description: The STEREO experiment, aiming to probe short baseline neutrino oscillations by precisely measuring reactor anti-neutrino spectrum, is currently under installation. It is located at short distance from the compact research reactor core of the Institut Laue-Langevin, Grenoble, France. Dedicated electronics, hosted in a single $μ$TCA crate, were designed for this experiment. In this article, the electronics requirements, architecture and the performances achieved are described. It is shown how intrinsic Pulse Shape Discrimination properties of the liquid scintillator are preserved and how custom adaptable logic is used to improve the muon veto efficiency.

description: The transition temperatures of epitaxial films of Fe(Te0:9Se0:1) are remarkably insensitive to applied magnetic field, leading to predictions of upper critical fields Bc2(T = 0) in excess of 100 T. Using pulsed magnetic fields, we find Bc2(0) to be on the order of 45 T, similar to values in bulk material and still in excess of the paramagnetic limit. The same films show strong magnetoresistance in fields above Bc2(T), consistent with the observed Kondo minimum seen above Tc. Fits to the temperature dependence in the context of the WHH model, using the experimental value of the Maki parameter, require an effective spin-orbit relaxation parameter of order unity. We suggest that Kondo localization plays a similar role to spin-orbit pair breaking in making WHH fits to the data.

description: This project analyzes the connections between race, place, and identity as articulated by Shakespeare’s modern-day Black adaptors. My research on race and placelessness makes a literal consideration of what Dr. Koritha Mitchell has termed “know-your-place aggression,” which considers how anti-Black racists deploy violence to keep Black people from achieving civic and social success. Centering land and locality, my research highlights how the prevailing focus on acts of racist aggression themselves has overshadowed the significance of landscape, geography, and geopolitics in race formation and how racist violence often intersects with a desire to prevent Black people’s access to certain places. My approach brings nation, region, migration, and other forms of “placehood” to the analysis of Black culture and anti-Black racism throughout the African diaspora, especially in USian, Canadian, and Caribbean contexts. In this multidisciplinary project, I assemble scholarship on medieval and early modern history, early modern literary and performance cultures, records of 19th-century European and American Shakespeare performances, and 20th an 21st-century critical interventions on the topics of race and identity in Shakespeare studies. From this array of primary and secondary sources, I argue that Black artists’ engagement with Shakespeare’s plays necessarily interrogate the notions of origin and originality as they pertain to diasporic identity and adaptation, respectively. I further argue that the literary and artistic output of Black diasporic people can be examined as a constellation of adaptive strategies that respond to Shakespeare and other Western canonical writers and thinkers. Doing so, these creators recuperate progressive potential in diasporic placelessness from the histories of colonialism, expropriation, and chattel slavery that obscure racial and cultural origins.

description: This paper presents a formulation for brittle fracture in 3D elastic solids within the context of configurational mechanics. The local form of the first law of thermodynamics provides a condition for equilibrium of the crack front. The direction of the crack propagation is shown to be given by the direction of the configurational forces on the crack front that maximise the local dissipation. The evolving crack front is continuously resolved by the finite element mesh, without the need for face splitting or the use of enrichment techniques. A monolithic solution strategy is adopted, solving simultaneously for both the material displacements (i.e. crack extension) and the spatial displacements, is adopted. In order to trace the dissipative loading path, an arc-length procedure is developed that controls the incremental crack area growth. In order to maintain mesh quality, smoothing of the mesh is undertaken as a continuous process, together with face flipping, node merging and edge splitting where necessary. Hierarchical basis functions of arbitrary polynomial order are adopted to increase the order of approximation without the need to change the finite element mesh. Performance of the formulation is demonstrated by means of three representative numerical simulations, demonstrating both accuracy and robustness.

title: Combinatorial culture: a hominin adaptation detected through use-wear analysis
Creators: name: Scott, Christopher
Publisher: name: University of Liverpool Repository
Year: 2027

description: Human cultural adaptation is uniquely structured by combination and recombination, with the behaviours of cooperation, language, and composite material culture presented as key elements. The emergence of this combinatorial culture is poorly understood, with theoretical evidence suggesting an early Middle Pleistocene genesis within a variability selection framework. Searching for combinatorial culture is best approached by archaeological detection of its physical manifestation, in the form of lithics, which in antiquity were hafted to a handle. Building on the work of Rots (2010), this is shown to be best approached with experimentally informed lithic use-wear analysis. An extensive experimental program is undertaken, with the results from this reference data explored using heatmaps, density-based cluster analysis, and predictive modelling using multinomial logistic regression. These analytical approaches, along with blind testing, demonstrate that use-wear is a suitable method for the detection of experimental bifaces which have been hafted. Five bifaces from the Middle Pleistocene site of Beeches Pit, UK, are analysed using both a traditional use-wear approach, and with the use of the predictive models. While the results do not indicate hafting, they do show that two of the tools were used for butchery related tasks, and that one of the bifaces was used as a strike-a-light. The detection of a strike-a-light at Beeches Pit, extends the chronology of this technology by approximately 400,000 years. Strike-a-light technology also represents a form of combinatorial culture in its technological and social complexity.

description: The problem of monoenergetic neutral particle transport in a duct, where particles travel inside the duct walls, is treated using an approximate one-dimensional model. The one-dimensional model uses three-basis functions, as part of a previously derived weighted-residual procedure, to account for the geometry of particle transport in a duct system (where particle migration into the walls is not considered). Our model introduces two stochastic parameters to account for particle-wall interactions: an albedo approximation yielding the fraction of particles that return to the duct after striking the walls, and a mean-distance travelled in the walls transverse to the duct by particles that re-enter the duct. Our model produces a set of three transport equations with a non-local scattering kernel. We solve these equations using discrete ordinates with source iteration. Numerical results for the reflection and transmission probabilities of neutron transport in ducts of circular cross section are compared to Monte Carlo results computed using the MCNP code.

description: Four-dimensional compactifications of string theory provide a controlled set of possible gauge representations accounting for BSM particles and dark sector components. In this review, constraints from perturbative Type II string compactifications in the geometric regime are discussed in detail and then compared to results from heterotic string compactifications and non-perturbative/non-geometric corners. As a prominent example, an open string realization of the QCD axion is presented. The status of deriving the associated low-energy effective action in four dimensions is discussed and open avenues of major phenomenological importance are highlighted. As examples, a mechanism of closed string moduli stabilization by D-brane backreaction as well as one-loop threshold corrections to the gauge couplings and balancing a low string scale $M_{\text{string}}$ with unisotropic compact dimensions are discussed together with implications on potential future new physics observations. For illustrative purposes, an explicit example of a globally consistent D6-brane model with MSSM-like spectrum on $T^6/(\mathbb{Z}_2 \times \mathbb{Z}_6 \times Ω{\cal R})$ is presented.

description: Scalar particles $S$ which are singlets under the Standard Model gauge group are generic features of many models of fundamental physics, in particular as possible mediators to a hidden sector. We show that the decay $S\to Zh$ provides a powerful probe of the CP nature of the scalar, because it is allowed only if $S$ has CP-odd interactions. We perform a model-independent analysis of this decay using an effective Lagrangian and compute the relevant Wilson coefficients arising from integrating out heavy fermions to one-loop order.

title: Rethinking Causation in English Criminal Law: The Role of INUS Causation
Creators: name: Firkins, Grant
Publisher: name: University of Liverpool Repository
Year: 2029

description: This thesis argues that the current standard tests for causation in English criminal law should be replaced with a single test, known as ‘INUS’ causation – where a cause is an insufficient but necessary part of an unnecessary but sufficient condition. It argues that the standard tests represent a normative exercise in finding the defendant (D) responsible for a prohibited outcome, often grounded only in D’s moral responsibility for that outcome. Such an approach is problematic because moral responsibility is irrelevant to causal responsibility; and a failure to distinguish causal responsibility from moral responsibility results in inappropriate criminal- responsibility ascription for result crimes. In contrast, INUS would provide a single, non- normative test of causation; a metaphysical one that offers a robust causal enquiry which focuses only on causal responsibility, thereby contributing more appropriately to criminal- responsibility ascription. INUS would also yield practical benefits since it can engage with causal enquires in a broader range of cases on a more principled, clear and consistent basis.

Having argued the case for the INUS approach, this thesis examines some of the potentially problematic implications of adopting INUS in English criminal law via two case studies: one on strict-liability offences involving injury or death by driving and one on complicity liability. For the first case study, the focus is on such offences as they are the main stigmatic strict-liability result crimes which raise causal problems. The thesis contends that adoption of INUS would alter the liability outcomes in cases involving these offences so that instead of being acquitted, the defendants would be criminally liable. This is because INUS removes the blameworthy requirement which has been injected into the standard tests of causation. However, this would yield fair-labelling concerns for these crimes which could be addressed by importing a blameworthy element into the offences, specifically by importing the requirement of ‘careless driving’.

INUS would also affect our understanding of complicity liability. According to INUS, there is typically no causal connection between the accomplice’s assistance or encouragement and the principal’s offence. Adoption of INUS would therefore confirm that the rationale of complicity liability does not lie in any causal connection between the accomplice’s assistance or encouragement and the principal’s offence. However, this would yield criminal- responsibility and fair-labelling concerns which could be addressed by reforms to complicity that reconcile it with these principles of criminal justice. The thesis therefore proposes a new independent offence of ‘assisting or encouraging an offence’.
The compact H$α$ emitting regions of the Herbig Ae/Be stars HD 179218 and HD 141569 from CHARA spectro-interferometry

description: This work presents CHARA/VEGA H$α$ spectro-interferometry (R ~ 6000, and $λ$/2B ~ 1 mas) of HD 179218 and HD 141569, doubling the sample of Herbig Ae/Be (HAeBe) stars for which this type of observations is available so far. The observed H$α$ emission is spatially unresolved, indicating that the size of the H$α$ emitting region is smaller than ~ 0.21 and 0.12 au for HD 179218 and HD 141529 (~ 15 and 16 R*, respectively). This is smaller than for the two other HAeBes previously observed with the same instrumentation. Two different scenarios have been explored in order to explain the compact line emitting regions. A hot, several thousand K, blackbody disc is consistent with the observations of HD 179218 and HD 141569. Magnetospheric accretion (MA) is able to reproduce the bulk of the H$α$ emission shown by HD 179218, confirming previous estimates from MA shock modelling with a mass accretion rate of 10^-8 Msun/yr, and an inclination to the line of sight between 30 and 50 degr. The H$α$ profile of HD 141569 cannot be fitted from MA due to the high rotational velocity of this object. Putting the CHARA sample together, a variety of scenarios is required to explain the H$α$ emission in HAeBe stars -compact or extended, discs, accretion, and winds-, in agreement with previous Br$γ$ spectro-interferometric observations.

Percolation study for the capillary ascent of a liquid through a granular soil

description: Capillary rise plays a crucial role in the construction of road embankments in flood zones, where hydrophobic compounds are added to the soil to suppress the rising of water and avoid possible damage of the pavement. Water rises through liquid bridges, menisci and trimers, whose width and connectivity depends on the maximal half-length λ of the capillary bridges among grains. Low λ generate a disconnect structure, with small clusters everywhere. On the contrary, for high λ, create a percolating cluster of trimers and enclosed volumes that form a natural path for capillary rise. Hereby, we study the percolation transition of this geometric structure as a function of λ on a granular media of monodisperse spheres in a random close packing. We determine both the percolating threshold λ_{c} = (0.049 \pm 0.004)R (with R the radius of the granular spheres), and the critical exponent of the correlation length ν = (0.830 \pm 0.051), suggesting that the percolation transition falls into the universality class of ordinary percolation.
The information content of stellar halos: Stellar population gradients and accretion histories in early-type Illustris galaxies

description: Long dynamical timescales in the outskirts of galaxies preserve the information content of their accretion histories, for example in the form of stellar population gradients. We present a detailed analysis of the stellar halo properties of a statistically representative sample of early-type galaxies from the Illustris simulation and show that stellar population gradients at large radii can indeed be used to infer basic properties of galactic accretion histories. We measure metallicity, age, and surface-brightness profiles in quiescent Illustris galaxies ranging from $\mathrm{M}_\star = 10^{10} - 2\times 10^{12}\;\mathrm{M}_\odot$ and show that they are in reasonable agreement with observations. At fixed mass, galaxies that accreted little of their stellar halo material tend to have steeper metallicity and surface-brightness profiles between 2 - 4 effective radii (R$_e$) than those with larger accreted fractions. Profiles of metallicity and surface-brightness in the stellar halo typically flatten from z = 1 to the present. This suggests that the accretion of stars into the stellar halo tends to flatten metallicity and surface-brightness profiles, a picture which is supported by the tight correlation between the two gradients in the stellar halo. We find no statistical evidence of additional information content related to accretion histories in stellar halo metallicity profiles beyond what is contained in surface-brightness profiles. Age gradients in the stellar halo do not appear to be sensitive to galactic accretion histories, and none of the stellar population gradients studied are strongly correlated with the mean merger mass-ratio. Future observations that reach large radii outside galaxies will have the best potential to constrain galactic accretion histories.

description: Supermassive black hole binaries (SMBHs) are expected to result from galaxy mergers, and thus are natural byproducts (and probes) of hierarchical structure formation in the Universe. They are also the primary expected source of low-frequency gravitational wave emission. We search for binary BHs using time-variable velocity shifts in broad Mg II emission lines of quasars with multi-epoch observations. First, we inspect velocity shifts of the binary SMBH candidates identified in Ju et al. (2013), using SDSS spectra with an additional epoch of data that lengthens the typical baseline to ~10 yr. We find variations in the line-of-sight velocity shifts over 10 years that are comparable to the shifts observed over 1-2 years, ruling out the binary model for the bulk of our candidates. We then analyze 1438 objects with 8 yr median time baselines, from which we would expect to see velocity shifts >1000 km/s from sub-pc binaries. We find only one object with an outlying velocity of 448 km/s, indicating, based on our modeling, that ~< 1 per cent (the value varies with different assumptions) of SMBHs that are active as quasars reside in binaries with ~0.1 pc separations. Binaries either sweep through these small separations rapidly or stall at larger radii.

description: Since the emergence of the new class of extremely bright transients, super-luminous supernovae (SLSNe), three main mechanisms to power their light curves (LCs) have been discussed. They are the spin-down of a magnetar, interaction with circumstellar material, and the decay of large amounts of radioactive nickel in pair-instability supernovae (PISNe). Given the high degree of diversity seen within the class, it is possible that all three mechanisms are at work. PISN models can be self- consistently simulated from the main sequence phase of very massive stars (VMS) through to their explosion. These models robustly predict large amounts of radioactive nickel and thus very luminous SN events. However, PISN model LCs evolve more slowly than even the slowest evolving SLSNe. Multidimensional effects on the ejecta structure, specifically the mixing of radioactive nickel out to large radii, could alleviate this discrepancy with observation. Here we explore the multidimensional effects on the LC evolution by simulating the explosion phase in 1D, 2D, and 3D. We find that the ejecta from the multidimensional simulations have slightly shallower abundance gradients due to mixing at shell boundaries. We compute synthetic LCs whose shapes show no discernible differences due to the multidimensional effects.

title: Encountering the Other: Phenomenology in Architectural Discourse and Its Underplayed Theme of Intersubjectivity
Creators: name: Liu, Qing
Publisher: name: The Open University
Year: 2024

description: Looking into what can be termed a tradition of architectural phenomenology and the criticism it encountered over the last several decades, this dissertation contends that given the recent attempts to transform and reinvent architectural phenomenology, it is of urgent necessity to thematize intersubjectivity in the development of a phenomenological understanding, when theorizing the meaning of architecture. Contrary to the popular interpretation that architectural phenomenology deliberately endorses a specific way of life, a specific account of the body, a specific conception of subjectivity, therefore unable to take alterity and novelty into consideration, the dissertation tries to demonstrate that architectural phenomenology has underplayed the theme of (inter)subjectivity and underestimated its importance, that a phenomenological investigation of (inter)subjectivity contains many philosophical insights into alterity and novelty constructive to architectural theory and practice.
The dissertation provides a genealogy of architectural phenomenology, assesses the coherence of its discursive practice, and clarifies the notion of intersubjectivity to be further investigated with the newly available support of contemporary phenomenology. It traces the underplayed theme of intersubjectivity in the tradition, choosing two prominent figures as the anchors for contextualization—Dalibor Vesely and Ernesto Nathan Rogers. Through a critical examination of their theoretical contributions along with the relevant philosophical problems, it reveals the overlooked potential of architectural phenomenology to talk about other subjectivities and new works concretely situated in the environment and in history, thus proposing an alternative approach that can address socio-political issues. It concludes by pointing out how this approach, formed on a phenomenological sensitivity to alterity and novelty, indicative of a significant turn in theorizing the communication and creation of meaning, sheds light on the ongoing polemics revolving around architectural phenomenology.

description: We show that measurements of the fluctuations in the near-infrared background (NIRB) from the AKARI satellite can be explained by faint galaxy populations at low redshifts. We demonstrate this using reconstructed images from deep galaxy catalogs (HUGS/S-CANDELS) and two independent galaxy population models. In all cases, we find that the NIRB fluctuations measured by AKARI are consistent with faint galaxies and there is no need for a contribution from unknown populations. We find no evidence for a steep Rayleigh-Jeans spectrum for the underlying sources as previously reported. The apparent Rayleigh-Jeans spectrum at large angular scales is likely a consequence of galaxies being removed systematically to deeper levels in the longer wavelength channels.

description: We present radio observations of 18 MIPSGAL bubbles performed at 5 GHz (6 cm) with the Karl G. Jansky Very Large Array in configuration B and BnA. The observations were aimed at understanding what kind of information high-resolution and high-sensitivity radio maps can supply on the circumstellar envelopes of different kinds of evolved stars and what their comparison with infrared images with similar resolution can tell us. We found that the 18 bubbles can be grouped into five categories according to their radio morphology. The three bubbles presenting a central point source in the radio images all correspond to luminous blue variable star candidates. Eleven bubbles show an elliptical shape and the total lack of a central object in the radio, and are likely associated with planetary nebulae. Under this assumption we derive their distance, their ionized mass and their distribution on the Galactic plane. We discuss the possibility that the MIPSGAL bubbles catalogue (428 objects) may contain a large fraction of all Galactic planetary nebulae located at a distance between 1.4 kpc and 6.9 kpc and lying in the MIPSGAL field of view. Among the remaining bubbles we identify also a H II region and a proto-planetary nebula candidate.

A certain interaction is applied to a mass to provide a particular spectrum of stationary energies. The related spectrum of the harmonic oscillator potential acting on the TDM oscillators is found. We apply the time version of the asymptotic iteration method (AIM) to calculate analytical expressions of the TDM stationary state energies and their wave functions. It is shown that the obtained solutions reduce to those of simple harmonic oscillator as the time-dependent of the mass reduces to

These observations suggest the two velocity components of M0.20-0.033 are physically connected in the south. Additional ATCA observations suggest this connection is due to an expanding shell in the molecular gas, with the centroid located near the Quintuplet cluster. The G0.10-0.08 molecular cloud has little radio continuum, strong molecular emission, and abundant CH3OH masers, similar to a nearby molecular cloud with no star formation: M0.25+0.01. These features detected in G0.10-0.08 suggest dense molecular gas with no signs of current star formation.

description: We introduce two new graphical-level relations among possible contributions to the four-point correlation function and scattering amplitude in planar, maximally supersymmetric Yang-Mills theory. When combined with the rung rule, these prove powerful enough to fully determine both functions through ten loops. This then also yields the full five-point amplitude to eight loops and the parity-even part to nine loops.

description: [PT] Arquitetura Paisagista: do lugar do documento de arquivo à construção de uma história

Existe uma lacuna na história da arquitetura paisagista em Portugal que é necessário recuperar, não só pelo legado histórico e cultural da história disciplinar, mas também para pensar epistemologicamente a própria disciplina com respeito às preocupações ambientais na agenda política. A questão que se coloca é de como lhe conferir visibilidade, hoje, problematizando essa hipótese a partir do acesso aos documentos de arquivo. Cartografando os documentos de arquitetura paisagista no contexto Português e o estado em que os mesmos se encontram em termos de salvaguarda e de acesso, problematiza-se a importância destes arquivos e do tratamento arquivístico destes documentos para a construção de uma narrativa histórica, ou de como o seu não tratamento poderá contribuir para apagamento disciplina que faz agora oito décadas.

[EN] Landscape architecture: from the archive to the construction of a narrative

There is a gap in the history of landscape architecture in Portugal. It needs to be recovered for historical and cultural reasons and to the disciplines' epistemology concerning environmental issues on the political agenda. The point is how to give it visibility today, questioning this hypothesis by providing access to archival documents. Mapping landscape architecture documents in the Portuguese context and its safeguard and access conditions; this paper problematises the importance of these archives and records for constructing a historical narrative. Or how its non-treatment may contribute to the erasure of a discipline with eight decades.

Tidal disruption rates in non-spherical galactic nuclei formed by galaxy mergers

description: We explore the rates of tidal disruption events (TDEs) of stars by supermassive black holes (SBHs) in galactic nuclei formed in mergers followed by a formation and coalescence of a binary SBH. Such systems initially have a deficit of stars on low-angular-momentum orbits caused by the slingshot process during the binary SBH stage, which tends to reduce the flux of stars into the SBH compared to the steady-state value. On the other hand, a newly formed galactic nucleus has a non-spherical shape which enhances the mixing of stars in angular momentum and thus the TDE rate. In galaxies with relatively low SBH masses (<10^7 Msun), relaxation times are short enough to wash out the anisotropy in initial conditions, and for more massive SBH the enhancement of flux due to non-sphericity turns out to be more important than its suppression due to initial anisotropy. Therefore, the present-day TDE rates generally exceed conventional steady-state estimates based on a spherical isotropic approximation. We thus conjecture that the lower observationally inferred TDE rates compared to theoretical predictions cannot be attributed to the depletion of low-angular-momentum stars by SBH binaries.

description: This paper presents a number of experiments to model changes in a historical Portuguese corpus composed of literary texts for the purpose of temporal text classification. Algorithms were trained to classify texts with respect to their publication date taking into account lexical variation represented as word n-grams, and morphosyntactic variation represented by part-of-speech (POS) distribution. We report results of 99.8% accuracy using word unigram features with a Support Vector Machines classifier to predict the publication date of documents in time intervals of both one century and half a century. A feature analysis is performed to investigate the most informative features for this task and how they are linked to language change.

Kinetic analysis of spin current contribution to spectrum of electromagnetic waves in spin-1/2 plasma, Part II: Dispersion dependencies

description: The dielectric permeability tensor for spin polarized plasmas derived in terms of the spin-1/2 quantum kinetic model in six-dimensional phase space in Part I of this work is applied for study of spectra of high-frequency transverse and transverse-longitudinal waves propagating perpendicular to the external magnetic field. Cyclotron waves are studied at consideration of waves with electric field directed parallel to the external magnetic field. It is found that the separate spin evolution modifies the spectrum of cyclotron waves. These modifications increase with the increase of the spin polarization and the number of the cyclotron resonance. Spin dynamics with no account of the anomalous magnetic moment gives a considerable modification of spectra either. The account of anomalous magnetic moment leads to a fine structure of each cyclotron resonance. So, each cyclotron resonance splits on three waves. Details of this spectrum and its changes with the change of spin polarization are studied for the first and second cyclotron waves. A cyclotron resonance existing at $ω\approx0.001\midΩ_{e}\mid$ due to the anomalous magnetic moment is also described, where $\midΩ_{e}\mid$ is the cyclotron frequency. The ordinary waves does not have any considerable modification. The electrostatic and electromagnetic Berstein modes are studied during the analysis of waves propagating perpendicular to the external magnetic field with the electric field perturbation directed perpendicular to the external field. A modification of the oscillatory structure caused by the equilibrium spin polarization is found in both regimes. Similar modification is found for the extraordinary wave spectrum.

description: An important aspect of searching for exoplanets is understanding the binarity of the host stars. It is particularly important because nearly half of the solar-like stars within our own Milky Way are part of binary or multiple systems. Moreover, the presence of two or more stars within a system can place further constraints on planetary formation, evolution, and orbital dynamics. As part of our survey of almost a hundred host stars, we obtained images at 692 nm and 880 nm bands using the Differential Speckle Survey Instrument (DSSI) at the Gemini-North Observatory. From our survey, we detect stellar companions to HD 2638 and HD 164509. The stellar companion to HD 2638 has been previously detected, but the companion to HD 164509 is a newly discovered companion. The angular separation for HD 2638 is $0.512 \pm 0.002\arcsec$ and for HD 164509 is $0.697 \pm 0.002\arcsec$. This corresponds to a projected separation of $25.6 \pm 1.9$ AU and $36.5 \pm 1.9$ AU, respectively. By employing stellar isochrone models, we estimate the mass of the stellar companions of HD 2638 and HD 164509 to be $0.483 \pm 0.007$ $M_\sun$ and $0.416 \pm 0.007$ $M_\sun$, respectively, and their effective temperatures to be $3570 \pm 8$~K and $3450 \pm 7$~K, respectively. These results are consistent with the detected companions being late-type M dwarfs.

description: We present an analysis of the performance of machine learning classifiers on discriminating between similar languages and language varieties. We carried out a number of experiments using the results of the two editions of the Discriminating between Similar Languages (DSL) shared task. We investigate the progress made between the two tasks, estimate an upper bound on possible performance using ensemble and oracle combination, and provide learning curves to help us understand which languages are more challenging. A number of difficult sentences are identified and investigated further with human annotation.

description: We study the effect of disorder on the semimetal -- Mott insulator transition in the half-filled repulsive Hubbard model on a honeycomb lattice, a system that features vanishing density of states at the Fermi level. Using the determinant quantum Monte Carlo method, we characterize various phases in terms of the bulk-limit antiferromagnetic (AF) order parameter, compressibility, and temperature-dependent DC conductivity. In the clean limit, our data are consistent with previous results showing a single quantum critical point separating the semi-metallic and AF Mott insulating phases. With the presence of randomness, a non-magnetic disordered insulating phase emerges. Inside this disordered insulator phase, there is a crossover from a gapless Anderson-like insulator to a gapped Mott-like insulator.

description: A domain wall and spin supercurrent can coexist in magnets with easy-cone anisotropy owing to simultaneous spontaneous breaking of Z$_2$ and U(1) symmetries. Their interaction is theoretically investigated in quasi one-dimensional ferromagnets within the Landau-Lifshitz-Gilbert phenomenology. Specifically, we show that spin supercurrent can exert the torque on a domain wall and thereby drive it. We also show, as a reciprocal phenomenon, a field-induced motion of a domain wall can generate spin supercurrent.
