Laminar matroids

open access: yesEuropean Journal of Combinatorics, 2017
A laminar family is a collection $\mathscr{A}$ of subsets of a set $E$ such that, for any two intersecting sets, one is contained in the other. For a capacity function $c$ on $\mathscr{A}$, let $\mathscr{I}$ be $\{I:|I\cap A| \leq c(A)\text{ for all $A\in\mathscr{A}$}\}$.

STATISTICAL TESTS FOR SERIAL DEPENDENCE AND LAMINARITY ON RECURRENCE PLOTS [PDF]

open access: yes, 2011
Although recurrence quantification analysis provides useful information about underlying dynamics, it cannot be used to obtain significance levels on its own.

Thin Trees for Laminar Families

open access: yes2023 IEEE 64th Annual Symposium on Foundations of Computer Science (FOCS), 2023
In the laminar-constrained spanning tree problem, the goal is to find a minimum-cost spanning tree which respects upper bounds on the number of times each cut in a given laminar family is crossed. This generalizes the well-studied degree-bounded spanning tree problem, as well as a previously studied setting where a chain of cuts is given.

Microstructure and cross-sectional shape of limb bones in Great Horned Owls and Red-tailed Hawks: how do these features relate to differences in flight and hunting behavior? [PDF]

open access: yesPLoS ONE, 2014
The Red-tailed Hawk and Great Horned Owl are two species of raptor that are similar in body size, diet, and habitat. Both species use their hindlimbs during hunting, but differ in foot morphology, how they approach and immobilize prey, and the average ...

The hydrogen laminar jet [PDF]

open access: yesInternational Journal of Hydrogen Energy, 2010
Numerical and asymptotic methods are used to investigate the structure of the hydrogen jet discharging into a quiescent air atmosphere. The analysis accounts in particular for the variation of the density and transport properties with composition. The Reynolds number of the flow "Rj", based on the initial jet radius "a", the density and viscosity of ...

Stability Analysis of Bitcoin using Recurrence Quantification Analysis

open access: yesChaos Theory and Applications, 2022
Cryptocurrencies are new kinds of electronic currencies based on communication technologies. These currencies have attracted the attention of investors. However, cryptocurrencies are very volatile and unpredictable. For investors, it is very difficult to

Recurrence Quantification Analysis as a Form of Postural Control Assessment: A Systematic Review

open access: yesApplied Sciences, 2023
Human postural control is commonly assessed by center of pressure (CoP) displacement analysis. However, traditional linear parameters do not provide a complete picture of postural control, so a number of nonlinear analyses have been introduced.

Laminar Craya–Curtet jets [PDF]

open access: yesPhysics of Fluids, 2004
This Brief Communication investigates laminar Craya–Curtet flows, formed when a jet with moderately large Reynolds number discharges into a coaxial ducted flow of much larger radius. It is seen that the Craya–Curtet number, C=(Jc/Jj)1/2, defined as the square root of the ratio of the momentum flux of the coflowing stream to that of the central jet ...

Recurrence quantification analysis. [PDF]

open access: yes, 2023
The recurrence rate (RR), determinism (DET), longest diagonal line (LMAX), entropy (ENT), laminarity (LAM) and trapping time (TT) for polyp A, polyp B and polyp C are shown in (a), (b), (c), (d), (e), (f), respectively.
