Metastasis on pause: How dormant tumor cells stay hidden within the tumor microenvironment and evade immune surveillance

open access: yesMolecular Oncology, EarlyView.
Dormant cancer cells can hide in distant organs for years, evading treatment and the immune system. This review highlights how signals from the surrounding tissue and immune environment keep these cells inactive or trigger their reawakening. Understanding these mechanisms may help develop therapies to eliminate or control dormant cells and prevent ...

Epsilon-near-zero ITO/Ag/SiO2 metamaterial for large nonlinear absorption

open access: yesEPJ Applied Metamaterials
Enhanced nonlinear optical response contributes to higher device efficiency, lower power consumption and more compact integration. In this study, we designed an epsilon-near-zero multilayer metamaterial composed of Ag, ITO and SiO2.

Fundamental matrix of solutions for one class of parabolic degenerate systems

open access: yesKarpatsʹkì Matematičnì Publìkacìï, 2013
We consider one class of ultraparabolic equation systems of second order, that have three groups of degenerated variables and coefficients of which depend only on a time variable.

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.

The information matrix test with bootstrap-based covariance matrix estimation. [PDF]

open access: yes
We propose an information matrix test in which the covariance matrix of the vector of indicators is estimated using the parametric bootstrap. Monte Carlo results and heuristic arguments show that its small sample performance is comparable with that of ...

Stimulator of interferon genes agonist augmented antitumor immunity of osimertinib in Egfr‐mutated lung cancer

open access: yesMolecular Oncology, EarlyView.
Combining osimertinib with the STING agonist ADU‐S100 activates innate and adaptive immunity to overcome the non‐inflamed microenvironment of Egfr‐mutant lung cancer. This combination increases NK and CD8+ T‐cell infiltration, associated with activation of the STING‐IRF3 pathway and local immunogenic cell death.

Honey, I shrunk the sample covariance matrix [PDF]

open access: yes
The central message of this paper is that nobody should be using the sample covariance matrix for the purpose of portfolio optimization. It contains estimation error of the kind most likely to perturb a mean-variance optimizer.

Fundamental Matrix of a Stereo Pair, with A Contrario Elimination of Outliers

open access: yesImage Processing On Line, 2016
In a stereo image pair, the fundamental matrix encodes the rigidity constraint of the scene. It combines the internal parameters of both cameras (which can be the same) and their relative position and orientation.
