In Three-dimensional (3-D) image measurement field, pattern projection measurement methods based on the image intensity analysis are expected, because those can detect more numbers of stripes order by single projection. However, in the case when the intensity difference between stripes is narrow, the detecting of stripes order becomes difficult.In order to improve the detection accuracy of stri...

We present Inferential Power Analysis (IPA), a new class of attacks based on power analysis. An IPA attack has two stages: a profiling stage and a key extraction stage. In the profiling stage, intratrace differencing, averaging, and other statistical operations are performed on a large number of power traces to learn details of the implementation, leading to the location and identification of k...

OBJECTIVE Sphingosylphosphorylcholine (SPC) is an important lipid mediator that has been implicated in vascular disease. As it has not been studied in the pulmonary circulation, we examined its mechanisms of action in rat small intrapulmonary arteries (IPA). METHODS IPA were mounted on a myograph for recording tension and intracellular Ca2+ concentration ([Ca2+]i). Ca2+ sensitisation was exam...

BACKGROUND Pulmonary tuberculosis is occasionally confused with invasive pulmonary aspergillosis (IPA) in transplant recipients, since clinical suspicion and early diagnosis of pulmonary tuberculosis and IPA rely heavily on imaging modes such as computed tomography (CT). We therefore investigated IPA-mimicking tuberculosis in transplant recipients. METHODS All adult transplant recipients who ...

Two flow cytometric parameters are generally used to quantify platelet activation as measured by P-selectin (CD62) expression: percentage and mean channel fluorescence of CD62-positive platelets (%(+) and MCF(+), respectively). We describe a method for calculation of indices of platelet activation for positive (IPA(+)) and total (IPA(Sigma)) platelets, which reflect integrated amounts of CD62 e...

The large invasion plasmid of Shigella flexneri M9OT-W was used to generate recombinant plasmids carrying the ipaA, -B, -C, and -D genes, whose products are associated with the entry of the bacteria into colonic epithelial cells. Complete DNA sequences of ipaB, -C, and -D were determined. The proteins predicted (62, 42, and 37 kDa, respectively) from the nucleotide sequences lack a signal-pepti...

We formulate the importance sampling problem as a parametric minimization problem under the original measure and use a combination of infinitesimal perturbation analysis (IPA) and stochastic approximation (SA) to minimize the variance of the price estimation. Compared to existing methods, the IPA estimator derived in this paper has significantly smaller estimation variance and doesn’t depend on...

OBJECTIVE We hypothesized that primary care physicians (PCPs) specializing in a nonpharmaceutical/nonsurgical approach as their primary modality and utilizing a variety of complementary/alternative medicine (CAM) techniques integrated with allopathic medicine would have superior clinical and cost outcomes compared with PCPs utilizing conventional medicine alone. DESIGN Incurred claims and str...

BACKGROUND AND OBJECTIVES Despite improvements made in its early diagnosis and effective treatment, invasive pulmonary aspergillosis (IPA) remains a devastating opportunistic infection. In this retrospective study we have reviewed all consecutive cases of IPA diagnosed in adult patients with hematologic malignancies in our center from 1995 to 2000 to determine survival and prognostic factors. ...

This paper considers a sensitivity analysis in Hidden Markov Models with continuous state and observation spaces. We propose an Infinitesimal Perturbation Analysis (IPA) on the filtering distribution with respect to some parameters of the model. We describe a methodology for using any algorithm that estimates the filtering density, such as Sequential Monte Carlo methods, to design an algorithm ...
