In biometrics, it is crucial to detect impostors and thwart replay attacks. However, few researches have focused yet on the “liveness” verifi cation. This test ensures that biometric cues being acquired are actual measurements from a live person who is present at the time of capture. Here, we propose a speaker independent “liveness” verifi cation method for audiovideo identifi cation systems. I...

We present a steerable, electrostatic, untethered, MEMS micro-robot, with dimensions of 60 /j.m by 250 /j.m by 10 /j.m. This micro-robot is 1 to 2 orders of magnitude smaller in size than previous micro-robotic systems. The device consists of a curved, cantilevered steering arm, mounted on an untethered scratch drive actuator. These two components are fabricated monolithically from the same she...

It is currently thought that small RNA (sRNA) based repression mechanisms are primarily employed to mitigate the mutagenic threat posed by the activity of transposable elements (TEs). This can be achieved by the sRNA guided processing of TE transcripts via Dicer-dependent (e.g., siRNA) or Dicer-independent (e.g., piRNA) mechanisms. For example, potentially active human L1 elements are silenced ...

The thymus plays a critical role in the generation of immunocompetent T lymphocytes. In the thymus, lymphocytes are in close contact with epithelial cells, and this contact is necessary for T-cell maturation. Using cultured human thymic epithelial (TE) cells, we have found that human thymocytes bind to human TE cells in vitro. Thymocytes bound to both allogeneic and autologous TE cells and to t...

The aim of this study was to evaluate the efficacy and safety of transcatheter arterial chemoembolization (TACE) using warmed and nonwarmed miriplatin for hepatocellular carcinoma. Eighty patients (117 nodules), treated between January 2010 and June 2013, were evaluated. Thirty-two and 85 nodules were treated with nonwarmed and warmed miriplatin, respectively. The efficacy of TACE was evaluated...

Multi-Protocol Label Switching is useful in managing multimedia traffic when some links are too congested; MPLS Traffic Engineering is a growing implementation in today's service provider networks. In This paper we propose an improvement of MPLS-TE called EMPLS-TE, it is based on a modification of operation of Forwarding Equivalence Class (FEC) in order to provide the quality of service to stre...

BACKGROUND Toxoplasmic encephalitis associated with immune reconstitution inflammatory syndrome (TE-IRIS) is rarely described. METHODS To identify TE-IRIS cases, the authors performed a retrospective study of all HIV-infected patients diagnosed as having TE in our unit between January 2000 and June 2009, and a review of published cases. RESULTS Three patients out of 65 toxoplasmic encephali...
