Authors: Xu Wenbin , Xia Hong , Liu Wei , Zheng Weiying , Hua Lin 
Published: May 2018

BACKGROUND AND OBJECTIVE: Muscle-invasive bladder cancers (MIBCs) are heterogeneous cancers and can be grouped into basal-like and luminal subtypes that are highly reminiscent of those found in breast cancer. Like basal-like breast cancers, basal-like MIBCs are associated with advanced stage and metastatic disease. However, the biological and clinical significance of molecular subtypes of MIBCs remain unclear. Therefore, we implemented a serious of bioinformatics methods to explore genetic similarities between bladder and breast cancers. METHODS AND RESULTS: In the current study, by the application of multiple levels data analysis including random forest analysis, PPI and transcription factor regulation network construction, Gene Ontology (GO) and KEGG pathway enrichment analysis, we explored the genetics commonness between MIBC and breast cancers from the molecular heterogeneity based on the disease subtypes. CONCLUSIONS: Our study identified some basal-related and luminal-related genes shared by two cancers. These studies can help shed light on the potential relationships between MIBC and breast cancer as a whole.

BACKGROUND: Magnesium ion, as important cation in the human body, involved in various enzymatic reactions, glucose transport and insulin release. Now diabetes mellitus and diabetic complications have become important public health problems around the world. OBJECTIVE: This paper explores the association between concentration levels of serum magnesium and common complications and comorbidities of diabetes mellitus and other biochemical indexes. METHODS: There are 1217 eligible patients selected from 14,317 cases of diabetic hospitalization patients from January 2010 to December 2011. Random forest algorithm was applied to assess the importance of various biochemical indexes and to perform diabetic complications prediction. RESULTS: The research results showed that low concentration of serum magnesium and four common diabetic complications – diabetic retinopathy, diabetic nephropathy, diabetic neuropathy and diabetic macroangiopathy – exists association, but no obvious correlation with other comorbidities like hypertension. CONCLUSIONS: The specific factors of four common diabetic complications were selected from the biochemical indexes to provide a reference direction for further research.

BACKGROUND: Dancesport is a popular activity among older adults who look for fun and fitness in Korea. Studies reported positive sociological and psychological effects of dancesport. But, little studies were performed to evaluate the effects of dancesport on balance performances. OBJECTIVE: The objective of the present study was to evaluate the effects of dancesport for 15 weeks on walking balance and standing balance of older adults. METHODS: Older adults regularly participated in the dancesport program 3 times a week for 15 weeks. The program included Rumba, Cha-cha-cha, and Jive. They exercised the prescribed dancesport at intermediate level for 50–60 mins for each time. A total 22 reflective markers were placed on the anatomical landmarks and 8 cameras were used to measure 3-D positions of participants. Also, center of pressure (COP) data were measured to analyze standing balance using a ground reaction board at 1200 Hz for 30 seconds. One-way analysis of variance (ANOVA) was performed to test the effects of 15 weeks of dancesport on walking balance and standing balance. RESULTS: The results suggested that, after 15 weeks of dancesport participation, older adults’ walking balance (48.3 [Formula: see text] 20.3 cm[Formula: see text] vs 38.2 [Formula: see text] 18.2 cm[Formula: see text]) and standing balance (COP area: 189.4 [Formula: see text] 85.4 mm[Formula: see text] vs 103.5 [Formula: see text] 55.4mm[Formula: see text], COP distance: 84.2 [Formula: see text] 34.4 cm vs 76.5 [Formula: see text] 21.4 cm) were significantly improved. CONCLUSION: Performing dancesport would require moving center of mass rapidly and frequently while maintaining posture. This may result in improving walking balance and standing balance in the present study. The study concluded that dancesport would be an effective exercise method in enhancing postural stability of older adults.

Authors: Li Mi , Xu Hongpei , Liu Xingwang , Lu Shengfu 
Published: May 2018

BACKGROUND: Many studies have been done on the emotion recognition based on multi-channel electroencephalogram (EEG) signals. OBJECTIVE: This paper explores the influence of the emotion recognition accuracy of EEG signals in different frequency bands and different number of channels. METHODS: We classified the emotional states in the valence and arousal dimensions using different combinations of EEG channels. Firstly, DEAP default preprocessed data were normalized. Next, EEG signals were divided into four frequency bands using discrete wavelet transform, and entropy and energy were calculated as features of K-nearest neighbor Classifier. RESULTS: The classification accuracies of the 10, 14, 18 and 32 EEG channels based on the Gamma frequency band were 89.54%, 92.28%, 93.72% and 95.70% in the valence dimension and 89.81%, 92.24%, 93.69% and 95.69% in the arousal dimension. As the number of channels increases, the classification accuracy of emotional states also increases, the classification accuracy of the gamma frequency band is greater than that of the beta frequency band followed by the alpha and theta frequency bands. CONCLUSIONS: This paper provided better frequency bands and channels reference for emotion recognition based on EEG.
Scrounging and Salvaging: Literary Guidance and the Descent into the Underworld in the Inferno, Paradise Lost, Frankenstein and Heart of Darkness
Authors: Agarwal Megha 
Published: May 2018

Socrates, in Phaedo, posits that the route to Hades is far from ‘straightforward’, and that it is riddled with ‘crossroads’ that demand the presence of a vigilant guide. The possibility of multiple routes culminating in the underworld, and the necessity of guidance, form the bedrock of the interwoven analysis of the Inferno, Paradise Lost, Frankenstein, and Heart of Darkness. Amidst the profusion of pathways, the Inferno and Paradise Lost gesture towards a direction that is replicated and repudiated in Mary Shelley and Joseph Conrad's versions of the descent voyage in Frankenstein and Heart of Darkness. Dante and Milton's ‘prototype’ narratives exemplify the descent – or the fall – into hell, and shape the two novels through ‘literary guidance’. Heart of Darkness emerges as an inversion of the meticulously structured Dantean universe. The Pilgrim's progress in the Inferno is a consistent counterpoint to Conradian chaos and Marlow's wilful yet meandering descent into colonial Africa. Dante's Pilgrim emerges from the underworld to progress onwards, while Marlow remains entrenched in the inescapably infernal condition of twentieth-century imperialism. The Inferno is an unacknowledged spectre that haunts the proceedings of the novella, but Milton's poetic re-telling of Genesis is a recognised presence in Frankenstein. Paradise Lost is re-viewed through the perspective of the hapless Monster, who oscillates between identifying with Satan and Adam. Both poets thus dabble in the attainment (or the elusiveness) of salvation, while the novelists struggle to salvage a semblance of significance with which they can imbue their characters' journeys. While 2016 saw several literary anniversaries, a strand that the organisers envisioned intertwining with ‘salvaging’, the year 2015 marked the 750th birth anniversary of Dante, sparking speculation about the present-day pertinence of the afterlife. This interplay between the theme of Salvage and these four narratives ought to provide unexpected insights that complement BCLA's emphasis on renewing critical perspectives.
Indefeasible Family Rights: A Comparative View on the Restrictions of Testamentary Freedom
Authors: Roggendorf Hannah 
Published: May 2018

Testamentary freedom and family protection in succession law are often described as contradictory principles. Nonetheless, in most European legal systems both principles coexist. This article focuses on three conceptions of this coexistence: legal rights in Scotland, compulsory portion in Germany and family provision in England. All three systems must accommodate changing values of family life in modern society. Most recently, the timeliness of traditional solutions has been a controversial topic of the debate leading to the Succession (Scotland) Act 2016, and it continues to be an issue of debate, because regarding legal rights no final solution has been found. A comparative analysis can demonstrate the interconnectedness between social values and legal concepts, and it can further identify potential for legal innovation. Family rights, especially in Germany, have been contextualised with a historic notion of family property. In the present law of all three countries the contextual emphasis shifts towards familial solidarity and a moral duty to provide for family members. On a concrete level, there is a discernible connection between matrimonial property relationships and spousal rights to the estate in Germany and England, which in Scotland is no longer present. Further, the English system can also accommodate cohabitants as potential claimants. Scots law has at least in the case of intestacy incorporated a similar provision, while German law thus far does not provide any legal concept for cohabitation.
Toward the ICRF3: Astrometric Comparison of the USNO 2016A VLBI Solution with ICRF2 and Gaia DR1

Published: May 2018

Abstract
The VLBI USNO 2016A (U16A) solution is part of a work-in-progress effort by USNO toward the preparation of the ICRF3. Most of the astrometric improvement with respect to the ICRF2 is due to the re-observation of the VCS sources. Our objective in this paper is to assess U16A’s astrometry. A comparison with ICRF2 shows statistically significant offsets of size 0.1 mas between the two solutions. While Gaia DR1 positions are not precise enough to resolve these offsets, they are found to be significantly closer to U16A than ICRF2. In particular, the trend for typically larger errors for southern sources in VLBI solutions is decreased in U16A. Overall, the VLBI-Gaia offsets are reduced by 21%. The U16A list includes 718 sources not previously included in ICRF2. Twenty of those new sources have statistically significant radio-optical offsets. In two-thirds of the cases, these offsets can be explained from PanSTARRS images.

Abstract
We present Submillimeter Array and Northern Extended Millimeter Array observations of the host galaxy of FRB 121102 in the CO 3–2 and 1–0 transitions, respectively. We do not detect emission from either transition. We set 3σ upper limits to the CO luminosity L
CO < 2.5 × 107 K km s−1 pc−2 for CO 3–2 and L
CO < 2.3 × 109 K km s−1 pc−2 for CO 1–0. For Milky Way–like star formation properties, we set a 3σ upper limit on the H2 mass of 2.5 × 108
M
⊙, slightly less than the predictions for the H2 mass based on the star formation rate. The true constraint on the H2 mass may be significantly higher, however, because of the reduction in CO luminosity that is common for low-metallicity dwarf galaxies like the FRB host galaxy. These results demonstrate the challenge of identifying the nature of FRB progenitors through study of the host galaxy molecular gas. We also place a limit of 42 μJy (3σ) on the continuum flux density of the persistent radio source at 97 GHz, consistent with a power-law extrapolation of the low-frequency spectrum, which may arise from an active galactic nucleus or other nonthermal source.
A Comprehensive K2 and Ground-based Study of CRTS J035905.9+175034, an Eclipsing SU UMa System with a Large Mass Ratio
Authors: Littlefield Colin , Garnavich Peter , Kennedy Mark , Szkody Paula , Dai Zhibin 
Published: May 2018

Abstract
CRTS J035905.9+175034 is the first eclipsing SU UMa system for which a superoutburst has been observed by Kepler in the short-cadence mode. The light curve contains one superoutburst, eight normal outbursts (including a precursor to the superoutburst), and several minioutbursts that are present before—but not after—the superoutburst. The superoutburst began with a precursor normal outburst, and shortly after the peak of the precursor, the system developed large-amplitude superhumps that achieved their maximum amplitude after just three superhump cycles. The period excess of the initial superhump period relative to the orbital period implies a mass ratio of 0.281 ± 0.015, placing it marginally above most theoretical predictions of the highest-possible mass ratio for superhump formation. In addition, our analysis of the variations in eclipse width and depth, as well as the hot spot amplitudes, generally provides substantiation of the thermal-tidal instability model. The K2 data, in conjunction with our ground-based time-resolved spectroscopy and photometry from 2014 to 2016, allows us to determine many of the fundamental parameters of this system.

Abstract
Proxima Centauri has become the subject of intense study since the radial-velocity (RV) discovery by Anglada-Escudé et al. of a planet orbiting this nearby M dwarf every ∼11.2 days. If Proxima Centauri b transits its host star, independent confirmation of its existence is possible, and its mass and radius can be measured in units of the stellar host mass and radius. To date, there have been three independent claims of possible transit-like event detections in light curve observations obtained by the MOST satellite (in 2014–15), the Bright Star Survey Telescope telescope in Antarctica (in 2016), and the Las Campanas Observatory (in 2016). The claimed possible detections are tentative, due in part to the variability intrinsic to the host star, and in the case of the ground-based observations, also due to the limited duration of the light curve observations. Here, we present preliminary results from an extensive photometric monitoring campaign of Proxima Centauri, using telescopes around the globe and spanning from 2006 to 2017, comprising a total of 329 observations. Considering our data that coincide directly and/or phased with the previously published tentative transit detections, we are unable to independently verify those claims. We do, however, verify the previously reported ubiquitous and complex variability of the host star. We discuss possible interpretations of the data in light of the previous claims, and we discuss future analyses of these data that could more definitively verify or refute the presence of transits associated with the RV-discovered planet.
The Nucleus of Active Asteroid 311P/(2013 P5) PANSTARRS

Published: May 2018

Abstract
The unique inner-belt asteroid 311P/PANSTARRS (formerly P/2013 P5) is notable for its sporadic, comet-like ejection of dust in nine distinct epochs spread over ∼250 days in 2013. This curious behavior has been interpreted as the product of localized, equatorward landsliding from the surface of an asteroid rotating at the brink of instability. We obtained new Hubble Space Telescope observations to directly measure the nucleus and to search for evidence of its rapid rotation. We find a nucleus with mid-light absolute magnitude H

V
= 19.14 ± 0.02, corresponding to an equal-area circle with radius 190 ± 30 m (assuming geometric albedo p

V
= 0.29). However, instead of providing photometric evidence for rapid nucleus rotation, our data set a lower limit to the light-curve period, P ≥ 5.4 hr. The dominant feature of the light curve is a V-shaped minimum, ∼0.3 mag deep, which is suggestive of an eclipsing binary. Under this interpretation, the time-series data are consistent with a secondary/primary mass ratio, m

s
/m

p
∼ 1:6, a ratio of separation/primary radius, r/r

p
∼ 4 and an orbit period ∼0.8 days. These properties lie within the range of other asteroid binaries that are thought to be formed by rotational breakup. While the light-curve period is long, centripetal dust ejection is still possible if one or both components rotate rapidly (≲2 hr) and have small light-curve variation because of azimuthal symmetry. Indeed, radar observations of asteroids in critical rotation reveal “muffin-shaped” morphologies, which are closely azimuthally symmetric and which show minimal light curves. Our data are consistent with 311P being a close binary in which one or both components rotates near the centripetal limit. The mass loss in 2013 suggests that breakup occurred recently and could even be on-going. A search for fragments that might have been recently ejected beyond the Hill sphere reveals none larger than effective radius r

Effective Induction Heating around Strongly Magnetized Stars

Published: May 2018

Abstract
Planets that are embedded in the changing magnetic fields of their host stars can experience significant induction heating in their interiors caused by the planet’s orbital motion. For induction heating to be substantial, the planetary orbit has to be inclined with respect to the stellar rotation and dipole axes. Using WX UMa, for which the rotation and magnetic axes are aligned, as an example, we show that for close-in planets on inclined orbits, induction heating can be stronger than the tidal heating occurring inside Jupiter’s satellite Io; namely, it can generate a surface heat flux exceeding 2 W m−2. An internal heating source of such magnitude can lead to extreme volcanic activity on the planet’s surface, possibly also to internal local magma oceans, and to the formation of a plasma torus around the star aligned with the planetary orbit. A strongly volcanically active planet would eject into space mostly SO2, which would then dissociate into oxygen and sulphur atoms. Young planets would also eject CO2. Oxygen would therefore be the major component of the torus. If the O i column density of the torus exceeds ≈1012 cm−2, the torus could be revealed by detecting absorption signatures at the position of the strong far-ultraviolet O i triplet at about 1304 Å. We estimate that this condition is satisfied if the O i atoms in the torus escape the system at a velocity smaller than 1–10 km s−1. These estimates are valid also for a tidally heated planet.
An Empirical Fitting Method to Type Ia Supernova Light Curves. III. A Three-parameter Relationship: Peak Magnitude, Rise Time, and Photospheric Velocity
Authors: Zheng WeiKang , Kelly Patrick L. , Filippenko Alexei V. 
Published: May 2018

Abstract
We examine the relationship between three parameters of Type Ia supernovae (SNe Ia): peak magnitude, rise time, and photospheric velocity at the time of peak brightness. The peak magnitude is corrected for extinction using an estimate determined from MLCS2k2 fitting. The rise time is measured from the well-observed B-band light curve with the first detection at least 1 mag fainter than the peak magnitude, and the photospheric velocity is measured from the strong absorption feature of Si ii λ6355 at the time of peak brightness. We model the relationship among these three parameters using an expanding fireball with two assumptions: (a) the optical emission is approximately that of a blackbody, and (b) the photospheric temperatures of all SNe Ia are the same at the time of peak brightness. We compare the precision of the distance residuals inferred using this physically motivated model against those from the empirical Phillips relation and the MLCS2k2 method for 47 low-redshift SNe Ia (0.005 < z < 0.04) and find comparable scatter. However, SNe Ia in our sample with higher velocities are inferred to be intrinsically fainter. Eliminating the high-velocity SNe and applying a more stringent extinction cut to obtain a “low-v golden sample” of 22 SNe, we obtain significantly reduced scatter of 0.108 ± 0.018 mag in the new relation, better than those of the Phillips relation and the MLCS2k2 method. For 250 km s−1 of residual peculiar motions, we find 68% and 95% upper limits on the intrinsic scatter of 0.07 and 0.10 mag, respectively.
Fossil Merger of a Population II Star

Published: May 2018

Abstract
We report on a fossil stellar merger for the subgiant primary of the visual binary HR 3750. The subgiant leads to an age τ ≃ 3.2 Gyr for a mass M
A = 1.39 ± 0.09 M
⊙, in contradiction with its low iron-to-magnesium abundance that classifies it as a Population II (thick-disk) star. Upon the assumption of an ancient source, and since there appears to be no inner Aa–Ab subsystem for HR 3750, the mass of the subgiant primary can only be understood in terms of a merger with a former tertiary component. In a mass conserving scenario, and with M
Aa = 1.03 ± 0.03 M
⊙ as the likely progenitor mass of the primary, the mass of the accreted companion is suggestive of an M dwarf at M
Ab = 0.36 ± 0.03 M

The Diffuse Radiation Field at High Galactic Latitudes

Published: May 2018

Abstract
We have used GALEX observations of the north and south Galactic poles to study the diffuse ultraviolet background at locations where the Galactic light is expected to be at a minimum. We find offsets of 230–290 photon units in the far-UV (1531 Å) and 480–580 photon units in the near-UV (2361 Å). Of this, approximately 120 photon units can be ascribed to dust-scattered light and another 110 photon units (190 in the near-UV) to extragalactic radiation. The remaining radiation is, as yet, unidentified and amounts to 120–180 photon units in the far-UV and 300–400 photon units in the near-UV. We find that molecular hydrogen fluorescence contributes to the far-UV when the 100 μm surface brightness is greater than 1.08 MJy sr−1.
