description: A method of a Convolutional Neural Networks (CNN) for image classification with image preprocessing and hyperparameters tuning was proposed. The method aims at increasing the predictive performance for COVID-19 diagnosis while more complex model architecture. Firstly, the CNN model includes four similar convolutional layers followed by a flattening and two dense layers. This work proposes a less complex solution based on simply classifying 2D-slices of Computed Tomography scans. Despite the simplicity in architecture, the proposed CNN model showed improved quantitative results exceeding state-of-the-art when predicting slice cases. The results were achieved on the annotated CT slices of the COV-19-CT-DB dataset. Secondly, the original dataset was processed via anatomy-relevant masking of slice, removing none-representative slices from the CT volume, and hyperparameters tuning. For slice processing, a fixed-sized rectangular area was used for cropping an anatomy-relevant region-of-interest in the images, and a threshold based on the number of white pixels in binarized slices was employed to remove none-representative slices from the 3D-CT scans. The CNN model with a learning rate schedule and an exponential decay and slice flipping techniques was deployed on the processed slices. The proposed method was used to make predictions on the 2D slices and for final diagnosis at patient level, majority voting was applied on the slices of each CT scan to take the diagnosis. The macro F1 score of the proposed method well-exceeded the baseline approach and other alternatives on the validation set as well as on a test partition of previously unseen images from COV-19CT-DB dataset.

description: Radical cations of diamondoids are important intermediates in their functionalization reactions in polar solvents. To explore the role of the solvent at the molecular level, we characterize herein microhydrated radical cation clusters of the parent molecule of the diamondoid family, adamantane (C10H16, Ad), by infrared photodissociation (IRPD) spectroscopy of mass-selected [Ad(H2O)n=1–5]+ clusters. IRPD spectra of the cation ground electronic state recorded in the CH/OH stretch and fingerprint ranges reveal the first steps of this fundamental H-substitution reaction at the molecular level. Analysis of size-dependent frequency shifts with dispersion-corrected density functional theory calculations (B3LYP-D3/cc-pVTZ) provides detailed information about the acidity of the proton of Ad+ as a function of the degree of hydration, the structure of the hydration shell, and the strengths of the CH⋯O and OH⋯O hydrogen bonds (H-bonds) of the hydration network. For n = 1, H2O strongly activates the acidic C–H bond of Ad+ by acting as a proton acceptor in a strong CH⋯O ionic H-bond with cation-dipole configuration. For n = 2, the proton is almost equally shared between the adamantyl radical (C10H15, Ady) and the (H2O)2 dimer in a strong C⋯H⋯O ionic H-bond. For n ≥ 3, the proton is completely transferred to the H-bonded hydration network. The threshold for this size-dependent intracluster proton transfer to solvent is consistent with the proton affinities of Ady and (H2O)n and confirmed by collision-induced dissociation experiments. Comparison with other related microhydrated cations reveals that the acidity of the CH proton of Ad+ is in the range of strongly acidic phenol+ but lower than for cationic linear alkanes such as pentane+. Significantly, the presented IRPD spectra of microhydrated Ad+ provide the first spectroscopic molecular-level insight of the chemical reactivity and reaction mechanism of the important class of transient diamondoid radical cations in aqueous solution.
title: Aspects of Weber Electrodynamics
Creators: name: Baumgaertel, Christof
Publisher: name: University of Liverpool Repository
Year: 2022

description: This study investigates certain aspects of the direct-action electrodynamic theory of Wilhelm Eduard Weber with a special focus on selected experimental topics. Weber electrodynamics is an alternative to electromagnetic field theory and Maxwell’s equations that can describe a wide range of electric and magnetic phenomena and in addition provides a basis for other branches of physics by explaining phenomena beyond the scope of electromagnetism. It is of interest to investigate the validity of the theory and if it can be a viable alternative to existing approaches, exploring its modelling capabilities and determining boundaries of its applicability. Further, it is sought what experimental evidence can be obtained in support of either theory and if there are associated benefits and drawbacks to the respective theories.\\ The literature analysis gives a brief introduction to both the standard theory of fields and that of Weber. It then continues to review the capabilities of Weber’s electrodynamics and shows how it has been used in the literature as an explanation for several phenomena, including, but not limited to, electricity and magnetism. In addition, limitations that exist in Weber’s electrodynamics are also addressed and criticism the theory has faced historically re-explored.\\ Experiments have been performed encompassing electron beam deflection and unipolar induction, which also investigates the movement of a rotating magnetic field. The experimental results are used to juxtapose predicted results from Weber as well as a standard field model to measured data, enabling the validity of the theories to be assessed within the constraints of the experiments.\\ The results of this work show that, in the low velocity limit, Weber's theory and Maxwell's are similar, if not the same. For the experiments performed with electron beam deflection and unipolar induction, both theories are found to arrive at the same results, qualitatively as well as quantitatively. Further to good agreement between experimentally observed quantities and predictions from the theoretical models, open questions about unipolar induction could be answered and new insight was gained regarding the working mechanism of the unipolar induction phenomenon.\\ Although agreement is found between Weber’s theory and these specific experiments, the theory is not without limitations and still needs further development. The similarity between Weber’s and Maxwell’s theories are discussed and extended to fundamental concepts such as the ether, particles and fields; Weber’s theory as a particle-based theory is considered as a promising approach to gain new insight into some of the fundamental concepts of physics.

description: We employed the ESO MPI wide-field camera and obtained deep images in the VIc pass-bands in the region of the IC 2944/2948 complex (l ~ 294; b ~ -1), and complemented them with literature and archival data. We used this material to derive the photometric, spectroscopic and kinematic properties of the brightest (V < 16) stars in the region. The VI deep photometry on the other end, helped us to unravel the lower main sequence of a few, possibly physical, star groups in the area. Our analysis confirmed previous suggestions that the extinction toward this line of sight follows the normal law (Rv = 3.1). We could recognize B-type stars spread in distance from a few hundred pc to at least 2 kpc. We found two young groups (age ~ 3 Myr) located respectively at about 2.3 and 3.2 kpc from the Sun. They are characterized by a significant variable extinction (E(B-V) ranging from 0.28 to 0.45 mag), and host a significant pre-main sequence population. We computed the initial mass functions for these groups and obtained slopes Gamma from -0.94 to -1.02 (e_Gamma = 0.3), in a scale where the classical Salpeter law is -1.35. We estimated the total mass of both main stellar groups in ~ 1100$ and ~ 500$ Mo, respectively. Our kinematic analysis indicated that both groups of stars deviate from the standard rotation curve of the Milky Way, in line with literature results for this specific Galactic direction. Finally, along the same line of sight we identified a third group of early-type stars located at ~ 8 kpc from the Sun. This group might be located in the far side of the Sagittarius-Carina spiral arm.

description: Farnesyltransferase inhibitors (FTIs) are a class of oral anti-cancer drugs currently tested in phase I-II clinical trials for treatment of hematological malignancies. The in vitro effects of various FTIs (alpha-hydroxyfarnesylphosphonic acid, manumycin-A and SCH66336) were tested on CD34+ KG1a cell line and in primary acute myeloid leukemia (AML) cells from 64 patients. By cell viability and clonogeneic methylcellulose assays, FTIs showed a significant inhibitory activity in CD34+ KG1a and primary bone marrow (BM) leukemic cells from 56% of AML patients. FTIs also induced activation of caspase-3 and Fas-independent apoptosis, confirmed by the finding that inhibition of caspase-8 was not associated with the rescue of FTItreated cells. We concluded that other cellular events induced by FTIs may trigger activation of caspase-3 and subsequent apoptosis, but the expression of proapoptotic molecules, as Bcl-2 and Bcl-XL, and antiapoptotic, as Bcl-X(s), were not modified by FTIs. By contrast, expression of inducible nitric oxide synthase (iNOS) was increased in FTI-treated AML cells. Our results suggest a very complex mechanism of action of FTIs that require more studies for a better clinical use of the drugs alone or in combination in the treatment of hematological malignancies.

Dazu hat das Bayerische Forschungsinstitut für Digitale Transformation (bidt) zwei kurze Onlinebefragungen Ende März 2020 und Mitte Juni 2020 unter jeweils rund 1.500 erwachsenen berufstätigen Internetnutzerinnen und -nutzern durchgeführt. Die Ergebnisse zeigen u. a., wie häufig Befragte vor und während der Coronakrise von zu Hause aus arbeiteten und welche Gründe es zuvor für die Nicht-Nutzung von Homeoffice gab. Ferner wurde erhoben, wie gut die Arbeitgeberseite auf die Ausweitung von Homeoffice vorbereitet war und ob Schwierigkeiten bei der Nutzung der im Homeoffice eingesetzten Technik vorlagen. Weitere Fragen betrafen die Zufriedenheit mit der Situation bei der Arbeit von zu Hause aus sowie den Wunsch nach mehr Homeoffice und die Einschätzung der Entwicklung von Homeoffice-Angeboten nach der Krise.
description: This study provides insights into the prevalence and practice of home office in Germany in the wake of the coronavirus pandemic. Central to this, the Bavarian Research Institute for Digital Transformation (bidt) conducted two short online surveys at the end of March 2020 and in mid-June 2020. Each one collected around 1,500 responses from working
adult Internet users. The results show how often respondents worked from home before and during the coronavirus crisis as well as the reasons given for not having worked in home office before. Also investigated was how well employers were prepared for the increase in home office working, and whether there were any difficulties associated with the technology required to work from home. Other questions captured the satisfaction levels of people working from home as well as their desire to do so more often and their estimation of how opportunities to work from home might develop once the pandemic was over.

description: We explain the use of quantum process calculus to describe and analyse linear optical quantum computing (LOQC). The main idea is to define two processes, one modelling a linear optical system and the other expressing a specification, and prove that they are behaviourally equivalent. We extend the theory of behavioural equivalence in the process calculus Communicating Quantum Processes (CQP) to include multiple particles (namely photons) as information carriers, described by Fock states or number states. We summarise the theory in this paper, including the crucial result that equivalence is a congruence, meaning that it is preserved by embedding in any context. In previous work, we have used quantum process calculus to model LOQC but without verifying models against specifications. In this paper, for the first time, we are able to carry out verification. We illustrate this approach by describing and verifying two models of an LOQC CNOT gate.

description: A fundamental question about the early evolution of low-mass protostars is when circumstellar disks may form. High angular resolution observations of molecular transitions in the (sub)millimeter wavelength windows make it possible to investigate the kinematics of the gas around newly-formed stars, for example to identify the presence of rotation and infall. IRAS 16293-2422 was observed with the extended Submillimeter Array (eSMA) resulting in subarcsecond resolution (0.46" x 0.29", i.e. $\sim$ 55 $\times$ 35~AU) images of compact emission from the C$^{17}$O (3-2) and C$^{34}$S (7-6) transitions at 337~GHz (0.89~mm). To recover the more extended emission we have combined the eSMA data with SMA observations of the same molecules. The emission of C$^{17}$O (3-2) and C$^{34}$S (7-6) both show a velocity gradient oriented along a northeast-southwest direction with respect to the continuum marking the location of one of the components of the binary, IRAS16293A. Our combined eSMA and SMA observations show that the velocity field on the 50--400~AU scales is consistent with a rotating structure. It cannot be explained by simple Keplerian rotation around a single point mass but rather needs to take into account the enclosed envelope mass at the radii where the observed lines are excited. We suggest that IRAS 16293-2422 could be among the best candidates to observe a pseudo-disk with future high angular resolution observations.

We will argue that these types of behaviour could be perfectly natural in some approaches to the next physical level beyond classical general relativity.

description: Improving the efficiency of mining is inextricably linked with the improvement of explosive technologies. The quality of the rock mass preparation for further processing and obtaining the final product depends on ensuring an increase in the pace and efficiency of economic development of mining countries. The analysis of promising methods for improving explosive preparation of rock mass showed that the main direction is inextricably linked with the use of modern physical fields aimed at intensifying detonation processes. One of these areas is the use of the cumulative effect. The authors developed the design of the borehole explosive charge (EC) using a cumulative effect, which allows to lower the bottom of the ledge and reduce the cost of drilling and blasting. This design of the charge due to the location of the explosive charge directly above the zone of the bottom of the ledge will increase the effect of the explosion on it. The cumulative recess forms a stream, which creates a shock wave directed down and away from the well. In its turn, the stress waves from the cumulative charge directed upward produce additional crushing of the overlying rocks. The direction of the energy of one part of the explosive charge to the lower part of the well increases the time of the explosion on the array and creates two waves of stresses that affect the entire array. The proposed technology also provides for the dispersion of the explosive charge in an inert gap, the lower element of which is made of explosives, corresponding to the strength characteristics of the rocks of the base zone of the ledge, and the upper one should correspond to the exclusivity category of the rocks constituting the ledge. The location of a cumulative funnel in the bottom of the well affects the intensity of explosive destruction of rocks. The effective parameters of the cumulative funnel in the design of the borehole explosive charge are determined.

description: Orbital monitoring of M-type binaries is essential for constraining their fundamental properties. This is particularly useful in young systems, where the extended pre-main sequence evolution can allow for precise isochronal dating. Here, we present the continued astrometric monitoring of the more than 200 binaries of the AstraLux Large Multiplicity Survey, building both on our previous work, archival data, and new astrometric data spanning the range of 2010-2012. The sample is very young overall -- all included stars have known X-ray emission, and a significant fraction (18%) of them have recently also been identified as members of young moving groups in the Solar neighborhood. We identify ~30 targets that both have indications of being young and for which an orbit either has been closed or appears possible to close in a reasonable timeframe (a few years to a few decades). One of these cases, GJ 4326, is however identified as probably being substantially older than has been implied from its apparent moving group membership, based on astrometric and isochronal arguments. With further astrometric monitoring, these targets will provide a set of empirical isochrones, against which theoretical isochrones can be calibrated, and which can be used to evaluate the precise ages of nearby young moving groups.

Galaxy And Mass Assembly (GAMA): Bulge-disk decomposition of KiDS and VIKING data in the nearby universe

description: In this thesis, we derive a catalogue of robust structural parameters for the components of a large sample of nearby GAMA galaxies while at the same time contributing to the advancement of image analysis, surface brightness fitting and post-processing routines for quality assurance in the context of automated large-scale bulge-disk decomposition studies. The sample consists of 13096 galaxies at redshifts z < 0.08 with imaging data from the Kilo-Degree Survey and the VISTA Kilo-Degree INfrared Galaxy survey spanning the optical and near-infrared. We fit three models to the surface brightness distribution of each galaxy in each band: a single Sérsic model, a Sérsic plus exponential and a point source plus exponential. The fitting is performed with a fully automated Markov-chain Monte Carlo (MCMC) analysis using the Bayesian two-dimensional profile fitting code ProFit. All preparatory work is carried out using the image analysis package ProFound. After fitting the galaxies, we perform model selection and flag galaxies for which none of our models are appropriate, mainly mergers and irregular galaxies. The fit quality is assessed by visual inspections, comparison to previous works, comparison of independent fits of galaxies in the overlap regions between KiDS tiles and bespoke simulations. The latter two are also used for a detailed investigation of systematic error sources. We find that our fit results are robust across various galaxy types and image qualities with minimal biases. Errors given by the MCMC underestimate the true errors typically by factors 2-3. Automated model selection criteria are accurate to > 90 % as calibrated by visual inspection of a subsample of galaxies. We also present g-r component colours and the corresponding colour-magnitude diagram, consistent with previous works despite our increased fit flexibility. All results are integrated into the GAMA database.

Sobolev Inequalities and Convergence For Riemannian Metrics and Distance Functions

Subjects: subject: Differential Geometry (math.DG)

description: If one thinks of a Riemannian metric, $g_1$, analogously as the gradient of the corresponding distance function, $d_1$, with respect to a background Riemannian metric, $g_0$, then a natural question arises as to whether a corresponding theory of Sobolev inequalities exists between the Riemannian metric and its distance function. In this paper we study the sub-critical case $p < \frac{m}{2}$ and show a Sobolev inequality exists where an $L^{\frac{p}{2}}$ bound on a Riemannian metric implies an $L^q$ bound on its corresponding distance function. We then use this result to state a convergence theorem and show how this theorem can be useful to prove geometric stability results by proving a version of Gromov's conjecture for tori with almost non-negative scalar curvature in the conformal case. Examples are given to show that the hypotheses of the main theorems are necessary.

description: Ein Trauma führt zu einer Veränderung der Hirnaktivität, wodurch die Funktionsweise des
Gehirns nachhaltig beeinträchtigt wird. Nach einer Traumatisierung erfolgt eine
Neubewertung sämtlicher bisheriger Informationen und Bewältigungsstrategien. Im
Folgenden wird seitens der Autorinnen Adriana Caso und Paola Eggenschwiler dargelegt, auf
welche Art und Weise Kinder und Jugendliche, die ein Trauma erlebt haben, adäquat
unterstützt, befähigt und verstanden werden können. Die Beantwortung der Fragestellung
erfolgt unter Berücksichtigung verschiedener Aspekte. Einerseits wird der Begriff "Trauma"
definiert, andererseits werden die Ursachen und Entstehungsbedingungen von Traumata bei
Kindern und Jugendlichen erörtert. Zudem werden die Herausforderungen in der
Bezugspersonenarbeit beleuchtet. Dies geschieht im Rahmen einer Literaturrecherche. Die
Bachelorarbeit behandelt Aspekte über die Themen Bindung, Beziehung, Kooperation sowie
speziell über Trauma in der Kindheit und Bezugspersonenarbeit. Im sechsten Kapitel erfolgt
eine Vorstellung konkreter Methoden für die traumapädagogische Arbeit, welche im Alltag
Anwendung finden können.
Der Eintritt von traumatisierten Kindern und Jugendlichen in stationäre Einrichtungen stellt
die Professionellen der Sozialen Arbeit, das Umfeld der Klient*innen sowie die Kinder und
Jugendlichen selbst oftmals vor Herausforderungen. Die Gestaltung einer fruchtbaren
Zusammenarbeit im Alltag erfordert ein hohes Maß an Fachwissen, Einfühlungsvermögen
sowie die Anwendung gezielter Methoden. Die nachfolgende Bachelorarbeit mit dem Titel
"Traumaarbeit in der stationären Kinder- und Jugendhilfe – Methoden für Fachkräfte" verfolgt
das Ziel, Fachkräfte in ihrer Arbeit zu unterstützen und das bestehende Wissen über Traumata
und dessen Folgen zu erweitern.

description: Wie Menschen die digitale Transformation erleben, ist von fundamentaler Bedeutung
für die erfolgreiche Gestaltung des gesellschaftlichen Wandels. Ohne das Vertrauen der
Menschen, aber auch ohne ihr Engagement wird der Weg in eine digitale Gesellschaft
nicht gelingen. Zur Frage, wie die Menschen die digitale Transformation erleben, zeichnet
die bisherige Forschung kein einheitliches Bild. Wie ein Mantra spukt stattdessen
die Rede von einer neuen „German Angst“ durch die öffentliche Debatte. In der Studie
#UmbruchErleben haben wir mit den Menschen selbst über ihre Erfahrungen gesprochen.
Unsere Interviews zeigen, dass sie angesichts der Digitalisierung keineswegs in
Angststarre verfallen. Sie ringen vielmehr um ihre Zukunft und eine positive Entwicklung
der digitalen Transformation. Statt die Menschen weiterhin als „Angsthasen“ zu
behandeln, gilt es diesen Weg in die digitale Gesellschaft als einen gemeinsamen
produktiven Lernprozess zu gestalten, der Lust auf Zukunft macht.
description: How people experience digital transformation is of fundamental importance for the
successful shaping of social change. Without people’s trust and indeed their commitment,
the path to a digital society will be rocky and problematic. Previous research does not
paint a consistent picture of how people experience digital transformation, with
expressions of a new “German Angst” haunting public debate like a mantra. In the study
“Living Through a Period of Change” we talked to people about their experiences and
interviews reveal that the idea of fear in the face of digitalisation is something of a myth.
Hence, instead of continuing to treat people like ‘headless chickens’, this path towards a
digital society should rather be treated as a joint productive learning process that whets
people’s appetites for the future.
