description: The cold dark matter (CDM) model of structure formation, normalized on large scales, leads to excessive pairwise velocity dispersions on small scales. In an attempt to circumvent this problem, we study three scenarios (all with $Ω=1$) which have more large-scale power and less small-scale power than the CDM model: 1) an admixture of cold and hot dark matter; 2) cold dark matter with a non-scale-invariant, power-law primordial power spectrum; and 3) cold dark matter with coupling of dark matter to a long-range vector field. Despite the {reduced} small-scale power, when such models are evolved in the nonlinear regime to large amplitude, the velocities on small scales are actually {\it increased} over CDM with the same value of $σ_8$. This `flip-over', in disagreement with the expectation from linear perturbation theory, arises from the nonlinear coupling of the extra power on large scales with shorter wavelengths. However, due to the extra large-scale power, the recent COBE DMR results indicate smaller amplitudes for these models, $σ_8 \sim 0.5 - 0.7$, than for CDM (for which $σ_8 \sim 1.2$). Therefore, when normalized to COBE on large scales, such models do lead to reduced velocities on small scales and they produce fewer halos compared with CDM. Quantitatively it seems, however, that models that produce sufficiently low small-scale velocities fail to produce an adequate distribution of halos.

description: There are now a half dozen young pulsars detected in high energy photons by the Compton GRO, showing a variety of emission efficiencies and pulse profiles. We present here a calculation of the pattern of high energy emission on the sky in a model which posits $γ$-ray production by charge depleted gaps in the outer magnetosphere. This model accounts for the radio to $γ$-ray pulse offsets of the known pulsars, as well as the shape of the high energy pulse profiles. We also show that $\sim 1/3$ of emitting young radio pulsars will not be detected due to beaming effects, while $\sim 2.5 \times$ the number of radio-selected $γ$-ray pulsars will be viewed only high energies. Finally we compute the polarization angle variation and find that the previously misunderstood optical polarization sweep of the Crab pulsar arises naturally in this picture. These results strongly support an outer-magnetosphere location for the $γ-$ray emission.

description: The effects of humidity on the electronic properties of quasi-free standing one layer graphene (QFS 1LG) are investigated via simultaneous magneto-transport in the van der Pauw geometry and local work function measurements in a controlled environment. QFS 1LG on 4H-SiC(0001) is obtained by hydrogen intercalation of the interfacial layer. In this system, the carrier concentration experiences a two-fold increase in sensitivity to changes in relative humidity as compared to the as-grown epitaxial graphene. This enhanced sensitivity to water is attributed to the lowering of the hydrophobicity of QFS 1LG, which results from spontaneous polarization of 4H-SiC(0001) strongly influencing the graphene. Moreover, the superior carrier mobility of the QFS 1LG system is retained even at the highest humidity. The work function maps constructed from Kelvin probe force microscopy also revealed higher sensitivity to water for 1LG compared to 2LG in both QFS 1LG and as-grown systems. These results point to a new field of applications for QFS 1LG, i.e., as humidity sensors, and the corresponding need for metrology in calibration of graphene-based sensors and devices.

Kohn anomaly of optical zone boundary phonons in uniaxial strained graphene: role of the electronic band structure

Subjects: subject: Mesoscale and Nanoscale Physics (cond-mat.mes-hall)

description: One of the unique properties of graphene is its extremely high mechanical strength. Several studies have shown that the mechanical failure of graphene sheet under a tensile strain is due to the enhancement of the Kohn anomaly of the zone boundary transverse optical phonon modes. In this work, we derive an analytical expression of the Kohn anomaly parameter $α_{\vec{K}}$ of these phonons in graphene deformed by a uniaxial strain along the armchair direction. We show that, the tilt of Dirac cones, induced by the strain, contributes to the enhancement of the Kohn anomaly under a tensile deformation and gives rise to a dominant contribution of the so-called {\it outer} intervalley mediated phonon processes. Moreover, the Kohn anomaly is found to be anisotropic with respect to the phonon wave vectors around the K point. This anisotropy may be at the origin of the light polarization dependence of the Raman 2D band of the strained graphene. Our results uncover, not only, the role of the Kohn anomaly in the anisotropic mechanical failure of the graphene sheet, under strains applied along the armchair and zigzag directions, but shed also light on the doping induced strengthening of strained graphene.

The semiclassical quantum correction under this wormhole spacetime yields Hawking radiation. It is expected, with the quantum back reaction added to the classical equation, that the information loss paradox may be resolved in this model.

Can We Identify Lensed Gamma Ray Bursts?

Publisher: name: arXiv
Year: 1994
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: A gravitationally lensed gamma-ray burst (GRB) would appear as multiple bursts with identical light curves, separated in time and differing only by the scaling of their amplitudes. However, noise may make them difficult to identify as lensed images. Furthermore, faint, intrinsically similar, yet distinct light curves may be falsely identified as lensing events. In this paper we develop two statistical tests to distinguish noisy burst light curves. We use Fourier analysis techniques to analyze the signals for both intrinsic variability and variability due to noise. We are able to determine the noise level, and we compare the bursts only at frequency channels that are signal dominated. Utilizing these methods, we are able to make quantitative statements about whether two bursts are distinct. We apply these statistics to scaled versions of two subbursts of GRB 910503--- subbursts previously investigated by Wambsganss (1993) using a different statistical test. We find that our methods are able to distinguish these bursts at slightly smaller amplitudes than those at which Wambsganss's method succeeds. We then apply our techniques to ``candidate" lensing events taken from the BATSE catalogue, and we find that nearly all of them, except for the very shortest ones (durations $\aproxlt 0.3 ~s$), are distinguishable. We therefore expect that a majority of bursts will be disinguishable from one another.

Crystal plasticity simulation of the effect of grain size on the fatigue behavior of polycrystalline Inconel 718

description: A microstructure-based model that accounts for the effect of grain size has been developed to study the effect of grain size on the fatigue life of Inconel 718 alloys. The fatigue behavior of two alloys with different grain size was determined by means of uniaxial cyclic deformation tests under fully-reversed deformation ($R_\varepsilon$ = -1) at 400$^\circ$C in the low cycle fatigue regime. The model was based in the determination of the fatigue indicator parameter (based on the local crystallographic strain energy dissipated per cycle) by means of computational homogenization of a representative volume element of the microstructure. The mechanical response of the single crystal within the polycrystal was modelled through a phenomenological crystal plasticity model which was modified to account for the effect of grain size on the monotonic and cyclic hardening/softening mechanisms. The microstructure-based crack initiation model parameters were calibrated from the experimental tests of the material with fine grain size. The results of the fatigue simulations were in good agreement with the experimental results in terms of the cyclic stress-strain curves and of the number of cycles for fatigue crack initiation. The model did not show any grain size effect on the fatigue life for the largest cyclic strain ranges while the predicted fatigue life predicted was considerably longer in the case of the microstructure with fine grain size for the lowest strain ranges, in quantitative agreement with experimental data. These differences were attributed to changes in the deformation modes between homogeneous plastic deformation at large cyclic strain ranges and localized plasticity in a few grains at low cyclic strain ranges.

description: Heterogeneous nucleation is studied by Monte Carlo simulations and phenomenological theory, using the two-dimensional lattice gas model with suitable boundary fields. A chemical inhomogeneity of length b at one boundary favors the liquid phase, while elsewhere the vapor is favored. Switching on the bulk field favoring the liquid, nucleation and growth of the liquid phase starting from the region of the chemical inhomogeneity is analyzed. Three regimes occur: for small fields, the critical droplet radius is so large that a critical droplet having the contact angle required by Young's equation in the region of the chemical inhomogeneity does not yet fit there, since the baseline length of the circle-cut sphere droplet would exceed b. For an intermedium regime of bulk fields, such droplets fit inside the inhomogeneity, and are indeed found in simulations with large enough observation times, but these droplets remain pinned to the chemical inhomogeneity when their baseline has grown to the length b. On general grounds one can predict that the effective contact angle as well as the excess density of the droplets, scaled by b^2, are functions of the product b and the bulk field, but do not depend on both variables separately. For larger fields the droplets nucleated at the chemical inhomogeneity grow to the full system size.

description: It is by now clear that the naive rule for the entropy of a black hole, {entropy} = 1/4 {area of event horizon}, is violated in many interesting cases. Indeed, several authors have recently conjectured that in general the entropy of a dirty black hole might be given purely in terms of some surface integral over the event horizon of that black hole. A formal proof of this conjecture, using Lorentzian signature techniques, has recently been provided by Wald. This note performs two functions. Firstly, a rather different proof of this result is presented --- a proof based on Euclidean signature techniques. The total entropy is S = 1/4 {k A_H / l_P^2} + \int_H {S} \sqrt{g} d^2x. The integration runs over a spacelike cross-section of the event horizon H. The surface entropy density, {S}, is related to the behaviour of the matter Lagrangian under time dilations. Secondly, I shall consider the specific case of Einstein-Hilbert gravity coupled to an effective Lagrangian that is an arbitrary function of the Riemann tensor (though not of its derivatives). In this case a more explicit result is obtained S = 1/4 {k A_H / l_P^2} + 4 pi {k/hbar} \int_H {partial L / partial R_{μνλρ}} g^\perp_{μλ} g^\perp_{νρ} \sqrt{g} d^2x . The symbol $g^\perp_{μν}$ denotes the projection onto the two-dimensional subspace orthogonal to the event horizon.

Do meteoritic silicon carbide grains originate from asymptotic giant branch stars of super-solar metallicity?

description: We compare literature data for the isotopic ratios of Zr, Sr, and Ba from analysis of single meteoritic stardust silicon carbide (SiC) grains to new predictions for the slow neutron-capture process (the s process) in metal-rich asymptotic giant branch (AGB) stars. The models have initial metallicities Z = 0.014 (solar) and Z = 0.03 (twice-solar) and initial masses 2 - 4.5 Msun, selected such as the condition C/O>1 for the formation of SiC is achieved. Because of the higher Fe abundance, the twice-solar metallicity models result in a lower number of total free neutrons released by the 13C(α,n)16O neutron source. Furthermore, the highest-mass (4 - 4.5 Msun) AGB stars of twice-solar metallicity present a milder activation of the 22Ne(α,n)25Mg neutron source than their solar metallicity counterparts, due to cooler temperatures resulting from the effect of higher opacities. They also have a lower amount of the 13C neutron source than the lower-mass models, following their smaller He-rich region. The combination of these different effects allows our AGB models of twice-solar metallicity to provide a match to the SiC data without the need to consider large variations in the features of the 13C neutron source nor neutron-capture processes different from the s process. This raises the question if the AGB parent stars of meteoritic SiC grains were in fact on average of twice-solar metallicity. The heavier-than-solar Si and Ti isotopic ratios in the same grains are in qualitative agreement with an origin in stars of super-solar metallicity because of the chemical evolution of the Galaxy. Further, the SiC dust mass ejected from C-rich AGB stars is predicted to significantly increase with increasing the metallicity.

description: Boson sampling (BS) is a multimode linear optical problem that is expected to be intractable on classical computers. It was recently suggested that molecular vibronic spectroscopy (MVS) is computationally as complex as BS. In this review, we discuss the correspondence relation between BS and MVS and briefly introduce the experimental demonstrations of the molecular spectroscopic process using quantum devices. The similarity of the two theories results in another BS setup, which is called "vibronic BS". The hierarchical structure of vibronic BS, which includes the original BS and other Gaussian BS, is also explained.

description: Usually inflation ends either by a slow rolling of the inflaton field, which gradually becomes faster and faster, or by a first-order phase transition. We describe a model where inflation ends in a different way, due to a very rapid rolling (`waterfall') of a scalar field $σ$ triggered by another scalar field $ϕ$. This model looks as a hybrid of chaotic inflation and the usual theory with spontaneous symmetry breaking. Another hybrid model to be discussed here uses some building blocks from extended inflation (Brans-Dicke theory), from new inflation (phase transition due to a non-minimal coupling of the inflaton field to gravity) and from chaotic inflation (the possibility of inflation beginning at large as well as at small $σ$). In the simplest version of this scenario inflation ends up by slow rolling, thus avoiding the big-bubble problem of extended inflation.

Our data includes evolutionary state, surface gravity, mean density, mass, radius, age, and the spectroscopic and asteroseismic measurements used to derive them. We employ a new empirical approach for combining asteroseismic measurements from different methods, calibrating the inferred stellar parameters, and estimating uncertainties. With high statistical significance, we find that asteroseismic parameters inferred from the different pipelines have systematic offsets that are not removed by accounting for differences in their solar reference values. We include theoretically motivated corrections to the large frequency spacing ($Δν$) scaling relation, and we calibrate the zero point of the frequency of maximum power ($ν_{\rm max}$) relation to be consistent with masses and radii for members of star clusters. For most targets, the parameters returned by different pipelines are in much better agreement than would be expected from the pipeline-predicted random errors, but 22\% of them had at least one method not return a result and a much larger measurement dispersion. This supports the usage of multiple analysis techniques for asteroseismic stellar population studies. The measured dispersion in mass estimates for fundamental calibrators is consistent with our error model, which yields median random and systematic mass uncertainties for RGB stars of order 4\%. Median random and systematic mass uncertainties are at the 9\% and 8\% level respectively for RC stars.

description: The hybrid Vlasov-Maxwell system of equations is suitable to describe a magnetized plasma at scales of the order of or larger than proton kinetic scales. An exact stationary solution is presented by revisiting previous results with a uniform-density shear flow, directed either parallel or perpendicular to a uniform magnetic field, and by adapting the solution to the hybrid Vlasov-Maxwell model. A quantitative characterization of the equilibrium distribution function is provided by studying both analytically and numerically the temperature anisotropy and gyrotropy and the heat flux. In both cases, in the shear region, the velocity distribution significantly departs from local thermodynamical equilibrium. A comparison between the time behavior of the usual "fluid-like" equilibrium shifted Maxwellian and the exact stationary solutions is carried out by means of numerical simulations of the hybrid Vlasov-Maxwell equations. These hybrid equilibria can be employed as an unperturbed states for numerous problems which involve sheared flows, such as the wave propagation in inhomogeneous background and the onset of the Kelvin-Helmholtz instability.

description: We study local electronic properties of graphene oxide (GO) and reduced graphene oxide (RGO) on metallic (Pt) and insulating (Si3N4) substrates in controlled humidity environment. We demonstrate that the supporting substrate plays a crucial role in interaction of these materials with water, with Pt making both GO and RGO insensitive to humidity variations and change in environment. On the other hand, in the case of Si3N4 substrate a significant difference between GO and RGO with respect to humidity variations is demonstrated, indicating complete water coverage at ~60% R.H for RGO and ~30% R.H. for GO. Irrespective of the substrate, both GO and RGO demonstrate relative independence of their electronic properties on the material thickness, with similar trends observed for 1, 2 and 3 layers when subject to humidity variations. This indicates a relatively minor role of material thickness in GO-based humidity sensors.

description: Introduction: Published literature suggests that task shifting is a very affordable way of providing health services in resource constrained settings. However, there is less empirical evidence on its effects on the mainstream tasks and workload of the cadres to whom the tasks are shifted. This thesis examines the consequences of delegating HIV testing and counselling services to Health Surveillance Assistants (HSAs) on their community work, workload and motivation in Malawi. Methods: Client records for Pentavalent, family planning and HTC for the period 2006-2010, when task shifting using HSAs just started, were collected from eight health facilities in Salima and Mangochi districts. Semi-structured interviews with 243 HSAs and in-depth interviews with 12 managers at national, district and health facility levels were also conducted to get their views and experiences with task shifting. Quantitative data and qualitative data were analysed separately and then later triangulated to identify recurring patterns and areas of commonality and discrepancies. Key findings: In 2007 when HTC task shifting using HSAs started, PHC and HTC services scaled-up especially at the facility and district levels. However, at the individual HSA level, PHC delivery declined arising mainly from high workload, difficulties with managing competing tasks and other health system challenges. Even though successful in service scale-up, the arrangement did not satisfy most recommendations by WHO on implementing task shifting and the success could be attributed to historical task shifting in the Malawi health sector. The HSAs reported facing challenges, common to the Malawi health sector, including long distances to catchment areas; large catchment populations, mobility problems, high workload, difficulties to schedule activities and unclear career path and low remuneration. Conclusions: Task shifting led to service scale-up in 2007 but mainly at the district and facility levels which may not have translated into similar improved PHC provision at the HSA catchment area level as the HSAs were grappling with many challenges which were affecting their motivation and job satisfaction. To sustain the success with task shifting, it may be prudent to provide more support to the HSAs, increase their numbers and consider some form of incentives.

description: Possibly the only unambiguous verification that gamma-ray bursts (GRBs) are at cosmological distances would be the observation of multiple images of a gravitationally lensed burst. Each images would arrive at a different time, but exhibit identical light curves. We improve upon previous calculations of GRB lensing by using revised cosmological burst models based upon better knowledge of burst spectra, and we consider several sets of cosmological parameters. Only lensing by the known population of galaxies is considered, and we compute the lensing rate and amplification bias using three different lens models. Assuming that 800 bursts per year are above the detection threshold of the BATSE experiment on the Compton Gamma-Ray Observatory, we predict one lensing event every 1.5--25 years, with a median time delay between images of about 7 days. However, BATSE has an instrumental efficiency of about 12\% for detecting double bursts, decreasing the detection rate to fewer than one per century for some cosmological parameters. This inefficiency can be overcome partially if cases of quadruple imaging by elliptical potentials are common, but simulations show that lensing by elliptical potentials enhances the detection rate by only about 20\%. We conclude that it is unlikely that the BATSE experiment will detect a lensed burst, but that a future experiment, which is either much more sensitive or has a much more efficient duty cycle, could.

Brown-Teitelboim Instantons and the First Law of Thermodynamics of (Anti) de Sitter Space

description: We study the instantons (or bounces) in the Brown-Teitelboim (BT) mechanism of relaxation of cosmological constant which is a cosmological version of the Schwinger mechanism. The BT mechanism is a false vacuum decay of (A)dS$_{d+1}$ (and $R^{1, d}$) spaces via spontaneous nucleations of spherical $(d-1)$-branes and thus ostensibly has bearings on (A)dS$_{d+1}$/CFT$_d$ holography. In this paper we focus on the four-dimensional case, although the higher or lower-dimensional generalization is straightforward. As is the case with pair productions near black hole and de Sitter horizons, we show that the BT instanton action for a membrane nucleation encodes the first law of thermodynamics of (Anti) de Sitter space. In particular, the membrane instanton precisely accounts for the change of entropy of (A)dS space before and after nucleation, in good accordance with AdS$_{d+1}$/CFT$_d$ in which the $(d-1)$-branes make up all degrees of freedom of AdS$_{d+1}$ space. In light of this lesser-known perspective presented here we also make remarks on (1) (A)dS/CFT and (2) complexity. For the complexity we observe that the Lorentzian bounce action may have close connection to complexity.

The Role of Glycosylated Alpha-1 Antitrypsin in Resolution of Inflammation

description: Alpha-1 antitrypsin (AAT) is a 52 kDa, glycoprotein, whose main function is to inhibit neutrophil elastase (NE), maintaining the protease/anti-protease balance in the lung. However, this acute phase protein has been shown to possess immuno-regulatory properties, independent of this anti-protease activity. The glycans of AAT alter during community acquired pneumonia, due to increased levels of sialic acid (rpAAT). The aim of this study was to determine the cause and consequence of rpAAT production. The cause of rpAAT production was investigated in hepatocytes, and it was observed that interleukin (IL-) 6 induced increased protein expression of beta-galactoside alpha-2,6-sialyltransferase 1 (ST6GAL1), an enzyme responsible for the addition of sialic acid. Additionally, it was discovered that IL-10 causes a decrease in the protein expression of ST6GAL1. As rpAAT is produced during resolution of inflammation, the consequence of rpAAT production was investigated. It was uncovered that rpAAT binds a higher level of chemokines than the less sialylated AAT, as IL-8 and neutrophil activating peptide 2 (NAP-2), were bound more strongly to rpAAT. These are drivers of neutrophil activation and migration. A key finding of this study was that by binding these chemokines, rpAAT decreases the ability of IL-8 and NAP-2 to engage with the CXCR receptors on the neutrophil membrane. Furthermore, rpAAT reduced both neutrophil migration and degranulation in response to IL-8 and NAP-2 to a greater extent than less sialylated AAT. However, rpAAT can be overwhelmed in excessive levels of inflammation. rpAAT is produced during resolution of acute inflammation indicating that rpAAT is produced to aid resolution. Our findings add to our understanding of AAT, revealing a natural way by which the body acts to control excessive inflammation. This knowledge has implications for the use of AAT as a therapy to treat conditions dominated by neutrophil driven inflammation.

description: Vertical stacks of two-dimensional (2D) materials, separated by the van der Waals gap and held together by the van der Waals forces, are immensely promising for a plethora of nanotechnological applications. Charge control in these stacks may be modeled using either a simple electrostatics approach or a detailed atomistic one. In this paper, we compare these approaches for a gated 2D transition metal dichalcogenide bilayer and show that recently reported electrostatics-based models of this system give large errors in band energy compared to atomistic (Density Functional Theory) simulations. These errors are due to the tails of the ionic potentials that reduce the electrical-equivalent van der Waals gap between the 2D layers, and can be corrected by using the reduced gap in the electrostatic model. For a physical van der Waals gap (defined as the chalcogen to chalcogen distance) of 3 $\mathrmÅ$ in a 2D bilayer, the electrical-equivalent gap is less than 1 $\mathrmÅ$. For the example of band-to-band tunneling based ultra low-power transistors, this is seen to lead to errors of several hundred millivolts and more in the threshold voltage estimated from electrostatics.

description: Approximately 80% of breast cancers overexpress the estrogen receptor α (ERα) and depend on this key transcriptional regulator for growth. The discovery of novel mechanisms controlling ERα function represent major advances in our understanding of breast cancer progression and potentially offer new therapeutic opportunities. Here, we investigated the role of deubiquitinating enzymes (DUBs), which remove ubiquitin moieties from proteins, in regulating ERα activity in breast cancer. To identify DUBs involved in ERα transcriptional activity, an RNAi loss-of-function screen using a library of shRNA vectors targeting all 108 known or putative human DUB genes was performed. Suppression of the BRCA-associated DUB, USP11 was found to downregulate ERα transcriptional activity in ZR-75-1 cells and was the sole focus of this study. Knockdown of USP11 in ZR-75-1 cells decreased ERα transcriptional activity and mRNA expression of ERα target genes. Furthermore, estradiol (E2) stimulation of these cells resulted in upregulation of USP11 in the nucleus and the formation of USP11 nuclear foci. IHC staining of a breast cancer tissue microarray (103 ER+ patients) and subsequent Kaplan-Meier analysis of this cohort revealed a significant association between high USP11 expression and poor overall (p=0.030) and breast cancer-specific survival (p=0.041). In silico analysis of publicly available breast cancer gene expression datasets further supported this observation. Interestingly, USP11 expression was upregulated in LCC1 cells, an isogenic, estrogen-independent model derived from MCF-7 cells. Knockdown of USP11 in LCC1 cells decreased the expression of multiple ERα target genes and cell cycle-associated genes, as determined by RNA sequencing (RNA-seq). Finally, knockdown of USP11 in ZR-75-1 cells induced significant changes in the proteome, as determined by liquid chromatography mass spectrometry (LC-MS). This study, for the first time, determines a role for USP11 in ERα transcriptional activity. With further support, USP11 may represent a novel biomarker and therapeutic target in ERα-positive (ERα+) breast cancer.
