Neuronal activities often exhibit rythmic patterns, with a frequency that changes from one band to another. These oscillations can be reproduced in network models of coupled inhibitors. However, the mechanism that controls the period of the oscillations is not fully understood. Recent studies have shown that various types of inhibitory interneurons may release transmitters synchronously or asyn...

We have measured gluon splitting into bottom quarks, g → bb̄, in hadronic Z0 decays collected by SLD between 1996 and 1998. The analysis was performed by looking for secondary bottom production in 4-jet events of any primary flavor. 4-jet events were identified, and in each event a topological vertex-mass technique was applied to the two jets closest in angle in order to identify them as b or b ...

This paper addresses the question of sufficient breadth and depth for undergraduate engineering curriculum in the area of microelectronics, based on input from an industrial panel. This panel was formed as part of a NSF Course and Curriculum Development (CCD) grant to help define the appropriate mix between specific skills, fundamentals, and exposure to current technology. Their input calls for...

A system for analysing can lids is presented Im ages of the can lids are captured by a CCD camera The images are then analysed to determined whether the cans are with or without imprinted text on the lid The system is also capable of detecting whether the can is viewed from the top or the bottom The performance of the system is promising yet there are possibilities

We present CCD photometry of the long period asteroid 1689 Floris-Jan. On the light curve from nights 1997.02.10/11 and 1997.02.11/12 we detected sine-like oscillations with the period P=4.98 ± 0.01 minutes and full amplitude about 0.11 mag. Observations from night 1997.03.07/08 show no light variations at this period.

Identifying genes that are involved in the development of cancer has been a very important research goal. One approach tries to identify genes in tumors that have an increased mutation rate. [Sjöblom et al., 2006] sequenced 13,023 CCDS genes in breast and colorectal cancer tumors. CCDS genes are protein encoding genes and represent the most highly curated gene set currently available. The data ...

In this article we present a detailed discussion of noise sources in Fourier Domain Optical Coherence Tomography (FDOCT) setups. The performance of FDOCT with charge coupled device (CCD) cameras is compared to current standard time domain OCT systems. We describe how to measure sensitivity in the case of FDOCT and confirm the theoretically obtained values. It is shown that FDOCT systems have a ...
