Proceedings of the American Mathematical Society, 1961 The above sequences have the following interpretation [2]: the elements which are -1 are those with subscript given mod n by n=5: Mn4+3, mf O (mod5), n= 7: rm2+3, mf O (mod7), n = 11: -M2 2, (mod 11), n = 13: llm4 1, (mod 13). It will be shown here that for odd n, these are all the sequences with the property Ck I < 1. For the sake of completeness, the

FEBS Letters, EarlyView.UDP‐glucuronic acid 4‐epimerase (UGAepi) catalyzes NAD+‐dependent interconversion of UDP‐glucuronic acid (UDP‐GlcA) and UDP‐galacturonic acid (UDP‐GalA) via C4‐oxidation, 4‐keto‐intermediate rotation, and C4‐reduction. Here, Borg et al. examined the role of the substrate's carboxylate group in the enzymic mechanism by analyzing NADH‐dependent reduction

Open Astronomy, 2010 The spectroscopic orbit of a high proper motion star, BD+20 5152, is calculated from 34 CORAVEL-type radial velocity measurements. The star has a slightly eccentric orbit with a period of 5.70613 d, half-amplitude of 47.7 km/s and eccentricity of 0.049 ...

Beyond binaries : a way forward for comparativeeducation
Revista Española de Educación Comparada, 2012 Binary discourses shape and produce the stories we construct about the field of comparative education. In the first part of this article, I review a set of binary discourses that have characterized social science research since the Enlightenment ...

Quasi periodic oscillations in black hole binaries [PDF]
, 2016 Fast time variability is the most prominent characteristic of accreting systems and the presence of quasi periodic oscillations (QPOs) is a constant in all accreting systems, from cataclysmic variables to AGNs, passing through black hole and neutron star

Molecular Oncology, EarlyView.Circulating tumor DNA (ctDNA) offers a possibility for different applications in early and late stage breast cancer management. In early breast cancer tumor informed approaches are increasingly used for detecting molecular residual disease (MRD) and early recurrence. In advanced stage, ctDNA provides a possibility for monitoring disease progression and

Correction of UBV Photometry for Emission Lines
Open Astronomy, 2003 We investigate the effect on U,B,V magnitudes of the removal of emission lines from the spectra of some symbiotic stars and novae during their nebular phases.

THE ELM SURVEY. VII. ORBITAL PROPERTIES OF LOW-MASS WHITE DWARF BINARIES [PDF]
, 2016 We present the discovery of 15 extremely low-mass ( 5 < log g < 7 ?> ) white dwarf (WD) candidates, 9 of which are in ultra-compact double-degenerate binaries. Our targeted extremely low-mass Survey sample now includes 76 binaries.

Search for Supermassive Black Hole Binaries in the Sloan Digital Sky Survey Spectroscopic Sample
, 2013 Supermassive black hole (SMBH) binaries are expected in a Lambda CDM cosmology given that most (if not all) massive galaxies contain a massive black hole at their center. So far, however, direct evidence for such binaries has been elusive.
