سیستمهای الکترونی همبسته قوی در شبکههای ناکام
We give an overview of recent work on charge degrees of freedom of strongly correlated electrons on geometrically frustrated lattices. Special attention is paid to the checkerboard lattice, i.e., the two-dimensional version of a pyrochlore lattice and to the kagomé lattice. For the checkerboard lattice it is shown that at half filling when spin degrees of freedom are neglected and at quarter f...
متن کامل“Something You Do with Your Body”: The Experience and Meaning of Physical Activity from the Perspective of Transnational Youth
Background. The transnational young people’s physical activity participation could intermingle with their ingrained dispositions acquired from their pre-migrating periods, experiences of transnational mobility, new cultural learning, and other migration processes. Objectives. The current study aimed to investigate transnational youth’s physical activity experience using photo-elicitation inte...
متن کاملExplaining the Concept and Models of Serendipity In Information Search Process
Background and Aim: Searching for information is not always a targeted activity; it can also be done involuntarily. The serendipity has the ability to find information randomly and as something happy, something unexpected, or a pleasant surprise. This paper examines and analyzes the concept of serendipity and its models in the process of information searching. Methods: The present study uses a ...
متن کاملP 98: Neuroinflammation and Nanomedicine,How about Cerebral Palsy
Cerebral palsy (CP) is the most common motor disability in children, usually occurring during fetal development; before, during, or shortly after birth, or during infancy. CP takes place in about 2.1 per 1,000 live births .There is no exact reason but birth injury or inflammation of the central nervous system, infections and hypoxia are related risk factors of this disease. Often, symptoms incl...
متن کاملNew Integrable Version of the Degenerate Supersymmetric T-j Model
A new integrable version of the degenerate supersymmetric t-J model is proposed. In this formulation instead of restricting single occupancy of electrons at each lattice site we may have up to two electrons at each site. As a requirement of exact integrability the hopping interaction turns out to be correlated with the density of electrons in the neighboring sites. The exact solution of the mod...
