Moisture Induced Electron Traps and Hysteresis in Pentacene-Based Organic Thin-Film Transistors
Previous work revealed that electron traps in pentacene formed in air cause hysteresis in thin-film transistor characteristics. Here, we experimentally showed that water vapor, rather than oxygen, is responsible for these hysteresis-causing trap states.

Evaluation of a Near-Field Monostatic-To-Bistatic Equivalence Theorem
This paper presents the results of an investigation to quantitatively determine the limits of Falconer's monostatic-to-bistatic equivalence theorem (MBET).

Frontal Callosal Fiber Integrity Selectively Predicts Coordinated Psychomotor Performance in Chronic Alcoholism
Quantitative fiber tracking with diffusion tensor imaging (DTI) provides a new approach for assessing deficits in the microstructural integrity of white matter circuits that may underlie cognitive deficits associated with…

Role of Nucleation on the Growth of Nanocrystalline Diamond (NCD) Films: a Particular Study in the Fabrication of Micro-Cantilevers
It was observed that the films grown after pre-treating the substrates in pure nanodiamond slurry have not provided a complete coverage at the anchor regions of the cantilevers due to…

Mosaicing of Single Plane Illumination Microscopy Images Using Groupwise Registration and Fast Content-Based Image Fusion
We propose here an image mosaicing algorithm that combines state of the art groupwise image registration for alignment with content-based image fusion to prevent degrading of the fused image due…

Roles of Insulin and Transferrin in Neural Progenitor Survival and Proliferation
In the current study, we examined the requirements for NSC proliferation and survival in vitro using the neurosphere culture system.

Risking Communications Security: Potential Hazards of the Protect America Act
A new US law allows warrantless wiretapping whenever one end of the communication is believed to be outside national borders. This creates serious security risks: danger of exploitation of the…
