Extrapolation of data external to the measurement region: In the bi-polar scanning

Among the near field-far field (NF-FF) transformation techniques, that employing the bi-polar scanning, proposed by Rahmat-Samii et al. in [1], is particularly attractive due to its peculiar characteristics. In such a scanning, the antenna under test (AUT) rotates axially, whereas the probe is attached to the end of an arm which rotates around an axis parallel to the AUT one. This allows one to collect the NF data on a grid of concentric rings and radial arcs (Fig. 1). The bi-polar scanning maintains all the advantages of the plane-polar one while providing a simple and cost-effective measurement system. In fact, since the arm is fixed at one point and the probe is attached at its end, the bending is constant and this allows to hold the planarity. Moreover, rotational movements are preferable to the linear ones, since rotating tables are more accurate than linear positioners. An efficient probe compensated NF-FF transformation using a bi-polar scanning has been recently developed by the authors in [2] by considering the AUT as enclosed in an oblate ellipsoid, a source modelling particularly suitable to deal with quasi-planar antennas. Such a technique is based on the theoretical results [3] concerning the nonredundant sampling representations of the electromagnetic (EM) fields for antennas enclosed in arbitrary convex domains with rotational symmetry and observed on surfaces having the same symmetry. It allows one to lower the number of needed NF data in a significant way with respect to the classical bi-polar scanning without losing the efficiency. An optimal sampling interpolation (OSI) algorithm has been applied to recover the plane-rectangular data from the bi-polar ones, thus enabling the use of the FFT in the NF-FF transformation.

SmartLAK: A big data architecture for supporting learning analytics services

In this paper, we present a big data software architecture that uses an ontology, based on the Experience API specification, to semantically represent the data streams generated by the learners when they undertake the learning activities of a course, e.g., in a course. These data are stored in a RDF database to provide a high performance access so learning analytics services can process the large amount of data generated in a virtual learning environment. These services provide valuable information to teachers and instructors such as predict the learner's performance, discover the real learning paths, extract the learner's behavior patterns and so on. The proposed architecture has been validated in the Educational Technology undergraduate course of the Degree in Pedagogy at the Faculty of Education of the University of Santiago de Compostela.
The Unlicensed Lives of Antidepressants in India: Generic Drugs, Unqualified Practitioners, and Floating Prescriptions

Antidepressant uses have been rising rapidly over the past decades. Two main theories have been advanced to explain this. One claims that socio-economic change causes a global rise of depressive illness. The other holds that European and North American corporations are aggressively marketing antidepressants to expand their global reach. Both theories assume that multinational capitalism drives rising depression rates. Based on ethnographic data from India, this article shows that antidepressants are increasingly used in this country as well, but for reasons than have been little explored yet. Taking fluoxetine (Prozac) as the main example, it is argued that the spread of antidepressants in India is `unlicensed' by Euro-American corporations in at least three ways: (i) drug marketing is driven by Indian generic producers; (ii) fluoxetine is given by practitioners who have no license to do so; and (iii) knowledge of fluoxetine is spread through unlicensed `floating' prescriptions that patients take from one prescriber to another.
Application of UPQC to protect a sensitive load on a polluted distribution network

The application of active power conditioners to tackle power quality problems has become a matured subject. This paper is based on a unified approach for load and source compensation using unified power quality conditioner (UPQC). Performance of this UPQC has been evaluated with a typical industrial load with realistic parameters supplied by a polluted distribution network. The system performance for current harmonics, voltage harmonics, voltage sag and voltage swell has been evaluated. The MATLAB / Simulink based simulations are provided which support the functionality of the UPQC
Effects of the chaotic noise on the performance of a neural network model for optimization problems.

We studied effects of chaos added to the dynamics of a neural network model. By numerical simulations, we found the neural network with forcing by chaotic noise operated very efficiently to solve an optimization problem. We also showed that short time correlation of chaos was relevant to the dynamics of the network and it could work effectively for global minima search.
ADP-ribosylation of the G Protein Rho Inhibits Integrin Regulation of Tumor Cell Growth (*)

Using a gastric derived tumor line, we investigated the involvement of β1 integrin and Rho in cell growth regulation in response to collagen. The addition of C3 exoenzyme from Clostridium botulinum to specifically ribosylate and inhibit the function of the rho gene products inhibited cellular proliferation in a dose-dependent fashion. C3 exoenzyme exhibited broad cytostatic activity toward a number of tumor lines and induced G/G accumulation, cyclin A inhibition, and pronounced alterations in cell morphology. Integrin-mediated adhesion to collagen led to the expression of the cyclin A gene whose expression could be blocked using anti-β1 integrin monoclonal antibodies. Phospholipid levels were induced upon β1 integrin-mediated adhesion to collagen, and the phospholipid induction was inhibited by either antibodies to β1 integrin or pretreatment of cells with C3 exoenzyme. Significant reduction in phospholipid levels correlated with proliferation for a panel of tumor lines deprived of adhesion to substrate. These results implicate a novel role for integrins and Rho in the regulation of tumor growth in response to matrix.
Discovery of a strong magnetic field in the rapidly rotating B2Vn star HR 7355

Abstract We report on the detection of a strong, organized magnetic field in the helium-variable early B-type star HR 7355 using spectropolarimetric data obtained with ESPaDOnS on CFHT by the MiMeS large program. We also present results from new V-band differential photometry obtained with the CTIO 0.9m telescope. We investigate the longitudinal field, using a technique called Least-Squares Deconvolution (LSD), and the rotational period of HR 7355. These new observations strongly support the proposal that HR 7355 harbors a structured magnetosphere similar to that in the prototypical helium-strong star, σ Ori E.
Band Selection-Based Dimensionality Reduction for Change Detection in Multi-Temporal Hyperspectral Images

This paper proposes to use band selection-based dimensionality reduction (BS-DR) technique in addressing a challenging multi-temporal hyperspectral images change detection (HSI-CD) problem. The aim of this work is to analyze and evaluate in detail the CD performance by selecting the most informative band subset from the original high-dimensional data space. In particular, for cases where ground reference data are available or unavailable, either supervised or unsupervised CD approaches are designed. The following sub-problems in HSI-CD are investigated, including: (1) the estimated number of multi-class changes; (2) the binary CD; (3) the multiple CD; (4) the estimated optimal number of selected bands; and (5) computational efficiency. The main contribution of this paper is to provide for the first time a thorough analysis of the impacts of band selection on the HSI-CD problem, thus to fix the gap in the state-of-the-art techniques either by simply utilizing the full dimensionality of the data or exploring a complex hierarchical change analysis. It is applicable to CD problems in multispectral or PolSAR images when the feature space is expanded for discriminant feature extraction. Two real multi-temporal hyperspectral Hyperion datasets are used to validate the proposed approaches. Quantitative and qualitative experimental results demonstrated that by selecting a subset of the most informative and distinct spectral bands, the proposed approaches offered better CD performance than the state-of-the-art techniques using original full bands, without losing the change representative and discriminable capabilities of a detector.
An Assessment of Surface and Zonal Models of population

A harnessing device formed by a locking head and an attached webbed strap. The head contains oppositely positioned locking tangs in a guide channel that receives the strap after encirclement of items to be harnessed. The tangs engage abutments of the webbed strap for adjustable retention of the harnessed items. The strap is advantageously molded of a stretch reorientable material. Stretching produces a relatively thin and strengthened web which resists penetration by the locking tangs and reduces the possibility of failure by fracture or reverse rotation. The inclusion of the relatively thin web also promotes homogeniety during molding and avoids imperfections that can cause failure in other types of straps.
Effect of Risperidone on Serum Cytokines

A variety of cytokines are dysregulated in schizophrenia, and some anti-psychotic drugs effect cytokines. In order to examine the effect of risperidone on plasma cytokines. we measured the serum level of IL-lb, IL-2, IL-6, IL-12, and INF-g during acute states of illness, and after 4 weeks of treatment with risperidone in 19 schizophrenic patients. The patients' psychopathology was assessed by PANSS. Plasma IL-12 levels increased significantly after 4 weeks of treatment (p =. 002). Plasma IL-b, IL-2, IL-6, and INF-g levels were not significantly different before and after treatment. There were no significant correlations between the changes in cytokine levels and the changes in PANSS scores. Increased IL-12 max contribute to activation of immune responses during treatment with risperidone. IL-12 may play an important role in immune responses related to neuropsychiatry.
Les grammaires attribuées pour la conception et l'assemblage de langages dédiés. (Attribute Grammars for the Modular Design of Domain Specific Languages)

La Programmation Orientee Langage est un paradigme de programmation qui tente, par la technique de meta-programmation, de changer les habitudes des developpeurs de systemes informatiques en leur permettant de "travailler en termes de concepts et notions du probleme a resoudre, au lieu d'etre toujours obliges de traduire leurs idees aux notions qu'un langage generaliste est capable de comprendre" (Ward et Sergey). Le developpement de logiciels passe de ce fait par la conception de langages dedies : on definit un ou plusieurs langages qui capturent les caracteristiques du domaine etudie, puis on ecrit les applications visees en utilisant ces langages. Dans cette these, nous proposons une demarche methodologique de developpement logiciel reposant sur ce concept. Il s'agit de conduire la meme demarche methodologique au niveau des langages que ce qui est classiquement fait au niveau des composants logiciels. En l'occurrence, nous utilisons le formalisme des grammaires attribuees pour tenter de repondre a la question suivante : comment peut-on creer de nouveaux langages par composition de langages reutilisables existants ? Nous tirons profit de leur traduction en algebres de combinateurs fonctionnels pour definir des specifications executables de langages dedies (vus comme composants logiciels), plonges dans le langage fonctionnel pur Haskell. \'{A} partir d'exemples significatifs d'extension et de reutilisation de langages dedies (par stratification de ceux-ci, ou par changement de monade), nous proposons un typage de langages dedies en vue de leur assemblage et leur reutilisation. Pour illustrer cette demarche, nous decrivons un langage dedie (bibliotheque de combinateurs) pour l'edition de documents structures. Un document y est represente par un zipper attribue, une structure arborescente localisable, representant un arbre et son contexte, et caracterisee par une grammaire attribuee. L'edition consiste alors a la modification interactive de cette structure ; ce qui entraine une reevaluation totale ou partielle des attributs. L'edition peut aussi etre realisee a travers une vue abstraite obtenue par projection de la structure concrete. Ce qui pose le probleme de \textit{mise a jour de vue}, un probleme familier de la communaute des bases de donnees, auquel nous donnons une solution grâce a nos combinateurs d'editeurs.
Improved Adenoviral Vector for Vascular Gene Therapy: Beneficial Effects on Vascular Function and Inflammation

Abstract— First-generation, E1-deleted adenoviral vectors (&Dgr;E1-AV) can transduce the vascular endothelium with high efficiency, but their use is limited by the resulting acute endothelial injury and the long-term development of intimal hyperplasia. To reduce the impact of viral proteins on the gene-modified cells, a second-generation adenoviral vector with an additional pair of deletions in the E4 region was developed. To determine whether this &Dgr;E1/&Dgr;E4-AV vector would be useful for vascular gene transfer, we directly compared the efficiency of gene transfer to uninjured rabbit carotid arteries using either an &Dgr;E1/&Dgr;E4-AV or an &Dgr;E1-AV vector encoding &bgr;-galactosidase. Both vectors efficiently transduced vascular endothelium; however, the &Dgr;E1/&Dgr;E4-AV vector gene-modified vessels showed higher &bgr;-galactosidase expression 10 days after gene transfer. Importantly, the &Dgr;E1/&Dgr;E4-AV vector produced substantially less endothelial cell activation, less inflammation, and reduced neointimal hyperplasia compared with the &Dgr;E1-AV vector-treated vessels. The &Dgr;E1-AV vector-transduced vessels also demonstrated significantly impaired endothelium-dependent relaxation whereas the &Dgr;E1/&Dgr;E4-AV vector did not impact vasomotor function, even at doses of virus in 5-fold excess of the amount required for >90% transduction of the endothelium. We conclude that the &Dgr;E1/&Dgr;E4-AV vector is superior to the &Dgr;E1-AV vector for vascular gene therapy because of the prolonged transgene expression, reduced vascular inflammation, reduced intimal hyperplasia, and maintenance of normal vasomotor function.
Clinical and Microbiologic Analysis of the Risk Factors for Mortality in Patients with Heterogeneous Vancomycin-Intermediate Staphylococcus aureus Bacteremia

ABSTRACT The prevalence of the heterogeneous vancomycin-intermediate Staphylococcus aureus (hVISA) phenotype among methicillin-resistant S. aureus (MRSA) blood isolates can reach 38%. hVISA bacteremia is known to be associated with vancomycin treatment failure, including persistent bacteremia. We conducted this study to evaluate risk factors for 12-week mortality in patients with hVISA bacteremia through a detailed clinical and microbiological analysis of a prospective cohort of patients with S. aureus bacteremia. All isolates were collected on the first day of bacteremia and subjected to population analysis profiling for hVISA detection, genotyping, and PCR analysis for 39 virulence factors. Of 382 patient with MRSA bacteremia, 121 (32%) had hVISA bacteremia. Deceased patients were more likely to have hematologic malignancy (P = 0.033), ultimately or rapidly fatal disease (P = 0.007), and a higher Pitt bacteremia score (P = 0.010) than surviving patients. The sequence type 239 (ST239) clonal type and definitive linezolid treatment were associated with a trend toward reduced mortality (P = 0.061 and 0.072, respectively), but a high vancomycin MIC (≥2 mg/liter) was not associated with increased mortality (P = 0.368). In a multivariate analysis, ultimately or rapidly fatal disease (adjusted odds ratio [aOR], 2.80; 95% confidence interval [CI], 1.14 to 6.85) and a high Pitt bacteremia score (aOR, 1.26; 95% CI, 1.07 to 1.48) were independent risk factors for mortality. Hematologic malignancy was associated with a trend toward increased mortality (P = 0.094), and ST239 was associated with a trend toward reduced mortality (P = 0.095). Our study suggests that ST239 hVISA is a possible predictor of survival in hVISA bacteremia.
Correlation between quantal secretion and vesicle loss at the frog neuromuscular junction.

1. We measured the rate of occurrence of miniature endplate potentials (MEPPs) at identified endplates in frog cutaneous pectoris muscles treated with crude black widow spider venom (BWSV) or purified alpha‐latrotoxin (alpha‐LTX) in calcium‐free solutions, and we examined the relationship between the length of the nerve terminal and the total number of quanta secreted, and the relationship between the number of quanta secreted and the number of vesicles remaining at different times. 2. The venom, or toxin, was applied in a modified Ringer solution with tetrodotoxin, 1 mM‐EGTA and no divalent cations, and quantal secretion was started by applying Ca2(+)‐free solutions with Mg2+. This was done to synchronize the quantal discharge at the various junctions in a muscle. Ringer solution was applied after the MEPP rate had declined to low levels, and then the muscle fibre was injected with Lucifer Yellow, the endplate stained for acetylcholinesterase and the length of the nerve terminal and the length of a sarcomere were measured on the fluorescent fibre. 3. The total number of quanta secreted by a terminal was measured under a wide variety of experimental conditions: the weights of the frogs ranged from 13 to 68 g, the temperature from 9 to 28 degrees C, and the concentration of Mg2+ from 2 to 10 mM. In one series of experiments the Mg2+ was withdrawn after 3‐4 min and reapplied 35‐40 min later in order to divide the total output of quanta into two approximately equal bouts of secretion that were well separated in time. 4. The total number of MEPPs recorded at a junction was loosely correlated with the length of its nerve terminal, but it was not affected by the temperature, the concentration of Mg2+ or the division of secretion into well‐separated bouts of quantal release. The average total secretion per unit length was about 3700 quanta/sarcomere or about 1200 quanta/microns. 5. The average time course of quantal secretion per micrometre of terminal was determined at single junctions in muscles held at 22‐23 degrees C or at 9‐10 degrees C. Other muscles were fixed at various times during the course of secretion at each temperature and the number of synaptic vesicles remaining in cross‐sections of the terminals were counted on electron micrographs. The number of vesicles remaining per micrometre of terminal was determined from the number per cross‐section and the section thickness. (ABSTRACT TRUNCATED AT 400 WORDS)
In vitro reconstructed mucosa‐integrating Langerhans' cells

Abstract: All three‐dimensional in vitro mucosal models constructed, thus far, have only been reconstituted by epithelial cells. We have developed a reconstructed oral and vaginal epithelium that integrates Langerhans' cells (LC), the dendritic cells (DC) of malpighian epithelia. The epithelium was composed of gingival or vaginal keratinocytes seeded on a de‐epidermized dermis (DED) and grown in submerged culture for 2 weeks. LC precursors, obtained after differentiation of cord blood‐derived CD34+ hematopoietic progenitor cells (CD34+HPC) by granulocyte macrophage‐colony stimulating factor (GM‐CSF), tumor necrosis factor‐α (TNF‐α), transforming growth factor‐β (TGF‐β) and Flt3‐ligand (Flt3‐L), were introduced after 6–8 days of culture into the reconstituted epithelium. The in vitro reconstituted mucosal epithelium formed a multilayered, well‐differentiated epithelial structure, confirmed by the immunohistochemical expression of cytokeratins 4, 6, 10, 13, 14, 16 and involucrin. LC were identified in the basal and suprabasal epithelial layers by CD1a antigen, S100 protein and Langerin/CD207 expression, and by transmission electron microscopy. Type IV collagen was expressed at the chorio–epithelial junction, and most ultrastructural features of this junction were visualized by electron microscopy. This in vitro reconstructed gingiva or vagina integrating LC represents interesting models very similar to native tissues. Because LC play an important role in the mucosal immune system, our models could be useful for conducting studies on interactions with pathogenic agents (viruses, bacteria etc.), as well as in pharmacological, toxicological and clinical research.
Egalitarian Developmentalism, Communist Mobilization, and the Question of Caste in Kerala State, India

The article critiques the “Kerala model,” which holds up Kerala State, India, as a model that may be emulated by other developing countries, on account of its remarkable advances in social development. The dominant left in Kerala has often claimed credit for such achievements, leading to its glorification as a model for social democracy. This uncritical adoration, which has acquired the status of national commonsense in Kerala, has reduced marginalized people in Kerala, particularly the lower-caste Dalits and tribals, to a state of abjection. The present effort seeks to show how the marginalization of these social groups and their confinement to governmental categories was not a historical accident, but the effect of political strategies on the left that led to their exclusion from productive resources, and of the assertion of upper-caste agency in left-led anticaste struggle.
