description: Seasonal floodplains under private and public ownership in the Indo-Ganges river basin provide food and income for millions of people in Bangladesh. Floodplain ownership regimes are diverse, covering the whole spectrum from public to private ownership. The paper compares community-based fish culture projects in these floodplains and analyzes the institutional arrangements of three different Floodplain Management Committees (FMC). The paper aimed to understand the complex institutional relations that govern ownership, access, and control of the floodplains under community-based fish culture (CBFC) to increase fish production and the livelihoods of the poor. We followed the stakeholders representing the various institutions and organizations such as the Department of Fisheries (DoF), Department of Land (DoL), and FMC. Other important stakeholders were the lease-holders of public water bodies in the floodplains, private landowners, seasonal, and professional fishers. The analysis demonstrates a significant increase of benefits to all stakeholders, including the poor, through the sharing of benefits derived from their involvement in the project. The willingness of different social classes to work together, the adoption of new technologies, and the societal embeddedness of local government institutions appear to be important inputs for policy making.
Quantum Ultra-Walks: Walks on a Line with Hierarchical Spatial Heterogeneity

description: We discuss the model of a one-dimensional, discrete-time walk on a line with spatial heterogeneity in the form of a variable set of ultrametric barriers. Inspired by the homogeneous quantum walk on a line, we develop a formalism by which the classical ultrametric random walk as well as the quantum walk can be treated in parallel by using a "coined" walk with internal degrees of freedom. For the random walk, this amounts to a $2^{\rm nd}$-order Markov process with a \emph{stochastic} coin, better known as an (anti-)persistent walk. When this coin varies spatially in the hierarchical manner of "ultradiffusion," it reproduces the well-known results of that model. The exact analysis employed for obtaining the walk dimension $d_{w}$, based on the real-space renormalization group (RG), proceeds virtually identical for the corresponding quantum walk with a $unitary$ coin. However, while the classical walk remains robustly diffusive ($d_{w}=\frac{1}{2}$) for a wide range of barrier heights, unitarity provides for a quantum walk dimension $d_{w}$ that varies continuously, for even the smallest amount of heterogeneity, from ballistic spreading ($d_{w}=1$) in the homogeneous limit to confinement ($d_{w}=\infty$) for diverging barriers. Yet for any $d_{w}

description: This thesis examines the relationship between language and Roman identity, defined in the broadest sense as the political and cultural practices involved in being Roman. It focuses on evidence of multilingualism: Roman identity was defined through opposition and interaction, and it is at points of contact that these debates are cast into relief. It looks predominantly at evidence of Greek-Latin bilingualism, but also considers evidence of other languages to consider how their relationship to Roman identity differs. It combines historical and sociolinguistic approaches to multilingualism. Understanding bilingual language practices requires close sociolinguistic reading of evidence to understand how languages interrelate and analysis of the historical factors and contexts that determine language choices and their social, cultural and political implications. The thesis responds especially to the use of bilingualism as a model for Roman cultural relations, arguing that a closer engagement with sociolinguistic terminology and with linguistic evidence is necessary if we are to use language and bilingualism as a way into broader issues of politics and identity. Language is simultaneously a model for identity that works across ancient and modern thought and a central part of this identity. It frequently plays into other markers of Roman identity and a range of themes and concerns surrounding it including integration, migration and citizenship. The thesis examines three case studies in detail: the different layers of bilingualism in Suetonius’ biographies; Greek in the graffiti of Pompeii; epigraphic and literary evidence for different languages in the city of Rome. These case studies demonstrate the politics of language in different types of practice and at different levels of society: the thesis argues that the overlaps between them are greater than has sometimes been appreciated. The case studies also show that the boundaries of Roman identity did not develop in a progressive or linear fashion but were continually defined and redefined through ongoing processes of absorption and rejection.

description: The Stanford Synchrotron Radiation Laboratory is investigating an accelerator upgrade project that would replace the present 130 nm rad FODO lattice with an 18 nm rad double bend achromat (DBA) lattice: SPEAR 3. The low emittance design yields a high brightness beam, but the stronger focusing in the DBA lattice increases chromaticity and beam sensitivity to machine errors. To ensure efficient injection and long Touschek lifetime, an optimization of the design lattice and dynamic aperture has been performed. In this paper, we review the methods used to maximize the SPEAR 3 dynamic aperture including necessary optics modifications, choice of tune and phase advance, optimization of sextupole and coupling correction, and modeling effects of machine errors, wigglers and lattice periodicity.

description: The RS CVn-type binary $σ$ Geminorum was observed during a large, long-duration flare simultaneously with {\it XMM-Newton} and the VLA. The light curves show a characteristic time dependence that is compatible with the Neupert effect observed in solar flares: The time derivative of the X-ray light curve resembles the radio light curve. This observation can be interpreted in terms of a standard flare scenario in which accelerated coronal electrons reach the chromosphere where they heat the cool plasma and induce chromospheric evaporation. Such a scenario can only hold if the amount of energy in the fast electrons is sufficient to explain the X-ray radiative losses. We present a plausibility analysis that supports the chromospheric evaporation model.

description: Hypercomplex-valued neural networks, including quaternion-valued neural networks, can treat multi-dimensional data as a single entity. In this paper, we introduce the quaternion-valued recurrent projection neural networks (QRPNNs). Briefly, QRPNNs are obtained by combining the non-local projection learning with the quaternion-valued recurrent correlation neural network (QRCNNs). We show that QRPNNs overcome the cross-talk problem of QRCNNs. Thus, they are appropriate to implement associative memories. Furthermore, computational experiments reveal that QRPNNs exhibit greater storage capacity and noise tolerance than their corresponding QRCNNs.

description: In this work, we investigate quantum Fisher information(QFI) and quantum coherence(QC) of an atom in dissipative cavity. In zero temperature reservior and with one excitation number, we obtain the analytical solutions of QFI and QC as well as their relationship for Ohmic and Lorentzian reservoir, respectively. The results show that both of the atom-cavity coupling and the cavity-reservoir coupling can effectively protect QFI and QC. Especially, QFI and QC will tend to their stable values when the atom-cavity coupling or the cavity-reservoir coupling is larger than a certain value. QC can augment QFI and can effectively improve the quantum metrology. In addition, we give a physical explanation of the dynamic behavior of QFI and QC by using the decoherence rate.

description: This study challenges the positivist view of the Korean Constitution, which sees it merely as an assemblage of rules and statutes defining its citizens’ status and setting out codes of conduct for the government, or mapping the government’s institutional arrangements. Prevalent in Korean constitutional thought and practice, this view wholly fails to capture what it implies for how the polity governs or is governed. Because it assumes that the state and its constitutional law came into being prior to any structure of political entitlement, Korean constitutional scholarship has focused only its textual meaning and assessing the relative weight of individual statutes or articles of the Constitution. This has narrowed scholarly inquiry into the political significance of the Constitution into a dispute over the source of sovereignty. The dissertation aims to (re)discover the political nature of the Korean constitution with the 1962 and 1972 constitutions.

description: Methodology:
On March 5, 2021, a five-hour virtual workshop was held with representatives of possible data exchange institutions for DBIS. The goal was to uncover needs and opportunities, as well as to identify starting points for future data exchange. The following section begins by describing the goals, structure, and participants of the activity.

Aim of the measure:
The goal was, as described in the DFG application, to find ways to better integrate DBIS into the library information infrastructure. For this purpose, relevant partners were invited to present usage scenarios, which led to an open discussion. The focus was on how databases should be treated as e-resources in the library context, how data flows can be established and what purposes they can serve.

Concept:
Representatives from different institutions were invited to present different usage scenarios. Each group prepared a presentation for which a template was distributed in advance and which was then openly discussed. At the end of the workshop, another open discussion was planned on further open points from the group presentations, as well as overarching topics. In the context of the COVID-19 pandemic, the workshop could only take place as a virtual event. The teleconference system "Zoom" was used for this purpose.

Participants:
The DBIS team invited suitable representatives who presented the following systems and their possibilities and needs:
"GOKb" (Global Open Knowledgebase).
"ZDB" (German Union Catalogue of Serials)
"LAS:eR" (Electronic Resource Management System (ERM))
"FOLIO" (library system "The Future Of Libraries Is Open")
"FIDELIO" (verification tool for FID licenses)

Procedure: 
After a welcome by Dr. Schüller-Zwierlein, the director of the University Library Regensburg, the participants briefly introduced themselves. The core event was divided into 3 blocks. Each group was allotted 30 minutes, 15 minutes for the presentation and 15 minutes for the subsequent discussion. In block I GOKb and ZDB presented their scenarios, in block II LAS:eR and FOLIO, block III was for FIDELIO and the open discussion. Finally, the results were summarized and an outlook on further collaboration was given and the participants were bid farewell.

Evaluation:
During the event, detailed minutes were taken. This was condensed and the statements were taken into account by the team in the requirements specification.

description: The prolonged drought of recent years combined with the steadily increasing bark beetle infestation (Ips typographus) is causing enormous damage in Germany’s spruce forests. This preliminary study investigates whether early spruce infestation by the bark beetle (green attack) can be detected using indices based on airborne spatial high-resolution (0.3 m) hyperspectral data and field spectrometer measurements. In particular, a new hyperspectral index based on airborne data has been defined and compared with other common indices for bark beetle detection. It shows a very high overall accuracy (OAA = 98.84%) when validated with field data. Field measurements and a long-term validation in a second study area serve the validation of the robustness and transferability of the index to other areas. In comparison with commonly used indices, the defined index has the ability to detect a larger proportion of infested spruces in the green attack phase (60% against 20% for commonly used indices). This index confirms the high potential of the red-edge domain to distinguish infested spruces at an early stage. Overall, our index has great potential for forest preservation strategies aimed at the detection of infested spruces in order to mitigate the outbreaks.

description: Aminophosphates are the focus of research on prebiotic phosphorylation chemistry. Their bifunctional nature also makes them a powerful class of organocatalysts. However, the structural chemistry and dynamics of proton-binding in phosphorylation and organocatalytic mechanisms are still not fully understood. Aminophosphine chalcogenides, preserving the H2N–P+–Ch− structural motif, represent well-suited molecular models that mimic proton-binding, hydrogen-bond switching and supramolecular self-assembling behavior of catalytically and prebiotically relevant molecules. Through spectroscopic (IR, 1H DOSY, 15N NMR), molecular dynamics, and computational investigations, the dynamic proton switching capability of aminophosphate analogs was demonstrated. It was shown under which conditions the amino (NH2) or chalcogen (Ch) functions in H2N–P+–Ch− structural units are protonated. In fact, all conceivable modes of hydrogen-bonding were identified, revealing substantial differences between the oxygen derivative and the heavier congeners. Using coordinating anions, supramolecular zigzag- and cube-shaped arrangements were found in the solid-state and in solution. After break-up of the cube structure, the sulfides and selenides no longer form stable interactions with HCl molecules. In the absence of coordinating anions, protonation of the chalcogen function is preferred. In contrast to the oxygen derivative, the heavier congeners show dynamic intramolecular proton-hopping between the chalcogen and the amino function.

description: When phonons couple to fermions in 2D semimetals, the interaction may turn the system into an insulator. There are several insulating phases in which the time reversal and the sublattice symmetries are spontaneously broken. Examples are many-body states commensurate to Haldane's staggered flux model or to lattice models with periodically modulated strain. We find that the effective field theories of these phases exhibit characteristic Chern-Simons terms, whose coefficients are related to the topological invariants of the microscopic model. This implies that the corresponding quantized Hall conductivities characterize these insulating states.

description: Characterizing the elastic properties of soft materials through bulge testing relies on accurate measurement of deformation, which is experimentally challenging. To avoid measuring deformation, we propose a hydrodynamic bulge test for characterizing the material properties of thick, pre-stressed elastic sheets via their fluid--structure interaction with a steady viscous fluid flow. Specifically, the hydrodynamic bulge test relies on a pressure drop measurement across a rectangular microchannel with a deformable top wall. We develop a mathematical model using first-order shear-deformation theory of plates with stretching, and the lubrication approximation for Newtonian fluid flow. Specifically, a relationship is derived between the imposed flow rate and the total pressure drop. Then, this relationship is inverted numerically to yield estimates of the Young's modulus (given the Poisson ratio), if the pressure drop is measured (given the steady flow rate). Direct numerical simulations of two-way-coupled fluid--structure interaction are carried out in ANSYS to determine the cross-sectional membrane deformation and the hydrodynamic pressure distribution. Taking the simulations as ``ground truth,'' a hydrodynamic bulge test is performed using the simulation data to ascertain the accuracy and validity of the proposed methodology for estimating material properties. An error propagation analysis is performed via Monte Carlo simulation to characterize the susceptibility of the hydrodynamic bulge test estimates to noise. We find that, while a hydrodynamic bulge test is less accurate in characterizing material properties, it is less susceptible to noise, in the input (measured) variable, than a hydrostatic bulge test.

It is shown that the Ward identity requires the inclusion of a new diagram in the integral equation for the vertex that has not been considered before. The real part of this diagram is subleading and therefore the final expressions for the electrical conductivity at leading logarithmic order are not affected.

description: This thesis explores the existence and outlook of a European officer class in the mid- to later 18th century by studying the army officers of Britain and the Habsburg Monarchy from the War of the Austrian Succession to the eve of the French Revolutionary Wars. It illuminates the character of such an officer class of ‘Military Europe’ with its own cultural customs and practices. Furthermore, it details similarities, differences and peculiarities of both officer corps. This is achieved by analysing the social and national composition of both armies, with a focus here on the Habsburg Army due to the fact that it took in great numbers of foreigners and that the muster lists give an indication of how great the proportion of nobility was. A comparison with the British case shows striking similarities but also obvious differences. In a further step the ability of individuals for social advancement and national mobility is scrutinised on both sides. In this context, the state’s care for its officers and their social security is also taken into account. One possibility to acknowledge the officers’ service was to raise their status, either by ennoblement or through increasing the prestige of the uniform in court and society, its transformation into an ‘Ehrenkleid’ (garment of honour). As officers increasingly became servants to the state, rather than noble retainers and military enterprisers, they were also subject to professionalization efforts by the sovereigns. What becomes apparent, however, is that the officers did not only react to such measures but that at least a significant part of them actively worked on improving the service, thereby exhibiting a growing professionalism. In order to explore the coherence of the officer corps in those armies, with officers all following the same codes and accepting each other as equals, the thesis looks into core values (including honour, duty, courage and loyalty) binding them together and separating them from the enlisted men. The thesis will also offer a glimpse of their engagement with civilian society and culture as well as their role as ‘foot soldiers of Enlightenment’. On a European level, interaction between these officers proves their general acceptance of and respect for each other, while at the same time acting as state representatives in wartimes. Their interaction with non-European and non-state military forces and their leadership marks out the fluid boundaries of military Europe, but also exhibits the pervasiveness of European military culture.

description: During macroautophagy/autophagy, the ULK complex nucleates autophagic precursors, which give rise to autophagosomes. We analyzed, by live imaging and mathematical modeling, the translocation of ATG13 (part of the ULK complex) to the autophagic puncta in starvation-induced autophagy and ivermectin-induced mitophagy. In nonselective autophagy, the intensity and duration of ATG13 translocation approximated a normal distribution, whereas wortmannin reduced this effect and shifted to a log-normal distribution. During mitophagy, multiple translocations of ATG13 with increasing time between peaks were observed. We hypothesized that these multiple translocations arise because the engulfment of mitochondrial fragments required successive nucleation of phagophores on the same target, and a mathematical model based on this idea reproduced the oscillatory behavior. Significantly, model and experimental data were also in agreement that the number of ATG13 translocations is directly proportional to the diameter of the targeted mitochondrial fragments. Thus, our data provide novel insights into the early dynamics of selective and nonselective autophagy.

Productivity Analysis

description: Some studies have reported a slowdown in U.S. farm productivity growth, but the prevalent view among economists is to reject or downplay the slowdown hypothesis, implying that the rates of productivity growth experienced over the past half century can be projected forward. We set out to resolve this issue, which matters both for understanding the past and anticipating the future. Using newly compiled multifactor and partial-factor productivity estimates, developed for the purpose, we examine changes in the pattern of U.S. agricultural productivity growth over the past century. We detect sizable and significant slowdowns in the rate of productivity growth. Across the 48 contiguous states for which we have very detailed data for 1949–2007, U.S. multifactor productivity (MFP) growth averaged just 1.18 percent per year during 1990–2007 compared with 2.02 percent per year for the period 1949–1990. MFP in 44 of the 48 states has been growing at a statistically slower rate since 1990. Using a longer-run national series, since 1990 productivity growth has slowed compared with its longer-run growth rate, which averaged 1.52 percent per year for the entire period, 1910–2007. More subtly, the historically rapid rates of MFP growth during the 1960s, 1970s and 1980s can be seen as an aberration relative to the long-run trend. A cubic time-trend model fits the data very well, with an inflection around 1962. We speculate that a wave of technological progress through the middle of the twentieth century—reflecting the progressive adoption of various mechanical innovations, improved crop varieties, synthetic fertilizers and other chemicals, each in a decades long process—contributed to a sustained surge of faster-than-normal productivity growth throughout the third quarter of the century. A particular feature of this process was to move people off farms, a one-time transformation of agriculture that was largely completed by 1980.

description: At the Accelerator Test Facility (ATF) at KEK intrabeam scattering (IBS) is a strong effect for an electron machine. It is an effect that couples all dimensions of the beam, and in April 2000, over a short period of time, all dimensions were measured as functions of current. In this report we derive a simple relation for the growth rates of emittances due to IBS. We apply the theories of Bjorken-Mtingwa, Piwinski, and a formula due to Raubenheimer to the ATF parameters, and find that the results all agree (if in Piwinski's formalism we replace the dispersion squared over beta by the dispersion invariant). Finally, we compare theory, including the effect of potential well bunch lengthening, with the April 2000 measurements, and find reasonably good agreement in the energy spread and horizontal emittance dependence on current. The vertical emittance measurement, however, implies that either: there is error in the measurement (equivalent to an introduction of 0.6% x-y coupling error), or the effect of intrabeam scattering is stronger than predicted (35% stronger in growth rates).

description: Excerpt from the report Summary: This is the first report in a series of relationship studies on cotton fiber properties which deals with single-strand yarn strength. All previous studies of this series dealing with yarn-strength have involved the measure of skein strength. The two tests of yarn strength, however, differ radically in a number of particulars. Predicting equations and related information are helpful to the cotton trade and textile industry in choosing cottons best suited to the manufacture of specific products, in selecting blends of cotton for processing, and for meeting different levels of product quality. Such equations and knowledge also give assistance to cotton breeders by informing them of the fiber properties which are important to their programs. This publication gives 13 equations, based on various measures of raw-cotton quality, for predicting single-strand strength and elongation of any size of carded yarn within a relatively wide range. Ten of the equations refer to yarn strength and three to yarn elongation. The precision of estimate expected with each equation is shown.

description: Le but de ce mémoire était, d’une part, de voir le lien possible entre la pratique du jeu vidéo Minecraft et quelques concepts de la physique quantique, et d’autre part, d’évaluer l’impact d’une séquence avec Minecraft, et en particulier avec le mod qCraft (quantum Craft), sur l’apprentissage de ces concepts de physique quantique chez des élèves de secondaire, ainsi que sur leur motivation. Mais pourquoi la physique quantique ? Parce que nous allons entrer dans un monde où la nature se comporte d’une façon probablement étrange, mais qui est bien réelle. Il y a du hasard, un hasard auquel on ne peut pas échapper, il y a des êtres qui changent tout à coup d’état, ou qui perdent soudainement leur mémoire, mais qui peuvent aussi être en contact avec une autre être qui est à des années-lumière de distance…et ne jamais l’oublier, en maintenant un lien permanent. Un monde qui sait aussi garder ses secrets, car personne, aussi puissant et intelligent soit-il, ne va pouvoir intercepter leurs messages. Ceci est le monde quantique, un monde complexe mais tellement passionnant, curieux et riche…et pourtant si peu enseigné à l’école. Et pourquoi un jeu vidéo ? Parce qu’aujourd’hui le jeu vidéo est un des media numériques qui attire une grande partie des adolescentes, et alors, pourquoi pas rapprocher l’éducation des jeux vidéo et ainsi pouvoir profiter de la composante ludique de ceux-ci pour atteindre quelques objectifs d’apprentissage ? Pour cette raison, nous souhaitions, en parallèle, mettre à disposition de l’enseignant une série d’outils didactiques pour pouvoir justement implémenter un scénario pédagogique, concernant le monde quantique, autour de Minecraft. À savoir, les différents concepts de physique quantique et leur transposition didactique dans Minecraft, et particulièrement, le protocole BB84 de cryptographie quantique.
The mesenchymal regulation of ductal-driven liver regeneration

description: Liver epithelial cells –hepatocytes and bile duct cells– intermingle with a microenvironment of endothelial cells, macrophages and mesenchymal cells to form the functional unit of the tissue. In chronic or severe liver injury, when hepatocyte proliferation is compromised, ductal cells become activated into bipotential progenitors to replace lost epithelium. This process can be recapitulated in vitro by growing hepatic ductal cells under defined extracellular matrix and growth factors, which generates 3D epithelial 'liver organoids' that resemble adult tissue, yet lack stromal cell components (Huch et al., 2013). In this dissertation, we compared the capacity of two broad hepatic stromal cell populations, hematopoietic/endothelial (H/E) and mesenchymal (Msc) cells, to behave as a nurturing ‘niche’ of the ductal epithelium. In the absence of exogenous growth factors, primary Msc but not H/E cells support ductal cell proliferation and organoid formation in vitro. A cell surface marker screen of the Msc fraction showed labelling of up to 20% of the cells by the stem cell antigen 1 (SCA1). In vivo, SCA1+PDGFRα+ mesenchymal cells localise periportally, closely surrounding biliary duct cells, and co-expanding with them during damage- induced regeneration. Isolated SCA1+ mesenchymal cells express key pro- regenerative factors (Hgf, Rspo1/3, Fgf7), and support liver organoid formation independently of cell-to-cell contact. Mesenchyme-sustained organoids resemble those grown in standard medium, although they are biased towards a more mature ductal cell lineage. Liver organoids can in turn support the expansion of SCA1+ Msc cells in vitro, suggesting a positive feedback loop of growth. However, physical contact from the SCA1+ Msc cells can be cytostatic for the ductal cells depending on the ratio between the two cell populations. Interestingly, the mesenchymal-to-ductal ratios that permit and inhibit ductal proliferation in vitro recapitulate the ratios observed between the two populations in vivo, during the different phases of liver regeneration. Our findings underscore how the relationship between the ductal epithelium and its mesenchymal microenvironment regulates tissue regeneration, and provide avenues for the development of organotypic liver cultures to model epithelial/mesenchymal interactions in vitro.

Implications of the Narrow Period Distribution of Anomalous X-ray Pulsars and Soft Gamma-Ray Repeaters

description: The spin periods of the ten observed Anomalous X-ray Pulsars and Soft Gamma-ray Repeaters lie in the very narrow range 6-12 s. We use a point likelihood technique to assess the constraints this clustering imposes on the birth period and on the final period of such systems. We consider a general law for their spin evolution described by a constant braking index. We find that, for positive values of the braking index, the observed clustering requires an upper cut-off period that is very close to the maximum observed period of about 12 s. We also show that the constraint on the birth period depends very strongly on the assumed value of the braking index n, ranging from a few milliseconds for n>2 to a few seconds for n<2. We discuss the possible ways of tightening these constraints based on similarities with the population of radio pulsars and with future observations of such sources with current X-ray observatories.
