Measuring Hanbury Brown-Twiss correlations of pions in high-energy nucleus-nucleus collisions
This dissertation examines how particle detectors extract information about correlations due to the Hanbury Brown-Twiss (HBT) effect for identical pions from the collision debris of a high-energy collision between two heavy nuclei. The basic ingredients of HBT correlations are: the exchange …

The nucleus of Centaurus A
… the central r<1.5 arcsec of the active galactic nucleus are successfully described by a (warped) gas disk, rotating in the joint gravitational potential of the stars and a black hole of Mbh~7x10^7 Msolar. With our revised Mbh estimate, that is a factor ~3 lower than previous measurements, Cen A …

Kinematic Demands of Nucleus Arthroplasty Technology
… One application of immediate interest is that of nucleus arthroplasty (NA). Novel materials are being developed to better match the nonlinear biomechanical properties of the native tissue. The effects of changing the motion segment unit (MSU) properties via surgery (nucleotomy) or placement of a …

Ribose nucleic acid and the cell nucleus
1. Methods of estimation of ribose nucleic acid are discussed and a reliable method for the estimation of that substance in isolated cell nuclei described.

Tracking translation factors in fission yeast nucleus
Translation factors are essential components of the ribosome, yet it has been reported that many ribosomal proteins (RPs) and other translation factors are found at transcription sites of Drosophila melanogaster (D. melanogaster) polytene chromosomes. Whilst these findings might indicate the …

Responses from electric stimulation of cochlear nucleus
Cochlear nucleus (CN), the exclusive destination of the auditory nerve, is the gateway for all central processing of auditory information. The CN comprises three major subdivisions: anteroventral, posteroventral and dorsal (AVCN, PVCN and DCN, respectively), each of which contains anatomically and …

Mechanobiology of the nucleus pulposus: The effect of hydrostatic pressure and glucose deprivation on nucleus pulposus cell sub‐populations
The nucleus pulposus of the intervertebral disc contains two cell types: notochordal (NC) and chondrocyte‐like mature nucleus pulposus (MNP) cells; the ratio of which changes with species, age and health. Intervertebral disc (IVDs) that contain predominantly MNP cells are susceptible to …

An in Vitro Microenvironment for Nucleus Pulposus Regeneration
… in disc failure. At the center of the disc, the nucleus pulposus (NP) resides in a hypoxic environment where degeneration is thought to begin. Initially, nucleus pulposus cells (NPCs) display altered morphology and function, along with increased rates of cellular senescence and apoptosis. Though …

A Molecular Dissection of the Ventromedial Hypothalamic Nucleus
<p>The ventromedial hypothalamic nucleus (VMH) plays an important role in the regulation of food intake, glucose metabolism, and body weight. However, in contrast to other hypothalamic nuclei that are also known to regulate energy homeostasis, there is a paucity of nucleus-specific marker genes for …

Phosphoproteins of the Cell Nucleus: Metabolism and Characterization
… metabolism as it occurs in the intact nucleus under varying conditions, and then on the chemistry and enzymology of a phosphoprotein fraction which has been extracted and purified from isolated nuclei. The metabolism of phosphoproteins was studied in isolated calf thymus nuclei …

Theory of Alpha-Nucleus Collisions at High Energies
… equations derived from Watson's form of the nucleus-nucleus multiple scattering series are shown to be equivalent to the Glauber multiple scattering series. Second-order solutions for the elastic amplitude are developed and used to study the effects of short-range correlations in nuclear …

Role of the Parabigeminal Nucleus in Visuomotor Behavior
The parabigeminal nucleus (PBN) is a small satellite of the superior colliculus, located on the edge of the midbrain. To identify activity related to visuomotor behavior, we recorded from PBN cells in cats trained to fixate moving and stationary targets. Cats tracked moving targets primarily with …

Morphogenesis of the lateral geniculate nucleus in primates
The lateral geniculate nucleus (LGN) is the part of the mammalian visual system that relays information from the eye to the cerebral cortex. In the rhesus macaque monkey, the LGN exhibits an intricate lamination pattern, which changes midway through the nucleus at a point coincident with small gaps …
