Smart antennas cluster year 2000 report

It has been argued that Horava gravity needs to be extended to include terms that mix spatial and time derivatives in order avoid unacceptable violations of Lorentz invariance in the matter sector. In an earlier paper we have shown that including such mixed derivative terms generically leads to 4th instead of 6th order dispersion relations and this could be (naively) interpreted as a threat to renormalizability. We have also argued that power-counting renormalizability is not actually compromised, but instead the simplest power-counting renormalizable model is not unitary. In this paper we consider the Lifshitz scalar as a toy theory and we generalize our analysis to include higher order operators. We show that models which are power-counting renormalizable and unitary do exist. Our results suggest the existence of a new class of theories that can be thought of as Horava gravity with mixed derivative terms

A dataset of acoustic measurements from soundscapes collected worldwide during the COVID-19 pandemic

Political responses to the COVID-19 pandemic led to changes in city soundscapes around the globe. From March to October 2020, a consortium of 261 contributors from 35 countries brought together by the Silent Cities project built a unique soundscape recordings collection to report on local acoustic changes in urban areas. We present this collection here, along with metadata including observational descriptions of the local areas from the contributors, open-source environmental data, open-source confinement levels and calculation of acoustic descriptors. We performed a technical validation of the dataset using statistical models run on a subset of manually annotated soundscapes. Results confirmed the large-scale usability of ecoacoustic indices and automatic sound event recognition in the Silent Cities soundscape collection. We expect this dataset to be useful for research in the multidisciplinary field of environmental sciences

Una benzodiazepina fuori dal coro. Le potenzialità d'abuso del lormetazepem

Le benzodiazepine sono farmaci di largo consumo in molti paesi del mondo tra cui l'Italia. E' noto il loro potenziale di produrre dipendenza ed una delle raccomandazioni delle maggiori linee-guida internazionali sull'uso delle benzodiazepine è di evitare il più possibile l'uso cronico. Un aspetto particolare in crescita è l'uso di benzodiazepine da parte di tossicodipendenti, soprattutto da eroina. Frequentemente nei srvizi delle tossicodipendenze si osservano soggetti con dipendenze miste includenti BZD, tuttavia sono ora anche presenti soggetti dipendenti da sole BZD. Nel presente studio si presentano i dati delle Medicina delle Dipendenze dell'Azienda Ospedaliera di Verona, che evidenziano un emergente problema di abuso legato in particolare al lormetazepam sotto forma di gocce

Umbro Apollonio e l’Archivio della Biennale di Venezia (1948-1972)

In 1948 Rodolfo Pallucchini requested the collaboration of Umbro Apollonio to organize the 24th Venice Biennale. In 1949 the critic became the permanent curator of the Historical Archive of Contemporary Art (The Biennale Archive). First of all Apollonio organized the archival documentation of the Biennale and for this reason he thought of a new project for the library and the archive: to realize it he previously entrusted with the architect Carlo Scarpa and then with BBPR Group. After the great disorders of the 1968 edition, in 1970 Apollonio became Bienniale director. He curated with Dietrich Mahlow the special exhibition «Proposal for an experimental exhibition». On this occasion, a strong dialogue with the public was sought, focusing on issues such as art and society, art and production, analysis of seeing. The result was an exhibition holding arts from historical avant-garde to the most recent researches

Heroin use impairs smoking cessation among Australian prisoners

Background: Prisoners have extremely high rates of smoking with rates 3-4 times higher than the general community. Many prisoners have used heroin. The aims of this study were to investigate the impact of heroin use on smoking cessation and the social determinants of health among prisoners. Methods. Secondary analysis of data from a randomised controlled trial of a multi-component smoking cessation intervention involving 425 Australian male prisoners. Inmates who, prior to imprisonment, used heroin regularly were compared to those who did not use heroin regularly. Self-reported smoking status was validated at baseline and each follow-up by measuring carbon monoxide levels. Readings exceeding 10 ppm were defined as indicating current smoking. Results: Over half (56.5%) of the participants had ever used heroin while 37.7% regularly (daily or almost daily) used heroin in the year prior to entering prison. Prisoners who regularly used heroin had significantly worse social determinants of health and smoking behaviours, including lower educational attainment, more frequent incarceration and earlier initiation into smoking. Prisoners who regularly used heroin also used and injected other drugs significantly more frequently. At 12-month follow-up, the smoking cessation of prisoners who had regularly used heroin was also significantly lower than prisoners who did not regularly use heroin, a finding confirmed by logistic regression. Conclusions: Regular heroin use prior to imprisonment is an important risk factor for unsuccessful attempts to quit smoking among prisoners and is also associated with worse social determinants of health, higher drug use, and worse smoking behaviours. More effective and earlier smoking cessation interventions are required for particularly disadvantaged groups. Trial registration.
