CD16+ monocytes represent 5-10% of peripheral blood monocytes in normal individuals and are dramatically expanded in several pathological conditions including sepsis, human immunodeficiency virus 1 infection, and cancer. CD16+ monocytes produce high levels of proinflammatory cytokines and may represent dendritic cell precursors in vivo. The mechanisms that(More)
In this paper, we evaluate performance of a real-world image processing application that uses a cross-correlation algorithm to compare a given image with a reference one. We implement this algorithm on a nVidia GTX 285 GPU using CUDA, and also parallelize it for the Intel Xeon (Nehalem) and IBM Power7 processors, using both manual and automatic techniques.(More)
The early visual cortices represent information of several stimulus attributes, such as orientation and color. To understand the coding mechanisms of these attributes in the brain, and the functional organization of the early visual cortices, it is necessary to determine whether different attributes are represented by different compartments within each(More)
Information about various visual attributes orientation and color is represented in the primate striate cortex (V1) before reaching extrastriate cortices. An important question regarding the functional architecture of V1 is whether these dierent attributes are represented by separate populations of neurons. However, previous studies using single-or(More)
We studied the effects of prenatal cocaine and morphine given separately and in combination on the (1) postnatal brain mu-opioid receptor development and (2) interaction of dopamine with mu receptors. Pregnant rats received single daily intraperitoneal (I.P.) injections of saline, cocaine (20 mg/kg), morphine (2 mg/kg), or the combination of both drugs from(More)
This position paper summarizes some of our initial work, as well as future research opportunities, in the area of augmenting human mental functioning via a real-time analysis of various measurements reflecting person's physiological and mental states. EEG, heart rate, blood pressure, and galvanic skin response, among several other measurements, can be(More)
Pregnant rats received daily injections of saline, cocaine (20 mg/kg), morphine (2 mg/kg), or the combination of both drugs, on days 13-20 of gestation. Cyclin-dependent kinase 5 (Cdk5) activity was then measured in the resulting pups on postnatal days 1, 7, 14 and 28. Cocaine resulted in a time dependent increase in brain Cdk5 activity which peaked on day(More)
