Functional visual fields: relationship of visual field areas to self‐reported function [PDF]

Ophthalmic and Physiological Optics, 2017
AbstractPurposeThe aim of this study is to relate areas of the visual field to functional difficulties to inform the development of a binocular visual field assessment that can reflect the functional consequences of visual field loss.MethodsFifty‐two participants with peripheral visual field loss undertook binocular assessment of visual fields using ...

Automorphisms of Function Fields [PDF]

Transactions of the American Mathematical Society, 1955
1. Let K be an algebraic function field of one variable over the constant field k and let g > 0 be the genus of K. Let 9 be the group of all automorphisms of K that leave the elements of k fixed (and that leave a given place Po of K/k fixed if g = 1). A classical theorem due to Schwartz-Klein-NoetherWeierstrass-Poincar&-Hurwitz when g>1 (and older for ...

Partition function of massless scalar field in Schwarzschild background [PDF]

, 2014
Using thermal value of zeta function instead of zero temperature, the partition function of quantized fields in arbitrary stationary backgrounds was found to be independent of undetermined regularization constant in even-dimension and the long drawn ...

Sieving in Function Fields

Experimental Mathematics, 1999
We present the first implementation of sieving techniques in the context of function fields. More precisely, we compute in class groups of quadratic congruence function fields by combining the algorithm of Hafner and McCurley with sieving ideas known from factoring.

Response function beyond mean field of neutron-rich nuclei [PDF]

, 1998
The damping of single-particle and collective motion in exotic isotopes is a new topic and its study may shed light on basic problems of nuclear dynamics.

Fertilization and intercropping reduce Pb accumulation in plants by influencing rhizosphere soil phosphorus forms in soil-plant systems

Ecotoxicology and Environmental Safety
Fertilization and planting practices in crop systems have become important ways to reduce the uptake of heavy metals in polluted soils. However, the relative effectiveness of different management modes and the underlying mechanisms are not fully ...

The luminosity function of field galaxies

, 2011
Schmidt's method for construction of luminosity function of galaxies is generalized by taking into account the dependence of density of galaxies from the distance in the near Universe.

The K-band luminosity function of nearby field galaxies [PDF]

, 1999
We present a measurement of the K-band luminosity function (LF) of field galaxies obtained from near-infrared imaging of a sample of 345 galaxies selected from the Stromlo-APM Redshift Survey. The LF is well-fitted over the ten magnitude range -26 < M_K <

Hypergeometric Functions for Function Fields

Finite Fields and Their Applications, 1995
Let \(\{a,b,c\}\) be complex constants. Then the famous Gauss hypergeometric equation is given by \[ z(1 - z) {d^2y \over dz^2} + \bigl( c - (a + b + 1) z \bigr) {dy \over dz} - aby = 0. \] One defines the Pochhammer symbol \((a)_n\) by \((a)_0 : = 1\) and for \(n > 1\), \((a)_n : = a(a + 1) (a + 2) (a + 3) \cdots (a + n - 1)\).

Synergistic ecotoxicity of nanoscale zero-valent iron and cadmium in soil: Insights from Eisenia fetida

Ecotoxicology and Environmental Safety
Nano-zero-valent iron (nZVI) has been extensively applied as a soil conditioner in remediation practices. However, studies have suggested that excessive doses of nZVI can adversely affect soil organisms and even exacerbate the toxicity of contaminants ...
