“Please Clap”: Applause, Laughter, and Booing during the 2016 GOP Presidential Primary Debates
Authors: Stewart Patrick A. , Eubanks Austin D. , Miller Jason 
Published: October 2016

ABSTRACTThe 2016 Republican Party presidential primary debates were unprecedented in the amount of media and public interest they generated. Substantially driven by curiosity about reality television celebrity Donald Trump, the initial debates hosted by FOX News and CNN both reflected and validated interest in his candidacy while proffering attention to a full slate of more traditional presidential contenders in front of boisterous audiences. This study considers these audiences’ response. Whether applause, laughter, booing, or combinations thereof, these group utterances provide a reliable metric by which insights may be derived concerning partisan attitudes towards Trump and the other candidates, as well as the unity of the Republican Party. Findings suggest that the debate setting in concert with the demographics of the in-person audience may well have influenced initial response to the candidates and as a result have subtle yet lingering consequences for the 2016 presidential election.
Who Decides When The Party Doesn’t? Authoritarian Voters and the Rise of Donald Trump
Authors: MacWilliams Matthew C. 
Published: October 2016

ABSTRACTWhile the party decides theory explains the outcomes of past nomination battles for president, this year in the Republican presidential contest party insiders failed to anoint a standard bearer. Who decides when the party elites don’t? In 2016, it was America’s authoritarian voters. And their candidate of choice, Donald Trump, is anathema to party leaders. I argue that Trump’s rise is in part the result of authoritarian voters’ response to his unvarnished, us-versus-them rhetoric. The failure of Republican Party insiders to coalesce behind one candidate opened the door for Trump. Authoritarian-driven partisan polarization (Hetherington and Weiler 2009), increasing fear of real and imagined threats, and terrorist incidents abroad and at home provided the fuel for Trump’s campaign. And Trump’s message and manner ignited that fuel, propelling him to the Republican nomination for president.
The Growing Spatial Polarization of Presidential Voting in the United States, 1992–2012: Myth or Reality?
Authors: Johnston Ron , Jones Kelvyn , Manley David 
Published: October 2016

ABSTRACTThere has been considerable debate regarding a hypothesis that the American electorate has become spatially more polarized over recent decades. Using a new method for measuring polarization, this paper evaluates that hypothesis regarding voting for the Democratic party’s presidential candidates at six elections since 1992, at three separate spatial scales. The findings are unambiguous: polarization has increased substantially across the country’s nine census divisions, across the 49 states within those divisions, and across the 3,077 counties within the states—with the most significant change at the finest of those three scales.
Harry Potter and the Deathly Donald
Authors: Mutz Diana C. 
Published: October 2016

ABSTRACTFew empirical studies suggest that fictional stories can influence political opinions. Nonetheless, in this study I demonstrate the relevance of Harry Potter consumption to oppositional attitudes toward Donald Trump and his worldview. Using multivariate observational models and panel data from 2014 to 2016, results suggest that the lessons of the Harry Potter series have influenced levels of opposition to punitive policies and support for tolerance of groups considered outside the American mainstream. Further, they predict public reactions to Donald Trump above and beyond their influence on policies consistent with his views.
Rejecting More of the Same? The 2016 Veepstakes
Authors: Baumgartner Jody C 
Published: October 2016

ABSTRACTIn this article, I present results from a conditional logit model of vice presidential selection that predicts the selection of vice presidential candidates for both Hillary Clinton and Donald Trump in 2016. Examining contested major party vice presidential nominations from 1960 through 2012, the model finds media exposure, political experience, military service, age, and demographic (gender/racial/ethnic) diversity to be significant factors in the selection process. In the end, the model correctly predicts 15 of the 21 (71.%) contested major party nominations during this period. For 2016 the model correctly and convincingly predicts Mike Pence as Donald Trump’s selection, but incorrectly predicts Cory Booker as Hillary Clinton’s pick. This reduces the overall percentage of correct predictions from 1960 to 2016 to 69.6% (16 of 23), but the approach taken here still represents a more appropriate way for social scientists to think about what factors drive vice presidential selection.
The quest for collapsed/frozen stars in single-line spectroscopic binary systems
Authors: Trimble Virginia 
Published: October 2016

AbstractBlack holes are now commonplace, among the stars, in Galactic centers, and perhaps other places. But within living memory, their very existence was doubted by many, and few chose to look for them. Zeldovich and Guseinov were first, followed by Trimble and Thorne, using a method that would have identified HDE 226868 as a plausible candidate, if it had been in the 1968 catalogue of spectroscopic binaries. That it was not arose from an unhappy accident in the observing program of Daniel M. Popper long before the discovery of X-ray binaries and the identification of Cygnus X-1 with that hot, massive star and its collapsed companion.
The Zeldovich & Adhesion approximations and applications to the local universe
Authors: Hidding Johan , van de Weygaert Rien , Shandarin Sergei 
Published: October 2016

AbstractThe Zeldovich approximation (ZA) predicts the formation of a web of singularities. While these singularities may only exist in the most formal interpretation of the ZA, they provide a powerful tool for the analysis of initial conditions. We present a novel method to find the skeleton of the resulting cosmic web based on singularities in the primordial deformation tensor and its higher order derivatives. We show that the A3 lines predict the formation of filaments in a two-dimensional model. We continue with applications of the adhesion model to visualise structures in the local (z < 0.03) universe.
Structure of the Canes Venatici I cloud of galaxies
Authors: Makarov Dmitry I. , Makarova Lidia N. , Uklein Roman I. 
Published: October 2016

AbstractWe study the spatial distribution of the sparse cloud of galaxies in the Canes Venatici constellation. We determined distances of 30 galaxies using the tip of the red giant branch (TRGB) method. This homogeneous sample allows us to distinguish the zone of chaotic motions around the center of the system. A group of galaxies around M94 is characterized by the mass-luminosity ratio of M/LB=159 (M/L)⊙. It is significantly higher than the typical ratio M/LB=159 (M/L)⊙ for the nearby groups of galaxies. The CVn I cloud of galaxies contains 4–5 times less luminous matter compared with the well-known nearby groups, such as the Local Group, M 81 and Centaurus A. The central galaxy M 94 is at least 1 mag fainter than any other central galaxy of these groups. However, the concentration of galaxies in the Canes Venatici may have a comparable total mass.
Environmental density of galaxies from SDSS via Voronoi tessellation
Authors: Dobrycheva D. , Melnyk O. , Elyiv A. , Vavilova I. 
Published: October 2016

AbstractThe aim of our work was to determine the environmental density of galaxies from SDSS DR9 using the Voronoi tessellation. We constructed the 3D Voronoi tessellation for the volume-limited galaxy sample within 0.02 <z<0.1 and -24 Mr-20.7 using an inverse volume of Voronoi cell as a parameter describing the local environmental density of a galaxy. It allowed us to inspect the morphology - density relation. We obtained that the early type galaxies prefer to reside in the Voronoi cells of smaller volumes (i.e. dense environments) than the late type galaxies, which are located in the larger Voronoi cells (i.e. sparse environments).
Luminosity function for galaxy clusters

Published: October 2016

AbstractWe constructed and studied the luminosity function of 6188 galaxy
clusters. This was performed by counting brightness of galaxies
belonging to clusters in the PF catalogue, taking galaxy data from
MRSS. Our result shows that the investigated structures are
characterized by a luminosity function different from that of
optical galaxies and radiogalaxies (Machalski & Godłowski
2000). The implications of this result for theories
of galaxy formation are briefly discussed.
Testing Gravity using Void Profiles
Authors: Cai Yan-Chuan , Padilla Nelson , Li Baojiu 
Published: October 2016

AbstractWe investigate void properties inf(R)models using N-body simulations, focusing on their differences from General Relativity (GR) and their detectability. In the Hu-Sawickif(R)modified gravity (MG) models, the halo number density profiles of voids are not distinguishable from GR. In contrast, the samef(R)voids are more empty of dark matter, and their profiles are steeper. This can in principle be observed by weak gravitational lensing of voids, for which the combination of a spectroscopic redshift and a lensing photometric redshift survey over the same sky is required. Neglecting the lensing shape noise, thef(R)model parameter amplitudesfR0=10-5and 10-4may be distinguished from GR using the lensing tangential shear signal around voids by 4 and 8 σ for a volume of 1 (Gpc/h)3. The line-of-sight projection of large-scale structure is the main systematics that limits the significance of this signal for the near future wide angle and deep lensing surveys. For this reason, it is challenging to distinguishfR0=10-6from GR. We expect that this can be overcome with larger volume. The halo void abundance being smaller and the steepening of dark matter void profiles inf(R)models are unique features that can be combined to break the degeneracy betweenfR0and σ8.

Published: October 2016

AbstractWe present the structural and star formation properties of 59 void galaxies as part of the Void Galaxy Survey (VGS). Our aim is to study in detail the physical properties of these void galaxies and study the effect of the void environment on galaxy properties. We use Spitzer 3.6μ and B-band imaging to study the morphology and color of the VGS galaxies. For their star formation properties, we use Hα and GALEX near-UV imaging. We compare our results to a range of galaxies of different morphologies in higher density environments. We find that the VGS galaxies are in general disk dominated and star forming galaxies. Their star formation rates are, however, often less than 1 M⊙ yr-1. There are two early-type galaxies in our sample as well. In reversus MBparameter space, VGS galaxies occupy the same space as dwarf irregulars and spirals.
Microbial legacies alter decomposition in response to simulated global change

AbstractTerrestrial ecosystem models assume that microbial communities respond instantaneously, or are immediately resilient, to environmental change. Here we tested this assumption by quantifying the resilience of a leaf litter community to changes in precipitation or nitrogen availability. By manipulating composition within a global change experiment, we decoupled the legacies of abiotic parameters versus that of the microbial community itself. After one rainy season, more variation in fungal composition could be explained by the original microbial inoculum than the litterbag environment (18% versus 5.5% of total variation). This compositional legacy persisted for 3 years, when 6% of the variability in fungal composition was still explained by the microbial origin. In contrast, bacterial composition was generally more resilient than fungal composition. Microbial functioning (measured as decomposition rate) was not immediately resilient to the global change manipulations; decomposition depended on both the contemporary environment and rainfall the year prior. Finally, using metagenomic sequencing, we showed that changes in precipitation, but not nitrogen availability, altered the potential for bacterial carbohydrate degradation, suggesting why the functional consequences of the two experiments may have differed. Predictions of how terrestrial ecosystem processes respond to environmental change may thus be improved by considering the legacies of microbial communities.

AbstractHuman induced pluripotent stem cells (iPSCs) can provide a promising source of midbrain dopaminergic (mDA) neurons for cell replacement therapy for Parkinson’s disease (PD). However, iPSC-derived donor cells inevitably contain tumorigenic or inappropriate cells. To eliminate these unwanted cells, cell sorting using antibodies for specific markers such as CORIN or ALCAM has been developed, but neither marker is specific for ventral midbrain. Here we employ a double selection strategy for cells expressing both CORIN and LMX1A::GFP, and report a cell surface marker to enrich mDA progenitors, LRTM1. When transplanted into 6-OHDA-lesioned rats, human iPSC-derived LRTM1+ cells survive and differentiate into mDA neurons in vivo, resulting in a significant improvement in motor behaviour without tumour formation. In addition, there was marked survival of mDA neurons following transplantation of LRTM1+ cells into the brain of an MPTP-treated monkey. Thus, LRTM1 may provide a tool for efficient and safe cell therapy for PD patients.

AbstractTopological insulators host spin-polarized surface states born out of the energetic inversion of bulk bands driven by the spin-orbit interaction. Here we discover previously unidentified consequences of band-inversion on the surface electronic structure of the topological insulator Bi2Se3. By performing simultaneous spin, time, and angle-resolved photoemission spectroscopy, we map the spin-polarized unoccupied electronic structure and identify a surface resonance which is distinct from the topological surface state, yet shares a similar spin-orbital texture with opposite orientation. Its momentum dependence and spin texture imply an intimate connection with the topological surface state. Calculations show these two distinct states can emerge from trivial Rashba-like states that change topology through the spin-orbit-induced band inversion. This work thus provides a compelling view of the coevolution of surface states through a topological phase transition, enabled by the unique capability of directly measuring the spin-polarized unoccupied band structure.
Decrease in pH destabilizes individual vault nanocages by weakening the inter-protein lateral interaction

Published: October 2016

AbstractVault particles are naturally occurring proteinaceous cages with promising application as molecular containers. The use of vaults as functional transporters requires a profound understanding of their structural stability to guarantee the protection and controlled payload delivery. Previous results performed with bulk techniques or at non-physiological conditions have suggested pH as a parameter to control vault dynamics. Here we use Atomic Force Microscopy (AFM) to monitor the structural evolution of individual vault particles while changing the pH in real time. Our experiments show that decreasing the pH of the solution destabilize the barrel region, the central part of vault particles and leads to the aggregation of the cages. Additional analyses using Quartz-Crystal Microbalance (QCM) and Differential Scanning Fluorimetry (DSF) are consistent with our single molecule AFM experiments. The observed topographical defects suggest that low pH weakens the bonds between adjacent proteins. We hypothesize that the observed effects are related to the strong polar character of the protein-protein lateral interactions. Overall, our study unveils the mechanism for the influence of a biologically relevant range of pHs on the stability and dynamics of vault particles.
Allosteric communication pathways routed by Ca2+/Mg2+ exchange in GCAP1 selectively switch target regulation modes
Authors: Marino Valerio , Dell’Orco Daniele 
Published: October 2016

AbstractGCAP1 is a neuronal calcium sensor protein that regulates the phototransduction cascade in vertebrates by switching between activator and inhibitor of the target guanylate cyclase (GC) in a Ca2+-dependent manner. We carried out exhaustive molecular dynamics simulations of GCAP1 and determined the intramolecular communication pathways involved in the specific GC activator/inhibitor switch. The switch was found to depend on the Mg2+/Ca2+ loading states of the three EF hands and on the way the information is transferred from each EF hand to specific residues at the GCAP1/GC interface. Post-translational myristoylation is fundamental to mediate long range allosteric interactions including the EF2-EF4 coupling and the communication between EF4 and the GC binding interface. Some hubs in the identified protein network are the target of retinal dystrophy mutations, suggesting that the lack of complete inhibition of GC observed in many cases is likely due to the perturbation of intra/intermolecular communication routes.
Experimental demonstration of a quantum shutter closing two slits simultaneously
Authors: Okamoto Ryo , Takeuchi Shigeki 
Published: October 2016

AbstractThe interference between two paths of a single photon at a double slit is widely considered to be the most paradoxical result of quantum theory. Here is a new interesting question to the phenomenon: can a single shutter simultaneously close two slits by effectively being in a superposition of different locations? Aharonov and Vaidman have shown that it is indeed possible to construct a quantum shutter that can close two slits and reflect a probe photon perfectly when its initial and final states are appropriately selected. Here we report the experimental demonstration of their proposal overcoming the difficulty to realize a ‘quantum shutter’ by employing photonic quantum routers. The reflectance ratio of 0.61 ± 0.027 surpasses the classical limit with 4.1 standard deviation, shedding new light on the unusual physical properties of quantum operations. This experimental demonstration, where the strong measurement and non-local superposition seem co-existing, provides an alternative to weak measurements as a way to explore the nature of quantum physics.

AbstractNephrolithiasis, secondary hyperparathyroidism (sHPT), and cardiovascular complications are associated with disturbances in Ca handling and contribute to morbidity/mortality during haemodialysis (HD). Calcimimetics, activators of the calcium-sensing receptor (CaSR), provide an effective means of reducing parathyroid hormone (PTH) secretion in sHPT. Polymorphism in CaSR gene (CASR) influences Ca-related parameters, however it was not shown in HD patients for CASR rs7652589. The minor allele at this polymorphism modifies the binding sites of transcription factors and CaSR expression. We hypothesized that CASR rs7652589 variants may also influence CaSR in end stage renal disease (ESRD). We aimed to determine the associations of rs7652589 with nephrolithiasis-related ESRD, Ca, P, ALP, PTH, response to treatment with cinacalcet, prevalence of coronary artery disease, and all-cause/cardiovascular mortality in HD patients (n = 1162). Healthy individuals (n = 918) were controls. This study shows that the A allele of rs7652589 is a risk allele for nephrolithiasis-related ESRD. The AA genotype is associated with more severe sHPT (higher Ca and PTH concentrations). The A allele is associated with reduced CaSR transcript level in peripheral blood mononuclear cells. According to computational analysis, potential binding sites for GLI3, AHR and TP53 are removed by the A allele, whereas binding sites for SOX18 and TP63 are created.

AbstractHeterogeneous catalysis, which is widely used in the chemical industry, makes a great use of supported late-transition-metal nanoparticles, and bimetallic catalysts often show superior catalytic performances as compared to their single metal counterparts. In order to optimize catalyst efficiency and discover new active combinations, an atomic-level understanding and control of the catalyst structure is desirable. In this work, the structure of catalytically active AuRh bimetallic nanoparticles prepared by colloidal methods and immobilized on rutile titania nanorods was investigated using aberration-corrected scanning transmission electron microscopy. Depending on the applied post-treatment, different types of segregation behaviours were evidenced, ranging from Rh core – Au shell to Janus via Rh ball – Au cup configuration. The stability of these structures was predicted by performing density-functional-theory calculations on unsupported and titania-supported Au-Rh clusters; it can be rationalized from the lower surface and cohesion energies of Au with respect to Rh, and the preferential binding of Rh with the titania support. The bulk-immiscible AuRh/TiO2 system can serve as a model to understand similar supported nanoalloy systems and their synergistic behaviour in catalysis.
