description: We establish continuity of the integral representation $y(t)=x(t)+\int_0^th(y(s)) ds$, $t\ge0$, mapping a function $x$ into a function $y$ when the underlying function space $D$ is endowed with the Skorohod $M_1$ topology. We apply this integral representation with the continuous mapping theorem to establish heavy-traffic stochastic-process limits for many-server queueing models when the limit process has jumps unmatched in the converging processes as can occur with bursty arrival processes or service interruptions. The proof of $M_1$-continuity is based on a new characterization of the $M_1$ convergence, in which the time portions of the parametric representations are absolutely continuous with respect to Lebesgue measure, and the derivatives are uniformly bounded and converge in $L_1$.

A moral ordering of supported care : a case study
Creators: name: Wareing, D
Publisher: name: University Of Tasmania
Year: 2023

description: An ethnomethodological approach is used to analyse the natural occurring talk between six support-workers and an allied-health professional as they go about their business of formulating a behavioural management plan for Jane, a woman with a severe intellectual and communication impairment. Using Sacks' (1974) Membership Categorisation Analysis, the thesis explores the way 'Jane' is categorised by the people at the meeting and how these people formulate their own membership to the categories 'SupportWorker' and 'Professional' through situational practices. The first of the three results chapters looks at accounts of choice as formulated during the meeting; the second examines the given-voice that is attributed 'Jane' by support workers; while the third, looks at assignment of the pronoun 'it' to describe Jane. The thesis concludes with a discussion of the findings and limitations of the investigation as they apply to ethnomethodology literature and the Social Model of Disability (Oliver, 1996).

description: We consider twist-1, 2 operators in planar N=6 superconformal Chern-Simons ABJM theory. We derive higher order anomalous dimensions from integrability and test various QCD-inspired predictions known to hold in N=4 SYM. In particular, we show that the asymptotic anomalous dimensions display intriguing remnants of Gribov-Lipatov reciprocity and Low-Burnett-Kroll logarithmic cancellations. Wrapping effects are also discussed and shown to be subleading at large spin.

description: We study the electron transport through a quantum wire under the influence of external time-dependent gate voltages. The wire is modelled by a tight-binding Hamiltonian for which we obtain the current from the corresponding transmission. The numerical evaluation of the dc current reveals that for bichromatic driving, the conductance depends sensitively on the commensurability of the driving frequencies. The current even possesses a discontinuous frequency dependence. Moreover, we find that the conductance as a function of the wire length oscillates with a period that depends on the ratio between the driving frequencies.

Performance Evaluation of High-Resolution Time-of-Flight Cameras
Creators: name: Song, Qiang
Publisher: name: Zenodo
Year: 2021

description: A Time-of-Flight (ToF) camera is a 3D imaging device to perceive the range information between the ToF sensor and the scene for each camera’s imaging plane pixel. It has been about 20 years since the first ToF prototype was invented based on Photonic Mixer Device (PMD) technology. With the breakthrough of the ToF sensor in terms of depth pixel array at the Video Graphics Array (VGA 640 × 480 px) level in recent years, more and more high-resolution ToF cameras are pouring into the market. In this Thesis, five state-of-the-art high-resolution ToF cameras, Azure Kinect, Helio2, L515, S100D, and AD-96TOF1-EBZ, are compared via a series of experiments in terms of several key parameters, such as warm-up time, precision, lateral resolution, range resolution, and flying pixels. Some notable results are as follows: At a distance of 1m from the white panel, the distance measurement of S100D is stable with a fluctuation within 1 mm after being powered up. Azure Kinect, Helio2, and L515 can achieve precision within 2 mm in the measuring range of 0.5 to 3 m. For the point cloud of the white panel generated by L515 at a distance of 1.5m, only a small amount of flying pixel noise exists at the edge.
Properties of Magneto-Hydrodynamic Waves in the Solar Photosphere with Hinode

Year: 2009
Subjects: subject: Solar and Stellar Astrophysics (astro-ph.SR)

description: We report the observations of the magneto-hydrodynamic waves propagating along magnetic flux tubes in the solar photosphere. We identified 20 isolated strong peaks (8 peaks for pores and 12 peaks for inter-granular magnetic structure) in the power spectra of the l.o.s. (line-of-sight) magnetic flux, the l.o.s. velocity, and the intensity for 14 different magnetic concentrations. The observation is performed with the spectro-polarimeter of the Solar Optical Telescope aboard the \emph{Hinode} satellite. The observed phase relation between the magnetic and the photometric intensity fluctuation would not be consistent with that caused by the opacity effect, if the magnetic field strength decreases with height along the oblique line of sight. We suggest that the observed fluctuations are due to longitudinal (sausage mode) and/or transverse (kink mode) MHD waves. The observed phase relation between the fluctuations in the magnetic flux and the velocity is consistent with the superposition of the ascending wave and the descending wave reflected at chromosphere/corona boundary (standing wave). Even with such reflected waves, the residual upward Poynting flux is estimated to be $2.7 \times 10^{6}$ erg cm$^{-2}$ s$^{-1}$ for a case of the kink wave. Seismology of the magnetic flux tubes is possible to obtain various physical parameters from the observed period and amplitude of the oscillations.

CNO driven winds of hot first stars

Year: 2008
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: During the evolution of first stars, the CNO elements may emerge on their surfaces due to the mixing processes. Consequently, these stars may have winds driven purely by CNO elements. We study the properties of such stellar winds and discuss their influence on the surrounding environment. For this purpose, we used our own NLTE models and tested which stellar parameters of the first stars at different evolutionary stages result in CNO winds. If such winds are possible, we calculate their hydrodynamic structure and predict their parameters. We show that, while the studied stars do not have any wind driven purely by hydrogen and helium, CNO driven winds exist in more luminous stars. On the other hand, for very hot stars, CNO elements are too ionized to drive a wind. In most cases the derived mass-loss rate is much less than calculated with solar mixture of elements. This is because wind mass-loss rate in present hot stars is dominated by elements heavier than CNO. We conclude that, until a sufficient amount of these elements is created, the influence of line-driven winds is relatively small on the evolution of hot stars (which are not close to the Eddington limit).

Nature of Ar bonding to small Co_n^+ clusters and its effect on the structure determination by far-infrared absorption spectroscopy

description: Far-infrared vibrational spectroscopy by multiple photon dissociation has proven to be a very useful technique for the structural fingerprinting of small metal clusters. Contrary to previous studies on cationic V, Nb and Ta clusters, measured vibrational spectra of small cationic cobalt clusters show a strong dependence on the number of adsorbed Ar probe atoms, which increases with decreasing cluster size. Focusing on the series Co_4^+ to Co_8^+ we therefore use density-functional theory to analyze the nature of the Ar-Co_n^+ bond and its role for the vibrational spectra. In a first step, energetically low-lying isomer structures are identified through first-principles basin-hopping sampling runs and their vibrational spectra computed for a varying number of adsorbed Ar atoms. A comparison of these fingerprints with the experimental data enables in some cases a unique assignment of the cluster structure. Independent of the specific low-lying isomer, we obtain a pronounced increase of the Ar binding energy for the smallest cluster sizes, which correlates nicely with the observed increased influence of the Ar probe atoms on the IR spectra. Further analysis of the electronic structure motivates a simple electrostatic picture that not only explains this binding energy trend, but also why the influence of the rare-gas atom is much stronger than in the previously studied systems.

title: CO2 Electroreduction on Silver Catalysts Under Controlled Mass Transport Conditions
Creators: name: Gálvez-Vázquez, María de Jesús
Publisher: name: Universität Bern
Year: 2021
Subjects: subject: 540 Chemistry

description: The electrochemical reduction of carbon dioxide (CO2RR) to value-added chemicals using excess intermittent electric power from renewable energy sources is considered a promising approach to mitigate global warming caused by anthropogenic CO2 emissions.

The product selectivity of the CO2RR can be controlled by the chemical nature and the morphology of the catalyst material. Among the various products of the CO2RR, the production of carbon monoxide (CO) is highly desirable because it can be used as feedstock in the Fischer–Tropsch synthesis to produce higher long-chain hydrocarbons and alcohols. Silver is well known as a promising catalyst material for CO production.

Most of the screening experiments to test the activity, selectivity, and stability of an electrocatalyst have been carried out in H-type cell configurations using aqueous electrolytes. However, the low solubility of CO2 in aqueous electrolytes under ambient conditions imposes severe mass transport limitations. This PhD thesis has addressed this challenge, by carrying out classical half-cell measurements in aqueous environments extended to a zero-gap gas-fed electrolyzer. The catalytic properties of two colloidal silver nanomaterials with different morphologies were studied (nanocubes and nanowires).

The electrocatalysts studied herein present high selectivity and activity towards CO formation, e.g., in the case of silver nanocubes, a partial current density of ~625 mA cm−2 and a faradaic efficiency of ~85% for CO were attained. Besides, it is particularly pointed out that the reaction environment plays an essential role in the product distribution of the reaction; formate is generated with higher selectivities and activities in a highly alkaline environment than in a weak one.

Furthermore, identical location scanning electron microscopy (IL-SEM) is herein demonstrated as a powerful technique to study the structural degradation of the electrocatalysts. By imaging the same spot on the catalyst before and after the CO2RR, it is possible to directly visualize changes of the catalyst morphology on a nm-length scale attributed to the electrolysis reaction. Limitations of this analysis technique are discussed based on surfactant-protected nanocatalysts.

Additionally, a new electrochemical surfactant removal method based on potentiostatic CO2RR electrolysis was developed to remove polyvinylpyrrolidone or PVP (the capping agent) from Ag nanowire and nanocube surfaces, resulting in a substantially improved selectivity towards CO formation.

Overall, the studies presented herein clearly demonstrate the importance of performing CO2RR under more realistic conditions to bring this process closer to what is needed for the scale-up of this reaction, which means that high faradaic efficiencies, partial current densities, and long stability are pursued.

A consistent regularization procedure is proposed, which exploits the Poincaré invariance of the theory. Effective equation of motion of radiating charge in an external electromagnetic field is obtained via the consideration of energy-momentum and angular momentum conservation. This equation includes the effect of the particle's own field. The radiation reaction is determined by the Lorentz force of point-like charge acting upon itself plus a non-local term which provides finiteness of the self-action.

description: We have carried out a detailed experimental investigation of the static properties of planar Josephson tunnel junctions in presence of a uniform external magnetic field applied in an arbitrary orientation with respect to the barrier plane. We considered annular junctions, as well as rectangular junctions (having both overlap and cross-type geometries) with different barrier aspect ratios. It is shown how most of the experimental findings in an oblique field can be reproduced invoking the superposition principle to combine the classical behavior of electrically small junctions in an in-plane field together with the small junction behavior in a transverse field that we recently published [R. Monaco et al., J. Appl. Phys. vol 104, 023906 (2008)]. We explore the implications of these results in supposing systematic errors in previous experiments and in proposing new possible applications. We show that the presence of a transverse field may have important consequences, which could be either voluntarily exploited in applications or present an unwanted perturbation.

description: We give uniqueness theorem and reconstruction algorithm for the nonlinearized problem of finding the dielectric anisotropy f of the medium from non-overdetermined polarization tomography data. We assume that the medium has uniform background parameters and that the anisotropic (dielectric permeability) perturbation is described by symmetric and sufficiently small matrix-function f . On a pure mathematical level this article contributes to the theory of non-abelian Radon transforms and to iterative methods of inverse scattering.

description: This resource is a single blog post created as part of the Day of Archaeology initiative. The Day of Archaeology project aimed to provide a window into the daily lives of archaeologists from all over the world. The project asked people working, studying or volunteering in the archaeological world to participate in a 'Day of Archaeology' each year by recording their day and sharing it through text, images or video on the Day of Archaeology blog.
The project asked anyone with a personal, professional or voluntary interest in archaeology to get involved, and help highlight the reasons why archaeology is vital to protect the past and inform our futures. The resulting Day of Archaeology project archive demonstrates the wide variety of work the archaeological profession undertakes day-to-day across the globe, and helps to raise public awareness of the relevance and importance of archaeology to the modern world.
The first ever Day of Archaeology was held in 2011 and, since then, the project had thousands of archaeologists take part in the event, from those working in the field through to specialists working in laboratories and behind computers. The last Day of Archaeology was on Friday 28th July 2017.
O- and H- induced surface core level shifts on Ru(0001): Prevalence of the additivity rule

description: In previous work on adsorbate-induced surface core level shifts (SCLSs), the effects caused by O atom adsorption on Rh(111) and Ru(0001) were found to be additive: the measured shifts for first layer Ru atoms depended linearly on the number of directly coordinated O atoms. Density-functional theory calculations quantitatively reproduced this effect, allowed separation of initial and final state contributions, and provided an explanation in terms of a roughly constant charge transfer per O atom. We have now conducted similar measurements and calculations for three well-defined adsorbate and coadsorbate layers containing O and H atoms: (1 x 1)-H, (2 x 2)-(O+H), and (2 x 2)-(O+3H) on Ru(0001). As H is stabilized in fcc sites in the prior two structures and in hcp sites in the latter, this enables us to not only study coverage and coadsorption effects on the adsorbate-induced SCLSs, but also the sensitivity to similar adsorption sites. Remarkably good agreement is obtained between experiment and calculations for the energies and geometries of the layers, as well as for all aspects of the SCLS values. The additivity of the next-neighbor adsorbate-induced SCLSs is found to prevail even for the coadsorbate structures. While this confirms the suggested use of SCLSs as fingerprints of the adsorbate configuration, their sensitivity is further demonstrated by the slightly different shifts unambiguously determined for H adsorption in either fcc or hcp hollow sites.

QGP thermodynamics and meson spectroscopy with AdS/CFT

description: In this talk we present applications of the AdS/CFT correspondence to strongly coupled systems at finite temperature and particle density. The model we investigate contains adjoint matter described by the gauge multiplet of N=4, as well as fundamental matter given by the hypermultiplet of N=2 Super Yang-Mills theory. In some aspects these systems can be thought of as models for the quark-gluon plasma. In the first part we review some properties of meson spectra obtained from these holographic models. We discuss the implications of finite temperature and particle density in these string-theory motivated setups. In particular, we find a broadening of the vector meson peaks in the relevant spectral function at finite density. However, we do not observe a movement of the resonances to lower frequencies. Moreover, we analyze the effects of strong coupling on heavy meson diffusion in medium. To do so, we make use of an effective model with dipole interaction, which is valid for heavy quarks at arbitrary coupling strength. We calculate the momentum broadening -- normalized to the in-medium mass shift -- and compare the large 't Hooft coupling AdS/CFT result with a perturbative result for weak coupling. We find that the momentum broadening is reduced at large 't Hooft coupling, leading to increased relaxation time.
