Lattice gas models derived from effective field theory

We start from a low-energy effective field theory for interacting fermions on the lattice and expand in the hopping parameter to derive the nearest-neighbor interactions for a lattice gas model. In this model the renormalization of couplings for different lattice spacings is inherited from the effective field theory, systematic errors can be estimated a priori, and the breakdown of the lattice gas model description at low temperatures can be understood quantitatively. We apply the lattice gas method to neutron matter and compare with results from a recent quantum simulation.Comment: 13 pages, 4 figure

Which older women could benefit from interventions to decrease sitting time and increase physical activity? [Letter to the Editor]

In addition to the well-known health risks associated with lack of physical activity (PA), evidence is emerging about the health risks of sedentary behaviour (sitting). Research about patterns and correlates of sitting and PA in older women is scarce. METHODS: Self-report data from 6,116 women aged 76-81 years were collected as part of the Australian Longitudinal Study on Woman’s Health. Linear regression models were computed to examine whether demographic, social and health factors were associated with sitting and PA. RESULTS: Women who did no PA sat more than women who did any PA (p<0.001). Seven correlates were associated with sitting and PA (p<0.05). Five of these were associated with more sitting and less PA: three health-related (BMI, chronic conditions, anxiety/depression) and two social correlates (caring duties, volunteering). One demographic (being from another English-speaking country) and one social correlate (more social interaction) were associated with more sitting and more PA. Four correlates, two demographic (living in a city; post-high school education), one social (being single), and one health-related correlate (dizziness/loss of balance) were associated with more sitting only. Two other health-related correlates (stiff/painful joints; feet problems) were associated with less PA only. CONCLUSION: Sedentary behaviour and PA are distinct behaviours in older Australian women. Information about the correlates of both behaviours can be used to identify population groups who might benefit from interventions to reduce sedentary behaviour and/or increase PA

Grannies get physical: how bodybuilding may hold the key to a major ageing problem

First paragraph: People have used bodybuilding to improve their physical performance for at least 1,500 years. The first recorded example was the sixth-century wrestler, Milo of Croton, in southern Italy. Milo reportedly carried out his daily exercises with a calf on his back. As the calf grew into a full sized ox, so too did Milo&rsquo;s legendary strength.

Hope for the New Year: getting fitter boosts even the survival of the fattest

First paragraph: Like many high school students I completely misunderstood the philosopher Herbert Spencer&rsquo;s phrase &ldquo;survival of the fittest.&rdquo; I interpreted it to mean that those animals of a species that were the most physically fit were most likely to survive and reproduce. What Spencer was actually proposing when he first coined the phrase in 1864 to explain Darwin&rsquo;s theory of natural selection was that those organisms that best &ldquo;fit&rdquo; their environment are the most likely to survive and reproduce.
