description: We present an elaborate and systematic study of the conductance properties of a zigzag bilayer graphene nanoribbon modeled by a Kane-Mele (KM) Hamiltonian. The interplay of the Rashba and the intrinsic spin-orbit couplings with the edge states, electronic band structures, charge and spin transport are explored in details. We have analytically derived the conditions for the edge states for a bilayer KM nanoribbon and show how these modes decay for lattice sites inside the bulk. It is particularly interesting to note that for a finite-size ribbon an even number of zigzag ribbon hosts a finite energy gap at the Dirac points, while the odd ones do not. This asymmetry is present both in presence and absence of a bias voltage that may exist between the layers. The interlayer Rashba spin-orbit coupling, along with the intralayer intrinsic spin-orbit and intralayer Rashba spin-orbit couplings seem to destroy the quantum spin Hall (QSH) phase where the QSH phase is identified by the presence of a conductance plateau (of magnitude 4e/h) in the vicinity of zero Fermi energy. The plateau is sensitive to the values of the spin-orbit coupling parameters. Further, the spin polarized conductance data reveal that a bilayer KM ribbon is found to be more efficient for spintronic applications compared to a monolayer graphene. Finally, a quick check with experiments is done via computing the effective mass of electrons.

description: Pomadasys kaakan (Cuvier, 1830)
(no. 11–13 in pl. 1)
  Material examined.  — 6 sagittae (SG 0253-3, 0270-1, 0270-3, 0272-1+0272-2, 0274-9, 0285-3).
  Dimensions.  — OL, 5.76–7.91 mm; OH, 4.03–5.72 mm; OT, 1.34–2.06 mm; OsL, 1.95–3.40 mm; OsH, 0.98–1.49 mm.
  Remarks.  — A comparison of the cauda shape revealed that these specimens were somewhat different from the rest. The cauda curved more gently unlike those from P. argenteus. Specimens SG 0272-1 and SG 0272-2 from a single archaeological spot were recognised as being from the same sagitta (no. 13 in pl. 1) that had broken in the middle. Specimens SG 0270-3, 0272-1+0272-2, 0274-9, 0285-3 have an excisural notch that point upwards, with acute angles and very shallow. Thus five sagittae out of the six specimens were recognised as belonging to P. kaakan.

description: The morphology of thin stellar streams can be used to test the nature of dark matter. It is therefore crucial to extend searches for globular cluster streams to other galaxies than the Milky Way. In this paper, we investigate the current and future prospects of detecting globular cluster streams in external galaxies in resolved stars (e.g. with WFIRST) and using integrated light (e.g. with HSC, LSST and Euclid). In particular, we inject mock-streams to data from the PAndAS M31 survey, and produce simulated M31 backgrounds mimicking what WFIRST will observe in M31. Additionally, we estimate the distance limit to which globular cluster streams will be observable. Our results demonstrate that for a 1 hour (1000 sec.) exposure, using conservative estimates, WFIRST should detect globular cluster streams in resolved stars in galaxies out to distances of ~3.5 Mpc (~2 Mpc). This volume contains 199 (122) galaxies of which >90% are dwarfs. With integrated light, thin streams can be resolved out to ~100 Mpc with HSC and LSST and to ~600 Mpc with WFIRST and Euclid. The low surface brightness of the streams (typically >30 mag/arcsec$^2$), however, will make them difficult to detect, unless the streams originate from very young clusters. We emphasize that if the external galaxies do not host spiral arms or galactic bars, gaps in their stellar streams provide an ideal test case for evidence of interactions with dark matter subhalos. Furthermore, obtaining a large samples of thin stellar streams can help constrain the orbital structure and hence the potentials of external halos.

description: This paper empirically examines the extent to which organization characteristics promote the diffusion of pollution prevention technologies within a firm (parent company). We use panel data on more than 5000 facilities reporting to the Toxics Release Inventory over the period of 1991 to 2011 to examine the number of pollution prevention technologies adopted by a facility with respect to its size, previous experience in adoption, its distances to its sibling facilities and firm’s headquarter, and regional density. We use a two-part hurdle model to estimate the likelihood of adoption and the rate of adoption, while controlling for public and regulatory pressures that may have affected the adoption of pollution prevention technologies. We find that a facility that was located in the same city with its firm’s headquarter were more likely to adopt pollution prevention technologies. Past experience in adoption of pollution prevention technology and firm’s knowledge stock on pollution prevention technology increased both the likelihood and rate of adoption.

description: We report on CCD optical (B and V passbands) and near IR (J and K bands) observations in the region of the old open cluster NGC 2141. By combining the two sets of photometry (500 stars in common) we derive new estimates of the cluster fundamental parameters. We confirm that the cluster is 2.5 Gyrs old, but, with respect to previous investigations, we obtain a slightly larger reddening (E(B-V)=0.40), and a slightly shorter distance (3.8 kpc) from the Sun. Finally we present Luminosity Function (LF) in the V band, which is another age indicator. We provide a good fit for the age range inferred from isochrones by assuming the Kroupa et al. (1993) IMF up to $M_V$=5.0. We interpret the disagreemt at fainter magnitudes as an evidence of mass segregation.

description: We develop an economic model of cellulosic biofuel production under stover supply uncertainty. The model considers three contract arrangements that vary according to risk-sharing between the processor and farmers and allows us to evaluate the processor’s choices of plant size and contract terms that acquire corn stover feedstock with relatively low variability. We apply the model to corn stover-based ethanol in U.S. crop reporting districts. A greater quantity of biofuel is supplied at lower cost under right-of-access contracts than a delivered quantity contract. However, the processor bears most of the stover production risk with right-of-access contracts. The processor can lay off some of this risk by contracting excess acreage, and if available, by purchasing deficit stover from a spot market. Contracting excess acreage increases the expected biofuel cost but results in lower uncertainty surrounding cellulosic biofuel supply. A biomass spot market provides a source of biomass during low yielding years, but can also create competition for the processor by providing an alternative outlet for farmers to supply stover. Our results also suggest that farmers’ contract preferences are responsive to the basic structure of incentives. As the industry develops and market uncertainties change, rigidity of farmers’ contract preferences are not expected to limit the processor’s adjustment process.

description: We have detected the rare phenomenon of stable, drifting sub-pulse behaviour in two pulsars discovered in the recent Swinburne intermediate latitude pulsar survey. The pulsars; PSR J1231-47 and PSR J1919+0134, have approximate periods (P) of 1.873 and 1.6039 seconds respectively. Both pulsars have multi-component profiles, and distinct drifting is observed across them. We have identified a single drift mode in both pulsars: the drift rate for PSR J1231-47 being 5.4(1) ms P^{-1} and 5.8(2) ms P^{-1} for PSR 1919+0134. The drifting is linear across the profile with no departure from linearity at the edges within the sensitivity of our observations.

description: The literature discusses risk aversion as one of the behavioral determinants of technology adoption. However, little attention has been paid to measuring ambiguity aversion of poor people in developing countries or in finding the role of ambiguity aversion in technology adoption. Risk experiments in the previous studies have been designed in such a way that individuals face the risky and/or ambiguous situations alone. Individuals in the real world, especially farmers in developing countries, are likely to get information from peers before making any decision regarding a new innovation that has an ambiguous nature. This paper addresses two broad issues. The first issue is to measure the risk and ambiguity preferences of Bangladeshi rural farmers. The paper investigates whether the attitudes toward uncertainty (risk and ambiguity) differ when farmers face the uncertainty alone versus when they are allowed to communicate with peer groups of 3 or 6. It also investigates whether farmers’ demographic characteristics affect their attitudes toward uncertainty or not. A second issue is to find whether measures of attitudes toward uncertainty is same across different groups of subjects using experimental lotteries. To do so, this paper replicates the same experiments with groups of students in two universities in Bangladesh. Finally, the paper also investigates whether demographic variables affect the attitudes toward risk and ambiguity aversion or not. It finds that risk attitudes of farmers and students are same when deciding alone. However, farmers tend to show higher variation in risk aversion than students sample when deciding in a group of 3. In the latter case, farmers tend to show less risk aversion than students. While disaggregating the measured risk attitudes across gender, female students tend to show more risk aversion as well as higher variation in risk aversion than male students in the sample. The study also finds that The study also finds that students’ and farmers’ demographic characteristics affect both risk and ambiguity aversion.

description: A series of 2,3-difluorophenylene-based negative liquid crystals which own different terminal groups has been synthesised in high yields through many classical named reactions such as Suzuki coupling and Williamson etherification. Thermal properties of these mesogens were tested by differential scanning calorimetry and the effects of the terminal groups on the melting points of molecules were evaluated. Dielectric anisotropies of the synthesised molecules were then measured and found that relatively long alkyl substituents would decrease the Δε value when compared with the ethyl. For the compound with a polar substitute on the long molecular axis, the introduction of 2,2-difluoroethyl would increase the negative Δε when it was put into the opposite direction of the original polar group, making this strategy a new access for the improvement of negative Δε. DFT calculations were carried out to analyse the orientation of the dipole moment in molecules and found that the introduction of 2,2-difluoroethyl had changed the orientation of the dipole moment into nearly perpendicular to the long molecular axis, which benefited the growth of the negative Δε value, revealing the mechanism of this strategy from the view of molecular level to some extent.

description: In this paper, we assess the levels of infrastructure investment and rates for return on investments to reduce postharvest losses (PHL). Food security impacts and rates of return to reducing PHL are compared to rates of return to productivity-increasing research and development (R&D) investment. First we undertake of review of the literature on the magnitude of PHL. Next we undertake an econometric analysis of the impact of infrastructure investments on PHL using a panel data set. Third, we quantify the investments required for any given level of PHL reduction by combining marginal effect analysis based on the econometric estimation with data on unit costs for specific infrastructural variables. Fourth, we undertake a cost-benefit analysis of the required infrastructural investments to assess whether or not significant efforts in PHL reduction are economically feasible; and compare these to the rates of return to investments in R&D. These scenarios show that investment in infrastructure for PHL reduction contributes to lower food prices, higher food availability, and improved food security, and has positive economic rates of return. However, improvements in food security and marginal returns to investment in agricultural research are considerably higher for investment in agricultural research than for investment in PHL reduction. Reductions in PHL are not a low-cost alternative to productivity growth for achieving food security. Rather, reduction in PHL through improved infrastructure requires large public investments and is complementary to investments in long-term productivity growth to achieve food security.

description: The motivation for this study centers on the labor-and cost-intensive nature of wine grape production and the potential opportunities for robotic technology. The study objectives are to develop cost of production budgets for six representative wine grape vineyards in five U.S. states, assess the economic viability of wine grape production under current operating conditions, evaluate labor costs by production task, and identify common production challenges and tasks that could be augmented with robotic technology development. Investigators have worked with grower panels to develop a production budget for representative vineyards in five states, and to gather input on production tasks that the growers and technology developers feel would be most suitable for robotic technology. A stochastic simulation model was developed to assess baseline pro-forma financial statements for each vineyard size. Combined, the results help in exploring opportunities to strengthen vineyard profitability and competitiveness using robotics.

description: We use tunable, vacuum ultraviolet laser-based angle-resolved photoemission spectroscopy and density functional theory calculations to study the electronic properties of Dirac semimetal candidate cubic PtBi${}_{2}$. In addition to bulk electronic states we also find surface states in PtBi${}_{2}$ which is expected as PtBi${}_{2}$ was theoretical predicated to be a candidate Dirac semimetal. The surface states are also well reproduced from DFT band calculations. Interestingly, the topological surface states form Fermi contours rather than double Fermi arcs that were observed in Na$_3$Bi. The surface bands forming the Fermi contours merge with bulk bands in proximity of the Dirac points projections, as expected. Our data confirms existence of Dirac states in PtBi${}_{2}$ and reveals the fragility of the Fermi arcs in Dirac semimetals. Because the Fermi arcs are not topologically protected in general, they can be deformed into Fermi contours, as proposed by [Kargarian {\it et al.}, PNAS \textbf{113}, 8648 (2016)]. Our results demonstrate validity of this theory in PtBi${}_{2}$.

description: In this paper, we implement and study a model-based reinforcement learning (MBRL) method called Policy Optimization for Adaptive Optics (PO4AO) in numerical simulations.
We use the Object-Oriented Python Adaptive Optics (OOPAO) simulation tool to simulate the Provence Adaptive Optics Pyramid Run System (PAPYRUS) optical bench and provide a real-time model of the system. In particular, we demonstrate the predictive capability of the method since the temporal error dominates the error budget of PAPYRYS.
We first present a detailed description of the reinforcement learning framework, including our definition of the state space, the action space, and the reward function.
The experiment section compares PO4AO to a well-tuned integrator in different atmospheric conditions. In conclusion, we discuss the importance of experiments in numerical simulations before applying the method to a real telescope and possible avenues for future work.

description: The ultra-diffuse dwarf galaxy NGC 1052-DF2 (DF2) has ten (eleven) measured globular clusters (GCs) with a line-of-sight velocity dispersion of $σ=7.8^{+5.2}_{-2.2}\,$km/s ($σ=10.6^{+3.9}_{-2.3}\,$km/s). Our conventional statistical analysis of the original ten GCs gives $σ=8.0^{+4.3}_{-3.0}\,$km/s. The overall distribution of velocities agrees well with a Gaussian of this width. Due to the non-linear Poisson equation in MOND, a dwarf galaxy has weaker self-gravity when in close proximity to a massive host. This external field effect is investigated using a new analytic formulation and fully self-consistent live $N$-body models in MOND. Our formulation agrees well with that of Famaey and McGaugh (2012). These new simulations confirm our analytic results and suggest that DF2 may be in a deep-freeze state unique to MOND. The correctly calculated MOND velocity dispersion agrees with our inferred dispersion and that of van Dokkum et al. (2018b) if DF2 is within 150 kpc of NGC 1052 and both are 20 Mpc away. The GCs of DF2 are however significantly brighter and larger than normal GCs, a problem which disappears if DF2 is significantly closer to us. A distance of 10-13 Mpc makes DF2 a normal dwarf galaxy even more consistent with MOND and the 13 Mpc distance reported by Trujillo et. al. (2019). We discuss the similar dwarf DF4, finding good agreement with MOND. We also discuss possible massive galaxies near DF2 and DF4 along with their distances and peculiar velocities, noting that NGC 1052 may lie at a distance near 10 Mpc.

description: China maintains a steady yield increase in the past three decades, but farm production is undergoing a great change, especially in the recent decade, due to the change in both economic conditions and the environment along with a sharp decline of rural labor and farming population. Agricultural mechanization, especially agricultural mechanization services (AMS), gains its popularity in recent years. This study examines the adoption of agricultural mechanization, using either self-equipped machinery or AMS; and the factors contributing to the adoption of different types of agricultural mechanization. The empirical analysis uses primary survey data and employs a seemingly unrelated regression model. We find that the agricultural labor endowment improves the adoption of agricultural mechanization, but off-farm labor curbs the adoption. In terms of the land endowment, we find an inverse U-shaped non-linear relationship between the land endowment and the AMS adoption, and land fragmentation reduces the mechanization adoption.

description: We report on microwave-induced resistance oscillations (MIROs) in a tunable-density 30-nm-wide GaAs/AlGaAs quantum well. We find that the MIRO amplitude increases dramatically with carrier density. Our analysis shows that the anticipated increase in the effective microwave power and quantum lifetime with density is not sufficient to explain the observed growth of the amplitude. We further observe that the fundamental oscillation extrema move towards cyclotron resonance with increasing density, which also contradicts theoretical predictions. These findings reveal that the density dependence is not properly captured by existing theories, calling for further studies.

Determining the Composition of Relativistic Jets from Polarization Maps

description: We present a stationary, axisymmetric, self-similar semi-analytic model of magnetically dominated jet plasma based on force-free regions of a relativistic magnetohydrodynamic simulation. We use this model to illustrate how the composition of relativistic jet plasma can be determined, with special attention to the example of M87. In particular, we compute synthetic Stokes maps in e-e+p plasmas with various positron-to-proton ratios using synchrotron emission models scaling the partial pressure of electrons and positrons emitting at the observed frequency to the magnetic pressure, taking into account Faraday rotation and conversion. The lepton-dominated models produce bilaterally asymmetric radio intensity profiles with strong linear polarization and Stokes Q and U maps that are bilaterally asymmetric (but strongly up-down correlated) and antisymmetric (and sometimes up-down anticorrelated), respectively. The hadronic models produce more centrally brightened intensity and polarization maps. Circular polarization provides the cleanest observational tool for distinguishing the plasmas, as it increases outward from the jet core and central axis for highly ionic plasma, and is suppressed for pair dominated plasma. We find a measurable degree of circular polarization V/I of O(10e-3) for sub-equipartition hadronic jet plasmas. Our stationary model predicts that the intensity-normalized autocorrelation functions of Q and U increase and decrease with frequency, respectively. On the other hand, the autocorrelation of V is less sensitive to the frequency. Multi-band polarimetric observations could therefore be used as a novel probe of the composition of jet plasma.

description: We are witness to a great and increasing interest in internal structure, composition and evolution of exoplanets. However, direct measurements of exoplanetary mass and radius cannot be uniquely interpreted in terms of interior structure, justifying the need for an additional observable. The second degree fluid Love number, $k_2$, is proportional to the concentration of mass towards the body's center, hence providing valuable additional information about the internal structure. When hydrostatic equilibrium is assumed for the planetary interior, $k_2$ is a direct function of the planetary shape. Previous attempts were made to link the observed tidally and rotationally induced planetary oblateness in photometric light curves to $k_2$ using ellipsoidal shape models. Here, we construct an analytical 3D shape model function of the true planetary mean radius, that properly accounts for tidal and rotational deformations. Measuring the true planetary mean radius is critical when one wishes to compare the measured $k_2$ to interior theoretical expectations. We illustrate the feasibility of our method and show, by applying a Differential Evolution Markov Chain to synthetic data of WASP-121b, that a precision $\leq$ 65 ppm/$\sqrt{2\,min}$ is required to reliably retrieve $k_2$ with present understanding of stellar limb darkening, therefore improving recent results based on ellipsoidal shape models. Any improvement on stellar limb darkening would increase such performance.
