Ni-Zn ferrite/epoxy composites were investigated for embedded inductors. Ni-Zn ferrite power was prepared by a chemical coprecipitation method, and then modified with γ-glycidoxypropyl trimethoxysilane (KH-560). The unmodified ferrite was characterized by a powder X-ray diffraction (XRD) and vibrating sample magnetometer (VSM). The XRD curve showed… (More)
—This paper is concerned with a simple binary erasure-recovery coding scheme that falls into the family of so-called semi-random low-density-parity-check (SR-LDPC) codes. Based on a constrained random-scrambling technique, the proposed coding scheme is systematic, rateless, and capacity-achieving. We provide simulation examples comparing the new scheme with… (More)
SUMMARY In this letter we introduce new generalized cyclotomic sequences of order two and length pq firstly, then we determine the linear complexity and autocorrelation values of these sequences. Our results show that these sequences are rather good from the linear complexity viewpoint.
In this paper we propose an efficient Fair Exchange Signature Scheme(FESS) that allows two players to exchange digital signatures in a fair way. It may be considered as an interesting extension of concurrent signature presented in EURO CRYPT 2004 that is constructed from ring signatures. In our scheme, two unwakened signatures signed separately by two… (More)
BACKGROUND Chemokines, a group of small and structurally related proteins, mediate chemotaxis of various cell types via chemokine receptors. In mammals, seven different CXC chemokine receptors denoted as CXCR1 to CXCR7 have been reported. However, the chemokine receptor CXCR5 has not been reported in other vertebrates. RESULTS In the present study, the… (More)
