description: The optically variable source SDSS J124602.54+011318.8 first appears in Sloan Digital Sky Survey (SDSS) data as a bright point source with nonstellar colors. Subsequent SDSS imaging and spectroscopy showed that the point source declined or disappeared, revealing an underlying host galaxy at redshift 0.385. Based on these properties, the source was suggested to be a candidate ``orphan afterglow'': a moderately beamed optical transient, associated with a gamma-ray burst (GRB) whose highly beamed radiation cone does not include our line of sight. We present new imaging and spectroscopic observations of this source. When combined with a careful re-analysis of archival optical and radio data, the observations prove that SDSS J124602.54+011318.8 is in fact an unusual radio-loud AGN, probably in the BL Lac class. The object displays strong photometric variability on time scales of weeks to years, including several bright flares, similar to the one initially reported. The SDSS observations are therefore almost certainly not related to a GRB. The optical spectrum of this object dramatically changes in correlation with its optical brightness. At the bright phase, weak, narrow oxygen emission lines and probably a broader H$α$ line are superposed on a blue continuum. As the flux decreases, the spectrum becomes dominated by the host galaxy light, with emerging stellar absorption lines, while both the narrow and broad emission lines have larger equivalent widths. We briefly discuss the implications of this discovery on the study of AGNs and other optically variable or transient phenomena.

Spontaneously Broken Spacetime Symmetries and Fermi Liquid Theory

Subjects: subject: 20399 Classical Physics not elsewhere classified

description: I discuss the implications of spontaneously broken spacetime symmetries in context of Condensed Matter Physics (CMP) and High Energy Physics (HEP). Starting
with a minimal set of assumptions, a lot can be learned about complicated many body quantum systems using the ideas from Coset Construction and Eff ective Field theories (EFT). The fact that any symmetry of the full theory must be realized, linearly or non-linearly, in the infra red (IR) limit puts strong constraints on the low energy dynamics of any EFT. In this work, I have mainly focused on the Fermi
liquid theory (FLT), which in some sense is the simplest CMP system. Even though the phenomenology of FLT has been worked out extensively, its analysis from the
point of view of spacetime symmetry breaking has shed some new light on the theory and led to the development of a novel idea the so-called Dynamical Inverse Higgs Mechanism, which is a new way of non-linear realization of broken spacetime symmetries. This technique is developed in this work in great detail. I also worked on a diff erent, yet more intuitive method of understanding broken spacetime symmetries by using the spacetime symmetry algebra. This is related to a well known concept in EFTs, called the Reparametrization Invariance (RPI). I work out several examples of the constraints that arise in HEP EFTs from RPI and how they can also be derived from the symmetry algebra. Lastly in the appendix, I also provide some detailed calculations related to the main body of my thesis and
a few other applications of Coset Construction besides Fermi liquids.

description: In this work we study kinklike structures, which are localized solutions that appear in models described by real scalar fields. The model to be considered is characterized by two real scalar fields and includes a function of one of the two fields that modifies the kinematics associated to the other field. The investigation brings to light a first order framework that minimizes the energy of the solutions by introducing an auxiliary function that directly contributes to describe the system. We explore an interesting route, in which one field acts independently, entrapping the other field, inducing important modifications in the profile of the localized structure. The procedure may make the solution to spring up as a kinklike configuration with internal structure, engendering the important feature that also appears directly connected with issues of current interest at the nanometric scale, in particular in the electronic transport in molecules in the presence of vibrational degrees of freedom.

description: Prompted by some inconsistencies in the photometry of the VISTA Variables in the Vía Láctea (VVV) survey, we conduct a revision of the standard calibration procedure of VISTA data in the $J$, $H$, and $K_S$ passbands. Two independent sources of bias in the photometric zero-points are identified: First, high sky backgrounds severely affect the $H$-band measurements, but this can mostly be minimized by strict data vetting. Secondly, during the zero-point calibration, stars serving as standards are taken from the 2MASS catalog, which can suffer from high degrees of blending in regions of high stellar density, affecting both the absolute photometric calibration, as well as the scatter of repeated observations. The former affects studies that rely on an absolute magnitude scale, while the latter can also affect the shapes and amount of scatter in the VVV light curves, thus potentially hampering their proper classification. We show that these errors can be effectively eliminated by relatively simple modifications of the standard calibration procedure, and demonstrate the effect of the recalibration on the VVV survey's data quality. We give recommendations for future improvements of the pipeline calibration of VISTA photometry, while also providing preliminary corrections to the VVV $JHK_\mathrm{S}$ observations as a temporary measure.

description: We use an analytic approach to study the susceptibility of the Planck Low Frequency Instrument radiometers to various systematic effects. We examine the effects of fluctuations in amplifier gain, in amplifier noise temperature and in the reference load temperature. We also study the effect of imperfect gain modulation, non-ideal matching of radiometer parameters, imperfect isolation in the two legs of the radiometer and back-end 1/f noise. We find that with proper gain modulation 1/f gain fluctuations are suppressed, leaving fluctuations in amplifier noise temperature as the main source of 1/f noise. We estimate that with a gain modulation factor within +- 1% of its ideal value the overall 1/f knee frequency will be relatively small (< 0.1 Hz).

description: Two-photon absorption (TPA) spectra of push-pull chromophores are described in terms of a two-state model accounting for electron-vibration coupling. Vibrations have two main effects in TPA spectra. The most obvious one is the appearance of a vibrational structure in the spectrum; in this respect we find large Herzberg-Teller contributions. The second effect was not recognized so far: vibrational states contribute a new channel to TPA process, that shows up with a blue-shift and a distortion of the spectrum. Vibrational-channel contributions to other NLO responses are shortly discussed.

description: Neural machine translation (NMT) has achieved new state-of-the-art performance in translating ambiguous words. However, it is still unclear which component dominates the process of disambiguation. In this paper, we explore the ability of NMT encoders and decoders to disambiguate word senses by evaluating hidden states and investigating the distributions of self-attention. We train a classifier to predict whether a translation is correct given the representation of an ambiguous noun. We find that encoder hidden states outperform word embeddings significantly which indicates that encoders adequately encode relevant information for disambiguation into hidden states. Decoders could provide further relevant information for disambiguation. Moreover, the attention weights and attention entropy show that self-attention can detect ambiguous nouns and distribute more attention to the context. Note that this is a revised version. The content related to decoder hidden states has been updated.

description: Magnetic skyrmions are topological magnetic spin structures exhibiting particle-like behaviour. They are of strong interest from a fundamental viewpoint and for application, where they have potential to act as information carriers in future low-power computing technologies. Importantly, skyrmions have high physical stability because of topological protection. However, they have potential to deform according to their local energy environment. Here we demonstrate that, in regions of high exchange energy density, skyrmions may exhibit such extreme deformation that spontaneous merging with nearest neighbours or spawning new skyrmions is favoured to attain a lower energy state. Using transmission electron microscopy and a high-speed imaging detector, we observe dynamics involving distinct configurational states, in which transitions are accompanied by spontaneous creation or annihilation of skyrmions. These observations raise important questions regarding the limits of skyrmion stability and topological charge conservation, while also suggesting a means of control of skyrmion creation and annihilation.

We explain a method to avoid the Goldstone pole contamination in the computation of renormalization constants for (delta I=3/2) operators. Finally we show some preliminary results for the matrix elements of (delta I=1/2) operators. Our quenched simulation is done at beta=6.0, with Wilson fermions, on a (24^3 X 64) lattice.

description: We report on $BVI$ CCD photometry of a field centered on the region of the intermediate-age open cluster NGC 2112 down to V=21. Due to the smaller field coverage, we are able to limit the effect of field star contamination which hampered in the past precise determinations of the cluster age and distance. This way, we provide updated estimates of NGC 2112 fundamental parameters. Having extended the photometry to the $I$ pass-band, we are able to construct a colour-colour diagram, from which we infer a reddening $E_{B-V}= 0.63\pm0.14$ mag. The comparison of the Colour-Magnitude Diagram (CMD) with theoretical isochrones leads to a distance of $850 \pm 100$ pc, and an age of $2.0 \pm 0.3$ Gyr. While the distance is in agreement with previous determinations, the age turns out to be much better constrained and significantly lower than previous estimates.

description: We study axion strings of hyperlight axions coupled to photons. Hyperlight axions -- axions lighter than Hubble at recombination -- are a generic prediction of the string axiverse. These axions strings produce a distinct quantized polarization rotation of CMB photons which is $\mathcal{O}(α_{\rm em})$. As the CMB light passes many strings, this polarization rotation converts E-modes to B-modes and adds up like a random walk. Using numerical simulations we show that the expected size of the final result is well within the reach of current and future CMB experiments through the measurement of correlations of CMB B-modes with E- and T-modes. The quantized polarization rotation angle is topological in nature and can be seen as a geometric phase. Its value depends only on the anomaly coefficient and is independent of other details such as the axion decay constant. Measurement of the anomaly coefficient by measuring this rotation will provide information about the UV theory, such as the quantization of electric charge and the value of the fundamental unit of charge. The presence of axion strings in the universe relies only on a phase transition in the early universe after inflation, after which the string network rapidly approaches an attractor scaling solution. If there are additional stable topological objects such as domain walls, axions as heavy as $10^{-15}$ eV would be accessible. The existence of these strings could also be probed by measuring the relative polarization rotation angle between different images in gravitationally lensed quasar systems.

description: This paper proposes a new method for determining similarity and anomalies between time series, most practically effective in large collections of (likely related) time series, by measuring distances between structural breaks within such a collection. We introduce a class of \emph{semi-metric} distance measures, which we term \emph{MJ distances}. These semi-metrics provide an advantage over existing options such as the Hausdorff and Wasserstein metrics. We prove they have desirable properties, including better sensitivity to outliers, while experiments on simulated data demonstrate that they uncover similarity within collections of time series more effectively. Semi-metrics carry a potential disadvantage: without the triangle inequality, they may not satisfy a "transitivity property of closeness." We analyse this failure with proof and introduce an computational method to investigate, in which we demonstrate that our semi-metrics violate transitivity infrequently and mildly. Finally, we apply our methods to cryptocurrency and measles data, introducing a judicious application of eigenvalue analysis.

description: In this paper, we present an end-to-end future-prediction model that focuses on pedestrian safety. Specifically, our model uses previous video frames, recorded from the perspective of the vehicle, to predict if a pedestrian will cross in front of the vehicle. The long term goal of this work is to design a fully autonomous system that acts and reacts as a defensive human driver would --- predicting future events and reacting to mitigate risk. We focus on pedestrian-vehicle interactions because of the high risk of harm to the pedestrian if their actions are miss-predicted. Our end-to-end model consists of two stages: the first stage is an encoder/decoder network that learns to predict future video frames. The second stage is a deep spatio-temporal network that utilizes the predicted frames of the first stage to predict the pedestrian's future action. Our system achieves state-of-the-art accuracy on pedestrian behavior prediction and future frames prediction on the Joint Attention for Autonomous Driving (JAAD) dataset.

description: We have used the Path Integral Monte Carlo method to simulate a monolayer of molecular hydrogen on graphite above 1/3 submonolayer coverage. We find that at low temperature and as the coverage increases the system undergoes a series of transformations starting from the $\sqrt{3} \times \sqrt{3}$ commensurate solid near 1/3 coverage. First, a phase is formed which is characterized by a uniaxially compressed incommensurate solid with additional mass density modulations along the same direction which can be viewed as an ordered domain-wall solid with a characteristic domain-wall distance which depends on the surface coverage. At low temperature and higher coverage there is a transition to an incommensurate solid which is rotated relative to the substrate commensurate lattice. As a function of temperature the domain-wall ordering first melts into a fluid of domain-walls and at higher temperature the solid melts into a uniform fluid. Regardless of the large amplitude of quantum fluctuations, these phase transitions are analogous to those in classical monolayer films. Our calculated values for the surface coverage and temperature where these transitions occur, the calculated structure factors and specific heat are in general agreement with the available experimental results with no adjustable parameteters.

description: A linearly-polarized aperture coupled patch antenna design is characterized by using MATLAB software. The aperture coupled patch antenna microstrip feedline, substrates, ground plane slot, and patch dimensions are varied to determine effects on antenna performance which eliminates the electrical connection between the radiating conductors and feed by employing dielectric substrates separated by a ground plane. If exact combination of slot and shape of feed is chosen, it gives an optimum impedance bandwidth with an improved radiation pattern.

description: We present the results of multiple simulations of open clusters, modelling the dynamics of a population of brown dwarf members. We consider the effects of a large range of primordial binary populations, including the possibilities of having brown dwarf members contained within a binary system. We also examine the effects of various cluster diameters and masses. Our examination of a population of wide binary systems containing brown dwarfs, reveals evidence for exchange reactions whereby the brown dwarf is ejected from the system and replaced by a heavier main-sequence star. We find that there exists the possibility of hiding a large fraction of the brown dwarfs contained within the primordial binary population. We conclude that it is probable that the majority of brown dwarfs are contained within primordial binary systems which then hides a large proportion of them from detection.

We provide several analytic criteria that help guide the selection of gravitational softening for hydrodynamical simulations, and present results from runs that both adhere to and deviate from them. Unlike dark matter-only simulations, hydrodynamical simulations exhibit a strong sensitivity to gravitational softening, and care must be taken when selecting numerical parameters. Our results--which focus mainly on star formation histories, galaxy stellar mass functions and sizes--illuminate three main considerations. First, softening imposes a minimum resolved escape speed, $v_ε$, due to the binding energy between gas particles. Runs that adopt such small softening lengths that $v_ε\gt 10\,{\rm km s^{-1}}$ (the sound speed in ionised $\sim 10^4\,{\rm K}$ gas) suffer from reduced effects of photo-heating. Second, feedback from stars or active galactic nuclei may suffer from numerical over-cooling if the gravitational softening length is chosen below a critical value, $ε_{\rm eFB}$. Third, we note that small softening lengths exacerbate the segregation of stars and dark matter particles in halo centres, often leading to the counter-intuitive result that galaxy sizes {\em increase} as softening is reduced. The structure of dark matter haloes in hydrodynamical runs respond to softening in a way that reflects the sensitivity of their galaxy populations to numerical parameters.

description: We construct a family of explicit rotational solutions to the nonlinear governing equations for water waves, describing edge waves propagating over a plane-sloping beach. A detailed analysis of the edge wave dynamics and of the run-up pattern is made possible by the use of the Lagrangian approach to the water motion. A graphical representation of the edge wave is also presented.

description: Open government promises increased transparency by providing its citizens datasets about city processes. Open data portals have been emerging all over the world as mines of open geographic datasets. Thematic web maps are key to understanding these open geographic datasets. Current thematic web maps are created by programmers and/or cartographers, and thus are not designed to be easily reused with new geographic datasets. As a result, they pose several challenges to non-experts wanting to adapt them to new scenarios. This article introduces a semi-automatic approach for the creation of thematic web maps by and for users with no prior training in cartography. The approach relies on the mapping between Stevens’ data types and Bertin’s visual variables, to suggest (meaningful) thematic map visualizations for a given input geographic dataset. It was implemented as a web prototype in AngularJS and evaluated with 19 participants. Results from the user study suggest that despite facing a few challenges in accurately identifying Stevens’ data types, participants managed to successfully create web maps and correctly answer spatial questions. The prototype and insights gathered from the user study are relevant to making cartographic products more accessible to a broader population, and open geographic data more usable in the context of an open government.
Défaillance de l'Economie Publique en République Démocratique du Congo, Une Analyse Théorique et Empirique

description: D’une manière succincte, l’économie publique étudie les justifications et les effets de l’intervention de l’Etat dans l’économie. Selon Jacques Drève, l’économie publique est née dans les années 1950 lorsqu’elle s’est distinguée de la « Finance Publique », qui étudie spécifiquement le financement de l’Etat.

        Quand on parle de la défaillance de l’Economie Publique ; c’est le fait que l’Etat engendre des inefficacités en matière d’intervention Economique.
Democratic Speech in Divided Times

description: Democratic theorists have influentially argued that inclusive deliberation, where citizens voice their concerns and exchange justifications, is crucial to democracy. However, this deliberative ideal has come under sustained attack for being excessively utopian. As a result, to make this ideal more relevant and action-guiding, the present thesis investigates what norms should govern deliberation in political settings marked by severe social divisions. After motivating this project (Chapter 1), I defend the following account of deliberation. Although the requirement that deliberators appeal to shared reasons is morally attractive, even the weakest variant of this norm risks excluding too many considerations from the public deliberation of divided societies. To offset these exclusionary tendencies, I argue that public deliberation should give a greater role to emotionally-charged forms of speech, such as narrative (Chapter 2). Now, this last suggestion might seem overly inclusive, by opening the door for intensely angry narratives and for narratives expressing degrading or disrespectful views. In response to this ‘overinclusiveness’ concern, I argue 1) that degrading or disrespectful public speech is best countered through state-backed counterspeech, rather than through coercive legal norms that forcibly eliminate it from public discourse (Chapter 3) and 2) that narratives expressing anger in fact have a crucial epistemic role to play in divided societies, by enhancing our understanding of persisting injustices (Chapter 4). The final two chapters address a pressing worry: that the deliberative norms I advance demand too much of actual citizens. One might think that if citizens distrust each other and are highly ignorant about politics, they will be unable to deliberate fruitfully. But these problems are not decisive against my account. Chapter 5 investigates how the kind of public dialogue I defend offers important resources for rebuilding trust and goodwill in divided societies. As for political ignorance, Chapter 6 demonstrates that it is equally problematic for other political systems, democratic and non-democratic. Since this ignorance threatens all accounts, the solution is not to abandon inclusive deliberation, but rather to tackle political ignorance itself.

description: The General Data Protection Regulation (GDPR) provides new rights and protections to European people concerning their personal data. We analyze GDPR from a systems perspective, translating its legal articles into a set of capabilities and characteristics that compliant systems must support. Our analysis reveals the phenomenon of metadata explosion, wherein large quantities of metadata needs to be stored along with the personal data to satisfy the GDPR requirements. Our analysis also helps us identify new workloads that must be supported under GDPR. We design and implement an open-source benchmark called GDPRbench that consists of workloads and metrics needed to understand and assess personal-data processing database systems. To gauge the readiness of modern database systems for GDPR, we follow best practices and developer recommendations to modify Redis, PostgreSQL, and a commercial database system to be GDPR compliant. Our experiments demonstrate that the resulting GDPR compliant systems achieve poor performance on GPDR workloads, and that performance scales poorly as the volume of personal data increases. We discuss the real-world implications of these findings, and identify research challenges towards making GDPR compliance efficient in production environments. We release all of our software artifacts and datasets at http://www.gdprbench.org

description: We present first results from a 325 ks observation of the Seyfert 1 galaxy MCG-6-30-15 with XMM-Newton and BeppoSAX. The strong, broad, skewed iron line is clearly detected and is well characterised by a steep emissivity profile within 6r_g (i.e. 6GM/c^2) and a flatter profile beyond. The inner radius of the emission appears to lie at about 2r_g, consistent with results reported from both an earlier XMM-Newton observation of MCG-6-30-15 by Wilms et al. and part of an ASCA observation by Iwasawa et al. when the source was in a lower flux state. The radius and steep emissivity profile do depend however on an assumed incident power-law continuum and a lack of complex absorption above 2.5 keV. The blue wing of the line profile is indented, either by absorption at about 6.7 keV or by a hydrogenic iron emission line. The broad iron line flux does not follow the continuum variations in a simple manner.

description: During the RDA VP24 Breakout Session 2 meeting we presented our first set of finalized machine-actionable deliverables and the lineage of these outputs stemming from recent community-driven MOMSI WG activities. This session will included interactive discussions and demos of our new Multi-omics data standards landscape review dashboard repository (Deliverable 1a) supported under the RDA TIGER program support services. We also introduced our MOMSI WG GitHub repository sustainability plan curation workflow connecting to our FAIRsharing Standards Collection (Deliverable 1b) in collaboration with the RDA FAIRsharing WG. This is a great opportunity for community members (new and existing) to provide feedback on recent outputs as we prepare for community review feedback to be included in our upcoming recommendation materials and linked publications. During this session we introduced scope for our last set of MOMSI WG activity deliverables (multi-omics collection gap analysis + recommendation manuscript) and outlined aims for use-case engagements. Outcomes from this session serve to promote ongoing RDA collaborations in building new community partnerships for adoption of MOMSI WG open resources and recommendations, aimed to empower Multi-omics standard harmonization and continuous educational awareness.

 

NOTE: In this presentation we hightlight documentation covering novel capabilities and curation workflows implemented in our new Multi-Omics Standards Landscape Review GitHub repository and interactive web-based dashboard tool. The dashboard presented here (linked GitHub repository and live feedback form) are set to be updated and fully released by end of April 2025 for community review and feedback.
