description: We study the role of substorms and steady magnetospheric convection (SMC) in magnetic flux transport in the magnetosphere, using observations of field-aligned currents by the Active Magnetosphere and Planetary Electrodynamics Response Experiment. We identify two classes of substorm, with onsets above and below 65$^{\circ}$magnetic latitude, which display different nightside field-aligned current morphologies. We show that the low-latitude onsets develop a poleward-expanding auroral bulge, and identify these as substorms that manifest ionospheric convection-braking in the auroral bulge region as suggested by Grocott et al. (2009, https://doi.org/10.5194/angeo-27-591-2009). We show that the high-latitude substorms, which do not experience braking, can evolve into SMC events if the interplanetary magnetic field remains southward for a prolonged period following onset. We conclude that during periods of ongoing driving, the magnetosphere displays repeated substorm activity or SMC depending on the rate of driving and the open magnetic flux content of the magnetosphere prior to onset. We speculate that sawtooth events are an extreme case of repeated onsets and that substorms triggered by northward-turnings of the interplanetary magnetic field mark the cessation of periods of SMC. Our results provide a new explanation for the differing modes of response of the terrestrial system to solar wind-magnetosphere-ionosphere coupling by invoking friction between the ionosphere and atmosphere.

description: In this paper, we revisit the open DNS (ODNS) infrastructure and, for the first time, systematically measure and analyze transparent forwarders, DNS components that transparently relay between stub resolvers and recursive resolvers. Our key findings include four takeaways. First, transparent forwarders contribute 26% (563k) to the current ODNS infrastructure. Unfortunately, common periodic scanning campaigns such as Shadowserver do not capture transparent forwarders and thus underestimate the current threat potential of the ODNS. Second, we find an increased deployment of transparent forwarders in Asia and South America. In India alone, the ODNS consists of 80% transparent forwarders. Third, many transparent forwarders relay to a few selected public resolvers such as Google and Cloudflare, which confirms a consolidation trend of DNS stakeholders. Finally, we introduce DNSRoute++, a new traceroute approach to understand the network infrastructure connecting transparent forwarders and resolvers.

description: We prove that the entanglement entropy of any pure initial state of a bipartite bosonic quantum system grows linearly in time with respect to the dynamics induced by any unstable quadratic Hamiltonian. The growth rate does not depend on the initial state and is equal to the sum of certain Lyapunov exponents of the corresponding classical dynamics. This paper generalizes the findings of [Bianchi et al., JHEP 2018, 25 (2018)], which proves the same result in the special case of Gaussian initial states. Our proof is based on a recent generalization of the strong subadditivity of the von Neumann entropy for bosonic quantum systems [De Palma et al., arXiv:2105.05627]. This technique allows us to extend our result to generic mixed initial states, with the squashed entanglement providing the right generalization of the entanglement entropy. We discuss several applications of our results to physical systems with (weakly) interacting Hamiltonians and periodically driven quantum systems, including certain quantum field theory models.

Early History of Farm Business Management in Alberta
Creators: name: Petersen, Alf
Publisher: name: Unknown
Year: 1997
Subjects: Farm Management

description: Although farming in Alberta began more than a century ago, a formal “Farm Business Management ” approach to the industry is of more recent origin. While there were a few beginnings prior to World War II, professionalization of the field has developed mainly over the past generation of farm operators. While agricultural vocational schools were established early in this century, the emphasis was on farming husbandry practices, although a few instructors did introduce farm accounting courses on an elementary and “adhoc” basis. Accounting and business analysis were not as crucial then. Most farm inputs were generated within the farm itself Cash flow and insolvency risks were small in comparison to the present day farm business. The roots of professional Farm Business Management (FBM) in Alberta were inadvertently initiated in the late 1930's by agricultural economist Dr. Howard Patterson from Ontario. He was commissioned to undertake a general study of the dairy industry in Alberta. A problem with unreliable year-roundfluid milk supply was developing, but the precipitating crisis was an outbreak of undulant fever caused by farm infected milk. As a result, in 1939 the regulation of fluid milk was put under the Alberta Public Utility Board Delivery quotas were set, and farm milk prices were to be based on producers' “cost of production. ” With several hundred fluid milk producers, each with their own unique costs, the burning question was: whose costs should be used for establishing the year's prices, the lowest, the lowest 25%, the average of all, or some other criterion? Economic efficiency measures became crucial. This was an important step in the introduction of the farm business analysis concept in Alberta. Ben J. McBain B.Sc. (Agric) was hired by the Alberta government, but stationed at the University of Alberta, along with the small contingent of economists from the University and Agriculture Canada economists. McBain's task was to establish farm record keeping systems on representative samples of Alberta fluid milk farmers. These were collected annually, and analyzedfor fluid milk production costs as well as important farm management efficiency measures. This project became known as the Alberta Dairy Cost Studies. Dr. Patterson returned to Ontario, where he established and directed a Farm Economics Branch within the Ontario Department of Agriculture for the remainder of his working life. Farm Business Management was an important component of the Branch, and the continuing information exchanges with the Alberta Farm Cost Studies were beneficial. Physical proximity to the federal Agricultural Economics Division staff housed at the University of Alberta was also of benefit, although their work was not directly in the Farm Business Management field Its long time Head in Alberta was Dr. Clarence Spence.

description: We report an investigation of X-ray induced desorption of neutrals, cations and anions from CO ice. The desorption of neutral CO, by far the most abundant, is quantified and discussed within the context of its application to astrochemistry. The desorption of many different cations, including large cations up to the mass limit of the spectrometer, are observed. In contrast, the only desorbing anions detected are O$^-$ and C$^-$. The desorption mechanisms of all these species are discussed with the aid of their photodesorption spectrum. The evolution of the X-ray absorption spectrum shows significant chemical modifications of the ice upon irradiation, which along with the desorption of large cations gives a new insight into X-ray induced photochemistry in CO ice.

title: A cultural policy of the multitude in the time of climate change;
with an understanding that the multitude has no policy
Creators: name: Herbst, Marc Allen
Publisher: name: Goldsmiths, University of London
Year: 2019

description: The changing climate will globally force drastic changes in how people live. Globally,
governance supports its own interests while the multitude everywhere bear the burdens
that rest between such interests and climate vacillation. That the multitude is composed of
those who everywhere precede and exceed governance, who are necessary to its
constitution but don’t necessarily need it, suggests that the multitude tautologically selfgoverns
somehow through concepts. These concepts are things that have managerial and
governmental faces in whose creation the multitude participates but may or may not like.
This cultural study understands that by relating to each other and the earth through
general capacities of sociality, humanity solidifies cultural ways of being human, and that
these cultural ways are governing creations. This study thinks through the ways that
culture, beside or beyond formal governance, can best support multitudinous human
relations towards general livability in the time of climate change. The Barcelona-based
Plataforma De Afectados Por La Hipoteca (PAH), an autonomous movement fighting for
housing rights, serves as a means to model how social relations reorganize governance in
the multitude’s interest. Virno’s refinement of Marx’s theory of general intellect, and the
even more general sociality suggested by Spinoza, describe the immediate social
capacities demonstrated by the PAH. This study also works through the UK-based
climate poetry journal, the Dark Mountain Project, to grasp issues attendant to climate
and governance and cultural work. Culture is discussed anthropologically and art
historically – critically discussing Hegel’s conceptions of universal qualities in relation to
feminist, post-colonial and autonomist Marxist theories, thereby suggesting ways for
cultural workers to think through cultural forms and ways that support multitudinous
being in variable relation to governance and the changing climate.

The rise and fall of branching: a slowing down mechanism in relaxing wormlike micellar networks

subject: FOS: Physical sciences

description: A mean-field kinetic model suggests that the relaxation dynamics of wormlike micellar networks is a long and complex process due to the problem of reducing the number of free end-caps (or dangling ends) while also reaching an equilibrium level of branching after an earlier overgrowth. The model is validated against mesoscopic molecular dynamics simulations and is based on kinetic equations accounting for scission and synthesis processes of blobs of surfactants. A long relaxation time scale is reached both with thermal quenches and small perturbations of the system. The scaling of this relaxation time is exponential with the free energy of an end cap and with the branching free energy. We argue that the subtle end-recombination dynamics might yield effects that are difficult to detect in rheology experiments, with possible underestimates of the typical time scales of viscoelastic fluids.

Con el viento solano de Ignacio Aldecoa y la novelistica española de postguerra
Creators: name: Manchon, Enrique
Publisher: name: University of British Columbia
Year: 2010

description: Ignacio Aldecoa (1925-1969) is an important figure of the Spanish novelistic revival that has evolved in the decades after the Spanish Civil Far (1936-1939). The present study examines his second novel; Con el vicnto solano (With the East Find), published in 1956, in the light of the literary and historical background of the period, with the purpose of revealing the realities and preoccupations, both literary and social, that it reflects, and of determining its intrinsic value. The study is divided into three chapters. In the first chapter we provide a recapitulation of the Spanish, post-war narrative through the presentation of three established, distinct and complementary critical approaches (the chronological, the thematic and the formal) and through the subsequent explanation of pertinent taxonomy and nomenclature (divisions such as first post-war generation, second post-war generation, new novel, and terminology such as realism, new-realism, neo-realism, objectivism, objective realism, behaviouralisM, nouveau roman and others are discussed). Aldecoa is identified as a member of the generation of novelists of the 1950's recognized as having brought to Spanish literature, from external influences, a needed breath of technical awareness and for having directed the focus of attention to the common everyday aspects of the national social crisis. In the second chapter we explore the themes of the novel in question from the perspective of the three main thematic directions of the period: the "existential" of the forties, the "social" of the fifties, and the "structural" of the sixties. Con elviento solano, in fact, synthesizes these three directions, and by incorporating the last one, it assumes the role of a precursor. The last chapter constitutes an investigation of the formal aspects of the novel. We look at two elements of form (structure, and narrative perspective), to find that this novel shows important advances in Spanish narrative technique that are symptomatic of a new and general visualization of the world. The structure is analysed through the concept of "discontinuity", which in our novel seems to be closely linked to the cinematographic montage technique. Stylistically, AideCoa moves from instances of objective technique to moments of poetic subjectivity, on occasions presenting a selective balance of the two, through which his narrative achieves a characteristic overall sense of objectivity. Furthermore, we also perceive in the narration the sometimes unavoidable involvement of external elements. The presence of objects ("objectalism") has, at times, a fatalistic effect. The ever—present east wind acquires a mythic and deterministic value. As an image-motif, the wind represents the author's fatalistic philosophy and corresponds with the novel's structural discontinuity, thus constituting the integral expression of the work.
Wormhole geometries in $f(Q)$ gravity and the energy conditions

description: Following the recent theory of $f(Q)$ gravity, we continue to investigate the possible existence of wormhole geometries, where $Q$ is the non-metricity scalar. Recently, the non-metricity scalar and the corresponding field equations have been studied for some spherically symmetric configurations in [ Phys. Lett. B 821, 136612 (2021) and Phys. Rev. D 103, 124001 (2021) ]. One can note that field equations are different in these two studies. Following [Phys. Rev. D 103, 124001 (2021)], we systematically study the field equations for wormhole solutions and found the violation of null energy conditions in the throat neighborhood. More specifically, considering specific choices for the $f(Q)$ form and for constant redshift with different shape functions, we present a class of solutions for static and spherically symmetric wormholes. Our survey indicates that wormhole solutions could not exist for specific form function $f(Q)= Q+ αQ^2$. To summarize, exact wormhole models can be constructed with violation of the null energy condition throughout the spacetime while being $ρ\geq 0$ and vice versa.

Material: Two males, NGK-Nimba 0060, NGK-Nimba 0061, and two females, NGK-Nimba 0062, NGK-Nimba 0063 (Fig. 14A).
Comments: Five P. retropunctata were recorded on a high plateau with predominantly grassy mountain pastures and herbaceous vegetation (07°35.453’N, 008°24.957’W; 843 m asl). The SULs of males varied from 28.0– 30.5 mm (N = 3), while two females measured 29.0 and 37.5 mm. Whereas four frogs were rust-colored, a female had a deep brown dorsum. In contrast to Rödel (2000) and Channing and Rödel (2019), who describe a white venter, our specimens had a yellow venter. The species was described previously from Mounts Nimba (Angel 1949). Further records became known only from a few montane localities in southeastern Guinea (summarized in Rödel et al. 2004), the Loma Mountains in Sierra Leone (Lamotte 1971), northern Guinea (Hillers et al. 2006), and southeastern Senegal (Monasterio et al. 2016). This is the first country record for P. retropunctata in Ivory Coast.

Comments: Two females of the Ptychadena stenocephala -complex (Rödel and Channing 2019) have been found at the edge of a roadside puddle near a heavily degraded forest in the Yéalé village (07°31.928’N, 008°25.401’W; 425 m asl). While they superficially resemble P. mascareniensis, e.g., by the ridges and a similar vertebral band (see e.g., Rödel and Glos 2019), they differ from the latter species by reduced webbing, and much more slender body shape (Channing and Rödel 2019). The exact taxonomic status of these frogs requires further research.

We introduce the Frobenius category of $ω$-Cohen-Macaulay objects, and under some reasonable conditions, we show that the stable category of $ω$-Cohen-Macaulay objects is triangle-equivalent to the relative singularity category. As applications, we relate the stable category of (unnecessarily finitely-generated) Gorenstein-projective modules with singularity categories of rings. We prove that for a Gorenstein ring, the stable category of Gorenstein-projective modules is compactly generated and its compact objects coincide with finitely-generated Gorenstein-projective modules up to direct summands.

Benjamin J. McBain: A Pioneer In Alberta Farm Business Management
Creators: name: Petersen, Alf
Publisher: name: Unknown
Year: 1997
Subjects: Farm Management

description: Farm Business Management as a professional practice is relatively new in the province of Alberta. It was not until 1962 that the University of Alberta established the Department of Rural Economy within its Faculty of Agriculture. Consequently, only the recent generation of Alberta professional Farm Business Management Specialists have had the opportunity to gain that status within their own province. Support for establishment of such a department within the University came not only from farm organizations, but also professionals working with farm managers within the province, on business management problems. One of these was Benjamin J. McBain B.Sc.(Agric). He was a participant in the establishment of Fluid Milk Price Control within the province, and spent most of his professional career as Head of Dairy Cost Studies, located at the University of Alberta, but employed by the Province. He soon discovered that cost accounting was an important key to successful farm management decisions, and the program was expanded to other types of farming, with increased staff. It became one of the important catalysts in the push for a Farm Management Extension component within the Alberta Department of Agriculture, and the establishment of the Department of Rural Economy at the University of Alberta. Both of these entities came into being in the early 1960’s, and have become institutions which are of strategic importance to the farming industry andfarm business management professionals. Ben McBain has willed a substantial portion of his estate to the University of Alberta for research in farm business management topics which are potentially useful to farm managers and professional farm business management advisors. It provides, into perpetuity, an annual scholarship of $12,000 which is available to the successful candidate for a two year period of post graduate training. The scholarship is named “The B. J. McBain Scholarship in Farm Business Management. ”

description: Quenching alkaline bismuth titanates from sintering temperatures results in increased lattice distortion and consequently higher depolarization temperature. This work investigates the influence of quenching on the ergodicity of relaxor Na₁/₂Bi₁/₂TiO₃‐BaTiO₃‐K₀.₅Na₀.₅NbO₃. A distinct departure from ergodicity is evidenced from the increase in remanent polarization and the absence of frequency dispersion in the permittivity response of poled samples. Further, the samples exhibit enhanced negative strain upon application of electric field, indicating proclivity towards correlated polar nanoregions, corroborated by the enhanced tetragonal distortion. As a result, ergodic relaxor Na₁/₂Bi₁/₂TiO₃‐6BaTiO₃‐3K₀.₅Na₀.₅NbO₃ exhibits a depolarization temperature of 85°C with a 60% increase in remanent polarization and approximately a threefold increase in remanent strain upon quenching. Quenching‐induced changes in the local environment of Na⁺ and Bi³⁺ cations hinder the development of ergodicity promoted by the A‐site disorder. These results provide new insight into tailoring ergodicity of relaxor ferroelectrics.

description: Ptychadena submascareniensis (Guibé and Lamotte, 1953)
Small Grass Frog
Material: Three females, NGK-Nimba 0044, NGK-Nimba 0046, NGK-Nimba 0047 (Fig. 14C), and two males, NGK-Nimba 0048, NGK-Nimba 0049 (Fig. 14D).
Comments: We found a large population of P. submascareniensis in predominantly grassy mountain pastures with herbaceous vegetation (07°35.453’N, 008°24.957’W; 843 m asl). There, the species occurred in vast numbers (> 1,500 individuals in an area of approximately 50 ha) during the rainy season. Calling males were observed during the day with peaks between 0830–1030 h GMT and 1830–2000 h GMT. The weather conditions during these observations were characterized by low visibilities due to mist and windy weather. We recorded two migrating individuals in montane grassland in sympatry with A. crusculum and N. occidentalis (07°35.555’N, 008°25.788’W; 1,235 m asl). These rarely documented frogs (compare Guibé and Lamotte 1953, 1958a; Rödel and Bangoura 2004) have a compact body with a moderately pointed snout. Adult females measured 29.5–32.0 mm (N = 8), while males ranged from 24.0– 27.5 mm (N = 18). According to Channing and Rödel (2019), Mount Nimba is the only known Ivorian site to host P. submascareniensis.

description: The Additional Representative Images for Legacy (ARI-L) project is a European Development project for ALMA Upgrade approved by the Joint ALMA Observatory (JAO) and the European Southern Observatory (ESO), started in June 2019. It aims to increase the legacy value of the ALMA Science Archive (ASA) by bringing the reduction level of ALMA data from Cycles 2-4 close to that of data from more recent Cycles processed for imaging with the ALMA Pipeline. As of mid-2021 more than 150000 images have been returned to the ASA for public use. At its completion in 2022, the project will have provided enhanced products for at least 70% of the observational data from Cycles 2-4 processable with the ALMA Pipeline. In this paper we present the project rationale, its implementation, and the new opportunities offered to ASA users by the ARI-L products. The ARI-L cubes and images complement the much limited number of archival image products generated during the data quality assurance stages (QA2), which cover only a small fraction of the available data for those Cycles. ARI-L imaging products are highly relevant for many science cases and significantly enhance the possibilities for exploiting archival data. Indeed, ARI-L products facilitate archive access and data usage for science purposes even for non-expert data miners, provide a homogeneous view of all data for better dataset comparisons and download selections, make the archive more accessible to visualization and analysis tools, and enable the generation of preview images and plots similar to those possible for subsequent Cycles.

description: Amnirana sp. ‘albolabris-West’
West African White-lipped Frog
Material: Female, NGK-Nimba 0101 (Fig. 14F).
Comments: Amnirana sp. ‘albolabris-West’ is a forest-dwelling frog occurring in the Upper Guinean zone, formerly regarded as being conspecific with the real A. albolabris from Central African forests (Jongsma et al. 2018). While its description is being prepared, the occurrence of this species has been even more recently confirmed for Burkina Faso (Ayoro et al. 2020). This taxon was recorded in the Yéalé village, where a chorus was heard at night in a densely vegetated swampy area. One to two males initiated calling and many other males then joined the chorus. A similar behavior was also observed in A. fonensis (Kouamé et al., unpub. data). In the Yéalé village, frogs belonging to A. sp. ‘albolabris-West’ were also found in large numbers (N> 50) in a cocoa and coffee plantation near a large pond. Females had a less spiny back than males (Fig. 14G).

description: We report results of fast neutron response in plastic scintillator (PS) bars from deuterium-deuterium (D-D) and deuterium-tritium (D-T) reactions using Purnima Neutron Generator Facility, BARC, Mumbai. These measurements are useful in context of Indian Scintillator Matrix for Reactor Anti-Neutrino (ISMRAN) detection, an array of 10x10 PS bars, used to measure reactor anti-neutrinos through inverse beta decay (IBD) signal. ISMRAN detector, an above-ground experiment close to the reactor core (~13m), deals with an active fast neutron background inside the reactor hall. A good understanding of fast neutron response in PS bars is an essential pre-requisite for suppression and discrimination of fast neutron background from IBD events. A monoenergetic neutron beam from the fusion reaction of D-D at 2.45 MeV and D-T at 14.1 MeV are used to characterize the energy response in these bars. The neutron energy response function has been simulated using the GEANT4 package and are compared with the measured data. A reasonable agreement of deposited energies by fast neutrons in PS bars between data and simulation are obtained for these reactions. The ratio of energy deposition in adjacent bars is used to discriminate between prompt IBD, fast neutron and neutron capture cascade gamma events.

Chiromantis rufescens

description: Chiromantis rufescens (Günther, 1869)
Western Foam-nest Frog
Material: Male, NGK-Nimba 0102 (Fig. 14H).
Comments: Chiromantis rufescens is a complex of treefrog species (Leaché et al. 2019), occurring in rainforest and the transition zone between forest and savannah, from West and Central Africa to the southernmost record in Angola (Lamotte 1967; Schiøtz 1967; Channing and Rödel 2019; Rödel and Glos 2019; Ernst et al. 2020). They are the only West African species depositing foam nests above stagnant waters (Coe 1967, 1974; Schiøtz 1967; Monayong Ako’o 1978; Rödel et al. 2002). During the entire survey in Mounts Nimba, only one specimen was found on a dark night in a plantation from the Yéalé village dominated by cocoa and coffee trees (Fig. 14H). This specimen measured 45.0 mm in SUL.

description: We investigate the nature of trions, pairing and quantum phase transitions in one-dimensional strongly attractive three-component ultracold fermions in external fields. Exact results for the groundstate energy, critical fields, magnetization and phase diagrams are obtained analytically from the Bethe ansatz solutions. Driven by Zeeman splitting, the system shows exotic phases of trions, bound pairs, a normal Fermi liquid and four mixtures of these states. Particularly, a smooth phase transition from a trionic phase into a pairing phase occurs as the highest hyperfine level separates from the two lower energy levels. In contrast, there is a smooth phase transition from the trionic phase into a normal Fermi liquid as the lowest level separates from the two higher levels.

description: We present an analysis of high resolution VLT-FLAMES spectra of 61 B-type stars with relatively narrow-lined spectra located in 4 fields centered on the Milky Way clusters; NGC3293 & NGC4755 and the Large and Small Magellanic cloud clusters; NGC2004 and NGC330. For each object a quantitative analysis was carried out using the non-LTE model atmosphere code TLUSTY; resulting in the determination of their atmospheric parameters and photospheric abundances of the dominant metal species (C, N, O, Mg, Si, Fe). The results are discussed in relation to our earlier work on 3 younger clusters in these galaxies; NGC6611, N11 and NGC346 paying particular attention to the nitrogen abundances which are an important probe of the role of rotation in the evolution of stars. This work along with that of the younger clusters provides a consistent dataset of abundances and atmospheric parameters for over 100 B-type stars in the three galaxies. We provide effective temperature scales for B-type dwarfs in all three galaxies and for giants and supergiants in the SMC and LMC. In each galaxy a dependence on luminosity is found between the three classes with the unevolved dwarf objects having significantly higher effective temperatures. A metallicity dependence is present between the SMC and Galactic dwarf objects, and whilst the LMC stars are only slightly cooler than the SMC stars, they are significantly hotter than their Galactic counterparts.
