Consistent higher derivative quantum field theory: A model without tachyons and ghosts
(1996-12-01)
We present a higher derivative gauge theory in (2 + 1) dimensions which can have its parameters suitably tuned in order to become a consistent quantum field theory, in the sense that both tachyons and ghosts are absent ...
Unitarity and nonrelativistic potential energy in a higher-order Lorentz symmetry breaking electromagnetic model
(Amer Physical Soc, 2014-12-10)
The Lorentz-violating model proposed by Myers and Pospelov suffers from a higher-derivative pathology due to a dimension-five operator. In particular, its electromagnetic sector exhibits a spectrum which contains, in ...

Model based and model free control of higher order DC DC converters
(Instituto Tecnológico y de Estudios Superiores de Monterrey, 2021-06)
This dissertation is a set of papers published in high impact journals such as IEEE Transactions on Industrial Electronics and MDPI-Power Electronics. The unifying component of all these works is based on data-driven control ...
Higher spin analogs of linearized topologically massive gravity and linearized new massive gravity
(2021-10-15)
We suggest a new spin-4 self-dual model (parity singlet) and a new spin-4 parity doublet in D=2+1. They are of higher order in derivatives and are described by a totally symmetric rank-4 tensor without extra auxiliary ...
LIMITS on THE COUPLING CONSTANT of HIGHER-DERIVATIVE ELECTROMAGNETISM
(World Scientific Publ Co Pte Ltd, 2010-02-10)
We investigate a higher-derivative version of QED constructed by adding to the Maxwell's Lagrangian a term containing second-order derivatives of the electromagnetic potentials. The resulting Lagrangian, besides being gauge ...
A new way for harmonic probing of hysteretic systems through nonlinear smooth operators
(2019-04-15)
This paper proposes a new way to approach hysteresis with the rate-independent property through an analytical response for the non-smooth hysteresis loop using frequency response approximations. The method consists of ...
Inverse probability tilting for moment condition models with missing data
(Oxford Univ Press, 2012-07)
We propose a new inverse probability weighting (IPW) estimator for moment condition models with missing data. Our estimator is easy to implement and compares favourably with existing IPW estimators, including augmented IPW ...
Process modeling toward higher degradation and minimum energy consumption of an electrochemical decontamination of food dye wastewater
(2021-05-01)
This study explores the modeling and optimization of electrochemical influencing parameters on the sunset yellow (SSY) decontamination process by response surface methodology (RSM). Four factors historical data design which ...
