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 ...

Random Regular Graph States Are Complex at Almost Any Depth

open access: yesPRX Quantum
Graph states are fundamental objects in the theory of quantum information due to their simple classical description and rich entanglement structure. They are also intimately related to instantaneous quantum polynomial-time (IQP) circuits, which have ...

On the Edge-Connectivity of an Uncertain Random Graph

open access: yesIEEE Access, 2020
Connectivity is one of the most important concepts in graph theory. When graph theory is applied to complex systems with indeterminate factors, uncertainty and randomness are two basic types of indeterminacy.

Non symmetric random walk on infinite graph [PDF]

open access: yesOpuscula Mathematica, 2011
We investigate properties of a non symmetric Markov's chain on an infinite graph. We show the connection with matrix valued random walk polynomials which satisfy the orthogonality formula with respect to non a symmetric matrix valued measure.

Subgraphs of random graphs [PDF]

open access: yesTransactions of the American Mathematical Society, 1985
Let Δ ⊆ [ ω ] 2 \Delta \subseteq {[\omega ]^2} be an undirected graph on ω \omega , and let u ∈ [ 0 , 1 ] u \in [0,\,1] . Following P. Erdös and A.

Circulating tumor cell viability during and after radiotherapy mirrors treatment response in cancer patients

open access: yesMolecular Oncology, EarlyView.
Radiotherapy (RT) response depends on the DNA repair capacity of tumor and host cells. We show that circulating tumor cell (CTC) counts and apoptosis rates before and after RT predict treatment response and outcome, which can be accessed via easily accessible liquid biopsy approaches. Created in BioRender. Wikman, H.

Mycobacterial cell division arrest and smooth‐to‐rough envelope transition using CRISPRi‐mediated genetic repression systems

open access: yesFEBS Open Bio, EarlyView.
CRISPRI‐mediated gene silencing and phenotypic exploration in nontuberculous mycobacteria. In this Research Protocol, we describe approaches to control, monitor, and quantitatively assess CRISPRI‐mediated gene silencing in M. smegmatis and M. abscessus model organisms.

Network Motifs: Mean and Variance for the Count

open access: yesRevstat Statistical Journal, 2006
Network motifs are at the core of modern studies on biological networks, trying to encompass global features such as small-world or scale-free properties. Detection of significant motifs may be based on two different approaches: either a comparison with

Treewidth of Erdős–Rényi random graphs, random intersection graphs, and scale-free random graphs

open access: yesDiscrete Applied Mathematics, 2012
We prove that the treewidth of an Erd s-R nyi random graph $\rg{n, m}$ is, with high probability, greater than $ n$ for some constant $ > 0$ if the edge/vertex ratio $\frac{m}{n}$ is greater than 1.073. Our lower bound $\frac{m}{n} > 1.073$ improves the only previously-known lower bound.
