description: We present ALMA Band 7 polarisation observations of the OMC-1 region of the Orion molecular cloud. We find that the polarisation pattern observed in the region is likely to have been significantly altered by the radiation field of the $>10^{4}$ L$_{\odot}$ high-mass protostar Orion Source I. In the protostar's optically thick disc, polarisation is likely to arise from dust self-scattering. In material to the south of Source I - previously identified as a region of 'anomalous' polarisation emission - we observe a polarisation geometry concentric around Source I. We demonstrate that Source I's extreme luminosity may be sufficient to make the radiative precession timescale shorter than the Larmor timescale for moderately large grains ($> 0.005-0.1\,μ$m), causing them to precess around the radiation anisotropy vector (k-RATs) rather than the magnetic field direction (B-RATs). This requires relatively unobscured emission from Source I, supporting the hypothesis that emission in this region arises from the cavity wall of the Source I outflow. This is one of the first times that evidence for k-RAT alignment has been found outside of a protostellar disc or AGB star envelope. Alternatively, the grains may remain aligned by B-RATs and trace gas infall onto the Main Ridge. Elsewhere, we largely find the magnetic field geometry to be radial around the BN/KL explosion centre, consistent with previous observations. However, in the Main Ridge, the magnetic field geometry appears to remain consistent with the larger-scale magnetic field, perhaps indicative of the ability of the dense Ridge to resist disruption by the BN/KL explosion.

description: Graphene's distinctive electronic properties -- linear energy bands, zero-energy bandgap and tunable carrier density -- underscore its versatility. Understanding its responses in equilibrium and photoexcited conditions is key to unlocking its full potential. This research, employing optical pump - terahertz probe spectroscopy, uncovers disparities between charge-neutral and doped graphene responses in equilibrium conditions. A novel model is formulated to elucidate these deviations. Additionally, when selectively photoexcited by near-infrared pulses, graphene displays remarkably extended photodynamic responses attributed to interplaying cooling mechanisms. This work deepens our grasp of graphene's behaviour, which is vital for harnessing its potential, and underscores its relevance in diverse technological realms.

description: Primordial black holes (PBHs) can constitute the predominant fraction of dark matter (DM) if PBHs reside in the currently unconstrained "sublunar" mass range. PBHs originating from scalar perturbations generated during inflation can naturally appear with a broad spectrum in a class of models. The resulting stochastic gravitational wave (GW) background generated from such PBH production can account for the recently reported North American Nanohertz Observatory for Gravitational Waves (NANOGrav) pulsar timing array data signal, and will be testable in future GW observations by interferometer-type experiments such as Laser Interferometer Space Antenna (LISA). We show that the broad mass function of such PBH DM is already being probed by Subaru Hyper Suprime-Cam (HSC) microlensing data and is consistent with a detected candidate event. Upcoming observations of HSC will be able to provide an independent definitive test of the stochastic GW signals originating from such PBH DM production scenarios.

description: Minor planets 887 Alinda and 2062 Aten are typical near Earth asteroids (NEA). Our previous researches show their possible origin in catastrophic collision near Earth orbit. It is determine the target of present research -- to investigate interactions between these objects in more details. Orbits m.p. 887 and 2062 are crossed near pericenter and apocenter accordingly. So possible interval of the interaction of these objects is repeated through the significant time interval and has relatively small duration. On the strength of several reasons, orbits of fragments of the disastrous collision can have no an exact intersection. Besides, when integrating on the greater gap in the past increases a role of the uncertainty of initial values of elements of orbits. These factors determine a probabilistic nature of the result as well as need of modeling of the disastrous process. However, on the strength of the specific spatial location of orbits, result has highly determined numeric expression - in the suggestion on the possible interaction m. p. 887 and 2062, this event has occurred about 1400 years ago. The possible participation some other near Earth minor objects, include Quadrantides meteoric stream, in described disastrous event is discussed.

description: To develop weather insurance, GROUPAMA builds a general model of agronomic crop yield density function. This approach is applied for cereal, industrial products, wine and fruits. From the density function, weather risk premium is computed. The wine-producing practices disturb our approach of risks. First, wine yields are limited by public regulations. Second, some cooperatives applied quality regulations. Then, observed crop yields are not agronomic crop yields needed by the model. The paper proposes a simulation process to estimate the agronomic parameters of areas crop yields from observed crop yields data. This process is tested on Champagne wine historical data. We measure too the impact of the quantity rules on our estimation of premium. Next, the paper analyses impact on quality on the idiosyncratic risk and on the premium. It results that agronomic parameters give cheaper premium estimation. Because rigorous growing process is implemented, include quality risk is not systemically more expensive but need to compute an individual analyse.

description: We discuss the mechanism of anomalous Hall effect related to the contribution of electron states below the Fermi surface (induced by the Berry phase in momentum space). Our main calculations are made within a model of two-dimensional electron gas with spin-orbit interaction of the Rashba type, taking into account the scattering from impurities. We demonstrate that such an "intrinsic" mechanism can dominate but there is a competition with the impurity-scattering mechanism, related to the contribution of states in the vicinity of Fermi surface. We also show that the contribution to the Hall conductivity from electron states close to the Fermi surface has the intrinsic properties as well.

description: We study the mean traversal time for a class of random walks on Newman-Watts small-world networks, in which steps around the edge of the network occur with a transition rate F that is different from the rate f for steps across small-world connections. When f >> F, the mean time to traverse the network exhibits a transition associated with percolation of the random graph (i.e., small-world) part of the network, and a collapse of the data onto a universal curve. This transition was not observed in earlier studies in which equal transition rates were assumed for all allowed steps. We develop a simple self-consistent effective medium theory and show that it gives a quantitatively correct description of the traversal time in all parameter regimes except the immediate neighborhood of the transition, as is characteristic of most effective medium theories.

description: We present a real-world application that uses a quantum computer. Specifically, we train a RBM using QA for cybersecurity applications. The D-Wave 2000Q has been used to implement QA. RBMs are trained on the ISCX data, which is a benchmark dataset for cybersecurity. For comparison, RBMs are also trained using CD. CD is a commonly used method for RBM training. Our analysis of the ISCX data shows that the dataset is imbalanced. We present two different schemes to balance the training dataset before feeding it to a classifier. The first scheme is based on the undersampling of benign instances. The imbalanced training dataset is divided into five sub-datasets that are trained separately. A majority voting is then performed to get the result. Our results show the majority vote increases the classification accuracy up from 90.24% to 95.68%, in the case of CD. For the case of QA, the classification accuracy increases from 74.14% to 80.04%. In the second scheme, a RBM is used to generate synthetic data to balance the training dataset. We show that both QA and CD-trained RBM can be used to generate useful synthetic data. Balanced training data is used to evaluate several classifiers. Among the classifiers investigated, K-Nearest Neighbor (KNN) and Neural Network (NN) perform better than other classifiers. They both show an accuracy of 93%. Our results show a proof-of-concept that a QA-based RBM can be trained on a 64-bit binary dataset. The illustrative example suggests the possibility to migrate many practical classification problems to QA-based techniques. Further, we show that synthetic data generated from a RBM can be used to balance the original dataset.

description: We present results of a toy model study of performance of the Time-of-Flight detectors integrated into forward proton detectors. The goal of the ToF device is to suppress effects of additional soft processes (so called pile-up) accompanying the hard-scale central diffractive event, characterized by two tagged leading protons, one on each side from the interaction point. The method of mitigation of the pile-up effects exemplified in this study is based on measuring a difference between arrival times of these leading protons at the forward proton detectors and hence estimate the z-coordinate of the production vertex. We evaluate effects of the the pile-up background by studying in detail its components, and estimate the performance of the ToF method as a function of the time and spatial resolution of the ToF device and of the number of pile-up interactions per bunch crossing. We also propose a new observable with a potential to efficiently separate central diffractive signal from the harsh pile-up environment.

description: The paper explores the feasibility of the use of weather index based derivatives for farms' risk management in an Italian province. Based on a combination of detailed local weather data and of data on farms' yields, various possible weather indexes are found that are highly correlated with yields of the major crops in the area. Simulations show that hedging through such index based derivatives can be effective in protecting the stability of farms' incomes, at a cost that is likely to be much lower than that of the current system of subsidized crop insurance and ex-post compensation.

description: Layered heterostructure materials with two different functional building blocks can teach us about emergent physical properties and phenomena arising from interactions between the layers. We report the intergrowth compounds KLa$M$$_{1-x}$Te$_{4}$ ($M$ = Mn, Zn; $x\approx$ 0.35) featuring two chemically distinct alternating layers [LaTe$_3$] and [K$M$$_{1-x}$Te]. Their crystal structures are incommensurate, determined by single X-ray diffraction for the Mn compound and transmission electron microscope (TEM) study for the Zn compound. KLaMn$_{1-x}$Te$_{4}$ crystallizes in the orthorhombic superspace group $Pmnm$(01/2$γ$)$s$00 with lattice parameters $a$ = 4.4815(3) Å, $b$ = 21.6649(16) Å and $c$ = 4.5220(3) Å. It exhibits charge density wave (CDW) order at room temperature with a modulation wave vector $\mathbf{q}$ = 1/2$\mathbf{b}$* + 0.3478$\mathbf{c}$* originating from electronic instability of Te-square nets in [LaTe$_{3}$] layers. The Mn analog exhibits a cluster spin glass behavior with spin freezing temperature $T_{\mathrm{f}}$ $\approx$ 5 K attributed to disordered Mn vacancies and competing magnetic interactions in the [Mn$_{1-x}$Te] layers. The Zn analog also has charge density wave order at room temperature with a similar $\mathbf{q}$-vector having the $\mathbf{c}$* component ~ 0.346 confirmed by selected-area electron diffraction (SAED). Electron transfer from [K$M_{1-x}$Te] to [LaTe$_{3}$] layers exists in KLa$M_{1-x}$Te$_{4}$, leading to an enhanced electronic specific heat coefficient. The resistivities of KLa$M_{1-x}$Te$_{4}$ ($M$ = Mn, Zn) exhibit metallic behavior at high temperatures and an upturn at low temperatures, suggesting partial localization of carriers in the [LaTe$_{3}$] layers with some degree of disorder associated with the $M$ atom vacancies in the [$M_{1-x}$Te] layers.

Structural-functional studies of the non-enzymatic domains of prothrombin
Creators: name: Hung, Vo Cong
Publisher: name: University of British Columbia
Year: 2009

description: To study the role of the non-enzymatic domains of the clotting protein prothrombin, human prothrombin and several variants were produced by using recombinant DNA techniques and in vitro tissue culture expression. The prothrombin variants included the first kringle domain deleted (rΔKl), the second kringle domain deleted (rΔK2), both kringle domains deleted (rΔKl/ΔK2), the second kringle domain substituted with the bovine counterpart (rhBK2), and the second kringle domain substituted with the first kringle (rKl/Kl). The recombinant proteins were expressed by using the pNUT-baby hamster kidney cell system under methotrexate selection. The expressed proteins were purified from the media using barium citrate precipitation followed by fast performance liquid chromatography (FPLC). Different gamma-carboxylated recombinant proteins were resolved by pseudo-affinity FPLC using a calcium gradient. The expressed recombinant proteins subjected to several characterization assays including Gla content analysis by capillary electrophoresis-laser induced fluorescence (CE-LIF), calcium and phospholipid binding assays, and activation assays by factor Xa and by the prothrombinase complex using purified systems. Results from the studies have indicated that a reduced Gla content in the protein, by as little as three residues, led to a substantial loss of calcium dependent phospholipid binding, and a reduced clotting ability. Results from the activation assays of the prothrombin variants have demonstrated that the second kringle domain was necessary for the activation of prothrombin by both the protease factor Xa alone and by the prothrombinase complex, implying important interactions of the second kringle with factor Xa and the cofactor Va. In addition, peptides derived from the loops of the second kringle domain were demonstrated to have potent inhibitory activity in the activation of prothrombin by the prothrombinase complex. Taken together the study has demonstrated that the nonenzymatic domains of prothrombin play important roles in the ability of prothrombin to be activated physiologically. The Gla domain is responsible for calcium and phospholipid binding, the kringle domains mediate protein-protein interactions with the protease factor Xa and cofactor Va of the prothrombinase complex.

De plus, les clients passent très rapidement de la banque traditionnelle à la banque en ligne en raison de divers avantages tels que la rentabilité et la rentabilité. Par conséquent, il est nécessaire d'étudier attentivement l’expérience client avec sa banque physique, et son impact sur l’intention d’utiliser les services bancaires en ligne. Nos résultats suggèrent qu’au-delà de la facilité d’utilisation et de l’utilité du système d’information, les entreprises doivent tirer parti de la relation client établie dans un environnement hors ligne susceptible d’influencer l’intention d’utilisation des clients vis-à-vis du service Internet. L’étude fait progresser la littérature sur l’acceptation de la technologie en expliquant le comportement des nouveaux utilisateurs en matière d’adoption de services.

description: Global attempts to limit greenhouse gas (GHG) emissions may impact on agricultural trade and producer returns, particularly in countries such as New Zealand, where a relatively large proportion of GHG emissions originate from the agricultural sector. This study uses an extended partial equilibrium agricultural trade model to analyze the effects of trade policy liberalization on agricultural production and trade, as well as on GHG emissions. Further analysis combines trade liberalization with GHG mitigation policy in the New Zealand and European dairy sectors, and the effects on producer returns and GHG emissions are predicted. As expected, full trade liberalization in the OECD (Organization for Economic Cooperation and Development) countries enhances producer returns in New Zealand's dairy sector, but reduces returns in the European Union's dairy sector.

description: Galactic core-collapse supernovae are among the possible sources of gravitational waves. We investigate the ability of gravitational-wave observatories to extract the properties of the collapsing progenitor from the gravitational waves radiated. We use simulations of supernovae that explore a variety of progenitor core rotation rates and nuclear equations of state and examine the ability of current and future observatories to determine these properties using gravitational-wave parameter estimation. We use principal component analysis of the simulation catalog to determine the dominant features of the waveforms and create a map between the measured properties of the waveform and the physical properties of the progenitor. We use Bayesian parameter inference and the parameter map to calculate posterior probabilities for the physical properties given a gravitational-wave observation. We estimate the ratio of the progenitor's core rotational kinetic energy to potential energy ($β$) and the post bounce oscillation frequency. For a supernovae at the distance of the galactic center (8.1 kpc) with $β= 0.02$ our method can estimate $β$ with a $90\%$ credible interval of $0.004$ for Advanced LIGO, improving to $0.0008$ for Cosmic Explorer. We demonstrate that if the core is rotating sufficiently rapidly for a signal observed by Cosmic Explorer, our method can also extract the post bounce oscillation frequency of the protoneutron star to a precision of within $5$~Hz ($90\%$ credible interval) allowing us to constrain the nuclear equation of state. For a supernovae at the distance of the Magellanic Clouds (48.5 kpc) Cosmic Explorer's ability to measure these parameters decreases slightly to $0.003$ for rotation and $11$~Hz for the postbounce oscillation frequency ($90\%$ credible interval). Sources in Magellanic Clouds will be too distant for Advanced LIGO to measure these properties.

description: We report the first successful application of the {\it ab initio} quantum Monte Carlo (QMC) framework to a phonon dispersion calculation. A full phonon dispersion of diamond is successfully calculated at the variational Monte Carlo (VMC) level, based on the frozen-phonon technique. The VMC-phonon dispersion is in good agreement with the experimental results, giving renormalized harmonic optical frequencies very close to the experimental values, by significantly improving upon density functional theory (DFT) in the generalized gradient approximation. Key to success for the QMC approach is the statistical error reduction in atomic force evaluation. We show that this can be achieved by using well conditioned atomic basis sets, by explicitly removing the basis-set redundancy, which reduces the statistical error of forces by up to two orders of magnitude. This leads to affordable and accurate QMC-phonons calculations, up to $10^{4}$ times more efficient than previous attempts, and paves the way to new applications, particularly in correlated materials, where phonons have been poorly reproduced so far.

description: This paper examines the elimination of all agricultural policy distortions in all trading countries and agricultural production decisions in the United States, as well as subsequent environmental quality in the presence and absence of nondegradation environmental standards. The results suggest that trade liberalization has the potential to increase domestic production and boost agricultural returns by as much as 8.5 percent. Consumer surplus would likely fall, and the discharge of nutrients, sediment, and pesticides would likely increase. However, environmental policies can limit these adverse environmental impacts and mute the potential decrease in consumer surplus, while leaving increased returns to agricultural production.

description: We present three dimensional smoothed particle hydrodynamics (SPH) calculations of warped accretion discs in X-ray binary systems. Geometrically thin, optically thick accretion discs are illuminated by a central radiation source. This illumination exerts a non-axisymmetric radiation pressure on the surface of the disc resulting in a torque that acts on the disc to induce a twist or warp. Initially planar discs are unstable to warping driven by the radiation torque and in general the warps also precess in a retrograde direction relative to the orbital flow. We simulate a number of X-ray binary systems which have different mass ratios using a number of different luminosities for each. Radiation-driven warping occurs for all systems simulated. For mass ratios q ~ 0.1 a moderate warp occurs in the inner disc while the outer disc remains in the orbital plane (c.f. X 1916-053). For less extreme mass ratios the entire disc tilts out of the orbital plane (c.f. Her X-1). For discs that are tilted out of the orbital plane in which the outer edge material of the disc is precessing in a prograde direction we obtain both positive and negative superhumps simultaneously in the dissipation light curve (c.f. V603 Aql).

description: This paper reviews recent work on the implications of endogenous policy for the effects of trade on the environment and the sustainability of renewable resource stocks. A recognition that pollution policy is endogenous has had a major impact on the trade and environment literature and has reversed some of the previously established empirical findings. Work on pollution has proceeded faster than work on renewable resources. I suggest some directions for future work in this area.
Multi-harmonic correlations of different flow amplitudes in Pb-Pb collisions at $\sqrt{s_{_{\rm NN}}}=2.76$ TeV

description: The event-by-event correlations between three flow amplitudes are measured for the first time in Pb--Pb collisions, using higher-order Symmetric Cumulants. We find that different three-harmonic correlations develop during the collective evolution of the medium, when compared with correlations that exist in the initial state. These new results cannot be interpreted in terms of previous lower-order flow measurements, since contributions from two-harmonic correlations are explicitly removed in the new observables. Comparison with Monte Carlo simulations provides new and independent constraints for the initial conditions and system properties of nuclear matter created in heavy-ion collisions.

Resistively-Detected NMR in a Two-Dimensional Electron System near $ν= 1$: Clues to the Origin of the Dispersive Lineshape

description: Resistively-detected NMR measurements on 2D electron systems near the $ν= 1$ quantum Hall state are reported. In contrast to recent results of Gervais \emph{et al.} [Phys. Rev. Lett. $\bf 94$, 196803 (2005)], a dispersive lineshape is found at all RF powers studied and Korringa-like nuclear spin-lattice relaxation is observed. The shape of the unexplained dispersive lineshape is found to invert when the temperature derivative of the longitudinal resistance changes sign. This suggests that both Zeeman and thermal effects are important to resistively-detected NMR in this regime.

Optimal path of diffusion over the saddle point and fusion of massive nuclei

description: Diffusion of a particle passing over the saddle point of a two-dimensional quadratic potential is studied via a set of coupled Langevin equations and the expression for the passing probability is obtained exactly. The passing probability is found to be strongly influenced by the off-diagonal components of inertia and friction tensors. If the system undergoes the optimal path to pass over the saddle point by taking an appropriate direction of initial velocity into account, which departs from the potential valley and has minimum dissipation, the passing probability should be enhanced. Application to fusion of massive nuclei, we show that there exists the optimal injecting choice for the deformable target and projectile nuclei, namely, the intermediate deformation between spherical and extremely deformed ones which enables the fusion probability to reach its maximum.

description: Chiral symmetry is restored at high density, quarks become nearly massless and pion, the Goldstone of the symmetry breaking decouples from the quarks. What happens at high density is important for finding the density dependence of Strange Quark Matter (SQM), - which in turn is relevant for understanding the structure of compact stars.

Forms of Quantum Nonseparability and Related Philosophical Consequences
Creators: name: Karakostas, Vassilios
Publisher: name: arXiv
Year: 2005
Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: Standard quantum mechanics unquestionably violates the separability principle that classical physics (be it point-like analytic, statistical, or field-theoretic) accustomed us to consider as valid. In this paper, quantum nonseparability is viewed as a consequence of the Hilbert-space quantum mechanical formalism, avoiding thus any direct recourse to the ramifications of Kochen-Specker's argument or Bell's inequality. Depending on the mode of assignment of states to physical systems (unit state vectors versus non-idempotent density operators) we distinguish between strong/relational and weak/deconstructional forms of quantum nonseparability. The origin of the latter is traced down and discussed at length, whereas its relation to the all important concept of potentiality in forming a coherent picture of the puzzling entangled interconnections among spatially separated systems is also considered. Finally, certain philosophical consequences of quantum nonseparability concerning the nature of quantum objects, the question of realism in quantum mechanics, and possible limitations in revealing the actual character of physical reality in its entirety are explored.

description: The effects of the Free Trade Area of the Americas (FTAA) agreement on the forest sectors and resources of member countries are investigated. A model of wood supply within the spatial partial-equilibrium Global Forest Products Model is developed to link international trade and deforestation. The direct effects of tariff changes and the indirect effects of income changes induced by trade liberalization are considered. The FTAA has a small positive impact on the region's forest resources. Higher harvests of industrial roundwood in most countries are offset by increased afforestation due to the income effect of trade liberalization (captured by the environmental Kuznets curve).

description: A highly disaggregated emissions factor model is presented. The model generates changes in emissions and resource use by state and 6-digit NAICS sector. Removal of all U.S. import restrictions is examined. Results for agriculture show that composition effects explain highly varied regional patterns of emission changes. Scale effects are also important for expanding sectors. Quantitative assessments such as this may prove useful in conducting full environmental reviews of U.S. trade agreements consistent with Executive Order 13141 and the Free Trade Act of 2002.
