Survey completeness of a global citizen-science database of bird occurrence（图）
Survey completeness global citizen-science database bird occurrence
2019/10/28
There are many shortfalls in knowledge of the world's biodiversity, and one of the most basic is the lack of knowledge about where species occur geographically. This deficiency has broad ramifications...
Characterizing model completeness among mutually algebraic structures
algebraic structures model completeness
2015/9/28
We characterize when the elementary diagram of a mutually algebraic
structure has a model complete theory, and give an explicit
description of a set of existential formulas to which every formula
i...
Model completeness for trivial, uncountably categorical theories of Morley rank one
uncountably categorical theories Model completeness
2015/9/28
The present paper is a direct continuation of [2], where it is shown that any strongly
minimal trivial theory is model complete after naming constants for a model. In this
paper we show that this re...
Borel completeness of some aleph_0 stable theories
Borel completeness some aleph_0 stable theories
2015/9/25
We study ℵ0-stable theories, and prove that if T either has eniDOP
or is eni-deep, then its class of countable models is Borel complete.
We introduce the notion of λ-Borel completeness and pro...
Assessing the completeness of Italian historical earthquake data
completeness historical earthquakes seismic hazard
2015/9/14
The assessment of the completeness of historical earthquake data (such as, for instance, parametric earthquake catalogues) has usually been approached in seismology - and mainly in Probabilistic Seism...
Nature and completeness of galaxies detected in the Two Micron All Sky Survey
surveys general fundamental parameters.
2014/12/24
The Two Micron All Sky Survey (2MASS) provides the most comprehensive data set of near-infrared galaxy properties. We cross correlate the well-defined and highly complete spectroscopic selection of ov...
Bergman completeness is not a quasi-conformal invariant
quasi-conformal invariant Bergman completeness Complex Variables
2011/9/22
Abstract: We show that Bergman completeness is not a quasi-conformal invariant for general Riemann surfaces.
Homotopy categories and idempotent completeness, weight structures and weight complex functors
Homotopy category idempotent completeness weight structure w-structure weight complex functor
2011/8/26
Abstract: This article provides some basic results on weight structures, weight complex functors and homotopy categories. We prove that the full subcategories K(A)^{w < n}, K(A)^{w > n}, K(A)^- and K(...
Completeness III: identifying characteristic systematics and evolution in galaxy redshift surveys
Cosmology: methods: data analysis – methods:redshift surveys – galaxies: large-scale structure of Universe
2011/9/28
This paper continues our development of non-parametric tests for analysing the completeness in apparent magnitude of magnitude-redshift surveys. The purpose of this third and final paper in our comple...
Duality Gap, Computational Complexity and NP Completeness: A Survey
Duality Gap Computational Complexity NP Completeness
2011/2/28
In this paper, we survey research that studies the connection between the computational complexity of optimization problems on the one hand, and the duality gap between the primal and dual optimizatio...
Completeness of the Bethe ansatz on Weyl alcoves
Bethe ansatz root systems spectral analysis reflection groups
2010/12/10
We prove the completeness of the Bethe ansatz eigenfunctions of the Laplacian on a Weyl alcove with repulsive boundary condition at the walls. For the root system of type A this amounts to the result ...
Time Series, Stochastic Processes and Completeness of Quantum Theory

2010/10/20
Most of physical experiments are usually described as repeated measurements of some random variables. Experimental data registered by on-line computers form time series of outcomes. The
frequencies o...
Observational Constraints on the Completeness of Space near Astrophysical Objects
Space near Astrophysical Objects double pulsar
2010/3/18
We consider the observational effects of a deficit angle, w, in the topology of the solar system and in the 'double pulsar' system PSR J0737-3039A/B. Using observations of the perihelion precession of...
A Hypergraph Dictatorship Test with Perfect Completeness
Property testing Gowers norm Fourier analysis PCP
2012/12/3
A hypergraph dictatorship test is first introduced by Samorodnitsky and Trevisan and serves as a key component in their unique games based PCP construction.
Some completeness theorems in the Menger probabilistic metric space
Menger probabilistic metric space
2008/12/26
In this article, some new completeness theorems in probabilis-
tic normed space are proved. Moreover, the existence of a constrictive
Menger probabilistic normed space is shown.
