description: The third-order elastic moduli and pressure derivatives of the second-order elastic constants of novel B2-type AlRE (RE=Y, Pr, Nd, Tb, Dy, Ce) intermetallics are presented from first-principles calculations. The elastic moduli are obtained from the coefficients of the polynomials from the nonlinear least-squares fitting of the energy-strain functions. The calculated second-order elastic constants of AlRE intermetallics are consistent with the previous calculations. To judge that our computational accuracy is reasonable, the calculated third-order constants of Al are compared with the available experimental data and other theoretical results and found very good agreement. In comparison with the theory of the linear elasticity, the third-order effects are very important with the finite strains are lager than approximately 3.5%. Finally, the pressure derivative has been discussed.

description: We show that every irreducible toroidal integer homology sphere graph manifold has a left-orderable fundamental group. This is established by way of a specialization of a result due to Bludov and Glass for the almagamated products that arise, and in this setting work of Boyer, Rolfsen and Wiest may be applied. Our result then depends on input from 3-manifold topology and Heegaard Floer homology.

description: A wide variety of approaches to estimate the degree of synchrony between two or more spike trains have been proposed. One of the most recent methods is the ISI-distance which extracts information from the interspike intervals (ISIs) by evaluating the ratio of the instantaneous firing rates. In contrast to most previously proposed measures it is parameter free and time-scale independent. However, it is not well suited to track changes in synchrony that are based on spike coincidences. Here we propose the SPIKE-distance, a complementary measure which is sensitive to spike coincidences but still shares the fundamental advantages of the ISI-distance. In particular, it is easy to visualize in a time-resolved manner and can be extended to a method that is also applicable to larger sets of spike trains. We show the merit of the SPIKE-distance using both simulated and real data.

description: We report on the use of a single NV center to probe fluctuating AC magnetic fields. Using engineered currents to induce random changes in the field amplitude and phase, we show that stochastic fluctuations reduce the NV center sensitivity and, in general, make the NV response field-dependent. We also introduce two modalities to determine the field spectral composition, unknown a priori in a practical application. One strategy capitalizes on the generation of AC-field-induced coherence 'revivals', while the other approach uses the time-tagged fluorescence intensity record from successive NV observations to reconstruct the AC field spectral density. These studies are relevant for magnetic sensing in scenarios where the field of interest has a non-trivial, stochastic behavior, such as sensing unpolarized nuclear spin ensembles at low static magnetic fields.

description: The observation of massive exoplanets at large separation from their host star, like in the HR 8799 system, challenges theories of planet formation. A possible formation mechanism involves the fragmentation of massive self-gravitating discs into clumps. While the conditions for fragmentation have been extensively studied, little is known of the subsequent evolution of these giant planet embryos, in particular their expected orbital migration. Assuming a single planet has formed by fragmentation, we investigate its interaction with the gravitoturbulent disc it is embedded in. Two-dimensional hydrodynamical simulations are used with a simple prescription for the disc cooling. A steady gravitoturbulent disc is first set up, after which simulations are restarted including a planet with a range of masses approximately equal to the clump's initial mass expected in fragmenting discs. Planets rapidly migrate inwards, despite the stochastic kicks due to the turbulent density fluctuations. We show that the migration timescale is essentially that of type I migration, with the planets having no time to open a gap. In discs with aspect ratio ~ 0.1 at their forming location, planets with a mass comparable to, or larger than Jupiter's can migrate in as short as 10000 years, that is, about 10 orbits at 100 AU. Massive planets formed at large separation from their star by gravitational instability are thus unlikely to stay in place, and should rapidly migrate towards the inner parts of protoplanetary discs, regardless of the planet mass.

description: We used the Australia Telescope Compact Array to map a large field of approximately $2^{\circ} \times 2^{\circ}$ around the Sculptor group galaxy NGC~300 in the 21-cm line emission of neutral hydrogen. We achieved a $5 σ$ \ion{H}{i} column density sensitivity of $10^{19}~\mathrm{cm}^{-2}$ over a spectral channel width of $8~\mathrm{km \, s}^{-1}$ for emission filling the $180'' \times 88''$ synthesised beam. The corresponding \ion{H}{i} mass sensitivity is $1.2 \times 10^{5}~\mathrm{M}_{\odot}$, assuming a distance of $1.9~\mathrm{Mpc}$. For the first time, the vast \ion{H}{i} disc of NGC~300 has been mapped over its entire extent at a moderately high spatial resolution of about $1~\mathrm{kpc}$. NGC~300 is characterised by a dense inner \ion{H}{i} disc, well aligned with the optical disc of $290^{\circ}$ orientation angle, and an extended outer \ion{H}{i} disc with a major axis of more than $1^{\circ}$ on the sky (equivalent to a diameter of about $35~\mathrm{kpc}$) and a different orientation angle of $332^{\circ}$. A significant fraction (about 43~per cent) of the total detected \ion{H}{i} mass of $1.5 \times 10^{9}~\mathrm{M}_{\odot}$ resides within the extended outer disc. We fitted a tilted ring model to the velocity field of NGC~300 to derive the rotation curve out to a radius of $18.4~\mathrm{kpc}$, almost twice the range of previous rotation curve studies. The rotation curve rises to a maximum velocity of almost $100~\mathrm{km \, s}^{-1}$ and then gently decreases again in the outer disc beyond a radius of about $10~\mathrm{kpc}$. Mass models fitted to the derived rotation curve yield good fits for Burkert and NFW dark matter halo models, whereas pseudo-isothermal halo models and MOND-based models both struggle to cope with the declining rotation curve. We also observe significant asymmetries in the outer \ion{H}{i} disc of NGC~300, in particular near the edge of the disc, which are possibly due to ram pressure stripping of gas by the intergalactic medium (IGM) of the Sculptor group. Our estimates show that ram pressure stripping can occur under reasonable assumptions on the density of the IGM and the relative velocity of NGC~300. The asymmetries in the gas disc suggest a proper motion of NGC~300 toward the south-east. At the same time, our data exclude IGM densities of significantly higher than $10^{-5}~\mathrm{cm}^{-3}$ in the vicinity of NGC~300, as otherwise the outer gas disc would have been stripped.

description: Initial diagnoses of any cancer can be a difficult process to overcome for many cancer patients. The thought of immediately dying, not being able to complete life goals, or leaving precious family behind often create significant amounts of unnecessary stress. Even when cancer patients agree to undergo chemotherapy cycles, they often have to prepare themselves to receive additional supportive care therapy to mitigate common side effects associated with cytotoxic doses of chemotherapy. Depending on the type of cancer, many patients undergo various chemotherapy combination drugs to treat their specific type of malignancy. Most of the chemotherapy regimens have very similar side effects often requiring EMLA cream to reduce inflammation of a port placement, post chemotherapy administration of Nuelasta® for imminent neutropenia, as well as Compazine® and Decadron® for chemotherapy induced nausea/vomiting2.

description: (2,8)Conclusion and Recommendations:Auryxia is comparable to other non-calcium based phosphate binders in terms of efficacy and price. The major advantage of Auryxia includes the studies supporting the reduction in use of IV iron and ESAs. An additional study utilizing Lewis et al. trial projected a cost savings of $2,101 per patient per year with approximately $1,585 of the savings directly related from less use of ESAs. Since CKD is a chronic disease requiring regular use of IViron and ESAs, the study states that cost savings could continue for the entire duration of treating a CKD patientAuryxia is a safe and effective phosphate binder with limited side effects and limited drug interactions. It has the potential to reduce IV iron use and ESA usage which could potentially impact cost savings.
Habermas sans culottes

Publisher: name: University of British Columbia
Year: 2014

description: In this thesis I formulate a critique of Habermas’s reading of the French Revolution in his book on the Strukturwandel der Öffentlichkeit, in order to argue that the emergence of the public sphere of the French Revolution cannot be limited to written and oral speech, but that it also included material culture such as clothing and its symbolical weight in public debate, as in the case of the sans-culottes. The first part of my thesis explores Arendt’s understanding of the public sphere as a “space of appearance,” as it relates to material culture and to her allusion to the sans-culottes, to show the theoretical limitations of Habermas’s rationalistic insistence on oral and written speech. The second part analyzes Habermas’s treatement of clothing as a public manifestation in the Middle Ages, which leads to the third part where I examine how Habermas missed the importance of clothing in the public “space of appearance” of the French Revolution and how the sans-culottes exemplified the public significance of clothing. The fourth part takes the example of the sans-culottes’s red cap and argues that considering this republican piece of clothing of Roman origin reveals how, in light of Arendt, tradition and modernity stood right beside each other in the French Revolution, which corresponds to a historical reality avoided by Habermas due to his insistence on the modernity of the Enlightenment.

description: In this study, we are interested primarily in how a structural factor – social capital – relates to Chinese national government agencies’ partner selection in environmental protection. Our study finds that their partner selection is associated positively with activity closure and popularity closure while being negatively influenced by cyclicity closure. Moreover, their partner selection is characterized predominantly by a leading-agency coordinated collaboration model, which favors the engagement of a shared third agency and emphasizes the similarity of interests. This study expands the theoretical connotations of social capital and provides new insights into the mechanisms underlying actors’ partner selection in interagency collaboration.

description: In 1998, Shibata and Sasaki [Phys. Rev. D 58, 104011 (1998)] presented an approximate analytical formula for the radius of the innermost stable circular orbit (ISCO) of a neutral test particle around a massive, rotating and deformed source. In the present paper, we generalize their expression by including the magnetic dipole moment. We show that our approximate analytical formulas are accurate enough by comparing them with the six-parametric exact solution calculated by Pachón et. al. [Phys. Rev. D 73, 104038 (2006)] along with the numerical data presented by Berti and Stergioulas [MNRAS 350, 1416 (2004)] for realistic neutron stars. As a main result, we find that in general, the radius at ISCO exhibits a decreasing behavior with increasing magnetic field. However, for magnetic fields below 100GT the variation of the radius at ISCO is negligible and hence the non-magnetized approximate expression can be used. In addition, we derive approximate analytical formulas for angular velocity, energy and angular momentum of the test particle at ISCO.

On the understanding of pulsations in the atmosphere of roAp stars: phase diversity and false nodes

description: Studies based on high-resolution spectroscopic data of rapidly oscillating Ap stars show a surprising diversity of pulsation behavior in the atmospheric layers, pointing, in particular, to the co-existence of running and standing waves. The correct interpretation of these data requires a careful modelling of pulsations in these magnetic stars. In light of this, in this work we present a theoretical analysis of pulsations in roAp stars, taking into account the direct influence of the magnetic field. We derive approximate analytical solutions for the displacement components parallel and perpendicular to the direction of the magnetic field, that are appropriate to the outermost layer. From these, we determine the expression for the theoretical radial velocity for an observer at a general position, and compute the corresponding pulsation amplitude and phase as function of height in the atmosphere. We show that the integral for the radial velocity has contributions from three different types of wave solutions, namely, running waves, evanescent waves, and standing waves of nearly constant amplitude. We then consider a number of case studies to illustrate the origin of the different pulsational behaviour that is found in the observations. Concerning pulsation amplitude, we find that it generally increases with atmospheric height. Pulsation phase, however, shows a diversity of behaviours, including phases that are constant, increasing, or decreasing with atmospheric height. Finally, we show that there are situations in which the pulsation amplitude goes through a zero, accompanied by a phase jumps of $π$, and argue that such behaviour does not correspond to a pulsation node in the outermost layers of the star, but rather to a visual effect, resulting from the observers inability to resolve the stellar surface.

description: We discuss interaction of strongly correlated electrons (described within the Hubbard model solved by dynamical mean-field theory (DMFT)) with Debye and Einstein phonons using recently developed DMFT+Sigma computational scheme. Electron-phonon interaction (EPI) is analyzed in adiabatic approximation (assuming the validity of Migdal theorem), allowing the neglect of EPI vertex corrections. This approach is valid for EPI coupling constant L < e_F/w_ph~10, where e_F is Fermi energy and w_ph is Debye or Einstein frequency. For moderate values of L only small changes in the electronic density of states are observed in DMFT+Sigma approximation for both weakly and strongly correlated metallic regimes. Metal-insulator (Mott) transition due to the increase of Hubbard interaction U is slightly inhibited by EPI. Our main aim is to discuss the interplay of "kinks" in electronic dispersion due to EPI and recently discovered kinks of electronic origin. For the certain region of model parameters coexistence of phonon "kinks" in electronic dispersion with purely electronic "kinks" is readily observed and we formulate some simple criteria of such coexistence. However, for most general combinations of model parameters phonon "kinks" make electronic "kinks" hardly observable. In the general case an increase of Hubbard interaction U rapidly suppresses the slope of electronic dispersion within the phonon "kink". These results are important for deeper understanding of the shape and evolution of electronic dispersions in strongly correlated systems such as copper oxides, where different kinds of "kinks" were recently observed in ARPES experiments.

description: Universal collision rate constants are calculated for ultracold collisions of two like bosonic or fermionic heteronuclear alkali-metal dimers involving the species Li, Na, K, Rb, or Cs. Universal collisions are those for which the short range probability of a reactive or quenching collision is unity such that a collision removes a pair of molecules from the sample. In this case, the collision rates are determined by universal quantum dynamics at very long range compared to the chemical bond length. We calculate the universal rate constants for reaction of the reactive dimers in their ground vibrational state $v=0$ and for vibrational quenching of non-reactive dimers with $v \ge 1$. Using the known dipole moments and estimated van der Waals coefficients of each species, we calculate electric field dependent loss rate constants for collisions of molecules tightly confined to quasi-two-dimensional geometry by a one-dimensional optical lattice. A simple scaling relation of the quasi-two-dimensional loss rate constants with dipole strength, trap frequency and collision energy is given for like bosons or like fermions. It should be possible to stabilize ultracold dimers of any of these species against destructive collisions by confining them in a lattice and orienting them with electric field of less than 20 kV/cm.

description: LDA+DMFT+Sigma_k approach was applied to describe pseudogap phase of several prototype high-Tc compounds e.g. hole doped Bi2212 and LSCO systems and electron doped NCCO and PCCO, demonstrating qualitative difference of the Fermi surfaces (FS) for these systems. Namely for Bi2212 and LSCO the so called "hot-spots" (intersection of a bare FS and AFM Brillouin zone (BZ) boundary), where scattering on pseudogap fluctuations is most intensive were not observed. Instead here we have Fermi arcs with smeared FS close to the BZ boundary. However for NCCO and PCCO "hot-spots" are clearly visible. This qualitative difference is shown to have material specific origin. Good agreement with known ARPES data was demon strated not only for FS maps but also for spectral function maps (quasiparticle bands in cluding lifetime and interaction broadening).

Role of microRNA in zinc depletion-induced growth inhibition in mouse fibroblast 3T3 cells
Creators: name: He, Li
Publisher: name: University of British Columbia
Year: 2014

description: Zinc, an essential trace element for humans, exerts many physiological functions, including its indispensible role in growth. Dietary zinc deficiency in children results in growth retardation. However, the mechanism whereby zinc regulates growth remains unclear. MicroRNAs are a group of newly discovered, small, non-coding RNAs and have been demonstrated to play a regulatory role in cell proliferation. The expression of microRNA and process of producing mature microRNA can be influenced by cellular and tissue zinc status. Thus, the hypothesis for my research is that microRNA plays a role in mediating zinc-dependent cell proliferation. The overall objective was to determine whether microRNAs are involved in zinc-dependent cell proliferation in mouse fibroblast 3T3 cells. 3T3 cells were cultured in Dulbecco’s Modified Eagle Medium with 10% fetal bovine serum (FBS) for 3 days. To deplete intracellular zinc, cells were cultured in the same media containing 5% (v/v) dimethyl sulfoxide (DMSO, control) or N,N,N’,N’- tetrakis(2-pyridylmethyl)ethylenediamine (TPEN, 2.5 μM) for 24 or 48 h with or without induction of quiescence (aphidicolin, 0.5 μg/ml; 24 h). To establish zinc-dependent effect, zinc was replenished at the final concentration of 0 (TPEN only), 1.25, 2.5 or 5 μM for 24 or 48 h. Cell proliferation was measured by cell cycle analysis using flow cytometry. MicroRNA expression profile was assessed by microRNA microarray. In the absence of quiescence induction, zinc-depletion for 24 or 48 h inhibited cell proliferation by 10.4% and 16.0% compared to control. In the presence of quiescence induction, zinc-depletion inhibited cell proliferation by 52.9%. Regardless of the status of quiescence, zinc replenishment at 1.25 μM nearly brought cell proliferation back to the level observed in the DMSO control, showing a zinc-dependent cell proliferation in 3T3 cells. Zinc-depletion increased the abundance of miR-132-3p, miR-212-3, and let-7e-3p, while zinc replenishment brought back the abundance of these three microRNAs to the level observed in the DMSO control. Interestingly, zinc-depletion decreased the abundance of miR-145b, and its abundance was increased after zinc replenishment. Overall, it appeared that microRNA played a role in zinc-mediated growth regulation in 3T3 cells; however, this role of microRNA remains to be affirmed by further investigation.
Does Young's equation hold on the nanoscale? A Monte Carlo test for the binary Lennard-Jones fluid

description: When a phase-separated binary ($A+B$) mixture is exposed to a wall, that preferentially attracts one of the components, interfaces between A-rich and B-rich domains in general meet the wall making a contact angle $θ$. Young's equation describes this angle in terms of a balance between the $A-B$ interfacial tension $γ_{AB}$ and the surface tensions $γ_{wA}$, $γ_{wB}$ between, respectively, the $A$- and $B$-rich phases and the wall, $γ_{AB} \cos θ=γ_{wA}-γ_{wB}$. By Monte Carlo simulations of bridges, formed by one of the components in a binary Lennard-Jones liquid, connecting the two walls of a nanoscopic slit pore, $θ$ is estimated from the inclination of the interfaces, as a function of the wall-fluid interaction strength. The information on the surface tensions $γ_{wA}$, $γ_{wB}$ are obtained independently from a new thermodynamic integration method, while $γ_{AB}$ is found from the finite-size scaling analysis of the concentration distribution function. We show that Young's equation describes the contact angles of the actual nanoscale interfaces for this model rather accurately and location of the (first order) wetting transition is estimated.

Probing the entanglement and locating knots in ring polymers: a comparative study of different arc closure schemes

description: The interplay between the topological and geometrical properties of a polymer ring can be clarified by establishing the entanglement trapped in any portion (arc) of the ring. The task requires to close the open arcs into a ring, and the resulting topological state may depend on the specific closure scheme that is followed. To understand the impact of this ambiguity in contexts of practical interest, such as knot localization in a ring with non trivial topology, we apply various closure schemes to model ring polymers. The rings have the same length and topological state (a trefoil knot) but have different degree of compactness. The comparison suggests that a novel method, termed the minimally-interfering closure, can be profitably used to characterize the arc entanglement in a robust and computationally-efficient way. This closure method is finally applied to the knot localization problem which is tackled using two different localization schemes based on top-down or bottom-up searches.

description: We present optical spectroscopy of two samples of GALEX grism selected Ly alpha emitters (LAEs): one at z=0.195-0.44 and the other at z=0.65-1.25. We have also observed a comparison sample of galaxies in the same redshift intervals with the same UV magnitude distributions but with no detected Ly alpha. We use the optical spectroscopy to eliminate active galactic nuclei (AGNs) and to obtain the optical emission-line properties of the samples. We compare the luminosities of the LAEs in the two redshift intervals and show that there is dramatic evolution in the maximum Ly alpha luminosity over z=0-1. Focusing on the z=0.195-0.44 samples alone, we show that there are tightly defined relations between all of the galaxy parameters and the rest-frame equivalent width (EW) of H alpha. The higher EW(H alpha) sources all have lower metallicities, bluer colors, smaller sizes, and less extinction, consistent with their being in the early stages of the galaxy formation process. We find that 75 +- 12% of the LAEs have EW(H alpha)>100 Angstrom, and, conversely, that 31 +/- 3% of galaxies with EW(H alpha)>100 Angstrom are LAEs. We correct the broadband magnitudes for the emission-line contributions and use spectral synthesis fits to estimate the ages of the galaxies. We find a median age of 1.1x10^{8} yr for the LAE sample and 1.4x10^{9} yr for the UV-continuum sample without detected Ly alpha. The median metallicity of the LAE sample is 12+log(O/H)=8.24, or about 0.4 dex lower than the UV-continuum sample.

description: In this paper we review Castagnino's contributions to the foundations of quantum mechanics. First, we recall his work on quantum decoherence in closed systems, and the proposal of a general framework for decoherence from which the phenomenon acquires a conceptually clear meaning. Then, we introduce his contribution to the hard field of the interpretation of quantum mechanics: the modal-Hamiltonian interpretation solves many of the interpretive problems of the theory, and manifests its physical relevance in its application to many traditional models of the practice of physics. In the third part of this work we describe the ontological picture of the quantum world that emerges from the modal-Hamiltonian interpretation, stressing the philosophical step toward a deep understanding of the reference of the theory.

description: We demonstrate a technique for achieving spectral resonance between a polarization-degenerate micropillar cavity mode and an embedded quantum dot transition. Our approach is based on a combination of isotropic and anisotropic tensile strain effected by laser-induced surface defects, thereby providing permanent tuning. Such a technique is a prerequisite for the implementation of scalable quantum information schemes based on solid-state cavity quantum electrodynamics.

Observational Constraints to Ricci Dark Energy Model by Using: SN, BAO, OHD, fgas Data Sets

Publisher: name: arXiv

description: In this paper, we perform a global constraint on the Ricci dark energy model with both the flat case and the non-flat case, using the Markov Chain Monte Carlo (MCMC) method and the combined observational data from the cluster X-ray gas mass fraction, Supernovae of type Ia (397), baryon acoustic oscillations, current Cosmic Microwave Background, and the observational Hubble function. In the flat model, we obtain the best fit values of the parameters in $1σ, 2σ$ regions: $Ω_{m0}=0.2927^{+0.0420 +0.0542}_{-0.0323 -0.0388}$, $α=0.3823^{+0.0331 +0.0415}_{-0.0418 -0.0541}$, $Age/Gyr=13.48^{+0.13 +0.17}_{-0.16 -0.21}$, $H_0=69.09^{+2.56 +3.09}_{-2.37 -3.39}$. In the non-flat model, the best fit parameters are found in $1σ, 2σ$ regions:$Ω_{m0}=0.3003^{+0.0367 +0.0429}_{-0.0371 -0.0423}$, $α=0.3845^{+0.0386 +0.0521}_{-0.0474 -0.0523}$, $Ω_k=0.0240^{+0.0109 +0.0133}_{-0.0130 -0.0153}$, $Age/Gyr=12.54^{+0.51 +0.65}_{-0.37 -0.49}$, $H_0=72.89^{+3.31 +3.88}_{-3.05 -3.72}$. Compared to the constraint results in the $Λ\textmd{CDM}$ model by using the same datasets, it is shown that the current combined datasets prefer the $Λ\textmd{CDM}$ model to the Ricci dark energy model.
