, 2013 In this paper, we show that the spin-0 gravitons appearing in Horava-Lifshitz gravity without the projectability condition can be eliminated by extending the gauge symmetries of the foliation-preserving diffeomorphisms to include a local U(1) symmetry ...

Nonradial sign changing solutions to Lane Emden equation
, 2016 In this paper we prove the existence of continua of nonradial solutions for the Lane-Emden equation. In a first result we show that there are infinitely many global continua detaching from the curve of radial solutions with any prescribed number of nodal

Higher dimensional Numerical Relativity: code comparison [PDF]
, 2014 The nonlinear behavior of higher dimensional black hole spacetimes is of interest in several contexts, ranging from an understanding of cosmic censorship to black hole production in high-energy collisions.

A note on observational equivalence of micro assumptions on macro level
Economics: Journal Articles, 2020 The author set up a simplistic agent-based model where agents learn with reinforcement observing an incomplete set of variables. The model is employed to generate an artificial dataset that is used to estimate standard macro econometric models.

Horizon-absorption effects in coalescing black-hole binaries: An effective-one-body study of the non-spinning case [PDF]
, 2012 We study the horizon absorption of gravitational waves in coalescing, circularized, nonspinning black hole binaries. The horizon absorbed fluxes of a binary with a large mass ratio (q=1000) obtained by numerical perturbative simulations are compared with

European Journal of Neurology, Volume 33, Issue 3, March 2026.This study analyzes nationwide hospitalization data from Spain to evaluate the clinical and economic impact of restrictive immunoglobulin access in neurological disorders and immunodeficiencies. Using ICD‐10–coded admissions from 2019 and 2022, changes in clinical outcomes and resource use were assessed.

, 2010 Objectives: Resistance (R) of S. pneumoniae (SPN) to fluoroquinolones (FQ) is mainly associated with mutations in the genes parC and gyrA encoding for the ParC subunit of topoisomerase IV and the GyrA subunit of DNA gyrase, respectively. Complete R to anti-pneumococcal FQs such as levofloxacin (LVX)[for full text, please go to the a.m. URL]

Weakly magnetized black holes as particle accelerators
, 2011 We study collision of particles in the vicinity of a horizon of a weakly magnetized non-rotating black hole. In the presence of the magnetic field innermost stable circular orbits (ISCO) of charged particles can be located close to the horizon.

Simulating holographic correspondence in flexible graphene [PDF]
, 2013 In the spirit of the generalized holographic conjecture, we explore a relationship between the bulk and boundary properties of non-interacting massive Dirac fermions living on a flexible surface, such as a sheet of graphene.
