description: The exclusive photoproduction of upsilon states $Υ(1S)$ and its radially excited states $Υ(2S,3S)$ is investigated in the context of ultra-peripheral collisions at the LHC energies. Predictions are presented for their production in proton-proton, proton-nucleus and nucleus-nucleus collision at the energies available at the LHC run 2. The rapidity and transverse momentum distributions are shown, and the robustness of the model is tested against the experimental results considering $ψ(1S,2S)$ and $Υ(1S)$ states. The theoretical framework considered in the analysis is the light-cone color dipole formalism, which includes consistently parton saturation effects and nuclear shadowing corrections.

description: Experiments based on cavity quantum electrodynamics (QED) are widely used to study the interaction of a light field with a discrete frequency spectrum and emitters. More recently, the field of waveguide QED has attracted interest due to the strong interaction between propagating photons and emitters that can be obtained in nanophotonic waveguides, where a continuum of frequency modes is allowed. Both cavity and waveguide QED share the common goal of harnessing and deepening the understanding of light-matter coupling. However, they often rely on very different experimental set-ups and theoretical descriptions. Here, we experimentally investigate the transition from cavity to waveguide QED with an ensemble of cold atoms that is coupled to a fiber-ring resonator, which contains a nanofiber section. By varying the length of the resonator from a few meters to several tens of meters, we tailor the spectral density of modes of the resonator while remaining in the strong coupling regime. We demonstrate that for progressively longer resonators, the paradigmatic Rabi oscillations of cavity QED gradually vanish, while non-Markovian features reminiscent of waveguide QED appear.

description: Background: Esophageal cancer is the eighth leading cancer case and the top sixth cause of cancer mortality worldwide. In Ethiopia esophageal cancer ranks the seventh and eighth as the leading cause of cancer mortality and morbidity respectively according to Globocan 2012 estimate. Objectives: The objective of this study is to assess histologic type, treatment pattern, outcome and factors associated with treatment outcome of esophageal cancer Patients at Tikur Anbessa Specialized Hospital Addis Ababa, Ethiopia. Methods: A retrospective cross sectional study using record review was employed at surgical oncology department, radiotherapy and chemotherapy treatment center of Tikur Anbessa Specialized Hospital. All newly confirmed esophageal cancer patients (n=349) who were registered at Tikur Anbessa Specialized Hospital from January 2010 to December 2016 were included in this study. Patients chart was reviewed and telephone interview was made to generate all variables required for the study from March to April 2017.Finally basic descriptive statistics ( frequency ,mean , median and tables ), bivariate and multivariable analysis was performed and statistical significance were ascertained with 95% CI at 0.05 alpha level. Result: A total of 349 esophageal cancer patients charts were reviewed. From a total of cases that were registered during seven years period there were 287 (90.3%) cases of squamous cell carcinoma. Surgery was done for 183(52.4%) of cases, 89(25.5%) received chemotherapy and 26 (7.4%) took radiotherapy which is palliative type. From all esophageal cancer patients who were included in this study 310 (88.8%) were not alive at a time of the study period. Only Chemotherapy (AOR 2.80(95%CI of 1.22, 6.41) and surgery (AOR 0.287 (95%CI 0.126, 0.625) were found to be factors associated with death from esophageal cancer. Conclusion: squamous cell carcinoma was the most predominant histologic type followed by adenocarcinoma affecting males and females equally. Most of the esophageal cancer patients were diagnosed in advanced stages affecting the treatment outcome of esophageal patients. Surgery was the most frequent treatment modality in the hospital, overall sex of patients, surgery and chemotherapy has significant association with treatment outcome of esophageal cancer patients.

description: Assuming the validity of the relativity principle, we discuss the implications on relativistic kinematics of a deformation of the Poincaré invariance that preserves the Poincaré algebra, and only modifies its action on phase space in a Lorentz-invariant way. We show that, in contrast to the case where the Poincaré algebra is deformed, the action of boosts on two-particle states is not affected, while the addition law of momenta is to a large extent arbitrary. We give some nontrivial examples of this arising from doubly special relativity and noncommutative geometry and show that Hopf-algebra methods give equivalent results.

description: Context: Several observations of the local Universe (LU) point towards the existence of very prominent structures. The presence of massive galaxy clusters and local super clusters on the one hand, but also large local voids and under-densities on the other hand. However, it is highly non trivial to connect such different observational selected tracers to the underlying dark matter (DM) distribution. Methods (abridged): We used a 500 Mpc/h large constrained simulation of the LU with initial conditions based on peculiar velocities derived from the CosmicFlows-2 catalogue and follow galaxy formation physics directly in the hydro-dynamical simulations to base the comparison on stellar masses of galaxies or X-ray luminosity of clusters. We also used the 2668 Mpc/h large cosmological box from the Magneticum simulations to evaluate the frequency of finding such anomalies in random patches within simulations. Results: We demonstrate that haloes and galaxies in our constrained simulation trace the local DM density field very differently. Thereby, this simulation reproduces the observed 50% under-density of galaxy clusters and groups within the sphere of ~100 Mpc when applying the same mass or X-ray luminosity limit used in the observed cluster sample (CLASSIX), which is consistent with a ~1.5$σ$ feature. At the same time, the simulation reproduces the observed over-density of massive galaxy clusters within the same sphere, which on its own also corresponds to a ~1.5$σ$ feature. Interestingly, we find that only 44 out of 15635 random realizations (i.e. 0.28%) are matching both anomalies, making the LU to be a ~3$σ$ environment. We finally compared a mock galaxy catalogue with the observed distribution of galaxies in the LU, finding also a match to the observed factor of two over-density at ~16 Mpc as well as the observed 15% under-density at ~40 Mpc distance.

description: We study the prospect of measuring the electroweak quantum numbers of beyond the Standard Model (SM) color sextet particles that decay into same-sign top quark pairs. Among these particles, the color sextet scalars give rise to top quarks with the same chirality, while the top quarks coming from the color sextet vector would have opposite chirality. This difference gets encoded in the angular distributions of the bottom quarks and leptons originating from the decays of the top quarks. We utilize this feature and the energy distributions of the final state jets and leptons to distinguish among the three possible color sextet resonances, taking into account various SM background processes at the $13$ TeV LHC.

description: Artificial spin-orbit coupling in optical lattices can be engineered to tune band structure into extreme regimes where the single-particle band flattens leaving only inter-particle interactions to define many-body states of matter. Lin et al. [Phys. Rev. Lett 112, 110404 (2014)] showed that under such conditions interactions lead to a Wigner crystal of fermionic atoms under approximate conditions: no bandwidth or band mixing. The excitations were shown to possess emergent kinetics with fractionalized charge derived entirely from interactions. In this work we use numerical exact diagonalization to study a more realistic model with non-zero bandwidth and band mixing. We map out the stability phase diagram of the Wigner crystal. We find that emergent properties of the Wigner crystal excitations remain stable for realistic experimental parameters. Our results validate the approximations made by Lin et al. and define parameter regimes where strong interaction effects generate emergent kinetics in optical lattices.
Quantifying interaction mechanism in infinite layer nickelate superconductors

Subjects: subject: Superconductivity (cond-mat.supr-con)

description: The relationship between the long-range antiferromagnetic order in cuprates and the high-temperature superconductivity in these compounds represents unresolved, nearly four-decades long scientific problem. Because recently discovered nickelate superconductors are crystallographical counterparts of cuprates, many properties and difficulties into describing these compounds are common to both families. Recently, Fowlie et al (2022 Nature Physics 18 1043) aimed to detect the antiferromagnetic order in $R_{1-x}Sr_{x}NiO_{2}$ (R = Nd, Pr, La, x ~ 0.2) films by using the muon spin rotation (muSR) technique. This research group reported on the existence of short-range antiferromagnetic order in all studied nickelates. Here, we aimed to reveal the existence of this interaction in the same nickelate films by analyzing the temperature dependent resistivity, $ρ(T)$, reported by the same research group. Global $ρ(T)$ data fits to the advanced Bloch-Grüneisen model showed that each of R1-xSrxNiO2 compounds can be characterized by a unique power-law exponent, p (where p=2 for the electron-electron scattering, p=3 for the electron-magnon scattering, and p=5 for the electron-phonon scattering), and global characteristic temperature, $T_ω$ (which has the meaning of the Debye temperature at p=5). We found that p=2.0 in Nd- and Pr-based compounds, and p=1.3 for La-based compound. The latter value does not have any interpretation within established theoretical models. We also analyzed $ρ(T)$ data for $Nd_{1-x}Sr_{x}NiO_{2}$ (0.125 < x < 0.325) reported by Lee et al (2022 arXiv2203.02580). Because our analysis showed that p-values in nickelates are remarkably different from p=3, we call for the developent of a new theoretical model to describe $ρ(T)$ in materials exhibiting a short-range antiferromagnetic order.

description: The weak ergodicity breaking hypothesis postulates that out-of-equilibrium glassy systems lose memory of their initial state despite being unable to reach an equilibrium stationary state. It is a milestone of glass physics, and has provided a lot of insight on the physical properties of glass aging. Despite its undoubted usefulness as a guiding principle, its general validity remains a subject of debate. Here, we present evidence that this hypothesis does not hold for a class of mean-field spin glass models. While most of the qualitative physical picture of aging remains unaffected, our results suggest that some important technical aspects should be revisited.

description: In electromagnetic simulations of magnets and machines one is often interested in a highly accurate and local evaluation of the magnetic field uniformity. Based on local post-processing of the solution, a defect correction scheme is proposed as an easy to realize alternative to higher order finite element or hybrid approaches. Radial basis functions (RBF)s are key for the generality of the method, which in particular can handle unstructured grids. Also, contrary to conventional finite element basis functions, higher derivatives of the solution can be evaluated, as required, e.g., for deflection magnets. Defect correction is applied to obtain a solution with improved accuracy and adjoint techniques are used to estimate the remaining error for a specific quantity of interest. Significantly improved (local) convergence orders are obtained. The scheme is also applied to the simulation of a Stern-Gerlach magnet currently in operation.

description: In the past, the amount of plastic waste steadily increased in Germany. Plastic waste from automotive applications challenges existing mechanical recycling processes due to its material heterogeneity and complexity. However, chemical recycling via pyrolysis has the potential to recycle these plastics, obtain a high value recycled plastic with the quality of virgin material, and reduce the use of primary material. To date, no mass and energy balances are available to assess the performance of the pyrolysis process itself nor the process chain it is embedded in. This study conducted experiments with automotive plastic waste from garages in a pyrolysis screw reactor. The resulting pyrolysisproducts‘ mass and elemental compositions were determined and balanced considering reasonable assumptions. It was shown that about 70 % of the automotive waste plastics‘ inherent carbon was transferred to pyrolysis oil. When considering the entire process chain from waste sorting, pyrolysis of the sorted waste, pyrolysis oil upgrading, and subsequent steam cracking producing ethane, propene, butadiene, and pyrolysis gasoline, a carbon efficiency of approximately 55 % was calculated based on the experimental data, assumptions and data from literature. Elsewhere, similar experimental results have been found for the pyrolysis of plastic waste from post-shredder treated automotive shredder residue (ASR) from end-of-life vehicles. With a yearly amount of approximately 68,000 tons of ASR in Germany, the potential of chemical recycling via pyrolysis becomes apparent. Future studies should focus on the economic and ecologic assessment and optimized performance of such a process chain. In addition, a better database for pyrolysis oil upgrading and pyrolysis oil steam cracking is needed to yield more accurate results in the assessment of chemical recycling via pyrolysis.

description: The spin-$\frac{1}{2}$ XXZ chain with easy-plane anisotropy in a transverse field describes well the thermodynamic properties of the material ${\rm Cs_2CoCl_4}$ in a wide range of temperatures and fields including the region close to the spin-flop Ising quantum phase transition. For a comparison with prospective inelastic neutron scattering experiments on this compound, we present results of an extensive numerical study of its dynamic structure factor $\mathcal{S}^{αβ}(k,ω)$ using matrix-product-state (MPS) techniques. Close to criticality, the dynamic part of the correlator $\mathcal{S}^{xx}$ longitudinal to the applied field is incoherent and possesses a small total weight as the ground state is already close to saturation. The transverse correlator $\mathcal{S}^{zz}$, on the other hand, is dominated by a coherent single-particle excitation with additional spectral weight at higher energies that we tentatively attribute to a repulsively bound pair of particles. With increasing temperature, the latter quickly fades and spectral weight instead accumulates close to zero wavevector just above the single-particle energy. On a technical level, we compare the numerical efficiency of real-time evolution to an MPS-based Chebyshev expansion in the present context, finding that both methods yield results of similar quality at comparable numerical costs.

description: Magnetic fields play an important role in astrophysical accretion discs, and in the interstellar and intergalactic medium. They drive jets, suppress fragmentation in star-forming clouds and can have a significant impact on the accretion rate of stars. However, the exact amplification mechanisms of cosmic magnetic fields remain relatively poorly understood. Here I start by reviewing recent advances in the numerical and theoretical modelling of the 'turbulent dynamo', which may explain the origin of galactic and inter-galactic magnetic fields. While dynamo action was previously investigated in great detail for incompressible plasmas, I here place particular emphasis on highly compressible astrophysical plasmas, which are characterised by strong density fluctuations and shocks, such as the interstellar medium. I find that dynamo action works not only in subsonic plasmas, but also in highly supersonic, compressible plasmas, as well as for low and high magnetic Prandtl numbers. I further present new numerical simulations from which I determine the growth of the turbulent (un-ordered) magnetic field component ($B_\mathrm{turb}$) in the presence of weak and strong guide fields ($B_0$). I vary $B_0$ over 5 orders of magnitude and find that the dependence of $B_\mathrm{turb}$ on $B_0$ is relatively weak, and can be explained with a simple theoretical model in which the turbulence provides the energy to amplify $B_\mathrm{turb}$. Finally, I discuss some important implications of magnetic fields for the structure of accretion discs, the launching of jets, and the star formation rate of interstellar clouds.

description: In dieser Arbeit wird ein neuer Algorithmus zur Rekonstruktion von Flächen aus dreidimensionalen Punktwolken präsentiert. Seine besonderen Eigenschaften sind die Rekonstruktion von offenen Flächen mit Rändern, Datensätzen mit variabler Punktdichte und die Behandlung von scharfen Kanten, d.h. Stellen mit unendlicher Krümmung. Es werden formale Argumente angegeben, die erklären, warum der Algorithmus korrekt arbeitet. Sie bestehen aus einer Definition von 'Rekonstruktion' und dem Beweis der Existenz von Punktmengen für die der Algorithmus erfolgreich ist. Diese mathematische Analyse konzentriert sich dabei auf kompakte Flächen mit beschränkter Krümmung und ohne Ränder. Weitere Beiträge sind die Anwendung des Flächenrekonstruktionsverfahrens für die interaktive Modellierung von Flächen und eine Prozedur für die Glättung von verrauschten Punktwolken. Zusätzlich kann der Algorithmus leicht für die lokal beschränkte Rekonstruktion eingesetzt werden, wenn nur ein Teil des Datensatzes zur Rekonstruktion herangezogen werden soll.
description: In this thesis a new algorithm for the reconstruction of surfaces from three-dimensional point clouds is presented. Its particular features are the reconstruction of open surfaces with boundaries, data sets with variable density, and the treatment of sharp edges, that is, locations of infinite curvature. We give formal arguments which explain why the algorithm works well. They consist of a definition of 'reconstruction', and the demonstration of existence of sampling sets for which the algorithm is successful. This mathematical analysis focuses on compact surfaces of limited curvature without boundary. Further contributions are the application of the surface reconstruction algorithm for interactive shape design and a smoothing procedure for noise elimination in point clouds. Additionally, the algorithm can be easily applied for locally-restricted reconstruction if only a subset of the data set has to be considered for reconstruction.

description: In this article we explicitly determine the Weierstrass semigroup at any point and the full automorphism group of a known $\mathbb{F}_{q^2}$-maximal curve $\mathcal{X}_3$ having the third largest genus. This curve arises as a Galois subcover of the Hermitian curve, and its uniqueness (with respect to the value of its genus) is a well-known open problem. Knowing the Weierstrass semigroups may provide a key towards solving this problem. Surprisingly enough $\mathcal{X}_3$ has many different types of Weierstrass semigroups and the set of its Weierstrass points is much richer than the set of $\mathbb{F}_{q^2}$-rational points, as instead happens for all the known maximal curves where the Weierstrass points are known. We show that a similar exceptional behaviour does not occur in terms of automorphisms, that is, $\mathrm{Aut}(\mathcal{X}_3)$ is exactly the automorphism group inherited from the Hermitian curve, apart from small values of $q$.

description: Die Sprachheilpädagogik bildet an den Hochschulen seit den 70er Jahren Diplom-Pädagogen aus, deren Arbeitsfeld im klinisch-therapeutischen Bereich der Sprachförderung und -rehabilitation liegt. Die Arbeit geht von der Frage aus, warum die Sprachheilpädagogik, die in einer Paradigmenkonkurrenz zur Phoniatrie steht, trotz einer hundertjährigen Historie bei der Therapie von Sprachstörungen zunehmende Konkurrenz- und Verdrängungskonflikte im Handlungsfeld der außerschulischen Sprachtherapie führen muss. Darüber hinaus wurde gefragt, ob konzeptuelle Divergenzen zwischen dem schulischen und dem klinischen Handlungsfeld von Sprachheilpädagogen existieren und historisch verankert sind. Zur Beantwortung wurden der Forschungsweg und eine Forschungsmethodik entwickelt, die geeignet erschienen, unterstellte Zusammenhänge zwischen der Programmatik und der Pragmatik des Fachs zu erkennen sowie sozial- und ideengeschichtliche Bedingungsfaktoren für das Entstehen der klinisch-therapeutischen Handlungsfelder von Sprachheilpädagogen zu berücksichtigen. Mittels einer Methodenkombination aus Dokumentenanalyse und Inhaltsanalyse wurden in einer Analogie zum Inhaltsanalytischen Ablaufmodell nach Mayring Kategorien gebildet, die es erlaubten, aus dem Forschungsinteresse und der Problemlage hergeleitete Fragen zu bearbeiten. Aus Gründen der Transparenz und der intersubjektiven Vergleichbarkeit folgt die Auswertung des allgemein zugänglichen, umfangreichen verschrifteten Quellenmaterials einer zeithistorischen Gliederung, die Entwicklungsverläufe innerhalb und außerhalb der Sprachheilpädagogik in 10-Jahres-Schritten aufzeigt. Die Interpretation der unter Beachtung der Kategorien durchgeführten Quellenanalyse verdeutlicht, dass die Wurzeln der Sprachheilpädagogik im außerschulischen Bereich liegen, aber eine durch die Geisteswissenschaftliche Pädagogik grundgelegte Werthaltung eine theoretische und praktische Ausgrenzung des klinisch-therapeutischen Handlungsfeldes folgen ließ. In Verbindung mit sozial- und gesundheitspolitischen Normierungen, die einen Einflussverlust sprachheilpädagogischer Konzepte bedeuteten, begann erst in den 80er Jahren eine pragmatische Integration klinisch-therapeutischer Handlungsfelder in die Sprachheilpädagogik, der eine programmatisch-konzeptionelle Zusammenführung sprachheilpädagogischer Theorie und Therapie noch fehlt.

description: Die vorliegende Arbeit beschreibt die Entwicklung einer zweiphasigen Methode zur Hydroaminomethylierung von Olefinen. Dazu werden drei verschiedene Zweiphasensysteme untersucht: organische Phase/Wasser, Toluol/Triethylenglykol und organische Phase/Ionic Liquids. Insbesondere das Zweiphasensystem organische Phase/Ionic Liquids erweist sich als geeignet eine Vielzahl von Olefinen mit primären und sekundären Aminen umzusetzen. Als Katalysatorsysteme eignen sich besonders Rhodium(I)-Komplexe. Eine Wiederverwendung der katalysatortragenden Phase ist insbesondere bei Verwendung der Ionic Liquids möglich. Neben der Hydroaminomethylierung von Olefinen lassen sich in Ionic Liquids auch Tandem Hydroformylierung/intramolekulare Hemi-Acetalisierung an hydroxy-funktionalisierten Olefinen durchführen
description: This work describes the development of a two phase hydroaminomethylation process of olefines. The research concentrates on the following three biphasic systems: organic phase/water, toluene/triethylenglykol and organic phase/ionic liquids. Especially using the biphasic system organic phase/ionic liquid results in an easy reaction between olefines and primary or secondary amines. For the reaction the application of rhodium(I) complexes is particularly useful. The recycling of the catalyst bearing phase is especially guaranteed while using the ionic liquid system. Beside the hydroaminomethylation process the ionic liquid system is useful for tandem hydroformylation/intramolecular hemi-acetalisation of hydroxy-functionalized olefines.

description: Background: A referral system is the interrelationships and coordination of patient care services from one health care facility to another and then back to the referring facility/Discharge. Essentially, the referral process has two parts. The first part begins by the referring health professional communicating relevant patient information to the receiving health professional. The second part involves the receiving health professional communicates back to the referring health professional with information and plan for continuum of care (referral feedback). And once the care is completed, the receiving unit shall return the patient back to referring unit with timely referral feedback. This system is not practiced in Mearge Hospital and uniformly. The General objectives: Assessment of factors influencing in providing referral feedback among health care provider in Mearg Hospital, in Western Zone, of Tigray Region, Northern Ethiopia . The importance of a good referral system increases the efficiency of the health system by maximizing the appropriate use of health care facilities. It strengthens the peripheral health facilities and improves the decision making capacity of professionals at the lower level of the referral network. It also creates opportunities for balanced distribution of funds, services and professionals while at the same time improving the effectiveness of the health system. In addition, a good referral system helps to promote cooperation among primary, secondary and tertiary levels of care. Methodology: A pre-post intervention study to examine percentage of patients referred to Mearg Hospital was provided with referral feedback when referred back to the referred unit or when to discharge.

description: Back ground: HIV positive individuals may or may not have desire to have children and want to use family planning. But the extent of theses desires and how it varies by individual, social, health and demographic characteristics is not well understood. Objective: The aim of this study is to assess fertility desire and family planning demand in HIV positive men and women on follow up care in Addis Ababa ARV treatment units. Method: The study was undertaken from January to February 2006, using quantitative cross-sectional study supplemented by qualitative in-depth interview on a sample of 461 PLWHA on follow up care. Study subjects were selected using stratified random sampling method. A pre- tested structured questionnaire was used to collect data and analyzed using spss version 11. Result: One hundred nine (44.7%)of women and 76(35.2%)of men, over all 40.2%of HIV positive individuals receiving care in Addis Ababa desired to have children. Generally HIV positive individuals who desired children are younger (18-29) (adjusted OR: 3.05, 95%CI: 1.5-6.4), married/in relation ship(adjusted OR :3.4,95%CI :2.1-5.6 ), have no children(adjusted OR: 11.5 ,95%CI :5.3- 24.9)and had partner who also desire children (adjusted OR: 38.7, 95%CI: 16.7- 89.1)than those who do not desire children. Two hundred forty six (53.5%) HIV positive individuals are using and 85(39.7) want to use family planning in the future. Condom was the preferred method of family planning among HIV positive individuals after HIV diagnosis. . Conclusion: A high proportion of HIV positive individuals who received medical care expressed a wish for parenthood and wants to use family planning. The extent of fertility desire and family planning needs of these people has implication for vertical, heterosexual transmission and the need for counseling. vii In view of their wishes for children and family planning it is important for care providers to address such issue. Care providers should also desist from the conventional systematic advise against pregnancy but in addition to laying emphasis on the risk, provide adequate information on available practicable reproductive option for HIV positive individuals

description: Recent studies of galaxies in the local Universe, including those in the Local Group, find that the efficiency of environmental (or satellite) quenching increases dramatically at satellite stellar masses below ~ $10^8\ {\rm M}_{\odot}$. This suggests a physical scale where quenching transitions from a slow "starvation" mode to a rapid "stripping" mode at low masses. We investigate the plausibility of this scenario using observed HI surface density profiles for a sample of 66 nearby galaxies as inputs to analytic calculations of ram-pressure and viscous stripping. Across a broad range of host properties, we find that stripping becomes increasingly effective at $M_{*} < 10^{8-9}\ {\rm M}_{\odot}$, reproducing the critical mass scale observed. However, for canonical values of the circumgalactic medium density ($n_{\rm halo} < 10^{-3.5}$ ${\rm cm}^{-3}$), we find that stripping is not fully effective; infalling satellites are, on average, stripped of < 40 - 70% of their cold gas reservoir, which is insufficient to match observations. By including a host halo gas distribution that is clumpy and therefore contains regions of higher density, we are able to reproduce the observed HI gas fractions (and thus the high quenched fraction and short quenching timescale) of Local Group satellites, suggesting that a host halo with clumpy gas may be crucial for quenching low-mass systems in Local Group-like (and more massive) host halos.
