description: We present advances made in the Large Area Picosecond Photodetector (LAPPD), an 8" $\times$ 8" microchannel plate photomultiplier tube (MCP-PMT), since pilot production was initiated at Incom, Inc. in 2018. The Gen-I LAPPD utilizes a stripline anode for direct charge readout. The novel Gen-II LAPPD employs an internal resistive thin-film which capacitively couples to a customizable external signal readout board, streamlining production. The Gen-II LAPPD, with an active area of 373 cm$^2$, is capable of high single photoelectron (PE) gain of $\sim$10$^7$, low dark rates ($\sim$1 kHz/cm$^2$), single PE timing resolution of $\sim$65 ps, and $\mathcal{O}$(mm) position resolution. Coupled with a UV-grade fused silica window, the LAPPD features a high quantum efficiency (QE) bialkali photocathode of $>$30% with spectral response down to $\sim$165 nm. The LAPPD is an excellent candidate for electromagnetic calorimeter (ECAL) timing layers, photon-based neutrino detectors, high energy collider experiments, medical imaging systems, and nuclear non-proliferation applications.

description: We address the highly debated issue of constraining the gamma-ray emission region in blazars from cross-correlation analysis using discrete correlation function between radio and gamma-ray light curves. The significance of the correlations is evaluated using two different approaches: simulating light curves and mixed source correlations. The cross-correlation analysis yielded 26 sources with significant correlations. In most of the sources, the gamma-ray peaks lead the radio with time lags in the range +20 and +690 days, whereas in sources 1633+382 and 3C 345 we find the radio emission to lead the gamma rays by -15 and -40 days, respectively. Apart from the individual source study, we stacked the correlations of all sources and also those based on sub-samples. The time lag from the stacked correlation is +80 days for the whole sample and the distance travelled by the emission region corresponds to 7 pc. We also compared the start times of activity in radio and gamma rays of the correlated flares using Bayesian block representation. This shows that most of the flares at both wavebands start at almost the same time, implying a co-spatial origin of the activity. The correlated sources show more flares and are brighter in both bands than the uncorrelated ones.

Growth index of matter perturbations in running vacuum models

subject: FOS: Physical sciences

description: We derive for the first time the growth index of matter perturbations of the FLRW flat cosmological models in which the vacuum energy depends on redshift. A particularly well motivated model of this type is the so-called quantum field vacuum, in which apart from a leading constant term $Λ_0$ there is also a $H^{2}$-dependence in the functional form of vacuum, namely $Λ(H)=Λ_{0}+3ν(H^{2}-H^{2}_{0})$. Since $|ν|\ll1$ this form endows the vacuum energy of a mild dynamics which affects the evolution of the main cosmological observables at the background and perturbation levels. Specifically, at the perturbation level we find that the growth index of the running vacuum cosmological model is $γ_{Λ_{H}} \approx \frac{6+3ν}{11-12ν}$ and thus it nicely extends analytically the result of the $Λ$CDM model, $γ_Λ\approx 6/11$.

The inverse spatial Laplacian of spherically symmetric spacetimes

Publisher: name: arXiv
Year: 2016
Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)
subject: FOS: Physical sciences

description: In this paper we derive the inverse spatial Laplacian for static, spherically symmetric backgrounds by solving Poisson's equation for a point source. This is different from the electrostatic Green function, which is defined on the four dimensional static spacetime, while the equation we consider is defined on the spatial hypersurface of such spacetimes. This Green function is relevant in the Hamiltonian dynamics of theories defined on spherically symmetric backgrounds, and closed form expressions for the solutions we find are absent in the literature. We derive an expression in terms of elementary functions for the Schwarzschild spacetime, and comment on the relation of this solution with the known Green function of the spacetime Laplacian operator. We also find an expression for the Green function on the static pure de Sitter space in terms of hypergeometric functions.

Origin of lowered magnetic moments in epitaxially strained thin films of multiferroic Bi$_2$FeCrO$_6$

description: We have investigated the effect of epitaxial strain on the magnetic properties and $B$-site cation ordering in multiferroic Bi$_2$FeCrO$_6$ (001) thin films using a density-functional theory approach. We find that in thin films with rock-salt ordering of Fe and Cr the ground state is characterised by C-type anti-ferromagnetic (AFM) order. This is in contrast to the bulk form of the material which was predicted to be a ferrimagnet with G-type AFM order. Furthermore, the cation ordered thin-films undergo a transition with epitaxial strain from C to A-type AFM order. Other magnetic orders appear as thermally accessible excited states. We also find that $B$-site cation disordered structures are more stable in coherent epitaxial strains thereby explaining the lowered magnetic moments observed in these samples at room temperature. Strain varies both the sign as well as strength of the Fe-Cr superexchange coupling resulting in a very interesting phase diagram for Bi$_2$FeCrO$_6$ thin films.

description: Magnetic topological quantum materials are attracting considerable attention owing to their potential technological applications. However, only a small number of these materials have been experimentally realized, thereby giving rise to the need for new stable magnetic topological quantum materials. Magnetism and spin-orbit coupling, two essential ingredients of the oxide materials, lead to various topological transport phenomena such as the anomalous Hall and anomalous Nernst effects, which can be significantly enhanced by designing an electronic structure with a large Berry curvature. In that respect, double perovskites with the general formula A$_2$BB'O$_6$ with an alternating ordered arrangement of two transition metal sites, B(3d) and B'(4d/5d), present attractive possibilities as they are robustly stable against oxidation under ambient conditions and versatile. These double perovskites also offer a high energy scale for magnetism as well as strong spin-orbit coupling with a high magnetic ordering temperature. Here, using first-principles density functional theory calculations, we present a comprehensive study of the intrinsic anomalous transport for 3d-4d/5d based cubic and tetragonal stable double perovskite (DP) compounds. A few of the DPs exhibit a very large anomalous Hall effect with a distinct topological band crossing in the vicinity of the Fermi energy. Our results show the importance of symmetries, particularly the mirror planes, as well as the clean topological band crossing near the Fermi energy, which is primarily contributed by the 5d-t$_{2g}$ for large anomalous Hall and Nernst effects.

description: At first glance, it is tempting to consider Canberra and Ottawa as similar ''political capitals," to use Peter Hall's classification. They are both capitals of Commonwealth countries and products of political compromises in federal states. Both of them grew rapidly after World War II. Yet a closer look at the planning of the two cities reveals more differences than similarities. Canadian visitors to Canberra find a city quite unlike any in their own country.

Some notes on the regular graph defined by Schmidt and Summerer and uniform approximation

description: Within the study of parametric geometry of numbers W. Schmidt and L. Summerer introduced so-called regular graphs. Roughly speaking the successive minima functions for the classical simultaneous Diophantine approximation problem have a very special pattern if the vector $\underlineζ$ induces a regular graph. The regular graph is in particular of interest due to a conjecture by Schmidt and Summer concerning classic approximation constants. This paper aims to provide several new results on the behavior of the successive minima functions for the regular graph. Moreover, we improve the best known upper bounds for the classic approximation constants $\hat{w}_{n}(ζ)$, valid uniformly for all transcendental $ζ$, provided that the Schmidt-Summerer conjecture is true.

An almost deterministic cooling by measurements

Publisher: name: arXiv
Year: 2023
Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: Nondeterministic measurement-based techniques are efficient in reshaping the population distribution of a quantum system but suffer from a limited success probability of holding the system in the target state. To reduce the experimental cost, we exploit the state-engineering mechanisms of both conditional and unconditional measurements and propose a two-step protocol assisted by a qubit to cool a resonator down to the ground state with a near-unit probability. In the first step, the unconditional measurements on the ancillary qubit are applied to reshape the target resonator from a thermal state to a reserved Fock state. The measurement sequence is optimized by reinforcement learning for a maximum fidelity. In the second step, the population on the reserved state can be faithfully transferred in a stepwise way to the resonator's ground state with a near-unit fidelity by the conditional measurements on the qubit. Intrinsic nondeterminacy of the projection-based conditional measurement is effectively inhibited by properly spacing the measurement sequence, which makes the Kraus operator act as a lowering operator for neighboring Fock states. Through dozens of measurements, the initial thermal average occupation of the resonator can be reduced by five orders in magnitude with a success probability over $95\%$.

description: This paper seeks to describe the process by which a database-centric web application was redesigned and rewritten to take advantage of Apache's Lucene - an open-source information retrieval software library written in the Java programming language. After the implementation of a Lucene-based text index of "semi-structured data", a college radio station's card catalog application was able to deliver higher-quality search results in significantly less time than it was able to do using just a relational database alone. Additionally, the dramatic improvements in speed and performance even allowed the search results interface to be redesigned and enhanced with an improved pagination system and new features such as faceted search/filtering.

description: Literature review
description: Purpose – The world’s population is expected to increase by 30 percent to 10bn people by 2050 and with 70 percent of the earth’s surface covered by water aquaculture will play an important role in producing food for the future. The paper aims to discuss this issue. Design/methodology/approach – While Canada has the longest coastline in the world by far (202,080 km) with 80,000 km of marine coastline capable of supporting aquaculture and fisheries, it ranks only 25th in terms of world aquaculture production. The reasons are many and varied, and this review examines statistical reports and publications to trace the beginnings of the aquaculture sector in Canada, and highlights some areas of strength and potential, and the challenges for future growth and expansion. Findings – Currently, less than 1 percent of the 3.8m hectares of freshwater and marine areas that are considered suitable for seafood (i.e. finfish, shellfish and aquatic plants) production are being farmed so Canada has an ocean of opportunity to be a leader in world aquaculture production in the future. Originality/value – The review highlights the need for a national strategic plan to increase aquaculture production in Canada and the need to simplify the current complex regulatory framework that has resulted in significant uncertainties and delays that have limited growth in this sector. The review highlights the potential and interest to triple current production while fostering greater involvement of First Nation communities.

description: We present HI imaging of the galaxy group IC 1459 carried out with six antennas of the Australian SKA Pathfinder equipped with phased-array feeds. We detect and resolve HI in eleven galaxies down to a column density of $\sim10^{20}$ cm$^{-2}$ inside a ~6 deg$^2$ field and with a resolution of ~1 arcmin on the sky and ~8 km/s in velocity. We present HI images, velocity fields and integrated spectra of all detections, and highlight the discovery of three HI clouds -- two in the proximity of the galaxy IC 5270 and one close to NGC 7418. Each cloud has an HI mass of $10^9$ M$_\odot$ and accounts for ~15% of the HI associated with its host galaxy. Available images at ultraviolet, optical and infrared wavelengths do not reveal any clear stellar counterpart of any of the clouds, suggesting that they are not gas-rich dwarf neighbours of IC 5270 and NGC 7418. Using Parkes data we find evidence of additional extended, low-column-density HI emission around IC 5270, indicating that the clouds are the tip of the iceberg of a larger system of gas surrounding this galaxy. This result adds to the body of evidence on the presence of intra-group gas within the IC 1459 group. Altogether, the HI found outside galaxies in this group amounts to several times $10^9$ M$_\odot$, at least 10% of the HI contained inside galaxies. This suggests a substantial flow of gas in and out of galaxies during the several billion years of the group's evolution.

description: The purpose of the study was to analyse the level of stress among men and women of undergraduate students who are not regularly involved in physical exercises.187 were females, and 131 were males. A straightforward randomised sampling technique was used to choose male and female first-year undergraduate students who met the inclusion requirements. For randomisation, a random number generator was employed. The nature of the study was explained to the included subjects in the language that they could understand the best. Subjects who were willing to participate in the study provided written informed consent, which each subject duly signed. Only the research team had access to the consent form and all other participant identifiers, which were kept private and secure. Perceived Stress scale was used to assess the stress. Standard descriptive statistics were obtained. Independent t-test was used to identify the difference between males and females on stress level. It was evident that the female students have high level of stress when compared to men students.

description: It is shown that the theory of causal fermion systems gives rise to a novel mechanism for dark matter and dark energy. This mechanism is first worked out for cubical subsets of Minkowski space with periodic boundary conditions. Then it is studied in Friedmann–Lemaître–Roberson–Walker spacetimes. The magnitude of the effect scales like one over the lifetime of the Universe squared. In contrast to most models of dark matter and dark energy, our mechanism does not postulate any new particles. Instead, it is a result of the collective behavior of all the wave functions which form the Dirac sea, needed in order to arrange correlated initial and end quantum states of the Universe.

description: In the middle of the twentieth century, Brazil went through a pivotal period in its history. On the political front, Brazilians tried to improve and consolidate their democratic institutions so as to bring the country closer to the leading nations of the free world. In the area of economics, the government strengthened and implemented a program to substitute imported goods through the creation of a large and sophisticated industrial park. It also invested heavily in the development of complementary economic infrastructure, and began to conceive social policies to eliminate poverty. In short, with economic development, a strengthened political structure, and a commitment to social justice, Brazil intended to improve its domestic profile and play a more assertive role in a changing world.

description: We report re-analyses of the Suzaku observations of the Galactic supernova remnant (SNR), G272.2$-$3.2, for which the previous studies were limited below 3 keV. With careful data reduction and background subtraction, we discover the K-shell lines of Ar, Ca, and Fe above 3 keV. The X-ray spectrum of G272.2$-$3.2 consists of two components, a low-temperature collisional ionization equilibrium (CIE) plasma ($kT_{\rm e} \sim 0.2$ keV) and a high-temperature non-equilibrium ionization (NEI) plasma ($kT_{\rm e} = 0.6$-$3$ keV). The CIE plasma has solar abundances over the entire area, hence it would originate from the interstellar medium. On the other hand, the abundances of the NEI plasma increase toward the inner region, suggesting the ejecta origin. The line center energy of the Fe K-shell emission ($\sim 6.4$ keV) suggests that the ejecta are recently heated by the reverse shock, a common feature in Type Ia SNRs.

description: The interdisciplinary approach of combining expertise in environmental, geochemical, civil engineering and material sciences realizes a new level of in-depth process understanding of the prevailing biophysicochemical reaction mechanisms occurring at mineral-fluid interfaces in various anthropogenic settings such as (geo)technical and construction surroundings. Proposed investigations may focus on the interaction of solid - liquid - gas interfaces, on proxy-based forensic reconstruction and adaptation of variable and possibly unfavorable environmental and operating conditions of different spatial and temporal scales. The advanced process understanding of mineral – environment (abiotic and/or biotic) interactions, combined with newly developed and state-of-the-art environmental monitoring tools (e.g. sensor-based high-resolution data acquisition) enables the target-oriented and customized optimization and development of sustainable material alteration prevention strategies (e.g. advanced inorganic binder systems) and durable mineral-based construction materials, as well as measures against unwanted mineral formation (e.g. plugging of geological reservoirs or drainage systems). In this scope, contributions on advanced environmental monitoring strategies and tools (e.g. sensor systems, isotope/elemental tracers), processes at critical fluid-solid interfaces and high-resolution chemical, (micro-)biological, mineralogical and micro-/nanostructural analytics (e.g. FEG-EPMA, X-ray microtomography), as well as field-based testing, laboratory experiments and modelling approaches are cordially invited.

Information-seeking behavior

description: Classics, the study of the ancient Greek and Roman civilizations, is a field that thrives on the old and the long past. Classicists may often be stereotyped by library science scholars as being resistant to technology. As academic libraries are turning to digital materials at an increasing rate, it is likely that it will soon become necessary for classicists to do more research online. Therefore, it becomes increasingly important for academic librarians to consider the current information seeking behavior of classicists, specifically how they use print and electronic resources for teaching and research. This knowledge will help librarians to design more effective instruction, collection development, and support for this group. This study will examine the information seeking behavior of the faculty and graduate students in the Classics Department at the University of North Carolina at Chapel Hill (UNC-CH) and suggest ways of optimizing the collecting of print and electronic resources for classicists.

description: We consider a game where a finite number of retailers choose a location, given that their potential consumers are distributed on a network. Retailers do not compete on price but only on location, therefore each consumer shops at the closest store. We show that when the number of retailers is large enough, the game admits a pure Nash equilibrium and we construct it. We then compare the equilibrium cost borne by the consumers with the cost that could be achieved if the retailers followed the dictate of a benevolent planner. We perform this comparison in term of the price of anarchy, i.e., the ratio of the worst equilibrium cost and the optimal cost, and the price of stability, i.e., the ratio of the best equilibrium cost and the optimal cost. We show that, asymptotically in the number of retailers, these ratios are bounded by two and one, respectively.

Fair use (Copyright)

description: Using content analysis, this study examines what information on copyright and fair use academic libraries offer users through their websites, with a particular focus on undergraduate information needs. This was done by analyzing the websites of thirty-three academic libraries, selected from the list of the member institutions of the Association of Research Libraries. The results of this exploratory study show that while most libraries provide general educational information on copyright, they do not fully explain all aspects of copyright and fair use. Particularly lacking are resources that help undergraduate creators understand what they can and cannot do under fair use. For academic libraries to support undergraduates in becoming effective information users and creators, they should offer resources that fully educate undergraduate students on their rights and responsibilities as both creators and consumers of information.

description: This study describes an online survey of institutions which host digital archival collections on Flickr outside of the Flickr Commons. The survey was conducted to determine the experience of these institutions with Flickr in terms of usage statistics, user interaction, and assessment. The results from the survey were also used to determine factors which contribute to the success of a Flickr collection.  The majority of the eighty-nine institutions which responded to the survey reported satisfaction with Flickr and stated that they had achieved their goals. However, many respondents reported low usage or did not know the usage, which indicates weak evaluation. Factor analysis revealed that age, metadata creation, enabled social media tools, and number of staff members with time dedicated to the collection all related to the success of these collections. Recommendations for increasing usage are included.
Energy dependence of localization with interactions and disorder: The generalized inverse participation ratio of an ensemble of two-site Anderson-Hubbard systems

description: After Anderson's prediction of disorder-induced insulating behavior, extensive work found no singularities in the density of states of localized systems. However, Johri and Bhatt recently uncovered the existence of a non-analyticity in the density of states near the band edge of non-interacting systems with bounded disorder, in an energy range outside that captured by previous work. Moreover, this feature marks the boundary of an energy range in which the localization is sharply suppressed. Given strong current interest in the effect of interactions on disordered systems, we explore here the effect of a Hubbard $U$ interaction on this behavior. We find that in ensembles of small systems a cusp in the density of states persists and continues to be associated with a sharp suppression of the localization. We explore the origins of this behavior and discuss its connection with many-body localization.

description: The first point to make is the elementary one: that not all capital cities are alike. Some owe that role solely to the fact of being the seat of government; at least one (Amsterdam) is a capital even though it is not the seat of government. Capitals in federal systems may have less well-developed governmental functions than those in centralized systems. Though most seats of government attract other national functions (commerce, finance, media, higher education), not all do so in equal degree.

description: In order to study quantum measurement theory, sequential product defined for any two quantum effects is introduced. Physically motivated conditions ask the sequential product to be continuous with respect to the strong operator topology. In this paper, we study the continuity problems of the sequential product with respect to the other important topologies, as norm topology, weak operator topology, order topology, interval topology, etc.

description: In order to learn if a common theory and practice exist and influence bibliographic instruction in academic libraries, this paper presents a view of concepts from bibliographic instruction literature.  Next, three learning theories from the field of psychology are summarized and judged according to their applicability and relevance to bibliographic instruction.  Then literature on information literacy is reviewed to find a common definition of information literacy.  Finding that the definition has shifted from describing attributes and skills to defining a concept, a personal definition of the concept of information literacy is proposed.  Then an example is offered of a research process and its accompanying skills, which are influenced by, and become the goal of, functionalist theory-based, information literacy-oriented bibliographic instruction.  Finally, topics for further research are suggested.

description: COELIOXYS (TORRIDAPIS) PASTEELS, 1977
Type species: Coelioxys torrida Smith, 1854.
Diagnosis: With C. (Liothyrapis) and the species C. (A.) madagascariensis, this Old World subgenus is the only one within Coelioxys in which the compound eyes are bare (Fig. 4). Species of C. (Torridapis) can be distinguished from C. madagascariensis by the lateral margins of axilla neither elevated nor carinate (Fig. 11) (conspicuously elevated and carinate in the latter; Fig. 6). They can be separated from those of C. (Liothyrapis) by the following list of characteristics. Axilla long, free apical portion produced beyond the posterior margin of mesoscutellum, and curved apically (Fig. 11); mesoscutellum with a dorsal median carina at least basally (Fig. 11). Female: T 6 lacking long, erect, thick hairs, with apex ending in an inconspicuous, short, spine-like process (Fig. 12); T 6 and S6 gradually tapering, greatly elongate, S6 folded, subacute apically, its lateral margins with an inconspicuous fringe composed of short brownish hairs (Fig. 12). Male: hypostomal area lacking concavity; T 6 basally lacking, or with short, flattened lateral expanded areas, never with long, acute teeth (Fig. 13); S4 medially sulcate, hairy, and S6 long, ≥1.2 9 longer than broad.
Comments: Ten species are classified in this subgenus (Ascher & Pickering, 2015), with a new one described by Rocha-Filho (2016); the four Afrotropical species were revised by Pasteels (1968) and classified as Liothyrapis, the other species come from Indomalayan or Palaearctic regions, Mauritius or Madagascar.
List of species: Coelioxys analis Friese, 1911, Coelioxys basalis Smith, 1875, Coelioxys ducalis Smith, 1854, Coelioxys fenestrata Smith, 1873, Coelioxys julia Rocha-Filho, 2016 *, Coelioxys kosemponis Strand, 1913, Coelioxys maculata Friese, 1913, Coelioxys maculoides Pasteels, 1968, C. torrida, Coelioxys torridula Pasteels, 1968, and Coelioxys weinlandi Schulz, 1904.
