Japan Trench

description: This volume covers Legs 56 and 57 of the cruises of the Drilling Vessel Glomar Challenger. The Japan Trench area was identified three years ago as a favorable place for studying convergent margins. The IPOD Active Margins Panel focused its attention on testing the simple conceptual model of convergent margins in settings along continental and island arc margins. The Japanese IPOD committee and panel members suggested a series of sites that were designed to (1) characterize the deep ocean basin sediment, (2) explore the accretionary wedge of the lower slope, (3) date the development of the midslope terrace, (4) measure at least a minimum rate of uplift of the shelf edge structure high, (5) test the seaward extent and age of continental crust, (6) indicate the age and geologic history of the deep sea terrace, and (7) examine diagenetic and structural changes of rocks subjected to stresses associated with plate convergence. Thus the main objectives of the Japan Trench transect were to learn more about the mechanism and dynamics of plate convergence and their effects on the sedimentation complex. The Japan Trench transect constitutes one of the first studies of a convergent margin using both multichannel seismic reflection and multihole deep sea drilling data. This volume contains the results of that study by the shipboard participants of Legs 56 and 57 and by their shore-based colleagues. A principal objective of this interdisciplinary study was to determine the evolution of the Japan convergent margin and the style of tectonism at the landward slope of the Japan Trench. Legs 56 and 57 departed from and terminated in Yokohama, Japan and took place between September and December of 1977.

description: The principal limits for the accuracy of the resonance frequency measurements set by the asymmetry of the natural resonance line shape are studied and applied to the recent accurate frequency measurements in the two-photon 1s-2s resonance and in the one-photon 1s-2p resonance in hydrogen atom. This limit for 1s-2s resonance is found to be $\sim 10^{-5}$ Hz compared to the accuracy achieved in experiment $\pm 46$ Hz. In case of deuterium atom the limit is essentially larger: $10^{-2}$ Hz. For 1s-2p resonance the accuracy limit is 0.17 MHz while the uncertainty of the recent frequency measurement is about 6 MHz.

Subjects: Web 2.0 Controlled Sharing

description: Web 2.0 users need usable mechanisms for sharing
    their content with each other in a controlled manner across
    boundaries of content-hosting or application-service providers
    (CSPs). In this paper, we present a solution that builds upon
    existing secret-link mechanism, and augment OpenID identity
    providers with OpenIDemail and Role-based Trust-management
    Policy Service (RTPS). OpenIDemail extends existing OpenID
    protocol to enable OpenID identity providers to use email as
    an alternative identifier and RTPS provides services for internet
    users to organize their online credentials and polices, and for
    CSPs to make access decisions. The proposed solution does not
    require user to setup another account on each CSP to view
    shared content and does not require any special software being
    installed. The mechanism for content hosting and sharing are
    separated, CSPs do not need to change their existing accesscontrol
    mechanisms.

description: Linear regression is a basic and widely-used methodology in data analysis. It is known that some quantum algorithms efficiently perform least squares linear regression of an exponentially large data set. However, if we obtain values of the regression coefficients as classical data, the complexity of the existing quantum algorithms can be larger than the classical method. This is because it depends strongly on the tolerance error $ε$: the best one among the existing proposals is $O(ε^{-2})$. In this paper, we propose the new quantum algorithm for linear regression, which has the complexity of $O(ε^{-1})$ and keeps the logarithmic dependence on the number of data points $N_D$. In this method, we overcome bottleneck parts in the calculation, which take the form of the sum over data points and therefore have the complexity proportional to $N_D$, using quantum amplitude estimation, and other parts classically. Additionally, we generalize our method to some class of convex optimization problems.

description: In this paper we describe ideas about the string landscape, and how to relate it to the physics of the Standard Model of particle physics. First, we give a short status report about heterotic string compactifications. Then we focus on the statistics of D-brane models, on the problem of moduli stabilization, and finally on some attempts to derive a probability wave function in moduli space, which goes beyond the purely statistical count of string vacua.

description: Emission line galaxies (ELGs), more generally star-forming galaxies, are valuable tracers of large-scale structure and therefore main targets of upcoming wide-area spectroscopic galaxy surveys. We propose a fixed-aperture shape estimator of each ELG for extracting the intrinsic alignment (IA) signal, and assess the performance of the method using image simulations of ELGs generated from the IllustrisTNG simulation including observational effects such as the sky background noise. We show that our method enables a significant detection of the IA power spectrum with the linear-scale coefficient $A_{\rm IA}\simeq (13$--$15)\pm 3.0$ up to $z=2$, even from the small simulation volume $\sim0.009\,(h^{-1}{\rm Gpc})^3$, in contrast to the null detection with the standard method. Thus the ELG IA signal, measured with our method, opens up opportunities to exploit cosmology and galaxy physics in high-redshift universe.

description: Food systems in developed countries face one major challenge, namely the promotion of diets that are both healthy and generate less greenhouse gas emissions (GHGE). In this article, we review papers evaluating the impact of a change in diets on both health and GHGE. We address the following questions: How big are the health and environmental impacts that could be induced by a switch to healthier diets? In monetary value, what is the relative importance of the health impact and the environmental impact? Is it possible to design an economic policy to increase global welfare that also takes into account the externalities on both health and the environment? Since the way the change in diet is modeled is a key issue, we classify papers according to the methodology used for simulating diet changes: ad hoc scenarios, optimized diets, and economic modeling. We find that it is possible to design economic policies that have positive impacts on both dimension. Because the substitutions/complementarities between food products are complex, it is not granted that a policy targeting one dimension will generate positive effects on the other dimensions. However, given the diversity of substitution and the complementarity possibilities between products, it is possible to design a policy that does improve both dimensions. A carbon-based tax policy that targets the products with a high greenhouse gas content (e.g., meat products) and reinvests the revenues collected with the tax to subsidize the consumption of fruit and vegetables, is likely to have positive effects on both dimensions.

description: In a large-scale enterprise system, making authorization decisions is often computationally expensive due to the complexity of the policies involved and the large size of the resource and user populations. Given today's trends, computing resources and network bandwidth will become more and more affordable, yet network latency will remain an obstacle. Pre-computing authorizations in advance and delivering them to the PEP cache will enable new tradeoffs between processor/network utilization and network delays. We report preliminary results of investigating what we labeled as "speculative authorizations."

description: We study the potential of fully-differential measurements of high-energy dilepton cross-sections at the LHC to probe heavy new physics encapsulated in dimension-6 interaction operators. The assessment is performed in the seven-dimensional parameter space of operators that induce energy-growing corrections to the Standard Model partonic cross-sections at the interference level, and in the two-dimensional subspace associated with the W and Y parameters. A considerable sensitivity improvement is found relative to single-differential measurements, owing to the possibility of probing at the interference level more directions in the seven-dimensional parameter space. The reduction of parton distribution function uncertainties in the fully-differential fit is also found to play a significant role. The results are interpreted in the minimal Z' new-physics model, providing a concrete illustration of the advantages of the fully-differential analysis. We find that high-energy dilepton measurements can extend the Z' exclusion and discovery potential well beyond the reach of direct searches in a large region of the parameter space.

description: Weakly nonlinear dynamics in anti-de Sitter (AdS) spacetimes is reviewed, keeping an eye on the AdS instability conjecture and focusing on the resonant approximation that accurately captures in a simplified form the long-term evolution of small initial data. Topics covered include turbulent and regular motion, dynamical recurrences analogous to the Fermi-Pasta-Ulam phenomena in oscillator chains, and relations between AdS dynamics and nonrelativistic nonlinear Schrodinger equations in harmonic potentials. Special mention is given to the way the classical dynamics of weakly nonlinear strongly resonant systems is illuminated by perturbative considerations within the corresponding quantum theories, in particular, in relation to quantum chaos theory.

Microcanonical quantum fluctuation theorems

description: Previously derived expressions for the characteristic function of work performed on a quantum system by a classical external force are generalized to arbitrary initial states of the considered system and to Hamiltonians with degenerate spectra. In the particular case of microcanonical initial states explicit expressions for the characteristic function and the corresponding probability density of work are formulated. Their classical limit as well as their relations to the respective canonical expressions are discussed. A fluctuation theorem is derived that expresses the ratio of probabilities of work for a process and its time reversal to the ratio of densities of states of the microcanonical equilibrium systems with corresponding initial and final Hamiltonians.From this Crooks-type fluctuation theorem a relation between entropies of different systems can be derived which does not involve the time reversed process. This entropy-from-work theorem provides an experimentally accessible way to measure entropies.

description: We show that in the anisotropic Hořava-Lifshitz gravity there is a well-defined wave zone where the physical degrees of freedom propagate according to a non-relativistic linear evolution equation of high order in spatial derivatives, which reduces to the wave equation at low energy. This is so, provided the coupling parameters satisfy some restrictions which we study in detail. They are imposed to obtain a finite ADM gravitational energy, which depends manifestly on the terms which break the Lorentz symmetry of the formulation. The analysis we perform is beyond the linearized approach and includes all high order terms of the Hamiltonian potential.

Analysis of ANSI RBAC Support in Commercial Middleware

description: This thesis analyzes the access control architectures of three middleware technologies: Common
Object Request Broker Architecture (CORBA), Enterprise Java Beans (EJB), and Component
Object Model (COM+). For all technologies under study, we formalize the protection state of their
corresponding authorization architectures in a more precise and less ambiguous language than their
respective specifcations. We also suggest algorithms that defne the semantics of authorization
decisions in CORBA, EJB, and COM+. Using the formalized protection state confgurations, we
analyze the level of support for the American National Standard Institute's (ANSI) specifcation
of Role-Based Access Control (RBAC) components and functional specifcation in the studied
middleware technologies. This thesis establishes a framework for assessing implementations of
ANSI RBAC in the analyzed middleware technologies.
Our fndings indicate that all of three middleware technologies under study fall short of supporting
even Core ANSI RBAC. Custom extensions are necessary in order for implementations
compliant with each middleware to support ANSI RBAC required or optional components. Some
of the limitations preventing support of ANSI RBAC are due to the middleware's architectural
design decisions; however, fundamental limitations exist due to the impracticality of some aspects
of the ANSI RBAC standard itself.
Biosorption combined with lipid production and growth inhibition of copper on the microalgal Pediastrum sp.

Year: 2019

description: The contamination of heavy metals in surface waters is an environmental concern due to their persistence and non-degradation that poses a risk to the ecosystem and human health. Microalgae have been known for their ability to remove metals from wastewater and to produce biodiesel. In this study, the copper (Cu) stress on the growth and lipid contents of the green microalgal Pediastrum sp. were evaluated along with the removal capacity. The green microalga was grown in a culture medium with the presence of copper at concentrations of 0, 0.1, 0.5, 2, 5 and 15 mg/L for one week. Results indicated that the growing tolerance levels of Pediastrum sp. in the presence of copper up to 2 mg/L and Cu inhibited the algal growth with the 96h-EC50 value of 6.67 mg/L. However, the Pediastrum sp. showed a promising metal removal efficiency. Cu removal was from 83 to 95% by Pediastrum sp. with an initial concentration of Cu less than 2 mg/L. The presence of a low level of Cu increased the lipid yield up to 18%, but a high concentration of Cu has resulted in low removal efficiencies and decreasing lipid accumulation. The present study suggested the potential of employing green microalgae for wastewater treatment and biodiesel.

description: Due to utilization increase of chemical fertilizers and manures and of a large water volume for irrigation, agricultural runoff has significantly accelerated water pollution. The Red River locates in Vietnam where agriculture plays an important role in the country’s economy. This paper presented the observation results of organic matters concentrations in agricultural runoff from different plant fields (vegetable, flower and rice) in the Red River Delta in 2013 -2014. The results showed that DOC concentrations varied in a high range from 1.0 mg.L-1 to 37.1 mg.L-1, averaging 10.2 ± 6.2 mg.L-1 whereas POC concentrations varied from 0.5 to 4.5 mg.L-1, averaging 1.7 ± 0.7 mg.L-1 for a total 104 samples observed. TOC concentrations in water from the vegetable and flower fields (11.7 ± 7.3 mg.L-1 and 12.6 ± 6.0 mg.L-1 respectively) were higher than the one from the rice field (8.5 ± 6.6 mg.L-1). Lower organic matters concentrations were found in the rainy season than in the dry season due to dilution process. The results suggest the needs for regularly monitoring and efforts to control organic matter pollution from agricultural runoff in the Red River basin or other river basins in developing countries.

description: We revisit a supersymmetric string model for space-time foam, in which bosonic open-string states, such as photons, can possess quantum-gravity-induced velocity fluctuations in vacuum. We argue that the suggestion of light speed variation with lower bound from gamma-ray burst photon time delays can serve as a support for this string-inspired framework, through connecting the experimental finding with model predictions. We also derive the value of the effective quantum-gravity mass in this framework, and give a qualitative study on the model-dependent coefficients. Constraints from birefringent effects and/or photon decays, including the novel $γ$-decay constraint obtained here from the latest Tibet AS$γ$ near-PeV photon, are also found to be consistent with predictions in such a quantum-gravity scheme. Future observation that can testify further the theory is suggested.

description: Accretion-powered X-ray pulsars are among the most luminous X-ray sources in the Galaxy. However, despite decades of theoretical and observational work since their discovery, no satisfactory model for the formation of the observed X-ray spectra has emerged. In this paper, we report on a self-consistent calculation of the spectrum emerging from a pulsar accretion column that includes an explicit treatment of the bulk and thermal Comptonization occurring in the radiation-dominated shocks that form in the accretion flows. Using a rigorous eigenfunction expansion method, we obtain a closed-form expression for the Green's function describing the upscattering of monochromatic radiation injected into the column. The Green's function is convolved with bremsstrahlung, cyclotron, and blackbody source terms to calculate the emergent photon spectrum. We show that energization of photons in the shock naturally produces an X-ray spectrum with a relatively flat continuum and a high-energy exponential cutoff. Finally, we demonstrate that our model yields good agreement with the spectra of the bright pulsar Her X-1 and the low luminosity pulsar X Per.

description: In this paper, we determine periodicity of quantum walks defined by mixed paths and mixed cycles. By the spectral mapping theorem of quantum walks, consideration of periodicity is reduced to eigenvalue analysis of $η$-Hermitian adjacency matrices. First, we investigate coefficients of the characteristic polynomials of $η$-Hermitian adjacency matrices. We show that the characteristic polynomials of mixed trees and their underlying graphs are same. We also define $n+1$ types of mixed cycles and show that every mixed cycle is switching equivalent to one of them. We use these results to discuss periodicity. We show that the mixed paths are periodic for any $η$. In addition, we provide a necessary and sufficient condition for a mixed cycle to be periodic and determine their periods.

In each case, the sensitivities to MSSM soft-breaking terms are compared, laying emphasis on possible correlations among observables. In most scenarios, rare K decays offer unique windows into the Delta S=1 sector of the soft-breaking terms. Therefore, together with B-physics and collider observables, these modes will be essential for reconstructing the still elusive SUSY-breaking mechanism.

description: We present X-ray and radio observations of what may be the closest type Iax supernova (SN) to date, SN 2014dt (d=12.3-19.3 Mpc) and provide tight constraints on the radio and X-ray emission. We infer a specific radio luminosity of < (1.0-2.4)E25 erg/s/Hz at a frequency of 7.5 GHz and a X-ray luminosity < 1.4E38 erg/s (0.3-10 keV) at ~38-48 days post-explosion. We interpret these limits in the context of Inverse Compton (IC) emission and synchrotron emission from a population of electrons accelerated at the forward shock of the explosion in a power-law distribution $N_e(γ_e)\propto γ_e^{-p}$ with p=3. Our analysis constrains the progenitor system mass-loss rate to be smaller than 5E-6 solar masses per year at distances where r <= 1E16 cm for an assumed wind velocity v=100 km/s, and a fraction of post-shock energy into magnetic fields and relativistic electrons of epsilon_B=0.01 and epsilon_e=0.1, respectively. This result rules out some of the parameter space of symbiotic giant star companions, and it is consistent with the low mass-loss rates expected from He-star companions. Our calculations also show that the improved sensitivity of the next generation Very Large Array (ngVLA) is needed to probe the very low-density media characteristic of He stars that are the leading model for binary stellar companions of white dwarfs giving origin to type Iax SNe.

description: We report the low-temperature properties of SrNd$_2$O$_4$, a geometrically frustrated magnet. Magnetisation and heat capacity measurements performed on polycrystalline samples indicate the appearance of a magnetically ordered state at $T_{\rm N}=2.28(4)$~K. Powder neutron diffraction measurements reveal that an \afm\ state with the propagation vector \QV\ is stabilised below this temperature. The magnetic order is incomplete, as only one of the two Nd$^{3+}$ sites carries a significant magnetic moment while the other site remains largely disordered. The presence of a disordered magnetic component below $T_{\rm N}$ is confirmed with polarised neutron diffraction measurements. In an applied magnetic field, the bulk properties measurements indicate a phase transition at about 30~kOe. We construct a tentative $H$-$T$ phase diagram of \sno\ from these measurements.

Subjects: Web 2.0 Controlled Sharing

description: Web 2.0 users need usable mechanisms for sharing their content with each other in a controlled manner across boundaries of content-hosting or application-service providers (CSPs). In this paper, we propose an approach for Web 2.0 content sharing beyond walled gardens. The system is built upon the existing secret-link mechanism and augments OpenID identity providers with both an OpenIDemail extension and a role-based trust-management policy service (RTPS). OpenIDemail extends the existing OpenID protocol to enable OpenID identity providers to use email as an alternative identifier. RTPS provides services for internet users to organize their online credentials and polices, and for CSPs to make access decisions. With our approach, the users do not need to setup an account on each CSP and do not require any special software installed to view shared content. The functionalities for content sharing using secret-link are shifted from CSPs to OpenIDemail providers. CSPs do not need to change their existing user management and access-control mechanisms. In addition, policy statements are URI-addressable, and same access policies can be reused and enforced across CSPs.

description: We present the stellar calibrator sample and the conversion from instrumental to physical units for the 24 micron channel of the Multiband Imaging Photometer for Spitzer (MIPS). The primary calibrators are A stars, and the calibration factor based on those stars is 4.54*10^{-2} MJy sr^{-1} (DN/s)^{-1}, with a nominal uncertainty of 2%. We discuss the data-reduction procedures required to attain this accuracy; without these procdures, the calibration factor obtained using the automated pipeline at the Spitzer Science Center is 1.6% +/- 0.6% lower. We extend this work to predict 24 micron flux densities for a sample of 238 stars which covers a larger range of flux densities and spectral types. We present a total of 348 measurements of 141 stars at 24 micron. This sample covers a factor of ~460 in 24 micron flux density, from 8.6 mJy up to 4.0 Jy. We show that the calibration is linear over that range with respect to target flux and background level. The calibration is based on observations made using 3-second exposures; a preliminary analysis shows that the calibration factor may be 1% and 2% lower for 10- and 30-second exposures, respectively. We also demonstrate that the calibration is very stable: over the course of the mission, repeated measurements of our routine calibrator, HD 159330, show a root-mean-square scatter of only 0.4%. Finally, we show that the point spread function (PSF) is well measured and allows us to calibrate extended sources accurately; Infrared Astronomy Satellite (IRAS) and MIPS measurements of a sample of nearby galaxies are identical within the uncertainties.

description: Web 2.0 users need usable mechanisms for sharing their content with each other in a controlled manner across boundaries of content-hosting or application-service providers (CSPs). In this presentation, we describe the architecture, design, and implementation of a proposed system for Web 2.0 content sharing across CSPs. The system is built upon the existing secret-link mechanism and augments OpenID identity providers with both an OpenIDemail extension and a role-based trust-management policy service (RTPS). OpenIDemail extends the existing OpenID protocol to enable OpenID identity providers to use email as an alternative identifier. RTPS provides services for internet users to organize their online credentials and polices, and for CSPs to make access decisions. To evaluate our approach, we implemented a system named OpenRT in J2EE. OpenRT does not require the end user to setup an account on each CSP to view shared content and does not require the user to install any special software. The mechanisms for content hosting and sharing are separated; CSPs do not need to change their existing access-control mechanisms.

description: We extended dynamic time warping (DTW) into interval-based dynamic time warping (iDTW), including (A) interval-based representation (iRep): [1] abstracting raw, time-stamped data into interval-based abstractions, [2] comparison-period scoping, [3] partitioning abstract intervals into a given temporal granularity; (B) interval-based matching (iMatch): matching partitioned, abstract-concepts records, using a modified DTW. Using domain knowledge, we abstracted the raw data of medical records, for up to three concepts out of four or five relevant concepts, into two interval types: State abstractions (e.g. LOW, HIGH) and Gradient abstractions (e.g. INCREASING, DECREASING). We created all uni-dimensional (State or Gradient) or multi-dimensional (State and Gradient) abstraction combinations. Tasks: Classifying 161 oncology patients records as autologous or allogenic bone-marrow transplantation; classifying 125 hepatitis patients records as B or C hepatitis; predicting micro- or macro-albuminuria in the next year for 151 Type 2 diabetes patients. We used a k-Nearest-Neighbors majority, k = an odd number from 1 to SQRT(N), N = set size. 75,936 10-fold cross-validation experiments were performed: 33,600 (Oncology), 28,800 (Hepatitis), 13,536 (Diabetes). Measures: Area Under the Curve (AUC), optimal Youden's Index. Paired t-tests compared result vectors for equivalent configurations other than a tested variable, to determine a significant mean accuracy difference (P<0.05). Mean classification and prediction using abstractions was significantly better than using only raw time-stamped data. In each domain, at least one abstraction combination led to a significantly better mean performance than raw data. Increasing feature number and using Multi-dimensional abstractions enhanced performance. Unlike when using raw data, optimal mean performance was often reached with k=5, using abstractions.

description: The absolute calibration and characterization of the Multiband Imaging Photometer for Spitzer (MIPS) 70 micron coarse- and fine-scale imaging modes are presented based on over 2.5 years of observations. Accurate photometry (especially for faint sources) requires two simple processing steps beyond the standard data reduction to remove long-term detector transients. Point spread function (PSF) fitting photometry is found to give more accurate flux densities than aperture photometry. Based on the PSF fitting photometry, the calibration factor shows no strong trend with flux density, background, spectral type, exposure time, or time since anneals. The coarse-scale calibration sample includes observations of stars with flux densities from 22 mJy to 17 Jy, on backgrounds from 4 to 26 MJy sr^-1, and with spectral types from B to M. The coarse-scale calibration is 702 +/- 35 MJy sr^-1 MIPS70^-1 (5% uncertainty) and is based on measurements of 66 stars. The instrumental units of the MIPS 70 micron coarse- and fine-scale imaging modes are called MIPS70 and MIPS70F, respectively. The photometric repeatability is calculated to be 4.5% from two stars measured during every MIPS campaign and includes variations on all time scales probed. The preliminary fine-scale calibration factor is 2894 +/- 294 MJy sr^-1 MIPS70F^-1 (10% uncertainty) based on 10 stars. The uncertainty in the coarse- and fine-scale calibration factors are dominated by the 4.5% photometric repeatability and the small sample size, respectively. The 5-sigma, 500 s sensitivity of the coarse-scale observations is 6-8 mJy. This work shows that the MIPS 70 micron array produces accurate, well calibrated photometry and validates the MIPS 70 micron operating strategy, especially the use of frequent stimulator flashes to track the changing responsivities of the Ge:Ga detectors.

description: We study the phase diagram and critical properties of quantum Ising chains with long-range ferromagnetic interactions decaying in a power-law fashion with exponent $α$, in regimes of direct interest for current trapped ion experiments. Using large-scale path integral Monte Carlo simulations, we investigate both the ground-state and the nonzero-temperature regimes. We identify the phase boundary of the ferromagnetic phase and obtain accurate estimates for the ferromagnetic-paramagnetic transition temperatures. We further determine the critical exponents of the respective transitions. Our results are in agreement with existing predictions for interaction exponents $α> 1$ up to small deviations in some critical exponents. We also address the elusive regime $α< 1$, where we find that the universality class of both the ground-state and nonzero-temperature transition is consistent with the mean-field limit at $α= 0$. Our work not only contributes to the understanding of the equilibrium properties of long-range interacting quantum Ising models, but can also be important for addressing fundamental dynamical aspects, such as issues concerning the open question of thermalization in such models.
