Programmable optical unitary matrices (POUMs) in photonic integrated circuits (PICs) technology play a critical role modern information technology. With the expansion of their scale and integration density, POUMs have performance limited by fabrication errors tuning phase building blocks, i.e., tunable 2 × couplers. Here, we provide an in-depth theoretical analysis prior robust equivalent coupl...

Recently Phys. Rev. E 68, 016116 (2003)]] proposed an alternative way to compute numerically the fluctuation-dissipation ratios in nonequilibrium critical systems. Using well-known facts of nonequilibrium critical dynamics I show that the leading contributions of the quantities they consider are in fact one-time quantities which are independent of the waiting time. The ratio of these one-time q...

Background: In vitro maturation is a good method to decrease cancer risk of superovulation by gonadotropin hormones. A paracrine effect of oocyte secretions on oocyte developmental competence is under investigation. Apart from oocyte maturation, ovulation in vivo requires a precise control of extracellular matrix modification. Cumulus cells secrete hyaluronan to form a muco-elastic extracellula...

For the anisotropic [u( ∑N i=1 φ 2 i ) 2+v ∑N i=1 φ 4 i ]-theory with N = 2, 3 we calculate the imaginary parts of the renormalization-group functions in the form of a series expansion in v, i. e., around the isotropic case. Dimensional regularization is used to evaluate the fluctuation determinants for the isotropic instanton near the space dimension 4. The vertex functions in the presence of ...

models of living in cities needs planning for land use. those who have planned for the cities have studied land use to present a model for the construction of cities. change of land use, is the main concern today. the factors which affect the change in land use can be divided into three main groups: legal factors, economical factors and population. out of these three factors, population has bee...

Population rate or activity equations are the foundation of a common approach to modeling for neural networks. These equations provide mean field dynamics for the firing rate or activity of neurons within a network given some connectivity. The shortcoming of these equations is that they take into account only the average firing rate, while leaving out higher-order statistics like correlations b...
