A study of the angular distributions of leptons from decays of J/ψ’s produced in p-C and p-W collisions at √ s = 41.6 GeV has been performed in the J/ψ Feynman-x region −0.34 < xF < 0.14 and for J/ψ transverse momenta up to 5.4 GeV/c. The data were collected by the HERA-B experiment at the HERA proton ring of the DESY laboratory. The results, based on a clean selection of 2.3 · 10 J/ψ’s reconst...

We extend the special relativity into the superluminal case and firstly put forward a new superluminal theory of kinematics, in which we show that the temporal coordinate need exchanging with one of the spatial coordinates in a superluminal inertial frame, and that the coordinate transformations from any superluminal inertial frame to the rest frame (here rest just says in a relative sense) are...

Many sensor network applications feature bursty traffic patterns: after long periods of idle time with almost no network traffic, large amounts of data have to be transmitted reliably and in a timely manner. One example is volcano monitoring [5], where precious high-volume data is generated by rare volcanic eruptions. Unfortunately, existing MAC protocols do not sufficiently support such applic...

In this paper, we will provide a simple method for starting with a given finite frame for an $n$-dimensional Hilbert space $mathcal{H}_n$ with nonzero elements and producing a frame which is $epsilon$-nearly Parseval and $epsilon$-nearly unit norm. Also, the concept of the $epsilon$-nearly equal frame operators for two given frames is presented. Moreover, we characterize all bounded invertible ...

It is well-known that the sum of two $z$-ideals in $C(X)$ is either $C(X)$ or a $z$-ideal. The main aim of this paper is to study the sum of strongly $z$-ideals in ${mathcal{R}} L$, the ring of real-valued continuous functions on a frame $L$. For every ideal $I$ in ${mathcal{R}} L$, we introduce the biggest strongly $z$-ideal included in $I$ and the smallest strongly $z$-ideal containing ...

This paper presents an analysis and design method for human/robot integrated systems, especially for the cooperative sensing and operation of human and robot formations in human centered environments. The key for the human/robot formation integrated system is to create a common motion reference that can be understood by both human and the robots in the formation. The perceptive reference frame ...

In this chapter we survey several recent results on the existence of frames with prescribed norms and frame operator. These results are equivalent to Schur-Horn type theorems which describe possible diagonals of positive self-adjoint operators with specified spectral properties. The first infinite dimensional result of this type is due to Kadison who characterized diagonals of orthogonal projec...

Backgrounds Hypotrichosis with juvenile macular dystrophy (HJMD) is a rare genetic disorder caused from mutations in the Cadherin 3 (CDH3) gene. Results In the present study, we reported an Iranian family with three affected members born to a consanguineous parent. Mutational analysis using whole exome sequencing has revealed a nucleotide change in CDH3 gene (NM_001793:exon8:c.830delG) which l...
