An Improved GPS/RFID Integration Method Based on Sequential Iterated Reduced Sigma Point Kalman Filter

In this paper, an improved GPS/RFID integration method based on Sequential Iterated Reduced Sigma Point Kalman Filter (SIRSPKF) is proposed for vehicle navigation applications. It is applied to improve the accuracy, reliability and availability of satellite positioning in the areas where the satellite visibility is limited. An RFID system is employed to assist the GPS system in achieving high accuracy positioning. Further, to reduce the measurement noise and decrease the computational complexity caused by the integrated GPS/RFID, SIRSPKF is investigated as the dominant filter for the proposed integration. Performances and computational complexities of different integration scenarios with different filters are compared in this paper. A field experiment shows that both accuracy and availability of positioning can be improved significantly by this low-cost GPS/RFID integration method with the reduced computational load
A Non-dimensional Formulation of the Passive Bidomain Equation

Simulation studies of ST depression arising from subendocardial ischemia show a marked difference in the resulting epicardial potential distributions depending on which of the three common experimentally determined bidomain conductivity data sets is chosen. Here, the governing equation is rendered non-dimensional by dividing by the difference in normal and ischemic transmembrane potentials during the ST segment and by the sum of the intra and extracellular conductivities in the transverse direction, yielding the ratio of the sum of the intra and extracellular longitudinal conductivities divided by the sum of the intra and extracellular transverse conductivities as a dimensionless group. Averaging this ratio over the three sets of experimentally determined data gives the value of 3.21 ± 0.08. The effect of this narrow range means that the left hand side of the governing equation can be considered, as a good approximation, to be the same for all these sets of conductivity data. Hence, the right hand of the non-dimensional differential equation contains all the necessary information to compare the effect different conductivity data sets have on the epicardial potential distribution. As an example, an explanation is given as to why values from one data set gives rise to epicardial distributions which are markedly different from those obtained from the other two data sets.

Performance and Implementation Evaluation of TR PAPR Reduction Methods for DVB-T2

High Peak to Average Power Ratio (PAPR) is a critical issue in multicarrier communication systems using Orthogonal Frequency Division Multiplexing (OFDM), as in the Second Generation Terrestrial Digital Video Broadcasting (DVB-T2) system. This problem can result in large performance degradation due to the nonlinearity of the High Power Amplifier (HPA) or in its low power efficiency. In this paper, we evaluate the performance of different Tone Reservation-based techniques for PAPR reduction in DVB-T2 context. Also, we propose an iterative TR-based technique called "One Kernel One Peak" (OKOP). Simulation results and performance comparison of these techniques in terms of gain in PAPR reduction, mean power variation, and complexity will be given. Finally, we describe the implementation of a PAPR reduction algorithm in the DVB-T2 modulator.
Determination of ad hoc deposited charge on bare SOI wafers

This work develops an analytical model which correlates the changes of the threshold voltages in Pseudo-MOSFET structures with the charge intentionally placed on the surface of the native oxide. The model has been validated through experimental I-V characteristics obtained when the surface is physically altered with an APTES solution. The measurements were performed in 15 MESA isolated SOI cells. These results open the path for the potential use of the bare SOI wafers as a platform for charge-based sensing applications.
Multimodal and Mirror Invariant image description

This paper presents a novel local interest region description method named Multimodal and Mirror Invariant Local Pattern (MMILP) which is specially designed to be invariant to mirror and modality image variations. However, the proposed descriptor is also invariant to other image transformations such as rotation, scale, illumination. MMILP also avoids the dominant orientation calculation which is an intermediate step to normalize the rotation effect. Therefore, the descriptor building time is comparatively lower than the other local feature descriptors. The experimental results prove the efficiency and effectiveness of the proposed method. MMILP can also be used to classify the multimodal and mirror variant textures.
Reduced cardiovascular mortality risk in male smokers who are physically active. Results from a 25-year follow-up of the prospective population study men born in 1914.

OBJECTIVE To assess to what extent physical activity during leisure time may modify the mortality risk associated with smoking. METHODS Population-based cohort study in the city of Malmö, Sweden. The 642 men included in this study were all born in 1914 and were all free of cardiovascular disease at the baseline examination in 1968 and 1969. Smoking habits and physical activity during leisure time were assessed by a structured questionnaire. Main outcome measures were total and cardiovascular mortality rates during 25 years of follow-up. RESULTS The total and cardiovascular mortality rates in smokers were 33.2 per 1000 person-years and 15.9 per 1000 person-years, respectively. Corresponding figures in nonsmokers were 17.8 per 1000 person-years and 7.5 per 1000 person-years. Mortality rates in smokers were strongly related to daily tobacco consumption. Physically active men had lower overall (adjusted relative risk [RR], 0.7; 95% confidence interval [CI], 0.5-0.9) and cardiovascular (adjusted RR, 0.6; 95% CI, 0.3-0.9) mortality rates than sedentary men. Physically active men who never smoked (used as the control category) had the lowest death rate, and physically inactive smokers the highest (adjusted RR, 3.6; 95% CI, 2.1-6.3). The cardiovascular death rates in these 2 groups were 4.3 per 1000 person-years and 16.6 per 1000 person-years, respectively (adjusted RR, 5.5; 95% CI, 2.2-13.6). Vigorous physical activity in smokers was associated with an almost 40% lower cardiovascular mortality rate (RR, 0.6; 95% CI, 0.3-1.2; P = .11). CONCLUSIONS Regular physical activity was associated with lower total and cardiovascular mortality rates. Similar effects were observed in both nonsmokers and smokers.
Modalités de prise en charge de l’anorexie mentale en médecine de ville : enquête rétrospective auprès de 43 pédiatres exerçant en Seine-Maritime et dans l’Eure

Les preoccupations corporelles sont nombreuses au sein de notre societe, cependant, les cas d’anorexie mentale sont rares en medecine de ville. OBJECTIFS : L’objectif principal etait d’evaluer les modalites de prise en charge de l’anorexie mentale par les pediatres de ville et d’en apprecier la correlation avec les recommandations francaises et internationales. L’objectif secondaire etait d’estimer les difficultes rencontrees par les pediatres ainsi que les besoins de formation pour la prise en charge de cette pathologie. MATERIEL ET METHODE : Il s’agit d’une etude qualitative, retrospective, portant sur les pratiques des pediatres de ville de Seine-Maritime et de l’Eure, a partir d’un autoquestionnaire, ayant eu lieu de janvier a mai 2017. RESULTATS : Sur les 43 pediatres de ville de la region, 24 pediatres (55,8%) ont repondu au questionnaire, de facon totale ou partielle, 14 pediatres (32,6%) n’avaient jamais pris en charge de patient anorexique et les donnees etaient manquantes pour 5 pediatres (11,6%). Nous avons pu observer des disparites dans le prise en charge, notamment sur la frequence de suivi, la frequence des pesees ou la contre indication au sport, pour lesquelles les recommandations actuelles ne statuent pas. Toutefois, malgre des recommandations etablies sur d’autres parametres tels que les examens complementaires necessaires, la collaboration avec les dieteticiens, la prescription de complements alimentaires ou encore la prevention du syndrome de renutrition inappropriee, des difficultes persistent dans la prise en charge. Cependant, les pediatres de ville possedent de nombreux atouts et maitrisent les grands principes de prise en charge tels que la collaboration avec les pedopsychiatres ou le contrat de poids et connaissent parfaitement les criteres d’hospitalisation. De plus, ils rencontrent peu de difficultes de communication avec les patients et leur famille et ont peu de patients perdus de vue. Enfin, ceux-ci manifestent le souhait de prendre en charge ces patients malgre les difficultes rencontrees et sont demandeurs de formation. CONCLUSION : L’anorexie mentale est une pathologie complexe dont la prise en charge s’avere souvent difficile. Renforcer les liens entre les differents praticiens hospitaliers et le pediatre de ville est un enjeu majeur.
Gonadal Mosaicism Induced by Chemical Treatment of Sperm in Drosophila melanogaster

Accurate interpretation of forward genetic screens of chromosomes exposed in mature spermatozoa to a mutagenic chemical requires understanding—incomplete to date—of how exposed chromosomes and their replicas proceed through early development stages from the fertilized ovum to establishment of the germline of the treated male’s offspring. We describe a model for early embryonic development and establishment of the germline of Drosophila melanogaster and a model-validating experiment. Our model proposes that, barring repair, DNA strands modified by treatment with alkylating agents are stable and mutagenic. Each replication of an alkylated strand can result in misreplication and a mutant-bearing daughter nucleus. Daughter nuclei thenceforth replicate faithfully and their descendants comprise the embryonic syncytium. Of the 256 nuclei present after the eighth division, several migrate into the polar plasm at the posterior end of the embryo to found the germline. Based upon distribution of descendants of the alkylated strands, the misreplication rate, and the number of nuclei selected as germline progenitors, the frequency of gonadal mosaicism is predictable. Experimentally, we tracked chromosomes 2 and 3 from EMS-treated sperm through a number of generations, to characterize autosomal recessive lethal mutations and infer gonadal genetic content of the sons of treated males. Over 50% of 106 sons bore germlines that were singly, doubly, or triply mosaic for chromosome 2 or chromosome 3. These findings were consistent with our model, assuming a rate of misreplication between 0.65 and 0.80 at each replication of an alkylated strand. Crossing treated males to mismatch-repair-deficient females had no apparent effect on mutation rate.
Multiple emitter location and signal Parameter estimation

Processing the signals received on an array of sensors for the location of the emitter is of great enough interest to have been treated under many special case assumptions. The general problem considers sensors with arbitrary locations and arbitrary directional characteristics (gain/phase/polarization) in a noise/interference environment of arbitrary covariance matrix. This report is concerned first with the multiple emitter aspect of this problem and second with the generality of solution. A description is given of the multiple signal classification (MUSIC) algorithm, which provides asymptotically unbiased estimates of 1) number of incident wavefronts present; 2) directions of arrival (DOA) (or emitter locations); 3) strengths and cross correlations among the incident waveforms; 4) noise/interference strength. Examples and comparisons with methods based on maximum likelihood (ML) and maximum entropy (ME), as well as conventional beamforming are included. An example of its use as a multiple frequency estimator operating on time series is included.
The impact of unemployment insurance savings accounts on subsequent employment quality

The introduction of unemployment insurance savings accounts (UISA) in Chile in October 2002 led to more comprehensive unemployment protection while decreasing the opportunity cost of job change. Using a difference-in-differences approach this paper examines whether the introduction of UISA had an impact on the dierences in subsequent wages and contract types of (i) workers changing into a new employment, and (ii) workers experiencing a period of unemployment before re-entering the labour market. The analysis uses longitudinal social protection data and is the first to empirically investigate the effect of UISA on subsequent employment quality. The findings suggest that the introduction of the UISA scheme had a small negative effect on the wage difference of formal private sector workers, but no effect on contract types. Using informal private sector workers as a control group, only workers of the treatment group experiencing a period of unemployment show statistically different and positive results in wage growth. The robustness analysis, using an alternative "as if" introductory date and a different control group, largely supports these findings. The paper therefore concludes that the effect of UISA affiliation on wage growth is slightly negative, but positive compared to a control group for workers experiencing a period of unemployment, leading to a marginally higher employment quality for this latter group.
Efficient Indexing of Heterogeneous Data Streams with Automatic Performance Configurations

We study the problem of indexing continuous data streams in which data are heterogeneous in structure. Such data streams arise naturally in many real-life scenarios such as sensor networks. Our index structure uses bitmap based techniques to efficiently sketch the structures to allow space-efficient lossless archiving of the data stream. It also allows very fast query processing on the archived data stream. Furthermore, our index structure adapts to structural evolutions of the stream to ensure good indexing and querying performance both in space and time. We developed a cost-based optimization framework so the indexing engine adjusts its configuration at run-time to adapt to changes in the data stream. By means of linear feedback controllers, structural clustering and steepest gradient ascent optimization, our indexing engine can achieve excellent performance without any human intervention.
Prognostic implications of papillary thyroid carcinoma with tall-cell features.

BACKGROUND The prognostic implications of the diagnosis of a papillary thyroid carcinoma (PTC) with tall-cell features are unknown. METHODS All PTC patients identified between 1985 and 2005 were analyzed histologically. Classical PTC cases were defined as having <30% tall cells, PTC with tall-cell features (PTC TCF) as 30%-49% tall cells, and tall-cell variant of PTC (TCV) as ≥ 50% tall cells. All classical PTC, PTC TCF, and TCV ≥ 1 cm in size were included. RESULTS A total of 453 patients satisfied the inclusion criteria (288 classical PTC, 31 PTC TCF, and 134 TCV). Classical PTC patients were younger than their PTC TCF and TCV counterparts (p<0.0002). There was an increase in tumor size from classical PTC to PTC TCF and TCV (p=0.05). Extensive extrathyroid extension and positive margins were more often present in TCV and PTC TCF than in classical PTC (p=0.0001 and p=0.03 respectively). Overall pathologic tumor (pT) stage was more advanced in TCV and PTC TCF than in classical PTC (p<0.0001). Total thyroidectomy and radioactive iodine therapy were more often performed and administered in TCV patients than in their PTC TCF and classical PTC counterparts (p=0.001 and p=0.0001 respectively). Median follow-up was 9.3 years. Ten-year disease-specific survival (DSS) was lower in TCV (96%) and PTC TCF (91%) than in classical PTC (100%; p<0.001). Ten-year distant recurrence-free survival (RFS) was higher in classical PTC (98%) than in PTC TCF (89%) and TCV (96%; p=0.03). In multivariate analysis, the presence of more than five positive nodes and extranodal extension were the only independent prognostic factors of neck and distant RFS respectively. Four (2.4%) of 165 PTC TCF and PTC TCV developed poorly differentiated or anaplastic carcinoma in their recurrence, while none of the 288 classical PTC transformed into higher grades (p=0.017). CONCLUSIONS PTC TCF and TCV have similar clinicopathologic features that are more aggressive than classical PTC. PTC TCF and TCV have similar DSS and distant RFS but poorer outcomes than classical PTC. PTC TCF are currently being treated like classical PTC, that is, less aggressively than TCV. PTC TCF and TCV TCV have a higher rates of high-grade transformation than classical PTC. Consideration should be given to using a 30% tall-cell threshold to diagnose TCV.
A model to explain visits to the doctor: with specific reference to the case of Israel.

W HEN do people see a doctor? At one extreme, blatant pathology and extreme pain will, with few exceptions, bring one to a doctor in those societies where doctors are available (with the possible exception of mental illness). At the other extreme, a small portion of the visits are accounted for by a preventive health orientation, where no symptoms have been perceived. But, as Zola points out (1966, 1968), "we find that the vast bulk [of a physician's load] is concerned with quite minor disorders. " There is, on the other hand, he notes, a great body of data which show that there is much illness, defined as such both clinically and subjectively, which is not brought to the attention of the physician. What Zola is saying, then, is that the potential for entry into patienthood is extraordinarily widespread and continuous. One can be ill, clinically speaking, without going to the doctor; or one can go to the doctor, either without any particular change in one's clinical condition or even without any particular justification from the point of view of the physician. If variations among individuals, social subgroups, or societies in visiting rates cannot be explained, within limits, by variations in clinically-determinable morbidity, what are the factors that can predict such variations? It is the purpose of this paper to present a model which. though derived from the case of Israel, should be applicable to other societies as well.
Increased interstitial concentrations of pyruvate and lactate in the trapezius muscle of patients with fibromyalgia: a microdialysis study.

OBJECTIVE The aim of this study was to compare the interstitial concentrations of pyruvate, lactate and glutamate in the trapezius muscle between patients with fibromyalgia syndrome and healthy controls. DESIGN Comparative cross-sectional study. SUBJECTS Patients with fibromyalgia (n = 19) and healthy controls (n = 19); all women. METHODS Subjects answered a questionnaire about different aspects of pain. Pressure pain thresholds over the trapezius and tibialis anterior muscles were determined. The inter-stitial concentrations of pyruvate, lactate and glutamate were determined in the resting trapezius muscle by the microdialysis technique, with samples collected every hour for 5 consecutive hours. Pain intensity was also rated. RESULTS Significantly higher interstitial concentrations of pyruvate and lactate were found in patients with fibromyalgia- syndrome. The multivariate regression analyses of group membership and pressure pain thresholds of the trapezius confirmed the importance of pyruvate and lactate. CONCLUSION Different mechanisms that may increase pyruvate and lactate in patients with fibromyalgia syndrome are discussed. Improved understanding of peripheral muscle alterations in patients with fibromyalgia syndrome could lead to mechanism-based rehabilitation.
Fitness and Training THE INFLUENCE OF PRE-TEST ANXIETY, PERSONALITY AND EXERCISE ON VO2max ESTIMATION

THE INFLUENCE OF PRE-TEST ANXIETY, PERSONALITY AND EXERCISE ON VO2max ESTIMATION. Heather M. Hunn, Peter T. Lapuma, Daniel T. Holt. JEPonline. 2002;5(1):514. This research investigated the influence of exercise activities, situational factors, and personality on a submaximal cycle ergometry test (SCET). Data were collected via a questionnaire administered to 193 active duty Air Force members during their required annual SCET. Multiple regression and ANOVA were used to find the relative influence of each factor on the estimated maximal rate of oxygen uptake (VO2max) determined by the SCET. For the group as a whole, self-reported test anxiety explained 24% of the variance in SCET results, while self-reported aerobic caloric expenditure explained only 10%. For runners, test anxiety explained 26%, and calories expended running explained only 5%. For cyclists, calories expended cycling explained 53% of the variance, while test anxiety had no influence on SCET results. The results indicate that for non-cyclists, high test anxiety results in an underestimation of VO2max as determined by the SCET. The exercise that has the greatest influence on increasing SCET scores is cycling. Increased time or intensity spent running does not significantly enhance SCET performance.
Evaluation of a combined anaerobic and aerobic system for the treatment of slaughterhouse wastewater

A laboratory scale anaerobic/aerobic (An/Ar) system, comprising an anaerobic filter (AF) coupled to an aerobic sequential batch reactor (SBR), was developed to treat wastewater from a slaughterhouse. The AF operated with organic loadings (OL) from 3.7 to 16.5 kg m−3 d−1 and a hydraulic retention time (HRT) ranging from 16 to 72 h. The efficiency of chemical oxygen demand (COD) removal was between 50 and 81% and was shown to be related inversely to the value of the OL. The production rate of methane was in the region of 411 mL per g of COD removed. On the other hand, the degradation of organic matter (OM) by an aerobic pathway in the SBR followed first‐order kinetics with regard to OM concentration; 85% of the remaining OM from the AF was eliminated within 6 h of aeration, and over 95% of total OM was eliminated as COD within 9 h. The optimal treatment conditions in this system were found at OL = 11.0 kg m−3 d−1 and HRT = 24 h in the AF, whereas the SBR was most efficient at 9 h of aeration.
Mesure des tendances comportementales d'approche/évitement : le rôle des processus sensorimoteurs

Ces travaux portent sur les processus a l’œuvre dans la reactivation des tendances comportementales d’approche et d’evitement. Dans cette these, nous defendons l’idee que la reactivation de ces tendances comportementales depend de l’information sensorimotrice presente et de sa similarite avec l’information sensorimotrice passee ayant ete associee a des comportements d’approche/evitement. Dans une premiere partie, nous avons teste si reproduire dans la tache d’approche/evitement l’information sensorimotrice (en l’occurrence, visuelle) la plus representative de l’approche/evitement permettait une meilleure reactivation de ces tendances comportementales. A travers huit experiences, nous avons pu montrer que lorsque l’information visuelle de la tache etait representative, les effets d’approche/evitement etaient plus forts que lorsque cette information visuelle n’etait pas presente. Qui plus est, les effets produits lorsque cette information etait presente etaient forts et replicables. Dans les deux parties suivantes, nous avons teste l’hypothese selon laquelle la reactivation des tendances a l’approche/evitement depend de specificites personnelles associees au comportement des individus. A travers sept experiences, nous avons pu montrer que les tendances d’approche/evitement reactivees variaient en fonction de caracteristiques personnelles, theoriquement associees au comportement reel des individus envers des groupes sociaux et envers un produit de consommation. De maniere generale, ces travaux sont coherents avec l’idee que la reactivation des tendances a l’approche/evitement prend sa base sur l’information sensorielle ayant accompagne ces actions passees
