ABSTRACT Only recently the under‐ice period is recognised as a time of plankton activity. However, most studies on under‐ice zooplankton focus on low‐land lakes over relatively short temporal scales; long‐term under‐ice zooplankton dynamics in mountain lakes remain largely unknown. We compared the under‐ice zooplankton community (one sampling per year;

La tradición matemática –en este caso geométrica- se explicita en la construcción de un círculo tangente a tres círculos dados sobre el plano. De la pléyade de geómetras que la intentan hemos tomado sólo a tres.

Strong Under‐Ice Heating of Central Asian Shallow Lakes
Abstract Shallow lakes (<2 m depth) of Central Asian, receiving strong solar radiation and low precipitation, are sensitive to atmospheric forcing because of their low heat capacity, yet their under‐ice thermal conditions remain poorly investigated.

ABSTRACT Extreme meteorological events such as storms are increasing in frequency and intensity, but our knowledge of their impacts on aquatic ecosystems and emergent system properties is limited. Understanding the ecological impacts of storms on the dynamics of primary producers remains a challenge that needs to be addressed to assess the ...

Transition from wave turbulence to dynamical crumpling in vibrated elastic plates
We study the dynamical regime of wave turbulence of a vibrated thin elastic plate based on experimental and numerical observations. We focus our study to the strongly non linear regime described in a previous letter by N. Yokoyama & M. Takaoka.

Spiral-Logarithmic Structure in a Heisenberg Ferromagnet
Spiral-logarithmic structure is suggested as a stationary solution of a modified equation for the Heisenberg model, and the single- and N-soliton solutions are constructed on this base.Comment: LaTeX, 5 pages, no ...

Lift force due to odd (Hall) viscosity
We study the problem of flow of a neutral gas past an infinite cylinder at right angle to its axis at low Reynolds number when the fluid is characterized by broken time-reversal invariance, and hence by odd viscosity in addition to the normal even one ...

Slow flows of an relativistic perfect fluid in a static gravitational field
Relativistic hydrodynamics of an isentropic fluid in a gravitational field is considered as the particular example from the family of Lagrangian hydrodynamic-type systems which possess an infinite set of integrals of motion due to the symmetry of ...

We show that the Conway polynomials of Fibonacci links are Fibonacci polynomials modulo 2. We deduce that, when $ n \not\equiv 0 \Mod 4$ and $(n,j) \neq (3,3),$ the Fibonacci knot $ \cF_j^{(n)} $ is not a Lissajous knot.Comment: 7p ...
