Results on soft and hard diffraction obtained by the CDF Collaboration in Run I of the Fermilab Tevatron p̄p collider are reviewed and compared with results from the DESY ep collider HERA and with theoretical expectations. In addition, the CDF program for diffractive studies in Run II is briefly reviewed with emphasis on the relevant detector upgrades and physics goals.

The phenomenology of b-production and some of the previous Run I measurements of CDF and DØ are briefly reviewed. A new analysis by CDF of Run I b ¯ b angular correlations and a new measurement by DØ of Run II b-jet cross-section, are presented.

The cardiac voltage gated Ca(2+) current (ICa) is critical to the electrophysiological properties, excitation-contraction coupling, mitochondrial energetics, and transcriptional regulation in heart. Thus, it is not surprising that cardiac ICa is regulated by numerous pathways. This review will focus on changes in ICa that occur during the cardiac action potential (AP), with particular attention...

The failure probability of engineering structures such as aircraft, bridges, dams, nuclear structures, and ships, as well as microelectronic components and medical implants, must be kept extremely low, typically <10(-6). The safety factors needed to ensure it have so far been assessed empirically. For perfectly ductile and perfectly brittle structures, the empirical approach is sufficient becau...

We present Chandra point-source catalogs for the Extended Chandra Deep Field-South (E-CDF-S) survey. The E-CDF-S consists of four contiguous 250 ks Chandra observations covering an approximately square region of total solid angle ≈0.3 deg2, which flank the existing ≈1 Ms Chandra Deep Field-South (CDF-S). The survey reaches sensitivity limits of ≈1.1 × 10−16 erg cm−2 s−1 and ≈6.7 × 10−16 erg cm−...

We present the latest results on the search for bottom baryon states Σb using ∼ 1 fb of CDF data. The study is performed with the world’s largest sample of fully reconstructed Λb decays collected by CDF II detector at √ s = 1.96TeV in the hadronic trigger path. We observe 4 new states consistent with Σ (∗)± b bottom baryons.

This paper summarizes the main current upgrade for Diffractive Physics at Tevatron. We describe both CDF (Collider Detector Facility) and DØ new devices that are being installed around the CDF and DØ area that will allow to produce new results in Diffractive Physics.

Abstract Cantor sets are constructed from iteratively removing sections of intervals. This process yields a cumulative distribution function (CDF), the invariant Borel probability measure associated with their iterated systems. Under appropriate assumptions, we identify sampling schemes such CDFs, meaning that underlying set can be reconstructed sufficiently many samples its CDF. To this end, p...

Voltage-gated Ca2+ channels (VGCCs) of the P/Q-type, which are expressed at a majority of mammalian nerve terminals, show two types of Ca2+-dependent feedback regulation-inactivation (CDI) and facilitation (CDF). Because of the nonlinear relationship between Ca2+ influx and transmitter release, CDI and CDF are powerful regulators of synaptic strength. To what extent VGCCs inactivate or facilita...

The human neuroblastoma cell line IMR-32 exhibits both cholinergic and adrenergic properties. We have used IMR-32 cells to study the effects of CDF (CAT development factor) and bFGF (basic fibroblast growth factor) on the development of neurotransmitter properties. CDF treatment increases CAT activity in a dose-dependent manner, independent of cell density. Time course studies show that there i...
