Lengths and heights of random walk excursions [PDF]
Discrete Mathematics & Theoretical Computer Science, 2003 Consider a simple symmetric random walk on the line. The parts of the random walk between consecutive returns to the origin are called excursions. The heights and lengths of these excursions can be arranged in decreasing order.

Random walks with barriers [PDF]
Nature Physics, 2011 Restrictions to molecular motion by barriers (membranes) are ubiquitous in porous media, composite materials and biological tissues. A major challenge is to characterize the microstructure of a material or an organism nondestructively using a bulk transport measurement.

Molecular Oncology, EarlyView.We developed a cost‐effective methylation‐specific droplet digital PCR multiplex assay containing tissue‐conserved and tumor‐specific methylation markers. The assay can detect circulating tumor DNA with high accuracy in patients with localized and metastatic colorectal cancer.

A Random Walk with Heavy Flavours
Advances in High Energy Physics, 2013 We focus on evaluating transport coefficients like drag and diffusion of heavy quarks (HQ) passing through quark-gluon plasma using perturbative QCD (pQCD).

Recurrence of random walk traces
, 2005 We show that the edges crossed by a random walk in a network form a recurrent graph a.s. In fact, the same is true when those edges are weighted by the number of crossings.Comment: Published at http://dx.doi.org/10.1214/009117906000000935 in the Annals

LDAcoop: Integrating non‐linear population dynamics into the analysis of clonogenic growth in vitro
Molecular Oncology, EarlyView.Limiting dilution assays (LDAs) quantify clonogenic growth by seeding serial dilutions of cells and scoring wells for colony formation. The fraction of negative wells is plotted against cells seeded and analyzed using the non‐linear modeling of LDAcoop.

RANDOM WALK HYPOTHESIS IN FINANCIAL MARKETS [PDF]
Challenges of the Knowledge Society, 2017 Random walk hypothesis states that the stock market prices do not follow a predictable trajectory, but are simply random. If you are trying to predict a random set of data, one should test for randomness, because, despite the power and complexity of the ...

Random walk centrality for temporal networks
New Journal of Physics, 2014 Nodes can be ranked according to their relative importance within a network. Ranking algorithms based on random walks are particularly useful because they connect topological and diffusive properties of the network. Previous methods based on random walks,

Quantum random walks in optical lattices [PDF]
, 2002 We propose an experimental realization of discrete quantum random walks using neutral atoms trapped in optical lattices. The random walk is taking place in position space and experimental implementation with present day technology --even using existing ...
