Vapor-Deposited Glasses with Long-Range Columnar Liquid Crystalline Order
(American Chemical Society, 2017-10-04)Anisotropic molecular packing, particularly in highly ordered liquid crystalline arrangements, has the potential for optimizing performance in organic electronic and optoelectronic applications. Here we show that physical ... -
Vapor-deposited Organic Glasses Exhibit Enhanced Stability Against Photodegradation
(Soft Matter, 2018-03-25)Photochemically stable solids are in demand for applications in organic electronics. Previous work has established the importance of the molecular packing environment by demonstrating that different crystal polymorphs ... -
Variability in Ostariophysan Fish Brain Anatomy in Relation to the Neural Pathway of Innate Fear Response
(2015-04)Our research has focused on Zebrafish (Danio rerio) and Creek Chub (Semotilus atromaculatus), two species which have distinguished applications in the inquiry of the alarm response. While Zebrafish are easily bred have a ... -
Variability in Ostariophysan Fish Brain Anatomy in Relation to the Neural Pathway of Innate Fear Response
(2014-04)Upon exposure to odorant molecules, such as alarm substance, fish exhibit a distinct behavioral response as a result of the neural pathway that is activated by the chemical ligand. Various hypotheses have been developed ... -
Variability in Use of Dasiphora Fruticosa (L.) Rydb. as a Nectar Plant by Butterflies : Latitudinal Differences in the Rocky Mountains
(2015-04)In 2004, our lab In 2004, our lab verified that D. fruticosa was an important nectar resource for adult butterflies in the southern Rockies (Jemez Mountains, New Mexico) yet little is known if this is true for more northern ... -
The Variability of Urbanization in Lower Silesian Voivodeship, Poland
(2012)Most research studies examining Polish urban patterns at the national scale consider only one approach to quantify changes in the urbanization levels: measurement based on demographic data or measurement based on land-cover. ... -
Variable Selection or Variable Assessment?
(1995-02)Variable-selection regression methods are oriented towards selecting a single model as the vehicle for further inferences. The appropriate inference about variables not included is unclear - the conclusion that they have ... -
A Variable-Complexity Norm Maximization Problem
(University of Wisconsin-Madison Department of Computer Sciences, 1984) -
A variable-penalty alternating directions method for convex optimization
(1995)We study a generalized version of the method of alternating directions as applied to the minimization of the sum of two convex functions subject to linear constraints. The method consists of solving consecutively in each ... -
Variation in gill rakers of asian carp and native filter-feeding fishes from the Illinois, James and Wabash Rivers, USA
(2012-12)Populations of silver (Hypophthalmichthys molitrix) and bighead carp (H. nobilis) may be controlled by targeting the structure of gill rakers - how they filter food particles from the water column. Because species-specific ... -
Variation in Soil Properties and Topographic Roughness of Stabilized Sand Dunes in the Central Great Plains, USA: Implications for Susceptibility to Reactivation
(2018-12)With a warming global climate, regional climates will undergo changes to their temperature, precipitation, and wind regimes. Consequently, the potential exists for these shifting climatological conditions to affect dunefields ... -
VARIATION OF ACUTE TOXICITY WITH WATER SOURCE
(1983)Physical and chemical characteristics of water may affect the biological avail ability and toxicity of chemicals in aquatic environments. Hardness, alkalinity, pH, dissolved organic matter, and suspended materials ...
