Solid Earth response of the Patagonia Andes to post-Little Ice Age glacial retreat
Creators: name: Douglas Wiens
name: Maria Beatrice Magnani
Publisher: name: International Federation of Digital Seismograph Networks
Year: 2018

description: The goal of this proposal is to provide first-order observational constraints on glacial isostatic adjustment (GIA) around the rapidly shrinking Southern Patagonian Icefield (SPI), where the fastest uplift rates on the planet have been measured. This region offers a unique opportunity to understand how complex tectonics including a volcanic arc and "slab window" may strongly influence GIA. In this study, we propose a five-pronged approach to constrain the ice sheet and erosional/depositional history as well as the solid Earth response, and to integrate the results through ice sheet and geodynamic modeling. We propose to: 1) deploy an array of 28 broadband seismographs around the SPI to image mantle structure and provide independent constraints on the 3D viscosity structure and lithospheric thickness required for GIA modeling; 2) collect 480 km of high resolution marine seismic reflection data on the largest glacial lake in the region (Lago Argentino), where eight outlet glaciers drain, to determine submerged former ice frontal positions, and rates and patterns of erosion/deposition; 3) collect ~20 10m-long piston cores from the lake and glacial valleys to provide an annually resolved sediment record that will help constrain the interpretation of marine seismic data; 4) establish the terrestrial chronology of deglaciation through mapping and dating; and 5) build models of erosion, deposition, ice dynamics, and GIA, that together will simulate the geophysical state and glacial history of the SPI and its environs.

description: We discuss the coupling between dark energy and matter by considering a homogeneous tachyonic scalar field as a candidate for dark energy. We obtained the functional form of scale factor by assuming that the coupling strength depends linearly on the Hubble parameter and energy density. We also estimated the cosmic age of the universe for different values of coupling constant.

description: Blockchain-based cryptocurrencies have demonstrated how to securely implement traditionally centralized systems, such as currencies, in a decentralized fashion. However, there have been few measurement studies on the level of decentralization they achieve in practice. We present a measurement study on various decentralization metrics of two of the leading cryptocurrencies with the largest market capitalization and user base, Bitcoin and Ethereum. We investigate the extent of decentralization by measuring the network resources of nodes and the interconnection among them, the protocol requirements affecting the operation of nodes, and the robustness of the two systems against attacks. In particular, we adapted existing internet measurement techniques and used the Falcon Relay Network as a novel measurement tool to obtain our data. We discovered that neither Bitcoin nor Ethereum has strictly better properties than the other. We also provide concrete suggestions for improving both systems.

description: Consider a linear model Y = Xβ + z, where X = Xn;p and z ≈ N(0; In). The vector β is unknown and it is of interest to separate its nonzero coordinates from the zero ones (i.e., variable selection). Motivated by examples in long-memory time series [11] and change point problem [2], we are primarily interested in the case where the Gram matrix G = X1X is non-sparse but sparsifiable by a finite order linear filter. We focus on the regime where signals are both rare and weak so that successful variable selection is very challenging but is still possible. We approach this problem by a new procedure called the Covariance Assisted Screening and Estimation (CASE). CASE first uses a linear filtering to reduce the original setting to a new regression model where the corresponding Gram (covariance) matrix is sparse. The new covariance matrix induces a sparse graph, which guides us to conduct multivariate screening without visiting all the submodels. By interacting with the signal sparsity, the graph enables us to decompose the original problem into many separated small-size subproblems (if only we know where they are!). Linear filtering also induces a so-called problem of information leakage, which can be overcome by the newly introduced patching technique. Together, these give rise to CASE, which is a two-stage Screen and Clean [10, 32] procedure, where we first identify candidates of these submodels by patching and screening, and then re-examine each candidate to remove false positives.

Seismo Acoustic Study of Rocket Launches from Kennedy Space Center

Publisher: name: International Federation of Digital Seismograph Networks
Year: 2018

description: Since February 2016 I have had a Trillium C-PH 120s and an array of infraBSU sensors deployed at Kennedy Space Center (KSC) and I have recorded ~15 rocket launches. The primary motivations have been (1) to test and our calibrate our sensors, and (2) to train students in seismic field techniques as a component of a time series analysis class that I teach. Soon I am planning to telemeter our primary site, BCHH, to the USF seismic lab. Occasionally this network has been augmented by up to 3 additional stations, and that has given us hints of the more complex seismic-acoustic wavefield. For example, we find that the amplitude of the rocket jet noise increases with radial distance from the rocket. We are exploring techniques to determine the trajectory of rockets based on amplitude-source location (a method I co-developed for locating pyroclastic density currents and lahars), and the Doppler shift recorded. And we are exploring if there are characteristic differences in the waveforms and spectra of Falcon-9, Atlas-5 and Delta-IV rockets, which is hard to tease out from a single station because the launch sites & distances are also different. To be able to explore these questions better, we need a temporary deployment of additional stations and a wider aperture network. The first experiment would be to deploy all sensors at our primary site, the Astronaut Beach House (station BCHH), to conduct a huddle test during a rocket launch. The second experiment would be to deploy a linear array to understand better the P, S and surface wave structure at Kennedy Space Center & verify the amplitude-vs-distance decay law for seismic and acoustic waves. For this we would likely use a static launch test (rocket engines ignite, but rocket stays on the ground) rather than a launch. The third and primary experiment, would be to deploy a 7-station network of L-22 short period seismometers and RT130 dataloggers & leave this in place for at least 6 months to capture several launches. The network would have an aperture of about 15 to 20-km.
Arguments against a dominantly hadronic origin of the VHE radiation from the supernova remnant RX J1713-3946

description: The flux of photons with energies above 1 TeV from the direction of the centre and a cloud in the western part of the nearby southern supernova remnant (SNR) RX J1713.7-3946 is calculated in the ``hadronic scenario'' that aims to explain the intense VHE radiation from this remnant with the decay of π_0 pions produced in nuclear collisions. The expected flux from its centre is found to fall short by about factor 40 from the one observed by the HESS collaboration. This discrepancy presents a serious obstacle to the ``hadronic scenario''. The theoretically expected flux from the molecular cloud exceeds the one observed by HESS by at least a factor 3. While the size of this discrepancy might still seem acceptable in the face of various theoretical uncertainties, the result strongly suggests a strict spatial correlation of the cloud with an excess of TeV γradiation. The observational lack of such correlations in the remnant reported by HESS is another counter argument against the hadronic scenario. In combination these arguments cannot be refuted by choosing certain parameters for the total energy or acceleration efficiency of the SNR.

description: In the degree work that you will find below it will be based on the metaphor of that butterfly that, due to the adversities that it encounters in its daily life, must migrate and although it sounds easy to leave and start again, for seven butterflies it has not been that way, It is a new beginning, with your family and with your environment. In this sense, seven types of butterflies will be taken into account, migrating from different cities in Colombia, in which they had new family creations, preserving single parenthood with a female head of household. This is how it has been determined that the research will include the well-being and social development of migrant families with female heads of household in the city of Bogotá, in relation to their family dynamics and territoriality, for the visibility of women in their role and their single parent structure. By managing to find the gap in knowledge about the well-being and social development of butterflies in relation to their female head of household, their migration and their daily lives, it has been identified to know key concepts that will determine the knowledge of this.

description: Entre 7 et 37% des hommes auraient été victimes d’abus sexuels avant l’âge adulte (Tourigny, Hébert, Joly, Cyr, & Baril, 2008). Cet important problème de santé publique engendre des répercussions qui perdurent dans le temps et qui touchent plusieurs sphères de la vie des hommes. Certaines études s’intéressent aux conséquences des abus ainsi qu’au processus de dévoilement des victimes. Toutefois, les connaissances sont peu développées en ce qui a trait aux façons d’aider les hommes ayant subi des abus sexuels durant l’enfance. Puisque les traumatismes sont vécus et exprimés de manières différentes, entre autres, en fonction du genre de la victime, la prise en charge des hommes victimisés devraient être adaptés à cette réalité (Teram, Stalker, Hovey, Schachter, & Lasiuk, 2006; Alaggia, & Millington, 2008; Godbout et collab., 2019). Cette recherche documente les perceptions d’hommes ayant vécu des abus sexuels durant l’enfance sur les services qu’ils ont reçus dans des ressources spécialisées en victimisation sexuelle au Québec. Les résultats ont été recueillis auprès de dix hommes par l’entremise d’entrevues semi-dirigées. Les propos des participants de cette étude témoignent d’un niveau d’appréciation élevé des services. Néanmoins, ils mettent aussi en lumière certains obstacles auxquels les hommes doivent faire face au cours de leur démarche de demande d’aide. Certaines recommandations pour la pratique peuvent être formulées notamment : les apports de l’intervention de groupe auprès de cette population ainsi que l’importance d’adopter une approche sensible au genre et au traumatisme.

Les résultats montrent que l’organisme a fait preuve d’une réelle ouverture aux contributions des internautes et que celle-ci s’inscrit dans une attitude socioterminologique globale qui a pour objectif l’implantation réussie des termes dans l’usage. /// This article, framed within studies on term implantation, presents the results of the online collaborative project En bons termes between a group of speakers and various actors of language and terminology planning in Canada, including the Office québécois de la langue française (OQLF). The objective of the collaboration was to find suitable terminological solutions to name new concepts in French. With a focus on the terms that were published on 11 term records in the OQLF’s termbank, Le Grand dictionnaire terminologique, we analyse how the OQLF integrated speakers’ suggestions, including the space and acceptability status that it gave them in the records. Conclusions show that the OQLF was open to speakers’ contributions, as per the general socioterminological orientation it adopted over the last couple of decades to ensure the successful implantation of its terminology.

description: The pressure on software developers to produce secure software has never been greater. But what does security look like in environments that do not produce security-critical software? In answer to this question, this multi-sited ethnographic study characterizes security episodes and identifies five typical behaviors in software development. Using theory drawn from information security and motivation research in software engineering, this article characterizes key ways in which individual developers form security responses to meet the demands of particular circumstances, providing a framework managers and teams can use to recognize, understand, and alter security activity in their environments.

We show uniform-in-time boundedness of solutions, which means, that unlike in higher dimensions, there is no critical mass phenomenon in the case of critical diffusion. To this end we utilize estimates from a well-known Lyapunov functional and a recently introduced new Lyapunov-like functional in [3].
Correlation-sharing for Detection of Differential Gene Expression

description: We propose a method for detecting differential gene expression that exploits the correlation between genes. Our proposal averages the univariate scores of each feature with the scores in correlation neighborhoods. In a number of real and simulated examples, the new method often exhibits lower false discovery rates than simple t-statistic thresholding. We also provide some analysis of the asymptotic behavior of our proposal. The general idea of correlation-sharing can be applied to other prediction problems involving a large number of correlated features. We give an example in protein mass spectrometry.

description: The long therm behavior of chaotic flows is investigated by means of time dependent frequency analysis. The system under test consists of an electrically conducting fluid, confined between two differentially rotating spheres. The spherical setup is exposed to an axial magnetic field. The classical Fourier Transform method provides a first estimation of the time dependence of the frequencies associated to the flow, as well as its volume-averaged properties. It is however unable to detect strange attractors close to regular solutions in the Feigenbaum as well as Newhouse-Ruelle-Takens bifurcation scenarios. It is shown that Laskar's frequency algorithm is sufficiently accurate to identify these strange attractors and thus is an efficient tool for classification of chaotic flows in high dimensional dynamical systems. Our analysis of several chaotic solutions, obtained at different magnetic field strengths, reveals a strong robustness of the main frequency of the flow. This frequency is associated to an azimuthal drift and it is very close to the frequency of the underlying unstable rotating wave. In contrast, the main frequency of volume-averaged properties can vary almost one order of magnitude as the magnetic forcing is decreased. We conclude that, at the moderate differential rotation considered, unstable rotating waves provide a good description of the variation of the main time scale of any flow with respective variations in the magnetic field.

description: The network is located on Sørsdal Glacier, a moderately-sized marine-terminating outlet glacier that is easily accessible from Davis Station, Antarctica. Every austral summer Sørsdal Glacier experiences melting in its lower reaches and heavily crevassed ice tongue, with extensive melt ponding. Lakes, each several square-kilometers in size, form and drain perennially, although the mechanisms by which they do so are unclear. The network consists of nine 4.5 Hz GS-11D Geophones with Reftek data loggers around one of the supraglacial lake. In addition, we will deploy four Guralp DMC-40TDs at the ice surface along the hypothesized shallow englacial drainage pathway, where exact positions will be determined from existing and new GPR data as well as field safety considerations. Based on previous experience in Greenland and West Antarctica we expect these seismometers to allow temporal changes in the seismic noise field associated with englacial water flow and weak basal seismic events to be characterized.
$A_4$ Flavour Model for Dirac Neutrinos: Type I and Inverse Seesaw

Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: We propose two different seesaw models namely, type I and inverse seesaw to realise light Dirac neutrinos within the framework of $A_4$ discrete flavour symmetry. The additional fields and their transformations under the flavour symmetries are chosen in such a way that naturally predicts the hierarchies of different elements of the seesaw mass matrices in these two types of seesaw mechanisms. For generic choices of flavon alignments, both the models predict normal hierarchical light neutrino masses with the atmospheric mixing angle in the lower octant. Apart from predicting interesting correlations between different neutrino parameters as well as between neutrino and model parameters, the model also predicts the leptonic Dirac CP phase to lie in a specific range -$π/3$ to $π/3$. While the type I seesaw model predicts smaller values of absolute neutrino mass, the inverse seesaw predictions for the absolute neutrino masses can saturate the cosmological upper bound on sum of absolute neutrino masses for certain choices of model parameters.

description: We consider the problem of recovering the initial value, from the trace on the light cone, of the solution of an initial value problem for the wave equation. When the space is odd dimensional, we show that the map from the initial value to the traces of the (even or odd in time) solutions on the light cone is an isometry and we characterize the range of this map and construct its inverse. We do this by relating the problem to the recovery of a function from its spherical means over all spheres through the origin, which in turn is related to the Radon transform inversion via the inversion map on R^n.

Perspectives on constraining a cosmological constant-type parameter with pulsar timing in the Galactic Center

description: Independent tests aiming to constrain the value of the cosmological constant $Λ$ are usually difficult because of its extreme smallness $\left(Λ\simeq 1\times 10^{-52}~\textrm{m}^{-2},~\textrm{or}~2.89\times 10^{-122}~\textrm{in Planck units}\right)$. Bounds on it from Solar System orbital motions determined with spacecraft tracking are currently at the $\simeq 10^{-43}-10^{-44}~\textrm{m}^{-2}~\left(5-1\times 10^{-113}~\textrm{in Planck units}\right)$ level, but they may turn out to be somewhat optimistic since $Λ$ has not yet been explicitly modeled in the planetary data reductions. Accurate $\left(σ_{τ_\textrm{p}}\simeq 1-10~μ\textrm{s}\right)$ timing of expected pulsars orbiting the Black Hole at the Galactic Center, preferably along highly eccentric and wide orbits, might, at least in principle, improve the planetary constraints by several orders of magnitude. By looking at the average time shift per orbit $\overline{Δδτ}^Λ_\textrm{p}$, a S2-like orbital configuration with $e=0.8839,~P_\textrm{b}=16~\textrm{yr}$ would allow to obtain preliminarily an upper bound of the order of $\left|Λ\right|\lesssim 9\times 10^{-47}~\textrm{m}^{-2}~\left(\lesssim 2\times 10^{-116}~\textrm{in Planck units}\right)$ if only $σ_{τ_\textrm{p}}$ were to be considered. Our results can be easily extended to modified models of gravity using $Λ-$type parameters.

description: Before the development of the true dome, many ancient cultures used the technique of corbelling to roof spaces. Recently, a series of related statistical models have been proposed in the literature for explaining how corbelled domes might have been constructed. The most sophisticated of these models is based on a piecewise linear structure, with an unknown number of changepoints, to guide the building process. This model is analyzed by the reversible jump Markov Chain Monte Carlo (MCMC) technique. All models considered to date have been two-dimensional, that is, they have taken a single cross section through the dome; even when more extensive data, in the form of measurements on multiple slices through the dome, have been available, these have been averaged together for the purposes of analysis. In this paper, we extend the two-dimensional analysis to a three-dimensional analysis, that takes full advantage of the data collected by the archaeologists and of the rotational symmetries inherent in the structure. We also explore ways of graphically presenting the results from a complex, reversible jump MCMC implementation, in order to check convergence, good mixing, and appropriate exploration of the (high dimensional and varying dimension) parameter space. The model and the graphical techniques are demonstrated on the Treasury of Atreus in Mycenae, Greece, one of the finest extant examples of the corbelling method.

description: T H E CENTRAL HISTORIOGRAPHICAL QUESTION of the 1980s results from the research activity of the 1970s: What are the relationships among the new subfields of social history and between these subfields and the traditional "grand events"? Historians of various orientations have given this question a great deal of consideration in recent years and not surprisingly have come to quite different conclusions. Nonetheless, one trend is clear. The talk is now of synthesis, of integration, of coherence. In the 1970s, the development of new fields of social history represented an expanding historical consciousness; now this development is often discussed in terms of fragmentation. The 1980s has become a decade of nostalgia, of longing for a time when writing about the past seemed a lot simpler and the results more fun to read.
Multicritical point on the de Almeida-Thouless line in spin glasses in $d>6$ dimensions

description: The de Almeida-Thouless (AT) line in Ising spin glasses is the phase boundary in the temperature $T$ and magnetic field $h$ plane below which replica symmetry is broken. Using perturbative renormalization group (RG) methods, we show that when the dimension $d$ of space is just above $6$ there is a multicritical point (MCP) on the AT line, which separates a low-field regime, in which the critical exponents have mean-field values, from a high-field regime where the RG flows run away to infinite coupling strength; as $d$ approaches $6$ from above, the location of the MCP approaches the zero-field critical point exponentially in $1/(d-6)$. Thus on the AT line perturbation theory for the critical properties breaks down at sufficiently large magnetic field even above $6$ dimensions, as well as for all non-zero fields when $d\leq 6$ as was known previously. We calculate the exponents at the MCP to first order in $\varepsilon=d-6>0$. The fate of the MCP as $d$ increases from just above 6 to infinity is not known.

description: The analysis of climatological data often involves statistical significance testing at many locations. While the field significance approach determines if a field as a whole is significant, a multiple testing procedure determines which particular tests are significant. Many such procedures are available, most of which control, for every test, the probability of detecting significance that does not really exist. The aim of this paper is to introduce the novel “false discovery rate” approach, which controls the false rejections in a more meaningful way. Specifically, it controls a priori the expected proportion of falsely rejected tests out of all rejected tests; additionally, the test results are more easily interpretable. The paper also investigates the best way to apply a false discovery rate (FDR) approach to spatially correlated data, which are common in climatology. The most straightforward method for controlling the FDR makes an assumption of independence between tests, while other FDR-controlling methods make less stringent assumptions. In a simulation study involving data with correlation structure similar to that of a real climatological dataset, the simple FDR method does control the proportion of falsely rejected hypotheses despite the violation of assumptions, while a more complicated method involves more computation with little gain in detecting alternative hypotheses. A very general method that makes no assumptions controls the proportion of falsely rejected hypotheses but at the cost of detecting few alternative hypotheses. Despite its unrealistic assumption, based on the simulation results, the authors suggest the use of the straightforward FDR-controlling method and provide a simple modification that increases the power to detect alternative hypotheses.
Fort Boise passive seismic water-recharge monitoring experiment

Publisher: name: International Federation of Digital Seismograph Networks
Year: 2018

description: We will record three-component passive seismic noise data at Fort Boise, Boise, ID. These data will be used to monitor time-lapse changes in ground water. The Fort Boise area lies at the edge of the Idaho Batholith and the northern extent of the Western Snake River Plain -- the Boise Front. In this area there is ongoing geothermal resource extraction by the City of Boise. Ground water recharge in this region is critical to sustaining the resource. As more development occurs in the surrounding foothills, snow-melt runoff patterns begin to change. We will use seismic noise data to image the underground velocity structure during different time periods and determine changes related to ground water throughout a winter-spring melt run-off cycle. Seismic noise will be generated by traffic on the roads surrounding the site. We will arrange 62 three-component sensors to record noise from January 2018 to April 2018. We have geological knowledge and existing seismic reflection data for this area; we also have wells and drill logs that will be used to inform the seismic imaging and monitoring. With this background knowledge we have a very good initial model for this area, which will enable use to resolve small changes in the subsurface. We will also apply our new ambient noise full-waveform inversion code to these data. This research is important for passive-source surface-wave applications in urban areas. We will gain experience using these methods to investigate and monitor underground structures in urban settings.

description: La conservación de los ecosistemas estratégicos del país realizada a través, entre otros, del Sistema Nacional de Áreas Protegidas (SINAP) es uno de los elementos protagónicos del Sistema Nacional Ambiental, por la cual es importante identificar opciones de mejora que le permitan adaptarse a fenómenos como el de la urbanización. Por lo anterior, el presente trabajo de investigación, usando una metodología teórico-deductiva, busca identificar las falencias que el SINAP presenta en relación con la protección de los ecosistemas urbanos, con la finalidad de encontrar las mencionadas opciones de mejora. El trabajo está divido en tres ítems, el primero encargado de estudiar las generalidades del fenómeno urbano desde el punto de vista global, latinoamericano y nacional. En el segundo ítem, se revisará de forma directa el actual SINAP, identificando sus falencias y planteando algunas propuestas de ajustes normativos que podrían mejorarlo. Finalmente, en el tercer ítem se abordarán algunos ejemplos de creación de sistemas locales de áreas protegidas adelantados por ciudades como Bogotá y Medellín. Una conclusión general sostiene que las acciones locales de las ciudades para la conservación de los ecosistemas urbanos tienen efectos más allá de su jurisdicción, permitiendo alcanzar objetivos ambientales nacionales e inclusive algunos globales establecidos en diferentes instrumentos internacionales, razón por la cual es importante un ajuste normativo al SINAP.

description: A search for massive neutrinos has been made in the decay $π\rightarrow e^+ ν$. No evidence was found for extra peaks in the positron energy spectrum indicative of pion decays involving massive neutrinos ($π\rightarrow e^+ ν_h$). Upper limits (90 \% C.L.) on the neutrino mixing matrix element $|U_{ei}|^2$ in the neutrino mass region 60--135 MeV/$c^2$ were set, which are %representing an order of magnitude improvement over previous results.

description: New observations have revealed that changes in ice sheets are occurring at rates far exceeding
the millennial time scales predicted by traditional models (Paterson, 1994). Our inability to fully
model these changes limits our ability to make predictions about their future contributions to
sea-level rise (Intergovernmental Panel on Climate Change, 2007). Many of these changes are
taking place in the large ice streams and outlet glaciers that drain the interiors of ice sheets. One
such dynamic region is the Whillans Ice Stream (WIS), a large outlet for ice that drains from the
interior of the West Antarctic Ice Sheet (WAIS) into the Ross Ice Shelf.

description: The New England Damage Experiment was conducted in 2008. Phase II will answer questions raised since the completion of that experiment. The overall goal is to examine shear wave generation from explosions, but during this experiment we will use TNT equivalent amounts of each explosive (Black Powder, ANFO, Comp B) instead of equal weights. We will also examine explosions in rock damaged by the 2008 explosions with "reshoots".
