Publisher: name: University of Dundee

description: Online and technology enhanced delivery are not conventional practices in art and design education and the attitude of design students towards this is largely underexplored. This research therefore explores the phenomenon of online learning and teaching in the context of Scotland’s newest university, University of the Highlands, and Islands (UHI). The research evaluates existing provision of online learning and explores the potential of a blended or hybrid approach to learning and teaching as a future proposition within the context of the Creative Industries curriculum of the University of the Highlands and Islands (UHI). The research was undertaken with a view to inform UHI’s future holistic and strategic approach to Creative Industries curriculum development; initial lecturer training; and to connect communities enabling wider access and collaboration within the Highlands and Islands of Scotland and internationally. The research reviews the blended learning and hybrid approach pre COVID-19, during and post the pandemic and the impact on future delivery of art and design education within UHI. The research reported here explored the development of learners’ competences in online and blended design education in a longitudinal, qualitative study. The research discusses emergent themes such as roles of learner autonomy, communities, and networks. This thesis reviews theories and signature pedagogies in relation to art & design education whilst examining the potential of an optimum blended course. Creativity as a key competency forms a compelling rationale for the effective preparation of an ‘optimum blend’ of delivery related to art and design education. The findings in this thesis make a further persuasive case for hybrid and blended learning and teaching to be considered and designed. The thesis raises awareness of the benefits of art and design education in UHI and beyond. The findings present the hybrid studio as an interchange between internal and external factors in blended design education. Art and design students graduate and enter inspiring, sustainable, and fulfilling careers in the vibrant cultural and creative industries.

description: Im Rahmen der vorliegenden Arbeit wurde das lichtabhängige Akklimatisations- und Wachstumsverhalten der Grünalge Chlorella vulgaris, die hierbei als Modellorganismus fungierte, auf makroskopischer Ebene experimentell untersucht. Die aus diesen Experimenten gewonnenen Erkenntnisse und Daten wurden anschließend, zusammen mit den stationären Photosynthesekinetiken, als experimentelle Grundlage für die Modellierung der lichtabhängigen Photosynthesekinetik genutzt. Als Modellierungsgrundlage diente hierbei das Konzept der photosynthetic unit (PSU), das im bioverfahrenstechnischen Kontext häufig zur Modellierung der Photosynthesekinetik eingesetzt wird. Im Gegensatz zu der typischen Annahme eines absolut limitierenden Reaktionsschrittes innerhalb der PSU, der die gesamte Photosynthesekinetik definiert, wurde angenommen, dass unterschiedliche limitierende Reaktionen die jeweiligen Bereiche der lichtabhängigen Photosynthesekinetik definieren. Im Rahmen des hier entwickelten Modells wurde festgelegt, dass der lichtlimitierte Bereich der Photosynthesekinetik hauptsächlich durch die Lichtabsorption und die Prozessierung der Lichtenergie am Photosystem II determiniert wird, während ein zweiter limitierender Reaktionsschritt den lichtgesättigten Bereich der Photosynthesekinetik determiniert. Weiterhin wurde angenommen, dass die beiden limitierenden Reaktionsschritte über den Plastochinon-Pool miteinander gekoppelt sind. Unter den im Rahmen der vorliegenden Arbeit untersuchten Prozessbedingungen wurde die Kinetik von Ribulose-1,5-bisphosphat-carboxylase/-oxygenase als die zweite limitierende Reaktion definiert. Durch die Einführung dieser Erweiterungen des gängigen PSU-Konzeptes konnte ein Modell entwickelt werden, dass dem häufig genutzten PSU-Modell nach Han, das hierbei als Referenz diente, deutlich überlegen ist. Weiterhin konnte das in dieser Arbeit entwickelte Modell die operativen Photosyntheseraten im photoakklimatisierten Zustand, die nicht Teil des zur Parameterschätzung genutzten Datensatzes waren, mit einer zufriedenstellenden Genauigkeit vorhersagen (R²: 0,9688, nRMSE: 11,74 % und nMBE: -9,76 %).

description: The standard-model Higgs boson couples to quarks through a parity-even scalar $Hq{\bar q}$ coupling. We show that the rare Higgs decay $H\to VZ$, where $V$ is a vector quarkonium state such as $J/ψ$ ($c{\bar c}$) or $Υ(1S)$ ($b{\bar b}$), can be used to search for the presence of a parity-odd pseudoscalar $Hq{\bar q}$ coupling. Since both $V$ and $Z$ can decay to a pair of charged leptons, this presents an experimentally-clean channel that can be observed at the high-luminosity LHC or a future hadron collider. The P-even and P-odd $Hq{\bar q}$ couplings can be measured by analyzing the angular distribution of the final-state leptons.

On the distances of planetary nebulae

description: We reconsider calibration of statistical distance scales for planetary nebulae, examining precision and systematic error for various distance methods used as well as the scales themselves. A different calibration strategy, one based on precise trigonometric parallaxes by Harris et al. (2007; some improved by Benedict et al. 2009), is presented. Most statistical scales have an overall scale error; in addition, all four tested show dependence of distance ratio [scale/actual] on nebular radius. However, the H-alpha scale of Frew (2008; slightly revised in Frew et al. 2014) has only a small radius dependence at large R and overall is consistent with these parallaxes. Some methods used for calibration have systematic errors, and the extinction method is found to be mostly unreliable. Comparison of Hipparcos parallaxes for a few large planetaries with our "best estimate" distances for those confirms the overestimation of 2.5 found by Harris et al. for PHL 932. We suggest a possible connection with the smaller overestimation found by Melis et al. (2014) when testing Hipparcos parallaxes for some of the Pleiades.

description: The production of a primordial stochastic gravitational-wave background by processes occuring in the early Universe is expected in a broad range of models. Observing this background would open a unique window onto the Universe's evolutionary history. Probes like the Cosmic Microwave Background (CMB) or the Baryon Acoustic Oscillations (BAO) can be used to set upper limits on the stochastic gravitational-wave background energy density $Ω_{GW}$ for frequencies above $10^{-15}$ Hz. We perform a profile likelihood analysis of the Planck CMB temperature anisotropies and gravitational lensing data combined with WMAP low-$\ell$ polarization, BAO, South Pole Telescope and Atacama Cosmology Telescope data. We find that $Ω_{GW}h_{0}^{2} < 3.8 \times 10^{-6}$ at 95\% confidence level for adiabatic initial conditions which improves over the previous limit by a factor 2.3. Assuming that the primordial gravitational waves have been produced by a network of cosmic strings, we have derived exclusion limits in the cosmic string parameter space. If the size of the loops is determined by gravitational back-reaction, string tension values greater than $\sim 4 \times 10^{-9}$ are excluded for a reconnection probability of $10^{-3}$.

description: Since the COVID-19 outbreak, the use of digital learning or education platforms has significantly increased. Teachers now digitally distribute homework and provide exercise questions. In both cases, teachers need to continuously develop novel and individual questions. This process can be very time-consuming and should be facilitated and accelerated both through exchange with other teachers and by using Artificial Intelligence (AI) capabilities. To address this need, we propose a multilingual Wikimedia framework that allows for collaborative worldwide teacher knowledge engineering and subsequent AI-aided question generation, test, and correction. As a proof of concept, we present >>PhysWikiQuiz<<, a physics question generation and test engine. Our system (hosted by Wikimedia at https://physwikiquiz.wmflabs.org) retrieves physics knowledge from the open community-curated database Wikidata. It can generate questions in different variations and verify answer values and units using a Computer Algebra System (CAS). We evaluate the performance on a public benchmark dataset at each stage of the system workflow. For an average formula with three variables, the system can generate and correct up to 300 questions for individual students based on a single formula concept name as input by the teacher.

description: We categorize new physics signatures that manifest themselves as a "dip" structure at colliders. One potential way to realize a dip is to require interactions to be zero when all particles are mass on-shell, but not if one or more are mass off-shell. For three particle interactions, we have found three interesting cases: one massive gauge boson with two identical scalars; one massless gauge boson with two different scalars; one massive gauge boson with two identical massless gauge bosons. For each case, we identify the relevant effective operators to explore its dip signature at the LHC. Unfortunately, the unstable particle with a vanishing mass-on-shell interaction has a complex mass which is coincident with the complex pole in its propagator. As a result, a contact-like amplitude without a dip is produced. We then point out two other interesting ways that generate a dip in the cross section. The first way has a dip signature due to a zero in the vertex form factor of the time-like momentum in the s-channel. In the second way, the dip plus bump signature appears because there is destructive interference among processes of exchanging different s-channel particles.

Fibronectin molecule visualized in electron microscopy: a long, thin, flexible strand

description: We have determined the structure of plasma fibronectin by electron microscopy of shadowed specimens. the 440,000 molecular weight, dimeric molecule appears to be a long, thin, highly flexible strand. The contour length of the most extended molecules is 160 nm, but a distribution of lengths down to 120 nm was observed, indicating flexibility in extension as well as in bending. The average diameter of the strand is 2 nm and there are no large globular domains. the large fragments produced by limited digestion with plasmin are not globular domains but are segments of the strand, whose length corresponds to the molecular weight of the polypeptide chain. We conclude that each polypeptide chain of the dimeric molecule spans half the length of the strand, with their carboxyl termini joined at the center of the strand and their amino termini at the ends. This model is supported by images of fibronectin-fibrinogen complexes, in which the fibrinogen is always attached to an end of the fibronectin strand.

description: Sampling-based methods are widely adopted solutions for robot motion planning. The methods are straightforward to implement, effective in practice for many robotic systems. It is often possible to prove that they have desirable properties, such as probabilistic completeness and asymptotic optimality. Nevertheless, they still face challenges as the complexity of the underlying planning problem increases, especially under tight computation time constraints, which impact the quality of returned solutions or given inaccurate models. This has motivated machine learning to improve the computational efficiency and applicability of Sampling-Based Motion Planners (SBMPs). This survey reviews such integrative efforts and aims to provide a classification of the alternative directions that have been explored in the literature. It first discusses how learning has been used to enhance key components of SBMPs, such as node sampling, collision detection, distance or nearest neighbor computation, local planning, and termination conditions. Then, it highlights planners that use learning to adaptively select between different implementations of such primitives in response to the underlying problem's features. It also covers emerging methods, which build complete machine learning pipelines that reflect the traditional structure of SBMPs. It also discusses how machine learning has been used to provide data-driven models of robots, which can then be used by a SBMP. Finally, it provides a comparative discussion of the advantages and disadvantages of the approaches covered, and insights on possible future directions of research.

A pair of CO + He white dwarfs as the progenitor of 2005E-like supernovae?

description: Ca-rich transients (CRTs, 2005E-like supernovae) exhibit unusually strong Ca features during their nebular phase, and their distribution in their host galaxies indicates that they belong to a metal-poor old population. We carried out a series of binary population synthesis and presented four different channels of forming CO WD + He WD pairs. We selected the systems fulfilling the constraints of the old population and the birth rate from all the CO WD + He WD pairs by constraining the component mass of the WD pairs. For the four channels, the stable Roche lobe overflow (RLOF) could have a significant influence on the formation of the WD + WD pairs. Based on their position on the $M_{\rm CO}$-$M_{\rm He}$ plane, the mass-transfer between the components for most of the CO WD + He WD pairs is neither always unstable nor always stable. We found that it is necessary that the CO WDs are less massive than 0.6 $M_{\odot}$ and the He WDs are less massive than 0.25 $M_{\odot}$ if CO WD + He WD pairs fulfill the constraints from both the old population and the birth rate of CRTs. However, the He WD mass is lower than, while the total mass of the low-mass WD pairs is larger than{\bf ,} the ejecta mass of the CRTs derived from observations. Our results imply that the CO WDs participate in CRT explosions and at the same time, a bound remnant could be left after the CRT explosion if the low-mass WD pairs are the progenitors of CRTs. Therefore, whether or not the helium detonation on a low-mass CO WD may lead to the second detonation in the center of the CO WDs, and whether or not the binding remnant is left after the thermonuclear explosion should be examined carefully in the future.

Motion of particles adhering to the leading lamella of crawling cells

Year: 1981

description: Time-lapsed films of particle motion on the leading lamella of chick heart fibroblasts and mouse peritoneal macrophages were analyzed. The particles were composed of powdered glass or powdered aminated polystyrene and were 0.5-1.0 micrometer in radius. Particle motions were described by steps in position from one frame to the time-lapse movies to the next. The statistics of the step-size distribution of the particles were consistent with a particle in Brownian motion subject to a constant force. From the Brownian movement, we have calculated the two-dimensional diffusion coefficient of different particles. These vary by more than an order of magnitude (10(-11)-10(-10) cm2/s) even for particles composed of the same material and located very close to each other on the surface of the cell. This variation was not correlated with particle size but is interpretable as a result of different numbers of adhesive bonds holding the particles to the cells. The constant component of particle movement can be interpreted as a result of a constant force acting on each particle (0.1-1.0 x 10(-8) dyn). Variations in the fractional coefficient for particles close to each other on the cell surface do not yield corresponding differences in velocity, suggesting that the frictional coefficient and the driving force vary together. This is consistent with the hypothesis that the particles are carried by flow of the membrane as a whole or by flow of some submembrane material. The utility of our methods for monitoring cell motile behavior in biologically interesting situations, such as a chemotactic gradient, is discussed.

description: Observations reveal a strong structural coupling between bulge and disc in S0 galaxies, which seems difficult to explain if they have formed from supposedly catastrophic events such as major mergers. We face this question by quantifying the bulge-disc coupling in dissipative simulations of major and minor mergers that result in realistic S0s. We have studied the dissipative N-body binary merger simulations from the GalMer database that give rise to realistic, relaxed E/S0 and S0 remnants (67 major and 29 minor mergers). We simulate surface brightness profiles of these S0-like remnants in the K-band, mimicking typical observational conditions, to perform bulge-disc decompositions analogous to those carried out in real S0s. The global bulge-disc structure of these remnants has been compared with real data, and they distribute in the B/T - r_e - h_d parameter space consistently with real bright S0s, where B/T is the bulge-to-total luminosity ratio, r_e is the bulge effective radius, and h_d is the disc scalelength. Major mergers can rebuild a bulge-disc coupling in the remnants after having destroyed the structures of the progenitors, whereas minor mergers directly preserve them. Remnants exhibit B/T and r_e/h_d spanning a wide range of values, and their distribution is consistent with observations. Many remnants have bulge Sersic indices ranging 1

description: We study dephasing of a superconducting qubit due to quasiparticle tunneling through a Josephson junction. While qubit decay due to tunneling processes is well understood within a golden rule approximation, pure dephasing due to BCS quasiparticles gives rise to a divergent golden rule rate. We calculate qubit dephasing due to quasiparticle tunneling beyond lowest order approximation in coupling between qubit and quasiparticles. Summing up a certain class of diagrams we show that qubit dephasing due to purely longitudinal coupling to quasiparticles leads to a dephasing $\sim \exp(-x(t))$ where $x(t)$ is not linear in time on short time scales while it tends towards a selfconsistent calculated dephasing rate for longer times.

description: It is important to know the decoherence mechanism of a qubit based on Josephson junctions. At low temperatures, as quasiparticle concentration becomes exponentially small, one needs to consider energy transfer from tunneling electrons to other degrees of freedom to find dissipation in Josephson junctions and decoherence in qubits. Here we discuss the energy transfer to two-level systems, i.e. the transitions between two different configurations of ions inside insulating layer separated by a potential barrier. We derive a general equation of motion for the phase difference between two superconducting electrodes and we find a retarded dissipation term due to electromagnetic mechanism and also contribution due to electron tunneling mechanism. Using the equation of motion we calculate the decay of Rabi oscillations and frequency shift in qubits due to the presence of the two-level systems. In the long time limit our results coincide with those obtained by Martinis et al. [J. M. Martinis et al.. Phys. Rev. Lett. 95, 210503 (2005)] within the Fermi's Golden rule approach up to a numerical factor.

description: We present MargNet, a deep learning-based classifier for identifying stars, quasars and compact galaxies using photometric parameters and images from the Sloan Digital Sky Survey (SDSS) Data Release 16 (DR16) catalogue. MargNet consists of a combination of Convolutional Neural Network (CNN) and Artificial Neural Network (ANN) architectures. Using a carefully curated dataset consisting of 240,000 compact objects and an additional 150,000 faint objects, the machine learns classification directly from the data, minimising the need for human intervention. MargNet is the first classifier focusing exclusively on compact galaxies and performs better than other methods to classify compact galaxies from stars and quasars, even at fainter magnitudes. This model and feature engineering in such deep learning architectures will provide greater success in identifying objects in the ongoing and upcoming surveys, such as Dark Energy Survey (DES) and images from the Vera C. Rubin Observatory.

We prove that Rankin-Selberg gamma factor at $s=\frac{1}{2}$ is $γ(\frac{1}{2},π\times π'; ψ) = 1$. The result follows as a simple consequence from the characterisation of $GL_n(\mathbb{R})$-distinguished representations in terms of their Langlands data.

A new protein of adhesion plaques and ruffling membranes

Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 1983

description: A protein with a molecular weight on SDS polyacrylamide gels of 215,000 (referred to here as 215K) was purified from chicken gizzard smooth muscle. Antibodies against this protein localized it in fibroblasts to adhesion plaques (focal contacts), to regions underlying cell surface fibronectin, and to ruffling membranes. In the first two distributions it was similar to vinculin in cellular location, and this was confirmed by double-label immunofluorescence microscopy, but the concentration of 215K in membrane ruffles distinguished it from vinculin. There was no cross-reaction of the antibody against 215K with vinculin, and immunoprecipitation and antibody staining of SDS gels of whole cells revealed a single cross-reactive component with a molecular weight of 215,000. Immunoprecipitation from cultures labeled with [32P]phosphate revealed 215K to be a phosphoprotein. Transformation of rat or chicken fibroblasts by Rous sarcoma virus resulted in a reorganization of 215K, in some cases into complex intracellular structures. The localization of 215K where microfilament bundles terminate as well as in close relation to cell surface fibronectin and in membrane ruffles suggests that the protein has some function in the organization of actin filaments at or close to regions of actin-membrane attachment.

description: The Hubble parameter is a critical measurement in cosmology, which contains the most direct information of the cosmic expansion history. Since discrepancy is found between low redshift and high redshift estimations of Hubble constant, we are interested in whether that tension indicates dynamical dark energy. In this paper we emphasize that the observed Hubble parameters at various redshifts, along with observed Hubble constant, can help us in probing the evolutional behavior of the mysterious dark energy. Null hypothesis tests are carried out with two diagnostic approaches. We find out that, according to the present measurements of Hubble parameters, rejection of constant dark energy is captured at $1σ$ level from null tests with and without the observed value of Hubble constant.

description: Volunteered geographic information (VGI) is often cited as a potential solution to persistent global inequalities in map data, particularly in areas undergoing humanitarian crises. Poor volunteer engagement, slow data production, and low-quality outputs have limited progress, however, and can unintentionally exaggerate inequalities. Hybrid machine learning–VGI (ML–VGI) frameworks can help to overcome these challenges through a combination of workflow automation and purposive human input, but the use of these workflows is rare in practice. Here, we implement an ML–VGI framework (Centaur VGI) and undertake a detailed comparative usability assessment against an existing, widely used VGI mapping platform to demonstrate its potential to improve volunteer engagement, mapping speed, and data quality. Our results suggest that through automated building, searching, and labeling, the Centaur VGI platform provides greater usability, quicker data production, and improved data quality for most users. Consequently, we provide the first evidence that hybrid ML–VGI approaches can be used to facilitate increased public participation in humanitarian building mapping efforts and thus help reduce global inequalities in map data.

description: Air pollution is a major global environmental health threat, in particular for people who live or work near pollution sources. Areas adjacent to pollution sources often have high ambient pollution concentrations, and those areas are commonly referred to as air pollution hotspots. Detecting and characterizing pollution hotspots are of great importance for air quality management, but are challenging due to the high spatial and temporal variability of air pollutants. In this work, we explore the use of mobile sensing data (i.e., air quality sensors installed on vehicles) to detect pollution hotspots. One major challenge with mobile sensing data is uneven sampling, i.e., data collection can vary by both space and time. To address this challenge, we propose a two-step approach to detect hotspots from mobile sensing data, which includes local spike detection and sample-weighted clustering. Essentially, this approach tackles the uneven sampling issue by weighting samples based on their spatial frequency and temporal hit rate, so as to identify robust and persistent hotspots. To contextualize the hotspots and discover potential pollution source characteristics, we explore a variety of cross-domain urban data and extract features from them. As a soft-validation of the extracted features, we build hotspot inference models for cities with and without mobile sensing data. Evaluation results using real-world mobile sensing air quality data as well as cross-domain urban data demonstrate the effectiveness of our approach in detecting and inferring pollution hotspots. Furthermore, the empirical analysis of hotspots and source features yields useful insights regarding neighborhood pollution sources.

description: We propose the intermittently tethered unmanned aerial vehicle (iTUAV) as a tradeoff between the power availability of a tethered UAV (TUAV) and the flexibility of an untethered UAV. An iTUAV can provide cellular connectivity while being temporarily tethered to the most adequate ground anchor. Also, it can flexibly detach from one anchor, travel, then attach to another one to maintain/improve the coverage quality for mobile users. Hence, we discuss here the existing UAV-based cellular networking technologies, followed by a detailed description of the iTUAV system, its components, and mode of operation. Subsequently, we present a comparative study of the existing and proposed systems highlighting the differences in key features such as mobility and energy. To emphasize the potential of iTUAV systems, we conduct a case study, evaluate the iTUAV performance, and compare it to benchmarks. Obtained results show that with only 10 anchors in the area, the iTUAV system can serve up to 90% of the users covered by the untethered UAV swapping system. Moreover, results from a small case study prove that the iTUAV allows to balance performance/cost and can be implemented realistically. For instance, when user locations are clustered, with only 2 active iTUAVs and 4 anchors, achieved performance is superior to that of the system with 3 TUAVs, while when considering a single UAV on a 100 minutes event, a system with only 6 anchors outperforms the untethered UAV as it combines location flexibility with increased mission time.

description: The Indo-Malaysian region is a hot spot of rapid land-cover and land-use change (LCLUC) with little consensus about the rates and magnitudes of such change. Here we use temporal convolutional neural networks (TempCNNs) to generate a spatiotemporally consistent LCLUC data set for nearly thirty-five years (1982–2015), validated against two reference data sets with over 80 percent accuracy, better than other LCLUC products for the region. Our results both confirm and complicate estimates from earlier work that relied on decadal, rather than interannual, changes in regional land cover. We find forests decrease in mainland and maritime Southeast Asia and increase in South China and South Asia. Consistent with geographic theory about the drivers of land-use change, we find cropland expansion is a driving force for deforestation in mainland Southeast Asia with savannas playing a superior role, suggesting widespread forest degradation in this region. In contrast to earlier work and theory, we find that South China’s increasing forest cover comes principally from savanna (rather than cropland) conversion. The explicit interannual LCLUC patterns, rates, and transitions identified in this study provide a valuable data source for studies of land-use theory, environmental and climate changes, and regional land-use policy evaluations.

Phosphate groups modifying myelin basic proteins are metabolically labile; methyl groups are stable

description: Young and adult rats received intracranial injections of [33P]orthophosphoric acid. The time course of the appearance and decay of the radioactive label on basic proteins in isolated myelin was followed for 1 mo. Incorporation was maximal by 1 h, followed by a decay phase with a half-life of approximately 2 wk. However, radioactivity in the acid-soluble precursor pool (which always constituted at least half of the total radioactivity) decayed with a similar half-life, suggesting that the true turnover time of basic protein phosphates might be masked by continued exchange with a long- lived radioactive precursor pool. Calculations based on the rate of incorporation were made to more closely determine the true turnover time; it was found that most of the phosphate groups of basic protein turned over in a matter of minutes. Incorporation was independent of the rate of myelin synthesis but was proportional to the amount of myelin present. Experiments in which myelin was subfractionated to yield fractions differing in degree of compaction suggested that even the basic protein phosphate groups of primarily compacted myelin participated in this rapid exchange. Similar studies were carried out on the metabolism of radioactive amino acids incorporated into the peptide backbone of myelin basic proteins. The metabolism of the methyl groups of methylarginines also was monitored using [methyl- 3H]methionine as a precursor. In contrast to the basic protein phosphate groups, both the peptide backbone and the modifying methyl groups had a metabolic half-life of months, which cannot be accounted for by reutilization from a pool of soluble precursor. The demonstration that the phosphate groups of myelin basic protein turn over rapidly suggests that, in contrast to the static morphological picture, basic proteins may be readily accessible to cytoplasm in vivo.
