description: Cresol is among the phenolic compounds that are frequently found in industrial wastewater streams. Most notably, p-cresol has the highest toxicity and the highest permeability effect on skin of all the cresol isomers; hence, wastewater treatment for p-cresol removal is an important issue. This study was aimed at determining a method of removing p-cresol effectively under moderate conditions by catalytic oxidation. To this end, we synthesized a Pt/CeO2-ZrO2-SnO2/SBA-16 catalyst by supporting Pt as the activator and CeO2-ZrO2-SnO2 as the promoter on an SBA-16 support. As concerns the promoter, the introduction of ZrO2 and SnO2 improved its redox properties, and the superior redox properties of Ce0.68Zr0.17Sn0.15O2 facilitated generation of oxidized platinum ions (Pt2+) with a high phenolic compound oxidation capability compared to metallic platinum (Pt0). Among the catalysts prepared, Pt/CeO2-ZrO2-SnO2/SBA-16 with high Pt2+ content exhibited the highest catalytic activity for p-cresol oxidation, and p-cresol was completely removed under moderate reaction conditions of 80°C for 4 h under atmospheric pressure.

description: We present an analysis of sixteen galaxy clusters, one group and one galaxy drawn from the Chandra X-ray Observatory's data archive. These systems possess prominent X-ray surface brightness depressions associated with cavities or bubbles that were created by interactions between powerful radio sources and the surrounding hot gas. The minimum energy associated with the cavities ranges between pV~10^55 erg in galaxies, groups, and poor clusters to pV~10^60 erg in rich clusters. We evaluate the hypothesis that cooling in the hot gas can be quenched by energy injected into the surrounding gas by the rising bubbles. Nearly half of the systems in this study may have instantaneous mechanical luminosities large enough to balance cooling, at least for a short period of time, if the cavities are filled with a relativistic gas. We find a trend or upper envelope in the distribution of central X-ray luminosity versus instantaneous mechanical luminosity with the sense that the most powerful cavities are found in the most X-ray luminous systems. Such a trend would be expected if many of these systems produce bubbles at a rate that scales in proportion to the cooling rate of the surrounding gas. Finally, we use the X-ray cavities to measure the mechanical power of radio sources over six decades of radio luminosity, independently of the radio properties themselves. We find that the ratio of the instantaneous mechanical (kinetic) luminosity to the 1.4 GHz synchrotron luminosity ranges from a few to roughly a thousand. This wide range implies that the 1.4 GHz synchrotron luminosity is an unreliable gauge of the mechanical power of radio sources.

description: We present a model for string breaking based on the existence of chromoelectric flux tubes. We predict the form of the long-range potential, and obtain an estimate of the string breaking length. A prediction is also obtained for the behaviour with temperature of the string breaking length near the deconfinement phase transition. We plan to use this model as a guide for a program of study of string breaking on the lattice.

Perspective: Heusler interfaces -- opportunities beyond spintronics?

Subjects: subject: Materials Science (cond-mat.mtrl-sci)
subject: FOS: Physical sciences

description: Heusler compounds, in both cubic and hexagonal polymorphs, exhibit a remarkable range of electronic, magnetic, elastic, and topological properties, rivaling that of the transition metal oxides. To date, research on these quantum materials has focused primarily on bulk magnetic and thermoelectric properties or on applications in spintronics. More broadly, however, Heuslers provide a platform for discovery and manipulation of emergent properties at well-defined crystalline interfaces. Here, motivated by advances in the epitaxial growth of layered Heusler heterostructures, I present a vision for Heusler interfaces, focusing on the frontiers and challenges that lie beyond spintronics. The ability to grow these materials epitaxially on technologically important semiconductor substrates, such as GaAs, Ge, and Si, provides a direct path for their integration with modern electronics. Further advances will require new methods to control the stoichiometry and defects to "electronic grade" quality, and to control the interface abruptness and ordering at the atomic scale.

description: The main aim of this paper is to report two new detections of tidal debris in the northern stream of the Sagittarius dwarf galaxy located at 45 arcdeg and 55 arcdeg from the center of galaxy. Our observational approach is based on deep color-magnitude diagrams, that provides accurate distances, surface brightness and the properties of stellar population of the studied region of this tidal stream. The derived distances for these tidal debris wraps are 45 kpc and 54 kpc respectively.We also confirm these detections with numerical simulations of the Sagittarius dwarf plus the Milky Way. The model reproduces the present position and velocity of the Sagittarius main body and presents a long tidal stream formed by tidal interaction with the Milky Way potential. This model is also in good agreement with the available observations of the Sagittarius tidal stream. We also present a method for estimating the shape of the Milky Way halo potential using numerical simulations. From our simulations we obtain an oblateness of the Milky Way dark halo potential of 0.85, using the current database of distances and radial velocities of the Sagittarius tidal stream. The color-magnitude diagram of the apocenter of Sagittarius shows that this region of the stream shares the complex star formation history observed in the main body of the galaxy. We present the first evidence for a gradient in the stellar population along the stream, possibly correlated with its different pericenter passages. (abridged)

description: As an alternative inertial confinement fusion scheme with predicted high energy gain and more robust designs, shock ignition requires a strong converging shock driven by a shaped pulse with a high-intensity spike at the end to ignite a pre-compressed fusion capsule. Understanding nonlinear laser-plasma instabilities in shock ignition conditions is crucial to assess and improve the laser-shock energy coupling. Recent experiments conducted on the OMEGA-EP laser facility have for the first time demonstrated that such instabilities can $\sim$100\% deplete the first 0.5 ns of the high-intensity laser pump. Analysis of the observed laser-generated blast wave suggests that this pump-depletion starts at 0.01--0.02 critical density and progresses to 0.1--0.2 critical density. This pump-depletion is also confirmed by the time-resolved stimulated Raman backscattering spectra. The dynamics of the pump-depletion can be explained by the breaking of ion-acoustic waves in stimulated Brillouin scattering. Such strong pump-depletion would inhibit the collisional laser energy absorption but may benefit the generation of hot electrons with moderate temperatures for electron shock ignition [Shang et al. Phys. Rev. Lett. 119 195001 (2017)].

description: We present a lattice determination of the leptonic decay constant F_Ds of the Ds-meson using its mass and F_K as experimental input. Setting the scale with F_K=160 MeV, our final result is F_Ds = 252(9) MeV. The error contains all uncertainties apart from the quenched approximation. Setting the scale with the nucleon mass instead leads to an increase of 3(1) MeV of the leptonic decay constant which might indicate a small quenching error.

description: In this paper we show that the theory of transfer reactions from bound to continuum states is well suited to extract structure information from data obtained by performing "spectroscopy in the continuum". The low energy unbound states of nuclei such as $^{10}$Li and $^{5}$He can be analyzed and the neutron-core interaction, necessary to describe the corresponding borromean nuclei $^{11}$Li and $^{6}$He can be determined in a semi-phenomenological way. An application to the study of $^{10}$Li is then discussed and it is shown that the scattering length for s-states at threshold can be obtained from the ratio of experimental and theoretical cross sections. The scattering single particle states of the system n+$^{9}$Li are obtained in a potential model. The corresponding S-matrix is used to calculate the transfer cross section as a function of the neutron continuum energy with respect to $^{9}$Li. Three different reactions are calculated $^{9}Li(d,p)^{10}Li$, $^{9}Li(^{9}Be,^{8}Be)^{10}Li$, $^{9}Li(^{13}C,^{12}C)^{10}Li$, to check the sensitivity of the results to the target used and in particular to the transfer matching conditions. Thus the sensitivity of the structure information extracted from experimental data on the reaction mechanism is assessed.

Remarks. Records of A. javanicus from Singapore all refer to Duméril et al. (1854a) and Cantor (1847b) who mentioned that Montgomerie reported seeing one “in a solitary instance”. The RBINS has two specimens (RBINS 9952 and RBINS 9953) that were sent to Antwerp Zoo in 1965, and deposited in RBINS as they died en route to Belgium. Therefore, we omit A. javanicus from Singapore’s herpetofauna checklist. Given its distribution from Vietnam, Cambodia, and Thailand south to Peninsular Malaysia, Sumatra, Java, and Borneo, and its broad habitat preference consisting of slow-moving rivers, streams, canals, tidal areas, mudflats, estuaries, coastal swamps, and mangroves (David & Vogel 1996), there is a possibility that A. javanicus may occur in Singapore. However, given the extent of coastal redevelopment, creation of reservoirs, and canalisation, we suspect specimens would have been found by now.

description: The business incubation model has been embraced by numerous countries of the world since the concept was first conceived and developed in the USA. It has now received much attention among policymakers and academics particularly within the field of entrepreneurship and small business research. Even though the popularity of the programme, so many tenant firms are still closing shops before and after their exit from the incubator. The aim of this study was to explore how government policy moderates the relationship between the individual critical success factors (CSF) and incubator performance. The study adopted the evaluative qualitative case study design. The population of the study consisted of ten surveying stakeholders who were purposively chosen between the stakeholders. The study found the evidence of the moderating role of government policy on the relationship between barriers to success and incubator performance. The study recommended that government should develop a user friendly framework that will ease the difficulties incubators usually encounter in the course of providing resources to the incubatees.

description: We present a simple novel derivation, ab initio, of the equations appropriate for stationary axisymmetric spacetimes using the Papapetrou form of the metric (Papapetrou gauge). It is shown that using coordinates which preserve the Papapetrou gauge three separated solutions of the Ernst equations appear in the case of Kerr metric. In this context a parameter arises which represents topological defects induced by an infinite static string along the z axis. Finally, we discuss a simple solution that may be derived from the Kerr ansatz.

description: Soil fertility decline and soil management for crop production are important issues for grain growers in northern New South Wales and southern and central Queensland. In this paper a stochastic dynamic economic analysis of soil fertility management is presented to derive optimal fertility levels, and the management practices to achieve them. A sequential analysis of first deriving the optimal nitrogen stock and application, ceteris paribus, was followed by an assessment of tillage, stubble and fertiliser strategies to obtain an optimal level of soil organic carbon in the soil. The recommended management practices are compared with levels of current usage in the region. The derivation of optimal levels of soil fertility for agricultural purposes may have other policy implications.

description: We estimate the Coulomb energy of static quarks from a Monte Carlo calculation of the correlator of timelike link variables in Coulomb gauge. We find, in agreement with Cucchieri and Zwanziger, that this energy grows linearly with distance at large quark separations. The corresponding string tension, however, is several times greater than the accepted asymptotic string tension, indicating that a state containing only static sources, with no constituent gluons, is not the lowest energy flux tube state. The Coulomb energy is also measured on thermalized lattices with center vortices removed by the de Forcrand-D'Elia procedure. We find that when vortices are removed, the Coulomb string tension vanishes.

description: Discoveries of terrestrial, Earth-sized exoplanets that lie within the habitable zone (HZ) of their host stars continue to occur at increasing rates. Transit spectroscopy can potentially enable the detection of molecular signatures from such worlds, providing an indication of the presence of an atmosphere and its chemical composition, including gases potentially indicative of a biosphere. Such planets around nearby M-dwarf stars - such as TRAPPIST-1 - provide relatively good signal, high signal/noise, and frequent transits for follow-up spectroscopy. However, even with these advantages, transit spectroscopy of terrestrial planets in the HZ of nearby M-stars will still be a challenge. Herein, we examine the potential for future space observatories to conduct such observations, using a Global Climate Model (GCM), a photochemical model, and a radiative transfer suite to simulate modern-Earth-like atmospheric boundary conditions on TRAPPIST-1e. The detectability of biosignatures on such an atmosphere via transmission spectroscopy is modeled for JWST, LUVOIR, HabEx, and Origins. We show that for any of these observatories, only CO2 would be detectable at the 3 sigma level in transmission spectroscopy, when clouds are included in our simulations. This is because the impacts of clouds on scale height strongly limits the detectability of molecules in the atmosphere. Synergies between space- and ground-based spectroscopy may be essential in order to overcome these difficulties.

description: Numerous solutions to the global coffee crisis have been suggested, including some form of supply constraint. UNCTAD’s Agricultural Trade Policy Simulation Model (ATPSM) is used to assess the likely changes in coffee prices and export revenues of effective production constraints. Results indicate that a 10 per cent reduction of exports in the four major producing countries is estimated to increase world prices by 17 per cent and increase these countries' export revenues by 6 per cent in the long run. Other coffee exporters would increase their exports and therefore would gain proportionally more. Further gains would result from the additional production of alternative crops.

description: We present a spectroscopic study of D461, a giant star belonging to Draco dwarf spheroidal galaxy. From spectral synthesis in LTE we derive a lithium abundance of log e(Li)=3.5+/-0.4 and a C/O ratio between 3 and 5. This is the first detection of a lithium rich C-star in a dwarf spheroidal galaxy. Basing on stellar models of appropriate chemical composition, we show that a similar C enrichment is compatible with that expectedfor a low mass low metallicity thermally pulsing AGB star, undergoing few third dredge up episodes. The position in the log g-log Teff diagram of D461 is also compatible with this theoretical scenario. In particular, the low effective temperature, lower than that expected for a low metallicity giant star, is a consequence of the huge increase of the envelope opacity occurring after the carbon dredge up. The Li enrichment may be explained if a deep circulation would take place during the interpulse period, the so called cool bottom process. In spite of the low resolution of our spectra, we derive a lower limit for the carbon isotopic ratio, namely 12C/13C>40, and a constraint for the Ba abundance, namely 0.5

description: A company has faced a challenge in improving its supply chain management and related performances. The importance of managing efficient process flows will lower the overall cost. Hence, the profitability will enlarge. There are five alternatives suggested in this research. The researcher has discussed detailed data analysis and organizational structures. Different models have been tested in this research including the cost model, the price model, and the delivery routing model. Only one alternative is suggested – delivery routing model. The delivery routing model is a systematic and a heuristic approach. The suggestion helps the organization in improving delivery efficiency tremendously.

description: We introduce a model in which the genesis of dark matter (DM) and neutrino masses is associated with a first order phase transition of a scalar singlet field. During the phase transition a source right-handed neutrino (RHN) acquires a spacetime-dependent mass dynamically, a small fraction of which is converted via resonant oscillations into a very weakly mixed dark RHN which decays to a dark matter RHN with the observed relic abundance. Neutrino masses are generated via a traditional two RHN type-I seesaw between a fourth RHN and the source neutrino. The gravitational waves produced during the phase transition have a peak frequency that increases with the DM mass, and are detectable at future gravitational wave interferometers for DM masses above ~ 1 MeV. Since the source RHNs are heavier than the electroweak scale, successful leptogenesis is also attainable.

description: This study explores the cointegration relationship and causal link of internet penetration and broadband subscription to economic growth from the 10 countries of ASEAN for the period 2000-2016. A pooled multiple regression model with GDP growth as a function of internet penetration and broadband subscription was developed. The Johansen-Fisher panel cointegration was applied to determine the presence of a long-run equilibrium relationship among the three variables and the direction of causality was identified by estimating the panel-based vector error correction model (VECM). Results from cointegration test indicate a long run equilibrium relationship between internet penetration, broadband subscription and economic growth. The causality test reveals there is long run causality running from internet penetration and broadband subscription to economic growth. In the short-run, broadband subscription causes economic growth in the ASEAN countries. However, internet penetration has no causal link with economic growth in the short-run during the period 2000-2016. The findings are supportive of the claim that internet penetration and broadband connections are engine of economic growth and are rapidly transforming ASEAN economies. Based on these findings, this study recommends that ASEAN governments should be supportive on policies that promotes better internet and broadband infrastructure to achieved short and long-run economic growth.

description: During magnetically dominated relativistic reconnection, inflowing plasma depletes the initial relativistic pressure at the x-line and collisionless plasma heating inside the diffusion region is insufficient to overcome this loss. The resulting pressure drop causes a collapse at the x-line, essentially a localization mechanism of the diffusion region necessary for fast reconnection. The extension of this low-pressure region further explains the bursty nature of anti-parallel reconnection because a once opened outflow exhaust can also collapse, which repeatedly triggers secondary tearing islands. However, a stable single x-line reconnection can be achieved when an external guide field exists, since the reconnecting magnetic field component rotates out of the reconnection plane at outflows, providing additional magnetic pressure to sustain the opened exhausts.

description: Poverty is an ongoing issue in Ethiopia. The identification of policy options to address the problem primarily requires that poverty be measured accurately. One of the most important ingredients in the measurement of poverty are prices. The magnitude of poverty is affected by how cost of living differences across time and regions are adjusted. This paper derives a set of price indices for Urban Ethiopia using data from four urban household surveys conducted in 1994, 1995, 1997, and 2000. The results show that the cities of Dire Dawa and Mekelle are the two most expensive cities, while Jimma and Bahir Dar are the least expensive. The findings also confirm that poverty is indeed high in urban Ethiopia with poverty head count of over 40 percent. Poverty estimates derived using country level consumer price indexes, which do not adjust for spatial cost of living differences, are misleading. But using poverty lines as deflators to account for price differences does not affect the poverty estimates obtained.

Remarks. Inger & Marx (1965) reported eight unnumbered specimens from Singapore deposited at ZMH and collected by Schwinghammer in 1909. However, they doubted the specimens originated from Singapore as no additional specimens were ever reported and because C. linnaei was commonly sold. Presently, C. linnaei is only known from Java and Bangka (Wallach et al. 2014). de Lang (2017) mentioned that C. linnaei has also been erroneously reported from Borneo, Sulawesi, and Sumatra.

description: We propose an atom-cavity chip that combines laser cooling and trapping of neutral atoms with magnetic microtraps and waveguides to deliver a cold atom to the mode of a fiber taper coupled photonic bandgap (PBG) cavity. The feasibility of this device for detecting single atoms is analyzed using both a semi-classical treatment and an unconditional master equation approach. Single-atom detection seems achievable in an initial experiment involving the non-deterministic delivery of weakly trapped atoms into the mode of the PBG cavity.

description: In this letter, we present an approach for learning in-hand manipulation skills with a low-cost, underactuated prosthetic hand in the presence of irreversible events. Our approach combines reinforcement learning based on visual perception with low-level reactive control based on tactile perception, which aims to avoid slipping. The objective of the reinforcement learning level consists not only in fulfilling the in-hand manipulation goal, but also in minimizing the intervention of the tactile reactive control. This way, the occurrence of object slipping during the learning procedure, which we consider an irreversible event, is significantly reduced. When an irreversible event occurs, the learning process is considered failed. We show the performance in two tasks, which consist in reorienting a cup and a bottle only using the fingers. The experimental results show that the proposed architecture allows reaching the goal in the Cartesian space and reduces significantly the occurrence of object slipping during the learning procedure. Moreover, without the proposed synergy between reactive control and reinforcement learning it was not possible to avoid irreversible events and, therefore, to learn the task.
Measuring the cosmological background of relativistic particles with WMAP

description: We show that the first year results of the Wilkinson Microwave Anisotropy Probe (WMAP) constrain very efficiently the energy density in relativistic particles in the universe. We derive new bounds on additional relativistic degrees of freedom expressed in terms of an excess in the effective number of light neutrinos Delta N_eff. Within the flat LambdaCDM scenario, the allowed range is Delta N_eff < 6 (95% CL) using WMAP data only, or -2.6 < Delta N_eff < 4 with the prior H_0= 72 \pm 8 km/s/Mpc. When other cosmic microwave background and large scale structure experiments are taken into account, the window shrinks to -1.6 < Delta N_eff < 3.8. These results are in perfect agreement with the bounds from primordial nucleosynthesis. Non-minimal cosmological models with extra relativistic degrees of freedom are now severely restricted.

description: In Australia, more than 80 per cent of regional towns and cities have ongoing repair costs due to local infrastructure damage from dryland salinity. In some salt affected catchments up to 30 per cent of regional roads are affected to some degree, with major highway reconstruction costing up to $1million per kilometre. This research investigates a series of different road types in order to quantify the net benefits of alternative abatement strategies and to determine when government intervention is justified to encourage landholders to assist in action to mitigate the impacts of dryland salinity on roads. The paper shows that cooperation with landholders in terms of revegetation strategies is not effective or profitable when dryland salinity is at an advanced stage and already having impacts upon the road. Where suitable revegetation strategies are available, and the risk from dryland salinity is not imminent, then revegetation strategy can be effective and, in some cases, a net benefit to the catchment.
