The slow β relaxation is understood to be a universal feature of glassy dynamics. Its presence in bulk metallic
glasses (BMGs) is evidence of a broad relaxation time spectrum that extends to deep within the glassy state.
Despite the breadth of research devoted to this phenomenon, its microscopic origin is...
We report vibrational information of both the first electronically excited state and the ground
cationic state of jet-cooled triphenylene via the techniques of resonantly enhanced multiphoton
ionization (REMPI) and zero kinetic energy (ZEKE) photoelectron spectroscopy. The first excited
electronic state S₁ of the neutral molecule is of A₁' symmetry and...
The zebrafish (Danio rerio) is emerging as a new important species for studying brain mechanisms and its deficits. Focusing on selected CNS disorders (brain cancer, epilepsy and anxiety) and using them as examples, we discuss the value of zebrafish models in translational neuroscience, and their contribution to neuroimaging, circuit-level and...
We studied the reliability and validity of the Columbia Suicide Severity Scale (C-SSRS).
Severely delinquent adolescent girls (n = 166) participated in a treatment trial and repeated
assessments over time. Lifetime suicide attempt history was measured using the C-SSRS in early
adulthood (n = 144; 7–12 years post-baseline). Nonclinician raters...
How do you test a program when only a single user, with no expertise in software testing, is able to determine if the
program is performing correctly? Such programs are common today in the form of machine-learned classifiers. We consider the
problem of testing this common kind of machine-generated program...
The protein palmitoylation cycle has been shown to be important for protein signaling and synaptic plasticity. Data from our lab showed a change in the palmitoylation status of certain proteins with age. A greater percentage of the NMDA receptor subunits GluN2A and GluN2B, along with Fyn and PSD95 proteins, were...
A novel patterning technique that creates magnetization patterns in a continuous magnetostrictive
film with surface acoustic waves is demonstrated. Patterns of 10 μm wide stripes of alternating
magnetization and a 3 μm dot of reversed magnetization are written using standing and focusing
acoustic waves, respectively. The magnetization pattern is size-tunable,...
BACKGROUND: Workers onboard freezer-trawl (FT) and freezer-longline (FL) vessels in Alaska may be at high risk for fatal and non-fatal injuries. METHODS: Traumatic occupational injuries onboard vessels in the FT and FL fleets were identified through two government data sources. RESULTS: The annual risk of fatal injuries was 125 per...
A compact, low-cost, wireless gamma-ray spectrometer is a tool sought by a number of different organizations in the field of radiation detection. Such a device has applications in emergency response, battlefield assessment, and personal dosimetry. A prototype device fitting this description has been constructed in the Advanced Radiation Instrumentation Laboratory...
This study examines the willingness of canoe owners and crew members to participate in an insurance scheme in Ghana. A total of 386 canoe owners and 164 crew from four (4) coastal regions and the inland lake areas were sampled. Data was collected through semi-structured questionnaires on socio-economic characteristics, canoe...
