description: Abstract
The principal environmental problem in Ethiopia is land degradation in the form of severe soil erosion, gully formation and soil fertility loss. To overcome this problem, promoting appropriate land management technologies are best options. However, farmers’ decisions to use land management practices are determined by complex factor. Thus, this study was conducted in Gindara watershed with the objective of analyzing the status of farmers’ choice of improved land management practices and investigating determinants of farmers’ decisions to use improved land management practices.

description: We have developed a pair-potential approach for the evaluation of van der Waals interaction between carbon nanotubes in bundles. Starting from a continuum model, we show that the intertube modes range from $5 cm^{-1}$ to $60 cm^{-1}$. Using a non-orthogonal tight-binding approximation for describing the covalent intra-tube bonding in addition, we confirme a slight chiral dependance of the breathing mode frequency and we found that this breathing mode frequency increase by $\sim$ 10 % if the nanotube lie inside a bundle as compared to the isolated tube.

description: We develop an analytic formalism for computing the merger rate of primordial black hole binaries with a general mass function by taking into account the torques by the surrounding primordial black holes and linear density perturbations. We find that $α=-(m_{i}+m_{j})^2\partial^{2} \ln {\mathcal R}(m_{i},m_{j})/\partial m_{i} \partial m_{j}=36/37$ is independent of the mass function. Moreover, the ratio of the merger rate density of primordial black hole binaries by taking into account the torques by the surrounding primordial black holes to by the nearest primordial black hole is independent of the masses of binaries.

We study the relations between algebro-geometric properties of the singular set of singular holomorphic distributions and their associated sheaves. We characterize either distributions whose tangent sheaf or conormal sheaf are arithmetically Cohen Macaulay (aCM) on smooth weighted projective complete intersection Fano manifolds threefold. We also prove that a codimension one locally free distribution with trivial canonical bundle on any Fano threefold, with Picard number equal to one, has a tangent sheaf which either splits or it is stable.

The Spillover Effect of Ethnic Heterogeneity on Per-Pupil Expenditures

description: In this study, I estimate the spillover effect of increased ethnic heterogeneity on per-pupil spending using a three-year panel of United States school districts. While there is general consensus that higher ethnic heterogeneity decreases public good provision, there is little research on the potential spillover effects of increased ethnic heterogeneity on public good provision. The focus is on two measures of ethnic heterogeneity: the fragmentation in-dex and the polarization index. Both of these indices disaggregate ethnic groups, which is an improvement over studies that use the share of the population that is not White as a proxy for racial mix. Both of these measures better reflect the tension that arises with local public good provision (Alesina, Baqir, and Easterly, 1999; Ajilore and Smith, 2011). In addition to using more appropriate measures of ethnic heterogeneity, this paper makes a contribution through the proper calculation of spillover effects from spatial models. The findings show greater ethnic heterogeneity has negative spillover effects on per-pupil expenditures. The public finance implications of these demographic changes are important since there will be not only increases in ethnic heterogeneity but also the geographic distribution of this heterogeneity.

description: Scalar-tensor theories of gravity where a new scalar degree of freedom couples to the Gauss-Bonnet invariant can exhibit the phenomenon of spontaneous black hole scalarization. These theories admit both the classic black holes predicted by general relativity as well as novel hairy black hole solutions. The stability of the hairy black holes is strongly dependent on the precise form of the scalar-gravity coupling. A radial stability investigation revealed that all scalarized black hole solutions are unstable when the coupling between the scalar field and the Gauss-Bonnet invariant is quadratic in the scalar, whereas stable solutions exist for exponential couplings. Here we elucidate this behavior. We demonstrate that, while the quadratic term controls the onset of the tachyonic instability that gives rise to the black hole hair, the higher-order coupling terms control the nonlinearities that quench that instability, and hence also control the stability of the hairy black hole solutions.

description: Strongly coupled supersymmetric theories can give rise to composite quarks and leptons at low energy. We show that the internal structure of these particles can explain the origin of three generations and provide a qualitative understanding of mass ratios and mixing angles between the different flavors of fermions, all within a renormalizable theory. The main point of the paper is to show how fermion masses and mixing angles can result from a ``dual'' Frogatt-Nielsen mechanism: fields neutral under $SU(3) \times SU(2) \times U(1)$ which carry flavor quantum numbers are confined within quarks and leptons, and from their perturbative interactions arises the observed flavor structure.

Pain

description: Chronic pain affects 116 million people, a number larger than the total affected by cardiovascular disease, cancer, and diabetes combined. Currently there is not a singular treatment known to provide relief from chronic pain, and the treatments that do exist are not effective for all. Novel ways to effectively treat chronic pain are needed. Laughter has been known to provide a multitude of health benefits, however it is not universally accepted as a treatment for pain. The purpose of this study was to investigate if laughter provided by comic relief can influence pain tolerance and muscle soreness compared to an uninteresting documentary. Forty, young and healthy participants were recruited from the University of Texas at Austin and underwent a randomized cross-over experiment. Each participant was exposed to a comedy video eliciting laughter as well as a documentary after inducing delayed onset muscle soreness in one leg at a time. Pain tolerance was tested on each participants’ leg before and after the videos. An interaction of time and treatment was found to be significant in a mixed model: after watching the documentary video participants’ pain tolerance was decreased by 13.3 N compared to the comedy. Pain tolerance in the sore leg was decreased by 17.3± 5.0 N after viewing the documentary video, but did not change after watching the comedy. Similar results were seen in the control leg (p

The effective two-dimensional Heisenberg Hamiltonian was constructed and used to estimate magnon dispersion laws, spin-wave stiffness constants, and overlayer Curie temperatures within the mean-field and random-phase approximations. Overlayer Curie temperature oscillates as a function of the cap-layer thickness in a qualitative agreement with a recent experiment.

description: The results of tunnelling studies of the energy spectrum of two-dimensional (2D) states in a surface quantum well in a semiconductor with inverted band structure are presented. The energy dependence of quasimomentum of the 2D states over a wide energy range is obtained from the analysis of tunnelling conductivity oscillations in a quantizing magnetic field. The spin-orbit splitting of the energy spectrum of 2D states, due to inversion asymmetry of the surface quantum well, and the broadening of 2D states at the energies, when they are in resonance with the heavy hole valence band, are investigated in structures with different strength of the surface quantum well. A quantitative analysis is carried out within the framework of the Kane model of the energy spectrum. The theoretical results are in good agreement with the tunnelling spectroscopy data.

Steady-state kinetic temperature distribution in a two-dimensional square harmonic scalar lattice lying in a viscous environment and subjected to a point heat source

description: We consider heat transfer in an infinite two-dimensional square harmonic scalar lattice lying in a viscous environment and subjected to a heat source. The basic equations for the particles of the lattice are stated in the form of a system of stochastic ordinary differential equations. We perform a continualization procedure and derive an infinite system of linear partial differential equations for covariance variables. The most important results of the paper are the deterministic differential-difference equation describing non-stationary heat propagation in the lattice and the analytical formula in the integral form for its steady-state solution describing kinetic temperature distribution caused by a point heat source of a constant intensity. The comparison between numerical solution of stochastic equations and obtained analytical solution demonstrates a very good agreement everywhere except for the main diagonals of the lattice (with respect to the point source position), where the analytical solution is singular.

description: In this paper, we present a scheme to investigate the opacity of the Universe in a cosmological-model-independent way, with the combination of current and future available data in gravitational wave (GW) and electromagnetic (EM) domain. In the FLRW metric, GWs propagate freely through a perfect fluid without any absorption and dissipation, which provides a distance measurement unaffected by the cosmic opacity. Focusing on the simulated data of gravitational waves from the third-generation gravitational wave detector (the Einstein Telescope, ET), as well as the newly-compiled SNe Ia data (JLA and Pantheon sample), we find an almost transparent universe is strongly favored at much higher redshifts ($z\sim 2.26$). Our results suggest that, although the tests of cosmic opacity are not significantly sensitive to its parametrization, a strong degeneracy between the cosmic opacity parameter and the absolute \textit{B}-band magnitude of SNe Ia is revealed in this analysis. More importantly, we obtain that future measurements of the luminosity distances of gravitational waves sources will be much more competitive than the current analyses, which makes it expectable more vigorous and convincing constraints on the cosmic opacity (and consequently on background physical mechanisms) and a deeper understanding of the intrinsic properties of type Ia supernovae in a cosmological-model-independent way.

description: Torsion pendulums have been widely used in physical experiments, because their small restoring forces are suitable for tiny force measurement. Recently, some applications such as low-frequency gravity gradiometers have been proposed by focusing on their low resonant frequencies. Torsion pendulums with low resonant frequencies enable the suspended masses to be isolated from the ground, allowing for good response to the fluctuation of local gravity field at low frequencies. However, translational ground vibration can be transferred to the horizontal rotation of the torsion pendulum nonlinearly. This effect can have a non-negligible contribution to the sensitivity of torsion pendulums as gravity gradiometers. This paper evaluates the amount of nonlinear vibration noise, and discusses how to reduce it.
Effect on the electron EDM due to abelian gauginos in SUSY extra U(1) models

description: The electric dipole moment of an electron (EDME) is investigated in the supersymmetric extra U(1) models. Neutralino sector is generally extended in these models and then the neutralino contribution will be important for the analysis of the EDME. Kinetic term mixings of abelian gauginos are taken into account in our analysis. Numerical results for the extra U(1) models show that the EDME can be affected by the extra U(1) in a certain range of soft supersymmetry breaking parameters even if the extra U(1) gauge boson is heavy. The EDME may be a clue to find an extended gauge structure in the supersymmetric models.

description: In systems with local gauge symmetries, the memory effect corresponds to traces inscribed on a suitable probe when a pure gauge configuration at infinite past dynamically evolves to another pure gauge configuration at infinite future. In this work, we study the memory effect of 2-form gauge fields which is probed by strings. We discuss the "string memory effect" for closed and open strings at classical and quantum levels. The closed string memory is encoded in the internal excited modes of the string, and in the open string case, it is encoded in the relative position of the two endpoints and the noncommutativity parameter associated with the D-brane where the open string endpoints are attached. We also discuss 2-form memory with D-brane probes using boundary state formulation and, the relation between string memory and 2-form soft charges analyzed in [1].

While the low lying electronic excitations in the doped system are well described by a modified $t-J$ model, the excitonic states of the insulator include hybrid $d_{xy}-$ $p_π$ states of $A_{2g}$ symmetry. We also obtain excitons of symmetries $B_{1g}$ and $E_u$, and eventually $A_{1g}$, which can be explained within a one-band model. The results agree with observed optical absorption and Raman excitations.

The space of ultrafunctions can be used as a richer framework for a description of a physical system in quantum mechanics. In this paper, we provide a discussion of the space of ultrafunctions and its advantages in the applications of quantum mechanics, particularly for the Schrödinger equation for a Hamiltonian with the delta function potential.

description: Svalbard is transitioning from coal mining to an economy of tourism, research and higher education. The changes are driven by the Norwegian national Svalbard policy, with environmental protection and a stable Norwegian population in Longyearbyen as overall goals.
Based on interviews with local tourism actors and authorities, and analyses of key policies we identify the dominant narratives shaping responses to policy and environmental changes and what Svalbard is and should be. The narratives range from playground to wilderness, from sustainable tourism and zero emission society to policy ambitions for strict nature conservation of this Arctic wilderness.
What Svalbard's wilderness is, and how to maintain and protect it, remains a contested issue. Potential conflicts and different levels of feasibility of national policy for tourism development in the context of changing environmental, political and economic conditions emerge.
We explore how an adaptive co-management approach to tourism has the potential to reconcile stated national policy with local tourism opportunities and community development.

Using a quantum Monte Carlo method and an exact diagonalization method, we study bond-impurity effect in the uniform $S=1/2$ chain and also in the bond-alternating chain. Here `bond impurity' means a bond with strength different from those in the bulk or a defect in the alternating order. Local magnetic structures induced by bond impurities are investigated both in the ground state and at finite temperatures, calculating the local magnetization, the local susceptibility and the local field susceptibility. We also investigate the force acting between bond impurities and find the force generally attractive.

description: This work focuses on the characterization of current spacecraft thermal protection materials, including experimental and model uncertainties. The catalysis phenomena affecting re-usable heat shield materials is considered in the physical model through a parameter that represents the exothermic recombination of atoms taking place at the material surface. Uncertainty distributions of this recombination parameter are obtained by means of a Bayesian inference framework where the model parameter is inferred from experimental data generated in a plasma wind tunnel. The testing methodology developed confirms to be a reliable experimental approach for characterizing the material and the enthalpy of the flow.

description: Few bacteria are resistant to tetracycline and can even biodegrade tetracycline in the environment. In this study, we isolated a bacterium Pandoraea sp. XY-2, which could biodegrade 74% tetracycline at pH 7.0 and 30°C within 6 days. Thereafter, we determined the whole genome sequence of Pandoraea sp. XY-2 genome is a single circular chromosome of 5.06 Mb in size. Genomic annotation showed that two AA6 family members-encoding genes and nine glutathione S-transferase (GSTs)-encoding genes could be relevant to tetracycline biodegradation. In addition, the average nucleotide identities (ANI) analysis between the genomes of Pandoraea sp. XY-2 and other Pandoraea spp. revealed that Pandoraea sp. XY-2 belongs to a new species. Moreover, comparative genome analysis of 36 Pandoraea strains identified the pan and specific genes, numerous single nucleotide polymorphisms (SNPs), insertions, and deletion variations (InDels) and different syntenial relationships in the genome of Pandoraea sp. XY-2. Finally, the evolution and the origin analysis of genes related to tetracycline resistance revealed that the six tetA(48) genes and two specific genes tetG and tetR in Pandoraea sp. XY-2 were acquired by horizontal gene transfer (HGT) events from sources related to Paraburkholderia, Burkholderia, Caballeronia, Salmonella, Vibrio, Proteobacteria, Pseudomonas, Acinetobacter, Flavimaricola and some unidentified sources. As a new spicies, Pandoraea sp. XY-2 will be an excellent resource for the bioremediation of tetracycline-contaminated environment.

description: We have obtained three-dimensional maps of the universe in $\sim200\times200\times80$ comoving Mpc$^3$ (cMpc$^3$) volumes each at $z=5.7$ and $6.6$ based on a spectroscopic sample of 179 galaxies that achieves $\gtrsim80$\% completeness down to the Ly$α$ luminosity of $\log(L_{\rm Lyα}/[\mathrm{erg\ s^{-1}}])=43.0$, based on our Keck and Gemini observations and the literature. The maps reveal filamentary large-scale structures and two remarkable overdensities made out of at least 44 and 12 galaxies at $z=5.692$ (z57OD) and $z=6.585$ (z66OD), respectively, making z66OD the most distant overdensity spectroscopically confirmed to date with $>10$ spectroscopically confirmed galaxies. We compare spatial distributions of submillimeter galaxies at $z\simeq 4-6$ with our $z=5.7$ galaxies forming the large-scale structures, and detect a $99.97\%$ signal of cross correlation, indicative of a clear coincidence of dusty star-forming galaxy and dust unobscured galaxy formation at this early epoch. The galaxies in z57OD and z66OD are actively forming stars with star formation rates (SFRs) $\gtrsim5$ times higher than the main sequence, and particularly the SFR density in z57OD is 10 times higher than the cosmic average at the redshift (a.k.a. the Madau-Lilly plot). Comparisons with numerical simulations suggest that z57OD and z66OD are protoclusters that are progenitors of the present-day clusters with halo masses of $\sim10^{14}\ \mathrm{M_\odot}$.

description: There exist an infinite number of exact small momentum fraction-$x$ boundary conditions on light-cone wavefunctions of bound states in gauge theory. They are necessary for finite expectation values of the invariant mass operator and relate components of the wavefunction from different Fock sectors. We illustrate their consequences by analyzing the small-$x$ quark Regge behavior of a heavy large-$N$ meson, finding power-law rise of unpolarized distributions. The polarized distribution changes sign and then vanishes with minus the unpolarized Regge intercept.

description: Self-testing represents the strongest form of certification of a quantum system. Here we investigate theoretically and experimentally the question of self-testing non-projective quantum measurements. That is, how can one certify, from observed data only, that an uncharacterised measurement device implements a desired non-projective positive-operator-valued-measure (POVM). We consider a prepare-and-measure scenario with a bound on the Hilbert space dimension, which we argue is natural for this problem since any measurement can be made projective by artificially increasing the Hilbert space dimension. We develop methods for (i) robustly self-testing extremal qubit POVMs (which feature either three or four outcomes), and (ii) certify that an uncharacterised qubit measurement is non-projective, or even a genuine four-outcome POVM. Our methods are robust to noise and thus applicable in practice, as we demonstrate in a photonic experiment. Specifically, we show that our experimental data implies that the implemented measurements are very close to certain ideal three and four outcome qubit POVMs, and hence non-projective. In the latter case, the data certifies a genuine four-outcome qubit POVM. Our results open interesting perspective for strong `black-box' certification of quantum devices.

description: In the framework of the Model of the Stochastic Vacuum elastic hadron-hadron scattering, photo- and electroproduction of vectormesons and also F_2(Q^2) can be well described at center of mass energy approximately 20 GeV. The scattering amplitude is derived by smearing the color dipole-dipole scattering, which is calculated nonperturbatively in the Model of the Stochastic Vacuum, with appropriate wavefunctions. For the considered processes the dipoles have extensions in the range of hadron sizes. We now extend this idea to small dipoles and high energies. The energy dependence is modeled in a phenomenological way: we assume that there a two pomerons, the soft- and the hard-pomeron, each being a simple pole in the complex angular plane. We couple dipoles of hadronic size to the soft-pomeron and small dipoles to the hard-pomeron. For small dipoles we take the perturbative gluon exchange into account. By that way we obtain an energy dependent dipole-dipole scattering amplitude which can be used for all the processes with the same parameters. We show that this approach can describe in addition to all the low energy results (20 GeV) also the HERA data for the considered processes in a large energy and Q^2 range. Especially the right transition from the soft to the hard behavior is observed.

description: Aim: To explore participation with alcohol marketing (i.e. commenting on brand statuses) and user-created promotion on social media (i.e. photos of peers drinking) by young people in the United Kingdom (UK), and what association this has with higher-risk consumption and brand identification. Method: Online cross-sectional survey with 11–19-year olds in the UK (n = 3,399) (average age: 15 years old). Past-month participation was measured for five forms of alcohol marketing on social media and one form of user-created promotion (all Yes/No). Past-month awareness of nine wider alcohol marketing activities, social media apps used at least weekly, and ownership of branded merchandise were included as covariates. Outcomes included higher-risk consumption in current drinkers (≥5 AUDIT-C) and brand identification in all respondents (8 pictures with brand names removed). Results: Over one-in-ten respondents (13.2%) had participated with at least one form of marketing on social media or participated with user-created promotion (12.2%). For both, participation was greater in current drinkers and those of legal purchasing age. A logistic regression found that participation with two or more forms of marketing on social media (AOR = 1.96, p AOR = 3.46, p SD = 2.12) alcohol brands. A linear regression found participation with marketing on social media was not associated with brand identification (β = 0.01, p = .42) but participation with user-created promotion was (β = 0.05, p Conclusion: Social media provides opportunities for adolescents to participate with commercial marketing and user-created promotion and this is associated with higher-risk consumption and brand identification.

description: We present a unified account for the coupled single-hole- and spin-dynamics in the spin-gap phase of dimerized and frustrated spin-chains and two-leg spin ladders. Based on the strong dimer-limit of a one-dimensional $t_123$-$J_123$-model a diagrammatic approach is presented which employs a mapping of the spin-Hamiltonian onto a pseudo-fermion bond-boson model. Results for the single-hole spectrum are detailed. A finite quasi-particle weight is observed and studied for a variety of system parameters. A comparison with existing exact diagonalization data is performed and good agreement is found.

description: Die vorliegende Arbeit beschäftigt sich mit der Fragestellung, wie das Internet politische Rechtsradikalisierungsprozesse von Jugendlichen beeinflussen kann. Anhand von zwei Unterfragen wird die übergeordnete Forschungsfrage operationalisiert und die leitende Forschungsheuristik der Arbeit aufgezeigt, das Zwei-Pyramiden-Modell nach McCauley und Moskalenko (2017). Zentraler Aspekt dieses Modells ist es, dass bei Radikalisierungen nicht von einer unmittelbaren Kausalität zwischen Handlung und Einstellung/Meinung ausgegangen wird, was einem weiten Radikalisierungsverständnis entspricht. Entsprechend lauten die Unterfragen: Wie kann das Internet die politische Rechtsradikalisie-rung von Haltungen und Einstellungen bei Jugendlichen beeinflussen? Wie kann das Internet die politische Rechtsradikalisierung von Handlungen und Aktionen bei Jugendlichen beeinflussen?

Zur Herleitung der Forschungsfragen werden zunächst die Kernthemen – Jugend, der digitale Raum, Rechtsextremismus/-radikalisierung und die Ausstiegs- und Distanzierungsarbeit mit rechtsaffinen und rechtsextremen Personen – dargestellt. Um soziale Prozesse zu rekonstruieren und damit das zugrundeliegende Erkenntnisinteresse dieser Arbeit darlegen zu können, wird eine qualitative Erhebung durchgeführt. Expert:inneninterviews mit Fachkräften der Ausstiegs- und Distanzierungsarbeit mit rechtsaffinen und rechtsextremen Personen erweisen sich als adäquate Erhebungsmethode. Die Interviews werden anschließend qualitativ inhaltsanalytisch ausgewertet.

Die Ergebnisse dieser Forschung machen deutlich, dass das Internet, innerhalb von Rechtsradikalisierungsprozessen von Jugendlichen eine große Bedeutung inhärent haben kann. Es können sowohl digitale Handlungen vollzogen als auch die eigene Einstellung durch digitale Inhalte beeinflusst werden. Der digitale Raum kennzeichnet sich durch seine Niedrigschwelligkeit aus und Jugendliche werden von rechtsradikalen Gruppierungen und Personen innerhalb dessen als Hauptzielgruppe adressiert. Grundlage für jeglichen Rechtsradikalisierungsprozess bilden jedoch die individuellen Prädispositionen. Somit verdeutlichen die Ergebnisse, dass der digitale Raum ein wichtiger Sozialraum sein kann, wenn junge Menschen sich in Deutschland rechtsradikalisieren. In diesem Raum muss auch professionell agiert werden, von Fachkräften der Ausstiegs- und Distanzierungsarbeit. Ein Mangel an personellen, finanziellen und fachlichen Ressourcen erschwert dieses jedoch stark.
