chart review. SETTING University hospital. INTERVENTION None. MAIN OUTCOME MEASURE(S) Standard clinical semen analysis. PATIENT(S) A total of 160 infertile men with varicocele and abnormal first SA were evaluated. Two SA we...
A saturable absorber is a nonlinear functional material widely used in laser and photonic nanodevices. Metallic nanostructures have prominent saturable absorption (SA) at the plasmon resonance frequency owing to largely enhanced ground state absorption. However, the SA of plasmonic metal nanostructures is hampered by excited-state absorption processes at very high excitation power, which usuall...
