Tradition and Modernity in Scruton's Aesthetics
Authors: Hughes Samuel 
Published: July 2019

AbstractDuring the last century, most Western artists abandoned the traditional forms of Western art. Two closely related questions arise at once: why did artists do this, and were they right to? Scruton is famous for arguing that the answer to the latter question is no. His response to the former question is, by contrast, little known. In this paper, I investigate Scruton's discussions of it, arguing that a more complex and equivocal picture of the relationship between tradition and modernity quickly emerges. Scruton actually gives two mutually inconsistent genealogies of the flight from tradition. The first, surprisingly, is inconsistent with Scruton's defence of traditional forms, as well as with a number of his other commitments. The second coheres better with his other commitments, and on one version is consistent with his traditionalism. To vindicate his traditionalism this way, however, Scruton would be constrained to make an interesting and significant commitment.
Reactionary Internationalism: the philosophy of the New Right
Authors: de Orellana Pablo , Michelsen Nicholas 
Published: July 2019

AbstractWhat does the New Right want from international relations? In this article, we argue that the philosophy of the New Right is not reducible to a negation of internationalism. The New Right coalesce around a conceptualisation of the international driven by analytics and critiques of specific subjects, norms and practices, that should be treated as a distinct international theoretical offering. We refer to this vision as Reactionary Internationalism. This article examines and locates this vision within the intellectual history of nationalism and internationalism by drawing on poststructuralist approaches to intellectual history and drawing evidence from a discourse analysis of recent Lega, Front National, Brexit, and Trump campaigns. We find that, rather than advocating for the end of internationalism, the New Right seeks to reconstitute its normative architecture on the basis of inequality among identities. This entails dismantling liberal economic and rights-based norms and reframing them around transactionalism and power grounded on identity. Reactionary Internationalism emerges as a distinct philosophy that identifies a hegemonic normative bind and advocates its unravelling so as to liberate subjects understood as defined by their birth-cultural identity.
ON VARIABILITY OF SERIES AND PARALLEL SYSTEMS WITH HETEROGENEOUS COMPONENTS
Authors: Zhang Yiying , Ding Weiyong , Zhao Peng 
Published: July 2019

AbstractThis paper studies the variability of both series and parallel systems comprised of heterogeneous (and dependent) components. Sufficient conditions are established for the star and dispersive orderings between the lifetimes of parallel [series] systems consisting of dependent components having multiple-outlier proportional hazard rates and Archimedean [Archimedean survival] copulas. We also prove that, without any restriction on the scale parameters, the lifetime of a parallel or series system with independent heterogeneous scaled components is larger than that with independent homogeneous scaled components in the sense of the convex transform order. These results generalize some corresponding ones in the literature to the case of dependent scenarios or general settings of components lifetime distributions.
Germination characteristics and the relationship between population structure, soil seed bank density and fire response in the rare endemic Stachystemon vinosus (Halford & R.J.F.Hend.) (Euphorbiaceae) from southern Western Australia

AbstractThe regeneration niche defines the specific environmental requirements of the early phases of a plant's life cycle. It is critical for the long-term persistence of plant populations, particularly for obligate seeders that are highly vulnerable to stochastic events in fire-prone ecosystems. Here, we assessed germination characteristics and the relationship between population structure, soil seed bank density and fire response in Stachystemon vinosus (Euphorbiaceae), a rare endemic shrub from Western Australia, from burnt and long unburnt habitats. Many plants in long unburnt habitat were similar in size to those in recently burnt habitat. Soil seed bank density was related to plant abundance and fire history with density lower in burnt than unburnt sites. Thus, inter-fire recruitment may play a critical role in the requirements of the study species. To assess the dormancy status and germination requirements we used a ‘move-along’ experiment with temperatures from six seasonal phases of the year. Seeds were incubated under light and dark conditions, with and without smoked water, and with and without dry after-ripening. Germination was most effective when seeds were treated with smoked water and incubated in the dark at temperatures resembling autumn/winter conditions. After-ripening increased germination in light and dark incubated seeds in the absence of smoked water but was unnecessary for optimal germination in smoked water treated seeds. Irrespective of treatment, seeds showed a requirement for cooler temperatures for germination. These results suggest that rising temperatures and changes in fire regime associated with global warming may alter future germination responses of Stachystemon vinosus.
Depressive Symptoms and Blood Pressure
Authors: Montano Diego 
Published: July 2019

Abstract. In the present investigation it is hypothesized that depressive symptoms and antidepressant therapy are associated with systolic and diastolic blood pressure. Moreover, in additional analyses, the interaction effects of age, gender, and depressive symptoms are estimated, and discussed in the context of previous findings. Data from the German Health Interview and Examination Survey for Adults (DEGS1) were analyzed ( N = 7,987) by means of multi-response Bayesian hierarchical regression models. Missing data were imputed by the method of chain equations. Independent variables included depressive symptoms, antidepressant medication, gender, age, smoking, physical activity, family history of hypertension, body mass index, and antihypertensive medication. The estimates obtained in the multi-response model revealed that depressive symptoms were negatively associated with arterial blood pressure (−0.09, 99% CI [−0.147; −0.040]). Antidepressant therapy was found to be positively associated with increased blood pressure (1.035, 99% CI [0.333; 1.990]). There were negative interaction effects of depressive symptoms and age among women only (−0.006 99% CI [−0.010; −0.001]). The results agree with previous findings reporting a negative association between depressive symptoms and blood pressure. In addition, regarding the trajectory of blood pressure across the lifespan, interaction effects of depressive symptoms and age were found among females. The results indicate a linear increase in blood pressure with increasing age which, however, tends to flatten and decrease by around age 55 in both males and females. Potential physiological mechanisms may be related to affect regulation taking place at higher levels of cognitive processing and affecting blood pressure regulation, and/or cardiovascular mechanisms related to cerebral blood flow, arterial blood pressure, and depressive symptoms which have not been sufficiently explained so far.
Global Estimates of the Energy Transfer From the Wind to the Ocean, With Emphasis on Near‐Inertial Oscillations

Published: July 2019

AbstractEstimates of the kinetic energy transfer from the wind to the ocean are often limited by the spatial and temporal resolution of surface currents and surface winds. Here we examine the wind work in a pair of global, very high‐resolution (1/48° and 1/24°) MIT general circulation model simulations in Latitude‐Longitude‐polar Cap (LLC) configuration that provide hourly output at spatial resolutions of a few kilometers and include tidal forcing. A cospectrum analysis of wind stress and ocean surface currents shows positive contribution at large scales (>300 km) and near‐inertial frequency and negative contribution from mesoscales, tidal frequencies, and internal gravity waves. Larger surface kinetic energy fluxes are in the Kuroshio in winter at large scales (40 mW/m2) and mesoscales (−30 mW/m2). The Kerguelen region is dominated by large scale (∼20 mW/m2), followed by inertial oscillations in summer (13 mW/m2) and mesoscale in winter (−12 mW/m2). Kinetic energy fluxes from internal gravity waves (−0.1 to −9.9 mW/m2) are generally stronger in summer. Surface kinetic energy fluxes in the LLC simulations are 4.71 TW, which is 25–85% higher than previous global estimates from coarser (1/6–1/10°) general ocean circulation models; this is likely due to improved representation of wind variability (6‐hourly, 0.14°, operational European Center for Medium‐Range Weather Forecasts). However, the low wind power input to the near‐inertial frequency band obtained with LLC (0.16 TW) compared to global slab models suggests that wind variability on time scales less than 6 hr and spatial scales less than 15 km are critical to better representing the wind power input in ocean circulation models.
Identification of a novel EphB4 phosphodegron regulated by the autocrine IGFII/IRA axis in malignant mesothelioma

Published: July 2019

AbstractMalignant mesothelioma is a deadly disease with limited therapeutic options. EphB4 is an oncogenic tyrosine kinase receptor expressed in malignant mesothelioma as well as in a variety of cancers. It is involved in tumor microenvironment mediating angiogenesis and invasive cellular effects via both EphrinB2 ligand-dependent and independent mechanisms. The molecular network underlying EphB4 oncogenic effects is still unclear. Here we show that EphB4 expression in malignant mesothelioma cells is markedly decreased upon neutralization of cancer-secreted IGF-II. In particular, we demonstrate that EphB4 protein expression in malignant mesothelioma cells depend upon a degradation rescue mechanism controlled by the autocrine IGF-II-insulin receptor-A specific signaling axis. We show that the regulation of EphB4 expression is linked to a competing post-translational modification of its carboxy-terminal tail via phosphorylation of its tyrosine 987 by the Insulin receptor isoform-A kinase-associated activity in response to the autocrine IGF-II stimuli. Neutralization of this autocrine-induced EphB4-phosphorylation by IGF-II associates with the increased ubiquitination of EphB4 carboxy-terminal tail and with its rapid degradation. We also describe a novel Ubiquitin binding motif in the targeted region as part of the identified EphB4 phosphodegron and provide 3D modeling data supporting a possible model for the acute EphB4 PTM-driven regulation by IGF-II. Altogether, these findings disclose a novel molecular mechanism for the maintenance of EphB4-expression in malignant mesothelioma cells and other IGF-II-secreting cancers (IGF2omas).
Local dynamics within the glass transition domain
Authors: Godey François , Fleury Alexandre , Soldera Armand 
Published: July 2019

AbstractThe glass transition of an amorphous material is a fundamental property characterized by an abrupt change in viscosity. Its very knowledge was a conundrum as no satisfying theory existed at the molecular level. We herein relate this complex phenomenon to events occurring at the molecular scale. By studying conformational transitions in the carbon-chain polymer of polyethylene, we clearly establish a relation between local dynamics and the classical dihedral potential energy diagram of a carbon-carbon bond. This methodology is applied to a carbon-chain polymer with a side-group, polystyrene. A direct link is proved between activation energy and glass transition temperature. This work thus provides the cornerstone for linking molecular structure to macroscopic polymer properties, and in particular, the glass transition temperature.
Effect of inter-layer spin diffusion on skyrmion motion in magnetic multilayers
Authors: Lepadatu Serban 
Published: July 2019

AbstractIt is well known that skyrmions can be driven using spin-orbit torques due to the spin-Hall effect. Here we show an additional contribution in multilayered stacks arises from vertical spin currents due to inter-layer diffusion of a spin accumulation generated at a skyrmion. This additional interfacial spin torque is similar in form to the in-plane spin transfer torque, but is significantly enhanced in ultra-thin films and acts in the opposite direction to the electron flow. The combination of this diffusive spin torque and the spin-orbit torque results in skyrmion motion which helps to explain the observation of small skyrmion Hall angles even with moderate magnetisation damping values. Further, the effect of material imperfections on threshold currents and skyrmion Hall angle is also investigated. Topographical surface roughness, as small as a single monolayer variation, is shown to be an important contributing factor in ultra-thin films, resulting in good agreement with experimental observations.

Published: July 2019

AbstractThis study investigated the incidence of transient hypothyroxinaemia of prematurity (THOP) associated with survival without composite morbidities and the predictability of THOP severity in extremely low birth weight infants (ELBWIs). We retrospectively reviewed the medical records of 546 ELBWIs who underwent initial thyroid function tests within 14 postnatal days, with 156 ELBWIs from 2000 to 2005 (period I) and 390 from 2006 to 2013 (period II). The infants were stratified into 23–24, 25–26 and 27–28 weeks’ gestation subgroups within each period; the initial thyroxine (T4) level, mortality, clinical characteristics and composite morbidities, including bronchopulmonary dysplasia, intraventricular haemorrhage, necrotizing enterocolitis, and retinopathy of prematurity were analysed. The predictive value of the initial T4 level, Apgar score at 5 min, and clinical risk index for babies II (CRIB II) score for estimating mortality and survival with or without composite morbidities was assessed. Comparing period II and period I, the incidence of THOP was significantly decreased along with significantly increased survival without composite morbidities in ELBWIs at 25–28 weeks’ gestation. The severity of THOP showed significant associations with mortality and composite morbidities. The initial T4 level was most effective for predicting outcome compared with Apgar and CRIB II scores.

AbstractThe species of the genusNannochloropsisare unique in their maintenance of a nucleus-plastid continuum throughout their cell cycle, non-motility and asexual reproduction. These characteristics should have been endorsed in their gene assemblages (genomes). Here we show thatN. oceanicahas a genome of 29.3 Mb consisting of 32 pseudochromosomes and containing 7,330 protein-coding genes; and the host nucleus may have been overthrown by an ancient red alga symbiont nucleus during speciation through secondary endosymbiosis. In addition,N. oceanicahas lost its flagella and abilities to undergo meiosis and sexual reproduction, and adopted a genome reduction strategy during speciation. We propose thatN. oceanicaemerged through the active fusion of a host protist and a photosynthesizing ancient red alga and the symbiont nucleus became dominant over the host nucleus while the chloroplast was wrapped by two layers of endoplasmic reticulum. Our findings evidenced an alternative speciation pathway of eukaryotes.
Optimal methodology for explicit solvation prediction of band edges of transition metal oxide photocatalysts
Authors: Park Kyoung-Won , Kolpak Alexie M. 
Published: July 2019

AbstractThe conduction and valence band edges (ECandEV) of a material relative to the water redox potential levels are critical factors governing photocatalytic water splitting activity. Here we discuss the large discrepancy in the experimentally measuredECandEVof various transition metal oxides (TMOs) in vacuum and in an aqueous solution. We speculate that the discrepancy stems from the different degree of electron transfer across the surface due to the different environment at the surface of the TMOs in vacuum and water. Accurately modeling the electronic structure at TMO/water interfaces is a significant challenge, however. Using first-principles density functional theory calculations on rutile titanium dioxide and cobalt monoxide model systems, here we identify the optimal approaches to accurately predict the band edge positions in vacuum and water. We then validate the optimized schemes on other TMOs, demonstrating good agreement with experimental measurements in both vacuum and water.

Published: July 2019

AbstractSupermolecules such as rotaxanes and catenanes have recently attracted considerable attention due to their potential widespread applications in areas such as molecular machines and switches. Moreover, the development of polyrotaxanes and polycatenanes, comprising multiple cyclic compounds, has allowed the fabrication of structures with novel properties. Although rotaxanes and polyrotaxanes have been extensively prepared from cyclodextrins as building blocks, very few studies have considered the syntheses of cyclodextrin-based polycatenanes. Here we report the one-pot syntheses and isolation of cyclodextrin-based radial polycatenanes with large numbers of cyclic components (>10) attached to a poly(ethylene glycol)–poly(propylene glycol)–poly(ethylene glycol) copolymer core, with characterization performed using Raman spectroscopy, gel permeation chromatography, 1H-NMR spectroscopy, and other techniques. Overall, the results presented herein may be used to develop advanced supramolecular structures and materials, such as molecular machines, molecular actuators, molecular switches, biomaterials, and drug carriers.

Published: July 2019

AbstractThe superconducting proximity effect has recently attracted a renewed interest as the basis of topologically nontrivial states in materials with a large spin–orbit interaction, with protected boundary states useful for quantum information technologies. However, spectroscopy of these states is challenging because of the limited control of conventional tunnel barriers. Here we report electronic spectroscopy measurements of the proximity gap in a semiconducting indium arsenide nanowire segment coupled to a superconductor, using quantum dots formed deterministically during the crystal growth. We extract characteristic parameters describing the proximity gap, which is suppressed for lower electron densities and fully developed for larger ones. This gate-tunable transition of the proximity effect can be understood as a transition from the long to the short junction regime of subgap bound states in the NW segment. Our device architecture opens up the way to systematic, quantitative spectroscopy studies of subgap states, such as Majorana-bound states.
Nuclear-spin dependent parity violation in optically trapped polyatomic molecules

Published: July 2019

AbstractImproved nuclear spin-dependent parity violation measurements will enable experimental determination of poorly known electroweak coupling parameters. Here, we investigate the suitability of optically trapped linear polyatomic molecules as probes of nuclear spin-dependent parity violation. The presence of closely spaced, opposite-parity $$\ell$$
ℓ
-doublets is a general feature of such molecules, allowing parity-violation-sensitive pairs of levels to be brought to degeneracy in magnetic fields typically 100 times smaller than in diatomics. Assuming laser cooling and trapping of polyatomics at the current state-of-the-art for diatomics, we expect to measure nuclear spin-dependent parity-violating matrix elements iW with 70 times better sensitivity than the current best measurements. Our scheme should allow for 10% measurements of iW in nuclei as light as Be or as heavy as Yb, with averaging times on the order of 10 days and 1 s, respectively.

Published: July 2019

Context. Although there have been numerous studies of chemical abundances in the Galactic bulge, the central two degrees have been relatively unexplored due to the heavy and variable interstellar extinction, extreme stellar crowding, and the presence of complex foreground disk stellar populations.
Aims. In this paper we discuss the metallicity distribution function, vertical and radial gradients, and chemical abundances of α-elements in the inner two degrees of the Milky Way, as obtained by recent IR spectroscopic surveys.
Methods. We used a compilation of recent measurements of metallicities and α-element abundances derived from medium-high resolution spectroscopy. We compare these metallicities with low-resolution studies.
Results. Defining “metal-rich” as stars with [Fe/H] >  0, and “metal-poor” as stars with [Fe/H] <  0, we find compelling evidence for a higher fraction (∼80%) of metal-rich stars in the Galactic Center (GC) compared to the values (50–60%) measured in the low latitude fields within the innermost 600 pc. The high fraction of metal-rich stars in the GC region implies a very high mean metallicity of +0.2 dex, while in the inner 600 pc of the bulge the mean metallicity is rather homogenous around the solar value. A vertical metallicity gradient of −0.27 dex kpc−1 in the inner 600 pc is only measured if the GC is included, otherwise the distribution is about flat and consistent with no vertical gradient.
Conclusions. In addition to its high stellar density, the Galactic center/nuclear star cluster is also extreme in hosting high stellar abundances, compared to the surrounding inner bulge stellar populations; this has implications for formation scenarios and strengthens the case for the nuclear star cluster being a distinct stellar system.
