The paper presents a construction of the crossed product of a C *-algebra by a semigroup of endomorphisms generated by partial isometries.

New radio observations of the radio-jet X-ray binary Circinus X-1 over nearly an entire 16.6-day orbit are presented. The source continues to undergo radio flaring in the phase interval 0.0 – 0.2 and appears to be brightening since observations in the early 1990s. The radio flux density is well correlated with simultaneous soft Xray monitoring from the XTE ASM, including a secondary flare event...

Background: Uterine leiomyoma (UL) is a benign tumor of uterine smooth muscle that affects women in reproductive ages. FAS has an important role in initial stages of apoptosis. Previous studies have shown an association between the FAS gene and tumorigenesis. In the present study, we evaluated the relationship between FAS A-670G (rs 1800682) and UL risk. Methods: The FAS gene polymorphism of...

We present a classical formalism describing two-time physics with background gauge fields. The formalism has an irreducible version that can be used as a starting point for the construction of a quantized two-time physics theory with a minimum length in a noncommutative Lorentz-covariant space-time.

Low-harmonic formulas for closed relativistic strings are given. General parametrizations are presented for the addition of second-and third-harmonic waves to the fundamental wave. The method of determination of the parametriza-tions is based upon a product representation found for the finite Fourier series of string motion in which the constraints are automatically satisfied. The construction ...

We review the spectroscopy and some properties of hadrons containing two charmed quarks, or more generally, two heavy quarks. This includes heavy baryons such as (bcu), and possible exotic multiquark states.
