A macroscopic approach to demography

Journal of Mathematical Biology, 2004
A canonical/lognormal model for human demography is established, specifying the net maternity function and the age distribution for mothers of new-borns using a single macroscopic parameter vector of dimension five. The age distribution of mothers is canonical, while the net maternity function normalizes to a lognormal density.

Conventional macroscopic pretreatment

2015
The recuperation of valuable compounds from food wastes involves initially a stage of macroscopic pre-treatment for the appropriate modification of the material to a form that is adequate for the following stages. Thermal or vacuum concentration, freeze drying, reduction of particle size, centrifugation, mechanical pressing and microfiltration are ...

Macroscopic invisible cables

Microsystem Technologies, 2008
Spiders suggest to us that producing high strength over density ratio invisible cables could be of great importance. In this paper we show that such invisible cables could in principle be built, thanks to carbon nanotube bundles. Theoretical strength of ~10 MPa, Young’s modulus of ~0.1 GPa and density of ~0.1 Kg/m3 are estimated.

Microscopic and macroscopic entropy

Physical Review A, 1988
We consider physical systems in which microstates can be represented as symbol sequences. The internal correlations in a microstate give restrictions to its ``randomness,'' quantified by the measure entropy of that microstate. It is shown that, in the thermodynamic limit, the measure entropy for the microstates has an ensemble average equal to the ...

Casimir effect at macroscopic distances

Physical Review A, 1993
The possibility of observing the Casimir force at macroscopic distances (a few centimeters) using a confocal optical resonator is discussed and a possible experimental apparatus is also ...
