Numerical modeling of DNA-chip hybridization with chaotic advection     

Florence Raynal  Aurélien Beuf  Philippe Carrière 《Biomicrofluidics》2013,7(3)

We present numerical simulations of DNA-chip hybridization, both in the “static” and “dynamical” cases. In the static case, transport of free targets is limited by molecular diffusion; in the dynamical case, an efficient mixing is achieved by chaotic advection, with a periodic protocol using pumps in a rectangular chamber. This protocol has been shown to achieve rapid and homogeneous mixing. We suppose in our model that all free targets are identical; the chip has different spots on which the probes are fixed, also all identical, and complementary to the targets. The reaction model is an infinite sink potential of width d_h, i.e., a target is captured as soon as it comes close enough to a probe, at a distance lower than d_h. Our results prove that mixing with chaotic advection enables much more rapid hybridization than the static case. We show and explain why the potential width d_h does not play an important role in the final results, and we discuss the role of molecular diffusion. We also recover realistic reaction rates in the static case.  相似文献   

On passion and sports fans: A look at football

Abstract

The purpose of the present research was to test the applicability of the Dualistic Model of Passion (Vallerand et al., 2003 Vallerand, R. J., Blanchard, C. M., Mageau, G. A., Koestner, R., Ratelle, C.Léonard, M. 2003. Les passions de l'âme: On obsessive and harmonious passion. Journal of Personality and Social Psychology, 85: 756–767. [Crossref], [PubMed], [Web of Science ®] , [Google Scholar]) to being a sport (football) fan. Three studies provided support for this dualistic conceptualization of passion. Study 1 showed that harmonious passion was positively associated with adaptive behaviours (e.g. celebrate the team's victory), whereas obsessive passion was positively associated with maladaptive behaviours (e.g. risking losing one's job to go to a game). Study 2 used a short Passion Scale and showed that harmonious passion was positively related to the positive affective life of fans during the 2006 FIFA World Cup, psychological health (self-esteem and life satisfaction), and public displays of adaptive behaviours (e.g. celebrate the team's victory into the streets), whereas obsessive passion was predictive of maladaptive affective life (e.g. hating opposing teams' fans) and behaviours (e.g. mocking opposing teams' fans). Finally, Study 3 examined the role of obsessive passion as a predictor of partner's conflict that in turn undermined partner's relationship satisfaction. Overall, the present results provided support for the Dualistic Model of Passion. The conceptual and applied implications of the findings are discussed.  相似文献   

Changes in swimming technique during time to exhaustion at freely chosen and controlled stroke rates

Abstract

The aim of this study was to assess technical changes during constrained swimming in time-to-exhaustion tests. Ten swimmers of national standard performed a maximal 400-m front crawl and two sets of exhaustion tests at 95%, 100%, and 110% of mean 400-m speed. In the first set (free), swimmers had to maintain their speeds until exhaustion and mean stroke rate was recorded for each test. In the second set (controlled), the same speed and individual corresponding stroke rate were imposed. The durations of the exhaustion tests, relative durations of the stroke phases, and arm coordination were analysed. For each speed in the “controlled” set, the exhaustion tests were shorter. Moreover, variables were consistent, suggesting a stabilization of stroke technique. Under the free condition, stroke rate increased to compensate for the decrease in stroke length. At the same time, swimmers reduced the relative duration of their non-propulsive phases in favour of the propulsive phases. Thus, swimmers changed their arm coordination, which came close to an opposition mode. These two constraints enable swimmers both to maintain their stroking characteristics and develop compensatory mechanisms to maintain speed. Moreover, stroke rate can be seen as a useful tool for controlling arm technique during paced exercise.  相似文献   

Effectiveness of a heritage educational program for the acquisition of oral and written French and Tahitian in French Polynesia     

Isabelle Nocus  Philippe Guimard 《Teaching and Teacher Education》2012,28(1):21-31

The research examines the effects of a bilingual pedagogical program (French/Tahitian) on the acquisition of oral and written French as well as the Tahitian language itself in primary schools in French Polynesia. 125 children divided into an experimental group (partially schooled in Tahitian for 300 min per week) and a control group (schooled in French) were followed from the second year of kindergarten to Grade 1 and tested on Tahitian and French language competence. The results show that the program appears to have a positive impact on Tahitian proficiency, without any negative effect on learning of French (oral and reading).  相似文献
