Conserved gravitational charges from Yano tensors
Yano tensor time and space conservation of gravity
2014/12/20
The defining properties of Yano tensors naturally generalize those of Killing vectors to anti-symmetric tensor fields of arbitrary rank. We show how the Yano tensors of flat spacetime can be used to c...
Investigation of symmetries and conserved charges in general relativity
The vector of gravity The black hole mechanics The first law Accelerate the black hole A black hole. Static fixation Bubble time and space
2014/12/9
This thesis presents a series of results relating to conserved charges in general relativity. In particular, we give a general expression for a gravitational charge corresponding to a boost Killing ve...

A Cross-Sectional Analysis of Variation in Charges and Prices across California for Percutaneous Coronary Intervention
A Cross-Sectional Analysis Prices across California
2014/11/7
Though past studies have shown wide variation in aggregate hospital price indices and specific procedures, few have documented or explained such variation for distinct and common episodes of care. We ...
Analysis of variation in charges and prices paid for vaginal and caesarean section births: a cross-sectional study
Analysis of variation vaginal caesarean section births
2014/11/7
This article aims to examine the between-hospital variation of charges and discounted prices for uncomplicated vaginal and caesarean section deliveries, and to determine the institutional and market-l...
An examination of author-paid charges in science journals
examination author-paid charges science journals
2016/3/16
Top-tier journals were examined in terms of the financial contributions of authors, including page charges. Such fees began as early as the 1930s and continue to become more common. A comparison withi...
Taxes And Charges On Nature's Bounties
resource rent tax natural resources economic thought
2011/10/23
The article discusses the controversy and intense national debate of resource rent tax after the National Budget which culminated in the replacement of the Prime Minister in Australia on May 2, 2010. ...
We derive the Noether currents and charges associated with an internal galilean invariance---a symmetry recently postulated in the context of so-called galileon theories. Along the way we clarify the...
Relativistic Hydrodynamics with General Anomalous Charges
Relativistic Hydrodynamics General Anomalous Charges
2010/12/24
We consider the hydrodynamic regime of gauge theories with general triangle anomalies, where the participating currents may be global or gauged, abelian or non-abelian. We generalize the argument of ...

2010/12/15
We perform a nonrelativistic contraction of N-extended Poincar´e superalgebra with internal symmetry U(N) and general set of N(N −1) real central charges.
Axial charges of N(1535) and N(1650) in two-flavor lattice QCD

2009/11/24
We show the lattice QCD results on the axial charge gAN*N* of negative parity nucleon resonances, N*(1535) and N*(1650), which are key clues to the chiral structure in baryon sector. The measurements ...
