GEAR-RT: Towards Exa-Scale Moment Based Radiative Transfer For Cosmological Simulations Using Task-Based Parallelism And Dynamic Sub-Cycling with SWIFT
Creators: name: Ivkovic, Mladen
Publisher: name: arXiv
Year: 2023
Subjects: subject: Instrumentation and Methods for Astrophysics (astro-ph.IM)
subject: FOS: Physical sciences

description: The development and implementation of GEAR-RT, a radiative transfer solver using the M1 closure in the open source code SWIFT, is presented, and validated using standard tests for radiative transfer. GEAR-RT is modeled after RAMSES-RT (Rosdahl et al. 2013) with some key differences. Firstly, while RAMSES-RT uses Finite Volume methods and an Adaptive Mesh Refinement (AMR) strategy, GEAR-RT employs particles as discretization elements and solves the equations using a Finite Volume Particle Method (FVPM). Secondly, GEAR-RT makes use of the task-based parallelization strategy of SWIFT, which allows for optimized load balancing, increased cache efficiency, asynchronous communications, and a domain decomposition based on work rather than on data. GEAR-RT is able to perform sub-cycles of radiative transfer steps w.r.t. a single hydrodynamics step. Radiation requires much smaller time step sizes than hydrodynamics, and sub-cycling permits calculations which are not strictly necessary to be skipped. Indeed, in a test case with gravity, hydrodynamics, and radiative transfer, the sub-cycling is able to reduce the runtime of a simulation by over 90%. Allowing only a part of the involved physics to be sub-cycled is a contrived matter when task-based parallelism is involved, and is an entirely novel feature in SWIFT. Since GEAR-RT uses a FVPM, a detailed introduction into Finite Volume methods and Finite Volume Particle Methods is presented. In astrophysical literature, two FVPM methods are written about: Hopkins (2015) have implemented one in their GIZMO code, while the one mentioned in Ivanova et al. (2013) isn't used to date. In this work, I test an implementation of the Ivanova et al. (2013) version, and conclude that in its current form, it is not suitable for use with particles which are co-moving with the fluid, which in turn is an essential feature for cosmological simulations.

description: PPT presentation and hand out of my Surrey talk, 2 February 2023.

 

Ever since the rise of mass publishing during the eighteenth century, the readers' curiosity has demanded to find satisfaction in associating an author's face with their work. The presence of illustrated frontispieces is only one among many manifestations of this desire to give a material body and a face to the authors of fiction. Author portraiture contributed considerably to what was quickly to become a true celebrity market. In her talk, Francesca Saggini will retrace the cultural and economic elements of visual authorship by taking Frances Burney as her case study. Francesca's journey of literary detection will find an amazing, and truly unexpected, conclusion in Surrey. Which face for Frances? We will all be invited to take our pick from the gallery of pictures illustrating this talk.

description: HE0450-2958, an interacting quasar-starburst galaxy pair at $z$ = 0.285, is one of the best known examples of strong star formation activity in the presence of a quasar-driven jet. We present new multi-band JVLA-imaging covering 1 to 6 GHz and reaching an angular resolution of up to $0{}_{{}^.}^{"}6$ (a 6-fold improvement over existing radio data). We confirm the previous detection of a spatially extended radio component around the quasar indicating that there is on-going star formation activity in the quasar host galaxy. For the first time, we directly detect a jet-like bipolar outflow from the quasar aligned with its companion star-forming galaxy (SFG) and several blobs of ionized gas in its vicinity identified in previous studies. Within the companion SFG we find evidence for a flattening of the synchrotron spectral index towards the point of intersection with the jet axis, further suggesting that the outflow may actually be impacting its interstellar medium (ISM). We discuss two possible mechanisms that could have triggered the starburst in the companion SFG: a wet-dry merger with the quasar and jet-induced star formation. While triggering through interaction-driven gas dynamics cannot be excluded with current data, our new observations make HE0450-2958 a strong candidate for jet-induced star formation, and one of the rare links between local systems (like Minkowski's Object or Centaurus A) and the high-z regime where radio-optical alignments suggest that this phenomenon could be more common.

description: Recently, graph neural networks (GNNs) have been successfully applied to predicting molecular properties, which is one of the most classical cheminformatics tasks with various applications. Despite their effectiveness, we empirically observe that training a single GNN model for diverse molecules with distinct structural patterns limits its prediction performance. In this paper, motivated by this observation, we propose TopExpert to leverage topology-specific prediction models (referred to as experts), each of which is responsible for each molecular group sharing similar topological semantics. That is, each expert learns topology-specific discriminative features while being trained with its corresponding topological group. To tackle the key challenge of grouping molecules by their topological patterns, we introduce a clustering-based gating module that assigns an input molecule into one of the clusters and further optimizes the gating module with two different types of self-supervision: topological semantics induced by GNNs and molecular scaffolds, respectively. Extensive experiments demonstrate that TopExpert has boosted the performance for molecular property prediction and also achieved better generalization for new molecules with unseen scaffolds than baselines. The code is available at https://github.com/kimsu55/ToxExpert.

Relaxation near supermassive black holes driven by nuclear spiral arms: anisotropic hypervelocity stars, S-stars and tidal disruption events

description: Nuclear spiral arms are small-scale transient spiral structures found in the centers of galaxies. Similarly to their galactic-scale counterparts, nuclear spiral arms can perturb the orbits of stars. In the case of the Galactic Center (GC), these perturbations can affect the orbits of stars and binaries in a region extending to several hundred parsecs around the supermassive black hole (MBH), causing diffusion in orbital energy and angular momentum. This diffusion process can drive stars and binaries to close approaches with the MBH, disrupting single stars in tidal disruption events (TDEs), or disrupting binaries, leaving a star tightly bound to the MBH, and an unbound star escaping the galaxy, i.e., a hypervelocity star (HVS). Here, we consider diffusion by nuclear spiral arms in galactic nuclei, specifying to the Milky Way GC. We determine nuclear spiral arm-driven diffusion rates using test-particle integrations, and compute disruption rates. Our TDE rates are up to 20% higher compared to relaxation by single stars. For binaries, the enhancement is up to a factor of ~100, and our rates are comparable to the observed numbers of HVSs and S-stars. Our scenario is complementary to relaxation driven by massive perturbers. In addition, our rates depend on the inclination of the binary with respect to the Galactic plane. Therefore, our scenario provides a novel potential source for the observed anisotropic distribution of HVSs. Nuclear spiral arms may also be important for accelerating the coalescence of binary MBHs, and for supplying nuclear star clusters with stars and gas.

description: We present a novel dataset collected by ASOS (a major online fashion retailer) to address the challenge of predicting customer returns in a fashion retail ecosystem. With the release of this substantial dataset we hope to motivate further collaboration between research communities and the fashion industry. We first explore the structure of this dataset with a focus on the application of Graph Representation Learning in order to exploit the natural data structure and provide statistical insights into particular features within the data. In addition to this, we show examples of a return prediction classification task with a selection of baseline models (i.e. with no intermediate representation learning step) and a graph representation based model. We show that in a downstream return prediction classification task, an F1-score of 0.792 can be found using a Graph Neural Network (GNN), improving upon other models discussed in this work. Alongside this increased F1-score, we also present a lower cross-entropy loss by recasting the data into a graph structure, indicating more robust predictions from a GNN based solution. These results provide evidence that GNNs could provide more impactful and usable classifications than other baseline models on the presented dataset and with this motivation, we hope to encourage further research into graph-based approaches using the ASOS GraphReturns dataset.

description: The two-step percolation behavior in aggregating systems was studied both experimentally and by means of Monte Carlo (MC) simulations. In experimental studies, the electrical conductivity, $σ$, of colloidal suspension of multiwalled carbon nanotubes (CNTs) in decane was measured. The suspension was submitted to mechanical de-liquoring in a planar filtration-compression conductometric cell. During de-liquoring, the distance between the measuring electrodes continuously decreased and the CNT volume fraction $φ$ continuously increased (from $10^{-3}$ up to $\approx 0.3$% v/v). The two percolation thresholds at $φ_{1}\lesssim 10^{-3}$ and $φ_{2}\approx 10^{-2}$ can reflect the interpenetration of loose CNT aggregates and percolation across the compact conducting aggregates, respectively. The MC computational model accounted for the core-shell structure of conducting particles or their aggregates, the tendency of a particle for aggregation, the formation of solvation shells, and the elongated geometry of the conductometric cell. The MC studies revealed two smoothed percolation transitions in $σ(φ)$ dependencies that correspond to the percolation through the shells and cores, respectively. The data demonstrated a noticeable impact of particle aggregation on anisotropy in electrical conductivity $σ(φ)$ measured along different directions in the conductometric cell.

description: Since 2003 the Planetary Virtual Observatory and Laboratory (PVOL) has been storing and serving publicly through its web site a large database of amateur observations of the Giant Planets (Hueso et al., 2010a). These images are used for scientific research of the atmospheric dynamics and cloud structure on these planets and constitute a powerful resource to address time changing phenomena in their atmospheres. Advances over the last decade in observation techniques, and a wider conscience by professional astronomers of the quality of amateur observations, have resulted in the necessity to upgrade this database. We here present major advances in the PVOL database that has evolved into a full virtual planetary observatory encompassing also observations of Mercury, Venus, Mars, the Moon and the Galilean satellites. Besides the new objects, the images can be tagged and the database allows simple and complex searches over the data. The new web service: PVOL2 is available online in http://pvol2.ehu.eus/ , contains a fully functional search engine and constitutes one of the many services included in VESPA (Virtual Europan Solar and Planetary Access). Data from PVOL2 can be served from the VESPA portal using the EPN-TAP protocol. PVOL2 also provides long-term storage to amateur observations containing about 30,000 amateur observations starting in the year 2000. Current and past observations from the amateur community provide a global view of the Solar System planets over the years with several possibilities for scientific analysis and amateur astronomers involvement in planetary science.

description: Baggrunden for dette paper er specialet Fordi min hund bedre kan li lædersæder fra december 2007 (Jacobsen 2007 et al.). Målet med specialet har været at undersøge, hvilke prioriteringer bilkøbere foretager sig i forbindelse med bilkøb og hvilke barrierer, det giver for et øget salg af miljøbiler og arbejdet har derfor været ud fra følgende problemformulering: Hvordan prioriterer bilkøbere de faktorer, som har betydning for deres valg af bil, hvad er købernes kendskab og holdning til miljø, og hvilke barrierer hindrer en større udbredelse af miljøbiler? Specialet tager i sin besvarelse af problemformuleringen udgangspunkt i en række interview med bilkøbere, som anskues ud fra Anthony Giddens teorier om mennesket i den moderne verden, Vincent Kaufmanns motilitetsbegreb, samt Malene Freudendal-Pedersens definitioner af strukturelle fortællinger. Undersøgelsen, som er foretaget som en del af specialeforløbet, består af 22 interview foretaget hos 4 forskellige bilforhandlere. I undersøgelsen medvirkede i alt 23 mænd og 9 kvinder. Interviewene er foretaget i umiddelbar forlængelse af købet og samtalen med bilsælgeren for at komme så tæt på de valg og prioriteringer, som har medført at bilkøberne har valgt netop deres nye bil.

European Self-Centeredness: The Drama of African and Other Migrants

description: On December 1, 2015 David Pryce-Jones, a British author, commentator, and senior editor of National Review offered his comments on what is today perceived as the immigration crisis in Europe, under the following headline: "Can the European Nation-State Survive the Current Wave of Mass Migration?" With the same centuries old self-centered perspective European governments seem unable to contemplate this monumental human crisis except from the threat that it may represent for the unmovable center of their citizenship rights in the so-called really civilized nations of the world, their values, economic stability, and moral and cultural standards. This paper departs from a different question: Can current waves of 'migrants' survive in Europe? to expose some of the Western-based ideologies that perceive everybody outside of dominant European ancestry as the "other" and their impact on the nature of global relations, peace, human ethics and responsibility.

description: A search for the production of heavy resonances decaying into top quark-antiquark pairs is presented. The analysis is performed in the lepton+jets and fully hadronic channels using data collected in proton-proton collisions at sqrt(s) = 13 TeV using the CMS detector at the LHC, corresponding to an integrated luminosity of 2.6 inverse femtobarns. The selection is optimized for massive resonances, where the top quarks have large Lorentz boosts. No evidence for resonant t t-bar production is found in the data, and upper limits on the production cross section of heavy resonances are set. The exclusion limits for resonances with masses above 2 TeV are significantly improved compared to those of previous analyses at sqrt(s) = 8 TeV.

description: Ultraviolet single-photon detector (UVSPD) provides a key tool for the applications requiring ultraweak light detection in the wavelength band. Here, we report a 4H-SiC single-photon avalanche diode (SPAD) based free-running UVSPD with ultralow afterpulse probability. We design and fabricate the 4H-SiC SPAD with a beveled mesa structure, which exhibits the characteristic of ultralow dark current. We further develop a readout circuit of passive quenching and active reset with tunable hold-off time setting to considerably suppress the afterpulsing effect. The nonuniformity of photon detection efficiency (PDE) across the SPAD active area with a diameter of $\sim$ 180 $μ$m is investigated for performance optimization. The compact UVSPD is then characterized, exhibiting a typical performance of 10.3% PDE, 133 kcps dark count rate and 0.3% afterpulse probability at 266 nm. Such performance indicates that the compact UVSPD could be used for practical ultraviolet photon-counting applications

Kuigi infusioonravi on tänapäeval üks enam kasutatud ravivõtteid, on teadusuuringud eri lahuste eeliste ja puuduste kohta üsna tagasihoidlikud. Kliinilises praktikas kasutatakse kõige rohkem kristalloidlahuseid. Neist enim kasutatud on naatriumkloriidi (NaCl) 0,9% lahus ja Ringeri laktaadilahus. Naatriumkloriidi 0,9% lahuse puhul on probleemiks hüperkloreemilise atsidoosi ja kaaliumi ainevahetuse häirete tekke risk. Hüperkloreemia omakorda on seotud halvemate ravitulemuste, ennekõike neerupuudulikkuse tekkega. Tasakaalustatud lahuste, näiteks Ringeri laktaadilahuse kasutamisel on hüperkloreemiat ja neerupuudulikkust vähem võrreldes NaCl 0,9% lahuse kasutamisega. Koertel tehtud eksperimendid on näidanud stabiilsemat vere pH-d Ringeri laktaadilahuse kasutamisel. NaCl 0,9% lahus on esmavalik neurokirurgias, kuna tasakaalustatud lahuste suhteline hüpotoonilisus võib neil patsientidel põhjustada koljusisese rõhu suurenemist. Lisaks on NaCl 0,9% lahus hea alkaloosi ja hüpokloreemia korrigeerimiseks. NaCl 0,9% lahuse kasutamisel on probleemiks ka lahjenduskoagulopaatia. Ringeri laktaadilahus on pigem seotud hüperkoagulatsiooniga, kuid selle kliiniline tähendus ei ole selge.

Spectroscopic evidence of Alfvén wave damping in the off-limb solar corona

Publisher: name: arXiv
Year: 2016
Subjects: subject: Solar and Stellar Astrophysics (astro-ph.SR)

description: We investigate off-limb active region and quiet Sun corona using spectroscopic data. Active region is clearly visible in several spectral lines formed in the temperature range of 1.1--2.8 MK. We derive electron number density using line ratio method, and non-thermal velocity in the off-limb region up to the distance of 140 Mm. We compare density scale heights derived from several spectral line pairs with expected scale heights as per hydrostatic equilibrium model. Using several isolated and unblended spectral line profiles, we estimate non-thermal velocities in active region and quiet Sun. Non-thermal velocities obtained from warm lines in active region first show increase and later show either decrease or almost constant value with height in the far off-limb region, whereas hot lines show consistent decrease. However, in the quiet Sun region, non-thermal velocities obtained from various spectral lines show either gradual decrease or remain almost constant with height. Using these obtained parameters, we further calculate Alfvén wave energy flux in the both active and quiet Sun regions. We find significant decrease in wave energy fluxes with height, and hence provide evidence of Alfvén wave damping. Furthermore, we derive damping lengths of Alfvén waves in the both regions and find them to be in the range of 25-170 Mm. Different damping lengths obtained at different temperatures may be explained as either possible temperature dependent damping or measurements obtained in different coronal structures formed at different temperatures along the line-of-sight. Temperature dependent damping may suggest some role of thermal conduction in the damping of Alfvén waves in the lower corona.

description: The digital event builds on the research experience of four speakers who have been engaged in different yet complementary ways with exploring issues of portraiture, cultural capital and memorialisation in artistic ecologies. Following a then/now heuristic approach, each panellist will discuss from an interdisciplinary and transdisciplinary perspective the portrait of a representative figure of Romanticism and map its multi-layered afterlives for different purposes across time. What is lost and what is gained in these transartistic, transcultural and transhistoric traffics? Is an author portrait a biographical, an autobiographical or an autobiografictive act? And what can transmediations and transculturation contribute to our knowledge of Romantic politics as well as their later appropriation and resignification? The topics to be discussed in this event include: the portrait and/in the public sphere; transhistorical constructions of authorship; portraiture and street art; transmedia authors; portraits in State documents and objects. The case studies the speakers will engage with to explore the multi-sided domain of Romantic portraiture and its afterlives are Jane Austen, Frances Burney, Walter Scott and Toussaint Louverture.

The speakers for this event are Dr Valentina Aparicio (Queen Mary, University of London), Dr Rita J. Dashwood (University of Liverpool), Professor Francesca Saggini (University of Edinburgh) .

description: We present late-time optical $R$-band imaging data from the Palomar Transient Factory (PTF) for the nearby type Ia supernova SN 2011fe. The stacked PTF light curve provides densely sampled coverage down to $R\simeq22$ mag over 200 to 620 days past explosion. Combining with literature data, we estimate the pseudo-bolometric light curve for this event from 200 to 1600 days after explosion, and constrain the likely near-infrared contribution. This light curve shows a smooth decline consistent with radioactive decay, except over ~450 to ~600 days where the light curve appears to decrease faster than expected based on the radioactive isotopes presumed to be present, before flattening at around 600 days. We model the 200-1600d pseudo-bolometric light curve with the luminosity generated by the radioactive decay chains of $^{56}$Ni, $^{57}$Ni and $^{55}$Co, and find it is not consistent with models that have full positron trapping and no infrared catastrophe (IRC); some additional energy escape other than optical/near-IR photons is required. However, the light curve is consistent with models that allow for positron escape (reaching 75% by day 500) and/or an IRC (with 85% of the flux emerging in non-optical wavelengths by day 600). The presence of the $^{57}$Ni decay chain is robustly detected, but the $^{55}$Co decay chain is not formally required, with an upper mass limit estimated at 0.014 M$_{\odot}$. The measurement of the $^{57}$Ni/$^{56}$Ni mass ratio is subject to significant systematic uncertainties, but all of our fits require a high ratio >0.031 (>1.3 in solar abundances).

description: My research proposal investigates a little known work by the American bibliophile and Johnson scholar, Alfred Edward Newton (1864-1940), entitled Dr Johnson: A Play (1923). The play has no modern reprints and had a modest circulation at the time of its publication.

My hypothesis is that Dr Johnson: A Play is a very interesting product, though sadly overlooked by critical discourse. It can be approached from the vantage point of adaptation and afterlives studies, particularly as regards the influence and biographical rewritings of Samuel Johnson. However, to me the play is also clearly relevant within the intricate context of post-First World War nostalgia, which has been of special concern to such authors as Charles Dickens and Jane Austen so far.

There is no systematic study of Dr Johnson: A Play and my inquiry would be of interest not only to the Johnson community and eighteenth-century scholars at large, but also to colleagues involved in the fields of adaptation studies and cultural transits.

description: Galactic outflows are believed to play an important role in regulating star formation in galaxies, but estimates of the outflowing mass and momentum have historically been based on uncertain assumptions. Here, we measure the mass, momentum, and energy outflow rates of seven nearby star-forming galaxies using ultraviolet absorption lines and observationally motivated estimates for the density, metallicity, and radius of the outflow. Low-mass galaxies generate outflows faster than their escape velocities with mass outflow rates up to twenty times larger than their star formation rates. These outflows from low-mass galaxies also have momenta larger than provided from supernovae alone, indicating that multiple momentum sources drive these outflows. Only 1-20\% of the supernovae energy is converted into kinetic energy, and this fraction decreases with increasing stellar mass such that low-mass galaxies drive more efficient outflows. We find scaling relations between the outflows and the stellar mass of their host galaxies (M$_\ast$) at the 2-3$σ$ significance level. The mass-loading factor, or the mass outflow rate divided by the star formation rate, scales as M$_\ast^{-0.4}$ and with the circular velocity as v$_\mathrm{circ}^{-1.6}$. The scaling of the mass-loading factor is similar to recent simulations, but the observations are a factor of five smaller, possibly indicating that there is a substantial amount of unprobed gas in a different ionization phase. The outflow momenta are consistent with a model where star formation drives the outflow while gravity counteracts this acceleration.

description: Abstract:
This is the second and final report of the Dayton ITS Demonstration Project, which evaluates the effectiveness of Advanced Traveler Information System (ATIS) devices located in the vicinity of the Nutter Center (Figure 1), Dayton, Ohio. The intention of these devices is to provide real-time information to travelers accessing the Nutter Center during special events. The first report documented the existing conditions (1999) and defined various measures of effectiveness used to evaluate the traffic conditions. The ATIS devices were installed in the meantime. To complete the evaluation of the demonstration project, this report evaluates the performance of the road network surrounding the Nutter Center after the implementation of the ATIS devices (hereafter referred to as present conditions). These conditions are compared to the conditions evaluated in the previous report (hereafter referred to as initial conditions). An analysis that quantifies the changes on the network performance is also presented here to determine the effects of the devices installed.
Outcome Logic: A Unifying Foundation for Correctness and Incorrectness Reasoning

description: Program logics for bug-finding (such as the recently introduced Incorrectness Logic) have framed correctness and incorrectness as dual concepts requiring different logical foundations. In this paper, we argue that a single unified theory can be used for both correctness and incorrectness reasoning. We present Outcome Logic (OL), a novel generalization of Hoare Logic that is both monadic (to capture computational effects) and monoidal (to reason about outcomes and reachability). OL expresses true positive bugs, while retaining correctness reasoning abilities as well. To formalize the applicability of OL to both correctness and incorrectness, we prove that any false OL specification can be disproven in OL itself. We also use our framework to reason about new types of incorrectness in nondeterministic and probabilistic programs. Given these advances, we advocate for OL as a new foundational theory of correctness and incorrectness.

description: A standard protocol for phenotyping structural and compositional aspects of the grape berry has been adopted by 18 East and West European germplasm collections during one season by testing a total of 469 accessions, including reference cultivars as well as local and minor germplasm accessions of specific interest. The protocol consists in the collection of triplicates for 26 phenotypic traits, from biological samples, each formed by 10 berries collected from 9 representative bunches from every analyzed accessions. The protocol concatenates the data from measurements and acquisitions, with the objective to generate new derived variables, which are expressed with different units (%; content per kg of grapes, per berry, per g of tissue). For each variable, the Least Significant Differences (LSD), to contrast a pair of single accession mean values, and the Confidence Intervals (CI), to estimate each single accession mean value, were computed. The application of the protocol revealed satisfactory results with high accuracy and efficiency in estimation of phenotypic traits of each accession. The whole data set will be useful for researchers, breeders and viticulturists in yield evaluation of grapevine cultivars, as well as in comparative analyses of environment-variety interaction.

Composite quantum Coriolis forces

description: The classical Coriolis force finds its quantum analogue in the difference $Σ(t)=H(t)-G(t)$ where the ``true'', observable Hamiltonian $H(t)$ represents the instantaneous energy. The other, ``false'' Hamiltonian $G(t)$ generates the time-evolution of wave functions. Whenever $Σ(t)\neq 0$, quantum mechanics acquires an interaction-picture form. Then, the time-evolution of every observable is generated by the Coriolis operator $Σ(t)$ ({\it alias} ``Heisenberg'' Hamiltonian) itself. In the paper a sequence of alternative formulae for $Σ(t)$ is derived under the assumption of an $N-$term factorization of the Dyson-map operator $Ω(t)$ (defined as converting a preselected quasi-Hermitian $H(t)$ into its conventional self-adjoint avatar). It is shown that in the resulting innovative formalism called ``factorization-based non-Hermitian interaction picture'' (FNIP) one has a choice between $N+1$ alternative forms of the description of quantum dynamics, one of which may prove, for the underlying quantum system, optimal. For illustration, the ``wrong-sign'' anharmonic oscillator model is recalled.

description: We report the first detailed chemical abundance analysis of the exoplanet-hosting M-dwarf stars Kepler-138 and Kepler-186 from the analysis of high-resolution ($R$ $\sim$ 22,500) $H$-band spectra from the SDSS IV - APOGEE survey. Chemical abundances of thirteen elements - C, O, Na, Mg, Al, Si, K, Ca, Ti, V, Cr, Mn, and Fe - are extracted from the APOGEE spectra of these early M-dwarfs via spectrum syntheses computed with an improved line list that takes into account H$_{2}$O and FeH lines. This paper demonstrates that APOGEE spectra can be analyzed to determine detailed chemical compositions of M-dwarfs. Both exoplanet-hosting M-dwarfs display modest sub-solar metallicities: [Fe/H]$_{Kepler-138}$ = -0.09 $\pm$ 0.09 dex and [Fe/H]$_{Kepler-186}$ = -0.08 $\pm$ 0.10 dex. The measured metallicities resulting from this high-resolution analysis are found to be higher by $\sim$0.1-0.2 dex than previous estimates from lower-resolution spectra. The C/O ratios obtained for the two planet-hosting stars are near-solar, with values of 0.55 $\pm$ 0.10 for Kepler-138 and 0.52 $\pm$ 0.12 for Kepler-186. Kepler-186 exhibits a marginally enhanced [Si/Fe] ratio.

An Effective Two-Flavor Approximation for Neutrino Survival Probabilities in Matter
Creators: name: Minakata, Hisakazu
Publisher: name: arXiv

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

description: It is known in vacuum that the three-flavor neutrino survival probability can be approximated by the effective two-flavor form to first orders in $ε\equiv Δm^2_{21} / Δm^2_{31}$, with introduction of the effective $Δm^2_{αα}$ ($α= e, μ, τ$), in regions of neutrino energy $E$ and baseline $L$ such that $Δm^2_{31} L / 2E \sim π$. Here, we investigate the question of whether the similar effective two-flavor approximation can be formulated for the survival probability in matter. Using a perturbative framework with the expansion parameters $ε$ and $s_{13} \propto \sqrtε$, we give an affirmative answer to this question and the resultant two-flavor form of the probability is valid to order $ε$. However, we observe a contrived feature of the effective $Δm^2_{αα} (a)$ in matter. It ceases to be a combination of the fundamental parameters and has energy dependence, which may be legitimate because it comes from the matter potential. But, it turned out that $Δm^2_{μμ} (a)$ becomes $L$-dependent, though $Δm^2_{ee} (a)$ is not, which casts doubt on adequacy of the concept of effective $Δm^2$ in matter. We also find that the appearance probability in vacuum admits, to order $ε$, the similar effective two-flavor form with a slightly different effective $Δm^2_{βα}$ from the disappearance channel. A general result is derived to describe suppression of the matter effect in the oscillation probability.

description: The ThEdu series pursues the smooth transition from an intuitive way of doing mathematics at secondary school to a more formal approach to the subject in STEM education, while favouring software support for this transition by exploiting the power of theorem-proving technologies. What follows is a brief description of how the present volume contributes to this enterprise. The 11th International Workshop on Theorem Proving Components for Educational Software (ThEdu'22), was a satellite event of the 8th Federated Logic Conference (FLoC 2022), July 31-August 12, 2022, Haifa, Israel ThEdu'22 was a vibrant workshop, with two invited talk by Thierry Dana-Picard (Jerusalem College of Technology, Jerusalem, Israel) and Yoni Zohar (Bar Ilan University, Tel Aviv, Israel) and four contributions. An open call for papers was then issued, and attracted seven submissions. Those submissions have been accepted by our reviewers, who jointly produced at least three careful reports on each of the contributions. The resulting revised papers are collected in the present volume. The contributions in this volume are a faithful representation of the wide spectrum of ThEdu, ranging from those more focused on the automated deduction research, not losing track of the possible applications in an educational setting, to those focused on the applications, in educational settings, of automated deduction tools and methods. We, the volume editors, hope that this collection of papers will further promote the development of theorem-proving based software, and that it will allow to improve the mutual understanding between computer scientists, mathematicians and stakeholders in education. While this volume goes to press, the next edition of the ThEdu workshop is being prepared: ThEdu'23 will be a satellite event of the 29th international Conference on Automated Deduction (CADE 2023), July 1-4, 2023, Rome, Italy.
