Research on the cognitive consequences of bilingualism suggests a bilingual advantage: early experience with more than one language predicts better inhibitory control of attention. The mechanisms responsible for this advantage, however, are not well understood. We ask whether depth and time-course of memory encoding may be responsible. We measured bilingual and monolingual adults’ memory for no...

Spatial variability in a flow field leads to spreading of a tracer plume. The effect of microdispersion is to smooth concentration gradients that exist in the system. The combined effect of these two phenomena leads to an 'effective' enhanced mixing that can be asymptotically quantified by an effective dispersion coefficient (i.e. Taylor dispersion). Mixing plays a fundamental role in driving c...

This investigation examines published results of traditional diffusion experiments on ovalbumin and bovine serum albumin to determine the extent to which assumed concentration independence of the translational diffusion coefficient is a reasonable approximation in the analysis of boundary spreading in sedimentation velocity experiments on proteins. Although significant positive concentration de...

Ninety-two rice (Oryza sativa L.) genotypes were evaluated during kharif 2013 to estimate the genetic variability, heritability and correlation coefficients for 14 physicochemical and cooking quality traits. The experiment was conducted in a complete randomized block design with 3 replications. Highly significant (P < 0.01) differences were observed for all 14 quality characters studied. Among ...

The problem of deciding what is implied by a written text. of “reading between the lines” is the problem of text Inference. To extract proper inferences from a text requires a great deal of generol knowledge on the port of the reader. Past approaches have often used a “strong method” tuned to process a particular kind of knowledge structure (such OS a script, or a plan). The alternative is a “w...

Autoimmune diseases are typically characterized by a persistent inflammatory self-recognition process that ultimately leads to chronic progressive disability. Over the past several years we have addressed the fundamental question of why autoimmune diseases are chronic. Our working hypothesis in these studies has been that autoimmunity involves a continuous acquisition of new self-recognition ev...

The social aspects of the group members are usually omitted in today’s group recommenders. In this paper we propose novel approach for the intergroup processes modeling, while the friendship type, user’s personality and the group context is considered in order to reflect the group member influence. Moreover, the bi-directional emotional contagion is reflected by the spreading activation over th...
