description: This work was conducted in order to establish the behavior of Ir@Pt core@shell nanoparticles (NPs) during the catalysis of the ethanol oxidation reaction (EOR). Ir@Pt catalysts with < 1 monolayer of the Pt shell were synthesized using the well-established polyol method, which involves the use of a capping ligand. The NPs were tested for the EOR at both room and elevated (70 ̊C) temperatures, as well as acetaldehyde oxidation at room temperature. Ir was found to be more active towards the EOR at lower potentials and Pt at higher potentials. The presence of the capping ligand made it difficult to establish any cooperativity between the two metals to catalyze the EOR. Thus, similar Ir@Pt NPs were also made without a capping ligand. Unexpectedly, little to no enhancement of the EOR catalytic activity was found for these core@shell NPs. The findings were compared to similar studies of methanol oxidation.
Inhomogeneous spin diffusion in traps with cold atoms

description: The spin diffusion and damped oscillations are studied in the collision of two spin polarized clouds of cold atoms with resonant interactions. The strong density dependence of the diffusion coefficient leads to inhomogeneous spin diffusion that changes from central to surface spin flow as the temperature increases. The inhomogeneity and the smaller finite trap size significantly reduce the spin diffusion rate at low temperatures. The resulting spin diffusion rates, spin drag and initial damped oscillations are compatible with measurements at low to high temperatures for resonant attractive interactions but are incompatible with a metastable ferromagnetic phase.

description: Η ξυλώδης βιομάζα είναι μια ανανεώσιμη πηγή ενέργειας με την ιδιότητα ότι, όταν καεί έχει μηδενικό αποτύπωμα άνθρακα, καθώς απελευθερώνεται το διοξείδιο του άνθρακα το οποίο είχε δεσμευτεί κατά τη φωτοσύνθεση. Το πιο κοινότυπο καύσιμο από ξυλώδη βιομάζα είναι το πέλλετ, το οποίο συναντάται τόσο σε οικιακή όσο και βιομηχανική εφαρμογή. Η κύρια πηγή πρώτης ύλης είναι το πριονίδι που παράγεται από τη δραστηριότητα των πριστηρίων. . Η μεγάλη ζήτηση όμως έχει οδηγήσει σε αναζήτηση και άλλων πρώτων υλών, όπως η υπολειμματική βιομάζα από την εντατική γεωργία. Σε αυτή την έρευνα διερευνώνται κάποιες ιδιότητες που πρέπει να διέπουν τα πέλλετ, για πέλλετ που έχουν δημιουργηθεί από βιομάζα που προέκυψε από κλάδευση ελαιόδεντρων (ποικιλία Χαλκιδικής), η οποία καλλιεργείται σε μεγάλες εκτάσεις κυρίως στη Βόρειο Ελλάδα. Σε αυτήν την έρευνα, θα διερευνηθούν ορισμένες βασικές ιδιότητες σε σύμπηκτα που δημιουργούνται από βιομάζα που προέρχεται από κλάδεμα ελαιόδεντρων (Olea europea L.) και συγκεκριμένα κλαδιών διαφορετικής διαμέτρου (μικρό, μεσαίο, χοντρό), φύλλα και ξύλο από τον κορμό της ελιάς. , που είναι είδος που καλλιεργείται εντατικά κυρίως στη Βόρεια Ελλάδα. Θα γίνουν μετρήσεις σχετικά με την περιεκτικότητα σε τέφρα, την περιεκτικότητα σε υγρασία, στα υλικά μεμονωμένα και σε μείγματα, καθώς και δημιουργία σύμπηκτων σε μονή πρέσα pellet προκειμένου να μελετηθεί η μηχανική αντοχή, η πυκνότητα, η σταθερότητα των διαστάσεων και άλλες ιδιότητες των σύμπηκτων
description: Woody biomass is a renewable natural resource with the particularity that when burned it has a zero carbon footprint since it releases the carbon dioxide it has captured during photosynthesis. The most common form of solid wood biomass fuel is pellets, which meet both domestic and industrial applications. The main source for the raw material of pellets is sawdust from sawmills. However, the high demand has led to the search for other raw materials, such as residual biomass from intensive agriculture. In this research, some crucial properties will be investigated in pellets created from biomass obtained from pruning of olive trees (Olea europea L.) and specifically of different diameter branches (small, medium, high), leaves and wood from the trunk of olive trees, which is a species intensively cultivated mainly in Northern Greece. Measurements will be made regarding the ash content, moisture content, in the materials individually and in mixtures, as well as the creation of pellets in a single pellet die press in order to study the mechanical strength, density, dimensional stability and other properties of the prepared pellets

description: The aim of the thesis was to study Outdoor Education and to highlight this teaching approach as a useful and excellent tool in the field of Catechetical and Christian Pedagogy. We examined the subject we wanted to teach from all its possible aspects. The topic was "creation" and biblical and patristic texts were used to gather information. We then detailed the characteristics of Outdoor Education, as well as its possibilities and limitations. We also referred to the catechetical assemblies of children and how Outdoor Education can be applied. We also dealt with the contribution of this teaching approach to the child's development and the benefits and advantages it can provide. Finally, we implemented the program in a catechetical gathering of children entitled "Pathway to God" using the Outdoor Education approach

description: Let k be a field of characteristic zero. Let phi be a k-endomorphism of the polynomial algebra k[x_1,...,x_n]. It is known that phi is an automorphism if and only if it maps irreducible polynomials to irreducible polynomials. In this paper we show that phi satisfies the jacobian condition if and only if it maps irreducible polynomials to square-free polynomials. Therefore, the Jacobian Conjecture is equivalent to the following statement: every k-endomorphism of k[x_1,...,x_n], mapping irreducible polynomials to square-free polynomials, maps irreducible polynomials to irreducible polynomials.

Dynamic Limits on Planar Libration-Orbit Coupling Around an Oblate Primary

Year: 2012
Subjects: subject: Earth and Planetary Astrophysics (astro-ph.EP)

description: This paper explores the dynamic properties of the planar system of an ellipsoidal satellite in an equatorial orbit about an oblate primary. In particular, we investigate the conditions for which the satellite is bound in librational motion or when the satellite will circulate with respect to the primary. We find the existence of stable equilibrium points about which the satellite can librate, and explore both the linearized and non-linear dynamics around these points. Absolute bounds are placed on the phase space of the libration-orbit coupling through the use of zero-velocity curves that exist in the system. These zero-velocity curves are used to derive a sufficient condition for when the satellite's libration is bound to less than 90 degrees. When this condition is not satisfied so that circulation of the satellite is possible, the initial conditions at zero libration angle are determined which lead to circulation of the satellite. Exact analytical conditions for circulation and the maximum libration angle are derived for the case of a small satellite in orbits of any eccentricity.

description:
Pay-it-forward incentives involve having a person receive a free test with community-generated messages and then asking if those who received a free test would like to donate money to support others to receive free testing. Here we undertook a two-arm cluster-randomized trial to evaluate pay-it-forward incentives with active community participation to promote hepatitis B virus (HBV) and hepatitis C virus (HCV) testing among men who have sex with men in China. Men randomized to the pay-it-forward arm received free HBV and HCV testing and were offered a chance to pay-it-forward by donating money to support the testing of another anonymous person. Each participant paid for their HCV and HBV test at 7.7 USD per test in the standard-of-care arm. The primary outcome was the proportion of men who tested for HBV and HCV. Between 28 March and 6 November 2021, 32 groups (10 men per group) of men were randomized to the pay-it-forward (n = 160, 16 clusters) and standard-of-care (n = 162, 16 clusters) arms, respectively. HBV and HCV rapid testing were higher in the pay-it-forward arm (59.4%) than in the standard-of-care arm (25.3%) (proportion difference 35.2%, 95% confidence interval 24.1–46.3%). No adverse events were reported. The community-led pay-it-forward incentives improved HBV and HCV testing among men who have sex with men. Clinical Trial registration: ChiCTR 2100046140.

description: We describe a system for localizing and separating multiple sound sources from a reverberant two-channel recording. It consists of a probabilistic model of interaural level and phase differences and an EM algorithm for finding the maximum likelihood parameters of this model. By assigning points in the interaural spectrogram probabilistically to sources with the best-fitting parameters and then estimating the parameters of the sources from the points assigned to them, the system is able to separate and localize more sound sources than there are available channels. It is also able to estimate frequency-dependent level differences of sources in a mixture that correspond well to those measured in isolation. In experiments in simulated anechoic and reverberant environments, the proposed system improved the signal-to-noise ratio of target sources by 2.7 and 3.4dB more than two comparable algorithms on average.

Talking across boundaries: interracial deliberation
Creators: name: Beauvais, Edana
Publisher: name: University of British Columbia
Year: 2011

description: The purpose of my work is to clarify the contingencies that enable the normative expectations of deliberative democracy in the context of interracial deliberation, as well as to understand the conditions under which deliberation contributes to the contrary, and catalyzes racial prejudice and group polarisation. I argue that understanding how interracial deliberation can promote the expectations of deliberative theory, such as the identification of common interests or mutual-recognition across racial divides, entails understanding the context under which discourse takes place. For instance, I show that communication between members of different races is less likely to promote beneficial outcomes when discussion partners suffer from economic or material insecurity, and if resultant interracial interactions are characterized by fear, distrust, or hatred. The role of emotions is central to my understanding of the possibility for successful discourse. In this piece I justify the use of deliberative theory as a framework for understanding race-relations and white values and opinions. I also consider the macro-level antecedents to affect; that is, I consider the structural features of American society that shape the feelings whites harbour toward blacks. The importance of affect for deliberation is reviewed. The effects of interracial socialisation and diversity in communication networks on value and opinion formation are also considered. In this piece I employ original research to clarify the relationship between affect, interracial socialisation, and the racial attitudes of whites. Using data from the Detroit Area Study (2004) I find that variables measuring both the social and economic well-being of neighbourhoods, as well as a variable measuring beliefs about ‘special favours’ for blacks, have a significant impact on the feelings whites harbour toward blacks.

Year: 2000
Subjects: Computer science

description: The automated extraction of photorealistic 3-D models of the world that can be used in applications such as virtual reality, tele-presence, digital cinematography and urban planning, is the focus of this paper. The combination of range (dense depth estimates) and image sensing (color information) provides data-sets which allow us to create photorealistic models of high quality. The challenges are the simplification of the 3-D data set, the extraction of meaningful features in both the range and 2-D images and the fusion of those data-sets using the extracted features. We address all these challenges and provide results on data we gathered in outdoor scenes by a range and image sensor based on a mobile robot. Our ultimate goal is an autonomous 3-D model creation system which minimizes the amount of human interaction.

title: Internet-Wide Evaluations of Security and Vulnerabilities
Creators: name: Dai, Tianxiang
Publisher: name: UNSPECIFIED

description: The Internet significantly impacts the world culture. Since the beginning, it is a multilayered system, which is even gaining more protocols year by year. At its core, remains the Internet protocol suite, where the fundamental protocols such as IPv4, TCP/UDP, DNS are initially introduced. Recently, more and more cross-layer attacks involving features in multiple layers are reported. To better understand these attacks, e.g. how practical they are and how many users are vulnerable, Internet-wide evaluations are essential. In this cumulative thesis, we summarise our findings from various Internet-wide evaluations in recent years, with a main focus on DNS. Our evaluations showed that IP fragmentation poses a practical threat to DNS security, regardless of the transport protocol (TCP or UDP). Defense mechanisms such as DNS Response Rate Limiting could facilitate attacks on DNS, even if they are designed to protect DNS. We also extended the evaluations to a fundamental system which heavily relies on DNS, the web PKI. We found that Certificate Authorities suffered a lot from previous DNS vulnerabilities. We demonstrated that off-path attackers could hijack accounts at major CAs and manipulate resources there, with various DNS cache poisoning attacks. The Domain Validation procedure faces similar vulnerabilities. Even the latest Multiple-Validation-Agent DV could be downgraded and poisoned. On the other side, we also performed Internet-wide evaluations of two important defence mechanisms. One is the cryptographic protocol for DNS security, called DNSSEC. We found that only less than 2% of popular domains were signed, among which about 20% were misconfigured. This is another example showing how poorly deployed defence mechanisms worsen the security. The other is ingress filtering, which stops spoofed traffic from entering a network. We presented the most completed Internet-wide evaluations of ingress filtering, which covered over 90% of all Autonomous Systems. We found that over 80% of them were vulnerable to inbound spoofing.

description: In the considered linear Gaussian sensor scheduling problem, only one sensor out of a set of sensors performs a measurement. To minimize the estimation error over multiple time steps in a computationally tractable fashion, the so-called information-based pruning algorithm is proposed. It utilizes the information matrices of the sensors and the monotonicity of the Riccati equation. This allows ordering sensors according to their information contribution and excluding many of them from scheduling. Additionally, a tight lower is calculated for branch-and-bound search, which further improves the pruning performance.

As with so much else in the foundations of Eastern Christian thought, what we rightly see as a distinctly new Byzantine use of the term Philanthropy to designate the appropriate Christian response to human need, the divinely inspired human movement to compassion, and the God-graced desire to establish justice, is actually a synthesis of classical thought on matters of civilized valued. These values were forged in a creative interplay as these concepts were brought into a dynamic synthesis with the New Testament and early Patristic notions of the divine Kenosis and the merciful Christ…

description: We have developed a system that breaks input speech into segments using an acoustic similarity measure. The aim is to detect the time points where the acoustic characteristics change, usually due to speaker changes but also resulting from changes in the acoustic environment. We have also developed a system to cluster the segments generated by the first system into clusters composed of homogeneous acoustic conditions. In this paper, we present a technique to improve the robustness of the acoustic change detection by feeding back the results of the segment clustering, exploiting the extra information available in the distance between the two clusters to which the segments belong. The interaction between the acoustic change detection and clustering systems gives us a substantial improvement over results previously reported on the 1997 Hub-4 Broadcast News test set that we employed: Feedback of clustering information improved the Equal Error Rate (EER) of our acoustic change detection (ACD) system from 26.5% to 18%.

description: Antikörper, die gegen HLA-Merkmale eines Spenders gerichtet sind, repräsentieren die Hauptursache für Transplantatabstoßungen. Zur Detektion dieser Donor-spezifischen Antikörper wurde der funktionelle Lymphozytotoxizitätstest entwickelt, dessen Validität in höchstem Maße von der Vitalität verfügbarer Spenderlymphozyten sowie von weiteren Störfaktoren abhängt. Um zu beweisen, dass der ELISA-basierende Kreuztest ein alternatives Verfahren darstellt, welches auch mit langjährig gelagertem nicht-vitalem Spendermaterial durchgeführt werden kann, wurden 33 Seren von herz- und lungentransplantierten Patienten retrospektiv unter Verwendung des Kreuztest-ELISA auf den Nachweis von DSA untersucht und mit korrespondierenden virtuellen Kreuztestergebnissen verglichen. Erstmalig in der gesamten Historie der Transplantationsdiagnostik zeigen die Untersuchungen einen methodischen Weg auf, auch langjährig asserviertes Spendermaterial für einen Kreuztest in der Rejektionsdiagnostik zu verwenden.
description: Antibodies directed against human leucocyte antigens of the given donors represent the main reason for (hyper-) acute rejections of allo-grafted organs. In order to detect these anti-bodies the cellular CDC-crossmatch was established as standard procedure. However, it is characterized by several drawbacks such as the requirement of vital lymphocytes and its high susceptibility to artificial factors frequently leading to false positive results. The aim of the current investigation was to demonstrate that ELISA-based cross-matching represents an adequate alternative procedure leading to valid results in cases with no vital lymphocytes available. In this context we analyzed 33 sera and their corresponding donors’ deep-frozen leukocyte pellets. Comparing these outcomes with the results of virtual cross-matching we first provided evidence that ELISA-based cross-matching provides the option to routinely perform de facto cross-matching through the use of long term-stored donors’ materials.

description: We introduce two methods for the registration of range images when a prior estimate of the transformation between views is not available and the overlap between images is relatively small. The methods are an extension to the work of Gueziec and Ayache (1994) and Turk and Levoy (1994) and consists of 2 stages. First, we find the initial estimated transformation by extracting and matching 3D space curves from different scans of the same object. If no salient features are available on the object we use fiducial marks to find the initial transformation. This allows us to always find a satisfactory and even highly accurate transformation independent of the geometry of the object. Second, we apply a modified iterative closest points algorithm (ICP) to improve the accuracy of registration. We define a weighted distance function based on surface curvature which can reduce the number of iterations and requires a less accurate initial estimate of the transformation.

description: Site 1073 constitutes one of four second-priority sites approved for drilling that were to be undertaken in the event that either time allowed or that operations had to be curtailed at both primary shelf sites. With 5 days remaining on Leg 174A, the decision was made to move to the slope, because it seemed unlikely that at Sites 1071 and 1072 it would be possible to reach objectives deeper than surface m1(s) without unreasonable risk of equipment loss because of unstable hole conditions. Site 1073 was designed to drill as deeply as time would allow into “Icehouse” sediments (Oligocene and younger) at a location where the physical stratigraphy could be related to sequence boundaries traced seaward from the shelf. The objective at Site 1073 is to provide the age and deep-water facies control for surfaces that in shallow water can yield paleobathymetry and facies characterization relevant to determining the history and geologic impact of glacial-eustatic change.

description: Η εφαρμογή της έκτακτης σχολικής εξ αποστάσεως εκπαίδευσης, που έλαβε χώρα τα σχολικά έτη 2019-20 και 2021-22 εξαιτίας της πανδημίας του κορονοϊού έγινε υπό βιαστικές και δίχως οργάνωση συνθήκες, γεγονός που επέφερε αναστάτωση και άγχος στους εκπαιδευτικούς. Σκοπός της παρούσας έρευνας ήταν η διερεύνηση των απόψεων 15 εκπαιδευτικών, οι οποίοι εκείνη την περίοδο δίδαξαν με την εξ αποστάσεως μέθοδο διδασκαλίας σε δημόσια σχολεία της χώρας. Διερευνήθηκαν μέσω συνεντεύξεων οι απόψεις των εκπαιδευτικών για το άγχος που βίωσαν εκείνη την περίοδο, εστιάζοντας στον τρόπο εκδήλωσής του, στους παράγοντες δημιουργίας του, στις συνέπειες του, αλλά και στους τρόπους αντιμετώπισής του. Επίσης, εξετάστηκε αν τα επίπεδα άγχους των εκπαιδευτικών άγγιζαν τα όρια της επαγγελματικής εξουθένωσης. Τα αποτελέσματα έδειξαν πως οι εκπαιδευτικοί ένιωθαν ιδιαίτερο άγχος κατά τη διάρκεια της εξ αποστάσεως διδασκαλίας και το άγχος τους ήταν πολυπαραγοντικό. Τα συμπτώματα του άγχους αφορούσαν τόσο την ψυχική όσο και τη σωματική υγεία τους. Οι συνέπειες του άγχους ήταν εμφανείς στην ψυχολογία των εκπαιδευτικών, αλλά και στις διαπροσωπικές σχέσεις με τους οικείους και τους μαθητές τους. Ο βασικότερος τρόπος αντιμετώπισης του άγχους για τους εκπαιδευτικούς ήταν η υποστήριξη που έλαβαν από το οικογενειακό, φιλικό και επαγγελματικό περιβάλλον τους
description: The implementation of the emergency school distance education, which took place in the school years 2019-20 and 2021-22 due to the coronavirus pandemic, was done in a hasty and unorganized manner, which caused disruption and stress to teachers. The purpose of this research was to investigate the opinions of 15 teachers, who at that time taught with the distance teaching method in public schools of the country. Through interviews, the teachers' views on the stress they experienced during that period were investigated, focusing on the way it manifested, the factors that created it, its consequences, but also the ways to deal with it. Also, it was examined whether the stress levels of the teachers reached the limits of professional burnout. The results showed that teachers felt particularly stressed during distance teaching and their stress was multifactorial. Symptoms of stress related to both their mental and physical health. The consequences of stress were evident in the teachers' psychology, but also in the interpersonal relationships with their relatives and students. The main way to deal with stress for teachers was the support they received from their family, friends and professional environment

description: Site 1072 is the second of two sites approved for JOIDES Resolution drilling on the New Jersey continental shelf; together with Site 1071, it forms part of a transect of holes from the slope (Ocean Drilling Program [ODP] Leg 150) to coastal outcrops (Legs 150X and 174AX) that constitute the Mid-Atlantic Sea-level Transect. The primary goals of the transect are to: (1) date sequence boundaries of Oligocene to Holocene age and compare this stratigraphic record with the timing of glacial eustatic changes inferred from deep-sea d18O variations; (2) place constraints on the amplitudes and rates of sea-level change that may have been responsible for unconformity development; (3) assess the relationships between depositional facies and sequence architecture; and (4) provide a baseline for future scientific ocean drilling that will address the effects and timing of sea-level changes on this and other passive margins. Site 1072 is ~3.5 km seaward of Site 1071 and coincides with the rollover or breakpoint in sequence boundary m0.5(s). This site provides information primarily about upper Miocene and younger strata and permits a comparison, in the direction of progradation, with the succession at Site 1071.

description: We describe and discuss our recent work developing a database, methodology and ground truth for the evaluation of automatic techniques for music similarity. Our database consists of acoustic and textual 'Web-mined' data covering 400 popular artists. Of note is our technique of sharing acoustic features rather than raw audio to avoid copyright problems. Our evaluation methodology allows any data source to be regarded as ground truth and can highlight which measure forms the best collective ground truth. We additionally describe an evaluation methodology that is useful for data collected from people in the form of a survey about music similarity. We have successfully used our database and techniques to evaluate a number of music similarity algorithms.

description: This paper introduces the monographic issue of Linguistic Typology at the Crossroads entitled “Language contact and non-convergent change: cases from Africa”, edited by Pierpaolo Di Carlo and Pius W. Akumbu. After briefly outlining non-convergent change under contact with a special attention to African settings, it deals with the fact that the languages discussed in the monographic issue have been spoken for generations in contexts of small-scale multilingualism. This is a key aspect to consider since small-scale multilingualism is a type of multilingualism that is overall little known as to its possible effects at the level of language change. The paper then addresses methodological aspects related to the study of non-convergent change in contact situations and introduces the novel concept of “correlated dissimilarity”. A call for the collection of new and more comprehensive data in the field as the only possible way to test the hypotheses raised in this volume concludes this introduction.
