description: Quadratic irrationals posses a periodic continued fraction expansion. Much less is known about cubic irrationals. We do not even know if the partial quotients are bounded, even though extensive computations suggest they might follow Kuzmin's probability law. Results are given for sequences of partial quotients of positive irrational numbers $ξ$ and $m \over ξ$ with $m$ a natural number. A big partial quotient in one sequence finds a connection in the other.

Highly comparative feature-based time-series classification

description: A highly comparative, feature-based approach to time series classification is introduced that uses an extensive database of algorithms to extract thousands of interpretable features from time series. These features are derived from across the scientific time-series analysis literature, and include summaries of time series in terms of their correlation structure, distribution, entropy, stationarity, scaling properties, and fits to a range of time-series models. After computing thousands of features for each time series in a training set, those that are most informative of the class structure are selected using greedy forward feature selection with a linear classifier. The resulting feature-based classifiers automatically learn the differences between classes using a reduced number of time-series properties, and circumvent the need to calculate distances between time series. Representing time series in this way results in orders of magnitude of dimensionality reduction, allowing the method to perform well on very large datasets containing long time series or time series of different lengths. For many of the datasets studied, classification performance exceeded that of conventional instance-based classifiers, including one nearest neighbor classifiers using Euclidean distances and dynamic time warping and, most importantly, the features selected provide an understanding of the properties of the dataset, insight that can guide further scientific investigation.

description: We examine Lorentz-violating effects that could appear through deviations of the Standard Model gauge couplings WWgamma and WWgammagamma. These new physics effects are explored on the gamma gamma -> WW reaction at the International Linear Collider. In particular, the associated helicity amplitudes are computed in the context of the Standard Model Extension (which is a model-independent approach to CPT and Lorentz violation) and the Effective Lagrangian Model (which incorporates new physics effects that respect CPT and Lorentz violation). We perform an exhaustive study of the polarized differential cross sections to stand out effects related to Lorentz symmetry violation, where it is evidenced that the effects of Lorentz symmetry violation are more sensitive to the presence of the b constant background field. We found that for the $(\pm,\pm,(L,T+T,L))$ polarization state, only Standard Model Extension and Effective Lagrangian Model contribute at the lowest order, however, both types of new physics effects are clearly distinguished, being dominant the convoluted cross section of the Standard Model Extension in around 4 orders of magnitude. For this polarization state, at the last stage of operation of International Linear Collider, it is expected an integrated luminosity of 10^3 fb^{-1}, finding around of 2 events for a Lorentz-violating energy scale of 32 TeV.

description: The Lindemann criterion is reformulated in terms of the average shear modulus $G_c$ of the melting crystal, indicating a critical melting shear strain which is necessary to form the many different inherent states of the liquid. In glass formers with covalent bonds, one has to distinguish between soft and hard degrees of freedom to reach agreement. The temperature dependence of the picosecond mean square displacements of liquid and crystal shows that there are two separate contributions to the divergence of the viscosity with decreasing temperature: the anharmonic increase of the shear modulus and a diverging correlation length .

description: Video moment retrieval (VMR) aims to localize target moments in untrimmed videos pertinent to a given textual query. Existing retrieval systems tend to rely on retrieval bias as a shortcut and thus, fail to sufficiently learn multi-modal interactions between query and video. This retrieval bias stems from learning frequent co-occurrence patterns between query and moments, which spuriously correlate objects (e.g., a pencil) referred in the query with moments (e.g., scene of writing with a pencil) where the objects frequently appear in the video, such that they converge into biased moment predictions. Although recent debiasing methods have focused on removing this retrieval bias, we argue that these biased predictions sometimes should be preserved because there are many queries where biased predictions are rather helpful. To conjugate this retrieval bias, we propose a Selective Query-guided Debiasing network (SQuiDNet), which incorporates the following two main properties: (1) Biased Moment Retrieval that intentionally uncovers the biased moments inherent in objects of the query and (2) Selective Query-guided Debiasing that performs selective debiasing guided by the meaning of the query. Our experimental results on three moment retrieval benchmarks (i.e., TVR, ActivityNet, DiDeMo) show the effectiveness of SQuiDNet and qualitative analysis shows improved interpretability.

description: This paper focuses on the dense uniform Li-Yorke chaos for linear operators on a Banach space. Some sufficient conditions and equivalent conditions are established under which the dynamical system is densely uniformly Li-Yorke chaotic. It is shown that there are plenty of densely uniformly Li-Yorke chaotic operators. For unilateral backward weighted shifts and bilateral backward weighted shifts on $\ell^p$, it is shown that Li-Yorke chaos is equivalent to dense uniform Li-Yorke chaos.

The elastic constants, Vickers hardness and shear strength are evaluated by means of first principle computer simulations on the basis of density functional theory. The results of simulations suggest a possibility of existence of several orthorhombic boron carbide phases with strongly enhanced mechanical properties with the Young modulus and Vickers hardness being within the range of 550-600 GPa and 43-50 GPa, respectively

description: We report fully relativistic molecular-dynamics simulations that verify the appearance of thermal equilibrium of a classical gas inside a uniformly accelerated container. The numerical experiments confirm that the local momentum distribution in this system is very well approximated by the Jüttner function -- originally derived for a flat spacetime -- via the Tolman-Ehrenfest effect. Moreover, it is shown that when the acceleration or the container size is large enough, the global momentum distribution can be described by the so-called modified Jüttner function, which was initially proposed as an alternative to the Jüttner function.

description: My artwork is an exploration of abstract mark-making that arises from a contemplation of the relationship between the individual and the landscape. This connects my work with a form of ecological thinking referred to as ecopsychology; a concept which offers me the freedom to explore patterns in nature while remaining purposefully connected to environmental concerns. My drawing process is thus informed by patterns in earth, sea, and sky, by the mark-making process itself and by the human detritus that pollutes, but is nevertheless a part of, the landscape as I encounter it. All of this feeds into the cycle of drawn acts. The abstraction of my drawn forms resolves into a more material practice in my sculptures which make use of found objects and evoke the entanglements that characterise the ecology of the contemporary world. In this way, my art making suggests modes of thought, encompassing all aspects of the environment, which are required to open space for ecological action.

This criterion leads us to a complete classification of the symmetric pairs $(G,G')$ having finite-dimensional Shintani spaces. A geometric criterion for uniform boundedness of $dim Sh(λ, ν)$ is also obtained. Furthermore, we prove that symmetry breaking operators of the restriction of smooth admissible representations yield Shintani functions of moderate growth, of which the dimension is determined for $(G, G') = (O(n+1,1), O(n,1))$.

description: The grid-to-rod fretting (GTRF) problem in pressurized water reactors is a flow-induced vibration problem that results in wear and failure of the fuel rods in nuclear assemblies. In order to understand the fluid dynamics of GTRF and to build an archival database of turbulence statistics for various configurations, implicit large-eddy simulations of time-dependent single-phase turbulent flow have been performed in 3x3 and 5x5 rod bundles with a single grid spacer. To assess the computational mesh and resolution requirements, a method for quantitative assessment of unstructured meshes with no-slip walls is described. The calculations have been carried out using Hydra-TH, a thermal-hydraulics code developed at Los Alamos for the Consortium for Advanced Simulation of Light water reactors, a United States Department of Energy Innovation Hub. Hydra-TH uses a second-order implicit incremental projection method to solve the single-phase incompressible Navier-Stokes equations. The simulations explicitly resolve the large scale motions of the turbulent flow field using first principles and rely on a monotonicity-preserving numerical technique to represent the unresolved scales. Each series of simulations for the 3x3 and 5x5 rod-bundle geometries is an analysis of the flow field statistics combined with a mesh-refinement study and validation with available experimental data. Our primary focus is the time history and statistics of the forces loading the fuel rods. These hydrodynamic forces are believed to be the key player resulting in rod vibration and GTRF wear, one of the leading causes for leaking nuclear fuel which costs power utilities millions of dollars in preventive measures. We demonstrate that implicit large-eddy simulation of rod-bundle flows is a viable way to calculate the excitation forces for the GTRF problem.

Notes
This is the first record for Europe. Myrmoxenus algerianus is known from the Atlas and Rif mountains in Algeria (type locality) and Morocco (Cagniant 1968). Buschinger et al. (1990) found it in both deciduous and coniferous (cedar) forests at 400-2100 m a. s. l. It is an active enslaver, most often on Temnothorax spinosus (Forel, 1909), but also on T. curtulus (Santschi, 1929), T. gentilis (Santschi, 1923) and T. monjauzei (Cagniant, 1968) (Buschinger 1989). Up to now, M. ravouxi (André 1896) has been the only known Myrmoxenus species from Sicily (Schifani et al. 2021 a, Schifani 2022). Myrmoxenus algerianus differs from congeners in the shape of the ventral subpetiolar process (almost rectangular rather than almost triangular in M. kraussei), the pilosity of the thorax (shorter in M. algerianus than in M. kraussei) and the position and length of the propodeal spines compared to M. ravouxi (Cagniant and Espadaler 1997) (Fig. 3 a). The collected specimen in Sicily was found in a karst gorge by leaf-litter sifting (Fig. 3 b). Although we have no information on the host from the new locality, none of the known host species from Morocco and Algeria occurs in Sicily. The following Temnothorax species were identified from the new locality: T. recedens (Nylander, 1853), T. poldii Alicata, Schifani & Prebus, 2022 and T. lichtensteini (Bondroit, 1918).

Meridional Circulation From Differential Rotation in an Adiabatically Stratified Solar/Stellar Convection Zone

Year: 2013
Subjects: subject: Solar and Stellar Astrophysics (astro-ph.SR)
subject: FOS: Physical sciences

description: Meridional circulation in stellar convection zones is not generally well observed, but may be critical for MHD dynamos. Coriolis forces from differential rotation (DR) play a large role in determining what the meridional circulation is. Here we consider whether a stellar DR that is constant on cylinders concentric with the rotation axis can drive a meridional circulation.Conventional wisdom says that it can not. Using two related forms of governing equations that respectively estimate the longitudinal components of the curl of meridional mass flux and the vorticity, we show that such DR will drive a meridional flow. This is because to satisfy anelastic mass conservation, non-spherically symmetric pressure contours must be present for all DRs, not just ones that depart from constancy on cylinders concentric with the rotation axis. Therefore the fluid is always baroclinic if DR is present, because, in anelastic systems, the perturbation pressure must satisfy a Poisson type equation, as well as an equation of state and a thermodynamic equation. We support our qualitative reasoning with numerical examples, and show that meridional circulation is sensitive to the magnitude and form of departures from rotation constant on cylinders. The effect should be present in 3D global anelastic convection simulations, particularly those for which the DR driven by global convection is nearly cylindrical in profile. For solar-like DR, Coriolis forces generally drive a two-celled circulation in each hemisphere, with a second, reversed flow at high latitudes. For solar like turbulent viscosities, the meridional circulation produced by Coriolis forces is much larger than observed on the Sun. Therefore there must be at least one additional force, probably a buoyancy force, which opposes the meridional flow to bring its amplitude down to observed values.

Camelus dromedarius

description: Camelus dromedarius Linnaeus, 1758. Syst. Nat., 10th ed., 1:65. TYPE LOCALITY: "Africa," deserts of Libya and Arabia, (domesticated stock). DISTRIBUTION: Extinct in the wild and unknown as fossil; domesticated in North Africa, Arabia, Mediterranean, Balkans, and Middle East; introduced into Australia. COMMENT: Produces fertile hybrids with bactrianus; though their distributions merge, breeding is regulated (as all individuals are domesticated in the zone of contact) (IUK). Corbet, 1978:197, citing Gray, 1954, stated that male hybrids are sterile. Bohldeen, 1961, Z. Tierzucht. Zuchtungsbiol., 76:107- 113, considered dromedarius a synonym of bactrianus.

description: In this paper we revisit stencil methods on GPUs in the context of exponential integrators. We further discuss boundary conditions, in the same context, and show that simple boundary conditions (for example, homogeneous Dirichlet or homogeneous Neumann boundary conditions) do not affect the performance if implemented directly into the CUDA kernel. In addition, we show that stencil methods with position-dependent coefficients can be implemented efficiently as well. As an application, we discuss the implementation of exponential integrators for different classes of problems in a single and multi GPU setup (up to 4 GPUs). We further show that for stencil based methods such parallelization can be done very efficiently, while for some unstructured matrices the parallelization to multiple GPUs is severely limited by the throughput of the PCIe bus.

description: Using a generalized Madelung transformation, we derive the hydrodynamic representation of the Dirac equation in arbitrary curved space-times coupled to an electromagnetic field. We obtain Dirac-Euler equations for fermions involving a continuity equation and a first integral of the Bernoulli equation. Comparing between the Dirac and Klein-Gordon equations we obtain the balance equation for fermion particles. We also use the correspondence between fermions and bosons to derive the hydrodynamic representation of the Weyl equation which is a chiral form of the Dirac equation.

Notes
This is the first record for Albania and the first member of Myrmoxenus for this country. It is widespread in Europe (missing in northern parts) to eastern Turkey (Schulz and Sanetra 2002). It is an active slave-maker, most often on Temnothorax unifasciatus (Latreille, 1798) (Buschinger and Winter 1985, Schulz and Sanetra 2002), but depending on the local fauna, it can also be found in nests of T. affinis (Mayr, 1855), T. albipennis (Curtis, 1854), T. tuberum (Fabricius, 1775) and T. nadigi (Kutter, 1925) (Czechowski and Czechowska 2000, Seifert 2018). The new finding of M. ravouxi is from a nest of T. unifasciatus in a pine forest in the Ostrovicë Mountain (southern Albania).

description: Quantum algorithms for simulation of Hamiltonian evolution are often based on product formulae. The fractal methods give a systematic way to find arbitrarily high-order product formulae, but result in a large number of exponentials. On the other hand, product formulae with fewer exponentials can be found by numerical solution of simultaneous nonlinear equations. It is also possible to reduce the cost of long-time simulations by processing, where a kernel is repeated and a processor need only be applied at the beginning and end of the simulation. In this work, we found thousands of new product formulae, and numerically tested these formulae, together with many formulae from prior literature. We provide methods to fairly compare product formulae of different lengths and different orders. For the case of 8th order, we have found new product formulae with exceptional performance, about two orders of magnitude better accuracy than prior work, both in the processed and non-processed cases. The processed product formula provides the best performance due to being shorter than the non-processed product formula. It outperforms all other tested product formulae over a range of many orders of magnitude in system parameters $T$ (time) and $ε$ (allowable error). That includes reasonable combinations of parameters to be used in quantum algorithms, where the size of the simulation is large enough to be classically intractable, but not so large it takes an impractically long time on a quantum computer.

description: A first order phase transition between a BCS phase and an insulating Mott phase for a gas of spatially separated electrons and holes with tunable Coulomb interaction and variable density is predicted. In the framework of a BCS-like mean-field approach and a Landau expansion in terms of the pairing order parameter the phase diagram is studied. This indicates several phases and phase transitions, including an electron-hole plasma at low density and weak interaction, an intermediate BCS phase with Cooper pairs and an electron-hole plasma at high density and weak interaction. The insulating Mott phase appears for the strong interaction and low temperatures. We briefly discuss the possibilities to realize these phases in realistic systems such as coupled quantum wells and graphene double layers.

description: More than a thousand exoplanets have been discovered over the last decade. Perhaps more excitingly, probing their atmospheres has become possible. With current data we have glimpsed the diversity of exoplanet atmospheres that will be revealed over the coming decade. However, numerous questions concerning their chemical composition, thermal structure, and atmospheric dynamics remain to be answered. More observations of higher quality are needed. In the next years, the selection of a space-based mission dedicated to the spectroscopic characterization of exoplanets would revolutionize our understanding of the physics of planetary atmospheres. Such a mission was proposed to the ESA cosmic vision program in 2014. Our paper is therefore based on the planned capabilities of the Exoplanet Characterization Observatory (EChO), but it should equally apply to any future mission with similar characteristics. With its large spectral coverage ($4-16\, \rm{μm}$), high spectral resolution ($Δλ/λ>300$ below $5\,\rm{μm}$ and $Δλ/λ>30$ above $5\,\rm{μm}$) and $1.5\rm{m}$ mirror, a future mission such as EChO will provide spectrally resolved transit lightcurves, secondary eclipses lightcurves, and full phase curves of numerous exoplanets with an unprecedented signal-to-noise ratio. In this paper, we review some of today's main scientific questions about gas giant exoplanets atmospheres, for which a future mission such as EChO will bring a decisive contribution.

description: The firewall paradox is often presented as arising from double entanglement, but I argue that more generally the paradox is double purity. Near-horizon modes are purified by the interior, in the infalling vacuum. Hence they cannot also be pure alone, or in combination with any third system, as demanded by unitarity. This conflict arises independently of the Page time, for entangled and for pure states. It implies that identifications of Hilbert spaces cannot resolve the paradox. Traditional complementarity requires the unitary identification of infalling matter with a scrambled subsystem of the Hawking radiation. Extending this map to the infalling vacuum overdetermines the out-state. More general complementarity maps ("A=R_B", "ER=EPR") founder when the near-horizon zone is pure. I argue that pure-zone states span the microcanonical ensemble, and that this suffices to make the horizon a special place. I advocate that the ability to detect the horizon locally, rather than the degree or probability of violence, is what makes firewalls problematic. Conversely, if the production of matter at the horizon can be dynamically understood and shown to be consistent, then firewalls do not constitute a violation of the equivalence principle.

Energy budget of the bifurcated component in the radio pulsar profile of PSR J1012+5307

description: The bifurcated emission component (BEC) in the radio profile of the millisecond pulsar J1012+5307 can be interpreted as the signature of the curvature radiation beam polarised orthogonally to the plane of electron trajectory. Since the beam is intrinsically narrow (~1 deg), the associated emission region must be small for the observed BEC to avoid smearing out by spatial convolution. We estimate whether the energy available in the stream is sufficient to produce such a bright feature in the averaged profile. The energy considerations become complicated by the angular constraints imposed by the width of the microbeam, and by the specific spectrum of the BEC which is found to have the spectral index xi ~ -0.9 in comparison to the index of xi ~ -2 for the total profile. For typical parameters, the luminosity of the BEC is determined to be 4 10^{25} erg/s, whereas the maximum-possible beam-size-limited power of the stream is L_max ~ 2 10^{29} erg/s. This implies the minimum energy-conversion efficiency of eta ~ 2 10^{-4}. The BEC's luminosity does not exceed any absolute limits of energetics, in particular, it is smaller than the power of primary electron and/or secondary plasma stream. However, the implied efficiency of energy transfer into the radio band is extreme if the coherently emitting charge-separated plasma density is limited to the Goldreich-Julian value. This suggests that the bifurcated shape of the BEC has macroscopic origin, however, several uncertainties (eg. the dipole inclination and spectral shape) make this conclusion not firm.
