Odd-sunflowers

open access: yesJournal of Combinatorial Theory, Series A, 2023
Extending the notion of sunflowers, we call a family of at least two sets an \emph{odd-sunflower} if every element of the underlying set is contained in an odd number of sets or in none of them. It follows from the Erd\H os--Szemer\'edi conjecture, recently proved by %Alweiss, Lovett, Wu, and Zhang, Naslund and Sawin, that there is a constant $\mu < ...

Odd elasticity [PDF]

open access: yesNature Physics, 2020
Hooke's law states that the forces or stresses experienced by an elastic object are proportional to the applied deformations or strains. The number of coefficients of proportionality between stress and strain, i.e., the elastic moduli, is constrained by energy conservation.

Odd Viscosity and Odd Elasticity

open access: yesAnnual Review of Condensed Matter Physics, 2023
Elasticity typically refers to a material's ability to store energy, whereas viscosity refers to a material's tendency to dissipate it. In this review, we discuss fluids and solids for which this is not the case. These materials display additional linear response coefficients known as odd viscosity and odd elasticity.

An odd characterization of the generalized odd graphs [PDF]

open access: yesJournal of Combinatorial Theory, Series B, 2010
We show that any connected regular graph with $d+1$ distinct eigenvalues and odd-girth $2d+1$ is distance-regular, and in particular that it is a generalized odd graph.

Odd-odd continued fraction algorithm

open access: yesMonatshefte für Mathematik, 2022
AbstractBy using a jump transformation associated to the Romik map, we define a new continued fraction algorithm called odd-odd continued fraction, whose principal convergents are rational numbers of odd denominators and odd numerators. Among others, it is proved that all the best approximating rationals of odd denominators and odd numerators of an ...

Regularized Proportional Odds Models [PDF]

open access: yes, 2011
The proportional odds model is commonly used in regression analysis to predict the outcome for an ordinal response variable. The maximum likelihood approach becomes unstable or even fails in small samples with relatively large number of predictors.

Chances and risks in the development of the smallest villages in Vysočina Region

open access: yesActa Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 2008
Vysočina is the region with highest numbers of the smallest villages in the Czech Republic. The current levels of the infrastructure, conditions of living of the inhabitants and chances for development of the communities were examined by means of a ...
