The first resonance frequency is a key performance characteristic of MEMS vibrometers. In batch fabrication, this first resonance frequency can exhibit scatter owing to various sources of manufacturing variability involved in the fabrication process. The aim of this work is to develop a stochastic multiscale model for predicting the first resonance frequency of MEMS microbeams constituted of polycrystals while accounting for the uncertainties in the microstructure due to the grain orientations. At the finest scale, we model the microstructure of polycrystaline materials using a random Voronoï tessellation, each grain being assigned a random orientation. Then, we apply a computational homogenization procedure on statistical volume elements to obtain a stochastic characterization of the elasticity tensor at the second scale of interest, the meso-scale. In the future, using a stochastic finite element method, we will propagate these meso-scale uncertainties to the first resonance frequency at the coarser scale. [less ▲]

The aim of the study was to validate the use of electromyography (EMG) for detecting responses to command in patients in vegetative state/unresponsive wakefulness syndrome (VS/UWS) or in minimally conscious state (MCS). Methods: Thirty-eight patients were included in the study (23 traumatic, 25 patients >1 year post-onset), 10 diagnosed as being in VS/UWS, eight in MCS- (no response to command) and 20 in MCS+ (response to command). Eighteen age-matched controls participated in the experiment. The paradigm consisted of three commands (i.e. 'Move your hands', 'Move your legs' and 'Clench your teeth') and one control sentence (i.e. 'It is a sunny day') presented in random order. Each auditory stimulus was repeated 4-times within one block with a stimulus-onset asynchrony of 30 seconds. Results: Post-hoc analyses with Bonferroni correction revealed that EMG activity was higher solely for the target command in one patient in permanent VS/UWS and in three patients in MCS+. Conclusion: The use of EMG could help clinicians to detect conscious patients who do not show any volitional response during standard behavioural assessments. However, further investigations should determine the sensitivity of EMG as compared to neuroimaging and electrophysiological assessments. [less ▲]

One of the major changes identified as characteristic of Hellenistic religion is the introduction of new cults, and notably cultic honours for mortal rulers. Hellenistic poleis displayed various expedients to integrate these newcomers within their civic and religious landscape, operating a balanced dialectic between innovation and tradition. This integration happened at several levels, whether from a topographic point of view - e.g. consecration of a temenos, installation of altars, statues in sanctuaries of other gods (Schmidt-Dounas 1995) - or through ritual practice - e.g. the foundation of sacrifices and festivals, that were sometimes “appended” to a pre-existing festival (Buraselis 2012). The decree from Teos founding the cult of Antiochos III and Laodike exemplifies with great detail how a ruler cult could be integrated within a civic pantheon and how it echoed other cults (Chaniotis 2007). Based on a few selected inscriptions, this paper will explore some interactions between rulers and local gods as noted in ritual practice. A newly-published inscription from Aigai in Aiolis (EA 42 [2009], 32-60), regulating the foundation of honours for Seleukos I and Antiochos I after their victory over Lysimachos in 281 BC, exemplifies some of these interactions. The decree refers explicitly to Apollo, one of the main god of Aigai, regarding both the localization of the temenos of the kings next to the sanctuary of the god, and also sacrificial regulations, which were modelled after the sacrifices to Apollo. Other cultic associations with a goddess named Sôteira and Zeus Sôter echoed the epithet given to the kings and emphasised the circumstances that led to the introduction of their cult. Further lines of enquiry include the associations with traditional gods of the civic pantheon in prayers and sacrifices that are performed in honour of the king, thus placing the latter in an intermediary position between the polis and the gods. This is the case of an inscription from Ilion (I.Ilion 32), associating a king Antiochos with Athena Ilias on the one hand, Apollo, Zeus and Nike on the other hand, in a dialectic similar to the one observed at Aigai. Although the nature of ritual performance is not very informative as regards the specificity of ruler cult – in so far as it little differed from traditional rituals (Wikander 2005) – the interactions with the gods of the civic pantheon within ritual practice is nonetheless interesting to explore from the point of view of the integration of these new cults. Indeed, although the “practicalities of ruler cult” are not per se very specific, the mechanisms put in place by the poleis may differ in so far as they correspond to a local, specific, context.

« You know where this comes from, shaking hands? It was a way of showing a stranger you weren't carrying a weapon in the old days. » Contagion, Steven Soderbergh, 2011 For decades film directors, inspired by numerous novelists, have exploited the epidemic in various ways: as a general historical context to tell another story (Isle of the Dead, Robson, 1945), as a medical topic at the heart of an investigation (Medical Investigation, Horwitch, 2004), or as a process allowing the proliferation of zombies (Resident Evil, Anderson, 2000) or even vampires (Daybreakers, Spierig, 2010). This work aims at theorising a fascinating and surprising topic – which goes as far as haunting public restrooms with the “Stop Germs: Wash Your Hands” signs – and to offer an overview of films that are very present on our screens and yet absent from scholarly works about cinema. By combining the analysis of photography with that of narrative, this research tries to address issues which may seem, at first sight, plain and transparent (showing the epidemic is showing contaminated individuals) but prove to be, in practice, much more complex (how can contamination be represented since this microscopic phenomenon is invisible to the eye?). The developed method leans on science and the ties between epidemic, contagion and contamination in order to establish an approach going from the more general (epidemic, which belongs to the global and is illustrated as far as the film’s synopsis) to the more particular (contamination, which falls under the interpersonal and is represented only in precise sequence of the film). Beyond questions about cinema or narrative in the strict sense, this final dissertation aims at exploring the other side of epidemic: the collective imaginary it creates. Indeed, the way cinema represents these phenomena indicates a certain conception of epidemic, which spreads from a film to the other, from a viewer to the other. [less ▲]

Although mobility management by employers is an increasingly common practice, literature is scarce on the real impact of the applied measures. In this perspective, the objective of this paper is to assess the impact on car use of the measures adopted by employers located in Wallonia. In order to achieve this objective, the article develops simulations that put forward the impact of the measures based on their interrelations with other modal choice factors. Our assessment leads to the conclusion that measures promoting public transport and car-pooling can reduce solo car driving between 7,2 % and 8,4 %. In contrast to our assumption, measures promoting public transport are less effective in central areas than in urban outskirts. Regarding measures promoting the use of bicycle, the findings suggest that the modal shift occurs from other modes rather than from car use. [less ▲]

In Belgium, as generally in Europe, the dominant position of the high producing commercial strains specialized in meat or eggs production threats of extinction the local traditional breeds. In this work, a follow up of the changes in populations size, and the rates of inbreeding of the Belgian poultry breeds, has been carried out in 2005 and 2010. About forty breeds were concerned. The Belgian hen breeds being overwhelmingly under threat of extinction, because of the low number of individuals by breed. For each of these breeds, various criteria were considered, risk status, breeding male to breeding female ratio, effective population size, effective population size to actual size ratio and rate of inbreeding.

Body size is influenced by the interaction of multiple forces, whose effects can determine the occurrence of sexual size dimorphism (SSD). Rensch's rule is the increase of SSD with body size in taxa where males are the largest sex, and the opposite pattern in female-biased SSD taxa. This pattern was detected in many animal groups, but contrasting results were also highlighted. This study evaluated the existence of Rensch's patterns for body size and for the number of caudal vertebrae in salamandrid caudate amphibians. Furthermore, we tested the support of alternative hypotheses on processes that may determine allometric patterns: sexual selection, fecundity selection and constraining selection by performing separate analyses on species with male- and female-biased SSD. We used the literature and original data to gather information on body size and number of caudal vertebrae in 52 species of salamandrids over four continents. We then tested the support of the three hypotheses using a phylogenetic approach. Rensch's rule was valid for body size in salamanders only for species with male-biased dimorphism. No allometric relationships were detected by analyses on all the species, or by analyses on female-biased SSD species. Analyses performed on the number of caudal vertebrae showed no significant patterns. Our study supports the role of sexual selection in promoting positive allometry for body size in male-biased SSD species, whereas the alternative hypotheses were not supported by our data. These results highlight the importance of distinguishing male- and female-biased species as different evolutionary pressures and constraints may be at the basis of evolution of SSD in these groups.

I norovirus (NoV) sono piccoli virus a RNA monocatenario appartenenti alla famiglia Caliciviridae. Sulla base dell’analisi di sequenza del gene ORF2 codificante per la proteina capsidica VP1, i NoV sono attualmente classificati in sei genogruppi (G), con GI, GII e GIV responsabili di gastroenterite nell’uomo. Calicivirus enterici morfologicamente simili a NoV umani sono stati identificati per la prima volta in vitelli diarroici nel Regno Unito nel 1978 e in Germania nel 1980. Il sequenziamento nucleotidico dell’intero genoma ha permesso di classificare i NoV bovini (BoNoV) all’interno del genogruppo III in due genotipi, GIII.1 (prototipo Bo/Jena/80/DE) e GIII.2 (prototipo Bo/Newbury/76/UK). I BoNoV hanno una diffusione mondiale con una maggiore prevalenza di virus GIII.2-like. Tuttavia, studi recenti basati sull’analisi nucleotidica a livello della giunzione fra la polimerasi (RdRp) ed il capside, hanno dimostrato la circolazione di ceppi ricombinanti. Nel presente lavoro vengono riportati i risultati di un’indagine per la ricerca e tipizzazione di BoNoV condotta su quattro allevamenti bovini ubicati nelle province di Teramo e Pescara. A tal fine, 104 tamponi rettali collezionati da vitelli asintomatici sono stati sottoposti a nested RT-PCR impiegando due set di primer specifici per BoNoV in grado di amplificare un frammento di 326 bp della RdRp. L’RNA di BoNoV è stato identificato nel 10,5% (11/104) degli animali testati. L'analisi di sequenza ha evidenziato per nove sequenze un’elevata identità nucleotidica (nt) (88-96%) con i ceppi GIII.2-like, mentre per due è stata rilevata la maggiore identità (87-90% nt) con i BoNoV GIII.1-like. Per sette ceppi è stata ottenuta anche una sequenza di circa 750 bp che includeva oltre che la regione parziale della RdRp, la regione 5’ capsidica. Sulla base dell’analisi molecolare, cinque ceppi sono risultati strettamente correlati con BoNoV GIII.2-like, mentre solo uno dei due ceppi con polimerasi GIII.1-like, ha mostrato la maggiore identità nucleotidica nei confronti di BoNoV appartenenti al genotipo 1. Il ceppo 80/TE/IT che possedeva una polimerasi GIII.1-like, a livello capsidico ha mostrato la più alta identità con ceppi GIII.2-like, suggerendo un fenomeno di ricombinazione a livello della giunzione ORF1/ORF2.

I norovirus (NoV) sono piccoli virus (38-40 nm) a RNA monocatenario sprovvisti di envelope appartenenti alla famiglia Caliciviridae. I NoV attualmente vengono riconosciuti come una delle più importanti cause di gastroenterite acute di origine non batterica nell'uomo coinvolgendo tutte le classi di età e soprattutto contesti comunitari. I meccanismi molecolari che influenzano l'evoluzione dei NoV sono l'accumulo di mutazioni puntiformi e la ricombinazione. L’obiettivo sarà quello di dimostrare che la ricombinazione è un evento che può essere influenzabile dall’impiego di diversi parametri di coinfezione/superinfezione. In letteratura, gli studi sugli eventi ricombinanti che caratterizzano i NoV umani risultano piuttosto limitati a causa dell'assenza di un substrato cellulare che ne permetta la replicazione in vitro. Nel presente lavoro è stato sviluppato un modello sperimentale basato sull’impiego dell’unico NoV, il norovirus murino (MNV), in grado di replicare su substrato cellulare. A tal fine monostrati di cellule RAW264.7 sono stati coinfettati e superinfettati con due ceppi di MNV (CW1 e WU20) utilizzando diversi indici di molteplicità (MOI) e differenti tempi di infezione. I surnatanti sono stati collezionati a 24 e 48 ore post-infezione e quindi sottoposti a metodo delle placche. All’interno della popolazione virale risultante da tale coinfezione/superinfezione, 36 cloni per ciascuna condizione sono stati selezionati e purificati dalle placche e, successivamente, utilizzati per infettare nuovi monostrati cellulari di RAW264.7. Il monitoraggio degli eventi ricombinanti è stato eseguito mediante PCR e Real-Time PCR dopo estrazione dell'RNA virale e retrotrascrizione, impiegando due set di primer in grado di amplificare le regioni site all’estremità iniziale di ORF1 e all’estremità terminale di ORF3. I risultati che permetteranno di quantificare la distribuzione dei ceppi presenti nel surnatante della superinfezione, sono ancora in corso di analisi. [less ▲]
