description: A new mechanism for the formation of cometary tails behind dense clouds or globules is discussed. Numerical hydrodynamical models show that when a dense shell of swept-up matter overruns a cloud, material in the shell is focussed behind the cloud to form a tail. This mode of tail formation is completely distinct from other methods, which involve either the removal of material from the cloud, or shadowing from a strong, nearby source of ionization. This mechanism is relevant to the cometary tails seen in planetary nebulae and to the interaction of superbubble shells with dense clouds.

Specific surface area in coloidal silica
Creators: name: Stolpe, Björn
Publisher: name: Zenodo
Year: 2020

description: The sample of colloidal silica is titrated with NaOH from pH 4 to pH 9, in a medium of 20 % NaCl(aq). A fraction of the OH- ions will bind to the surface of the silica particles, and the amount of “free” OH- contributing to the pH increase from 4 to 9 will therefore depend on the total surface area of the silica particles.

description: In today's panel topic on 'The Index of Prohibited Books: Liberty, License, and the Common Good,' the first part will be an argument that at least one form of censorship, namely that the Roman Catholic Church's Index Librorum Prohibitorum, actually fosters authentic human freedom. I will begin with a history of the Index, including its present authority, then present an argument demonstrating why the Index fosters freedom. I will close with a few remarks that I hope will provide a segue for my colleague's alternative view on censorship.
Prerainbow Oscillations in $^3$He Scattering from the Hoyle State of $^{12}$c and Alpha Particle Condensation

description: $^3$He+$^{12}$C scattering is studied in a coupled channel method by using a double folding model with microscopic wave functions of $^{12}$C. Experimental angular distributions in elastic and inelastic scattering to the $2^+$ (4.44 MeV), 0$^+_2$ (7.65 MeV) and 3$^-$ (9.63 MeV) states of $^{12}$C are well reproduced. It is found that the Airy minimum of the prerainbow oscillations for the Hoyle state is considerably shifted to a larger angle due to its dilute density distribution compared with that of the normal ground state in agreement with the idea of $α$ particle condensation.

Bridging the rural divide : an exploratory study of a medical school's rural applicants
Creators: name: Macala, Catherine
Publisher: name: University of British Columbia
Year: 2018

description: It is widely recognized that rural students are underrepresented in medical schools in Canada and many other countries. Some have argued that this underrepresentation stems from admissions selection biases. This study explores the relationship between the location of high school of graduation and applicant demographics, performance on several admissions measures, and incorporates a comparison of rural and non-rural applicant autobiographical submissions. For this study I allocated 1963 UBC medical school applicants from the 2014-15 application cycle into three categories (rural, regional and urban). Three primarily analyses were conducted: a comparison of demographic characteristics (age, gender, highest level of education earned at time of application, Aboriginal identity, and BC residency) across the applicant subgroups, a univariate and multivariate statistical analysis reviewing the relationship between location of high school of graduation and measures of performance in the admissions process, and a quantitative content analysis that compared rural, regional, and urban applicant non-academic and employment history experiences. Results suggest that subtle differences existed across the applicant subgroups. Primarily, rural applicants were more likely to be female, to identify as an Aboriginal person, to perform more poorly on the Medical College Admissions Test (MCAT), to work, and to mention employment in trades and forestry related professions than their non-rural peers. These differences, however, were unrelated to the rate at which applicants from the different subgroups advanced through the various stages of the admissions process. Because medical schools struggle to balance the goals and values of their programs with the metrics used to evaluate these traits and characteristics, results reinforce the importance of admissions policies designed to evaluate candidates in a background-appropriate manner so that a diversity of applicants, including those from rural areas, can adequately demonstrate their readiness for a career in medicine.

description: I'm the library assistant at St Hugh's College Library. The library closed at 5pm on 17th March, after which I worked from home for about 3 weeks until I was furloughed. From the day of closure until 22nd June, I didn't leave South Oxford. I never got on a bus, I didn't visit the city centre, and I didn't go to my library. So when I did return, it felt like a grand day out. Getting on the bus no longer represented a tiring commute through slow traffic, but a luxury. Even though I was just going to work, looking like a bank robber with my black face mask and sunglasses. And when I finally stepped back into my library, I was too happy to be intimidated by the hundreds of books I needed to return and shelve that day. I was completely alone in the library, which was rather spooky. Some of the reading rooms creak even when nobody is around, which was disconcerting, especially before I switched the lights on. But it meant I could stick my earphones in and zoom around doing the shelving without worrying about how much noise I was making. Tiring, but a great day.

description: We investigate next nearest neighbor correlations of the contact number in simulations of polydisperse, frictionless packings in two dimensions. We find that discs with few contacting neighbors are predominantly in contact with discs that have many neighbors and vice versa at all packing fractions. This counter-intuitive result can be explained by drawing a direct analogy to the Aboav-Weaire law in cellular structures. We find an empirical one parameter relation similar to the Aboav-Weaire law that satisfies an exact sum rule constraint. Surprisingly, there are no correlations in the radii between neighboring particles, despite correlations between contact number and radius.

description: (abridged) Recent spectroscopic and photometric observations show the existence of various generations of stars in GCs, differing in the abundances of products of H-burning at high temperatures (the main final product being He). It is important to study the connections between stars properties and He content. We consider here the about 1400 stars on the Red Giant Branch (RGB) observed with FLAMES@VLT in 19 Galactic GCs, part of out Na-O anticorrelation projet. Stars with different He are expected to have different temperatures (i.e. colours), slightly different [Fe/H], and different luminosity levels of the RGB bump. All these differences are small, but our study has the necessary precision, good statistics, and homogeneity to detect them. We also computed suitable sets of stellar models (BaSTI) for various assumptions about the initial helium content. Differences in observable quantities that can be attributed to variations in He content are generally detectable between stars of the Primordial (P, first-generation) and Extreme (E, second-generation) populations, but not between the Primordial and Intermediate ones (I). The only exception (differences are significant also between P and I populations) is NGC2808, where three populations are clearly separated also on the Main Sequence and the Horizontal Branch. The average enhancement in the He mass fraction Y between P and E stars is about 0.05-0.11, depending on the assumptions. The differences in Y, for NGC2808 alone, are about 0.11-0.14 between P and I stars, and about 0.15-0.19 between P and E stars, again depending on the assumptions. The RGB bump luminosity of first and second-generation stars has different levels; the implied Y difference is more difficult to quantify, but is in agreement with the other determinations.

Efficacy, safety and post-treatment comfort of cyanoacrylate as an adjunct to non-surgical periodontal therapy : a pilot randomized clinical trial
Creators: name: Chaturvedi, Rashi
Publisher: name: University of British Columbia
Year: 2018

description: Objectives: Non-surgical periodontal therapy (NSPT) can be associated with post-treatment complications of gingival tissue tenderness and teeth sensitivity that can negatively impact oral self-care thereby significantly affecting periodontal wound healing in its critical phase. The ineffectiveness of biofilm disruption can also further increase the sensitivity of gingival tissues and teeth resulting in patient’s reluctance in continuing regular oral self-care and professional therapy. This pilot split-mouth blinded randomized clinical trial assessed the efficacy of supra-gingival application of cyanoacrylate adhesive (PeriAcryl®90HV) in promoting periodontal wound healing and preventing increased sensitivity of teeth and gingival tissues following NSPT. Methods: 24 participants with active periodontal disease were recruited. Two selected quadrants with symmetrical disease were randomly divided into experimental and control arms and received NSPT. The experimental sites additionally received an application of cyanoacrylate adhesive (PeriAcryl®90HV) extending 1-2mm along gingival margins. Primary and secondary endpoints included clinical attachment level (CAL), bleeding on probing (BOP), probing depth (PD) and plaque score (PI), from baseline to the final visit at 6-8 weeks following NSPT. Furthermore, teeth sensitivity and pain and gingival tissue discomfort at baseline, 1-week and the final visit at 6-8 weeks following NSPT were ascertained using the visual analogue scale (VAS) and daily journaling. Receptiveness to future application of the cyanoacrylate adhesive was also evaluated using VAS. Results: The application of cyanoacrylate after NSPT resulted in no statistical changes between arms for CAL, PD, PI and sensitivity from baseline to the final visit at 6-8 weeks. BOP reduction was statistically significant (p=0.003*) in the experimental arm. The application of cyanoacrylate had no adverse events and was found highly acceptable (69.6%; n=16/23) by the subjects. Conclusions: The reduction of BOP in the study indicates, that the application of cyanoacrylate with its antimicrobial traits and treatment acceptance, may serve as a useful adjunct to NSPT in reducing gingival inflammation.

description: We study the possibility of detecting a signature of particle dark matter in the spectrum of gamma-ray photons from active galactic nuclei (AGNs) resulting from the scattering of high-energy particles in the AGN jet off of dark matter particles. We consider particle dark matter models in the context of both supersymmetry and universal extra-dimensions (UED), and we present the complete lowest-order calculation for processes where a photon is emitted in dark matter-electron and/or dark matter-proton scattering, where electrons and protons belong to the AGN jet. We find that the process is dominated by a resonance whose energy is dictated by the particle spectrum in the dark matter sector (neutralino and selectron for the case of supersymmetry, Kaluza-Klein photon and electron for UED). The resulting gamma-ray spectrum exhibits a very characteristic spectral feature, consisting of a sharp break to a hard power-law behavior. Although the normalization of the gamma-ray flux depends strongly on assumptions on both the AGN jet geometry, composition and particle spectrum as well as on the particle dark matter model and density distribution, we show that for realistic parameters choices, and for two prominent nearby AGNs (Centaurus A and M87), the detection of this effect is in principle possible. Finally, we compare our predictions and results with recent gamma-ray observations from the Fermi, H.E.S.S. and VERITAS telescopes.

description: As an effort to provide students the opportunity in enhancing design creativity in a personalized adaptive manner, an exercise program that address cognitive elements of creativity has been devised so that personalized needs in specific elements could be addressed. Being an exercise for creativity, the contents are rather unusual as students first deal with the program. Learning involves both cognitive and affective aspects of learning users in interacting with learning contents and interface. A learning user model includes assessment information as well as understanding on learners both static and dynamic characteristics. While cognitive aspects of a learning user would be rather static, affective aspects are dynamic in its nature. In the context of computer-assisted learning context of creative design capabilities, affective modeling of learners is being done using self-reporting format. Affective elements composed of joy, acceptance, fear, surprise, sadness, dislike, anger, and interest are used in the affective modeling in a simple training exercises for cognitive elements of creativity. While students conduct the exercises, they are asked to self-report their affective state using a simple diagram. Also, the entire exercise session is captured with students all activities including their facial expressions. From the images of learners captured during their activities, a human coder will also be able to develop the affective model. We conducted an experiment with students in interdisciplinary, integrated design where the exercise program for cognitive creativity elements with self-reporting of affective states was assigned between two simple conceptual design tasks. The experiment result indicates that the learning effects for fluency, flexibility and originality have been significant. We expect this research will help understand the affective state change and its relation with learning progression in creativity education.

description: As a DPhil student working with emerging viruses, it's been "all hands on deck" for our research group since the start of the pandemic. Staying productive while adapting to working from home is challenging, but being able to collaborate with great people across the globe has kept me motivated. I'm currently analysing epidemiological data from Ecuador, where I'm originally from, and helping our collaborators there to maintain their capacity to sequence viral genomes. This work is done alongside our contributions to the COVID-19 Data Working Group and HealthMap. It's an exhausting time to be a virus researcher, but also full of opportunities to learn and feel useful.

description: Aims. We seek a comprehensive analysis of all the information provided by the XMM-Newton satellite of the four Seyfert 1 galaxies ESO 359-G19, HE 1143-1810, CTS A08.12, and Mrk 110, including the UV range, to characterize the different components that are emitting and absorbing radiation in the vicinity of the active nucleus. Methods. The continuum emission was studied through the EPIC spectra by taking advantage of the spectral range of these cameras. The high-resolution RGS spectra were analyzed to characterize the absorbing and emission line features that arise in the spectra of the sources. All these data, complemented by information in the UV, are analyzed jointly in order to achieve a consistent characterization of the observed features in each object. Results. The continuum emission of the sources can be characterized either by a combination of a power law and a black body for the weakest objects or by two power law components for the brightest ones. The continuum is not absorbed by neutral or ionized material in the line of sight to any of these sources. In all of them we have identified a narrow Fe-Kalpha line at 6.4 keV. In ESO 559-G19 we also find an FeXXVI line at about 7 keV. In the soft X-rays band, we identify only one OVII line in the spectra of HE 1143-1810 and CTS A08.12, and two OVII-He alpha triplets and a narrow OVIII-Ly alpha emission line in Mrk 110. Conclusions. Not detecting warm material in the line of sight to the low state objects is due to intrinsically weaker or absent absorption in the line of sight and not to a low signal-to-noise ratio in the data. Besides this, the absence of clear emission lines cannot be fully attributed to dilution of those lines by a strong continuum.

Un magnifique spécimen, dressé, subcylindrique, haut de 13 centimètres, épais de 7, muni d'un large orifice cloacal subterminal, d'un diamètre de près de 2 centimètres. Sollas (25, p. 284) a fait l'histoire et donné une description magistrale de cette intéressante Lithistide. Je retrouve en très grande abondance dans l'échantillon d'Amboine les Thallophytes qu'il a découverts dans celui de Manille. Il s'agit donc d'un commensalisme habituel. Distribution. Formose; Manille; Amboine.

description: Polarization profiles are presented for 20 millisecond pulsars that are being observed as part of the Parkes Pulsar Timing Array project. The observations used the Parkes multibeam receiver with a central frequency of 1369 MHz and the Parkes digital filterbank pulsar signal-processing system PDFB2. Because of the large total observing time, the summed polarization profiles have very high signal/noise ratios and show many previously undetected profile features. Thirteen of the 20 pulsars show emission over more than half of the pulse period. Polarization variations across the profiles are complex and the observed position angle variations are generally not in accord with the rotating-vector model for pulsar polarization. Never-the-less, the polarization properties are broadly similar to those of normal (non-millisecond) pulsars, suggesting that the basic radio emission mechanism is the same in both classes of pulsar. The results support the idea that radio emission from millisecond pulsars originates high in the pulsar magnetosphere, probably close to the emission regions for high-energy X-ray and gamma-ray emission. Rotation measures were obtained for all 20 pulsars, eight of which had no previously published measurements.

description: Sydonops Picteti n. sp. PI. XVIII, fig, 2. Conservé dans l'alcool, un spécimen massif, globuleux, allongé, ferme, gris rosé; surface lisse, rude au toucher. Longueur 35 mm., largeur 18, épaisseur 15. Oscules nombreux, localisés à la partie supérieure dans une aire de 13 mm. de diamètre; ils sont béants, simples, petits (0,5 de diamètre au plus), entourés d'un rebord blanc. Pores en cribles sur les côtés et à la base de l'Éponge. Ectosome dur, épais, de m[n,8. Choanosome blanc jaunâtre. Spiculation. I. Mégasclères: 1. Oxes fusiformes, pointus, longs de 500 à 600 ( u, épais de 30 p au centre. 2. Ortho- trioenes à clades horizontaux presque dès leur origine, puis recourbés en dessous vers leur extrémité; rhabdome de même longueur que les oxes et de même épaisseur à sa base; cladome ne mesurant que 185 p de corde, les clades relativement grêles (23 jm d'épaisseur à la base) n'atteignant que 90 fx de longueur. 3. Anatrioenes, rhabdome épais de 10^, cladome ayant 70 jx de corde et 53 de sagitta; les clades sont grêles, pointus et vont s'écartant de plus en plus du rhabdome. 4. Protrioenes, rhabdome épais de 10 p, clades longs de 70 p. II. MicrosclèRES: 5. Sterrasters ellipsoïdales ou presque rondes, mesurant 97 u. sur 85; les actines, à leur extrémité, sont polygonales et armées d'épines. 6. Sphér asters somales à centrum épais, à actines courtes et tronquées; diamètre 4- 6 p. 7. Oxyasters choanosomales sans centrum marqué, à actines coniques, longues, assez grêles, épineuses, ordinairement peu nombreuses (7 à 12); dimensions moyennes des actines 17 à 20 p de longueur sur 2 p d'épaisseur à la base -/diamètre moyen des oxyasters 35 à 40 p. Un autre échantillon, desséché, dressé, rameux, à digitations épaisses enlaçant des fragments de Polypiers. Pores en cribles; pas d'oscules visibles, sterrasters mesurant 140 ^ sur 115. C'est peut-être de Sydonops nitida de Port-Jackson et Sydney que S. Picteti se rapproche le plus. Mais il existe ici des anatriaenes et des protrisenes; en outre, les sphérasters somales sont plus petites, les sterrasters notablement plus grosses, et les clades des orthotrisenes de moitié plus courts que dans l'espèce décrite par Sollas. Je me suis fait un devoir d'attacher à une Éponge de la collection d'Amboine le nom de feu C. Pictet, le compagnon d'exploration zoologique de M. Bedot dans l'Archipel Malais.

description: We demonstrate high-fidelity reversible transfer of quantum information from the polarisation of photons into the spin-state of an electron-hole pair in a semiconductor quantum dot. Moreover, spins are electrically manipulated on a sub-nanosecond timescale, allowing us to coherently control their evolution. By varying the area of the electrical pulse, we demonstrate phase-shift and spin-flip gate operations with near-unity fidelities. Our system constitutes a controllable quantum interface between flying and stationary qubits, an enabling technology for quantum logic in the solid-state.
An FPGA overlay architecture supporting software-like compile times during on-chip debug of high-level synthesis designs

description: High-Level Synthesis (HLS) promises improved designer productivity by allowing designers to create digital circuits targeting Field-Programmable Gate Arrays (FPGAs) using a software program. Widespread adoption of HLS tools is limited by the lack of an on-chip debug ecosystem that bridges the software to the generated hardware, and that addresses the challenge of long FPGA compile times. Recent work has presented an in-system debug framework that provides a software-like debug experience by allowing the designer to debug in the context of the original source code. However, like commercial on-chip debug tools, any modification to the on-chip debug instrumentation requires a system recompile that can take several hours or even days, severely limiting debug productivity. This work proposes a flexible debug overlay family that provides software-like debug turn-around times for HLS generated circuits (on the order of hundreds of milliseconds). This overlay is added to the design at compile time, and at debug time can be configured many times to implement specific debug scenarios without a recompilation. We propose two sets of debug capabilities, and their required architectural and CAD support. The first set form a passive overlay, the purpose of which is to provide observability into the underlying circuit and not change it. In this category, the cheapest overlay variant allows selective variable tracing with only a 1.7\% increase in area overhead from the baseline debug instrumentation, while the deluxe variant offers 2x-7x improvement in trace buffer memory utilization with conditional buffer freeze support. The second set of capabilities is control-based, where the overlay is leveraged to make rapid functional changes to the design. Supported functional changes include applying small deviations in the control flow of the circuit, or the ability to override signal assignments to perform efficient "what if'" tests. Our overlay is specifically optimized for designs created using an HLS flow; by taking advantage of information from the HLS tool, the overhead of the overlay can be kept low. Additionally, all the proposed capabilities require the designer to only interact with their original source code.

description: Explicit example, where the Hawking temperature of a black hole horizon is compatible with the black hole's Rényi entropy thermodynamic description, is constructed. It is shown that for every static, spherically symmetric, vacuum black hole space-time, a corresponding black hole solution can be derived, where the Hawking temperature is identical with the Rényi temperature, i.e. the one obtained from the Rényi entropy of the black hole via the 1st law of thermodynamics. In order to have this Hawking-Rényi type thermodynamic property, the black holes must be surrounded by an anisotropic fluid in the form of a Kiselev metric, where the properties of the fluid are uniquely determined by the mass of the black hole, $M$, and the Rényi parameter, λ. In the simplest Schwarzschild scenario, the system is found to be thermodynamically unstable, and the 3rd law of thermodynamics seems to play the role of a cosmic censor via placing an upper bound on the black hole's mass, by which preventing the black hole from loosing its horizon(s).

Chemical Abundances for 855 Giants in the Globular Cluster Omega Centauri (NGC 5139)

description: We present elemental abundances for 855 red giant branch (RGB) stars in the globular cluster Omega Centauri (w Cen) from spectra obtained with the Blanco 4m telescope and Hydra multifiber spectrograph. The sample includes nearly all RGB stars brighter than V=13.5, and span's w Cen's full metallicity range. The heavy alpha elements (Si, Ca, and Ti) are generally enhanced by ~+0.3 dex, and exhibit a metallicity dependent morphology that may be attributed to mass and metallicity dependent Type II supernova (SN) yields. The heavy alpha and Fe-peak abundances suggest minimal contributions from Type Ia SNe. The light elements (O, Na, and Al) exhibit >0.5 dex abundance dispersions at all metallicities, and a majority of stars with [Fe/H]>-1.6 have [O/Fe], [Na/Fe], and [Al/Fe] abundances similar to those in monometallic globular clusters, as well as O-Na, O-Al anticorrelations and the Na-Al correlation in all but the most metal-rich stars. A combination of pollution from intermediate mass asymptotic giant branch (AGB) stars and in situ mixing may explain the light element abundance patterns. A large fraction (27%) of w Cen stars are O-poor ([O/Fe]<0) and are preferentially located within 5-10' of the cluster center. The O-poor giants are spatially similar, located in the same metallicity range, and are present in nearly equal proportions to blue main sequence stars. This suggests the O-poor giants and blue main sequence stars may share a common origin. [La/Fe] increases sharply at [Fe/H]>-1.6, and the [La/Eu] ratios indicate the increase is due to almost pure s-process production.

description: We discuss the front propagation in the $A+B\rightarrow 2A$ reaction under subdiffusion which is described by continuous time random walks with a heavy-tailed power law waiting time probability density function. Using a crossover argument, we discuss the two scaling regimes of the front propagation: an intermediate asymptotic regime given by the front solution of the corresponding continuous equation, and the final asymptotics, which is fluctuation-dominated and therefore lays out of reach of the continuous scheme. We moreover show that the continuous reaction subdiffusion equation indeed possesses a front solution that decelerates and becomes narrow in the course of time. This continuous description breaks down for larger times when the front gets atomically sharp. We show that the velocity of such fronts decays in time faster than in the continuous regime.
