Hyperspectral Face Recognition with Adaptive and Parallel SVMs in Partially Hidden Face Scenarios.

Hyperspectral imaging opens up new opportunities for masked face recognition via discrimination of the spectral information obtained by hyperspectral sensors. In this work, we present a novel algorithm to extract facial spectral-features from different regions of interests by performing computer vision techniques over the hyperspectral images, particularly Histogram of Oriented Gradients. We have applied this algorithm over the UWA-HSFD dataset to extract the facial spectral-features and then a set of parallel Support Vector Machines with custom kernels, based on the cosine similarity and Euclidean distance, have been trained on fly to classify unknown subjects/faces according to the distance of the visible facial spectral-features, i.

Facilitating preemptive hardware system design using partial reconfiguration techniques.

In FPGA-based control system design, partial reconfiguration is especially well suited to implement preemptive systems. In real-time systems, the deadline for critical task can compel the preemption of noncritical one. Besides, an asynchronous event can demand immediate attention and, then, force launching a reconfiguration process for high-priority task implementation.

Structure-activity relationship of kahalalide F synthetic analogues.

Kahalalide F (KF) is a natural product currently under phase II clinical trials. Here, we report the solid phase synthesis of 132 novel analogues of kahalalide F and their in vitro activity on a panel of up to 14 cancer cell lines. The structure-activity relationship of these analogues revealed that KF is highly sensitive to backbone stereotopical modification but not to side chain size modification.

Wheel-running behavior is altered following withdrawal from repeated cocaine in adult rats.

The residual effects on open-field habituation and self-generated wheel running following withdrawal from repeated cocaine (COC; 30 mg/kg for 7 days) were examined in adult male rats. Control subjects received equivolumetric injections of saline (SAL) and were either allowed to feed ad libitum or pair-fed matched (PF SAL) to COC subjects to control for the drug's potential anorexic effect. Following 10 days of withdrawal, all subjects were examined twice on each of the two assessment instruments.

Standardized, mathematical model-based and validated in vitro analysis of anthrax lethal toxin neutralization.

Quantification of anthrax lethal toxin (LTx) neutralization activity (TNA) is pivotal in assessing protective antibody responses to anthrax vaccines and for evaluation of immunotherapies for anthrax. We have adapted and redesigned the TNA assay to establish a unifying, standardized, quantitative and validated technology platform for LTx neutralization in the J774A.1 murine cell line.
