Mobile Computing in Physics Analysis - An Indicator for eScience

This paper presents the design and implementation of a Grid-enabled physics analysis environment for handheld and other resource-limited computing devices as one example of the use of mobile devices in eScience. Handheld devices offer great potential because they provide ubiquitous access to data and round-the-clock connectivity over wireless links. Our solution aims to provide users of handheld devices the capability to launch heavy computational tasks on computational and data Grids, monitor the jobs status during execution, and retrieve results after job completion. Users carry their jobs on their handheld devices in the form of executables (and associated libraries). Users can transparently view the status of their jobs and get back their outputs without having to know where they are being executed. In this way, our system is able to act as a high-throughput computing environment where devices ranging from powerful desktop machines to small handhelds can employ the power of the Grid. The results shown in this paper are readily applicable to the wider eScience community.Comment: 8 pages, 7 figures. Presented at the 3rd Int Conf on Mobile Computing & Ubiquitous Networking (ICMU06.

Fine Needle Aspiration Cytology (FNAC) in the Management of Thyroid Pathology - The Aga Khan University Hospital Experience

Objective: To report the efficacy of FNAC in patients with thyroid disease.Methods: Between January 1990 and December 1994 the records of all patients treated surgically for thyroid disease at ENT Head and Neck Surgery of Aga Khan University were reviewed. All the patients had pre­operative FNAC as the first line of evaluation and the histopathologist examined post-operative thyroid specimen.Results: Forty-five patients (36 female and 9 male) had thyroid surgery. In 26 patients out of 45, FNAC was conclusive in diagnosing the nature of disease, while in 19 patients the FNAC was inconclusive because of the presence of follicular cell neoplasia.Conclusion: Our results indicate that the FNAC is very accurate and a reliable test in the diagnosis of thyroid pathology, however, to distinguish follicular adenoma from follicular carcinoma final histology is required. FNAC is cost effective method of evaluating thyroid pathology pre-operatively and plays a vital role in planning the surgical management of thyroid nodule OPMA 49:133, 1999)

Sub-Riemannian Fast Marching in SE(2)

We propose a Fast Marching based implementation for computing sub-Riemanninan (SR) geodesics in the roto-translation group SE(2), with a metric depending on a cost induced by the image data. The key ingredient is a Riemannian approximation of the SR-metric. Then, a state of the art Fast Marching solver that is able to deal with extreme anisotropies is used to compute a SR-distance map as the solution of a corresponding eikonal equation. Subsequent backtracking on the distance map gives the geodesics. To validate the method, we consider the uniform cost case in which exact formulas for SR-geodesics are known and we show remarkable accuracy of the numerically computed SR-spheres. We also show a dramatic decrease in computational time with respect to a previous PDE-based iterative approach. Regarding image analysis applications, we show the potential of considering these data adaptive geodesics for a fully automated retinal vessel tree segmentation.Comment: CIARP 201

Generation of Entangled N-Photon States in a Two-Mode Jaynes-Cummings Model

We describe a mathematical solution for the generation of entangled N-photon states in two field modes. A simple and compact solution is presented for a two-mode Jaynes-Cummings model by combining the two field modes in a way that only one of the two resulting quasi-modes enters in the interaction term. The formalism developed is then applied to calculate various generation probabilities analytically. We show that entanglement, starting from an initial field and an atom in one defined state may be obtained in a single step. We also show that entanglement may be built up in the case of an empty cavity and excited atoms whose final states are detected, as well as in the case when the final states of the initially excited atoms are not detected.Comment: v2: 5 pages, RevTeX4, minor text changes + 1 figure added, revised version to be published in PRA, May 200

COPD is associated with an increased risk of peripheral artery disease and mortality

Patients with chronic obstructive pulmonary disease (COPD) commonly present with multimorbidity. We aimed to investigate the association between COPD and the development of peripheral arterial disease (PAD) in the general population, and how this might affect mortality among individuals with COPD. We included 3123 participants of the population-based Rotterdam Study without PAD at baseline (mean age 65 years; 57.4% female). The association between COPD at baseline and PAD during follow-up was studied using logistic regression (PAD being indicated by an ankle–brachial index (ABI) of 0.9 or less). Cox regression was used for mortality analysis and interaction terms were used to investigate mortality risk modification by PAD. The presence of COPD was associated with incident PAD (adjusted odds ratio 1.9, 95% CI 1.1–3.2). Mortality rates per 100 000 person-years were as follows: 10.0 in individuals without COPD or PAD, 18.4 in those with COPD only, 16.1 in those with PAD only and 30.1 in individuals with both COPD and PAD. No statistical interaction was found between PAD and COPD on risk of dying. Individuals with COPD have an almost doubled risk of developing PAD. Although PAD does not modify the association between COPD and mortality, people suffering from both diseases have substantially higher mortality rates

Information loss in local dissipation environments

The sensitivity of entanglement to the thermal and squeezed reservoirs' parameters is investigated regarding entanglement decay and what is called sudden-death of entanglement, ESD, for a system of two qubit pairs. The dynamics of information is investigated by means of the information disturbance and exchange information. We show that for squeezed reservoir, we can keep both of the entanglement and information survival for a long time. The sudden death of information is seen in the case of thermal reservoir

A cross-center smoothness prior for variational Bayesian brain tissue segmentation

Suppose one is faced with the challenge of tissue segmentation in MR images, without annotators at their center to provide labeled training data. One option is to go to another medical center for a trained classifier. Sadly, tissue classifiers do not generalize well across centers due to voxel intensity shifts caused by center-specific acquisition protocols. However, certain aspects of segmentations, such as spatial smoothness, remain relatively consistent and can be learned separately. Here we present a smoothness prior that is fit to segmentations produced at another medical center. This informative prior is presented to an unsupervised Bayesian model. The model clusters the voxel intensities, such that it produces segmentations that are similarly smooth to those of the other medical center. In addition, the unsupervised Bayesian model is extended to a semi-supervised variant, which needs no visual interpretation of clusters into tissues.Comment: 12 pages, 2 figures, 1 table.
