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 $A\in\mathscr{A}$}\}$.

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.

Fine-scale computations for adaptive processing in the human brain

open access: yeseLife, 2020
Adapting to the environment statistics by reducing brain responses to repetitive sensory information is key for efficient information processing. Yet, the fine-scale computations that support this adaptive processing in the human brain remain largely ...

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 ...

Heat Induced Separation in Upward Impinging Jet Flows

open access: yesJournal of Thermal Science and Technology, 2011
A confined, round, laminar impinging jet, fed upward against the gravity, is studied, both experimentally and numerically, under the influence of an impingement-surface heating.

Feedforward and feedback projections of caudal belt and parabelt areas of auditory cortex: refining the hierarchical model

open access: yesFrontiers in Neuroscience, 2014
Our working model of the primate auditory cortex recognizes three major regions (core, belt, parabelt), subdivided into thirteen areas. The connections between areas are topographically ordered in a manner consistent with information flow along two major

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 ...

The Importance of Lamina Size Measurement and Proper Implants Selection before Laminoplasty : Two Case Reports [PDF]

open access: yesKosin Medical Journal, 2021
Open door laminoplasty using plates is a safe and effective procedure for multi-level cord compression. To achieve stable laminar arch, various types of plate have been developed and used.

The Effect of Boundary Air Flow on Premixed Stationary Burning Velocity [PDF]

open access: yesEngineering and Technology Journal, 2009
In this study the effect of boundary condition on premixed methane-airstationary Bunsen flames has been experimentally investigated. Laminar burning velocity is calculated by the concentrated cons method (CCM) and Schlieren photography technique, under ...

Evaluation of Computational Methodologies for Accurate Prediction of Wall Shear Stress and Turbulence Parameters in a Patient-Specific Aorta

open access: yesFrontiers in Bioengineering and Biotechnology, 2022
Background: Recent studies suggest that blood flow in main arteries is intrinsically disturbed, even under healthy conditions. Despite this, many computational fluid dynamics (CFD) analyses of aortic haemodynamics make the assumption of laminar flow, and
