description: We present a previously unexplored forward-mode differentiation method for Maxwell's equations, with applications in the field of sensitivity analysis. This approach yields exact gradients and is similar to the popular adjoint variable method, but provides a significant improvement in both memory and speed scaling for problems involving several output parameters, as we analyze in the context of finite-difference time-domain (FDTD) simulations. Furthermore, it provides an exact alternative to numerical derivative methods, based on finite-difference approximations. To demonstrate the usefulness of the method, we perform sensitivity analysis of two problems. First we compute how the spatial near-field intensity distribution of a scatterer changes with respect to its dielectric constant. Then, we compute how the spectral power and coupling efficiency of a surface grating coupler changes with respect to its fill factor.

description: Strain can affect the morphology of a crystal surface, and cause modifications of its reconstruction even when weak, as in the case of mechanical bending. We carried out calculations of strain-dependent surface free energy and direct bending simulations demonstrating the change of incommensurate reconstruction in Au(111) under strain, in good agreement with recent data. Time-dependent strain should cause a sliding of the topmost layer over the second, suggesting an interesting case of nanofriction. Bending strain could also be used to fine tune the spacing of selectively absorbed nanoclusters.

Quantum impurity solvers using a slave rotor representation
Creators: name: Florens, Serge

Publisher: name: arXiv

Subjects: subject: Strongly Correlated Electrons (cond-mat.str-el)
subject: FOS: Physical sciences

description: We introduce a representation of electron operators as a product of a spin-carry ing fermion and of a phase variable dual to the total charge (slave quantum rotor). Based on this representation, a new method is proposed for solving multi-orbital Anderson quantum impurity models at finite interaction strength U. It consists in a set of coupled integral equations for the auxiliary field Green's functions, which can be derived from a controlled saddle-point in the limit of a large number of field components. In contrast to some finite-U extensions of the non-crossing approximation, the new method provides a smooth interpolation between the atomic limit and the weak-coupling limit, and does not display violation of causality at low-frequency. We demonstrate that this impurity solver can be applied in the context of Dynamical Mean-Field Theory, at or close to half-filling. Good agreement with established results on the Mott transition is found, and large values of the orbital degeneracy can be investigated at low computational cost.

The Variability of the Star Formation Rate in Galaxies: I. Star Formation Histories Traced by EW(H$α$) and EW(H$δ_A$)

subject: FOS: Physical sciences

description: To investigate the variability of the star formation rate (SFR) of galaxies, we define a star formation change parameter, SFR$_{\rm 5Myr}$/SFR$_{\rm 800Myr}$ which is the ratio of the SFR averaged within the last 5 Myr to the SFR averaged within the last 800 Myr. We show that this parameter can be determined from a combination of H$α$ emission and H$δ$ absorption, plus the 4000 A break, with an uncertainty of $\sim$0.07 dex for star-forming galaxies. We then apply this estimator to MaNGA galaxies, both globally within Re and within radial annuli. We find that galaxies with higher global SFR$_{\rm 5Myr}$/SFR$_{\rm 800Myr}$ appear to have higher SFR$_{\rm 5Myr}$/SFR$_{\rm 800Myr}$ at all galactic radii, i.e. that galaxies with a recent temporal enhancement in overall SFR have enhanced star formation at all galactic radii. The dispersion of the SFR$_{\rm 5Myr}$/SFR$_{\rm 800Myr}$ at a given relative galactic radius and a given stellar mass decreases with the (indirectly inferred) gas depletion time: locations with short gas depletion time appear to undergo bigger variations in their star-formation rates on Gyr or less timescales. In Wang et al. (2019) we showed that the dispersion in star-formation rate surface densities $Σ_{\rm SFR}$ in the galaxy population appears to be inversely correlated with the inferred gas depletion timescale and interpreted this in terms of the dynamical response of a gas-regulator system to changes in the gas inflow rate. In this paper, we can now prove directly with SFR$_{\rm 5Myr}$/SFR$_{\rm 800Myr}$ that these effects are indeed due to genuine temporal variations in the SFR of individual galaxies on timescales between $10^7$ and $10^9$ years rather than possibly reflecting intrinsic, non-temporal, differences between different galaxies.

 Distribution
Previously recorded (see Kott 1992a): Western Australia (Fremantle); Victoria (Portland Canyons). New record: Tasmanian Canyons (Banks Strait, 168 m).
 Remarks
The newly recorded specimen has been assigned to this temperate species on the basis of the upright club-shaped colony, narrowing to the base, identical with one previously reported from Portland, Victoria (see Kott 1992a, Figure 42a). The test is soft and translucent. The species is characterised principally by the presence of only four rows of stigmata and identification of the newly recorded specimen cannot be firm because zooids are in vegetative state, with minute regenerating thoraces and long vegetative posterior abdomina.

description: The research reported in this paper is focused on the cost-effectiveness of intervention strategies to reduce pollution loads and improve water quality in South-east Queensland. Strategies considered include point and non-point source interventions. Predicted reductions in pollution levels were calculated for each action based on the expected population growth. The costs of the interventions included the full investment and annual running costs as well as planned public investment by the state agencies. The results show that the cost-effectiveness of strategies is likely to vary according to whether suspended sediments, nitrogen or phosphorus loads are being targeted.

description: Chandra observations of the supermassive black hole in the nucleus of IC1459 show a weak [L_X=8x10(40)erg s(-1), 0.3-8keV], unabsorbed nuclear X-ray source, with a slope Gamma=1.88+/-0.09, and no strong Fe-K line at 6.4keV (EW$<382 eV). This describes a normal AGN X-ray spectrum, but lies at 3x10(-7) below the Eddington limit. The SED of the IC1459 nucleus is extremely radio loud compared to normal radio-loud quasars. The nucleus is surrounded by hot ISM (kT~0.5-0.6 keV) with an average density of 0.3cm(-3), within the central ~180 pc radius, which is comparable to the gravitational capture radius, r_A~140 pc. We estimate that for a standard AGN efficiency of 10%, the Bondi accretion would correspond to a luminosity of ~6x10(44)erg s(-1), nearly four orders of magnitude higher than L_X. ADAF solutions can explain the X-ray spectrum, but not the high radio/X-ray ratio. A jet model fits the radio-100micron and X-ray spectra well. The total power in this jet is ~10% of L(Bondi), implying that accretion close to the Bondi rate is needed.

description: We introduce a generalized ensemble of nonhermitian matrices interpolating between the Gaussian Unitary Ensemble, the Ginibre ensemble and the Poisson ensemble. The joint eigenvalue distribution of this model is obtained by means of an extension of the Itzykson-Zuber formula to general complex matrices. Its correlation functions are studied both in the case of weak nonhermiticity and in the case of strong nonhermiticity. In the weak nonhermiticity limit we show that the spectral correlations in the bulk of the spectrum display critical statistics: the asymptotic linear behavior of the number variance is already approached for energy differences of the order of the eigenvalue spacing. To lowest order, its slope does not depend on the degree of nonhermiticity. Close the edge, the spectral correlations are similar to the Hermitian case. In the strong nonhermiticity limit the crossover behavior from the Ginibre ensemble to the Poisson ensemble first appears close to the surface of the spectrum. Our model may be relevant for the description of the spectral correlations of an open disordered system close to an Anderson transition.

description: We study the Large Magellanic Cloud (LMC) star clusters R 127 and R 128 using imaging and spectroscopy obtained at the ESO NTT telescope. An advanced image restoration technique allows us to resolve these two clusters into at least 14 and 33 stars respectively and obtain their photometry. In particular, we show that the core of R 127 is composed of at least four stars and identify the Luminous Blue Variable (LBV) component. The closest neighbor of the LBV (star #8) is 1".5 away. Moreover, from medium dispersion spectroscopy we determine the spectral types for 19 stars in and near both clusters, and in particular present the first spatially resolved observation of the second brightest component of the R 127 cluster (star #3) situated 3".3 from the LBV. By comparing with evolutionary models we also look into the stellar ages. The oldest stars of the cluster are ~ 6-8 Myr old, whereas the most massive star of the region (#7), formed ~ 3 Myr ago as an 80 solar mass star, has turned into an LBV, the ``R 127'' star.

description: The effects of carrying capacity of environment $K$ for degradation (the $K$ effect for short) on the constitutive gene expression and a simple genetic regulation system, are investigated by employing a stochastic Langevin equation combined with the corresponding Fokker-Planck equation for the two stochastic systems subjected to internal and external noises. This $K$ effect characterizes the limited degradation ability of the environment for RNA or proteins, such as insufficient catabolic enzymes. The $K$ effect could significantly change the distribution of mRNA copy-number in constitutive gene expression, and interestingly, it leads to the Fano factor slightly larger than 1 if only the internal noise exists. Therefore, that the recent experimental measurements suggests the Fano factor deviates from 1 slightly (Science {\bf 346} (2014) 1533), probably originates from the $K$ effect. The $K$ effects on the steady and transient properties of genetic regulation system, have been investigated in detail. It could enhance the mean first passage time significantly especially when the noises are weak and reduce the signal-to-noise ratio in stochastic resonance substantially.

description: Based on the questionnaire of 10 sample ancient towns and villages in Shanxi Province, we analyze the poverty occurrence characteristics of ancient towns and villages in Shanxi Province: the poverty incidence in ancient towns and villages is high, with the slow pace of poverty reduction; the regional characteristics of poverty is prominent; there are conspicuous differences in income between residents living in old houses and residents not living in old houses; poverty reduction shows vulnerability and instability. Then we put forward countermeasures for poverty reduction of ancient towns and villages in Shanxi Province as follows: first, improving the targeting mechanism of poverty in ancient towns and villages; second, speeding up the development of agricultural industrialization in ancient towns and villages; third, advancing internal “urbanization” of ancient towns and villages and new countryside construction; fourth, strengthening infrastructure building in ancient towns and villages; fifth, providing fair and efficient allocation of resources, and reducing regional differences; sixth, promoting the ability of residents in ancient towns and villages to cope with poverty vulnerability.

description: We study, at zero temperature, the dynamics of a single electron in a Holstein model augmented by site-diagonal, binary-alloy type disorder. The average over the phonon vacuum and the alloy configurations is performed within a generalized dynamical coherent potential approximation. We present numerical results for a Bethe lattice with infinite coordination number. In particular, we investigate, in the intermediate electron-phonon coupling regime, the spectral and diffusion properties in the vicinity of the high-energy edge of the lowest polaronic subband. To characterize the diffusion properties, we define a spectrally resolved delocalization time, which is, for a given energy, the characteristic time scale on which the electron leaves a given site. We find the delocalization times substantially enhanced for states with a large phonon content, i.e., in the absence (presence) of alloy-type disorder at the high-energy edge(s) of the polaronic subband (mini-subbands). According to their delocalization times, we discriminate between ``fast'' quasi-particle-like and ``sluggish'' defect-like polaron states and qualitatively address the issue of trapping of an electronic carrier.

description: To investigate the characteristics of service value of the karst rocky desertification ecosystem, we take water conservation, soil conservation, carbon-fixation and oxygen-production, production of organic matter, and purification of atmospheric environment as function indicators, to conduct quantitative assessment and analysis of service function value of ecosystem in Yachi Town, Bijie City; Hongfenghu Town, Qingzhen City; Guanling-Zhenfeng Huajiang Demonstration Area in Guizhou Province, using remote sensing and field monitoring data in 2006. The results show that the rate of contribution of water conservation, soil conservation, carbon-fixation and oxygen-production functions to regional service value is high (37.05%, 36.68% and 23.15%, respectively); the rate of contribution of production of organic matter and purification of atmospheric environment functions to regional service value is low (2.80% and 0.32%, respectively). The ranking of landscape in terms of service value per unit area is as follows: forestland (23.3539 million yuan)> shrub land (10.6301 million yuan)> grassland (5.0367 million yuan)>dry land (3.3812 million yuan)> farmland (2.5088 million yuan). The ranking of demonstration areas in terms of service value per unit area is as follows: Yachi Demonstration Area (12.44 million yuan)> Hongfenghu Demonstration Area (5.91 million yuan)> Huajiang Demonstration Area (4.4 million yuan). It is negatively correlated with rocky desertification incidence within the region. The results also indicate that in the process of restoring and reconstructing the ecological environment in rocky desertification areas, increasing the area of forest vegetation, promoting the conversion of dry land and farmland into forestland, shrub land and grassland, will contribute to enhancement in ecological service value.

description: Non-invasive imaging of apoptosis in tumors induced by chemotherapy is of great value in the evaluation of therapeutic efficiency. In this study, we report the synthesis, characterization, and utilization of radionuclide technetium-99m (99mTc)-labeled dendrimer-entrapped gold nanoparticles (Au DENPs) for targeted SPECT/CT imaging of chemotherapy-induced tumor apoptosis. Generation five poly(amidoamine) (PAMAM) dendrimers (G5.NH2) were sequentially conjugated with 1,4,7,10-tetraazacyclododecane-1,4,7,10-tetraacetic acid (DOTA), polyethylene glycol (PEG) modified duramycin, PEG monomethyl ether, and fluorescein isothiocyanate (FI) to form the multifunctional dendrimers, which were then utilized as templates to entrap gold nanoparticles. Followed by acetylation of the remaining dendrimer surface amines and radiolabeling of 99mTc, the SPECT/CT dual mode nanoprobe of tumor apoptosis was constructed. The developed multifunctional Au DENPs before and after 99mTc radiolabeling were well characterized. The results demonstrate that the multifunctional Au DENPs display favorable colloidal stability under different conditions, own good cytocompatibility in the given concentration range, and can be effectively labeled by 99mTc with high radiochemical stability. Furthermore, the multifunctional nanoprobe enables the targeted SPECT/CT imaging of apoptotic cancer cells in vitro and tumor apoptosis after doxorubicin (DOX) treatment in the established subcutaneous tumor model in vivo. The designed duramycin-functionalized Au DENPs might have the potential to be employed as a nanoplatform for the detection of apoptosis and early tumor response to chemotherapy.

description: We address the emergent quantum critical phenomena for (pseudo)spin-3/2 birefringent fermions, featuring two effective Fermi velocities, when they reside close to itinerant Mott transitions realized through spontaneous symmetry breaking and triggered by strong local or Hubbardlike repulsive interactions. Irrespective of the nature of the mass orderings that produce fully gapped quasiparticle spectra in the ordered phase, which otherwise can be grouped into three classes, the system always possesses a \emph{unique} terminal velocity near the corresponding quantum critical point. The associated critical regime accommodates a relativistic non-Fermi liquid of strongly coupled collective bosonic and spin-1/2 Dirac excitations with vanishing weight of the quasiparticle pole. These conclusions are also operative near superconducting critical points. Therefore, relativistic non-Fermi liquid possibly constitutes a robust superuniversal description for the entire family of strongly correlated arbitrary half-integer spin Dirac materials.

description: Cohesive powders tend to form porous aggregates which can be compacted by applying an external pressure. This process is modelled using the Contact Dynamics method supplemented with a cohesion law and rolling friction. Starting with ballistic deposits of varying density, we investigate how the porosity of the compacted sample depends on the cohesion strength and the friction coefficients. This allows to explain different pore stabilization mechanisms. The final porosity depends on the cohesion force scaled by the external pressure and on the lateral distance between branches of the ballistic deposit r_capt. Even if cohesion is switched off, pores can be stabilized by Coulomb friction alone. This effect is weak for round particles, as long as the friction coefficient is smaller than 1. However, for nonspherical particles the effect is much stronger.

description: Based on the Chinese provincial panel data during the period 2003-2010, we conduct empirical test on whether China's rapidly rising prices of agricultural products narrow the urban-rural income gap. The empirical results indicate that the effects of rising agricultural prices on the urban-rural income gap show U shape: within some range of rise, the rising agricultural prices are conducive to narrowing the urban-rural income gap; when the rise is too sharp, it will widen the urban-rural income gap. In the multiple factors fueling the uptick in agricultural prices, rising labor costs in rural areas is an important factor, and the rising agricultural prices driven by this factor can significantly reduce the urban-rural income gap. Therefore, when the government regulates agricultural prices, there is a need to act according to the specific factors, and it should maintain certain "tolerance" for the modest rise in the agricultural prices that contributes to the increase in farmers' income, to avoid over-regulation at the expense of urban and rural residents' income convergence.

description: A realistic inflow boundary condition is essential for successful simulation of the developing turbulent boundary layer or channel flows. Recent advances in artificial intelligence (AI) have enabled the development of an inflow generator that performs better than the synthetic methods based on intuitions. In the present work, we applied generative adversarial networks (GANs), a representative of unsupervised learning, to generate an inlet boundary condition of turbulent channel flow. Upon learning the two-dimensional spatial structure of turbulence using data obtained from direct numerical simulation (DNS) of turbulent channel flow, the GAN could generate instantaneous flow fields that are statistically similar to those of DNS. Surprisingly, the GAN could produce fields at various Reynolds numbers without any additional simulation based on the trained data of only three Reynolds numbers. This indicates that the GAN could learn the universal nature of Reynolds number effect and might reflect other simulation conditions. Eventually, through a combination of the GAN and a recurrent neural network (RNN), we developed a novel model (RNN-GAN) that could generate time-varying fully developed flow for a long time. The spatiotemporal correlations of the generated flow are in good agreement with those of the DNS. This proves the usefulness of unsupervised learning in the generation of synthetic turbulence fields.

description: A new era in radioastronomy will begin with the upcoming large-scale surveys planned at the Australian Square Kilometre Array Pathfinder (ASKAP). ASKAP started its Early Science program in October 2017 and several target fields were observed during the array commissioning phase. The SCORPIO field was the first observed in the Galactic Plane in Band 1 (792-1032 MHz) using 15 commissioned antennas. The achieved sensitivity and large field of view already allow to discover new sources and survey thousands of existing ones with improved precision with respect to previous surveys. Data analysis is currently ongoing to deliver the first source catalogue. Given the increased scale of the data, source extraction and characterization, even in this Early Science phase, have to be carried out in a mostly automated way. This process presents significant challenges due to the presence of extended objects and diffuse emission close to the Galactic Plane. In this context we have extended and optimized a novel source finding tool, named CAESAR , to allow extraction of both compact and extended sources from radio maps. A number of developments have been done driven by the analysis of the SCORPIO map and in view of the future ASKAP Galactic Plane survey. The main goals are the improvement of algorithm performances and scalability as well as of software maintainability and usability within the radio community. In this paper we present the current status of CAESAR and report a first systematic characterization of its performance for both compact and extended sources using simulated maps. Future prospects are discussed in light of the obtained results.

description: The study aims to promote the off-season cut roses industry in Hainan Province to the whole island and even whole China. Based on the production data in latest three years, the theory of time value was introduced to analyze the economic benefits of cut roses planting in South Hainan. According to the research findings, the cut roses create a NPV of ￥22 000//667㎡ with a net NPV rate of 34.24%，an internal rate of return of 76.36%，and a dynamic payback of 1.05, bringing the farmers a revenue of ￥7 200/667㎡ per capita per year. Since the large-scale planting of cut roses needs a high investment, it is suggested that the government should increase its support for the cut rose industry.
Periodicity in fields of elongating dunes

description: Dune fields are commonly associated with periodic patterns that are among the most recognizable landscapes on Earth and other planetary bodies. However, in zones of limited sediment supply, where periodic dunes elongate and align in the direction of the resultant sand flux, there has been no attempt to explain the emergence of such a regular pattern. Here, we show, by means of numerical simulations, that the elongation growth mechanism does not produce a pattern with a specific wavelength. Periodic elongating dunes appear to be a juxtaposition of individual structures, the arrangement of which is due to regular landforms at the border of the field acting as boundary conditions. This includes, among others, dune patterns resulting from bed instability, or the crestline reorganization induced by dune migration. The wavelength selection in fields of elongating dunes therefore reflects the interdependence of dune patterns over the course of their evolution.

description: Cut flower production in Yunnan accounts for 80% nationwide. In order to expand the Yunnan Flower sales channels, the promotion of the development of e-commerce is necessary. In 2012 China's online shopping users reached 247 million people, but e-commerce of fresh flowers lagged behind due to the constraints of preservation facilities and logistics cost. The analysis of the factors restricting the development of floral e-commerce and the proposition of solutions to this problem can promote faster development of Yunnan floral e-commerce.
Effect of quantum lattice fluctuations on the optical-absorption spectra of halogen-bridged mixed-valence transition-metal complexes

description: The effect of quantum lattice fluctuations on the optical-absorption spectra in the ground state of halogen-bridged mixed-valence transition-metal linear-chain complexes is studied by using a one-dimensional extended Peierls-Hubbard model. The nonadiabatic effects due to finite phonon frequency $ω_π>0$ are treated through an energy-dependent electron-phonon scattering function $δ(k^{\prime},k)$ introduced by means of an unitary transformation. The calculated optical-absorption spectra do not have the inverse-square-root singularity, but they have a peak above the gap edge and there exists a significant tail below the peak, which are consistent with the optical-absorption coefficient or the optical conductivity measurements of this material.

description: We define a Floer-homology invariant for knots in an oriented three-manifold, closely related to the holomorphic disk Floer homologies for three-manifolds defined in an earlier paper. We set up basic properties of these invariants, including an Euler characteristic calculation, behaviour under connected sums. Then, we establish a relationship with $HF^+$ for surgeries along the knot. Applications include calculation of $HF^+$ of three-manifolds obtained by surgeries on some special knots in $S^3$, and also calculation of $HF^+$ for certain simple three-manifolds which fiber over the circle.

description: The development of specialty agriculture is of great significance to western China’s agricultural structure adjustment, and it’s an essential way for the construction of ecological agriculture in Southern Ningxia mountainous area. This paper makes a summary about the development status of specialty agriculture in Southern Ningxia Mountainous Area and put forward the basic benefit goal and problems needing attention. On this basis, the paper studies the development pattern of specialty agriculture in Southern Ningxia Mountainous Area from the aspects of production factors and industry. This paper suggests that the development pattern of specialty agriculture in Southern Ningxia Mountainous Area should combine the regional agricultural pattern and innovative organization structure pattern, demonstration agriculture and market-directing pattern, engineering agricultural pattern and enterprise-driven pattern. The development of specialty agriculture in Southern Ningxia Mountainous Area should promote the three patterns, in order to achieve the construction of ecological agriculture and agricultural structure adjustment.

Ultra high energy cosmic ray sources & experimental results

subject: FOS: Physical sciences

description: Here we discuss the latest developments in the debate, where the ultrahigh energy cosmic ray particles come from. In this brief review, we emphasize the predictions that necessarily follow from the various concepts proposed. We discuss both sources and propagation, and spend some space on the by now most conservative model, giant radio galaxies and their hot spots and jets, because it allows more steps in the reasoning to be checked, and is more tightly constrained than any other model. It has survived about forty years of debate already. We summarize the task ahead of us at the end, including the development of new technologies to observe ultra high energy cosmic rays, e.g., with the radio emission of air showers, which may lead to an alternative to the fluorescence detectors with their small duty cycle. Due to HiRes, AUGER, and the plans for EUSO, the future is bright, and the ultra high energy cosmic ray particles may yet allow us to explore new physics.

Quantum Creation of a Toy Universe without Inflation

description: We propose a toy model for the origin of the universe, where the scale-invariant fluctuations are generated together with the quantum creation process of the universe. The fluctuations arise inside an instanton in the Euclidean domain of time. In the Lorentzian point of view, the universe emerges with passive, coherent and scale-invariant fluctuations present from the beginning, without the need of inflation or a bounce. For this mechanism to work, we need anisotropic scaling in space and time, which is realized in a toy model of Horava-Lifshitz gravity with a Lifshitz scalar field.
