description: We present a simple result for the action density of the SU(n) charge one periodic instantons - or calorons - with arbitrary non-trivial Polyakov loop P_oo at spatial infinity. It is shown explicitly that there are n lumps inside the caloron, each of which represents a BPS monopole, their masses being related to the eigenvalues of P_oo. A suitable combination of the ADHM construction and the Nahm transformation is used to obtain this result.

description: A quantum simulator is proposed for nucleation and growth dynamics using an out-of equilibrium optical lattice. We calculate the density of neutral atoms in the lattice and we establish the connection with the Kolmogorov-Mehl-Johnson-Avrami model. Here we show that a Avrami equation can describe most of the evolution in time of the population growth in the lattice, coherence between neutral atoms leads a complex growth rate.

description: We use new studies of the cosmic evolution of star-forming galaxies to estimate the production rate of ionizing photons from hot, massive stars at low and intermediate redshifts. The luminosity function of blue galaxies in the Canada-France Redshift Survey shows appreciable evolution in the redshift interval z=0-1.3, and generates a background intensity at 1 ryd of J_L~ 1.3 x 10^{-21} f_{esc} ergs cm^{-2} s^{-1} Hz^{-1} sr^{-1} at z~0.5, where f_esc is the unknown fraction of stellar Lyman-continuum photons which can escape into the intergalactic space, and we have assumed that the absorption is picket fence-type. We argue that recent upper limits on the H-alpha surface brightness of nearby intergalactic clouds constrain this fraction to be ~ 6%. We show that, in the general framework of a diffuse background dominated by QSOs and/or star-forming galaxies, the cosmological baryon density associated with photoionized, optically thin gas decreases rapidly with cosmic time. The results of a recent Hubble Space Telescope survey of OVI absorption lines in QSO spectra suggest that most of this evolution may be due to the bulk heating and collisional ionization of the intergalactic medium by supernova events in young galaxy halos.

description: We study the cosmological evolution of string/M moduli fields T. We use T-duality to fix the potential and show that the superpotential W is a function of the duality invariant function j(T) only. If W is given as a finite polynomial of j then the moduli fields {\it do not} give an accelerating universe, i.e. they {\it cannot} be used as quintessence. Furthermore, at T >>1 the potential is given by a double exponential potential V \simeq e^{-a e^{\sqrt{2} T}} leading to a fast decaying behaviour at large times. For moduli potentials with a finite v.e.v. of T the energy density redshift is model dependent but if T has a finite mass, m < \infty, then the moduli energy density redshifts faster or equal to matter. Only if the moduli mass is infinite can the moduli energy density dominate the universe independently of the initial conditions.

description: We give a proof of the equivalence of the electric-magnetic duality on one side and helicity conservation of the tree level amplitudes on the other side within general models of nonlinear electrodynamics. Using modified Feynman rules derived from generalized normal ordered Lagrangian we discuss the interrelation of the above two properties of the theory also at higher loops. As an illustration we present two explicit examples, namely we find the generalized normal ordered Lagrangian for the Born-Infeld theory and derive a semi-closed expression for the Lagrangian of the Bossard-Nicolai model (in terms of the weak field expansion with explicitly known coefficients) from its normal ordered form.

description: We present the first observational evidence for a collimated jet in a cataclysmic variable system; the recurrent nova T Pyxidis. Optical spectra show bipolar components of H$α$ with velocities $\sim 1400 km/s$, very similar to those observed in the supersoft X-ray sources and in SS 433. We argue that a key ingredient of the formation of jets in the supersoft X-ray sources and T Pyx (in addition to an accretion disk threaded by a vertical magnetic field), is the presence of nuclear burning on the surface of the white dwarf.

description: Dampier Strait MPA is one of the largest MPAs in the Raja Ampat MPA network. In 2016, 14 sites were surveyed by a team from Conservation International (CI) and partners, including Raja Ampat UPTD, CoE UNIPA, and Satker BKKPN Kupang, from the 7th-8th and 15th-17th of March. The Dampier Strait MPA has been previously monitored in 2010 and 2014. In general, coral reef ecosystems are in healthy condition. Coral cover has remained relatively stable since monitoring began six years ago. Meanwhile, the biomass of key functional fish families and key fisheries families moderately increased over time. These conditions might have happened as an impact from the patrol systems carried out regularly by the Raja Ampat MPA Management Authority and its partners. In addition, Dampier Strait is known as one of the 'most crowded' tourism areas within Raja Ampat, which contributed to prevent the illegal fishing practices in the region.

description: We study scalar particle decay during the radiation and matter dominated epochs of a standard cosmological model. An adiabatic approximation is introduced that is valid for degrees of freedom with typical wavelengths much smaller than the particle horizon ($\propto$~Hubble radius) at a given time. We implement a non-perturbative method that includes the cosmological expansion and obtain a cosmological Fermi's Golden Rule that enables one to compute the decay law of a parent particle of mass $m_1$, along with the build up of the population of daughter particles of mass $m_2$. The survival probability of the decaying particle is $P(t)=e^{-\widetildeΓ_k(t)\,t}$ with $\widetildeΓ_k(t)$ being an \emph{effective momentum and time dependent decay rate}. It features a transition time scale $t_{nr}$ between the relativistic and non-relativistic regimes and for $k \neq 0$ is always smaller than the analogous rate in Minkowski spacetime, as a consequence of (local) time dilation and the cosmological redshift. For $t \ll t_{nr}$ the decay law is a "stretched exponential" $P(t) = e^{-(t/t^*)^{3/2}}$, whereas for the non-relativistic stage with $t \gg t_{nr}$, we find $P(t) = e^{-Γ_0 t}\,(t/t_{nr})^{Γ_0\,t_{nr}/2}$. The Hubble time scale $\propto 1/H(t)$ introduces an energy uncertainty $ΔE \sim H(t)$ which relaxes the constraints of kinematic thresholds. This opens new decay channels into heavier particles for $2πE_k(t) H(t) \gg 4m^2_2-m^2_1$, with $E_k(t)$ the (local) comoving energy of the decaying particle. As the expansion proceeds this channel closes and the usual two particle thresholds restrict the decay kinematics.

description: Free volume theory (FVT) is a versatile and tractable framework to predict the phase behaviour of mixtures of platelets and non-adsorbing polymer chains in a common solvent. Within FVT, three principal reference phases for the hard platelets are considered: isotropic (I), nematic (N), and columnar (C). We derive analytical expressions that enable us to systematically trace the different types of phase coexistences revealed upon adding depletants and confirm the predictive power of FVT by testing the calculated diagrams against phase stability scenarios from computer simulation. A wide range of \textit{multi}-phase equilibria is revealed, involving two-phase isostructural transitions of all phase symmetries (INC) considered as well as the possible three-phase coexistences. Moreover, we identify the system parameters, relative disk shapes and colloid-polymer size ratios, at which four-phase equilibria are expected. These involve a remarkable coexistence of all three phase states commonly encountered in discotics including isostructural coexistences I$_1$-I$_2$-N-C, I-N$_1$-N$_2$-C, and I-N-C$_1$-C$_2$.

description: CeO2 materials have received wide attention given their oxidase-like activity without the need for an unstable oxide substrate in the catalytic process. Nevertheless, their application and mechanism in the catalytic oxidation of refractory organic pollutants needs further study. Herein, CeO2 hollow microspheres (HMS) with an intrinsic oxidase-like activity were synthesised via a template-free hydrothermal method and their effectiveness in degrading p-nitrophenol(p-NP) was investigated. HMS showed a maximum p-NP degradation rate of 76.5% at a CeO2 dosage of 40 mg, 2 h reactive time, at 30°C and pH of 4.8 when the concentration of p-NP was 20 mg L−1. The catalytic activity of CeO2 HMS also exhibited good thermal stability and reusability. These results provide strong evidence that CeO2 HMS can be utilised as an oxidase mimetic for the efficient catalytic degradation of refractory organic pollutants. A possible mechanism for the degradation of p-NP is also discussed.

description: We consider various contributions to the nonresonant decay $B^\pm\rightarrow π^+π^-π^\pm$, both of the long-distance and short-distance types with the former providing for most of the branching ratio, predicted to be $BR(B^\pm\rightarrow π^+π^-π^\pm) = (1.5 - 8.4 )\times 10^{-5}$. We also discuss an application to CP violation resulting from the interference of that nonresonant background (with $m(π^+π^-)\approx 3.4$ GeV) and $B^\pm\rightarrow χ_{c0} π^\pm$ followed by $χ_{c0}\rightarrow π^+π^-$. The resulting value of the partial rate asymmetry is $(0.40\sim 0.48)\mbox{sin}γ$, where $γ= \mbox{arg}(V_{ub}^*)$.

description: This article reassesses the discussion about bioethics and biorights over anencephalic babies’ abortion, and how significant is the moral controversial regarding women’s dignity and the right to health. Based on a deductive approach, arising from a critical comprehension of the reality, this study analyzes the mischaracterization of abortion as a crime by the Brazilian Federal Supreme Court, in order to compare such process with Ronald Dworkin’s work, Life’s Dominion, which follows a liberal line when compared to the conservative legislation regarding the subject. Arguments from both poles – “pro-life” and “pro-choice” groups – will be analyzed based on the philosophic perspective of Ronald Dworkin about the intrinsic value of human life. Due to the duality of political views, the efforts are neutralized when the question about what is the limit permitted of abortions is made, since both opinions share the idea that human life is inviolable.

description: We consider a class of extremal and non-extremal four-dimensional black-hole solutions occuring in toroidally compactified heterotic string theory, whose ten-dimensional interpretation involves a Kaluza-Klein monopole and a five-brane. We show that these four-dimensional solutions can be connected to extremal and non-extremal two-dimensional heterotic black-hole solutions through a change in the asymptotic behaviour of the harmonic functions associated with the Kaluza-Klein monopole and with the five-brane. This change in the asymptotic behaviour can be achieved by a sequence of S and T-S-T duality transformations in four dimensions. These transformations are implemented by performing a reduction on a two-torus with Lorentzian signature. We argue that the same mechanism can be applied to extremal and non-extremal black-hole solutions in the FHSV model.

description: We investigate the radiative heat transfer along a chain of nanoparticles using both a purely kinetic approach based on the solution of a Boltzmann transport equation and an exact method (Landauer's approach) based on fluctuational electrodynamics. We show that the kinetic theory generally fails to predict properly the heat flux transported along the chain both at close (near-field regime) and large separation (far-field regime) distances. We report a deviation of a factor two between the heat fluxes predicted by the two approaches in the diffusive regime of heat transport and we show that this difference becomes even greater than two orders of magnitude in the ballistic regime.

In this we present a quantitative model of GCR origin and acceleration based on the acceleration of a mixture of interstellar and/or circumstellar gas and dust by supernova remnant blast waves. We present results from a nonlinear shock model which includes (i) the direct acceleration of interstellar gas-phase ions, (ii) a simplified model for the direct acceleration of weakly charged dust grains to energies of order 100keV/amu simultaneously with the gas ions, (iii) frictional energy losses of the grains colliding with the gas, (iv) sputtering of ions of refractory elements from the accelerated grains and (v) the further shock acceleration of the sputtered ions to cosmic ray energies. The calculated GCR composition and spectra are in good agreement with observations.

description: The exact Wilson loop expression for the pure Yang-Mills U(N) theory on a sphere $S^2$ of radius $R$ exhibits, in the decompactification limit $R\to \infty$, the expected pure area exponentiation. This behaviour can be understood as due to the sum over all instanton sectors. If only the zero instanton sector is considered, in the decompactification limit one exactly recovers the sum of the perturbative series in which the light-cone gauge Yang-Mills propagator is prescribed according to Wu-Mandelstam-Leibbrandt. When instantons are disregarded, no pure area exponentiation occurs, the string tension is different and, in the large-N limit, confinement is lost.

description: Hypersaline wastewater has been widely used in industrial processes in some countries short of freshwater, but calcium ions in such wastewater should be removed due to the danger of limescale being produced. In this study, calcium ions in hypersaline (sodium chloride: 5%) wastewater was biomineralized into different carbonate minerals under the action of free and immobilized Virgibacillus dokdonensis WLR1 bacteria. The results show that the calcium ion precipitation rate was much higher under the conditions of immobilized bacteria (p < 0.01), and that there was a significant difference in the mineral phases, the diversity of protein secondary structures and morphologies, and chemical characteristics of the mineral surfaces between the free and the immobilized bacteria based on XRD, FTIR, SEM-EDS, and XPS analyses. TG, DTG, and DSC results show that with increasing calcium ion concentrations, the thermal stability of calcium carbonate under the conditions of free bacteria decreased due to the decline in crystallinity. The stable carbon isotope values (δ13CPDB) of calcium carbonate formed by free bacteria changed from −16.80‰ to −18.17‰; the much more negative δ13CPDB values suggest that the calcium carbonate minerals are biotic. From ultrathin slices analyzed by HRTEM-mapping-SAED, it was observed that calcite is formed inside the cell, thus also facilitating calcium ion removal. Research concerning intracellular calcite has rarely been reported. This study helps to further understand the mechanisms of biomineralization, and also provides an environmentally friendly method to remove calcium ions from hypersaline wastewater.

Life Cycle Assessment of Existing Structures and Retrofitting Tools

Publisher: name: Zenodo

description: This paper presents the results of a study of the environmental performance of two case study houses, one refurbished and one newly constructed. An analysis of the assembly, use, and end-of-life phases during 50 and 80-year life cycles was used to determine the environmental performance of retrofits and new construction. The environmental impact of each stage is modeled using raw information, LCA software and LCA database. In both case studies, the operational phase was found to be the largest source of environmental damage, followed by the assembly phase and the end-of-life phase. As the lifetime increases, the relative importance of the assembly and end-of-life phases decreases. It was found that the reconstructed dwellings studied outperformed new construction during the assembly and operational phases, while new construction performed better at the end-of-life phase.
Renormalization and Running of Quark Mass and Field in the Regularization Invariant and MS-bar Schemes at Three and Four Loops

description: We derive explicit transformation formulae relating the renormalized quark mass and field as defined in the MS-bar scheme with the corresponding quantities defined in any other scheme. By analytically computing the three-loop quark propagator in the high-energy limit (that is keeping only massless terms and terms of first order in the quark mass) we find the NNNLO conversion factors transforming the MS-bar quark mass and the renormalized quark field to those defined in a ``Regularization Invariant'' (RI) scheme which is more suitable for lattice QCD calculations. The NNNLO contribution in the mass conversion factor turns out to be large and comparable to the previous NNLO contribution at a scale of 2 GeV --- the typical normalization scale employed in lattice simulations. Thus, in order to get a precise prediction for the MS-bar masses of the light quarks from lattice calculations the latter should use a somewhat higher scale of around, say, 3 GeV where the (apparent) convergence of the perturbative series for the mass conversion factor is better. We also compute two more terms in the high-energy expansion of the MS-bar renormalized quark propagator. The result is then used to discuss the uncertainty caused by the use of the high energy limit in determining the MS-bar mass of the charmed quark. As a by-product of our calculations we determine the four-loop anomalous dimensions of the quark mass and field in the Regularization Invariant scheme. Finally, we discuss some physical reasons lying behind the striking absence of zeta(4) in these computed anomalous dimensions.

description: We discuss speculative disaster scenarios inspired by hypothetical new fundamental processes that might occur in high energy relativistic heavy ion collisions. We estimate the parameters relevant to black hole production; we find that they are absurdly small. We show that other accelerator and (especially) cosmic ray environments have already provided far more auspicious opportunities for transition to a new vacuum state, so that existing observations provide stringent bounds. We discuss in most detail the possibility of producing a dangerous strangelet. We argue that four separate requirements are necessary for this to occur: existence of large stable strangelets, metastability of intermediate size strangelets, negative charge for strangelets along the stability line, and production of intermediate size strangelets in the heavy ion environment. We discuss both theoretical and experimental reasons why each of these appears unlikely; in particular, we know of no plausible suggestion for why the third or especially the fourth might be true. Given minimal physical assumptions the continued existence of the Moon, in the form we know it, despite billions of years of cosmic ray exposure, provides powerful empirical evidence against the possibility of dangerous strangelet production.

description: In this study, the adsorption property of magnetic graphene oxide grafted 3.0 generations polymaleicamide dendrimer (GO/Fe3O4-g-G3.0) nanohybrids for Hg(II) in aqueous solution was investigated by batch experiments and magnetic separation technology. The results showed that Hg(II) ions were partially reduced to Hg(I) in the adsorption process, the solution pH value had a major impact on Hg(II) adsorption, and the higher temperature was beneficial to the adsorption of GO/Fe3O4-g-G3.0. The adsorption kinetic was well-fitted by the pseudo-second-order kinetic equation and the Langmuir adsorption isotherm model correlated well with adsorption equilibrium data.

description: In this work, laser pressure welding of dissimilar aluminium and copper was conducted at a high welding speed of 15 m min−1. One-micron intermetallic compounds (IMCs) layer with heterogeneous dual-phases (copper and γ-Al4Cu9 phases) laminates in the joint interface were observed by transmission electron microscopy. The results showed that the combination of two joining mechanisms led to improved mechanical property, namely the mechanical interlocking due to the curved interface and the metallurgical bonding by the presence of the thin IMCs layer with heterogeneous laminates. The tensile shear force and the shear strength of the joint reached 2055 N and 111.94 MPa, respectively. The present study provides a more efficient method to join dissimilar aluminium and copper.

Publisher: name: Zenodo
Year: 2021

description: This case study builds on previous research transforming the 1910Library of Congress Subject Headings (1910 LCSH) into a computation-ready dataset, compliant with linked data standards. The Archival Resource Key (ARK) system offers persistent identifiers for vocabularies and is becoming more widely adopted. We provide background and motivation for our work with the Nineteenth-Century Knowledge Project (NCKP), review our data sources, and detail the implementation of ARKs. Finally, we review the Helping Interdisciplinary Vocabulary Engineering (HIVE) system and preset the unified workflow, which involved contributions from information science and humanities scholars, as well as computer science and information systems researchers. The conclusion provides insight into planned future work.
Spin content of constituent quarks and one-spin asymmetries in inclusive processes

description: We consider mechanism for one-spin asymmetries observed in inclusive hadron production. The main role belongs to the orbital angular momentum of the quark-antiquark cloud in the internal structure of constituent quarks. We argue that the origin of the asymmetries in pion production is a result of retaining of this internal angular orbital momentum by the perturbative phase of QCD under transition from the non-perturbative phase. The non-perturbative hadron structure is based on the results of chiral quark models. PACS number(s): 11.30.Qc, 12.40.Pp, 13.75.Ni, 13.88.+e

description: This paper develops a novel and efficient algorithm for Bayesian inference in inverse Gamma stochastic volatility models. It is shown that by conditioning on auxiliary variables, it is possible to sample all the volatilities jointly directly from their posterior conditional density, using simple and easy to draw from distributions. Furthermore, this paper develops a generalized inverse gamma process with more flexible tails in the distribution of volatilities, which still allows for simple and efficient calculations. Using several macroeconomic and financial datasets, it is shown that the inverse gamma and generalized inverse gamma processes can greatly outperform the commonly used log normal volatility processes with Student’s t errors or jumps in the mean equation.

description: Resistive-switching memories are alternative to Si-based ones, which face scaling and high power consumption issues. Tetrahedral amorphous carbon (ta-C) shows reversible, non-volatile resistive switching. Here we report polarity independent ta-C resistive memory devices with graphene-based electrodes. Our devices show ON/OFF resistance ratios$\sim$4x$10^5$, ten times higher than with metal electrodes, with no increase in switching power, and low power density$\sim$14$μ$W/$μ$m$^2$. We attribute this to a suppressed tunneling current due to the low density of states of graphene near the Dirac point, consistent with the current-voltage characteristics derived from a quantum point contact model. Our devices also have multiple resistive states. This allows storing more than one bit per cell. This can be exploited in a range of signal processing/computing-type operations, such as implementing logic, providing synaptic and neuron-like mimics, and performing analogue signal processing in non-von-Neumann architectures

Hydrodynamic transport functions from quantum kinetic theory

description: Starting from the quantum kinetic field theory [E. Calzetta and B. L. Hu, Phys. Rev. D37, 2878 (1988)] constructed from the closed-time-path (CTP), two-particle-irreducible (2PI) effective action we show how to compute from first principles the shear and bulk viscosity functions in the hydrodynamic-thermodynamic regime. For a real scalar field with $λΦ^{4}$ self-interaction we need to include 4 loop graphs in the equation of motion. This work provides a microscopic field-theoretical basis to the ``effective kinetic theory'' proposed by Jeon and Yaffe [S. Jeon and L. G. Yaffe, Phys. Rev. D53, 5799 (1996)], while our result for the bulk viscosity reproduces their expression derived from linear response theory and the imaginary-time formalism of thermal field theory. Though unavoidably involved in calculations of this sort, we feel that the approach using fundamental quantum kinetic field theory is conceptually clearer and methodically simpler than the effective kinetic theory approach, as the success of the latter requires clever rendition of diagrammatic resummations which is neither straightforward nor failsafe. Moreover, the method based on the CTP-2PI effective action illustrated here for a scalar field can be formulated entirely in terms of functional integral quantization, which makes it an appealing method for a first-principles calculation of transport functions of a thermal non-abelian gauge theory, e.g., QCD quark-gluon plasma produced from heavy ion collisions.

description: Evidence shows good tolerability in patients for subcutaneous injection volumes up to 3 mL. We investigated efficacy, pharmacokinetics, and tolerability of secukinumab 300 mg/2 mL pre-filled syringe (PFS) in patients with moderate to severe plaque psoriasis. ALLURE was a 52-week, multicenter, randomized (1:1:1), double-blind, placebo-controlled, parallel-group study. Co-primary endpoints were secukinumab Psoriasis Area Severity Index (PASI) 75 and Investigator’s Global Assessment modified 2011 0/1 (IGA mod 2011 0 or 1) responses at week 12 versus placebo. Other endpoints included the Self-Injection Assessment Questionnaire (SIAQ), and the ability to follow the instructions for use (IFU). Overall, 214 patients were randomized. The secukinumab 300 mg/2 mL PFS showed superiority over placebo for both PASI 75 (88.9% versus 1.7%; p<.0001) and IGA mod 2011 0 or 1 (76.4% versus 1.4%; p<.0001) responses at week 12. All secondary efficacy endpoints were met. The SIAQ scores were similar across groups and improved similarly over 12 weeks. All patients completed critical steps in the IFU at week 1. The secukinumab 300 mg/2 mL PFS groups showed superiority versus placebo, and it was a safe, effective, and convenient option for patients with psoriasis. NCT02748863.
Highly Compressible MHD Turbulence and Gravitational Collapse

description: We investigate the properties of highly compressible turbulence and its ability to produce self-gravitating structures. The compressibility is parameterized by an effective polytropic exponent gama-eff. In the limit of small gama-eff, the density jump at shocks is shown to be of the order of e^{M^2}, and the production of vorticity by the nonlinear terms appears to be negligible. In the presence of self-gravity, we suggest that turbulence can produce bound structures for gama-eff < 2(1-1/n), where 'n' is the typical dimensionality of the turbulent compressions. We show, by means of numerical simulations, that, for sufficiently small gama-eff, small-scale turbulent density fluctuations eventually collapse even though the medium is globally stable. This result is preserved in the presence of a magnetic field for supercritical mass-to-flux ratios.

Cosmological constant vs. quintessence

description: There is some evidence that the Universe is presently undergoing accelerating expansion. This has restored some credit to the scenarios with a non-vanishing cosmological constant. From the point of view of a theory of fundamental interactions, one may argue that a dynamical component with negative pressure is easier to achieve. As an illustration, the quintessence scenario is described and its shortcomings are discussed in connection with the nagging ``cosmological constant problem''.
