description: When electrons are confined in two-dimensional (2D) materials, quantum mechanically enhanced transport phenomena, as exemplified by the quantum Hall effects (QHE), can be observed. Graphene, an isolated single atomic layer of graphite, is an ideal realization of such a 2D system. Here, we report an experimental investigation of magneto transport in a high mobility single layer of graphene. Adjusting the chemical potential using the electric field effect, we observe an unusual half integer QHE for both electron and hole carriers in graphene. Vanishing effective carrier masses is observed at Dirac point in the temperature dependent Shubnikov de Haas oscillations, which probe the 'relativistic' Dirac particle-like dispersion. The relevance of Berry's phase to these experiments is confirmed by the phase shift of magneto-oscillations, related to the exceptional topology of the graphene band structure.

description: It was recently shown that different simple models of glass formers with binary interactions define a universality class in terms of the density of states of their quasi-localized low-frequency modes. Explicitly, once the hybridization with standard Debye (extended) modes is avoided, a number of such models exhibit a universal density of state, depending on the mode frequencies as $D(ω) \sim ω^4$. It is unknown however how wide is this universality class, and whether it also pertains to more realistic models of glass formers. To address this issue we present analysis of the quasi-localized modes in silica, a network glass which has both binary and ternary interactions. We conclude that in 3-dimensions silica exhibits the very same frequency dependence at low frequencies, suggesting that this universal form is a generic consequence of amorphous glassiness.

description: Removal of uranium(VI) by zero-valent iron (ZVI) has been suggested as a feasible pathway to control uranium contaminations in seepage waters. Available information in literature however presents discrepant evidence on the process responsible for the mitigation effect. On basis of an EH-pH diagram of uranium and iron it is outlined that these discrepancies may be explained by the aqueous chemistry of uranium and iron. Additional effects contributing to the complexity of the system are given. Solubilization experiments using scrap iron together with water works sludge, MnO2 and pyrite indicate that U(VI) is immobilized by iron corrosion products after about 50 days.
Echoes of Tourism: Exploring the Ecological Effects of Habituation in Alpine Wildlife
Creators: name: Ricketts, Macy
Publisher: name: QUBES Educational Resources
Year: 2025

description: Using the Ecological Society of America’s 4DEE (Four-Dimensional Ecology Education) framework, this field activity explores the ecological consequences of habituation—defined as a decreased animal response to human stimuli—on alpine wildlife in national parks. Students participating in the alpine ecology field course engage in structured animal behavior observations to investigate how human activities, such as recreation and tourism, impact wildlife behavior and interactions. By conducting observations at different times of day, these students collect data on animal responses to varying levels of human presence. This data serves as the foundation for final research projects focused on hypothesis generation, data analysis, and ecological interpretation.

Pre- and post-activity lectures connect habituation to broader ecological concepts, including predator-prey dynamics, resource availability, and ecosystem structure. Class discussions emphasize ethical considerations in conservation and the responsibility of humans in protected areas, fostering awareness of how behavioral shifts in wildlife can lead to cascading ecological impacts. Additionally, this activity connects to the Food-Energy-Water (FEW) nexus by examining how human activities impact alpine ecosystem resources, affecting animal behavior and resource distribution. This activity, which can be adapted to fit a variety of course formats, highlights the need for mindful management strategies that mitigate human influence on vulnerable alpine ecosystems.

description: The ability to acquire water from the soil is a major driver in interspecific plant competition and it depends on several root functional traits. One of these traits is the excretion of gel-like compounds (mucilage) that modify physical soil properties. Mucilage secreted by roots becomes hydrophobic upon drying, impedes the rewetting of the soil close to the root, the so called rhizosphere, and reduces water availability to plants. The function of rhizosphere hydrophobicity is not easily understandable when looking at a single plant, but it may constitute a competitive advantage at the ecosystem level. We hypothesize that by making the top soil hydrophobic, deep-rooted plants avoid competititon with shallow-rooted plants. To test this hypothesis we used an individual-based model to simulate water uptake and growth of two virtual plant species, one deep-rooted plant capable of making the soil hydrophobic and a shallow-rooted plant. We ran scenarios with different precipitation regimes ranging from dry to wet (350, 700, and 1400 mm total annual precipitation) and from high to low precipitation frequencies (1, 7, and 14 days). Plant species abundance and biomass were chosen as indicators for competitiveness of plant species. At constant precipitation frequency mucilage hydrophobicity lead to a benefit in biomass and abundance of the tap-rooted population. Under wet conditions this effect diminished and tap-rooted plants were less productive. Without this trait both species coexisted. The effect of root exudation trait remained constant under different precipitation frequencies. This study shows that mucilage secretion is a competitive trait for the acquisition of water. This advantage is achieved by the modification of the soil hydraulic properties and specifically by inducing water repellency in soil regions which are shared with other species.

description: Between 12 and 19 December, five data logger deployments on four different birds.
One bird at Nugget Point was fitted with camera & GPS dive loggers but lost both devices over night and was refitted with a new GPS dive logger. The device was recovered five days later but had not left its nest during the deployment period.
Three birds at Te Rere were fitted with GPS dive loggers; device recovery is scheduled for Boxing Day.
At all Catlins sites, most nests have already entered post-guard despite chicks still being rather small (2-3 weeks old) indicating poor foraging conditions. Nest numbers are down at all sites.
Information-Theoretic Generalization Bounds for Meta-Learning and Applications

description: Meta-learning, or "learning to learn", refers to techniques that infer an inductive bias from data corresponding to multiple related tasks with the goal of improving the sample efficiency for new, previously unobserved, tasks. A key performance measure for meta-learning is the meta-generalization gap, that is, the difference between the average loss measured on the meta-training data and on a new, randomly selected task. This paper presents novel information-theoretic upper bounds on the meta-generalization gap. Two broad classes of meta-learning algorithms are considered that uses either separate within-task training and test sets, like MAML, or joint within-task training and test sets, like Reptile. Extending the existing work for conventional learning, an upper bound on the meta-generalization gap is derived for the former class that depends on the mutual information (MI) between the output of the meta-learning algorithm and its input meta-training data. For the latter, the derived bound includes an additional MI between the output of the per-task learning procedure and corresponding data set to capture within-task uncertainty. Tighter bounds are then developed, under given technical conditions, for the two classes via novel Individual Task MI (ITMI) bounds. Applications of the derived bounds are finally discussed, including a broad class of noisy iterative algorithms for meta-learning.

Towards an analysis of Yorùbá conditionals : its implications for the phrase structure
Creators: name: Barczak, Leszek Krzysztof
Publisher: name: University of British Columbia
Year: 2011

description: This study presents an analysis of conditional constructions in Yorùbá, as well as its implications for language-specific phenomena which are part of the Yorùbá phrase structure. Specifically, I propose a model for the interpretation of conditionals that is based on a tripartite quantificational structure. It is an explanatory model capturing the interdependency between meaning and form. It accounts not only for the Yorùbá data, but also for those in other languages (English, French, Italian and Polish), allowing at the same time for making crosslinguistic predictions. Crucially, the model reflects both: (i) CONDITION (restrictor)-RESULT (nuclear scope) partition of conditional constructions and (ii) existence of two situation factors: (UN)LIKELIHOOD OF SATISFACTION and TIME OF CONDITION, which play pivotal role in meaningform mapping. Note that, even though both factors contribute to overall interpretation, forms attested are a direct reflection of ways in which languages manipulate these factors in the process of mapping meaning onto form. E.g.: active UNLIKELIHOOD OF SATISFACTION yields two types of conditionals (REALIS and IRREALIS) in Yorùbá, while the three forms attested in the Standard Average European languages (INDICATIVE, NON-PAST SUBJUNCTIVE and PAST SUBJUNCTIVE) result from LIKELIHOOD OF SATISFACTION and TIME OF CONDITION being equally active. The above translates further onto differences in morpho-syntactic marking of conditional forms due to the fact that (UN)LIKELIHOOD OF SATISFACTION and TIME OF CONDITION factors are realised on the surface as Mood and Tense respectively. Moreover, this analysis of conditionals provides important insights into the PHRASE STRUCTURE of Yorùbá. It explains: (i) structural complexity of the future marker yóò which spans across the Mood, Time (Tense/Aspect) and Modal categories; (ii) meaning differences expected between the three future markers: yóò, ˋ á and máa (known for its aspectual readings) and based on their internal elements; (iii) the status of the High Tone Syllable - the Time (Tense/Aspect) marker; (iv) dialectal differences - future being marked by irrealis marker in Moba; and so on. I also argue that there exist two system-specific binary oppositions: (i) MARKEDNESS OPPOSITION(S) that specifies tonal value within each syntactic category and (ii) TONE POLARITY that determines tonal melody between adjacent syntactic categories.

A New, Simple Model for Black Hole High Frequency QPOs

Year: 2004
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: Observations of X-ray emissions from binary systems have always been considered important tools to test the validity of General Relativity in strong-field regimes. The pairs and triplets of high frequency quasi-periodic oscillations observed in binaries containing a black hole candidate, in particular, have been proposed as a means to measure more directly the black hole properties such as its mass and spin. Numerous models have been suggested over the years to explain the QPOs and the rich phenomenology accompanying them. Many of these models rest on a number of assumptions and are at times in conflict with the most recent observations. We here propose a new, simple model in which the QPOs result from basic p-mode oscillations of a non-Keplerian disc of finite size. We show that within this new model all of the key properties of the QPOs: a) harmonic ratios of frequencies even as the frequencies change; b) variations in the relative strength of the frequencies with spectral energy distribution and with photon energy; c) small and systematic changes in the frequencies, can all be explained simply given a single reasonable assumption.

description: Molten I-type cosmic spherules formed by heating, oxidation and melting of extraterrestrial Fe,Ni metal alloys. The entire oxygen in these spherules sources from the atmosphere. Therefore, I-type cosmic spherules are suitable tracers for the isotopic composition of the upper atmosphere at altitudes between 80 and 115 km. Here we present data on I-type cosmic spherules collected in Antarctica. Their composition is compared with the composition of tropospheric O2. Our data suggest that the Earth's atmospheric O2 is isotopically homogenous up to the thermosphere. This makes fossil I-type micrometeorites ideal proxies for ancient atmospheric CO2 levels.

description: We set out to look at the overlap between CHEOPS sky coverage and TESS primary mission monotransits to determine what fraction of TESS monotransits may be observed by CHEOPS. We carry out a simulation of TESS transits based on the stellar population in TICv8 in the primary TESS mission. We then select the monotransiting candidates and determine their CHEOPS observing potential. We find that TESS will discover approximately 433 monotransits during its primary mission. Using a baseline observing efficiency of 40% we then find that 387 of these ($\sim$89%) will be observable by CHEOPS with an average observing time of $\sim$60 days per year. Based on the individual observing times and orbital periods of each system we predict that CHEOPS could observe additional transits for approximately 302 of the 433 TESS primary mission monotransits ($\sim$70%). Given that CHEOPS will require some estimate of period before observing a target we estimate that up to 250 ($\sim$58%) TESS primary mission monotransits could have solved periods prior to CHEOPS observations using a combination of photometry and spectroscopy.

description: In the article a convergent numerical method for conservative solutions of the Hunter--Saxton equation is derived. The method is based on piecewise linear projections, followed by evolution along characteristics where the time step is chosen in order to prevent wave breaking. Convergence is obtained when the time step is proportional to the square root of the spatial step size, which is a milder restriction than the common CFL condition for conservation laws.

description: This report explores export competitiveness of soybeans and corn in Argentina, Brazil, and the United States by comparing farm-level production costs, the cost of internal transportation and handling, and the cost of shipping to a common export destination. In addition, prices received by farmers and average yields for each crop in each country are analyzed to calculate producer returns. Errata: This report was revised in July 2016 by correcting table 5, which now corresponds with the text. The table includes two Brazilian regions for each commodity, additional rows that show two components of the farm price, and the correct transportation costs for Brazil.
title: The sociology of recurrent ceremonial drama: Lewes Guy Fawkes Night, 1800-1913
Creators: name: Etherington, James Edward
Publisher: name: The Open University
Year: 1988

description: Social phenomena can be best understood through an interdisciplinary approach involving history and the social sciences that brings together structural forces and the human agency. This contention is critically examined in the present thesis by establishing a symbiotic relationship between historical, sociological and anthropological accounts of social custom, ceremony and disturbance through the analysis of the Lewes Guy Fawkes Night celebrations as a recurrent ceremonial drama. This strategy demonstrates the gradual process of change within Lewes, as reflected in the slowly evolving form of the celebrations, indicating the existence of a relatively stable community touched, but not radically altered, by industrial or urban development. As a consequence, it is argued, the development of class conflict and class consciousness did not occur. Rather, expressions of 'popular conservatism' and community orientation remained the dominant modes of expression throughout the latter half of the century. Empirical evidence both supports this conclusion and proffers an alternative. Using the social drama model, it is shown how two periods of opposition to the celebrations bring into focus the sources of tension and the contending factions. The analysis of the motives and ideologies expressed at these times identifies a similarity between those of the working class "bonfire boys" and of their middle class supporters which, while not totally negating class interpretations of conflict surrounding social customs, do undermine it as a single explanation. From this it is argued that the neighbourhood orientation of the bonfire societies provides an alternative explanation, a sense of community rather than class conflict motivating the participants. The reconstruction of extensive social networks among the "bonfire boys" stresses the relationships upon which community as a social entity arises, the durability of the celebrations being attributable to a desire to reaffirm these relationships. The activities of the bonfire boys are thus expressions of community, rather than class solidarity.
A unified view of curvature and torsion in metric-affine gauge theory of gravity through affine-vector bundles

description: One of the most appealing results of metric-affine gauge theory of gravity is a close parallel between the Riemann curvature two-form and the Cartan torsion two-form: While the former is the field strength of the Lorentz-group connection one-form, the latter can be understood as the field strength of the coframe one-form. This parallel, unfortunately, is not fully established until one adopts Trautman's idea of introducing an affine-vector-valued zero-from, the meaning of which has not been satisfactorily clarified. This paper aims to derive this parallel from first principles without any ad hoc prescriptions. We propose a new mathematical framework of an associated affine-vector bundle as a more suitable arena for the affine group than a conventional vector bundle, and rigorously derive the covariant derivative of a local section on the affine-vector bundle in the formal Ehresmann-connection approach. The parallel between the Riemann curvature and the Cartan torsion arises naturally on the affine-vector bundle, and their geometric and physical meanings become transparent. The clear picture also leads to a conjecture about a kinematical effect of the Cartan torsion that in principle can be measured à la the Aharonov-Bohm effect.

description: Power control is becoming increasingly essential for the fifth-generation (5G) and beyond systems. An example use-case, among others, is the unmanned-aerial-vehicle (UAV) communications where the nearly line-of-sight (LoS) radio channels may result in very low signal-to-interference-plus-noise ratios (SINRs). Investigations in [1] proposed to efficiently and reliably solve this kind of non-convex problem via a series of geometrical programmings (GPs) using condensation approximation. However, it is only applicable for a small-scale network with several communication pairs and practically infeasible with more (e.g. tens of) nodes to be jointly optimized. We therefore in this paper aim to provide new insights into this problem. By properly introducing auxiliary variables, the problem is transformed to an equivalent form which is simpler and more intuitive for condensation. A novel condensation method with linear complexity is also proposed based on the form. The enhancements make the GP-based power control feasible for both small-and especially large-scale networks that are common in 5G and beyond. The algorithm is verified via simulations. A preliminary case study of uplink UAV communications also shows the potential of the algorithm.

The effects of vitronectin at sites of myocardial ischemia and infarction
Creators: name: Walinski, Hubert Paul
Publisher: name: University of British Columbia
Year: 2011

description: Myocardial infarction (MI) results from the thrombotic occlusion of an atherosclerotic coronary artery in patients with ischemic heart disease. The plasminogen activator (PA)/plasmin system plays significant roles in events leading to wound healing following MI. Vitronectin (VN) is an acute phase plasma protein which has a direct influence over the constituents of the plasminogen activator/plasmin system. However, the effects of VN on cardiac function and wound healing following ischemia and infarction remain to be elucidated. My dissertation addresses the investigation of the specific role of VN at sites of myocardial ischemia, infarction and fibrosis. More specifically, my work focused on the function of VN in modulation of cardiomyocyte contractility, its effects on cardiac function, and regulation of extracellular matrix degradation in ischemic and infarcted hearts. In vitro and in vivo models have been employed to study the detailed role of VN at sites of ischemia and infarction. Isolated neonatal and adult rat cardiomyocytes, as well as left anterior descending (LAD) coronary artery-ligated transgenic mice have been used to investigate post-MI function and left ventricular (LV) healing. The main findings in this work include the demonstration that during ischemia and infarction VN modulates post-MI myocardial repair/remodeling and cardiac function. VN enters ischemic cardiomyocytes and binds to sarcomeric desmin intermediate filaments apparently causing significant reduction in cardiomyocyte contractility. Further, following infarction VN affects myocardial wound healing by regulating the PA/plasmin and matrix metalloproteinase systems. As well, exercise training in a rat model of LAD ligation induced cardiomyocytes to synthesize and secrete tissue-type plasminogen activator, which may have a role in myocardial healing post-MI. My work on myocardial healing and repair in experimental MI models indicates a potentially important role for plasma proteins such as VN on the PA/plasmin system.

description: Risk-based authentication (RBA) is an adaptive security measure to strengthen password-based authentication. RBA monitors additional implicit features during password entry such as device or geolocation information, and requests additional authentication factors if a certain risk level is detected. RBA is recommended by the NIST digital identity guidelines, is used by several large online services, and offers protection against security risks such as password database leaks, credential stuffing, insecure passwords and large-scale guessing attacks. Despite its relevance, the procedures used by RBA-instrumented online services are currently not disclosed. Consequently, there is little scientific research about RBA, slowing down progress and deeper understanding, making it harder for end users to understand the security provided by the services they use and trust, and hindering the widespread adoption of RBA. In this paper, with a series of studies on eight popular online services, we (i) analyze which features and combinations/classifiers are used and are useful in practical instances, (ii) develop a framework and a methodology to measure RBA in the wild, and (iii) survey and discuss the differences in the user interface for RBA. Following this, our work provides a first deeper understanding of practical RBA deployments and helps fostering further research in this direction.

Kompetensutveckling som styrning. Om statliga insatser för lärares kompetensutveckling och hur de förhandlas i lärares lokala praktik (Professional development as a policy instrument. State initiatives for teachers’ professional development and how they are negotiated in teachers’ local practice)

description: Teachers’ professional development (PD) is currently promoted as an important element of the pursuit of improved school results by researchers, politicians, and international organizations. Policy actors argue that the quality of teaching is the factor within school systems with the greatest significance for students’ learning outcomes, and that PD is an important instrument for enhancing such quality. Teachers’ PD has also become a higher priority among policy makers due to decentralization reforms that have deprived states of many of the policy measures previously available to them. However, teachers’ PD has rarely been investigated as a policy instrument. This is unfortunate for several reasons, including that surrounding governance structures are important for the effects of PD, and that most of the PD in which teachers partake is initiated by actors such as states, municipalities, or school leadership. Based on these arguments, the aim of this thesis is to develop knowledge about how teachers’ PD functions as an instrument for governing teachers’ work. The dissertation explores this issue through a comparative investigation of state initiatives for teachers’ PD in Sweden during the period 1991-2015. The dissertation devotes special attention to one intervention, the Literacy Boost (in Swedish Läslyftet), by also investigating its enactment at six schools during the 2015/16 academic year. The thesis shows that the Swedish state’s spending for teachers’ PD and school development increased significantly during the investigated period, especially after 2007, and, likewise, that teachers’ participation in PD increased. Moreover, article I shows that school agencies, since 1991, increased their engagement in teachers’ PD, that PD prescriptions became more detailed, and that evaluations of local enactment were used in more comprehensive ways. Based on the local enactment of the Literacy Boost, articles II and III illuminated the difficulty of translating external and cross-curricular messages to teachers’ local practice. While the PD model’s form of governance effectively induced teachers to discuss and enact instructions in the PD material, enactments took the form of additional activities rather than being made coherent with teachers’ present subject teaching. Thus, articles II and III indicated that, in order for PD messages to contribute to teaching, governance should be more specific to teachers’ present practice. Lastly, the dissertation illuminates a paradox regarding state-initiated PD in decentralized school systems. Although decentralization increases the state’s incentives to engage in teachers’ PD, the state’s ability to adapt PD initiatives to local needs is limited by the principles of decentralization.

description: Aus unterkarnischen Cipit-Kalken (Cassianer Schichten) wird eine artenarme Faunula rigider Kieselschwiin.ne beschrieben. Erstmalig fur die Trias gelingt der Nachweis komplett erhaltener lithistider Schwanvne. Sie inkrustieren als sekundare Gerustbildner die abgestorbenen corallinen Spongien. Im Gegensatz dazu siedeln die Hexactinelliden im Weichboden der Mud mounds. Das bisher fragwurdige Vorkonvnen der hexactinelliden Gattung Casearia in der Trias wird gesichert belegt. Die schlechte Erhaltung der nur im Dunnschliff erkennbaren Kieselschwamme erlaubt jedoch keine weitreichenden systematischen Aussagen.
description: A small, low divers ity fauna of sponges with r i gid primary si 1 iceous skeletons is described from the socalled "Cipit-Boulders" of Lower Carnian age (Cassian Beds, Northern Italy). Completely preserved lithistid sponges of Triassic age are described for the first time. They grew on calcareous skeletons of dead coralline sponges within mud mounds. In contrast, hexactinellid sponges settled on the soft mud between the other reef dwellers. The questionable occurrence of the hexactinellid genus Casearia in the Triassic is now confirmed. Owing to the poor preservation of the calcified siliceous sponges, which can only be recognized in thin sections, evidence for specific systematic determinations is limited.
