description: We present a data-driven approach for probabilistic wind power forecasting based on conditional normalizing flow (CNF). In contrast with the existing, this approach is distribution-free (as for non-parametric and quantile-based approaches) and can directly yield continuous probability densities, hence avoiding quantile crossing. It relies on a base distribution and a set of bijective mappings. Both the shape parameters of the base distribution and the bijective mappings are approximated with neural networks. Spline-based conditional normalizing flow is considered owing to its non-affine characteristics. Over the training phase, the model sequentially maps input examples onto samples of base distribution, given the conditional contexts, where parameters are estimated through maximum likelihood. To issue probabilistic forecasts, one eventually maps samples of the base distribution into samples of a desired distribution. Case studies based on open datasets validate the effectiveness of the proposed model, and allows us to discuss its advantages and caveats with respect to the state of the art.

description: Im Laufe der vorliegenden Arbeit werden die Unterschiede des Risswachstumsverhalten von geschweißten Proben und Grundmaterial untersucht. Als Messmethoden für die Untersuchung des Rissfortschrittes dient die Direct Current Potential Drop-Methode, Dehnmessstreifen und Rastlinien. Die Materialien werden in Form von Middle Tension-Proben bei verschiedenen Lastniveaus mit einem Kraftverhältnis von 0,1 und einer Frequenz von 33 Hz zyklische belastet. Auf Grundlage der Testergebnisse wird die Direct Current Potential Drop mit der Johnson-Formel kalibriert und anschließend mit den Ergebnissen der Dehnmessstreifen und Rastlinien verglichen. Es hat sich gezeigt, dass die Johnson-Formel zuverlässig den Rissfortschritt darstellt. Der Vergleich von geschweißten Proben und Grundmaterial ergibt, dass die geschweißten Proben einen höheren Widerstand gegen Risswachstum haben, als das Grundmaterial. Der Unterschied ist besonders signifikant bei kleinen Spannungsintensitätsfaktoren. Die Ergebnisse dieser Thesis legen die Grundlage für die Untersuchung von geschweißten Proben und Grundmaterial bei niedrigen Temperaturen.
description: In this master thesis, the differences in the crack growth behavior of welded and base material is investigated. The direct current potential drop method is used to document the crack propagation. The material are tested using middle tension samples. The test is carried out with cyclic loading, a force ratio of 0.1 and a frequenze of approximately 33 Hz. Based on the test result a calibration curve is created using the Johnson formular. With the help of crack and strain gauges the calibriation curve is validated. It is shown that the Johnson formular generates an accurated description of the crack propagation. The calibration curve gives an electric current independent comparision of crack propagation and voltage drop. The conducted work in this thesis has shown that the welded material has a higher crack resistance, then the base material. The difference is especially apparent for low stress intensity factor. The findings in this thesis can be used to investigated welded and base material at low temperatures.

description: In this work, we investigate the observational and algorithmic effects on molecular cloud samples identified from position-position-velocity (PPV) space. By smoothing and cutting off the high quality data of the Milky Way Imaging Scroll Painting (MWISP) survey, we extract various molecular cloud samples from those altered data with the DBSCAN (density-based spatial clustering of applications with noise) algorithm. Those molecular cloud samples are subsequently used to gauge the significance of sensitivity, angular/velocity resolution, and DBSCAN parameters. Two additional surveys, the FCRAO Outer Galaxy Survey (OGS) and the CfA-Chile 1.2 m complete CO (CfA-Chile) survey, are used to verify the MWISP results. We found that molecular cloud catalogs are not unique and the boundary and therefore the number shows strong variation with angular resolution and sensitivity. At low angular resolution (large beam sizes), molecular clouds merge together in PPV space, while low sensitivity (high cutoffs) misses small faint molecular clouds and takes bright parts of large molecular clouds as single ones. At high angular resolution and sensitivity, giant molecular clouds (GMCs) are resolved into individual clouds, and their diffuse components are also revealed. Consequently, GMCs are more appropriately interpreted as clusters or aggregates of molecular clouds, i.e., GMCs represent molecular cloud samples themselves.

description: Gender imbalance in computing education is a well-known issue around the world. The term "leaky pipeline" is often used to describe the lack of retention of women before they progress to senior roles. Numerous initiatives have targeted the problem of the leaky pipeline in recent decades. This paper provides a comprehensive review of initiatives related to techniques used to boost recruitment and retention of women in undergraduate computing and related courses in higher education. The primary aim was to identify interventions or initiatives (which we called "actions") that have shown some effectiveness. A secondary objective was to structure our findings as a categorisation, in order to enable future action discussion, comparison and planning. A particular challenge faced in a significant portion of the work was the lack of evaluation: i.e. the assessment of the direct relationship between the initiatives and the outcomes on retention or recruitment. The actions were categorised into four groups: Policy, Pedagogy, Influence and Support and Promotion and Engagement. Policy actions need support and potentially structural change at institution level. Pedagogy actions are initiatives related to the teaching of computing courses. The Influence and Support category includes actions associated with ways to influence women to choose computing and once enrolled to support and encourage them to stay. Finally, Promotion and Engagement actions are initiatives to promote computing based courses and involve engagement and outreach activities. We present our categorisation, identifying the literature related to actions under each category and subcategory. We discuss the challenges with evaluating the direct impact of actions and outline how this work leads towards the next phase of our work - a toolkit of actions to promote retention and recruitment of women in computing undergraduate courses.

description: In this article, we provide an account of analytical results related to the Tsallis thermodynamics that have been the subject matter of a lot of studies in the field of high-energy collisions. After reviewing the results for the classical case in the massless limit and for arbitrarily massive classical particles, we compute the quantum thermodynamic variables. For the first time, the analytical formula for the pressure of a Tsallis-like gas of massive bosons has been obtained. Hence, this article serves both as a brief review of the knowledge gathered in this area, and as an original research that forwards the existing scholarship. The results of the present paper will be important in a plethora of studies in the field of high-energy collisions including the propagation of non-linear waves generated by the traversal of high-energy particles inside the quark-gluon plasma medium showing the features of non-extensivity.

description: Quantum state tomography is the experimental procedure of determining an unknown state. It is not only essential for the verification of resources and processors of quantum information but is also important in its own right with regard to the foundation of quantum mechanics. Standard methods have been elusive for large systems because of the enormous number of observables to be measured and the exponential complexity of data post-processing. Here, we propose a new scheme of quantum state tomography that requires the measurement of only three observables (acting jointly on the system and pointer) regardless of the size of the system. The system is coupled to a "pointer" of single qubit, and the wavefunction of the system is "reaped" onto the pointer upon the measurement of the system. Subsequently, standard two-state tomography on the pointer and classical post-processing are used to reconstruct the quantum state of the system. We also developed an efficient and scalable iterative maximum likelihood algorithm to estimate states from statistically incomplete data.

Interpretation of Schrodinger Equation

description: Real Wave Quantum Mechanics (RWQM) seeks to demonstrate that standard Quantum Mechanics (QM) can be derived from first principles based entirely on the interactions of real waves in an underlying universal medium. This paper extends previous work on 1 and 2 dimensional applications which used discrete linear/grid structures of entities known as Field Rotators (FRs). It is shown that FRs can be extended continuously in the 3rd dimension to give threadlike forms named FReds. Although continuous, it is shown that the 3rd dimension can be discretized to simplify calculations. Results are similar to those from Schr\"odinger's equation and can be viewed interactively from within the document or directly from the Zenodo site by downloading the appropriate html file. The meaning and role of phase in standard QM is made clear and intuitive by the RWQM approach.

The Frobenius number for sequences of triangular numbers associated with number of solutions

description: The famous linear diophantine problem of Frobenius is the problem to determine the largest integer (Frobenius number) whose number of representations in terms of $a_1,\dots,a_k$ is at most zero, that is not representable. In other words, all the integers greater than this number can be represented for at least one way. One of the natural generalizations of this problem is to find the largest integer (generalized Frobenius number) whose number of representations is at most a given nonnegative integer $p$. It is easy to find the explicit form of this number in the case of two variables. However, no explicit form has been known even in any special case of three variables. In this paper we are successful to show explicit forms of the generalized Frobenius numbers of the triples of triangular numbers. When $p=0$, their Frobenius number is given by Robles-Pérez and Rosales in 2018.

description: We propose two novel two-dimensional topological Dirac materials, planar PtN4C2 and Pt2N8C6, which exhibit graphene-like electronic structures with linearly dispersive Dirac-cone states exactly at the Fermi level. Moreover, the Dirac cone is anisotropic, resulting in anisotropic Fermi velocities and making it possible to realize orientation-dependent quantum devices. Using the first-principles electronic structure calculations, we have systemically studied the structural, electronic, and topological properties. We find that spin-orbit coupling opens a sizable topological band gap so that the materials can be classified as quantum spin Hall insulators as well as quantum valley Hall insulators. Helical edge states that reside in the insulating band gap connecting the bulk conduction and valence bands are observed. Our work not only expands the Dirac cone material family, but also provides a new avenue to searching for more two-dimensional topological quantum spin and valley Hall insulators.

description: The microbiological and physico-chemical quality of plantain pudding was evaluated during processing and storage under ambient temperature (30.5°C) for 120 h duration. Results indicates that the total viable bacteria count decreased from 1.36 x 105 cfu/g (raw sample) to 0.3 x 101 cfu/g after cooking and thereafter increase steadily to 1.05 x 108 cfu/g while the total fungi count decreased from 2.70 x 104 cfu/g to non detectable count after boiling but increase to 6.40 x 106 cfu/g at the end of the storage period. Seven bacteria genera; Bacillus, Staphylococcus, Streptococcus, Pseudomonas, Klebsiella, Lactobacillus and Escherichia coli and six fungi genera; Fusarium spp., Aspergillus spp., Penicillium spp., Alternia spp., Geotrichium spp. and Cladosporium spp. were detected and isolated. The pH decreased from 5.7 (raw sample) to 4.7 after boiling and thereafter decreased gradually till the end of the storage period while the titratable acidity increased slightly. Furthermore, the moisture content decreased steadily all through the storage period

description: New heterometallic complexes [{ZnCl(terpy)(μ-pyrazine)CuCl(terpy)}] (ClO4)2 (Zn-L1-Cu) and [{ZnCl(terpy)(μ-4,4′-bipyridyl)CuCl(terpy)}] (ClO4)2 (Zn-L2-Cu) (where terpy = 2,2′:6′,2′′-terpyridine, L1 = pyrazine, L2 = 4,4′-bipyridyl) were synthesized. The substitution reactions with biologically important nucleophiles were investigated at pH 7.4 by UV-Vis spectrophotometric method. The obtained results have shown different orders of reactivity of guanosine-5′-monophosphate (5′-GMP), inosine-5′-monophosphate (5′-IMP) and glutathione (GSH) toward heterometallic Zn(II)-L-Cu(II) complexes. Spectrophotometric titration of diaqua Zn-L-Cu complexes has shown that aqua ligands coordinated to both metal centers can exhibit different pKa values depending on the distance between them. Both synthesized complexes showed moderate antimicrobial activity against most of the tested bacterial and fungal strains. The cytotoxic activity of heteronuclear Zn-L1-Cu and Zn-L2-Cu complexes was determined on human colorectal cancer (HCT-116) and human healthy lung pleura (MRC-5) cell lines. Both complexes exerted significant cytotoxic effects, especially after 72 h (IC50 < 0.01 µM) and significantly reduced cell viability. Complexes induced a significant increase in reactive radical species which consequently induced cell death and thus lower IC50 values. As the response of the cells to an increased radical level induced by treatment, glutathione level also increased in a time and dose-dependent manner.
The theory of symmetric tensor field: from fractons to gravitons and back

description: We consider the theory of a symmetric tensor field in 4D, invariant under a subclass of infinitesimal diffeomorphism transformations, where the vector diff parameter is the 4-divergence of a scalar parameter. The resulting gauge symmetry characterizes the "fracton" quasiparticles and identifies a theory which depends on a dimensionless parameter, which cannot be reabsorbed by a redefinition of the tensor field, despite the fact that the theory is free of interactions. This kind of "electromagnetic gauge symmetry" is weaker that the original diffeomorphism invariance, in the sense that the most general action contains, but is not limited to, linearized gravity, and we show how it is possible to switch continuously from linearized gravity to a mixed phase where both gravitons and fractons are present, without changing the degrees of freedom of the theory. The gauge fixing procedure is particularly rich and rather peculiar, and leads to the computation of propagators which in the massive case we ask to be tachyonic-free, thus constraining the domain of the parameter of the theory. Finally, a closer contact to fractons is made by the introduction of a parameter related to the "rate of propagation". For a particular value of this parameter the theory does not propagate at all, and we guess that, for this reason, the resulting theory should be tightly related to the fracton excitations.

description: The present work reports the synthesis of two new zinc(II) complexes based on the 2-acetylfuranisonicotinichydrazone ligand (HL). The structure of the hydrazone and [ZnCl2(HL)]·MeOH (1) and [Zn(L)2] (2) have been elucidated by single-crystal X-ray diffraction method, physicochemical, and spectroscopic techniques. The hydrazone is a bidentate ligand, forming two new mononuclear complexes with zinc(II). Non-covalent interactions in the structures of the compounds were evaluated with Hirshfeld surface analysis, which showed the presence of hydrogen bonds in HL and 1 and also a π···π stacking interaction in 1. The antimycobacterial potentials of the compounds were tested against tuberculous and non-tuberculous mycobacteria strains.

description: Lippmann (or interferential) photography is the first and only analog photography method that can capture the full color spectrum of a scene in a single take. This technique, invented more than a hundred years ago, records the colors by creating interference patterns inside the photosensitive plate. Lippmann photography provides a great opportunity to demonstrate several fundamental concepts in signal processing. Conversely, a signal processing perspective enables us to shed new light on the technique. In our previous work, we analyzed the spectra of historical Lippmann plates using our own mathematical model. In this paper, we provide the derivation of this model and validate it experimentally. We highlight new behaviors whose explanations were ignored by physicists to date. In particular, we show that the spectra generated by Lippmann plates are in fact distorted versions of the original spectra. We also show that these distortions are influenced by the thickness of the plate and the reflection coefficient of the reflective medium used in the capture of the photographs. We verify our model with extensive experiments on our own Lippmann photographs.

description: Silicon sensors are the go-to technology for high-precision sensors in particle physics. But only recently low-noise silicon sensors with internal amplification became available. The so-called Low Gain Avalanche Detector (LGAD) sensors have been developed for applications in High Energy Physics, but lack two characteristics needed for the measurement of low-energy protons (<60 keV): a thin entrance window (in the order of tens of nm) and the efficient amplification of signals created near the sensor's surface (in a depth below 1 um). In this paper we present the so-called proton Low Gain Avalanche Detector (pLGAD) sensor concept and some results from characterization of the first prototypes of the sensor. The pLGAD is specifically designed to detect low-energy protons, and other low-penetrating particles. It will have a higher detection efficiency than non-silicon technologies, and promises to be a lot cheaper and easier to operate than competing silicon technologies.

description: Reaction of (±)-1-(2-furyl) ethanol with an equivalent Ph2PCl in the presence of Et3N proceeds in dry toluene under an argon atmosphere to give 1-(furan-2-yl)ethyl diphenylphosphinite (1) in good yield. Mononuclear complexes [dichloro(η6-p-cymene)(1-furan-2-ylethyl diphenylphosphinite)ruthenium(II)] (2), [dichloro(η6-benzene)(1-furan-2-ylethyl diphenylphosphinite)ruthenium(II)] (3), [chloro(η4-1,5-cyclooctadiene)(1-furan-2-ylethyl diphenylphosphinite)rhodium(I)] (4) and [dichloro(η5-pentamethylcyclopentadienyl)(1-furan-2-ylethyl diphenylphosphinite)iridium(III)] (5) were synthesized and characterized by microanalysis, infrared, MS, and NMR spectroscopies. The complexes are employed as catalysts in transfer hydrogenation of aromatic ketones. The complexes catalyzed reduction of a variety of aromatic ketone substrates bearing electron-withdrawing or donating substituents with very high conversion rates (up to 99%); 5 was the most efficient catalyst for the transfer hydrogenation of ketones.

description: d-Block transition metal(II)-lanthanide(III) (3d-4f) hetero‐trinuclear [Cu(II)2Ln(III)] (Ln = La and Ce) complexes [Cu2La(L)(ƞ2-NO3)3(CH3OH)2]·2CH3OH (1) and [Cu2Ce(L)(ƞ2-NO3)3(CH3OH)2]·2CH3OH (2) are described, both of which are formed by a flexible symmetrical bis(salamo)-type ligand H4L. The two 3d-4f complexes have been synthesized and characterized by elemental analyses, IR spectra and UV–Vis spectroscopy. The crystal structures of 1 and 2 were determined by single-crystal X-ray diffraction analyses. In 1 and 2, each Cu(II) ion (Cu1 or Cu2) is located in the N2O2 cavity of an (L)4− unit, while the apex is occupied by one oxygen atom of the coordinated methanol molecule, forming a penta-coordinated square pyramidal geometry. The lanthanide(III) (La or Ce) ion is located in the O6-donor coordination sphere of the completely deprotonated (L)4− unit and coordinated with the other six oxygen atoms of the three nitrate ligands to form a twelve-coordinated icosahedron. At the same time, the supramolecular structures are formed by intermolecular hydrogen bonding interactions and quantitatively determined by Hirshfeld surfaces analyses. Fluorescence properties and DFT calculations of 1 and 2 were also studied.

description: Phthalonitrile (3) including 4-(4-fluorophenyl)-5-(4-methoxyphenyl)-4H-1,2,4-triazole-3-thio substituent and its peripherally tetra substituted metal-free (4), zinc(II) (5) and lead(II) (6) phthalocyanine derivatives were prepared and characterized by FTIR, mass, 1H-NMR and 13C-NMR spectroscopic data. All studied phthalocyanines had good solubility in common organic solvents and did not aggregate. The photophysical and photochemical behaviors of the phthalocyanine complexes (4–6) were examined in DMSO to determinate their PDT potential. Singlet oxygen, fluorescence and photodegradation quantum yields showed that zinc(II) phthalocyanine (5) has potential as Type II photosensitizer for PDT applications.

description: Some of the most relevant future applications of multi-agent systems like autonomous driving or factories as a service display mixed-motive scenarios, where agents might have conflicting goals. In these settings agents are likely to learn undesirable outcomes in terms of cooperation under independent learning, such as overly greedy behavior. Motivated from real world societies, in this work we propose to utilize market forces to provide incentives for agents to become cooperative. As demonstrated in an iterated version of the Prisoner's Dilemma, the proposed market formulation can change the dynamics of the game to consistently learn cooperative policies. Further we evaluate our approach in spatially and temporally extended settings for varying numbers of agents. We empirically find that the presence of markets can improve both the overall result and agent individual returns via their trading activities.

description: Constructing high-quality character image datasets is challenging because real-world images are often affected by image degradation. There are limitations when applying current image restoration methods to such real-world character images, since (i) the categories of noise in character images are different from those in general images; (ii) real-world character images usually contain more complex image degradation, e.g., mixed noise at different noise levels. To address these problems, we propose a real-world character restoration network (RCRN) to effectively restore degraded character images, where character skeleton information and scale-ensemble feature extraction are utilized to obtain better restoration performance. The proposed method consists of a skeleton extractor (SENet) and a character image restorer (CiRNet). SENet aims to preserve the structural consistency of the character and normalize complex noise. Then, CiRNet reconstructs clean images from degraded character images and their skeletons. Due to the lack of benchmarks for real-world character image restoration, we constructed a dataset containing 1,606 character images with real-world degradation to evaluate the validity of the proposed method. The experimental results demonstrate that RCRN outperforms state-of-the-art methods quantitatively and qualitatively.

description: Degraded images commonly exist in the general sources of character images, leading to unsatisfactory character recognition results. Existing methods have dedicated efforts to restoring degraded character images. However, the denoising results obtained by these methods do not appear to improve character recognition performance. This is mainly because current methods only focus on pixel-level information and ignore critical features of a character, such as its glyph, resulting in character-glyph damage during the denoising process. In this paper, we introduce a novel generic framework based on glyph fusion and attention mechanisms, i.e., CharFormer, for precisely recovering character images without changing their inherent glyphs. Unlike existing frameworks, CharFormer introduces a parallel target task for capturing additional information and injecting it into the image denoising backbone, which will maintain the consistency of character glyphs during character image denoising. Moreover, we utilize attention-based networks for global-local feature interaction, which will help to deal with blind denoising and enhance denoising performance. We compare CharFormer with state-of-the-art methods on multiple datasets. The experimental results show the superiority of CharFormer quantitatively and qualitatively.
