Black holes from multiplets of scalar fields in 2+1- and 3+1-dimensions

open access: yes, 2016
We obtain classes of black hole solutions constructed from multiplets of scalar fields in 2+1 / 3+1 dimensions. The multi-component scalars don't undergo a symmetry breaking so that only the isotropic modulus is effective.

Multidimensional Quadrilateral Lattices are Integrable

open access: yes, 1996
The notion of multidimensional quadrilateral lattice is introduced. It is shown that such a lattice is characterized by a system of integrable discrete nonlinear equations. Different useful formulations of the system are given. The geometric construction

A comprehensive exploration of minimum quantity lubrication in machining process

open access: yesJournal of Mechanical Engineering and Sciences
Minimal Quantity Lubrication (MQL) has received a lot of interest in the machining processes because of its potential and environmental benefits. Transitioning from traditional flood cooling technologies to MQL has various advantages, including lower ...

Supersymmetric particle mass measurement with invariant mass correlations

open access: yes, 2009
The kinematic end-point technique for measuring the masses of supersymmetric particles in R-Parity conserving models at hadron colliders is re-examined with a focus on exploiting additional constraints arising from correlations in invariant mass ...

A methodology for the lightweight design of modern transfer machine tools [PDF]

open access: yes, 2018
This paper deals with a modern design approach via finite elements in the definition of the main structural elements (rotary table and working unit) of an innovative family of transfer machine tools. Using the concepts of green design and manufacture, as

Enantioselective Determination of Amphetamine‐Type Stimulants in Environmental Waters Using SPE and CE–MS/MS

open access: yesELECTROPHORESIS, Volume 47, Issue 3, Page 250-260, March 2026.
ABSTRACT The growing concern over drug abuse, particularly involving amphetamine‐type substances (ATS), has led to their monitoring in environmental waters. These chiral compounds, commonly found in river water and wastewater treatment plant (WWTP) effluents, require analytical methods capable of enantiomeric discrimination, as their enantiomers can ...

Design of pulse jet coolant delivery system for minimal quantity lubricant (IP MQL) operation [PDF]

open access: yes, 2012
Minimum quantity lubrication (MQL) machining is one of the promising solutions to the requirement for reducing cutting fluid consumption. The work here describes MQL machining in a range of lubricant consumption of 2.0-2.355ml/s, which is between 10 ...
