ODD MULTIPERFECT NUMBERS [PDF]
Bulletin of the Australian Mathematical Society, 2012 AbstractA natural number$n$is called multiperfect or$k$-perfect for integer$k\ge 2$if$\sigma (n)=kn$, where$\sigma (n)$is the sum of the positive divisors of$n$. In this paper, we establish a theorem on odd multiperfect numbers analogous to Euler’s theorem on odd perfect numbers.

Odd Viscosity and Odd Elasticity
Annual 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.

Odd Wheels Are Not Odd-distance Graphs [PDF]
Discrete & Computational Geometry, 2020 AbstractAn odd wheel graph is a graph formed by connecting a new vertex to all vertices of an odd cycle. We answer a question of Rosenfeld and Le by showing that odd wheels cannot be drawn in the plane so that the lengths of the edges are odd integers.

H_0 and Odds on Cosmology [PDF]
, 1995 Recent observations by the Hubble Space Telescope of Cepheids in the Virgo cluster imply a Hubble Constant $H_0=80\pm17$\ km/sec/Mpc. We attempt to clarify some issues of interpretation of these results for determining the global cosmological parameters $

Odd-odd continued fraction algorithm
Monatshefte 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 ...

Early-expressed chemokines predict kidney immunopathology in experimental disseminated Candida albicans infections. [PDF]
PLoS ONE, 2009 The mouse intravenous challenge model of Candida albicans infection is widely used to determine aspects of host-fungus interaction. We investigated the production of cytokines in the kidneys and spleen of animals up to 48 h after challenge with virulent ...

Odds of observing the multiverse
, 2010 Eternal inflation predicts our observable universe lies within a bubble (or pocket universe) embedded in a volume of inflating space. The interior of the bubble undergoes inflation and standard cosmology, while the bubble walls expand outward and collide
