Correlation Between Visual Prostate Symptom Score and Uroflowmetry Parameters in Patients with Benign Enlargement of Prostate (2017)

Background: Benign enlargement of prostate (BEP) needs treatment based on evaluation of symptom scoring among which International prostate symptom score (IPSS) is the standard one but carries difficulty in completion of the form. A visual prostate symptom score (VPSS) can evaluate the symptom with similar efficacy in a larger population with lower education.Aim of the study: The study was aimed to evaluate the correlation of the VPSS with uroflowmetry parameters.Materials and Methods. Men provisionally diagnosed as BEP were requested to complete the IPSS and VPSS, consisting of pictograms to evaluate urinary frequency, nocturia, force of the stream and quality of life. The maximum (Qmax) and average urinary flow rate (Qave), voided volume (VV) and post-void residual (PVR) urine volumes were measured. Statistical analysis was performed using the chi square test and Spearman's tests.Results. The study included 45 men (mean age 66 years, range 50-78 yrs.), with median prostate weight of 40 gm. One fourth of the patients were illiterate. Majority of the patients could complete VPSS without physician's assistance (46%). With mean voided volume of 273 ml, mean Qmax and Qave were 10.8 and 5.7, respectively. There was significant negative correlation of VPSS with Qmax (r=-0.435, p=0.003) and negative correlation of IPSS with Qmax, though insignificant (r=-0.1.05, p=0.4). Respective components of IPSS and VPSS also correlated significantly.Conclusion: The VPSS is equivalent to the IPSS in terms of correlation with uroflowmetry parameters and can therefore be used instead of the IPSS to evaluate LUTS in men with benign enlargement of prostate.JNGMC Vol. 13 No. 2 December 2015, page: 2-5

The coherence of kHz quasi-periodic oscillations in the X-rays from accreting neutron stars (2006)

We study in a systematic way the quality factor of the lower and upper kHz QPOs in a sample of low luminosity neutron star X-ray binaries, showing both QPOs varying over a wide frequency range. The sample includes 4U 1636-536, 4U 1608-522, 4U 1735-44, 4U 1728-34, 4U 1820-303 and 4U 0614+09. We find that all sources except 4U 0614+091 show evidence of a drop in the quality factor of their lower kHz QPOs at high frequency. For 4U 0614+091 only the rising part of the quality factor versus frequency curve has been sampled so far. At the same time, in all sources but 4U 1728-34, the quality factor of the upper kilo-Hz QPO increases all the way to the highest detectable frequencies. We show that the high-frequency behaviours of both the lower and upper kHz QPO quality factors are consistent with what is expected if the drop is produced by the approach of an active oscillating region to the innermost stable circular orbit: the existence of which is a key feature of General Relativity in the strong field regime. Within this interpretation, our results imply gravitational masses around 2 solar masses for the neutron stars in those systems.
Distributed Fiber-Optic Sensing and Integrity Monitoring (2010)

Structural health monitoring is a process meant to provide accurate and real-time information concerning structural condition and performance. Needs for structural health monitoring in the past two decades increased rapidly, and these needs stimulated the development of various sensing technologies. Distributed optical-fiber sensing technology has opened new possibilities in structural monitoring. A distributed deformation sensor (sensing cable) is sensitive at each point of its length to strain changes and cracks. Such a sensor practically monitors a one-dimensional strain field and can be installed over the entire length of the monitored structural members (suspension cables, bridge girders, tunnel vaults, dam basis, etc.). Therefore, the sensor provides for integrity monitoring, that is, direct detection, characterization (including recognition, localization, and quantification or rating), and report of local strain changes generated by damage. An integrity monitoring principle for long bridges and tunnels is developed. Various distributed sensing techniques are summarized, and their potential for the use in integrity monitoring is compared. Finally, the first large-scale, actual on-site application is briefly presented.
Linear classifiers in perceptron design (1996)

It is shown adaptive training of the nonlinear single layer perceptron can lead to seven different statistical classifiers: (1) Euclidean distance classifier; (2) standard Fisher linear discriminant function; (3) Fisher linear discriminant function, with pseudoinverse of the covariance matrix; (4) regularised discriminant analysis; (5) generalised Fisher discriminant function; (6) minimum empirical error classifier; and (7) maximum margin classifier and to intermediate ones. Which particular type of the classifier will be obtained depends on: 1) initialisation interval and its relation to the training data; 2) an initial value of the learning step; and 3) its change during the iteration process, the stopping criteria.
Semantically-smart disk systems (2006)

In this paper we describe research that has been on-going within our group for the past four years on semantically-smart disk systems . A semantically-smart system goes beyond typical block-based storage systems by extracting higher-level information from the stream of traffic to disk; doing so enables new and interesting pieces of functionality to be implemented within low-level storage systems. We first describe the development of our efforts over the past four years, highlighting the key technologies needed to build semantically-smart systems as well as the main weaknesses of our approach. We then discuss future directions in the design and implementation of smarter storage systems.
Theoretical Evaluation of S-Cone Pathway Sensitivity Losses In Diseases of The Visual System (1990)

Several recent studies have focused on the vulnerability of the S-cone pathway to visual system diseases. Selective or preferential S-cone pathway defects have been reported in diabetic retinopathy, age-related macular degeneration, retinitis pigmentosa, and glaucoma, to name but a few. Conclusions about Scone pathway defects in these disorders have been drawn from threshold versus wavelength measures ( i.e. , increment threshold spectral sensitivity), heterochromatic threshold versus radiance functions ( ala Stiles pi mechanisms), heterochromatic visual acuity under conditions where contrast favors S-cones, and flicker versus flashed heterochromatic increment thresholds. These various methods rely on the presumed high chromatic gain and coarse spacetime resolution of the S-cone pathway. 1-2
Imaging and qualitative depth analysis with a portable nonmydriatic fundus camera using oblique illumination (2023)

The photographic assessment of the optic nerve has been one of the original and most extensively used methods to evaluate patients for glaucoma. The depth evaluation of the optic disc in the retinal fundus is important for the early detection of glaucoma. Conventional fundus cameras have a limited field-of-view for imaging of the retina and its peripheral areas. In this article, we report the design and fabrication of a non-mydriatic wide-field fundus camera using a contact-free trans-scleral illumination that is capable of taking 3D images of the optic disc using oblique illumination. We demonstrate that, using oblique illumination through sclera, a quasi 3D image of the optic disc along with its shadow can be obtained. The shadow provides important information on the shape and depth of the optic disc. The depth values of the optic disc obtained by our proposed method using shadow length measurements are in good agreement with the values obtained using an optical coherence tomography device. The results indicate that our fabricated fundus camera could be an easy-to-handle and low-cost tool for remote detection and diagnosis of ocular diseases without the need of an ophthalmologist.
Practical device-centric WiFi/cellular link aggregation mechanism for mobile devices (2015)

One key enhancement in recent 3GPP cellular standard releases is WiFi/cellular network inter-operation and integration with protocols and techniques that can optimize target performance metrics. 3GPP specifications focus on network- centric solutions that require the involvement of the cellular operator in the WiFi/cellular connection and mobility management procedures. Even though this provides notable gains due to the centralized control, its implementation requires network upgrades and is relatively complex which limits the possibility of quick market penetration. In this work, we present a practical and effective device-centric WiFi/cellular link aggregation mechanism that can boost the download bit rate and minimize the download delay. The proposed mechanism is self-adaptive and achieves optimized aggregated download bit rate without the need for link quality estimation information, changes to the WiFi or cellular standards, or proxy server configuration. Moreover, it can be customized to support different service classes as shown for file downloading and video streaming applications. We do extensive testing using an experimental implementation over Android smartphones in order to demonstrate the practical feasibility of the proposed mechanism and to quantify its performance gains under different operational conditions.

Ectopic pregnancy with use of progestin-only injectables and contraceptive implants: a systematic review (2015)

Progestin-only contraceptive implants and injectables protect against ectopic pregnancy by being highly effective in preventing pregnancy overall; however, the absolute risk of ectopic pregnancy varies by type of progestin. Risk of ectopic pregnancy should not be a deterrent for use or provision of these methods.
Optimization of grating duty factor in gain-coupled DFB lasers with absorptive grating-analysis and fabrication (1992)

Grating duty factor strongly affects the performance of gain-coupled (GC) distributed feedback (DFB) laser diodes with an absorptive grating. Through numerical analysis the authors have found an optimum value in the duty factor for their low threshold operation. The minimum threshold gain achievable at this optimum duty factor is found to be almost independent of the order of the grating. According to this prediction, the authors have fabricated GaAlAs/GaAs GC DFB lasers with a third-order absorptive grating where the grating duty factor has been made close to the theoretical optimum value. In 200- mu m-long devices with both facets as-cleaved, low CW threshold current of 25 mA, external efficiency of 0.5 mW/mA, and SMSR as high as 45 dB have been obtained, which is qualitatively consistent with the analysis. High yield of single mode oscillation seems to be the result of the gain coupling.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
Seroepidemiology of measles in Addis Ababa, Ethiopia: implications for control through vaccination (2003)

We undertook a representative survey of measles antibodies in Addis Ababa, Ethiopia 1994, to characterize immunity and transmission. Specific-antibody levels (IU/l) were determined by ELISA for 4654 sera from individuals aged 0-49 years (1805 < 15 years) collected by stratified household-cluster sampling. The proportion seronegative (< 100 IU/l) was 20% (95% CI: 16-25) in children 9-59 months old, declining to 9% (7-12) in 5-9 year olds, 5% (4-7) in 10-14 year olds, and < 1% in adults. The proportion of children (< 15 years old) with low-level antibody (100-255 IU/l) was 8% (7-10). Vaccination and an absence of a history of measles illness were strongly associated with low-level antibody. History of measles vaccination in 9 months to 14-year-old children was approximately 80%. We estimate a primary vaccine failure rate of 21% (12-34) and continued high measles incidence of 22 per 100 susceptibles (19-24) per annum. Our data support the introduction of campaign vaccination in the city in 1998, although higher routine vaccine coverage is required to sustain the impact. The implications of a high prevalence of low-level antibody are discussed.
Multiscale Modeling of Streamers: High-Fidelity Versus Computationally Efficient Methods (2022)

View Video Presentation: https://doi.org/10.2514/6.2022-2124.vid A 2D axisymmetric streamer model is presented, using the fluid drift-diffusion approx- imation and the Hyridizable Discontinuous Galerkin (HDG) numerical method for spatial discretization. Numerical verification of the newly developed code is performed against the literature, demonstrating very good agreement with state-of-the-art codes, and results are presented for single-filament streamers using a plate-to-plate geometry, both with and without photoionization. Full-physics numerical models, such as the one presented, are computationally costly and not prone to parametrically studying streamers. Reduced order models of streamers are of interest to quantitatively relate streamer macroscopic parameters, but they need to be compared to higher-fidelity models to demonstrate their validity. In this contribution, the macroscopic parameter streamer model recently developed by our group is validated against the higher-fidelity model. The macroscopic parameter streamer model is based on the results of a reduced-order 1.5D quasi-steady model (i.e., 1D solution of the species continuity equations, 2D solution of Poisson equation, solved in the reference frame of the streamer). The comparison shows that the general trends captured by the macroscopic model, in terms of radius, speed, tip electric field and channel electric field relations, are in agreement with the results of the higher-fidelity simulations and limitations of the predictions are discussed.
Kalman filters predictive steps comparison for vehicle localization (2005)

The aim of this paper is to perform a comparison among several different Kalman filters algorithms designed for nonlinear systems. After presenting the most popular of them and showing its limitations, we introduce some new Kalman filters in order to compare them in the vehicle localization context. This comparison is based on the sole use of their predictive steps that corresponds to the worst case that it can occur in vehicle localization (corrective data are unavailable).
I am Anne Frank and This Is My Story (2020)

Biographies in form of graphic novels are currently very popular. In the EFL classroom biographical graphic novels are particularly suitable for CLIL history lessons as they are often located in historical contexts. The interplay of text and illustrations help make complex and demanding content more accessible and understandable to learners. This article will illustrate how to implement such a biographical graphic novel in a CLIL history lesson for students with A2/B1 level or aged 13-15. The focus will be on the graphic novel "Anne Frank's diary" by Ari Folman and David Polonsky. Concrete practical examples for the EFL classroom will be presented and analyzed.

Towards optimum planning of GMPLS transport networks (2006)

The rapid increase in the number of wavelengths per fiber has significantly increased the size of Optical Crossconnects (OXCs) in WDM transport networks. This calls for the use of Multi-Granular OXCs (MG-OXCs) to maintain the scalability of OXCs at a reasonable level. Various MG-OXC architectures and methods for the planning (or dimensioning) of MG-OXC-based networks have been proposed. Motivated by the fact that the MG-OXC constitutes only the optical segment of GMPLS-based transport node, we first propose a new transport node architecture that can handle the whole traffic hierarchy defined in GMPLS. Second, incorporating the proposed architecture with our novel contributions, namely (1) considering grouping and switching of the whole flows defined in GMPLS; (2) allowing bifurcation of multi-granularity traffic demands among different physical routes, requires defining a new transport planning problem, which we call the Routing and Multi-Granular Paths Assignment (RMGPA) problem. The RMGPA problem is formulated as a Mixed Integer Linear Programming (MILP) model with the objective of minimizing the overall network weighted port count.
Automated conformance evaluation of SystemC designs using timed automata (2010)

SystemC is widely used for modeling and simulation in hardware/software co-design. However, the co-verification techniques used for SystemC designs are mostly ad-hoc and non-systematic. A particularly severe drawback is that simulation results have to be evaluated manually. In previous work, we proposed to overcome this problem by conformance testing. We presented an algorithm that uses an abstract SystemC design to compute expected output traces, which are then compared with those of a refined design to evaluate its correctness. The main disadvantage of the algorithm is that it is very expensive because it computes the output traces offline and has to cope with non-deterministic systems. Furthermore, the designer has to compare the results manually with the outputs of a design under test. In this paper, we present an approach for efficient and fully-automatic conformance evaluation of SystemC designs. To achieve this, we first present optimizations of our previously proposed algorithm for the generation of conformance tests that drastically reduce computation time and memory consumption. The main idea is to exploit the specifics of the SystemC semantics to reduce the number of semantic states that have to be kept in memory during state-space exploration. Second, we present an approach to generate SystemC test benches from a set of expected output traces. These test benches allow fully-automatic test execution and conformance evaluation. Together with our previously presented model checking framework for abstract Sys-temC designs, we yield a fully-automatic HW/SW co-verification framework for SystemC that supports the whole design process. We demonstrate the performance and error detecting capability of our approach with experimental results.

High energy As ion implantation to GaAs (1995)

Over the last few years there have been many studies of GaAs layers grown in the temperature range from 180°C to 300°C called LT-GaAs. These studies were motivated by the potential applications of that material in microwave and fast optoelectronic devices. Annealed LT-GaAs layers have interesting electrical properties including high resistivity and short photocarrier lifetime connected with the nonstoichiometry of that material. However, it is still not clear whether arsenic antisite point defects or arsenic precipitates formed during annealing cause these interesting properties of LT GaAs. A second method of creating highly nonstoichiometric GaAs beside low temperature MBE growth is implantation with a high dose of arsenic. This method first applied two years ago showed that 200 keV arsenic ion implantation also leads to semi-insulating properties and that successive post-implantation annealing results in arsenic precipitate formation, similar to that observed in LT GaAs. Recently, more elaborate studies concerning photocarrier lifetime, resistivity, mobility and some structural characteristics were performed on GaAs implanted with high energy arsenic ions.
