description: This paper deals with the $(p,q)$--Schrödinger--Poisson system \begin{eqnarray*} \left \{\begin{array}{ll} \displaystyle -Δ_p u+|u|^{p-2}u+λϕ|u|^{s-2}u=|u|^{r-2}u,&\mathrm{in} \ \mathbb{R}^3,\\ \displaystyle -Δ_q ϕ= |u|^s, &\mathrm{in}\ \mathbb{R}^3,\\ \end{array} \right. \end{eqnarray*} where $10$ is a parameter. This quasilinear system is new and has never been considered in the literature. The uniqueness of solutions of the quasilinear Poisson equation is obtained via the Minty--Browder theorem. The variational framework of the quasilinear system is built and the nontrivial solutions of the system are obtained via the mountain pass theorem.

description: The Double Pulsar system PSR J0737-3039A/B has proven to be an excellent laboratory for high precision tests of general relativity. With additional years of timing measurements and new telescopes like the Square Kilometre Array (SKA), the precision of these tests will increase and new effects like the Lense-Thirring precession of the orbit will become measurable. Here, we discuss the prospects of measuring the Lense-Thirring effect and thereby constraining the equations of state at supra-nuclear densities in neutron stars using the Double Pulsar.

description: The surface rotation rates of young solar-type stars vary rapidly with age from the end of the pre-main sequence through the early main sequence. Important changes in the dynamos operating in these stars may result from this evolution, which should be observable in their surface magnetic fields. Here we present a study aimed at observing the evolution of these magnetic fields through this critical time period. We observed stars in open clusters and stellar associations of known ages, and used Zeeman Doppler Imaging to characterize their complex magnetic large-scale fields. Presented here are results for 15 stars, from 5 associations, with ages from 20 to 250 Myr, masses from 0.7 to 1.2 solar masses, and rotation periods from 0.4 to 6 days. We find complex large-scale magnetic field geometries, with global average strengths from 14 to 140 G. There is a clear trend towards decreasing average large-scale magnetic field strength with age, and a tight correlation between magnetic field strength and Rossby number. Comparing the magnetic properties of our zero-age main sequence sample to those of both younger and older stars, it appears that the magnetic evolution of solar-type stars during the pre-main sequence is primarily driven by structural changes, while it closely follows the stars' rotational evolution on the main sequence.

description: A key step during industrial design is the passing of design information from computer aided design (CAD) to analysis tools (CAE) and vice versa. Here, one is faced with a severe incompatibility in geometry representation: While CAD is usually based on surface representations, analysis mostly relies on volumetric representations. The forward pass, i.e., converting CAD data to computational meshes, is well understood and established. However, the same does not hold for the inverse direction, i.e., CAD reconstruction of deformed geometries resulting, e.g., from shape optimization. The few reconstruction methods reported mainly rely on spline fitting, in particular methods that rely on creating new splines simililar to shape reconstruction from 3D imaging. In contrast, this paper studies a novel approach that reuses the CAD data given in the initial design. We show that this concept leads to precise shape reconstructions while also preserving the initial notion of features defined during design. Furthermore, reusing the initial CAD representation reduces the shape reconstruction problem to a shape modification problem. We study this unique feature and show that it enables the reconstruction of CAD data from computational meshes by composing each spline in the initial CAD data with a single, global deformation spline. While post-processing is needed for use in current CAD software, this novel approach not only allows creating watertight models, but also enables reconstructing complete CAD models even from defeatured computational meshes.

ANDES, the high resolution spectrograph for the European Extremely Large Telescope

Publisher: name: Zenodo
Year: 2023

description: I will describe ANDES (ArmazoNes high Dispersion Echelle Spectrograph) the optical-infrared High Resolution Spectrograph of the ELT, formerly known as ELT-HIRES, which has started construction activities in 2022 to arrive at the telescope as early as 2031. The project is carried out by an international consortium composed of 33 institutes from 13 countries.
 The top science cases will be the detection of life signatures from exoplanet atmospheres, tests on the stability of Nature’s fundamental couplings, the direct detection of the cosmic acceleration, the characterization of astrophysical plasmas from the atmospheres of cool stars to the integalactic medium. Many of these science cases require that the instrument is capable of reaching challenging levels of precision and accuracy.
 I will present an overview of the project, describing science cases and the baseline design. The baseline design, which allows to fulfil the top science cases, consists of a modular fibre-fed cross-dispersed echelle spectrograph providing a simultaneous range of 0.4-1.8 µm with a goal of 0.35-2.4 µm, at a resolution of 100,000 and with several observing modes. The spectrograph will be equipped with both seeing- and diffraction-limited observing modes, the latter being characterised by a unique high resolution IFU, capable of a simultaneous wavelength coverage of 1-1.8 µm. Finally, I will conclude by discussing the challenges in spectral fidelity that ANDES will have to face.

description: The census of solar neighbours is still complemented by new discoveries, mainly of very low-mass, faint dwarfs, close to or within the substellar domain. These discoveries contribute to a better understanding of the field population; its origin in terms of Galactic dynamics and (sub)stellar formation and evolution. Also, the nearest stars and brown dwarfs at any given age allow the most precise direct characterization, including the search for planetary companions. We aim to further assess the substellar census on the Galactic plane. We projected the 136 stars and 26 brown dwarfs known at <6.5 pc on the Galactic plane and evaluated their distributions. Stars present a uniform- and brown dwarfs a non-uniform distribution, with 21 objects behind the Sun and only five ahead relative to the direction of rotation of the Galaxy. This substellar configuration has a probability of 0.098$^{+10.878}_{-0.098}$% relative to uniformity. The helio- and geocentric nature of the distribution suggests it might result in part from an observational bias, which if compensated for by future discoveries, might increase the brown-dwarf-to-star ratio, shifting it closer to values found in some star forming regions.

description: We suggest how to consistently calculate the anomalous dimension $γ_*$ of the $\barψψ$ operator in finite order perturbation theory at an infrared fixed point for asymptotically free theories. If the $n+1$ loop beta function and $n$ loop anomalous dimension are known then $γ_*$ can be calculated exactly and fully scheme independently through $O(Δ_f^n )$ where $Δ_f = \bar{N_f} - N_f$ and $N_f$ is the number of flavors and $\bar{N}_f$ is the number of flavors above which asymptotic freedom is lost. For a supersymmetric theory the calculation preserves supersymmetry order by order in $Δ_f$. We then compute $γ_*$ through $O(Δ_f^2)$ for supersymmetric QCD in the $\overline{\text{DR}}$ scheme and find that it matches the exact known result. We find that $γ_*$ is astonishingly well described in perturbation theory already at the few loops level throughout the entire conformal window. We finally compute $γ_*$ through $O(Δ_f^3)$ for QCD and a variety of other non-supersymmetric fermionic gauge theories. Small values of $γ_*$ are observed for a large range of flavors.

description: Isolated ideal neutron stars (NS) of age $>10^9$ yrs exhaust thermal and rotational energies and cool down to temperatures below $\mathcal{O}(100)$ K. Accretion of particle dark matter (DM) by such NS can heat them up through kinetic and annihilation processes. This increases the NS surface temperature to a maximum of $\sim 2550$ K in the best case scenario. The maximum accretion rate depends on the DM ambient density and velocity dispersion, and on the NS equation of state and their velocity distributions. Upon scanning over these variables, we find that the effective surface temperature varies at most by $\sim 40\%$. Black body spectrum of such warm NS peak at near infrared wavelengths with magnitudes in the range potentially detectable by the James Webb Space Telescope (JWST). Using the JWST exposure time calculator, we demonstrate that NS with surface temperatures $\gtrsim 2400$ K, located at a distance of 10\,pc can be detected through the F150W2 (F322W2) filters of the NIRCAM instrument at SNR\,$\gtrsim 10$ (5) within 24 hours of exposure time. Independently of DM, an observation of NS with surface temperatures $\gtrsim 2500$ K will be a formative step towards testing the minimal cooling paradigm during late evolutionary stages.

description: We propose to compute the effective activation energy, usually referred to a pseudopotential or quasipotential, of a birhythmic system -- a van der Pol like oscillator -- in the presence of correlated noise. It is demonstrated, with analytical techniques and numerical simulations, that the correlated noise can be taken into account and one can retrieve the low noise rate of the escapes. We thus conclude that a pseudopotential, or an effective activation energy, is a realistic description for the stability of birhythmic attractors also in the presence of correlated noise.

description: We develop a procedure to determine the portion of exact Hartree-Fock exchange interaction contained in a hybrid density functional to treat the range of electronic correlation governing the physics of a system as a function of a thermodynamical parameter. This includes systems that depend on physical parameters accessible to experiment (i.e., temperature, pressure, composition, etc.) or those composed of two or more materials such as heterostructures and interfaces. This approach is applied to LaMnO$_3$ where for the first time we are able to simulate the high temperature insulator-to-metal transition (IMT) and observe a half-metallic orbital disorder ferromagnetic state using density functional theory. In particular, we show that the softening of the \textit{Q$_2$} Jahn-Teller mode plays a central role in driving the IMT. These findings are likely to motivate the investigation of heterostructures and bulk materials that contain a range of electronic correlation in similar material systems.

description: Binary neural networks leverage $\mathrm{Sign}$ function to binarize weights and activations, which require gradient estimators to overcome its non-differentiability and will inevitably bring gradient errors during backpropagation. Although many hand-designed soft functions have been proposed as gradient estimators to better approximate gradients, their mechanism is not clear and there are still huge performance gaps between binary models and their full-precision counterparts. To address these issues and reduce gradient error, we propose to tackle network binarization as a binary classification problem and use a multi-layer perceptron (MLP) as the classifier in the forward pass and gradient estimator in the backward pass. Benefiting from the MLP's theoretical capability to fit any continuous function, it can be adaptively learned to binarize networks and backpropagate gradients without any prior knowledge of soft functions. From this perspective, we further empirically justify that even a simple linear function can outperform previous complex soft functions. Extensive experiments demonstrate that the proposed method yields surprising performance both in image classification and human pose estimation tasks. Specifically, we achieve $65.7\%$ top-1 accuracy of ResNet-34 on ImageNet dataset, with an absolute improvement of $2.6\%$. Moreover, we take binarization as a lightweighting approach for pose estimation models and propose well-designed binary pose estimation networks SBPN and BHRNet. When evaluating on the challenging Microsoft COCO keypoint dataset, the proposed method enables binary networks to achieve a mAP of up to $60.6$ for the first time. Experiments conducted on real platforms demonstrate that BNN achieves a better balance between performance and computational complexity, especially when computational resources are extremely low.

description: Many efforts to detect Earth-like planets around low-mass stars are currently devoted to almost every extra-solar planet search. M dwarfs stand as ideal targets for Doppler radial velocity searches as their low masses and luminosities make low-mass planets orbiting within their habitable zones more easily detectable than those around higher-mass stars. Nonetheless, the statistics of the frequency of this kind of planet hosted by low-mass stars remains poorly constrained. Our M-dwarf radial velocity monitoring with HARPS-N within the HARPS-N Red Dwarf Exoplanet Survey Radial Velocity (HADES) project started in 2012 and is contributing to the widening of the current statistics through the in-depth analysis of accurate radial velocity observations in a narrow range of spectral sub-types from M0 to M3, to investigate the planetary population around a well-defined class of host stars. The HADES project is the result of a collaborative effort between the Italian Global Architecture of Planetary Systems (GAPS) Consortium, the Institut de Ciències de l’Espai de Catalunya (ICE), and the Instituto de Astrofísica de Canarias (IAC).

Financial Fit and Academic Match for Chicago Public Schools’ College-Bound Seniors

Subjects: subject: College Match

description: Academic match is a well-documented phenomenon shown to be closely tied to postsecondary outcomes such as college graduation rates and earned income. This study explores the association between college net cost and academic match using student-level data of Chicago Public Schools seniors from the 2020-2021 school year. I find significant evidence of unique financial pressures placed on academically competitive, low-income students who are likely to receive relatively poor financial aid packages that could disincentivize them from attending a match college. This represents a new factor for consideration in studying patterns of academic match, and I argue how certain strategies in postsecondary advising and targeted funding could improve graduation rates among low-income competitive students.
Spectral Fidelity. Opportunities, limitations, and future challenges
Creators: name: Dravins, Dainis
Publisher: name: Zenodo
Year: 2023

description: Ambitions toward spectra with maximum truthfulness are constrained by optical physics of grating spectrometers. Spectral fidelity depends on calibrating for the blaze function; segregating overlapping orders; understanding scattered light, and polarization response. No high-resolution spectra in the optical have yet been recorded of any star (or the Sun) from outside the atmosphere: all data are contaminated by telluric absorption. Spectra with S/N = 1000 enable studies of the fine structure in interstellar absorption lines. S/N = 10,000 permits to study line shapes across stellar surfaces during exoplanet transit. S/N = 100,000 would reveal detailed line profiles from starspots temporarily covered by an exoplanet. Spectral resolutions approaching R = 1,000,000 fully resolve line asymmetries from stellar granulation and may be needed for absorption line profiles in quasars, shaped by convective motions in the intergalactic medium. CCD detectors need attention because of interference caused by their partial transparency and induced asymmetries in the direction of electronic readout. Future-generation detectors that enable photon counting and wavelength resolution include microwave kinetic inductance detectors, transition-edge sensors, and superconducting nanowires. A grand challenge remains in designing an efficient ELT spectrometer for R = 1,000,000 and S/N = 100,000. High-fidelity spectroscopy, combined with quantum optics, remains a challenge for ELT and beyond.

Year: 1999

description: The work presented for examination in this thesis concerns the investigation and management of patients with stroke. The underlying theme which unites the chapters is that of outcome following stroke, and how it may be influenced or predicted. Chapter one is a broad overview of stroke disease, incorporating a brief summary of the socio-economic burden of stroke in the Western world. Chapter two reports a randomised, double blind placebo-controlled study designed to investigate the effect of the angiotensin converting enzyme inhibitor perindopril upon cerebral and renal perfusion in hypertensive stroke patients with carotid artery disease. Chapter three reports a study to investigate the feasibility of rigorous control of blood glucose in hyperglycaemic patients following stroke. The prognostic significance of triglyceride concentration following ischaemic stroke is investigated in chapter four. In chapter five the prognostic significance of visible infarction on computed tomography in patients with lacunar stroke is examined. In chapter six the development and implementation of a novel diffusion- weighted magnetic resonance sequence is reported. In chapter seven, preliminary experience with the use of recombinant tissue plasminogen activator in a UK stroke centre is reported. Chapter eight contains a synopsis of the work presented, together with a brief discussion of the results in the context of our current understanding of stroke disease Future directions of study arising from the research are identified and discussed.

Hot gas and magnetic arms of NGC 6946: indications for reconnection heating?

description: The grand-design face-on spiral galaxy NGC6946 is remarkable because of its high star formation activity, the massive northern spiral arm, and the magnetic arms, which are observed in polarized radio synchrotron emission and are located between the optical arms and possibly are magnetic reconnection regions. X-ray observations of NGC6946 performed with XMM-Newton were used to study the emission from X-ray point sources and diffuse hot gas, including the magnetic arms and the halo. Spectral fitting of the diffuse X-ray emission allowed us to derive temperatures of the hot gas. With assumptions about the emission volume, this allowed us to estimate gas densities, masses, and cooling times. To explain the X-ray emission from the spiral arms of NGC6946 two-temperature plasma models are needed to account for the disk and halo emission. The interarm regions show only one thermal component. We observe that the temperature of the hot gas in and above the magnetic arm regions increases slightly when compared to the average temperatures in the areas in and above the spiral arms. For the southwestern part of the disk, which is depolarized in the radio range by Faraday rotation, we find more efficient mixing of disk and halo gas. We propose magnetic reconnection in the magnetic arm regions of NGC6946 as the possible cause of the additional heating of the gas and ordering of the magnetic fields. In the southwestern part of the galactic disk we observed indications of a possible faster outflow of the hot gas. A very hot gas within the MF16 nebula possibly suggests shock heating by a supernova explosion.

description: The standard definition of pedestrian density produces scattered values, hence, many approaches have been developed to improve the features of the estimated density. This paper provides a review of generally applied methods and presents a general framework based on various kernels that bring desired properties of density estimates (e.g., continuity) and incorporate ordinarily used methods. The developed kernel concept considers each pedestrian as a source of density distribution, parametrized by the kernel type (e.g., Gauss, cone) and kernel size. The quantitative parametric study performed on experimental data illustrates that parametrization brings desired features, for instance, a conic kernel with a base radius in (0.7, 1.2) m produces smooth values that retain trend features. The correspondence between kernel and non-kernel methods (namely Voronoi diagram and customized inverse distance to the nearest pedestrian) is achievable for a wide range of kernel parameter. Thereby the generality of the concept is supported.

description: We investigate single CoFeB nanotubes with hexagonal cross-section using dynamic cantilever magnetometry (DCM). We develop both an analytical model based on the Stoner-Wohlfarth approximation and a broadly applicable numerical framework for analyzing DCM measurements of magnetic nanostructures. Magnetometry data show the presence of a uniformly magnetized configuration at high external fields with $μ_0 M_s =1.3 \pm 0.1$ T and non-uniform configurations at low fields. In this low-field regime, comparison between numerical simulations and DCM measurements supports the existence of flux-closure configurations. Crucially, evidence of such configurations is only apparent because of the sensitivity of DCM to single nanotubes, whereas conventional measurements of ensembles are often obscured by sample-to-sample inhomogeneities in size, shape, and orientation

Atomic isotopic ratio measurements

description: Separating stars enriched in the s- and r-processes of nucleosynthesis is usually done by analysing element ratios of ”mainly s-process” elements (like Ba or La) to ”mainly r-process” elements (like Eu). The situation gets more complex when analysing CEMP-rs stars, which are Carbon-Enriched Metal-Poor objects enriched in a mixture of s- and r-elements. These objects, possibly resulting from the i-process of nucleosynthesis, are notoriously difficult to classify based on elemental ratio. Recent theoretical studies have outlined that the s-, i- and r-processes produce distinct isotopic mixtures. However, isotopic abundances are notoriously difficult to measure from atomic lines, because isotopic shifts of atomic lines are negligible compared to the line width. However, in contrast with the spectral lines of even isotopes, the lines of the odd isotopes are affected by hyperfine splitting (HFS). It is thus possible to measure the odd fraction of the isotopic mixture f(Ba,odd) and to relate it to a given nucleosynthetic process (either s-process, or i/r-processes). In this talk, some atomic isotopic diagnostics will be reviewed. Recent progress on how the isotopic mixture can constrain nucleosynthetic processes will be presented. The current limits on f(Ba,odd) determinations from high-resolution spectra will be addressed.

The power of the dark side: hunting spiders to find the most massive neutron stars
Creators: name: Simpson, Jordan

Publisher: name: Zenodo
Year: 2023

description: The maximum neutron star mass has profound impacts across a variety of fields. Gravitational wave astronomy, nuclear physics, and stellar astrophysics all depend on this critical value that is still poorly constrained. Compact binary millisecond pulsars, with rapidly-spinning neutron stars spun up by a sustained accretion phase, can harbour the most massive neutron stars, and their numbers are quickly growing.
 Using the largest ground-based telescopes and phase-resolved spectroscopy, we study these cannabilistic systems, also known as spiders, in which the pulsar ablates its companion with intense relativistic winds. This can produce strong irradiation effects that shift the companion's centre of light away from its centre of mass. The dark side of the companion is the key to obtaining a robust orbital solution.
 By using precise cross-correlation techniques on both the hydrogen lines that dominate the irradiated face, and the metallic line species of the dark side, we can accurately determine the true motion of the companion.
 Combining this with optimal subtraction techniques, we can follow the temperature variation of the companion throughout its orbit to obtain the orbital inclination. By taking advantage of the two sides of the companion and leveraging the different temperature-dependent line species, we can obtain the most precise neutron star mass measurements, and continue the hunt for the maximum neutron star mass.

description: We theoretically study the entropy production and the work extracted from a system connected to two reservoirs by periodic modulations of the electrochemical potentials of the reservoirs and the parameter of a system Hamiltonian under isothermal conditions. We find that the modulation of the parameters can drive a geometric state, which is away from a nonequilibrium steady state. Using this property, we construct a demon in which the entropy production during the first one-cycle is negative such that we can extract the work if we start from the nonequilibrium steady state without parameter modulations. We use the Anderson model to implement the demon in a realistic situation.

Search for new phenomena in final states with photons, jets and missing transverse momentum in $pp$ collisions at $\sqrt{s} = 13$ TeV with the ATLAS detector
Creators: name: ATLAS Collaboration
Publisher: name: arXiv
Year: 2022
Subjects: subject: High Energy Physics - Experiment (hep-ex)
subject: FOS: Physical sciences

description: A search for new phenomena has been performed in final states with at least one isolated high-momentum photon, jets and missing transverse momentum in proton--proton collisions at a centre-of-mass energy of $\sqrt{s} = 13$ TeV. The data, collected by the ATLAS experiment at the CERN LHC, correspond to an integrated luminosity of 139 $fb^{-1}$. The experimental results are interpreted in a supersymmetric model in which pair-produced gluinos decay into neutralinos, which in turn decay into a gravitino, at least one photon, and jets. No significant deviations from the predictions of the Standard Model are observed. Upper limits are set on the visible cross section due to physics beyond the Standard Model, and lower limits are set on the masses of the gluinos and neutralinos, all at 95% confidence level. Visible cross sections greater than 0.022 fb are excluded and pair-produced gluinos with masses up to 2200 GeV are excluded for most of the NLSP masses investigated.

title: Risk estimation and discontinuity identification in Bayesian disease mapping
Creators: name: Yin, Xueqing
Publisher: name: University of Glasgow
Year: 2022

description: Disease mapping is the field of epidemiology that estimates the spatial or spatio-temporal pattern in disease risk. Approaches in this field are generally based on data collected on a set of non-overlapping areal units that comprise the study region, and typically utilise counts of the numbers of disease cases within each areal unit. Conditional autoregressive (CAR) models are commonly used to capture the spatial autocorrelation present in areal unit disease count data. The spatial correlation structure that is induced by these models is typically determined by a neighbourhood matrix based on geographical adjacency, which enforces spatial correlation between geographically neighbouring areas and assumes a spatially smooth risk surface. However this may not be realistic in practice, because some pairs of neighbouring areas are likely to exhibit vastly different disease risks. Therefore the aim of this thesis is to develop methodology that allows for discontinuities in the spatial risk pattern when estimating disease risk. The first two models proposed are in a purely spatial setting and account for discontinuities by identifying spatial clusters of areas that have higher or lower risks than their geographical neighbours, while the third proposed model extends this to the spatio-temporal domain to identify clusters/discontinuities and estimate the spatial pattern of disease risk over time. The final piece of work of this thesis allows for discontinuities by using a boundary analysis approach. This approach identifies the boundaries in the spatial risk surface that separate pairs of geographically adjacent areas that exhibit large differences between their risks. Each model is applied to hospital admissions data for respiratory disease from the Greater Glasgow and Clyde Health Board region. Overall, it has been found that the respiratory disease risk surface in Greater Glasgow is not globally spatially smooth. There are numerous pairs of neighbouring areas where a discontinuity in disease risk appears to exist. In addition, the respiratory disease risk in Glasgow appears to increase over time and people living in more deprived areas are at higher risk of respiratory hospital admissions than those living in more affluent areas.

description: The generalized linear model (GLM) has been widely used in practice to model counts or other types of non-Gaussian data. This paper introduces a framework for feature selection in the GLM that can achieve robust false discovery rate (FDR) control. The main idea is to construct a mirror statistic based on data perturbation to measure the importance of each feature. FDR control is achieved by taking advantage of the mirror statistic’s property that its sampling distribution is (asymptotically) symmetric about zero for any null feature. In the moderate-dimensional setting, i.e.,, we construct the mirror statistic based on the maximum likelihood estimation. In the high-dimensional setting, i.e.,, we use the debiased Lasso to build the mirror statistic. The proposed methodology is scale-free as it only hinges on the symmetry of the mirror statistic, thus can be more robust in finite-sample cases compared to existing methods. Both simulation results and a real data application show that the proposed methods are capable of controlling the FDR and are often more powerful than existing methods including the Benjamini-Hochberg procedure and the knockoff filter.
