Regional news media discourse: the experience of communicative and pragmatic analysis of text chains
Authors: Rogaleva Ol'ga Sergeevna 
Published: June 2024

The subject of the study is the peculiarities of the structure of the regional news discourse – the discourse of Omsk and the Omsk region. The text–centric approach made it possible to identify in the regional news discourse a structural unit larger than the text – the text chain. The architecture of the regional news media discourse is considered as a set of continuous messages, or chains of texts. A number of chronologically ordered events fit into discursive plots, "discursive fragments" combined semantically and functionally. At the same time, "in the development of each information story, it is important to trace the degree of its unfoldment: this will manifest its discoursogenicity (the ability to generate discourse). These text associations – chains – reflect both the specifics of the regional agenda and the communicative and pragmatic features of the news discourse of a particular region. Monitoring of regional Internet news resources made it possible to identify information causes that gave rise to chains of news texts, represented in the regional media discourse in the winter of 2023-2024. The analysis of the regional media space involves relying on a number of methods of discursive and linguistic analysis. The analysis technique is based on a structural approach to the analysis of a "discrete text stream" and involves the allocation of fragments in discourse, "quanta" – larger than the text. Content analysis allows us to identify discourse-forming plots and episodes, characters of the regional media discourse. The discursive plots and episodes represented in the news discourse of the Omsk region in the winter of 2024 are highlighted. Using the example of the analysis of two discursive plots, it is revealed that the chains of regional news texts are built around information occasions that have gained wide public resonance. As a result of the analysis of empirical material, it was found that the actions and statements of the authorities – the governor and the mayor – can be attributed to the nuclear composite block of news text chains in the regional media discourse. They are inscribed into the journalistic narrative as heroes, actors, and characters. Text chains may vary in volume and intensity. Being open-ended structures, text chains can be extended through collections of readers' comments. Grouping texts by information source made it possible to see the degree of variability in the communicative and pragmatic presentation of the event by news agencies.
The last word in strong correlations
Authors: Shankar R. 
Published: September 2011

AbstractIn the Fractional Quantum Hall Effect (FQHE), in the noninteracting limit, only a fraction ν of the Lowest Landau Level (LLL) is occupied, producing a huge degeneracy. Interactions lift this degeneracy and mix in higher LL's. In the limit in which we ignore all but the LLL (i.e., let the inverse electron mass 1/m → ∞), the kinetic energy is an irrelevant constant and the ratio of potential to kinetic energy is essentially infinite, making this the most strongly correlated problem imaginable. I give a telegraphic review of the Hamiltonian Theory of the FQHE developed with Ganpathy Murthy that deals with this problem with some success. A nodding acquaintance with FQHE physics is presumed.
Strong electron correlations in FeSb2
Authors: Sun P. , Søndergaard M. , Iversen B.B. , Steglich F. 
Published: September 2011

AbstractFeSb2 has been recently identified as a new model system for studying many‐body renormalizations in a d‐electron based narrow gap semiconducting system, strongly resembling FeSi. The electron‐electron correlations in FeSb2 manifest themselves in a wide variety of physical properties including electrical and thermal transport, optical conductivity, magnetic susceptibility, specific heat and so on. We review some of the properties that form a set of experimental evidences revealing a significant role of correlation effects in FeSb2. The metallic state derived from slight Te doping in FeSb2, which exhibits a large quasiparticle mass, will also be introduced.
Superperturbation theory on the real axis
Authors: Jung C. , Wilhelm A. , Hafermann H. , Brener S. , Lichtenstein A. 
Published: September 2011

AbstractIn this article we formulate the superperturbation theory for the Anderson impurity model on the real axis. The resulting impurity solver allows to evaluate dynamical quantities without numerical analytical continuation by the maximum entropy method or Padé approximants. This makes the solver well suited to study multiplet effects in solids within the dynamical mean field theory. First examples including multi‐orbital problems are discussed.
Anatomy practical examinations: How does student performance on computerized evaluation compare with the traditional format?
Authors: Inuwa Ibrahim Muhammad , Taranikanti Varna , Al‐Rawahy Maimouna , Habbal Omar 
Published: September 2011

AbstractPractical examinations in anatomy are usually conducted on specimens in the anatomy laboratory (referred to here as the “traditional” method). Recently, we have started to administer similar examinations online using the quiz facility in Moodle™. In this study, we compare student scores between two assessment environments viz. online and traditional environments. We hypothesized that regardless of the examination medium (traditional or online) overall student performance would not be significantly different. For the online medium, radiological images, prosected specimens, and short video clips demonstrating muscle action were first acquired from resources used for teaching during anatomy practical classes. These were optimized for online viewing and then uploaded onto Moodle learning management software. With regards to the traditional format, actual specimens were usually laid out in a circular stream. Identification tags were then attached to specific spots on the specimens and questions asked regarding those identified spots. A cohort of students taking practical examinations in six courses was studied. The courses were divided into three pairs with each pair credit‐weight matched. Each pair consisted of a course where the practical examination was conducted online and the other in the traditional format. There was no significant difference in the mean scores within each course pair. In addition, a significant positive correlation between score in traditional and online formats was found. We conclude that mean grades in anatomy practical examination conducted either online or in the traditional format were comparable. These findings should reassure teachers intending to use either format for their practical examinations. Anat Sci Educ. © 2011 American Association of Anatomists.
Collection of peripheral blood progenitor cells for autologous use: Performance enhancements of COBE spectra, auto‐PBSC
Authors: Sorensen Betina Samuelsen , Thomsen Anna‐Maria , Moller Bjarne Kuno 
Published: September 2011

AbstractCollection of peripheral blood stem cells (PBSC) must be performed in a safe and effective manner. Issues like automation, collection efficiency (CE), and adverse events must be considered. Auto‐PBSC (COBE Spectra) is a fully automated program for PBSC collection. Changes in the protocol were made to achieve high CE, low product volume, and resulted in three groups of patients. Standard operating procedures (SOPs) were developed to reduce citrate toxicity and patients with central venous catheter. Twenty patients and 27 collections (Group 1), 88 patients and 112 collections (Group 2), and 158 patients and 194 collections (Group 3) were recorded. The protocol changes increased CE significantly from 31% (Group 1) to 57 and 59% (Group 2 and 3). Adjusting endpoint according to the preapheresis number of CD34+ cells reduced the collection time and the volume of the product significantly (median 227 min and 56 mL) without affecting CE. Mean level of ionized calcium before collection was 1.22 mmol/L, measured in 31 patients. This declined to a mean of 1.07 mmol/L after 1 h of collection and remained unchanged despite continuous calcium infusion. The number of patients with mild symptoms of citrate toxicity was reduced from 20 to 6%. A central venous catheter was used in 15%. Compared to peripheral access no differences in blood flow rate or time to perform the collection were found. Changes in the Auto‐PBSC protocol resulted in an improved CE and a small product. SOPs reduced the number of patients with citrate toxicity and with central venous catheter. J. Clin. Apheresis, 2011. © 2011 Wiley Periodicals, Inc.
Systematic screening of BK virus by real‐time PCR prevents BK virus associated nephropathy in renal transplant recipients

Published: September 2011

AbstractBK virus associated nephropathy occurs in approximately 5% of renal transplant recipients. Quantitation of BKV DNA in serum/plasma early in the course of disease has been suggested to be an important diagnostic tool for polymavirus‐associated nephropathy (PVAN). The aim of this study was to develop a BKV real‐time PCR (qPCR), which could be included in a diagnostic qPCR platform. Additionally, the significance of the assay as a surrogate marker for PVAN was investigated. Quantitation of BKV DNA by qPCR was carried out on 234 serum samples from a retrospective study including 31 renal transplant recipients monitored for at least 6 months post‐transplantation. BKV viremia was detected in 9 out of 31 patients. Four patients had a viral load of >10,000 copies/ml at least on one occasion. In two of these patients, PVAN was diagnosed clinically during the study period. In retrospect, these patients were shown to be BKV positive before the clinical diagnosis of PVAN was made. Another two patients had a permanent graft dysfunction, but were never clinically diagnosed with PVAN. None of the remaining five patients with BKV DNA (<10,000 copies/ml) had renal impairment. Based on these results, an algorithm was introduced at the study center in 2006 and to date, August 2011, no cases of PVAN with loss of graft have been observed. The concept of including different PCR protocols in a common qPCR platform allows laboratories with small sample numbers to perform regularly a variety of assays at a reasonable cost. J. Med.

Published: September 2011

SUMMARYThe two‐level discrete complex image method (DCIM) is successfully introduced into the marine controlled‐source electromagnetic (MCSEM) survey. The original integral path does not hold valid in extremely low‐frequency situation, and the reason can be ascribed to the change of wave number at different frequencies. The new integral path suitable for the extremely low‐frequency situation is proposed. This paper focuses on the selection of parameters, including the sampling space, the sampling number, and the number of exponential terms. The study shows that the effects of these parameters are different on different paths. The appropriate ranges of these parameters are proposed. In order to validate the DCIM, we calculated the electric field of a five‐layer model under different frequency situations. The electric field attenuates faster with frequency increase. The effect of oil‐layer conductivity is studied, and the results show that the electric field is stronger with lower oil conductivity. All the results accord to the physical meanings of MCSEM. The model with multiple objects is studied to find the effect of shallow resistor on the detection ability of MCSEM. Copyright © 2011 John Wiley & Sons, Ltd.

AbstractSafinamide is an α‐aminoamide with both dopaminergic and nondopaminergic mechanisms of action evaluated as an add‐on to dopamine agonist (DA) therapy in early‐stage PD. In this 24‐week, double‐blind study, patients with early PD receiving a stable dose of a single DA were randomized to once‐daily safinamide 100 mg, safinamide 200 mg, or placebo. The primary efficacy variable was UPDRS part III (motor examination) total score. Analysis was hierarchical: 200 mg of safinamide versus placebo was tested first; the success of safinamide 100 mg versus placebo was contingent on this. Two hundred sixty‐nine patients received safinamide 100 mg (n = 90), safinamide 200 mg (n = 89), or placebo (n = 90); 70, 81, and 81 patients, respectively, completed the study. Mean improvements from baseline to week 24 in UPDRS III total scores were −3.90 for safinamide 200 mg, −6.0 for safinamide 100 mg and −3.60 for placebo. The difference between safinamide 200 mg and placebo was not significant [point estimate: −0.4; 95% confidence interval (CI): −2.3–1.4; P = 0.6504]. Although the difference between 100 mg/day and placebo was significant (point estimate: −1.9; 95% CI: −3.7 to −0.1; P = 0.0419), these results are considered exploratory. No clinically meaningful differences from placebo were observed for any safety variables. This study did not demonstrate a significant improvement of the primary endpoint for safinamide 200 mg/day. Exploratory analysis of the primary endpoint for 100 mg/day demonstrated that the addition of safinamide to a stable dose of DA improves motor symptoms in early PD and warrants further investigation. © 2011 Movement Disorder Society
Micromechanical discrete element modeling of fiber reinforced polymer composites
Authors: Khattab Ahmed , Khattak Mohammad J. , Fadhil Imran M. 
Published: September 2011

AbstractAn analytical model of mechanical behavior of carbon fiber reinforced polymer composites using an advanced discrete element model (DEM) coupled with imaging techniques is presented in this article. The analysis focuses on composite materials molded by vacuum assisted resin transfer molding. The molded composite structure consists of eight‐harness carbon fiber fabrics and a high‐temperature polymer. The actual structure of the molded material was captured in digital images using optical microscopy. DEM was developed using the image‐based‐shape structural model to predict the composite elastic modulus, stress–strain response, and compressive strength. An experimental case study is presented to evaluate the accuracy of the developed analytical model. The results indicate that the image‐based DEM micromechanical model showed fairly accurate predictions for the elastic modulus and compressive strength. POLYM.

Effect of stress transfer between fiber and matrix on toughness of polymer composite
Authors: Ichinose Noriyo , Ishikawa Masaru , Morimoto Kiyoshi 
Published: September 2011

AbstractThanks to their lightweight properties, formability and low cost, polymers have become an essential material for manufactured products. To improve the mechanical properties, almost all polymers are blended with some kind of fiber made from glass, carbon, organic or natural material. The importance of interfacial strength between matrix and fiber is a well known requirement for effective mechanical properties and some experimental results indicate that low interfacial strength helps increase the toughness of composites. In this paper, models of composite reinforced by fiber aligned with maximum principal stress under uni‐tensile loading are simulated. Based on the simulation result, we discuss the effect of interfacial strength, aspect ratio of fiber and friction force between matrix and fiber on stable deformation and provide the guidelines for establishing composites with high modulus and toughness.

Feeding ecology of striped dolphins, Stenella coeruleoalba, in the north-western Mediterranean Sea based on stable isotope analyses

Published: September 2011

The feeding ecology of striped dolphin, Stenella coeruleoalba, in the north-western Mediterranean Sea was studied using stable isotope analyses. Carbon and nitrogen stable isotope ratios were measured in skin and muscle tissues of stranded and by-caught dolphins from six geographical areas in the Mediterranean Sea and Atlantic Ocean. Variation in δ15N in relation to dolphin size is attributed to changes in diet. Nursing calves have a higher trophic level than weaned animals and their δ15N values decrease progressively until weaning, estimated to be at a body length of around 155 cm. δ15N values then increased for larger individuals which suggests changes in diet for mature dolphins. Geographical differences in diet were apparent between the Atlantic and the Mediterranean, although no clear differences were apparent between the five Mediterranean areas. Comparisons of the nitrogen isotope ratios of skin and muscle highlighted a higher fractionation in skin compared to the muscle tissue. Values of δ13C also increased with body length although it appears that this is not only driven by trophic level enrichment. δ13C increases before weaning and the difference in trophic level between newly-weaned and mature dolphins was twice as high for carbon as for nitrogen. Ontogenetic changes in carbon isotope composition may therefore be driven by feeding on deep water prey and dolphin movements outside the coastal feeding grounds. Indeed, seasonal variations in δ13C are suspected to be driven by migration within the Mediterranean basin.

Published: September 2011

AbstractPiezoelectric nanoactuators, which can provide extremely stable and reproducible positioning, are rapidly becoming the dominant means for position control in transmission electron microscopy. Here we present a second-generation miniature goniometric nanomanipulation system, which is fully piezo-actuated with ultrafine step size for translation and rotation, programmable, and can be fitted inside a hollowed standard specimen holder for a transmission electron microscope (TEM). The movement range of this miniaturized drive is composed of seven degrees of freedom: three fine translational movements (X,Y, andZaxes), three coarse translational movements along all three axes, and one rotational movement around theX-axis with an integrated angular sensor providing absolute rotation feedback. The new piezoelectric system independently operates as a goniometer inside the TEM goniometer.In situexperiments, such as tomographic tilt without missing wedge and differential tilt between two specimens, are demonstrated.

Abstract
Summary: Metavir is a web server dedicated to the analysis of viral metagenomes (viromes). In addition to classical approaches for analyzing metagenomes (general sequence characteristics, taxonomic composition), new tools developed specifically for viral sequence analysis make it possible to: (i) explore viral diversity through automatically constructed phylogenies for selected marker genes, (ii) estimate gene richness through rarefaction curves and (iii) perform cross-comparison against other viromes using sequence similarities. Metavir is thus unique as a platform that allows a comprehensive virome analysis.

SummaryContext  Human growth hormone receptor (GHR) transcripts have two isoforms, full‐length (GHRfl) or exon 3 deleted (GHRd3). An association of these isoforms has been found with small for gestational age (SGA) infants but does not influence adult height. The role of this polymorphism in the birth size spectrum in the general population is unclear.Objective  To determine the association of maternal and infants GHR exon 3 polymorphism with antenatal growth, birth size and early postnatal growth in two large, normal white European birth cohorts.Study design  Pregnant women from white European families were recruited by the University College London Foetal Growth Study (n = 774) and the Moore normal pregnancy cohort (n = 274). GHR variants, wild‐type (fl) and deleted for exon 3 (d3) were analysed using multiplex PCR.Results  There was a significant underrepresentation of infants wild‐type fl/fl (36%) and overrepresentation of d3/d3 (14%) genotypes in the SGA infants within the cohorts (χ2 = 11·2, P = 0·003, df = 2). Fl/fl was overrepresented in large for gestational age (LGA) infants (χ2 = 6·1, P = 0·047, df = 2). There was a significant association of infants GHR isoforms with placental weight (P < 0·001) and birth weight standard deviation scores (P = 0·04) with the fl/fl genotype associated with a larger placental and birth weight. In multiple regression analysis, the GHR isoform type, maternal booking weight and parity influenced placental weight (R2 = 0·35; P < 0·001, df = 7). The GHR isoform type was not related to antenatal anthropometric measurements or growth in infancy.Conclusion  These data suggest that the GHR isoforms are associated with placental and birth weight.
