Authors: Takahashi Wataru , Yao Jen-Chih 
Published: June 2015

AbstractIn this paper, we consider the split common null point problem in Banach spaces. Then using the hybrid method and the shrinking projection method in mathematical programming, we prove strong convergence theorems for finding a solution of the split common null point problem in Banach spaces.
Structural Transition of pH-responsive Poly(l-lysine) Hydrogel Prepared via Chemical Crosslinking
Authors: Matsumoto Kazuya , Kawamura Akifumi , Miyata Takashi 
Published: June 2015

Abstract
Poly(l-lysine) (PLL) undergoes structural change from α-helix to random coil in response to a change in pH in an aqueous solution. By chemical crosslinking of PLL with ethylene glycol diglycidyl ether (EGDE), we prepared pH-responsive hydrogels that undergo a change in volume and conformation between α-helix and random coil in response to a change in pH. The difference in transition pH between a PLL linear polymer and a PLL hydrogel revealed that chemical crosslinking stabilized the helical structure of PLL chains in hydrogel networks.

Published: June 2015

AbstractBACKGROUNDNonfasting triglycerides are similar or superior to fasting triglycerides at predicting cardiovascular events. However, diagnostic cutpoints are based on fasting triglycerides. We examined the optimal cutpoint for increased nonfasting triglycerides.METHODSWe obtained baseline nonfasting (&lt;8 h since last meal) samples from 6391 participants in the Women's Health Study who were followed prospectively for ≤17 years. The optimal diagnostic threshold for nonfasting triglycerides, determined by logistic regression models by use of c-statistics and the Youden index (sum of sensitivity and specificity minus 1), was used to calculate hazard ratios (HRs) for incident cardiovascular events. Performance was compared to thresholds recommended by the American Heart Association (AHA) and European guidelines.RESULTSThe optimal threshold was 175 mg/dL (1.98 mmol/L), with a c-statistic of 0.656, statistically better than the AHA cutpoint of 200 mg/dL (c-statistic 0.628). For nonfasting triglycerides above and below 175 mg/dL, after adjusting for age, hypertension, smoking, hormone use, and menopausal status, the HR for cardiovascular events was 1.88 (95% CI 1.52–2.33, P &lt; 0.001), and for triglycerides measured at 0–4 and 4–8 h since the last meal, 2.05 (1.54– 2.74) and 1.68 (1.21–2.32), respectively. We validated performance of this optimal cutpoint by use of 10-fold cross-validation and bootstrapping of multivariable models that included standard risk factors plus total and HDL cholesterol, diabetes, body mass index, and C-reactive protein.CONCLUSIONSIn this study of middle-aged and older apparently healthy women, we identified a diagnostic threshold for nonfasting hypertriglyceridemia of 175 mg/dL (1.98 mmol/L), with the potential to more accurately identify cases than the currently recommended AHA cutpoint.

Published: June 2015

Abstract
Intercalation of sodium into the carbon lining of aluminium electrolysis cells is a common cause of its failure. The effect of sodium on model carbon cathode materials was studied in the system with high activity of sodium (molten NaF–NaCl system). Commercially available carbon materials such as semigraphite and electrographite (Kompozitum, Topol’čany, SK) were chosen as model cathodes. The experiments were carried out at a constant cathode current density of 0.7 A cm−2. A modified Rapoport test was developed and used to study the expansion of the chosen types of carbon materials.
GNSS Receivers, Theirs Features, User Environment And Applications
Authors: Januszewski Jacek 
Published: June 2015

AbstractSince many years the coordinates of the position can be obtained with the use of satellite navigation and augmentation systems, SNS and SBAS, respectively. All these systems are called GNSS (Global Navigation Satellite Systems). The main task of the user segment is to transform the products delivered by the GNSS infrastructure into services that users are mainly interested in. That's why GNSS receiver selection depends on user application. Nowadays several hundred different receivers provided by more than one hundred manufacturers are available on the world market. The review of the performance parameters of GNSS receivers accessible in 2014 and last three years is presented in this paper. Additionally the paper gives the reply to some important questions as: for how many applications the given model is destined, which is the percentage of the receivers designed for marine and navigation users, which equipment features of the receiver are the most important for given application, which satellite signals apart from GPS signals can be tracked in the receiver?
Pro unitality and pro excision in algebraic K-theory and cyclic homology
Authors: Morrow Matthew 
Published: June 2015

Abstract
The purpose of this paper is to study pro excision in algebraic K-theory and cyclic homology, after Suslin–Wodzicki, Cuntz–Quillen, Cortiñas, and Geisser–Hesselholt, as well as continuity properties of André–Quillen and Hochschild homology. A key tool is first to establish the equivalence of various pro Tor vanishing conditions which appear in the literature.
This allows us to prove that all ideals of commutative, Noetherian rings are pro unital in a suitable sense. We show moreover that such pro unital ideals satisfy pro excision in derived Hochschild and cyclic homology. It follows hence, and from the Suslin–Wodzicki criterion, that ideals of commutative, Noetherian rings satisfy pro excision in derived Hochschild and cyclic homology, and in algebraic K-theory.

In addition, our techniques yield a strong form of the pro Hochschild–Kostant–Rosenberg theorem; an extension to general base rings of the Cuntz–Quillen excision theorem in periodic cyclic homology; a generalisation of the Feĭgin–Tsygan theorem;
a short proof of pro excision in topological Hochschild and cyclic homology; and new Artin–Rees and continuity statements in André–Quillen and Hochschild homology.
The dynamics of stiff clubmoss Lycopodium annotinum L. patches in clumps of trees left on the clear-cutting in pine forest Leucobryo-Pinetum

Abstract
Clumps of trees left on the clear-cuttings have an important role in protecting populations of endangered plant species against destruction during silviculture activities. The aim of this study is to describe the changes in the area of the Lycopodium annotinum patches. The area of L. annotinum patch in clump of trees, have been significantly reduced during 5 years after clear-cut. In the first year of the observations, the studied population occupied an area of 69.8 m2 whereas in 2012, it was only 37.5 m2. Most of the shoots were withered away on the south side of the clump. The probable reason was too strong insolation. Shoots that survived were located in the north part of the clump – shielded by young trees and shrubs layer. At this time, the control patch of L. annotinum located inside the forest increased its area. Before the clear-cuttings, the annual growth of vertical shoots of clubmoss was higher in the patch located in future tree clump. After the clear-cutting, growth of shoots in this patch was shorter than in patch located all the time inside the forests. The most effective growth was observed in the third studied patch located in the clear-cutting border. The explanation for this phenomenon could be the higher humidity of habitat on this site. Clumps of trees left after the clear-cutting contribute to the protection of endangered populations, but do not eliminate the significant microhabitat changes. The clubmoss patches located in moist habitats are more likely to survive even if they are partially exposed to the sunlight.
Evaluation Of Emotional State, Heart Rate Frequency And Skiing Technique In Ski Hiking

Published: June 2015

Abstract

Introduction
. The aim of this study was to assess selected psychological, physiological and technical factors related to ski hiking in order to offer some recommendations for ski hikers and ski hike organisers.

Material and methods
. The hike lasted 8 hours and the hikers covered a distance of 24 kilometres. The ski hikers' emotional state was assessed three times: before the ski hike, 1 hour after the hike and 16 hours after the hike. Their skiing technique was evaluated during the first part of the hike and at the end of the hike. The heart rate of the skiers was recorded over the course of the hike. The data were then processed and analysed statistically.

Results
. When comparing the data collected for the selected factors during the ski hike, some significant correlations were found. A significant correlation was observed between the level of fear experienced before the ski hike and cycle length for the diagonal stride (r=−0.791, p<0.05), which meant that the hikers with poorer ski technique felt more afraid before the hike. However, these hikers also showed lower levels of sadness 16 hours after the hike (r=0.804, p<0.05). A significant negative correlation (r=−0.849, p<0.05) was found when comparing the average heart rate frequency and the level of anger experienced after the hike, that is the hikers who had a lower heart rate were angrier after the hike. The results helped to develop some important recommendations for ski hikers and ski hike organisers.
Building Critical Community Engagement through Scholarship: Three Case Studies
Authors: Findlay Isobel M. , Lovrod Marie , Quinlan Elizabeth , Teucher Ulrich , Sayok Alexander K. , Bustamante Stephanie , Domsby Darlene 
Published: June 2015

Drawing on a shared recognition that community is defined, understood, constructed, and reconstructed through contextually inflected relationships, collaborating authors use diverse interdisciplinary case studies to argue that rigorous community-engaged scholarship advances capacities for critical pursuit of cognitive and social justice. Whether through participant-centred projects undertaken with youth in government care networks, cross-cultural explorations of Indigenous and non-Indigenous science and culture as resources for food security, or facilitated dramatizations of community relations impacted by neo-liberal ideologies, contributors affirm welcoming co-learning environments that engage multiple forms of knowledge expression and mobilization. The respectful spaces held in these community-researcher collaborations enable new advances beyond hegemonic knowledge development institutionalized through colonialist histories. This essay theorizes prospects for building transformative community through scholarship, citing practical examples of the principles and practices that foster or frustrate sustainable communities. It explores the institutional arrangements and power dynamics between and among actors, asking who gets included and excluded, and what boundaries are created and crossed around complex, contradictory, and contested notions of â€œcommunity.â€Â Â
Population genetic variation, geographic structure, and multiple origins of autopolyploidy in Galax urceolata

Published: June 2015

• Premise of the study: Whereas population genetic studies have examined allopolyploids, comparable studies of naturally occurring autopolyploids remain rare. To address fundamental questions regarding autopolyploidy, we undertook a detailed population genetic study of one of the classic examples of autopolyploidy, Galax urceolata (Diapensiaceae), which comprises diploid, triploid, and autotetraploid cytotypes. Galax is endemic to the Appalachian Mountains, the adjacent piedmont, sandhills, and coastal plain and represents perhaps the most widely known example of autopolyploidy in nature.• Methods: Flow cytometry was used to diagnose ploidal level of ∼1000 individuals across 71 populations. We used 10 microsatellite markers to examine genetic variation across the geographic range of Galax and assessed multiple origins though comparisons of diploid, triploid, and tetraploid accessions using multiple analytical approaches.• Key results: Tetraploids had higher levels of heterozygosity than diploids did. Genetic variation in diploid and tetraploid Galax is geographically structured among the ecoregions of the southeastern United States. Autotetraploidy in Galax urceolata has occurred independently at least 46 times, with triploidy having occurred a minimum of 31 times.• Conclusions: Genetic differentiation among ecoregions suggests historical patterns of local adaptation. The numerous independent origins of tetraploid Galax reported here are among the highest frequencies of independent polyploidizations ever reported for any polyploid (auto‐ or allopolyploid).
Altérations et virilité
Authors: Fabriol Anaïs 
Published: June 2015

Comme toute zone frontalière qui se respecte, les États du nord-ouest du Mexique ont construit une partie de leur attractivité grâce au tourisme érotique, que ce soit à travers des lupanars ou, ultérieurement, des sex-shops. Si ce processus a permis de constituer des imaginaires urbains autour de corps de prostituées féminines, et donc d’exalter une apparence physique spécifique consacrée au plaisir, en revanche, il semblerait que peu à peu, cette représentation de la femme sexuée se transfigure en mise en perspective du mâle féminisé, ou du moins réduit à des attributs/codes de séduction appartenant aux deux sexes : soit un homme-objet sportif, à la limite du gigolo, fait pour attirer les convoitises féminines, soit un homosexuel ou bisexuel, soit, paroxysme du borderline, le travesti ou vestida, encore plus beau et féminin qu’une femme, sorte de figure érotique par antonomase. Dès lors, il convient de nous interroger sur les représentations qu’engendrent ces êtres autant à la limite que l’univers dans lequel ils vivent, les désirs qu’ils suscitent et les constructions diégétiques qu’ils appellent. Sont-ils la métaphore d’une identité déjà mouvante ou le symbole de la disparition de l’archétype du macho latino ? Ou bien sont-ils encore une forme altérée du personnage postmoderne ?L’étude porte principalement sur trois ouvrages narratifs : la nouvelle « Marcos » du recueil Desnudamente Roja (2010) de Rosina Conde, et les romans 41 closets (2005) de Heriberto Yépez et Travesti (2009) de Carlos Reyes Ávila.
De la censure à l’autocensure
Authors: Prioul Françoise 
Published: June 2015

Cette étude diachronique et comparative de la poésie du tango et de la danse montre comment un genre né de grands bouleversements psychologiques et sociaux, objet de critiques acerbes car révélatrices d’enjeux fondamentaux, crée ses propres mécanismes d’autocensure, qui permettent un équilibre essentiel entre prohibition et transgression, pulsions érotiques et contrôle social. Ce sont ces mécanismes eux-mêmes, endogènes, qui créent les conditions de possibilité d’un érotisme supérieur car sublimé dans l’art.L’étude s’appuie sur des traités de danse, des descriptions littéraires, des témoignages de danseurs de la première moitié du xxe siècle. L’étude dégage quelques éléments sémiotiques de cette tension : enjeu identitaire, argentin mais aussi peut-être universel car ancré dans un invariant inconscient et psychique, ce qui permettrait de comprendre en partie la longévité et l’ampleur géographique et culturelle de ce genre artistique.
Erotismo, registro popular e hibridismo de lenguajes escénicos en La Negra Ester de Roberto Parra y Andrés Pérez
Authors: Obregón Osvaldo 
Published: June 2015

La Negra Ester fue estrenada en 1988 por el Gran Circo Teatro en Puente Alto, comuna periférica de Santiago de Chile y representada después en la Terraza Caupolicán del Cerro Santa Lucía en pleno centro de la capital; en ambos lugares el espacio teatral fue una carpa o «chapiteau» sin techo. También ha ocupado posteriormente salas convencionales. Al cabo de una prolongada difusión nacional e internacional (Canadá, Francia, Escocia, Italia, Suiza, Colombia) ha llegado a ser un montaje emblemático del teatro chileno de los últimos decenios. Nuestro análisis se centra tanto en la adaptación dramatúrgica como en el montaje. Desarrolla los siguientes aspectos: 1) El tema del erotismo en La Negra Ester, con referencia a conceptos de Georges Bataille en su libro L’érotisme; 2) Los rasgos formales de la dramaturgia textual; y 3) La puesta en escena de Andrés Pérez.
L’érotisation du monde et l’affirmation identitaire chez Gregorio Martínez
Authors: Salinas-Desmond Patricia 
Published: June 2015

Le monde que Gregorio Martínez met en scène, celui de la population rurale de sa terre natale de Coyungo, près de Nazca, révèle un imaginaire rural et des comportements irrigués par des rapports intenses à la nature, à la fertilité, au corps, à la vie et à la sexualité, venus en droite ligne de la mère Afrique. Avec toujours, comme dans les chants, les musiques, les danses et les « décimas », l’humour burlesque et la caricature, le rire et la moquerie. Chez Grégorio Martínez, cette affirmation identitaire et ce rapport solaire et cosmique singulier de l’homme avec la nature passent par la femme, souvent délaissée, trompée et insatisfaite par les hommes. Personnage central de la société, sa plus grande humanité, son humour et son érotique subvertissent les hiérarchies et s’affirment ironiquement face à la domination des mâles.
De la prévention situationnelle au predictive policing
Authors: Benbouzid Bilel 
Published: June 2015

Cet article traite d’un corpus de textes scientifiques correspondant à un moment important dans le processus de légitimation de la prévention situationnelle : les recherches sur la victimisation à répétition et la construction d’algorithmes de prédiction. Le corpus permet de mettre en scène une controverse souvent ignorée, opposant Ken Pease et Tim Hope, relative à l’interprétation de résultats issus de la modélisation statistique de la distribution de la victimisation dans la population. Mise en perspective avec les résultats des recherches de Ken Pease et ses collaborateurs, la critique de Tim Hope permet de rendre compte de l’ignorance qui évolue avec le développement des connaissances sur la prédiction des victimisations et des innovations qui leur sont associées. En conclusion, il est fait appel à une définition des politiques publiques de prévention et de sécurité non pas à partir des connaissances produites par les experts, mais à partir d’un accord rendu public sur leurs désaccords.

Abstract
Genotoxic stress can promote antitumor NK cell responses by upregulating the surface expression of activating ligands on cancer cells. Moreover, a number of studies suggested a role for soluble NK group 2D ligands in the impairment of NK cell tumor recognition and killing. We investigated whether genotoxic stress could promote the release of NK group 2D ligands (MHC class I–related chain [MIC]A and MICB), as well as the molecular mechanisms underlying this event in human multiple myeloma (MM) cells. Our results show that genotoxic agents used in the therapy of MM (i.e., doxorubicin and melphalan) selectively affect the shedding of MIC molecules that are sensitive to proteolytic cleavage, whereas the release of the short MICA*008 allele, which is frequent in the white population, is not perturbed. In addition, we found that a disintegrin and metalloproteinase 10 expression is upregulated upon chemotherapeutic treatment both in patient-derived CD138+/CD38+ plasma cells and in several MM cell lines, and we demonstrate a crucial role for this sheddase in the proteolytic cleavage of MIC by means of silencing and pharmacological inhibition. Interestingly, the drug-induced upregulation of a disintegrin and metalloproteinase 10 on MM cells is associated with a senescent phenotype and requires generation of reactive oxygen species. Moreover, the combined use of chemotherapeutic drugs and metalloproteinase inhibitors enhances NK cell–mediated recognition of MM cells, preserving MIC molecules on the cell surface and suggesting that targeting of metalloproteinases in conjunction with chemotherapy could be exploited for NK cell–based immunotherapeutic approaches, thus contributing to avoid the escape of malignant cells from stress-elicited immune responses.
