Artificial atoms are a cornerstone of emerging technologies that promise to make practical use of the laws of quantum mechanics. In principle, artificial atoms should behave like real atoms but be compatible with a solidstate environment. As such, they could serve as solidstate quantum bits (qubits) ideally suited to interfacing with photonic qubits. They could store, manipulate, and retrieve q...

One of the fundamental and puzzling questions in vision research is how objects are segmented from their backgrounds and how object formation evolves in time. The recently discovered shine-through effect allows one to study object segmentation and object formation of a masked target depending on the spatiotemporal Gestalt of the masking stimulus (Herzog & Koch, 2001). In the shine-through effec...

We characterize the Shine and Dalgarno sequence of 124 known gene beginnings. This information is used to make "rules" which help distinguish gene beginning from other sites in a library of over 78,000 bases of mRNA. Gene beginnings are found to have information besides the initiation codon and Shine and Dalgarno sequence which can be used to make better "rules".

INTRODUCTION It is well documented that practicing phrsicians have serious unmet information needs. The SKOLAR system, which grew out of the Stanford Health Information Network for Education (SHINE) system , was built to address these real information needs. SKOLAR allows users to search multiple resources simultaneously with a single, integrated search. These resources include textbooks, drug ...

Chloroplast mRNAs in Euglena gracilis fall into two classes. One class has a Shine-Dalgarno sequence 5' to the AUG start codon while the other group of mRNAs does not have any conserved sequence elements near the start codon. The chloroplast mRNA encoding the atpH gene has been selected as an example of a message which has a Shine-Dalgarno sequence (GGAGUU) located in the initiation region. Mut...

BACKGROUND Human immunodeficiency virus and acquired immunodeficiency syndrome (HIV/AIDS) remains a significant international public health challenge. The Statewide HIV/AIDS Information Network (SHINE) Project was created to improve HIV/AIDS health information use and access for health care professionals, patients, and affected communities in Indiana. OBJECTIVE Our objective was to assess the...
