On the Continuity of Reference of the Elements. A Response to Hendry.
chemistry causal theory reference element Dalton
2011/9/7
Robin Hendry has recently argued that although the term ‘element’ has traditionally been used in two different senses, (basic substance and simple substance), there has nonetheless been a continuity o...
Variations in the axisymmetric transport of magnetic elements on the Sun: 1996-2010
Solar and Stellar Astrophysics (astro-ph.SR)
2010/12/27
We measure the axisymmetric transport of magnetic flux on the Sun by cross-correlating narrow strips of data from line-of-sight magnetograms obtained at a 96-minute cadence by the MDI instrument on th...
Extreme Enhancements of r-process Elements in the Cool Metal-Poor Main-Sequence Star SDSS J2357-0052
Solar and Stellar Astrophysics (astro-ph.SR)
2010/12/23
We report the discovery of a cool metal-poor, main-sequence star exhibiting large excesses of r-process elements. This star is one of two newly discovered cool subdwarfs (effective temperatures of 500...
New induction relations for homogeneous functions in Jucys-Murphy elements
New induction relations homogeneous functions Jucys-Murphy elements
2010/11/26
The problem of computing the class expansion of some symmetric function evaluated in Jucys-Murphy elements appears in different contexts, for instance in the computation of matrix integrals.
Neuromorphic, Digital and Quantum Computation with Memory Circuit Elements
Memory, Resistance Capacitance Inductance Dynamic response Hysteresis
2010/10/27
Memory effects are ubiquitous in nature and the class of memory circuit elements - which includes memristors,memcapacitors and meminductors - shows great potential to understand and simulate the assoc...
Non-trivial elements in the Abel-Jacobi kernels of higher dimensional varieties
algebraic cycles Chow motives Hodge filtration intermediate Jacobian
2010/12/1
The purpose of this paper is to construct new non-trivial elements in the kernels of the Abel-Jacobi maps from the Chow groups of codimension p algebraic cycles to the p-th intermediate Jacobians on h...
Two refreshing views of Fluctuation Theorems through Kinematics Elements and Exponential Martingale
Non-equilibrium Markovian Process Fluctuation-Dissipation Theorems Fluctuation Relations Martingale
2010/12/15
In the context of Markovian evolution, we present two original approaches to obtain Generalized Fluctuation-Dissipation Theorems (GFDT), by using the language of stochastic derivatives and by using a ...
Jucys-Murphy elements for partition algebras
Partition algebras Jucys–Murphy elements central elements presentation
2010/12/3
An inductive formula is given for a family of elements which are shown to play a role in the partition algebras which is analogous to that played by classical Jucys–Murphy elements in the group algebr...
Modular and lower-modular elements of lattices of semigroup varieties
Semigroup variety lattice of varieties commutative variety
2010/12/3
The paper contains three main results. First, we show that if a commutative semigroup variety is a modular element of the lattice Com of all commutative semigroup varieties then it is either the varie...
We present a method to determine Frobenius elements in arbitrary Galois extensions of global fields, which may be seen as a generalisation of Euler’s criterion. It is a part of the general question ho...
A translation: "Every" finite free resolution is a free resolution of an ideal generated by three elements
"Every" finite free free resolution ideal three elements
2011/2/28
In [4] and [7], Burch and Kohn proved that when R is a commutative Noetherian ring, and n a natural number that is the homological dimension 3 of a torsionless R-module, then there exists an ideal in ...

In an effort to understand and quantify the impact of local, regional, and far-distant atmospheric mercury sources to rainfall mercury deposition in the Pensacola, Florida watershed, a program of even...
Statistical Analysis of Rice Samples for Compositions of Multiple Light Elements (H, C, N, and O) and Their Stable Isotopes
Rice Samples Compositions of Multiple Light Elements
2010/9/15
Stable isotopic compositions and elemental contents of the H, C, N, and O in 163 rice samples were analyzed. The samples were taken from three different farming countries; Japan (n = 103), United Stat...
