On the degree of rapid decay [PDF]

, 2010
A finitely generated group $\G$ equipped with a word-length is said to satisfy property RD if there are $C, s\geq 0$ such that, for all non-negative integers $n$, we have $\|a\|\leq C (1+n)^s \|a\|_2$ whenever $a\in\C\G$ is supported on elements of ...

The first thirteenth century church in the city of Valencia: Written and graphic documents in relation with the interventions of the twentieth century

EGA, 2014
Since the early twentieth century, the Church of St. John’s Hospital has been the focus of multiple projects and interventions in order to recover its value. Some of these projects have been accomplished while others have remained on paper.

Cerebral Cavernous Malformations and Focal Drug-Resistant Epilepsy: Behind a Quid Pro Quo of Lesion and Epileptogenic Networks. [PDF]

Eur J Neurol
ABSTRACT Background Cerebral cavernous malformations (CCMs) contribute to focal drug‐resistant epilepsy (fDRE), with surgical outcomes varying due to an incomplete understanding of the interplay between CCM‐impacted regions and areas exhibiting ictal or interictal epileptogenicity.

The creation of direct photons during interactions of deuterium nuclei at energies of 13.5 GeV and 27.0 GeV

St. Petersburg Polytechnical University Journal: Physics and Mathematics
In this study, the invariant spectra and nuclear modification factors of direct photons produced in deuteron collisions at energies sqrt{s_{NN}} = 13.5 and 27.0 GeV/nucleon, relevant to the NICA project have been obtained by calculation.
