description: The Engels polarization method, invented in September 2022 by Dr. R. Engels,offers an easy and reliable way to produce hyperpolarization in particle beams, e.g.,hydrogen, deuterium, $^3$He$^+$, etc.. This method draws inspiration from the Sonamethod proposed by P. G. Sona in 1967. It consists of two opposing magnetic fieldsto alter the total angular projection of pure states in hydrogen-like atoms. In thecase of the Engels method, the longitudinal magnetic field forms a sinusoidal, whichprovides a quantization axis and a zero crossing for the spin. Generating this fieldrequires two solenoids with mirrored currents, which must be placed in front ofeach other. Ramping their magnetic field leads to oscillations in the photomultipliersignal. These oscillations correlate to a change in the occupation numbers of theZeeman states and have been the subject of investigation at the Institute for NuclearPhysics (IKP) at the Research Center Jülich (FZJ) for the past few years. Theyare caused by transitions between the hyperfine sub-states related to the radialmagnetic field oscillations of the unit. This magnetic field component is proportionalto the radial distance from the symmetry axis of the coils and the derivative ofthe longitudinal component. In order to study the effects of this orthogonal fieldcomponent, a new transition device has been proposed. The new device needs tohave a proper sinusoidal waveform, so two coil pairs with opposite currents will beused. The offset for each coil to the beam pipe, as well as the relative distancebetween the coil pairs, can be changed in the new device. Details regarding thedevice’s operation and the methods for constructing a transverse transition unit areprovided in this thesis, along with simulated data to approximate its behavior.

description: In the fuzzball paradigm the information paradox is resolved because the black hole is replaced by an object with no horizon. One may therefore ask if observations can distinguish a traditional hole from a fuzzball. We find: (a) It is very difficult to reflect quanta off the surface of a fuzzball, mainly because geodesics starting near the horizon radius cannot escape to infinity unless their starting direction is very close to radial. (b) If infalling particles interact with the emerging radiation before they are engulfed by the horizon, then we say that we have a `firewall behavior'. We consider several types of interactions, but find no evidence for firewall behavior in any theory that obeys causality. (c) Photons with wavelengths {\it larger} than the black hole radius can be scattered off the emerging radiation, but a very small fraction of the backscattered photons will be able to escape back to infinity.

Quantification of ergodicity in stochastic homogenization: Optimal bounds via spectral gap on Glauber dynamics

description: We study quantitatively the effective large-scale behavior of discrete elliptic equations on the lattice Zd with random coefficients. The theory of stochastic homogenization relates the random, stationary, and ergodic field of coefficients with a deterministic matrix of effective coefficients. This is done via the corrector problem, which can be viewed as a highly degenerate elliptic equation on the infinite-dimensional space of admissible coefficient fields. In this contribution we develop new quantitative methods for the corrector problem based on the assumption that ergodicity holds in the quantitative form of a Spectral Gap Estimate w. r. t. a Glauber dynamics on coefficient fields - as it is the case for independent and identically distributed coefficients. As a main result we prove an optimal decay in time of the semigroup associated with the corrector problem (i. e. of the generator of the process called "random environment as seen from the particle"). As a corollary we recover existence of stationary correctors (in dimensions d > 2) and prove new optimal estimates for regularized versions of the corrector (in dimensions d >= 2). We also give a self-contained proof of a new estimate on the gradient of the parabolic, variable-coefficient Green's function, which is a crucial analytic ingredient in our approach. As an application of these results, we prove the first (and optimal) estimates for the approximation of the homogenized coefficients by the popular periodization method in case of independent and identically distributed coefficients.

description: ABSTRACT: Alcohol and Other Drug Facilitated Sexual Violence (AODFSV), known as “drink-spiking,” is the administration of alcohol or other drugs to someone without their consent, with the intent to harm them. Investigation into portrayals of AODFSV in the Australian news media is needed. Using feminist critical discourse analysis, this paper investigated the portrayal of AODFSV in the Australian news media in the past ten years. 226 articles were included for analysis and three themes were identified. Firstly, “how the media constructs the drink spiking narrative,” uses the “cautionary tale” that warns women about the dangers of the night-time economy and reinforces and perpetuates victim-blaming and rape myths. Secondly, “how the media normalises the drink spiking discourse” focuses on the substances used in drink spiking, the settings, the construction of the perpetrator and the victim as well as the depictions of sexual violence. Thirdly, “how the media shapes responses from emergency services” including police and hospital staff. This paper highlights the way the media creates and reinforces drinkspiking discourse, which constructs drink-spiking as individual behaviour rather than a culturally embedded issue. Such ideology perpetuates victim blaming and rape my

description: We present an implementation of a recently developed noise reduction algorithm for dMRI data, called multi-shell position orientation adaptive smoothing (msPOAS), as a toolbox for SPM. The method intrinsically adapts to the structures of different size and shape in dMRI and hence avoids blurring typically observed in non-adaptive smoothing. We give examples for the usage of the toolbox and explain the determination of experiment-dependent parameters for an optimal performance of msPOAS.

description: We present results of a simulation study regarding the finite-sample type I error behavior of the self-concordant profile empirical likelihood ratio (ELR) test for the population correlation coefficient. Three different families of bivariate elliptical distributions are taken into account. Uniformly over all considered models and parameter configurations, the self-concordant profile ELR test does not keep the significance level for finite sample sizes, albeit the level exceedance monotonously decreases to zero as the sample size increases. We discuss some potential modifications to address this problem.

description: There is mounting experimental evidence that brain-state specific neural mechanisms supported by connectomic architectures serve to combine past and contextual knowledge with current, incoming flow of evidence (e.g. from sensory systems). Such mechanisms are distributed across multiple spatial and temporal scales and require dedicated support at the levels of individual neurons and synapses. A prominent feature in the neocortex is the structure of large, deep pyramidal neurons which show a peculiar separation between an apical dendritic compartment and a basal dentritic/peri-somatic compartment, with distinctive patterns of incoming connections and brain-state specific activation mechanisms, namely apical-amplification, -isolation and -drive associated to the wakefulness, deeper NREM sleep stages and REM sleep. The cognitive roles of apical mechanisms have been demonstrated in behaving animals. In contrast, classical models of learning spiking networks are based on single compartment neurons that miss the description of mechanisms to combine apical and basal/somatic information. This work aims to provide the computational community with a two-compartment spiking neuron model which includes features that are essential for supporting brain-state specific learning and with a piece-wise linear transfer function (ThetaPlanes) at highest abstraction level to be used in large scale bio-inspired artificial intelligence systems. A machine learning algorithm, constrained by a set of fitness functions, selected the parameters defining neurons expressing the desired apical mechanisms.

TeV Gamma Rays Expected from Supernova Remnants in Different Uniform Interstellar Media

Subjects: subject: Astrophysics (astro-ph)

description: Calculations of the expected TeV $γ$-ray emission, produced by accelerated cosmic rays (CRs) in nuclear collisions, from supernova remnants evolving in a uniform interstellar medium (ISM) are presented. The aim is to study the sensitivity of $γ$-ray production to a physical parameter set. Apart from its general proportionality to N_H, it is shown that the $γ$-ray production essentially depends upon the ratio of the CR diffusion coefficient $κ$ to a critical value $κ_{crit}=10(B_0/5 μ{G})(N_H/0.3 {cm}^{-3})^{-1/3}κ_B$, where B_0 and N_H are the magnetic field and hydrogen number density of the ISM, and $κ_B$ denotes the Bohm diffusion coefficient. If $κ$ is of the same order or lower than $κ_{crit}$, then the peak TeV $γ$-ray flux in the Sedov evolutionary phase, normalized to a distance of 1 kpc, is about 10^{-10}(N_H/0.3 {cm}^{-3}) photons cm^{-2} s^{-1}. For a CR diffusion coefficient that is significantly larger than $κ_{crit}$, the CR cutoff energy is less than 10 TeV and the expected $γ$-ray flux at 1 TeV is considerably below the presently detectable level of 10^{-12} photons cm^{-2} s^{-1}. The same is of course true for a SNR in the rarified, so-called hot ISM.

description: We conducted a polarimetric observation of the fast-rotating near-Earth asteroid (1566) Icarus at large phase (Sun-asteroid-observer's) angles $α$= 57 deg--141deg around the 2015 summer solstice. We found that the maximum values of the linear polarization degree are $P_\mathrm{max}$=7.32$\pm$0.25 % at phase angles of $α_\mathrm{max}$=124$\pm$8 deg in the $V$-band and $P_\mathrm{max}$=7.04$\pm$0.21 % at $α_\mathrm{max}$=124$\pm$6 deg in the $R_\mathrm{C}$-band. Applying the polarimetric slope-albedo empirical law, we derived a geometric albedo of $p_\mathrm{V}$=0.25$\pm$0.02, which is in agreement with that of Q-type taxonomic asteroids. $α_\mathrm{max}$ is unambiguously larger than that of Mercury, the Moon, and another near-Earth S-type asteroid (4179) Toutatis but consistent with laboratory samples with hundreds of microns in size. The combination of the maximum polarization degree and the geometric albedo is in accordance with terrestrial rocks with a diameter of several hundreds of micrometers. The photometric function indicates a large macroscopic roughness. We hypothesize that the unique environment (i.e., the small perihelion distance $q$=0.187 au and a short rotational period of $T_\mathrm{rot}$=2.27 hours) may be attributed to the paucity of small grains on the surface, as indicated on (3200) Phaethon.

description: A probabilistic model for the Wigner equation is studied. The model is based on a particle system with the time evolution of a piecewise deterministic Markov process. Each particle is characterized by a real-valued weight, a position and a wave-vector. The particle position changes continuously, according to the velocity determined by the wave-vector. New particles are created randomly and added to the system. The main result is that appropriate functionals of the process satisfy a weak form of the Wigner equation.

description: Nonlinear polaritons in microcavity waveguides are demonstrated to exhibit multi-stable behaviour and rich dynamics, including filamentation and soliton formation. We find that the multi-stability originates from co-existense of different transverse modes of the po- laritonic waveguide. Modulational stability and conditions for multi-mode polariton solitons are studied. Soliton propagation in tilted, relative to the pump momentum, waveguides is demonstrated and a critical tilt angle for the soliton propagation is found.

description: This paper proposes k-medoids clustering method to reveal the distinct groups of 1,318 variable stars in the Galaxy based on their light curves, where each light curve represents the graph of brightness of the star against time. To overcome the deficiencies of subjective traditional classification, we separate the stars more scientifically according to their geometrical configuration and show that our approach outperforms the existing classification schemes in astronomy. It results in two optimum groups of eclipsing binaries corresponding to bright, massive systems and fainter, less massive systems.

description: Chestnut trees have been cultivated for centuries in Europe. The mountainous countries of the south are traditionally the largest producers of chestnuts in Europe. Although remaining a marginal crop, several chestnut industries have recently developed successfully in less rugged areas. Chestnuts are economically important species. The European chestnut (Castanea sativa) is native to southern Europe, Asia and North Africa. Its large crown can reach a height of 30 m and more over its 250 to 500 years. The Japanese chestnut (C. crenata) is a tree that has been introduced to Europe because of its resistance to chestnut rust. Euro-Japanese hybrids have been selected for their excellent walnut quality. Chestnuts are rich in carbohydrates and sugar while being low in fat. Its nutritional qualities and its much appreciated taste make chestnut a product sought by consumers. Most nuts produced are directly eaten fresh, roasted, fried or boiled. There are also several value-added processed products. For example, some varieties are used to make gluten-free chestnut flour. Chestnut wood is highly valued for its color, durability, and ease of work. It is widely used to make outdoor poles, furniture and flooring. The rich tannins of this wood make it very resistant to the test of time. - Kastanjapuita on viljelty Euroopassa satoja vuosia niiden pähkinöiden ja/tai puutavaran vuoksi. Vuoristoiset maat etelässä ovat perinteisesti olleet Euroopan suurimpia tuottajamaita. Nykyään terveellisten kastanjoiden tuotanto on levinnyt tasaisemmillekin alueille, vaikka kastanja on siellä edelleen marginaalilaji. Jalokastanjan taloudellinen merkitys on kastanjoista suurin. Eurooppalainen jalokastanja (Castanea sativa) on kotoisin eteläisestä Euroopasta, Aasiasta ja Pohjois-Afrikasta. Sen leveä latvus voi yltää 30 metrin korkeuteen tai ylikin puun 250-500 elinvuoden aikana. Japaninkastanja (C. crenata) tuotiin Eurooppaan, koska se on vastutuskykyinen kastanjarutolle. Eurooppalais-japanilaisia hybridejä käytetään niiden pähkinöiden erinomaisen laadun vuoksi. Kastanjoissa on runsaasti hiilihydraatteja (verrattavissa vehnään ja riisiin) ja sokereita, kun taas vain vähän rasvaa. Yhdessä runsaan maun kanssa tämä tekee kastanjoista houkuttelevia kuluttajille. Suurin osa tuotetuista pähkinöistä syödään sellaisenaan tuoreena, paahdettuna, paistettuna tai keitettynä. Useita korkeamman jalostusarvon tuotteita on myös olemassa. Joitain lajikkeita käytetään esimerkiksi gluteenittomien kastanjajauhojen tekoon tai mehiläispesiä siirretään kastanjapuutarhoihin kastanjahunajan tuotantoa varten. Kastanjan puutavaraa arvostetaan paljon sen värin, luontaisen kestävyyden ja helpon työstettävyyden vuoksi. Sitä käytetään runsaasti mm. huonekaluissa ja lattiamateriaalina. Tanniinipitoisuus tekee kastanjapuun käytöstä kestävää.

description: An exospheric kinetic solar wind model is interfaced with an observation-driven single fluid magnetohydrodynamic (MHD) model. Initially, a photospheric magnetogram serves as observational input in the fluid approach to extrapolate the heliospheric magnetic field. Then semi-empirical coronal models are used for estimating the plasma characteristics up to a heliocentric distance of 0.1AU. From there on a full MHD model which computes the three-dimensional time-dependent evolution of the solar wind macroscopic variables up to the orbit of the Earth is used. After interfacing the density and velocity at the inner MHD boundary, we compare with the results of a kinetic exospheric solar wind model based on the assumption of Maxwell and Kappa velocity distribution functions for protons and electrons respectively, as well as with \textit{in situ} observations at 1AU. This provides insight on more physically detailed processes, such as coronal heating and solar wind acceleration, that naturally arise by inclusion of suprathermal electrons in the model. We are interested in the profile of the solar wind speed and density at 1AU, in characterizing the slow and fast source regions of the wind and in comparing MHD with exospheric models in similar conditions. We calculate the energetics of both models from low to high heliocentric distances.

description: We extend the Altmann--Mavlyutov construction of homogeneous deformations of affine toric varieties to the case of toric pairs $(X, \partial X)$, where $X$ is an affine or projective toric variety and $\partial X$ is its toric boundary.

description: This paper deals with a new mathematical model to characterise the interaction between machine and work piece in a milling process. The model consists of a multi-body system representing the milling machine and a linear thermo-elastic work piece model. An extensive experimental analysis supported the development of the governing model equations. A numerical solution strategy is outlined and complemented by simulations of stable and unstable milling processes including work piece effects. The last part covers the development of a new algorithm for the stability analysis of large milling systems.

The origin of the LMC stellar bar: clues from the SFH of the bar and inner disk

description: We discuss the origin of the LMC stellar bar by comparing the star formation histories (SFH) obtained from deep color-magnitude diagrams (CMDs) in the bar and in a number of fields in different directions within the inner disk. The CMDs, reaching the oldest main sequence turnoffs in these very crowded fields, have been obtained with VIMOS on the VLT in service mode, under very good seeing conditions. We show that the SFHs of all fields share the same patterns, with consistent variations of the star formation rate as a function of time in all of them. We therefore conclude that no specific event of star formation can be identified with the formation of the LMC bar, which instead likely formed from a redistribution of disk material that occurred when the LMC disk became bar unstable, and shared a common SFH with the inner disk thereafter. The strong similarity between the SFH of the center and edge of the bar rules out significant spatial variations of the SFH across the bar, which are predicted by scenarios of classic bar formation through buckling mechanisms.

description: We derive nonstrange baryon-baryon scattering amplitudes in the nonrelativistic quark model using the ``quark Born diagram" formalism. This approach describes the scattering as a single interaction, here the one-gluon-exchange (OGE) spin-spin term followed by constituent interchange, with external nonrelativistic baryon wavefunctions attached to the scattering diagrams to incorporate higher-twist wavefunction effects. The short-range repulsive core in the NN interaction has previously been attributed to this spin-spin interaction in the literature; we find that these perturbative constituent-interchange diagrams do indeed predict repulsive interactions in all I,S channels of the nucleon-nucleon system, and we compare our results for the equivalent short-range potentials to the core potentials found by other authors using nonperturbative methods. We also apply our perturbative techniques to the N$Δ$ and $ΔΔ$ systems: Some $ΔΔ$ channels are found to have attractive core potentials and may accommodate ``molecular" bound states near threshold. Finally we use our Born formalism to calculate the NN differential cross section, which we compare with experimental results for unpolarised proton-proton elastic scattering. We find that several familiar features of the experimental differential cross section are reproduced by our Born-order result.

Measurement and simulation of a droplet population in a turbulent flow field

description: The interaction of a disperse droplet population (spray) in a turbulent flow field is studied by combining wind tunnel experiments with simulations based on the model of a population balance system. The behavior of the droplets is modeled numerically by a population balance equation. Velocities of the air and of the droplets are determined by non-intrusive measurements. A direct discretization of the 4D equation for the droplet size distribution is used in the simulations. Important components of the numerical algorithm are a variational multiscale method for turbulence modeling, an upwind scheme for the 4D equation and a pre-processing approach to evaluate the aggretation integrals. The simulations of this system accurately predict the modifications of the droplet size distribution from the inlet to the outlet of the measurement section. Since the employed configuration is simple and considering that all measurement data are freely available thanks to an Internet-based repository, the considered experiment is proposed as a benchmark problem for the simulation of disperse two-phase turbulent flows.

description: A flight may be late departing or arriving from an airport because of the delays that occurred earlier on that day.
 From a small amount of initial delay, it can propagate and compromise on-time performance of the overall operations of the
 same aircraft. It can propagate on the next legs and compromise other flights as well which causes disruption in the network. A lot
 of research has been done in the area of flight delay propagation and many models were created to help airlines and operators reduce that very same effect. The Time Based Separation (TBS) project has brought new methods for separation of arrivals by time instead of distance. It’s a promising method for reducing flight delays. In this paper, by collecting flight records data from the Central Office for Delay Analysis in EUROCONTROL, we’ve observed a significant decrease in delays in case of strong headwinds, which
 proves the very point of TBS’s effectiveness in optimizing runway throughput and network operations. The dataset consisted of around 60’000 flights at London Heathrow airport. By using that data, a few analyses are executed which show us the overall effect on the network.

description: Drivable free space information is vital for autonomous vehicles that have to plan evasive maneuvers in real-time. In this paper, we present a new efficient method for environmental free space detection with laser scanner based on 2D occupancy grid maps (OGM) to be used for Advanced Driving Assistance Systems (ADAS) and Collision Avoidance Systems (CAS). Firstly, we introduce an enhanced inverse sensor model tailored for high-resolution laser scanners for building OGM. It compensates the unreflected beams and deals with the ray casting to grid cells accuracy and computational effort problems. Secondly, we introduce the 'vehicle on a circle for grid maps' map alignment algorithm that allows building more accurate local maps by avoiding the computationally expensive inaccurate operations of image sub-pixel shifting and rotation. The resulted grid map is more convenient for ADAS features than existing methods, as it allows using less memory sizes, and hence, results into a better real-time performance. Thirdly, we present an algorithm to detect what we call the 'in-sight edges'. These edges guarantee modeling the free space area with a single polygon of a fixed number of vertices regardless the driving situation and map complexity. The results from real world experiments show the effectiveness of our approach.

description: Achieving crash consistency in persistent memory (PM) applications is difficult due to the need for fine-granular cache flushes and memory fences. File systems are no exception. Previous works have found numerous bugs in PM file systems, but crash consistency testing as part of file system development is still rare. With this paper, we make crash consistency testing easier by improving Vinter, a crash consistency testing tool for file systems based on virtual machines. We introduce support for cross-media file systems with NVMe and PM that are not covered by other testing tools. To speed up testing, we add an alternative algorithm for simulating crashes that focuses on logic bugs rather than misuse of PM primitives.

description: We consider a diffuse interface model which describes the motion of an incompressible isothermal mixture of two immiscible fluids. This model consists of the Navier-Stokes equations coupled with a convective nonlocal Cahn-Hilliard equation. Several results were already proven by two of the present authors. However, in the two-dimensional case, the uniqueness of weak solutions was still open. Here we establish such a result even in the case of degenerate mobility and singular potential. Moreover, we show the strong-weak uniqueness in the case of viscosity depending on the order parameter, provided that the mobility is constant and the potential is regular. In the case of constant viscosity, on account of the uniqueness results we can deduce the connectedness of the global attractor whose existence was obtained in a previous paper. The uniqueness technique can be adapted to show the validity of a smoothing property for the difference of two trajectories which is crucial to establish the existence of an exponential attractor.

description: Modern HPC and AI Computing solutions regularly use GPUs as their main source of computational power. This creates a significant imbalance for storage operations for GPU applications, as every such storage operation has to be signalled to and handled by the CPU. In GPU4FS, we propose a radical solution to this imbalance: Move the file system implementation to the application, and run the complete file system on the GPU. This requires multiple changes to the complete file system stack, from the actual storage layout up to the file system interface. Additionally, this approach frees the CPU from file system management tasks, which allows for more meaningful usage of the CPU. In our pre- liminary implementation, we show that a fully-featured file system running on GPU with minimal CPU interaction is possible, and even bandwidth-competitive depending on the underlying storage medium.
Properties of Minimizers of Average-Distance Problem via Discrete Approximation of Measures

description: Given a finite measure µ with compact support, and λ > 0, the averagedistance problem, in the penalized formulation, is to minimize (0.1) E λ µ (Σ) := Z Rd d(x, Σ)dµ(x) + λH1 (Σ), among pathwise connected, closed sets, Σ. Here d(x, Σ) is the distance from a point to a set and H1 is the 1-Hausdorff measure. In a sense the problem is to find a onedimensional measure that best approximates µ. It is known that the minimizer Σ is topologically a tree whose branches are rectifiable curves. The branches may not be C 1 , even for measures µ with smooth density. Here we show a result on weak second-order regularity of branches. Namely we show that arc-length-parameterized branches have BV derivatives and provide a priori estimates on the BV norm. The technique we use is to approximate the measure µ, in the weak-∗ topology of measures, by discrete measures. Such approximation is also relevant for numerical computations. We prove the stability of the minimizers in appropriate spaces and also compare the topologies of the minimizers corresponding to the approximations with the minimizer corresponding to µ.
