Pseudospectra of semiclassical (pseudo‐) differential operators [PDF]
Communications on Pure and Applied Mathematics, 2003 The authors show how methods from micro-local analysis can be applied to the study of the (pseudo-)spectra of non-selfadjoint operators arising in semiclassical analysis.

Molecular Oncology, EarlyView.This study shows that lung adenocarcinomas exploit developmental branching morphogenesis to acquire a therapy resistant basal‐like tumour cell state. This process was found to be regulated by combined TP53 loss‐of‐function and type‐I interferon signalling, identifying a novel axis for biomarker and therapeutic target discovery.

On the disentanglement of Gaussian quantum states by symplectic rotations
Comptes Rendus. Mathématique, 2020 We show that every Gaussian mixed quantum state can be disentangled by conjugation with a unitary operator corresponding to a symplectic rotation via the metaplectic representation of the symplectic group.

Eigenvalue asymptotics for a class of multi-variable Hankel matrices
Concrete Operators, 2023 A one-variable Hankel matrix Ha{H}_{a} is an infinite matrix Ha=[a(i+j)]i,j≥0{H}_{a}={\left[a\left(i+j)]}_{i,j\ge 0}. Similarly, for any d≥2d\ge 2, a dd-variable Hankel matrix is defined as Ha=[a(i+j)]{H}_{{\bf{a}}}=\left[{\bf{a}}\left({\bf{i}}+{\bf{j}})]

Continuity of Gevrey-Hörmander pseudo-differential operators on modulation spaces
, 2019 Let s ≥ 1, ω,ω ∈ P^0_{E,s} , a ∈ \Gamma _s^(ω_0), and let B be a suitable invariant quasi-Banach function space. Then we prove that the pseudo-differential operator Op(a) is continuous from M(ω_0·ω, B) to M(ω, B).

On a digital approximation for pseudo‐differential operators [PDF]
PAMM, 2017 AbstractWe introduce a concept of a discrete pseudo‐differential operator using general ideas of the theory and would like to show correlations between continuous and discrete cases. (© 2017 Wiley‐VCH Verlag GmbH & Co. KGaA, Weinheim)

Boundedness of Gevrey and Gelfand-Shilov kernels of positive semi-definite operators
, 2015 We show that the strongest Gevrey irregularity of kernels to positive semi-definite operators appear at the diagonals. We also prove that positive elements with respect to the twisted convolution, belonging to a Gevrey class of certain order at the ...

Pseudo-differential operators and regularity of spectral triples
, 2011 We introduce a notion of an algebra of generalized pseudo- differential operators and prove that a spectral triple is regular if and only if it admits an algebra of generalized pseudo-differential operators. We also provide a self-contained proof of the

A Two‐Stage Questionnaire and Actigraphy Screening for iRBD in a Multicenter Retrospective Cohort
Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objective Isolated rapid‐eye‐movement sleep behavior disorder is a prodromal marker of synucleinopathies. However, most cases remain undiagnosed due to the insufficient predictive value of questionnaires and limited access to confirmatory video‐polysomnography. We assessed a two‐stage screening strategy combining a brief questionnaire on rapid‐
