In this paper, observer design problem for rectangular discrete-time singular systems with time-varying delay is discussed. Based on restricted system equivalent (RSE) transformations and by introducing new state vectors, the problem is transformed into observer design problem for time-varying delay discrete-time standard state-space systems. By Lyapunov function method and linear matrix inequa...

Introduction: Taking into account the growth of increase in the elderly population in Iran and the world, and the emergence of the phenomenon of feminization of aging, the present study has been conducted, with aim of examining the relationship between anxiety about aging and the perceived  and experienced gender inequality among the women of Shiraz city (Iran). Methods: This cross-sectional s...

We de ne a covariance-type operator on Wiener space: for F and G two random variables in the Gross-Sobolev space D of random variables with a square-integrable Malliavin derivative, we let ΓF,G:= ⟨ DF,−DL−1G ⟩ , where D is the Malliavin derivative operator and L−1 is the pseudo-inverse of the generator of the Ornstein-Uhlenbeck semigroup. We use Γ to extend the notion of covariance and canonica...

We define a covariance-type operator on Wiener space: for F and G two random variables in the Gross-Sobolev space D of random variables with a square-integrable Malliavin derivative, we let ΓF,G:= 〈 DF,−DL−1G 〉 where D is the Malliavin derivative operator and L−1 is the pseudo-inverse of the generator of the Ornstein-Uhlenbeck semigroup. We use Γ to extend the notion of covariance and canonical...

1 Similarity Metrics Many recommendation algorithms employ some form of similarity metric in the generation of ratings predictions. Similarity metrics are often associated with some form of distance measure. Definition 1.0.1. Let δ be a function δ : R × R → R. Let x,y, z ∈ R. Then δ is a distance measure if it satisfies the following four properties. (d1) δ(x,y) ≥ 0 (no negative distances). (d2...

We review three recovery algorithms used in Compressive Sensing for the reconstruction s-sparse vectors x ∈ CN from the mere knowledge of linear measurements y = Ax ∈ Cm, m < N. For each of the algorithms, we derive improved conditions on the restricted isometry constants of the measurement matrix A that guarantee the success of the reconstruction. These conditions are δ2s < 0.4652 for basis pu...

Based on both animal and human studies, inequality in food intake and social instability has adverse effects on the health of individuals and the community. However, it is not known whether social instability, food deprivation and food inequality affect neuronal death and premature aging in young animals. To address this question, the effects of these adverse situations, histopathological chang...

lentiviral vectors are promising gene delivery tools capable of transducing a variety of dividing and non-dividing cells, including pluripotent stem cells which are refractory for transduction by murine retroviruses. although there is a growing debate on the safety of lentiviral vectors for gene transfer, in particular for those derived from human immunodeficiency viruses, type one (hiv-1) and ...
