We present here the recent developments in the studies of self-organization in abiotic, biotic (bacterial) colonies and man-made (programmable chips) systems, aimed at seeking to unravel the general principles of biotic self-organization. A typical bacterial colony consists of 10 − 10 bacteria. It is not created by pre-design or according to a plan, but through a process of biotic self-organiza...

We show the first non-trivial positive algorithmic results (i.e. programs whose output is larger than their size), in a model of self-assembly that has so far resisted many attempts of formal analysis or programming: the planar non-cooperative variant of Winfree’s abstract Tile Assembly Model. This model has been the center of several open problems and conjectures in the last fifteen years, and...

The expression of self-antigen in the thymus is believed to be responsible for the deletion of autoreactive T lymphocytes, a critical process in the maintenance of unresponsiveness to self. The Autoimmune regulator (Aire) gene, which is defective in the disorder autoimmune polyglandular syndrome type 1, has been shown to promote the thymic expression of self-antigens. A clear link, however, bet...

background human preimplantation embryonic cells share many similarities with cancer cells such as ability to self-renew, unlimited proliferation and maintenance of the undifferentiated state. embryo-cancer sequence a (ecsa), also known as developmental pluripotency associated-2 (dppa2), is a cancer testis antigen (cta) with unclear biological function yet. objective: ctas are expressed normall...

Autistic children face significant barriers to having their views listened in research. Inaccessible research encounters and inflexible communication strategies on the part of a team can prevent opportunities for engage meaningfully Researchers must strive offer meaningful self-expression, improve way they seek autistic children’s points view. This article explores ways with, listen to, school-...

[Purpose] This study investigates the effects of task-oriented activities on hand function, cognitive function, and self-expression of the elderly with dementia, and then identify the influencing factors on self-expression in sub-factors of dependent variables. [Subjects and Methods] Forty elderly persons were divided into two groups: intervention group (n=20) and control group (n=20). The inte...
