Identifying Food Insecurity and Increasing Access to Nutrition in Brandon, VT
Food insecurity is a significant problem in Vermont affecting over 10% of the population in 2016. Access to nutrition is an important social determinant of health with long term implications for our communities. In order to increase awareness of existing infrastructure to reduce food insecurity in Rutland County, a resource guide was created with information about local food pantries, community dinners, and assistance obtaining 3SquaresVT benefits.https://scholarworks.uvm.edu/fmclerk/1394/thumbnail.jp
Pliable Polaritons: Wannier Exciton Plasmon Coupling in Metal Semiconductor Structures
Plasmonic structures are known to support the modes with subwavelength
volumes in which the field matter interactions are greatly enhanced. Coupling
between the molecular excitations and plasmons leading to formation of
plexcitons has been investigated for a number of organic molecules. However,
plasmon-exciton coupling in metal semiconductor structures have not experienced
the same degree of attention. In this work we show that the very strong
coupling regime in which the Rabi energy exceeds the exciton binding energy is
attainable in semiconductor cladded plasmonic nanoparticles and leads to
formation of Wannier Exciton Plasmon Polariton (WEPP) that is bound to the
metal nanoparticle and characterized by dramatically smaller (by factor of few)
excitonic radius and correspondingly higher ionization energy. This higher
ionization energy exceeding approaching 100meV for the CdS/Ag structures may
make room temperature Bose Einstein condensation and polariton lasing in
plasmonic/semiconductor structures possibl
Pure infiniteness, stability and C*-algebras of graphs and dynamical systems
Pure infiniteness (in sense of E.Kirchberg and M.R{\o}rdam) is considered for
C*-algebras arising from singly generated dynamical systems. In particular,
Cuntz-Krieger algebras and their generalizations, i.e., graph-algebras and O_A
of an infinite matrix A, admit characterizations of pure infiniteness. As a
consequence, these generalized Cuntz-Krieger algebras are traceless if and only
if they are purely infinite. Also, a characterization of AF-algebras among
these C*-algebras is given. In the case of graph-algebras of locally finite
graphs, characterizations of stability are obtained.Comment: 31 page
