We present a field-theoretic renormalization group calculation in two loop order for classical O(N)-models with an inverse square interaction in the vicinity of their lower critical dimensionality one. The magnetic susceptibility at low temperatures is shown to diverge like T−a exp(b/T ) with a = (N−2)/(N−1) and b = 2π/(N − 1). From a comparison with the exactly solvable Haldane-Shastry model w...

We prove under certain conditions on a grandcanonical Hamiltonian that at low temperature the pressure is infinitely differentiable with respect to the inverse temperature and other parameters in the Hamiltonian, when the parameters are chosen so that the number of Gibbs states is at least equal to the number of ground states. Applications are made to Antiferromagnets and hard-core gases.

We conducted an ecological study linking prevalence of adult asthma symptoms with climate in the 93 New Zealand general electorates. For each electorate, the 12-month period prevalence of self-reported asthma symptoms was determined using a random sample of adults aged 20-44 on the 1991 New Zealand electoral roll. Long-term average climate was estimated using a national climate database and a g...

There is a general consensus that today's deep-sea biodiversity has largely resulted from recurrent invasions and speciations occurring through homogenous waters during periods of the Phanerozoic eon. Migrations likely continue today, primarily via isothermal water columns, such as those typical of Polar Regions, but the necessary ecological and physiological adaptations behind them are poorly ...

BACKGROUND Numerous studies have reported a strong association between temperature and mortality. Additional insights can be gained from investigating the effects of temperature on years of life lost (YLL), considering the life expectancy at the time of death. OBJECTIVES The goal of this work was to assess the association between temperature and YLL at seven low-, middle-, and high-income sit...

We calculate the low temperature asymptotics of a function γ that generates the temperature dependence of all static correlation functions of the isotropic Heisenberg chain.
