Statistical mechanics of a two-dimensional black hole
Journal 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.

On a degenerate parabolic equation from double phase convection
Advances 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
European 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 ...

LR-LRU: A PACS-Oriented Intelligent Cache Replacement Policy
IEEE 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
Physical 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]
PLoS 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 ...

Trace Lasso: a trace norm regularization for correlated designs
CoRR, 2011 Using the $\ell_1$-norm to regularize the estimation of the parameter vector of a linear model leads to an unstable estimator when covariates are highly correlated. In this paper, we introduce a new penalty function which takes into account the correlation of the design matrix to stabilize the estimation.

Rethinking the evidence for early horse domestication at Botai
Scientific 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.
