The inherent inflammability of epoxy resin (EP) has seriously limited its further application. structural design flame retardants huge potential for boosting the fire safety properties polymer materials. Herein, a novel MOFs-based hierarchical nanoarchitecture ([email protected]@SiO2) was constructed, composed ZIF-8 nanoparticles, as well in-situ grown phytic acid (PA) and silica. results indic...

A new decomposition for square matrices is constructed by using two known matrix decompositions. characterization of the core-EP order obtained this decomposition. We also use to investigate minus, star, sharp and core partial orders in setting complex matrices.

The intervertebral disc is a highly hydrated tissue that acts to absorb and distribute large complex loads placed on the spine. Diurnal loading and disc degeneration causes significant changes in water volume and proteoglycan content, which alters the internal osmotic environment. Short-term osmotic loading alters disc cell gene expression; however, the long-term effect of osmotic loading on di...

The problem of the resistive wall mode (RWM) is studied in cylindrical geometry and compared to experimental observations from HBT-EP tokamak. In HBT-EP, a dynamical RWM plasma response is studied by applying static, rotating and phase-flip external magnetic perturbations. The plasma response to the applied perturbation is included via the permeability matrix, P = 1/(−s+iα). Here, s is the norm...

We study the problem of semi-blind channel estimation and symbol detection in uplink multi-cell massive MIMO (multi-input multi-output) systems with spatially correlated time-varying channels. An algorithm based on expectation propagation (EP) is developed to iteratively approximate joint a posteriori distribution unknown matrix transmitted data symbols from an exponential family. This then use...

Within the NRQCD factorization approach the production of heavy quarkonia can be calculated in perturbative QCD in terms of a few production-processindependent NRQCD matrix elements. We test the universality of these longdistance matrix elements by comparing their values as determined from charmonium production at pp, ep, and ee colliders, and in Z, Υ, and B decays. a Heisenberg Fellow. CERN–TH...

Objective(s): In this study, we desvcribe a simple eco-friendly approach for the synthesis of a potent, stable and benign silver nanoparticles to carry and deliver chalcones and dihydrochalcones present in a methanol extract of Eysenhardtia polystachya (EP). Materials and Methods: In this process silver nanoparticles carring EP compounds (EP/AgNPs) are synthesized in a single step by eliminatin...

Multifunctional self-healing composites have great potential in several applications, i.e., from automotive to aerospace. This study examines the behavior of carbon fiber reinforced by depositing jet-spun cyclic olefin copolymer (COC) meshes on dry plies before lamination with epoxy resin (EP). Three different laminates were prepared, including neat EP/CF and two 4 wt.% 8 COC form a network as ...

We propose a new iterative detection and decoding (IDD) algorithm for multiple-input multiple-output (MIMO) based on expectation propagation (EP) with application to massive MIMO scenarios. Two main results are presented. first introduce EP iteratively improve the Gaussian approximations of both estimation posterior by detector soft output channel decoder. With this novel approach, denoted doub...

حاملگی خارج رحمی (ep) به لانه گزینی تخم بارور (زیگوت) در خارج از پوشش اندومتری رحم گفته می شود. با اینکه در اولین اتوپسی انجام شده در آمریکا (1638) علت مرگ ep بوده است ولی هنوز ep به عنوان یک مشکل باقی مانده است و در هیچ زمانی مثل حالا فکر پزشکان را به خود مشغول نکرده است . با اینکه میزان ابتلای به ep افزایش یافته است (به علت افزایش عوامل زمینه ساز) ولی از میزان مرگ و میر ناشی از ep کاسته شده ا...
