description: Nicht zuletzt aufgrund der stetig wachsenden M&A - Transaktionsvolumina setzt die vorliegende Arbeit ihren Fokus insbesondere darauf, ausgewählte M&A-Finanzierungsstrukturen und deren Schranken zu analysieren. Untersucht werden vor allem die wirtschaftlichen und rechtlichen Hintergründe der Akquisitionsfinanzierung. Neben einer Skizzierung der zwingenden österreichischen Bestimmungen über die Kapitalerhaltung (§ 52 AktG, § 82 GmbHG), soll auch der aktuelle Standpunkt des OGH zur Akquisitionsfinanzierung und deren rechtliche Grenze näher durchleuchtet werden. Die vorliegende Arbeit untersucht die Frage der Zulässigkeit ausgewählter Transaktionsfinanzierungen insbesondere unter dem Blickwinkel des Verbotes der Einlagenrückgewähr. Angesichts der Tatsache, dass sich das M&A-Geschäft mit Verschmelzungen von Unternehmen sowie Unternehmenskäufen als eigener Wirtschaftszweig für Banken, Finanzdienstleister, Wirtschaftsprüfer, Steuerberater und Rechtsanwälte herauskristallisiert hat, ist eine eingehende wissenschaftliche Auseinandersetzung mit dieser Forschungsfrage vor allem auch für die Praxis von enormer Bedeutung.

description: We have performed first-principles calculations of thick slabs of Ti-doped sodium alanate (NaAlH_4), which allows to study the system energetics as the dopant progresses from the surface to the bulk. Our calculations predict that Ti stays on the surface, substitutes for Na, and attracts a large number of H atoms to its vicinity. Molecular dynamics simulations suggest that the most likely product of the Ti-doping is the formation of H-rich TiAl_n (n>1) compounds on the surface, and hint at the mechanism by which Ti enhances the reaction kinetics of NaAlH_4.

description: Air-to-ground (A2G) networks, using unmanned aerial vehicles (UAVs) as base stations to serve terrestrial user equipments (UEs), are promising for extending the spatial coverage capability in future communication systems. Coordinated transmission among multiple UAVs significantly improves network coverage and throughput compared to a single UAV transmission. However, implementing coordinated multi-point (CoMP) transmission for UAV mobility requires complex cooperation procedures, regardless of the handoff mechanism involved. This paper designs a novel CoMP transmission strategy that enables terrestrial UEs to achieve reliable and seamless connections with mobile UAVs. Specifically, a computationally efficient CoMP transmission method based on the theory of Poisson-Delaunay triangulation is developed, where an efficient subdivision search strategy for a CoMP UAV set is designed to minimize search overhead by a divide-and-conquer approach. For concrete performance evaluation, the cooperative handoff probability of the typical UE is analyzed, and the coverage probability with handoffs is derived. Simulation results demonstrate that the proposed scheme outperforms the conventional Voronoi scheme with the nearest serving UAV regarding coverage probabilities with handoffs. Moreover, each UE has a fixed and unique serving UAV set to avoid real-time dynamic UAV searching and achieve effective load balancing, significantly reducing system resource costs and enhancing network coverage performance.

Lunar scintillometer array for atmospheric turbulence measurement
Creators: name: Dumais, Marie-Andree
Publisher: name: University of British Columbia
Year: 2010

description: The performance of large telescopes is directly related to the quality of the site. Of particular importance is the turbulence profile within the lower few hundred meters of the atmosphere. We have developed a new technique for measuring this profile, and the Fried parameter r₀, by measuring spatial correlations in the scintillation of moonlight. Our lunar scintillometer array uses 12 photodiodes to measure the intensity fluctuation covariance function, and from this we obtain the index of refraction profile C²[sub N] to a height of about 200 m with a vertical resolution of order 2%. This paper describes the instrument, the technique, and results of initial tests.

description: The next generation of electron-hadron facilities has the potential for significantly improving our understanding of exotic hadrons. The XYZ states have not been seen in photon-induced reactions so far. Their observation in such processes would provide an independent confirmation of their existence and offer new insights into their internal structure. Based on the known experimental data and the well-established quarkonium and Regge phenomenology, we give estimates for the exclusive cross sections of several XYZ states. For energies near threshold we expect cross sections of few nanobarns for the Zc(3900)+ and upwards of tens of nanobarn for the X(3872), which are well within reach of new facilities.

description: This article examines the problem of area coverage for a network of mobile robots with imprecise agent localization. Each robot has uniform radial sensing ability, governed by first order kinodynamics. The convex-space is partitioned based on the Guaranteed Voronoi (GV) principle and each robot's area of responsibility corresponds to its GV-cell, bounded by hyperbolic arcs. The proposed control law is distributed, demands the positioning information about its GV-Delaunay neighbors and has an inherent collision avoidance property.

title: Synthesis of novel heterocyclic α-amino acids
Creators: name: Berthelot, Didier
Publisher: name: The Open University
Year: 2001

description: This thesis describes the incorporation of heterocycles as part of an α-amino acid side-chain. Two methods were adopted. The first involved the alkylation of a pseudoephedrine glycinamide enolate using haloalkanes. The method was validated by making the naturally occurring amino acid phenylalanine. Subsequently naphthyl-, pyridyl-, biphenyl- and isoxazolyl- groups were successfully incorporated into the amino acid side chain. The enantiomeric excess of the product amino acids was found to be moderate (10-87%) due to poor diastereoselectivity in the key alkylation step. Moreover, the strict experimental conditions required for the alkylation reaction were found to be difficult to reproduce. Attempts to apply this enolate anion strategy to the incorporation of nucleic acid bases utilising an analogous purine electrophile failed, the reaction leading only to elimination. Thus, amino acids that carry a nucleic acid base in the side chain were synthesised by an alternative method. In this, N-(2-iodoethyl)- and N-(3-iodopropyl)-pyrimidines and purines underwent stereoselective conjugate radical addition with an optically active oxazolidinone acceptor derived from (R)-S-methylcysteine to give syn-adducts. Hydrolysis of the oxazolidinone adducts followed by deprotection afforded the desired amino acids carrying pyrimidine- (thymine, uracil) and purine- (adenine, guanine) containing side chains. The enantiomeric excesses, which reflect the diastereoselectivity of the radical addition step, were found to be between 85 and 89%.

description: We examine the disc--jet connection in stellar mass and supermassive black holes by investigating the properties of their compact emission in the hard X-ray and radio bands. We compile a sample of ~100 active galactic nuclei with measured mass, 5 GHz core emission, and 2-10 keV luminosity, together with 8 galactic black holes with a total of about 50 simultaneous observations in the radio and X-ray bands. Using this sample, we study the correlations between the radio (L_R) and the X-ray (L_X) luminosity and the black hole mass (M). We find that the radio luminosity is correlated with both M and L_X, at a highly significant level. We show how this result can be used to extend the standard unification by orientation scheme to encompass unification by mass and accretion rate.

description: Adaptive traffic signal control is one key avenue for mitigating the growing consequences of traffic congestion. Incumbent solutions such as SCOOT and SCATS require regular and time-consuming calibration, can't optimise well for multiple road use modalities, and require the manual curation of many implementation plans. A recent alternative to these approaches are deep reinforcement learning algorithms, in which an agent learns how to take the most appropriate action for a given state of the system. This is guided by neural networks approximating a reward function that provides feedback to the agent regarding the performance of the actions taken, making it sensitive to the specific reward function chosen. Several authors have surveyed the reward functions used in the literature, but attributing outcome differences to reward function choice across works is problematic as there are many uncontrolled differences, as well as different outcome metrics. This paper compares the performance of agents using different reward functions in a simulation of a junction in Greater Manchester, UK, across various demand profiles, subject to real world constraints: realistic sensor inputs, controllers, calibrated demand, intergreen times and stage sequencing. The reward metrics considered are based on the time spent stopped, lost time, change in lost time, average speed, queue length, junction throughput and variations of these magnitudes. The performance of these reward functions is compared in terms of total waiting time. We find that speed maximisation resulted in the lowest average waiting times across all demand levels, displaying significantly better performance than other rewards previously introduced in the literature.

description: We study the small mass limit of the equation describing planar motion of a charged particle of a small mass $μ$ in a force field, containing a magnetic component, perturbed by a stochastic term. We regularize the problem by adding a small friction of intensity $\e>0$. We show that for all small but fixed frictions the small mass limit of $q_{μ, \e}$ gives the solution $q_\e$ to a stochastic first order equation, containing a noise-induced drift term. Then, by using a generalization of the classical averaging theorem for Hamiltonian systems by Freidlin and Wentzell, we take the limit of the slow component of the motion $q_\e$ and we prove that it converges weakly to a Markov process on the graph obtained by identifying all points in the same connected components of the level sets of the magnetic field intensity function.

description: A notable issue, the proper description of mass and charge distributions of fission fragments within nonadiabatic descriptions of fission dynamics, is investigated by performing double particle number projection on the outcomes of time-dependent Hartree-Fock (TDHF) simulation. The induced fission process of the benchmark nucleus 240Pu is studied. In the three-dimensional Cartesian coordinate without any symmetry restrictions, we get the static fission pathway from the two-dimensional potential energy surface, and then the fission dynamics from saddle to scission point are obtained using TDHF. We show that the charge numbers of primary heavy fragments from TDHF simulation strongly depend on the deformations of initial configurations via the two asymmetric fission channels, which can be distinguished according to the dynamical fission trajectories. The charge distribution of fission fragments is well reproduced using the double particle number projection technique. After applying the Gaussian kernel estimation based on the distribution from the double particle number projection technique, the mass distribution is also consistent with the experimental results. Besides, the results of the total kinetic energy of fission fragments are reasonably consistent with the experiments.

description: The recent outbreak of novel “coronavirus disease 2019” (COVID-19) has spread rapidly worldwide, causing a global pandemic. In the present work, we have elucidated the mechanism of binding of two inhibitors, namely α-ketoamide and Z31792168, to SARS-CoV-2 main protease (Mpro or 3CLpro) by using all-atom molecular dynamics simulations and free energy calculations. We calculated the total binding free energy (ΔGbind) of both inhibitors and further decomposed ΔGbind into various forces governing the complex formation using the Molecular Mechanics/Poisson-Boltzmann Surface Area (MM/PBSA) method. Our calculations reveal that α-ketoamide is more potent (ΔGbind= − 9.05 kcal/mol) compared to Z31792168 (ΔGbind= − 3.25 kcal/mol) against COVID-19 3CLpro. The increase in ΔGbind for α-ketoamide relative to Z31792168 arises due to an increase in the favorable electrostatic and van der Waals interactions between the inhibitor and 3CLpro. Further, we have identified important residues controlling the 3CLpro-ligand binding from per-residue based decomposition of the binding free energy. Finally, we have compared ΔGbind of these two inhibitors with the anti-HIV retroviral drugs, such as lopinavir and darunavir. It is observed that α-ketoamide is more potent compared to lopinavir and darunavir. In the case of lopinavir, a decrease in van der Waals interactions is responsible for the lower binding affinity compared to α-ketoamide. On the other hand, in the case of darunavir, a decrease in the favorable intermolecular electrostatic and van der Waals interactions contributes to lower affinity compared to α-ketoamide. Our study might help in designing rational anti-coronaviral drugs targeting the SARS-CoV-2 main protease. Communicated by Ramaswamy H. Sarma

description: A complete set of d+1 mutually unbiased bases exists in a Hilbert spaces of dimension d, whenever d is a power of a prime. We discuss a simple construction of d+1 disjoint classes (each one having d-1 commuting operators) such that the corresponding eigenstates form sets of unbiased bases. Such a construction works properly for prime dimension. We investigate an alternative construction in which the real numbers that label the classes are replaced by a finite field having d elements. One of these classes is diagonal, and can be mapped to cyclic operators by means of the finite Fourier transform, which allows one to understand complementarity in a similar way as for the position-momentum pair in standard quantum mechanics. The relevant examples of two and three qubits and two qutrits are discussed in detail.

description: The pandemic caused by novel coronavirus disease 2019 (COVID-19) infecting millions of populations worldwide and counting, has demanded quick and potential therapeutic strategies. Current approved drugs or molecules under clinical trials can be a good pool for repurposing through in-silico techniques to quickly identify promising drug candidates. The structural information of recently released crystal structures of main protease (Mpro) in APO and complex with inhibitors, N3, and 13b molecules was utilized to explore the binding site architecture through Molecular dynamics (MD) simulations. The stable state of Mpro was used to conduct extensive virtual screening of the aforementioned drug pool. Considering the recent success of HIV protease molecules, we also used anti-protease molecules for drug repurposing purposes. The identified top hits were further evaluated through MD simulations followed by the binding free energy calculations using MM-GBSA. Interestingly, in our screening, several promising drugs stand out as potential inhibitors of Mpro. However, based on control (N3 and 13b), we have identified six potential molecules, Leupeptin Hemisulphate, Pepstatin A, Nelfinavir, Birinapant, Lypression and Octreotide which have shown the reasonably significant MM-GBSA score. Further insight shows that the molecules form stable interactions with hot-spot residues, that are mainly conserved and can be targeted for structure- and pharmacophore-based designing. The pharmacokinetic annotations and therapeutic importance have suggested that these molecules possess drug-like properties and pave their way for in-vitro studies.

description: Nowadays, long distance optical fibre transmission systems use polarization diversity multiplexed signals to enhance transmission performance. Distributed acoustic sensors (DAS) use the same propagation medium ie. single mode optical fibre, and aims at comparable targets such as covering the highest distance with the best signal quality. In the case of sensors, a noiseless transmission enables to monitor a large quantity of mechanical events along the fibre. This paper aims at extending the perspectives of DAS systems with regard to technology breakthroughs introduced in long haul transmission systems over the last decade. We recently developed a sensor interrogation method based on coherent phase-sensitive optical time domain reflectometry ($ϕ$-OTDR), with dual polarization multiplexing at the transmitter and polarization diversity at the receiver. We name this technique Coherent-MIMO sensing. A study is performed from a dual-polarization numerical model to compare several sensor interrogation techniques, including Coherent-MIMO. We demonstrate that dual-polarization probing of a fibre sensor makes it insensitive to polarization effects, decreases the risks of false alarms and thus strongly enhances its sensitivity. The simulations results are validated with an experiment, and finally quantitative data are given on the performance increase enabled by Coherent-MIMO sensing.

description: The period since the Polish integration with the European Union has been characterized by an increase in household income of farmers and also by income diversity. The household disposable income of farmers in the area group of 20 hectares or more is about 2.0 times higher than in the 1-5 hectare group and the farm income is similarly about 2.7 times higher. However, non-farm incomes in small farms are higher than in bigger ones. One of the reasons are the area payments granted to each hectare of land in good cultivation. Small households benefited from the area payments the least. Small farms supplement low incomes from farming with income from work outside agriculture. Integration with the EU has reinforced the farm area impact on income situation of farming families and had a positive impact on the development of various forms of earnings outside agriculture. Essential for improving the social and economic situation of forming families is the development of small and medium enterprises, cooperatives and producer groups. Positive effects can also bring an implementation of rural renewal schemes. / Synopsis. Okres integracji Polski z Unią Europejską cechuje wzrost dochodów gospodarstw domowych rolników, ale także ich zróżnicowanie. Dochód rozporządzalny gospodarstw domowych rolników ogółem w grupie obszarowej 20 ha i więcej jest wyższy około 2,0 razy niż w grupie 1-5 ha, a dochód z gospodarstwa rolnego analogicznie około 2,7 razy. Natomiast w gospodarstwach małych dochody pozarolnicze są wyższe niż w dużych. Jedną z przyczyn są dopłaty obszarowe przyznawane do każdego hektara gruntów utrzymanych w dobrej kulturze. Z dopłat najmniej skorzystały gospodarstwa o małym obszarze. Gospodarstwa małe uzupełniają niskie dochody z rolnictwa dochodami z pracy pozarolniczej. Integracja z UE wzmocniła wpływ obszaru gospodarstwa na sytuację dochodową rodzin rolniczych oraz miała pozytywny wpływ na rozwój różnych form zarobkowania poza rolnictwem. Podstawowe znaczenie dla poprawy sytuacji ekonomicznej i społecznej rodzin rolniczych ma rozwój sektora małych i średnich przedsiębiorstw, spółdzielczości oraz grup producentów. Pozytywne efekty może mieć także wdrażanie programów odnowy wsi.

description: From the beginning of our membership in European Union, the development of rural areas is connected with EU policy. The EU policy is realized as Common Agricultural Policy (CAP). This year marks a new stage of implementation of this strategy (2014-2020). One of the tools of implementation of CAP is Rural Development Programme (RDP) which offers financial support to all the EU states. In Poland the new stage of implementation focuses on realization of tasks stated in “Sustainable development strategy of agriculture, rural development and fisheries”. The aim of this paper is to demonstrate a direction of development of polish rural areas which based on sustainable development using common-pool resources and social potential. The meaning of local partnerships was highlight. These partnerships are important agents which effectively realize the sustainable development goals and contribute to create a social capital in rural areas.
title: Carbon Chemistry Of Giant Impacts

description: Impact diamonds were found in several impactites from the Ries crater, Germany including fallout and fallback (crater fill) suevites. a glass bomb, impact melt rock and shocked gneiss. These diamonds formed two distinct grain size populations: 50-300?m apographitic. platy aggregates with surface ornamentation and etching that were observed using optical and scanning electron microscopy and 5-20?m diamonds which displayed two different morphologies identified using transmission electron microscopy and selected area electron diffraction. These 5-20?m grains comprised apographitic. platy grains with stacking faults, etching and graphite intergrowths together with elongate skeletal grains with preferred orientations to the individual crystallites. Thermal annealing of stacking faults and surface features was also detected. Stepped combustion combined with static mass spectrometry to give carbon isotopic analysis of individual diamonds. graphite and acid-residues indicate that the primary carbon source is graphite. This graphite was found to be 13C depleted with respect to similar samples from the Popigai impact crater. The admixture of presumably carbonate derived carbonaceous material is suggested to account for the 13C-enriched ?13C compositions encountered in whole-rock suevites known to include carbonate melts. On the basis of morphology. mineralogical associations diamond/graphite ratios and carbon isotopic compositions three possible formation mechanisms for impact diamonds are suggested: fast. high temperature conversion of graphite following the passage of the shock wave, a vapour phase condensation or growth within substrate minerals or an orientated stress field and the incomplete transformation of a mixture of amorphous and crystalline graphite. Further more exotic mechanisms such as intermediary carbyne phases cannot be discounted. Impact diamonds, 1-5?m in size. were also identified in suevite residues and a black matrix lithic breccia from the Gardnos impact crater. Norway. The carbon isotopic compositions are in agreement with previous measurements of whole rock samples with a small 13C-enriched component probably representing diamond.
Instability and spatiotemporal rheochaos in a shear-thickening fluid model

description: We model a shear-thickening fluid that combines a tendency to form inhomogeneous, shear-banded flows with a slow relaxational dynamics for fluid microstructure. The interplay between these factors gives rich dynamics, with periodic regimes (oscillating bands, travelling bands, and more complex oscillations) and spatiotemporal rheochaos. These phenomena, arising from constitutive nonlinearity not inertia, can occur even when the steady-state flow curve is monotonic. Our model also shows rheochaos in a low-dimensional truncation where sharply defined shear bands cannot form.

description: We present two classes of stars with yet unknown evolutionary phase: the B[e] supergiants and the so-called unclassified B[e] stars. While the B[e] supergiants are luminous post-main sequence stars with high mass progenitors, not much is known of the unclassified stars. We discuss how it might be possible to determine their evolutionary phases in the area of new large telescopes.

description: We report on a spectroscopic determination of the stellar parameters and chemical abundances for the parent star of the transiting planet TrES-1. Based on a detailed analysis of iron lines in our Keck and HET spectra we derive $T_\mathrm{eff} = 5250\pm 75$ K, $\log g = 4.6\pm 0.2$, and [Fe/H] $= 0.00\pm 0.09$. By measuring the \ion{Ca}{2} activity indicator and by putting useful upper limits on the Li abundance we constrain the age of TrES-1 to be $2.5\pm 1.5$ Gyr. By comparing theoretical stellar evolution models with the observational parameters we obtain $M_\star = 0.89\pm 0.05$ $M_\odot$, and $R_\star = 0.83\pm 0.05$ $R_\odot$. Our improved estimates of the stellar parameters are utilized in a new analysis of the transit photometry of TrES-1 to derive a mass $M_p = 0.76\pm 0.05$ $M_\mathrm{J}$, a radius $R_p = 1.04^{+0.08}_{-0.05}$ $R_\mathrm{J}$, and an inclination $i = 89^\circ.5^{+0.5}_{-1.3}$. The improved planetary mass and radius estimates provide the grounds for new crucial tests of theoretical models of evolution and evaporation of irradiated extrasolar giant planets.

title: Magnetoencephalographic studies of neural systems associated with higher order processes in humans
Creators: name: Bräutigam, Sven
Publisher: name: The Open University
Year: 1998

description: This thesis has been concerned with the neuromagnetic fields associated with the processing of faces and sentences in humans. In four, largely independent sub-projects, results were obtained using novel methods of analysis to extract neurophysiologically relevant information from magnetoencephalographic MEG readings. Using the MEG facility of the Helsinki University of Technology, Finland, the research has led to four main suggestions: a) there are early latency face-specific neural systems in humans that are predominantly in right inferior occipito-temporal cortex, b) MEG recordings are useful in the study of autism, in that autistic subjects exhibit different responses to normal subjects following face presentation, c) phase-locked y-band activity has a specific role in semantic processing of sentences in normal subjects, and d) the late components of responses to face images are modified by endogenous priming, which is detectable before stimulus arrival in normal subjects. In order to pursue these neuroscience objectives, new methods for treating MEG data were developed, implemented and used. These comprise: a) an improved parameterisation of signal power over regions of interest, b) the use of re-sampling strategies to achieve statistical assessment of spectral coefficients within subjects, and c) a prestimulus method for the study of face processing using a tailored state-space representation approach.
