Fecal excretion of a nonenveloped DNA virus (TTV) associated with posttransfusion non‐A‐G hepatitis

Five patients with type B or C hepatocellular carcinoma were found to be infected with a nonenveloped DNA virus (TTV) associated with posttransfusion hepatitis of non‐A–G etiology. Paired feces and serum samples from these patients were tested for TTV DNA by polymerase chain reaction with seminested primers and their sequences were compared. TTV DNA was detected in sera from all of the patients, while it was detected in feces from three patients, including two with high viral titers in serum. When feces and serum from one patient were subjected to floatation ultracentrifugation in CsCl, TTV in feces banded at a peak density of 1.35 g/cm3 and that in serum at 1.31–1.32 g/cm3. TTV isolates in three pairs of feces and serum had the identical sequence of 222 base pairs. The excretion of TTV into feces indicates that TTV would be transmitted not only parenterally but also nonparenterally by a fecal–oral route. J. Med. Virol. 56:128–132, 1998. © 1998 Wiley‐Liss, Inc.
[The reliability and validity of the Turkish Version of the World Health Organization Quality of Life Instrument-Older Adults Module (WHOQOL-Old)].

PURPOSE To determine the psychometric properties of the Turkish version of the World Health Organization Quality of Life Instrument-Older Adults Module (WHOQOL-Old). METHODS The Turkish version of the WHOQOL-OLD was administered to 527 older (> 65 years) adults living in urban, suburban, and rural areas of Manisa Province, Turkey. The WHOQOL-OLD module consists of 24 items assigned to 6 facets (sen------sory abilities, autonomy, past, present and future activities, so-cial participation, death and dying, and intimacy) and is a supplementary module of WHOQOL-BREF. The WHOQOL-BREF and GDS-30 were also administered to the participants. A confirmatory approach was used during reliability and validity analysis. SPSS v.10. 0 and LISREL v.8. 54 were used for analysis. RESULTS Mean age of the participants was 71.06 +/- 5.20 years and the overall WHOQOL-OLD score was 56.02 +/- 11.86. In all, 54.5% of the participants were female and 60.5% reported to be in poor health. Both ceiling and floor effects of the WHOQOL-OLD were satisfactory (< 0.05%). Alpha values for the facets and overall scale (range: 0.68-0.88) (> 0.70), and item total correlations and overall scale success were satisfactory. As a measure of the construct validity of the scale, confirmatory factor analysis showed very high CFI values (range: 0.936-0.999) for each of the domains. Convergence of WHOQOL-OLD facet scores on WHOQOL-BREF domains and WHOQOL-OLD were very fine in general. CONCLUSIONS The psychometric properties of the Turkish version of the WHOQOL-OLD were acceptable, indicating that the scale is reliable and valid for use with older Turkish adults (> 65 years).
Effects of maternally transferred organochlorine contaminants on early life survival in a freshwater fish

Laboratory research has shown that female fish can pass toxic organochlorines (OCs) from their bodies to their eggs, killing their offspring if sufficient quantities are transferred. We conducted a controlled incubation study using gametes from a wild, OC‐contaminated walleye (Sander vitreus) population (Bay of Quinte, Lake Ontario, Canada) in order to assess among‐female variation in offspring early life survival in relation to ova concentrations of planar OCs (polychlorinated dibenzo‐p‐dioxins and furans and planar polychlorinated biphenyls) and a suite of other maternal and ova characteristics. Equal volumes of ova from each female were fertilized, pooled, and incubated together as an experimental cohort. Relative survival of each female's offspring was estimated as the proportion of surviving larvae (at ∼5 d posthatch) that she contributed to the cohort as determined by microsatellite DNA parentage assignment. Total planar OC concentration (expressed as toxic equivalency of 2,3,7,8‐tetrachloro‐dibenzo‐p‐dioxin) of ova was positively related to maternal age and size and to ova lipid content. However, early life survival did not decline with increasing ova planar OC concentrations. Similarly, we observed no significant relationships between early life survival and ova thiamine content, ova fatty acid composition, or maternal age or size. Early life survival was more strongly correlated with date of spawn collection, thyroid hormone status of the ova, and ovum size. Maternally transferred planar OCs do not appear to negatively influence female reproductive success in this walleye population.
Development and validation of Indian Affective Picture Database.

Since culturally salient stimuli for emotion recognition are scarce in India, we developed and validated a set of 140 coloured pictures of six basic emotions along with a neutral expression. The expressions were posed by four expressers, two males and two females, with mean age of 25.25 (SD 3.77) years. The expressions were captured from five different angles keeping the background uniform. These pictures were shown to 350 undergraduates who labelled the emotion and rated their intensity. The mean biased hit rate was 93.02 (SD 7.33) and mean unbiased hit rate was . 519 (SD .015). Within subjects ANOVA revealed significant main effect of emotion (F(1, 6) = 7.598, p < . 001). The t-test value (23.116, p < .001) shows that the given emotion was identified correctly by participants beyond chance factors. The mean intensity rating was 5.94 (SD .77). Overall, the results reveal that the pictures are a valid set of affective stimuli.

Headspace analysis of volatile metabolites of Pseudomonas aeruginosa and related species by gas chromatography-mass spectrometry

Gas chromatographic-mass spectrometric analysis of headspace volatiles was performed on cultures of 11 strains of Pseudomonas aeruginosa and 1 strain each of Pseudomonas cepacia, Pseudomonas putida, Pseudomonas putrefaciens, Pseudomonas fluorescens, and Pseudomonas maltophilia. All strains of Pseudomonas aeruginosa produced a distinctive series of odd-carbon methyl ketones, particularly 2-nonanone and 2-undecanone, and 2-aminoacetophenone. The other strains failed to produce 2-aminoacetophenone. Two sulfur compounds, dimethyldisulfide and dimethyltrisulfide, were present in strains of P. aeruginosa and in variable amounts in other species. Butanol, 2-butanone, 1-undecene, and isopentanol were also detected in P. aeruginosa cultures.
Validation of Spaceborne and Modelled Surface Soil Moisture Products with Cosmic-Ray Neutron Probes

The scale difference between point in situ soil moisture measurements and low resolution satellite products limits the quality of any validation efforts in heterogeneous regions. Cosmic Ray Neutron Probes (CRNP) could be an option to fill the scale gap between both systems, as they provide area-average soil moisture within a 150–250 m radius footprint. In this study, we evaluate differences and similarities between CRNP observations, and surface soil moisture products from the Advanced Microwave Scanning Radiometer 2 (AMSR2), the METOP-A/B Advanced Scatterometer (ASCAT), the Soil Moisture Active and Passive (SMAP), the Soil Moisture and Ocean Salinity (SMOS), as well as simulations from the Global Land Data Assimilation System Version 2 (GLDAS2). Six CRNPs located on five continents have been selected as test sites: the Rur catchment in Germany, the COSMOS sites in Arizona and California (USA), and Kenya, one CosmOz site in New South Wales (Australia), and a site in Karnataka (India). Standard validation scores as well as the Triple Collocation (TC) method identified SMAP to provide a high accuracy soil moisture product with low noise or uncertainties as compared to CRNPs. The potential of CRNPs for satellite soil moisture validation has been proven; however, biomass correction methods should be implemented to improve its application in regions with large vegetation dynamics.
Comparison of direct sequence spread spectrum rake receiver with a maximum ratio combining multicarrier spread spectrum receiver

This paper presents a theoretical analysis of the performance of a filter bank-based multicarrier spread spectrum (FB-MC-SS) system. In FB-MC-SS, each data symbol is spread across multiple subcarriers, but - contrary to some other systems - there is no spreading in time. The results of this system are then compared with those of the well-known direct sequence spread spectrum (DS-SS) system with a rake receiver for its best performance. We compare the two systems when the channel noise is white. We prove that as the processing gains of the two systems tend to infinity both systems approach the same performance. However, numerical simulations show that in practice, where processing gain is limited, FB-MC-SS outperforms DS-SS.

Effect of parameter variation in UTBB FDSOINCFET

In this work we have investigated the performance of UTBB FDSOI-NCFET with different dielectric and gate materials. Variation in ION/IOFF and subthreshold swing with these parameters has also been studied. Effect of varying ferroelectric properties such as coercive field and remanent polarization has been demonstrated. The basic idea here is to find out an optimum configuration for dielectric and gate materials which should be used so as to get better performance of the device. We have validated our simulation using TCAD simulator. Here, we have taken PZT (Lead zirconium titnate) as a ferroelectric material because it possesses many advantages like high dielectric constant and nano-second polarization reversal. This device is a unique amalgamation of Negative capacitance transistor and FDSOI. Negative capacitance provides low subthreshold swing and FDSOI ensures suppression of short channel effects and hence UTBB FDSOI-NCFET is a viable candidate for future low power transistors.
ParaSite: mining the structural information on the World-Wide Web

The World-Wide Web is potentially the world’s largest knowledge base but only if new information retrieval techniques are developed to take advantage of its unique characteristics, particularly the semi-structured information within pages, across pages, and in page names. Because these types of structure are represented in such different ways, a large number of specialized tools have been required to gather structural information. I provide a relational database interface to the Web called Squeal, which encapsulates these different types of structure in a uniform manner, allowing the user to query the Web in Structured Query Language (SQL) as if it were a database. A novel “just-intime” interpreter automatically retrieves information from the Web as implicitly demanded by user queries, a technique which could be applied not just to the Internet but to other sources of data too large to be precomputed into a database. The level of abstraction provided by Squeal allows the user to easily create agents that make full use of the previously-untapped information on the Web. One such “ParaSite” is a simple structure-based recommender system that compares favorably to the best text-based system.

An Analytical Method to Generate Walking Pattern of Humanoid Robot

An analytic method to generate the real-time trajectory of the center of mass (CoM) is proposed for given zero moment point (ZMP) pattern. The whole walking process is divided into transient and periodic walking phases. For each phase of walking, we compute the analytic solution of the center of mass for given ZMP based on the inverted pendulum model. Specially, for the transient walking phase, we actively utilize the non-minimum phase solution to extract the center of mass trajectory. The proposed pattern generation method were implemented to a real humanoid robot system called by MAHRUII. Those are verified by the experiments.
Measuring the Efficiency Effect of Banning Anti-Microbial Growth Promoters: The Case of Danish Pig Production

This study examines the effect of banning antimicrobial growth promoters on efficiency in the production of weaned and slaughter (finishing) pigs. We focus on the reaction of producers and production efficiency. We evaluate the estimated output and input shadow prices relative to market prices to analyse producer reactions and capture the impact on production efficiency by evaluating the effects of the ban changes on total factor productivity. To this end we model a multi product shadow profit function and incorporate output and input related shadow prices by using a second order flexible functional form. The development in total factor productivity is subsequently measured by calculating the Malmquist index on the farm level. To make infer-ences on the effect of banning growth promoters over time we regress in a second estimation step the changes in total factor productivity on potential explanatory factors by applying a bootstrapped censored regression procedure. Our results suggest that there was no effect of the ban on total factor productivity due to outputs and inputs substitution. Breeding pigs are pro-duced at the expense of weaned and finisher pigs. Feed input is over utilised relative to other inputs. The high shadow prices for substituting outputs are associated with better export mar-ket prices. These findings may have critical implications for the slaughtering plants with over capacity.
Fault Location in Power Distribution Systems using ANFIS Nets and Current Patterns

The electric power markets have imposed new power service quality that make fault location in power distribution systems a mandatory issue. In this paper, a fault location approach based on the current waveforms measured at the power substation, the knowledge of protective device settings and ANFIS nets is presented. As a result, the approach may locate the faulted zone by using current descriptors. As a result, the ANFIS nets have proved the capability to locate the fault in a specific zone of the power distribution system. Result shows validation errors lower than 1% to locate faulted zones

The ‘Historiated’ Neolithic Stele of Saint-Samson-sur-Rance (Côtes-d'Armor, France)

The stone of Saint-Samson is a Neolithic stele of 70 tons and 10 m of probable length. Its intriguing leaning position and its very regular morphology have aroused curiosity since medieval times. Three of its four faces—oriented towards the cardinal points—display engravings that were discovered in the 1970s. Now, a new recording protocol has combined 2D techniques for emphasizing the contrast of the engravings (oblique rotating lights) and 3D methods for restoring the volumes of the support (photogrammetry, structured-light scanner). The results obtained have made it possible to implement the first structural analysis of the stone. The north and west faces show an opposition between domestic (cattle, goats) and wild animals (suidae, cervidae, birds, cetaceans), depicted confronted and with their horns or tusks clearly visible. The south face was reserved for the human figure and for iconic artefacts (polished axe, throwing stick, ring disk, steering oar). The four faces have in common the presence of boats. The relationship linking the monument to waterways and the sea is approached by analysing both local legends and the phenomenon of the tidal wave.
Raw light field image compression of sliced lenslet array

A light field image is a sampling of the intensity and direction of the light rays crossing the optical lens of a digital light field camera. Processing of the light field information captured by a camera is necessary for rendering images of the scene to the final user at a given focal plane or viewpoint. In the area of light field imaging, several compression techniques are currently under research in order to foster the development of novel applications. An analysis of raw light field image compression of sliced lenslet array is presented in this paper. The distortion introduced by compression is measured in terms of peak signal-to-noise ratio and the structural similarity index. The obtained results are finally discussed.
Sharing Control With Haptics

Objective: Haptic shared control was investigated as a human–machine interface that can intuitively share control between drivers and an automatic controller for curve negotiation. Background: As long as automation systems are not fully reliable, a role remains for the driver to be vigilant to the system and the environment to catch any automation errors. The conventional binary switches between supervisory and manual control has many known issues, and haptic shared control is a promising alternative. Method: A total of 42 respondents of varying age and driving experience participated in a driving experiment in a fixed-base simulator, in which curve negotiation behavior during shared control was compared to during manual control, as well as to three haptic tunings of an automatic controller without driver intervention. Results: Under the experimental conditions studied, the main beneficial effect of haptic shared control compared to manual control was that less control activity (16% in steering wheel reversal rate, 15% in standard deviation of steering wheel angle) was needed for realizing an improved safety performance (e.g., 11% in peak lateral error). Full automation removed the need for any human control activity and improved safety performance (e.g., 35% in peak lateral error) but put the human in a supervisory position. Conclusion: Haptic shared control kept the driver in the loop, with enhanced performance at reduced control activity, mitigating the known issues that plague full automation. Application: Haptic support for vehicular control ultimately seeks to intuitively combine human intelligence and creativity with the benefits of automation systems.
Comparison of effects of propranolol and metoprolol on airways obstruction in chronic bronchitis.

show any abnormality. Carcinoma of the breast was diagnosed and a mammogram was performed. This showed a large circular mass with increased density, homogeneous and with well-demarcated borders, compressing the surrounding breast tissue. There was no thickening of the skin. Aspiration produced from a tense cyst about 70 ml of chocolate-coloured fluid containing flakes of tissue. About 50 ml of air was injected and a contrast mammogram was taken with the patient erect.2 It showed a fluid level and confirmed the diagnosis of a cyst (figure). This was removed intact leaving a rim of atrophied breast tissue. Macroscopically the cyst was very tense, globular, and of about 10 cm in diameter. The outer wall was shaggy. It was multiloculated and contained chocolate-coloured fluid with whitish tissue debris. Histologically it was a typical epidermal cyst lined with stratified squamous epithelium and the cavity contained laminated layers of keratin.
Optical modeling of light trapping in thin film silicon solar cells using the FDTD method

In this paper we present our recent work on modeling the light propagation in silicon thin film solar cells. The aim is to create a realistic view of the light trapping effects and of the resulting optical generation rate. The focus is on real three dimensional systems. Our software Sentaurus TCAD, developed by Synopsys, has the ability to import real topography measurements and to model the light propagation with the Finite-Difference Time-Domain method (FDTD).
Neural Network Dynamics Models for Control of Under-actuated Legged Millirobots

Millirobots are a promising robotic platform for many applications due to their small size and low manufacturing costs. However, controlling these millirobots is difficult due to their underactuation, power constraints, and size. While hand-engineered controllers can sometimes control these millirobots, they often have difficulties with highly dynamic maneuvers and complex terrains. We present a learning based approach in which a model of the dynamics is learned from data gathered by the millirobot, and that data is then leveraged by an MPC controller. We show that with 17 minutes of random data collected with the VelociRoACH millirobot, the VelociRoACH can accurately follow trajectories at higher speeds and on more difficult terrains than a differential drive controller.

Ground effect experiments and model validation with Draganflyer X8 rotorcraft

Ground effect on rotary aircraft has been studied for many decades. Although a large body of research results is now available for conventional helicopters, this topic is just beginning to receive attention in the unmanned aerial vehicle community, particularly for small size UAVs. The objective of this paper is to assess the applicability of a widely-used ground effect model, developed in the middle of last century, for predicting the ground effect on a small rotary UAV. The particular vehicle employed in this work, the Draganflyer X8, is actuated by 8 propellers arranged in 4 coaxial pairs in a quadrotor configuration and is currently employed for the development of autonomous landing capabilities for UAVs. The aforementioned ground effect model gives an explicit relationship between the thrust produced by a single propeller while operating in-ground-effect and the thrust out-of-ground effect, as a function of the normalized propeller height above ground. A series of experiments was conducted with the propellers of the vehicle on a test stand, and with the X8 vehicle in flight, from which we obtained the in-ground and out-of-ground thrusts. Juxtaposition of our results against the theoretical model points to a stronger ground effect on the X8 vehicle than predicted by theory. Discussion of the assumptions underlying the theory and the experimental procedures and their implications on the results obtained is also included in the paper.
