description: For a cosmological Randall-Sundrum braneworld with anisotropy, i.e., of Bianchi type, the modified Einstein equations on the brane include components of the five-dimensional Weyl tensor for which there are no evolution equations on the brane. If the bulk field equations are not solved, this Weyl term remains unknown, and many previous studies have simply prescribed it ad hoc. We construct a family of Bianchi braneworlds with anisotropy by solving the five-dimensional field equations in the bulk. We analyze the cosmological dynamics on the brane, including the Weyl term, and shed light on the relation between anisotropy on the brane and Weyl curvature in the bulk. In these models, it is not possible to achieve geometric anisotropy for a perfect fluid or scalar field -- the junction conditions require anisotropic stress on the brane. But the solutions can isotropize and approach a Friedmann brane in an anti-de Sitter bulk.

description: Rapid DNA template preparation directly from a single rice (Oryza sativa) grain or rice flour of its equivalent weight was developed for loop-mediated isothermal amplification (LAMP). LAMP efficiency using DNA extract obtained from consecutive addition of alkaline lysis reagent (25 mM NaOH, 0.2 mM EDTA) and neutralizing reagent (40 mM Tris–HCl [pH 5]) was comparable to that using an equivalent amount of purified DNA as template. The stability of the prepared DNA extract was confirmed for up to six-day storage at room temperature. Without using any special laboratory devices, the developed method enabled a rapid, simple, and low-cost DNA template preparation method for reliable LAMP testing to detect rice genes. A novel improved LAMP method for a single rice grain or rice flour from DNA extraction to visual detection of amplicon without laborious DNA purification and special laboratory devises.

description: Biomedical Named Entity Recognition (BioNER) is a crucial step for analyzing Biomedical texts, which aims at extracting biomedical named entities from a given text. Different supervised machine learning algorithms have been applied for BioNER by various researchers. The main requirement of these approaches is an annotated dataset used for learning the parameters of machine learning algorithms. Segment Representation (SR) models comprise of different tag sets used for representing the annotated data, such as IOB2, IOE2 and IOBES. In this paper, we propose an extension of IOBES model to improve the performance of BioNER. The proposed SR model, FROBES, improves the representation of multi-word entities. We used Bidirectional Long Short-Term Memory (BiLSTM) network; an instance of Recurrent Neural Networks (RNN), to design a baseline system for BioNER and evaluated the new SR model on two datasets, i2b2/VA 2010 challenge dataset and JNLPBA 2004 shared task dataset. The proposed SR model outperforms other models for multi-word entities with length greater than two. Further, the outputs of different SR models have been combined using majority voting ensemble method which outperforms the baseline models performance.

How Spectral Shapes of Magnetic Energy and Magnetic Helicity Influence their Respective Decay Time Scales

description: It is shown that in magnetohydrodynamics, the shapes of the magnetic energy and magnetic helicity spectra can influence whether the magnetic helicity resistive dissipation time scale is longer, equal to, or shorter than that of magnetic energy. The calculations highlight that magnetic helicity need not always dissipate significantly more slowly than magnetic energy. While this may be implicitly understood in detailed studies of magnetic helicity in plasma devices, it is not sufficiently emphasized in elementary discussions comparing magnetic helicity vs. magnetic energy evolution. Measuring magnetic energy and helicity decay times may provide a posteriori insight into the initial spectra.

Using schematic models to understand the microscopic basis for inverted solubility in $γ$D-crystallin

description: Inverted solubility--a crystal melting upon cooling--is observed in a handful of proteins, such as carbomonoxy hemoglobin and $γ$D-crystallin. In human $γ$D-crystallin, the phenomenon is associated with the mutation of the 23$^\mathrm{rd}$ residue, a proline, to a threonine, serine or valine. One proposed microscopic mechanism for this effect entails an increase in hydrophobicity upon mutagenesis. Recent crystal structures of a double mutant that includes the P23T mutation allows for a more careful investigation of this proposal. Here, we first measure the surface hydrophobicity of various mutant structures of this protein and determine that it does not discernibly increase upon the mutating the 23$^\mathrm{rd}$ residue. We then investigate the solubility inversion regime with a schematic patchy particle model that includes one of three models for temperature-dependent patch energies: two of the hydrophobic effect, and a more generic description. We conclude that while solubility inversion due to the hydrophobic effect may be possible, microscopic evidence to support it in $γ$D-crystallin is weak. More generally, we find that solubility inversion requires a fine balance between patch strengths and the temperature-dependent contribution, which may explain why inverted solubility is not commonly observed in proteins. In any event, we also find that the temperature-dependent interaction has only a negligible impact on the critical properties of the $γ$D-crystallin, in line with previous experimental observations.

description: Supernova remnants (SNRs) have a variety of overall morphology as well as rich structures over a wide range of scales. Quantitative study of these structures can potentially reveal fluctuations of density and magnetic field originating from the interaction with ambient medium and turbulence in the expanding ejecta. We have used $1.5$GHz (L band) and $5$GHz (C band) VLA data to estimate the angular power spectrum $C_{\ell}$ of the synchrotron emission fluctuations of the Kepler SNR. This is done using the novel, visibility based, Tapered Gridded Estimator of $C_{\ell}$. We have found that, for $\ell = (1.9 - 6.9) \times 10^{4}$, the power spectrum is a broken power law with a break at $\ell = 3.3 \times 10^{4}$, and power law index of $-2.84\pm 0.07$ and $-4.39\pm 0.04$ before and after the break respectively. The slope $-2.84$ is consistent with 2D Kolmogorov turbulence and earlier measurements for the Tycho SNR. We interpret the break to be related to the shell thickness of the SNR ($0.35 $ pc) which approximately matches $\ell = 3.3 \times 10^{4}$ (i.e., $0.48$ pc). However, for $\ell > 6.9 \times 10^{4}$, the estimated $C_{\ell}$ of L band is likely to have dominant contribution from the foregrounds while for C band the power law slope $-3.07\pm 0.02$ is roughly consistent with $3$D Kolmogorov turbulence like that observed at large $\ell$ for Cas A and Crab SNRs.

description: Introduction: Platinum-based chemotherapy is the current first-line standard therapy for unresectable malignant pleural mesothelioma (MPM). Recently, immune-checkpoint inhibitors (ICI) have been intensively investigated as treatment options for this disease. Nivolumab, an anti-programmed cell death (PD)-1 agent, was one of the first drugs used and is representative of available ICIs. Areas covered: This review discusses previous relevant reports and current ongoing trials of nivolumab. The efficacy and safety of nivolumab have been investigated mostly in second-line or later treatment settings as both monotherapy and in combination with other ICIs. Particularly, nivolumab monotherapy yielded promising efficacy with an objective response rate of 29% and median overall survival of 17.3 months in salvage settings in the single-arm, Japanese phase 2 trial (MERIT). Notably, the study led to Japanese approval of nivolumab for unresectable recurrent MPM. Several trials with monotherapy or cotherapy with nivolumab have commenced, including randomized trials of nivolumab monotherapy vs. placebo in the salvage setting, and cotherapy with nivolumab and ipilimumab vs. the platinum doublet in the frontline setting. Expert opinion: Nivolumab seems like a reasonable option for unresectable, relapsed MPM despite the lack of randomized trial data. Ongoing pivotal trials will confirm its efficacy.

description: We analyze safety problems of complex systems using the methods of mathematical statistics for testing the output variables of a code simulating the operation of the system under consideration when the input variables are uncertain. We have defined a black box model of the code and derived formulas to calculate the number of runs needed for a given confidence level to achieve a preassigned measure of safety. In order to show the capabilities of different statistical methods, firstly we have investigated one output variable with unknown and known distribution functions. The general conclusion has been that the different methods do not bring about large differences in the number of runs needed to ensure a given level of safety. Analyzing the case of several statistically dependent output variables we have arrived at the conclusion that the testing of the variables separately may lead to false, safety related decisions with unforseen consequences. We have advised two methods: the sign test and the tolerance interval methods for testing more than one mutually dependent output variables.

description: EC53 is an embedded protostar with quasi-periodic emission in the near-IR and sub-mm. We use ALMA high-resolution observations of continuum and molecular line emission to describe the circumstellar environment of EC 53. The continuum image reveals a disk with a flux that suggests a mass of 0.075 Msun, much less than the estimated mass in the envelope, and an in-band spectral index that indicates grain growth to centimeter sizes. Molecular lines trace the outflow cavity walls, infalling and rotating envelope, and/or the Keplerian disk. The rotation profile of the C17O 3-2 line emission cannot isolate the Keplerian motion clearly although the lower limit of the protostellar mass can be calculated as 0.3 +- 0.1 Msun if the Keplerian motion is adopted. The weak CH3OH emission, which is anti-correlated with the HCO+ 4-3 line emission, indicates that the water snow line is more extended than what expected from the current luminosity, attesting to bygone outburst events. The extended snow line may persist for longer at the disk surface because the lower density increases the freeze-out timescale of methanol and water.

Determination of multiquantum vibrational transition moments in hydrogen iodide and their significance in its vibrational photochemistry.
Creators: name: Reiner, Robert Henry
Publisher: name: California Institute of Technology
Year: 1976
Subjects: Chemistry

description: Estimates of the band intensities of transitions between the ground and upper vibrational levels (1-9) were made for HI. Calculations were performed with both Morse and RKR oscillator wavefunctions, using various functional approximations for the dipole operator fitted to known experimental results. Absorption measurements using a multiple pass cell placed upper bounds on transition intensities, which were not inconsistent with the calculated values. (Band strengths for HI ΔV = 8,9 are
less than 5 x 10(-4) cm^(-2) atm(^1)).

The feasibility of using these multiquantum vibrational transitions to pump the reaction HI + HI*(v - 8,9) → H_2 + 2I is discussed.

description: In two recent papers we explored the modifications to primordial black hole physics when one moves to the simplest braneworld model, Randall--Sundrum type II. Both the evaporation law and the cosmological evolution of the population can be modified, and additionally accretion of energy from the background can be dominant over evaporation at high energies. In this paper we present a detailed study of how this impacts upon various astrophysical constraints, analyzing constraints from the present density, from the present high-energy photon background radiation, from distortion of the microwave background spectrum, and from processes affecting light element abundances both during and after nucleosynthesis. Typically, the constraints on the formation rate of primordial black holes weaken as compared to the standard cosmology if black hole accretion is unimportant at high energies, but can be strengthened in the case of efficient accretion.

description: Immobilization of enzymes from different sources on various supports in designed systems increases enzymes’ stability by protecting the active site of it from undesired effect of reaction environment. Also, immobilization decreases the cost of separation and facilities the reuse of the enzymes. Therefore, the design of new immobilization enzyme preparations has been an inevitable area of modern biotechnology. Herein, Rhizomucor miehei lipase (RML) was immobilized on montmorillonite K-10 (MMT-RML) by adsorption and in polyvinyl alcohol (PVA-RML) by entrapment to obtain a more stable and active lipase preparation. The free and immobilized lipase preparations were characterized for p-nitrophenyl palmitate hydrolysis. The apparent Michaelis–Menten (Kmapp) constant was almost the same for the free RML and PVA-RML, whereas the corresponding value was 17.7-fold lower for MMT-RML. PVA-RML and MMT-RML have shown a 1.1 and 23.8 folds higher catalytic efficiency, respectively, than that of the free RML. The half-lives of PVA-RML and MMT-RML were found to be 7.4 and 3.4 times longer than the free RML at 35 °C, respectively. PVA-RML and MMT-RML maintained 65% and 87% of their initial activities after four reuses. These results showed that the catalytic performance of RML has improved significantly by immobilization.

A matching of the solution to a solution of the related one-dimensional problem leads to relation between the one-dimensional and three-dimensional scattering parameters. The scattering amplitude and bound states for the confined system demonstrate differences from the related free and one-dimensional systems.

description: Specific neuropeptides regulate in arthropods the shedding of the old cuticle (ecdysis) followed by maturation of the new cuticle. In Drosophila melanogaster, the last ecdysis occurs at eclosion from the pupal case, with a post-eclosion behavioural sequence that leads to wing extension, cuticle stretching and tanning. These events are highly stereotyped and are controlled by a subset of crustacean cardioactive peptide (CCAP) neurons through the expression of the neuropeptide Bursicon (Burs). We have studied the role of the transcription factor Odd-paired (Opa) during the post-eclosion period. We report that opa is expressed in the CCAP neurons of the central nervous system during various steps of the ecdysis process and in peripheral CCAP neurons innerving the larval muscles involved in adult ecdysis. We show that its downregulation alters Burs expression in the CCAP neurons. Ectopic expression of Opa, or the vertebrate homologve Zic2, in the CCAP neurons also affects Burs expression, indicating an evolutionary functional conservation. Finally, our results show that, independently of its role in Burs regulation, Opa prevents death of CCAP neurons during larval development.

description: Game-theoretic analysis is a well-established part of the toolkit of economic analysis. In crucial respects, however, game theory has failed to deliver on its original promise of generating sharp predictions of behavior in situations where neoclassical microeconomics has little to say. Experience has shown that in most situations, it is possible to tell a game-theoretic story to fit almost any possible outcome. We argue that, in general, any individually rational outcome of an economic interaction may be supported as the Nash equilibrium of an appropriately chosen game, and that a wide range of these outcomes will have an economically reasonable interpretation. We consider possible attempts to salvage the original objectives of the game-theoretic research program. In at least some cases, information on institutional structures and observations of interactions between agents can be used to limit the set of strategies that may be considered reasonable

description: We present a design for high energy density laboratory experiments studying the interaction of hypersonic shocks with a large number of inhomogeneities. These ``clumpy'' flows are relevant to a wide variety of astrophysical environments including the evolution of molecular clouds, outflows from young stars, Planetary Nebulae and Active Galactic Nuclei. The experiment consists of a strong shock (driven by a pulsed power machine or a high intensity laser) impinging on a region of randomly placed plastic rods. We discuss the goals of the specific design and how they are met by specific choices of target components. An adaptive mesh refinement hydrodynamic code is used to analyze the design and establish a predictive baseline for the experiments. The simulations confirm the effectiveness of the design in terms of articulating the differences between shocks propagating through smooth and clumpy environments. In particular, we find significant differences between the shock propagation speeds in a clumpy medium compared to a smooth one with the same average density. The simulation results are of general interest for foams in both inertial confinement fusion and laboratory astrophysics studies. Our results highlight the danger of using average properties of inhomogeneous astrophysical environments when comparing timescales for critical processes such as shock crossing and gravitational collapse times.

description: We show how to derive the equations of light propagation in the gravitational field of uniformly moving mass monopoles without formulating and integrating the differential equations of light propagation in that field. The well-known equations of light propagation in the gravitational field of a motionless mass monopole are combined with a suitable Lorentz transformation. The possibility to generalize this technique for the more complicated case of uniformly moving body of arbitrary multipole structure is discussed.

description: Insurance contracts are frequently modelled as principal--agent relationships. Although it is commonly assumed that the principal, in this case the insurer, has complete freedom to design the contract, the problem formulation in much of the principal--agent literature presumes that the contract is constrained-Pareto-efficient. In the present paper, we consider the implications of a richer specification of the choices available to clients. In particular, we consider the entire spectrum of possible power differentials in the contracting relationship between insurers and clients. Our central result is that the agent can exploit information asymmetries to offset the bargaining power of the insurer, but that this process is socially costly.

Spontaneous symmetry breaking in a classical particle

Subjects: subject: High Energy Physics - Theory (hep-th)

description: Due to the fact that only matter fields have phase, frequently is believed that the gauge principle can induce gauge fields only in quantum systems. But this is not necessary. This paper, of pedagogical scope, presents a classical system constituted by a particle in a classical potential, which is used as a model to illustrate the gauge principle and the spontaneous symmetry breaking. Those concepts appear in the study of second order phase transitions. Ferroelectricity, ferromagnetism, superconductivity, plasmons in a free electron gas, and the mass of vector bosons in the gauge field Yang-Mills theories, are some of the phenomena in which these transitions occur.

A correlation of the cosmic microwave sky with large scale structure
Creators: name: Boughn, Stephen

Year: 2003
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: We cross correlate the large-scale cosmic microwave background (CMB) sky measured by WMAP with two probes of large-scale structure at z ~ 1. The hard X-ray background, measured by the HEAO-1 satellite, is positively correlated with the WMAP data at the 2.5-3.0 sigma level. The number counts of radio galaxies in the NVSS survey are also correlated at a slightly weaker level (2.-2.5 sigma). These correlations appear to arise from both hemispheres on the sky and are resilient to changes in the levels of masking of the Galaxy and point sources, suggesting that foregrounds are not responsible for the signal. The implication is that some of the observed CMB fluctuations arise at low redshifts. The level of the correlations is consistent with that expected for the cosmological constant (Omega_Lambda = 0.72) concordance model resulting from the integrated Sachs-Wolfe effect. Thus, we may be observing dark energy's effect on the growth of structure.

description: The out-of-time-ordered correlators (OTOC) have been established as a fundamental concept for quantifying quantum information scrambling and diagnosing quantum chaotic behavior. Recently, it was theoretically proposed that the OTOC can be used as an order parameter to dynamically detect both equilibrium quantum phase transitions (EQPTs) and dynamical quantum phase transitions (DQPTs) in one-dimensional many-body systems. Here we report the first experimental observation of EQPTs and DQPTs in a quantum spin chain via quench dynamics of OTOC on a nuclear magnetic resonance quantum simulator. We observe that the quench dynamics of both the order parameter and the two-body correlation function cannot detect the DQPTs, but the OTOC can unambiguously detect the DQPTs. Moreover, we demonstrate that the long-time average value of the OTOC in quantum quench signals the equilibrium quantum critical point and ordered quantum phases, thus one can measure the EQPTs from the non-equilibrium quantum quench dynamics. Our experiment paves a way for experimentally investigating DQPTs through OTOCs and for studying the EQPTs through the non-equilibrium quantum quench dynamics with quantum simulators.

description: This paper investigates the optimality of sharp incentives in contracts where output prices are set at the time of contracting but are random in nature. It shows that when prices are specified with error, schemes involving sharp incentives might result in substantial deviations from first-best output levels. The randomness of prices creates arbitrage opportunities that are exploited by agents producing phenomena such as "cost-shifting". Both linear and piece-wise linear contracts are shown to be subject to the possibility of arbitrage. The paper then demonstrates that incentive schemes that are arbitrage-proof exhibit "diffuse" incentives.

description: P-Stars are a new class of compact stars made of up and down quarks in beta-equilibrium with electrons in an Abelian chromomagnetic condensate. We show that P-Stars are able to account for compact stars with R < 6 Km, as well as stars with radius comparable with canonical Neutron Stars. We find that cooling curves of P-Stars compare rather well with observational data. We suggest that P-Matter produced at the primordial deconfinement transition is a viable candidate for baryonic Cold Dark Matter. Finally, we show that P-Stars are able to overcome the gravitational collapse even for mass much greater than 10^6 Solar Mass.
