Network service provisioning in UWB open mobile access networks

An innovative architecture to access information transport resources under short-term market conditions is presented. Ultra-wideband (UWB) technology in the centralized wireless access domain is believed to minimize the intrinsic performance limitations of the radio link and to provide flexible access in a very wide range of data rates of over 100 Mb/s, even in a strong multipath environment. The decoupling of user, infrastructure, and service provision in an open mobile access network (OMAN) is proposed to overcome current limitations of radio-based networks. A solution for the joint management of quality-of-service and mobility in the UWB domain is proposed, under the assumption of a resource management compliant with the differentiated services framework. Moreover, a model for the "commoditization" of the network service is introduced. The commodity is identified as the transfer of information units between two end points of the network, measured by a function of the so-called "virtual delay," that summarizes the parameters characterizing the performance of the transfer service. A description is given of this model, together with the definition of a pricing law to charge improved Internet protocol-based services. Such concepts are central in the end-to-end service set-up.
Finite Element Analysis Animated Simulation of Velopharyngeal Closure

Objective To use finite element analysis animated simulations to investigate factors affecting velopharyngeal closure. Design A coronal section multicomponent finite element analysis model of a human soft palate was created in Simulia Abaqus 6.5–1 from high resolution WIR I images of a single adult female subject, interpreted by reference to published anatomic dissections. Tissues were assigned hyperelastic property coefficients for neo-Hookean behavior, with gravity at 9.8 ms–2 in the y-axis. Vector forces based on estimations in previous publications were applied throughout levator veli palatini and palatopharyngeus muscles, using a nonlinear analysis algorithm, to produce animated simulations of velopharyngeal space closure. Variation of levator veli palatini angle from 60° to 49°, the contribution of palatopharyngeus muscle, and the effect of submucous cleft were investigated for their effects on velopharyngeal closure. Results The animated simulations showed anthropomorphic behavior and supported the previously suggested effects of the levator veli palatini angle, with reduced effectiveness of velopharyngeal closure as levator veli palatini angle decreases. Palatopharyngeus action reduced the efficiency of closure for a levator veli palatini angle of 60°, and a submucous cleft reduced this for both our normal subject and for a levator veli palatini angle of 60°, but both palatopharyngeus action and a submucous cleft enhanced closure for a levator veli palatini angle of 49°. Conclusions This study advances soft palate finite element analysis to a real-subject-based multicomponent hyperelastic model that demonstrates anthropomorphic behavior. Animated simulations using the model demonstrate the possible effects of levator veli palatini angle, a submucous cleft, and the contribution of the palatopharyngeus.

Approximate permutation tests and induced order statistics in the regression discontinuity design

This paper proposes an asymptotically valid permutation test for a testable implication of the identi? cation assumption in the regression discontinuity design (RDD). Here, by testable implication, we mean the requirement that the distribution of observed baseline covariates should not change discontinuously at the threshold of the so-called running variable. This contrasts to the common practice of testing the weaker implication of continuity of the means of the covariates at the threshold. When testing our null hypothesis using observations that are “close” to the threshold, the standard requirement for the ? nite sample validity of a permutation does not necessarily hold. We therefore propose an asymptotic framework where there is a ? xed number of closest observations to the threshold with the sample size going to in? nity, and propose a permutation test based on the so-called induced order statistics that controls the limiting rejection probability under the null hypothesis. In a simulation study, we ? nd that the new test controls size remarkably well in most designs. Finally, we use our test to evaluate the validity of the design in Lee (2008), a well-known application of the RDD to study incumbency advantage.
The atmosphere and ionosphere of Io

A variety of models for Io's atmosphere, ionosphere, surface, and environment are developed and discussed in the context of recent observational data. The sodium emission detected by Brown appears to require a collisional excitation process in Io's atmosphere, and the extended sodium emission measured by Trafton et al. may require scattering of the planetary radiation by an extended sodium cloud. The sodium is presumably present initially in bound form on Io's surface and may be released by the sputtering mechanism suggested by Matson et al. The ionosphere detected by the radio occultation experiment on Pioneer 10 could be attributed to photoionization of atmospheric sodium if Io's atmosphere could sustain significant vertical motions, of order 1 s^(-1) directed up during the day, down at night. Vertical motions of this magnitude could be driven by condensation of atmospheric NH_3. The total density of gas at Io's surface appears to lie in the range 10^(10)-10^(12) molecules cm^(-3). Corpuscular ionization could play an additional role for the Ionosphere. In this case the satellite should exhibit an exceedingly bright, ~ 10 kR, airglow at Lɑ. The incomplete hydrogen torus observed by Judge and Carlson in the vicinity of Io requires a large supply of hydrogen from the satellite's atmosphere. The escape flux should be of order 10^(11) cm^(-2) s^(-1) and could be maintained by photolysis of atmospheric NH_3. The observed geometry of the hydrogen torus appears to require a surprisingly short lifetime, ~ 10^5 s, for neutral hydrogen near Io's orbit, and may indicate the presence of a large flux, ~ 10^9 cm ^(-2) s^(-1), of low-energy protons in Jupiter's magnetosphere. Implications of the hydrogen torus for the energy and mass balance of Jupiter's magnetosphere are discussed briefly, and observational programs are identified which might illuminate present uncertainties in our understanding of Io.
A simplified yet effective fuzzy logic controller for chemical ship tanker

This paper proposes a simplified yet effective control scheme to design a fuzzy logic controller (FLC) for the ship tanker. The proposed method exploits the feature of signed distance method for reducing the conventional two-input FLC (CFLC) into a piecewise linear single input FLC (PWL-FLC). It has been shown that the proposed FLC has a similar structure to the CFLC, exhibiting analogous control performance. However, the main features of the proposed method are the absence of fuzzification, rule inference and defuzzification processes that are essential for CFLC implementation. The proposed PWL-FLC could be easily programmed into a low cost microcontroller using just a look-up table. To authenticate its effectiveness, the control algorithm has been implemented using the marine system simulator in Matlab/Simulink ® platform. The result signifies that both the PWL-FLC and CFLC results in identical functioning performance; however, the former requires least possible tuning effort and its execution time is in the orders of three magnitudes less than its conventional counterpart.
Molecular Cloning of a Potential Verticillium dahliae Resistance Gene SlVe1 with Multi-site Polyadenylation from Solanum licopersicoides

Caused by Verticillium spp. pathogens, verticillium wilt is a common detrimental disease damaging yield production of many important crops. Isolation of verticillium wilt resistance genes and their transgenic application is a fundamental way to control this disease. Here we report the cloning and sequence characterization of a potential Verticillium dahliae Kleb. resistance gene (Ve) from Solanum lycopersicoides Dun. (designated as SlVe1). The nucleotide sequence of SlVe1 is 3400 bp with an ORF of 3156 bp encoding a protein precursor of 1051 amino acids (aa). Unlike tomato Ve1, SlVe1 had a short leader sequence of 22 bp. Multiple polyadenylation sites were detected, which may result from alternative cleavages directed by the common polyadenylation signal AATAAA, and nucleotide sequences of the cleavage sites for polyadenylation conform to PyPyA. Sharing high homologies to tomato verticillium wilt disease resistance genes Ve1 and Ve2, SlVe1 encoded a cell-surface glycoprotein with receptor-mediated endocytosis-like signal. The leucine rich (16.51%) putative SlVe1 protein had a calculated molecular weight of 116.97 kDa with an isoelectric point of 5.22. It possessed a hydrophobic N-terminal signal peptide of 23 aa and 28 predicted significant leucine-rich repeats (LRRs) containing 29 potential N-glycosylation sites (18 being significant). A membrane-associated hydrophobic domain resided within the C-terminal, flanked by a neutral/acidic aa rich domain and a neutral/basic aa rich domain. Forty-four predicted phosphorylation sites (28 for S, 5 for T and 11 for Y) distributed in SlVe1, and an endocytosis signal EKWLLW resided in the neutral/basic aa rich C-terminal domain. As compared with Ve1, several clues of variations have been detected in SlVe1 and their possible implications are discussed.
Enhanced Susceptibility to Citrobacter rodentium Infection in MicroRNA-155-Deficient Mice

ABSTRACT MicroRNAs (miRNAs) are small noncoding molecules that control gene expression posttranscriptionally, with microRNA-155 (miR-155) one of the first to be implicated in immune regulation. Here, we show that miR-155-deficient mice are less able to eradicate a mucosal Citrobacter rodentium infection than wild-type C57BL/6 mice. miR-155-deficient mice exhibited prolonged colonization associated with a higher C. rodentium burden in gastrointestinal tissue and spread into systemic tissues. Germinal center formation and humoral immune responses against C. rodentium were severely impaired in infected miR-155-deficient mice. A similarly susceptible phenotype was observed in μMT mice reconstituted with miR-155-deficient B cells, indicating that miR-155 is required intrinsically for mediating protection against this predominantly luminal bacterial pathogen.
Short-term MCI-to-AD prediction using MRI, neuropsychological scores and ensemble tree learning techniques

This paper analyzes the performance of ensemble tree learning techniques for predicting the progression of Alzheimer's disease (AD) in a longitudinal dataset of 128 mild-cognitive impairment (MCI) subjects from the Alzheimer's disease Neuroimage Initiative (ADNI). The system is evaluated by means of tissue-segmented T1 magnetic resonance images (MRI) as well as Mini Mental State Examination (MMSE) and cognitive assessment subscale (ADAS-Cog) scores collected every 6 months during a three-year follow-up. The ensembles are trained by means of boosting and bagging while their performance is compared in terms of the classification error and the received operating characteristics curve (ROC) using cross validation.
Exploring feature sets for Turkish word sense disambiguation

This paper presents an exploration and evaluation of a diverse set of features that influence word-sense disambiguation (WSD) performance. WSD has the potential to improve many natural language processing (NLP) tasks as being one of the most crucial steps in the area. It is known that exploiting effective features and removing redundant ones help improving the results. There are two groups of feature sets to disambiguate senses and select the most appropriate ones among a set of candidates: collocational and bag-of-words (BoW) features. We introduce the effects of using these two feature sets on the Turkish Lexical Sample Dataset (TLSD), which comprises the most ambiguous verb and noun samples. In addition to our results, joint setting of feature groups has been applied to measure additional improvement in the results. Our results suggest that joint setting of features improves accuracy up to 7%. The effective window size of the ambiguous words has been determined for noun and verb sets. Additionally, the suggested feature set has been investigated on a different corpus that had been used in the previous studies on Turkish WSD. The results of the experiments to investigate diverse morphological groups show that word root and the case marker are significant features to disambiguate senses.
Prehospital systolic blood pressure thresholds: a community-based outcomes study.

OBJECTIVES Emergency medical services (EMS) personnel commonly use systolic blood pressure (sBP) to triage and treat acutely ill patients. The definition of prehospital hypotension and its associated outcomes are poorly defined. The authors sought to determine the discrimination of prehospital sBP thresholds for 30-day mortality and to compare patient classification by best-performing thresholds to traditional cutoffs. METHODS In a community-based cohort of adult, nontrauma, noncardiac arrest patients transported by EMS between 2002 and 2006, entries to state hospital discharge data and death certificates were linked. Prehospital sBP thresholds between 40 and 140 mm Hg in derivation (n = 132,624) and validation (n = 22,020) cohorts and their discrimination for 30-day mortality, were examined. Cutoffs were evaluated using the 0/1 distance, Youden index, and adjusted Z-statistics from multivariable logistic regression models. RESULTS In the derivation cohort, 1,594 (1.2%) died within 24 hours, 7,404 (6%) were critically ill during hospitalization, and 6,888 (5%) died within 30 days. The area under the receiver operating characteristic (ROC) curve for sBP was 0.60 (95% confidence interval [CI] = 0.59, 0.61) for 30-day mortality and 0.64 (95% CI = 0.62 0.66) for 24-hour mortality. The 0/1 distance, Youden index, and adjusted Z-statistics found best-performing sBP thresholds between 110 and 120 mm Hg. When compared to an sBP ≤ 90 mm Hg, a cutoff of 110 mm Hg would identify 17% (n = 137) more deaths at 30 days, while overtriaging four times as many survivors. CONCLUSIONS Prehospital sBP is a modest discriminator of clinical outcomes, yet no threshold avoids substantial misclassification of 30-day mortality among noninjured patients.
The electrocardiogram (ECG) of the baboon (Papio spp.)

6-lead (3 standard, 3 augmented) electrocardiograms were recorded from 150 captured African baboons being used as undosed controls in toxicity studies. The animals, of 14 months to 2 years of age, were unanaesthetised and restrained supine. Analysis of lead II revealed a heart rate of 230±46 beats/min, P-R interval of 0.07±0.02 s, QRS 0.03±0.02 s, Q-T 0.16±0.03 s, and component wave-form amplitudes P (l.6±0.065 mm), Q (0-0.63 mm), R (0-10.44 mm), S (0-5.44 mm), T (0-3.54 mm). The QRS axis was 48±85°. Deep Q waves were rarely seen preceding an R wave. There: was a conspicuous absence of T wave discordancy in direct contrast to the findings of other workers using anaesthetised animals. No sex differences were seen in any parameter.
STIS Model Based Charge Transfer Inefficiency Correction Example Science Case 1 : Proper Motions of Dwarf Galaxies

The STE-CF Calibration Enhancement effort for the Space Telescope Imaging Spectrograph (STIS) aims to improve data calibration via the application of physical modelling techniques. As part of this effort we have developed a model of the STIS CCD readout process that is able to correct STIS data for charge transfer inefficiency (CTI). The model itself is described in some detail in earlier ISRs. Here we give an example of a science case utilizing STIS data, which would be enhanced by this CTI correction: the measurement of the proper motion of Galactic dwarf spheroidal galaxies undertaken by Piatek et al. Without reproducing the entire detailed and thorough analysis involved in the published science case, we demonstrate that apparent centroid shifts introduced by CTI can be as much as ~25mas/century, which is of the order of the proper motion measured by the authors. Moreover the apparent shifts are a function of epoch and position on the CCD detector as well as being aligned within a given dataset. It is unlikely that the proper motion measured by Piatek et al is solely a manifestation of CTI, indeed over the various datasets which they used the CTI induced shifts may, to some extent, cancel out, particularly in cases where the QSO is close to the centre of the chip. However, the true influence of CTI in Piatek et al’s data can only be ascertained by applying their analysis to the CTI corrected datasets, now available for STIS using our CTI pre-processor.

Chandra and ALMA observations of the nuclear activity in two strongly lensed star forming galaxies

Nuclear activity and star formation play relevant roles in the early stages of galaxy formation. We aim at identifying them in high redshift galaxies by exploiting high-resolution and sensitivity X-ray and mm data to confirm their presence and relative role in contributing to the galaxy SEDs and energy budget. We present the data, model and analysis in the X-ray and mm bands for two strongly lensed galaxies, SDP.9 and SDP.11, selected in the Herschel-ATLAS catalogues as having an excess emission in the mid-IR regime at z>1.5, suggesting nuclear activity in the early stages of galaxy formation. We observed both of them in X-ray with Chandra and analyzed the high-resolution mm data available in the ALMA Science Archive for SDP9, and, by combining the information available, we reconstructed the source morphology. Both the targets were detected in the X-ray, strongly indicating the presence of highly obscured nuclear activity. High resolution ALMA observations for SDP9 in continuum and CO(6-5) spectral line allowed us to estimate the lensed galaxy redshift to a better accuracy than pre-ALMA estimates and to model the emission of the optical, mm, and X-ray band emission for this galaxy. We demonstrated that the X-ray emission is generated in the nuclear environment and it strongly support the presence of nuclear activity in this object. Hence, we identified weak nuclear activity associated with high-z galaxies with large star formation rates, useful to extend the investigation of the relationship between star formation and nuclear activity to two intrinsically less luminous, high-z star forming galaxies than was possible so far. Given our results only for two objects, they solely cannot constrain the evolutionary models, but provide us with interesting hints and set an observational path towards addressing the role of star formation and nuclear activity in forming galaxies.
The EPICure Study: Outcomes to Discharge From Hospital for Infants Born at the Threshold of Viability

Objective. To evaluate the outcome for all infants born before 26 weeks of gestation in the United Kingdom and the Republic of Ireland. This report is of survival and complications up until discharge from hospital. Methodology. A prospective observational study of all births between March 1, 1995 and December 31, 1995 from 20 to 25 weeks of gestation. Results. A total of 4004 births were recorded, and 811 infants were admitted for intensive care. Overall survival was 39% (n = 314). Male sex, no reported chorioamnionitis, no antenatal steroids, persistent bradycardia at 5 minutes, hypothermia, and high Clinical Risk Index for Babies (CRIB) score were all independently associated with death. Of the survivors, 17% had parenchymal cysts and/or hydrocephalus, 14% received treatment for retinopathy of prematurity (ROP), and 51% needed supplementary oxygen at the expected date of delivery. Failure to administer antenatal steroids and postnatal transfer for intensive care within 24 hours of birth were predictive of major scan abnormality; lower gestation was predictive of severe ROP, while being born to a black mother was protective. Being of lower gestation, male sex, tocolysis, low maternal age, neonatal hypothermia, a high CRIB score, and surfactant therapy were all predictive of oxygen dependency. Intensive care was provided in 137 units, only 8 of which had >5 survivors. There was no difference in survival between institutions when divided into quintiles based on their numbers of extremely preterm births or admissions. Conclusions. This study provides outcome data for this geographically defined cohort; survival and neonatal morbidity are consistent with previous data from the United Kingdom and facilitate comparison with other geographically based data.
