 Comments
 This arrangement was suggested in a previous report (Moraes et al., 2010), but could not be supported because of the limited taxa sampling, particularly for species that were earlier included in the genus Lapaeumides. Now, with a more complete sampling, a number of synapomorphic characters agree with this arrangement: (i) subapical band on forewing as a triangle (15: 3); (ii) ventral margin of valva oblique (53: 1); (iii) bulla seminalis globular (88: 2); and (iv) bulla seminalis with sclerotized plates (90: 1).
 The wing pattern is similar in all species, except for S. amycus (Fig. 32). Moreover, the wing pattern is so similar in S. hegemon and S. zerynthia that we wonder why no one has previously attempted to assess the morphology of these two species and to synonymize them.

description: In this paper the Rayleigh-Taylor instability (RTI) along the density interfaces of gravity-current fronts is analyzed. Both the location and the spanwise wavenumber of the most unstable mode determined by the local dispersion relation agree with those of the strongest perturbation obtained from numerical simulations, suggesting that the original formation mechanism of lobes and clefts at the current front is RTI. Furthermore, the predictions of the semi-infinite RTI model, i.e. the original dominating spanwise wavenumber of the Boussinesq current substantially depends on the Prandtl number and has a 1/3 scaling law with the Grashof number, are confirmed by the three-dimensional numerical simulations.

Notosolenus hemicircularis

description: Notosolenus hemicircularis Lee and Patterson, n. sp.
(fi gures 9d, 10i -l. Type micrograph: fi gure 10i)
 Diagnosis. Notosolenus, 9-10 Mm long, 6-7 Mm wide, ventrally fl attened, with a semicircular hyaline collar around a short neck and with fi ve dorsal keels and three fi ne ventral ridges.
 Description. Colourless, 9-10 Mm long and 6-7 Mm wide, ventrally fl attened and dorsally convex. Both ends of the cell are pointed but there is a hyaline semicircular collar around the short anterior neck. This species has fi ve dorsal keels running along the cell. Ventrally there are three fi ne ridges. The right and left ventral ridges arise at the neck. The left ventral ridge curves slightly from the anterior to the posterior forming an arc. The mid-ventral ridge arises from a small protrusion near the anterior end of the cell. Two are unequal in length and are slightly thickened. The anterior fl agellum is about 1.2-1.4 times the length of the cell and the recurrent posterior fl agellum is about 0.5-1.0 times the cell length. The reservoir lies anteriorly in the right-hand side of the cell and the nucleus in the left-hand side. Moves by gliding. Rarely observed.
 Remarks. This species has the characteristics of the genus Notosolenus in that it is a heterotrophic euglenid with a rigid, fl attened body, two emergent fl agella and no visible mouth, and moves by gliding. This species can be distinguished from other small species of Notosolenus such as N. apocamptus Stokes, 1884 and N. rhombicus Larsen, 1987 by the semicircular hyaline collar and the fi ve dorsal keels (see Huber-Pestalozzi, 1955; Larsen, 1987). Notosolenu s hemicircularis is similar in general shape to N. papilio Skuja, 1939 and N. urceolatus Larsen and Patterson, 1990 (see Skuja, 1939; Larsen and Patterson, 1990), but it can be distinguished from both species by its smaller size and its strongly developed semicircular hyaline collar. Notosolenus papilio also has a ventral groove and lateral wings.

Emission-Line Eclipse Mapping of Velocity Fields in Dwarf-Nova Accretion Disk
Creators: name: Makita, Makoto

Publisher: name: arXiv
Year: 2002
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: We propose a new method, emission-line eclipse mapping, to map the velocity fields of an accretion disk in position space. Quiescent dwarf novae usually exhibit double-peaked emission line profiles because of disk rotation. Since a part of the disk having a different line-of-sight velocity is successively obscured by a companion in eclipsing systems, they show time-varying line profiles. We calculate time changes of the emission line profiles, assuming Keplerian rotation fields (v_ϕ\propto r^(-1/2) with r being the distance from the disk center) and the emissivity distribution of j \propto r^(-3/2). We, then, apply the usual eclipse mapping technique to the light curves at each of 12-24 wavelengths across the line center to map the region with the same line-of-sight velocity. The reconstructed images typically exhibit a `two-eye' pattern for high line-of-sight velocities and we can recover the relation, v_ϕ\propto d^(-1/2), on the assumption of the axisymmetric disk, where d is the separation between the two `eyes'. We will be able to probe the Keplerian rotation law, the most fundamental assumption adopted in many disk models, by high-speed spectroscopic observations with 8-m class telescopes.

description: We describe how simple machine learning methods successfully predict geometric properties from Hilbert series (HS). Regressors predict embedding weights in projective space to ${\sim}1$ mean absolute error, whilst classifiers predict dimension and Gorenstein index to $>90\%$ accuracy with ${\sim}0.5\%$ standard error. Binary random forest classifiers managed to distinguish whether the underlying HS describes a complete intersection with high accuracies exceeding $95\%$. Neural networks (NNs) exhibited success identifying HS from a Gorenstein ring to the same order of accuracy, whilst generation of 'fake' HS proved trivial for NNs to distinguish from those associated to the three-dimensional Fano varieties considered.

description: We examine carefully the rationale underlying the approaches to belief change taken in the literature, and highlight what we view as methodological problems. We argue that to study belief change carefully, we must be quite explicit about the ``ontology'' or scenario underlying the belief change process. This is something that has been missing in previous work, with its focus on postulates. Our analysis shows that we must pay particular attention to two issues that have often been taken for granted: The first is how we model the agent's epistemic state. (Do we use a set of beliefs, or a richer structure, such as an ordering on worlds? And if we use a set of beliefs, in what language are these beliefs are expressed?) We show that even postulates that have been called ``beyond controversy'' are unreasonable when the agent's beliefs include beliefs about her own epistemic state as well as the external world. The second is the status of observations. (Are observations known to be true, or just believed? In the latter case, how firm is the belief?) Issues regarding the status of observations arise particularly when we consider iterated belief revision, and we must confront the possibility of revising by p and then by not-p.

 Comments
 This group was the subject of a recent revisionary study (Moraes et al., 2011), which showed that the species have distinctive characters that corroborate the genus status: (i) discal band extending to M 2 (19: 2); (ii) subterminal part of aedeagus wall with spines implanted on a sclerotized plate (35: 1); (iii) valva with a tooth-like corona near the posterior margin (57: 1); and (iv) eighth tergite in females with the lateral margin sinuous (109: 3).
The following genera were not included in this analysis because of a lack of material, and for this reason we maintained the species in the nominative genus, with no taxonomic modification.

description: Classifiers label data as belonging to one of a set of groups based on input features. It is challenging to obtain accurate classification performance when the feature distributions in the different classes are complex, with nonlinear, overlapping and intersecting supports. This is particularly true when training data are limited. To address this problem, this article proposes a new type of classifier based on obtaining a local approximation to the support of the data within each class in a neighborhood of the feature to be classified, and assigning the feature to the class having the closest support. This general algorithm is referred to as LOcal Manifold Approximation (LOMA) classification. As a simple and theoretically supported special case having excellent performance in a broad variety of examples, we use spheres for local approximation, obtaining a SPherical Approximation (SPA) classifier. We illustrate substantial gains for SPA over competitors on a variety of challenging simulated and real data examples.

description: The optical (BVRI) and radio (8.4 GHz) light curves of S5 1803+784 on a time span of nearly 6 years are presented and discussed. The optical light curve showed an overall variation greater than 3 mag, and the largest changes occured in three strong flares. No periodicity was found in the light curve on time scales up to a year. The variability in the radio band is very different, and shows moderate oscillations around an average constant flux density rather than relevant flares, with a maximum amplitude of $\sim$30%, without a simultaneous correspondence between optical and radio luminosity. The optical spectral energy distribution was always well fitted by a power law. The spectral index shows small variations and there is indication of a positive correlation with the source luminosity. Possible explanations of the source behaviour are discussed in the framework of current models.

description: TreeSPH simulations of galaxy formation in a LCDM cosmology, with star formation, energetic stellar feedback and a meta-galactic UV field have been performed, resulting in realistic disk, S0 and E galaxies at z=0. The disk galaxies are deficient in angular momentum by only about a factor of two compared to observations for runs where fairly strong star-bursts in early, proto-galactic clouds lead to "blow-away" of the remaining gas. The surface density profiles of the stellar disks are approximately exponential and those of the bulges range from exponential to r^(1/4). B/D ratios and integrated B-V colours are consistent with observations. The observed I-band TF relation can be matched with M/L_I ~ 0.8, in fair agreement with recent determinations. The (E/S0)s have approximately r^(1/4) profiles, non disk-like kinematics and are flattened due to non-isotropic stellar velocity distributions. We predict hot halo gas to cool out and accrete onto the Galactic disk at 0.5-1 Msun/yr at z=0, consistent with upper limits from FUSE observations of O VI. We analyzed two Milky Way-sized galaxies and find accretion rates, and X-ray halo luminosities, 6-7 times larger at z=1 than at z=0. The gas infall declines nearly exponentially with time, supporting the approximation often used in chemical evolution models. The infall time-scales are comparable to what is used to solve the "G-dwarf problem". One disk forms "inside-out", the other "outside-in". For both, the mean stellar ages in the outskirts agree with findings for the disk of M31. The amount of hot gas in disk galaxy haloes is consistent with observational upper limits, as are dispersion measures to pulsars in the globular cluster M53 and the LMC, which were "inserted" in the disk galaxy haloes.

(fi gures 9i, 10o, 11m)
 Description. Cell outline elongate ovate, 27 -56 Mm long, 15-24 Mm wide, the ratio of length to width is 1.5 to 3.2. Dorso-ventrally fl attened, dorsally with a median longitudinal groove, and ventrally a wide groove and four fi ne stripes. With a small obliquely oriented ingestion organelle with two fi ne rods near the anterior. The majority of the cells have a rounded posterior end but some cells have a slightly pointed posterior end. The reservoir is anteriorly situated in the right side of the cell and the nucleus in the left side. Two fl agella of unequal length; the anterior fl agellum is as long as the cell, held forward in gliding cells. The posterior fl agellum is about 0.2-0.6 times the length of the cell. The organism contained eukaryotic algal material up to 8 Mm long. Moves by smooth gliding with the anterior fl agellum. Common in late culture. Description based on observations of 30 cells.
 Remarks. Previously reported lengths of cells from marine sites (subtropical and tropical Australia, Brazil, Fiji, Hawaii and Panama) range from 24 to 40 Mm (Larsen and Patterson, 1990; Ekebom et al., 1996; Patterson and Simpson, 1996). Our observations extend the size range. We observed two cells measuring 43 and 56 Mm which may be assignable to N. ostium. Notosolenus ostium is easily distinguished from other species of Notosolenus by its deep dorsal groove and visible ingestion organelle, which has not been seen in other species of the genus except N. triangularis Larsen and Patterson, 1990. Notosolenus ostium is similar to N. lagenos Skuja, 1948 in length and general appearance and in having a very short recurrent fl agellum, but N. ostium can be distinguished by its wide grooves on both faces of the cell.

description: Along with the development of modern computing technology and social sciences, both theoretical research and practical applications of social computing have been continuously extended. In particular with the boom of artificial intelligence (AI), social computing is significantly influenced by AI. However, the conventional technologies of AI have drawbacks in dealing with more complicated and dynamic problems. Such deficiency can be rectified by hybrid human-artificial intelligence (H-AI) which integrates both human intelligence and AI into one unity, forming a new enhanced intelligence. H-AI in dealing with social problems shows the advantages that AI can not surpass. This paper firstly introduces the concept of H-AI. AI is the intelligence in the transition stage of H-AI, so the latest research progresses of AI in social computing are reviewed. Secondly, it summarizes typical challenges faced by AI in social computing, and makes it possible to introduce H-AI to solve these challenges. Finally, the paper proposes a holistic framework of social computing combining with H-AI, which consists of four layers: object layer, base layer, analysis layer, and application layer. It represents H-AI has significant advantages over AI in solving social problems.

description: We study the group of extensions in the category of Drinfeld modules and Anderson's t-modules, and we show in certain cases that this group can itself be given the structure of a t-module. Our main result is a Drinfeld module analogue of the Weil-Barsotti formula for abelian varieties. Extensions of general t-modules are also considered, in particular extensions of tensor powers of the Carlitz module. We motivate these results from various directions and compare to the situation of elliptic curves.

North--South Asymmetry in Solar Activity and Solar Cycle Prediction, IV: Prediction for Lengths of Upcoming Solar Cycles

description: We analyzed the daily sunspot-group data reported by the Greenwich Photoheliographic Results (GPR) during the period 1874-1976 and Debrecen Photoheliographic Data (DPD) during the period 1977-2017 and studied North-South asymmetry in the maxima and minima of the Solar Cycles 12-24. We derived the time series of the 13-month smoothed monthly mean corrected whole-spot areas of the sunspot groups in the Sun's whole sphere (WSGA), northern hemisphere (NSGA), and southern hemisphere (SSGA). From these smoothed time series we obtained the values of the maxima and minima, and the corresponding epochs, of the WSGA, NSGA, and SSGA Cycles 12-24. We find that there exists a 44-66 years periodicity in the North-South asymmetry of the minimum. A long periodicity (130-140 years) may exist in the asymmetry of the maximum. A statistically significant correlation exists between the maximum of SSGA Cycle n and the rise time of WSGA Cycle n + 2. A reasonably significant correlation also exists between the maximum of WSGA Cycle n and the decline time of WSGA Cycle n + 2. These relations suggest that the solar dynamo carries memory over at least three solar cycles. Using these relations we obtained the values 11.7 + or - 0.15 years, 11.2 + or - 0.2 years, and 11.45 + or - 0.3 years for the lengths of WSGA Cycles 24, 25, and 26, respectively, and hence, July 2020, October 2031, and March 2043 for the minimum epochs (start dates) of WSGA Cycles 25, 26, and 27, respectively. We also obtained May 2025 and March 2036 for the maximum epochs of WSGA Cycles 25 and 26, respectively. It seems during the late Maunder minimum sunspot activity was absent around the epochs of the maxima of the NSGA-cycles and the minima of the SSGA-cycles, and some activity was present at the epochs of the maxima of some SSGA-cycles and the minima of some NSGA-cycles.

description: The electronic nematic phase, wherein electronic degrees of freedom lower the crystal rotational symmetry, is a common motif across a number of high-temperature superconductors. However, understanding the role and influence of nematicity and nematic fluctuations in Cooper pairing is often complicated by the coexistence of other orders, particularly long-range magnetic order. Here we report the enhancement of superconductivity in a model electronic nematic system absent of magnetism, and show that the enhancement is directly born out of strong nematic fluctuations emanating from a tuned quantum phase transition. We use elastoresistance measurements of the Ba$_{1-x}$Sr$_{x}$Ni$_2$As$_2$ substitution series to show that strontium substitution promotes an electronically driven $B_{1g}$ nematic order in this system, and that the complete suppression of that order to absolute zero temperature evokes a dramatic enhancement of the pairing strength, as evidenced by a sixfold increase in the superconducting transition temperature. The direct relation between enhanced pairing and nematic fluctuations in this model system, as well as the interplay with a unidirectional charge density wave order comparable to that found in the cuprates, offers a means to elucidate the role of nematicity in boosting superconductivity.

description: Simulating quantum dynamics is expected to be performed more easily on a quantum computer than on a classical computer. However, the currently available quantum devices lack the capability to implement fault-tolerant quantum algorithms for quantum simulation. Hybrid classical quantum algorithms such as the variational quantum algorithms have been proposed to effectively use current term quantum devices. One promising approach to quantum simulation in the noisy intermediate-scale quantum (NISQ) era is the diagonalisation based approach, with some of the promising examples being the subspace Variational Quantum Simulator (SVQS), Variational Fast Forwarding (VFF), fixed-state Variational Fast Forwarding (fs-VFF), and the Variational Hamiltonian Diagonalisation (VHD) algorithms. However, these algorithms require a feedback loop between the classical and quantum computers, which can be a crucial bottleneck in practical application. Here, we present the Classical Quantum Fast Forwarding (CQFF) as an alternative diagonalisation based algorithm for quantum simulation. CQFF shares some similarities with SVQS, VFF, fs-VFF and VHD but removes the need for a classical-quantum feedback loop and controlled multi-qubit unitaries. The CQFF algorithm does not suffer from the barren plateau problem and the accuracy can be systematically increased. Furthermore, if the Hamiltonian to be simulated is expressed as a linear combination of tensored-Pauli matrices, the CQFF algorithm reduces to the task of sampling some many-body quantum state in a set of Pauli-rotated bases, which is easy to do in the NISQ era. We run the CQFF algorithm on existing quantum processors and demonstrate the promise of the CQFF algorithm for current-term quantum hardware. Our work provides a $10^4$ improvement over the previous record.

description: It is shown that the Clifford superalgebra Cl(n|m) generated by m pairs of Bose operators (odd elements) anticommuting with n pairs of Fermi operators (even elements) can be deformed to Cl_q(n|m) such that the latter is a homomorphic image of the quantum superalgebra U_q[osp(2n+1|2m)]. The Fock space F(n|m) of Cl_q(n|m) is constructed. At q being a root of unity (q=\exp ({iπl/k})) q-bosons (and q-fermions) are operators acting in a finite-dimensional subspace F_{l/k}(n|m) of F(n|m). Each F_{l/k}(n|m) is turned through the above mentioned homomorphism into an irreducible (root of unity) U_q[osp(2n+1|2m)] module. For q being a primitive root of unity (l=1) the corresponding representation is unitary. The module F_{1/k}(n|m) is decomposed into a direct sum of irreducible U_q[sl(m|n)] submodules. The matrix elements of all Cartan-Weyl elements of U_q[sl(m|n)] are given within each such submodule.

description: We sought to determine the scale of scintillation in the interstellar plasma of PSR J0437-4715. We used the Very Long Baseline Array to obtain scintillation amplitude and phase data, from dynamic spectra at 327 MHz. We observe two scales of scintillation of pulsar PSR J0437-4715, differing by more than an order of magnitude in scintillation bandwidth. The wider-bandwidth scale of scintillation that we observe indicates less scattering for this pulsar than for other nearby pulsars, except for PSR B0950+08.

description: An important issue in developing quantum technology is that quantum states are so sensitive to noise. We propose a protocol that introduces reverse dynamics, in order to precisely control quantum systems against noise described by the Lindblad master equation. The reverse dynamics can be obtained by constructing the Petz recovery map in continuous time. By providing the exact form of the Hamiltonian and jump operators for the reverse dynamics, we explore the potential of utilizing the near-optimal recovery of the Petz map in controlling noisy quantum dynamics. While time-dependent dissipation engineering enables us to fully recover a single quantum trajectory, we also design a time-independent recovery protocol to protect encoded quantum information against decoherence. Our protocol can efficiently suppress only the noise part of dynamics thereby providing an effective unitary evolution of the quantum system.

description: We present a map between the tree-level Standard Model Effective Theory (SMEFT) in the Warsaw basis and massive on-shell amplitudes. As a first step, we focus on the electroweak sector without fermions. We describe the Feynman rules for a particular choice of input scheme and compare them with the 3-point massive amplitudes in the broken phase. Thereby we fix an on-shell basis which allows us to study scattering amplitudes with recursion relations. We hope to open up new avenues of exploration to a complete formulation of massive EFTs in the on-shell language.

description: The muon intensity and angular distribution in the shallow-underground laboratory Felsenkeller in Dresden, Germany have been studied using a portable muon detector based on the close cathode chamber design. Data has been taken at four positions in Felsenkeller tunnels VIII and IX, where a new 5 MV underground ion accelerator is being installed, and in addition at four positions in Felsenkeller tunnel IV, which hosts a low-radioactivity counting facility. At each of the eight positions studied, seven different orientations of the detector were used to compile a map of the upper hemisphere with 0.85° angular resolution. The muon intensity is found to be suppressed by a factor of 40 due to the 45 m thick rock overburden, corresponding to 140 meters water equivalent. The angular data are matched by two different simulations taking into account the known geodetic features of the terrain: First, simply by determining the cutoff energy using the projected slant depth in rock and the known muon energy spectrum, and second, in a Geant4 simulation propagating the muons through a column of rock equal to the known slant depth. The present data are instrumental for studying muon-induced effects at these depths and also in the planning of an active veto for accelerator-based underground nuclear astrophysics experiments.

(fi gures 14a, 15c -e)
 Description. Cell 12-22 Mm long, 8-19 Mm wide, narrow anteriorly, widest slightly posterior to midline. With lateral hyaline fl anges. This species has two dorsal keels which run along the entire cell; the right one is well developed. One narrow ventral groove with marginal ridges forming a double keel extends from the collar around the canal. One fl agellum emerges from the canal and is about 1.0-1.2 times the cell length. The reservoir is situated in the right anterior side of the cell and the nucleus lies near the midline and adjacent to the left margin of the cell. Moves by gliding. Commonly observed, but not abundant.
 Remarks. This species has been recently reported with lengths from 10 to 25 Mm from marine sites in subtropical and tropical Australia, Brazil and in the temperate Danish Wadden Sea (Larsen, 1987; Larsen and Patterson, 1990; Ekebom et al., 1996; Patterson and Simpson, 1996). Generally, our observations are in accord with those of Larsen and Patterson (1990) although in contrast to most authors (Klebs, 1893; Lemmermann, 1914; Shawhan and Jahn, 1947; Huber-Pestalozzi, 1955; Larsen, 1987; Ekebom et al., 1996; Patterson and Simpson, 1996), Larsen and Patterson (1990) described P. abscissa as having one dorsal keel. We found one cell with one dorsal keel and included the cell here, and surmise that the number of dorsal keels may not be a good diagnostic characteristic. This organism resembles a few species of the genus Petalomonas, such as P. spinifera Lee and Patterson, n. comb. (see below), P. mira var. bicarinata Skuja, 1939 and P. raiula Larsen and Patterson, 1990 in having a ventral ridged groove. Petalomonas abscissa can be distinguished by its elliptical, regular cell shape and the indented posterior end (P. spinifera, P. mira var. bicarinata and P. raiula have posterior protrusions). It resembles P. applanata Skuja, 1939 in general appearance, but it has a posterior indentation and is smaller than P. applanat a (30-36 Mm).

description: Hot electrons dominate the ultrafast ($\sim$fs-ps) optical and electronic properties of metals and semiconductors and they are exploited in a variety of applications including photovoltaics and photodetection. We perform power-dependent third harmonic generation measurements on gated single-layer graphene and detect a significant deviation from the cubic power-law expected for a third harmonic generation process. We assign this to the presence of hot electrons. Our results indicate that the performance of nonlinear photonics devices based on graphene, such as optical modulators and frequency converters, can be affected by changes in the electronic temperature, which might occur due to increase of absorbed optical power or Joule heating.

description: In this work, we investigate the optoelectronic properties of zinc oxide (ZnO) nanowires, which are good candidates for applications based on integrated optics. Single ZnO nanowire photodetectors were fabricated with ohmic contacts. By taking current transient measurements in different atmospheres (oxygen, air, vacuum and argon), and at various temperatures, we point out the importance of surface effects on the electrical behaviour. Results confirm that oxygen chemisorption is responsible for the existence of a high photoconductive gain in these devices, and for the first time a two step process in the photocurrent rise transient is reported. A maximum gain of $G=7.8 \times 10^{7}$ is achieved. However, under certain conditions, the persistence of the photocurrent can last up to several hours and as such may prevent the device from operating at useful rates. From a knowledge of the photocurrent response mechanisms, we establish a method to restore the photodetector to its initial state, with very low dark current, by applying an appropriate gate voltage sequence. This advances the state of the art for these detectors towards commercial applications.
