description: Despite the recent progress towards efficient multiple kernel learning (MKL), the structured output case remains an open research front. Current approaches involve repeatedly solving a batch learning problem, which makes them inadequate for large scale scenarios. We propose a new family of online proximal algorithms for MKL (as well as for group-LASSO and variants thereof), which overcomes that drawback. We show regret, convergence, and generalization bounds for the proposed method. Experiments on handwriting recognition and dependency parsing testify for the successfulness of the approach.

description: NOTCH1 mutant clones occupy the majority of normal human esophagus by middle age but are comparatively rare in esophageal cancers, suggesting NOTCH1 mutations drive clonal expansion but impede carcinogenesis. Here we test this hypothesis. Sequencing NOTCH1 mutant clones in aging human esophagus reveals frequent biallelic mutations that block NOTCH1 signaling. In mouse esophagus, heterozygous Notch1 mutation confers a competitive advantage over wild-type cells, an effect enhanced by loss of the second allele. Widespread Notch1 loss alters transcription but has minimal effects on the epithelial structure and cell dynamics. In a carcinogenesis model, Notch1 mutations were less prevalent in tumors than normal epithelium. Deletion of Notch1 reduced tumor growth, an effect recapitulated by anti-NOTCH1 antibody treatment. Notch1 null tumors showed reduced proliferation. We conclude that Notch1 mutations in normal epithelium are beneficial as wild-type Notch1 favors tumor expansion. NOTCH1 blockade may have therapeutic potential in preventing esophageal squamous cancer.

description: We derive formulas and algorithms for Kitaev's invariants in the periodic table for topological insulators and superconductors for finite disordered systems on lattices with boundaries. We find that K-theory arises as an obstruction to perturbing approximately compatible observables into compatible observables. We derive formulas in all symmetry classes up to dimension two, and in one symmetry class in dimension three, that can be computed with sparse matrix algorithms. We present algorithms in two symmetry classes in 2D and one in 3D and provide illustrative studies regarding how these algorithms can detect the scaling properties of phase transitions.

Apuleius, Metamorphosen – eine Eselei in der Schule?

Year: 2023

description: Die Metamorphosen des Apuleius sind eines der wirkmächtigsten literarischen Werke der Antike und gehören zur Weltliteratur. Im Lateinunterricht der Schule werden sie bislang nicht gelesen. Der Beitrag fordert genau dies ein, damit der Lateinunterricht auf die Anforderungen der Gegenwart – das Leben in einer zunehmend von Diversität geprägten und Werte immer wieder in Frage stellenden Gesellschaft – antworten kann. Der Beitrag gliedert sich in drei Teile: 1. Warum ist Apuleius wichtig? Es gibt fachliche, didaktische und pädagogische Argumente dafür, dass Apuleius literaturdidaktisch in der Schule gelesen werden soll. 2. Was kann man mit Apuleius in der Schule machen? Der Text ist ein Entwicklungsroman für Jugendliche, thematisiert mit Vielfalt, Interkulturalität, der Einnahme der Perspektive des Tieres und mit Interreligiosität aktuelle Herausforderungen. Literarisch bietet er durch die systematische Destabilisierung des Lesers und durch den distanzierenden Witz ein einmaliges literarisches Bildungserlebnis. 3. Die Folgen für den Lateinunterricht: Die Lektüre des Apuleius stellt neue Herausforderungen und verändert den Lateinunterricht bis hin zur Lehrbuchphase. Wenn man einen Autor wie Apuleius und vergleichbare Literatur lesen will, dann müssen von Anfang an andere Schwerpunkte im Bereich Wortschatz und Themen gesetzt werden, als es aktuell der Fall ist. Die Kanonfrage des Lateinunterrichtes erstreckt sich damit bis zur ersten Lektion des Lehrbuches. Auch die Rolle der Schüler*innen ändert sich, denn der*die literarisch lesende Schüler*in braucht eine hohe Selbstständigkeit im Umgang mit den Texten.

description: We investigate the nature of the Alfvénic turbulence cascade in two fluid MHD simulations in order to determine if turbulence is damped once the ion and neutral species become decoupled at a critical scale called the ambipolar diffusion scale (L$_{AD}$). Using mode decomposition to separate the three classical MHD modes, we study the second order structure functions of the Alfvén mode velocity field of both neutrals and ions in the reference frame of the local magnetic field. On scales greater than L$_{AD}$ we confirm that two fluid turbulence strongly resembles single fluid MHD turbulence. Our simulations show that the behavior of two fluid turbulence becomes more complex on scales less than L$_{AD}$. We find that Alfvenic turbulence can exist past L$_{AD}$ when the turbulence is globally super-Alfvénic, with the ions and neutrals forming separate cascades once decoupling has taken place. When turbulence is globally sub-Alfvenic and hence strongly anisotropic with a large separation between the parallel and perpendicular decoupling scales, turbulence is damped at L$_{AD}$. We also find that the power spectrum of the kinetic energy in the damped regime is consistent with a $k^{-4}$ scaling (in agreement with the predictions of Lazarian, Vishniac & Cho 2004).

description: Fragen des Forschungsdatenmanagements in die Hochschullehre...
 ...statt einer Einführung: Gedanken zur Verortung von Dimensionen des des Forschungsdatenmanagements halten seit einiger Zeit Einzug in die Hochschullehre, sei es als eigenständiger Studiengang, als Zertifikat oder als Bestandteil eines Moduls (siehe etwa den Überblick in Gantert, Neher & Schade 2018 sowie allgemeiner zu Fragen der ‚data literacy‘ Heidrich, Bauer & Krupka 2018). Das Interesse an diesen Fragen ist vor allem in bibiothekswissenschaftlicher Lehre vertreten, noch nicht breiter diskutiert ist die Thematisierung im Rahmen fachwissenschaftlicher Lehrveranstaltungen geisteswissenschaftlicher (nicht expliziter Digital Humanities) Studiengänge, die sowohl im Rahmen einzelner Sitzungen als auch als eigene Lehrveranstaltung denkbar ist. Die nachstehenden Ausführungen illustrieren das Vorgehen im Rahmen einer Lehrveranstaltung, die sich an Studierende der germanistischen und allgemeinen Sprachwissenschaft richtet. Unter dem Stichwort ‚Linguistische Empirie‘ ist der Beschäftigung mit methodologischen Fragen in den fachspezifischen Bestimmungen beider Studiengänge innerhalb der geisteswissenschaftlichen Fakultät der Universität Hamburg systematisch verankert. Konzeptuell sind diese Lehrveranstaltungen den Grundsätzen ‚forschenden Lernens‘ verpflichtet. Dabei geht es darum, wie etwa Huber (2009:11) ausführt, dass Studierende den „Prozess eines Forschungsvorhabens von der Entwicklung der Fragen und Hypothesen über die Wahl und Ausführung der Methoden bis zur Prüfung und Darstellung der Ergebnisse in selbständiger Arbeit oder in aktiver Mitarbeit in einem übergreifenden Projekt (mit)gestalten, erfahren und reflektieren.“. Auch wenn dieser Prozess nicht in allen Teilen gleichwertig in Lehrveranstaltungen unterzubringen, sondern immer eine Auswahl zu treffen ist, bietet die hochschuldidaktische Lehre, die sich am forschenden Lernen orientiert, bereits in der Aufbauphase des fachwissenschaftlichen Studiums einen zentralen Mehrwert: Ausgehend von Grundkenntnissen über Kernkonzepte und Einheiten einer professionellen Sprachbetrachtung besteht die Möglichkeit im Rahmen einer methodologisch und mit Blick auf den Umgang mit Forschungsdaten konzentrierten Lehrveranstaltung die Dynamik von Sprache in ihrem Gebrauch sowie die Erprobung kategorieller Zugriffe unter Maßgabe einer die Studiereden interessierenden Frage zu erproben und zu routinisieren. Damit werden Kenntnisse sowohl für das weiterführende Fachstudium als auch fachübergreifende Kompetenzen im Bereich der ‚data literacy‘ vermittelt und Ansatzpunkte möglicher Vertiefungen aufgezeigt

description: The artificial source of antineutrinos 144Ce-144Pr is one of the most promising for the sterile neutrino search experiments. We have produced a semiconductor $\beta$-spectrometer with a sensitive region thickness exceeding 9.6 mm that fully absorbs electrons with energy below 3 MeV. It was used for a precise measurement of the $\beta$-spectra of 144Ce-144Pr ground and excited state transitions. The measured spectral shapes correspond to theoretical expectations. This result was used in simulation of scintillator detector experiments with the Monte-Carlo method within GEANT4 for estimation of the sensitivity to sterile neutrino with 144Ce-144Pr antineutrino source and a large scintillation detector. The best sensitivity curves have been obtained for the cylindrical detector geometry for the detector mass of 100 tones. We can estimate that such detector and a source with activity of 100 kCi fully covers the reactor neutrino anomaly at 90% C.L.

description: We present measurements of bias triangles in several biasing configurations. Thorough analysis of the data allows us to present data from all four possible bias configurations on a single plot in chemical potential space. This presentation allows comparison between different biasing directions to be made in a clean and straightforward manner. Our analysis and presentation will prove useful in demonstrations of Pauli-spin blockade where comparisons between different biasing directions are paramount. The long term stability of the CMOS compatible Si/SiO2 only architecture leads to the success of this analysis. We also propose a simple variation to this analysis that will extend its use to systems lacking the long term stability of these devices.

description: Die Auswahl der im schulischen Lateinunterricht zu lesenden Lektüre unterliegt häufig der Obligatorik ministerieller Vorgaben in Form von Lehrplänen und Vorgaben für das Zentralabitur. Zugleich soll Ziel aller unterrichtlichen Bemühungen sein, Schüler*innen auf ihrem Weg zur Mündigkeit bzw. Autonomie zu unterstützen. In diesem Beitrag wird verdeutlicht, dass ein interdisziplinär arrangierter Lateinunterricht die Metakompetenzen des begründeten und reflektierenden Urteilens dahingehend fördert, sich kritisch-konstruktiv mit der zu lesenden Lektüre – unter dem Fokus auf eine Problemorientierung – auseinanderzusetzen. Zugleich weist dies vice versa nach, dass eine Orientierung an Metakompetenzen ein wichtiges Kriterium für die Lektüreauswahl sein kann. Dass gemäß konventioneller Vorgaben Literatur im Unterricht thematisiert wird, die nicht den Interessen und Bedürfnissen der Schüler*innen entspricht, scheint zumindest dann problematisch zu sein, wenn ihnen der Weg zur Partizipation als Stufe der Mündigkeit gänzlich verwehrt werden sollte. Eine fächerübergreifende Lektüre ermöglicht das Denken über die Fachgrenzen hinaus und eröffnet damit sowohl für die Lehrenden als auch für die Schüler*innen Möglichkeiten, Texte zu lesen, die nicht kanonisch sind, aber kritisch mit Problemen konfrontieren, die von gegenwärtig subjektiver Relevanz sind. Gleichzeitig heißt dies nicht, dass nicht auch kanonische Literatur ausgewählt werden kann, um dem Problem sprachlich und historisch nachzuspüren. Vor diesem Hintergrund ermöglicht die Orientierung an Metakompetenzen und der critical literacy, Literatur ausgehend von einem für die Schüler*innen relevanten Problem der Gegenwart analytisch zu hinterfragen, um die eigene Urteilskompetenz fallbezogen zu schärfen.

description: Undirected graphical models are important in a number of modern applications that involve exploring or exploiting dependency structures underlying the data. For example, they are often used to explore complex systems where connections between entities are not well understood, such as in functional brain networks or genetic networks. Existing methods for estimating structure of undirected graphical models focus on scenarios where each node represents a scalar random variable, such as a binary neural activation state or a continuous mRNA abundance measurement, even though in many real world problems, nodes can represent multivariate variables with much richer meanings, such as whole images, text documents, or multi-view feature vectors. In this paper, we propose a new principled framework for estimating the structure of undirected graphical models from such multivariate (or multi-attribute) nodal data. The structure of a graph is inferred through estimation of non-zero partial canonical correlation between nodes. Under a Gaussian model, this strategy is equivalent to estimating conditional independencies between random vectors represented by the nodes and it generalizes the classical problem of covariance selection (Dempster, 1972). We relate the problem of estimating non-zero partial canonical correlations to maximizing a penalized Gaussian likelihood objective and develop a method that efficiently maximizes this objective. Extensive simulation studies demonstrate the effectiveness of the method under various conditions. We provide illustrative applications to uncovering gene regulatory networks from gene and protein profiles, and uncovering brain connectivity graph from positron emission tomography data. Finally, we provide sufficient conditions under which the true graphical structure can be recovered correctly.
Exact solitons and manifold mixing dynamics in the spin-orbit-coupled spinor condensates

description: We derive exact static as well as moving solitonic solutions to the one-dimensional spin-orbit-coupled F=1 Bose-Einstein condensates. The static polar soliton is shown to be the ground state by the imaginary-time evolution method. It shows a helical modulation of the order parameter due to the spin-orbit coupling. In particular, the moving soliton exhibits a periodic oscillation among the particle numbers of the hyperfine states. We further explore the temporal evolution of the static polar soliton and find that the spin-polarization exhibits dynamical oscillations. This disappearance and re-emergence of the ferromagnetic state indicates the mixing of the ferromagnetic and the antiferromagnetic manifolds.

Search for exotic neutrino interactions using solar neutrinos in XMASS-I
Creators: name: Ogawa, Hiroshi
Publisher: name: Zenodo
Year: 2020

description: We have searched for exotic neutrino-electron interactions that could be produced by a neutrino millicharge, magnetic moment or dark photons using solar neutrinos in the XMASS-I. No significant signals have been observed and upper limit of these constant values are estimated as preliminary. For the neutrino millicharge search, $5.4\times10^{-11}$e for all flavors of neutrino is obtained. We also set individual flavors to be $7.3\times10^{-12}e$ for $\nu_e$, $1.1\times10^{-11}e$ for $\nu_{\mu}$, and $1.1\times10^{-11}e$ for $\nu_{\tau}$. These limits ate the most stringent yet obtained from direct measurements. For the neutrino magnetic moment search, $1.8\times10^{-10}\mu_{B}$ is obtained. In addition, we obtain upper limits for the coupling constant of dark photons and almost exclude the possibility to understand the muon $g-2$ anomaly by dark photons.

description: Hypersonic velocities, usually characterised by more than five times the speed of sound, have been regularly attained in typical re-entry profiles. More recent developments in the field of air-breathing hypersonic propulsion can lead to the expectation of larger atmospheric vehicles routinely reaching these velocities within the next few decades. A common problem of these systems is the thermal management, specifically of the leading edge, which is required to be thin to reduce aerodynamic drag. This leads to high values of heat flux around the stagnation point.1 Ultra-High Temperature Ceramics (UHTC) are normally used to withstand such an environment. However, these materials are limited in flight duration and Mach regime. Recent advances in its formalisation, modelling and testing motivate considering Electron Transpiration Cooling (ETC) as a potential solution for the heat management problem around sharp aerodynamic surfaces. This strategy is based on thermionic emission of electrons from the hot leading edge towards colder aft-body elements, thus distributing the energy over a bigger surface. This common principle occurs for all thermionic materials with low-enough work function but it would present a weak impact if these electrons were accumulated near the surface due to the presence of a space charge close to the wall. This limit can however be overcome through the application of an external electric field, allowing further electrons to be emitted, carrying with them energy away from the hot leading edge. To complete the cycle of heat redistribution and ensure no further space charging limit occurs elsewhere on the surface, the electrons reattach to the wing downstream, and travel back upstream through an electrical circuit that reintroduces them at the leading edge, thereby inducing a current. The present work aims at assessing how to measure physical quantities that relate to ETC phenomena. This is carried out through a test campaign in the Plasmatron facility at the Von Karman Institute, which allows reaching high surface temperatures under flows stagnating on candidate samples. Graphite samples (work function of 4.7 eV) were tested and found to emit currents between 0.05 to 0.1 A when heated with Nitrogen plasma flow, seemingly following theoretical predictions for the lower temperature ranges of 2000 to 2250 degrees celsius.
On the Black Hole Masses In Ultra-luminous X-ray Sources

description: Ultra-luminous X-ray sources (ULXs) are off-nuclear X-ray sources in nearby galaxies with X-ray luminosities $\geq$ 10$^{39}$ erg s$^{-1}$. The measurement of the black hole (BH) masses of ULXs is a long-standing problem. Here we estimate BH masses in a sample of ULXs with XMM-Newton observations using two different mass indicators, the X-ray photon index and X-ray variability amplitude based on the correlations established for active galactic nuclei (AGNs). The BH masses estimated from the two methods are compared and discussed. We find that some extreme high-luminosity ($L_{\rm X} >5\times10^{40}$ erg s$^{-1}$) ULXs contain the BH of 10$^{4}$-10$^{5}$ $M_\odot$. The results from X-ray variability amplitude are in conflict with those from X-ray photon indices for ULXs with lower luminosities. This suggests that these ULXs generally accrete at rates different from those of X-ray luminous AGNs, or they have different power spectral densities of X-ray variability. We conclude that most of ULXs accrete at super-Eddington rate, thus harbor stellar-mass BH.

description: Fine structures in the tunneling spectra of superconductors have been widely used to identify fingerprints of the interaction responsible for Cooper pairing. Here we show that for scanning tunneling microscopy (STM) of Pb, the inclusion of inelastic tunneling processes is crucial for the proper interpretation of these fine structures. For STM the usual McMillan inversion algorithm of tunneling spectra must therefore be modified to include inelastic tunneling events, an insight that is crucial for the identification of the pairing glue in conventional and unconventional superconductors alike.

description: Blazar hadronic models have been developed in the past decades as an alternative to leptonic ones. In hadronic models the gamma-ray emission is associated with synchrotron emission by protons, and/or secondary leptons produced in proton-photon interactions. Together with photons, hadronic emission models predict the emission of neutrinos that are therefore the smoking gun for acceleration of relativistic hadrons in blazar jets. The simulation of proton-photon interactions and all associated radiative processes is a complex numerical task, and different approaches to the problem have been adopted in the literature. So far, no systematic comparison between the different codes has been performed, preventing a clear understanding of the underlying uncertainties in the numerical simulations. To fill this gap, we have undertaken the first comprehensive comparison of blazar hadronic codes, and the first results from this effort will be presented in this contribution.

description: We study the Josephson coupling of superconducting (SC) islands through the surface of single-layer (SLG) and bilayer (BLG) graphene, as a function of distance between the grains, temperature, chemical potential and external (transverse) gate-voltage. For SLG, we provide a comparison with existing literature. The proximity effect is analyzed through a Matsubara Green function approach. This represents the first step in a discussion of the conditions for the onset of a granular superconductivity within the film, made possible by Josephson currents flowing between superconductors. To ensure phase coherence over the 2D sample, a random spatial distribution can be assumed for the SC islands on the SLG sheet (or intercalating the BLG sheets). The tunable gate-voltage-induced band gap of BLG affects the asymptotic decay of the Josephson coupling-distance characteristic for each pair of SC islands in the sample, which results in the end in a qualitatively strong field-dependence of the relation between Berezinskii-Kosterlitz-Thouless transition critical temperature and gate-voltage.

description: Reconstruction and monitoring of displacement and strain fields is an important problem in engineering. We analyze the remote and non-obtrusive methods of strain measurement based on photogrammetry and Digital Image Correlation (DIC). The method is based on covering the photographed surface with a pattern of speckles and comparing the images taken before and after the deformation. In this study, a comprehensive literature review and comparative analysis of photogrammetric solutions is presented. The analysis is based on a specially developed Digital Image Synthesizer To Reconstruct Strain in Solids (DISTRESS) Simulator to generate synthetic images of displacement and stress fields in order to investigate the intrinsic accuracy of the existing variants of DIC. We investigated the Basic DIC and a commercial software VIC 2D, both based on displacement field reconstruction with post processing strain determination based on numerical differentiation. We also investigated what we call the Extended DIC where the strain field is determined independently of the displacement field. While the Basic DIC and VIC 2D are faster, the Extended DIC delivers the best accuracy of strain reconstruction. The speckle pattern is found to be playing a critical role in achieving high accuracy for DIC. Increase in subset size for DIC does not significantly improves the accuracy, while the smallest subset size depends on the speckle pattern and speckle size. Increase in the overall image size provides more details but does not play significant role in improving the accuracy, while significantly increasing the computation cost.

description: A measurement of dijet correlations in p-Pb collisions at $\sqrt{s_{\rm NN}}=5.02$ TeV with the ALICE detector is presented. Jets are reconstructed from charged particles measured in the central tracking detectors and neutral energy deposited in the electromagnetic calorimeter. The transverse momentum of the full jet (clustered from charged and neutral constituents) and charged jet (clustered from charged particles only) is corrected event-by-event for the contribution of the underlying event, while corrections for underlying event fluctuations and finite detector resolution are applied on an inclusive basis. A projection of the dijet transverse momentum, $k_{\rm Ty} = p_\rm{T,jet}^\rm{ch+ne} \; \rm{sin}(Δφ_{\rm{dijet}})$ with $Δφ_{\rm{dijet}}$ the azimuthal angle between a full and charged jet and $p_\rm{T,jet}^\rm{ch+ne}$ the transverse momentum of the full jet, is used to study nuclear matter effects in p-Pb collisions. This observable is sensitive to the acoplanarity of dijet production and its potential modification in p-Pb collisions with respect to pp collisions. Measurements of the dijet $k_{\rm Ty}$ as a function of the transverse momentum of the full and recoil charged jet, and the event multiplicity are presented. No significant modification of $k_{\rm Ty}$ due to nuclear matter effects in p-Pb collisions with respect to the event multiplicity or a PYTHIA8 reference is observed.

description: We complement our previous analysis of a sample of z~1-2 luminous and ultra-luminous infrared galaxies ((U)LIRGs), by adding deep VLA radio observations at 1.4 GHz to a large data-set from the far-UV to the sub-mm, including Spitzer and Herschel data. Given the relatively small number of (U)LIRGs in our sample with high S/N radio data, and to extend our study to a different family of galaxies, we also include 6 well sampled near IR-selected BzK galaxies at z~1.5. From our analysis based on the radiative transfer spectral synthesis code GRASIL, we find that, while the IR luminosity may be a biased tracer of the star formation rate (SFR) depending on the age of stars dominating the dust heating, the inclusion of the radio flux offers significantly tighter constraints on SFR. Our predicted SFRs are in good agreement with the estimates based on rest-frame radio luminosity and the Bell (2003) calibration. The extensive spectro-photometric coverage of our sample allows us to set important constraints on the SF history of individual objects. For essentially all galaxies we find evidence for a rather continuous SFR and a peak epoch of SF preceding that of the observation by a few Gyrs. This seems to correspond to a formation redshift of z~5-6. We finally show that our physical analysis may affect the interpretation of the SFR-M* diagram, by possibly shifting, with respect to previous works, the position of the most dust obscured objects to higher M* and lower SFRs.

Life, death, and after life: a workshop on things
Creators: name: Özçetin, Seda
Publisher: name: Zenodo
Year: 2021
Subjects: fluid assemblages
things

description: In Changing Things, Redström and Wiltse (2019) talk about how things have changed in their becoming throughout the history bringing us to the time of fluid assemblages. These dynamic beings have created new spatio-temporal ecologies. This moment looks at fluid assemblages and their impact in DRS community’s everyday lives. What kinds of things have emerged at our homes or workplaces (Life), what kinds of things have disappeared (Death), what kinds of things do we still keep but not use or have we repurposed (After Life)? What caused these transitions? How is our relationship with these things, how do we feel about them, what has changed? The moment invites the DRS community to create collages reflecting on these experiences by focusing on a selection of daily activities as listening to music, doing sports, cooking, maintaining wellbeing, etc. on a collective Miro board.
Once upon a time, there was a Terms of Service: a presentation and workshop on real and fictional ToS stories

storytelling

description: According to different online sources, an average person has between 40 to 60 apps installed on their smart phones in 2021, meaning an average person has likely agreed to 40 to 60 terms of services (ToS). While it has become a common practice to just accept the terms without reading, we have also started to see an emergence of consciousness regarding the ToS. Some of us in fact read, try to read, accept, reject, think or ask questions about ToSs after reading them. This moment aims to collect stories about our interactions with the ToSs, the experiences that had an impact on our lives, perspectives, interactions with things, services, or people, as well as the ToSs we dream of or want to speculate about. So, the moment will collect reflections on the real and the fiction.

Mass of Y(3940) in Bethe-Salpeter equation for quarks

description: The general form of the Bethe-Salpeter wave functions for the bound states composed of two vector fields of arbitrary spin and definite parity is corrected. Using the revised general formalism, we investigate the observed \emph{Y}(3940) state which is considered as a molecule state consisting of $D^{*0}\bar{D}^{*0}$. Though the attractive potential between $D^{*0}$ and $\bar{D}^{*0}$ including one light meson ($σ$, $π$, $ω$, $ρ$) exchange is considered, we find that in our approach the contribution from one-$π$ exchange is equal to zero and consider SU(3) symmetry breaking. The obtained mass of \emph{Y}(3940) is consistent with the experimental value.

Optimal rates for stochastic convex optimization under Tsybakov noise condition

description: We focus on the problem of minimizing a convex function f over a convex set S given T queries to a stochastic first order oracle. We argue that the complexity of convex minimization is only determined by the rate of growth of the function around its minimum x∗f,S, as quantified by a Tsybakov-like noise condition. Specifically, we prove that if fgrows at least as fast as ∥x−x∗f,S∥κ around its minimum, for some κ>1, then the optimal rate of learning f(x∗f,S) isΘ(T−κ/2κ−2). The classic rate Θ(1/T√) for convex functions and Θ(1/T) for strongly convex functions are special cases of our result for κ→∞ and κ=2, and even faster rates are attained for 1
Hadronization Tuning with GENIE v3.
Creators: name: Vidal, Julia Tena
Publisher: name: Zenodo
Year: 2020

description: The next generation of neutrino oscillation experiments rely on the precise understanding of neutrino interactions in a wide energy range. In particular, the knowledge of the exact mixture of hadrons in showers affects the efficiency to distinguish between NC/CC events, the topological characterization, and impacts the estimation of backgrounds. The GENIE neutrino Monte Carlo developed an effective low-mass hadronization model, known as AGKY, which incorporates PYTHIA events at high invariant mass. Only the low-AGKY model parameters were extracted from neutrino hadroproduction data. Moreover, comparisons of the GENIE model against an expanded and carefully curated archive of neutrino-induced hadron shower data exposed disagreements between different datasets, which further deteriorates at the PYTHIA region. The GENIE Collaboration aims to address this issue by tuning the hadronization model against all the available charged multiplicity bubble chamber data, providing the first uncertainty estimation for the GENIE hadronization model.

description: Low-dimensional embedding, manifold learning, clustering, classification, and anomaly detection are among the most important problems in machine learning. Here we consider the setting where each instance of the inputs corresponds to a continuous probability distribution. These distributions are unknown to us, but we are given some i.i.d. samples from each of them. While most of the existing machine learning methods operate on points, i.e. finite-dimensional feature vectors, in our setting we study algorithms that operate on groups, i.e. sets of feature vectors. For this purpose, we propose new nonparametric, consistent estimators for a large family of divergences and describe how to apply them for machine learning problems. As important special cases, the estimators can be used to estimate R´enyi, Tsallis, Kullback-Leibler, Hellinger, Bhattacharyya distance, L2 divergences, and mutual information. We present empirical results on synthetic data, real word images, and astronomical data sets.
The CROSS experiment: rejecting surface events with PSD
Creators: name: Hawraa Khalife
Publisher: name: Zenodo
Year: 2020

description: Neutrinoless double beta decay is a hypothetical rare nuclear transition. Its observation would provide an insight about the nature of neutrinos (Dirac or Majorana particle) demonstrating lepton number violation. This decay can be investigated with bolometers embedding the double beta decay isotope. The possibility to investigate this rare process is strongly influenced by the background level in the region of interest. The CROSS project (Cryogenic Rare event Observatory with Surface Sensitivity) aims at the development of bolometers capable of discriminating the background from surface alpha and beta interactions by exploiting the properties of superconducting Al film or normal metal Pd film deposited on crystal faces (Li2MoO4 and TeO2). These films work as pulse shape modifiers. The results of the tests on prototypes performed at IJCLab (Orsay, France) showed the capability of a few-µm (nm)-thick Al (Pd) film deposited on the crystal surface to discriminate surface from bulk events.
