Cepheid Calibrations from the Hubble Space Telescope of the Luminosity of Two Recent Type Ia Supernovae and a Redetermination of the Hubble Constant

We report observations of two nearby Type Ia supernovae (SNe Ia) for which observations of Cepheid variables in the host galaxies have been obtained with the Hubble Space Telescope: SN 1994ae in NGC 3370 and SN 1998aq in NGC 3982. For NCG 3370, we used the Advanced Camera for Surveys to observe 64 Cepheids that yield a distance of 29 Mpc, the farthest direct measurement of Cepheids. We have measured emission lines from H II regions in both host galaxies that provide metallicity-dependent corrections to their period-luminosity relations. These two SNe Ia double the sample of "ideal" luminosity calibrators: objects with well-observed and well-calibrated light curves of typical shape and with low reddening. By comparing them to all similarly well-measured SNe Ia in the Hubble flow, we find that H0 = 73 ± 4 (statistical) ± 5 (systematic) km s-1 Mpc-1. A detailed analysis demonstrates that most of the past disagreement over the value of H0 as determined from SNe Ia is abated by the replacement of past, problematic data by more accurate and precise, modern data.

Conversion from cyclosporin (Neoral®) to tacrolimus (Prograf®) in renal allograft recipients with chronic graft nephropathy: results of an observational study

Abstract To evaluate the role of tacrolimus in the treatment of Chronic Graft Nephropathy (CGN), a pilot cross-sectional study was performed on 14 patients with deteriorating renal function and biopsy-proven CGN. Maintenance therapy was switched from cyclosporin to tacrolimus, and results of conversion on allograft function were assessed by estimated glomerular filtration rate (GFR) and clinical outcome. Minimum follow-up was 15 months. Two distinctive response patterns emerged: (i) continuing deterioration of renal function with no apparent benefit over the projected trend of GFR (nine patients), and (ii) unequivocal change in the GFR trend line equation with reduced rate of deterioration in one patient and sustained improvement of GFR in four patients (reversal of downward trend). Five out of 14 patients (36 %) benefited from replacing Neoral with Prograf. All five patients exceeded their estimated time of return to dialysis by a median of 41 weeks (range: 29–52) and their grafts continue to function.
Robust-formation control of multi-Autonomous Underwater Vehicles based on consensus algorithm

This paper discusses a robust formation control for multi-Autonomous Underwater Vehicles (AUVs). The AUVs are disturbed by exogenous perturbation during the mission, thus, the Robust Integral Sign of Error (RISE) is adopted. For a formation control, a leader-follower structure based on consensus algorithm is adopted and the use of graph theorem named connected graph is useful to exchange the required information. An AUV called leader is determined to bring a group of information, while the others called followers, receive the information from a leader. Lyapunov analysis proves the stability as well as the error convergence of proposed controller, whilst some simulations are performed to compare between the proposed controller, RISE with consensus, and the existing robust controller, Sliding Mode Controller (SMC) which is combined with consensus algorithm. As a result, the proposed controller works better and produces smaller error.
HIV and pregnancy--is vaginal delivery a safe and viable option?

HIV in children is predominantly acquired vertically. Without intervention, mother to child transmission (MTCT) has varied from 20%-40%(1). Vertical transmission of HIV can occur in utero through placental transmission, intrapartum through contact with infected birth canal secretions or postpartum through breast feeding. It is estimated that of the 30% of babies who get infected vertically, 2% get infected in early gestation, 3% get infected in late gestation, 15% get infected intrapartum and 10% get infected via breast feeding(2). HIV transmission from infected mother to child is mainly prevented by antiretroviral drug (ARV) prophylaxis to mother and baby, replacement feeding and elective cesarean section. ARV prophylaxis acts by reducing viral load in the mother and as post-exposure prophylaxis to the baby. Cesarean section decreases risk of intrapartum transmission of HIV by decreasing transplacental hemorrhage during labour and reducing the length of exposure of baby to vaginocervical secretions. Cesarean section decreases transmission by approximately 50 percent as compared to other modes of delivery(3). MTCT rates of less than 2% have been reported from countries where ARV prophylaxis, cesarean section and avoidance of breast feeding is practiced. However, in a setting where ARV prophylaxis as well as replacement feeding is provided, is there really a necessity of elective cesarean section delivery?
Internet browsing through RFID-powered gadgets

The vision of the Internet of Things is challenging researchers from different fields with the common goal of designing innovative Internet-connected experiences or augmenting existing objects’ capabilities with Internet-related features. During these first stages, researchers must explore new ways and concepts, and share the results with the scientific community. In this paper, we present our work on creating RFID-based smart gadgets in order to take Internet experience to the next level, merging the on-line and the tangible worlds into a single continuous space.
USING REDUCE FOR REPLICA

The REDUCE package REPPACK for performing replica calculations in the context of neural networks is presented. REPPACK provides the user with several functions needed to calculate partition functions and saddle point equations interactively. The application of REPPACK is demonstrated for the toy example of nitely many patterns (p=N ! 0) for the Hoppeld model. The Gardner calculation with REPPACK is brieey outlined.
Assessment of Chest High-Field Magnetic Resonance Imaging in Children and Young Adults With Noncystic Fibrosis Chronic Lung Disease: Comparison to High-Resolution Computed Tomography and Correlation With Pulmonary Function

Objectives:Magnetic resonance imaging (MRI) has been proposed as a radiation-free alternative to high resolution computed tomography (HRCT) for the assessment and follow-up of chest disorders. Thus far, no study has compared the efficacy of high-field MRI and HRCT in children and adults with noncystic fibrosis (CF) chronic lung disease. The aims of our study were: (1) to assess whether chest high-field MRI is as effective as chest HRCT in identifying pulmonary abnormalities; and (2) to investigate the relationships between the severity and extent of lung disease, and functional data in patients with non-CF chronic lung disease. Materials and Methods:Forty-one subjects (median age, 13.8 years; range, 5.9–29.3 years; 30 children/11 adults) with primary ciliary dyskinesia (n = 14), primary immunodeficiency (n = 14), or recurrent pneumonia (n = 13) underwent pulmonary function tests, chest HRCT (120 kV, dose-modulated mAs) and high-field 3.0-T MRI (HASTE; transversal orientation; repetition time/echo time/flip angle/acquisition time, infinite/92 milliseconds/150°/approximately 90 seconds). HRCT and MRI images were scored in consensus by 2 raters using a modified version of the Helbich scoring system. The maximal score was 25. Results:HRCT and high-field MRI total scores were 11 (range: 1–20) and 11 (range: 1–17), respectively. There was good agreement between the 2 techniques for all scores (r > 0.8). HRCT and MRI total scores, and extent of bronchiectasis scores were significantly related to pulmonary function tests (r = −0.4, P < 0.05). The MRI mucous plugging score was significantly related to pulmonary function tests (r = −0.4, P < 0.05). Conclusions:Chest high-field 3.0-T MRI appears to be as effective as HRCT in assessing the extent and severity of lung abnormalities in non-CF chronic lung diseases, and might be a reliable radiation-free option to HRCT.
On the causality problem in time-domain blind source separation and deconvolution algorithms

Using a recently presented generic framework for multichannel blind signal processing for convolutive mixtures, we investigate the problem of incorporating acausal delays which are necessary with certain geometric constellations. Starting from a generic update equation which is applicable to blind source separation (BSS), multichannel blind deconvolution (MCBD), and multichannel blind partial deconvolution (MCBPD) for dereverberation of speech signals, two formulations of the natural gradient are derived. It is shown that one expression is applicable to mere causal filters whereas the other also allows an implementation of noncausal filters. Moreover, proper initialization methods for both cases are given. For the implementation of these algorithms, cross-relation estimation techniques, known from linear prediction, are discussed. Based on these results, relationships between traditional MCBD algorithms can be established. Experimental results of different acoustic scenarios show the applicability of the presented algorithms.
Hypoxia and Ionizing Radiation: Changes in Adhesive Properties and Cell Adhesion Molecule Expression in MG-63 Three-Dimensional Tumor Spheroids

The effects of chemically induced hypoxia and ionizing radiation on the adhesive properties of MG-63 human osteosarcoma three-dimensional spheroids were investigated. Hypoxia was induced by addition of CoCl2 to small, nonhypoxic spheroids and verified by HIF-1α expression. In addition, the possible role of important cell adhesion molecules involved in tumor dissemination in inducing adhesive changes were also studied. In particular, two key integrins (i.e., the alpha chain of the fibronectin receptor, α5, and the alpha chain of the collagen receptor, α2), an important member of the immunoglobulin superfamily (CD54 or ICAM-1) and the strategic molecule CD44 (H-CAM, the principal receptor for hyaluronan) were examined. Because of the important role of fibronectin in adhesive processes, variations in this extracellular matrix component were also examined. The results seem to indicate that CoCl2-induced hypoxia greatly increases adhesion of MG-63 spheroids to both tissue culture plates and plates coated with fibronectin or collagen when compared to controls, while ionizing radiation induces a great decrease in this attachment. Furthermore, chemically induced hypoxia also partially inhibits the effects of ionizing radiation. The data also show that these adhesive changes are accompanied by concomitant variations in the expression of α5 and α2 integrins, CD44, and CD54 and fibronectin.
A Capability – Driven modelling approach applied in smart transportation & management systems for large scale events

Economic growth in Europe has been, strongly associated with urbanization, overwhelming cities with vehicles. This renders mobility inside cities problematic, since it is often associated with large waste of time in traffic congestions, environmental pollution and accidents. Cities struggle to invent and deploy “smart” solutions in the domain of urban mobility, so as to offer innovative services to citizens and visitors and improve the overall quality of life. At the same time, organisation of large-scale events impose even more challenges and difficulties in the provision of such services. In this context, the paper discusses on the basic challenges that cities face especially in cases of large scale events, and proposes a capability – driven enterprise modelling approach towards enabling Smart Objects for Smart City Operations (SCO). It presents specific examples of deploying this approach in smart traffic management and smart spectators’ management in large scale events. Moreover, a process towards linking capability models to simulation ones is presented, trying to set the basis for effective SCO based on Smart Objects deployment.
Effect of Auditory Constraints on Motor Performance Depends on Stage of Recovery Post-Stroke

In order to develop evidence-based rehabilitation protocols post-stroke, one must first reconcile the vast heterogeneity in the post-stroke population and develop protocols to facilitate motor learning in the various subgroups. The main purpose of this study is to show that auditory constraints interact with the stage of recovery post-stroke to influence motor learning. We characterized the stages of upper limb recovery using task-based kinematic measures in 20 subjects with chronic hemiparesis. We used a bimanual wrist extension task, performed with a custom-made wrist trainer, to facilitate learning of wrist extension in the paretic hand under four auditory conditions: (1) without auditory cueing; (2) to non-musical happy sounds; (3) to self-selected music; and (4) to a metronome beat set at a comfortable tempo. Two bimanual trials (15 s each) were followed by one unimanual trial with the paretic hand over six cycles under each condition. Clinical metrics, wrist and arm kinematics, and electromyographic activity were recorded. Hierarchical cluster analysis with the Mahalanobis metric based on baseline speed and extent of wrist movement stratified subjects into three distinct groups, which reflected their stage of recovery: spastic paresis, spastic co-contraction, and minimal paresis. In spastic paresis, the metronome beat increased wrist extension, but also increased muscle co-activation across the wrist. In contrast, in spastic co-contraction, no auditory stimulation increased wrist extension and reduced co-activation. In minimal paresis, wrist extension did not improve under any condition. The results suggest that auditory task constraints interact with stage of recovery during motor learning after stroke, perhaps due to recruitment of distinct neural substrates over the course of recovery. The findings advance our understanding of the mechanisms of progression of motor recovery and lay the foundation for personalized treatment algorithms post-stroke.
Altimetric precision of Delay Doppler Altimetry over the ocean with numerical simulations from the Cryosat mission performance simulator

The launch of the ESA Cryosat-2 mission in March 2009 will be the first example of a Delay Doppler altimeter flown in space. With a ten-fold increase in pulse repetition frequency, Delay-Doppler altimeters, also known as SAR altimeters, will be characterised by pulse-to-pulse coherence to enable Doppler cell selection within the radar antenna footprint. The Delay Doppler Altimeter (DDA) concept was first proposed by Raney (1998) and promises improved altimetric precision and higher along-track resolution compared to conventional pulse-limited altimeters.
STEREOTYPING OF BEING MUSLIM IN AMERICA REFLECTED IN JOHAR‟S MY NAME IS KHAN (2010): A SOCIOLOGICAL APPROACH

This research paper elaborates the stereotyping of being Muslim in America that is reflected in My Name is Khan movie, which are analyzed through sociological approach. The objectives of the research are to analyze the movie based on its structural elements and to analyze the movie by using Sociological approach. This research paper belongs to qualitative research. The sources of the data come from both primary data source, which is My Name is Khan movie and secondary data sources, which are the author’s biography, essay, comment, historical information and other relevant information. The method to analyze the data is descriptive analysis. Having analyzing the movie, the writer comes to the conclusion as follows. First, based on the structural analysis of each element, it shows that all of the characters supported by the setting, plot and completed by perfect mise-en-scene, cinematography, sound and editing, finally form a good movie. Secondly, based on the sociological analysis, there is closed relation between the production of this movie and the social reality underlying it. The major factor that contributes to the production of this movie is the stereotyping of being Muslim in America after WTC attack. This movie also stresses on the sacrifice of a Muslim in America to prove that he is not a terrorist.
Weak Consistency in Distributed Data Warehouses

We propose and analyze a novel multiple-view model of a distributed data warehouse. Views are represented in a hierarchical fashion, incorporating data from base sources as well as possibly other views. Current approaches to maintain consistency in such a model require that data stored in a view derived from base data via diierent paths be from the same state of the base relation. This type of consistency criterion is too restrictive for some applications. Hence, we propose relaxing the synchronization constraints at the view level and develop a model that allows views to set their own constraints by enforcing individual conditions for all pairs of paths. We deene a correctness criteria for updates in this particular model, and analyze the new requirements necessary for maintaining the consistency of data. Finally, we propose an algorithm to ensure that views are updated consistently.
Binocular interactions in accommodation control: effects of anisometropic stimuli

In binocular viewing of real targets, the accommodative demand in the two eyes is not in general identical, yet the accommodation response in the two eyes is equal. In order to investigate how the accommodative signals from the two eyes are combined, this study has examined the effects of several forms of dynamic anisometropic stimulation on the accommodation response in both man and the rhesus monkey (Macaca mulatta). All experiments were performed in a computer-controlled haploscopic apparatus to allow independent control of the accommodative stimuli to the two eyes and of the vergence stimulus. The vergence stimulus was held constant while the accommodation demand was modulated independently in each eye. Accommodation was monitored continuously with a dynamic infrared optometer. Four anisometropic conditions were used. In two of these conditions, accommodation demand was varied sinusoidally with time in both eyes, but with phases differing by 90 degrees or 180 degrees between the two eyes. In the two remaining conditions, accommodation demand in one eye varied sinusoidally, while the accommodation demand was constant in the other. In all cases, the form of the target pattern was identified in the two eyes. The accommodation responses observed with these stimulus conditions were similar in both man and the monkey. When presented with conflicting stimuli in the two eyes, the accommodation response appeared to be best described as a compromise between the inputs to the two eyes; there were no indications of a purely random alternation of eye dominance of the form seen in binocular contour rivalry. When the accommodation demand was modulated in only one eye, there was a modulated accommodation response of similar phase to the control condition (i.e., both eyes modulated in phase) but with a much smaller gain (mean, 39% of control gain). When the accommodation demand was modulated in both eyes with a phase difference of 180 degrees, no significant modulation was observed in the accommodation response at the stimulation frequency. When the interocular phase difference was 90 degrees, a modulated response was observed that showed a mean phase lag 41 degrees more than that observed in the control condition (both eyes modulated in phase) and an appreciably smaller gain (mean, 55% of control gain). The extent to which the results can be described by a linear vector average of the uniocular inputs is considered.
Localization of paternal H-2K antigens on murine trophoblast cells in vivo

We have previously shown the presence of H-2K and D antigens of both parental haplotypes on dispersed murine trophoblast cells. The question still remained whether such antigens are sequestered away from the sinusoidal face of these cells making them inert as allografts. The in vivo expression of H-2 antigens on these cells was therefore examined radioautographically after perfusion of 125I-labeled monoclonal and anti-H-2Kk (anti-paternal) antibody directly into individual placental branches of the uterine artery suppling 15-d-old (C57BL/6J female) X CBA/J male) placentae. Syngeneic C57BL/6J placentae served as negative controls. A radioautographic examination of 0.5-micrometer-thick sections revealed specific labeling of labyrinthine trophoblasts lining the sinusoids of allogeneic placentae. Most of this labeling was localized to the sinusoidal face of the cells as opposed to a weak labeling of the intracellular aspect. Spongiotrophoblasts and trophoblast giant cells did not label, but specific labeling of fetal capillary endothelium and some macrophages was also noted.
Affordances of Equality: Ranciere, Emerging Media, and the New Amateur

This article extends a recent educational engagement with the work of Jacques Rancière by linking his meditations on 19th-century worker emancipation to present cultural contexts and media forms. Taking Nick Prior’s (2010) notion of the “new amateur” as point of departure, I argue that new media and attendant production contexts offer an unprecedented occasion for rethinking the educational experiments of Joseph Jacotot (the subject of Rancière’s The Ignorant Schoolmaster, 1991). By bringing Jacotot’s “method of equality” into relation with present forms of cultural production, I elaborate a notion of affordances of equality that updates Jacotot’s practice of “experimenting with the gap between accreditation and act” (Rancière, 1991, p. 15) —a method that invited learners to improvise in the gap between an expert role and a talent imitable by anyone at all. In conclusion, I ask what educational theory might learn from the new amateur, from the emerging media these amateurs are engaging, and from the production literacies they enact.
Comparative clinical study of protein SAP (amyloid P component) and C-reactive protein in serum.

The serum concentration of protein SAP (amyloid P component) has been measured for the first time in a substantial series of normal individuals and patients with various diseases, and the results contrasted with the levels of the related protein C-reactive protein (CRP). The mean +/- s.d. concentration of protein SAP was 43 +/- 14 microgram/ml in seventy-six normal men, 33 +/- 10 microgram/ml in eighty-six normal women and 4 +/- 2 microgram/ml in thirty-six normal cord sera. Unlike CRP, whick is a major acute phase reactant, protein SAP was only slightly elevated in inflammatory and neoplastic diseases in which CRP was greatly increased. The level of protein SAP was significantly depressed in patients with hepatic disease, suggesting that its measurement might be of value in their management.
