We analyzed the V gamma and V delta gene usage in TCR-gamma/delta-bearing T cell clones isolated from human peripheral blood and postnatal thymus using V-specific mAbs and Southern and Northern analyses. In peripheral blood most of the gamma/delta cells express the V gamma 9-JP-C gamma 1 chain paired with a delta chain bearing the V delta 2 gene product. This heterodimer is very rare in the pos...

This paper discusses the design of a very general architectural framework for navigation and tracking systems that fuse dead-reckoning sensors (e.g. inertial or encoders) with environment-referenced sensors, such as ultrasonic, optical, magnetic, or RF sensors. The framework enables systems that simultaneously track themselves, construct a map of landmarks in the environment, and calibrate sens...

To determine why North Americans tend to locate European cities south of North American cities at similar latitudes (Tversky, 1981), we had observers provide bearing estimates between cities in the U.S. and Europe. Earlier research using latitude estimates of these cities has indicated that each continent has several subjective regions (Friedman & Brown, 2000a). Participants judged cities from ...

Mid-infrared spectromicroscopy studies on biological tissue sections require accurate identification of tumor-bearing areas in histology-stained and infrared-unstained tissue sections. Concordance was achieved as follows: paired stained and unstained thin (5 microm) human brain tumor cryosections mounted on slides were scanned with a Nikon Coolscan 4000 film scanner at 4000 dpi, edited with Ado...

Spleen extracts and sera from C57BL/10 mice bearing a reticulum cell lymphoma were found to contain elevated levels of protein when compared with normal mouse levels. Immunodiffusion, immunoelectrophoresis, gel filtration, and density gradient ultracentrifugation studies indicated the protein to be an IgM macroglobulin. The increased macroglobulin level was correlated, in part, with the growth ...

AIMS The aim of this study was to investigate the antimetastatic effect of multiple antigenic polypeptide (MAP) vaccine based on B-cell epitopes of heparanase (HPSE) on human hepatocellular carcinoma (HCC) in vivo. METHODS The antiserum against B-cell epitopes of HPSE was isolated, purified and characterized after immunizing white-hair-black-eye (WHBY) rabbit with freshly synthesized MAP vacc...

In this paper, the effectiveness of stiffness and damping of bearing is investigated on the natural frequencies of the rotor-bearing system. The rotor-bearing system consists of a shaft, two bearings and a disk between two bearings. Parallel spring-damper in horizental and vertical directions is considered for modeling the stiffness and damping of bearings. The gyroscopic effect is also conside...

Squeeze Film Dampers (SFD) are commonly used for passive vibration control of rotor-bearing systems. The Magnetorheological (MR) and Electrorheological (ER) fluids in SFDs give a varying damping characteristic to the bearing that can provide active control schemes for the rotor-bearing system. A common way to model an MR bearing is implementing the Bingham plastic model. Adding this model to th...

Abnormal placental invasions continue to be a major problem in obstetrics and gynecology. It is cause of obstetric hemorrhage, with high risk mortality morbidity. Morbidly Adherent Placenta (MAP) has become more common recent years as result variety factors. Despite being highly sensitive specific, routine pregnancy ultrasound can miss MAP diagnosis. As result, other imaging modalities must use...

The partially correlative Alaskan dinosaur-bearing Prince Creek Formation (PCF), North Slope, lower Cantwell (LCF), Denali National Park, and Chignik (CF), Aniakchak Monument, form an N–S transect that, together, provides unparalleled opportunity to examine ancient high-latitude terrestrial ecosystem. PCF, 75–85° N paleolatitude, had a Mean Annual Temperature (MAT) of ~5–7 °C Precipitation (MAP...
