description: In this lecture we discuss some interesting developments in the modern theory of electromagnetic field(s). In particular, by using the methods developed in Dirac's constraint dynamics we derive the Schrödinger equation for the free electromagnetic field. The electromagnetic field that arises only contains combinations of transverse photons and does not include any scalar and/or longitudinal photons. This approach is also used to determine and investigate the actual symmetry of the free electromagnetic field. Then we discuss the Majorana representation of the Maxwell equations, the symmetric form of Maxwell equations and an original approach to electrodynamics called the "scalar electrodynamics".

description: Determining phenotype from genetic data is a fundamental challenge. Influenza A viruses undergo rapid antigenic drift and identification of emerging antigenic variants is critical to the vaccine selection process. Using former seasonal influenza A(H1N1) viruses, hemagglutinin sequence and corresponding antigenic data were analyzed in combination with 3-D structural information. We attributed variation in hemagglutination inhibition to individual amino acid substitutions and quantified their antigenic impact, validating a subset experimentally using reverse genetics. Substitutions identified as low-impact were shown to be a critical component of influenza antigenic evolution and by including these, as well as the high-impact substitutions often focused on, the accuracy of predicting antigenic phenotypes of emerging viruses from genotype was doubled. The ability to quantify the phenotypic impact of specific amino acid substitutions should help refine techniques that predict the fitness and evolutionary success of variant viruses, leading to stronger theoretical foundations for selection of candidate vaccine viruses.

description: The Smoothing Spline ANOVA (SS-ANOVA) requires a specialized construction of basis and penalty terms in order to incorporate prior knowledge about the data to be fitted. Typically, one resorts to the most general approach using tensor product splines. This implies severe constraints on the correlation structure, i.e. the assumption of isotropy of smoothness can not be incorporated in general. This may increase the variance of the spline fit, especially if only a relatively small set of observations are given. In this article, we propose an alternative method that allows to incorporate prior knowledge without the need to construct specialized bases and penalties, allowing the researcher to choose the spline basis and penalty according to the prior knowledge of the observations rather than choosing them according to the analysis to be done. The two approaches are compared with an artificial example and with analyses of fixation durations during reading.

description: The present work couples the phase field method of fracture to the Armstrong-Frederick model of plasticity with the kinematic hardening. The chosen approach inherits the advantages of both techniques and is aimed at the study of low cycle fatigue effects in ductile materials. However, the numerical implementation of this promising concept brings with it several challenges, such as the definition of a unique framework for both setups, the derivation of coupled evolution equations, the distinction between tension and compression mode and the development of a computationally efficient algorithm. In the approach developed, the derivation of evolution equations uses the minimum principle of the dissipation potential. This step requires the expression of the dissipation potential of the classic Armstrong-Frederick model in terms of the internal variable rates by using the Legendre transformation. The model is eventually implemented in the FE-program and applied in order to investigate the life-time of the cold-formed carbon steel and the cold-formed stainless steel.

description: Most climate change impacts manifest in the form of natural hazards. Damage assessment typically relies on damage functions that translate the magnitude of extreme events to a quantifiable damage. In practice, the availability of damage functions is limited due to a lack of data sources and a lack of understanding of damage processes. The study of the characteristics of damage functions for different hazards could strengthen the theoretical foundation of damage functions and support their development and validation. Accordingly, we investigate analogies of damage functions for coastal flooding and for wind storms and identify a unified approach. This approach has general applicability for granular portfolios and may also be applied, for example, to heat-related mortality. Moreover, the unification enables the transfer of methodology between hazards and a consistent treatment of uncertainty. This is demonstrated by a sensitivity analysis on the basis of two simple case studies (for coastal flood and storm damage). The analysis reveals the relevance of the various uncertainty sources at varying hazard magnitude and on both the microscale and the macroscale level. Main findings are the dominance of uncertainty from the hazard magnitude and the persistent behaviour of intrinsic uncertainties on both scale levels. Our results shed light on the general role of uncertainties and provide useful insight for the application of the unified approach.

description: Quantum key distribution (QKD) allows secret key exchange between two users with unconditional security. For QKD to be widely deployed, low cost and compactness are crucial requirements alongside high performance. Currently, the majority of QKD systems demonstrated rely on bulk intensity and phase modulators to generate optical pulses with precisely defined amplitude and relative phase difference i.e., to encode information as signal states and decoy states. However, these modulators are expensive and bulky, thereby limiting the compactness of QKD systems. Here, we present and experimentally demonstrate a novel optical transmitter design to overcome this disadvantage by generating intensity- and phase-tunable pulses at GHz clock speeds. Our design removes the need for bulk modulators by employing directly modulated lasers in combination with optical injection locking and coherent interference. This scheme is, therefore, well suited to miniaturization and photonic integration, and we implement a proof-of-principle QKD demonstration to highlight potential applications.

description: Fluxes of organic and inorganic carbon within the Amazon basin are considerably controlled by annual flooding, which triggers the export of terrigenous organic material to the river and ultimately to the Atlantic Ocean. The amount of carbon imported to the river and the further conversion, transport and export of it depend on temperature, atmospheric CO2, terrestrial productivity and carbon storage, as well as discharge. Both terrestrial productivity and discharge are influenced by climate and land use change. The coupled LPJmL and RivCM model system (Langerwisch et al., 2016) has been applied to assess the combined impacts of climate and land use change on the Amazon riverine carbon dynamics. Vegetation dynamics (in LPJmL) as well as export and conversion of terrigenous carbon to and within the river (RivCM) are included. The model system has been applied for the years 1901 to 2099 under two deforestation scenarios and with climate forcing of three SRES emission scenarios, each for five climate models. We find that high deforestation (business-as-usual scenario) will strongly decrease (locally by up to 90 %) riverine particulate and dissolved organic carbon amount until the end of the current century. At the same time, increase in discharge leaves net carbon transport during the first decades of the century roughly unchanged only if a sufficient area is still forested. After 2050 the amount of transported carbon will decrease drastically. In contrast to that, increased temperature and atmospheric CO2 concentration determine the amount of riverine inorganic carbon stored in the Amazon basin. Higher atmospheric CO2 concentrations increase riverine inorganic carbon amount by up to 20% (SRES A2). The changes in riverine carbon fluxes have direct effects on carbon export, either to the atmosphere via outgassing or to the Atlantic Ocean via discharge. The outgassed carbon will increase slightly in the Amazon basin, but can be regionally reduced by up to 60% due to deforestation. The discharge of organic carbon to the ocean will be reduced by about 40% under the most severe deforestation and climate change scenario. These changes would have local and regional consequences on the carbon balance and habitat characteristics in the Amazon basin itself as well as in the adjacent Atlantic Ocean.

Intrusion Detection System based on time related features and Machine Learning
Creators: name: FAUSTO, ALESSANDRO
Publisher: name: Universit� degli studi di Genova
Year: 2022

description: The analysis of the behavior of network communications over time allows the extraction of statistical features capable of characterizing the network traffic flows. These features can be used to create an Intrusion Detection System (IDS) that can automatically classify network traffic. But introducing an IDS into a network changes the latency of its communications. From a different viewpoint it is possible to analyze the latencies of a network to try to identifying the presence or absence of the IDS. The proposed method can be used to extract a set of phisical or time related features that characterize the communication behavior of an Internet of Things (IoT) infrastructure. For example the number of packets sent every 5 minutes. Then these features can help identify anomalies or cyber attacks. For example a jamming of the radio channel. This method does not necessarily take into account the content of the network packet and therefore can also be used on encrypted connections where is impossible to carry out a Deep Packet Inspection (DPI) analysis.

description: Antibodies against spike proteins of influenza are used as a tool for characterization of viruses and therapeutic approaches. However, development, production and quality control of antibodies is expensive and time consuming. To circumvent these difficulties, three peptides were derived from complementarity determining regions of an antibody heavy chain against influenza A spike glycoprotein. Their binding properties were studied experimentally, and by molecular dynamics simulations. Two peptide candidates showed binding to influenza A/Aichi/2/68 H3N2. One of them, termed PeB, with the highest affinity prevented binding to and infection of target cells in the micromolar region without any cytotoxic effect. PeB matches best the conserved receptor binding site of hemagglutinin. PeB bound also to other medical relevant influenza strains, such as human-pathogenic A/California/7/2009 H1N1, and avian-pathogenic A/MuteSwan/Rostock/R901/2006 H7N1. Strategies to improve the affinity and to adapt specificity are discussed and exemplified by a double amino acid substituted peptide, obtained by substitutional analysis. The peptides and their derivatives are of great potential for drug development as well as biosensing.

description: In the last years, the phase field method has established itself for the simulation of various problem types, especially in the fields of microstructure evolution and phase transformations as well as in fluid dynamics. Concerning the first two cases, usually a constant, deformation-independent, surface energy is considered. In this work, however, deformation-dependent surface elasticity according to [5] will be incorporated into phase field theory. In line with [4], a finite element framework for an Allen-Cahn type phase field model coupled to continuum mechanics is presented, which is solved in a monolithic manner by means of Newton's method. The resulting model also accounts for a spatial evolution of the diffuse interface by a functional of Ginzburg–Landau type. The implemented model is employed in numerical simulations. These will be used to study the behavior of the phase field model.

description: We used the Laguerre polynomials method for determination of the proton structure function in the valon model. We have examined the applicability of the valon model with respect to a very elegant method, where the structure of the proton is determined by expanding valon distributions and valon structure functions on Laguerre polynomials. We compared our results with the experimental data, GJR parameterization and DL model. Having checked, this method gives a good description for the proton structure function in valon model.

description: In this monograph, we extend S. Schwede's exact sequence interpretation of the Gerstenhaber bracket in Hochschild cohomology to certain exact and monoidal categories. Therefore we establish an explicit description of an isomorphism by A. Neeman and V. Retakh, which links $\mathrm{Ext}$-groups with fundamental groups of categories of extensions and relies on expressing the fundamental group of a (small) category by means of the associated Quillen groupoid. As a main result, we show that our construction behaves well with respect to structure preserving functors between exact monoidal categories. We use our main result to conclude, that both the Lie bracket and the squaring map in Hochschild cohomology are invariants under Morita equivalence. For quasi-triangular bialgebras, we further determine a significant part of the Lie bracket's kernel, and thereby prove a conjecture by L. Menichi. Along the way, we introduce $n$-extension closed and entirely extension closed subcategories of abelian categories, and study some of their properties.

description: Exosomes are small membrane vesicles released by different cell types, including hepatocytes, that play important roles in intercellular communication. We have previously demonstrated that hepatocyte-derived exosomes contain the synthetic machinery to form sphingosine-1-phosphate (S1P) in target hepatocytes resulting in proliferation and liver regeneration after ischemia/reperfusion (I/R) injury. We also demonstrated that the chemokine receptors, CXCR1 and CXCR2, regulate liver recovery and regeneration after I/R injury. In the current study, we sought to determine if the regulatory effects of CXCR1 and CXCR2 on liver recovery and regeneration might occur via altered release of hepatocyte exosomes. We found that hepatocyte release of exosomes was dependent upon CXCR1 and CXCR2. CXCR1-deficient hepatocytes produced fewer exosomes, whereas CXCR2-deficient hepatocytes produced more exosomes compared to their wild-type controls. In CXCR2-deficient hepatocytes, there was increased activity of neutral sphingomyelinase (Nsm) and intracellular ceramide. CXCR1-deficient hepatocytes had no alterations in Nsm activity or ceramide production. Interestingly, exosomes from CXCR1-deficient hepatocytes had no effect on hepatocyte proliferation, due to a lack of neutral ceramidase and sphingosine kinase. The data demonstrate that CXCR1 and CXCR2 regulate hepatocyte exosome release. The mechanism utilized by CXCR1 remains elusive, but CXCR2 appears to modulate Nsm activity and resultant production of ceramide to control exosome release. CXCR1 is required for packaging of enzymes into exosomes that mediate their hepatocyte proliferative effect.

description: The extent of gene flow during the range expansion of non-native species influences the amount of genetic diversity retained in expanding populations. Here, we analyse the population genetic structure of the raccoon dog (Nyctereutes procyonoides) in north-eastern and central Europe. This invasive species is of management concern because it is highly susceptible to fox rabies and an important secondary host of the virus. We hypothesized that the large number of introduced animals and the species' dispersal capabilities led to high population connectivity and maintenance of genetic diversity throughout the invaded range. We genotyped 332 tissue samples from seven European countries using 16 microsatellite loci. Different algorithms identified three genetic clusters corresponding to Finland, Denmark and a large 'central' population that reached from introduction areas in western Russia to northern Germany. Cluster assignments provided evidence of long-distance dispersal. The results of an Approximate Bayesian Computation analysis supported a scenario of equal effective population sizes among different pre-defined populations in the large central cluster. Our results are in line with strong gene flow and secondary admixture between neighbouring demes leading to reduced genetic structuring, probably a result of its fairly rapid population expansion after introduction. The results presented here are remarkable in the sense that we identified a homogenous genetic cluster inhabiting an area stretching over more than 1500km. They are also relevant for disease management, as in the event of a significant rabies outbreak, there is a great risk of a rapid virus spread among raccoon dog populations.

description: The aim of the present study was to test the functional relevance of the spatial concepts UP or DOWN for words that use these concepts either literally (space) or metaphorically (time, valence). A functional relevance would imply a symmetrical relationship between the spatial concepts and words related to these concepts, showing that processing words activate the related spatial concepts on one hand, but also that an activation of the concepts will ease the retrieval of a related word on the other. For the latter, the rotation angle of participant's body position was manipulated either to an upright or a head-down tilted body position to activate the related spatial concept. Afterwards participants produced in a within-subject design previously memorized words of the concepts space, time and valence according to the pace of a metronome. All words were related either to the spatial concept UP or DOWN. The results including Bayesian analyses show (1) a significant interaction between body position and words using the concepts UP and DOWN literally, (2) a marginal significant interaction between body position and temporal words and (3) no effect between body position and valence words. However, post-hoc analyses suggest no difference between experiments. Thus, the authors concluded that integrating sensorimotor experiences is indeed of functional relevance for all three concepts of space, time and valence. However, the strength of this functional relevance depends on how close words are linked to mental concepts representing vertical space.

description: The present study examines the effect of language experience on vocal emotion perception in a second language. Native speakers of French with varying levels of self-reported English ability were asked to identify emotions from vocal expressions produced by American actors in a forced-choice task, and to rate their pleasantness, power, alertness and intensity on continuous scales. Stimuli included emotionally expressive English speech (emotional prosody) and non-linguistic vocalizations (affect bursts), and a baseline condition with Swiss-French pseudo-speech. Results revealed effects of English ability on the recognition of emotions in English speech but not in non-linguistic vocalizations. Specifically, higher English ability was associated with less accurate identification of positive emotions, but not with the interpretation of negative emotions. Moreover, higher English ability was associated with lower ratings of pleasantness and power, again only for emotional prosody. This suggests that second language skills may sometimes interfere with emotion recognition from speech prosody, particularly for positive emotions.

description: Processes involved in late bilinguals' production of morphologically complex words were studied using an event-related brain potentials (ERP) paradigm in which EEGs were recorded during participants' silent productions of English past- and present-tense forms. Twenty-three advanced second language speakers of English (first language [L1] German) were compared to a control group of 19 L1 English speakers from an earlier study. We found a frontocentral negativity for regular relative to irregular past-tense forms (e.g., asked vs. held) during (silent) production, and no difference for the present-tense condition (e.g., asks vs. holds), replicating the ERP effect obtained for the L1 group. This ERP effect suggests that combinatorial processing is involved in producing regular past-tense forms, in both late bilinguals and L1 speakers. We also suggest that this paradigm is a useful tool for future studies of online language production.

description: Placement tests are utilized in community colleges to assess students’ academic readiness in reading, writing, and math. Scores on these tests often determine whether students are placed directly into college-level courses or are required to take remedial classes. Previous research has shown that student outcomes in remediation are poor, and remedial coursework can cost additional funds and extend students’ educational timelines. Studies have also shown that students of color and those from lower socioeconomic backgrounds are more frequently assigned to remediation, and many students are misplaced into remedial coursework when they could have been successful in college-level work. Therefore, it is critical that placement tests are examined for accuracy and equity. A Large Midwestern Community College System recently adopted a new placement test called EdReady English to assess students’ readiness in reading and writing. This quantitative study analyzed the accuracy of the EdReady English placement test at a selected campus of a Large Midwestern Community College System to determine how students who were placed by EdReady English performed in their first credit-bearing English course. Additionally, student subgroups were analyzed to determine if students’ grades in the first credit-bearing English course varied by demographic factors such as age, race, and gender. Finally, the grades of students in the first credit-bearing English course were examined by placement method to determine how students who were placed by EdReady English performed compared to students who used other placement methods. The results of this study may be used to help policymakers and advisors determine the accuracy and equity of EdReady English as a placement tool.

description: The aim of this note is to compare the averaged optimal coplanar transfer towards circular orbits when the costs are the transfer time transfer and the energy consumption. While the energy case leads to analyze a 2D Riemannian metric using the standard tools of Riemannian geometry (curvature computations, geodesic convexity), the time minimal case is associated to a Finsler metric which is not smooth. Nevertheless a qualitative analysis of the geodesic flow is given in this article to describe the optimal transfers. In particular we prove geodesic convexity of the elliptic domain.

description: Electromyography (EMG) has been explored as an HCI input modality following a long history of success for prosthesis control. While EMG has the potential to address a range of hands-free interaction needs, it has yet to be widely accepted outside of prosthetics due to a perceived lack of robustness and intuitiveness. To understand how EMG input systems can be better designed, we sampled the ACM digital library to identify limitations in the approaches taken. Leveraging these works in combination with our research group's extensive interdisciplinary experience in this field, four themes emerged (1) interaction design, (2) model design, (3) system evaluation, and (4) reproducibility. Using these themes, we provide a step-by-step framework for designing EMG-based input systems to strengthen the foundation on which EMG-based interactions are built. Additionally, we provide a call-to-action for researchers to unlock the hidden potential of EMG as a widely applicable and highly usable input modality.

description: Specific Learning Disorders (SLD) represent a complex phenomenon that manifests itself in rather peculiar and typical areas. Generally, this type of problem requires the use of a series of elements and tools that allow the subject to acquire notions, skills and abilities. DSAs are mainly recognized due to their difficulty in automating learning practices, however, in parallel, there are consequences that are also reflected in the psychological and social sphere. In fact, it is found that this type of disorder is associated with emotional and relational problems. In this sense, sport can cover various and important functions for people with Specific Learning Disorders since, given its characteristics, it can represent a valid support tool. Physical activity and sport are in fact a valuable resource of behavioral, psychological, emotional and relational support.
The deployment of blockchain technology in the logistics and shipping industry: possible outcomes and need of uniform regulation
Creators: name: BERGAMINO, ANDREA

description: The aim of the thesis is to explore how the spread of blockchain technology can affect our society and the relevant legal relationships among individuals in the logistics and shipping industry, i.e. one of the sectors of economy which is making the greatest efforts to embrace such a ?revolution?. As it will be argued in the paper, the result probably lies somewhere in between a 'regulatory presence' and a 'cyber-anarchist' approach. For the law, it means that one should not use the full enforcement arsenal in all circumstances and the legal constraints should be adapted to technology (e.g. by creating legal comfort zones with regulatory sandboxes and safe harbours aimed at studying the impact of blockchain on some specific industries); for technology, it implies that it must be law-oriented. In this vein, the crucial and barycentric importance of tailoring a new role for the ?ordinary? law in its interaction with the so-called 'lex cryptographica' shall be duly explored and stressed in order to create a proper ?law of blockchain? which may (i) bridge the gap between the technology and the real landscape in which it would be supposed to operate; (ii) enable distributed ledgers to find a proper and functional use and, therefore, (iii) allow for trust in the blockchain not only by single ?nodes? in the online world but, rather, by all the people living in the real, ?physical?, world. Achieving such a goal is paramount if we wish to prevent all the evocative promises of a ?blockchain revolution? on real life from boiling down to what William Shakespeare defined as ?Much ado about nothing?. In this vein, the research project has been carried out with a multidisciplinary approach, which nevertheless allows to sketch some conclusion de iure condendo on the issues indicated above with reference to logistics and shipping industry, which undoubtedly constitutes a useful and interesting role model, principally due (i) to need by the maritime industry to find innovative ways of remaining competitive in a fast-changing world (especially after the recent and disruptive outbreak of Covid-19 pandemic ) while still addressing such longstanding concerns as intensive paperwork, tedious processes and data transparency; (ii) to the potential that blockchain technology hold in addressing industry concerns regarding trust among operators, data integrity, traceability, timeliness ad transparency; (iii) to several underlying analogies that such a distributed ledger shares with the ancestors of the documents that still govern maritime shipments and any related contractual relationships.

description: An irrational toric variety X is an analytic subset of the simplex associated to a finite configuration of real vectors. The positive torus acts on X by translation, and we consider limits of sequences of these translations. Our main result identifies all possible Hausdorff limits of translations of X as toric degenerations using elementary methods and the geometry of the secondary fan of the vector configuration. This generalizes work of Garcia-Puente et al., who used algebraic geometry and work of Kapranov, Sturmfels, and Zelevinsky, when the vectors were integral.

title: Design of an Original Methodology for the Efficient and Economic Appraisal of Existing and New Technologies in Form Grinding Processes including Helical
Creators: name: Hart, P
Publisher: name: Liverpool John Moores University
Year: 2019

description: The purpose of this research was to create and design a methodology for new product evaluation with an interest in the affects that they could have on form and helical grinding. The design uses a relatively small and commonly available grinding machine so that testing could be done without need for an expensive helical grinding machine typical of that utilised in industry. The contact conditions of the helical grinding process were considered, and the workpiece geometry was designed to closely replicate the form and entry and exit conditions found in helical form grinding of screw compressor rotors. The equipment design allows the grinding forces to be measured in axial, normal and tangential planes. This will allow the variation in axial forces to be explored and allow any variation in hydrodynamic forces to be investigated during the entry and exit regions. Grinding trials showed the importance of the need to measure the true depth of cut for a grinding pass. A novel method of measuring the depth of cut was designed that will allow an accurate measurement of the form position before and after a grinding pass. Replication methods for the workpiece and grinding wheel form were designed to allow capture on the grinding machine to facilitate an economic appraisal method that allows testing to be carried out in a short period of time. A 3D printed coolant nozzle was designed with an air scraper to overcome the air barrier around the periphery of the grinding. The aim of the design was to reduce the need for a high pressure grinding fluid jet and allowing less turbulent flow to enter the grinding nip at lower pressures. A preliminary cost model was created with inputs that relate to form grinding and allow the user to investigate different process parameters and arrive at a cost per part.

description: Highly accurate and predictive models of resistive switching devices are needed to enable future memory and logic design. Widely used is the memristive modeling approach considering resistive switches as dynamical systems. Here we introduce three evaluation criteria for memristor models, checking for plausibility of the I-V characteristics, the presence of a sufficiently non-linearity of the switching kinetics, and the feasibility of predicting the behavior of two anti-serially connected devices correctly. We analyzed two classes of models: the first class comprises common linear memristor models and the second class widely used non-linear memristive models. The linear memristor models are based on Strukovs initial memristor model extended by different window functions, while the non-linear models include Picketts physics-based memristor model and models derived thereof. This study reveals lacking predictivity of the first class of models, independent of the applied window function. Only the physics-based model is able to fulfill most of the basic evaluation criteria.
