description: Από την εφεύρεση ακόμα του μέσου της Φωτογραφίας, και ειδικότερα μετά από την γενικότερη εδραίωσή του, δημιουργήθηκε μία ιδιαιτέρως θεμελιώδης σχέση μεταξύ αυτού και του τομέα της Αρχιτεκτονικής. Μία αμφίδρομα κερδοφόρα
σχέση, αφού και τα δύο μέλη μπορούσαν να εκλάβουν κάτι από αυτή. Το κέρδος αυτό ήταν αξιόλογο, ειδικότερα για την Αρχιτεκτονική, που από το αποτέλεσμα που προέκυπτε από την συνεργασία τους εκλάμβανε την ευκαιρία να διαδώσει τα έργα της, κάτι που μέχρι πριν ήταν αδύνατο, αλλά και να διαβεβαιώσει την επιβίωσή τους στο χρόνο, ανεξάρτητα από την διάρκεια ζωής του ίδιου του εκάστοτε αρχιτεκτονήματος.
Αυτό ακριβώς το αποτέλεσμα της αλληλεπίδρασης των δύο τομέων είναι που εξετάζουμε σε αυτή την εργασία. Καθ’ όλη την έκτασή της, θα επικεντρωθούμε στην Φωτογραφία ως μέσο αναπαράστασης της Αρχιτεκτονικής, τον ρόλο της στην πορεία και την εξέλιξή της, αλλά και την αλληλεπίδραση των δύο τεχνών τόσο μεταξύ τους, όσο και με τον θεατή τους. Βασικότερό μας άξονα όμως, θα αποτελέσει η δυνατότητα ανάλυσης από τον θεατή του τελικού αποτελέσματος που παράγει η συνεργασία τους, η εξέταση δηλαδή των αρχιτεκτονικών φωτογραφιών, καθώς και η σύγκριση αυτού που αντικατοπτρίζουν με το
αρχιτεκτόνημα που είχε επιλεχθεί ως θεματολογία από τον φωτογράφο, ή και φωτογράφους, με διαφορετικές προσεγγίσεις.

description: Evaluating and understanding the inappropriateness of chatbot behaviors can be challenging, particularly for chatbot designers without technical backgrounds. To democratize the debugging process of chatbot misbehaviors for non-technical designers, we propose a framework that leverages dialogue act (DA) modeling to automate the evaluation and explanation of chatbot response inappropriateness. The framework first produces characterizations of context-aware DAs based on discourse analysis theory and real-world human-chatbot transcripts. It then automatically extracts features to identify the appropriateness level of a response and can explain the causes of the inappropriate response by examining the DA mismatch between the response and its conversational context. Using interview chatbots as a testbed, our framework achieves comparable classification accuracy with higher explainability and fewer computational resources than the deep learning baseline, making it the first step in utilizing DAs for chatbot response appropriateness evaluation and explanation.

description: Η εργασία αυτή μελετά τη σχέση αεροδρομίου και πόλης εστιάζοντας στα σύγχρονα μοντέλα ανάπτυξης του ευρύτερου χώρου του αεροδρομίου και τη σχέση που αναπτύσσουν με την πόλη. Αρχικά προσδιορίζεται το τι περιγράφει ο όρος αεροδρόμιο – τι λειτουργίες περιλαμβάνει αεροπορικές και μη – και πως ο όρος αυτός έχει διευρυνθεί με την πάροδο του χρόνου. Στη συνέχεια, αφού τονιστεί η σημασία του δικτύου μεταφορών στην ανάπτυξη της πόλης – και λαμβάνοντας υπόψιν και την πρωτοκαθεδρία των αερομεταφορών στη σύγχρονη εποχή – μελετώνται τα σύγχρονα μοντέλα ανάπτυξης αεροδρομίων σε σχέση με την πόλη. Εξετάζονται λοιπόν τα συστήματα Airport-city, Aerotropolis, Airport-corridor, Airea και Airport urbanism. Μέσα από τα παραπάνω μοντέλα ανάπτυξης και από τα παραδείγματα διαφαίνεται και η αμφίπλευρα τροφοδοτούμενη σχέση μεταξύ αεροδρομίου και πόλης, μελετώνται οι συνέπειες της εφαρμογής των δομών αυτών και σκιαγραφούνται τα προβλήματα που προκύπτουν. Τέλος, γίνεται αναφορά στη σημασία της ένταξης του σχεδιασμού του αεροδρομίου στο πολεοδομικό και ρυθμιστικό σχέδιο σε τοπικό και εθνικό επίπεδο. Αυτή την αντίληψη στηρίζουν και οι θεωρίες και τα παραδείγματα που έχουν χρησιμοποιηθεί, όπως το μοντέλο του Feeder Airport και της mini Aerotrop¬olis, και τη σχέση που τελικά έχει το αεροδρόμιο με την παγκοσμιοποιημένη πόλη.
description: This paper studies the relationship between the airport and the city, focusing on the modern development models of the airport's wider area and the relationship they are developing with the city. Initially, what is the term airport - what functions includes air and non - air - is described and how this term has widened over time. Then, having emphasized the importance of the transport network to the development of the city - and considering the dominance of aviation in modern times - modern aerodrome development models are being studied in relation to the city. Therefore, Airport-City, Aerotropolis, Airport-corridor, Airea and Airport urbanism are being considered. Through the above development models and from the examples, there is also a bi-directional link between airport and city, the implications of the implementation of these structures are studied and the problems that arise are outlined. Finally, reference is made to the importance of integrating airport design into the urban and regulatory plan at local and national level. This perception is supported by the theories and examples that have been used, such as the model of Feeder Airport and mini Aerotropolis, and the affiliation that the airport has with the globalized city

description: To validate the safety of automated vehicles (AV), scenario-based testing aims to systematically describe driving scenarios an AV might encounter. In this process, continuous inputs such as velocities result in an infinite number of possible variations of a scenario. Thus, metamodels are used to perform analyses or to select specific variations for examination. However, despite the safety criticality of AV testing, metamodels are usually seen as a part of an overall approach, and their predictions are not questioned. This paper analyzes the predictive performance of Gaussian processes (GP), deep Gaussian processes, extra-trees, and Bayesian neural networks (BNN), considering four scenarios with 5 to 20 inputs. Building on this, an iterative approach is introduced and evaluated, which allows to efficiently select test cases for common analysis tasks. The results show that regarding predictive performance, the appropriate selection of test cases is more important than the choice of metamodels. However, the choice of metamodels remains crucial: Their great flexibility allows BNNs to benefit from large amounts of data and to model even the most complex scenarios. In contrast, less flexible models like GPs convince with higher reliability. Hence, relevant test cases are best explored using scalable virtual test setups and flexible models. Subsequently, more realistic test setups and more reliable models can be used for targeted testing and validation.

description: Excerpts from the report Introduction: The use of biphenyl in vapor form is generally considered effective in reducing decay in citrus fruits during marketing. In spite of the use of biphenyl, reports of excessive decay in fruit exported to European markets have been received frequently. This led representatives of the American citrus industry and related industries to request the Agricultural Marketing Service and the California Citrus Experiment Station to investigate ways of improving the effectiveness of biphenyl in reducing decay and s[p]oilage. For this purpose three test shipments of lemons were made from Los Angeles to Hamburg via the Panama Canal during the summer of 1959. Three corresponding static tests were made with fruit from the same lots at the citrus experiment station at Riverside, Calif., using stationary model refrigerated cars. A fourth static test was made on oranges as well as lemons. These tests were made to obtain additional data on (1) the usefulness of biphenyl in reducing decay of citrus fruit during transit, and for 2 weeks after unloading, a period long enough to provide for distribution through the usual market channels; (2) the desirability of ventilating holes in the fiberboard containers, and (3) biphenyl accumulation in the fruit as influenced by carton ventilation, transit and storage time, and temperature. This study is part of a broad program of research aimed at expanding the market for agricultural products.

description: Extensive medical, public health, and social science research have focused on cataloguing male–female differences in human health. Unfortunately, much of this research unscientifically and unquestionably attributes these differences to biological causes – as exemplified in the Institute of Medicine’s conclusion that “every cell has a sex.” In this manuscript we theorize the entanglement of sex and gender in human health research and articulate good practice guidelines for assessing the role of biological processes – along with social and biosocial processes – in the production of non-reproductive health differences between and among men and women. There are two basic tenets underlying this project. The first is that sex itself is not a biological mechanism and the second is that “sex” and “gender” are entangled, and analyses should proceed by assuming that measures of sex are not pristine, but include effects of gender. Building from these tenets – and using cardiovascular disease as a consistent example – we articulate a process that scientists and researchers can use to seriously and systematically assess the role of biology and social environment in the production of health among men and women. We hope that this intervention will be one further step toward understanding the complexity and nuance of health outcomes, and that this increased knowledge can be used to improve human health.
Vom Wert der Tradition - Christliche Überlieferung und Bildung in der pluralen Gesellschaft

description: Christentum und Kirche gehören ebenso wie die Überlieferungen der klassischen Antike untrennbar zur europäischen Kultur. Welche Bedeutung die christliche Tradition jedoch im Rahmen einer sich als plural beschreibenden Gesellschaft einnehmen soll, wird kontrovers diskutiert. Wie mit den Überlieferungen angesichts von Säkularisierung und Individualisierung umgegangen werden kann, ist eine wichtige Frage moderner Religionsdidaktik und Bildungsforschung, die die Selbstbildung des Menschen zum Ziel haben. In einem solchen Kontext kann Tradition zu einer Perspektive werden, die dem Menschen Freiräume eröffnet, indem sie der scheinbar normativen Kraft des Faktischen widerspricht. Als pädagogische und didaktische Konsequenz ist daher ein nicht-traditionaler Umgang mit Tradition zu gestalten.

description: We have observed 79 supernova remnants (SNRs) with the Urumqi 25m telescope at 6cm during the Sino-German 6cm polarization survey of the Galactic plane. We measured flux densities of SNRs at 6cm, some of which are the first ever measured or the measurements at the highest frequency, so that we can determine or improve spectra of SNRs. Our observations have ruled out spectral breaks or spectral flattening that were suggested for a few SNRs, and confirmed the spectral break of S147. By combining our 6cm maps with 11cm and 21cm maps from the Effelsberg 100 m telescope, we calculated the spectral index maps of several large SNRs. For many remnants we obtained for the first time polarization images, which show the intrinsic magnetic field structures at 6cm. We disapproved three objects as being SNRs, OA184, G192.8-1.1 and G16.8-1.1, which show a thermal spectrum and no polarization. We have discovered two large supernova remnants, G178.2-4.2 and G25.1-2.3., in the survey maps.

description: Waves entering a spatially uniform lossy medium typically undergo exponential decay, arising from either the energy loss of the Beer-Lambert-Bouguer transmission law or the evanescent penetration during reflection. Recently, exceptional point singularities in non-Hermitian systems have been linked to unconventional wave propagation, such as the predicted extremely spatially broad constant-intensity guided modes. Despite such promises, the possibility of decay-free wave propagation in a purely lossy medium has been neither theoretically suggested nor experimentally realized until now. Here we discover and experimentally demonstrate decay-free wave propagation accompanied by a striking uniformly distributed energy loss across arbitrary thicknesses of a homogeneous periodically nanostructured waveguiding medium with exceptional points. Predicted by coupled-mode theory and supported by fully vectorial electromagnetic simulations, hundreds-of-waves deep penetration manifesting spatially constant radiation losses are experimentally observed in photonic slab waveguides. The uniform, decay-free radiative energy loss is measured across the entire structured waveguide region, regardless of its length. While the demonstrated constant-intensity radiation finds an immediate application for generating large, uniform and surface-normal free-space plane waves directly from the photonic chip surface, the uncovered decay-free wave phenomenon is universal and holds true across all domains supporting physical waves, opening new horizons for dispersion-engineered materials empowered by exceptional point physics.

description: This paper presents an analytical model to quantify the measured noise in a cryogenic bolometer readout circuit. The model includes the contributions from the bias resistors and sensor resistors, voltage and current noise of amplifier, and cable capacitance. The model parameters are empirically estimated using frequency domain analysis of the measured noise data of indigenously developed Neutron Transmutation Doped (NTD) Ge sensors. The model is shown to describe noise data for NTD Ge sensors over a wide range of resistances corresponding to temperatures in the range 20 - 70 mK. Relative contributions of different components are discussed and it is shown that the contribution to the overall noise from the differential amplifier at 300 K is the dominant source. It is observed that the amplifier flicker noise is significantly lower than that specified in the amplifier datasheet. The present study also indicates that a desirable value of resistance of NTD sensor (R$_{NTD}$) from noise considerations is $\leq$ 1 G$Ω$ at $sim$ 20 mK.
description: Replaced the existing time domain analysis with frequency domain analysis as that is a better representation of noise data. The older manuscript included work done on NTD Ge sensors only, while the replacement manuscript has work done on NTD and SMD sensors both with the results verifed over a wider range of resistance for NTD Ge sensors

description: Formalizing an old desire of Einstein, "psi-epistemic theories" try to reproduce the predictions of quantum mechanics, while viewing quantum states as ordinary probability distributions over underlying objects called "ontic states." Regardless of one's philosophical views about such theories, the question arises of whether one can cleanly rule them out, by proving no-go theorems analogous to the Bell Inequality. In the 1960s, Kochen and Specker (who first studied these theories) constructed an elegant psi-epistemic theory for Hilbert space dimension d=2, but also showed that any deterministic psi-epistemic theory must be "measurement contextual" in dimensions 3 and higher. Last year, the topic attracted renewed attention, when Pusey, Barrett, and Rudolph (PBR) showed that any psi-epistemic theory must "behave badly under tensor product." In this paper, we prove that even without the Kochen-Specker or PBR assumptions, there are no psi-epistemic theories in dimensions d>=3 that satisfy two reasonable conditions: (1) symmetry under unitary transformations, and (2) "maximum nontriviality" (meaning that the probability distributions corresponding to any two non-orthogonal states overlap). This no-go theorem holds if the ontic space is either the set of quantum states or the set of unitaries. The proof of this result, in the general case, uses some measure theory and differential geometry. On the other hand, we also show the surprising result that without the symmetry restriction, one can construct maximally-nontrivial psi-epistemic theories in every finite dimension d.

description: The paper investigates two new use cases for the Boris Spectral Deferred Corrections (Boris-SDC) time integrator for plasma simulations. First, we show that using Boris-SDC as a particle pusher in an electrostatic particle-in-cell (PIC) code can, at least in the linear regime, improve simulation accuracy compared with the standard second order Boris method. In some instances, the higher order of Boris-SDC even allows a much larger time step, leading to modest computational gains. Second, we propose a modification of Boris-SDC for the relativistic regime. Based on an implementation of Boris-SDC in the \textsc{runko} PIC code, we demonstrate for a relativistic Penning trap that Boris-SDC retains its high order of convergence for velocities ranging from $0.5c$ to $>0.99c$. We also show that for the force-free case where acceleration from electric and magnetic field cancel, Boris-SDC produces less numerical drift than Boris.

description: Seven rocky planets orbit the nearby dwarf star TRAPPIST-1, providing a unique opportunity to search for atmospheres on small planets outside the Solar System (Gillon et al., 2017). Thanks to the recent launch of JWST, possible atmospheric constituents such as carbon dioxide (CO2) are now detectable (Morley et al., 2017, Lincowski et al., 2018}. Recent JWST observations of the innermost planet TRAPPIST-1 b showed that it is most probably a bare rock without any CO2 in its atmosphere (Greene et al., 2023). Here we report the detection of thermal emission from the dayside of TRAPPIST-1 c with the Mid-Infrared Instrument (MIRI) on JWST at 15 micron. We measure a planet-to-star flux ratio of fp/fs = 421 +/- 94 parts per million (ppm) which corresponds to an inferred dayside brightness temperature of 380 +/- 31 K. This high dayside temperature disfavours a thick, CO2-rich atmosphere on the planet. The data rule out cloud-free O2/CO2 mixtures with surface pressures ranging from 10 bar (with 10 ppm CO2) to 0.1 bar (pure CO2). A Venus-analogue atmosphere with sulfuric acid clouds is also disfavoured at 2.6 sigma confidence. Thinner atmospheres or bare-rock surfaces are consistent with our measured planet-to-star flux ratio. The absence of a thick, CO2-rich atmosphere on TRAPPIST-1 c suggests a relatively volatile-poor formation history, with less than 9.5 +7.5 -2.3 Earth oceans of water. If all planets in the system formed in the same way, this would indicate a limited reservoir of volatiles for the potentially habitable planets in the system.

description: Radar Wind Profilers (RWP) are well-established instruments for the probing of the atmospheric boundary layer, with the immense advantage of long-range and all-weather operation capability. One of their main limitations, however, is a relatively long integration time compared to other instruments such as lidars. In the context of L-band RWP we show that the use of Autoregressive (AR) modeling for the antenna signals combined with the Maximum Entropy Method (MEM) allows for a correct estimation of radial wind velocity profiles even with very short time samples. A systematical analysis of performance is made with the help of synthetic data. These numerical results are further confirmed by an experimental dataset acquired near the landing runways of Paris Charles de Gaulle (CDG) Airport, France, and validated using a colocated optical lidar at the Aerological station of Payerne, Switzerland. It is found that the AR-MEM approach can successfully derive reliable wind estimates using integration times as short as 2.5 s where the classical spectral approach can barely provide any measurement. In addition, the technique helps mitigating the impact of uncooperative flyers in the processing of the atmospheric echo, leading to a more successful application of the wind estimation algorithm.

description: A number of researchers have pointed out that less is known about occupational determinants of health in women than in men. The authors examine inventories of ongoing Canadian research and of recent scientific publications in order to identify trends in the approaches used to study women's occupational health (WOH). We also consider conceptual issues in the treatment of the sex and gender of subjects. We observe that women have been the subject of relatively few investigations of occupational health in the natural or biomedical sciences and that studies of WOH have concentrated on the health care professions and on psychosocial stressors, with a deficit in toxicological and physiological studies. We use recent studies of mercury exposure in chloralkali process plants and of musculoskeletal disorders among office workers to provide specific examples of problems in conceptualizing WOH. We propose that WOH be studied more often, especially by researchers in the natural and biomedical sciences, and that such studies include both women and men, where possible, and consider the complex relationships of gender and sex to the pathways involved. More interdisciplinary research would facilitate this process, since social researchers have tended to focus more on gender/sex issues. Our findings demonstrate that it is necessary to explore the implications of using sex routinely as an explanatory variable in occupational health research and to increase emphasis on the mechanisms involved in any sex or gender differences sought or found. From an equity perspective, it is also important to situate biological sex differences so as to prevent them from being used erroneously to justify job segregation or inequitable health promotion measures.

description: Controllers for autonomous systems that operate in safety-critical settings must account for stochastic disturbances. Such disturbances are often modelled as process noise, and common assumptions are that the underlying distributions are known and/or Gaussian. In practice, however, these assumptions may be unrealistic and can lead to poor approximations of the true noise distribution. We present a novel planning method that does not rely on any explicit representation of the noise distributions. In particular, we address the problem of computing a controller that provides probabilistic guarantees on safely reaching a target. First, we abstract the continuous system into a discrete-state model that captures noise by probabilistic transitions between states. As a key contribution, we adapt tools from the scenario approach to compute probably approximately correct (PAC) bounds on these transition probabilities, based on a finite number of samples of the noise. We capture these bounds in the transition probability intervals of a so-called interval Markov decision process (iMDP). This iMDP is robust against uncertainty in the transition probabilities, and the tightness of the probability intervals can be controlled through the number of samples. We use state-of-the-art verification techniques to provide guarantees on the iMDP, and compute a controller for which these guarantees carry over to the autonomous system. Realistic benchmarks show the practical applicability of our method, even when the iMDP has millions of states or transitions.

description: The matrix profile (MP) is a data structure computed from a time series which encodes the data required to locate motifs and discords, corresponding to recurring patterns and outliers respectively. When the time series contains noisy data then the conventional approach is to pre-filter it in order to remove noise but this cannot apply in unsupervised settings where patterns and outliers are not annotated. The resilience of the algorithm used to generate the MP when faced with noisy data remains unknown. We measure the similarities between the MP from original time series data with MPs generated from the same data with noisy data added under a range of parameter settings including adding duplicates and adding irrelevant data. We use three real world data sets drawn from diverse domains for these experiments Based on dissimilarities between the MPs, our results suggest that MP generation is resilient to a small amount of noise being introduced into the data but as the amount of noise increases this resilience disappears

description: The spin 1/2 entropy of electrons trapped in a quantum dot has previously been measured with great accuracy, but the protocol used for that measurement is valid only within a restrictive set of conditions. Here, we demonstrate a novel entropy measurement protocol that is universal for arbitrary mesoscopic circuits and apply this new approach to measure the entropy of a quantum dot hybridized with a reservoir, where Kondo correlations dominate spin physics. The experimental results match closely to numerical renormalization group (NRG) calculations for small and intermediate coupling. For the largest couplings investigated in this work, NRG predicts a suppression of spin entropy at the charge transition due to the formation of a Kondo singlet, but that suppression is not observed in the experiment.

description: Στόχος της συγκεκριμένης ερευνητικής εργασίας είναι η εύρεση και η καταγραφή των νέων τρόπων αναγνώρισης και ανάλυσης της κοινωνικής και δομικής πραγματικότητας στη σύγχρονη εποχή. Θεωρητική βάση αποτελεί η σκέψη των Gilles Deleuze και Felix Guattari, που κατά το τέλος του 20ου αιώνα επηρέασε πλήθος ερευνητών και αρχιτεκτόνων και αποτέλεσε το εύφορο έδαφος για την ανάπτυξη νέων θεωριών και την αναδιαμόρφωση παλαιοτέρων μέσω νεών θεωρητικών φίλτρων. Στην πρώτη ενότητα προσεγγίζεται η θεωρία του νεοπραγματισμού υπό την οπτική του John Rajchman, όπου χρησιμοποιώντας το διάγραμμα ως το βασικό αναλυτικό του εργαλείο κατάφερε να ορίσει ένα νέο θεωρητικό λεξιλόγιο, το οποίο εν συνεχεία χρησιμοποίησαν οι Ολλανδοί αρχιτέκτονες για να θέσουν με τη σειρά τους, τους αρχιτεκτονικούς όρους αστικής ανάλυσης και σχεδιασμού τους. Τα δομικά αποτελέσματα των νέων αυτών όρων αναλύονται στη συνέχεια, μέσω της καταγραφής χαρακτηριστικών αρχιτεκτονικών παραδειγμάτων που παρουσιάζουν σημεία επαφής με το θεωρητικό υπόβαθρο της αναλυτικής θεωρίας του Rajchman και που συνέβαλλαν στη διαμόρφωση της αισθητικής του ‘Δεύτερου Ολλανδικού Μοντερνισμού’. Στη δεύτερη ενότητα της εργασίας, παρουσιάζονται δύο παρακλάδια μίας σύγχρονης θεωρητικής προσέγγισης, η θεωρία των συναρμογών (Manuel DeLanda) και η αντικειμενοστραφής οντολογία (Graham Harman). Το χαρακτηριστικό που καθιστά τις νέες αυτές σκέψεις ως θεωρητικά ενδιαφέρουσες είναι η στροφή τους προς τον επαναπροσδιορισμό της σημαντικότητας του αντικειμένου ως το βασικό εργαλείο ανάγνωσης και επεξεργασίας της πραγματικότητας, καταργώντας μία από τις κλασσικότερες φιλοσοφικές σταθερές, την κυριαρχία του υποκειμένου -ανθρώπου έναντι του κόσμου στον οποίο δρα και υπάρχει. Τέλος, γίνεται μία προσπάθεια προσέγγισης του αντικατοπτρισμού των μεταουμανιστικών θεωριών στην αρχιτεκτονική σκέψη μέσα από την επίπεδη οντολογία, της οποίας τα θεωρητικά και αισθητικά χαρακτηριστικά εισάγει ο Tom Wiscombe, η αναγνώριση και καταγραφή των οποίων αποτελεί το τελευταίο μέρος της συγκεκριμένης εργασίας.

Communication--International cooperation

description: The Great War of 1914-1918 transformed the relationship of the United States to Europe, creating a raft of new opportunities for commerce, diplomacy, and public understanding. Among the public figures to find these possibilities inspiring was Walter S. Rogers, a liberal journalist dedicated to the cause of improving the quality of foreign reporting. Rogers was best known to the public in 1918 as the director of a New York City-based international news service that he operated for the Committee on Public Information, the government's official news agency. Rogers's expansive conception of the possibilities of the press would inform the position that he took as a delegate to an international communications conference that the victorious powers convened in Washington, DC, in October 1920. Attendance at this conference was limited to five countries: the United Kingdom, France, the United States, Italy, and Japan. Its original rationale was to resolve a number of issues left over from the Paris Peace Conference. Of these the most pressing was the legal status of German cables that the allies had cut, and in some instances, repurposed, during the war. Yet the conference soon acquired the much more open-ended rationale of drafting the charter for an entirely new international organization--a Universal Electrical Communications Union--that would create for the first time in world history a single forum for the regulation of every form of electrically mediated communications--telegraphy telephony, cable, and radio. No longer would cable and radio be regulated under different international conventions, as they had been in the past. The failure of the 1920 Washington conference reveals some of the limitations of liberal internationalism. These constraints become especially evident if one views the conference through Rogers's eyes, which it is possible to do, given the existence in the National Archives of several boxes of Rogers's official files. Little used by historians, these papers provide a window on the challenges that confronted US public figures like Rogers who had hoped in the aftermath of the Great War to expand the role of the United States in world affairs.

description: This work presents an experimental study of a nanosecond repetitively pulsed dielectric barrier discharge interacting with a transient laminar flame propagating in a channel of height near the quenching distance of the flame. The discharge and the flame are of comparable size, and the discharge is favoured at a location where it is coupled with the reaction zone and burned gas. The primary goal is to determine how the discharge evolves on the time scale of the flame passage, with the evolution driven by the changing gas state produced by the moving flame front. This work complements the large body of work investigating the effect of plasma to modify flame dynamics, by considering the other side of the interaction (how the discharge is modified by the flame). The hot gas produced by the combustion had a strong effect on the discharge, with the discharge preferentially forming in the region of hot combustion products. The per-pulse energy deposited by the discharge was measured and found to increase with the size of the discharge region and applied voltage. The pulse repetition frequency did not have a direct impact on the per-pulse energy, but did have an effect on the morphology and size of the discharge region. Two distinct discharge regimes were observed: uniform and filamentary (microdischarges). Higher pulse repetition frequencies and faster-cooling combustion products were more likely to transition to the filamentary regime, while lower frequencies and slower-cooling combustion products maintained a uniform regime for the entirety of the time the discharge was active. This regime transition was influenced by the ratio of the time scale of fluid motion to the pulse repetition rate. This work demonstrates the importance of considering how the discharge properties will change due to combustion processes in applications utilizing plasma assistance for transient combustion systems.

description: We study black hole solutions in Chern-Simons higher spin supergravity based on the superalgebra sl(3|2). These black hole solutions have a U(1) gauge field and a spin 2 hair in addition to the spin 3 hair. These additional fields correspond to the R-symmetry charges of the supergroup sl(3|2). Using the relation between the bulk field equations and the Ward identities of a CFT with N=2 super-W_3 symmetry, we identify the bulk charges and chemical potentials with those of the boundary CFT. From these identifications we see that a suitable set of variables to study this black hole is in terms of the charges present in three decoupled bosonic sub-algebras of the N=2 super-W_3 algebra. The entropy and the partition function of these R-charged black holes are then evaluated in terms of the charges of the bulk theory as well as in terms of its chemical potentials. We then compute the partition function in the dual CFT and find exact agreement with the bulk partition function.

description: We present higher order Discontinuous Galerkin discretizations schemes of two-phase flow model arising in the modelisation of subsurface flows in strongly heterogeneous porous media. The flow in the domain is immiscible and incompressible with no mass transfer between phases. We consider a fully implicit, locally conservative, higher order discretization on adaptively generated meshes. The implementation is based on the Open- Source PDE software framework DUNE.
