In this paper, we consider moving target detection and ranging for indoor sensing applications in urban environments. A simple method is used to determine the unambiguous range of an indoor moving target using dual frequency continuous wave (CW) radars. The dual-frequency radar employs two different carrier frequencies and simultaneously measures the phase change with respect to time, for each ...

The efficient and precise delivery of siRNA to target cells is critical to successful gene therapy. While novel nanomaterials enhance delivery efficiency, it still remains challenging for precise gene delivery to overcome nonspecific adsorption and off-target effect. Here we design a dual lock-and-key system to perform cell-subtype-specific recognition and siRNA delivery. The siRNA is self-asse...

conventional cytogenetic is the standard technique for detection of philadelphia (ph) chromosome in chronic myeloid leukemia (cml). evaluation of abelson murine leukemia/breakpoint cluster region (abl/bcr) fusion using dual-colour fluorescence in situ hybridization (d-fish) is an alternative approach allowing rapid and reliable detection of the disease. we employed the technique of interphase d...

The Dual-nu Support Vector Machine (SVM) is an effective method in pattern recognition and target detection. It improves on the Dual-C SVM, and offers competitive performance in detection and computation with traditional classifiers. We show that the regularisation parameters Dual-nu and Dual-C can be set such that the same SVM solution is obtained. We present the process of determining the rel...

OBJECTIVE To analyze a nationally representative sample of women for correlates of dual-contraceptive-method use. MATERIALS AND METHODS We conducted an analysis of the National Survey of Family Growth, 2006-2008, a cross-sectional survey of reproductive-aged women in the United States. RESULTS Dual method use was reported by 7.3% of the 5,178 women in the sample. Correlates of higher rates ...

We construct dual Lagrangians for G/H models in two space-time dimensions for arbitrary Lie groups G and H ⊂ G. Our approach does not require choosing coordinates on G/H, and allows for a natural generalization to Lie-Poisson duality. For the case where the target metric on G/H is induced from the invariant metric on G, the dual system is a gauged Higgs model, with a nonconstant metric and a co...

We argue that apart from the standard closed and open strings one may consider a third possibility that we call monodromic strings. The monodromic string propagating on a target looks like an ordinary open string (a mapping from a segment to the target) but its space of states is isomorphic to that of a closed string. It is shown that the monodromic strings naturally appear in T-dualizing close...

Instruction fetching is critical to the performance of a superscalar microprocessor. We develop a mathematical model for three different cache techniques and evaluate its performance both in theory and in simulation using the SPEC95 suite of benchmarks. In all the techniques, the fetching performance is dramatically lower than ideal expectations. To help remedy the situation, we also evaluate i...

OBJECTIVE The dual-therapy stent combines an abluminal biodegradable drug-eluting coating, with a 'pro-healing' luminal layer. This bioengineered layer attracts circulating endothelial progenitor cells that can differentiate into normal endothelium. Rapid endothelialisation of the stent might allow safe short dual antiplatelet therapy. We aim to assess clinical outcomes in patients treated with...
