The transmission of information relying on the perturbation of nonlinear oscillators vector fields can be approached in a unified manner. This can be accomplished by making use of the Information Transmission Via Control principle, which is stated and proved in the present work. In short, this principle establishes that any controller used to identically synchronize pairs of nonlinear oscillato...

Tobacco was transformed with a gene coding for an S-locus-specific glycoprotein of Brassica oleracea. The resulting transgenic plants showed tissue-specific and developmentally regulated expression of the introduced gene. lmmunolocaliration experiments showed that the Brassica gene was expressed in the stylar transmitting tissue of the transgenic plants. The pattern of expression of the introdu...

Objective. To explore midwives’ perceptions of developing their practice knowledge and skills, concerning maternal postnatal genital tract assessment (GTA); and to highlight how midwives pass on their practice knowledge and skills to student midwives. Design. A constructionist grounded theory methodology was employed to guide the design and processes. Ethical approval was gained from the region...

Alon, N., Transmitting in the n-dimensional cube, Discrete Applied Mathematics 37/38 (1992) 9-1 I. Motivated by a certain communication problem we show that for any integer n and for any sequence (a,,...,ak) of k = [n/21 binary vectors of length n, there is a binary vector z of length n whose Hamming distance from a, is strictly bigger than k-i for all 1 5 i 5 k. The n-dimensional cube is the g...

Information-theoretic secrecy is combined with cryptographic secrecy to create a secret-key exchange protocol for wireless networks. A network of transmitters, which already have cryptographically secured channels between them, cooperate to exchange a secret key with a new receiver at a random location, in the presence of passive eavesdroppers at unknown locations. Two spatial point processes, ...

Motivated by the fact that null-shell of a collapsing black hole can be described perfectly reflecting accelerating mirror, we investigate an extension this model to mirror semi-transparency and derive general implicit expression for corresponding Bogoliubov coefficients. Then, turn into explicit analytical form focusing on mirrors are accelerated via impulsive force. From so-obtained coefficie...

The current state of the RFC 3550 RTP/RTCP standard is not optimal for large-scale streaming sessions employing sourcespecific multicast and is currently the subject of research in many research laboratories. The most promising optimization for the RTP/RTCP protocol seems to be hierarchical aggregation [2], [3], [5], [6], [10], [11]. However, hierarchical aggregation has not yet completely solv...
