Dissolved carbon dioxide concentration controls baseline stable carbon isotope signatures of a lake food web
Dissolved carbon dioxide concentration controls baseline stable carbon isotope signatures a lake food web
2014/4/3
Temporal variation in the baseline stable carbon isotope (d13C) value of a well-studied, productive lake was examined over a 26-yr period using archived samples of the herbivorous zooplankterDaphnia g...
Facile Enrichment and Photocatalytical Degradation of Low Concentration MB in Aqueous Solution
Absorbent Anatase Titania Attapulgite Decantation Enrichment Photodegradation Simple Separation
2011/11/15
Fine particles of photoactive anatase-type TiO2, prepared by hydrolysis of tetrabutyl orthotitanate and crystallized under microwave (MV) irradiation, were loaded on adsorbent support attapulgite (ATP...
Explicit Bounds for Entropy Concentration under Linear Constraints
maximum entropy concentration bounds linear constraints tolerances
2011/9/23
Abstract: Consider the construction of an object composed of $m$ parts by distributing $n$ units to those parts. For example, say we are assigning $n$ balls to $m$ boxes. Each assignment results in a ...

Conditioned Poisson distributions and the concentration of chromatic numbers
Random graph chromatic number second moment method categorical data twoway tables Poisson counts
2011/10/9
Abstract: The paper provides a simpler method for proving a delicate inequality that was used by Achlioptis and Naor to establish asymptotic concentration for chromatic numbers of Erdos-Renyi random g...
On the concentration properties of Interacting particle processes
Concentration properties Feynman-Kac particle processes stochastic particle models
2011/9/1
Abstract: These lecture notes present some new concentration inequalities for Feynman-Kac particle processes. We analyze different types of stochastic particle models, including particle profile occup...

In response to the Fukushima nuclear reactor accident, on March 20th, 2011,Natural Resources Canada conducted aerial radiation surveys over water just off of the west coast of Vancouver Island. Dose-r...
Concentration of points on Modular Quadratic Forms
modular equation quadratic form concentration of points
2011/2/21
Let Q(x, y) be a quadratic form with discriminant D 6= 0. We obtain non trivial upper
bound estimates for the number of solutions of the congruence Q(x, y) ≡ (mod p), where p is
a prime and x, y l...
Tracer concentration profiles measured in central London as part of the REPARTEE campaign
Tracer concentration central London the REPARTEE campaign
2011/1/19
There have been relatively few tracer experiments carried out that have looked at vertical plume spread in urban areas. In this paper we present results from two tracer (cyclic perfluorocarbon) experi...
Concentration of the information in data with log-concave distributions
Concentration entropy log-concave distributions
2011/2/28
A concentration property of the functional −log f(X) is demonstrated,when a random vector X has a log-concave density f on Rn.This concentration property implies in particular an extension of th...
Ion Concentration Dynamics as a Mechanism for Neuronal Bursting
Ion Concentration Dynamics Mechanism Neuronal Bursting
2011/1/5
We describe a simple conductance-based model neuron that includes intra- and extra-cellular ion concentration dynamics and show that this model exhibits periodic bursting. The bursting arises as the f...
Existence and concentration of solutions for a class of biharmonic equations
Existence and concentration of solutions biharmonic equations
2010/11/22
Some superlinear fourth order elliptic equations are considered. Ground states are proved to exist and to concentrate at a point in the limit. The proof relies on variational methods, where the existe...
Concentration of measure for systems of Brownian particles interacting through their ranks
Concentration of measure Brownian particles
2010/11/17
We consider a finite or countable collection of one-dimensional Brownian particles whose dynamics at any point in time is determined by their rank in the entire particle system. Using Transportation ...
Equivalence of concentration inequalities for linear and non-linear functions
concentration of measure large deviations quasiconvexity
2010/12/13
We consider a random variable X that takes values in a (possibly infinite-dimensional) topological vector space X. We show that, with respect to an appropriate “normal distance” on X.
Concentration on circles for nonlinear Schrödinger-Poisson systems with unbounded potentials vanishing at infinity
Stationary nonlinear Schrö dinger-Poisson system weighted Sobolev spaces
2010/12/6
The present paper is devoted to weighted Nonlinear Schrödinger- Poisson systems with potentials possibly unbounded and vanishing at infinity. Using a purely variational approach, we prove the exi...
