On the asymptotic events of a Markov chain

International Journal of Mathematics and Mathematical Sciences, 1979
In this paper we investigate some structure properties of the tail σ-field and the invariant σ-field of both homogeneous and nonhomogeneous Markov chains as representations for asymptotic events, descriptions of completely nonatomic and atomic sets and ...

Statistical field theory and effective action method for scalar active matter

Physical Review Research, 2020
We employ statistical field theory techniques for coarse graining the steady-state properties of active Ornstein-Uhlenbeck particles. The computation is carried out in the framework of the unified colored noise approximation that allows an effective ...

Accretion Disks and Dynamos: Toward a Unified Mean Field Theory

, 2012
Conversion of gravitational energy into radiation in accretion discs and the origin of large scale magnetic fields in astrophysical rotators have often been distinct topics of research. In semi-analytic work on both problems it has been useful to presume

Stereotactic Body Radiation Therapy for Pediatric, Adolescent, and Young Adult Patients With Osteosarcoma: Local Control Outcomes With Dosimetric Analysis

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background/Objectives Osteosarcoma is a radioresistant tumor that may benefit from stereotactic body radiation therapy (SBRT) for locoregional control in metastatic/recurrent disease. We report institutional practice patterns, outcomes, toxicity, and failures in osteosarcoma patients treated with SBRT.

Kaluza–Klein reduction on a maximally non-Riemannian space is moduli-free

Physics Letters B, 2019
We propose a novel Kaluza–Klein scheme which assumes the internal space to be maximally non-Riemannian, meaning that no Riemannian metric can be defined for any subspace.

A New Unified Theory of Electromagnetic and Gravitational Interactions

, 2016
In this paper we present a new unified theory of electromagnetic and gravitational interactions. By considering a four-dimensional spacetime as a hypersurface embedded in a five-dimensional bulk spacetime, we derive the complete set of field equations in

Predicting Chronicity in Children and Adolescents With Newly Diagnosed Immune Thrombocytopenia at the Timepoint of Diagnosis Using Machine Learning‐Based Approaches

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Objectives To identify predictors of chronic ITP (cITP) and to develop a model based on several machine learning (ML) methods to estimate the individual risk of chronicity at the timepoint of diagnosis. Methods We analyzed a longitudinal cohort of 944 children enrolled in the Intercontinental Cooperative immune thrombocytopenia (ITP) Study ...

Holomorphic unified field theory of gravity and the standard model

European Physical Journal C: Particles and Fields
We present a single holomorphic framework in which gravity, all Standard Model interactions, and their couplings to charges and currents emerge from one geometric action on a four-complex dimensional manifold.

On the Propagation of Gravitational Waves in the Weyl Invariant Theory of Gravity

Universe
We revisit Weyl’s unified field theory, which arose in 1918, shortly after general relativity was discovered. As is well known, in order to extend the program of the geometrization of physics started by Einstein to include the electromagnetic field, H ...

SpinUpFlowDescriptor: A MATLAB toolbox for ferrofluids materials under moderate and high amplitude and frequency of magnetic rotating fields in a spin-up geometry

SoftwareX, 2020
There is currently no unified theory for describing ferrofluid flow under a rotating magnetic field. Spin diffusion theory has been broadly studied. But it has been limited to scenarios of magnetic fields with low intensity, due to the approximations ...
