description: The so$(2,1)$ Lie algebra is applied to three classes of two- and three-dimensional Smorodinsky-Winternitz super-integrable potentials for which the path integral discussion has been recently presented in the literature. We have constructed the Green's functions for two important super-integrable potentials in $R^{2}.$ Among the super-integrable potentials in $R^{3}$, we have considered two examples, one is maximally super-integrable and another one minimally super-integrable. The discussion is made in various coordinate systems. The energy spectrum and the suitably normalized wave functions of bound and continuous states are then deduced.

description: We propose a novel realization for a topologically superconducting phase hosting Majorana zero-modes on the basis of quantum spin Hall systems. Remarkably, our proposal is completely free of ferromagnets. Instead, we confine helical edge states around a narrow defect line of finite length in a two-dimensional topological insulator. We demonstrate the formation of a new topological regime, hosting protected Majorana modes in the presence of s-wave superconductivity and Zeeman coupling. Interestingly, when the system is weakly tunnel-coupled to helical edge state reservoirs, a particular transport signature is associated with the presence of a non-Abelian Majorana zero-mode.

description: We study a two-state symmetric noise, with a given waiting time distribution $ψ(τ)$, and focus our attention on the connection between the four-time and the two-time correlation functions. The transition of $ψ(τ)$ from the exponential to the non-exponential condition yields the breakdown of the usual factorization condition of high-order correlation functions, as well as the birth of aging effects. We discuss the subtle connections between these two properties, and establish the condition that the Liouville-like approach has to satisfy in order to produce a correct description of the resulting diffusion process.

description: The effective interaction between two classical nonrelativistic electrons (positrons) in the presence of intense electromagnetic radiation (one and two waves) is theoretically studied. Small relativistic corrections are taking into account in the laboratory reference frame. The field of an intense wave forms the movement of particles in such a way that their trajectories are practically parallel for quite a long time, and in the perpendicular direction the particles shift slightly, approaching first and then moving away from each other. This result can be considered as an effective attraction of same charged particles. Shown that the effective attraction of two electrons and two positrons could be substantially asymmetric.

description: Experimental evidence of mode-selective evanescent power coupling at telecommunication frequencies with efficiencies up to 75 % from a tapered optical fiber to a carefully designed metal nanoparticle plasmon waveguide is presented. The waveguide consists of a two-dimensional square lattice of lithographically defined Au nanoparticles on an optically thin silicon membrane. The dispersion and attenuation properties of the waveguide are analyzed using the fiber taper. The high efficiency of power transfer into these waveguides solves the coupling problem between conventional optics and plasmonic devices and could lead to the development of highly efficient plasmonic sensors and optical switches.

description: The structure formation of the dense interstellar material and the fragmentation of clumps into cores is a fundamental step to understand how stars and stellar clusters form. We aim to establish a statistical view of clump fragmentation at sub-parsec scales based on a large sample of massive clumps selected from the ATLASGAL survey. We used the APEX/SABOCA camera at 350 $μ$m to image clumps at a resolution of 8.$''$5. The majority of the sample consists of massive clumps that are weak or in absorption at 24 $μ$m. We resolve rich filamentary structures and identify the population of compact sources. We use association with mid-infrared 22-24 $μ$m and 70 $μ$m point sources to pin down the star formation activity of the cores. We then statistically assess their physical properties, and the fragmentation characteristics of massive clumps. We find a moderate correlation between the clump fragmentation levels with the clump gas density and the predicted number of fragments with pure Jeans fragmentation scenario; we find a strong correlation between the mass of the most massive fragment and the total clump mass, suggesting that the self-gravity may play an important role in the clumps' small scale structure formation. We identify 27 massive quiescent cores with $M_{\rm core}>100$ M$_{\odot}$ within 5 kpc; these are massive enough to be self-gravitating but do not yet show any sign of star-formation. This sample comprises, therefore, promising candidates of massive pre-stellar cores, or deeply embedded high-mass protostars.

description: Both State and Federal governments are keen to foster the development of new industries. Recently the harvesting of kangaroos for human consumption has emerged as a potential industry with important social, economic and conservation benefits. In order to satisfy the increasing consumer demand for kangaroo meet, the kangaroo industry needs to expand its infa-structure in terms of the number and location of harvesters and storage and processing facilities. Using spatial equilibrium modelling this paper identifies the potential infa-structure of the Queensland Kangaroo Harvesting Industry resulting from changes in the harvest off-take rate.

description: We study the slow phase of thermally activated magnetic relaxation in finite two-dimensional ensembles of dipolar interacting ferromagnetic nanoparticles whose easy axes of magnetization are perpendicular to the distribution plane. We develop a method to numerically simulate the magnetic relaxation for the case that the smallest heights of the potential barriers between the equilibrium directions of the nanoparticle magnetic moments are much larger than the thermal energy. Within this framework, we analyze in detail the role that the correlations of the nanoparticle magnetic moments and the finite size of the nanoparticle ensemble play in magnetic relaxation.

description: Recent analyses of the Planck data and quasars at high redshifts have suggested possible deviations from the flat $Λ$ cold dark matter model ($Λ$CDM), where $Λ$ is the cosmological constant. Here we use machine learning methods to investigate any possible deviations from $Λ$CDM at both low and high redshifts by using the latest cosmological data. Specifically, we apply the Genetic Algorithms to explore the nature of dark energy (DE) in a model independent fashion by reconstructing its equation of state $w(z)$, the growth index of matter density perturbations $γ(z)$, the linear DE anisotropic stress $η_\textrm{DE}(z)$ and the adiabatic sound speed $c_\textrm{s,DE}^2(z)$ of DE perturbations. We find a $\sim2σ$ deviation of $w(z)$ from -1 at high redshifts, the adiabatic sound speed is negative at the $\sim2.5σ$ level at $z=0.1$ and a $\sim2σ$ deviation of the anisotropic stress from unity at low redshifts and $\sim4 σ$ at high redshifts. These results hint towards either the presence of an non-adiabatic component in the DE sound speed or the presence of DE anisotropic stress, thus hinting at possible deviations from the $Λ$CDM model.

description: Previous bioeconomic studies have mainly concentrated on beef operations, principally stocker activities, and rangeland conditions. These studies have assumed that the rancher determines some desired weight gain per head over a period, usually one year, and this weight gain is achieved by utilizing a resource such as pasture or grazing rangeland. This study differs to the previous research as we are interested in the interactions between pasture productivity and milk yield in an intensive grazing situation, rather than extensive grazing and incorporate more than one type of pasture or forage type into a model of a dairy system. We develop a discrete optimal control model based on the energy demand of a herd of dairy cows and the supply of energy available from the various forages produced on a model dairy farm. The objective of the model is to maximize the net present value of the flow of profits generated by the dairy. Incorporated into the model is a herd dynamics sub-model, a transferable quota trading equation, and a milk revenue function.

description: On-site wastewater treatment systems (OWTS) are designed to treat wastewater on site, in a decentralized manner. If sited or managed poorly, OWTS can become significant sources of contamination to streams and marine waters. We conducted an assessment of Hawaiʻi’s legal, regulatory, and management provisions of OWTS in relation to the US EPA’s recommended guidelines that are meant to reduce failures and protect human and environmental health. We assessed Hawaiʻi’s capacities to meet US EPA’s recommendations and best management practices. We found that although the state implements some programs and regulations that meet the guidelines, many are missing. The analysis shows a deficiency in a number of areas, including alignment between land use and watershed-based planning, performance goals, inventory of systems, public outreach, homeowner education, and mechanisms that ensure regular upkeep and maintenance. Policy recommendations are provided to increase capacities to better plan for and manage OWTS in Hawaiʻi.

description: In many developed countries the focus of fisheries management has widened to include not only the activities of commercial operators, but also those of recreation anglers. As a consequence there is a growing need for information about the preferences, motives, and values of anglers. This information is needed by managers to help formulate policies for conserving stocks and also for reallocating fish stocks between user groups. This paper critically reviews the random utility model as a technique for describing recreation demand, and shows how the model can be incorporated into a framework for simulating the impacts of various policies over time.
Crossovers in spin-boson and central spin models

description: We discuss how the crossovers in models like spin-boson model are changed by adding the coupling of the central spin to localised modes- the latter modelled as a 'spin bath'. These modes contain most of the environmental entropy and energy at low T in solid-state systems. We find that the low T crossover between oscillator bath and spin bath dominated decoherence, occurring as one reduces the energy scale of the central spin, is characterised by very low decoherence- we show how this works out in practise in magnetic insulators. We then reconsider the standard quantum-classical crossover in the dynamics of a tunneling system, including both spin and oscillator baths. It is found that the general effect of the spin bath is to broaden the crossover in temperature between the quantum and classical activated regimes. The example of tunneling nanomagnets is used to illustrate this.

description: The impairment of cognitive function in Alzheimer's is clearly correlated to synapse loss. However, the mechanisms underlying this correlation are only poorly understood. Here, we investigate how the loss of excitatory synapses in sparsely connected random networks of spiking excitatory and inhibitory neurons alters their dynamical characteristics. Beyond the effects on the network's activity statistics, we find that the loss of excitatory synapses on excitatory neurons shifts the network dynamic towards the stable regime. The decrease in sensitivity to small perturbations to time varying input can be considered as an indication of a reduction of computational capacity. A full recovery of the network performance can be achieved by firing rate homeostasis, here implemented by an up-scaling of the remaining excitatory-excitatory synapses. By analysing the stability of the linearized network dynamics, we explain how homeostasis can simultaneously maintain the network's firing rate and sensitivity to small perturbations.

description: The advancement of South America’s agro-pastoral frontier has been widely linked to losses in biodiversity and tropical forests, with particular impacts on the Brazilian cerrado, the Atlantic Forest, and the Amazon. Here I consider an important, yet largely overlooked, driver of South America’s soybean expansion, namely the devaluation of local currencies against the US dollar in the late 1990s and early 2000s. Much interest has emerged in recent years over the environmental implications of soybean production in Brazil, with evidence of both direct incursions into moist tropical forest by soybean producers and of potential indirect effects, via the displacement of existing ranching operations. In this research I utilize historical trends in soybean prices, exchange rates, and cropland dedicated to soybean production in Bolivia, Paraguay, and Brazil to estimate the impact of currency devaluations on area of production. The results suggest that approximately 80,000km2, or 31 percent of the current extent of soybean production in these countries, emerged as a supply area response to the devaluation of local currencies in the late 1990s. The results also indicate that the more recent depreciation of the dollar and appreciation of the Brazilian real have counteracted a recent rise in global soybean prices, in the process sparing an estimated nearly 90,000 km2 from new cropland, 40,000 km2 of this in the Amazon alone.

description: At the time of the 1990s transition in Hungary from a socialist to a capitalist economy a process of land reform took place. The land of large state and collective farms was privatized. The average size of these newly privatized land parcels was not more than about 4 ha; even now, after some concentration, it is 4.6 ha for individuals. It is obvious that farms of such a size are not viable in a modern economy. However, it is fortunate that, on average, land tenure is much more concentrated than land ownership. Thus there are larger individual farms and commercial farms which rent land from those – mainly absent – landowners who own the small plots of agricultural land. Nevertheless, there are still many small farmers. Many of them use their land to grow vegetables and fruits. Most of the individual small farmers operate on a subsistence or semi-subsistence level. But there are some, about 20%, who produce exclusively for the market, and about 20% sell a part of their products. There are small farmers who are well-specialized for open-air or covered vegetable production, mainly on the Great Hungarian Plain. Yet it is not easy for them to sell their produce. Markets are increasingly dominated by hyper-markets, super-markets and discount chains. The chains need steady supplies and standard varieties of fruits and vegetables in large quantities throughout the whole year. Obviously, these requirements can only be fulfilled by those traders who dispose of large quantities of products. That is why these suppliers are mainly large domestic farms, big cooperatives and importers. If small farmers want to fit successfully into the supply chain, considerable cooperation will be needed.

description: Communication at millimeter wave (mmWave) frequencies is one of the main novelties introduced in the 5th generation (5G) of cellular networks. The opportunities and challenges associated with such high frequencies have stimulated a number of studies that rely on simulation for the evaluation of the proposed solutions. The accuracy of simulations largely depends on that of the channel model, but popular channel models for mmWaves, such as the Spatial Channel Models (SCMs), have high computational complexity and limit the scalability of the scenarios. This paper profiles the implementation of a widely-used SCM model for mmWave frequencies, and proposes a simplified version of the 3GPP SCM that reduces the computation time by up to 12.5 times while providing essentially the same distributions of several metrics, such as the Signal-to-Interference-plus-Noise Ratio (SINR) in large scale scenarios. We also give insights on the use cases in which using a simplified model can still yield valid results.

description: We propose a cavity based laser cooling and trapping scheme, providing tight confinement and cooling to very low temperatures, without degradation at high particle densities. A bidirectionally pumped ring cavity builds up a resonantly enhanced optical standing wave which acts to confine polarizable particles in deep potential wells. The particle localization yields a coupling of the degenerate travelling wave modes via coherent photon redistribution. This induces a splitting of the cavity resonances with a high frequency component, that is tuned to the anti-Stokes Raman sideband of the particles oscillating in the potential wells, yielding cooling due to excess anti-Stokes scattering. Tight confinement in the optical lattice together with the prediction, that more than 50% of the trapped particles can be cooled into the motional ground state, promise high phase space densities.

description: [Objectives] To explore the problem of “secondary desertification” caused by coal mining subsidence in sandy area and its control countermeasures. [Methods] The collapse fissure changes, vegetation displacement and tilt, dry sand layer and wind erosion/aeolian deposit rate of the edge, middle and basin of subsidence area were studied in detail. [Results] The width and density of fissures at the edge of subsidence area were the smallest, followed by those in the center, and the width and density of fissures in the basin of the subsidence area were the greatest, while the staggering and surface damage showed the opposite trend. The average displacement length of vegetation in the subsidence area reached 60 cm, the slope was 5.67-28.63, and the maximum wind erosion/aeolian deposit at the trunk roots was -30.52 cm/+25.41 cm, most serious at the edge of subsidence. The changes in displacement length and slope of vegetation were positively linearly correlated with the height and surface damage of collapse fissures. The thickness of dry land layer at the edge of the subsidence area reached 14 cm, 4-6 cm greater than that of the control, and the thickness of dry land layer in the middle and basin of the subsidence area was both about 11 cm, 1-4 cm greater than that of non-subsidence area. The wind erosion rate at the edge of the subsidence area was up to 83.34%, followed by that (52.06%) in the middle. The aeolian deposit rate in the subsidence basin was 51.84%. [Conclusions] The subsidence edge has the strongest impact on the sandy geomorphology and vegetation habitat, and is a key area for ecological restoration. It is recommended that the coal mining subsidence should be treated in a timely manner to avoid the occurrence of “secondary desertification”.

description: In this minireview we present the main results regarding the transport properties of stochastic movement with relocations to known positions. To do so, we formulate the problem in a general manner to see several cases extensively studied during the last years as particular situations within a framework of random walks with memory. We focus on (i) stochastic motion with resets to its initial position followed by a waiting period, and (ii) diffusive motion with memory-driven relocations to previously visited positions. For both of them we show how the overall transport regime may be actively modified by the details of the relocation mechanism.

description: Direct potable reuse (DPR) can improve reliability of water supplies by generating drinking water from wastewater, but communities have consistently opposed DPR more than other forms of reuse. Using interview data regarding DPR projects in five inland communities, this study fills gaps in the literature with an analysis of factors influencing acceptance of DPR. While scholars have recommended public processes used to implement non-potable and indirect potable reuse projects, there is little-to-no documentation about whether and how they have been used to implement DPR projects. Further, previous research has focused on large coastal cities. Counter to previous recommendations, we found minimal public deliberation of reuse options and public education/outreach occurring post-project conception. Findings suggest that direct experience with water scarcity, community smallness, and governance strongly influence DPR acceptance. With few DPR facilities worldwide, this new knowledge is useful to water planners who are interested in the feasibility of DPR in inland areas.

description: The topic of this paper is ozone smog or tropospheric ozone pollution and the assessment of one aspect of this problem: impacts on agricultural crops. However, the techniques and their problems are applicable to a wide range of impacts from materials damages to human health effects. In addition, the methods explained have been applied to agricultural damages related to both acid deposition (see Adams and McCarl, 1985a) and global climate change (Adams et al., 1988). The concentration here is on the estimation of the tangible benefits from policies 10 reduce tropospheric ozone concentrations.

description: Background: Functional trait-based approaches have been used to identify patterns of plant species diversity and composition related to environmental variability/changes. Bryophytes are rapidly affected by perturbations and thus their traits and distribution are expected to show well-defined relationships with environmental variability. Aim: To quantify the impacts of fragmentation on the diversity and structure of epiphytic bryophytes to vertical and horizontal environmental gradients in an Atlantic Forest remnant. Methods: Six functional traits related to water relations and light tolerance were recorded and one of them, the leaf lobule area in liverworts, was selected for morphometric measurements along the gradients analysed. Functional diversity and composition metrics of bryophytes along gradients were compared. Results: Functional diversity changed little along the vertical and horizontal gradients. Conversely, the functional composition of traits changed markedly. Traits related to water storage, such as the presence and area of lobules, and to protection against excess light incidence, such as dark pigments, were more numerous in the canopy and at the fragment edge. Conclusions: Functional composition is more correlated with the vertical and horizontal gradients than functional diversity. The lobule of liverworts stood out as the most relevant trait to explain the adaptive strategies of bryophytes.

description: This study proposes a framework of multilevel governing networks to analyse issues of multiple-use common-pool resource management in a complex socio-ecological system. By exploring the case study of the Golden Corridor Program in Yunlin, Taiwan, we found that self-governance at the community level is a partial way to govern multiple-use common-pool resources. Farmland here is facing the impact of land subsidence, and the high-speed rail construction has overweighted the surface. Although the Golden Corridor Program attempts to mitigate this effect of land subsidence on rail traffic safety through rewards for water-saving farming activities for farmers, the implementation lacks the intensive vertical integration and horizontal connections required to promote the collaborative platform among stakeholders. Local farmers still care about agricultural revenue. Thus, the loose self-governing capacity cannot generate institutional collective actions to improve the agri-environment here. The premature multilevel governing network has caused the governance failure to regulate this multiple-use common-pool resource.

Cicindela antatsima var. fotsy alluaud (1913: 495)

description: Synonym. Cicindela antatsima var. fotsy Alluaud (1913: 495). Synonymy by Horn (1934: 19).
 Type material. Syntype male of C. antatsima, labeled “ Madagascar (Sud)/Bassin du Mandraré/ Alluaud 1900 44” (DEIC, examined); Syntype female of C. antatsima var. fotsy, labeled “Mananpatra” (DEIC, examined).
 Diagnosis. Length 10.5-12.5 mm. Dorsal coloration as shown in Figures 1, 2. The extensive white coloration on the elytra separates this species from sympatric species of Chaetodera and Lophyra. It is most closely related to the Madagascan C. perrieri, from which it may be distinguished by the elytral color characteristics mentioned in the key to species (the elytral white areas are broadly expanded in C. antatsima, covering much of the disc, whereas the white areas on the elytra of C. perrieri are less extensive and tend to form alternating bands with the dark ground coloration).
 Notes. Horn (1934) and Olsoufieff (1934) considered this species to be a regional variant or subspecies of C. perrieri, while Jeannel (1946) treated these two taxa as separate species. Based on the specimens examined for this study, I concur with Jeannel’s assessment. The differences in color pattern between C. antatsima (Figure 1-2) and C. perrieri (Figure 3-4), although subtle, appear to be consistent among the specimens available for study. I was unable to find any specimens that represented intermediate forms that might be expected if subspecific variation was involved. I confirm that C. antatsima var. fotsy is conspecific with C. antatsima based on examination of the relevant type specimens. Specimens identified as C. antatsima var. fotsy in collections are individuals of C. antatsima in which the dark markings of the elytra are especially reduced.
 Material examined. MADAGASCAR: Ambositra (1 female, DEIC); Ampandrandava (1 male, 1 female, DEIC); Beroroha (1 male, DEIC); Manampatra (1 male, 1 female, DEIC); Mandrare, I.1933 (1 female, DEIC), 1933 (1 female, DEIC); Morondava, III.1931 (1 female, DEIC); Plateau de l’Andray – Reg. d’Ambovombe (1 male, DEIC); Tamatave, 9.IV.1920 (1 female, DEIC); Tananarive (1 male, DEIC), XII.1919 (2 males, CMNH).

Bayesian Estimation for Land Surface Temperature Retrieval: The Nuisance of Emissivities

description: An approach to the remote sensing of land surface temperature is developed using the methods of Bayesian inference. The starting point is the maximum entropy estimate for the posterior distribution of radiance in multiple bands. In order to convert this quantity to an estimator for surface temperature and emissivity with Bayes' theorem, it is necessary to obtain the joint prior probability for surface temperature and emissivity, given available prior knowledge. The requirement that any pair of distinct observers be able to relate their descriptions of radiance under arbitrary Lorentz transformations uniquely determines the prior probability. Perhaps surprisingly, surface temperature acts as a scale parameter, while emissivity acts as a location parameter, giving the prior probability P(T,emissivity|K)=const./T dT d(emissivity). Given this result, it is a simple matter to construct estimators for surface temperature and emssivity. Monte Carlo simulations of land surface temeprature retrieval in selected MODIS bands are presented as examples of the utility of the approach.

description: A method to implement the many-body Green function formalism in the GW approximation for infinite non periodic systems is presented. It is suitable to treat systems of known ``asymptotic'' properties which enter as boundary conditions, while the effects of the lower symmetry are restricted to regions of finite volume. For example, it can be applied to surfaces or localized impurities. We illustrate the method with a study of the surface of semi-infinite jellium. We report the dielectric function, the effective potential and the electronic self-energy discussing the effects produced by the screening and by the charge density profile near the surface.
