Enhanced detection of terrestrial gamma-ray flashes by AGILE
2015
Abstract At the end of March 2015 the onboard software configuration of the Astrorivelatore Gamma a Immagini Leggero (AGILE) satellite was modified in order to disable the veto signal of the anticoincidence shield for the minicalorimeter instrument. The motivation for such a change was the understanding that the dead time induced by the anticoincidence prevented the detection of a large fraction of Terrestrial Gamma‐Ray Flashes (TGFs). The configuration change was highly successful resulting in an increase of one order of magnitude in TGF detection rate. As expected, the largest fraction of the new events has short duration (<100 μs), and part of them has simultaneous association with light…
Terranovam natale meum solum : remarks on the textual history of Poggio Bracciolini’s Historiae Florentini populi
2007
Poggio Bracciolini’s last work, the Historiae Florentini populi, was edited and dedicated to Federico di Montefeltro by Jacopo di Poggio in 1472. Jacopo also translated the work into the volgare and had it printed in Venice in 1476. In the light of the manuscript tradition, Jacopo’s editorial changes were more considerable than has hitherto been thought. The propagation of his edition and translation would seem to be intimately connected with his political aspirations ending in his unfortunate participation in the Pazzi conspiracy of 1478. peerReviewed

Rockefeller Philanthropy and Mathematical Emigration between World Wars
2015
Published version of an article in the journal: The Mathematical Intelligencer. Also available from the publisher at: http://dx.doi.org/10.1007/s00283-014-9530-9 This article discusses one aspect of Rockefeller support for mathematics: the emigration of mathematicians from Europe. For the broader policies of the Rockefeller philanthropies for internationalization of mathematics, see my monograph Siegmund-Schultze (2001), which together with other sources will be broadly used in the following and will be quoted as RI.
A quoi sert une prison au XVIIIe siècle ? L'exemple des prisons patrimoniales de Beaune (1783-1790)
2015
Benoît Garnot Sous l'Ancien Régime, la prison joue dans le système pénal un rôle très différent de celui qu'elle assume depuis la Révolution. En théorie, l'enfermement en prison ne fait pas partie de l'arsenal des peines, même s'il y a des exceptions, en particulier pour les femmes, comme substitution aux peines de galère, ainsi que pour les vieillards. La prison est d'abord (et surtout) le lieu où se trouvent détenus les débiteurs récalcitrants. Elle se trouve aussi utilisée à titre préventi...
Emigration of mathematicians from outside German-speaking academia 1933-1963, supported by the Society for the Protection of Science and Learning
2012
Author's version of an article published in the journal: Historia Mathematica. Also available from the publisher at: http://dx.doi.org/10.1016/j.hm.2011.08.002 Racial and political persecution of German-speaking scholars from 1933 onward has already been extensively studied. The archives of the Society for the Protection of Science and Learning (SPSL), which are deposited in the Western Manuscripts Collection at the Bodleian Library in Oxford, is a rich source of information about the emigration of European scientists, also those who did not come from German-speaking institutions. This is an account of the support given by the SPSL to the persecuted mathematicians among them. The challenges…

On the thermal instability in a horizontal rectangular porous channel heated from below by a constant flux
2014
Published version of an article in the journal: Journal of Physics: Conference Series. Also available from the publisher at: http://dx.doi.org/10.1088/1742-6596/501/1/012003 Open Access The onset of thermoconvective instability in a rectangular horizontal channel filled with a fluid-saturated porous medium is studied. The channel is heated from below with a constant flux. The top wall is maintained at a uniform constant temperature, while the lateral boundaries are permeable and perfectly conducting. The stability of the basic motionless state is analysed with respect to small-amplitude disturbances. The eigenvalue problem for the neutral stability condition is solved analytically for the n…
Werewolves and warning signs: Cultural responses to tropical cyclones in Mauritius
2022
The role that culture plays in the way different groups experience, respond to, and recover from disasters has been widely discussed. Yet, while there is a considerable (and growing) literature of case study evidence for the need to account for culture in disasters, comparatively few studies take a long-term perspective on cultural interactions with disasters, resulting in a lack of exploration into the diachronic nature of these cultural responses, both past and present. The literature that does exist tends also to focus either on western cultures or on groups that pursue highly traditional livelihoods. Communities that call on elements of both local or vernacular knowledge and scientific …
Work-life balance during the COVID-19 outbreak: the case of Latvia
2020
This paper aims to shed light on work-life balance in Latvia during the state of emergency The COVID-19 outbreak has led many governments to introduce lockdowns While imposed restrictions may help to contain the spread of the virus, they may also result in substantial damage to population well-being The COVID-19 outbreak in Latvia demonstrates the extent and ways in which socio-demographics factors have determined different patterns of behaviour, attitudes, employment changes and harmonised work and life balance The study describes the chronological development of COVID-19 in the country It describes labour migration to and from Latvia before the COVID-19 outbreak It provides geographical f…
