Recently, Chen and Deng (2009) proposed an interesting newmutual authentication protocol. Their scheme is based on a cyclic redundancy code (CRC) and a pseudo-random number generator in accordance with the EPC Class-1 Generation-2 specification. The authors claimed that the proposed protocol is secure against all classical attacks against RFID systems, and that it has better security and perfor...

BACKGROUND The ability and behaviour of the capture-recapture method using a virtual three-source model for evaluation of the level of completeness of case ascertainment requires exploration. METHODS Cancer cases obtained from 9 population-based cancer registries in Thailand during 2003 to 2007 were applied for capture-recapture using a model based on clinical, pathological and mortality data...

The increased functionality of EPC Class1 Gen2 (EPCGen2) is making this standard the de facto specification for inexpensive tags in the RFID industry. EPCGen2 supports only very basic security tools such as a 16-bit Pseudo-Random Number Generator and a 16-bit Cyclic Redundancy Code. Recently two EPCGen2 compliant protocols that address security issues were proposed in the literature. In this pa...

We show that the electron-phonon coupling (EPC) in many materials can be significantly underestimated by the standard density-functional theory (DFT) in the local-density approximation (LDA) due to large nonlocal correlation effects. We present a simple yet efficient methodology to evaluate the realistic EPC, going beyond the LDA by using more advanced and accurate GW and screened-hybridfunctio...

EPC (Electronic Product Code) tags are industry-standard RFID devices poised to supplant optical barcodes in many applications. They are prevalent in case and pallet tracking, and also percolating into individual consumer items and border-crossing documents. In this paper, we explore the systemic risks and challenges created by increasingly common use of EPC for security applications. As a cent...

Vascularization of bioartificial matrices is crucial for successful tissue engineering. Endothelial progenitor cells (EPC) have shown vascularization potential in ischemic conditions and may also support blood vessel formation in tissue-engineered matrices. The aim of our study was to investigate the impact of a well-characterized murine embryonal EPC line (T17b-EPC) on vascularization and fibr...

AIM To evaluate the effectiveness of the addition of epirubicin to conventional chemotherapy as a first-line therapy for stage III-IV epithelial ovarian cancer. MATERIALS AND METHODS A total of 132 patients who had undergone primary cytoreductive surgery between January 1998 and March 2003 were enrolled in the study. Twenty-four cases were excluded. Out of the remaining 108 subjects, 35 recei...
