Enhanced vertical and lateral hole transport in high aluminum-containing AlGaN for deep-UV light emitters
We report improved p-type conductivity in AlGaN:Mg superlattice (SL) cladding layers designed for deep ultraviolet light emitting devices operating at wavelengths down to 255 nm.

Origin of the tunable open circuit voltage in ternary blend bulk heterojunction organic solar cells
Ternary blend bulk heterojunction organic solar cells comprising two polythiophene polymer donors or two fullerene acceptors are shown to have unique electronic properties.

Electronic structure and mobility of alkylated and nonalkylated organic semiconductors: role of van der Waals interactions
We present a comparison based on first-principles calculations of the electronic structure of nonalkylated and alkylated dinaphtho[2,3-b:2,3-f]thieno[3,2-b]thiophene: DNTT and DNTT-C10.

Flow cytometry on a chip
After a brief review of some new technologies important for on the flow anayte characterization we will describe an optical detection technique termed spatially modulated fluorescence emission developed at PARC…

Persistent photoconductivity effects in printed n-channel organic transistors
Persistent photoconductivity of top-gate n-type organic transistors is investigated, as the irradiation of light leads to a negative shift in transistor threshold voltage and an increase in subthreshold current.

Early childhood language interventions: An illustration of the model demonstration process
This project brief summarizes the characteristics, implementation experiences, and outcomes achieved by one of OSEP’s investments in model demonstration activities—a cohort of three grantees that demonstrated various approaches to implementing…

A review of literature: Mix it up with blended learning in K-12 schools
The term “blended learning” represents a wide spectrum of delivery options, tools, and pedagogies, but conceptually refers to instruction that is a mix or blending of traditional face-to-face (f2f) and…

Measuring Flow Complexity in Videos
In this paper a notion of flow complexity that measures the amount of interaction among objects is introduced and an approach to compute it directly from a video sequence is…

A Role for Cortical nNOS/NK1 Neurons in Coupling Homeostatic Sleep Drive to EEG Slow Wave Activity
These findings support the hypothesis that cortical nNOS/NK1 neurons translate homeostatic sleep drive into up-regulation of NREM δ power through an NO-dependent mechanism.

Rapid Identification of Sequences for Orphan Enzymes to Power Accurate Protein Annotation
In this study, we demonstrate how this orphan enzyme “back catalog” is a fertile source for rapidly advancing the state of protein annotation.
-
Comparison of Ionospheric Drift and Magnetic Deflections on the Ground
We conclude that a sunward magnetic contribution on the order of 50 nT caused by magnetospheric currents is needed to explain the offset.

Dynamic Pooling for Complex Event Recognition
Complex events are defined as events composed of several characteristic behaviors, whose temporal configuration can change from sequence to sequence.
