title: Mechanical and Hydraulic Aspects of Rock-Proppant Systems : Laboratory Experiments and Modelling Approaches
Creators: name: Reinicke, Andreas
Publisher: name: Deutsches GeoForschungsZentrum GFZ
Year: 2011

description: [...] In context of this work, a new damage mechanism is proposed: the mechanically inducedfracture face skin. This new mechanism results from mechanical interactions between the proppants and the reservoir rock, due to the increasing stress on the rock-proppant system during production. Proppant embedment into the fracture face and proppant crushing leads to fines production and can impair the fracture performance. In order to achieve sustainable, longterm productivity from a reservoir, it is indispensable to understand the hydraulic and mechanical interactions in the rock-proppant system.In order to analyse the hydraulic and mechanical interactions, laboratory experiments using three different flow cells were conducted. These flow cells were used to localise and quantify the mechanical damage at the fracture face, as well as to investigate the long-term stability of a rock-proppant system under in-situ reservoir conditions.

description: Atherosclerosis is the most frequent cause of death globally. Oxidized low-density lipoprotein (ox-LDL) has an essential role in the formation of atherosclerotic plaques and foamy macrophages. Ox-LDL increases the uptake of cholesterol by macrophages and is the major cause of blood flow disruption. Ox-LDL is produced during oxidative stress and treatment with antioxidants could inhibit the production and function of ox-LDL. Curcumin is a potent antioxidant and has a strong track record in the treatment of numerous diseases. Recent studies indicate that Curcumin exerts a lipid-lowering effect, and can modulate the formation of atherosclerotic plaque. The current review focuses upon the role of Curcumin in oxidation of LDL and foam cell formation in atherosclerotic lesions.

Learning Multi-View Aggregation In the Wild for Large-Scale 3D Semantic Segmentation

description: Recent works on 3D semantic segmentation propose to exploit the synergy between images and point clouds by processing each modality with a dedicated network and projecting learned 2D features onto 3D points. Merging large-scale point clouds and images raises several challenges, such as constructing a mapping between points and pixels, and aggregating features between multiple views. Current methods require mesh reconstruction or specialized sensors to recover occlusions, and use heuristics to select and aggregate available images. In contrast, we propose an end-to-end trainable multi-view aggregation model leveraging the viewing conditions of 3D points to merge features from images taken at arbitrary positions. Our method can combine standard 2D and 3D networks and outperforms both 3D models operating on colorized point clouds and hybrid 2D/3D networks without requiring colorization, meshing, or true depth maps. We set a new state-of-the-art for large-scale indoor/outdoor semantic segmentation on S3DIS (74.7 mIoU 6-Fold) and on KITTI-360 (58.3 mIoU). Our full pipeline is accessible at https://github.com/drprojects/DeepViewAgg, and only requires raw 3D scans and a set of images and poses.

title: Sensitivity analysis for future gravity satellite missions
Creators: name: Einarsson, Indriði
Publisher: name: Deutsches GeoForschungsZentrum GFZ
Year: 2011

description: The theme of this thesis is to investigate the sensitivity of several different formations of future satellite gravity missions. The work has three main aspects. The first, and the most important, is the development and testing of a global directional wavelet transformation as a mathematical tool to analyse sensitivity of satellite gravity mission. This is done by propagating full covariance matrices w.r.t. the spherical harmonics functions onto the directional wavelet transform. For the first time, we are able to accurately quantify the stripes that are typical for the error pattern of the GRACE gravity mission.The second aspect is the simulation of a satellite gravity formation, in order to achieve accuracy information in the form of a full covariance matrix. The third aspect involves analyzing results from the GRACE mission, which is already in orbit and has been delivering data since 2002. We compare the simulations of GRACE to the data delivered by the GRACE mission. This way, we are able to establish a relationship between the simulations and real-life data and evaluate the quality of the simulations.

Existence of weakly quasisymmetric magnetic fields in asymmetric toroidal domains with non-tangential quasisymmetry
Creators: name: Sato, Naoki
Publisher: name: arXiv
Year: 2022
Subjects: subject: Plasma Physics (physics.plasm-ph)
subject: FOS: Physical sciences

description: A quasisymmetry is a special symmetry that enhances the ability of a magnetic field to trap charged particles. Quasisymmetric magnetic fields may allow the realization of next generation fusion reactors (stellarators) with superior performance when compared with classical (tokamak) designs. Nevertheless, the existence of such magnetic configurations lacks mathematical proof due to the complexity of the governing equations. Here, we prove the existence of weakly quasisymmetric magnetic fields by constructing explicit examples. This result is achieved by a tailored parametrization of both magnetic field and hosting toroidal domain, which are optimized to fulfill quasisymmetry. The obtained solutions hold in a toroidal volume, are smooth, possess nested flux surfaces, are not invariant under continuous Euclidean isometries, have a non-vanishing current, exhibit a direction of quasisymmetry that is not tangential to the toroidal boundary, and fit within the framework of anisotropic magnetohydrodynamics.

description: The CDF collaboration has recently published a precision measurement of the W-boson mass that differs from the Standard Model prediction by seven standard deviations. This result can be explained with additional electroweak multiplets that either break the custodial symmetry or contribute to oblique parameters at loop level. Here, we study one of the best-motivated scenarios involving new multiplets: the type-II seesaw model, which involves a scalar triplet that generates Majorana neutrino masses and can furthermore resolve the W-boson mass discrepancy. This favors a doubly-charged scalar with mass between 100 and 200 GeV as well as other scalars with a fixed mass splitting. The entire preferred parameter space is testable at the LHC.

description: Giant planets have been discovered at large separations from the central star. Moreover, a striking number of young circumstellar disks have gas and/or dust gaps at large orbital separations, potentially driven by embedded planetary objects. To form massive planets at large orbital separations through core accretion within disk lifetime, however, an early solid body to seed pebble and gas accretion is desirable. Young protoplanetary disks are likely self-gravitating, and these gravitoturbulent disks may efficiently concentrate solid material at the midplane driven by spiral waves. We run 3D local hydrodynamical simulations of gravitoturbulent disks with Lagrangian dust particles to determine whether particle and gas self-gravity can lead to the formation of dense solid bodies, seeding later planet formation. When self-gravity between dust particles is included, solids of size $\mathrm{St} = 0.1$ to $1$ concentrate within the gravitoturbulent spiral features and collapse under their own self-gravity into dense clumps up to several $M_{\oplus}$ in mass at wide orbits. Simulations with dust that drift most efficiently, $\mathrm{St}=1$, form the most massive clouds of particles, while simulations with smaller dust particles, $\mathrm{St}=0.1$, have clumps with masses an order of magnitude lower. When the effect of dust backreaction onto the gas is included, dust clumps become smaller by a factor of a few but more numerous. The existence of large solid bodies at an early stage of the disk can accelerate the planet formation process, particularly at wide orbital separations, and potentially explain planets distant from the central stars and young protoplanetary disks with substructures.

description: A Proton Exchange Membrane Fuel Cell (PEMFC) provides stable, emission-free, high-efficiency power. Water management and durability of PEMFCs are directly affected by transport phenomena at the cathode side. In the present study, transport phenomena are investigated and optimized in a tapered parallel flow field. Main channels in the flow field are tapered, which increases limiting current density by 41%. Two objectives, i.e. water saturation and transport resistance, are considered metrics for transport phenomena in a tapered parallel flow field PEMFC. Operating pressure, temperature, stoichiometries at both sides, and the porosity of gas diffusion layers are selected as parameters to be optimized. Two functions are generated for objectives by integrating 3D multiphase-flow computational fluid dynamics and Response Surface Methodology. Multi-Objective Optimization (MOO) is carried out with two different methods. Multi-Objective Particle Swarm Optimization (MOPSO) and Non-dominated Sorting Genetic Algorithm II (NSGA-II) are employed to produce two challenging Pareto fronts. The results demonstrate that MOPSO performs better than NSGA-II. MOPSO recognized quite the same Pareto front with lower runtime. In the last step, the Technique of Order Preference Similarity to the Ideal Solution (TOPSIS) is used to select an optimum point from the Pareto front. The results are compared against experimental data, and good correspondence is observed. The optimum features are temperature 323, pressure 1 atm, anode stoichiometry 3, cathode stoichiometry 2.62, and porosity 0.68. The porosity and pressure played the most significant roles in determining water saturation and resistance.

description: Abstract

Lornoxicam is a Biopharmaceutics Classification System (BCS) Class II drug prescribed for rheumatoid arthritis and osteoarthritis. It is potent analgesic and anti-inflammatory agent but has poor aqueous solubility (pka 4.7) that reduces its oral absorption and pharmacological effect. The aim of the present study was to formulate polymeric nanoparticles of lornoxicam with increase aqueous solubility and better anti-inflammatory effect using anti-solvent precipitation method. A 22 full factorial design was used taking chitosan and soluplus® as independent variables whereas average particle size (z-average), % drug release and polydispersity index (PDI) as dependent variables. Four formulations fabricated, subjected to dynamic light scattering, in-vitro drug release (pH 1.2 HCl and pH 6.8 phosphate buffer), PDI and encapsulation efficiency. The results showed good characteristic features of trial formulations in nanodimensions. The formulation (F1) containing  chitosan (80mg) and soluplus® (4mg) was selected as an optimized formulation due to less z -average (198.7±2.95nm) and PDI (0.225±0.01), stable zeta potential (-16.87±1.95) and maximum % drug release in pH 6.8 phosphate buffer (89.14±0.67%; p<0.05) comparatively to pure lornoxicam. The optimized formulation followed first order kinetics based on high R2 (0.98), low AIC (48.79) and high MSC (3.64). The drug release mechanism was studied by Higuchi model that showed diffusion and erosion pattern with good correlation coefficient. Atomic force microscopy, Fourier transform Infrared, Thermogravimetric differential scanning calorimetry and X-ray powder diffraction characterization of the optimized formulation revealed its spherical shape, stable and semi crystalline structure and well polymeric encapsulation. The F1 formulation exhibited dose dependent results at 0.1mg/kg (56.55%;p< 0.005) and 0.3mg/kg (81.11%;p<0.005) with IC50 0.06mg/kg comparatively to pure lornoxicam for the same and higher doses (1mg/kg) respectively (p<0.005). Thus, the chitosan and soluplus® in combination at higher levels appeared to be best combination in formulating lornoxicam nanoparticles that successfully enhanced aqueous solubility, % drug release and pharmacological effect. In-vivo human studies of lornoxicam nanoparticles, its role in arthritis model are recommended for future researches.

description: We initiate the studies on the structural physics of the tower of stable large-$N_c$ mesons through a first computation of the collinear quark-structure of a large-$N_c$ pion using lattice Monte-Carlo methods. We adapt the large-$N_c$ continuum reduction for the determination of meson correlation functions involving the spatially-extended quasi-PDF operators as a perfect strategy to concentrate only on the short perturbative length scales. We find the internal structures of pion in the large-$N_c$ and $N_c=3$ theories to be quite similar. Interestingly, we find hints that even the observed differences could arise to a large extent via the different perturbative QCD evolution in the two theories from similar initial conditions at low factorization scales.

description: Characterizing playing style is important for football clubs on scouting, monitoring and match preparation. Previous studies considered a player's style as a combination of technical performances, failing to consider the spatial information. Therefore, this study aimed to characterize the playing styles of each playing position in the Chinese Football Super League (CSL) matches, integrating a recently adopted Player Vectors framework. Data of 960 matches from 2016-2019 CSL were used. Match ratings, and ten types of match events with the corresponding coordinates for all the lineup players whose on-pitch time exceeded 45 minutes were extracted. Players were first clustered into 8 positions. A player vector was constructed for each player in each match based on the Player Vectors using Nonnegative Matrix Factorization (NMF). Another NMF process was run on the player vectors to extract different types of playing styles. The resulting player vectors discovered 18 different playing styles in the CSL. Six performance indicators of each style were investigated to observe their contributions. In general, the playing styles of forwards and midfielders are in line with football performance evolution trends, while the styles of defenders should be reconsidered. Multifunctional playing styles were also found in high rated CSL players.

description: The Workshop focus was on the specific safety requirements of railbound transportation systems. For the latter, early warning is crucial not only because of the long braking times of trains but also because of the high demands on track geometry and stability necessary for safe train operation. In addition, after a natural disaster, reliable and fast information about the state of the railway infrastructure (damage map) is of utmost importance in order to mitigate the consequences of the disaster.During two days experts from the fields of seismology, sensor technology, railway engineering, computer science, and railway safety reviewed the state of the art and the potential of early warning for transportation systems. Major workshop topics were– seismic early warning and sensors,– early warning of endangered trains,– damage assessment for railway infrastructure,– modern geo-standard based information systems,– train control and safety strategies.Another purpose of the workshop was to delineate the possibilities and limitations of a railway infrastructure integrated network of accelerometers that can be used for permanent structural health monitoring and earthquake early warning.

description: The ESA Ariel mission has been adopted for launch in 2029 and will conduct a survey of around one thousand exoplanetary atmospheres during its primary mission life. By providing homogeneous datasets, with a high SNR and wide wavelength coverage, Ariel will unveil the atmospheric demographics of these far-away worlds, helping to constrain planet formation and evolution processes on a galactic scale. Ariel seeks to undertake a statistical survey of a diverse population of planets and, therefore, the sample of planets from which this selection can be made is of the utmost importance. While many suitable targets have already been found, hundreds more will be discovered before the mission is operational. Previous studies have used predictions of exoplanet detections to forecast the available planet population by the launch date of Ariel, with the most recent noting that the Transiting Exoplanet Survey Satellite (TESS) alone should provide over a thousand potential targets. In this work, we consider the planet candidates found to date by TESS to show that, with the addition of already confirmed planets, Ariel will already have a more than sufficient sample to choose its target list from once these candidates are validated. We showcase the breadth of this population as well as exploring, for the first time, the ability of Ariel to characterise multiple planets within a single system. Comparative planetology of worlds orbiting the same star, as well as across the wider population, will undoubtedly revolutionise our understanding of planet formation and evolution.

Interaction of vortex stretching with wind power fluctuations

Publisher: name: arXiv
Year: 2022
Subjects: subject: Fluid Dynamics (physics.flu-dyn)
subject: FOS: Physical sciences

description: The transfer of turbulence kinetic energy from large to small scales occurs through vortex stretching. Also, statistical properties of the subgrid-scale energy fluxes depend on the alignment of the vorticity vector with the principal strain axis. A heuristic analysis of the present study indicates that vortex-stretching and the second invariant of the velocity gradient tensor provide a scale-adaptive parameterization of the subgrid-scale stresses and the local energy fluxes in the wakes of wind turbines. The scale-adaptivity underlies the restricted Euler dynamics of the filtered motion that vortex-stretching plays in the growth of the second invariant of filtered velocity gradient and the local energy transfer. We have analyzed wind power fluctuations in a utility-scale wind farm with $41$ actuator disks. The numerical results show that the spectrum of the wind power fluctuations follows a power law with a logarithmic slope of $-5/3$. Furthermore, POD analysis indicates that the wind power fluctuations depend on the incoming turbulence and its modulation by the wake interactions in wind farms.

description: An ab initio QED approach to treat a valence-hole excitation in closed shell systems is developed in the framework of the two-time-Green function method. The derivation considers a redefinition of the vacuum state and its excitation as a valence-hole pair. The proper two-time Green function, whose spectral representation confirms the poles at valence-hole excitation energies is proposed. An contour integral formula which connects the energy corrections and the Green function is also presented. First-order corrections to the valence-hole excitation energy involving self-energy, vacuum polarization, and one-photon-exchange terms are explicitly derived in the redefined vacuum picture. Reduction to the usual vacuum electron propagators is given that agrees in the Breit approximation with the many-body perturbation theory expressions for the valence-hole excitation energy.

description: Antimony telluroiodide (SbTeI) is predicted to be a promising material in many technological applications based on theoretical simulations, however the bulk structure solution remains elusive. We consolidate SbTeI belonging to the base-centered monoclinic lattice with a space group C 2/m by combining single crystal X-ray diffraction and X-ray photoemission spectroscopy techniques. The atomic arrangement of the reported crystal structure is remarkable with one-dimensional double-chains forming two-dimensional blocks. In this structure, the Sb$^{3+}$ ion is surrounded by Te$^{2-}$ and I$^-$, which is distinguishable by an incomplete polyhedron resulting in the 5s$^2$ (Sb) lone pair electrons in the valence band. Manipulation of this material with pressure to induce novel structures and properties is highly anticipated.

description: Scolopendrelloides dolosa (Ribaut 1914), new combination
Hanseniella dolosa Ribaut 1914: pag. 43, figs. 10–20.
Material examined. 1 paratype from Kenya MNHN K27.
Length 1.3 mm.
The observed specimen was pretty damaged and wrinkled. However, it was possible to observe some interesting features. The head is distinctly heart-shaped and somewhat flattened laterally (Fig. 4 A, C). That the central rod is complete until the posterior end of the head, where it seem to form a triangular area. The transversal fold of the head seems to be the lateral branches of the central rod. Only the exterior opening of the Tömösváry’s organ is visible (Fig. 4 C, arrow). The tergites are emarginated posteriorly, with small tips, not visible in all tergites (Fig. 4 A, B). Lateral machrochaetae are present on all tergites and the presence of a single pair in the penultimate one is characteristic of this species (Fig. 4 D). Cuticle of tergites glabrous. Cerci conical, with straight angles and a moderate number of setae (Fig. 4 D). The trichobothria’s pit do not present conspicuous setae.

description: The analysis of the GRACE (Gravity Recovery And Climate Experiment) gravity field observations has already proved the feasibility to determine mass variations especially with respect to continental hydrology in different geographical regions. Daily and monthly solutions of the gravity field have been determined, showingclearly temporal gravity field variations closely correlated to the hydrological watercycle and other time dependent processes in the Earth system. In the following, the GRACE gravity field model ITG-Grace2010 will be presented. It has been determined using the short arc method and consists of three parts: ITG-Grace2010s as static Earth’s gravity field solution up to degree 180, unconstrained monthly GRACE solution up to degree 120 and daily snapshots based on Kalman smoother up to degree 40.

description:
Pädagogische Beziehungen spielen in der Lehrpersonenbildung der Schweiz eine wichtige Rolle. Sie sind dort sowohl als Thema in Lehrveranstaltungen als auch in der interaktiven Gestaltung präsent.

Im qualitativ-rekonstruktiven Beitrag wird untersucht, welche Positionen und Vorstellungen zur Gestaltung pädagogischer Beziehungen Studierenden in einer Lehrveranstaltung zum Sachunterricht nahegelegt werden, die u. a. den ‚Lebensweltbezug‘ thematisiert. Die Rekonstruktion zeigt eine Spannung zwischen der Thematisierung pädagogischer Beziehungen und der performativ realisierten Beziehung des Dozenten zu den Studierenden. Im Beitrag werden das methodische Vorgehen und die Rekonstruktion dargestellt, bevor die Ergebnisse in ihrer Bedeutung und ihren Limitationen diskutiert werden.

description:
Pedagogical relationships play an important role in teacher education not only in Switzerland, both as a topic in courses and in the interactive performance of teaching student teachers. By using a qualitative-reconstructive methodology this paper examines which positions and ideas on the design of pedagogical relationships are suggested to students in a course on social and science studies. The reconstruction shows a tension between the thematization of pedagogical relationships and the performatively realised relationship of the lecturer to the students. The article describes the methodological procedure and the reconstruction before discussing significance and limitations of the results.

description: The International Geomagnetic Reference Field (IGRF) is a very frequently used model of the Earth’s main magnetic field by both the science community and the industry. This model is updated every five years. We present here the second generation of the GRIMM magnetic field model that was derived to contribute to the IGRF-11. The model has been developed from a newly, reprocessed CHAMP satellite data set covering nearly 10 years. It has a temporal and spatial resolution significantly improved compared to previous models.

description: Abstract

Important Clarification: This theory is not an extension of Rejection Sensitivity Dysphoria (RSD). It is a replacement. RSD was the first clinical recognition of this experience, but it failed to capture the full neurological collapse, identity fragmentation, and relational damage at the heart of the condition. Emotional Overload Disorder (EOD) is not a more detailed RSD — it is the true architecture that RSD only hinted at

A Survey of Strong Cosmic Censorship Conjecture Beyond Einstein's Gravity

description: The strong cosmic censorship conjecture (SCCC) proposed by Penrose states that the presence of the inner Cauchy horizon ($\mathcal{CH}$) in the black hole solutions does not threaten the deterministic nature of general relativity since it is actually unstable against the remnant perturbation fields that fall into the black hole. Although this conjecture is well-established for the asymptotically flat spacetimes in general relativity, it is challenged upon taking a small positive cosmological constant as required by observational data. This challenge can be fixed by finding even one type of quasi-normal mode whose decay rate is slow enough insofar as the remnant of perturbation is able to destroy the $\mathcal{CH}$. By aiming to investigate the role of the additional parameter induced by modified gravity in this scenario, we consider the charged-de Sitter black hole solutions of Einstein-Maxwell theory extended with $f(R)$ and Energy-Momentum Squared Gravities. Employing the numerical analysis of the deterministic criterion, we show that the presence of the model parameter of theories at hand within a given range controls the decay rate of the photon sphere quasi-normal modes (in the eikonal limit) to rescue SCCC.

description: In this paper we present a spectroscopic study of six double-lined binaries, five of which were recently discovered in a high-resolution spectroscopic survey of optical counterparts of stellar X-ray sources. Thanks to high-resolution spectra acquired with CAOS spectropolarimeter during seven years, we were able to measure the radial velocities of their components and determine their orbital elements. We have applied our code COMPO2 to determine the spectral types and atmospheric parameters of the components of these spectroscopic binaries and found that two of these systems are composed of main sequence stars, while the other four contain at least one evolved (giant or subgiant) component, similar to other well-known RS CVn systems. The subtraction of a photospheric template built up with spectra of non-active stars of the same spectral type as those of the components of each system has allowed us to investigate the chromospheric emission that fills in the H$α$ cores. We found that the colder component is normally the one with the largest H$α$ emission. None of the systems show a detectable LiI$λ$6708 line, with the exception of TYC 4279-1821-1, which exhibits high photospheric abundances in both components. Photometric time series from the literature allowed us to assess that the five systems with a nearly circular orbit have also photometric periods close or equal to the orbital ones, indicating spin-orbit synchronization. For the system with a highly eccentric orbit, a possible pseudo-synchronization with the periastron velocity is suggested.
