description: A superconducting qubit was driven in an ultrastrong fashion by an oscillatory microwave field, which was created by coupling via the nonlinear Josephson energy. The observed Stark shifts of the `atomic' levels are so pronounced that corrections even beyond the lowest-order Bloch-Siegert shift are needed to properly explain the measurements. The quasienergies of the dressed two-level system were probed by resonant absorption via a cavity, and the results are in agreement with a calculation based on the Floquet approach.

description: Context. Emission and absorption line profiles which are formed in the interaction of pre-main sequence (PMS) stars and their circumstellar environment are found to be variable at various timescales. Aims. We investigate the patterns and timescales of temporal line profile variability in order to explore the dynamical circumstellar environment of the PMS Herbig Ae star V351 Ori. Methods.We obtained 45 high-resolution (R~28,000) spectra of V351 Ori at timescales of hours, days, and months.We analysed the Hαline profiles and also examined the Hβ, NaD1 and NaD2 line profiles to explore the nature of the spectroscopic variability. Results. The Hαline profiles showed strong variations over all timescales. The shape of the profiles changed over timescales of a day. Single as well as simultaneous event(s) of blue-shifted and red-shifted transient absorption components (TACs), i.e. signatures of outflow and infall, were also observed in the Hαline profiles. The shortest period of variation in the TACs was < 1 hour. All transient absorption events were found to decelerate with a rate of a few to fractions of m s-2. The depth and width of the TACs were also changing with time. The presence of elongated red-shifted components at some epochs supports the episodic nature of accretion. Conclusions. Variable emission and absorption components detected in Hαline profiles show the dynamic nature of interaction between V351 Ori and its circumstellar environment. The Hαnon-photospheric profiles of the star most probably originate in the disk wind. Episodic accretion of gaseous material at a slow rate and outflow of clumpy gaseous material are still occurring in V351 Ori at an age of ~6.5 Myr. Dynamic magnetospheric accretion and disk wind emerge as the most satisfactory model for interpreting the observed line profile variations of V351 Ori.

Publisher: name: University of British Columbia

description: This study focused on investigating Kindergarten to Grade12 (K-12) teachers’ perspectives about the effects of students’ cultural diversity on their science and mathematics teaching and their perspectives and understandings of culturally responsive teaching. Largely informed by the principles of qualitative case study approach, this investigation employed phenomenographic methods including individual teacher interviews and informal observations of select science and mathematics classrooms for data collection and analysis. Participants included ten teachers from Vancouver, a major urban city in Western Canada. A synthesized theoretical framework of (trans-multi)culturally responsive education comprising of critical and transformational multicultural education perspectives and complementing notions of culturally responsive teaching served as a guiding lens to analyze and interpret the data. Two research questions were addressed: 1) What are K-12 teachers’ perspectives about the effect of cultural diversity on their science and mathematics teaching? 2) What are the teachers’ understandings of and perspectives on culturally responsive teaching as a viable strategy for teaching science and mathematics in their cultural diversity-rich classrooms? Key findings illustrate that: 1) teachers described students’ cultural diversity as a mosaic as well as a strength and a challenge; 2) teachers recognized the level of English language competency as one of the key systemic factors compounding the challenges associated with students’ cultural diversity; 3) lack of culturally relevant resources, support and training serve as an impediment to teachers’ successful integration of Indigenous knowledges in their science and mathematics classrooms; 4) teachers’ perspectives of science and mathematics, cultural diversity, and Canadian culture were full of contradictions; and 5) teachers’ understandings of culturally responsive teaching and its manifestation in their classrooms were diverse and full of conundrums. The findings have implications for future research on how teachers’ perspectives of students’ cultural diversity influence their expectations of culturally diverse students’ engagement and achievements, and their assessment practices in science and mathematics classrooms. The findings also demand further research focusing on whether teaching the content of science and mathematics limits teachers’ pedagogical responsiveness where they may merely “talk the walk” of multicultural education without realizing the actual potential of students’ and communal funds of knowledges in their diversity-rich classrooms.

description: En una de tantas visitas a la ciudad de Matanzas con motivo de valorar el trabajo sobre el legado africano en la cultura cubana, como parte del proyecto de la UNESCO La Ruta del Esclavo, primero como coordinador del Comité Cubano desde 1994 y entre 2011-2015 como Miembro del Comité Científico Internacional, conocí el arduo desempeño realizado en el barrio matancero de Pueblo Nuevo en lo que después se ha convertido en El Callejón de las Tradiciones. Un espacio inicialmente ruinoso que sus pobladores, con la guía y el entusiasmo del hoy Máster Yoelkis Torres Tápanes, fueron edificando y han sabido encaminar hacia la sostenibilidad, una tarea muy ansiada por otros proyectos socioculturales.
 Más tarde, durante mi participación como profesor en la Maestría en Estudios históricos y de antropología sociocultural cubana en la Universidad de Cienfuegos, que fue cursada exitosamente por Yoelkis, supe en detalles todo cuanto han trabajado para sembrar y recoger, paso a paso, los frutos para continuar adelante.

An initially dilapidated space that its residents, with the guidance and enthusiasm of today’s Master Yoelkis Torres Tápanes, have been building and have been able to move towards sustainability, a task much sought after by other socio-cultural projects.
 Later, during my participation as a professor in the Master’s program in historical studies and socio-cultural anthropology of Cuba at the University of Cienfuegos, which was successfully completed by Yoelkis, I learned in detail all that they have worked to sow and harvest, step by step, the fruits to continue forward.

Sparsity-Cognizant Total Least-Squares for Perturbed Compressive Sampling

description: Solving linear regression problems based on the total least-squares (TLS) criterion has well-documented merits in various applications, where perturbations appear both in the data vector as well as in the regression matrix. However, existing TLS approaches do not account for sparsity possibly present in the unknown vector of regression coefficients. On the other hand, sparsity is the key attribute exploited by modern compressive sampling and variable selection approaches to linear regression, which include noise in the data, but do not account for perturbations in the regression matrix. The present paper fills this gap by formulating and solving TLS optimization problems under sparsity constraints. Near-optimum and reduced-complexity suboptimum sparse (S-) TLS algorithms are developed to address the perturbed compressive sampling (and the related dictionary learning) challenge, when there is a mismatch between the true and adopted bases over which the unknown vector is sparse. The novel S-TLS schemes also allow for perturbations in the regression matrix of the least-absolute selection and shrinkage selection operator (Lasso), and endow TLS approaches with ability to cope with sparse, under-determined "errors-in-variables" models. Interesting generalizations can further exploit prior knowledge on the perturbations to obtain novel weighted and structured S-TLS solvers. Analysis and simulations demonstrate the practical impact of S-TLS in calibrating the mismatch effects of contemporary grid-based approaches to cognitive radio sensing, and robust direction-of-arrival estimation using antenna arrays.

Testing composite hypotheses, Hermite polynomials and optimal estimation of a nonsmooth functional

description: A general lower bound is developed for the minimax risk when estimating an arbitrary functional. The bound is based on testing two composite hypotheses and is shown to be effective in estimating the nonsmooth functional ${\frac{1}{n}}\sum|θ_i|$ from an observation $Y\sim N(θ,I_n)$. This problem exhibits some features that are significantly different from those that occur in estimating conventional smooth functionals. This is a setting where standard techniques fail to yield sharp results. A sharp minimax lower bound is established by applying the general lower bound technique based on testing two composite hypotheses. A key step is the construction of two special priors and bounding the chi-square distance between two normal mixtures. An estimator is constructed using approximation theory and Hermite polynomials and is shown to be asymptotically sharp minimax when the means are bounded by a given value $M$. It is shown that the minimax risk equals $β_*^2M^2({\frac{\log\log n}{\log n}})^2$ asymptotically, where $β_*$ is the Bernstein constant. The general techniques and results developed in the present paper can also be used to solve other related problems.

description: The CCD photometric observations of the eclipsing binary PS Persei (PS Per) were obtained on two consecutive days in 2009. The 2003 version Wilson-Devinney code was used to analyze the first complete light curves in $V$ and $R$ bands. It is found that PS Per is a short-period Algol-type binary with the less massive component accurately filling its inner critical Roche lobe. The mass ratio of $q=0.518$ and the orbital inclination of $i=89.^{\circ}86$ are obtained. On the other hand, based on all available times of primary light minimum including two new ones, the orbital period has been improved.

A multi-omics approach to microbial nitrogen and sulfur cycling in the oxygen starved ocean
Creators: name: Hawley, Alyse Kathleen
Publisher: name: University of British Columbia
Year: 2018

description: Microbial communities mediate biogeochemical processes of Carbon (C), Nitrogen (N) and Sulfur (S) cycling in the ocean on global scales. Oxygen (O₂) availability is a key driver in these processes and shapes microbial community structure and metabolisms. As O₂ decreases, microbes utilize alternative terminal electron acceptors, nitrate (NO₃–), nitrite, sulfate and carbon dioxide, depleting biologically available nitrogen and producing greenhouse gases nitrous oxide (N₂O) and methane (CH₄). Marine oxygen minimum zones (OMZs) are areas of O₂-depletion (O₂ < 20µM) in sub-surface waters due to the respiration of organic matter from the surface. In areas of acute O₂-depletion or where OMZs contact underlying sediments, hydrogen sulfide (H₂S) and CH₄ accumulate within OMZ waters, drastically altering microbial community structure and metabolism. In this thesis, I explore microbial cycles along defined gradients of O₂, NO₃- and H₂S in Saanich Inlet, a seasonally anoxic fjord on the coast of British Columbia Canada. I develop a time-resolved multi-omic dataset consisting of small subunit ribosomal RNA amplicon sequences, single cell amplified genomes (SAGs), metagenomes, -transcriptomes and -proteomes, coupled with geochemical measurements, enabling robust microbial metabolic reconstruction at the individual, population and community levels of organization. Using metaproteomics, I construct a conceptual model of metabolic interactions involving N and S cycling, and carbon fixation, forming the basis for a collaborative effort to build a gene-centric numerical model, identifying an unrecognized niche for N₂O reduction. Using single cell amplified genomes (SAGs) from Saanich Inlet, I identify genes for N₂O reduction, nosZ, within the dark matter phylum Marinimicrobia clade SHBH1141, filling the proposed niche of non-denitrifying N₂O-reducers. Using globally sourced Marinimicrobia SAGs, I further analyze energy metabolism and biogeography of several Marinimicrobia clades, revealing roles in C, N and S cycling along eco-thermodynamic gradients throughout the ocean. Finally, I chart the global abundance and distribution of nosZ genes and transcripts within the ocean, identifying previously unappreciated potential sinks for N₂O. As OMZs continue to expand and intensify due to climate change, defining metabolic processes and interactions along gradients of O₂-depletion becomes increasingly important. This thesis provides foundational knowledge related to the microbial communities driving coupled biogeochemical cycling in OMZs.

Entanglement, intractability and no-signaling

Publisher: name: arXiv
Year: 2010
Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: We consider the problem of deriving the no-signaling condition from the assumption that, as seen from a complexity theoretic perspective, the universe is not an exponential place. A fact that disallows such a derivation is the existence of {\em polynomial superluminal} gates, hypothetical primitive operations that enable superluminal signaling but not the efficient solution of intractable problems. It therefore follows, if this assumption is a basic principle of physics, either that it must be supplemented with additional assumptions to prohibit such gates, or, improbably, that no-signaling is not a universal condition. Yet, a gate of this kind is possibly implicit, though not recognized as such, in a decade-old quantum optical experiment involving position-momentum entangled photons. Here we describe a feasible modified version of the experiment that appears to explicitly demonstrate the action of this gate. Some obvious counter-claims are shown to be invalid. We believe that the unexpected possibility of polynomial superluminal operations arises because some practically measured quantum optical quantities are not describable as standard quantum mechanical observables.

The experimental NMOR signals as a function of rf field frequency for various rf field powers are compared to a theoretical model based on the density-matrix formalism. The comparison between experiment and theory enables understanding of the ground-state atomic spin polarization dynamics, illustrated using plots of the probability distribution of the atomic angular momentum.

We prove that the perturbed system blows up with total probability and establish its order of magnitude and asymptotic distribution. For initial data in the domain of explosion we prove that the explosion time converges to the deterministic one while for initial data in the domain of attraction of the stable equilibrium we show that the system exhibits metastable behavior.

description: We show that Lorentz symmetry is generally absent for noncommutative (abelian) gauge theories and obtain a compact formula for the divergence of the Noether currents that allows a throughout study of this instance of symmetry violation. We use that formula to explain why the results of "Noncommutative gauge theories and Lorentz symmetry", Phys. Rev. D {\bf 70}, 125004 (2004) by R.Banerjee, B.Chakraborty and K.Kumar, interpreted there as new criteria for Lorentz {\it invariance}, are in fact just a particular case of the general expression for Lorentz {\it violation} obtained here. Finally, it is suggested that the divergence-formula should hold in a vast class of cases, such as, for instance, the Standard Model Extension.

description: The article’s objective is to outline the function of wells in settlement areas of Central European communities in Late Antiquity. The intended use as water collectors is not always as obvious and unambiguous as it might seem. In the past, these facilities fulfilled many functions, quite frequently ones of special importance. The character of the finds obtained from the wells in Kwiatków and other water collectors of the Przeworsk Culture, their constructions and their placement in the area of the settlement indicate that the intended use of these structures varied. Palaeoecological analyses facilitate the further detailing of their functions. In Kwiatków, first and foremost they were sources of drinking water for both private and public use and animals as well. They were also facilities related to the pretreatment of flax. Probably food was stored in some of them, too. They could also be used to soak antler before processing it. Certain categories of finds also suggest their cult function.

description: The term digital inclusion has been used to articulate the policy, research and practical efforts to look beyond issues of access to computers and the Internet and toward a more robust understanding of the skills, content and services needed to support individuals, families and communities in their abilities to truly adopt computers and the internet. Presently, the deep penetration of digital technologies into the fabric of society have boosted growth, expand opportunities and improved service delivery, resulting in a high level of connectivity between people, businesses and governments. This present review examines the theoretical and conceptual foundations of digital inclusion in light of developmental realities in Nigeria. Specifically, this review considers the framework for inquiry into the technological divide, the new psychological model of e-adoption within the context of the digital divide, the three-step path to engaging with the internet, and a model of digital literacy. The review also considers key conceptual definitions of digital inclusion, the stages of digital inclusion, and approaches to measuring digital inclusion. The implication of digital inclusion for mathematics education students and the Nigerian economy was also discussed.

Story of one Woman – New Bioarchaeological Data on the Interpretation of a Roman Iron Age Grave in a Log Coffin from Bagicz (woj. zachodniopomorskie / PL)

description: In 1899 a log coffin was discovered on the Baltic seashore in Bagicz. Human remains were radiocarbon dated to 160 cal BC - 50 cal AD, contrary to artefacts that date this burial to phase B2-B2/C1 (AD 110/120-160) of the Roman Iron Age. In this case a reservoir effect has to be taken into consideration. However, δ13CVPDB values do not support the marine fish consumption. The values are low and typical of a C3 based diet. High δ15NAIR values can be interpreted as either a high animal protein intake or stress. Significant consumption of freshwater fish can result in elevated δ15N values with moderate δ13C values and in aging the radiocarbon age of the individuals. The results also raise questions about the absence of millet and marine resources in the diet. Sometimes the difference in the diet can be explained by the non-local origin of the individuals. The provenance was studied by the analysis of the oxygen and strontium isotope ratio. The measured values most likely indicate a local origin. Another issue here would be the social position of the deceased. The careful interpretation of the cliff grave against the cultural background led us to assume that it had not in fact been a single grave. At this point, both grave goods and bioarchaeological results showed that we were dealing with a typical female member of the Wielbark Culture, rather than a »princess«.

description: We present a new method to describe the kinetics of driven lattice gases with particle-particle interactions beyond hard-core exclusions. The method is based on the time-dependent density functional theory for lattice systems and allows one to set up closed evolution equations for mean site occupation numbers in a systematic manner. Application of the method to a totally asymmetric site exclusion process with nearest-neighbor interactions yields predictions for the current-density relation in the bulk, the phase diagram of non-equilibrium steady states and the time evolution of density profiles that are in good agreement with results from kinetic Monte Carlo simulations.

Mary on the Eve of the Second Vatican Council

Publisher: name: University of Notre Dame
Year: 2023

description: \u000aThe Blessed Virgin Mary is uniquely associated with Catholicism, and the century preceding the Second Vatican Council was arguably the most fertile era for Catholic Marian studies. In 1964, Pope John Paul VI published the Dogmatic Constitution on the Church, or _Lumen Gentium_ (LG), the eighth chapter of which presents the most comprehensive magisterial teaching on the Blessed Virgin Mary. As part of its Marian Initiative, the Institute for Church Life at the University of Notre Dame invited scholars to a conference held at Notre Dame in October 2013 to reflect the rich Marian legacy on the eve of the Second Vatican Council.\u000a \u000aThe essays unanimously stress that the Blessed Virgin Mary is not merely a peripheral figure in Christian faith and in the panorama of theology. More than fifty years after _Lumen Gentium_, students of theology as well as Marian devotees take their bearings from this document in order to promote the person of Mary and the study of Mariology, as well as grow in authentic Marian piety. This book will have great appeal to students and scholars of Catholic theology and history, particularly those interested in Mariology.\u000a \u000aContributors: Ann W.

description: Im Kastellstandort Călugăreni / Mikháza am dakischen Ostlimes wurde bei Notgrabungen im vicus eine Spardose geborgen, die sich weitgehend zusammensetzen ließ. Ungewöhnlich ist, dass die Spardose – obwohl sie äußerlich der üblichen kugeligen Form entspricht – in zwei Kammern geteilt war und über zwei Einwurfschlitze unterschiedlicher Größe verfügte. Offenbar sollten in den kleineren, zentral eingeschnittenen Schlitz die kleineren Silbermünzen mit einem Durchmesser von etwa 20 mm – Antoniniane und Denare – eingeworfen werden und in den großen Schlitz die größeren Bronzemünzen mit einem Durchmesser von 25-35 mm – Sesterze, Asse und Dupondien. Ob die Spardose jemals in Gebrauch war, ist unklar. Entweder sie wurde auf einer Seite aufgeschlagen und geleert oder es war ein Fehlbrand, der nie in Gebrauch war: Da es sich bei den Keramikfunden im Umfeld möglichweise um Töpfereischutt handelt, könnte das Stück auch ein Fehlbrand sein.

Kettenverteiler und zwei Perlrandschalen vom Üetliberg (Kt. Zürich / CH): Überreste eines hallstattzeitlichen Wagengrabs?
Creators: name: Kienholz, Anna
Publisher: name: Archäologisches Korrespondenzblatt

description: Im Jahr 2014 wurde auf dem Üetliberg bei Prospektionsarbeiten unweit des »Hauptwalls« ein hallstattzeitlicher Fundkomplex bestehend aus zwei Perlrandschalen und einem bronzenen Kettenverteiler entdeckt. Der Fund wurde 2017 als Block geborgen und im Labor der Kantonsarchäologie Zürich freigelegt. Es handelt sich um zwei Perlrandschalen vom Typ Hohmichele, zwischen die ein gänzlich erhaltener Kettenverteiler eingebettet war. Weitere Funde sind nicht vorhanden und der Fundkomplex scheint nachträglich verlagert worden zu sein. Aufgrund von Vergleichsfunden mit Ha D1/ D2-zeitlichen Wagengräbern im süddeutschen Raum wird angenommen, dass der Fundkomplex ursprünglich im Kontext eines hallstattzeitlichen Grabinventars stand. Der Fundkomplex unterstreicht die Bedeutung des Üetlibergs als »Fürstensitz« in der Hallstattzeit.

description: We present EIS/Hinode & SUMER/SoHO joint observations allowing the first spectroscopic detection of accelerating disturbances as recorded with coronal lines in inter-plume and plume regions of a polar coronal hole. From time-distance radiance maps, we detect the presence of propagating disturbances in a polar inter-plume region with a period of 15 to 20 min and a propagation speed increasing from 130+/-14 km/s just above the limb, to 330+/-140 km/s around 160" above the limb. These disturbances can also be traced to originate from a bright region of the on-disk part of the coronal hole where the propagation speed was found to be in the range of 25+/-1.3 to 38+/-4.5 km/s, with the same periodicity. These on-disk bright regions can be visualized as the base of the coronal funnels. The adjacent plume region also shows the presence of propagating disturbance with the same range of period but with propagation speeds in the range of 135+/-18 to 165+/-43 km/s only. To our knowledge, this result provides first spectroscopic evidence of acceleration of propagating disturbances in the polar region close to the Sun (within 1.2 solar radii). We suggest that the waves are likely either Alfv'enic or fast magnetoacoustic in the inter-plume and slow magnetoacoustic in plume regions. This may lead to the conclusion that inter-plumes are preferred channel for the acceleration of the fast solar wind.

description: Hitherto, fewer than 250 finds of bronze body armour of various shapes and types are known from the European Bronze Age – a rather low number compared with the several thousands of contemporaneous swords, axes and daggers. Of these, roughly 30 cuirasses, 50 Western European helmets and 70 Eastern European helmets are securely dated to the Bronze Age, whilst some of the c. 75 greaves found to date are attributed to the Early Iron Age. Unfortunately, few of these finds are held by museums. This article focuses on two topics: Firstly, we discuss a case of four pieces of horse armour, together with two helmets, identified from one of the confiscated archives belonging to a previously »reputable« antiquities dealer. The horse armour was not associated with the helmets before this study and all six objects still reside at the Getty Museum. Secondly, we will discuss 13 further finds of Bronze Age helmets and a pair of greaves, mostly unpublished, and we present an update of current whereabouts of other Bronze Age helmets on the market. Based on the information available to us, it is important to point out that none of the newly presented finds derives from an official archaeological excavation.

description: Let p\in\{2,3\}, and let k be an imaginary quadratic field in which p decomposes into two distinct primes \mathfrak{p} and \bar{\mathfrak{p}}. Let k_\infty be the unique Z_p-extension of k which is unramified outside of \mathfrak{p}, and let K_\infty be a finite extension of k_\infty, abelian over k. We prove that in K_\infty, the projective limit of the p-class group and the projective limit of units modulo elliptic units share the same μ-invariant and the same λ-invariant. Then we prove that up to a constant, the characteristic ideal of the projective limit of the p-class group coincides with the characteristic ideal of the projective limit of units modulo elliptic units.

description: In 2016, the Windsor Public Library Board (WPLB) purchased an abandoned historic fire hall and stable and through an extensive and challenging adaptive reuse project, opened the John Muir Branch in September 2019. Designed by architect, composer and heritage professional Jason Grossi, the space offers unique acoustics and modern aesthetics that honour the original character of the heritage building. The case study considers the challenges faced in revitalising the building and how the public library has provided an innovative space to support the needs of the community and 21st century library users.
A Golod-Shafarevich Equality and p-Tower Groups

description: All current techniques for showing that a number field has an infinite p-class field tower depend on one of various forms of the Golod-Shafarevich inequality. Such techniques can also be used to restrict the types of p-groups which can occur as Galois groups of finite p-class field towers. In the case that the base field is a quadratic imaginary number field, the theory culminates in showing that a finite such group must be of one of three possible presentation types. By keeping track of the error terms arising in standard proofs of Golod-Shafarevich type inequalities, we prove a Golod-Shafarevich equality for analytic pro-p-groups. As an application, we further work of Skopin, showing that groups of the third of the three types mentioned above are necessarily tremendously large.

description: The Berglibalm rock shelter is located in the municipality of Muotathal in the Bisistal valley at an altitude of 1140 m a. s. l. The areas excavated in 2015 and 2019 measured 5 m2 and yielded the remains of an Early Mesolithic layer dating from around 8766 to 7596 BC. The charcoal concentrations recorded showed that hazel and maple were the main species used for firewood. The excavation also unearthed many well-preserved faunal remains, a small quantity of plant macrofossils and a lithic assemblage comprising 535 artefacts including 15 microliths. The raw material analysis revealed that the hunter-gatherers preferred local and regional raw materials including fine-grained quartzite (»Ölquarzit«). Some long-distance imports attested to contacts to the Chur and Vorarlberg regions in the east, the Ticino in the south and the Upper Rhine Valley or southern Black Forest region in the north. The rock shelter served as a campsite for Mesolithic hunters targeting ibex, chamois, deer and wild boar deep in the Bisistal valley.
