description: We show that the duality between F-theory and the CHL string in seven dimensions defines algebraic correspondences between K3 surfaces polarized by the rank-ten lattices $H \oplus N$ and $H\oplus E_8(-2)$. In the special case when the F-theory admits an additional anti-symplectic involution or, equivalently, the CHL string admits a symplectic one, both moduli spaces coincide. In this case, we derive an explicit parametrization for the F-theory compactifications dual to the CHL string, using an auxiliary genus-one curve, based on a construction given by André Weil.

description: In our work, we study the dynamics of a graphene Corbino disk supported by a gold mechanical resonator in the presence of a magnetic field. We demonstrate here that our graphene/gold mechanical structure exhibits a nontrivial resonance frequency dependence on the applied magnetic field, showing how this feature is indicative of the de Haas-van Alphen effect in the graphene Corbino disk. Our findings are the first evidence of dHvA effect for massless Dirac fermions. By relying on the mechanical resonances of the Au structure, our detection scheme is essentially independent of the material considered and can be applied for dHvA measurements on any conducting 2D material. In particular, the scheme is expected to be an important tool in studies of centrosymmetric transition metal dichalcogenides (TMDs) crystals, shedding new light on hidden magnetization and interaction effects.

description: Sequential sampling occurs when the entire population is not known in advance and data are obtained one at a time or in groups of units. This manuscript proposes a new algorithm to sequentially select a balanced sample. The algorithm respects equal and unequal inclusion probabilities. The method can also be used to select a spatially balanced sample if the population of interest contains spatial coordinates. A simulation study is proposed and the results show that the proposed method outperforms other methods.
Parallel Non-divergent Flow Accumulation For Trillion Cell Digital Elevation Models On Desktops Or Clusters

description: Continent-scale datasets challenge hydrological algorithms for processing digital elevation models. Flow accumulation is an important input for many such algorithms; here, I parallelize its calculation. The new algorithm works on one or many cores, or multiple machines, and can take advantage of large memories or cope with small ones. Unlike previous parallel algorithms, the new algorithm guarantees a fixed number of memory access and communication events per raster cell. In testing, the new algorithm ran faster and used fewer resources than previous algorithms, exhibiting ~30% strong and weak scaling efficiencies up to 48 cores and linear scaling across datasets ranging over three orders of magnitude. The largest dataset tested had two trillion (2*10^12) cells. With 48 cores, processing required 24 minutes wall-time (14.5 compute-hours). This test is three orders of magnitude larger than any previously performed in the literature. Complete, well-commented source code and correctness tests are available on Github.

description: Accelerated by the tremendous increase in Internet bandwidth and storage space, video data has been generated, published and spread explosively, becoming an indispensable part of today's big data. In this paper, we focus on reviewing two lines of research aiming to stimulate the comprehension of videos with deep learning: video classification and video captioning. While video classification concentrates on automatically labeling video clips based on their semantic contents like human actions or complex events, video captioning attempts to generate a complete and natural sentence, enriching the single label as in video classification, to capture the most informative dynamics in videos. In addition, we also provide a review of popular benchmarks and competitions, which are critical for evaluating the technical progress of this vibrant field.

description: In this work we answer an open question asked by Johnson--Scoville. We show that each merge tree is represented by a discrete Morse function on a path. Furthermore, we present explicit constructions for two different but related kinds of discrete Morse functions on paths that induce any given merge tree. A refinement of the used methods allows us to define notions of equivalence of discrete Morse functions on trees which give rise to a bijection between equivalence classes of discrete Morse functions and isomorphism classes of certain labeled merge trees. We also compare our results to similar ones from the literature, in particular to work by Curry.

Planck Lensing and Cosmic Infrared Background Cross-Correlation with Fermi-LAT: Tracing Dark Matter Signals in the Gamma-Ray Background

description: The extragalactic $γ$-ray background and its spatial anisotropy could potentially contain a signature of dark matter (DM) annihilation or particle decay. Astrophysical foregrounds, such as blazars and star-forming galaxies (SFGs), however, dominate the $γ$-ray background, precluding an easy detection of the signal associated with the DM annihilation or decay in the background intensity spectrum. The DM imprint on the $γ$-ray background is expected to be correlated with large-scale structure tracers. In some cases, such a cross-correlation is even expected to have a higher signal-to-noise ratio than the auto-correlation. One reliable tracer of the DM distribution in the large-scale structure is lensing of the cosmic microwave background (CMB), and the cosmic infrared background (CIB) is a reliable tracer of SFGs. We analyze Fermi-LAT data taken over 92 months and study the cross-correlation with Planck CMB lensing, Planck CIB, and Fermi-$γ$ maps. We put upper limits on the DM annihilation cross-section from the cross-power spectra with the $γ$-ray background anisotropies. The unbiased power spectrum estimation is validated with simulations that include cross-correlated signals. We also provide a set of systematic tests and show that no significant contaminations are found for the measurements presented here. Using $γ$-ray background map from data gathered over 92 months, we find the best constraint on the DM annihilation with a $1σ$ confidence level upper limit of $10^{-25}$-$10^{-24}$ cm$^{3}$ s$^{-1}$, when the mass of DM particles is between 20 and 100 GeV.

description: Diffusion Magnetic Resonance Imaging (dMRI) is an imaging technique with exquisite sensitivity to the microstructural properties of heterogeneous media. The conventionally adopted acquisition schemes involving single pulsed field gradients encode the random motion of water molecules into the NMR signal, however typically conflating the effects of different sources contributing to the water motion. Time-varying magnetic field gradients have recently been considered for disentangling such effects during the data encoding phase, opening to the possibility of adding specificity to the recovered information about the medium's microstructure. Such data is typically represented via a diffusion tensor distribution (DTD) model, thus assuming the existence of several non-exchanging compartments in each of which diffusion is unrestricted. In this work, we consider a model that takes confinement into account and possesses a diffusion time-dependence closer to that of restricted diffusion, to replace the free diffusion assumption in multidimensional diffusion MRI methods. We first demonstrate how the confinement tensor model captures the relevant signal modulations impressed by water diffusing in both free and closed spaces, for data simulated with a clinically feasible protocol involving time-varying magnetic field gradients. Then, we provide the basis for incorporating this model into two multidimensional dMRI methods, and attempt to recover a confinement tensor distribution (CTD) on a human brain dataset.

description: Gravitational-wave population studies have become more important in gravitational-wave astronomy because of the rapid growth of the observed catalog. In recent studies, emulators based on different machine learning techniques are used to emulate the outcomes of the population synthesis simulation with fast speed. In this study, we benchmark the performance of two emulators that learn the truncated power-law phenomenological model by using Gaussian process regression and normalizing flows techniques to see which one is a more capable likelihood emulator in the population inference. We benchmark the characteristic of the emulators by comparing their performance in the population inference to the phenomenological model using mock and real observation data. Our results suggest that the normalizing flows emulator can recover the posterior distribution by using the phenomenological model in the population inference with up to 300 mock injections. The normalizing flows emulator also underestimates the uncertainty for some posterior distributions in the population inference on real observation data. On the other hand, the Gaussian process regression emulator has poor performance on the same task and can only be used effectively in low-dimension cases.

description: One of the challenges of modern neuroscience is creating a "living computer" based on neural networks grown in vitro. Such an artificial device is supposed to perform neurocomputational tasks and interact with the environment when embodied in a robot. Recent studies have identified the most critical challenge, the search for a neural network architecture to implement associative learning. This work proposes a model of modular architecture with spiking neural networks connected by unidirectional couplings. We show that the model enables training a neuro-robot according to Pavlovian conditioning. The robot's performance in obstacle avoidance depends on the ratio of the weights in inter-network couplings. We show that besides STDP, critical factors for successful learning are synaptic and neuronal competitions. We use the recently discovered shortest path rule to implement the synaptic competition. This method is ready for experimental testing. Strong inhibitory couplings implement the neuronal competition in the subnetwork responsible for the unconditional response. Empirical testing of this approach requires a technique for growing neural networks with a given ratio of excitatory and inhibitory neurons not available yet. An alternative is building a hybrid system with in vitro neural networks coupled through hardware memristive connections.

Molecular biological elucidation of late tropane alkaloid biosynthesis

description: Tropane alkaloids (TA) are important and valuable secondary plant metabolites which occur in the families of Solanaceae, Erythroxylaceae, as well as Convolvulaceae, Moraceae, and Brassicaceae. These plant families produce the TAs hyoscyamine and scopolamine, cocaine, or calystegines, respectively. Due to the medicinal and pharmacological properties of hyoscyamine, scopolamine and cocaine, TA containing plants have been used for thousands of years. Even today, many drugs are derived from TAs and are used in the treatment of various diseases. Of the TAs, scopolamine is the most in demand due to its pharmacological effects and legal status. The market supply of scopolamine is still met by conventional field cultivation of Duboisia hybrids. Climate change is resulting in less-stable growth conditions for traditional farming, which limits the reliability of agricultural yields and has warranted investigation of alternative TA production processes. One proposed approach is to transfer biosynthesis into biotechnological host which would enable TA production in containable and scalable fermentative infrastructure using low-cost compounds like tropine and phenyllactic acid. All TA production approaches require profound knowledge of the biochemical pathways. To date, these pathways have not been fully elucidated, which limits their greater biotechnological application. This thesis seeks to increase the fundamental understanding of the molecular processes of the late stages of TA biosynthesis. This thesis deals with the TA biosynthesis in Duboisia plants which is highly specialized and specifically localized. The spatial distribution of TA in planta, the expression of genes involved in the biosynthesis and the TA pattern during plant development are investigated and described. Moreover, it presents investigations towards identification of the littorine synthase, a currently unknown key enzyme in TA biosynthesis. The results of this research add to our understanding of TA biosynthesis and provides important insights for the future development of alternative bio-production processes.

description: Finite volume methods (FVMs) constitute a popular class of methods for the numerical simulation of fluid flows. Among the various components of these methods, the discretisation of the gradient operator has received less attention despite its fundamental importance with regards to the accuracy of the FVM. The most popular gradient schemes are the divergence theorem (DT) (or Green-Gauss) scheme, and the least-squares (LS) scheme. Both are widely believed to be second-order accurate, but the present study shows that in fact the common variant of the DT gradient is second-order accurate only on structured meshes whereas it is zeroth-order accurate on general unstructured meshes, and the LS gradient is second-order and first-order accurate, respectively. This is explained through a theoretical analysis and is confirmed by numerical tests. The schemes are then used within a FVM to solve a simple diffusion equation on unstructured grids generated by several methods; the results reveal that the zeroth-order accuracy of the DT gradient is inherited by the FVM as a whole, and the discretisation error does not decrease with grid refinement. On the other hand, use of the LS gradient leads to second-order accurate results, as does the use of alternative, consistent, DT gradient schemes, including a new iterative scheme that makes the common DT gradient consistent at almost no extra cost. The numerical tests are performed using both an in-house code and the popular public domain PDE solver OpenFOAM.

description: The affiliation with various social groups can be a critical factor when it comes to quality of life of each individual, making such groups an essential element of every society. The group dynamics, longevity and effectiveness strongly depend on group's ability to attract new members and keep them engaged in group activities. It was shown that high heterogeneity of scientist's engagement in conference activities of the specific scientific community depends on the balance between the numbers of previous attendances and non-attendances and is directly related to scientist's association with that community. Here we show that the same holds for leisure groups of the Meetup website and further quantify individual members' association with the group. We examine how structure of personal social networks is evolving with the event attendance. Our results show that member's increasing engagement in the group activities is primarily associated with the strengthening of already existing ties and increase in the bonding social capital. We also show that Meetup social networks mostly grow trough big events, while small events contribute to the groups cohesiveness.

description: Angesichts der wachsenden klimapolitischen Herausforderungen streben viele Länder Europas bis zum Jahr 2050 eine Dekarbonisierung an, das heißt den Ausstieg aus der Nutzung fossiler Energieträger. Vor diesem Hintergrund präsentiert dieser Beitrag Prognosen des Energiebedarfs und der Energiemixe für Deutschland, Österreich und die Schweiz für das Jahr 2030 sowie einen Ausblick auf das Jahr 2050. Der Vergleich der bisherigen Energiepolitiken dieser Länder offenbart gravierende Unterschiede: Während Deutschland bislang vorwiegend auf die massive Subventionierung alternativer Stromerzeugungstechnologien gesetzt hat, war der bisherige Ansatz Österreichs eher, Energieverbrauch und Treibhausgasausstoß mit ordnungsrechtlichen Maßnahmen, insbesondere Ge- und Verboten, aber auch Subventionen, senken zu wollen. Im Gegensatz dazu setzt die Schweiz bereits seit dem Jahr 2008 auf das marktwirtschaftliche Instrument der CO2-Abgabe. Die hier präsentierten Prognosen des Energiebedarfs der drei Länder deuten darauf hin, dass vor allem Deutschland und Österreich mit einer Fortführung der bisherigen Politik das langfristige Ziel einer weitgehenden Dekarbonisierung nicht erreichen dürften, während es in der Schweiz bereits zu einem spürbaren Rückgang des Primärenergieverbrauchs gekommen ist. Vor diesem Hintergrund gewinnt die jüngst in Deutschland beschlossene CO2-Bepreisung der Emissionen in den Bereichen Verkehr und Wärme besondere Bedeutung. Auch Österreich möchte in diesen Sektoren eine CO2-Bepreisung einführen. Es bleibt allerdings abzuwarten, wie konsequent das marktwirtschaftliche Instrument der CO2-Bepreisung tatsächlich verfolgt werden wird.

description: In the present analysis a nonlinear model is discussed in order to capture the presence of several forces acting in commodity markets and the difficulty to disentangle their relative price impacts. Global commodity markets have experienced significant price swings in recent years. Analysts offer two explanations: market forces and speculative expectations, not mutually exclusive. Commodity prices seem to indicate that various factors are acting in a very complex way. We start from one specific feature: price clustering phenomenon, which is the tendency to concentrate in a number of attraction regions, preferring some values over others. Commodities are in the process of becoming mainstream. The mean-reverting class of diffusion models are not able to model the phenomenon of multiple attraction regions. In the potential function approach the price is modelled as a diffusion process governed by a potential function. A fundamental step is to fit the multimodal density of the invariant distribution. We postulate a parametric form of the distribution in the framework of finite mixture models and Expectation-Maximization algorithm. The procedure for identifying and estimating potential function and diffusion parameter is provided. Applications to crude oil and soybean prices capture the essential characteristics of the data remarkably well. An underlying assumption is that potential function and long-term volatility do not change with time. New market conditions and new attraction regions can form, changing the shape of the potential and the magnitude of long-term volatility. We investigate changes in shape of the potential, which reflects new price equilibrium levels (attraction regions) and hence new market conditions. The model allows to generate copies of the observed price series with the same invariant distribution, useful for applications requiring a large number of independent price trajectories. A goodness-of-fit test for the SDE model is provided. A numerical implementation of the analysis is provided.

description: Model-based methods are popular in derivative-free optimization (DFO). In most of them, a single model function is built to approximate the objective function. This is generally based on the assumption that the objective function is one blackbox. However, some real-life and theoretical problems show that the objective function may consist of several blackboxes. In those problems, the information provided by each blackbox may not be equal. In this situation, one could build multiple sub-models that are then combined to become a final model. In this paper, we analyze the relation between the accuracy of those sub-models and the model constructed through their operations. We develop a broad framework that can be used as a theoretical tool in model error analysis and future research in DFO algorithms design.

description: This report presents the collaborative work done between CO.RI.S.T.A. and
 HYPERION SEVEN to come up with a design for the drone that will be used
 for the FlyRadar project. This report concludes first that the optimal design t o
 be used is a classical quadcopter, and one suitable for the anticipated payload
 weight would be the TUNDRA, built by HEXADRONE. Various mechanical
 pieces will have to be built in order to mount the radar and its various antennas
 onto the drone. Finally, it was first foreseen that the use of a tether between
 the drone and a ground station could be utilized in order to power the drone
 indefinitely and have a fiber optic line to the ground, which would allow to re-
 trieve the captured data in real time and avoid to need of an on-board computer.
 However, the radar design of CO.RI.S.T.A. includes a computer small enough
 that an optical link is no longer needed. Moreover, in the aim of having t he
 drone fly in the desert (terrestrial terrains analogous to Mars), it is probably
 better to stick to the traditional way of powering a drone, i.e. a battery, making
 the need for a tether inexistent.
Quantum Protocols within Spekkens' Toy Model

description: Quantum mechanics is known to provide significant improvements in information processing tasks when compared to classical models. These advantages range from computational speeds-up to security improvements. A key question is where these advantages come from. The toy model developed by Spekkens [R. W. Spekkens PRA 75, 032110 (2012)] mimics many of the features of quantum mechanics, such as entanglement and no-cloning, regarded as being important in this regard, despite being a local hidden variable theory. In this work we study several protocols within Spekkens' toy model where we see it can also mimic the advantages and limitations shown in the quantum case. We first provide explicit proofs for the impossibility of toy bit-commitment and the existence of a toy error correction protocol and consequent $k-$threshold secret sharing. Then, defining a toy computational model based on the quantum one-way computer we prove the existence of blind and verified protocols. Importantly, these two last quantum protocols are known to achieve a better-than-classical security. Our results suggest that such quantum improvements need not arise from any Bell-type non locality or contextuality, but rather as a consequence of steering correlations.

Detecting relevant differences in the covariance operators of functional time series - a sup-norm approach

description: In this paper we propose statistical inference tools for the covariance operators of functional time series in the two sample and change point problem. In contrast to most of the literature the focus of our approach is not testing the null hypothesis of exact equality of the covariance operators. Instead we propose to formulate the null hypotheses in the form that "the distance between the operators is small", where we measure deviations by the sup-norm. We provide powerful bootstrap tests for these type of hypotheses, investigate their asymptotic properties and study their finite sample properties by means of a simulation study.

Change and Diversity in the Future of Work: From Challenges to Opportunities

description: Workplace relations and business environments will be significantly different in the coming decades. Several drivers of change ? among which demographic trends, technological progress, economics and climate change ? are transforming the way people live and work. These factors pose new challenges for companies, in front of which they are called to review their own organizations and react in order to transform the current challenges into opportunities for growth, development and competitiveness. In order to tackle these drivers of change, it is thus fundamental for companies to, first of all, fully understand which challenges and opportunities these drivers of change entail (Chapter 1); secondly, foresee how the world of work is likely to evolve in the coming decades (Chapter 2) and, finally, identify those management practices able to guarantee the competitive permanence of enterprises (Chapter 3). Failing to promptly consider and tackle them, companies risk worsening their level of competiveness and productivity and remaining out of the global market. The starting point consisted in two research questions - ?How the future of the work will look like given some drivers of change?? and ?To what extend companies are preparing themselves for the future scenario?? ? which have been addressed through the desk research, further enriched with the Delphi Technique and a set of interviews. The main results indicate that, despite being aware of the current on-going changes, not all Italian companies are fully and promptly tackling them and preparing themselves for the future scenario. Therefore, the present research project, by outlining some guidelines, tries to help companies to get prepared to the future of work and workplace relations.

description: Im ersten Teil dieser Arbeit wurden die Einflüsse von Y3+Ionen auf die Struktur sowie das Phasenverhalten und spezifische thermodynamische Parameter von Modellmembransystemen verschiedener Komplexität und Ladung untersucht. Es konnte gezeigt werden, dass die Anwesenheit dieser Ionen zu einer dichteren Lipidpackung und partieller Dehydratation der Kopfgruppenregion, sowie zu einem ausgeprägten Anstieg der Gel-zu-flüssig Phasenübergangstemperatur der Lipidmembranen führt. Dies ist auf einen gesteigerten lateralen Kompressionsdruck in der Membran zurückzuführen, welcher durch das Eindringen der Ionen in die Kopfgruppenregion und einer voraussichtlichen Koordinierung dieser an die vorliegenden Phosphatgruppen resultiert. Im zweiten Teil der Arbeit stand der Einfluss lipidierter Imidazoliumsalze auf die Struktur und das Phasenverhalten von Lipidmembranen, wie auch die Untersuchung des Fusionsinduktionspotentials dieser Moleküle im Fokus. Hierbei wurden signifikante Verringerungen der thermotropen Phasenübergangstemperatur der Membranen und starke Störungen der Lipid-Konformationsordnung sowie in der lateralen Membranordnung nachgewiesen. Weitergehend wurde der Einfluss eines weiteren, speziell zur Fusionsinduktion konstruierten lipidbasierten Imidazoliumsalzes bei verschiedenen Konzentrationen in Membranen verschiedener Komplexität untersucht. Hier wurden zur ersten Teilstudie vergleichbare Einflüsse auf das thermotrope Phasenverhalten der Membranen, jedoch geringere störende Effekte auf die laterale Membranordnung nachgewiesen. Darüber hinaus konnte unter Verwendung eines speziellen Lipid-Trägersystems für dieses Salz durch fluoreszenzmikroskopische Untersuchungen ein bestehendes Vesikel-Fusionspotential dieser Molekülklasse nachgewiesen werden. Im dritten Teil dieser Arbeit wurden Einflüsse auf die benannten Membranen der in natürlichen Zellen vorliegenden, makromolekularen Verdichtung, wie auch des hydrostatischen Druckes betrachtet. Hierzu wurde das wässrige Zwei-Phasen-System PEG/Dextran verwendet. Es konnte gezeigt werden, dass die Separation des Zwei-Phasen-Systems innerhalb des Vesikels zunächst zur intravesikulären Membranbenetzung und im späteren Verlauf in Abhängigkeit der Umgebung des Vesikels zu Ausstülpungen der ld-Domänen der Membran führt. Hierdurch wird die flüssig-flüssig Grenzflächenenergie des Zwei-Phasen-Systems reduziert und es verbleibt ein energetisch günstigerer, quasisphärischer Vesikelhauptkörper.

description: Beyond identifying genetic variants, we introduce a set of Boolean relations that allows for a comprehensive classification of the relations for every pair of variants by taking all minimal alignments into account. We present an efficient algorithm to compute these relations, including a novel way of efficiently computing all minimal alignments within the best theoretical complexity bounds. We show that for variants of the CFTR gene in dbSNP these relations are common and many non-trivial. Ultimately, we present an approach for the storing and indexing of variants in the context of a database that enables efficient querying for all these relations.
