The Taurus Tunable Filter Field Galaxy Survey: Sample Selection and Narrowband Number-Counts [PDF]

open access: yes, 2001
Recent evidence suggests a falling volume-averaged star-formation rate (SFR) over z ~ 1. It is not clear, however, the extent to which the selection of such samples influences the measurement of this quantity.

Enumerating number fields [PDF]

open access: yesAnnals of Mathematics, 2020
We construct small models of number fields and deduce a better bound for the number of number fields of given degree and bounded discriminant.

Quantitative Riemann existence theorem over a number field

open access: yes, 2009
Given a covering of the projective line with ramifications defined over a number field, we define a plain model of the algebraic curve realizing the Riemann existence theorem for this covering, and bound explicitly the defining equation of this curve and

BLAST Observations of the South Ecliptic Pole field: Number Counts and Source Catalogs [PDF]

open access: yes, 2010
We present results from a survey carried out by the Balloon-borne Large Aperture Submillimeter Telescope (BLAST) on a 9 deg^2 field near the South Ecliptic Pole at 250, 350 and 500 {\mu}m.

PAC fields over number fields [PDF]

open access: yesJournal de théorie des nombres de Bordeaux, 2008
We prove that if K is a number field and N is a Galois extension of ℚ which is not algebraically closed, then N is not PAC over K.

Computing quadratic subfields of number fields

open access: yesJournal of Computational Algebra
Given a number field, it is an important question in algorithmic number theory to determine all its subfields. If the search is restricted to abelian subfields, we can try to determine them by using class field theory.

The Genus Field and Genus Number in Algebraic Number Fields [PDF]

open access: yesNagoya Mathematical Journal, 1967
Let k be an algebraic number field and K be its normal extension of finite degree. Then the genus field K* of K over k is defined as the maximal unramified extension of K which is obtained from K by composing an abelian extension over k2). We call the degree (K*: K) the genus number of K over k.

Effects of Regional Magnetic Field on Rotating MHD Flow Field of Unity Magnetic Prandtl Number

open access: yesJournal of Applied Mathematics, 2012
This work numerically studies the flow pattern of a magnetic fluid filled within an annulus whose inner cylinder is moving at a constant rotational speed, while the outer cylinder is stationary but under the influence of a nonuniform external magnetic ...

Improving the Evaluation and Management of Transfusion‐Related Iron Overload in Children, Adolescents, and Young Adults Following Cancer Treatment or Hematopoietic Stem Cell Transplantation

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background Transfusion‐related iron overload (TRIO) is a late effect of therapy impacting survivors of childhood cancer and hematopoietic stem cell transplantation (HSCT) who receive frequent packed red blood cell (pRBC) transfusions. Surprisingly, there are no accepted guidelines to assist providers in identifying and treating at‐risk ...

Far-Ultraviolet Number Counts on Field Galaxies [PDF]

open access: yes, 2011
The far-ultraviolet (FUV) number counts of galaxies constrain the evolution of the star formation rate density of the universe. We report the FUV number counts computed from FUV imaging of several fields including the Hubble Ultra Deep Field, the Hubble ...
