description: The Milky Way lies in a thin plane, the Local Sheet, a part of a wall bounding the Local Void lying toward the north supergalactic pole. Galaxies with accurate distances both above and below this supergalactic equatorial plane have systematically negative peculiar velocities. The interpretation of this situation is that the Local Void is expanding, giving members of the Local Sheet deviant velocities toward the south supergalactic pole. The few galaxies within the void are evacuating the void. Galaxies in a filament in the supergalactic south are not feeling the expansion so their apparent motion toward us is mainly a reflex of our motion. The model of the local velocity field was uncertain because the apex of our motion away from the Local Void lies in obscurity near the Galactic plane. Here, results of Hubble Space Telescope infrared observations are reported that find tip of the red giant branch distances to four obscured galaxies. All the distances are $\sim7$ Mpc, revealing that these galaxies are part of a continuous filamentary structure passing between the north and south Galactic hemispheres and sharing the same kinematic signature of peculiar velocities toward us. A fifth galaxy nearby in projection, GALFA-DW4, has an ambiguous distance. If nearby at $\sim 3$ Mpc, this galaxy has an anomalous velocity away from us of +348 km/s. Alternatively, perhaps the resolved stars are on the asymptotic giant branch and the galaxy is beyond 6 Mpc whence the observed velocity would not be unusual.

description: Many communication and social networks have power-law link distributions, containing a few nodes which have a very high degree and many with low degree. The high connectivity nodes play the important role of hubs in communication and networking, a fact which can be exploited when designing efficient search algorithms. We introduce a number of local search strategies which utilize high degree nodes in power-law graphs and which have costs which scale sub-linearly with the size of the graph. We also demonstrate the utility of these strategies on the Gnutella peer-to-peer network.

description: We report the optical identifications of two X-ray luminous point sources in the spiral galaxy NGC4565 based on archive data of Chandra and the Hubble Space Telescope. The central X-ray point source, RXJ1236.3+2559, is found to be the nucleus of NGC4565 with an X-ray luminosity of Lx= 4.3 10^{39} erg. We show that its multi-waveband properties are consistent with it being a low-luminosity active galactic nucleus. A faint optical counterpart with B=25.1 and I=24.0 was identified for the off-nucleus X-ray point source, RXJ1236.2+2558. Its extinction corrected B magnitude is estimated to be 24.5. The X-ray to optical flux ratio (fx/fB) is about 540. From the optical and X-ray properties we argue that RXJ1236.2+2558 is an ultra-luminous X-ray compact source with Lx=6.5 10^{39} erg. The source is probably located in a faint globular cluster at the outer edge of NGC4565's bulge.

 Comments
 This enigmatic species, restricted to Cuba and the Dominican Republic, has some idiosyncratic features, such as a heavily sclerotized plate dorsal to the anellus (transtila?), as well as the juxta and subscaphium heavily sclerotized, and the posterior arms of the gnathos fused together, enclosing the anal tube. Moreover, I. hecate shares some common features, such as the morphology of the gnathos, with the Telchin group, and plesiomorphic characters, such as the valva morphology, with Ceretes and Corybanthes. Concerning the forewing pattern, this genus has some patterns similar to G. decussata and the translucent subapical spots that are also present in Athis and Hista species, but these are homoplastic characters. The sister-group relationship with a suprageneric clade was considered in our decision to maintain this monotypic genus.

description: To study the effects of Online Social Network (OSN) activity on real-world offline events, researchers need access to OSN data, the reliability of which has particular implications for social network analysis. This relates not only to the completeness of any collected dataset, but also to constructing meaningful social and information networks from them. In this multidisciplinary study, we consider the question of constructing traditional social networks from OSN data and then present several measurement case studies showing how variations in collected OSN data affects social network analyses. To this end we developed a systematic com parison methodology, which we applied to five pairs of parallel datasets collected from Twitter in four case studies. We found considerable differences in several of the datasets collected with different tools and that these variations significantly alter the results of subsequent analyses. Our results lead to a set of guidelines for researchers planning to collect online data streams to infer social networks.

Matrix dissimilarities based on differences in moments and sparsity

description: Generating a dissimilarity matrix is typically the first step in big data analysis. Although numerous methods exist, such as Euclidean distance, Minkowski distance, Manhattan distance, Bray–Curtis dissimilarity, Jaccard similarity and Dice dissimilarity, it remains unclear which factors drive dissimilarity between groups. In this paper, we introduce an approach based on differences in moments and sparsity. We show that this method can delineate the key factors underlying group differences. For example, in biology, mean dissimilarity indicates differences driven by up/down-regulated gene expressions, standard deviation dissimilarity reflects the heterogeneity of response to treatment, and sparsity dissimilarity corresponds to differences prompted by the activation/silence of genes. Through extensive reanalysis of transcriptome, proteome, metabolome, immune profiling, microbiome, and social science datasets, we demonstrate insights not captured in previous studies. For instance, without considering metadata such as age, BMI, sex, or biomarkers, it is feasible to predict COVID-19 patient mortality based solely on matrix dissimilarities observed during the first week with high accuracy.

 Comments
This genus arrangement is supported by the eighth tergite, in females, divided on the posterior margin. Moreover, the absence of a discal band on the forewing, the posterior portion of the gnathos lacking an anterior extension, and the sensilla on the female eighth tergite are also diagnostic characters for this group.
 This genus includes some of the most remarkable mimetic species of Heliconiinae (Nymphalidae), except for P. cochrus (Fig. 13), which resembles some species of the genus Mimoides (Papilionidae). Although it is tempting to hypothesize that these patterns originated from a common ancestor, which is corroborated by other morphological characters, this supposition is not easy to defend because the patterns are so different (Figs 9–12), and probably evolved several times in this lineage. Such diverse patterns led to the establishment of several subspecies for some species included in this genus. These were erected based only on the type locality and slight differences in the wing pattern, without any further investigations or compilation of geographical data in order to establish the true range of distribution for the different populations, which apparently have a very restricted niche.
 The species of this group included in our analysis, except P. cochrus (Fig. 124), have the inner surface of the bulla seminalis densely covered by micropapillae (Fig. 126), which seems to be a diagnostic character. The morphology of the micropapillae shows significant differences. In P. cochrus these are smaller and flattened (Fig. 124), and in the other species analysed they are larger and cylindrical (127).

description: From both global and local perspectives, there are strong reasons to promote energy efficiency. These reasons have prompted leaders in the European Union (EU) and countries of the Middle East and North Africa (MENA) to adopt policies to move their citizenry toward more efficient energy consumption. Energy efficiency policy is typically framed at the national, or transnational level. Policy makers then aim to incentivize microeconomic actors to align their decisions with macroeconomic policy. We suggest another path towards greater energy efficiency: Highlighting individual benefits at microeconomic level. By simulating lighting, heating and cooling operations in a model single-family home equipped with modest automation, we show that individual actors can be led to pursue energy efficiency out of enlightened self-interest. We apply simple-to-use, easily, scalable impact indicators that can be made available to homeowners and serve as intrinsic economic, environmental and social motivators for pursuing energy efficiency. The indicators reveal tangible homeowner benefits realizable under both the market-based pricing structure for energy in Germany and the state-subsidized pricing structure in Algeria. Benefits accrue under both the continental climate regime of Germany and the Mediterranean regime of Algeria, notably in the case that cooling energy needs are considered. Our findings show that smart home technology provides an attractive path for advancing energy efficiency goals. The indicators we assemble can help policy makers both to promote tangible benefits of energy efficiency to individual homeowners, and to identify those investments of public funds that best support individual pursuit of national and transnational energy goals.

description: We use elementary methods to compute the L2-dimension of the eigenspaces of the Markov operator on the lamplighter group and of generalizations of this operator on other groups. In particular, we give a transparent explanation of the spectral measure of the Markov operator on the lamplighter group found by Grigorchuk-Zuk. The latter result was used by Grigorchuk-Linnell-Schick-Zuk to produce a counterexample to a strong version of the Atiyah conjecture about the range of L2-Betti numbers. We use our results to construct manifolds with certain L2-Betti numbers (given as convergent infinite sums of rational numbers) which are not obviously rational, but we have been unable to determine whether any of them are irrational.

description: Notosolenus adamas Lee and Patterson, n. sp.
(fi gures 9a, 10a, b. Type micrograph: fi gure 10b)
 Diagnosis. Notosolenus, cell diamond-shaped about 14 Mm long and 9-12 Mm wide, with a narrow ventral groove.
 Description. Colourless euglenid with diamond-shaped or rhomboid hyaline body. About 14 Mm long and 9-12 Mm wide, dorso-ventrally fl attened. The anterior fl agellum is slightly longer than the cell. The posterior fl agellum is about 0.5 times the cell length and emerges subapically at the end of a narrow median ventral groove. The reservoir is situated in the right side of the cell and the nucleus is in the left side. Small granules are often seen under the cell surface. Cells move slowly by gliding with the anterior fl agellum directed anteriorly and with most motion at the tip of the anterior fl agellum which moves actively. Rarely observed.
 Remarks. This species has the characteristics of Notosolenus in being a rigid heterotrophic euglenid, being fl attened, and in having two fl agella emerging from a canal which opens subapically, moving by gliding, and with no visible mouth. It is distinguished from most other species of Notosolenus and Petalomonas by the cell shape. It is most similar to N. rhombicus Larsen, 1987. Larsen (1987) did not agree that the organisms referred to as N. obliquus (Klebs, 1893) Skuja, 1939 by Skuja (1939) were the same species as the organisms described for its basionym, Petalomona s inēxa var. obliqua Klebs, 1893. Larsen therefore provided a new name for the taxon observed by Skuja and himself. Notosolenu s adamas is distinguished from N. rhombicu s because the nucleus is not located posteriorly but near the equator and to the left, because it is fl at, and because there is no anterior collar. This species resembles N. papilio (see Skuja, 1939) from freshwater in general shape and in having no dorsal ridges. Notosolenus papilio also has a short anterior neck. Notosolenus pentagonu s (see Playfair, 1921) is similar to N. adamas in having a hyaline body, but is distinguished by its bigger size (about 21 Mm), long posterior fl agellum, and pentagonal cell shape. Notosolenus adamas resembles N. scutulum Larsen and Patterson, 1990 in size and in having a ventral groove, but can be distinguished because N. scutulum also has one deep dorsal groove. Notosolenus adamas is broadest in the middle of the cell, while N. scutulum is broader more posteriorly.

description: Even with several thousand {\it Fermi}-LAT blazar detections, the $γ$-ray emission mechanism is poorly understood. We explore correlated optical/$γ$-ray flux variations for 178 {\it Fermi}-LAT blazars regularly monitored by KAIT, SMARTS, and the Steward Observatory. Out of the 178 sources, 121 show a measurable ($>1σ$) discrete correlation function peak. Using the derived time-lags and Bayesian block light-curve decompositions, we measure the fraction of common and orphan flares between the two bands. After accounting for sampling and sensitivity limitations we quantify for the first time the true orphan flare rates of optical and $γ$-ray flares: 54.5\% of optical and 20\% of $γ$-ray flares are orphan events. Both the intraband temporal relation and the small orphan $γ$-ray flare fraction point toward leptonic processes as the likely mechanism for the high-energy emission. Motivated to discriminate between synchrotron self-Compton and external-Compton dominance in individual sources, we use the flux-flux variations to determine the slope $m$ of the ${\rm log}\,f_{\rm opt} - {\rm log}\,f_γ$ dependence. The slope distribution suggests a bimodal population with high and intermediate synchrotron-peak objects showing larger $m$ than low synchrotron-peak objects. We find that $m$ is naturally decreased through pollution from the orphan (typically optical) flares and develop a method to statistically recover, given the sources' measured orphan flare rate, the intrinsic $m$. While source classes show composite behavior, the majority of BL Lac objects favor $m=2$, indicating a synchrotron self-Compton origin for the $γ$-rays. No preference for either $m$ is found in flat spectrum radio quasars.

Chinese Import Competition and Media Slant in U.S. Local Newspapers
Creators: name: Wu, Linghui
Publisher: name: University of Chicago

Subjects: subject: international trade
subject: sentiment analysis

description: Does the recent surge in Chinese imports affect the media slant against China in the United States? Using a dataset of 157 U.S. local newspapers from 1998 to 2017, I construct a new measure of media bias through machine-learning-based sentiment analysis. Implementing the shift-share empirical strategy on the newspaper level, this paper finds that newspapers whose circulation states face greater exposure to Chinese import competitions report more negative news about China. The source of negative description more stems from non-trade-related topics and editorials. Though the findings in Lu et al. (2018) remain unchanged, this paper argues an overestimation tendency in the previous literature by matching keywords and tries to provide less unbiased point estimates.

description: We experimentally and theoretically challenge the concept of coherent perfect absorption (CPA) as a narrow frequency resonant mechanism associated with scattering processes that respect scale-invariance. Using a microwave platform, consisting of a lossy nonlinear resonator coupled to two interrogating antennas, we show that a coherent incident excitation can trigger a self-induced perfect absorption once its intensity exceeds a critical value. Importantly, a (near) perfect absorption persists for a broad band frequency range around the nonlinear CPA condition. Its origin is traced to a quartic behavior that the absorbance spectrum acquires in the proximity of a CPA associated with a new kind of exceptional point degeneracy related to the zeros of the nonlinear scattering operator.

description: We utilize the complimentary capabilities of XMM-Newton and Chandra, to conduct a detailed imaging and spectral study of the nearby galaxy NGC 4945 focussing on its nucleus and immediate surroundings (within ~1 kpc of the nucleus). A complex morphology is revealed including a predominantly hard, but partially resolved, nuclear source plus a spectrally soft, conically shaped X-ray "plume", which extends 30" (500 pc) to the northwest. In NGC 4945 our direct view of the active galactic nucleus (AGN) is blocked below ~10 keV by extremely heavy line-of-sight absorption and the observed X-ray spectrum is dominated by multi-temperature thermal emission associated with the nuclear starburst and the X-ray plume. Nevertheless the signature of the AGN is present in the form of a neutral Compton reflection component and a 6.4 keV fluorescent iron Ka line. We conjecture that the site of the continuum reprocessing is the far wall of a highly inclined molecular torus, a geometry which is consistent with the presence of H2O megamaser emission in this source. The soft spectrum (~0.6 keV) and limb-brightened appearance of the X-ray plume suggest an interpretation in terms of a mass-loaded superwind emanating from the nuclear starburst.

description: A discussion of torsion of Riemannian G-structures leads to a survey of contributions of Alfred Gray and others on almost Hermitian manifolds, G_2-manifolds, curvature identities, volume expansions, plotting geodesics, and the geometry of nilmanifolds. The paper concludes with a new example of a compact 8-manifold with a quaternionic 4-form that is closed but not parallel.

A Fully Polynomial Parameterized Algorithm for Counting the Number of Reachable Vertices in a Digraph

description: We consider the problem of counting the number of vertices reachable from each vertex in a digraph $G$, which is equal to computing all the out-degrees of the transitive closure of $G$. The current (theoretically) fastest algorithms run in quadratic time; however, Borassi has shown that this probl m is not solvable in truly subquadratic time unless the Strong Exponential Time Hypothesis fails [Inf. Process. Lett., 116(10):628--630, 2016]. In this paper, we present an $\mathcal{O}(f^3n)$-time exact algorithm, where $n$ is the number of vertices in $G$ and $f$ is the feedback edge number of $G$. Our algorithm thus runs in truly subquadratic time for digraphs of $f=\mathcal{O}(n^{\frac{1}{3}-ε})$ for any $ε> 0$, i.e., the number of edges is $n$ plus $\mathcal{O}(n^{\frac{1}{3}-ε})$, and is fully polynomial fixed parameter tractable, the notion of which was first introduced by Fomin, Lokshtanov, Pilipczuk, Saurabh, and Wrochna [ACM Trans. Algorithms, 14(3):34:1--34:45, 2018]. We also show that the same result holds for vertex-weighted digraphs, where the task is to compute the total weights of vertices reachable from each vertex.

description: We study the asymptotic of the spectrum of the \spin Dirac operator on high tensor powers of a line bundle. As application, we get a simple proof of the main result of Guillemin-Uribe, which was originally proved by using the analysis of Toeplitz operators of Boutet de Monvel and Guillemin.

description: We study RKKY interactions for magnetic impurities on graphene in situations where the electronic spectrum is in the form of Landau levels. Two such situations are considered: non-uniformly strained graphene, and graphene in a real magnetic field. RKKY interactions are enhanced by the lowest Landau level, which is shown to form electron states binding with the spin impurities and add a strong non-perturbative contribution to pairwise impurity spin interactions when their separation $R$ no more than the magnetic length. Beyond this interactions are found to fall off as $1/R^3$ due to perturbative effects of the negative energy Landau levels. Based on these results, we develop simple mean-field theories for both systems, taking into account the fact that typically the density of states in the lowest Landau level is much smaller than the density of spin impurities. For the strain field case, we find that the system is formally ferrimagnetic, but with very small net moment due to the relatively low density of impurities binding electrons. The transition temperature is nevertheless enhanced by them. For real fields, the system forms a canted antiferromagnet if the field is not so strong as to pin the impurity spins along the field. The possibility that the system in this latter case supports a Kosterlitz-Thouless transition is discussed.

description: A major challenge of CRISPR/Cas9-mediated genome engineering is that not all guide RNAs cleave DNA efficiently. Here, we show that local gRNA-DNA interactions resulting from Cas9 sliding on overlapping protospacer adjacent motifs profoundly impact gRNA activities. Using an energy model, we identify a sweet-spot range of binding energies for optimal efficiency which largely explains why favourable gRNAs can display changes in efficiency depending on the Cas9 binding context. Our results provide novel insights into the mechanisms of Cas9-PAM compatibility and cleavage activation and underline the importance of accounting for local sliding in gRNA design.

description: Notosolenus apocamptus Stokes, 1884
(fi gures 9b, 10c, d)
 Description. Cell outline oval or ovate, 7-12 Mm long (mostly 8-11 Mm), 4-7 Mm wide, about 2 Mm thick, fl attened. The anterior end is slightly narrowed, the posterior end is roundish. A deep longitudinal dorsal groove runs along the entire cell. Both sides of the groove are slightly rounded. Two fl agella of unequal length emerge from an ovate reservoir in the right-hand side of the cell. The anterior fl agellum is approximately 1.5-1.8 times the cell length and the posterior fl agellum is approximately 0.4-0.6 times the cell length. The nucleus is located on the left of the cell. Cells move by smooth gliding with anterior fl agellum extended. Common.
 Remarks. This species was fi rst described by Stokes (1884) from freshwater sites. Previously reported with lengths from 6.5 to 18 Mm (Stokes, 1884; Skuja, 1939; Larsen and Patterson, 1990; Ekebom et al., 1996; Patterson and Simpson, 1996). This species was described from marine sites in subtropical and tropical Australia, Brazil and Fiji (Larsen and Patterson, 1990; Ekebom et al., 1996; Patterson and Simpson, 1996). Generally, cells described here are consistent with those described by Larsen and Patterson (1990). This species is distinguished from others of the genus Notosolenus by its small size and deep dorsal groove. This species resembles Petalomonas minuta Hollande, 1942 in general appearance, but it is distinguished by the presence of a recurrent posterior fl agellum and a dorsal groove. Notosolenus apocamptus is similar to N. stenoschismus Skuja, 1939 in general cell shape and in having a groove, but N. stenoschismus is slightly larger, has indistinct pellicular striations and has a ventral groove. This species can be confused with N. similis because of similar general appearance and length range (see N. simili s, below).

description: Sco X-2 (GX 349+2) is a low-mass X-ray binary and Z source. We have analysed 156 ks of Rossi X-ray Timing Explorer data, obtained in 1998 January, on this source. We investigated the fast-time variability as a function of position on the Z track. During these observations, Sco X-2 traced out the most extensive Z track ever reported from this object, making this the most comprehensive study thus far. We found the broad peaked flaring branch noise that is typical of Sco X-2, with a centroid frequency in the range 3.3--5.8 Hz. We also discovered low frequency noise, and a new peaked noise feature, with centroid frequencies in the range 5.4--7.6 Hz and 11--54 Hz, respectively. We discuss the phenomenology of these features, their relationship with the power spectral components found in other low-mass X-ray binaries, and the implications for current models. In particular, the low frequency noise we observed was strongest at intermediate energies, in contrast to the low frequency noise seen in other Z sources. We also detected very low frequency noise, and have calculated complex cross spectra between intensity and hardness. We found that the very low frequency noise is not entirely due to motion along the Z track.

Resolving continua of fractional excitations by spinon echo in THz 2D coherent spectroscopy

description: We show that the new technique of terahertz 2D coherent spectroscopy is capable of giving qualitatively new information about fractionalized spin systems. For the prototypical example of the transverse field Ising chain, we demonstrate theoretically that, despite the broad continuum of excitations in linear response, the 2D spectrum contains sharp features that are a coherent signature of a `spinon echo', which gives previously inaccessible information such as the lifetime of the two-spinon excited state. The effects of disorder and finite lifetime, which are practically indistinguishable in the linear optical or neutron response, manifest in dramatically different fashion in the 2D spectra. Our results may be directly applicable to model quasi-1D transverse field Ising chain systems such as CoNb$_2$O$_6$, but the concept can be applied to fractionalized spin systems in general.

Mediated interaction between polarons in a one-dimensional Bose gas

description: We study a weakly-interacting one-dimensional Bose gas with two impurities coupled locally to the boson density. We derive analytical results for the induced interaction between the impurities at arbitrary coupling and separation $r$. At $r\lesssim ξ$, where $ξ$ denotes the healing length of the Bose gas, the interaction is well described by the mean-field contribution. Its form changes as the coupling is increased, approaching a linear function of $r$ at short distances in the regime of strong coupling. The mean-field contribution decays exponentially at arbitrary coupling for $r\ggξ$. At such long distances, however, the effect of quantum fluctuations becomes important, giving rise to a long-ranged quantum contribution to the induced interaction. At longest distances it behaves as $1/r^3$, while at strong coupling we find an intermediate distance regime with a slower decay, $1/r$. The quantum contribution in the crossover regime is also calculated. The induced interaction between impurities (i.e., polarons) is attractive and leads to the formation of their bound state, known as bipolaron. We discuss its binding energy.

Ethics in real and virtual medical world - an event report

description: Background: Nature and its universal laws create ethics, life and survival in the real world. The situation in the virtual world might be different. Aims: To describe an event of ethics in the real world of an open access journal and to analyze its components and influence in the neighboring virtual community. Event: A scientific article was submitted for publication to the open access journal (OAJ) www.diagnosticpathology.eu It was accepted after thorough review and language corrections and published after a short time. The authors withdraw the article a few days after publication and claimed that the experimental data were incorrect. A few days later an identical article was submitted to the OAJ www.diagnosticpathology.org for publication and displayed ‘under review’. Interpretation: OAJs might be considered the entrance to a new environment called virtual universe. They do no longer belong to the physical ‘real’ nature because they ‘live’ in an electronic network which provides an environment might different from the real nature. Examples are reversibility of time, two dimensional structures only as well as different sources of energy and information transfer. Consecutives: Ethics and associated behavior of ‘living’ elements (events) in a virtual universe should not be judged by conventional parameters of the ‘real world’. They require their own regulations and interpretation.
