Designing Publicly Engaged First-Year Research Projects: Protest Art and Social Change

open access: yesPrompt, 2021
This research assignment invites students in a first-year writing preparation course to explore topics of social justice through protest art. The course is taught at a small, private liberal arts college in a course for “emerging writers.” I have taught ...

Task assignment in tree-like hierarchical structures [PDF]

open access: yesJournal of Combinatorial Optimization, 2016
Most large organizations, such as corporations, are hierarchical organizations. In hierarchical organizations each entity in the organization, except the root entity, is a sub-part of another entity. In this paper we study the task assignment problem to the entities of tree-like hierarchical organizations.

Proton-Electron Hyperfine Coupling Constants of the Chlorophyll a Cation Radical by ENDOR Spectroscopy [PDF]

open access: yes, 1977
In this paper we describe the assignment of the major coupling constants in monomer chlorophyll a cation free radical by ENDOR spectroscopy. To facilitate chemical manipulation methylpyrochlorophyllide a has been used as a stand-in, and a suite of six ...

Maximizing System Throughput Using Cooperative Sensing in Multi-Channel Cognitive Radio Networks [PDF]

open access: yes, 2012
In Cognitive Radio Networks (CRNs), unlicensed users are allowed to access the licensed spectrum when it is not currently being used by primary users (PUs). In this paper, we study the throughput maximization problem for a multi-channel CRN where each SU

DSSPcont: continuous secondary structure assignments for proteins [PDF]

open access: yesNucleic Acids Research, 2003
The DSSP program automatically assigns the secondary structure for each residue from the three-dimensional co-ordinates of a protein structure to one of eight states. However, discrete assignments are incomplete in that they cannot capture the continuum of thermal fluctuations.

Spectrally-resolved femtosecond reflectivity relaxation dynamics in undoped SDW 122-structure iron based pnictides

open access: yes, 2014
We systematically investigate temperature- and spectrally-dependent optical reflectivity dynamics in AAs$_{2}$Fe$_{2}$, (A=Ba, Sr and Eu), iron-based superconductors parent spin-density-wave (SDW) compounds.

NMR Data Analysis of Acarbose

open access: yesChinese Journal of Magnetic Resonance
Acarbose, an α-glucosidase inhibitor, has been widely used in the treatment of type-II diabetes due to its unique mechanism of action. In this study, comprehensive and accurate 1H and 13C NMR data of acarbose in DMSO-d6, including 1H NMR data of all ...

Learning to Divide and Conquer for Online Multi-Target Tracking [PDF]

open access: yes, 2015
Online Multiple Target Tracking (MTT) is often addressed within the tracking-by-detection paradigm. Detections are previously extracted independently in each frame and then objects trajectories are built by maximizing specifically designed coherence ...
