description: Very recently, for the first time, the two channels of nuclear deeply virtual Compton scattering (DVCS), the coherent and incoherent ones, have been separated by the CLAS collaboration at JLab, using a $^4$He target. The incoherent channel, which can provide a tomographic view of the bound proton and shed light on its elusive parton structure, is thoroughly analyzed here in Impulse Approximation (IA). A convolution formula for the cross sections in terms of those for the bound proton is derived. Novel scattering amplitudes for a bound moving nucleon have been obtained and used. A state-of-the-art nuclear spectral function, based on the AV18 potential, exact in the two-body part, with the recoiling system in its ground state, and modelled in the remaining contribution, with the recoiling system in an excited state, has been used. Different parametrizations of the generalized parton distributions of the struck proton have been tested. A good overall agreement with the data for the beam spin asymmetry (BSA) is obtained. It is found that the predicted conventional nuclear effects are relevant in DVCS and in the competing Bethe-Heitler mechanism, but they cancel each other to a large extent in their ratio, to which the measured asymmetry is proportional. Besides, the calculated ratio of the BSA of the bound proton to that of the free one does not describe that estimated by the experimental collaboration. This points to possible interesting effects beyond the IA analysis presented here. It is therefore clearly demonstrated that the comparison of the results of a conventional realistic approach, as the one presented here, with future precise data, has the potential to expose quark and gluon effects in nuclei. Interesting perspectives for the next measurements at high luminosity facilities, such as JLab at 12 GeV and the future EIC, are addressed.

description: We consider solutions to the Euler equations in the whole space from a certain class, which can be characterized, in particular, by finiteness of mass, total energy and momentum. We prove that for a large class of right-hand sides, including the viscous term, such solutions, no matter how smooth initially, develop a singularity within a finite time. We find a sufficient condition for the singularity formation, "the best sufficient condition", in the sense that one can explicitly construct a global in time smooth solution for which this condition is not satisfied "arbitrary little". Also compactly supported perturbation of nontrivial constant state is considered. We generalize the known theorem by Sideris on initial data resulting in singularities. Finally, we investigate the influence of frictional damping and rotation on the singularity formation.

description: A digraph D=(V,A) is mediated if, for each pair x,y of distinct vertices of D, either xy belongs to A or yx belongs to A or there is a vertex z such that both xz,yz belong to A. For a digraph D, DELTA(D) is the maximum in-degree of a vertex in D. The "nth mediation number" mu(n) is the minimum of DELTA(D) over all mediated digraphs on n vertices. Mediated digraphs and mu(n) are of interest in the study of quantum nonlocality. We obtain a lower bound f(n) for mu(n) and determine infinite sequences of values of n for which mu(n)=f(n) and mu(n)>f(n), respectively. We derive upper bounds for mu(n) and prove that mu(n)=f(n)(1+o(1)). We conjecture that there is a constant c such that mu(n)=

description: Binary stars have been shown to have a substantial impact on the integrated light of stellar populations, particularly at low metallicity and early ages - conditions prevalent in the distant Universe. But the fraction of stars in stellar multiples as a function of mass, their likely initial periods and distribution of mass ratios are all known empirically from observations only in the local Universe. Each has associated uncertainties. We explore the impact of these uncertainties in binary parameters on the properties of integrated stellar populations, considering which properties and timescales are most susceptible to uncertainty introduced by binary fractions and whether observations of the integrated light might be sufficient to determine binary parameters. We conclude that the effects of uncertainty in the empirical binary parameter distributions are likely smaller than those introduced by metallicity and stellar population age uncertainties for observational data. We identify emission in the He II 1640 Angstrom emission line and continuum colour in the ultraviolet-optical as potential indicators of a high mass binary presence, although poorly constrained metallicity, dust extinction and degeneracies in plausible star formation history are likely to swamp any measurable signal.

description: We have observed several new spectral features in the fluorescence of cesium atoms implanted in the hcp phase of solid helium following laser excitation to the 6$^{2}$P states. Based on calculations of the emission spectra using semiempirical Cs-He pair potentials the newly discovered lines can be assigned to the decay of specific Cs*He$_{n}$ exciplexes: an apple-shaped Cs$(AΠ_{3/2})$He$_{2}$ and a dumbbell-shaped Cs$(AΠ_{1/2}) $He$_{n}$ exciplex with a well defined number $n$ of bound helium atoms. While the former has been observed in other enviroments, it was commonly believed that exciplexes with $n>2$ might not exist. The calculations suggest Cs$(AΠ_{1/2}) $He$_{6}$ to be the most probable candidate for that exciplex, in which the helium atoms are arranged on a ring around the waist of the dumbbell shaped electronic density distribution of the cesium atom.

subject: Former Yugoslav Republic of Macedonia

description: The undeveloped rural capital market in the Former Yugoslav Republic of Macedonia is constrained by an urban–rural development gap, with limited capacities for rural development and imperfections in the rural capital market. Among the most striking hindrances are the illegal status of a large share of agricultural buildings and other real estate in rural areas, particularly on the individual family farms that prevail in the country, and the insufficient knowledge and abilities of individual farmers in applying for credit. National, EU and other donor funds are being used to improve knowledge, skills and other human resources, and to address the illegal status of buildings and facilities. During the most recent years, government support for agricultural, rural and regional development has been introduced to promote good agricultural practices, production and economic activity in rural areas. The elimination of imperfections and improvements to the functioning of the capital market – making access to credit and funds easier, especially for small-scale family farms and for rural development – are seen as measures contributing to agriculture and more balanced rural and regional development.

description: Surfactants are not a recent invention required for new technologies, but people have been using them from the early stages of civilisation, for example, in ancient Egypt and Greece. There was no significant progress in the development of detergents for thousands of years until modern chemistry initiated the production of synthetic surfactants. Today, surfactants are present all around us and our daily life would not function as it does without them. This new book on surfactants will therefore be essential reading for those who work with surfactants.
Action in Hamiltonian Models Constructed by Yang-Baxter Equation: Entanglement and Measures of Correlation

description: By using the quantum Yang-Baxterization approach, we investigate the dynamics of quantum entanglement under the actions of different Hamiltonians on the different two-qubit input states and analyze the effects of the Yang-Baxter operations on it. During any quantum process that takes place in a noisy environment, quantum correlations display behavior that does not increase. We point out that for two-qubit systems subject to actions of different Yang-Baxter operations the loss of correlations can be mitigated by the appropriate choice of the initial states and the Yang-Baxterization process. We show that in a noisy environment it possible to create the optimal conditions for performing any quantum information task.

description: Biomechanical research has previously highlighted musculoskeletal overuse injuries of the upper extremity of long-term wheelchair use. Scientists suspect that one of the reasons is repetitive mechanical loading during wheelchair propulsion. It was proposed that optimizing wheelchair propulsion may result in lowering shoulder load, and therefore the risk of overuse injuries of the shoulder complex. This thesis describes the methodological approach used in the post-processing and analysis of a measurement series on pushrim and crank propulsion of wheelchair users. Using data from a measurement series conducted by TU Wien at 25 W and 35 W power output, the methodological approach was applied. The results of kinematic, kinetic, spirometric and electromyographic data analysis and the comparison of the two propulsion techniques confirm that the novel handle-based propulsion mechanism may be a valuable alternative for long-term wheelchair users who are suffering from joint injuries. The presented methodological approach and the developed Matlab codes generally suited the requirements in post-processing and analysis, and thus provides an applicable procedure for future measurement series.
The Fully-Differential Gluon Beam Function at NNLO

Year: 2020
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: The fully-differential beam function (dBF) is a universal ingredient in resummed predictions of hadron collider observables that probe the full kinematics of the incoming parton from each colliding proton -- the virtuality and transverse momentum as well as the light-cone momentum fraction $x$. In this paper we compute the matching coefficients between the unpolarized gluon dBF and the usual parton distribution functions (PDFs) at the two-loop order. For observables probing both the virtuality and transverse momentum of incoming gluons, our results provide the part of the NNLO singular cross section related to collinear initial-state radiation, and are required for the resummation of large logarithms through N$^3$LL. Further to this, the dBF is closely linked to the beam function appearing in a generalized version of threshold factorization, via a simple integration. By performing this integration for the two-loop gluon matching coefficients, we also obtain the corresponding quantities for the generalized threshold beam function.

Multifactorial genetics of exencephaly in the SELH/Bc mouse strain
Creators: name: Hoscheit, Julia Lynn
Publisher: name: University of British Columbia
Year: 2009

description: The SELH/Bc mouse strain, a model for multifactorial human neural tube defects, has 10-30% exencephaly depending on the maternal diet. Developmental morphological studies have found that the mesencephalon fold elevation is delayed, compared to other normal strains, in all SELH/Bc embryos and that they omit Closure 2, a normal site of initiation of closure at the mesencephalon/prosencephalon boundary during cranial neural tube closure. Previous studies have found the genetic exencephaly risk to be due to a combination of three genes, Exen1, Exen2, and Exen3, acting additively. Exen1 and Exen2 had been mapped to regions on Chr 13 and Chr 5, respectively, and Exen3 provisionally to Chr 11. My studies further investigated the genetic cause of this defect using F2 exencephaly panels and congenic lines, as well as the diet effect that is observed in SELH/Bc. The frequencies of exencephaly were observed in F2 segregants from crosses between SELH/Bc and a normal unrelated strain, LM/Bc. There were two F2 exencephaly panels collected, one from mice fed the regular diet Purina Laboratory Rodent Diet #5001 and one from mice fed the high-risk diet Purina Mouse Diet #5015 ("PMD #5015") that increases exencephaly frequency in SELH/Bc. There was a significant increase in exencephaly frequency in the F2 embryos when mice were fed PMD #5015 and genotypes of the F2 ex encephalic embryos from both panels supported the hypothesis that there is gene-diet interaction between the Exen1 alleles from SELH/Bc and PMD #5015. A new locus on Chr 7 that contributed to the risk of exencephaly in the F2 embryos, named Exen4, was established as well. The congenic lines that had been created by transferring the normal Exen1 and Exen2 alleles from LM/Bc into the SELH/Bc background and the Exen1 and Exen2 alleles from SELH/Bc into the LM/Bc background confirmed the locations of the Exenl and Exen2 loci, and demonstrated that exencephaly in SELH/Bc is a multifactorial threshold trait. The congenic lines with Exen1 alleles from SELH/Bc responded to PMD #5015 supporting the hypothesis of a gene-diet interaction. Morphological studies of the cranial neural tube closure patterns in congenic line embryos supported the hypothesis that the liability trait for exencephaly (multifactorial threshold defect) is timing of mesencephalon fold elevation as the congenic line embryos showed detectable delay or acceleration of elevation of mesencephalon folds compared to their respective parental strain.

description: The energy spectrum of superfluid turbulence is studied numerically by solving the Gross-Pitaevskii equation. We introduce the dissipation term which works only in the scale smaller than the healing length, to remove short wavelength excitations which may hinder the cascade process of quantized vortices in the inertial range. The obtained energy spectrum is consistent with the Kolmogorov law.

description: Exploiting the data from the GAs Stripping Phenomena in galaxies with MUSE (GASP) survey, we study the gas-phase metallicity scaling relations of a sample of 29 cluster galaxies undergoing ram-pressure stripping and of a reference sample of (16 cluster and 16 field) galaxies with no significant signs of gas disturbance. We adopt the PYQZ code to infer the mean gas metallicity at the effective radius and achieve a well-defined mass-metallicity relation (MZR) in the stellar mass range $10^{9.25}\le M_\star \le 10^{11.5}\,{\rm M_\odot}$ with a scatter of 0.12 dex. At any given mass, reference cluster and stripping galaxies have similar metallicities, while the field galaxies with $M_\star < 10^{10.25}\,{\rm M_\odot}$ show on average lower gas metallicity than galaxies in clusters. Our results indicate that at the effective radius the chemical properties of the stripping galaxies are independent of the ram-pressure stripping mechanism. Nonetheless, at the lowest masses we detect 4 stripping galaxies well above the common MZR that suggest a more complex scenario. Overall, we find signs of an anti-correlation between the metallicity and both the star formation rate and the galaxy size, in agreement with previous studies. No significant trends are instead found with the halo mass, clustercentric distance and local galaxy density in clusters. In conclusion, we advise a more detailed analysis of the spatially resolved gas metallicity maps of the galaxies, able to highlight effects of gas redistribution inside the disk due to the ram-pressure stripping.

description: A pure two-body problem has seven integrals including the Kepler energy, the Laplace vector, and the angular momentum vector. However, only five of them are independent. When the five independent integrals are preserved, the two other dependent integrals are naturally preserved from a theoretical viewpoint; but they may not be either from a numerical computational viewpoint. Because of this, we use seven scale factors to adjust the integrated positions and velocities so that the adjusted solutions strictly satisfy the seven constraints. Noticing the existence of the two dependent integrals, we adopt the Newton iterative method combined with the singular value decomposition to calculate these factors. This correction scheme can be applied to perturbed two-body and N-body problems in the solar system. In this case, the seven quantities of each planet slowly vary with time. More accurate values can be given to the seven slowly-varying quantities by integrating the integral invariant relations of these quantities and the equations of motion. They should be satisfied with the adjusted solutions. Numerical tests show that the new method can significantly reduce the rapid growth of numerical errors of all orbital elements.

description: Terahertz (THz)-driven acceleration has recently emerged as a new route for delivering ultrashort bright electron beams efficiently, reliably, and in a compact setup. Many THz-driven acceleration related working schemes and key technologies have been successfully demonstrated and are continuously being improved to new limits. However, the achieved acceleration gradient and energy gain remain low, and the potential physics and technical challenges in the high field and high energy regime are still under-explored. Here we report a record energy gain of 170 keV in a single-stage configuration, and demonstrate the first cascaded acceleration of a relativistic beam with a 204 keV energy gain in a two-stages setup. Whole-bunch acceleration is accomplished with an average accelerating gradient of 85 MV/m and a peak THz electric field of 1.1 GV/m. This proof-of-principle result is a crucial advance in THz-driven acceleration with a major impact on future electron sources and related scientific discoveries.

Using explicit formulas describing the interaction of two solitons on a thin vortex filament in the Localized Induction Approximation we show that an appropriate choice of the parameters of the solitons leads to large phase shifts. This result does not depend on the axial flow along the filament.

description: The spin network simulator model represents a bridge between (generalised) circuit schemes for standard quantum computation and approaches based on notions from Topological Quantum Field Theories (TQFTs). The key tool is provided by the fiber space structure underlying the model which exhibits combinatorial properties closely related to SU(2) state sum models, widely employed in discretizing TQFTs and quantum gravity in low spacetime dimensions.

description: Neutrino Self-Interactions ($ν$SI) beyond the Standard Model are an attractive possibility to soften cosmological constraints on neutrino properties and also to explain the tension in late and early time measurements of the Hubble expansion rate. The required strength of $ν$SI to explain the $4σ$ Hubble tension is in terms of a point-like effective four-fermion coupling that can be as high as $10^9\, G_F$, where $G_F$ is the Fermi constant. In this work, we show that such strong $ν$SI can cause significant effects in two-neutrino double beta decay, leading to an observable enhancement of decay rates and to spectrum distortions. We analyze self-interactions via an effective operator as well as when mediated by a light scalar. Data from observed two-neutrino double beta decay is used to constrain $ν$SI, which rules out the regime around $10^9\, G_F$.

title: A silent global change- Increased use of synthetic chemicals in the society and occurence in the water cycle

description: “A silent global change“ names a situation for what it is: a mostly overlooked environmental development with a worldwide significance. The numbers of synthetic chemical production and use have been rising now over decades, creating one of the biggest environmental hazards of modern times. On top of that, it is assumed that they eventually end up in our water cycle. Yet, a lot is still unknown about the exact dimensions of the growth, the behaviour of substances inside the ecosytem or what precise effects they may have on creatures and the environment. This paper assesses the number of chemicals that have been officially produced since the 1980s until today to evaluate the oder of magnitude we are dealing with and to compare fluctuations between year dates. Finally, there will be an analysis of the development of synthetic chemical production over time. Spatially, there is a differentiation between the European area and the rest of the world, only to compile the results and see that an equal development is happening. The data is drawn from Chemical databases of the European Chemicals Agency (ECHA) on the one, and the Chemical Abstracts Service (CAS) on the other hand and consists of substance registrations for each year, made by the producers themselves or researchers. According to these databases we can see that the amount of new substances registered each year is continuously increasing for both regional contexts. Certain years like 2010, 2013 and 2018 were exploding numerically for ECHA and everything from 2014 onwards for CAS, so it is evident that the problem of chemical increase even intensified most recently. This also includes hazardous groups like Biocides, Endocrine Disruptors and PBTs. Accordingly, literature research shows that their occurrence in our waters became an increasing problem. Judicial regulations for this matter were replaced in the 1990s and therefore should additionally be reviewed according to todays circumstances.

description: The Apollo-type near-Earth asteroid (155140) 2005 UD is thought to be a member of the Phaethon-Geminid meteor stream Complex (PGC). Its basic physical parameters are important for unveiling its origin and its relationship to the other PGC members as well as to the Geminid stream. Adopting the Lommel-Seeliger ellipsoid method and $H,G_1,G_2$ phase function, we carry out spin, shape, and phase curve inversion using the photometric data of 2005~UD. The data consists of 11 new lightcurves, 3 lightcurves downloaded from the Minor Planet Center, and 166 sparse data points downloaded from the Zwicky Transient Facility database. As a result, we derive the pole solution of ($285^\circ.8^{+1.1}_{-5.3}$, $ -25^\circ.8^{+5.3}_{-12.5}$) in the ecliptic frame of J2000.0 with the rotational period of $5.2340$ h. The corresponding triaxial shape (semiaxes $a>b>c$) is estimated as $b/a= 0.76^{+0.01}_{-0.01}$ and $c/a=0.40^{+0.03}_{-0.01}$. Using the calibrated photometric data of 2005 UD, the $H,G_1,G_2$ parameters are estimated as $17.19^{+0.10}_{-0.09}$ mag, $0.573^{+0.088}_{-0.069}$, and $0.004^{+0.020}_{-0.021}$, respectively. Correspondingly, the phase integral $q$, photometric phase coefficient $k$, and the enhancement factor $ζ$ are 0.2447, -1.9011, and 0.7344. From the values of $G_1$ and $G_2$, 2005 UD is likely to be a C-type asteroid. We estimate the equivalent diameter of 2005 UD from the new $H$-value: it is 1.30 km using the new geometric albedo of 0.14.

title: A critical analysis of the consequences of the EU-proposed ban on single-use plastic items

description: In recent years, marine litter became one of the biggest concerns. Worldwide, 9 million tonnes of mismanaged plastic waste enter the oceans every year, and the adverse effects on the environment will multiply. By proposing a new directive “on the reduction of the impact of certain plastic products on the environment” (single-use plastics) in 2018, the European Union has itself committed to combat macro plastic marine litter. The ban on certain plastic products, including cutlery and straws, enjoys the most popularity. For this reason, the masters thesis studied the impacts that the ban will have on the environment and the plastic industry. The outcome was disillusioning. Only 220 tonnes of marine litter from the banned items could have been reduced by 2030. Compared to the annual amount of 15,000 tonnes in Europe, or 9 million tonnes of mismanaged plastic waste that flows into the ocean worldwide, the 220 tonnes are neglectable. Although the reduction may be observable throughout beach counts, an assessment of the actual impact on the environment (e.g., reduction in the number of entanglements of species) is not envisaged under the proposal. Furthermore, a great resistance of the industry to the implementation of the ban is not expected. Although the impact of the ban is minimal, the overall value of the legislative proposal is not. When properly implemented and monitored, the action taken by the EU can further raise awareness, trigger more countries to act, and be the starting point of the needed international and global cooperation that is needed to combat marine litter.

description: This paper describes and analyses to what extent offshore wind energy can be used by European Union Member States to reach their renewable energy targets of 32% by 2030 and at the same time reduce their CO2 emissions by 382 Mt. It not only looks at the designs of bottom-fixed and floating offshore wind turbines but identifies the main issues that need to be addressed by the Member States of the European Union with a focus on the North Sea, which has already seen high numbers of wind farms being build, and the Baltic Sea, which has a lot of potential to offer.
title: Salt Effects on Formation and Stability of Colloidal Gas Aphrons Produced by Anionic and Zwitterionic Surfactants in Xanthan Gum Solution

description: This work is devoted to the influence of NaCl salt concentration on the formation and stability of colloidal gas aphrons (CGA) produced by the anionic surfactant sodium dodecyl sulfate (SDS) and zwitterionic surfactant coco amido propyl betaine (CAPB) in the presence of xanthan gum (XG) as a stabilizer. Dynamic surface tension measurements as well as volume and half-life time of the produced foams are considered for stability analysis. A sharp decrease of the half-life time and volume of the CGAs at NaCl concentrations larger than 20,000 ppm was observed, which was attributed to the precipitation of SDS in the solution. The mentioned SDS precipitation altered the dynamic surface tension behavior, dilational surface elasticity, and turbidity of the solution. The main reason for the precipitation of SDS is the increased Krafft point caused by the addition of salt. However, for the zwitterionic surfactant CAPB, the effects of added NaCl on the interfacial properties required for CGAs production was negligible due to the simultaneous effects on the cationic and anionic head groups in the CAPB leading to negligible changes in the net repulsion forces. Yet, an overall reduction in the half-life time of CGAs with increasing salt concentration, even when we have no precipitation, was observed for both surfactants, which could be explained by the reduction in the ability of XG to increase the viscosity with increasing salt concentration.
