On the convergence of the nonlocal nonlinear model to the classical elasticity equation
(Elsevier, 2021-12)We consider a general class of convolution-type nonlocal wave equations modeling bidirectional propagation of nonlinear waves in a continuous medium. In the limit of vanishing nonlocality we study the behavior of solutions ... -
On the density of branching Brownian motion
(Hacettepe University, 2023-02-15)We consider a d-dimensional dyadic branching Brownian motion, and study the density of its support in the region where there is typically exponential growth of particles. Using geometric arguments and an extension of a ... -
On the existence, uniqueness, and stability of periodic waves for the fractional Benjamin–Bona–Mahony equation
(Wiley, 2022-01)The existence, uniqueness, and stability of periodic traveling waves for the fractional Benjamin–Bona–Mahony equation is considered. In our approach, we give sufficient conditions to prove a uniqueness result for the ... -
On the full dispersion Kadomtsev–Petviashvili equations for dispersive elastic waves
(Elsevier, 2022-09)Full dispersive models of water waves, such as the Whitham equation and the full dispersion Kadomtsev–Petviashvili (KP) equation, are interesting from both the physical and mathematical points of view. This paper studies ... -
On the stability of solitary wave solutions for a generalized fractional Benjamin–Bona–Mahony equation
(IOP Publishing, 2022-03-03)In this paper we establish a rigorous spectral stability analysis for solitary waves associated to a generalized fractional Benjamin-Bona-Mahony type equation. Besides the well known smooth and positive solitary wave with ... -
On the volume of the shrinking branching Brownian sausage
(The Institute of Mathematical Statistics and the Bernoulli Society, 2020)The branching Brownian sausage in R-d was defined in [4] similarly to the classical Wiener sausage, as the random subset of R-d scooped out by moving balls of fixed radius with centers following the trajectories of the ... -
On weak feller continuity properties of non-linear filters
(IEEE, 2019)Weak Feller property of controlled and control free Markov chains leads to many desirable properties. In control-free setups this leads to the existence of invariant probability measures for compact spaces and applicability ... -
Optimal survival strategy for branching Brownian motion in a Poissonian trap field
(Institut Henri Poincaré, 2019-11)We study a branching Brownian motion Z with a generic branching law, evolving in R-d, where a field of Poissonian traps is present. Each trap is a ball with constant radius. The traps are hard in the sense that the process ... -
Orbital stability of periodic standing waves for the cubic fractional nonlinear Schrödinger equation
(Elsevier, 2022-12-25)In this paper, the existence and orbital stability of the periodic standing wave solutions for the nonlinear fractional Schrödinger (fNLS) equation with cubic nonlinearity is studied. The existence is determined by using ... -
Overcharging dilaton black holes in (2+1) dimensions to extremality and beyond
(World Scientific Publishing Co Pte Lt, 2020-12)We test whether static charged dilaton black holes in (2 + 1) dimensions can be turned into naked singularities by sending in test particles from infinity. We derive that overcharging is possible and generic for both ... -
Overspinning Kerr-MOG black holes by test fields and the third law of black hole dynamics
(Springer Nature, 2020-01-11)We evaluate the validity of the weak form of the cosmic censorship conjecture and the third law of black hole dynamics for Kerr-MOG black holes interacting with test scalar fields. Ignoring backreaction effects, we first ... -
Partially-observed discrete-time risk-sensitive mean-field games
(IEEE, 2019)We consider in this paper a general class of discrete-time partially-observed mean-field games with Polish state, action, and measurement spaces and with risk-sensitive (exponential) cost functions which capture the ... -
Particle-flow reconstruction and global event description with the CMS detector
(IOP Publishing, 2017-10-06)The CMS apparatus was identified, a few years before the start of the LHC operation at CERN, to feature properties well suited to particle-flow (PF) reconstruction: a highly-segmented tracker, a fine-grained electromagnetic ... -
Performance analysis of relay-assisted NLOS ultraviolet communications over turbulence channels
(IEEE, 2017)Ultraviolet (UV) communication enables non-line-of-sight (NLOS) outdoor wireless connectivity and is particularly desirable for relaxing or eliminating pointing and tracking requirements of infrared links. In the current ... -
Performance of electron reconstruction and selection with the CMS detector in proton-proton collisions at root s=8 TeV

Performance of the CMS Level-1 trigger in proton-proton collisions at √s = 13 TeV
(2020-10)At the start of Run 2 in 2015, the LHC delivered proton-proton collisions at a center-ofmass energy of 13 TeV. During Run 2 (years 2015-2018) the LHC eventually reached a luminosity of 2.1 x 10(34) cm(-2) s(-1), almost ...
