description: This paper presents a novel adaptive reduced-rank {multi-input multi-output} (MIMO) equalization scheme and algorithms based on alternating optimization design techniques for MIMO spatial multiplexing systems. The proposed reduced-rank equalization structure consists of a joint iterative optimization of two equalization stages, namely, a transformation matrix that performs dimensionality reduction and a reduced-rank estimator that retrieves the desired transmitted symbol. The proposed reduced-rank architecture is incorporated into an equalization structure that allows both decision feedback and linear schemes for mitigating the inter-antenna and inter-symbol interference. We develop alternating least squares (LS) expressions for the design of the transformation matrix and the reduced-rank estimator along with computationally efficient alternating recursive least squares (RLS) adaptive estimation algorithms. We then present an algorithm for automatically adjusting the model order of the proposed scheme. An analysis of the LS algorithms is carried out along with sufficient conditions for convergence and a proof of convergence of the proposed algorithms to the reduced-rank Wiener filter. Simulations show that the proposed equalization algorithms outperform the existing reduced-rank and full-rank algorithms, while requiring a comparable computational cost.

description: Spreading processes represent a very efficient tool to investigate the structural properties of networks and the relative importance of their constituents, and have been widely used to this aim in static networks. Here we consider simple disease spreading processes on empirical time-varying networks of contacts between individuals, and compare the effect of several immunization strategies on these processes. An immunization strategy is defined as the choice of a set of nodes (individuals) who cannot catch nor transmit the disease. This choice is performed according to a certain ranking of the nodes of the contact network. We consider various ranking strategies, focusing in particular on the role of the training window during which the nodes' properties are measured in the time-varying network: longer training windows correspond to a larger amount of information collected and could be expected to result in better performances of the immunization strategies. We find instead an unexpected saturation in the efficiency of strategies based on nodes' characteristics when the length of the training window is increased, showing that a limited amount of information on the contact patterns is sufficient to design efficient immunization strategies. This finding is balanced by the large variations of the contact patterns, which strongly alter the importance of nodes from one period to the next and therefore significantly limit the efficiency of any strategy based on an importance ranking of nodes. We also observe that the efficiency of strategies that include an element of randomness and are based on temporally local information do not perform as well but are largely independent on the amount of information available.

description: The belemnite species Hibolites jaculoides Swinnerton, 1937 is redefined on the basis of a bed by bed collection of 2100 rostrums from the Upper Hauterivian (Cretaceous deposits of NW Germany and Yorkshire, England. According to the variate-statistical evaluation of the data gathered, definite phylotic changes are disdernible within the species. All characters measured indicate a definite tendency towards reduction in size. Large-sized, club-shaped specimens are typical for the stratigraphically older beds, delicate and slender-built forms dominate in the upper Upper Hauterivian. Comparison of the material from England and Germany yielded that three of the varieties described by Swinnerton are limited mainly to the lower Upper Hauterivian of England.
description: Anhand von 2100 zumeist horizontiert gesammelten Rostren aus dem Ober-Hauterivium von NW-Deutschland und Yorkshire/England wird die Belemnitenart Hibolites jaculoides SWINNERTON, 1937 neu untersucht. Wie die variationsstatistische Auswertung des Materials zeigt, unterliegt die Art im Laufe der Phylogenie einer gerichteten Entwicklung. Alle vermessenen Merkmale zeigen eine deutliche Tendenz zur Verkleinerung ihrer Werte. Für die stratigraphisch älteren Bereiche sind großwüchsige, deutlich keulenförmige Exemplare typisch, im höheren Ober-Hauterivium überwiegen schlanke, zierliche Formen. Aus einem Vergleich des englischen und deutschen Materials ergibt sich, daß die 3 von SWINNERTON aufgestellten Variationen im wesentlichen auf das tiefe Ober-Hauterivium von England beschränkt sind.

description: High temperature superconductivity emerges in unique materials, like cuprates, that belong to the class of heterostructures at atomic limit, made of a superlattice of superconducting atomic layers intercalated by spacer layers. The physical properties of a strongly correlated electronic system, emerge from the competition between different phases with a resulting inhomogeneity from nanoscale to micron scale. Here we focus on the spatial arrangements of two types of structural defects in the cuprate La2CuO4+y : i) the local lattice distortions in the CuO2 active layers and ii) the lattice distortions around the charged chemical dopants in the spacer layers. We use a new advanced microscopy method: scanning nano X-ray diffraction (nXRD). We show here that local lattice distortions form incommensurate nanoscale ripples spatially anticorrelated with puddles of self-organized chemical dopants in the spacer layers.

description: Apple replant disease (ARD) occurs when apple is repeatedly planted at the same site, leading to growth reductions and losses in fruit yield and quality. Up to now, the etiology has been poorly understood; however, soil (micro)biota are known to be involved. Because endophytes often colonize plants via the rhizosphere, this study aimed at comparing the bacterial endophytic root microbiome in plants growing in ARD-affected and unaffected soils from three different sites based on greenhouse biotests using a molecular barcoding approach. The initial endophytic microbiome of the starting material (in vitro propagated plants of the apple rootstock M26) did not significantly affect the overall richness and diversity of the endophytic community in plants after 8 weeks of growth in the respective soils but some genera of the initial microbiome managed to establish in apple roots. Proteobacteria was the dominant phylum in all samples. No differences in diversity or number of amplicon sequence variants (ASVs) between plants grown in ARD soil and unaffected soil was observed. However, several ASVs of high abundance uniquely found in plants grown in ARD-affected soils were Streptomyces spp. In soil from all three sites, these Streptomyces spp. were negatively correlated with plant growth parameters. Future inoculation experiments using selected Streptomyces isolates have to prove whether bacteria from this genus are opportunists or part of the ARD complex. For the first time, the bacterial endophytic community of apple roots grown in ARD-affected soils was characterized, which will help us to understand the etiology of ARD and develop countermeasures.
title:    Network analysis of international patent data: technology cohort, temporal dynamics and the role of trade
Creators: name: Gao, Yuan
Publisher: name: IMT Alti Studi Lucca

description: Access to online electronic database and international patent
 data harmonization has enabled more researchers to work
 with patent data. This thesis joins the more recent studies
 to apply network methodologies to patent data analysis in
 order to understand the multi-variable interactions in innovation, knowledge flows, and technological trends.
 The first chapter focuses on technology cohort in the patent
 family networks and citation networks to investigate how technologies are integrated in utility invention and the patterns
 over time. The consistent technological groups found in this
 analysis are compared to the authority-defined system and
 provide a more complete coverage.
 Chapter 2 focuses on community evolution over time. The
 stabilized Louvain method is adopted to improve consistency
 and stability of community detection. The majority mapping
 algorithm is incorporated for community tracking across time
 slices. A new method is developed to identify sets of central
 nodes. A case study of patent filed by applicants in Germany
 is used to demonstrate and verify the method and the results.
 In the last chapter, I apply the methods developed from the
 first two chapters to the pharmaceutical sector. Motivated
 by the needs to encourage pharmaceutical R&D and promote
 globalized innovation, I focus on the effects of being central
 with a favorable balance in international market on being central in global pharmaceutical R&D collaboration. The descriptive results and a further regression analysis shows positive
 effects from export “Coreness” on co-invention centrality. Despite causality is not fully resolved, our results show a fundamental relationship between knowledge production and
 trade in pharmaceuticals.

description: In this work, we are concerned with neural network guided goal-oriented a posteriori error estimation and adaptivity using the dual weighted residual method. The primal problem is solved using classical Galerkin finite elements. The adjoint problem is solved in strong form with a feedforward neural network using two or three hidden layers. The main objective of our approach is to explore alternatives for solving the adjoint problem with greater potential of a numerical cost reduction. The proposed algorithm is based on the general goal-oriented error estimation theorem including both linear and nonlinear stationary partial differential equations and goal functionals. Our developments are substantiated with some numerical experiments that include comparisons of neural network computed adjoints and classical finite element solutions of the adjoints. In the programming software, the open-source library deal.II is successfully coupled with LibTorch, the PyTorch C++ application programming interface.

description: Replant disease is a worldwide phenomenon affecting various woody plant genera and species, especially within the Rosaceae. Compared to decades of intensive studies regarding replant disease of apple (ARD), the replant disease of roses (RRD) has hardly been investigated. The etiology of RRD is also still unclear and a remedy desperately needed. In greenhouse pot trials with seedlings of the RRD-sensitive rootstock Rosa corymbifera ‘Laxa’ cultured in replant disease affected soils from two different locations, early RRD symptom development was studied in fine roots. In microscopic analyses we found similarities to ARD symptoms with regards to structural damages, impairment in the root hair status, and necroses and blackening in the cortex tissue. Examinations of both whole mounts and thin sections of fine root segments revealed frequent conspicuous fungal infections in association with the cellular disorders. Particularly striking were fungal intracellular structures with pathogenic characteristics that are described for the first time. Isolated fungi from these tissue areas were identified by means of ITS primers, and many of them were members of the Nectriaceae. In a next step, 35 of these isolates were subjected to a multi-locus sequence analysis and the results revealed that several genera and species were involved in the development of RRD within a single rose plant. Inoculations with selected single isolates (Rugonectria rugulosa and Ilyonectria robusta) in a Perlite assay confirmed their pathogenic relationship to early necrotic host plant reactions, and symptoms were similar to those exhibited in ARD.

description: We report field-induced switchable polarization (P = 0.2 ~ 0.8 microC/cm2) below the Néel temperature of chromium (TN Cr) in weakly ferromagnetic rareearth orthochromites, RCrO3 (R=rareearth) but only when the rareearth ion is magnetic. Intriguingly, the polarization in ErCrO3 (TC ~ 133 K) disappears at a spin reorientation (Morin) transition (TSR ~ 22 K) below which the weak ferromagnetism associated with the Cr sublattice also disappears, demonstrating the crucial role of weak ferromagnetism in inducing the polar order. Further, the polarization (P) is strongly influenced by applied magnetic field, indicating a strong magneto electric effect. We suggest that the polar order occurs in RCrO3, due to the combined effect of poling field that breaks the symmetry and the exchange field on R ion from Cr sublattice stabilizes the polar state. We propose that a similar mechanism could work in the isostructural rareearth orthoferrites, RFeO3 as well.

description: Ein Leopardenfund aus der Baumannshöhle bei Rübeland im Harz, der mit Hilfe seiner Begleitfauna und der an der gleichen Lokalität gefundenen Artefakte in die frühe Weichsel-Eiszeit datiert werden kann, wird mit anderen in der Literatur beschriebenen pleistozänen Vorkommen von Panthera pardus (L.) und mit dem rezenten Leoparden verglichen. Es zeigt sich, daß die pleistozänen Leoparden im Durchschnitt etwas kräftiger als ihre rezenten Verwandten waren. Leichte Abweichungen von den rezenten Verhältnissen finden sich übereinstimmend bei den mittel- bis jungpleistozänen Exemplaren in der Längengliederung von P— und P— (Abb. l). Gerichtete phylogenetische Veränderungen von älteren zu jüngeren Formen lassen sich jedoch nicht nachweisen. Einige der Unterschiede, die den altpleistozänen Leoparden aus den Mauerer Sanden von den jüngeren aus dem Eem- Interglazial und der Saale-Eiszeit bzw. der späten Elster-Eiszeit trennen, werden durch den Rübeländer Fund überbrückt (Abb. 2), ohne daß deswegen an der von SOERGEL (1914) und E.SCHMID (1940) betonten und durch einen Neufund (Beschreibung S.105) bestätigten Sonderstellung des Mauerer Tieres gezweifelt werden kann. Es ist dies lediglich als Beweis dafür anzusehen, daß die Variabilität innerhalb des mittel- bis jungpleistozänen Formenkreises ebenso groß wie bei den rezenten Leoparden gewesen sein muß.

description: Photovoltaic modules for façade integration should have a widely modifiable appearance to adjust to the architect’s requirements. However, architects today usually have only a limited number of already manufactured samples to choose from. Changing the color will also change the photovoltaic yield. Therefore, it would be helpful to have a procedure that allows us to determine the appearance and expected yield in advance of module fabrication. We present such a method for creating a digital prototype of a colored building integrated photovoltaic module. Using reflectance and external quantum efficiency measurements of eight colored modules, we simulate the appearance and respective energy yield for arbitrary module colors. We validate our predictions for 29 different colored modules. We use textiles that have been colored by printing and laminate them onto the modules to change the appearance of the modules. However, our digital prototyping model is also applicable to other coloring techniques. We achieve an average color difference of ΔE00 = 1.34 between predicted and measured colors, which is barely perceptible to the human eye. The predicted short-circuit current density of the digital prototype deviates on average less than 1% from the measured one

description: We treat the ground state, elementary excitations, and neutron scattering cross section for a system of trimers consisting of three tightly bound spins 1/2 on a distorted Kagomé lattice, subject to isotropic nearest neighbor (usually antiferromagnetic) Heisenberg interactions. The interactions between trimers are assumed to be weak compared to the intra trimer interactions. We compare the spin-wave excitation spectrum of trimers with that obtained from standard spin-wave theory and attribute the differences at low energy to the fact that the trimer formulation includes exactly the effects of intra-trimer zero point motion. Application to existing systems is briefly discussed.

description: Complex Langevin dynamics can solve the sign problem appearing in numerical simulations of theories with a complex action. In order to justify the procedure, it is important to understand the properties of the real and positive distribution, which is effectively sampled during the stochastic process. In the context of a simple model, we study this distribution by solving the Fokker-Planck equation as well as by brute force and relate the results to the recently derived criteria for correctness. We demonstrate analytically that it is possible that the distribution has support in a strip in the complexified configuration space only, in which case correct results are expected.

description: Proton exchange membrane water electrolysis (PEMWE) is a key technology for future sustainable energy systems. Proton exchange membrane (PEM) electrolysis cells use iridium, one of the scarcest elements on earth, as catalyst for the oxygen evolution reaction. In the present study, the expected iridium demand and potential bottlenecks in the realization of PEMWE for hydrogen production in the targeted GW a−1 scale are assessed in a model built on three pillars: (i) an in-depth analysis of iridium reserves and mine production, (ii) technical prospects for the optimization of PEM water electrolyzers, and (iii) PEMWE installation rates for a market ramp-up and maturation model covering 50 years. As a main result, two necessary preconditions have been identified to meet the immense future iridium demand: first, the dramatic reduction of iridium catalyst loading in PEM electrolysis cells and second, the development of a recycling infrastructure for iridium catalysts with technical end-of-life recycling rates of at least 90%. © 2021 The Author(s)

description: We report studies of the magnetospectroscopy of graphite into a new regime of high energies and ultra-high magnetic fields which allows us to perform the first spectroscopic studies of the interlayer split off bands, $E_{1}$ and $E_{2}$. These bands can be well described by an asymmetric bilayer model and have only a small interlayer band gap asymmetry. We show that all of the properties of the electrons and holes can be described by a simple relativistic behaviour determined by $γ_{0}$ and $γ_{1}$.

description: This study draws on machine learning as a means to causal inference for econometric investigation. We utilize the concept of transfer entropy to examine the relationship between the US National Association of Home Builders Index and the S&P CoreLogic Case-Shiller 20 City Composite Home Price Index (SPCS20). The empirical evidence implies that the survey data can help to predict US house prices. This finding extends the results of Granger causality tests performed by Rodriguez Gonzalez et al. in 2018 using a new machine learning approach that methodologically differs from traditional methods in empirical financial research. © 2021 The Authors.

description: In part I we introduced the class ${\mathcal E}_2$ of Lie subgroups of $Sp(2,\R)$ and obtained a classification up to conjugation (Theorem 1.1). Here, we determine for which of these groups the restriction of the metaplectic representation gives rise to a reproducing formula. In all the positive cases we characterize the admissible vectors with a generalized Calderón equation. They include products of 1D-wavelets, directional wavelets, shearlets, and many new examples.

description: Two proteins with apparent molecular masses of 17 and 24 kD that are synthesized in a circadian manner in the phytoflagellate Euglena gracilis, were recognized as proteins belong­ing to the family of light-harvesting-chlorophyll-proteins (LHCPs) of class I (17 kD) and of class II (24 kD). Identification was achieved by N-terminal sequencing of the proteins isolated from two-dimensional polyacrylamide gels and by detection with an anti-LHCP II se­rum. While it was found that the total amount of LHCPs remains almost constant, when Euglena is grown under diurnal conditions (12 h light and 12 h dark), we could show that the amount of newly synthesized 17 and 24 kD proteins varies about 20-fold with a maximum of synthesis in the light phase. In contrast, the analysis of the mRNA levels at different times revealed only minor differences in the stationary concentration of the LHCP specific mRNA, indicating that the control of LHCP synthesis is at the translational level. Principally, the same finding was obtained using inhibitors of transcription. Thus, it is concluded that the expression of LHCPs in Euglena gracilis in contrast to that of higher plants is primarily regulated at the translational level.
Evolution of Genetic Redundancy : The Relevance of Complexity in Genotype-Phenotype Mapping

description: Genetic redundancy is ubiquitous and can be found in any organism. However, it has been argued that genetic redundancy reduces total population fitness, and therefore, redundancy is unlikely to evolve. In this letter, we study an evolutionary model with high-dimensional genotype-phenotype mapping (GPM) to investigate the relevance of complexity in GPM to the evolution of genetic redundancy. By applying the replica method to deal with quenched randomness, the redundancy dependence of the fitness is analytically obtained, which demonstrates that genetic redundancy can indeed evolve, provided that the GPM is complex. Our result provides a novel insight into how genetic redundancy evolves.

description: Es wurde gezeigt dass die Voraussage der vorhandenen Dämpfungseigenschaften gegen elektromagnetische Effekte generell in einem modernen Verkehrsflugzeug darauf beruht die Konstruktionsdirektiven stetig weiterzuentwickeln, um permanent alle Erfahrungen aus dem täglichen Betrieb, in aktuelle und künftige Entwicklungsprogramme einfließen zu lassen. Es ist offensichtlich, dass Versuche am komplett ausgerüsteten Flugzeug nicht mit wirtschaftlich vertretbarem Aufwand durchführbar sind. Deshalb werden in der Regel Teilsysteme oder Teilbereiche getestet. Als ein solcher Teilbereich ist eine Flugzeugtüre ein Gebilde innerhalb dessen es weitere physikalische Grenzen in der Umsetzung der Standardschutzlösungen gegen elektromagnetische Einflüsse gibt. Auf dem Weg zur zertifizierten Serienlösung ist es essentiell dass bekannte technische Lösungen angepasst oder ersetzt werden. Diese modifizierten Bauweisen müssen, in enger und permanenter Zusammenarbeit mit den Systemarchitekten und EMV-Spezialisten des Flugzeugherstellers Airbus, bewertet werden. Im Rahmen der Entwicklung und Zulassung der A350 Passagiertüren wurden detaillierte Betrachtungen, Anpassungen und Versuche angestellt und dokumentiert, die für alle weiteren Entwicklungsprogramme eine wertvolle und belastbare Basis darstellen.

description: Recent proposals for space-borne gravitational wave detectors based on atom interferometry rely on extremely narrow single-photon transition lines as featured by alkaline-earth metals or atomic species with similar electronic configuration. Despite their similarity, these species differ in key parameters such as abundance of isotopes, atomic flux, density and temperature regimes, achievable expansion rates, density limitations set by interactions, as well as technological and operational requirements. In this study, we compare viable candidates for gravitational wave detection with atom interferometry, contrast the most promising atomic species, identify the relevant technological milestones and investigate potential source concepts towards a future gravitational wave detector in space.

description: Die Röntgenstrukturanalysen der hier aufgelisteten Verbindungen gehen zurück auf die Zeit vor 2005, die zugehörigen CIFs wurden jedoch erst 2016 und 2017 beim FIZ Karlsruhe oder CCDC (Cambridge) deponiert. Im Arbeitskreis Binnewies wurden sehr viele Verbindungen mittels der Methode des Chemischen Transports synthetisiert. Literatur hierzu z. B.: Patzke, G. R.: Darstellung, Charakterisierung und Eigenschaften oxidischer Mischphasen, Thesis, Univ. Hannover (1999); Pfeifer, A.: Chemischer Transport von Germanaten, Thesis, Univ. Hannover (2001); Locmelis, S.: Chemischer Transport oxidischer Mischphasen mit ZnO, Ga2O3 und TiO2 als Wirtsgitter, Thesis, Univ. Hannover (1999); Patzke, G. R. & Binnewies, M.: Feste Lösungen, Chemie in unserer Zeit 33 (1999) 33-34; weitere Literaturangaben in den CIFs. Standardmäßig wurden die Verbindungen mit dem Röntgenpulverdiffraktometer untersucht, nur einige kamen bei geeigneter Kristallgröße zur Einkristallstrukturanalyse. Die ersten 19 Strukturen stammen aus diesem Bereich. Es folgen zwei Nebenprodukte und als Abschluss des anorganischen Teils 4 Granate aus Sandproben. Den Tipp, im Sand des Nordseestrandes nach Granat zu suchen, gab O. Medenbach, Bochum. Die Mikrosondenanalyse führte J. Koepke vom Mineralogischen Institut durch. Den zweiten Teil der Nachträge bilden organische Strukturen, hauptsächlich aus dem Arbeitskreis von H. Duddeck.

description: The analysis of entangled atomic ensembles and their application for interferometry beyond the standard quantum limit requires an accurate determination of the number of atoms. We present an accurate fluorescence detection technique for atoms that is fully integrated into an experimental apparatus for the production of many-particle entangled quantum states. Number-resolved fluorescence measurements with single-atom accuracy for 1 up to 30 atoms are presented. According to our noise analysis, we extrapolate that the single-atom accuracy extends to a limiting atom number of 390(20) atoms. We utilize the accurate atom number detection for a number stabilization of the laser-cooled atomic ensemble. For a target ensemble size of 7 atoms prepared on demand, we achieve a 92(2)% preparation fidelity and reach number fluctuations 18(1) dB below the shot noise level using real-time feedback on the magneto-optical trap.

description: Wave scattering from rough surfaces in addition the inverse scattering is an interesting approach to obtain the surface topography properties in various fields. Analytical expression in wave scattering from some known rough surfaces, not only help us to understand the scattering phenomena, but also would prove adequate to be a criterion to measure the information for empirical rough surfaces. For a rough surface with an exponential height correlation function, we derive an analytical expression for the diffused part and expanded it in two asymptotic regimes. We consider one surface as slightly rough and the other as very rough based on the framework of the Kirchhoff theory. In the end, we have measured the role of various Hurst exponents and correlation lengths on scattering intensity in self-affine surfaces. We have shown that by increasing the Hurst exponent from H=0 to H=1, the diffuse scattering decreases with the scattering angle.
