description: Near-ambient pressure XPS and STM experiments are performed to study the intercalation of oxygen and nitrogen at different partial gas pressures and different temperatures in the graphene/Ni/Ir(111) system of different morphologies. We performed detailed experiments on the investigation of the chemical state and topography of graphene, before and after gas intercalation, depending on the amount of pre-intercalated Ni in graphene/Ir(111). It is found that only oxygen can be intercalated under graphene in all considered cases, indicating the role of the intra-molecular bonding strength and possibility of gas molecules dissociation on different metallic surfaces on the principal possibility and on the mechanism of intercalation of different species under graphene.

description: Die vorliegende Arbeit umfasst umfangreiche Untersuchungen und Darstellungen zum Bemessungserddruck und zur Setzungsentwicklung bei integralen Brücken. Bei integralen Brückenbauwerken spielt die Interaktion zwischen Bauwerk und Baugrund eine bedeutende Rolle, da diverse Zwangsbeanspruchungen aus dem Brückenüberbau direkt über die Widerlager auf die angrenzende Hinterfüllung übertragen werden. Der in Deutschland angewandte Bemessungsansatz des Erddrucks für Widerlagerwände von VOGT wird validiert. Darüber hinaus wird auf Grundlage der eigenen Erkenntnisse aus numerischen Berechnungen und Messungen am Beispielprojekt ein vereinfachter Bemessungsansatz vorschlagen. Außerdem beinhaltet die Arbeit ausführliche numerische Untersuchungen zum zyklischen Erddruck auf Widerlagerwände sowie zum Setzungsverhalten der angrenzenden Hinterfüllung mit vier verschiedenen Stoffmodellen: Hardening-Soil, Hypoplastizität mit und ohne intergranulare Dehnung und Neohypoplastizität. Im Transfer-Forschungsprojekt (DFG-Projektnummer 397521181) konnten innerhalb des ersten Jahres bereits einige Erkenntnisse gewonnen werden. Es lassen sich die sog. Tageszyklen, die auf Temperaturunterschiede zwischen Tag und Nacht zurück zu führen sind, in den Erddruckmessungen gut erkennen.
description: Design earth pressure and development of settlement at integral abutment bridges:The present thesis comprises extensive investigations and presentations of the design earth pressure and the development of settlement at integral bridges. At integral abutment bridge structures, the interaction between the structure and the soil plays an important role, since various constrained loads from the bridge superstructure are rather transferred directly via the abutments to the adjacent backfill. The design approach of the earth pressure for abutment walls by VOGT used in Germany is validated. In addition, a simplified design approach is proposed based on findings from numerical calculations and measurements from a sample project. Besides this thesis contains detailed numerical investigations regarding cyclic earth pressure on abutment walls as well as the settlement behavior of the adjacent backfill using four different material models: Hardening-Soil, hypoplasticity with and without intergranular expansion and neohypoplasticity Some of the insights were already gained within the first year of the sample research project (DFG project number 397521181). The so-called daily cycles which can be traced back to temperature differences between day and night were already well perceived in soil pressure measurements.

description: In this age of Facebook, Instagram and Twitter, there is rapidly growing interest in understanding network-enabled opinion dynamics in large groups of autonomous agents. The phenomena of opinion polarization, the spread of propaganda and fake news, and the manipulation of sentiment are of interest to large numbers of organizations and people, some of whom are resource rich. Whether it is the more nefarious players such as foreign governments that are attempting to sway elections or large corporations that are trying to bend sentiment -- often quite surreptitiously, or it is more open and above board, like researchers that want to spread the news of some finding or some business interest that wants to make a large group of people aware of genuinely helpful innovations that they are marketing, what is at stake is often significant. In this paper we review many of the classical, and some of the new, social interaction models aimed at understanding opinion dynamics. While the first papers studying opinion dynamics appeared over 60 years ago, there is still a great deal of room for innovation and exploration. We believe that the political climate and the extraordinary (even unprecedented) events in the sphere of politics in the last few years will inspire new interest and new ideas. It is our aim to help those interested researchers understand what has already been explored in a significant portion of the field of opinion dynamics. We believe that in doing this, it will become clear that there is still much to be done.

description: Abstract: Background: patients with palliative needs often experience high symptom burden which causes suffering to themselves and their families. Depression and psychological distress should not be considered a “normal event” in advanced disease patients and should be screened, diagnosed, acted on and followed-up. Psychological distress has been associated with greater physical symptom severity, suffering, and mortality in cancer patients. A holistic, but short measure should be used for physical and non-physical needs assessment. The Integrated Palliative care Outcome Scale is one such measure. This work aims to determine palliative needs of patients and explore screening accuracy of two items pertaining to psychological needs. Methods: multi-centred observational study using convenience sampling. Data were collected in 9 Portuguese centres. Inclusion criteria: ≥18 years, mentally fit to give consent, diagnosed with an incurable, potentially life-threatening illness. Exclusion criteria: patient in distress (“unable to converse for a period of time”), cognitively impaired. Descriptive statistics used for demographics. Receiving Operator Characteristics curves and Area Under the Curve for anxiety and depression discriminant properties against the Hospital Anxiety and Depression Scale. Results: 1703 individuals were screened between July 1st, 2015 and February 2016. A total of 135 (7.9%) were included. Main reason for exclusion was being healthy (75.2%). The primary care centre screened most individuals, as they have the highest rates of daily patients and the majority are healthy. Mean age is 66.8 years (SD 12.7), 58 (43%) are female. Most patients had a cancer diagnosis 109 (80.7%). Items scoring highest (=4) were: family or friends anxious or worried (36.3%); feeling anxious or worried about illness (13.3%); feeling depressed (9.6%). Using a cut-off score of 2/3, Area Under the Curve for depression and anxiety items were above 70%. Conclusions: main palliative needs were psychological, family related and spiritual. This suggests that clinical teams may better manage physical issues and there is room for improvement regarding non-physical needs. Using the Integrated Palliative care Outcome Scale systematically could aid clinical teams screening patients for distressing needs and track their progress in assisting patients and families with those issues.

description: This paper introduces a novel framework for dynamic classification in high dimensional spaces, addressing the evolving nature of class distributions over time or other index variables. Traditional discriminant analysis techniques are adapted to learn dynamic decision rules with respect to the index variable. In particular, we propose and study a new supervised dimension reduction method employing kernel smoothing to identify the optimal subspace, and provide a comprehensive examination of this approach for both linear discriminant analysis and quadratic discriminant analysis. We illustrate the effectiveness of the proposed methods through numerical simulations and real data examples. The results show considerable improvements in classification accuracy and computational efficiency. This work contributes to the field by offering a robust and adaptive solution to the challenges of scalability and non-staticity in high-dimensional data classification.

description: In recent years, there are research findings of haze formation in various fields of academic circle. It has proved that causes of haze take on diverse characteristics. Thus, from both the natural and human perspective, haze governance should be diverse. Research conclusions on causes of haze formation mainly focus on special geographical structure, and meteorological factors such as relatively stable atmosphere, high rate of calm wind, high relative humidity and temperature of air, and human factors such as industrial pollution, automotive exhaust emissions, aerosol pollution, eutrophication of soil water, and change of city underlying surface. Carbon sink mode is a new channel for haze governance. In carbon sink mode, it is feasible to regulate relative humidity and temperature in air, enhance global wind, and reduce fine particles and microorganisms of air pollution, so as to reduce haze pollution. Besides, China’s special potential of carbon sink market makes it possible to govern haze on the base of carbon sink.

WAVEFRONT SENSING

description: Earth observation from space has greatly benefited from advancements in angular resolution, which are essential for obtaining valuable scientific insights. Achieving high angular resolution relies on large telescope apertures. Recently, space telescopes have been designed to exceed the size limitations of the platform and rocket fairing, necessitating segmented pupils. This approach has proven successful for space telescopes (e.g., JWST) but also for large ground-based telescopes (e.g., Keck, ELT). Interestingly, such segmented pupils can also be implemented in small-volume platforms, such as CubeSats, which offer the advantage of reduced payload weight and launch costs, enabling higher revisit rates with satellite constellations. In our work, we present a novel implementation of a segmented telescope within a CubeSat. While segmented pupils allow for a relatively large aperture, they present a significant challenge in terms of achieving perfect alignment between the independent mirror petals. This alignment is crucial for realising the full angular resolution potential promised by a large aperture. However, the limited computation power and impossibility of having additional optics or dedicated wavefront sensors forces us to perform the wavefront sensing solely on a single focal plane image, requiring the use of more complex methods than classic ones. One of the main challenges of focal plane wavefront sensing is the non-linear relationship between phase and image intensity. Therefore, we leverage deep learning algorithms to address this problem directly. By utilising the spatial information from each pixel, convolutional neural networks algorithms excel at solving non-linear problems. Moreover, the computational burden is alleviated through off-line training steps, enabling efficient on-board computations. In this work, we focus on the identification of segmented pupil piston and tip-tilt phase coefficients from a single focal plane image of a point source. Our deep learning-based method successfully extracts the first three Zernike coefficients for each of the four petals, even in the presence of noise, higher-order aberrations, and stronger aberrations arising from the initial deployment. We demonstrate diffraction limit results in visible wavelength (about 15nm at 800nm) for relatively small NN architectures compared to the state-of-the-art ones. We then propose the application of our method to explore the phasing of larger space telescopes with more degrees of freedom, such as JWST with 18 segments. Finally, we extrapolate the potential application of our method to ground-based telescopes.
Pseudo-Schwarzschild description of transonic spherical accretion onto compact objects

Year: 2002

description: A number of `modified' Newtonian potentials of various forms are available in the literature which accurately approximate some general relativistic effects important for studying accretion discs around a Schwarzschild black hole. Such potentials may be called `pseudo-Schwarzschild' potentials because they nicely mimic the space-time around a non-rotating/slowly rotating compact object. In this paper, we examine the validity of the application of some of these potentials to study the spherically symmetric, transonic, hydrodynamic accretion onto a Schwarzschild black hole. By comparing the values of various dynamical and thermodynamic accretion parameters obtained for flows using these potentials with full general relativistic calculations, we have shown that though the potentials discussed in this paper were originally proposed to mimic the relativistic effects manifested in disc accretion, it is quite reasonable to use most of the potentials in studying various dynamical as well as thermodynamic quantities for spherical accretion to compromise between the ease of handling of a Newtonian description of gravity and the realistic situations described by complicated general relativistic calculations. Also we have shown that depending on the chosen regions of parameter space spanned by specific energy ${\cal E}$ and adiabatic index $γ$ of the flow, one potential may have more importance than another and we could identify which potential is the best approximation for full general relativistic flow in Scwarzschild space-time for particular values of ${\cal E}$ and $γ$.

description: We study the surface critical behavior of semi-infinite quenched random Ising-like systems at the special transition using three dimensional massive field theory up to the two-loop approximation. Besides, we extend up to the next-to leading order, the previous first-order results of the $\sqrtε$ expansion obtained by Ohno and Okabe [Phys. Rev. B 46, 5917 (1992)]. The numerical estimates for surface critical exponents in both cases are computed by means of the Pade analysis. Moreover, in the case of the massive field theory we perform Pade-Borel resummation of the resulting two-loop series expansions for surface critical exponents. The obtained results confirm that in a system with quenched bulk randomness the plane boundary is characterized by a new set of surface critical exponents.

description: What if the main data protection vulnerability is risk management? Data Protection merges three disciplines: data protection law, information security, and risk management. Nonetheless, very little research has been made on the field of data protection risk management, where subjectivity and superficiality are the dominant state of the art. Since the GDPR tells you what to do, but not how to do it, the solution for approaching GDPR compliance is still a gray zone, where the trend is using the rule of thumb. Considering that the most important goal of risk management is to reduce uncertainty in order to take informed decisions, risk management for the protection of the rights and freedoms of the data subjects cannot be disconnected from the impact materialization that data controllers and processors need to assess. This paper proposes a quantitative approach to data protection risk-based compliance from a data controllers perspective, with the aim of proposing a mindset change, where data protection impact assessments can be improved by using data protection analytics, quantitative risk analysis, and calibrating expert opinions.

description: Abstract: Previous studies have reported positive correlations between autistic traits and disordered eating, though it is unclear whether the association is moderated by sex/gender or whether it is independent of anxiety or depression. We present the findings of an online survey of 691 participants who completed the Autism Spectrum Quotient (AQ), Hospital Anxiety and Depression Scale (HADS), and Eating Attitudes Test-26 (EAT-26). Following a pre-registered analysis plan, we observed positive correlations between AQ and EAT-26 in males and females, with the association being significantly stronger in females. AQ also remained a significant predictor of EAT-26 when anxiety and depression were controlled for statistically. These findings may be relevant when considering therapeutic interventions in disordered eating populations that exhibit autistic traits.

description: In this paper we discuss a formulation of extended phase space thermodynamics of black holes in Anti de Sitter (AdS) spacetimes from the contact geometry point of view. Thermodynamics of black holes can be understood within the framework of contact geometry as flows of vector fields generated by Hamiltonian functions on equilibrium submanifolds in the extended phase space that naturally incorporates the structure of a contact manifold. Deformations induced by the contact vector fields are used to construct various maps among thermodynamic quantities. Thermodynamic variables and equations of state of Schwarzschild black holes are mapped to that of Reissner-Nordström black holes in AdS, with charge as the deformation parameter. In addition, the equations of state of general black holes in AdS are shown to emerge from the high-temperature ideal gas limit equations via suitable deformations induced by contact vector fields. The Hamilton-Jacobi formalism analogous to mechanics is set up, and the corresponding characteristic curves of contact vector fields are explicitly obtained to model thermodynamic processes of black holes. Extension to thermodynamic cycles in this framework is also discussed.

description: We study the ballistic edge-channel transport in quantum wires with a magnetic quantum dot, which is formed by two different magnetic fields B^* and B_0 inside and outside the dot, respectively. We find that the electron states located near the dot and the scattering of edge channels by the dot strongly depend on whether B^* is parallel or antiparallel to B_0. For parallel fields, two-terminal conductance as a function of channel energy is quantized except for resonances, while, for antiparallel fields, it is not quantized and all channels can be completely reflected in some energy ranges. All these features are attributed to the characteristic magnetic confinements caused by nonuniform fields.

description: Axion Like Particles (ALPs) are one promising kind of dark matter candidate particles that are predicted to couple with photons in the presence of magnetic fields. The oscillations between photons and ALPs travelling in the magnetic fields have been used to constrain ALP properties. In this work, we obtain some new constraints on the ALP mass $m_{\rm a}$ and the photon-ALP coupling constant $g$ with two different magnetic field models through TeV photons from PKS 2155-304. One is the discrete-$φ$ model that the magnetic field has the orientation angle $φ$ changes discretely and randomly from one coherent domain to the next, another is the linearly-continuous-$φ$ model that the magnetic field orientation angle $φ$ varies continuously across neighboring coherent domains. For the discrete-$φ$ model, we can obtain the best constraints on the ALP mass $m_{1}=m_{\rm a}/(1\ {\rm neV})=0.1$ and on the photon-ALP coupling constant $g_{11}=g/(10^{-11}\ {\rm GeV^{-1}})=5$, the reasonable range of the ALP mass $m_{1}$ is 0.08 $\thicksim$ 0.2 when $g_{11}$=5, and the only reasonable value of the photon-ALP coupling constant is $g_{11}$=5 when $m_{1}$=0.1. For the linearly-continuous-$φ$ model, we can obtain the best constraints on the ALP mass $m_{1}=0.1$ and on the photon-ALP coupling constant $g_{11}=0.7$, the reasonable range of the ALP mass $m_{1}$ is 0.05 $\thicksim$ 0.4 when $g_{11}$=0.7, and the reasonable range of the photon-ALP coupling constant $g_{11}$ is 0.5 $\thicksim$ 1 when $m_{1}$=0.1. All the results are consistent with the upper bound ($g<6.6\times10^{-11}\ {\rm GeV^{-1}}$, i.e. $g_{11}<6.6$) set by the CAST experiment.

description: Optical conductivity data s(w) of the colossal magneto-resistance (CMR) pyrochlore Tl2Mn2O7 are presented as functions of temperature (T) and externalmagnetic field (B). Upon cooling and upon applying B near the Curietemperature, where the CMR manifests itself, s(w) shows a clear transition from an insulatorlike to a metallic electronic structure as evidenced by theemergence of a pronounced Drude-like component below 0.2 eV. Analyses on thes(w) spectra show that both T- and B-induced evolutions of the electronicstructure are very similar to each other, and that they are universally related to the development of macroscopic magnetization (M). In particular, the effective carrier density obtained from s(w) scales with M^2 over wide ranges of T and B. The contributions to the CMR from the carrier effective mass and scattering time are also evaluated from the data.

description: We evaluate the reliability of two chatbots, ChatGPT (4o and o1-preview versions), and Gemini Advanced, in providing references on financial literature and employing novel methodologies. Alongside the conventional binary approach commonly used in the literature, we developed a nonbinary approach and a recency measure to assess how hallucination rates vary with how recent a topic is. After analyzing 150 citations, ChatGPT-4o had a hallucination rate of 20.0% (95% CI, 13.6%-26.4%), while the o1-preview had a hallucination rate of 21.3% (95% CI, 14.8%-27.9%). In contrast, Gemini Advanced exhibited higher hallucination rates: 76.7% (95% CI, 69.9%-83.4%). While hallucination rates increased for more recent topics, this trend was not statistically significant for Gemini Advanced. These findings emphasize the importance of verifying chatbot-provided references, particularly in rapidly evolving fields.

description: The 2013 antidumping investigation suspension agreement introduced new categories of tomatoes and raised reference prices of Mexican field-grown and greenhouse tomatoes by 43% and 89%. We analyze the substitution and complementary relationships among different categories of tomatoes grown in the United States, Mexico, and other countries and measure substitution and income effects of reference price increases. Findings indicate that the new agreement may decrease demand for U.S. field-grown tomatoes in favor of Mexican field-grown and Mexican greenhouse tomatoes. Policies to increase overall U.S. tomato expenditures may be more favorable for U.S. tomato producers than the new reference prices.

description: Observations of AGNs and microquasars by ASCA, RXTE, Chandra and XMM-Newton indicate the existence of wide X-ray emission lines of heavy ionized elements in their spectra. The emission can arise in the inner parts of accretion discs where the effects of General Relativity (GR) must be counted, moreover such effects can dominate. We describe a procedure to estimate an upper limit of the magnetic fields in the regions where X-ray photons are emitted. We simulate typical profiles of the iron $K_α$ line in the presence of a magnetic field and compare them with observational data. As an illustration we find $H < 10^{10} - 10^{11}$ Gs for Seyfert galaxy MCG--6--30--15. Using the perspective facilities of measurement devices (e.g. Constellation-X mission) a better resolution of the blue peak structure of iron $K_α$ line will allow to find the value of the magnetic fields if the latter are high enough.

description: GMagAO-X is a visible to NIR extreme adaptive optics (ExAO) system that will be used at first light for the Giant Magellan Telescope (GMT). GMagAO-X is designed to deliver diffraction-limited performance at visible and NIR wavelengths (6 to 10 mas) and contrasts on the order of 10^-7. The primary science case of GMagAO-X will be the characterization of mature, and potentially habitable, exoplanets in reflected light. GMagAO-X employs a woofer-tweeter system and includes segment phasing control. The tweeter is a 21,000 actuator segmented deformable mirror (DM), composed of seven individual 3,000 actuator DMs. This new ExAO framework of seven DMs working in parallel to produce a 21,000 actuator DM significantly surpasses any current or near future actuator count for a monolithic DM architecture. Bootstrapping, phasing, and high order sensing are enabled by a multi-stage wavefront sensing system. GMT\'s unprecedented 25.4 m aperture composed of seven segments brings a new challenge of co-phasing massive mirrors to 1/100th of a wavelength. The primary mirror segments of the GMT are separated by large 30 cm gaps so there will be fluctuations in optical path length (piston) across the pupil due to vibration of the segments, atmospheric conditions, etc. We have developed the High Contrast Adaptive-optics Testbed (HCAT) to test new wavefront sensing and control approaches for GMT and GMagAO-X, such as the holographic dispersed fringe sensor (HDFS), and the new ExAO parallel DM concept for correcting aberrations across a segmented pupil. The CoDR for GMagAO-X was held in September 2021 and a preliminary design review is planned for early 2024. In this paper we will discuss the science cases and requirements for the overall architecture of GMagAO-X, as well as the current efforts to prototype the novel hardware components and new wavefront sensing and control concepts for GMagAO-X on HCAT.

description: The hypothesis of the quark Reggeization is tested by taking the high-energy limit of the two-loop amplitude for quark-gluon scattering which was recently calculated. The limit is compatible with the Reggeization in the leading and the next-to-leading orders and allows the determination of the quark trajectory in the two-loop approximation. The trajectory is presented as an expansion in powers of (D-4) for the space-time dimension $D$ tending to the physical value D=4.

description: We reanalyse the anisotropic galaxy clustering measurement from the Baryon Oscillation Spectroscopic Survey (BOSS), demonstrating that using the full shape information provides cosmological constraints that are comparable to other low-redshift probes. We find $Ω_\mathrm{m} = 0.317^{+0.015}_{-0.019}$, $σ_8 = 0.710\pm 0.049$, and $h = 0.704\pm 0.024$ for flat $Λ$CDM cosmologies using uninformative priors on $Ω_\mathrm{c}h^2$, $100θ_\mathrm{MC}$, $\ln 10^{10} A_{s}$, and $n_{s}$, and a prior on $Ω_\mathrm{b}h^2$ that is much wider than current constraints. We quantify the agreement between the Planck 2018 constraints from the cosmic microwave background and BOSS, finding the two data sets to be consistent within a flat $Λ$CDM cosmology using the Bayes factor as well as the prior-insensitive suspiciousness statistic. Combining two low-redshift probes, we jointly analyse the clustering of BOSS galaxies with weak lensing measurements from the Kilo-Degree Survey (KV450). The combination of BOSS and KV450 improves the measurement by up to 45%, constraining $σ_8 = 0.702\pm 0.029$ and $S_8 = σ_8\sqrt{Ω_\mathrm{m}/0.3} = 0.728\pm 0.026$. Over the full 5D parameter space, the odds in favour of single cosmology describing galaxy clustering, lensing, and the cosmic microwave background are $7\pm2$. The suspiciousness statistic signals a $2.1\pm0.3σ$ tension between the combined low-redshift probes and measurements from the cosmic microwave background.

description: We present IRAM/NOEMA, JCMT/SCUBA-2 and VLA observations of the most distant known gravitationally lensed quasar J0439+1634 at z = 6.5. We detect strong dust emission, [CII] 158 $μ$m, [CI] 369 $μ$m, [OI] 146 $μ$m, CO(6-5), CO(7-6), CO(9-8), CO(10-9), H$_{\rm 2}$O $3_{\rm 1,2}-2_{\rm 2,1}$, and H$_{\rm 2}$O $3_{\rm 2,1}-3_{\rm 1,2}$ lines as well as a weak radio continuum. The strong [CII] line yields a systemic redshift of the host galaxy to be z=6.5188$\pm$0.0001. The magnification makes J0439+1634 the far-infrared (FIR) brightest quasar at z > 6 known, with the brightest [CII] line yet detected at this redshift. The FIR luminosity is (3.4$\pm$0.2)$\times$10$^{13}$ $μ^{-1}$ $L_{\odot}$, where $μ$ $\sim$ 2.6 - 6.6 is the magnification of the host galaxy, estimated based on the lensing configuration from HST imaging. We estimate the dust mass to be (2.2$\pm$0.1)$\times$10$^{9}$ $μ^{-1}$ $M_{\odot}$. The CO Spectral Line Energy Distribution using four CO lines is best fit by a two-component model of the molecular gas excitation. The estimates of molecular gas mass derived from CO lines and atomic carbon mass are consistent, in the range of 3.9 - 8.9 $\times$10$^{10} μ^{-1}$ $M_{\odot}$. The [CII]/[CI], [CII]/CO, and [OI]/[CII] line luminosity ratios suggest a photodissociation region model with more than one component. The ratio of H$_{\rm 2}$O $3_{\rm 2,1}-3_{\rm 1,2}$ line luminosity to $L_{\rm TIR}$ is consistent with values in local and high redshift ultra-/hyper-luminous infrared galaxies. The VLA observations reveal an unresolved radio continuum source, and indicate that J0439+1634 is a radio quiet quasar with R = 0.05 - 0.17.
