WebRTC is a new technology allowing web players to offer communication services to their customers. It optimizes the communications by privileging peer-to-peer connections. However, in restrictive networks, media relays (TURN servers) are mandatory for establishing the call. The location and behavior of these media relays can have an undesirable influence on the quality of real-time communicati...

Threshold biasing of a Gaussian random field gives a linear amplification of the reduced two point correlation function at large distances. We show that for standard cosmological models this does not translate into a linear amplification of the power spectrum (PS) at small k. For standard CDM type models this means that the “turn-over” at small k of the original PS disappears in the PS of the b...

The "information age" is reliant upon the information skill-base of people and the storage and access of complete data. Staff turn-over and "down-sizing" as well as the rate of organisational change places increased pressure on the designers of corporate information systems to keep up with the organizational demands. Especially relevant are the "soft" aspects of the corporate information needs ...

We study numerically the so-called “turn-over scenario” for rotating magnetic white dwarfs and neutron stars. According to this scenario, the magnetic symmetry axis of the model inclines at a gradually increasing angle (the so-called “turn-over angle”) relative to the invariant angular momentum axis. Consequently, the model becomes “perpendicular rotator” (i.e., its turn-over angle becomes almo...

Keratin polypeptides 8 and 18 (K8/18) are intermediate filament (IF) proteins that are expressed in glandular epithelia. Although the mechanism of keratin turnover is poorly understood, caspase-mediated degradation of type I keratins occurs during apoptosis and the proteasome pathway has been indirectly implicated in keratin turnover based on colocalization of keratin-ubiquitin antibody stainin...

MAGE-A proteins are testis-specific E3 ubiquitin ligase components whose expression is upregulated in many cancers. MAGE-A3 and -A6 act as oncogenes and recent work now shows that they degrade the central metabolic regulator AMPK, providing a novel mechanism for rewiring cancer metabolism.

The very low abundance of mitochondrial DNA (mtDNA) mutations in nearly all mammalian tissues even in old age has led most mitochondriologists to reject the idea that such mutations might have a causal role in aging, despite (1) the strong circumstantial (e. g., interspecies) evidence that they do have such a role, (2) the promulgation since 1998 of two detailed mechanisms whereby low levels of...

We report on the status of emittance tuning techniques at the CESR Test Accelerator (CesrTA). The CesrTA experimental program requires that we operate in a variety of machine lattices, each with the smallest possible emittance. We utilize high-bandwidth BPM electronics for fast, precision measurements of orbit, betatron phase, transverse coupling, and dispersion. Analysis of the data and implem...
