description: We investigate theoretically how the ground state of a qubit-resonator system in the deep-strong coupling (DSC) regime is affected by the coupling to an environment. We employ as a variational ansatz for the ground state of the qubit-resonator-environment system a superposition of coherent states displaced in qubit-state-dependent directions. We show that the reduced density matrix of the qubit-resonator system strongly depends on how the system is coupled to the environment, i.e., capacitive or inductive, because of the broken rotational symmetry of the eigenstates of the DSC system in the resonator phase space. When the resonator couples to the qubit and the environment in different ways (for instance, one is inductive and the other is capacitive), the system is almost unaffected by the resonator-waveguide coupling. In contrast, when the two couplings are of the same type (for instance, both are inductive), by increasing the resonator-waveguide coupling strength, the average number of virtual photons increases and the quantum superposition realized in the qubit-resonator entangled ground state is partially degraded. Since the superposition becomes more fragile with increasing the qubit-resonator coupling, there exists an optimal coupling strength to maximize the nonclassicality of the qubit-resonator system.

description: Den Autorinnen der vorliegenden Masterarbeit fällt im Schulalltag auf, dass die Schülerinnen und Schüler oft mehr über ihre Defizite wissen als darüber, was sie eigentlich können und wo ihre Stärken und Begabungen liegen. Das Ziel dieser Arbeit ist es, aufzuzeigen, wie die Exekutiven Funktionen (Fokus Selbstkompetenz) im Schulalltag gefördert werden können. Die Schülerinnen und Schüler sowie die Lehrpersonen sollen auf die Wichtigkeit der Exekutiven Funktionen aufmerksam gemacht und dafür sensibilisiert werden. Zu diesem Zweck wird das Unterrichtskonzept «I am strong» entwickelt, das während 10 Wochen an zwei kognitiv sowie sozial unterschiedlichen 4. Primarklassen in Chur und Landquart durchgeführt und begleitet wird. Die zentrale Frage lautet: Inwieweit kann das Unterrichtskonzept «I am strong» die Exekutiven Funktionen (Fokus Selbstkompetenz) der Schülerinnen und Schüler fördern? Zur Überprüfung der Zielerreichung werden eine qualitative und eine quantitative Inhaltsanalyse durchgeführt. Die erhobenen Daten dokumentieren am Projektende einen Fortschritt der Schülerinnen und Schüler bezüglich ihrer Exekutiven Kompetenzen.

description: В статье исследуются вопросы управления информационной безопасностью в корпоративной предпринимательской среде в условиях активного становления и развития цифровой экономики, сопровождающегося ростом киберугроз и киберпреступности в информационном пространстве. Обеспечение информационной безопасности (ИБ) в современных условиях интенсивного развития цифровой экономики является одним из важнейших элементов корпоративного управления, поскольку в цифровую эпоху практически вся информация, которой оперирует компания, имеет ценность. В условиях цифровой экономики информационную безопасность необходимо рассматривать как непрерывный, регламентированный и прогнозируемый процесс управления, тесно взаимоувязанный с целями и задачами бизнеса компании, охватывающий зоны ответственности широкого круга структурных подразделений, и управляемый непосредственно высшим руководством. Необходимо осуществить переход от защиты ресурсов, устройств и каналов связи к защите информации как таковой, и, в первую очередь ее разграничение на личную и корпоративную. Только при таком подходе возможно обеспечить сохранность и безопасность корпоративной информации ограниченного доступа (коммерческой, банковской, налоговой тайны) и иным ценным информационным активам компаний.

title: Repertoires of architects and mountaineers. A study of two professions
Creators: name: Nydal, Anja Karina
Publisher: name: University of Kent
Year: 2022

description: This thesis studies the emergence of two crafts and argues that the ways in which a craft develops into a well defined discipline with rules, principles and techniques that underpins its practice, is dependent upon an underlying quest to master it and to become a master craftsman. It will show how mastery had several different modes but also that the repertoire of techniques that forms it has the capacity to cross both historical and disciplinary boundaries. It does so by examining two disciplines, architecture and mountaineering, and the way in which they emerged as professional practices during the sixteenth and the nineteenth centuries and also how they individually attempted to master the craft of building and the craft of climbing, respectively. The two disciplines each tell a (hi)story of anempts to master the craftsman's activity and the space within which the activity takes place but, here, the two are conjoined, not only as a metaphorical comparison but also materially through stone. Much of the content of this thesis has arisen from seeing one discipline through the eyes of another, and through weaving their (hi)stories together into one. The different modes of mastery grappled with in separate chapters represent !he ways in which the disciplines were theorised, practiced, graphically and verbally described, imagined and finally how they made use of aesthetic sensibilities, with each mode of mastery being derived from an attempt to solve spatial problems. In order to trace the identification of skills and techniques within the two disciplines, the texts investigated focus predominantly upon those books that could be defined as instruction manuals in addition to many of those that were written in the immediate lead up to the idea that practical instruction could be written. Thus the material e.xamined stems both from narrative as well as instructional texts. Through examining these different modes of mastery, a close relationship between architecture and mountaineering, and between two different centuries, is mapped out. The texts investigated include those by Antonio di Pietro Averlino (Filarete), Sebastiana Serlio, Philiben Delorme, John Ruskin, John Ball, Alfred Wills, Frederick Burlingham, Clinton Dent, George Abraham, Geoffrey Young and Kun Diemberger.

description: Chemoproteomics is a powerful method capable of detecting interactions between smallmolecules and the proteome; however, its use as a high-throughput screening method for chemical libraries has so far been limited. To address this need, we have further developed a chemoproteomics workflow to screen cysteine-reactive covalent fragments in cell lysates against the deubiquitinating (DUB) enzymes using activity-based protein profiling. By using targeted ubiquitin probes, we have addressed sensitivity and affinity limitations, enabling target identification and covalent fragment library profiling in a 96-well plate format. The use of data-independent acquisition (DIA) methods for mass spectrometry (MS) analysis combined with automated Evosep liquid chromatography (LC) reduced instrument runtimes to 21 min per sample and simplified the workflow. In this proof-of-concept study, we profile 138 covalent fragments against 57 DUB proteins and validate four hit fragments against OTUD7B and UCHL3 through site identification experiments and orthogonal biochemical activity assays.

Non-linear edge dynamics of an Integer Quantum Hall fluid

description: We report a theoretical study of the linear and nonlinear dynamics of edge excitations of an integer quantum Hall state of non-interacting fermions. New features beyond the chiral Luttinger liquid picture are anticipated to arise from the interplay of the curvature of the Landau level dispersion and of the Pauli exclusion principle. For long-wavelength perturbations, the microscopic numerical results are captured by a chiral nonlinear hydrodynamic equation including a density-dependent velocity term. In the wave-breaking regime, shock waves are found to be regularized into a complex ripple pattern by dispersion effects. Our results are of specific relevance for experiments with synthetic quantum matter, in particular ultracold atomic gases.

description: We report an {\it in-situ} scanning tunneling microscopy study of atomically thin films of CeCoIn$_5$, a $d$-wave heavy-fermion superconductor. Both hybridization and superconducting gaps are observed even in monolayer CeCoIn$_5$, providing direct evidence of superconductivity of heavy quasiparticles mediated by purely two-dimensional bosonic excitations. In these atomically thin films, $T_c$ is suppressed to nearly half of the bulk, but is similar to CeCoIn$_5$/YbCoIn$_5$ superlattices containing CeCoIn$_5$ layers with the same thickness as the thin films. Remarkably, the out-of-plane upper critical field $μ_0H_{c2\perp}$ at zero temperature is largely enhanced from those of bulk and superlattices. The enhanced $H_{c2\perp}$ well exceeds the Pauli and bulk orbital limits, suggesting the possible emergence of unusual superconductivity with parity mixing caused by the inversion symmetry breaking.

description: Body color change is one of the most important manifestations of fish adaptation to the environment. In this study, the body color change of two kinds of loach (Paramisgurnus dabryanus) with different body colors under five different background colors was first studied. It was found that the color of dorsal skin of grey-black loach changed more than that in the abdominal skin, and the L* value of the dorsal skin on the red, yellow and white backgrounds changed significantly (P < 0.05). Compared with the grey-black loach, the body color of golden loach changed less, and the L* value of the back skin and the abdomen skin did not change significantly (P > 0.05). Furthermore, the dynamic change characteristics and adaptive mechanism of body color in different background colors was studied in a black-white background conversion model. The results showed that the greyscale color decreased from 72.33 ± 2.55 to 38.22 ± 2.33, the melanocytes changed from dendritic to mass, and the L* value of the back skin increased significantly (P < 0.05) after transferring the loach from a black background to a white background. The concentration of plasma ATCH decreased significantly (P < 0.05), and that of MCH increased significantly (P < 0.05). When transferring the loach from a white background to a black background, these indicators showed an opposite trend. This study provides a scientific basis for healthy farming of loach and understanding the background color adaptation mechanism of fish

description: Socialization in online communities allows existing members to welcome and recruit newcomers, introduce them to community norms and practices, and sustain their early participation. However, socializing newcomers does not come for free: in large communities, socialization can result in a significant workload for mentors and is hard to scale. In this study we present results from an experiment that measured the effect of a lightweight socialization tool on the activity and retention of newly registered users attempting to edit for the first time Wikipedia. Wikipedia is struggling with the retention of newcomers and our results indicate that a mechanism to elicit lightweight feedback and to provide early mentoring to newcomers improves their chances of becoming long-term contributors.

High-Degree Splines from Discrete Fourier Transforms: Robust Methods to Obtain the Boundary Conditions

description: Computing accurate splines of degree greater than three is still a challenging task in today's applications. In this type of interpolation, high-order derivatives are needed on the given mesh. As these derivatives are rarely known and are often not easy to approximate accurately, high-degree splines are difficult to obtain using standard approaches. In Beaudoin (1998), Beaudoin and Beauchemin (2003), and Pepin et al. (2019), a new method to compute spline approximations of low or high degree from equidistant interpolation nodes based on the discrete Fourier transform is analyzed. The accuracy of this method greatly depends on the accuracy of the boundary conditions. An algorithm for the computation of the boundary conditions can be found in Beaudoin (1998), and Beaudoin and Beauchemin (2003). However, this algorithm lacks robustness since the approximation of the boundary conditions is strongly dependant on the choice of $θ$ arbitrary parameters, $θ$ being the degree of the spline. The goal of this paper is therefore to propose two new robust algorithms, independent of arbitrary parameters, for the computation of the boundary conditions in order to obtain accurate splines of any degree. Numerical results will be presented to show the efficiency of these new approaches.

description: The adsorption of organic molecules coumarin and the donor-$π$-acceptor type tetrahydroquinoline (C2-1) on anatase (101) and (001) nanowires have been investigated using screened Coulomb hybrid density functional theory calculations. While coumarin forms single bond with the nanowire surface, C2-1 additionally exhibits bidentate mode giving rise to much stronger adsorption energies. Nonlinear solvation effects on the binding characteristics of the dye chromophores on the nanowire facets have also been examined. These two dye sensitizers show different electronic charge distributions for the highest occupied and the lowest unoccupied molecular states. We studied the electronic structures in terms of the positions of the band edges and adsorbate related band gap states and their effect on the absorption spectra of the dye-nanowire combined systems. These findings were interpreted and discussed from the view point of better light harvesting and charge separation as well as in relation to more efficient charge carrier injection into the semiconductor nanowire.

description: Das Anliegen der vorliegenden Arbeit ist die Vermittlung des antiken Verhältnisses zwischen Mensch und natürlicher Umgebung im Lateinunterricht sowie ein Vergleich mit der heutigen Situation. Die Ergründung jenes Verhältnisses erfolgt am Beispiel des antiken Bergbaus, eines besonders anschaulichen Feldes der Umweltgeschichte. Denn es weist ein hohes Maß an Aktualität auf sowie ein großes Potential, aus der Beschäftigung mit ihm Erkenntnisse für die Gegenwart zu gewinnen. 
Vorgelegt wird eine Unterrichtskonzeption, die zugleich eine Analyse der menschlichen Naturwahrnehmung vornimmt. Zunächst wird dabei die Heterogenität dieser Wahrnehmung in der Antike aufgezeigt und in Bezug zur damals geäußerten Kritik am Bergbau gesetzt. Anschließend werden folgende Teilaspekte behandelt: 1. die antike bergbauliche Technik und Praxis, 2. die damals herrschenden Arbeitsbedingungen, 3. die gewonnenen Rohstoffe und ihre Verwendung sowie 4. die Folgen des Bergbaus für Mensch und Umwelt. Der didaktische Teil besteht aus einem Entwurf für drei Doppelstunden. Er enthält die Lehrmaterialien, die jeweiligen Erläuterungen und den Erwartungshorizont.

description: We develop a theory of persistent homology for directed simplicial complexes which detects persistent directed cycles in odd dimensions. We relate directed persistent homology to classical persistent homology, prove some stability results, and discuss the computational challenges of our approach. Our directed persistent homology theory is motivated by homology with semiring coefficients: by explicitly removing additive inverses, we are able to detect directed cycles algebraically.

description: We demonstrate theoretically that by placing a ferromagnetic particle between a nitrogen-vacancy (NV) magnetometer and a target spin, the magnetometer sensitivity is increased dramatically. Specifically, using materials and techniques already experimentally available, we find that by taking advantage of the ferromagnetic resonance the minimum magnetic moment that can be measured is smaller by four orders of magnitude in comparison to current state-of-the-art magnetometers. As such, our proposed setup is sensitive enough to detect a single nuclear spin at a distance of $30$~nm from the surface within less than one second of data acquisition at room temperature. Our proposal opens the door for nanoscale NMR on biological material under ambient conditions.

description: Massive outflows driven by active galactic nuclei (AGN) are widely recognised to play a key role in the evolution of galaxies, heating the ambient gas, expelling it from the nuclear regions, and thereby affecting the star formation histories of the galaxy bulges. It has been proposed that the powerful jets of relativistic particles launched by some AGN can both accelerate and heat the molecular gas, which often dominates the mass budgets of the outflows. However, clear evidence for this mechanism in the form of detailed associations between the molecular gas kinematics and features in the radio-emitting jets has been lacking. Here we show that the warm molecular hydrogen gas in the western radio lobe of the Seyfert galaxy IC5063 is moving at high velocities - up to 600 km/s - relative to the galaxy disk. This suggests that the molecules have been accelerated by fast shocks driven into the interstellar medium (ISM) by the expanding radio jets. These results demonstrate the general feasibility of accelerating molecular outflows in fast shocks driven by AGN.

description: Magnetic fusion devices operate at regimes characterized by extremely high temperatures and low densities, for which the charged particles motion is well described by classical mechanics. This is not true, however, for solid-state metallic objects: their density approaches $10^{28} \rm m^{-3}$, so that the average interparticle distance is shorter than the de Broglie wavelength, which characterizes the spread of the electron wave function. Under these conditions, the conduction electrons behave as a true quantum plasma even at room temperature. Here, we shall illustrate the impact of quantum phenomena on the electron dynamics in metallic objects of nanometric size, particularly thin metallic films excited by short laser pulses. Further, we will discuss more recent results on regimes that involve spin and relativistic effects.

description: We consider a continuum model of electrical signals in the human cortex, which takes the form of a system of semilinear, hyperbolic partial differential equations for the inhibitory and excitatory membrane potentials and the synaptic inputs. The coupling of these components is represented by sigmoidal and quadratic nonlinearities. We consider these equations on a square domain with periodic boundary conditions, in the vicinity of the primary transition from a stable equilibrium to time-periodic motion through an equivariant Hopf bifurcation. We compute part of a family of standing wave solutions, emanating from this point.

description: Quality control and normalizationQuality control (QC) is essential to ensure the reliability of downstream analyses. Cells were filtered based on gene counts, retaining those with counts between 500 and 8,000, and excluding cells with mitochondrial RNA (mtRNA) content exceeding 10%, to eliminate those likely to be stressed or damaged. To address technical biases and enhance biological interpretations, normalization and scaling were conducted following QC using Seurat v4.1.1, ensuring that the downstream analysis is driven by relevant biological phenomena and not technical noise. The “NormalizeData” function normalized gene expression levels across all cells, and the “ScaleData” function scaled the normalized data to facilitate the identification of biologically relevant genes.Doublet RemovalDoublets were removed using the "DoubletFinder" package. The process involved performing principal component analysis (PCA) on the normalized data to achieve dimensionality reduction, generating simulated doublet data to match the expected doublet rate, and integrating the simulated doublet data with the original dataset. Each cell was then assigned a doublet score using a k-nearest neighbors (k-NN) classifier. We utilized the “doubletFinder_v3” function to label potential doublet cells (with pN set to 0.25). Based on a threshold reflecting the expected doublet rate (5%), doublets were identified and removed from the dataset.Integration, Dimensionality reduction and ClusteringBatch effects between samples were corrected using the Harmony algorithm to ensure that comparisons were not influenced by technical variability. Once integrated, dimensionality reduction and clustering were performed to summarize expression patterns and cluster cells. The top 2,500 variable genes were identified using the “FindVariableFeatures” function. PCA was performed on these genes, and the first 12 principal components were used for clustering cells with the “FindClusters” function. To visualize cellular clusters in two dimensions, Unified Manifold Approximation and Projection (UMAP) was employed.Cell-type annotationDifferentially expressed genes (DEGs) were identified to understand functional differences between clusters. The “FindMarkers” function of Seurat, employing the Wilcoxon likelihood-ratio test with default parameters, was used for DEG identification. Cell type annotation was then performed to categorize cell populations. Canonical marker genes identified among the DEGs were integrated and supported by relevant literature.
