Geometric approximations to transition densities of Jump-type Markov processes

open access: yesOpen Mathematics, 2021
This paper is concerned with the transition functions of symmetric Levy-type processes generated by a pseudo-differential operator with variable coefficients.

Pseudo-differential operators with symbols in modulation spaces

open access: yes, 2010
We establish continuity results for pseudo-differential operators with symbols in modulation spaces, especially for spaces related to classical Wiener amalgam spaces.

A new class of pseudo-differential operators [PDF]

open access: yesProceedings of the National Academy of Sciences, 1978
We describe a class of pseudo-differential operators and their singular integral realizations and show how these may be used to give precise estimates in various function spaces. Application will be given in particular to several situations in which subelliptic estimates arise for partial differential equations.

Ellipticity and Fredholmness of pseudo-differential operators on l(2)(Z(n))

open access: yes, 2021
The minimal operator and the maximal operator of an elliptic pseudo-differential operator with symbols on Z(n) x T-n are proved to coincide and the domain is given in terms of a Sobolev space.

The heterodimeric amino acid transporters (HAT) of the SLC7/SLC3 family: A structure−function relationships and relevance to human pathology

open access: yesFEBS Letters, EarlyView.
Heterodimeric amino acid transporters consist of SLC7 and SLC3 family proteins arranged in a conserved structural organization. They regulate nutrient transport across cell membranes, supporting essential cellular functions. These transporters also contribute to xenobiotic/drug uptake and distribution.

Pseudospectra of semiclassical (pseudo‐) differential operators [PDF]

open access: yesCommunications 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.

Developmental programmes drive cellular plasticity, disease progression and therapy resistance in lung adenocarcinoma

open access: yesMolecular 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.

USP29‐regulated noncanonical stabilization of the hypoxia‐inducible factor‐α in aggressive prostate cancer

open access: yesMolecular Oncology, EarlyView.
We identify USP29 as the only DUB mirroring CA9 expression, a marker of hypoxia and HIF pathway activation associated with PCA aggressiveness. USP29 stabilizes HIF‐1α and HIF‐2α via a noncanonical mechanism that is independent of PHD/pVHL activity yet relies on proteasomal regulation, establishing USP29 as a previously unrecognized regulator of hypoxic
