Pro-ana versus Pro-recovery: A Content Analytic Comparison of Social Media Users’ Communication about Eating Disorders on Twitter and Tumblr

Objectives: To compare how people communicate about eating disorders on two popular social media platforms – Twitter and Tumblr. Materials and Methods: Thematic analysis was conducted to characterize the types of communications posted, and a content analysis was undertaken of between-platform differences. Results: Three types of content (pro-ana, anti-ana, and pro-recovery) were posted on each platform. Overall, across both platforms, extreme pro-ana posts were in the minority compared to anti-ana and pro-recovery. Pro-ana posts (including ‘thinspiration’) were more common on Twitter than Tumblr, whereas anti-ana and pro-recovery posts were more common on Tumblr. Conclusion: The findings have implications for future research and health care relating to the treatment and prevention of eating disorders. Developers of future interventions targeting negative pro-ana content should remain aware of the need to avoid any detrimental impact on positive online support.
Passive Double-Sensory Evoked Coherence Correlates with Long-Term Memory Capacity

HIGHLIGHTS Memory correlates with the difference between single and double-sensory evoked steady-state coherence in the gamma range (ΔC). The correlation is most pronounced for the anterior brain region (ΔCA). The correlation is not driven by birth size, education, speed of processing, or intelligence. The sensitivity of ΔCA for detecting low memory capacity is 90%. Cerebral rhythmic activity and oscillations are important pathways of communication between cortical cell assemblies and may be key factors in memory. We asked whether memory performance is related to gamma coherence in a non-task sensory steady-state stimulation. We investigated 40 healthy males born in 1953 who were part of a Danish birth cohort study. Coherence was measured in the gamma range in response to a single-sensory visual stimulation (36 Hz) and a double-sensory combined audiovisual stimulation (auditive: 40 Hz; visual: 36 Hz). The individual difference in coherence (ΔC) between the bimodal and monomodal stimulation was calculated for each subject and used as the main explanatory variable. ΔC in total brain were significantly negatively correlated with long-term verbal recall. This correlation was pronounced for the anterior region. In addition, the correlation between ΔC and long-term memory was robust when controlling for working memory, as well as a wide range of potentially confounding factors, including intelligence, length of education, speed of processing, visual attention and executive function. Moreover, we found that the difference in anterior coherence (ΔCA) is a better predictor of memory than power in multivariate models. The sensitivity of ΔCA for detecting low memory capacity is 92%. Finally, ΔCA was also associated with other types of memory: verbal learning, visual recognition, and spatial memory, and these additional correlations were also robust enough to control for a range of potentially confounding factors. Thus, the ΔC is a predictor of memory performance may be useful in cognitive neuropsychological testing.
Reduction of geometric and intensity distortions in echo‐planar imaging using a multireference scan

Echo‐planar imaging (EPI) is very sensitive to patient‐induced field inhomogeneity caused by susceptibility changes between different anatomical regions. This results in geometric and intensity distortions in the image, especially near tissue/ air and tissue/bone interfaces. A new approach is presented to reduce geometric and intensity distortions in EPI. A phaseencoded multireference scan is used to estimate the amplitude and phase errors in the measured signals due to the field inhomogeneity. The EPI data is corrected using both the amplitude and phase of the measured errors. This technique has been evaluated using EPI pulse sequences implemented with conventional gradients and implemented with imaging systems that have special resonating gradients and fast analog to digital converters. The results in both phantom and human studies show that in the absence of object motion the new correction technique can effectively reduce the geometric and intensity distortions.
A broadband microstrip-to-CPW transition

A broadband microstrip-to-coplanar waveguide transition (CPW) is proposed in this paper. The ground shaping technique, which emphasizes the field matching, is employed in our proposed design. The shape of the backed ground plane varies gradually which can result in a smooth field transition. Simulation results are presented and they show that the transition can achieve a broad bandwidth. This transition can be very useful in various applications due to its compatibility with RF system-on-a chip, low loss performance, low cost and ease of fabrication.
Ischemia/Reperfusion‐Induced Granulocyte Influx is a Multistep Process Mediated by Mast Cells

Objective: The influx of polymorphonuclear leukocytes (PMNs) that occurs at the onset of reperfusion of postischemic tissue is a multistep mechanism that includes initial rolling of PMNs, a progressive reduction in PMN rolling velocity, and ultimately PMN adhesion and emigration. In this study we assessed whether mast cells play a role in reperfusion‐induced PMN recruitment with emphasis on PMN rolling, adhesion, and emigration.
Substance P increases catecholamine secretion from perfused rat adrenal glands evoked by prolonged field stimulation.

1. We have studied the effect of substance P (SP) on catecholamine (CA) secretion evoked by prolonged field stimulation from the perfused rat adrenal gland in vitro. 2. Previous studies show that SP has an inhibitory effect on the nicotinic response in a number of different tissue preparations. In the present study, we found that SP at concentrations from 10(‐7) to 10(‐6) M markedly increased CA secretion evoked by prolonged high‐frequency field stimulation but not that evoked by low‐frequency field stimulation. 3. In the absence of field stimulation SP by itself had no direct effect on CA secretion. This indicates that SP acts as a neuromodulator rather than a neurotransmitter to increase CA secretion from the adrenal medulla. 4. The nicotinic receptors were still functional following a period of prolonged field stimulation (120 min) because CA secretion was markedly increased in response to the nicotinic agonist dimethylphenylpiperazinium (DMPP). 5. Capsaicin pre‐treatment reduced CA secretion evoked by prolonged field stimulation and the facilitatory action of SP on CA secretion lasted longer in these capsaicin‐pre‐treated rats than in controls, indicating that SP‐containing capsaicin‐sensitive fibres innervating the adrenal medulla may be involved in the regulation of CA secretion. 6. In parallel with the increase in CA secretion, 3H overflow from the splanchnic nerve pre‐labelled with [3H]choline was also increased by SP. The increase in CA secretion by SP lasted longer than the increase in 3H overflow. These results suggest that SP facilitates CA secretion from the adrenal gland at two levels: (1) pre‐synaptically by facilitating ACh release from splanchnic nerve terminals, and (2) post‐synaptically by modulating the nicotinic secretory response by protection against nicotinic desensitization of secretion. 7. The present studies provide further evidence that endogenous SP in the splanchnic nerve may modulate CA secretion during stress.
Cartographie des zones inondables dans un contexte de changements climatiques : cas de la Rivière du Nord à Lachute

La caracterisation de l'evolution des crues de la riviere du Nord a ete effectuee avec le modele hydrologique Hydrotel. Les projections climatiques pour les horizons 2020, 2050 et 2080 ont ete obtenues de 3 MCG et de plusieurs scenarios d'emissions de GES. Par rapport a la periode 1967-1990, la principale observation pour la periode printaniere concerne la tendance a une reduction des quantiles des crues de recurrences inferieures a 20 ans. Parallelement, les quantiles de crues de recurrence superieure a 20 ans peuvent augmentes. Pour la periode hivernale, une augmentation marquee des quantiles de crues est prevue, notamment pour les faibles recurrences. Un troncon de la riviere du Nord a la hauteur de Lachute a ete modelise a l'aide du modele hydraulique unidimensionnel HEC-RAS. Les problematiques d'incertitudes et d'evolution du regime des crues, imputable aux changements climatiques, ont ete illustrees a travers la delimitafion des zones inondables.
ON THE TIME EVOLUTION OF THE LOCAL FLOW TOPOLOGY IN A TURBULENT BOUNDARY LAYER

The average rates of change of the invariants of the velocity gradient tensor (Q and R) have been determined experimentally in the outer layer of a turbulent boundary layer as a function of the invariants themselves. Subsequent integration yields trajectories in the QR plane describing the average evolution of the local flow topology following a fluid particle. The trajectories reveal inward spiralling orbits around and converging to the origin. The orbit’s period is nearly constant at 14. 3δ/Ue, which may be regarded as the characteristic lifetime of the energy containing eddies in this part of the boundary layer. Furthermore, an empirical model for the average Q and R evolution is presented that reproduces the main features of the orbits in the vicinity of the origin.
Synchrotron microbeam radiation therapy for rat brain tumor palliation—influence of the microbeam width at constant valley dose

To analyze the effects of the microbeam width (25, 50 and 75 µm) on the survival of 9L gliosarcoma tumor-bearing rats and on toxicity in normal tissues in normal rats after microbeam radiation therapy (MRT), 9L gliosarcomas implanted in rat brains, as well as in normal rat brains, were irradiated in the MRT mode. Three configurations (MRT25, MRT50, MRT75), each using two orthogonally intersecting arrays of either 25, 50 or 75 µm wide microbeams, all spaced 211 µm on center, were tested. For each configuration, peak entrance doses of 860, 480 and 320 Gy, respectively, were calculated to produce an identical valley dose of 18 Gy per individual array at the center of the tumor. Two, 7 and 14 days after radiation treatment, 42 rats were killed to evaluate histopathologically the extent of tumor necrosis, and the presence of proliferating tumors cells and tumor vessels. The median survival times of the normal rats were 4.5, 68 and 48 days for MRT25, 50 and 75, respectively. The combination of the highest entrance doses (860 Gy per array) with 25 µm wide beams (MRT25) resulted in a cumulative valley dose of 36 Gy and was excessively toxic, as it led to early death of all normal rats and of ∼50% of tumor-bearing rats. The short survival times, particularly of rats in the MRT25 group, restricted adequate observance of the therapeutic effect of the method on tumor-bearing rats. However, microbeams of 50 µm width led to the best median survival time after 9L gliosarcoma MRT treatment and appeared as the better compromise between tumor control and normal brain toxicity compared with 75 µm or 25 µm widths when used with a 211 µm on-center distance. Despite very high radiation doses, the tumors were not sterilized; viable proliferating tumor cells remained present at the tumor margin. This study shows that microbeam width and peak entrance doses strongly influence tumor responses and normal brain toxicity, even if valley doses are kept constant in all groups. The use of 50 µm wide microbeams combined with moderate peak doses resulted in a higher therapeutic ratio.
Un examen du role du capital public dans la production

La presente etude a pour but de determiner si le taux des obligations d'Etat a long terme peut ou non etre raisonnablement employe comme taux de rendement du capital public dans le calcul du produit interieur brut du secteur public. Elle indique que le taux de rendement du capital public est souvent plus faible que celui publie et qu'il concorde approximativement avec celui du capital prive. Etant donne qu'il existe une gamme d'estimations plausibles, nous concluons que le taux des obligations d'Etat a long terme pourrait etre utilise comme estimation prudente du taux de rendement de l'infrastructure publique. Des etudes anterieures ont revele que les estimations fondees sur la fonction de production ont tendance a donner des taux de rendement incroyablement eleves, tandis que celles fondees sur la fonction de cout semblent fournir des resultats plus raisonnables. Nous montrons dans le present document que la croissance du capital public et celle de la productivite totale des facteurs (PTF) evoluent de la meme facon et soutenons que les estimations de l'effet du capital public fondees sur la fonction de production surestiment par consequent cet effet, parce qu'elles englobent une partie de ce qui est inclus dans les estimations de la PTF. Nous montrons aussi que la similarite entre la croissance du capital public et celle de la PTF donne lieu a un grand intervalle de confiance autour des estimations de l'elasticite du capital public produites d'apres le cadre de la fonction de production. Par la suite nous calculons un intervalle de confiance d'apres la fonction de production d'abord estimee en tenant compte de la croissance de la PTF, puis en n'en tenant pas compte. Ensuite, nous utilisons une fonction de cout pour obtenir des estimations plus precises de la reduction des couts marginaux attribuable au capital public. Fait important, l'estimation calculee d'apres la fonction de cout se situe dans la partie inferieure de l'intervalle de confiance etabli d'apres la fonction de production. Nous montrons alors que le taux de rendement associe aux estimations chevauchantes couvre un intervalle qui s'etend du taux moyen des obligations d'Etat a long terme au taux de rendement du capital prive.
A Wireless Traffic Surveillance System Using Video Analytics

Video surveillance systems have been commonly used in transportation systems to support traffic monitoring, speed estimation, and incident detection. However, there are several challenges in developing and deploying such systems, including high development and maintenance costs, bandwidth bottleneck for long range link, and lack of advanced analytics. In this thesis, I leverage current wireless, video camera, and analytics technologies, and present a wireless traffic monitoring system. I first present an overview of the system. Then I describe the site investigation and several test links with different hardware/software configurations to demonstrate the effectiveness of the system. The system development process was documented to provide guidelines for future development. Furthermore, I propose a novel speed-estimation analytics algorithm that takes into consideration roads with slope angles. I prove the correctness of the algorithm theoretically, and validate the effectiveness of the algorithm experimentally. The experimental results on both synthetic and real dataset show that the algorithm is more accurate than the baseline algorithm 80% of the time. On average the accuracy improvement of speed estimation is over 3.7% even for very small slope angles.
Parameterized Local Reduction of Decision Systems

One important and valuable topic in rough sets is attribute reduction of a decision system. The existing attribute reductions are designed to just keep confidence of every certain rule as they cannot identify key conditional attributes explicitly for special decision rules. In this paper, we develop the concept of -local reduction in order to offer a minimal description for special -possible decision rules. The approach of discernibility matrix is employed to investigate the structure of a -local reduction and compute all -local reductions. An example of medical diagnosis is employed to illustrate our idea of the -local reduction. Finally, numerical experiments are performed to show that our method proposed in this paper is feasible and valid.
The clinical importance of rhinovirus-associated early wheezing

To the Editors: In a recent report by a European Respiratory Society Task Force 1, human rhinovirus (HRV)-associated bronchiolitis and wheezing illness were not sufficiently discussed. Several recent observations highlight the importance of HRV infections in young wheezing children. First, HRV is commonly associated with bronchiolitis and early-life wheezing, second only to respiratory syncytial virus (RSV). Detection rates have reached 40% in hospitalised wheezing infants 2, 3. Moreover, HRV infection has been associated with the severity of illness 4. Secondly, HRV infection among early wheezers is an important independent risk factor for recurrent wheezing 2, 5–8. In population-based studies on young hospitalised children with acute wheezing, HRV infection has been associated with recurrent wheezing (≥3 physician-confirmed episodes) during a 12-month follow-up period …
Power converters with Silicon Carbide devices

The paper discusses power electronic converters built with the use of new Silicon Carbide power devices: diodes and transistors. At first a discussion of SiC material properties is presented as a background to overview of currently available power transistors. Then, parameters of the devices are discussed with respect to Si counterparts and design possibilities are analyzed using example of a three-phase AC/DC converter with SiC MOSFETs. Moreover, various prototypes of the power converters are shown in this paper to illustrate high-frequency and high-efficiency designs. Presented examples reach frequencies of hundreds kHz to reduce passive components but a three-phase inverter with efficiency above 99.5% is also shown. Finally, the interleaved DC/DC boost converter having high efficiency (close to 99%) at high switching frequency (4×125kHz) is discussed in this paper.
CD28 and Lipid Rafts Coordinate Recruitment of Lck to the Immunological Synapse of Human T Lymphocytes1

In T lymphocytes, the Src family kinase Lck associates lipid rafts and accumulates at the immunological synapse (IS) during T cell stimulation by APCs. Using CD4- or CD28-deficient murine T cells, it was suggested that recruitment of Lck to the IS depends on CD4, whereas CD28 sustains Lck activation. However, in human resting T cells, CD28 is responsible for promoting recruitment of lipid rafts to the IS by an unknown mechanism. Thus, we performed a series of experiments to determine 1) whether Lck is recruited to the IS through lipid rafts; and 2) whether Lck recruitment to the IS of human resting T cells depends on CD4 or on CD28 engagement. We found that CD28, but not CD4, stimulation induced recruitment of Lck into detergent-resistant domains as well as its accumulation at the IS. We also found that Lck recruitment to the IS depends on the CD28 COOH-terminal PxxPP motif. Thus, the CD28-3A mutant, generated by substituting the prolines in positions 208, 211, and 212 with alanines, failed to induce Lck and lipid raft accumulation at the synapse. These results indicate that CD28 signaling orchestrates both Lck and lipid raft recruitment to the IS to amplify T cell activation.
Zeitgenössische Dokumentarliteratur (“literatura testimonial”) in Zentralamerika. Formen, Themen und Funktionen

Im Jahre 1978 publizierte der kolumbianische Literaturwissenschaftler Carlos Rincon eine beachtenswerte Studie über den gegenwärtigen Wandel des Literaturbegriffs in Lateinamerika. Dieser Wandel . lasse sich freilich so der Autor auf der Basis der herrschenden ästhetischen Theorien und der ihnen entsprechenden Methoden weder erklären noch beschreiben. Dies gelte für die Nachfahren der idealistisch-hegelianischen Tradition ebenso wie für die Repräsentanten formalistisch-strukturalistischer und semiotisch-kommunikationstheoretischer Ansätze. Nur eine Theorie, die in der Lage sei, den Prozeß von Produktion und Rezeption als eine ästhetische Form gesellschaftlicher Praxis ("forma estetica de praxis social") zu verstehen, könne sich als fähig erweisen, die historischen Veränderungen, denen der Literaturbegriff gegenwärtig in Lateinamerika unterworfen sei, zu begreifen und zu analysieren. Was jedoch in der Theorie und der Methodologie noch kaum einen Niederschlag gefunden habe, sei in der literarischen Praxis schon weithin erkennbar, in der Romanproduktion ebenso wie im Bereich des "cuento" und vor allem in der sich entwickelnden neuen Gattung der Dokumentarliteratur. Gemeinsames Merkmal all dieser Phänomene sei die Tendenz, traditionell für unüberwindbar gehaltene Oppositionen wie fiktional/nicht-fiktional, autonom/heteronom außer Kraft zu setzen, "pues realidad y ficcion no estän en una relacion de polaridad ontologica, sino que la ficcion organiza la realidad vivida para hacernosla comunicable". Als Ursache solchen Wandels im Literaturbegriff sah der Autor die veränderte politische und gesellschaftliche
Effects of postnatal depression on children's adjustment to school

Background Little is known of the behavioural adjustment of children of postnatally depressed mothers. Previous studies have relied on maternal reports, and have produced inconsistent findings. Method In a prospective, longitudinal study of the five-year-old children of a community sample of postnatally depressed and well women, evidence was collected concerning the children's adjustment in the context of school, teachers being asked to complete questionnaires after the children had finished their first term. Results Family social class and the child's gender had the most pervasive influences on adjustment. However, both postnatal and recent maternal depression were associated with significantly raised levels of child disturbance, particularly among boys and those from lower social class families. Conclusions The findings indicate a persistent effect of postnatal depression on child adjustment. They highlight the need for resources devoted to supporting mothers of young children and particularly routine screening and treatment for postnatal mood disorder.
Étude des traits d'histoire de vie de "Melampsora larici-populina", agent de la rouille du peuplier : de leur déterminisme génétique à leurs conséquences évolutives

L’adaptation d’un champignon pathogene a son milieu, ainsi que l’evolution et la structuration des populations qui en decoulent, sont fortement influences par ses traits d’histoire de vie qui conditionnent sa fitness. C’est ce que nous avons illustre chez Melampsora larici-populina, l’agent de la rouille du peuplier. Ainsi, nous avons mis en evidence que le volume des spores du champignon evolue de maniere repetable au cours des epidemies annuelles dans la vallee de la Durance, et ce sous l’effet de la selection naturelle, signe que ce trait intervient directement dans le processus adaptatif du champignon. Par consequent, les contraintes genetiques conditionnant le potentiel adaptatif du champignon en lien avec les traits d’histoire de vie ont ete etudiees en laboratoire, au sein d’une descendance S1 issue de l’autofecondation d’une souche de reference. Les resultats obtenus suggerent que M. larici-populina presente un potentiel adaptatif eleve. Enfin, une carte genetique a haute resolution du champignon, comprenant 18 chromosomes, a ete construite afin d’etudier le determinisme genetique de ces traits d'histoire de vie. Un locus de virulence ainsi que des QTL intervenant dans l’expression de la taille des lesions ont pu etre detectes et positionnes avec precision sur cette carte. Ce travail a mis en evidence le role des traits quantitatifs dans l’adaptation et la structuration des populations de M. larici-populina en reponse aux pressions de selection du milieu, en lui conferant un potentiel adaptatif elevee, essence de l’adaptation des organismes. Il ouvre egalement de nombreuses perspectives de recherche visant a identifier les bases genetiques de l’adaptation de ce champignon pathogene a son hote, elements indispensables a l’elaboration de strategies de lutte durables
