Weak amenability of weighted Orlicz algebras

Let G be a locally compact abelian group, $\omega:G\to (0,\infty)$ be a weight, and ($\Phi$,$\Psi$) be a complementary pair of strictly increasing continuous Young functions. We show that for the weighted Orlicz algebra $L^\Phi_\omega(G)$, the weak amenability is obtained under conditions similar to the one considered by Y. Zhang for weighted group algebras. Our methods can be applied to various families of weighted Orlicz algebras, including weighted $L^p$-spaces

Measurable entanglement

Amount of entanglement carried by a quantum bipartite state is usually evaluated in terms of concurrence (see Ref. 1). We give a physical interpretation of concurrence that reveals a way of its direct measurement and discuss possible generalizations.Comment: 3 pages, submitted to Applied Physics Letter

Quantification of entanglement via uncertainties

We show that entanglement of pure multi-party states can be quantified by means of quantum uncertainties of certain basic observables through the use of measure that has been initially proposed in [10] for bipartite systems.Comment: Changed content, references added 7 pages, no figures, PRA in pres

Chaotic translations on weighted Orlicz spaces

Let $G$ be a locally compact group, $w$ be a weight on $G$ and $\Phi$ be a Young function. We give some characterizations for translation operators to be topologically transitive and chaotic on the weighted Orlicz space $L_w^\Phi(G)$. In particular, transitivity is equivalent to the blow-up/collapse property in our case. Moreover, the dense set of periodic elements implies transitivity automatically

DOES THE DIGITAL GENERATION COMPREHEND BETTER FROM THE SCREEN OR FROM THE PAPER?: A META-ANALYSIS

This research was carried out to determine whether the comprehension level differs according to the reading environment by examining the studies comparing the comprehension level according to reading from the screen and from the paper by using meta-analysis method. Meta-analysis method was used in this research. The data of the study were obtained from 12 studies (29 comparisons). All of these studies are studies in which Turkish texts are used in reading. The analysis of the obtained data was carried out using the Comprehensive MetaAnalysis software. In the interpretation of the studies, random effects model was taken as basis. As a result of the analyses performed, a significant and medium effect size (g=-0.423, p=0.003) was found in favor of reading from the paper. Therefore, this result shows that comprehension achievement is higher in reading from the paper than reading from the screen. In addition, it was determined that the effect sizes did not differ significantly according to the publication year, grade level, text type and digital tool. It is recommended to perform studies on improving the screen interface and screen reading skills

Hibernasyondaki Anadolu yer sincabı (spermophilus xanthoprymnus) gastrointestinal kanalında galektin-1 ve galektin-3'ün ekspresyon paternleri

Hibernation is a survival adaptation characterized by extended fasting when food is less or unavailable. Prolonged fast may affects various proteins expression including galectins binding β-galactosyl. There is no data on the expression of Galectin-1 and -3 (Gal-1 and -3) during hibernation. This study aimed to examine the expression of Gal-1 and -3 in hibernating Anatolian ground squirrel (Spermophilus xanthoprymnus) gastrointestinal tract. Intense Gal-1 immunostaining was observed in some cells of both gastric lamina propria and villous connective tissue of the small intestine. In colon and cecum, intense Gal-1 immunoreaction was observed in some connective tissue cells around the crypt epithelium, as well as in the smooth muscles of vessel walls, lamina muscularis and tunica muscularis of all the regions. Gastric foveolar epithelium showed moderate nuclear and intracytoplasmic Gal-3 immunostaining. Moreover, Gal-3 immunostaining was detected in villous epithelial cells of the duodenum and ileum. Intense Gal-3 labeling also was present in all the cryptal surface epithelial cells of the colon and cecum. In conclusion, both Gal-1and Gal-3 expression in gastrointestinal tract during hibernation was similar to that of non-hibernating species. In the gastrointestinal tract, Gal-1 did not display different expression pattern, whereas Gal-3 expression was more intense in large intestine epithelium.Hibernasyon, besinin az olduğu veya hiç olmadığı uzun süreli açlık ile karakterize olan durumlarda hayatta kalma adaptasyonudur. Uzun süreli açlık β-galaktozil bağlayan galektinler de dahil olmak üzere bir çok proteinin ekspresyonunu etkileyebilir. Galektinler, β-galaktozil bağlayan proteinlerdir. Hibernasyonda Galektin-1 ve -3 (Gal1 ve-3)’ün ekspresyonuna ilişkin herhangi bir veri bulunmamaktadır. Bu çalışmada hibernasyondaki Anadolu yer sincabı (Spermophilus xanthoprymnus) gastrointestinal kanalında Gal-1 ve 3’ün ekspresyonunun incelenmesi amaçlanmıştır. Hem gastrik lamina propria hem de ince bağırsağın villöz bağ dokusundaki bazı hücrelerde yoğun Gal-1 immün boyanması gözlendi. Gastrointestinal kanalın bütün bölümlerindeki damar duvarları, lamina muskularis ve tunika muskularisindeki düz kaslarda yoğun Gal-1 ekspresyonu gözlendi. Ayrıca kolon ve sekumda kript epiteli etrafındaki bazı bağ dokusu hücrelerinde de yoğun Gal-1 immünoreaksiyonu belirlendi. Gastrik foveoler epitel hücreleri orta derecede nükleer ve intrasitoplazmik Gal-3 immun reaksiyon gösterdi. Duodenum ve ileumun villöz epitel hücrelerinde Gal-3 immün boyaması tespit edildi. Ayrıca, kolon ve sekumdaki kriptlerin yüzey epitel hücrelerinde yoğun Gal-3 boyanması görüldü. Sonuç olarak hibernasyon sürecinde gastrointestinal kanaldaki hem Gal-1 hem de Gal-3 ekspresyonu hibernasyona yatmayan türlerle benzerdi. Gastrointestinal kanal bölümlerinde Gal-1 ekspresyonu açısından farklılık gözlenmezken, Gal-3 ekspresyonu diğer gastrointestinal bölümlere nazaran kalın bağısak epitelinde daha yoğundu

Effects of Joule Heating on Magnetic Field Inside a Channel Along with a Cavity

AbstractA computational solution has been made to obtain flow and temperature field inside a channel with a cavity under magnetic field and joule effect. The left side of the cavity is shorter than right side. Mixed convection heat transfer is studied. Finite element method is used to solve governing equations of laminar flow. The study investigates the effects of three parameters such as Hartmann number, joule parameter and Prandtl numbers for pure mixed convection (Ri = 1). For the specified conditions streamline contours and isotherm contours are obtained and later on the variation of overall Nusselt number and exit temperature are obtained for the aforementioned parameters. It is found that the aforesaid parameters are extremely effective parameter on flow field and temperature distribution. It is also found that both Hartmann number and joule parameter play important role to control the mode of heat transfer
