We consider the problem of synthesis of data parallel and task parallel implementations of the scan also known as prefix sum. The user provides an example scan network as an input along with a partial program with missing array index expressions. We then manually extract the constraints for index expressions from the partial program such that the given example network is satisfied. Finally, the...

Previous methods for optimizing the scan times for PET transmission and emission scans under a total scan time constraint were based on linear non-statistical methods and used noise equivalent counts (NEC) criteria. The scan times determined by NEC analysis may be suboptimal when nonlinear statistical image reconstruction methods are used. For statistical image reconstruction, the predicted var...

Complete phosphorylation mapping of protein kinases was successfully undertaken using an automated LC/MS/MS approach. This method uses the direct combination of triple quadrupole and ion trapping capabilities in a hybrid triple quadrupole linear ion trap to selectively identify and sequence phosphorylated peptides. In particular, the use of a precursor ion scan of m/z -79 in negative ion mode f...

This article presents algorithms for temporal parallelization of Bayesian smoothers. We define the elements and operators to pose these problems as solutions all-prefix-sums operations which efficient parallel scan-algorithms are available. present general filtering smoothing equations, specialize them linear/Gaussian models. The advantage proposed is that they reduce linear complexity standard...

purpose: to describe a patient with eyelid sarcoidosis. case report: a 54 year-old patient was referred for an eyelid mass from 6 months ago.excisional biopsy showed inflammatory granuloma with tuton gaint cells. chest radiograph demonstrated bilateral hilar adenopathy, increased absorption on gallium scan was noted and bronchoalveolar lavage confirmed a diagnosis of sarcoidosis. treatment with...

purpose: to present 2 cases of acanthamoeba keratitis diagnosed by confocal scanning before positive results of smear and culture, and their successful treatment with combined medical therapy and corneal epithelial debridment. patients and findings: confocal scan was carried out in 2 contact lens wearers with a clinical diagnosis of acanthamoeba keratitis followed by corneal epithelial debridme...

bone scanning using the 99mtc-phosphate analogs is an established diagnostic modality and a commonly requested radioisotope examination for a variety of pathologies involving the skeleton, such as osteomyelitis, bony metastases, and occult fractures. the bone scan is one of the most commonly requested procedure in most nuclear medicine department. the images show areas of increased and decrease...

A stripping method for the determination of hypoxanthine in the presence of copper at the submicromolar concentration levels is described. The method is based on controlled adsorptive accumulation of hypoxanthine-copper at the thin-film mercury electrode followed by a fast linear scan voltammetric measurement of the surface species. Optimum experimental conditions were found to be the use of 1....

In this paper, we propose a new scheme for Built-In Self-Test (BIST) that uses an LFSR obtained by adding feedback loops to the IC boundary scan chain. This LFSR first generates random patterns to cover easy-to-test faults and after the random testing phase it is partially loaded with seeds to generate deterministic vectors for hard-to-test faults. The seeds are obtained by solving systems of l...
