On a degenerate parabolic equation from double phase convection

open access: yesAdvances in Difference Equations, 2021
The initial-boundary value problem of a degenerate parabolic equation arising from double phase convection is considered. Let a ( x ) $a(x)$ and b ( x ) $b(x)$ be the diffusion coefficients corresponding to the double phase respectively.

Trace of depression: Network structure of depressive symptoms in different clinical conditions

open access: yesEuropean Psychiatry, 2022
Background Psychopathological network model has received attention recently in the traditional debate about the continuity of depression. However, there is little evidence for comparing the network structure of depressive symptoms in several depressive ...

Statistical mechanics of a two-dimensional black hole

open access: yesJournal of High Energy Physics, 2019
The dynamics of a nearly-AdS2 spacetime with boundaries is reduced to that of two particles in the anti-de Sitter space. We determine the class of physically meaningful wavefunctions, and prescribe the statistical mechanics of a black hole.

LR-LRU: A PACS-Oriented Intelligent Cache Replacement Policy

open access: yesIEEE Access, 2019
An intelligent cache replacement policy suitable for picture archiving and communication systems (PACS) was proposed in this work. By combining the logistic regression (LR) algorithm with the classic least recently used (LRU) cache replacement policy, we

Quantum Jackiw-Teitelboim gravity, Selberg trace formula, and random matrix theory

open access: yesPhysical Review Research, 2020
We show that the partition function of quantum Jackiw-Teitelboim (JT) gravity, including topological fluctuations, is equivalent to the partition function of a Maass-Laplace operator of large (imaginary) weight acting on noncompact, infinite-area ...

Identifying seasonal mobility profiles from anonymized and aggregated mobile phone data. Application in food security. [PDF]

open access: yesPLoS ONE, 2018
We propose a framework for the systematic analysis of mobile phone data to identify relevant mobility profiles in a population. The proposed framework allows finding distinct human mobility profiles based on the digital trace of mobile phone users ...

Casimir Effect, Achucarro-Ortiz Black Hole and the Cosmological Constant [PDF]

open access: yes, 2003
We treat the two-dimensional Achucarro-Ortiz black hole (also known as (1+1) dilatonic black hole) as a Casimir-type system. The stress tensor of a massless scalar field satisfying Dirichlet boundary conditions on two one-dimensional "walls" ("Dirichlet ...

Rethinking the evidence for early horse domestication at Botai

open access: yesScientific Reports, 2021
Despite its transformative impact on human history, the early domestication of the horse (Equus caballus) remains exceedingly difficult to trace in the archaeological record.

Gauge Theory and a Dirac Operator on a Noncommutative Space

open access: yes, 2006
As a tool to carry out the quantization of gauge theory on a noncommutative space, we present a Dirac operator that behaves as a line element of the canonical noncommutative space.
