description: 蛾 is the kanji symbol for largely nocturnal beings that possess two large wings and are covered in microscopic scales (moths). 蛾 (Ga) is also the name of this recording of thirteen guided improvisations, which are inspired by the actions, sounds, and imagined worlds of other-than-human life forms. The improvisations invite the listener to contemplate the alien worlds that exist all around us but that nevertheless extend well beyond the borders of human perception and understanding.

The ensemble is comprised of Dylan van der Schyff (drums/percussion), Peggy Lee (cello), Andrew Saragossi (saxophones), and Andrew Doo (drums/percussion). The performers employ an arsenal of extended techniques, found objects, and unusual sonic juxtapositions, often blurring the boundaries of where one instrument ends and another begins.

This recording was made with minimal miking and with all performers in the same room (one mic per performer and a stereo pair). There were no overdubs, multiple takes, or editing of any kind. The music documented here is the totality produced by the session. Each track is named for a variety of moth.creditsreleased December 8, 2023

description: We study the upper projected bounds on the dark matter fraction in the form of the primordial black holes (PBHs) with a non-zero spin by using the absorption feature in the global 21-cm signal at redshift z ~ 17. The mass and spin are fundamental properties of a black hole, and they can substantially affect the evaporation rate of the black hole. The evaporating black hole can inject energy into the intergalactic medium and heat the gas. Subsequently, it can modify the absorption amplitude in the global 21-cm signal. Therefore, the absorption feature in the 21-cm signal can provide a robust bound on PBHs. We analyse the projected constraints on the dark matter fraction in the form of both spinning and non-spinning PBHs. The constraints are more stringent for spinning PBHs than non-spinning ones. We also compare these bounds with other observations and find the most stringent lower constraint on PBHs mass, which is allowed to constitute the entire dark matter to 6.7 x 10^17 g for extremal spinning PBHs.

String tension and removal of lattice coarsening effects in Monte Carlo Renormalization Group

description: We study the computation of the static quark potential under decimations in the Monte Carlo Renormalization Group (MCRG). Employing a multi-representation plaquette action, we find that fine-tuning the decimation prescription so that the MCRG equilibrium self-consistency condition is satisfied produces dramatic improvement at large distances. In particular, lattice coarsening (change of effective lattice spacing on action-generated lattices after decimation) is nearly eliminated. Failure to correctly tune the decimation, on the other hand, produces large coarsening effects, of order 50% or more, consistent with those seen in previous studies. We also study rotational invariance restoration at short distances, where no particular improvement is seen for this action.

description: The production of microchips is a complex and thus well documented process. Therefore, available textual data about the production can be overwhelming in terms of quantity. This affects the visibility and retrieval of a certain piece of information when it is most needed. In this paper, we propose a dynamic approach to interlink the information extracted from multisource production-relevant documents through the creation of a knowledge graph. This graph is constructed in order to support searchability and enhance user's access to large-scale production information. Text mining methods are firstly utilized to extract data from multiple documentation sources. Document relations are then mined and extracted for the composition of the knowledge graph. Graph search functionality is then supported with a recommendation use-case to enhance users' access to information that is related to the initial documents. The proposed approach is tailored to and tested on microchip design-relevant documents. It enhances the visibility and findability of previous design-failure-cases during the process of a new chip design.

description: We introduce the notion of quantum duplicates of an (associative, unital) algebra, motivated by the problem of constructing toy-models for quantizations of certain configuration spaces in quantum mechanics. The proposed (algebraic) model relies on the classification of factorization structures with a two-dimensional factor. In the present paper, main properties of this particular kind of structures are determined, and we present a complete description of quantum duplicates of finite set algebras. As an application, we obtain a classification (up to isomorphism) of all the algebras of dimension 4 (over an arbitrary field) that can be factorized as a product of two factors.

description: This paper argues that the UN might not be the ideal actor to get involved in armed conflicts if its aim is to decrease the occurrence of war. This claim is supported by a negative and a positive dimension. The negative dimension demonstrates that the UN has shown a debatable track record of sustainable results. The positive dimension claims that by providing support only to non-armed conflicts, the UN will create positive incentives for peaceful resolution and sustainably address the structural violence that lies at the root of conflict.

description: New HI images from the VLA Galactic Plane Survey (VGPS) show clear absorption features associated with the supernova remnant (SNR) G18.8+0.3. High-resolution $^{13}$CO images reveal that molecular clouds overlap the radio filaments of G18.8+0.3. The $^{13}$CO emission spectrum over the full velocity range in the direction of G18.8+0.3 shows two molecular components with high brightness-temperatureand three molecular components with low brightness-temperature, all with respective HI absorption. This implies that these clouds are in front of G18.8+0.3. In the HI images, the highest velocity absorption feature seen against the continuum image of G18.8+0.3 is at 129 km s$^{-1}$, which corresponds to the tangent point in this direction. This yields a lower distance limit of 6.9 kpc for G18.8+0.3. Absence of absorption at negative velocities gives an upper distance limit of 15 kpc. The broadened profile at 20$\pm$5 km s$^{-1}$ in the $^{13}$CO emission spectra is a strong indicator of a possible SNR/CO cloud interaction. Thus, G18.8+0.3 is likely to be at the distance of about 12 kpc. The upper mass limit and mean density of the giant CO cloud at 20$\pm$5 km s$^{-1}$ are \sim 6 \times 10^{5} M_{\odot} and \sim 2 \times 10^{2} cm^{-3}. We find an atomic hydrogen column density in front of G18.8+0.3 of $N_{HI}$ \sim 2 \times 10^{22} cm^{-2}. The ROSAT PSPC observations show a diffuse X-ray enhancement apparently associated with part of the radio shell of G18.8+0.3. Assuming an association, the unabsorbed flux is 2.2 \times10^{-12} erg cm^{-2} s^{-1}, suggesting an intrinsic luminosity of 3.6 \times 10^{34} erg s^{-1} for G18.8+0.3.

description: Based on First-principles calculation, we have investigated electronic structure of a ZrCuSiAs structured superconductor LaNiPO. The density of states, band structures and Fermi surfaces have been given in detail. Our results indicate that the bonding of the La-O and Ni-P is strongly covalent whereas binding property between the LaO and NiP blocks is mostly ionic. It's also found that four bands are across the Fermi level and the corresponding Fermi surfaces all have a two-dimensional character. In addition, we also give the band decomposed charge density, which suggests that orbital components of Fermi surfaces are more complicated than cuprate superconductors.

description: The unprecedented structural flexibility and diversity of inorganic frameworks of layered hybrid halide perovskites (LHHPs) rise up a wide range of useful optoelectronic properties thus predetermining the extraordinary high interest to this family of materials. Nevertheless, the influence of different types of distortions of their inorganic framework on key physical properties such as band gap has not yet been quantitatively identified. We provided a systematic study of the relationships between LHHPs' band gaps and six main structural descriptors of inorganic framework, including interlayer distances (dint), in-plane and out-of-plane distortion angles in layers of octahedra (θin,θout), layer shift factor (LSF), axial and equatorial Pb-I bond distances (dax,deq). Using the set on the selected structural distortions we realized the inverse materials design based on multi-step DFT and machine learning approach to search LHHPs with target values of the band gap. The analysis of calculated descriptors band gap dependences for the wide range of generated model structures of (100) single-layered LHHPs results in the following descending order of their importance:dint > θin > dax > LSFmin > θout > deq > LSFmax, and also implies a strong interaction value for some pairs of structural descriptors. Moreover,we found that the structures with completely different distortions of inorganic framework can have similar band gap, as illustrated by a number of both experimental and model structures.

description: We discuss several PT-symmetric deformations of superderivatives. Based on these various possibilities, we propose new families of complex PT-symmetric deformations of the supersymmetric Korteweg-de Vries equation. Some of these new models are mere fermionic extensions of the former in the sense that they are formulated in terms of superspace valued superfields containing bosonic and fermionic fields, breaking however the supersymmetry invariance. Nonetheless, we also find extensions, which may be viewed as new supersymmetric Korteweg-de Vries equation. Moreover, we show that these deformations allow for a non-Hermitian Hamiltonian formulation and construct three charges associated to the corresponding flow.

Two topics in Finance: 1. Welfare aspects of an asymmetric information rational expectations model : 2. Bond option pricing, empirical evidence

Publisher: name: University of British Columbia

description: In part 1 of this study I examine several models of competitive markets in which a group of uninformed traders uses the equilibrium price of a traded asset as an indirect source of information known to a group of informed traders. Four different models are compared in two homogeneous information cases plus one asymmetric information case, revealing a) an allocative efficiency benefit resulting from the opportunity to trade current consumption for future consumption, b) a 'dealer' benefit accruing to traders who are able to observe and act on demand fluctuations not apparent to other traders, c) a 'hedging' benefit accruing to all traders, and d) a loss of hedging benefits due to information dissemination before hedge trading can take place. The effect of an increase in precision of information given to informed traders is calculated for the above factors and for net welfare. In part 2, a two-factor model using the instantaneous rate of interest and the return on a consol bond to describe the term structure of interest rates - the Brennan-Schwartz model - is used to derive theoretical prices for American call and put options on U.S. government bonds and treasury bills. These model prices are then compared with market prices. The theoretical model used to value the debt options also provides hedge ratios which may be used to construct zero-investment portfolios which, in theory, are perfectly riskless. Several trading strategies based on these 'riskless' portfolios are examined.

description: We study the multi-spin entanglement for the 1D anisotropic XY model concentrating on the simplest case of three-spin entanglement. As compared to the pairwise entanglement, three-party quantum correlations have a longer range and they are more robust on increasing the temperature. We find regions of the phase diagram of the system where bound entanglement occurs, both at zero and finite temperature. Bound entanglement in the ground state can be obtained by tuning the magnetic field. Thermal bound entanglement emerges naturally due to the effect of temperature on the free ground state entanglement.

description: Bow River Falls is a collaborative ensemble recorded during a teaching residency at the Banff International Workshop in Jazz and Creative Music in Banff, Alberta. The ensemble includes trumpeter Dave Douglas, clarinetist Louis Sclavis, cellist Peggy Lee, and drummer/laptop musician Dylan van der Schyff. Reflecting the natural beauty of Banff, the musicians create atmospheric and organic pieces that reference '60s free jazz and contemporary classical chamber music – often recalling the iconic Ornette Coleman Quartets and the Art Ensemble of Chicago. The musicians utilize their instruments in unconventional ways, employing extended techniques to summoning growls, bleeps, and pinched squelches. Additionally, the laptop inclusions by van der Schyff are done live in the studio and have an organic quality, blending gurgling white noise, static, and other visceral found sounds with his acoustic percussion.

description: We obtain general expressions for the residual density of states, electrical conductivity and thermal conductivity for non-unitary superconductors due to impurity scattering. We apply the results to the so-called `B phase' of PrOs4Sb12, which we describe using a non-unitary gap function derived from symmetry considerations. The conductivity tensor has inequivalent diagonal components due to off-axis nodal positions which may be detectable in experiments.

description: The well-known experimentally observed \textit{sp}-derived Au(111) Shockley surface states with Rashba spin splitting are perfectly fit by an effective tight-binding model, considering a two-dimensional hexagonal lattice with $p_{z}$-orbital and nearest neighbor hopping only. The extracted realistic band parameters are then imported to perform the Landauer-Keldysh formalism to calculate nonequilibrium spin transport in a two-terminal setup sandwiching a Au(111) surface channel. Obtained results show strong spin density on the Au(111) surface and demonstrate (i) intrinsic spin-Hall effect, (ii) current-induced spin polarization, and (iii) Rashba spin precession, all of which have been experimentally observed in semiconductor heterostructures, but not in metallic surface states. We therefore urge experiments in the latter for these spin phenomena.

description: The fundamental example of Gerstenhaber algebra is the space $T_{poly}({\mathbb R}^d)$ of polyvector fields on $\mathbb{R}^d$, equipped with the wedge product and the Schouten bracket. In this paper, we explicitely describe what is the enveloping $G_\infty$ algebra of a Gerstenhaber algebra $\mathcal{G}$. This structure gives us a definition of the Chevalley-Harrison cohomology operator for $\mathcal{G}$. We finally show the nontriviality of a Chevalley-Harrison cohomology group for a natural Gerstenhaber subalgebra in $T_{poly}({\mathbb R}^d)$.

description: We report on the statistics of strong (W_r > 0.15 A) C IV absorbers at z=1.5-3.5 toward high-redshift gamma-ray bursts (GRBs). In contrast with a recent survey for strong Mg II absorption systems at z < 2, we find that the number of C IV absorbers per unit redshift dN/dz does not show a significant deviation from previous surveys using quasi-stellar objects (QSOs) as background sources. We find that the number density of C IV toward GRBs is dN/dz(z~1.5)= 2.2 +2.8/-1.4, dN/dz(z~2.5)= 2.3 +1.8/-1.1 and dN/dz(z~3.5)= 1.1 +2.6/-0.9. These numbers are consistent with previous C IV surveys using QSO spectra. Binning the entire dataset, we set a 95% c.l. upper limit to the excess of C IV absorbers along GRB sightlines at twice the incidence observed along QSO sightlines. Furthermore, the distribution of equivalent widths of the GRB and QSO samples are consistent with being drawn from the same parent population. Although the results for Mg II and C IV absorbers along GRB sightlines appear to contradict one another, we note that the surveys are nearly disjoint: the C IV survey corresponds to higher redshift and more highly ionized gas than the Mg II survey. Nevertheless, analysis on larger statistical samples may constrain properties of the galaxies hosting these metals (e.g. mass, dust content) and/or the coherence-length of the gas giving rise to the metal-line absorption.

description: There are several high-performance adaptive optics systems that deliver diffraction-limited imaging on ground-based telescopes, which renewed the interest of single-mode fiber (SMF) spectroscopy for exoplanet characterization. However, the fundamental mode of a telescope is not well matched to those of conventional SMFs. With the recent progress in asphere manufacturing techniques it may be possible to reshape the fundamental mode of a SMF into any arbitrary distribution. An optimization problem is setup to investigate what the optimal mode field distribution is and what the fundamental throughput limit is for SMF spectroscopy. Both single-object spectrographs and integral-field spectrographs are investigated. The optimal mode for single-object spectrographs is found to be the aperture function of the exit pupil, while for integral-field spectrographs the optimal mode depends on the spatial sampling of the focal plane. For dense sampling, a uniform mode is optimal, while for sparse sampling, the mode of a conventional SMF is near optimal. With the optimal fiber mode, high throughput (>80%) can be achieved when the focal plane is (super) Nyquist sampled. For the Nyquist sampled cases, the optimal mode has almost 20% more throughput than a conventional SMF.

description: We present our exhaustive exploration of the densest ternary sphere packings (DTSPs) for 45 radius ratios and 237 kinds of compositions, which is a packing problem of three kinds of hard spheres with different radii, under periodic boundary conditions by a random structure searching method. To efficiently explore DTSPs we further develop the searching method based on the piling-up and iterative balance methods [Koshoji et al., Phys. Rev. E 103, 023307 (2021)]. The unbiased exploration identifies diverse 38 putative DTSPs appearing on phase diagrams in which 37 DTSPs of them are discovered in the study. The structural trend of DTSPs changes depending especially on the radius of small spheres. In case that the radius of small spheres is relatively small, structures of many DTSPs can be understood as derivatives of densest binary sphere packings (DBSPs), while characteristic structures specific to the ternary system emerge as the radius of small spheres becomes larger. In addition to DTSPs, we reveal a lot of semi-DTSPs (SDTSPs) which are obtained by excluding DBSPs in the calculation of phase diagram, and investigate the correspondence of DTSPs and SDTSPs with real crystals based on the space group, showing a considerable correspondence of SDTSPs having high symmetries with real crystals including $\mathrm{Cu}_2 \mathrm{GaSr}$ and $\mathrm{ThCr}_2 \mathrm{Si}_2$ structures. Our study suggests that the diverse structures of DBSPs, DTSPs, and SDTSPs can be effectively used as structural prototypes for searching complex crystal structures.

description: The Sagnac effect is an important phase coherent effect in optical and atom interferometers where rotations of the interferometer with respect to an inertial reference frame result in a shift in the interference pattern proportional to the rotation rate. Here we analyze for the first time the Sagnac effect in a mesoscopic semiconductor electron interferometer. We include in our analysis Rashba spin-orbit interactions in the ring. Our results indicate that spin-orbit interactions increase the rotation induced phase shift. We discuss the potential experimental observability of the Sagnac phase shift in such mesoscopic systems.

description: Der Beitrag unternimmt im interdisziplinären Dialog von Kirchenrechts- und Liturgiewissenschaft eine praktisch-theologische Spurensuche zur Topographie des Beichtrituals. Schließlich hängen Beichtort, Feiergestalt und Sakramentsverständnis eng zusammen. Faktisch verhindert die rechtliche Beichtstuhlpflicht allerdings eine liturgische Feier des Sakraments, bei der die ekklesiale Dimension von Buße und Versöhnung angemessen zur Geltung kommt. Dies ist der historisch bedingte Preis für den vermeintlichen Schutz vor sexuellen Übergriffen bzw. entsprechenden Verdächtigungen, für den das Beichtgitter steht. In dieser Spannung können heutige Vorbehalte von Poenitenten gegenüber dem Beichtstuhl durchaus eine Chance zur Wiederentdeckung der Sakraltopographie sein und kann so auch bei der Einzelbeichte die ekklesiale Dimension der sakramentlichen Feier stärker zum Ausdruck gebracht werden.

description: Online users today are exposed to misleading and propagandistic news articles and media posts on a daily basis. To counter thus, a number of approaches have been designed aiming to achieve a healthier and safer online news and media consumption. Automatic systems are able to support humans in detecting such content; yet, a major impediment to their broad adoption is that besides being accurate, the decisions of such systems need also to be interpretable in order to be trusted and widely adopted by users. Since misleading and propagandistic content influences readers through the use of a number of deception techniques, we propose to detect and to show the use of such techniques as a way to offer interpretability. In particular, we define qualitatively descriptive features and we analyze their suitability for detecting deception techniques. We further show that our interpretable features can be easily combined with pre-trained language models, yielding state-of-the-art results.

description: The optimization of Binary Neural Networks (BNNs) relies on approximating the real-valued weights with their binarized representations. Current techniques for weight-updating use the same approaches as traditional Neural Networks (NNs) with the extra requirement of using an approximation to the derivative of the sign function - as it is the Dirac-Delta function - for back-propagation; thus, efforts are focused adapting full-precision techniques to work on BNNs. In the literature, only one previous effort has tackled the problem of directly training the BNNs with bit-flips by using the first raw moment estimate of the gradients and comparing it against a threshold for deciding when to flip a weight (Bop). In this paper, we take an approach parallel to Adam which also uses the second raw moment estimate to normalize the first raw moment before doing the comparison with the threshold, we call this method Bop2ndOrder. We present two versions of the proposed optimizer: a biased one and a bias-corrected one, each with its own applications. Also, we present a complete ablation study of the hyperparameters space, as well as the effect of using schedulers on each of them. For these studies, we tested the optimizer in CIFAR10 using the BinaryNet architecture. Also, we tested it in ImageNet 2012 with the XnorNet and BiRealNet architectures for accuracy. In both datasets our approach proved to converge faster, was robust to changes of the hyperparameters, and achieved better accuracy values.

description: Vierzig Prozent der gesamten Klimagas-Emissionen aus der deutschen Landwirtschaft gehen von trockengelegten Mooren aus. Die damit verbundenen gesellschaftlichen Kosten sind höher als der private betriebliche Nutzen. Die Wiedervernässung unserer Moorböden würde einen großen Beitrag zum Klima- und Gewässerschutz leisten. Außerdem würden mehr als 50 landwirtschaftlich nutzbare Pflanzenarten auch auf natürlich erhaltenen Moorböden gedeihen.

description: Previous literature in endogenous growth has been ignoring the fact that firms consider the interac- tion between its products through a portfolio approach while making decisions in innovation. In my model, a firm chooses optimal R&D expenses for radical and incremental innovations in each product line it has. From the portfolio perspective, ”volatility effects” and ”internal conflict” are introduced. Introduction of the first channel is adding anther benefit(besides direct profits) of radical innovation, but this marginal benefit is decreasing with firm size, while introduction of the second channel is adding another cost of radical innovation(besides the cost of research) and this marginal cost is increasing with firm size. The two channels discourage large firms from doing radical innovation. I constructed a framework where firms trade off two channels between increasing marginal success rate of radical innovation while choosing optimal share of radical innovation, which throw light on the phenomenan that large firms do less radical innovation. My simulation results show that volatility effects and internal conflict play a role in motivating small firms do more radical innovation while large firms do less.

description: In this paper we advance the simple analytic photometric redshift estimator for Type Ia supernovae (SNe Ia) proposed by Wang (2007), and use it to study simulated SN Ia data. We find that better than 0.5% accuracy in z_phot (with RMS[(z_phot-z_spec)/(1+z_spec)]<0.005) is possible for SNe Ia with well sampled lightcurves in three observed passbands (riz) with a signal-to-noise ratio of 25 at peak brightness, if the extinction by dust is negligible. The corresponding bias in z_phot (the mean of (z_phot-z_spec)) is 5.4\times 10^{-4}. If dust extinction is taken into consideration in the riz observer-frame lightcurves, the accuracy in z_phot deteriorates to 4.4%, with a bias in z_phot of 8.0\times 10^{-3}. Adding the g band lightcurve improves the accuracy in z_phot to 2.5%, and reduces the bias in z_phot to -1.5\times 10^{-3}. Our results have significant implications for the design of future photometric surveys of SNe Ia from both ground and space telescopes. Accurate and precise photometric redshifts boost the cosmological utility of such surveys.

a study of the major works of Hayashi Fumiko
Creators: name: Brown, Janice
Publisher: name: University of British Columbia
Year: 2010

description: This thesis provides a critical evaluation of certain selected works of Hayashi Fumiko and demonstrates the unique literary achievement of this important modern Japanese woman writer who is as yet little known in the West. This thesis contends that the element of struggle, so omnipresent in this writer's life and works, is the essence of her artistic vision. Herein, struggle is examined not only in terms of theme, characterization, imagery, and style but also as a major determining factor in the development and progression of narrative itself. Four principal struggles are discerned: (1) for art and beauty, (2) for love, (3) for maturity and independence, and (4) for survival. It is shown also that the first three of these categories of struggle belong to what in Hayashifs writings may be designated as the inner world of human feeling. This inner world is opposed to and in conflict with the outer world of hardship and necessity in which the struggle for survival takes place. Five major stages in the development of Hayashifs work are proposed, and representative works are discussed in each period to illustrate the developments and modifications of the struggle element. Chapter One, dealing with the period 1922-1930, discusses Hayashi's early poetry and her first major work, Hōrōki. Here, the inner struggle for art and beauty is affirmed amidst the hardship of the outer struggle for survival. Chapter Two discusses the period 1931-1934, and focuses on the short stories "Fūkin to sakana no machi'' and "Seihin no sho." In these works the inner struggles for love and for maturity are brought to the fore as Hayashi's early autobiographical fiction reaches the peak of lyrical expression. In Chapter Three, covering the period 1936-1942, Hayashi's change to "objective" fiction is examined, in particular her first full-length novella, Inazumaf in which the inner struggle is weakened and debilitated by the struggle with outside circumstances. Chapter Four covers the years 1946-1949, a period which represents Hayashi's full maturity. In Ukigumo, her masterpiece, the forces of the inner struggle assume demonic proportions, overpowering the outward struggle for survival and success. In Chapter Five, Hayashi's final years, 1950-1951, are examined. Here, in Meshi, the author attempts to reconcile the dichotomies of the inner and outer elements of struggle as she portrays the lives of ordinary people, striving to find self-fulfillment in the modern world. The thesis concludes that the element of struggle provides a primary tool by which the works of this author can be fully appraised and appreciated. By providing an explication of this element, this thesis not only offers an insight into the mechanisms of Hayashi's genius but also presents a much-needed introduction to and interpretation of this writer's work.

description: Datasets in the computer vision academic research community are primarily static. Once a dataset is accepted as a benchmark for a computer vision task, researchers working on this task will not alter it in order to make their results reproducible. At the same time, when exploring new tasks and new applications, datasets tend to be an ever changing entity. A practitioner may combine existing public datasets, filter images or objects in them, change annotations or add new ones to fit a task at hand, visualize sample images, or perhaps output statistics in the form of text or plots. In fact, datasets change as practitioners experiment with data as much as with algorithms, trying to make the most out of machine learning models. Given that ML and deep learning call for large volumes of data to produce satisfactory results, it is no surprise that the resulting data and software management associated to dealing with live datasets can be quite complex. As far as we know, there is no flexible, publicly available instrument to facilitate manipulating image data and their annotations throughout a ML pipeline. In this work, we present Shuffler, an open source tool that makes it easy to manage large computer vision datasets. It stores annotations in a relational, human-readable database. Shuffler defines over 40 data handling operations with annotations that are commonly useful in supervised learning applied to computer vision and supports some of the most well-known computer vision datasets. Finally, it is easily extensible, making the addition of new operations and datasets a task that is fast and easy to accomplish.

description: The survey content was based on a review of the literature and included a financial literacy assessment portion that was adapted from the validated Financial Industry Regulatory Authority (FINRA) Financial Literacy Quiz. To quantify debt burden, students estimated anticipated education-related debt in 1 of 4 categories: no debt, $1–99,999; $100,000–$199,999; and $200,000 or more. Financial stress was assessed with the question “Do you worry about your current financial status?”, with three possible responses: “not concerned”, “somewhat concerned”, and “very concerned”. The racial and ethnic populations considered “underrepresented in medicine” (URiM) were based on the definition used by the AAMC: “those racial and ethnic populations that are underrepresented in the medical profession relative to their numbers in the general population.” The options included in this survey were American Indian or Alaskan Native, Black or African American, Latino, and Native Hawaiian or Pacific Islander.

description: We provide several formulas that determine the optimal number of entangled bits (ebits) that a general entanglement-assisted quantum code requires. Our first theorem gives a formula that applies to an arbitrary entanglement-assisted block code. Corollaries of this theorem give formulas that apply to a code imported from two classical binary block codes, to a code imported from a classical quaternary block code, and to a continuous-variable entanglement-assisted quantum block code. Finally, we conjecture two formulas that apply to entanglement-assisted quantum convolutional codes.

description: Photometric and spectroscopic analyses of the intermediate-luminosity Type Ib supernova (SN) 2015ap and of the heavily reddened Type Ib SN~2016bau are discussed. Photometric properties of the two SNe, such as colour evolution, bolometric luminosity, photospheric radius, temperature, and velocity evolution, are also constrained. The ejecta mass, synthesised nickel mass, and kinetic energy of the ejecta are calculated from their light-curve analysis. We also model and compare the spectra of SN~2015ap and SN~2016bau at various stages of their evolution. The P~Cygni profiles of various lines present in the spectra are used to determine the velocity evolution of the ejecta. To account for the observed photometric and spectroscopic properties of the two SNe, we have computed 12\,$M_\odot$ zero-age main sequence (ZAMS) star models and evolved them until the onset of core collapse using the publicly available stellar-evolution code {\tt MESA}. Synthetic explosions were produced using the public version of {\tt STELLA} and another publicly available code, {\tt SNEC}, utilising the {\tt MESA} models. {\tt SNEC} and {\tt STELLA} provide various observable properties such as the bolometric luminosity and velocity evolution. The parameters produced by {\tt SNEC}/{\tt STELLA} and our observations show close agreement with each other, thus supporting a 12\,$M_\odot$ ZAMS star as the possible progenitor for SN~2015ap, while the progenitor of SN~2016bau is slightly less massive, being close to the boundary between SN and non-SN as the final product.
