The species was described from specimens collected in Algeria, and was later also reported from Belgium, France, Germany, The Netherlands, Spain, and Tunisia (Recalde Irurzun & Pérez-Moreno 2007; Bonamie et al. 2010; Bouyon 2014; Gielen & Smets 2020; Nikitsky 2020; Bleich & Gürlich 2021; Háva 2021; Eisinger in press, all sub Eulagius). It has been imported to Great Britain, where it seems to be established (Harrison 1996; Foster 2001, 2013; Booth 2012; Denton & Dodd 2013; Nikitsky 2020, all sub Eulagius). The biology and ecology of Stereophilus filicornis gen. et comb. nov. are poorly known: some authors report catches from under bark on dead trunks, on woody debris of old trees, and by beating dead branches of broadleaf trees such as Castanea sativa Mill., Quercus canariensis Willd. (= mirbeckii Durieu), Q. robur L., Q. suber L. (Caillol 1925, sub Atritomus; Peyerimhoff 1926, sub Parabaptistes; Labatut et al. 2014, sub Eulagius); only Freeman (2003, sub Parabaptistes) reported a series of specimens reared from carpophores of Stereum hirsutum (Willd.) Pers. (Russulales, Stereaceae), sampled from Fagus sylvatica L. The single specimen here reported from southern Italy, Calabria (Aspromonte) was found by sifting wood mould, woody debris, and Daedaleopsis nitida (Durieu & Mont.) Zmitr. & Malysheva (Polyporales, Polyporaceae) carpophores, likely its local host fungus, collected from inside a large hollow on a Quercus suber trunk. The site is a mesophile cork oak mixed forest, referred to the Helleboro-Quercetum suberis association (Signorello 1984; Mercurio & Spampinato 2001). The habitat of Stereophilus filicornis gen. et comb. nov. in Tuscan sites is represented by fragments of hilly submesophile woodland dominated by Castanea sativa and Quercus cerris L. (Nugola municipality: Bosco Malenchini and Bosco Macchia Grossa) and mosaics of Mediterranean maquis, holm oak and Aleppo pine woods (Antignano and Bellosguardo municipalities) (V. Lazzeri, pers. comm.). Our records are the first of this species for Italy. According to Tempère (1974, sub Parabaptistes), the species could also be present in Sicily. However, no source was provided and the occurrence of Stereophilus filicornis gen. et comb. nov. in Sicily remains unconfirmed.Published as part of Biscaccianti, Alessandro B., Esser, Jens, Cuoco, Silvio, Grimaldi, Enrica Giuliano & Audisio, Paolo A., 2022, West Palaearctic taxa formerly connected to the ' old' genus Atritomus Reitter, 1877 (Coleoptera, Mycetophagidae): taxonomy, distribution, and description of a new genus, pp. 61-74 in European Journal of Taxonomy 828 on pages 65-66, DOI: 10.5852/ejt.2022.828.1853, http://zenodo.org/record/681152
The VIRGO suspensions: Design and recent performance measurements
No full textThe success of the VIRGO interferometer to detect gravitational waves, starting from a few Hz, depends on the ability of its suspension systems to isolate the test masses from seismic noise and to maintain them actively at a working position with relative displacement of ∼ 10-12 m rms on a time scale of several hours. For this purpose, considerable development effort has been dedicated to realize a multi-stage vibration isolator to suspend the test masses: the SuperAttenuator (SA). It has been designed to provide an attenuation of more than 10 orders of magnitude starting from about 4 Hz. Hierarchical control forces, exerted via coil-magnet actuators placed at three different stages of the SA, damp the fundamental mechanical modes of the system (all below 2 Hz) and maintain the relative orientation and position of the test mass for interferometer alignment and locking. In this Letter a description of the SA is given and recent experimental results are presented. © 2003 Elsevier B.V. All rights reserved
Il progetto di decreto per la pubblica istruzione di Vincenzo Cuoco (1809)
No full textIl 27 gennaio 1809 Gioacchino Murat, re di Napoli, nominò una commissione incaricata di redigere un progetto di legge sulla pubblica istruzione.I due documenti prodotti a tale scopo, e cioè Il Progetto di decreto per la pubblica istruzione (1809) e il Rapporto al re Gioacchino Murat (1809) furono sottoscritti dall’intera commissione incaricata. Tuttavia, sulla scia di ricerche e riflessioni condotte in ambito scientifico, si può ritenere che Vincenzo Cuoco ne fosse il reale autore. Il saggio analizza Il Progetto e il Rapporto che lo introduce allo scopo di riflettere su alcuni nodi problematici della visione politica cuochiana. In primo luogo, saranno delineate le principali differenze fra il sistema d’istruzione napoleonico e il testo di Cuoco. Alla luce di tale comparazione saranno poi affrontati due aspetti controversi della visione politica cuochiana: 1) la caratterizzazione del pensiero di Cuoco in chiave democratica o moderata; 2) il rapporto specifico di Cuoco con il riformismo napoleonico francese sul tema dell’istruzione. In ultimo, si proverà a contestualizzare la riedizione del Progetto nella Napoli del 1848, collegandola ai temi e alle modalità della mobilitazione politica napoletana coeva
Evolution of topological superconductivity by orbital-selective confinement in oxide nanowires
No full textWe determine the optimal conditions to achieve topological superconducting phases having spin-singlet pairing for a planar nanowire with a finite lateral width in the presence of an in-plane external magnetic field. We employ a microscopic description that is based on a three-band electronic model including both the atomic spin-orbit coupling and the inversion asymmetric potential at the interface between oxide band-gap insulators. We consider amplitudes of the pairing gap, spin-orbit interactions, and electronic parameters that are directly applicable to nanowires of LaAlO3-SrTiO3. The lateral confinement introduces a splitting of the d orbitals that alters the orbital energy hierarchy and significantly affects the electron filling dependence of the topological phase diagram. Due to the orbital directionality of the t(2g) states, we find that in the regime of strong confinement the onset of topological phases is pinned at electron filling where the quasiflat heavy bands start to get populated. The increase of the nanowire thickness leads to a changeover from a sparse-to-dense distribution of topologically nontrivial domains which occurs at the crossover associated with the orbital population inversion. These findings are corroborated by a detailed analysis of the most favorable topological superconducting phases in the electron doping-magnetic field plane highlighting the role of orbital-selective confinement
Delusion, possession and religion †
No full textBackground: Religion and psychiatry may be both considered to be two different ways of explaining the unknown, of responding to questions about the meaning of life, and of bringing healing. Aims: To discuss the border between religion and psychiatry. Method: This lecture explores the interface between religion and psychiatry and discusses the border between soul and mind. Results: Religious beliefs may affect behaviours and may been seen on a psychopathological continuum with overvalued ideas and delusions. There is an overlap between psychiatric and religious categories, in possession states described in research literature and by many cultural groups. Several studies suggest possible factors for differentiating schizophrenia from demonic influence and report on the efficacy of exorcism among possessed/psychotic subjects. Diagnostic criteria have been proposed for dissociative trance disorder or possession disorder. Conclusions: Both mental health professionals and religious believers may require criteria to distinguish adaptive and maladaptive expressions of religious experience
The endocannabinoid system and its possible role in neurobiology of psychiatric disorders
No full textIn the last years, numerous researches led to identify endocannabinoid system, a sophisticated short-range signaling system which is located both in Central,Nervous System (CNS) and in whole organism. Because of its flexibility of expression, it plays a modulatory role in controlling the answers to stimuli which disturb homeostasis. On one hand it lets them occur whilst on the other it limits them in order to protect organism from consequences due to excessive reaction. In the CNS, endocannabinoid system is able to control the release of several neurotransmitters thanks to its retrograde signaling, modulating synaptic activity. Analysing this property during preclinical studies, it came out that the endocannabinoid system is involved in numerous physiologic processes, such as neuroendocrine axes, food consumption, brain reward and satisfaction mechanisms, memories storing and extinction, emotions and neurodevelopment regulation. Such discoveries have led,researchers to suppose and investigate an alteration of this system in the physiopathology of some psychiatric disorders such as anxiety disorder, depression, eating disorders, addiction and schizophrenia. Results of such studies on animal models show a possible involvement of this system and were quickly followed by clinical studies which seem to confirm it. These findings might open new scenarios for understanding the pathogenesis of several psychiatric disorders and, at same time, they show new prospects for their treatment
A case of shared psychotic disorder (folie à deux) with original aspects associated with cross-cultural elements
No full textShared psychotic disorder (folie à deux) is a rare condition characterized by the transmission of delusional aspects from a patient (the "dominant partner") to another (the "submissive partner") linked to the first by a close relationship. We report the case of two Moroccan sisters who have experienced a combined delusional episode diagnosed as shared psychotic disorder. In these circumstances, assessment of symptoms from a cross-cultural perspective is a key factor for proper diagnostic evaluation
The antiseismic suspension for the VIRGO project
No full textGravitational waves propagating from rapidly accelerating star masses can be detected by means of interferometric techniques. Several interferometric antennas are presently under construction around the world with the aim of gravitational waves detection in the frequency range starting from a few tens of Hz to a few kHz. In the low frequency region (below a few tens of Hz) their detection is limited by seismic noise which can mask the weak signal induced by a gravitational wave impinging on a suspended mirror. In order to overcome this limitation, the VIRGO collaboration has developed and built a sophisticated suspension system to isolate the optical components from the seismic noise. This mechanical system, called SuperAttenuator, is able to inhibit the transmission of any mechanical disturbances starting from about 4 Hz thus extending the detection band in the low frequency region
Fe and As geochemical self-removal dynamics in mineral waters: evidence from the Ferrarelle groundwater system (Riardo Plain, Southern Italy)
No full textA theoretical pattern for Fe and As co-precipitation was tested directly in a groundwater natural system. Several monitoring wells were sampled to identify the different endmembers that govern the hydrodynamics of the Ferrarelle Groundwater System in the Riardo Plain (Southern Italy). In agreement with recent investigations, we found a mix of a deep and a shallow component in different proportions, resulting in a specific chemical composition of groundwater in each well depending on the percentages of each component. The shallow component was characterized by EC ~ 430 μS/cm, Eh ~ 300 mV, Fe ~ 0.06 μmol/L and As ~ 0.01–0.12 μmol/L, while the deep component was characterized by EC ~ 3400 μS/cm, Eh ~ 170 mV, Fe ~ 140 μmol/L and As ~ 0.59 μmol/L. A general attenuation of As and Fe concentration that was not due to a simple dilution effect was observed in the mixing process. The oxidation of Fe(II) to Fe(III) produces solid precipitates which adsorb As from solution and then co-precipitate. The reactions pattern of Fe(II) oxidation and As adsorption gave a linear function between [As] and [Fe], where the angular coefficient depends on the [O2]/[H+] ratio. Chemical data obtained from our samples showed a very good agreement with this theoretical relationship. The investigated geochemical dynamics represented a natural process of attenuation of Fe and As, two undesirable elements that usually affect groundwater quality in volcanic aquifers in central-southern Italy, which are exploited to supply drinking water.
