description: This paper reflects on questions of sexuality, gender, and desire by delving into the artistic practice of the photographer Wolfgang Tillmans, whose work seeks to transcend the idea of a binary, patriarchal society that is hetero- and cisnormative. In one of his installations, on display from 2004 to 2009 in the Panorama Bar of the club Berghain, two highly ambiguous camera-less Freischwimmer photographs were displayed next to a photograph of a human genital area. It is this interdependence of different image realities that, as a performative strategy in the process of reception, not only entails anticipatory and transformative potentialities, but also allows for a queer reading. Starting from queer art studies and its critique of identity and visibility politics, the overall aim of this paper is to find out to what extent the photo installation intervenes in normative discourses of sexuality, gender, and desire. In the subcultural context of the techno and rave club culture, Tillmans’ radically ambiguous installation becomes highly political, foregrounding a heterotopic playground, in which norms of visibility are negotiated in a way that eludes the hetero- and homonormative modes of representation. While emphasizing the inescapable dimension of context in both art production and its reception and interpretation, this paper argues that by aiming at a constant (re-)contextualization and (re-)combination Tillmans’ curatorial practice favors discontinuities rather than continuities of meaning. This leaves us with the structural ‘unsaturation’ of contexts, and thus the impossibility of final determination.

description: Στα τέλη του 19ου αιώνα Αυστριακοί χαρτογράφοι κατασκεύασαν τη σειρά χαρτών Generalkarte, που αναφέρεται στην περιοχή των Βαλκανίων, και ειδικότερα στην Βορείο Ελλάδα. Αυτό ήταν ένα γεγονός που επηρέασε τη μετέπειτα πορεία της χαρτογραφικής ιστορίας της Ελλάδας. Οι χάρτες αυτοί αποτέλεσαν τη βάση για την κατασκευή των ελληνικών παράγωγων χαρτών της δεκαετίας του ‘10 και γενικότερα ήταν το εργαλείο πολιτικού και στρατιωτικού σχεδιασμού μέχρι τη δεκαετία του ’50, χάρη στην ακρίβεια αποτύπωσης του χώρου και την πληθώρα πληροφοριών που περιείχαν. Στην εργασία αυτή αναλύεται η δομή και η σύνθεση των χαρτών της Generalkarte και των ελληνικών της παράγωγων στην περιοχή του Νομού Κιλκίς και γίνεται η σύγκρισή τους με το σύγχρονο χαρτογραφικό υπόβαθρο. Επίσης γίνεται μελέτη των ονομασιών και της θέσης των τοπωνυμίων της περιοχής, ώστε να διαπιστωθεί η ακρίβεια κατασκευής αυτών των χαρτών.
description: In the late 19th century Austrian cartographers built a series of maps Generalkarte, referred to in the Balkans, particularly in Northern Greece. This was an event that affected the outcome of the cartographic history of Greece. These maps formed the basis for the construction of the Greek derivative maps of early '10 and was generally the tool of political and military planning until the '50s, thanks to accurate snapshot of the area and the wealth of information they contain. In this paper we analyze the structure and composition of maps of Generalkarte and Greek derivatives in the region of Kilkis and the comparison with modern cartographic background. It also is studying the names and location of place names in the region to determine the precise construction of these maps.

description: In this paper we give an asymptotic formula for a matrix integral which plays a crucial role in the approach of Diaconis et al. to random matrix eigenvalues. The choice of parameter for the asymptotic analysis is motivated by an invariant theoretic interpretation of this type of integral. For arbitrary regular irreducible representations of arbitrary connected semisimple compact Lie groups, we obtain an asymptotic formula for the trace of certain operators on the space of tensor invariants, thus extending a result of Biane on the dimension of these spaces.

description: We present dynamical models of the star-forming galaxy NGC 5474 based on $N$-body hydrodynamical numerical simulations. We investigate the possible origin of the compact round stellar structure, generally interpreted as the bulge of the galaxy, but unusually off-set by $\simeq1$ kpc in projection from the visual and the kinematic centres of both the star and the gas discs. We argue that it is very unlikely that the putative bulge is in a co-planar orbit in the disc plane, showing that such a configuration would be hardly compatible with its smooth and regular spatial distribution, and, in case its mass is above $10^8\,M_{\odot}$, also with the regular HI velocity field of NGC 5474. Instead, if the putative bulge is in fact an early-type satellite galaxy orbiting around NGC 5474, not only the off-set can be easily produced by projection effects, but our simulations suggest that the gravitational interaction between the two systems can explain also the warped HI distribution of NGC 5474 and the formation of its loose spiral arms. As a by-product of the simulations, we find that the peculiar over-density of old stars detected in the south-west region of NGC 5474 may be explained with the interaction between NGC 5474 and a smaller stellar system, unrelated to the putative bulge, accreted in the disc plane.

Self-heating and isothermal characterization of heterojunction bipolar transistors
Creators: name: Kleckner, Todd Christopher
Publisher: name: University of British Columbia
Year: 2009

description: Self-heating, the process by which power dissipation causes a rise in the operating temperature of the device, causes significant changes in the operation of bipolar transistors and can compromise the accuracy of device models if the operating environment of the device is not identical to the one in which it was characterized. As conventional methods utilized to construct device models are based in part upon measurements of device performance in which the static power dissipation results in an elevated device temperature, the extracted model contains information pertaining to the thermal environment in which it was characterized. This hidden temperature dependence is often ignored, and results in erroneous parameter extraction. Extending a technique developed by workers at Hewlett-Packard, a pulsed bias measurement system has been developed which addresses the need for temperature-independent device characterization. This system can be used to measure the isothermal collector characteristics at constant base-emitter voltage, and the isothermal Gummel plot of collector current. The resulting data can be used to extend the region of model validity by de-embedding the thermal effects from the inherent isothermal electrical response of the device. The system can also be used to determine the values of the thermal resistance and capacitance, macroscopic thermal parameters that can be used with device model thermal subcircuits. Using this measurement technique, the first experimental studies of thermal parameter scaling in deep-trench Si/SiGe and non-trench-isolated AlGaAs/GaAs heterojunction bipolar transistors has been performed. Scaling coefficients were determined for the dependence of thermal resistance and capacitance on emitter area. Comparison of measured thermal resistances to model predictions show substantial deviations for small devices and for large devices. Results for small devices suggest the interconnect metallization plays a significant role, and those for large devices show that electrothermal feedback is important and must be accounted for. For each of the two technologies studied, measured thermal capacitances vary linearly with the square root of the emitter area and depend only weakly on the emitter geometry. The result is a simple thermal capacitance scaling law which allows estimates for unknown structures in a given technology from a single measurement.

description: Im Rahmen der vorliegenden Arbeit wurde die Rolle von Vanadium bei der Partialoxidation von Methacrolein zu Methacrylsäure an Heteropolysäuren mittels In-situ-Raman-Spektroskopie untersucht. Hierzu wurden eigens präparierte Heteropolysäuren vom Keggin-Typ mit verschiedenen Zusammensetzungen als Modellsysteme hergestellt und zusammen mit technisch-relevanten Industrie-HPA-Katalysatoren verglichen. Für die Untersuchungen musste zunächst eine Versuchsapparatur aufgebaut werden, an welcher sich unter prozessrelevanten Bedingungen im Labormaßstab die HPA-Katalysatoren in einer selbst-entwickelten In-situ-Messzelle mit einem konfokalen Raman-Mikroskop untersuchen ließen. Eine mögliche Korrelation der katalytischen Aktivität (anhand der online GC-Produktgasanalysen) mit den spektroskopischen Beobachtungen aus den In-situ-Raman-Spektren stand hierbei im Vordergrund. Nach der Anlagenvalidierung und der Reproduzierung von literaturbekannten Beobachtungen konnten anhand von Variationen der Feedgas-Zusammensetzungen Systematiken bzgl. der Vanadylspezies zugeordneten Raman-Bande bei ~1034 cm-1 beobachtet werden. Auf Basis dieser Beobachtungen wurde u.a. auch die gezielte Anreicherung von Vanadylspezies über eine Imprägnierungsmethodik an verschiedenen Heteropolysäurekatalysatoren realisiert und die katalytische Performance solcher modifizierten Systeme untersucht. Hierbei konnten für HPA-Katalysatoren bei denen, bezogen auf die Ausgangsstöchiometrie Cs2H2PVMo11O40, zusätzliche 0.5 Vanadium-Äquivalente durch die Vanadylimprägnierung eingebracht wurden, eine signifikant gesteigerte katalytische Performance reproduzierbar beobachtet werden. Über temperaturprogrammierte Reaktionen konnten im Falle der VO2+-modifizierten Systeme durch sogenannte Stresstests (zyklisch ablaufende Temperatur-/Feedgas-Profile), neben der gesteigerten katalytischen Aktivität, auch Anhaltspunkte für eine verbesserte Langzeitstabilität von HPA-Katalysatoren beobachtet werden.
Feshbach resonances in ultracold atomic and molecular collisions: threshold behaviour and suppression of poles in scattering lengths

description: In the absence of inelastic scattering, Feshbach resonances produce poles in scattering lengths and very large peaks in elastic cross sections. However, inelastic scattering removes the poles. Whenever the resonant state is coupled comparably to the elastic and inelastic channels, the scattering length exhibits only a small oscillation and peaks in cross sections are dramatically suppressed. A resonant scattering length is defined to characterize the amplitude of the oscillation, and is shown to be small for many collisions of ultracold molecules. The results suggest that cross sections for ultracold molecular inelastic collisions are much less sensitive to details of the potential than has been believed.
description: 10 pages, 2 figures. Version 4 has slightly revised content to reflect the realisation that the resonant scattering length a_res can be complex, which will sometimes produce a reduction in inealastic scattering near a resonance

description: Within a quark combination model, we study systematically the yields and rapidity spectra of various hadrons in central Au+Au collisions at $\sqrt{s_{NN}}= 200$ GeV. We find that considering the difference in rapidity between net-quarks and newborn quarks, the data of multiplicities, rapidity distributions for $π^{\pm}$, $K^{\pm}$, $p(\bar{p})$ and, in particular the ratios of charged antihadron to hadron as a function of rapidity, can be well described. The effect of net-quarks on various hadrons is analysed, and the rapidity distributions for $K^{0}_{s}$, $Λ(\barΛ)$, $Σ^{+}(\barΣ^{_-})$, $\mathrm{Ξ^{-}}$ ($\mathrm{\barΞ^{_+}}$) and $\mathrm{Ω^{-}}(\mathrm{\barΩ}^{_+})$ are predicted. We discuss the rapidity distribution of net-baryon, and find that it reflects exactly the energy loss of colliding nuclei.

description: The density matrix renormalization group (DMRG) has been extended to study quantum phase transitions on random graphs of fixed connectivity. As a relevant example, we have analysed the random Ising model in a transverse field. If the couplings are random, the number of retained states remains reasonably low even for large sizes. The resulting quantum spin-glass transition has been traced down for a few disorder realizations, through the careful measurement of selected observables: spatial correlations, entanglement entropy, energy gap and spin-glass susceptibility, among others.

title: Snacks and nutrition during the complementary feeding period: a cross-sectional study among children 12-23 months of age in Kathmandu Valley, Nepal
Creators: name: Pries, AM
Publisher: name: London School of Hygiene & Tropical Medicine

description: Availability and consumption of processed foods has grown rapidly in low- and middle-income countries (LMIC), among both adults and children. While snacks provide energy during the nutritionally vital complementary feeding period, consumption of unhealthy snack foods and beverages (USFB), typically energy-dense and nutrient-poor, is concerning given young children’s high nutritional requirements and limited gastric capacity. However, there is limited information on the contribution of such foods to dietary intakes and the potential nutritional consequences among young children in LMIC. This thesis describes a cross-sectional study in Kathmandu Valley, Nepal that assessed dietary intakes of a representative sample of 12-23-month-old children (n=745) and examined the association between high consumption of USFB and nutritional status. We found that USFB contributed on average 5.2% of total energy intakes (% TEI) from non-breastmilk foods among the lowest tercile of USFB consumers and 46.9% TEI among the highest tercile. Nearly 9/10 of USFB were commercial products, with biscuits (10.8%), candy/chocolate (3.5%), and savoury snacks (3.4%) providing the largest % TEI. Compared to low USFB consumers, high USFB consumers had lower dietary intakes of 12 nutrients and were at greater risk of inadequate intakes for 8 nutrients. In a model adjusted for other covariates of undernutrition, mean length-for-age (LAZ) was 0.29 standard deviations lower among high USFB consumers than low consumers (p=0.003). No associations were found between high USFB consumption and stunting prevalence or iron status. The prevalence of overweight/obesity was low. Findings from this study indicate that high USFB consumption among young children is associated with increased risk of inadequate micronutrient intakes, which may contribute to poor growth outcomes. In LMIC contexts where the nutrient density of complementary feeding diets is low, addressing the increased availability of inexpensive, packaged products in LMIC food systems should be a priority for policies and programs aiming to safeguard child nutrition.

description: equalAIs believes in "Empowering People & Thwarting Machines". The equalAIs project is aimed at spurring more public discourse around how individuals' data and images are used in face detection and recognition systems and investigating how tools can allow individuals to express or enforce their level of consent to face detection while providing them with the means to avoid face detection. To that end, our work has multiple components, from a FOIA request for information about the federal government’s use of facial detection to an open sourced technical prototype for modifying images so that facial detection systems cannot identify faces in them. We propose a tool that provides three means of communicating a lack of consent to face detection systems while enabling images to evade face detection: (1) an adversarial perturbation of the image to prevent face detection systems from identifying a face; (2) a steganographic message encoding that explicitly states that a user does not consent to face detection; and (3) a visible watermark communicating that the user does not consent to face detection. We demonstrate our tool's level of effectiveness at reducing the detection rates of several common face detection libraries and commercially available face detection APIs including the dlib face detector, OpenCV Haar cascades face detector, Google Cloud Vision API, Microsoft Cognitive Face API, Clarifai face detection, and Watson Vision API. The equalAIs webtool is available at https://equalais.media.mit.edu/. equalAIs is a project that was developed out of the 2018 Assembly Program at the Berkman Klein Center for Internet & Society at Harvard University and the MIT Media Lab.

For each target galaxy we obtained high-resolution spectroscopy of the Halpha and [NII]lambda6583 emission lines at three slit positions, to measure the central ionized-gas kinematics. ACS images in three different filters (F435W, F625W, and FR656N) have been used to determine the optical depth of the dust, stellar mass distribution near the nucleus, and intensity map. We present supermassive black hole (SBH) mass estimates for two galaxies which show regular rotation curves and strong central velocity gradients, and an upper limit on the SBH mass of the third one. For the SBHs of Abell 1836-BCG and Abell 3565-BCG, we derived M_bh=4.8(-0.7,+0.8)10**9 M_sun and M_bh=1.3(-0.4,+0.3)10**9 M_sun at 1 sigma confidence level, respectively. For the SBH of Abell 2052-BCG, we found M_bh < 7.3 10**9 M_sun.

description: The importance of fluid-elastic forces in tube bundle vibrations can hardly be over-emphasized, in view of their damaging potential. In the last decades, advanced models for representing fluid-elastic coupling have therefore been developed by the community of the domain. Those models are nowadays embedded in the methodologies that are used on a regular basis by both steam generators providers and operators, in order to prevent the risk of a tube failure with adequate safety margins. From an R&D point of view however, the need still remains for more advanced models of fluid-elastic coupling, in order to fully decipher the physics underlying the observed phenomena. As a consequence, new experimental flow-coupling coefficients are also required to specifically feed and validate those more sophisticated models. Recent experiments performed at CEA-Saclay suggest that the fluid stiffness and damping coefficients depend on further dimensionless parameters beyond the reduced velocity. In this work, the problem of data reduction is first revisited, in the light of dimensional analysis. For single-phase flows, it is underlined that the flow-coupling coefficients depend at least on two dimensionless parameters, namely the Reynolds number $Re$ and the Stokes number $Sk$. Therefore, reducing the experimental data in terms of the compound dimensionless quantity $V_r=Re/Sk$ necessarily leads to impoverish results, hence the data dispersion. In a second step, experimental data are presented using the dimensionless numbers $Re$ and $Sk$. We report experiments, for a 3x5 square tube bundle subjected to water transverse flow. The bundle is rigid, except for the central tube which is mounted on a flexible suspension allowing for translation motions in the lift direction.

description: We extend to convenient finite quotients of a noetherian Lambda-module the classical result of K. Iwasawa giving the asymptotic expression of the l-part of the number of ideal class groups in Zl-extensions of number fields. Then, in the arithmetic context, we compute the three characters associated by this way to the l-groups of T-infinitesimal S-classes in the cyclotomic tower and relate them to the classical invariants and the decomposition characters associated to the finite sets of places S and T. A main tool in this study is the so-called Spiegelungssatz of Georges Gras, which exchanges (wild or tame) ramification and decomposition. The main results of this arithmetical part extend those we obtained with Christian Maire in a previous article. The most intricate study of the wild contribution of the sets S and T involves a generalization of a classical result of R. Greenberg on the genus theory of cyclotomic towers.
Survival analysis ​of pediatric patients with brain tumors using a machine learning method: decision tree analysis by recursive partitioning

description: Studies with censored data are numerous in the medical field. The regression model with Cox proportional hazards and its extensions are frequently used. These parametric and semiparametric methods allow simple interpretation of the effects of covariates and inference. Yet these models force the choice of specific relationships between the covariates and the response, which are specified by the analyst. Decision trees and forests are popular non-parametric alternatives. They can detect ("learn") automatically some non-prespecified relations. The decision tree can be defined as a structure that can be used to subdivide a set of records successively into smaller sets, applying a simple sequence of decision rules. After each successive division, the resulting subset members become increasingly similar.

We used the data from two research projects in progress, collected by the retrospective analysis of medical records of patients 0-18 years diagnosed with a brain tumor between 2000 and 2010. Semi-supervised decision trees were constructed, where classes were previously chosen but they were grouped automatically. We used the method of construction of survival trees proposed by Breiman et al (CART), with the help of rpart package of the statistical programming language R. The primary outcome evaluated was overall survival (time between diagnosis and censorship or event: death from any cause). We used the pruning method based on complexity parameter, in order to remove the less important ramifications and give a nested subassembly, forming a shorter and more robust tree.

We included 227 patients. A survival tree was constructed with 21 nodes (branches), 11 terminals (leaves), including as variables topography, distance from the treatment center (≥ 391km) , radiotherapy (RT), histology (embryonal tumors vs. others), geographical region. After trimming, the final tree was obtained with 9 nodes, 5 terminals. Discrete patient subsets (leaves) selected were (order of highest to lowest survival): low-grade gliomas (22% of the total number (N); hazards ratio (HR) = 0.24), patients with other histologies who received RT (35% of N, HR = 0.73), patients with other histologies that did not receive RT and had a complete surgical resection (16% of N, HR = 1.1), patients that had a partial resection (11% of N, HR = 2.9) and, finally, pontine tumors (15% of N, HR = 2.9).

The machine learning approach by recursive partitioning of survival trees is an attractive complementary method to traditional survival analysis by regression. Through this study, we confirmed some previous observations and have found new prognostic factors for survival in children with brain tumors. Among the findings, we stress the impact of grouping the pontine tumors in a separate category because of their high frequency and worst prognosis in children.

description: This
 deliverable supports the activities related to the Task 5.6 and describes the practical implementation of the pathways of well being and of the interfaces that supports the different pathways. In particular, the NESTORE Coach app is presented as demonstrator of T5.6 and of the NESTORE Coaching system.
 In this task, wellbeing pathways are designed to guide the user towards the personal goals, as defined in Task 5.1. This task also implements the NESTORE app th at will support the coach intervention in the selected pathway. In particular, the Coach App provides a detailed visualization of the user progress in the different dimensions to empower the user through self monitoring as well as a system for self reporti ng information that cannot be automatically measured through the wearable and environmental sensors or through the analysis of the interaction with the coach.
 In the first part, we describe:
 - which design strategy we have chosen to follow for this project;
 - the identification of the users of NESTORE with their characteristics;
 - the NESTORE Identity definition and design, which we adapted to future users to be recognizable and valuable. We defined colours, fonts and tone of voice in order to succeed in NESTORE goals.
 After this analysis, strong motivations led us to design clear, dynamic and intuitive User Experience to entertain. We explain our choices in the second section.
 The third part describes the Wellbeing Pathways that were thought to be the main focu s of users’ activity.
 Pathways are divided into four categories: physical domain, nutritive domain, cognitive domain and social domain.
 Every domain has different goals to reach and a lot of activities, exercises or games that the user can make to improve his life habits.

description: Flux-dominated solar dynamo models, which have demonstrated to be quite successful in reproducing most of the observed features of the large scale solar magnetic cycle, generally produce an inappropriate latitudinal distribution of the toroidal magnetic fields, showing fields of large magnitude in polar regions where the radial shear has a maximum amplitude. Employing a kinematic solar dynamo model, we here explore the contribution of both the radial and the latitudinal shear in the generation of the toroidal magnetic fields by varying the shape and the thickness of the solar tachocline. We also explore the effects of the diffusivity profile of the convective zone. We find that the latitudinal component is always dominant over the radial component at producing toroidal field amplification. These results are very sensitive to the adopted diffusivity profile, specially in the inner convection zone. A diagram of the toroidal field at a latitude of 60 degrees versus the diffusivity at the convection layer for different values of the tachocline width has revealed that these fields are mainly eliminated for tachoclines with width d_1>0.08 Ro, for a restric range of diffusivites; or for d_1<0.02 and almost any value of eta_c in the appropriate solar range. For intermediate values of d_1=0.04Ro-0.06Ro, strong toroidal fields should survive at high latitudes in the butterfly diagram and those values are therefore not suitable.

description: We made a first attempt to associate a probabilistic description of stochastic processes like birth-death processes with spacetime geometry in the Schwarzschild metrics on distance scales from the macro- to the micro-domains. We idealize an ergodic system in which system states communicate through a curved path composed of transition arrows where each arrow corresponds to a positive, analogous birth or death rate.

description: Στην παρούσα εργασία εξετάζεται η εξέλιξη της απεικόνισης της μορφής της Νίκης στη γλυπτική και νομισματική από το 31 π.Χ. έως το 13ο αιώνα μ.Χ. και η μετατροπή της σε άγγελο και τελικά στον αρχάγγελο Μιχαήλ. Χρονική αφετηρία στάθηκε η ναυμαχία του Ακτίου, επειδή τότε ο Οκταβιανός Αύγουστος παγίωσε τα χαρακτηριστικά της Νίκης και τα διακριτικά σύμβολα που αυτή κρατούσε και ανέδειξε σε σύμβολο τη μορφή της θεάς. Η Νίκη ήταν ένα από τα αγαπημένα εικονογραφικά θέματα, επειδή συμβόλιζε την νίκη και τον θρίαμβο. Οι τύποι της Νίκης που μελετήθηκαν ήταν τέσσερις: α) η Νίκη πάνω σε σφαίρα, β) η Νίκη ως ηνίοχος, γ) η Νίκη που στεφανώνει τον αυτοκράτορα και δ) η Νίκη με ασπίδα. Μετά εξετάσθηκε η εικονογραφία του αγγέλου και τέλος περιλήφθηκαν οι κατάλογοι των νομισμάτων, των γλυπτών και των επιγραφών των νομισμάτων. Μελετήθηκαν επίσης και οι συμβολισμοί που σχετίζονται με τη χρήση της Νίκης στην εικονογραφία και οι λόγοι για τους οποίους τα νομισματοκοπεία επέμεναν να επιλέγουν το συγκεκριμένο θέμα.
description: The topic of this essay refers to the depiction of the goddess Victory on roman and byzantine sculpture and coins from 31 B.C. to 13n century A.C. and her evolution to angel and finally to archangel Michael. The beginning was the battle in Actium, when Octavian Augustus settled the characteristics of Victory, the symbols she held and regarded the goddess as a symbol. Victory symbolized the victory and was always shown among the winners emperors. Four types of Victory were studied: a) Victory on a globe, b) Victory with clipeus virtutis, c) Victory who crowns the emperor and d) Victory as a charioteer. Then it was examined the iconography of angel and finally were included the catalogues of coins, sculpture and the graffiti of coins.

description: MUSE-based emission-line maps of the spiral galaxy NGC 4030 reveal the existence of unresolved sources with forbidden line emission enhanced with respect to those seen in its own HII regions. This study reports our efforts to detect and isolate these objects and identify their nature. Candidates are first detected as unresolved sources on an image of the second principal component of the Hb, [OIII]5007, Ha, [NII]6584, [SII]6716, 6731 emission-line data cube, where they stand out clearly against both the dominant HII region population and the widespread diffuse emission. The intrinsic emission is then extracted accounting for the highly inhomogeneous emission-line "background" throughout the field of view. Collisional to recombination line ratios like [SII]/Ha, [NII]/Ha, and [OI]/Ha tend to increase when the background emission is corrected for. We find that many (but not all) sources detected with the principal component analysis have properties compatible with supernova remnants (SNRs). Applying a combined [SII]/Ha and [NII]/Ha classification criterion leads to a list of 59 sources with SNR-like emission lines. Many of them exhibit conspicuous spectral signatures of SNRs around 7300 Angs, and a stacking analysis shows that these features are also present, except weaker, in other cases. At nearly 30 Mpc, these are the most distant SNRs detected by optical means to date. We further report the serendipitous discovery of a luminous (M_V ~ -12.5), blue, and variable source, possibly associated with a supernova impostor.

description: Under the current data paradigm, third parties often capture, analyze, and make use of an individual’s data without that individual’s knowledge or consent. The uses of this data are often opaque, and even when an individual signs a “Terms of Service Agreement” it is questionable whether they truly provide informed consent. With the EU’s General Data Protection Regulation (GDPR), we’re seeing momentum to provide individuals with greater data privacy protection. As part of the Assembly on artificial intelligence and governance -- a joint project between the Berkman Klein Center at Harvard University and the MIT Media Lab -- we are creating technical and policy mechanisms that empower individuals to thwart third parties from successfully analyzing their data and to communicate that they do not want their data to be used in ways that they did not consent to. We are building a tool that directly embeds “Do Not Track”-like signature in images while simultaneously duping image classification systems.

description: The Safety Management System (SMS) is one of six management systems mandated by Section 1 034 of the 1991 lntermodal Surface Transportation Efficiency Act (ISTEA). The overall goal of a SMS is to reduce the number and severity of traffic crashes. lt is to be comprehensive in that it incorporates all public roads and all contributing factors associated with the driver, the vehicle, and the roadway. The objective of this study was to develop a procedure to implement a SMS for Kentucky. A recommended process is described. Agencies and organizations were identified which have a role or interest in traffic safety. Contacts were made with these agencies and organizations, and their activities in the area of traffic safety were described. The purpose of these contacts was to establish a safety inventory for the state.  The composition of a Safety Management Steering Committee was recommended along with subcommittees in the general areas of roadway, human, and vehicle factors, as well as information services and evaluation. Data needs to be used in the implementation of the SMS were identified. An evaluation process was described. A schedule for the implementation of the SMS was recommended.
