Semiclassical S-matrix theory. VI. Integral expression and transformation of conventional coordinates [PDF]

, 1973
Sometimes, as in reactive systems, action‐angle variables are not conveniently defined at all points of the trajectory and recourse must be made to conventional coordinates.

Harmonic coordinates in the string and membrane equations

, 2010
In this note, we first show that the solutions to Cauchy problems for two versions of relativistic string and membrane equations are diffeomorphic. Then we investigate the coordinates transformation presented in Ref. [9] (see (2.20) in Ref.

Buchdahl-like transformations for perfect fluid spheres

, 2007
In two previous articles [Phys. Rev. D71 (2005) 124307 (gr-qc/0503007), and gr-qc/0607001] we have discussed several "algorithmic" techniques that permit one (in a purely mechanical way) to generate large classes of general relativistic static perfect ...

Applying transformation parameters for 3D transformation between systems WGS 84 and RES (B) [PDF]

Acta Montanistica Slovaca, 2001
Coordinate transformation between 3D cartesian systems: the Reference Elipsoidical System for Bessel’s Ellipsoid - RES(B) (with coordinates C R(B)), and the World geodetic system – WGS 84 (with coordinates C w) are used for transformations C W→ C R(

Vaidya Spacetime in the Diagonal Coordinates

, 2017
We have analyzed the transformation from initial coordinates $(v,r)$ of the Vaidya metric with light coordinate $v$ to the most physical diagonal coordinates $(t,r)$.

Multiinstantons in curvilinear coordinates [PDF]

, 1999
The 'tHooft's 5N-parametric multiinstanton solution is generalized to curvilinear coordinates. Expressions can be simplified by a gauge transformation that makes $\eta$-symbols constant in the vierbein formalism.

Dexamethasone for Chemotherapy‐Induced Nausea and Vomiting Prevention in Pediatric Patients: International Consensus

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background An international Delphi panel of experts developed consensus statements to delineate the circumstances where the risks of dexamethasone as an antiemetic do and do not outweigh its benefits. Procedure Experts in supportive care of pediatric patients were invited to participate.

Kerr metric, static observers and Fermi coordinates

, 2005
The coordinate transformation which maps the Kerr metric written in standard Boyer-Lindquist coordinates to its corresponding form adapted to the natural local coordinates of an observer at rest at a fixed position in the equatorial plane, i.e., Fermi ...

Adherence to Protocol Recommendations for Children With Wilms Tumour in Two Consecutive Studies in the United Kingdom and Ireland—Does Variation Matter?

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background and Aims Wilms tumour (WT) has excellent event‐free and overall survival (OS). However, small differences exist between countries participating in the same international study. This led us to examine variation in adherence to protocol recommendations as a potential contributing factor.

A methodology for transformation between geodetic datums used in Syria

Journal of King Saud University: Engineering Sciences
The Global Navigation Satellite System (GNSS) provides geodetic coordinates referenced to the world ellipsoid WGS84, whereas positions are computed on the local ellipsoid adopted for geodetic computation in various countries.
