151 Meadows, NatalieHunting for insight: an analysis of hunting behaviors in miceBehaviors revolving around the acquisition of food resources are complex and crucial processes for many organisms. Hunting is an especially interesting behavior, which involves complex cognitive and social behaviors. In order to study rudimentary hunting behaviors in a controlled setting a model org...Hunting; Mouse behavior; ADD/ADHD; Autism2014-06-24
152 Forster, Richard R.Ice surface morphology and flow on Malaspina Glacier, Alaska: Implications for regional tectonics in the Saint Elias orogenThe Saint Elias Mountains in southern Alaska are located at a structural syntaxis where the coastal thrust and fold belt of the Fairweather plate boundary intersects thrust faults and folds generated by collision of the Yakutat Terrane. The axial trace of this syntaxis extends southeastward out of t...2014-01-01
153 Bowling, David R.Impacts of anthropogenic emissions and cold air pools on urban to montane gradients of snowpack ion concentrations in the Wasatch Mountains, UtahUrban montane valleys are often characterized by periodic wintertime temperature inversions (cold air pools) that increase atmospheric particulate matter concentrations, potentially stimulating the deposition of major ions to these snow-covered ecosystems. We assessed spatial and temporal patterns o...2014-01-01
154 Blair, StevenImplantable glass optrodes for deep-tissue light delivery3D needle-type glass waveguide arrays were developed as potentially compact neural interfaces for light delivery in deep-tissue. As much as 90% of input light is transmitted via a single optrode to depths >1mm in tissue. Light emission profiles from the optrode tips into tissue can exhibit beam widt...2014-01-01
155 Sekercioglu, CaganImportance of Ethiopian shade coffee farms for forest bird conservationCoffee is the most important tropical commodity and is grown in high-priority areas for biological conservation. There is abundant literature on the conservation value of coffee farms internationally, but there has been little research on this topic in Africa. Ethiopia is a diverse and little-studie...2014-01-01
156 Scarpulla, MichaelThe importance of Se partial pressure in the laser annealing of CuInSe2 electrodeposited precursorsOne method for producing CuInSe2 (CISe) absorber layers is electrodeposition followed by annealing. Replacing the commonly used furnace annealing step with a laser can reduce annealing times by 2-3 orders of magnitude: from 30 minutes to 1 s. However, laser processing has, to date, not resulted in a...2014-01-01
157 Gerton, JordanImproved localization accuracy in stochastic super-resolution fluorescence microscopy by K-factor image deshadowingLocalization of a single fluorescent particle with sub-diffraction-limit accuracy is a key merit in localization microscopy.

158 Minteer, Shelley D.Improved performance of a thylakoid bio-solar cell by incorporation of carbon quantum dotsCarbon quantum dots (CQDs) were incorporated into thylakoid bioanodes capable of direct photobioelectrocatalysis in order to increase the photocurrent generation. More thylakoids are in contact with the increased surface area which allows for greater direct electron transfer (DET). Additionally, the...2014-01-01
159 Sansone, CarolImproving the dependability of research in personality and social psychology: recommendations for research and educational practiceThe Society for Personality and Social Psychology (SPSP) Presidential Task Force on Publication and Research Practices was appointed in response to concerns about the dependability and replicability of research findings in personality and social psychology, a problem that also plagues fields as dive...2014-01-01
160 Haber, MatthewIn defense of the organism: Thomas Pradeu (Elizabeth Vitanza, trans.): The limits of the self: immunology and biological identity. New York: Oxford University Press, 2012, ix+302 pp, ISBN: 978-0-19-977528-6, $65 HB.Thomas Pradeu's The Limits of the Self provides a precise account of biological identity developed from the central concepts of immunology. Yet the central concepts most relevant to this task (self and nonself ) are themselves deemed inadequate, suffering from ambiguity and imprecision. Pradeu seeks...2014-01-01
161 Minteer, Shelley D.In recognition of Adam Heller and his enduring contributions to electrochemistryRecent progress in diverse scientific fields ranging from bioelectrochemistry to battery technology to photoconversion has been deeply influenced by the contributions of Professor Adam Heller of the University of Texas at Austin to electrochemistry and materials science. This focus issue recognizes ...2014-01-01
162 Frederick, Jeanne M.Inactivity of human β,β-carotene-9′, 10-′dioxygenase (BCO2) underlies retinal accumulation of the human macular carotenoid pigmentThe macula of the primate retina uniquely concentrates high amounts of the xanthophyll carotenoids lutein, zeaxanthin, and meso-zeaxanthin, but the underlying biochemical mechanisms for this spatial- and species-specific localization have not been fully elucidated. For example, despite abundant reti...2014-01-01
163 Wittwer, Carl T.Influence of PCR reagents on DNA polymerase extension rates measured on real-time PCR instrumentsBACKGROUND: Radioactive DNA polymerase activity methods are cumbersome and do not provide initial extension rates. A simple extension rate assay would enable study of basic assumptions about PCR and define the limits of rapid PCR. METHODS: A continuous assay that monitors DNA polymerase extension us...2014-01-01
164 Forster, Richard R.Initial in situ measurements of perennial meltwater storage in the Greenland firn aquiferA perennial storage of water in a firn aquifer was discovered in southeast Greenland in 2011. We present the first in situ measurements of the aquifer, including densities and temperatures. Water was present at depths between ~12 and 37m and amounted to 18.7 ± 0.9 kg in the extracted core. The wate...2014-01-01
165 Stevens, KennethInterfacing synchronous and asynchronous domains for open core protocolIntellectual property (IP) blocks are connected in a system on chip using a bus or network-on-chip (NoC). IP reuse is facilitated by the modularity that results when using common interfaces between the IP cores and the bus or NoC. This paper investigates and implements several versions of one of the...2014-01-01
