Effect of Fenoterol Stereochemistry on the β2 Adrenergic Receptor System: Ligand-Directed Chiral Recognition
The β2 adrenergic receptor (β2-AR) is a model system for studying the ligand recognition process in G protein-coupled receptors. Fenoterol (FEN) is a β2-AR selective agonist that has two centers of…

Language-independent constrained cepstral features for speaker recognition
We develop language-independent (LI) versions of constraints and compare results to parallel LD versions for English data on the NIST 2008 interview task.

Automatic identification of speaker role and agreement/disagreement in broadcast conversation
We present supervised approaches for detecting speaker roles and agreement/disagreement between speakers in broadcast conversation shows in three languages: English, Arabic, and Mandarin.

Comparison of 32 x 128 and 32 x 32 Geiger-Mode APD FPAs for Single Photon 3D LADAR Imaging
We present results obtained from 3D imaging focal plane arrays (FPAs) employing planar-geometry InGaAsP/InP Geiger-mode avalanche photodiodes (GmAPDs) with high-efficiency single photon sensitivity at 1.06 μm.

Identity in the Federal Learning Registry
The Learning Registry helps alleviate the problem of disparate standards for describing resources by changing the business model for suppliers from hand-curation of descriptive data to tapping data streams from…

Monitoring CD4 in whole blood with an opto-fluidic detector based on spatially modulated fluorescence emission
An optical detection technique termed spatially modulated fluorescence emission is described that delivers high signal-to-noise discrimination without precision optics to enable a flow cytometer that can combine high performance, robustness,…

Inkjet-patterned titanium oxide memristive junctions connected in series for a threshold indicator
Here memristive metal/oxide/metal junctions were patterned by inkjet printing, and the printed device characteristics were measured to infer ionic and electronic transport parameters such as mobilities and ion distribution.

Materials and device integration for printed large area applications
In this talk, I will discuss the development integrated sensing systems to illustrate and demonstrate the challenges and advantages of using solution-processed electronic materials for flexible applications.

Surface-energy patterning for ink-jet printed flexible electronics
We have investigated different photolithographically defined anti-wetting materials to form the surface energy pattern, including an alkyl functionalized polysilsesquioxane (PSSQ), and perfluoropolymers such as polytetrafluoroethylene (PTFE).

Disordered nanowire based photovoltaics
In this paper we present experimental results incorporating traditional amorphous silicon (a-Si) photovoltaic devices with a three-dimensional, disordered nanowire (NW) mat using approaches that are compatible with current large area…
