description: Abstract: This paper investigates the impact of thermal treatment on the pressure drop of particulate filters containing ash deposits. A one-dimensional model has been developed and applied to describe the deposition of soot and ash particles, and estimate the spatial distribution of the deposits in such filters. Phenomenological models have been developed to describe the potential sintering and cracking of the ash deposits caused by thermal treatment of the filter. The model results are in good agreement with experimental measurements of the reduction in the pressure drop in thermally treated filters. It was found that crack formation in the ash layer can lead to significant reduction of the pressure drop at relatively low temperatures. Sintering of ash deposits in the wall and the ash plug also contributes towards a decrease in filter pressure drop at higher temperatures. This work is the first attempt to model the impact of the thermal treatment of ash in particulate filters in order to support the development of future ash management strategies. The cracking of the ash layer during the thermal treatment has been identified to be the most critical effect for pressure drop reduction.

description: Η παρούσα διπλωματική εργασία προσδιορίζει την διαθεσιμότητα του mentoring και την επίδραση αυτού στην ικανοποίηση από την καριέρα και την επαγγελματική ανέλιξη των ειδικευόμενων ιατρών στα ελληνικά νοσοκομεία. Το ερωτηματολόγιο της ερευνητικής αυτής εργασίας διαμοιράστηκε σε ειδικευόμενους ιατρούς αξιοποιώντας τα μέσα κοινωνικής δικτύωσης. Τα αποτελέσματα αναδεικνύουν την σημασία του/της μέντορα ως «δίκτυο υποστήριξης» στα χρόνια της ειδικότητας, και την σημαντική συνεισφορά του mentoring στην ικανοποίηση από την καριέρα, την ποιότητα ζωής, και την εργασιακή ευημερία των ειδικευόμενων ιατρών. Οι διαφορές στην επαγγελματική ανέλιξη, τις τάσεις απέναντι στην έρευνα, τις σπουδές σε μεταπτυχιακό και διδακτορικό επίπεδο, και την εξειδίκευση εντός της ειδικότητας των δύο ομάδων (με και χωρίς υποστήριξη mentoring) δεν βρέθηκαν στατιστικά σημαντικές. Οι δημογραφικοί παράγοντες (φύλο, ειδικότητα) δεν βρέθηκαν να επηρεάζουν την διαθεσιμότητα του mentoring. Τα αποτελέσματα αυτά επιβεβαιώνουν την ωφέλιμη επίδραση του mentoring στα χρόνια της ειδικότητας, και τονίζουν την ανάγκη ενίσχυσης αυτού (μέσω π.χ. καθιέρωσης επίσημων προγραμμάτων mentoring) για την υποστήριξη των ειδικευόμενων ιατρών, την μεταλαμπάδευση γνώσεων, και την πρόοδο της ιατρικής επιστήμης συνολικά.
description: This master’s thesis measures the availability of mentoring and its impact on career satisfaction and professional advancement of resident doctors in Greek hospitals. The questionnaire of this study was distributed to resident doctors using social media platforms. The results highlight the importance of the mentor as a "support network" during the residency years, as well as the significant contribution of mentoring to career satisfaction, quality of life, and work well-being for resident doctors. Differences in professional advancement, attitudes towards research, postgraduate and doctoral studies, and specialization within the field between the two groups (mentored and non-mentored) were not found to be statistically significant. Demographic factors (gender, specialty) were not found to influence the availability of mentoring. These results confirm the beneficial impact of mentoring during the residency years and emphasize the need to strengthen it (e.g., through the establishment of formal mentoring programs) to support resident doctors, facilitate knowledge transfer, and advance Medicine as a whole.

description: A new unified video analytics framework (ER3) is proposed for complex event retrieval, recognition and recounting, based on the proposed video imprint representation, which exploits temporal correlations among image features across video frames. With the video imprint representation, it is convenient to reverse map back to both temporal and spatial locations in video frames, allowing for both key frame identification and key areas localization within each frame. In the proposed framework, a dedicated feature alignment module is incorporated for redundancy removal across frames to produce the tensor representation, i.e., the video imprint. Subsequently, the video imprint is individually fed into both a reasoning network and a feature aggregation module, for event recognition/recounting and event retrieval tasks, respectively. Thanks to its attention mechanism inspired by the memory networks used in language modeling, the proposed reasoning network is capable of simultaneous event category recognition and localization of the key pieces of evidence for event recounting. In addition, the latent structure in our reasoning network highlights the areas of the video imprint, which can be directly used for event recounting. With the event retrieval task, the compact video representation aggregated from the video imprint contributes to better retrieval results than existing state-of-the-art methods.

description: SIMP is a proper motion (PM) survey made with the Observatoire du Mont Megantic (OMM) wide-field near-infrared camera CPAPIR at the CTIO 1.5 m and OMM 1.6 m telescopes. The SIMP observations were initiated in early 2005, are still ongoing and, to date, have covered 28% of the sky at high galactic latitudes. The PMs of the sources detected are determined by comparing their measured positions with those listed in the 2MASS point source catalog, giving a time baseline of 4 to 10 years. The 5 sigma uncertainty on the relative SIMP and 2MASS astrometry is 1", equivalent to a PM lower limit of 0.125-0.250"/yr, or a tangential velocity limit of 15-30 km/s at 25 pc. Up to the 2MASS magnitude limit (J~16.5), T dwarfs are found out to ~25 pc, while L dwarfs may be found as far as 100 pc away.

description: Abstract: We study the structure of the Liouville quantum gravity (LQG) surfaces that are cut out as one explores a conformal loop-ensemble CLEκ′ for κ′ in (4, 8) that is drawn on an independent γ-LQG surface for γ2=16/κ′. The results are similar in flavor to the ones from our companion paper dealing with CLEκ for κ in (8/3, 4), where the loops of the CLE are disjoint and simple. In particular, we encode the combined structure of the LQG surface and the CLEκ′ in terms of stable growth-fragmentation trees or their variants, which also appear in the asymptotic study of peeling processes on decorated planar maps. This has consequences for questions that do a priori not involve LQG surfaces: In our paper entitled “CLE Percolations” described the law of interfaces obtained when coloring the loops of a CLEκ′ independently into two colors with respective probabilities p and 1-p. This description was complete up to one missing parameter ρ. The results of the present paper about CLE on LQG allow us to determine its value in terms of p and κ′. It shows in particular that CLEκ′ and CLE16/κ′ are related via a continuum analog of the Edwards-Sokal coupling between FKq percolation and the q-state Potts model (which makes sense even for non-integer q between 1 and 4) if and only if q=4cos2(4π/κ′). This provides further evidence for the long-standing belief that CLEκ′ and CLE16/κ′ represent the scaling limits of FKq percolation and the q-Potts model when q and κ′ are related in this way. Another consequence of the formula for ρ(p, κ′) is the value of half-plane arm exponents for such divide-and-color models (a.k.a. fuzzy Potts models) that turn out to take a somewhat different form than the usual critical exponents for two-dimensional models.

description: We present time-resolved V-photometry of the old nova RR Pic. Apart from the hump-like variability, the light curves show the strong flickering and random variation typical for RR Pic. We do not find any convincing evidence for the previously reported eclipse. The extrapolated eclipse phase coincides with a broad minimum, but comparing the overall shape of the light curve suggests that the eclipse should actually be located around phase 0.2. The orbital period which we derive from these data agrees well with the old one, any uncertainty is too small to account for the possible phase shift. Apart from the 3.48h period, which is usually interpreted as the orbital one, we find an additional period at P=3.78h, which we interpret as the superhump period of the system; the corresponding precession period at 1.79d is also present in the data. We also find indications for the presence of a 13min quasi-periodic oscillation.

description: Background: The quality of evidence about the effectiveness of non-pharmaceutical health interventions is often low, but little is known about the effects of communicating indications of evidence quality to the public. Methods: In two blinded, randomised, controlled, online experiments, US participants (total n = 2140) were shown one of several versions of an infographic illustrating the effectiveness of eye protection in reducing COVID-19 transmission. Their trust in the information, understanding, feelings of effectiveness of eye protection, and the likelihood of them adopting it were measured. Findings: Compared to those given no quality cues, participants who were told the quality of the evidence on eye protection was ‘low’, rated the evidence less trustworthy (p = .001, d = 0.25), and rated it as subjectively less effective (p = .018, d = 0.19). The same effects emerged compared to those who were told the quality of the evidence was ‘high’, and in one of the two studies, those shown ‘low’ quality of evidence said they were less likely to use eye protection (p = .005, d = 0.18). Participants who were told the quality of the evidence was ‘high’ showed no statistically significant differences on these measures compared to those given no information about evidence quality. Conclusions: Without quality of evidence cues, participants responded to the evidence about the public health intervention as if it was high quality and this affected their subjective perceptions of its efficacy and trust in the provided information. This raises the ethical dilemma of weighing the importance of transparently stating when the evidence base is actually low quality against evidence that providing such information can decrease trust, perception of intervention efficacy, and likelihood of adopting it.
A Possible Approach to Inclusion of Space and Time in Frame Fields of Quantum Representations of Real and Complex Numbers

description: This work is based on the field of reference frames based on quantum representations of real and complex numbers described in other work. Here frame domains are expanded to include space and time lattices. Strings of qukits are described as hybrid systems as they are both mathematical and physical systems. As mathematical systems they represent numbers. As physical systems in each frame the strings have a discrete Schrodinger dynamics on the lattices. The frame field has an iterative structure such that the contents of a stage j frame have images in a stage j-1 (parent) frame. A discussion of parent frame images includes the proposal that points of stage j frame lattices have images as hybrid systems in parent frames. The resulting association of energy with images of lattice point locations, as hybrid systems states, is discussed. Representations and images of other physical systems in the different frames are also described.

description: We present LMT/AzTEC 1.1mm observations of $\sim100$ luminous high-redshift dusty star-forming galaxy candidates from the $\sim600\,$sq.deg $Herschel$-ATLAS survey, selected on the basis of their SPIRE red far-infrared colours and with $S_{500μ\rm m}=35-80$ mJy. With an effective $θ_{\rm FWHM}\approx9.5\,$ arcsec angular resolution, our observations reveal that at least 9 per cent of the targets break into multiple systems with SNR $\geq 4$ members. The fraction of multiple systems increases to $\sim23\,$ per cent (or more) if some non-detected targets are considered multiples, as suggested by the data. Combining the new AzTEC and deblended $Herschel$ photometry we derive photometric redshifts, IR luminosities, and star formation rates. While the median redshifts of the multiple and single systems are similar $(z_{\rm med}\approx3.6)$, the redshift distribution of the latter is skewed towards higher redshifts. Of the AzTEC sources $\sim85\,$ per cent lie at $z_{\rm phot}>3$ while $\sim33\,$ per cent are at $z_{\rm phot}>4$. This corresponds to a lower limit on the space density of ultra-red sources at $44$ galaxies.

Non-thermal bremsstrahlung from supernova remnants and the effect of Coulomb losses
Creators: name: Vink, Jacco
Publisher: name: arXiv
Year: 2008
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: I investigate the shape of the electron cosmic ray spectrum in the range up to ~1000 keV, assuming that the acceleration process at the shock results in a power law in momentum, and that downstream of the shock the spectrum is affected by Coulomb interactions with background electrons only. In the non-relativistic regime one can analytically determine the energy of an electron starting with a certain energy, and use this result to produce an electron cosmic ray spectrum, modified by Coulomb losses. An analytic expression for the electron spectrum is obtained that depends on the parameter n_e t, which can be estimated from a similar parameter used to characterize the line spectra of supernova remnants. For the brightest supernova remnants n_e t > 1e11 cm^-3 s,and most of the electrons accelerated to < 100 keV have lost their energy. Because of its high radio flux, Cas A is the most likely candidate for non-thermal bremsstrahlung. Although it has n_e t ~ 2e11 cm^-3 s, one may expect to pick up non-thermal bremsstrahlung above 100 keV with current hard X-ray detectors.

description: After the first week of the Corona lockdown of the Austrian economy and society, the domestic Cultural and Creative Industry (CCI) is facing unprecedented challenges. In order to attempt to measure the consequences of these provisions, the European Creative Business Network has carried out a snapshot survey about the effects and affects of the fight against the spread of the new coronavirus on the Austrian cultural and creative industries. The self-assessment by the participants reflected in this study is alarming. The absolute majority of the participants of this snapshot survey expect sale losses. The figures, which refer to the overall economic figures for the Austrian creative industries, are also worrying. Based on this self-assessment, this means, in the long term, that the crisis could lead to a loss of EUR 3 billion in gross annual value added for CCIs in the Austrian market.

description: Recent experiments indicate that Na$_4$Ir$_3$O$_8$, a material in which s=1/2 iridium local moments form a three dimensional network of corner-sharing triangles, may have a quantum spin liquid ground state with gapless spin excitations. Using a combination of exact diagonalization, symmetry analysis of fermionic mean field ground states and Gutzwiller projected variational wavefunction studies, we propose a quantum spin liquid with spinon Fermi surfaces as a favorable candidate for the ground state of the Heisenberg model on the hyper-kagome lattice of Na$_4$Ir$_3$O$_8$. We present a renormalized mean field theory of the specific heat of this spin liquid and also discuss possible low temperature instabilities of the spinon Fermi surfaces.

description: Abstract: Episodic memory—memory for personally experienced past events—seems to afford a distinctive kind of cognitive contact with the past. This makes it natural to think that episodic memory is centrally involved in our understanding of what it is for something to be in the past, or to be located in time—that it is either necessary or sufficient for such understanding. If this were the case, it would suggest certain straightforward evidential connections between temporal cognition and episodic memory in nonhuman animals. In this paper, I argue that matters are more complicated than this. Episodic memory is memory for events and not for the times they occupy. As such, it is dissociable from temporal understanding. This is not to say that episodic memory and temporal cognition are unrelated, but that the relationship between them cannot be straightforwardly captured by claims about necessity and sufficiency. This should inform our theoretical predictions about the manifestations of episodic memory in nonhuman behaviour.

description: The aim of this paper is to explore ways in which small tourism-based enterprises can offer a crisis-resilient pathway to sustainable development. Based on a mixed-embeddedness framework, this paper explores the multiple strategies that small enterprises in the silver souvenir industry of Kotagede (Yogyakarta, Indonesia) applied to cope with hardship during the Indonesian decade of crisis (1996-2006). The data on which this paper builds stem from qualitative research conducted in Yogyakarta over a time span of 20 years. This paper makes two contributions to the current literature. The first contribution is to offer empirical, longitudinal, primary data on small-firm performances against the background of fluctuations in the tourism industry. The second contribution is conceptual, arguing that an embeddedness approach, sensitive to location-specific characteristics, promises a better understanding of small tourism enterprises as crisis-resilient development path- ways. In doing so, this paper also asserts that small businesses, due to their embeddedness in household economies and subcontracting arrangements that include rural labor, have the capacity to become agents of the United Nation’s Sustainable Development Goals.

description: Abstract: Our innate immune responses to viral RNA are vital defenses. Long cytosolic double-stranded RNA (dsRNA) is recognized by MDA5. The ATPase activity of MDA5 contributes to its dsRNA binding selectivity. Mutations that reduce RNA selectivity can cause autoinflammatory disease. Here, we show how the disease-associated MDA5 variant M854K perturbs MDA5-dsRNA recognition. M854K MDA5 constitutively activates interferon signaling in the absence of exogenous RNA. M854K MDA5 lacks ATPase activity and binds more stably to synthetic Alu:Alu dsRNA. CryoEM structures of MDA5-dsRNA filaments at different stages of ATP hydrolysis show that the K854 sidechain forms polar bonds that constrain the conformation of MDA5 subdomains, disrupting key steps in the ATPase cycle- RNA footprint expansion and helical twist modulation. The M854K mutation inhibits ATP-dependent RNA proofreading via an allosteric mechanism, allowing MDA5 to form signaling complexes on endogenous RNAs. This work provides insights on how MDA5 recognizes dsRNA in health and disease.

description: Volunteer tourism is an ever-growing phenomenon and a multi-million-pounds industry, particularly in developing countries. Despite the manifold criticism for its neo-colonial nature – self-centered volunteers who romanticize the Global South as ‘poor but happy’ and short-term projects that create dependency rather than local capacity – it can, at the same time, be seen as a key engine for socio-economic development. The privatization and neo-liberalization of development has led to governments and development agencies increasingly delegating responsibilities to the volunteer, who takes on the role of an agent of development – continuing in times of the SDGs-driven Agenda 2030. However, little research to date tries to understand volunteers’ perceived developmental impact to link it with the UN Sustainable Development Goals (SDGs) that characterize the current development agenda. This paper, therefore, offers one of the first attempts to bridge the gap between volunteers’ experiences, their felt impact, and the SDGs by drawing on ethno- graphic data gathered in a volunteer project teaching English in the North of Bali. Its aim is to start a discussion as to whether and under which conditions volunteer tourism can be a viable instrument in line with Agenda 2030. Findings identify a range of obstacles for volunteer tourism in the Balinese context to be in line with the SDGs. These include a lack of needed skills and feeling of uselessness on volunteers’ part, expectations that are set too high through marketing, a lack of coordination, and the fact that projects don’t focus on the marginalized. However, there are also indications that volunteer tourism holds strong potential to put the SDGs’ universality into practice, and hence dissolve some of the bina- ries between North and South, and rich and poor – thereby creating true reciprocal partnerships, rather than encounters that are characterized by neo-colonial Othering.

Floer Theory of Higher Rank Quiver 3-folds
Creators: name: Smith, Ivan

Subjects: Original Research

description: Abstract: We study threefolds Y fibred by Am-surfaces over a curve S of positive genus. An ideal triangulation of S defines, for each rank m, a quiver Q(Δm), hence a CY3-category C(W) for any potential W on Q(Δm). We show that for ω in an open subset of the Kähler cone, a subcategory of a sign-twisted Fukaya category of (Y, ω) is quasi-isomorphic to (C, W[ω]) for a certain generic potential W[ω]. This partially establishes a conjecture of Goncharov (in: Algebra, geometry, and physics in the 21st century, Birkhäuser/Springer, Cham, 2017) concerning ‘categorifications’ of cluster varieties of framed PGLm+1-local systems on S, and gives a symplectic geometric viewpoint on results of Gaiotto et al. (Ann Henri Poincaré 15(1):61–141, 2014) on ‘theories of class S’.
GA-NET: Global Attention Network for Point Cloud Semantic Segmentation

description: How to learn long-range dependencies from 3D point clouds is a challenging problem in 3D point cloud analysis. Addressing this problem, we propose a global attention network for point cloud semantic segmentation, named as GA-Net, consisting of a point-independent global attention module and a point-dependent global attention module for obtaining contextual information of 3D point clouds in this paper. The point-independent global attention module simply shares a global attention map for all 3D points. In the point-dependent global attention module, for each point, a novel random cross attention block using only two randomly sampled subsets is exploited to learn the contextual information of all the points. Additionally, we design a novel point-adaptive aggregation block to replace linear skip connection for aggregating more discriminate features. Extensive experimental results on three 3D public datasets demonstrate that our method outperforms state-of-the-art methods in most cases.

description: Sex work is part of Thailand’s tourism-based economic development model. The country’s global reputation as a ‘queer paradise’ is an important factor shaping Thailand’s sex tourism and linking it to the global sex industry. This paper addresses transnational routes and networks of the global sex trade through Thai transsexual (male to female) sex workers who travel out of the country to Singapore for short periods to meet global demand. The research is based on in-depth interviews with 75 Thai transsexual sex workers who are working in districts such as Orchard Towers, Little India, and Geylang in Singapore. For some informants, Singapore is a final destination; for others, it is just a stop along the way to other places abroad. The findings show that the commercial sex trade involving these individuals is global in every sense, including the way it is funded, developed, structured, and organized.

description: The population is aging, and becoming more tech-savvy. The United Nations predicts that by 2050, one in six people in the world will be over age 65 (up from one in 11 in 2019), and this increases to one in four in Europe and Northern America. Meanwhile, the proportion of American adults over 65 who own a smartphone has risen 24 percentage points from 2013-2017, and the majority have Internet in their homes. Smart devices and smart home technology have profound potential to transform how people age, their ability to live independently in later years, and their interactions with their circle of care. Cognitive health is a key component to independence and well-being in old age, and smart homes present many opportunities to measure cognitive status in a continuous, unobtrusive manner. In this article, we focus on speech as a measurement instrument for cognitive health. Existing methods of cognitive assessment suffer from a number of limitations that could be addressed through smart home speech sensing technologies. We begin with a brief tutorial on measuring cognitive status from speech, including some pointers to useful open-source software toolboxes for the interested reader. We then present an overview of the preliminary results from pilot studies on active and passive smart home speech sensing for the measurement of cognitive health, and conclude with some recommendations and challenge statements for the next wave of work in this area, to help overcome both technical and ethical barriers to success.

description: Small-scale magnetic fields are not only the fundamental element of the solar magnetism, but also closely related to the structure of the solar atmosphere. The observations have shown that there is a ubiquitous tangled small-scale magnetic field with a strength of 60 $\sim$ 130\,G in the canopy forming layer of the quiet solar photosphere. On the other hand, the multi-dimensional MHD simulations show that the convective overshooting expels the magnetic field to form the magnetic canopies at a height of about 500\,km in the upper photosphere. However, the distribution of such small-scale ``canopies" in the solar photosphere cannot be rigorously constrained by either observations and numerical simulations. Based on stellar standard models, we identify that these magnetic canopies can act as a global magnetic-arch splicing layer, and find that the reflections of the solar p-mode oscillations at this magnetic-arch splicing layer results in significant improvement on the discrepancy between the observed and calculated p-mode frequencies. The location of the magnetic-arch splicing layer is determined at a height of about 630\,km, and the inferred strength of the magnetic field is about 90\,G. These features of the magnetic-arch splicing layer derived independently in the present study are quantitatively in agreement with the presence of small-scale magnetic canopies as those obtained by the observations and 3-D MHD simulations.

description: We have carried out calculations of electron transport through a metal-molecule-metal junction with metal nanoclusters taking the part of electrodes. We show that negative differential resistance peaks could appear in the current-voltage curves. The peaks arise due to narrow features in the electron density of states of the metal clusters. The proposed analysis is based on the ab initio computations of the relevant wave functions and energies within the framework of the density functional theory using NRLMOL software package.

description: Dielectronic recombination (DR) of singly charged ions is a reaction pathway that is commonly neglected in chemical models of molecular clouds. In this study we include state-of-the-art DR data for He$^+$, C$^+$, N$^+$, O$^+$, Na$^+$, and Mg$^+$ in chemical models used to simulate dense molecular clouds, protostars, and diffuse molecular clouds. We also update the radiative recombination (RR) rate coefficients for H$^+$, He$^+$, C$^+$, N$^+$, O$^+$, Na$^+$, and Mg$^+$ to the current state-of-the-art values. The new RR data has little effect on the models. However, the inclusion of DR results in significant differences in gas-grain models of dense, cold molecular clouds for the evolution of a number of surface and gas-phase species. We find differences of a factor of 2 in the abundance for 74 of the 655 species at times of $10^4$--$10^6$ years in this model when we include DR. Of these 74 species, 16 have at least a factor of 10 difference in abundance. We find the largest differences for species formed on the surface of dust grains. These differences are due primarily to the addition of C$^+$ DR, which increases the neutral C abundance, thereby enhancing the accretion of C onto dust. These results may be important for the warm-up phase of molecular clouds when surface species are desorbed into the gas phase. We also note that no reliable state-of-the-art RR or DR data exist for Si$^+$, P$^+$, S$^+$, Cl$^+$, and Fe$^+$. Modern calculations for these ions are needed to better constrain molecular cloud models.
