description: In the circular case of the coplanar Restricted Three-body Problem, we studied how the family of quasi-satellite (QS) periodic orbits allows to define an associated libration center. Using the averaged problem, we highlighted a validity limit of this one: for QS orbits with low eccentricities, the averaged problem does not correspond to the real problem. We do the same procedure to L 3 , L 4 and L 5 emerging periodic orbits families and remarked that for very high eccentricities F L4 and F L5 merge with F L3 which bifurcates to a stable family.

The effects of colonial power relations in indigenous rights in Brazil : a legal, historical and sociological analysis

description: Second semester University: University of Nottingham
description: This thesis seeks to address the effects of colonialism on indigenous rights in Brazil. Through literary research, it seeks to demonstrate how the relationships established in the period of Portuguese domination were perpetuated in time, consolidating and threatening the life, customs and lands of indigenous peoples in Brazil. This study is especially relevant to raise the understanding of why native peoples are today in a state of vulnerability and how colonial relations contributed to their finding themselves in this situation. It was concluded that only through breaking with these colonial models of power is it possible to devise truly effective solutions to protect indigenous peoples. Thus, it was found that colonial power relations are still very present both in the national reality of Brazil and in the international community. Furthermore, these relationships are very harmful, since they place non- Western cultures in a place of inferiority, seeking to assimilate and erase them. In this way, they must be broken so that the real and effective expression of Brazilian multiculturalism can be possible, in order to allow not only the expansion of the expression and political participation of these peoples, but also to allow the existence of different ways of living, thinking and to organise socially, economically and politically.
Temperature Stabilization of the Borexino Detector for the CNO Quest

Publisher: name: Zenodo
Year: 2020

description: The detection of the Solar Neutrino interaction rate from the CNO-cycle through the spectral analysis in Borexino is extremely difficult, given its spectral similarity with the Bi-210 background. The current strategy is based on the Bi-210 (β-, τ = 7 d) background independent constraint, coming from Pb-210 (β-, τ = 32 y) and decaying into Po-210(α, τ = 200 d) through the A=210 decay chain. In practice, the Bi-210 rate can be inferred by the Po-210 rate if sufficient thermodynamics equilibrium conditions of the detector are reached. Since 2011, we have been observing consistent migrations (convection and diffusion) of Po-210 in the scintillator liquid from the containment vessel. This observation has motivated the Collaboration to make an effort in deploying temperature control and thermal insulation systems to reduce Po-210 migration. Detailed 2D and 3D fluid dynamics simulations and performance of the thermal insulation system will be discussed.

description: We present a physics-informed deep learning model for the transient heat transfer analysis of three-dimensional functionally graded materials (FGMs) employing a Runge–Kutta discrete time scheme. Firstly, the governing equation, associated boundary conditions and the initial condition for transient heat transfer analysis of FGMs with exponential material variations are presented. Then, the deep collocation method with the Runge–Kutta integration scheme for transient analysis is introduced. The prior physics that helps to generalize the physics-informed deep learning model is introduced by constraining the temperature variable with discrete time schemes and initial/boundary conditions. Further the fitted activation functions suitable for dynamic analysis are presented. Finally, we validate our approach through several numerical examples on FGMs with irregular shapes and a variety of boundary conditions. From numerical experiments, the predicted results with PIDL demonstrate well agreement with analytical solutions and other numerical methods in predicting of both temperature and flux distributions and can be adaptive to transient analysis of FGMs with different shapes, which can be the promising surrogate model in transient dynamic analysis.

description: The XENON100 experiment is the second phase of the XENON program for the direct detection of the dark matter in the universe. The XENON100 detector is a two-phase Time Projection Chamber filled with 161 kg of ultra pure liquid xenon. The results from 224.6 live days of dark matter search with XENON100 are presented. No evidence for dark matter in the form of WIMPs is found, excluding spin-independent WIMP-nucleon scattering cross sections above 2 $\times$ 10$^{-45}$ cm$^2$ for a 55 GeV/c$^2$ WIMP at 90% confidence level (C.L.). The most stringent limit is established on the spin-dependent WIMP-neutron interaction for WIMP masses above 6 GeV/c$^2$, with a minimum cross section of 3.5 $\times$ 10$^{-40}$ cm$^2$ (90% C.L.) for a 45 GeV/c$^2$ WIMP. The same dataset is used to search for axions and axion-like-particles. The best limits to date are set on the axion-electron coupling constant for solar axions, $g_{Ae}$ < 7.7 $\times$ 10$^{-12}$ (90% C.L.), and for axion-like-particles, $g_{Ae}$ < 1 $\times$ 10$^{-12}$ (90% C.L.) for masses between 5 and 10 keV/c$^2$.

Parameterization and applications of the low momentum transfer nucleon vector form factors

name: Hill, Richard
Publisher: name: Zenodo
Year: 2020

description: We present the proton and neutron vector form factors in a convenient parametric form that is model independent and optimized for momentum transfers $\leq$ few GeV$^2$. The form factors are determined from a global fit to electron scattering data and precise charge radii measurements. We apply a new treatment of radiative corrections. We evaluate the neutrino–nucleon scattering cross sections at GeV energies of neutrino oscillation experiments. The neutrino–nucleon charged current quasielastic cross section differs by 3–5% compared to commonly-used form factor models when the vector form factors are constrained by recent high-statistics electron-proton scattering data from the A1 collaboration. A primary goal of this work is to provide a consistent framework for applications such as neutrino event generators to propagate form factor constraints and uncertainties into cross section predictions.
Models and Information Rates for Wiener Phase Noise Channels

Publisher: name: arXiv
Year: 2015
Subjects: subject: Information Theory (cs.IT)
subject: FOS: Computer and information sciences

description: A waveform channel is considered where the transmitted signal is corrupted by Wiener phase noise and additive white Gaussian noise. A discrete-time channel model that takes into account the effect of filtering on the phase noise is developed. The model is based on a multi-sample receiver, i.e., an integrate-and-dump filter whose output is sampled at a rate higher than the signaling rate. It is shown that, at high Signal-to-Noise Ratio (SNR), the multi-sample receiver achieves a rate that grows logarithmically with the SNR if the number of samples per symbol (oversampling factor) grows with the cubic root of the SNR. Moreover, the pre-log factor is at least 1/2 and can be achieved by amplitude modulation. For an approximate discrete-time model of the multi-sample receiver, the capacity pre-log at high SNR is shown to be at least 3/4 if the number of samples per symbol grows with the square root of the SNR. The analysis shows that phase modulation achieves a pre-log of at least 1/4 while amplitude modulation still achieves a pre-log of 1/2. This is strictly greater than the capacity pre-log of the (approximate) discrete-time Wiener phase noise channel with only one sample per symbol, which is 1/2. Numerical simulations are used to compute lower bounds on the information rates achieved by the multi-sample receiver. The simulations show that oversampling is beneficial for both strong and weak phase noise at high SNR. In fact, the information rates are sometimes substantially larger than when using commonly-used approximate discrete-time models.

description: Randomness is one of the most important resources in modern information science, since encryption founds upon the trust in random numbers. Since it is impossible to prove if an existing random bit string is truly random, it is relevant that they be generated in a trust worthy process. This requires specialized hardware for random numbers, for example a die or a tossed coin. But when all input parameters are known, their outcome might still be predicted. A quantum mechanical superposition allows for provably true random bit generation. In the past decade many quantum random number generators (QRNGs) were realized. A photonic implementation is described as a photon which impinges on a beam splitter, but such a protocol is rarely realized with non-classical light or anti-bunched single photons. Instead, laser sources or light emitting diodes are used. Here we analyze the difference in generating a true random bit string with a laser and with anti-bunched light. We show that a single photon source provides more randomness than even a brighter laser. This gain of usable entropy proves the advantages of true single photons versus coherent input states of light in an experimental implementation. The underlying advantage can be adapted to microscopy and sensing.

description: Neutrinos travel nearly unattenuated over cosmological distances making them an excellent messenger to study high-energy processes occurring in the universe. IceCube, the world's largest and most sensitive astrophysical neutrino detector, reported a high-energy neutrino event on 22 September 2017 which was found to be coincident with a flaring blazar, TXS 0506+056. This first multi-messenger observation hinted at blazars being sources of observed astrophysical neutrinos and raised a need for extensive correlation studies to properly understand which blazars are neutrino sources. Here, we present a correlation analysis between 15GHz radio observations of active galactic nuclei reported in the MOJAVE XV catalog and IceCube detector data. We also discuss the implications of this analysis on the future of understanding the sources of astrophysical neutrinos using multi-messenger studies.

This recently described species is restricted to the isolated dune of San Luis Obispo County, California. It is pale powdery sandy brownish gray and has a pale elongate orbicular spot. Psammopolia sala occurs within the range of P. ochracea. The biserrate antenna (bipectinate in P. ochracea), can be used to identify males. Females are distinguished from all Psammopolia by a shorter ovipositor lobe (0.27× as long as the ductus bursae in P. sala; 0.40× in other species). Psammopolia sala is most similar in appearance and structure to P. insolens from central California. Males of P. sala have a smaller cucullus than P. insolens (0.7× valve width compared to 1.0× width for P. insolens). Th e length of the ovipositor described above distinguishes females. Distribution and biology. Psammopolia sala is restricted to the type locality where it flies over outer coastal dunes. It has been found in May and again in September and October.

Exploring the effect of Lorentz invariance violation with the currently running long-baseline experiments.

Year: 2020

description: Neutrinos can propagate very long distances without any deviation as they undergo only through weak interactions. This characteristic property can thus provide an ideal platform to investigate Planck suppressed physics, such as CPT violation, through their long distance propagation. CPT violation can be studied through Lorentz invariance violation (LIV) in the long-baseline neutrino oscillation experiments. Considering four-dimensional Lorentz violating parameters, we obtain the sensitivity limits on the LIV parameters from NO$\nu$A and T2K experiments. The sensitivity limits on LIV parameters obtained from T2K are much weaker than that of NO$\nu$A and the synergy of T2K and NO$\nu$A can improve these sensitivities. Also, we show their effects on mass hierarchy and CP violation sensitivities for NO$\nu$A experiment. The mass hierarchy and CPV sensitivities are either enhanced or deteriorated significantly, as they crucially depend on the CP-violating phases of LIV parameters.

description: We consider the height of random k-trees and k-Apollonian networks. These random graphs are not really trees, but instead have a tree-like structure. The height will be the maximum distance of a vertex from the root. We show that w.h.p. the height of random k-trees and k-Apollonian networks is asymptotic to c log t, where t is the number of vertices, and c = c(k) is given as the solution to a transcendental equation. The equations are slightly different for the two types of process. In the limit as k → ∞ the height of both processes is asymptotic to log t/(k log 2).

Production of DUNE anode plane assemblies
Creators: name: Prince, Sebastien
Publisher: name: Zenodo
Year: 2020

description: DUNE is an upcoming long-baseline neutrino-oscillation experiment, with one primary goal being the discovery of leptonic violation of the charge–parity symmetry. The far detector will be composed of four liquid-argon time-projection chambers, including two that will operate in a single argon phase. Anode plane assemblies are critical components in these single-phase detectors as they are responsible for sensing the drifting ionization electrons. Prototypes of these assemblies have been built internationally and have been operating in ProtoDUNE-SP at CERN since 2018. Improvements have been made in their design and production process following findings in their operation. The final-design assemblies will start being produced in the next months and will ultimately be tested in the upcoming ProtoDUNE-SP II.

description: We consider a three-dimensional kinetic model for a two species plasma consisting of electrons and ions confined by an external nonconstant magnetic field. Then we derive a kinetic-fluid model when the mass ratio $m_e/m_i$ tends to zero. Each species initially obeys a Vlasov-type equation and the electrostatic coupling follows from a Poisson equation. In our modeling, ions are assumed non-collisional while a Fokker-Planck collision operator is taken into account in the electron equation. As the mass ratio tends to zero we show convergence to a new system where the macroscopic electron density satisfies an anisotropic drift-diffusion equation. To achieve this task, we overcome some specific technical issues of our model such as the strong effect of the magnetic field on electrons and the lack of regularity at the limit. With methods usually adapted to diffusion limit of collisional kinetic equations and including renormalized solutions, relative entropy dissipation and velocity averages, we establish the rigorous derivation of the limit model.

description: Ο χρόνος που αφιερώνει κάποιος στην εργασία του είναι σημαντική παράμετρος για την επιλογή της. Το ίδιο σημαντικός είναι και ο ελεύθερος χρόνος που έχει ο εργαζόμενος για την ξεκούρασή του αλλά και την βελτιστοποίηση της ζωής «μετά τη δουλειά». Είναι επομένως η υπόσχεση του ελεύθερου χρόνου στη ζωή κάποιου μια επίσης βασική παράμετρος για την επιλογή εργασίας. Είναι αυτό που θα παρακινήσει τον εργαζόμενο να αποδώσει τα μέγιστα στην εργασία του ώστε να ανταμειφθεί με τον ελεύθερο χρόνο κατά τη διάρκεια του οποίου θα αφιερώσει χρόνο για τα πράγματα που θεωρεί σημαντικά, όπως είναι η οικογένεια, η αυτοβελτίωση, η άσκηση, η διασκέδαση. Η παρούσα έρευνα ξεκίνησε με τη βιβλιογραφική έρευνα των δύο μεταβλητών (του ελεύθερου χρόνου και της παρακίνησης) και τη μεταξύ τους σχέση.

description: Liquid Argon Time Projection Chambers (LArTPCs) are a class of detectors that produce high resolution images of charged particles within their sensitive volume. The identification and clustering of electromagnetic (EM) showers in LArTPCs is of central importance to the current and future neutrino physics program. EM activity typically exhibits spatially detached fragments of varying morphology and orientation that are challenging to efficiently assemble using traditional algorithms. Graphical Neural Networks (GNNs) were developed in recent years to find correlations between objects embedded in an arbitrary space. GNNs are studied with the goal of predicting the adjacency matrix of EM shower fragments and to identify the origin of showers, i.e. primary fragments. The energy resolution of the showers assembled with GNNs is presented and the reconstruction of the mass of neutral pions is used as a test case to further validate the algorithm.

Τα τελευταία χρόνια, όλο και περισσότερες εταιρείες φαίνεται να επενδύουν στο ανθρώπινο δυναμικό τους. Επίσης υπάρχουν πολλές έρευνες που δείχνουν ότι το μεγαλύτερο μέρος των εργαζομένων δεν τρέφονται σωστά, γεγονός που συμβάλει και στην απόδοση τους. Τα δύο αυτά στοιχεία δημιούργησαν την ανάγκη να γίνει η παρακάτω ανάλυση αλλά και να ελέγξουμε την πιθανή βιωσιμότητα μιας τέτοιας επιχειρηματικής ιδέας. Πιο συγκεκριμένα η white collar είναι μια επιχείρηση που θα παρέχει υγιεινά μαγειρευτά πιάτα σε πελάτες που εργάζονται στην ευρύτερη περιοχή στο δαχτυλίδι Αμαρουσίου. Σκοπός είναι να προσεγγίσουμε τις εταιρείες που εδρεύουν στη περιοχή και να δημιουργήσουμε συνεργασίες για την παροχή γευμάτων στο προσωπικό που διαθέτουν. Οι πελάτες θα μπορούν να γευματίζουν είτε στο χώρο της επιχείρησης είτε στον χώρο εργασίας τους. Η αισθητική του χώρου σε συνδυασμό με την εξυπηρέτηση και τις παροχές θα λειτουργούν με τέτοιο τρόπο που θα συμβάλουν θετικά στην αποδοτικότητα αλλά και στις δημιουργία σχέσεων εμπιστοσύνης των πελατών και των επιχειρήσεων που θα επενδύουν σε αυτούς. Στη μελέτη υπάρχει αναλυτικό πλάνο με τους στόχους, την αγορά αλλά και τους μεθόδους μάρκετινγκ που θα ακολουθήσει για να τα επιτύχει. Επίσης, έχει γίνει και αναλυτική καταγραφή τους μηχανολογικού και τεχνολογικού εξοπλισμού που θα χρειαστεί αλλά και των αναγκών σε ανθρώπινο δυναμικό.

description: In this poster, we present a fast and scalable deep learning algorithm for particle clustering in liquid argon time projection chamber (LArTPC) data, as part of the machine learning based reconstruction effort at SLAC. Particle clustering refers to the task of grouping image pixels into particle instances, which is regarded as one of the most challenging tasks in LArTPC data reconstruction. Building on previous works on sparse convolutional neural networks and proposal free instance segmentation, we build an end-to-end trainable particle clustering deep neural network that can learn an embedding of the image pixels to perform point cloud clustering in a transformed space. Using 3D images of LArTPC open dataset, we evaluate the network's purity and efficiency of cluster assignments and assess its overall computing resource usage. The proposed algorithm is applicable to data reconstruction of 2D and 3D imaging LArTPC detectors, including DUNE and SBN programs.

description: We report the results of neutron scattering on a powder sample of Gd3Ga5O12 at high magnetic fields. We find that in high fields (B>1.8 T) the system is not fully polarized, but has a small canting of the moments induced by the dipolar interaction. We show that the degree of canting is accurately predicted by the standard Hamiltonian which includes the dipolar interaction. The inelastic scattering is dominated at large momentum transfers by a band of almost dispersionless excitations. We show that these correspond to the spin waves localized on ten site rings, expected for a system described by a nearest neighbor interaction, and that the spectrum at high fields B>1.8 T is well-described by a spin wave theory. The phase for fields <1.8 T is characterized by an antiferromagnetic Bragg peak at (210) and an incommensurate peak.

The Complexity of Phylogeny Constraint Satisfaction Problems

description: We systematically study the computational complexity of a broad class of computational problems in phylogenetic reconstruction. The class contains for example the rooted triple consistency problem, forbidden subtree problems, the quartet consistency problem, and many other problems studied in the bioinformatics literature. The studied problems can be described as \emph{constraint satisfaction problems} where the constraints have a first-order definition over the rooted triple relation. We show that every such phylogeny problem can be solved in polynomial time or is NP-complete. On the algorithmic side, we generalize a well-known polynomial-time algorithm of Aho, Sagiv, Szymanski, and Ullman for the rooted triple consistency problem. Our algorithm repeatedly solves linear equation systems to construct a solution in polynomial time. We then show that every phylogeny problem that cannot be solved by our algorithm is NP-complete. Our classification establishes a dichotomy for a large class of infinite structures that we believe is of independent interest in universal algebra, model theory, and topology. The proof of our main result combines results and techniques from various research areas: a recent classification of the model-complete cores of the reducts of the homogeneous binary branching C-relation, Leeb's Ramsey theorem for rooted trees, and universal algebra.

Thresholds for Extreme Orientability

description: Multiple-choice load balancing has been a topic of intense study since the seminal paper of Azar, Broder, Karlin, and Upfal. Questions in this area can be phrased in terms of orientationsof a graph, or more generally a k-uniform random hypergraph. A (d,b)-orientation is an assignment of each edge to d of its vertices, such that no vertex has more than b edges assigned to it. Conditions for the existence of such orientations have been completely documented except for the “extreme” case of (k−1,1)-orientations. We consider this remaining case, and establish:

The density threshold below which an orientation exists with high probability, and above which it does not exist with high probability.

An algorithm for finding an orientation that runs in linear time with high probability, with explicit polynomial bounds on the failure probability.

Previously, no closed-form expression for the threshold was known. The only known algorithms for constructing (k−1,1)-orientations worked for k≤3, and were only shown to haveexpected linear running time.
Muon neutrinos and antineutrinos disappearance analysis from T2K
Creators: name: Stephane Zsoldos
Publisher: name: Zenodo
Year: 2020

description: T2K is an experiment designed to observe neutrino oscillations with a baseline of 295 km across Japan from the J-PARC accelerator complex to the Super-Kamiokande detector. Its main goal is to measure oscillation parameters though $\nu_\mu$ disappearance and $\nu_e$ appearance. Recently, T2K excluded values of $\delta_\text{CP}$ at $3\sigma$ confidence for the first time. I will present two analyses studying for the disappearance of muon neutrinos and antineutrinos, using samples of muon-like events recorded by the T2K experiment. The first analysis uses the conventional PMNS model, to extract the parameters $\theta_{23}$ and $\Delta m^2_{32}$ using two separate parametrization for neutrinos and antineutrinos, testing CPT compatibility and any unconventional matter effect. The second analysis uses a a 'two-flavour' oscillation model allowing $\sin^2\left(\theta_{23}\right)>1$, allowing the oscillation probability to go beyond PMNS and test its consistency.

Typical examples may be found in cavitation and related theories. Standard techniques cannot be used due to the gap between the exponent q of the growth condition and the exponent p of integrability of the macroscopic strain [delta inverse]u. A recently introduced global method for relaxation and fine Sobolev trace and extension theorems are applied."

description: Machine learning applications in fields where data is sensitive, such as healthcare and banking, face challenges due to the need to protect the privacy of participating users. Tools developed in the past decades that aim to address this challenge include differential privacy and federated learning. Yet maintaining performance while protecting sensitive data poses a trilemma between accuracy, privacy, and efficiency. In this thesis, we aim to address these fundamental challenges and take a step towards enabling machine learning under privacy and resource constraints. On the differential privacy front, we develop in Chapter 2 an algorithm that addresses efficiency and accuracy of differentially private empirical risk minimization. We provide a dimension independent excess risk bound and show the algorithm converges to this excess risk bound at the same rate as AdaGrad. In Chapter 3 we introduce an algorithm for differentially private Top-k selection, a problem that often arises as a building block of large-scale data analysis tasks like NLP and recommender systems. The algorithm samples from a distribution with exponentially large support only in polynomial time and space, and improves existing pure differential privacy methods. On the federated learning front, locality of data imposes various system design challenges due to resource constraints. In Chapter 4, we propose federated and differentially private algorithms for matrix factorization tasks that arise when training recommender systems in the settings where data is distributed across different silos (e.g., hospitals or banks). Chapter 5 introduces a client selection strategy that reduces communication in federated learning while maintaining accuracy of the model. Finally, in Chapter 6 we conclude by presenting F3AST, a novel algorithm that addresses user intermittency in federated learning under an unknown and time varying system configuration.
