description: The challenge of learning a new concept, object, or a new medical disease recognition without receiving any examples beforehand is called Zero-Shot Learning (ZSL). One of the major issues in deep learning based methodologies such as in Medical Imaging and other real-world applications is the requirement of large annotated datasets prepared by clinicians or experts to train the model. ZSL is known for having minimal human intervention by relying only on previously known or trained concepts plus currently existing auxiliary information. This makes the ZSL applicable in many real-world scenarios, from unknown object detection in autonomous vehicles to medical imaging and unforeseen diseases such as COVID-19 Chest X-Ray (CXR) based diagnosis. We introduce a novel and broaden solution called Few/one-shot learning, and present the definition of the ZSL problem as an extreme case of the few-shot learning. We review over fundamentals and the challenging steps of Zero-Shot Learning, including state-of-the-art categories of solutions, as well as our recommended solution, motivations behind each approach, their advantages over each category to guide both clinicians and AI researchers to proceed with the best techniques and practices based on their applications. We then review through different datasets inducing medical and non-medical images, the variety of splits, and the evaluation protocols proposed so far. Finally, we discuss the recent applications and future directions of ZSL. We aim to convey a useful intuition through this paper towards the goal of handling complex learning tasks more similar to the way humans learn. We mainly focus on two applications in the current modern yet challenging era: coping with an early and fast diagnosis of COVID-19 cases, and also encouraging the readers to develop other similar AI-based automated detection/recognition systems using ZSL.

A follow-up study on data management and data sharing training in graduate education in the social sciences
Creators: name: Doonan, Ashley

Publisher: name: Zenodo
Year: 2018

description: Previous research suggests that many social science graduate programs are not providing data management or sharing training necessary for producing effective and ethical researchers. Understanding effective data management and the importance of data sharing is crucial and should be integrated into graduate education. This is especially important to the mission of data repositories and data libraries wishing to limit obstacles to data sharing and to respond to evolving research needs and data trends. The current study expands on our previous assessment of how social science graduate programs include formal and informal training in data sharing, management, and the use of repositories by conducting a syllabus review and analysis. Syllabi were gathered from databases such as OER Commons and from department websites from a random sample of American social science graduate programs. Text analysis was used to identify the inclusion of content within coursework. Consistent with our earlier work, we found that social science graduate programs often did not include content about data management or data sharing within their coursework. This new study provided insight into the need for supplemental coursework or certification in data management skills geared towards graduate students. We discuss potential strategies to implement this instruction.

description: A simple and efficient protocol for the synthesis of diaryl thioethers from the reaction of thiourea with a wide variety of aryl halides, including aryl iodides, aryl bromides and aryl chlorides in the presence of 3D hierarchical core-shell Fe3O4@NiO/Co3O4 microspheres has been described. This reaction enables the one-pot synthesis of diaryl thioethers in good to high yields using a non-toxic and magnetically separable catalyst in PEG-400 as an eco-friendly, safe, inexpensive and thermally stable solvent. Magnetic separation and reusability of catalyst for eight times without any significant loss of activity, the use of a commercially available, eco-friendly, cheap and chemically stable sulfur transfer agent and solvent, operational simplicity, environmentally benign, easier work-up procedure and cost efficiency make this method a promising candidate for potential applications in some organic reactions. The catalytic activity of Fe3O4@NiO/Co3O4 as a novel and inexpensive catalyst was investigated in the C-S cross coupling reaction.

Preserving the agricultural data story at the Ontario Agricultural College
Creators: name: Edwards, Michelle

Publisher: name: Zenodo
Year: 2018

description: Established in 1874, the Ontario Agricultural College (OAC) at the University of Guelph maintains a broad base of research activities, ranging from social and environmental conditions of rural communities, to health benefits of new foods, to more traditional plant and animal based agricultural research. Increasingly, OAC is recognized as the "research powerhouse" at the university, supported by the Ontario Ministry of Agriculture, Food and Rural Affairs and the three major federal funding agencies: Natural Sciences and Engineering Research Council of Canada (NSERC), Canadian Institutes of Health Research (CIHR), and Social Sciences and Humanities Research Council (SSHRC). With a broad spectrum of research, come a variety of research protocols, data formats, and outputs. Labs and research institutes develop their own data management processes, many without a preservation and access plan. To provide a cohesive approach to managing research projects, we developed a series of research data management (RDM) workshops for the OAC community. This series was piloted during the summer of 2017, and, based on its popularity, was offered again in fall 2017 and winter 2018. This presentation will discuss our tailored approach to teaching RDM along with impressions and feedback from participants. Connecting to the community through RDM is leading to hidden troves of historical agricultural data, allowing us to preserve the data story of OAC for almost 150 years.
Extracting high-level information from gamma-ray burst supernova spectra

description: Radiation transport codes are often used in astrophysics to construct spectral models. In this work we demonstrate how producing these models for a time series of data can provide unique information about supernovae (SNe). Unlike previous work, we specifically concentrate on the method for obtaining the best synthetic spectral fits, and the errors associated with the preferred model parameters. We demonstrate how varying the ejecta mass, bolometric luminosity ($L_{bol}$) and photospheric velocity ($v_{ph}$), affects the outcome of the synthetic spectra. As an example we analyze the photospheric phase spectra of the GRB-SN\,2016jca. It is found that for most epochs (where the afterglow subtraction is small) the error on $L_{bol}$ and $v_{ph}$ was $\sim$5\%. The uncertainty on ejecta mass and K.E. was found to be $\sim$20%, although this can be expected to dramatically decrease if models of nebular phase data can be simultaneously produced. We also demonstrate how varying the elemental abundance in the ejecta can produce better synthetic spectral fits. In the case of SN\,2016jca it is found that a decreasing $^{56}$Ni abundance as a function of decreasing velocity produces the best fit models. This could be the case if the $^{56}$Ni was sythesised at the side of the GRB jet, or dredged up from the centre of the explosion. The work presented here can be used as a guideline for future studies on supernovae which use the same or similar radiation transfer code.

description: A series of amino acid-derived chiral benzylthio alcohols have been prepared and characterized. A chiral mercapto alcohol derived from S-leucine has been used to form three chiral 2,4-disubstituted 1,3-oxathiolanes. One of these has been oxidized to the S-oxide and another to the S,S-dioxide. The cis and trans isomers have been characterized by 1H NMR in each case and it appears that thermal epimerisation at C-2 is possible at the sulfoxide oxidation state. The X-ray structure of major trans diastereomer of 2-phenyl-4-isobutyl-1,3-oxathiolane S,S-dioxide shows an envelope conformation with oxygen at the flap and an internal angle at sulfur of just 93.8°. This compound fragments upon flash vacuum pyrolysis at 700°C to give SO2, benzaldehyde and 4-methylpent-1-ene.

description: In this article we investigated the influence of the gravity induced higher dimensional operators on the issue of vacuum stability in a model containing two interacting scalar fields. As a framework we used the curved spacetime Effective Field Theory (cEFT) applied to the aforementioned system in which one of the scalars is heavy. After integrating out the heavy scalar we used the standard Euclidean approach to the obtained cEFT. Apart from analyzing the influence of standard operators like the non-minimal coupling to gravity and the dimension six contribution to the scalar field potential, we also investigated the rarely discussed dimension six contribution to the kinetic term and the new gravity induced contribution to the scalar quartic self-interaction.

The thrilling tales and derring-do of data librarians and digital scholarship
Creators: name: Whipple, Heather
Publisher: name: Zenodo
Year: 2018

description: Following Joque and Partlo (IASSIST Quarterly 38.2) and their respective discussions of different conceptualizations of data and of data librarians as translators, this paper considers the stories told about what data librarianship has been and where it might go, focusing on relationships within the library and on the growth and development of digital scholarship as a service or focus in libraries. While some may embrace the wide-open potential for what might constitute "data," others (including library colleagues) are just as likely to turn away out of disinterest or fear. Consequently, the most important stories we need to tell may be those that reveal data to be both exciting and familiar to resistant coworkers, researchers, and students. Digital scholarship shares some of the same challenges: confusion over what it might be and who is or isn't involved: arguably, just as everything can be data, these days everything can be at least partly digital (even those working with physical objects digital tools to share their stories). Like data, digital scholarship may benefit from curated narratives that clarify what and why it is worth libraries' time to support and promote, and how data librarians are part of that story.

description: Two-point correlation functions of spin operators in the minimal models ${\cal M}_{p,p'}$ perturbed by the field $Φ_{13}$ are studied in the framework of conformal perturbation theory. The first-order corrections for the structure functions are derived analytically in terms of gamma functions. Together with the exact vacuum expectation values of local operators, this gives the short-distance expansion of the correlation functions. The long-distance behaviors of these correlation functions in the case ${\cal M}_{2,2n+1}$ have been worked out using a form-factor bootstrap approach. The results of numerical calculations demonstrate that the short- and long-distance expansions match at the intermediate distances. Including the descendent operators in the OPE drastically improves the convergency region. The combination of the two methods thus describes the correlation functions at all length scales with good precision.

Hail data! A data preservation saga

Publisher: name: Zenodo
Year: 2018

description: This presentation will trace the history of the Alberta Hail Data Project and all the ongoing research data management steps involved in its collection, preservation, rescues, re-use, and enrichment for future use. Data "rescue and re-use" projects are a by-product of the rapidly-changing technological era in which we live and work. The Alberta Hail Project Meteorological and Barge-Humphries Radar Archive is an example of one such project. Between 1957 and 1991 the Alberta Research Council (ARC) collected valuable meteorological data in central Alberta. After 30 years of data collection, the project was defunded, original researchers departed, and the ARC was reorganized, putting the data immediately at risk. The University of Alberta Data Library and the ARC embarked on a project to rescue and preserve this "hail data". The data were archived, documented, and made accessible through a dedicated webpage. However, in 2015, the host server was shutting down, and the CDs holding the archived data had been stored in boxes for almost 15 years, putting the data at risk again. A new data re-rescue and reuse effort was undertaken.

Radio Polarization of the Young High-Magnetic-Field Pulsar PSR J1119-6127

Year: 2003
Subjects: subject: Astrophysics (astro-ph)

description: We have investigated the radio polarization properties of PSR J1119-6127, a recently discovered young radio pulsar with a large magnetic field. Using pulsar-gated radio imaging data taken at a center frequency of 2496 MHz with the Australia Telescope Compact Array, we have determined a rotation measure for the pulsar of +842 +/- 23 rad m^-2. These data, combined with archival polarimetry data taken at a center frequency of 1366 MHz with the Parkes telescope, were used to determine the polarization characteristics of PSR J1119-6127 at both frequencies. The pulsar has a fractional linear polarization of ~75% and ~55% at 1366 and 2496 MHz, respectively, and the profile consists of a single, wide component. This pulse morphology and high degree of linear polarization are in agreement with previously noticed trends for young pulsars (e.g., PSR J1513-5908). A rotating-vector (RV) model fit of the position angle (PA) of linear polarization over pulse phase using the Parkes data suggests that the radio emission comes from the leading edge of a conal beam. We discuss PSR J1119-6127 in the context of a recent theoretical model of pulsar spin-down which can in principle be tested with polarization and timing data from this pulsar. Geometric constraints from the RV fit are currently insufficient to test this model with statistical significance, but additional data may allow such a test in the future.

description: In the winter of 2017, academic librarians, information science professionals, data scientists, and stakeholders around the world realized great need to take immediate action regarding U.S. federal research data at risk from lack of long-term preservation and access. News about efforts and invitations to join forces for these data spread far and wide. These efforts exposed some fundamental considerations beyond the act of rescue. One year after the alarm call -- where are we and what have we learned? This presentation will take a look at different perspectives that permeate our understanding of data at risk within a profession at the intersection of so many disciplines. We will tell the ongoing story of the data rescue experience at Johns Hopkins and bring to light some of the many efforts that started. We will engage in a discussion about what comes next in an effort to understand not just what we did, but how we can frame sustainable future action.

description: We provide an overview of the Koopman operator analysis for a class of partial differential equations describing relaxation of the field variable to a stable stationary state. We introduce Koopman eigenfunctionals of the system and use the notion of conjugacy to develop spectral expansion of the Koopman operator. For linear systems such as the diffusion equation, the Koopman eigenfunctionals can be expressed as linear functionals of the field variable. The notion of inertial manifolds is shown to correspond to joint zero level sets of Koopman eigenfunctionals, and the notion of isostables is defined as the level sets of the slowest decaying Koopman eigenfunctional. Linear diffusion equation, nonlinear Burgers equation, and nonlinear phase-diffusion equation are analyzed as examples.

description: In this paper we provide approximate analytical analysis of stability of nonsingular inflationary chaotic-type cosmological models. Initial conditions for nonsingular solutions at the bounce correspond to dominance of potential part of the energy density of the scalar field over its kinetic part both within general relativity and gauge theories of gravity. Moreover, scalar field at the bounce exceeds the planckian value and on expansion stage these models correspond to chaotic inflation. Such solutions can be well approximated by explicitly solvable model with constant effective potential (cosmological term) and massless scalar field during the bounce and on stages of quasi-exponential contraction and expansion. Perturbative analysis shows that nonsingular inflationary solutions are exponentially unstable during contraction stage. This result is compared with numerical calculations.

description: The full two-body problem (F2BP) is often used to model binary asteroid systems, representing the bodies as two finite mass distributions whose dynamics are influenced by their mutual gravity potential. The emergent behavior of the F2BP is highly coupled translational and rotational mutual motion of the mass distributions. A large fraction of characterized binary asteroids appear to be at, or near, the doubly synchronous equilibrium, which occurs when both bodies are tidally-locked and in a circular co-orbit. Stable oscillations about this equilibrium can be shown, for the nonplanar system, to be combinations of seven fundamental frequencies of the system and the mutual orbit rate. The fundamental frequencies arise as the linear periods of center manifolds identified about the equilibrium which are heavily influenced by each body's mass parameters. We leverage these eight dynamical constraints to investigate the observability of binary asteroid mass parameters via dynamical observations. This is accomplished by deriving a relationship between the fundamental frequencies and mass parameters for doubly synchronous systems. This relationship allows us to show the sensitivity of the dynamics to changes in the mass parameters, first for the planar dynamics, and then for the nonplanar dynamics. In so doing we are able to predict the idealized estimation covariance of the mass parameters based on observation quality and define idealized observation accuracies for desired mass parameter certainties. We apply these tools to 617 Patroclus, a doubly synchronous Trojan binary and flyby target of the LUCY mission, as well as the Pluto and Charon system in order to predict mutual behavior

description: We calculate the contributions of the Kaluza-Klein (KK) modes to the gamma-penguins, gluon-penguins, gamma-magnetic penguins and chromomagnetic penguins in the Appelquist, Cheng and Dobrescu (ACD) model with one universal extra dimension. Together with our previous calculation of Z^0 penguin diagrams (See http://arxiv.org/abs/hep-ph/0212143) this allows to study the impact of the KK modes on the decays B -> X_s gamma, B -> X_s gluon, B -> X_s mu^+ mu^- and K_L -> pi^0 e^+ e^- and on the CP-violating ratio epsilon'/epsilon. For the compactification scale 1/R= 300 GeV the perturbative part of the branching ratio for B -> X_s mu^+ mu^- is enhanced by 12 % while the zero in the A_FB asymmetry is shifted from \hat s_0=0.162 to \hat s_0=0.142. The sizable suppressions of Br(B -> X_s gamma) ~ 20 % and Br(B -> X_s gluon) ~ 40 % could have interesting phenomenological implications on the lower bound on 1/R provided the experimental and theoretical uncertainties will be decreased. Similar comments apply to epsilon'/epsilon that is suppressed relative to the Standard Model expectations with the size of the suppression depending sensitively on the hadronic matrix elements. The impact on K_L -> pi^0 e^+ e^- is below 10 %. We point out a correlation between the zero \hat s_0 in the A_FB asymmetry and Br(B -> X_s gamma) that should be valid in most models with minimal flavour violation.

description: Dental cone-beam computed tomography (CBCT) is a powerful tool in clinical treatment planning, especially in a digital dentistry platform. Currently, the “as low as diagnostically acceptable” (ALADA) principle and diagnostic ability are a trade-off in most of the 3D integrated applications, especially in the low radio-opaque densified tissue structure. The CBCT benefits in comprehensive diagnosis and its treatment prognosis for post-operation predictability are clinically known in modern dentistry. In this paper, we propose a new algorithm called the selective anatomy analytic iteration reconstruction (SA2IR) algorithm for the sparse-projection set. The algorithm was simulated on a phantom structure analogous to a patient’s head for geometric similarity. The proposed algorithm is projection-based. Interpolated set enrichment and trio-subset enhancement were used to reduce the generative noise and maintain the scan’s clinical diagnostic ability. The results show that proposed method was highly applicable in medico-dental imaging diagnostics fusion for the computer-aided treatment planning, because it had significant generative noise reduction and lowered computational cost when compared to the other common contemporary algorithms for sparse projection, which generate a low-dosed CBCT reconstruction.

description: From the small scales of curbs, benches, and stairs, to the largest scale of buildings, and even edges of the city, skateboarders are continually imagining and inventing places of play. Even attune to the micro-scales of architecture such as texture, cracks, or the grain of materials - tactile experiences that become embodied by the skater. Architecture is a physical manifestation that positions bodies in space and time, and skateboarders are agents of spacial appropriation. Pushing the limits of play and form - challenging the intended use of objects in the urban environment. Skateboarding itself pushing the boundaries of who can participate. This project aims to investigate street skateboarders and their gaze in activating spaces. Looking at where they are skating, what are they skating, and what is the impact of how they use space at varying scales. Harnessing what I learnt from the skaters mindset - a lens in which they seek out opportunities for play. I want to rethink and reinvent the possibilities and opportunities for architecture and design to entice people to take advantage of play in public space as skaters do. The combination of the skater’s mindset which can be ignited in us all, and design, opening up a possibility for a new creation, to promote dynamic, playful behaviour to enrich public space.

description: We consider cosmological particle production in 1+1 dimensional string theory. The process is described most efficiently in terms of anomalies, but we also discuss the explicit mode expansions. In matrix cosmology the usual vacuum ambiguity of quantum fields in time-dependent backgrounds is resolved by the underlying matrix model. This leads to a finite energy density for the "in" state which cancels the effect of anomalous particle production.

Zitterbewegung of bosons

description: Zitterbewegung of massive and massless scalar bosons and a massive Proca (spin-1) boson is analyzed. The equations describing the evolution of the velocity and position of the scalar boson in the generalized Feshbach-Villars representation and the corresponding equations for the massive Proca particle in the Sakata-Taketani representation are equivalent to each other and to the well-known equations for the Dirac particle. However, Zitterbewegung does not appear in the Foldy-Wouthuysen representation. Since the position and velocity operators in the Foldy-Wouthuysen representation and their transforms to other representations are the quantum-mechanical counterparts of the corresponding classical variables, Zitterbewegung is not observable.

Preserving our electronic government information heritage

description: Access to government information is an integral part of our heritage in the United States. In the 1800s, the federal government began distributing publications to American libraries, and with the Printing Act of 1895, Congress created the Federal Depository Library Program (FDLP) with the purpose of distributing government information and data. Through the FDLP, our researchers have access to a wealth of government products, which provide in many cases the foundational materials for telling their research stories. In recent years, the rapidly changing information landscape has disrupted this workflow, especially as government information and data have become available in digital formats. Librarians and other information professionals from a variety of universities and organizations in the United States are undertaking a two year project to address national concerns regarding the Preservation of Electronic Government Information (PEGI) by cultural memory organizations for long term use. The focus of the PEGI project is at-risk government digital information of long term historical significance, especially for our future data storytellers. This session will provide attendees with an overview of the PEGI project and will encourage discussion about preservation of digital-born information and data that will help to inform the project's outcomes.

description: We present the results of a photometric and spectroscopic survey of cool M dwarf candidates in the young open cluster NGC 2547. Using the 2dF fiber spectrograph, we have searched for the luminosity at which lithium remains unburned in an attempt to constrain the cluster age. The lack of a population of individual lithium-rich objects towards the faint end of our sample places a very strong lower limit to the cluster age of 35 Myr. However, the detection of lithium in the averaged spectra of our faintest targets suggests that the lithium depletion boundary lies at 9.5 < M(I) < 10.0 and that the cluster age is < 54 Myr. The age of NGC 2547 judged from fitting isochrones to low-mass pre-main-sequence stars in colour-magnitude diagrams is 20-35 Myr using the same evolutionary models. The sense and size of the discrepancy in age determined by these two techniques is similar to that found in another young cluster, IC 2391, and in the low-mass pre main-sequence binary system, GJ 871.1AB. We suggest that the inclusion of rotation or dynamo-generated magnetic fields in the evolutionary models could reconcile the two age determinations, but only at the expense of increasing the cluster ages beyond that currently indicated by the lithium depletion. Alternatively, some mechanism is required that increases the rate of lithium depletion in young, very low-mass fully convective stars.

description: A well-known result of W. Ray asserts that if $C$ is an unbounded convex subset of a Hilbert space, then there is a nonexpansive mapping $T$: $C\to C$ that has no fixed point. In this paper we establish some common fixed point properties for a semitopological semigroup $S$ of nonexpansive mappings acting on a closed convex subset $C$ of a Hilbert space, assuming that there is a point $c\in C$ with a bounded orbit and assuming that certain subspace of $C_b(S)$ has a left invariant mean. Left invariant mean (or amenability) is an important notion in harmonic analysis of semigroups and groups introduced by von Neumann in 1929 \cite{Neu} and formalized by Day in 1957 \cite{Day}. In our investigation we use the notion of common attractive points introduced recently by S. Atsushiba and W. Takahashi.
