Rostos na Street Art
Creators: name: Matos, Joana Gaudêncio
Publisher: name: Medi@ções
Year: 2014

description: O presente artigo, estruturado em torno de duas intervenções dos artistas portugueses Alexandre Farto e Sérgio Odeith, procurará analisar algumas das questões centrais do campo da street art. As intervenções aqui analisadas têm como finali-dades estabelecer uma proximidade e uma relação com a comunidade local, homenagear uma pessoa e estimular o debate em torno da street art. A utilização de técnicas e ferramentas de trabalho distintas, durante o processo artístico e criativo dos artistas, faz com que se insiram em diferentes esferas do universo da street art, embora tenham características e objetivos comuns. Uma das características comuns diz respeito à relação das intervenções com o retrato, género pre-sente nos murais dos artistas que têm como ponto de partida, a captura de uma fotografia tirada a um indivíduo de uma determinada comunidade. A fotografia aparece nestas práticas como uma ferramenta que auxilia os artistas a produzi-rem nos seus trabalhos novos enquadramentos e novas perspectivas.

A autoridade partilhada na Escola Pública Democrática
Creators: name: Silva, Cristina Gomes
Publisher: name: Medi@ções
Year: 2014

description: A discussão sobre a escola pública na atual sociedade democrática inscreve-se em várias frentes e os discursos que vão sendo produzidos descrevem-na mais facilmente pelo que não é, comparada com a escola do passado, do que pelo que é, registando-se alguma dificuldade na atualização do seu perfil de acordo com as novas exigências a que tem sido submetida. Um dos pontos de discussão tem a ver com a suposta perda de autoridade dos professores que surge associada à desvalorização da instituição escolar nas sociedades atuais. Tradicionalmente associada a ideologias de direita e a sociedades fechadas e/ou pouco democráticas, o conceito tem tido uma difícil atualização. Aquilo que aqui propomos é relançar a discussão e equacionar a autoridade numa associação feliz entre exercício da cidadania em contexto democrático, autonomia dos agen-tes sociais em sede escolar, articulação solidária entre o conceito de autoridade e o de autoria e autoridade partilhada e responsável.

description: The coupled nonlinear volatility and option pricing model presented recently by Ivancevic is investigated, which generates a leverage effect, i.e., stock volatility is (negatively) correlated to stock returns, and can be regarded as a coupled nonlinear wave alternative of the Black-Scholes option pricing model. In this short report, we analytically propose the two-component financial rogue waves of the coupled nonlinear volatility and option pricing model without an embedded w-learning. Moreover, we exhibit their dynamical behaviors for chosen different parameters. The two-component financial rogue wave solutions may be used to describe the possible physical mechanisms for the rogue wave phenomena and to further excite the possibility of relative researches and potential applications of rogue waves in the financial markets and other related fields.

description: Rationale & Objective: Lower rates of hypertension awareness, treatment, and control have been observed in Hispanics/Latinos compared with non-Hispanic whites. These factors have not been studied in Hispanics/Latinos with chronic kidney disease (CKD). We sought to describe the prevalence, awareness, treatment, and control of hypertension in Hispanic/Latino adults with CKD. Study Design: Cross-sectional cohort. Setting & Participants: US.Hispanics/Latinos aged 18 to 74 years enrolled in the Hispanic Community Health Study/Study of Latinos (HCHS/SOL) with CKD. Comparisons were made with the National Health and Nutrition Examination Survey (NHANES) 2007 to 2010. Exposure: CKD was defined as estimated glomerular filtration rate < 60 mL/min/1.73 m2 or urinry albumin-creatinine ratio ≥ 30 mg/g creatinine. Outcomes: Hypertension was defined as systolic blood pressure (BP) ≥ 140 or diastolic BP ≥ 90 mm Hg or use of antihypertensives. For hypertension control, 2 thresholds were examined: <140/90 and <130/80 mm Hg. Results: The prevalence of hypertension was 51.5%; among those with hypertension, hypertension awareness and treatment were present in 78.1% and 70.4%, respectively. A low prevalence of BP control was observed (32.6% with BP < 140/90 mm Hg; 17.9% with BP < 130/80 mm Hg). Health insurance coverage was associated with higher odds of BP < 140/90 mm Hg (OR, 1.98; 95% CI, 1.15-3.43). Compared with non-Hispanic whites with CKD in NHANES, HCHS/SOL participants with CKD had a lower prevalence of hypertension but a lower rate of BP control (32.6% vs 48.6% for BP < 140/90 mm Hg). Limitations: Use of a single measurement of creatinine, cystatin C, and urinary albumin excretion to define CKD. Single-visit measurement of BP. Conclusions: Hispanics/Latinos with CKD residing in the United States have very low rates of BP control. The association of health insurance coverage with hypertension control suggests that improved access to health care may improve outcomes for this growing population.
Inducing Barbero-Immirzi Connections along SU(2)-reductions of Bundles on Spacetime

description: We shall present here a general apt technique to induce connections along bundle reductions which is different from the standard restriction. This clarifies and generalizes the standard procedure to define Barbero-Immirzi (BI) connection, though on spacetime. The standard spacial BI connection used in LQG is then obtained by its spacetime version by standard restriction. The general prescription to define such a reduced connection is interesting from a mathematical viewpoint and it allows a general and direct control on transformation laws of the induced object. Moreover, unlike what happens by using standard restriction, we shall show that once a bundle reduction is given, then any connection induces a reduced connection with no constraint on the original holonomy as it happens when connections are simply restricted.

description: Within the Bose-Hubbard model, we theoretically determine the stationary states of two distinguishable atoms in a one-dimensional optical lattice and compare with the case of two identical bosons. A heterodimer has odd-parity dissociated states that do not depend on the interactions with the atoms, and the lattice momenta of the two atomic species may have different averages even for a bound state of the dimer. We discuss two possible methods of detecting the dimer. First, the different distributions of the quasimomenta of the two species may be observed in suitable time-of-flight experiments. Also, an asymmetry in the line shape as a function of the modulation frequency may reveal the presence of the odd-parity dissociated states when a heterodimer is dissociated by modulating the depth of the optical lattice.

description: Este artigo explora a dimensão política e estratégica que a língua portuguesa tem nos programas portugueses de cooperação para o desenvolvimento. Para melhor compreender a política linguística portuguesa através da cooperação, num pri-meiro momento, é apresentado o quadro teórico que tem sido internacionalmente desenvolvido pelos estudos em política linguística e é feita uma brevíssima carac-terização sociolinguística dos seis países que beneficiam da ajuda pública portu-guesa: Angola, Cabo Verde, Guiné-Bissau, Moçambique, São Tomé e Príncipe e Timor-Leste. Num segundo momento, são apresentados e analisados os docu-mentos nacionais e da Comunidade de Países de Língua Portuguesa que atual e oficialmente orientam a cooperação pública portuguesa: Estratégia de Promoção da Língua Portuguesa (2008), Conceito Estratégico da Cooperação Portuguesa (2014), Plano de Ação de Brasília (2010) e Plano de Ação de Lisboa (2013). Por fim, apresentam-se perspetivas de desenvolvimento da política de difusão do português que, no enquadramento atual, poderão potenciar a aprendizagem da língua nos países beneficiários da ajuda pública portuguesa. Considerando a tendência para a adoção da educação bilingue no início de escolaridade, aliada ao facto de este nível apenas abranger a população infantil, a reflexão proposta privilegiará, sempre que possível, a formação profissional de jovens e adultos, ao longo da vida, em português.

description: In questa ricerca ci si occupa del disegno figurativo improntato al realismo attraverso un percorso didattico volto alla rappresentazione dell’autoritratto. L’obiettivo del mio Lavoro di Diploma è di capire se sia possibile migliorare le competenze in termini di rappresentazione verosimile grazie a degli esercizi mirati ed un corretto accompagnamento della docente coinvolta nella ricerca-azione. Inoltre, ci si chiede se tale intervento possa portare gli allievi ad incrementare la loro soddisfazione e il senso di autoefficacia percepita nel disegno. Il campione di riferimento è la 4A dell’opzione di approfondimento specifico (ODAS), composta da 12 allievi. I dati sono raccolti attraverso l’osservazione in classe, l’analisi degli elaborati e dei tre questionari proposti ai ragazzi in fasi precise dell’itinerario. I dati emersi hanno permesso in primo luogo di comprendere che il desiderio da parte degli allievi adolescenti di rendere i propri disegni più realistici è palesemente presente. Secondariamente si è rilevato che con il supporto della docente e una co-costruzione del ragionamento nelle diverse fasi di realizzazione, la maggioranza ha applicato con maggior sicurezza e padronanza le nuove tecniche apprese, manifestando soddisfazione per i risultati ottenuti. Tale intervento ha quindi rappresentato un’occasione significativa e profondamente educativa, coinvolgendo delle importanti dimensioni extra-disciplinari fondamentali per lo sviluppo globale dell’allievo.

Star Formation on Galactic Scales: Empirical Laws

Publisher: name: arXiv
Year: 2011
Subjects: subject: Astrophysics of Galaxies (astro-ph.GA)
subject: FOS: Physical sciences

description: Empirical star formation laws from the last 20 years are reviewed with a comparison to simulations. The current form in main galaxy disks has a linear relationship between the star formation rate per unit area and the molecular cloud mass per unit area with a timescale for molecular gas conversion of about 2 Gyr. The local ratio of molecular mass to atomic mass scales nearly linearly with pressure, as determined from the weight of the gas layer in the galaxy. In the outer parts of galaxies and in dwarf irregular galaxies, the disk can be dominated by atomic hydrogen and the star formation rate per unit area becomes directly proportional to the total gas mass per unit area, with a consumption time of about 100 Gyr. The importance of a threshold for gravitational instabilities is not clear. Observations suggest such a threshold is not always important, while simulations generally show that it is. The threshold is difficult to evaluate because it is sensitive to magnetic and viscous forces, the presence of spiral waves and other local effects, and the equation of state.

description: Tendo como referência o Projeto Escola+, desenvolvido entre 2007 e 2012 em São Tomé e Príncipe, este artigo explora a dimensão política, estratégica e pedagógica que a língua portuguesa pode ter em projetos de cooperação. Considerando que, por ser língua oficial, é nesta língua que o ato educativo tem lugar e todo o sistema educativo se sustenta, o referido projeto fez emergir questões que estimularam o desenvolvimento de competências linguísticas dos seus intervenientes. Neste âmbito e não ignorando as Recomendações do Comité de Ajuda ao Desenvolvimento CAD, a Portugal, (OECD, 2010), é legítimo que se pergunte: deve a cooperação portuguesa focar-se apenas na promoção da língua portuguesa, ou adotar uma abordagem mais abrangente, perseguindo os objetivos que promovam o desenvolvimento desses países? Conciliando as duas posições e visando o futuro, defendemos que os projetos de cooperação em educação incluam objetivos que permitam aos seus destinatários, se assim o desejarem, o desenvolvimento e a consolidação de competências em língua portuguesa, enquanto capacidade endógena, no sentido em que, no mundo global, a língua portuguesa apresenta, hoje, uma vitalidade e uma dinâmica ? na literatura, na arte, na ciência ? valores intrínsecos que lhe permitem ombrear com outras línguas na comunicação internacional. Esta dimensão da língua pertence a todos que falam português.

"To retrieve what was left" : archival impulses in Caribbean diasporic fiction
Creators: name: Gantz, Lauren Jean
Publisher: name: The University of Texas at Austin
Year: 2014
Subjects: Caribbean
Trauma
Archive
Literature
Diaspora

description: This dissertation analyzes a recurring phenomenon in late-twentieth and early twenty-first century diasporic Caribbean novels that I label the “archival impulse”—by which I mean depictions of artifacts, documents, collection, and curatorship. Archives have a particularly pernicious history in the Caribbean, where they have been deployed by colonial and totalitarian regimes alike to dictate who is considered human, to silence sub-altern voices, and to legitimize state violence. “To retrieve what was left” thus conceives of the archive itself as a source of trauma for Caribbean subjects, and the archival impulse as authors’ efforts to confront that trauma. This impulse marks an important shift in how and why Caribbean literatures reconstruct the past. While previous generations of Caribbean writers imagined corrective histories to enact political resistance, the texts I examine are also deeply interested in the psychological effects of encountering history. Archival materials, as physical remnants of the past, are ideal points of focus for dramatizing such encounters. I identify two iterations of the archival impulse in diasporic literature from the Anglophone and Spanish-speaking Caribbeans. The first, which I examine in Michelle Cliff’s Abeng (1985) and No Telephone to Heaven (1987), as well as Julia Alvarez’s In the Name of Salomé (2000), portrays archives and curatorial practices in order to acknowledge the fragmented, indeterminate, and often, painful nature of the Caribbean past. These works attempt to heal that past by generating counterarchives and provisional histories. In contrast, the second iteration, which I theorize using Dionne Brand’s At the Full and Change of the Moon (1999) and Junot Díaz’s The Brief Wondrous Life of Oscar Wao (2007), is circumspect about redemptive histories. These texts depict archives and curatorship to emphasize the irreparable aspects of Caribbean history. Dwelling on the psychic pain inflicted by encounters with the past, these works suggest that even tentative narratives of healing are forced—and perhaps damaging to Caribbean subjects. Ultimately, this dissertation asks what obligation Caribbean literature has to the region’s history: whether to work through history for purposes of recuperation, or to demand a reckoning with history as an unhealed and un-healable trauma?
Effects of training with and without cultural adaptations to Latino caregivers of children with autism

description: For families of children with autism spectrum disorder (ASD), caregiver training has the power to positively impact the child’s development and the family’s quality of life. With training, caregivers can learn how to implement strategies to successfully reduce challenging behavior and increase adaptive skills in their child with ASD. Nevertheless, culturally and linguistically diverse (CLD) families face unique challenges to access services that match their culture and language. Furthermore, the scarcity of appropriate practices when serving CLD families and the shortage of bilingual therapists add to the limitations of providing culturally adapted services for these families. To reduce this disparity for CLD families, it is essential to better understand the impact of current practices, when there is a mismatch between the family and training language, and when training has been culturally adapted. Therefore, the purpose of this study was to evaluate the effects of implementing caregiver training with and without cultural and linguistic adaptations on four Latino caregivers of children with ASD. A delayed multiple baseline design across caregiver-child dyads with an embedded alternating treatment design was conducted to investigate the relative effects of language on instruction, using English versus Spanish languages and teaching caregivers, via Telehealth, two different skills: (a) matching to sample and (b) motor imitation during play. Caregiver social validity, the child’s skill acquisition, and the training efficiency were also assessed. Results indicated that CLD families can benefit from training regardless of the language mismatch and that, with training, caregivers can positively impact their child’s performance. However, training that has been culturally adapted to match the family language has proven to be more efficient. In these circumstances, caregivers acquired the skill in fewer sessions, and their learning process was more stable. Caregivers indicated that the training in their native language was easier and more comfortable. Also, caregivers were more involved during training sessions that were culturally adapted. For instance, caregivers shared more personal information — “personalismo”—asked more questions, and showed more indices of happiness (e.g., laughing). Treatment gains were maintained during two-week and one-month follow-ups. Potential implications for policy and practice and recommendations for practitioners working with CLD families of children with ASD are provided, in addition to possible areas of future research.

description: Saper argomentare le proprie opinioni è complesso. Ciononostante, ogni individuo, nel corso della propria vita ne è confrontato. Questo lavoro considera anche un altro elemento: il museo, il quale è un luogo di apprendimento che offre molti stimoli. La domanda alla quale si vuole rispondere in questo studio è: “In che misura le visite al museo e relative mediazioni incrementano le capacità argomentative del bambino?”. Al fine di rispondere a tale interrogativo è stato progettato un itinerario pedagogico-didattico che verrà valutato sia a livello quantitativo (in tal caso saranno considerati i risultati di ogni allievo) che a livello qualitativo (per quest’ultimo saranno esaminati sei di loro). Questo percorso sarà sottoposto ad una classe di seconda elementare composta da 21 alunni. I risultati evidenziano un incremento sia a livello qualitativo che quantitativo delle argomentazioni dei bambini. Tale lavoro di ricerca potrebbe quindi essere un punto di partenza per ulteriori studi in seno a attività incentrate sul testo argomentativo al museo in classi di primo ciclo.

Musica: un mondo di emozioni? Educazione socio-emotiva nell'ambito della musica

description: Il mio progetto presenta come tema focale l’educazione musicale in rapporto all’educazione emotiva. Tratta le rappresentazioni che docenti e bambini negli ordini di scuola SI e SE hanno per rapporto alla musica legata alle emozioni molto spesso unicamente somministrata attraverso ascolti di brani musicali. Non esistono invece molte canzoni che trattano anche nel testo degli aspetti emozionali. Ho quindi deciso di creare del materiale che permettesse di analizzare in modo esplicito l’argomento “emozioni”. In primo luogo ho quindi creato delle canzoni (“Emozioni” e “Lo specchio delle emozioni”). La ricerca è basata su un confronto di opinioni ed è pertanto di ordine qualitativo. Nella metodologia, attraverso la forma dell’indagine, ho intervistato i b.ni di 2 classi di seconda, 2 di terza e 2 di quinta SE e 2 sezioni SI. Inoltre ho inviato un questionario ai docenti delle classi assegnatemi e a una trentina di docenti di educazione musicale. I risultati ottenuti hanno dettato il seguente quadro: i materiali ideati sono stati un ottimo strumento per entrare in relazione con i b.ni. Tutti i docenti interpellati riconoscono l’importanza della musica nello sviluppo emotivo degli alunni. Pochi però sono stati in grado di sostanziare con esempi pratici le loro dichiarazioni. Quindi il dubbio resta: questa importanza dichiarata viene anche vissuta? Relatore: Giovanni Galfetti

description: This document presents a new method and tool for controlling the thicknesses and quality of exfoliated monocrystalline silicon thin-films. The method described here is compatible with traditional wafer-based, metal-oxide-semiconductor (CMOS) fabrication techniques. It enables high-performance devices fabricated using CMOS processes to be easily integrated into flexible electronic products such as wearable or Internet of Things (IoT) devices. A finite-element linear-elastic fracture mechanics study was performed to understand the parameters that control the exfoliation process. A metamodel was created from the simulation results to inform the design and operation of a new exfoliation tool. This new exfoliation tool improves on previous iterations by creating a controlled peeling force that propagates the crack in a precise manner while utilizing the metamodel to produce higher quality films and actively compensate for errors in the tensile layer. Inline metrology was added to the tool to enable the error compensation. A careful precision design of the tool stage stage was performed to ensure the accuracy of the inline metrology. The results confirm the new tool's ability to correct the crack trajectory and show improvement in the uniformity and quality of the exfoliation compared to previous methods.

Como se constatará ao longo do artigo, o projeto de formação em análise questiona os limites da educação e da aprendizagem formal e informal, por via da disrupção proporcionada pelo uso de linguagens não académicas e de contextos não-escolares na construção, experimentação e apresentação de novos gestos pedagógicos. Enquadramos o nosso estudo na análise de concepções de DPC, de sistematizações de objectivos e modalidades da oferta de programas de DPC e em discussões recentes sobre a profissionalidade docente, no sentido de questionar os entendimentos tradicionais do DPC e transgredir os limites entre formal e informal na análise de estratégias de DPC, pluralizando o conceito.

The opposition and tilt effects of Saturn's rings from HST observations

description: The two major factors contributing to the opposition brightening of Saturn's rings are i) the intrinsic brightening of particles due to coherent backscattering and/or shadow-hiding on their surfaces, and ii) the reduced interparticle shadowing. We utilize the Hubble Space Telescope observations for different elevation angles B to disentangle these contributions. We assume that the intrinsic contribution is independent of B, so that any B dependence of the phase curves is due to interparticle shadowing, which must also act similarly for all colors. We construct a grid of dynamical/photometric simulation models to fit the elevation-dependent part of opposition brightening. Eliminating the modeled interparticle component yields the intrinsic contribution to the opposition effect: for the B and A rings it is almost entirely due to coherent backscattering; for the C ring, an intraparticle shadow hiding contribution may also be present. Based on our simulations, the width of the interparticle shadowing effect is roughly proportional to B. This follows from the observation that as B decreases, the scattering is primarily from the rarefied low filling factor upper ring layers, whereas at larger $B$'s the dense inner parts are visible. The elevation angle dependence of interparticle shadowing also explains most of the B ring tilt effect (the increase of brightness with elevation). From comparison of the magnitude of the tilt effect at different filters, we show that multiple scattering can account for at most a 10% brightness increase as B -> 26^o, whereas the remaining 20% brightening is due to a variable degree of interparticle shadowing. The negative tilt effect of the middle A ring is well explained by the the same self-gravity wake models that account for the observed A ring azimuthal brightness asymmetry.

Efficacy of endoscopic third ventriculostomy to treat cognitive symptoms in adults with chronic obstructive hydrocephalus
Creators: name: Salterio, Nicholas
Publisher: name: University of British Columbia

description: Hydrocephalus is a neurological disease caused by an overaccumulation of cerebrospinal fluid (CSF) within the ventricles of the brain. This produces expansion of the ventricles (ventriculomegaly) and compression of the surrounding brain tissue. Obstructive hydrocephalus is the result of a macroscopic blockage within the ventricular system distal to the arachnoid villi and can produce cognitive decline. Endoscopic third ventriculostomy (ETV) has been shown to be a safe surgical treatment in obstructive hydrocephalus, however the efficacy of ETV to improve cognition has limited evidence. In order to determine how ETV affects cognition in adults who have chronic obstructive hydrocephalus, this thesis had the following objectives: 1) to determine the sufficiency of primary ETV to safely improve global cognition in adults with chronic obstructive hydrocephalus, and 2) to determine which cognitive domains ETV produces clinically meaningful changes in adults with chronic obstructive hydrocephalus. To complete the first objective, we conducted a multicenter study using the Montreal Cognitive Assessment (MoCA) and Symbol Digit Modality Test (SDMT), measures of global cognition and processing speed, before and twice after ETV at 5-months and 14-months follow-up. We found that global cognition was only clinically improved at 14-months follow-up and processing speed was unaffected. Global cognitive worsening was rare at both follow-up assessments. To complete the second objective, we conducted a single-center study using the RBANS to measure global cognition in better detail and five cognitive domains before and after ETV. We found patients with chronic obstructive hydrocephalus treated with ETV have a clinically and statistically significant improvement in global cognition, attention, and delayed memory domains at 4-months follow-up. Clinical worsening was rare in all domains except visuospatial/constructional, where although there was no statistical difference, 50% of patients had a clinical worsening post-ETV. Lastly, a potential predictor of post-ETV global cognitive improvement was discovered. The likelihood of global cognition improvement was 100% when the difference between immediate and delayed memory indexes were three points or less. Further validation of this predictor is required. Future studies should expand on the neurocognitive testing to include anatomical correlates to elucidate the mechanism of cognitive decline seen in chronic obstructive hydrocephalus.

description: We present a reflexive tactic for deciding the equational theory of Kleene algebras in the Coq proof assistant. This tactic relies on a careful implementation of efficient finite automata algorithms, so that it solves casual equations instantaneously and properly scales to larger expressions. The decision procedure is proved correct and complete: correctness is established w.r.t. any model by formalising Kozen's initiality theorem; a counter-example is returned when the given equation does not hold. The correctness proof is challenging: it involves both a precise analysis of the underlying automata algorithms and a lot of algebraic reasoning. In particular, we have to formalise the theory of matrices over a Kleene algebra. We build on the recent addition of firstorder typeclasses in Coq in order to work efficiently with the involved algebraic structures.
X-ray selected Infrared Excess AGN in the Chandra Deep Fields: a moderate fraction of Compton-thick sources

description: We examine the properties of the X-ray detected, Infrared Excess AGN or Dust Obscured Galaxies (DOGs) in the Chandra Deep Fields (CDF). We find 26 X-ray selected sources which obey the 24 micron to R-band flux ratio criterion f_24/f_R>1000. These are at a median redshift of 2.3 while their IR luminosities are above 10^12 solar. Their X-ray luminosities are all above a few times 10^42 erg s-1 in the 2-10 keV band unambiguously arguing that these host AGN. Nevertheless, their IR Spectral Energy Distributions are split between AGN (Mrk231) and star-forming templates (Arp220). Our primary goal is to examine their individual X-ray spectra in order to assess whether this X-ray detected DOG population contains heavily obscured or even Compton-thick sources. The X-ray spectroscopy reveals a mixed bag of objects. We find that four out of the 12 sources with adequate photon statistics and hence reliable X-ray spectra, show evidence for a hard X-ray spectral index (~1) or harder,consistent with a Compton-thick spectrum. In total 12 out of the 26 DOGs show evidence for flat spectral indices. However, owing to the limited photon statistics we cannot differentiate whether these are flat because they are reflection-dominated or because they show moderate amounts of absorption. Seven DOGs show relatively steep spectra (>1.4) indicative of small column densities. All the above suggest a fraction of Compton-thick sources that does not exceed 5%. The average X-ray spectrum of all 26 DOGs is hard (~1.1) or even harder (~0.6) when we exclude the brightest sources. These spectral indices are well in agreement with the stacked spectrum of X-ray undetected sources (~0.8 in the CDFN). This could suggest (but not necessarily prove) that X-ray undetected DOGs, in a similar fashion to the X-ray detected ones presented here, are hosting a moderate fraction of Compton-thick sources.

description: Minimal hepatic encephalopathy (MHE) is a common neuropsychiatric complication of liver cirrhosis. Both EncephalApp Stroop test (EncephalApp) and electronic number connection test-A (eNCT-A) are novel computerised psychometric tests for MHE screening. We aimed to compare the efficiency, convenience, accessibility, and acceptability of EncephalApp with that of eNCT-A for MHE screening in cirrhotic patients. Ninety-five patients with hepatitis B-induced liver cirrhosis were included and respectively tested by the psychometric hepatic encephalopathy score (PHES), EncephalApp, and eNCT-A. Using PHES as the gold standard for MHE diagnosis, the efficiency of EncephalApp and eNCT-A for MHE screening were respectively analysed by the receiver operating characteristic (ROC) curve, and the areas under the ROC curve (AUROC) were compared. The convenience, accessibility, and acceptability of PHES, EncephalApp and eNCT-A were respectively evaluated by the 5-point Likert scale. Fifty-two (55%) of included cirrhotic patients were diagnosed with MHE. The EncephalApp had a sensitivity of 84.6%, a specificity of 74.4%, and an AUROC of 0.836. Meanwhile, the eNCT-A had a sensitivity of 78.8%, a specificity of 83.7%, and an AUROC of 0.845. No significant difference in AUROC was detected between the EncephalApp and eNCT-A (p = .453). Compared with the EncephalApp, the eNCT-A presented better convenience and higher acceptability in cirrhotic patients undergoing MHE screening (p = .019 and p < .001, respectively). As with the EncephalApp, the eNCT-A will be a potential home monitoring and point-of-care tool for cirrhotic patients at high risk of MHE.
Star Formation in Spiral Arms

description: The origin and types of spiral arms are reviewed with an emphasis on the connections between these arms and star formation. Flocculent spiral arms are most likely the result of transient instabilities in the gas that promote dense cloud formation, star formation, and generate turbulence. Long irregular spiral arms are usually initiated by gravitational instabilities in the stars, with the gas contributing to and following these instabilities, and star formation in the gas. Global spiral arms triggered by global perturbations, such as a galaxy interaction, can be wavemodes with wave reflection in the inner regions. They might grow and dominate the disk for several rotations before degenerating into higher-order modes by non-linear effects. Interstellar gas flows through these global arms, and through the more transient stellar spiral arms as well, where it can reach a high density and low shear, thereby promoting self-gravitational instabilities. The result is the formation of giant spiral arm cloud complexes, in which dense molecular clouds form and turn into stars. The molecular envelops and debris from these clouds appear to survive and drift through the interarm regions for a long time, possibly 100 Myr or more, with lingering spontaneous star formation and triggered star formation in the pieces that are still at high-pressure edges near older HII regions.
