A remark on universal sigma integrability [PDF]
Proceedings of the American Mathematical Society, 1963 Our purpose is to answer the question of Leader [1, p. 2341, by producing an example of a sigma algebra a of subsets of a set X and a universally a-integrable function f (i.e., ffdu exists for every countably additive set function u on a) which is not measurable with respect to a. We shall show that the sigma algebra a of Borel subsets of the interval [

Shear Effects in Non-Homogeneous Turbulence [PDF]
, 2000 Motivated by recent experimental and numerical results, a simple unifying picture of intermittency in turbulent shear flows is suggested. Integral Structure Functions (ISF), taking into account explicitly the shear intensity, are introduced on ...

An almost-integral universal Vassiliev invariant of knots
, 2002 A `total Chern class' invariant of knots is defined. This is a universal Vassiliev invariant which is integral `on the level of Lie algebras' but it is not expressible as an integer sum of diagrams.

Universality in Phase Transitions for Ultracold Fermionic Atoms [PDF]
, 2005 We describe the gas of ultracold fermionic atoms by a functional integral for atom and molecule fields. The crossover from Bose-Einstein condensation (BEC) to BCS-type superfluidity shows universal features in terms of a concentration parameter for the ...

Estudio psicosocial de la regulación de la natalidad en 100 familias de la clase media
Revista Colombiana de Obstetricia y Ginecología, 1969 El concepto moderno de la medicina se refiere, cada vez más, al hombre dentro de su ambiente y en su personalidad integral, psicofísica. Otro hecho característico de esta época es la preocupación universal por la explosión demográfica.

Smarr integral formula of D-dimensional stationary spacetimes in Einstein-æther–Maxwell theory
Physics Letters B, 2018 Using the Wald formalism, we investigate the thermodynamics of charged black holes in D-dimensional stationary spacetimes with or without rotations in Einstein-æther–Maxwell theory.

Berezinskii-Kosterlitz-Thouless transition in two-dimensional dipole systems [PDF]
, 2010 The superfluid to normal fluid transition of dipolar bosons in two dimensions is studied throughout the whole density range using path integral Monte Carlo simulations and summarized in the phase diagram.

Mixed heavy–light matching in the Universal One-Loop Effective Action
Physics Letters B, 2016 Recently, a general result for evaluating the path integral at one loop was obtained in the form of the Universal One-Loop Effective Action. It may be used to derive effective field theory operators of dimensions up to six, by evaluating the traces of ...
