let ‎x be an ‎‎n-‎‎‎‎‎‎square complex matrix with the ‎cartesian decomposition ‎‎x = a + i ‎b‎‎‎‎‎, ‎where ‎‎a ‎and ‎‎b ‎are ‎‎‎n ‎‎times n‎ ‎hermitian ‎matrices. ‎it ‎is ‎known ‎that ‎‎$vert x vert_p^2 ‎leq 2(vert a vert_p^2 + vert b vert_p^2)‎‎‎$, ‎where ‎‎$‎p ‎‎geq 2‎$‎ ‎and ‎‎$‎‎vert . vert_p$ ‎is ‎the ‎schatten ‎‎‎‎p-norm.‎ ‎‎ ‎‎in this paper‎, this inequality and some of its improvements ...

objectives: joint attention is one of the most important prerequisite of language and social development. there are two types of joint attention, initiating joint attention and responding to joint attention. this study examined the development of responding to joint attention in typically developing children in 8-30 month. methods: this study was cross-sectional. 61 children (40 female and 20 m...

The paper proposes a simple approximated method for calculation of voltage sags in an electrical network. Following the general method for symmetrical (three-phase) fault calculations based on the use of the bus impedance matrix of the network, the paper illustrates the construction of a square matrix that, under acceptable assumptions, directly provides voltage drops (sags) at each node of the...

Artificial intelligence (AI) applications are often faulted for their brittleness and slowness. In this paper, we argue that both of these problems can be ameliorated if the AI program is context-sensitive, making use of knowledge about the context it is in to guide its perception, understanding, and action. We describe an approach to this problem, context-mediated behavior (CMB). CMB uses cont...

background: there is little information about blood supply of the carpal joint in one- humped camel, while there is extensive data about cow and equine species. in order to perform surgeries and diagnostic techniques in carpal region, information about the elements of the joint such as its arteries is necessary. objectives: this study aims at describing the origins, arrangements, and branches o...
