On the out of equilibrium order parameters in long-range spin-glases
We show that the dynamical order parameters can be reexpressed in terms of
the distribution of the staggered auto-correlation and response functions. We
calculate these distributions for the out of equilibrium dynamics of the
Sherrington-Kirpatrick model at long times. The results suggest that the
landscape this model visits at different long times in an out of equilibrium
relaxation process is, in a sense, self-similar. Furthermore, there is a
similarity between the landscape seen out of equilibrium at long times and the
equilibrium landscape. The calculation is greatly simplified by making use of
the superspace notation in the dynamical approach. This notation also
highlights the rather mysterious formal connection between the dynamical and
replica approaches.Comment: 25 pages, Univ. di Roma I preprint #1049 (we replaced the file by the

Potential applications of electron emission membranes in medicine
With a miniaturised stack of transmission dynodes, a noise free amplifier is being developed for the detection of single free electrons, with excellent time- and 2D spatial resolution and efficiency. With this generic technology, a new family of detectors for individual elementary particles may become possible. Potential applications of such electron emission membranes in medicine are discussed
Comment on the letter of the Society of Vertebrate Paleontology (SVP) dated April 21, 2020 regarding \u201cFossils from conflict zones and reproducibility of fossil-based scientific data\u201d: Myanmar amber
Here,
we consider different aspects of the suggestions by Rayfield
et al. (2020) in which we see weaknesses and dangers. It is
our intent to compile views from many different fields of
palaeontology, as our discipline is (and should remain) pluralistic.
This contribution deals with the aspects concerning
