description: The floating leaves of the aquatic fern Salvinia molesta are covered by superhydrophobic hairs (=trichomes) which are shaped like egg-beaters. These trichomes cause high water repellency and stable unwettability if the leaf is immersed. Whereas S. molesta hairs are technically interesting, there remains also the question concerning their biological relevance. S. molesta has its origin in Brazil within a region exposed to intense rainfall which easily penetrates the trichome cover. In this study, drop impact on leaves of S. molesta were analysed. The largest portion of the kinetic energy of a rain drop is absorbed by elastic responses of the trichomes and the leaf. Although rain water is mostly repelled, it turned out that the trichomes hamper swift shedding of rain water and some residual water can remain below the ‘egg-beaters’. Drops rolling over the trichomes can, however, ‘suck up’ water trapped beneath the egg-beaters because the energetic state of a drop on top of the trichomes is—on account of the superhydrophobicity of the hairs—much more favourable. The trichomes may therefore be beneficial during intense rainfall, because they absorb some kinetic energy and keep the leaf base mostly free from water.

description: It is well-known that any quantum gate can be decomposed into the universal gate set {T, H, CNOT}, and recent results have shown that each of these gates can be implemented using a dynamic quantum walk, which is a continuous-time quantum walk on a sequence of graphs. This procedure for converting a quantum gate into a dynamic quantum walk, however, can result in long sequences of graphs. To alleviate this, in this paper, we develop a length-3 dynamic quantum walk that implements any single-qubit gate. Furthermore, we extend this result to give length-3 dynamic quantum walks that implement any single-qubit gate controlled by any number of qubits. Using these, we implement Draper's quantum addition circuit, which is based on the quantum Fourier transform, using a dynamic quantum walk.

Fuel processor - PEM fuel cell systems for energy generation
Creators: name: Menna, Laura
Publisher: name: Università degli Studi di Napoli Federico II
Year: 2010

description: In the last few years, increasing attention has been paid to PEM fuel cells, as promising device for decentralized energy production, both in stationary and automotive field, thanks to high compactness, low weight (high power-to-weight ratio), high modularity, good efficiency and fast start-up and response to load changes. The high efficiencies that can be obtained with a PEM fuel cell, however, require a high purity hydrogen feed at the anode. Hydrogen, though, is not a primary source, but it is substantially an energy carrier, that can be stored, transported and employed as gaseous fuel, however, it needs to be produced from other sources. The main hydrogen source is actually represented by hydrocarbons, through classical Steam Reforming or Partial Oxidation industrial scale processes. However, the limitation of hydrogen storage and transport due to its chemico-physical properties has pushed toward the concept of decentralized hydrogen production; in this way, the hydrogen source, such as methane, is distributed through pipelines to the small-scale plant, installed nearby the users, and the hydrogen produced in situ is fed directly to the energy production system, avoiding hydrogen storage and transportation. In this sense, research is oriented toward the optimization of the decentralized hydrogen production unit, generally named as fuel processor, for residential and automotive applications, for achieving fuel conversion into hydrogen with high efficiencies and high compactness.
Since the efficiency of the integrated fuel processor – fuel cell system strongly depends on system configuration and on the heat integration, a system analysis of the most promising configurations is performed, in order to identify the best solution for energy production in a PEM fuel cell system. Analysis of global system efficiency of fuel processor – PEM fuel cell systems is performed by means of the software AspenPlus®, with identification of best configuration and best operating conditions.
Moreover, since the application of fuel processor – PEM fuel cell system is foreseen for small and medium scale, an important characteristic that must me associated to the high efficiency is the compactness of the system. The PEM fuel cell, indeed, is generally characterized by high efficiency and compactness, therefore, in order to keep its standard, also the fuel processor coupled with it must be efficient and as compact as possible. In order to have an idea of the encumbrance of the reactors, a detailed mathematical model for fixed bed reactors was developed in this work, in order to size and compare conventional fixed bed reactor and membrane catalytic reactors. The software employed was Mathematica®.

description: We present results for the first observed outburst from the transient X-ray binary source MAXI J0637-430. This study is based on eight observations from the Nuclear Spectroscopic Telescope Array (NuSTAR) and six observations from the Neil Gehrels Swift Observatory X-Ray Telescope (Swift/XRT) collected from 2019 November 19 to 2020 April 26 as the 3-79 keV source flux declined from 8.2e-10 to 1.4e-12 erg/cm^2/s. We see the source transition from a soft state with a strong disk-blackbody component to a hard state dominated by a power-law or thermal Comptonization component. NuSTAR provides the first reported coverage of MAXI J0637-430 above 10 keV, and these broadband spectra show that a two-component model does not provide an adequate description of the soft state spectrum. As such, we test whether blackbody emission from the plunging region could explain the excess emission. As an alternative, we test a reflection model that includes a physical Comptonization continuum. Finally, we also test a spectral component based on reflection of a blackbody illumination spectrum, which can be interpreted as a simple approximation to the reflection produced by returning disk radiation due to the bending of light by the strong gravity of the black hole. We discuss the physical implications of each scenario and demonstrate the value of constraining the source distance.

The temperature dependencies of the Fermi level density of states and of the integrated density of states at low bias voltages show anomalies at T=6.5 K, the onset of multipolar ordering as detected by specific heat and other macroscopic measurements. In the ordered phase, we find a local density of states with a V-shape form, indicating a partial gap opening over the Fermi surface. The size of the gap according to the tunneling spectra is about 2 meV.

description: One contribution to any dark sector's abundance comes from its gravitational production during inflation. If the dark sector is weakly coupled to the inflaton and the Standard Model, this can be its only production mechanism. For non-interacting dark sectors, such as a free massive fermion or a free massive vector field, this mechanism has been studied extensively. In this paper we show, via the example of dark massive QED, that the presence of interactions can result in a vastly different mass for the dark matter (DM) particle, which may well coincide with the range probed by upcoming experiments. In the context of dark QED we study the evolution of the energy density in the dark sector after inflation. Inflation produces a cold vector condensate consisting of an enormous number of bosons, which via interesting processes - Schwinger pair production, strong field electromagnetic cascades, and plasma dynamics - transfers its energy to a small number of "dark electrons" and triggers thermalization of the dark sector. The resulting dark electron DM mass range is from 50 MeV to 30 TeV, far different from both the $10^{-5}$ eV mass of the massive photon dark matter in the absence of dark electrons, and from the $10^9$ GeV dark electron mass in the absence of dark photons. This can significantly impact the search strategies for dark QED and, more generally, theories with a self-interacting DM sector. In the presence of kinetic mixing, a dark electron in this mass range can be searched for with upcoming direct detection experiments, such as SENSEI-100g and OSCURA.

title: The challenge presented by dissociations and synaesthesia for the neo-dualism of David Chalmers and Tim Bayne
Creators: name: Fletcher, Robert
Publisher: name: University of Reading
Year: 2020

description: This thesis has, as its primary target, the neo-cartesianism, or property dualism of certain philosophers of mind: David Chalmers, Tim Bayne, and others. All begin with a pre-theoretic commitment to the view that all perceptual states are conscious. They define consciousness by saying that it is synonymous with having ‘qualia’ – a term directed at phenomenal properties which defy reduction to physical states. The thesis argues that this position is challenged by certain neurological conditions, - blindsight, visual form agnosia etc- which we can generalise as ‘dissociations’: conditions in which functions are separated from awareness. The thesis holds that these are examples of unconscious perception, which present the case for a different pre-theoretic position, and a redefinition of concepts used in the vicinity. Insofar as the neo-cartesians recognise the empirical, their inclination to reject the dissociations is challenged with new cases and paradigms which have emerged in recent years. It is contended that the dissociations disrupt Chalmers’ coherence between the phenomenal and the psychological, Bayne’s commitment to the Unity of Consciousness, and Phillips’ campaign against unconscious perception. In addition, synaesthesia is advanced as a problem case for Bayne’s unity contention. I argue that the dissociations are not easily dismissed, and present a real challenge for neo-cartesianism. In exploring this challenge, the thesis contributes to the case for a different philosophy of mind – a Higher Order Thought (HOT) approach. The notion of unconscious perception – it is contended - much more easily finds an accommodation in HOT theories, so this thesis contributes to existing arguments for that position. HOT theories also have an advantage in being receptive to reduction, in giving a developmental account of consciousness, and in being more open to the accommodation of empirical discoveries. In each respect, there is an advantage over the respective positions taken by Chalmers and Bayne.
The monitoring system of the ATLAS muon spectrometer read out driver
Creators: name: Capasso, Luciano
Publisher: name: Università degli Studi di Napoli Federico II
Year: 2010

description: My PhD work focuses upon the Read Out Driver (ROD) of the ATLAS Muon Spectrometer. The ROD is a VME64x board, designed around two Xilinx Virtex-II FPGAs and an ARM7 microcontroller and it is located off-detector, in a counting room of the ATLAS cavern at the CERN. The readout data of the ATLAS’ RPC Muon spectrometer are collected by the front-end electronics and transferred via optical fibres to the ROD boards in the counting room. The ROD arranges all the data fragments of a sector of the spectrometer in a unique event. This is made by the Event Builder Logic, a cluster of Finite State Machines that parses the fragments, checks their syntax and builds an event containing all the sector data. In the presentation I will describe the Builder Monitor, developed by me in order to analyze the Event Builder timing performance. It is designed around a 32-bit soft-core microprocessor, embedded in the same FPGA hosting the Builder logic. This approach makes it possible to track the algorithm execution in the field. The Monitor performs real time and statistical analysis of the state machine dynamics. The microprocessor is interfaced with custom peripherals which read out the state registers, fill histograms and transfer them via DMA to the processor memory. The Builder Monitor also measures the elapsed time for each event, its length and keeps track of the error status words.
In my thesis I will describe the hardware-software co-design of the Builder Monitor and the role played by the custom peripherals. I will also present experimental results and the procedure I developed to check out errors and to debug software.

description: Magnetic penetration depth, $λ_{m}$, was measured as a function of temperature and magnetic field in single crystals of low carrier density superconductor YPtBi by using a tunnel-diode oscillator technique. Measurements in zero DC magnetic field yield London penetration depth, $λ_{L}\left(T\right)$, but in the applied field the signal includes the Campbell penetration depth, $λ_{C}\left(T\right)$, which is the characteristic length of the attenuation of small excitation field, $H_{ac}$, into the Abrikosov vortex lattice due to its elasticity. Whereas the magnetic field dependent $λ_C$ exhibit $λ_{C}\sim B^{p}$ with $p=1/2$ in most of the conventional and unconventional superconductors, we found that $p\approx 0.23\ll1/2$ in YPtBi due to rapid suppression of the pinning strength. From the measured $λ_{C}(T,H)$, the critical current density is $j_{c}\approx40\,\mathrm{A}/\mathrm{cm^{2}}$ at 75 mK. This is orders of magnitude lower than that of conventional superconductors of comparable $T_{c}$. Since the pinning centers (lattice defects) and vortex structure are not expected to be much different in YPtBi, this observation is direct evidence of the low density of the Cooper pairs because $j_{c}\propto n_s$.

description: The notion of data depth has long been in use to obtain robust location and scale estimates in a multivariate setting. The depth of an observation is a measure of its centrality, with respect to a data set or a distribution. The data depths of a set of multivariate observations translates to a center-outward ordering of the data. Thus, data depth provides a generalization of the median to a multivariate setting (the deepest observation), and can also be used to screen for extreme observations or outliers (the observations with low data depth). Data depth has been used in the development of a wide range of robust and non-parametric methods for multivariate data, such as non-parametric tests of location and scale [Li and Liu (2004)], multivariate rank-tests [Liu and Singh (1993)], non-parametric classification and clustering [Jornsten (2004)], and robust regression [Rousseeuw and Hubert (1999)]. Many different notions of data depth have been developed for multivariate data. In contrast, data depth measures for functional data have only recently been proposed [Fraiman and Muniz (1999), López-Pintado and Romo (2006a)]. While the definitions of both of these data depth measures are motivated by the functional aspect of the data, the measures themselves are in fact invariant with respect to permutations of the domain (i.e. the compact interval on which the functions are defined). Thus, these measures are equally applicable to multivariate data where there is no explicit ordering of the data dimensions. In this paper we explore some extensions of functional data depths, so as to take the ordering of the data dimensions into account.

The development and application of a one-level mesoscale atmospheric model over the Lower Fraser Valley of British Columbia
Creators: name: Ayotte, Keith Willard
Publisher: name: University of British Columbia
Year: 2010

description: This study involves the use of a one-level mesoscale numerical model to simulate thermally driven, topographically chanelled atmospheric flow over the Lower Fraser Valley of British Columbia. The model used is a modified version of a model developed by Mass Dempsey at the University of Washington. The model was modified to include friction parameterization that was spatially variable and stability dependent. The diabatic surface heating parameterization was also modified to account for spatial variability of surface thermal characteristics. Model runs of July 20,1985 and August 23,1985 are presented in this study. The model is validated using data from a measurement network over the model domain. Statistics of the validation on the two days modeled are presented. It was found that the modified model is quite sensitive to the surface thermal characteristics specified but relatively insensitive to spatial variability of surface roughness. The model is limited in its ability to resolve effects of small topographic features in high Froude number situations but the large scale flow around topographic features is well modeled. Synoptic scale thermally induced pressure gradients are found to affect ability of the model to simulate near surface flow within the domain. It is suggested that the model be nested in a lower resolution grid in order to account for this forcing. It was concluded that this modification, coupled with more accurate specification of the surface characteristics over the model domain would enhance the agreement between modeled and observed fields.

description: For many data mining and machine learning tasks, the quality of a similarity measure is the key for their performance. To automatically find a good similarity measure from datasets, metric learning and similarity learning are proposed and studied extensively. Metric learning will learn a Mahalanobis distance based on positive semi-definite (PSD) matrix, to measure the distances between objectives, while similarity learning aims to directly learn a similarity function without PSD constraint so that it is more attractive. Most of the existing similarity learning algorithms are online similarity learning method, since online learning is more scalable than offline learning. However, most existing online similarity learning algorithms learn a full matrix with d 2 parameters, where d is the dimension of the instances. This is clearly inefficient for high dimensional tasks due to its high memory and computational complexity. To solve this issue, we introduce several Sparse Online Relative Similarity (SORS) learning algorithms, which learn a sparse model during the learning process, so that the memory and computational cost can be significantly reduced. We theoretically analyze the proposed algorithms, and evaluate them on some real-world high dimensional datasets. Encouraging empirical results demonstrate the advantages of our approach in terms of efficiency and efficacy.
8th-Century Mayen Ware Pitcher Found in Ribe (Syddanmark / DK)

description: A completely intact pitcher was found during excavations in the pre-Christian cemetery of the early medieval emporium of Ribe in 2015. Through typological comparisons, the pitcher was identified as a Kleeblattkanne (trefoil-mouthed jug), probably manufactured in Mayen or its region in the 8th century. Further analysis of the pitcher’s contents revealed that it had been used as an urn for the deposition of the cremated remains of a small child, probably less than two years old. The remains were accompanied by glass beads, as well as the fragments of a comb and comb case. Radiocarbon dating of the contents supports the typological dating provided by the artefacts and the pitcher to the 8th century. Cremation deposits in urns are attested by other examples in Ribe’s pre-Christian cemetery, although cremated deposits in pits and inhumations in the form of simple earth graves are more common. These burial practices bear strong similarities to those documented along the Eastern and Northern Frisian coast. The pitcher itself is so far unique in Scandinavia. Mayen ware more generally is relatively rare in a North Sea context in comparison to later pottery products from the Cologne Bay, such as Badorf and Pingsdorf wares. However, it is distinctly present in early emporia and counts among the earliest examples of the pottery trade from this region. The trading connections between Ribe and the Cologne Bay are further attested by a range of imported goods, including Badorf ware pottery, glass vessels, and quern stones made of Niedermendig basalt. Together with the pitcher found in the cemetery, these finds attest to the trading links and cultural exchanges between Ribe, Frisia and the Middle Rhine area in the 8th century.

description: Multiferroics offer an elegant means to implement voltage-control and on the fly reconfigurability in microscopic, nanoscaled systems based on ferromagnetic materials. These properties are particularly interesting for the field of magnonics, where spin waves are used to perform advanced logical or analogue functions. Recently, the emergence of nano-magnonics {\color{black} is expected to} eventually lead to the large-scale integration of magnonic devices. However, a compact voltage-controlled, on demand reconfigurable magnonic system has yet to be shown. Here, we introduce the combination of multiferroics with ferromagnets in a fully epitaxial heterostructure to achieve such voltage-controlled and reconfigurable magnonic systems. Imprinting a remnant electrical polarization in thin multiferroic $\mathrm{BiFeO_3}$ with a periodicity of $500\,\mathrm{nm}$ yields a modulation of the effective magnetic field in the micron-scale, ferromagnetic $\mathrm{La_{2/3}Sr_{1/3}MnO_3}$ magnonic waveguide. We evidence the magneto-electrical coupling by characterizing the spin wave propagation spectrum in this artificial, voltage induced, magnonic crystal and demonstrate the occurrence of a robust magnonic bandgap with $>20 \,\mathrm{dB}$ rejection.
Grasp and manipulation of objects with a multi-fingered hand in unstructured environments

description: In this thesis, new methods to grasp and to manipulate unknown objects with a robotic multi-fingered hand have been proposed.
These methods have the goals to reduce the time of the execution of the grasp to be suitable with real-time applications and to exploit the redundancy in the ``multi-fingered hand + object"  system in order to optimize other subtasks during manipulation.
In particular, a visual system has been used to cope with the problem of unknown objects grasping.
Then, it is straightforward to recognize that two main tasks have to be performed in such a context: object recognition/reconstruction and grasp planning.
The motivation behind the proposed algorithm is that the visual reconstruction algorithm should guide the object's grasp planner in a coordinated manner.
The same coordination aspects are the key-points of the proposed method about manipulation of objects: now, the fingers of the robotic hand have to cooperate in order to manipulate the object in the desired way with a good dexterity and this can be done exploiting the redundancy of the whole system.

description: The territory of former Eastern Poland formed part of the wider ethno-cultural frontier developed between Polish Mazovia and Turovian Rus’ and Volhynia between the second half of the 10th and the second half of the 13th century. Overall, its mosaic-like cultural landscape was formed by the traditional, pagan background and Christian influences reflecting direct contact between the Catholic and Orthodox Churches as the political border started to take shape, probably in the first half of the 11th century. The main markers of the cultural change related to the religious conversion are inhumation graves, appearing as barrows, cemeteries with stone-kerbed graves and the flat graveyards of rural populations and proto-urban societies. Individuals chosen from all of these were archaeo-genetically examined. Genetic analyses show, for example, that the people who built the stone-kerbed graves in the Drohiczyn Upland, from the second half of the 11th century forming the most western part of the Rus’ territory, were different from their neighbours settling other parts of the region in the same period. This observation corresponds with studies of the development of settlement, spatially and chronologically, which show that a »rapid« growth of settlement in this area could be due to a planned colonization after a state territorial annexation in the second quarter of the 11th century. The existence of a genetic continuity between the medieval population of the Polish-Ruthenian frontier and modern populations from Central, Northern and Eastern Europe must also be considered. Thus, genetic analyses can define new fields of research and provide new arguments for ethno-cultural interpretations.

description: Switching voltage of first-order metal-insulator transition (MIT) in VO_2, an inhomogeneous strongly correlated system, is changed by irradiating an infrared light with wavelength, 1.5 micrometer, and applying the electric field (photo-induced switching). This was predicted in the hole-driven MIT theory in which hole doping of a low concentration below 0.01% into conduction band (Fermi surface) induces the abrupt MIT as correlation effect. The switching is explained by the Mott transition not the Peierls transition.

Von ursprünglich 26 als deformiert geltenden Schädeln wurden 14 als nicht-deformiert oder intermediär angesprochen, darunter auch drei Schädel aus dem Gräberfeld von Altheim. In einem Artikel versuchen nun Grupe u. a. (2018) eigene Belege zu erbringen, um eine künstliche Deformation der Altheimer Schädel zu beweisen, gleichzeitig üben sie Kritik 578 B. Trautmann u. a. · Zur Problematik der Bestimmung artifiziell deformierter Schädel aus Altheim an der Vorgehensweise in Trautmann u. a. (2017). Sie versuchen dabei mithilfe von Röntgen- und CT-Aufnahmen sogenannte Hirndrucksymptome zu diagnostizieren, anhand derer sich angeblich künstliche Schädeldeformationen ableiten lassen sollen. Im vorliegenden Artikel gehen die Autoren auf die Kritik von Grupe u. a. (2018) an den in Trautmann u. a. (2017) genutzten Methoden ein und evaluieren ihrerseits die von Grupe u. a.

About the People Buried in the Cemetery of Baitai: their Cultural Integration throughout the Baltic Sea Region and the European Barbaricum in the 3rd Century AD

description: The aim of this article is to present several types of jewellery dating to around the time of Phase C2 from the Baitai Cemetery in Western Lithuania. These examples have been chosen to detect their role as indicators of far-flung contacts with Germanic areas in the Baltic Sea region of the European Barbaricum. The Western Balts dwelling on what nowadays is the Lithuanian coastland during the Late Roman Period were connected culturally not only with neighbouring kin-tribes, especially those living in Samland and Masuria, but also kept vital contacts with Germanic peoples in the Baltic Sea region. The Germanic fashion favoured by the Baitai elite is testified by a small silver-gilt detail on a rosette brooch of Group 6 according to the typology of Przybyła found in Grave 31. The origin of the production of Group 6 brooches is associated mainly with the Wielbark culture (Poland) and the region of Frisches Haff. The findings of these brooches on Bornholm, Gotland and in Västergötland indicate that for the Germanic people of the Wielbark culture and for the Western Balts inhabiting the coast the closest ties via the Baltic Sea were towards the north-northwest. The silver spiral ring with broadened terminals found in the same Baitai Grave 31 represents locally made jewellery, created following the examples of Scandinavian snakehead rings (Schlangenkopffingerringe). Another spiral finger ring from Baitai Grave 22 was made partly of twisted and partly of notched silver wire, close to the style of ornaments produced for the elite in various regions of the European Barbaricum. The type of round tutuli pins from Baitai Grave 8 is a local creation of the Late Roman Period and based on several sources of inspiration. One of these is a rosette tutulus seen in brooches in areas along the River Elbe and in Southern Scandinavia. It is noticeable that in the same horizon of the later version of tutulus of Phase C2 bronze bracelets with slightly thickened terminals (early versions of club-headed arm rings [Kolbenarmringe]) appeared in the Western Lithuanian areas. Most probably, they are modest parallels to the fashion of luxury gold and silver Kolbenarmringe known in various regions of the Germania Libera. Intensive, far-flung contacts of the inhabitants of what is now the Lithuanian coastland via the Baltic Sea brought new »cosmopolitan trends« of costume which merged into the local fashion of the Western Balts during the 3rd century. The Baitai cemetery finds are one of the important sources for intensive communication between the Germanic and Balt people.

On kappa-deformation and triangular quasibialgebra structure

description: We show that, up to terms of order 1/kappa^5, the kappa-deformed Poincare algebra can be endowed with a triangular quasibialgebra structure. The universal R matrix and coassociator are given explicitly to the first few orders. In the context of kappa-deformed quantum field theory, we argue that this structure, assuming it exists to all orders, ensures that states of any number of identical particles, in any representation, can be defined in a kappa-covariant fashion.

description: Grabungen auf dem »Blöskopf« bei Bad Ems an der Lahn erbrachten eine römische Militäranlage von ca. 0,1 ha Größe aus claudisch-neronischer Zeit. Im inneren Spitzgraben wurden erstmals angespitzte Hölzer in Form eines Annäherungshindernisses in situ und in exzellenter Erhaltung nachgewiesen. Sie werden analog zu den pila muralia mit dem nicht überlieferten Begriff »pila fossata« bezeichnet. Die militärische Anlage war in ein lineares Wall-Graben-System eingebunden und erfüllte vermutlich die Aufgabe einer Geländesperre. Ein dahinter liegendes Pingenfeld sowie Schlackenfunde aus römischen Befundkontexten legen einen Zusammenhang mit Bergbauaktivitäten nahe. Der Nachweis einer römischen Zeitstellung dieser Pingen steht noch aus.

description: Reservoir computers are powerful tools for chaotic time series prediction. They can be trained to approximate phase space flows and can thus both predict future values to a high accuracy, as well as reconstruct the general properties of a chaotic attractor without requiring a model. In this work, we show that the ability to learn the dynamics of a complex system can be extended to systems with co-existing attractors, here a 4-dimensional extension of the well-known Lorenz chaotic system. We demonstrate that a reservoir computer can infer entirely unexplored parts of the phase space: a properly trained reservoir computer can predict the existence of attractors that were never approached during training and therefore are labelled as unseen. We provide examples where attractor inference is achieved after training solely on a single noisy trajectory.
