New Gauss-Bonnet Black Holes with Curvature-Induced Scalarization in Extended Scalar-Tensor Theories. [PDF]
Physical Review Letters, 2017 In the present Letter, we consider a class of extended scalar-tensor-Gauss-Bonnet (ESTGB) theories for which the scalar degree of freedom is excited only in the extreme curvature regime.

A review of multi-objective optimization: Methods and its applications
Cogent Engineering, 2018 Several reviews have been made regarding the methods and application of multi-objective optimization (MOO). There are two methods of MOO that do not require complicated mathematical equations, so the problem becomes simple.

Effective-action model for dynamical scalarization beyond the adiabatic approximation [PDF]
, 2022 In certain scalar-field extensions to general relativity, scalar charges can develop on compact objects in an inspiraling binary -- an effect known as dynamical scalarization. This effect can be modeled using effective-field-theory methods applied to the

Neutron star scalarization with Gauss-Bonnet and Ricci scalar couplings [PDF]
Physical Review D, 2021 Spontaneous scalarization of neutron stars has been extensively studied in the Damour and Esposito-Far\`ese model, in which a scalar field couples to the Ricci scalar or, equivalently, to the trace of the energy-momentum tensor. However, scalarization of

The concept of B-efficient solution in fair multiobjective optimization problems [PDF]
Iranian Journal of Numerical Analysis and Optimization, 2017 A problem that sometimes occurs in multiobjective optimization is the existence of a large set of fairly effcient solutions. Hence, the decision making based on selecting a unique preferred solution is diffcult.

Scalarized Nutty Wormholes [PDF]
Symmetry, 2021 We construct scalarized wormholes with a NUT charge in higher curvature theories. We consider both Einstein-scalar-Gauss-Bonnet and Einstein-scalar-Chern-Simons theories, following Brihaye, Herdeiro and Radu, who recently studied spontaneously scalarised Schwarzschild-NUT solutions.

Strict Benson proper-ε-efficiency in vector optimization with set-valued maps [PDF]
Yugoslav Journal of Operations Research, 2015 In this paper the notion of Strict Benson proper-ε-efficient solution for a vector optimization problem with set-valued maps is introduced. The scalarization theorems and ε-Lagrangian multiplier theorems are established under the assumption of ...

Constraining scalarization in scalar-Gauss-Bonnet gravity through binary pulsars [PDF]
Physical Review D, 2021 In the present paper we derive strong constrains on scalarization in scalar-Gauss-Bonnet (sGB) gravity using observations of pulsars in close binary systems.

SCALAR–SCALAR BOUND STATE IN NONCOMMUTATIVE SPACE [PDF]
Modern Physics Letters A, 2001 Bethe–Salpeter equation in the noncommutative space for a scalar–scalar bound state is considered. It is shown that in the nonrelativistic limit, the effect of spatial noncommutativity appears as if there exists a magnetic dipole moment coupled to each particle.
