description: We experimentally realized a new method for transmitting quantum information reliably through paired optical polarization-maintaining (PM) fibers. The physical setup extends the use of a Mach-Zehnder interferometer, where noises are canceled through interference. This method can be viewed as an improved version of the current decohernce-free subspace (DFS) approach in fiber optics. Furthermore, the setup can be applied bidirectionally, which means that robust quantum communication can be achieved from both ends. To rigorously quantify the amount of quantum information transferred, optical fibers are analyzed with the tools developed in quantum communication theory. These results not only suggests a practical means for protecting classical and quantum information through optical fibers, but also provides a new physical platform for enriching the structure of the quantum communication theory.

description: Bulk monolithic samples of γ-Fe2O3/SiO2 composites with different iron oxide/silica ratios have been prepared by the sol-gel technique. Iron oxide nanoparticles are obtained in-situ during heat treatment of samples and silica matrix consolidation. Preparation method was previously optimized to minimize the percentage of antiferromagnetic α-Fe2O3 and parallelepipeds of roughly 2x5x12 mm3, with good mechanical stability, are obtained. RT magnetization curves show a non-hysteretic behavior. Thus, magnetization measurements have been well fitted to an expression that combines the Langevin equation with an additional linear term, indicating that some of the nanoparticles are still superparamagnetic as confirmed by X-ray diffraction and electron microscopy measurements. Zero field cooled /field cooled experiments show curves with slightly different shapes, depending on the size and shape distribution of nanoparticles for a given composition. Magneto-optical Faraday effect measurements show that the Faraday rotation is proportional to magnetization of the samples, as expected. As a demonstration of their sensing possibilities, the relative intensity of polarized light, measured at 5° from the extinction angle, was plotted versus applied magnetic field.

description: Does a government in a bicameral system strategically alter the length of the legislative process in the first chamber in anticipation of future majorities in the second chamber? Drawing on an existing formal model of dynamic policymaking, we argue that governing majorities strategically accelerate or delay their agenda when a potential majority change in the second chamber is imminent. If the government fears losing control over the second chamber, then the government accelerates their agenda. By contrast, if the government hopes to gain control over the second chamber, the government decelerates their agenda. We test our argument in Germany's symmetric and asymmetric bicameralism by analyzing 1,966 governmental bills from 1998 to 2013. The analyses confirm our expectations for symmetric bicameralism, thus suggesting that the synchronicity of election cycles should be taken into account both in the analysis of bicameral systems and in institutional design of such systems. © 2020 The Authors.

description: Η Ελλάδα βασίζεται σε μεγάλο βαθμό στην ιατρική φροντίδα των πολιτών από τα φαρμακεία. Για το 2021, συνολικά λειτουργούν 10427 φαρμακεία, εκ των οποίων, 35.2% βρίσκονται στην Αττική. Απότοκο αυτού, ο δείκτης φαρμακείων ανά 10000 κατοίκους να είναι στο 9.7 (Healthstories, 2021). Αυτό έρχεται σε σύγκριση με το μέσο όρο των παγκοσμίων δεικτών φαρμακείων ανά 10000 κατοίκους, ο οποίος ήταν 2.78 την ίδια χρονική περίοδο (FIP,2021). Συνεπακόλουθα, οι ασθενείς έχουν ευκολότερη πρόσβαση σε φαρμακεία, παράλληλα όμως, υπάρχει εντονότερος ανταγωνισμός μεταξύ των επιχειρήσεων. Στα φαρμακεία έχει γίνει αισθητή η αύξηση του ανταγωνισμού, αφού ο ρυθμός ανάπτυξης των online φαρμακείων στο πρώτο τετράμηνο του 2021 ήταν στο 38.3% (Danielienė, I. 2021). Αυτή η αύξηση σε ένα κλάδο περιορισμένο που δεν μπορεί να επιβιώσει σε red ocean, δημιούργησε μεγάλες μεταβολές και αστάθεια στο επάγγελμα τόσο στα online όσο και στα φυσικά καταστήματα αφού οι πελάτες, πλέον, έχουν μάθει να αγοράζουν διαδικτυακά εκμεταλλευόμενοι τις καλύτερες εκπτώσεις. Επίσης, η απαγόρευση του marketing για τα φυσικά φαρμακεία, αλλά η χρήση του στα online, δίνει ένα πολύ σημαντικό πλεονέκτημα σε εκείνα που έχουν επενδύσει στον ψηφιακό τομέα. Εν συνεχεία, οι περιορισμοί που υπάρχουν από την κυβέρνηση, διαρκώς μειώνονται λόγω των συνεχών αλλαγών της νομοθεσίας σε όλον τον κόσμο. Η Ελλάδα είναι μια από τις πέντε τελευταίες χώρες που απαγορεύουν την πώληση μη συνταγογραφούμενων φαρμάκων online (Danielienė, I. 2021). Οι αλλαγές που ψηφίζονται στην Ευρωπαϊκή Ένωση, αυξάνουν τις απειλές της ένταξης των μη συνταγογραφούμενων φαρμάκων στα ψηφιακά καταστήματα των φαρμακείων και σε άλλα κανάλια διανομής, κάτι που πιθανότατα να συντελέσει στη μείωση του δείκτη φαρμακείων ανά 10000 κατοίκους.
Quantum Hall Effects with High Spin-Chern Numbers in Buckled Honeycomb Structure with Magnetic Order

description: As a topological insulator, the quantum Hall (QH) effect is indexed by the Chern and spin-Chern numbers $\mathcal{C}$ and $\mathcal{C}_{\text{spin}}$. We have only $\mathcal{C}_{\text{spin}}=0$ or $\pm \frac{1}{2}$ in conventional QH systems. We investigate QH effects in generic monolayer honeycomb systems. We search for spin-resolved characteristic patterns by exploring Hofstadter's butterfly diagrams in the lattice theory and fan diagrams in the low-energy Dirac theory. The Chern and spin-Chern numbers are calculated based on the bulk-edge correspondence in the lattice theory and on the Kubo formula in the Dirac theory. It is shown that the spin-Chern number can takes an arbitrary high value for certain QH systems in coexistence with buckled structure and magnetic order. This is a new type of topological insulators. Samples may be provided by silicene with ferromagnetic order and transition-metal oxide with antiferromagnetic order.

title: Life in the Fells: names in a nineteenth-century Cumberland landscape
Creators: name: Colla, Chloe
Publisher: name: University of Glasgow
Year: 2023

description: This thesis examines the field-names of Crosthwaite parish, Cumberland. A survey of the fieldnames and a corresponding glossary of elements and their localised usage(s) within the study area, some previously unattested, form a significant part of the thesis. The field-name data is compiled chiefly from nineteenth-century Tithe Awards which records the names and descriptions of Crosthwaite’s 8,626 land units, 3,351 of which are field-names (3.4.1). These 3,351 field-names, recorded in the survey (Chapter Four), contain 6,052 elements which fall into 586 element types, presented in the glossary (Chapter Five). The work of this thesis is underpinned by the data from two key resources which were created as part of this research: a) a field-name dataset composed of all linguistic data held within the Tithe Awards for the parish (3.1); and b) an interactive digital map of all 8,626 land units, into which the field-name data is embedded (3.3). The first resource – the onomastic data – allows for the fieldnames to be analysed linguistically. The second – the cartographical data – allows for the fieldnames to be analysed spatially, enabling the evidence of the landscape to inform the interpretation and analysis of the names. A quantitative analysis of all Crosthwaite’s field-name elements (Chapter Six) highlights the close relationship between the language of the field-names and the landscape they describe. The extent to which the field-names reflect their landscape is marked and is observable both in the use of individual elements, and in the language use of townships within the parish more broadly. The survey (Chapter Four) and glossary (Chapter Five) constitute a substantial contribution to the available field-name data for Cumberland, and for England more generally, supplementing the English Place-Name Society survey for Cumberland. Other key findings from this research (Chapter Seven) include the discovery of metaphorical elements unattested elsewhere, as well as other elements or element usages particular to the study area. Field-names which provide evidence for lost place-names, and instances of toponomastic overlap between England and Scotland, are observable within the data of this thesis; a lack of genitival -s in personal names within field-names is likewise notable. This thesis advocates for the development and implementation of a new field-name terminology model.

description: The method of increasing the reliability of the development of multiple organ failure is as follows: they analyze the state of central and peripheral hemodynamics using ultrasound methods. In the first 24 hours of child's life, the fraction of shortening of the left ventricle in systole and the resistance index of the main arteries of target organs are calculated: for the brain in the anterior cerebral artery, for the gastrointestinal tract in the superior cerebral artery, for the kidneys in the left and right renal arteries. The development of multiple organ failure is predicted with a simultaneous decrease in the left ventricular shortening fraction of less than 34% and an increase in resistance index in at least one organ of more than 0.8. The method allows to increase the reliability and efficiency of predicting the likelihood of developing PON in newborns in critical condition by measuring the ratio of regional blood flow indicators in the kidneys, gastrointestinal tract and brain and central hemodynamic parameters.

description: We study spectral properties of Hamiltonians $\rH_{X,\gB,q}$ with $δ'$-point interactions on a discrete set $X={x_k}_{k=1}^\infty\subset\R_+$. %at the centers $x_n$ on the positive half line in terms of energy forms. Using the form approach, we establish analogs of some classical results on operators $\rH_q=-d^2/dx^2+q$ with locally integrable potentials $q\in L^1_{\loc}(\R_+)$. In particular, we establish analogues of the Glazman-Povzner-Wienholtz theorem, the Molchanov discreteness criterion, and the Birman theorem on stability of an essential spectrum. It turns out that in contrast to the case of Hamiltonians with $δ$-interactions, spectral properties of operators $\rH_{X,\gB,q}$ are closely connected with those of $\rH_{X,q}^N=\oplus_{k}\rH_{q,k}^N$, where $\rH_{q,k}^N$ is the Neumann realization of $-d^2/dx^2+q$ in $L^2(x_{k-1},x_k)$.

description: The aim of this work is to study the influence of selected deep rolling parameters (rolling pressure and number of passes) on the surface integrity of fully annealed AISI 1060 high carbon steel. In addition to the mechanical properties, a comprehensive investigation on surface integrity is carried out. The findings indicate that despite the increase in surface hardness and ultimate tensile stress, deep rolling can negatively affect the yield strength. The amplitude and functional roughness parameters show a considerable reduction after deep rolling, however, increasing rolling pressure and number of passes leads to poorer surface finish. Finally, the tensile residual stress generated by turning shifts to compressive values after deep rolling and the microhardness and microstructure analyses indicate that the depth of the layer affected by deep rolling depends on both the rolling pressure and number of passes.

description: We realized ambipolar Field-Effect Transistors by coupling exfoliated thin flakes of tungsten disulphide (WS2) with an ionic liquid-dielectric. The devices show ideal electrical characteristics, including very steep sub-threshold slopes for both electrons and holes and extremely low OFF-state currents. Thanks to these ideal characteristics, we determine with high precision the size of the band-gap of WS2 directly from the gate-voltage dependence of the source-drain current. Our results demonstrate how a careful use of ionic liquid dielectrics offers a powerful strategy to study quantitatively the electronic properties of nano-scale materials.

description: The vertical distribution pattem of mesofaunal elements is described from clay-marl bedding rhythms from the Frielingen section (Hannover, NW Germany), which exposes latest Hau- terivian sediments (early Cretaceous). Some mesofaunal groups show a correlation with the pale- dark bedding rhythms. The pale, marly beds are chracterised by bryozoans. In addition remnants of crinoids, echinoids, asteroids, ophiuroids and holothuroids are more common in pale layers than in dark ones. Converseley, the relative abundance of serpulids, fish remains, bivalves and gastropods shows no relationship to the bedding rhythms.

description: The simultaneous detection of electromagnetic and gravitational wave emission from merging neutron star binaries would aid greatly in their discovery and interpretation. By studying turbulent amplification of magnetic fields in local high-resolution simulations of neutron star merger conditions, we demonstrate that magnetar-level (~10^16) G fields are present throughout the merger duration. We find that the small-scale turbulent dynamo converts 60% of the randomized kinetic energy into magnetic fields on a merger time scale. Since turbulent magnetic energy dissipates through reconnection events which accelerate relativistic electrons, turbulence may facilitate the conversion of orbital kinetic energy into radiation. If 10^-4 of the ~ 10^53 erg of orbital kinetic available gets processed through reconnection, and creates radiation in the 15-150 keV band, then the fluence at 200 Mpc would be 10^-7 erg/cm^2, potentially rendering most merging neutron stars in the advanced LIGO and Virgo detection volumes detectable by Swift BAT.

description: We present a new parallel implementation of the PINpointing Orbit Crossing-Collapsed HIerarchical Objects (PINOCCHIO) algorithm, a quick tool, based on Lagrangian Perturbation Theory, for the hierarchical build-up of Dark Matter halos in cosmological volumes. To assess its ability to predict halo correlations on large scales, we compare its results with those of an N-body simulation of a 3 Gpc/h box sampled with 2048^3 particles taken from the MICE suite, matching the same seeds for the initial conditions. Thanks to the FFTW libraries and to the relatively simple design, the code shows very good scaling properties. The CPU time required by PINOCCHIO is a tiny fraction (~1/2000) of that required by the MICE simulation. Varying some of PINOCCHIO numerical parameters allows one to produce a universal mass function that lies in the range allowed by published fits, although it underestimates the MICE mass function of FoF halos in the high mass tail. We compare the matter-halo and the halo-halo power spectra with those of the MICE simulation and find that these 2-point statistics are well recovered on large scales. In particular, when catalogs are matched in number density, agreement within ten per cent is achieved for the halo power spectrum. At scales k>0.1 h/Mpc, the inaccuracy of the Zel'dovich approximation in locating halo positions causes an underestimate of the power spectrum that can be modeled as a Gaussian factor with a damping scale of d=3 Mpc/h at z=0, decreasing at higher redshift. Finally, a remarkable match is obtained for the reduced halo bispectrum, showing a good description of nonlinear halo bias. Our results demonstrate the potential of PINOCCHIO as an accurate and flexible tool for generating large ensembles of mock galaxy surveys, with interesting applications for the analysis of large galaxy redshift surveys.

description: We present a formal tool for verification of multivariate nonlinear inequalities. Our verification method is based on interval arithmetic with Taylor approximations. Our tool is implemented in the HOL Light proof assistant and it is capable to verify multivariate nonlinear polynomial and non-polynomial inequalities on rectangular domains. One of the main features of our work is an efficient implementation of the verification procedure which can prove non-trivial high-dimensional inequalities in several seconds. We developed the verification tool as a part of the Flyspeck project (a formal proof of the Kepler conjecture). The Flyspeck project includes about 1000 nonlinear inequalities. We successfully tested our method on more than 100 Flyspeck inequalities and estimated that the formal verification procedure is about 3000 times slower than an informal verification method implemented in C++. We also describe future work and prospective optimizations for our method.

description: The Late Glacial and Holocene landscape development in the vicinity of the River Elbe near Neuhaus, Lower Saxony, was studied during geological mapping of the area. The geological and geobotanical methods used in these investigations were chosen to cope with the difficulties which arise during research on Quaternary flood plains in low country. Paleochannel fill and areas of flood-plain sediments were drilled, the lithology examined, and the sediments dated on the basis of their pollen content. No evidence was found for the existence before the Middle Ages of paleo- channels the size of the present River Elbe. Before the first measures were made to regulate the Elbe River, it was an anastomosing river system with numerous small branches. The lower parts of the flood-plain profiles are predominantly sand and the upper parts silty-clayey loam. With the construction of effective levees over the last several centuries, the flow velocity of the Elbe has increased considerably during high water periods and instead of the deposition of meadow loam, sand was deposited as natural levees. The main belt of sand dunes on the east bank of the Elbe overlies Preboreal to Boreal lake mud and is, therefore, of Holocene age.
description: Im Rahmen der geologischen Landesaufnahme wurde die spätglaziale und holozä- ne Landschaftsgenese im Gebiet der unteren Mittelelbe bei Neuhaus (Niedersachsen) untersucht. Die angewandten quartärgeologischen und geobotanischen Untersuchungsmethoden waren in besonderer Weise auf die Schwierigkeiten abgestimmt, die bei der Erforschung von Flußauen im Tiefland auftreten. Füllungen von Paläorinnen und flächenhaft abgelagerte Auensedimente wurden durch Bohrungen aufgeschlossen, sedimentologisch untersucht und pollenanalytisch datiert. Dabei konnten Paläorinnen mit den Ausmaßen der heutigen Elbe für die Zeit vor dem Mittelalter nicht nachgewiesen werden. Vor den ersten flußregulierenden Eingriffen des Menschen bestand die Elbe aus einer Vielzahl kleinerer Nebenarme und bildete ein anastomosierendes Flußsystem. Verbreitet wurde Auesand und darüber, als Hochflutsediment, schluffig-toniger Auelehm sedimentiert. Nach der wirkungsvollen Bedeichung in den letzten Jahrhunderten stieg die Fließgeschwindigkeit der Elbe bei Hochwasser so stark an, daß die Auelehmsedimentation durch die Akkumulation von Sand in Form von Uferwällen abgelöst wurde. Der Hauptdünenzug auf dem östlichen Elbufer südlich Neuhaus überlagert flächenhaft eine präboreale bis boreale Mudde und ist deshalb holozänen Alters.

description: Selection rules and interference effects in angle resolved photoemission spectra from twisted graphene bilayers are studied within a long wavelength theory for the electronic structure. Using a generic model for the interlayer coupling, we identify features in the calculated ARPES momentum distributions that are controlled by the singularities and topological character of its long wavelength spectrum. We distinguish spectral features that are controlled by single-layer singularities in the spectrum, their modification by gauge potentials in each layer generated by the interlayer coupling, and new energy-dependent interference effects that directly probe the interlayer coherence. The results demonstrate how the energy- and polarization- dependence of ARPES spectra can be used to characterize the interlayer coupling in twisted bilayer graphenes.

description: Im aufgelassenen Eisenerz-Tagebau "Morgenstern" wurde zwischen liegendem Erz und hangendem "Gaultkonglomerat" ein ca. 58 m mächtiger Schichtkomplex lithologisch und biostratigraphisch bearbeitet. Die Schichtglieder konnten anhand der begleitenden Megafauna (Belemniten, Ammoniten) und in Verbindung mit der Mikrofauna (Foraminiferen) stratigraphisch eingestuft werden. Die Foraminiferenfauna aus 93 Mikroproben wurde bearbeitet und im Sinne von MICHAEL (1974) palökologisch analysiert. Die aufgeschlossenen Schichtglieder gehören dem höchsten Mittel- Barremium (Zone des "Crioceras" sparsicosta), dem Ober-Barre- mium sowie dem Aptium an. Das Ober-Barremium konnte in die Zone des Simancyloceras stolleyi und die Zone des Parancyloceras bidentatum & P. scalare gegliedert werden. Innerhalb des Aptium konnten die beiden Unterstufen gegeneinander abgegrenzt werden; eine Ausgliederung der Zonen war hier jedoch nur teilweise und unter Vorbehalt möglich. Der aufgeschlossene Teil der Erzfazies bleibt auf das oberste Mittel-Barremium (Dachbereich des "Hauptlagers") und die stolleyi- Zone des Ober-Barremium ("Hangendes Lager" und "Zwischenlager") beschränkt; die Lager sind somit jünger als bisher von älteren Autoren (z.B. KOLBE 1962, 1970; NEUMANN 1964) angenommen wurde.

description: The photon's frequency degree of freedom, being compatible with mature telecom infrastructure, offers large potential for the stable and controllable realization of photonic quantum processing applications such as the quantum internet. The Hong–Ou–Mandel effect, as a two-photon interference phenomenon, serves as a central building block for such frameworks. A key element yet missing to enable meaningful frequency-based implementations as well as scalability in the number of processed photons, is the demonstration of the Hong–Ou–Mandel effect between independently created photons of different frequencies. The experimental implementation of bosonic and fermionic frequency domain Hong–Ou–Mandel interference between independently generated single photons is reported here, with measured visibilities of 74.31% ± 3.56% and 86.44% ± 8.27%, respectively. This is achieved through a scalable photonic frequency circuit that creates two post-selected pure single photons, which undergo frequency mixing at an electro-optic phase modulator. The system is on-the-fly reconfigurable allowing to probe bosonic and fermionic Hong–Ou–Mandel interference in the same experimental setup. The work demonstrates the versatility of frequency domain processing and its scalability toward higher photon numbers, which enables new quantum gate concepts as well as the establishment of frequency-based large-scale quantum networks. © 2021 The Authors.

description: We derive a closed-form combinatorial expression for the number of states in canonical systems with discrete energy levels. The expression results from the exact low-temperature power series expansion of the partition function. The approach provides interesting insights into basis of statistical mechanics. In particular, it is shown that in some cases the logarithm of the partition function may be considered the generating function for the number of internal states of energy clusters, which characterize system's microscopic configurations. Apart from elementary examples including the Poisson, geometric and negative binomial probability distributions for the energy, the framework is also validated against the one-dimensional Ising model.
