This paper presents an application of control theory and μ-analysis to stability analysis of optical communication networks. The network transfer matrix representation is used and simplified so that the propagation time-delay is isolated on a link-by-link basis. The optical network stability problem is reformulated as a robust stability problem. Sufficient stability conditions are developed by ...
In this manuscript, density functional theory was used to explore structural, vibrational and optical properties of the (Sc2O3)n (n=1-5) cluster systems using DFT/B3LYP/LanL2DZ level of computation. Different stable isomers were obtained and numerous chemical parameters such as HOMO-LUMO gap, ionization potential and electron affinity were calculated successfully. Stability of the clusters was ...
Bi-specific antibodies (BsAbs), which can simultaneously block 2 tumor targets, have emerged as promising therapeutic alternatives to combinations of individual monoclonal antibodies. Here, we describe the engineering and development of a novel, human bi-functional antibody-receptor domain fusion molecule with ligand capture (bi-AbCap) through the fusion of the domain 2 of human vascular endoth...
We prepared numbers of GeAsSe glasses and investigated their thermal stability and optical properties in order to search the best glasses with relatively high glass transition temperature Tg, strong structural stability, low optical loss and high optical nonlinearity. Through our systematical measurements, we concluded that the glasses with a mean coordination number around 2.45-2.5 are the bes...
during the last few decades cereals yield have increased drastically at the national level however, information about yield stability and its resistance to annual environmental variability are scare. in this study long term stability of grin yield of wheat, barley, rice, corn and overall cereals in iran were evaluated during a 40-year period (1971-2011). stability analysis was conducted using t...
Abstract The Venus flytrap is a fascinating plant with finely tuned mechanical bi-stable system, which can switch between mono- and bi-stability. Here, we combine geometrical design of compliant mechanics the function shape-memory polymers to enable switching bi- mono-stable states. Digital modelling using Chained Beam Constraint Model forecasted two geometries, were experimentally realized as ...
Coherent phononic oscillations in Bi and Ag nanowires were studied with a femtosecond pump-probe technique. In Bi nanowires laser pulses of 50 fs excited simultaneously acoustic oscillations at a frequency of about 9.5 GHz and optical phonons in the THz range. The transmission of nanowires on a glass substrate and the light scattered from free standing nanowires were measured. In Ag nanowires l...
Abstract Due to the instability and toxicity issues of lead/tin-based halide perovskites, lead-free metal perovskites have emerged as an attractive lead replacement for several semiconductor applications. Here, we present a bismuth (Bi)-based perovskite structure low-toxic potentially substitutable alternative lead-based solar cells. The synthesis optical performance MAPbI 3 , MA Bi 2 I 9 Cl x ...
