Unfolding Rates for the Diffusion-Collision Model
In the diffusion-collision model, the unfolding rates are given by the
likelihood of secondary structural cluster dissociation. In this work, we
introduce an unfolding rate calculation for proteins whose secondary structural
elements are -helices, modeled from thermal escape over a barrier which
arises from the free energy in buried hydrophobic residues. Our results are in
good agreement with currently accepted values for the attempt rate.Comment: Shorter version of cond-mat/0011024 accepted for publication in PR
Moduli spaces of coherent systems of small slope on algebraic curves
Let be an algebraic curve of genus . A coherent system on
consists of a pair , where is an algebraic vector bundle over of
rank and degree and is a subspace of dimension of the space of
sections of . The stability of the coherent system depends on a parameter
. We study the geometry of the moduli space of coherent systems for
. We show that these spaces are irreducible whenever they are
non-empty and obtain necessary and sufficient conditions for non-emptiness.Comment: 27 pages; minor presentational changes and typographical correction
The effect of a writing course on the English language arts state assessment examination in a South Texas high school
The purpose of this study is to analyze the impact a writing course will have on test scores for At-Risk students who are taking the English I and/or English II State of Texas Assessment of Academic Readiness End-of-Course exam. The group analyzed was comprised of 2nd and 3rd year cohort students
Fill Your Gaps of the Spectrum
Fill Your Gaps of the Spectrum presents the responsibilities of an intern from the Pediatric Developmental Center (PDC), as well as the mission that the center works towards accomplishing for the community. The current intern responsibilities range, depending on their availability, and allow for different learning opportunities as the PDC offers an array of services for children and families with special needs. The PDC reaches many families in the Chicago area, as centers like such are in high demand. As an intern, Yesenia is developing a podcast to support English and Spanish speaking families with a diagnosis of autism
Size effects in multiferroic BiFeO3 nanodots: A first-principles-based study
An effective Hamiltonian scheme is developed to investigate structural and
magnetic properties of BiFeO3 nanodots under short-circuit-like electrical
boundary conditions. Various striking effects are discovered. Examples include
(a) scaling laws involving the inverse of the dots' size for the magnetic and
electric transition temperatures; (b) the washing out of some structural phases
present in the bulk via size effects; (c) the possibility of tailoring the
difference between the Neel and Curie temperatures, by playing with the size
and electrical boundary conditions; and (d) an universal critical thickness of
the order of 1.6 nm below which the dots do not possess any long-range ordering
for the electrical and magnetic dipoles, as well as, for the oxygen octahedral
tiltings.Comment: 3 figure
