description: We investigate the relation between the characteristics of the circumnuclear stellar population and both the galaxy morphology and the presence of close companions for a sample of 35 Seyfert 2 nuclei. Fifteen galaxies present unambiguous signatures of recent episodes of star formation within $\approx$300 pc from the nucleus. When we relate this property with the Hubble type of the host galaxy, we find that the incidence of recent circumnuclear star formation increases along the Hubble sequence, and seems to be larger than in non-Seyfert galaxies for the early Hubble types S0 and Sa, but similar to that in non-Seyfert galaxies for later Hubble types. Both in early-type and late-type Seyferts, the presence of recent star-formation is related to the galaxy morphology in the inner few kiloparsecs, as observed in HST images through the filter F606W by Malkan et al., who has assigned a late ``inner Hubble type'' to most Seyfert 2s with recent nuclear star-formation. This new classification is due to the presence of dust lanes and spiral structures in the inner region. The presence of recent star formation in Seyfert 2 nuclei is also related to interactions: among the 13 galaxies of the sample with close companions or in mergers, 9 have recent star formation in the nucleus. These correlations between the presence of companions, inner morphology and the incidence of recent star formation suggest an evolutionary scenario in which the interaction is responsible for sending gas inwards which both feeds the AGN and triggers star-formation. The starburst then fades with time and the composite Seyfert 2 + Starburst nucleus evolves to a ``pure'' Seyfert 2 nucleus with an old stellar population.

description: The goal of this article is to discuss controllability properties for an abstract linear system of the form $y' = Ay + Bu$ under some additional linear projection constraints on the control $u$ or / and on the controlled trajectory $y$. In particular, we discuss the possibility of imposing the linear projections of the controlled trajectory and of the control, in the context of approximate controllability, exact controllability and null-controllability. As it turns out, in all these settings, for being able to impose linear projection constraints on the trajectory and on the control, we will strongly rely on a unique continuation property for the adjoint system which, to our knowledge, has not been identified so far, and which does not seem classical. We shall therefore provide several instances in which this unique continuation property can be checked.

description: Leptin is an important adipokine and plays a vital role in animals. However, the role of leptin in the autophagic response of pig fibroblast cells (PFCs) has not been fully elucidated. In this study, we investigated the relationship between leptin and autophagy as well as underlying molecular basis. We found that PFCs treated with EBSS could secrete leptin, and the leptin concentration in the supernatant of leptin transgenic PFCs was higher than that of WT PFCs. We found an increase in LC3-II protein level and a decrease in p62 protein level in treated leptin transgenic PFCs compared with treated WT PFCs. Meanwhile, we observed an increase of autophagosomes by transmission electron microscopy and an enhancement of the accumulation of LC3 puncta in the cytoplasm of treated leptin transgenic PFCs, and these effects were further augmented by Baf A1 treatment. Furthermore, we detected the expression levels of 7 autophagy signaling pathway genes and 17 autophagy-related (ATG) genes by q-PCR. We found that between the two types of EBSS-treated cells 3 genes expression pattern were significantly different among the 7 autophagy signaling pathway genes and 8 genes expression pattern were significantly differernt among the ATG genes. These results indicated that leptin may promote autophagy and involving the downregulation of FOXO1 and LMNA genes via an unknown pathway which causes the upregulation of the 4 genes and the downregulation of 4 genes.
Measuring the Cosmic Equation of State with Counts of Galaxies II: Error Budget for the DEEP2 Redshift Survey

description: In a previous paper, we described a new variant on the classical dN/dz test which could be performed using upcoming redshift surveys. By observing the velocity function of galaxies rather than their luminosity function, it is possible to avoid many of the uncertainties of galaxy evolution while employing a directly measurable quantity. We previously assumed that counting statistics would dominate the errors in this method. Here, we present the results of including cosmic variance and determine the impact of systematic effects on application of this test to the upcoming DEEP2 Redshift Survey. For DEEP2, cosmic variance should yield errors roughly twice those predicted from Poisson statistics. Through Monte Carlo simulations we find that if the functional form, but not the strength, of any of the major systematic effects (baryonic infall, velocity errors, and incompleteness) is known, the systematic may successfully be corrected for using the observed velocity function, leaving a much smaller residual error. The total uncertainty from systematics is comparable to that from cosmic variance, but correlated amongst redshift bins. We find that DEEP2 can provide a much more precise measurement of the cosmic equation of state parameter w than any available today, albeit weaker than some other proposed tests.

description: Some of the most prominent theoretical predictions of modern times, e.g., the Unruh effect, Hawking radiation, and gravity-assisted particle creation, are supported by the fact that various quantum constructs like particle content and vacuum fluctuations of a quantum field are observer-dependent. Despite being fundamental in nature, these predictions have not yet been experimentally verified because one needs extremely strong gravity (or acceleration) to bring them within the existing experimental resolution. In this Letter, we demonstrate that a post-Newtonian rotating atom inside a far-detuned cavity experiences strongly modified quantum fluctuations in the inertial vacuum. As a result, the emission rate of an excited atom gets enhanced significantly along with a shift in the emission spectrum due to the change in the quantum correlation under rotation. We propose an optomechanical setup that is capable of realizing such acceleration-induced particle creation with current technology. This provides a novel and potentially feasible experimental proposal for the direct detection of noninertial quantum field theoretic effects.

Quantum correction to the Kubo formula in closed mesoscopic systems

description: We study the energy dissipation rate in a mesoscopic system described by the parametrically-driven random-matrix Hamiltonian H[ϕ(t)] for the case of linear bias ϕ=vt. Evolution of the field ϕ(t) causes interlevel transitions leading to energy pumping, and also smears the discrete spectrum of the Hamiltonian. For sufficiently fast perturbation this smearing exceeds the mean level spacing and the dissipation rate is given by the Kubo formula. We calculate the quantum correction to the Kubo result that reveals the original discreteness of the energy spectrum. The first correction to the system viscosity scales proportional to v^{-2/3} in the orthogonal case and vanishes in the unitary case.

description: Wire rope used in cable logging, where a series of cables facilitate the extraction of timber on steep terrain, experiences high tensions that must be managed to ensure safety. Innovations change practices over time and double-hitch carriages, which allow trees to be extracted horizontally, are a recent example. This makes it feasible to harvest across terrain with limited deflection, increases the recovery of biomass, and potentially reduces high-dynamic load events associated with ground contact. In this study, a standard single-hitch carriage was compared against a new double-hitch carriage under controlled conditions. Tension was measured continuously and specific elements, such as tension when the carriage was at midspan, maximum tension at breakout and inhaul, and magnitude of cyclic tension during inhaul were identified, measured and compared against payload. While payload was similar in the treatments, the additional weight of the double-hitch carriage resulted in higher skyline tensions. In both treatments, payload and skyline tension when the carriage was at midspan were strongly correlated. Cyclic tension was reduced by the double-hitch carriage system. While a number of unique high-dynamic loads were identified that were not part of the normal extraction, they represented only 6% of the cycles and the maximum tension was similar to that experienced during break-out and inhaul. This study increased the understanding of skyline tension during logging operations and the effect of carriage type. It showed that, though tension often exceeds the safe working load of the cable, it does not exceed the endurance limit for a well-designed and operated system.

description: To ensure effective communication, it is crucial for a speaker to clearly convey the intended meaning while also being mindful of how they phrase their statements to avoid potentially offending the listener. When making requests, speakers often address these challenges by using 'indirect speech', as seen in examples like (1) "Can you open the window?" or (2) "Are you able to open the window?". Indirect requests, like (1) and (2), are considered to carry two types of meaning: literal meaning (inquiring about the listener's ability to perform an action) and directive meaning (asking the listener to perform the action), with variations in the extent to which (1) and (2) express these meanings. We introduce a probabilistic framework that models the speaker's choices between alternatives such as (1) and (2). The model can predict how these choices vary across different social parameters, highlighting the connection between differences in meaning and the selection of request alternatives.
Effect of shear-coupled grain boundary motion on coherent precipitation

description: We examine the interaction between precipitates and grain boundaries, which undergo shear-coupled motion. The elastic problem, emerging from grain boundary perturbations and an elastic mismatch strain induced by the precipitates, is analysed. The resulting free elastic energy contains interaction terms, which are derived numerically via the integration of the elastic energy density. The interaction of the shear-coupled grain boundary and the coherent precipitates leads to potential elastic energy reductions. Such a decrease of the elastic energy has implications on the grain boundary shape and also on the solubility limit near the grain boundary. By energy minimisation we are able to derive the grain boundary shape change analytically. We apply the results to the Fe-C system to predict the solubility limit change of cementite near an $α$-iron grain boundary.

description: We consider the permutation group algebra defined by Cameron and show that if the permutation group has no finite orbits, then no homogeneous element of degree one is a zero-divisor of the algebra. We proceed to make a conjecture which would show that the algebra is an integral domain if, in addition, the group is oligomorphic. We go on to show that this conjecture is true in certain special cases, including those of the form H Wr S and H Wr A, and show that in the oligormorphic case, the algebras corresponding to these special groups are polynomial algebras. In the H Wr A case, the algebra is related to the shuffle algebra of free Lie algebra theory. We finish by considering some integer sequences which arise from certain of these groups.

Bubbles or Convenience Yields? A Theoretical Explanation with Evidence from Technology Company Equity Carve-Outs

description: This paper offers an alternative explanation for what is typically referred to as an asset pricing bubble. We develop a model that formalizes the Cochrane (2002) convenience yield theory of technology company stocks to explain why a rational agent would buy an “overpriced” security. Agents have a desire to trade but short-sale restrictions and other frictions limit their trading strategies and enable prices of two similar securities to be different. Thus, divergent prices for similar securities can be sustained in a rational expectations equilibrium. The paper also provides empirical support for the model using a sample of 1996 - 2000 equity carve-outs.

Ochterus

description: Genus OCHTERUS Latreille
  Discussion.  — Ochterus species form two distinct ecological groups, those inhabiting horizontal littoral substrates of mud and sand along lowland lakes and rivers, and those occurring on vertical seeping rheocrenes and wet rocks in the highlands. The latter guild has radiated extensively in the mountains of New Guinea (Baehr, 1990b) and to a lesser extent in the Philippines (Gapud, 1981, 1995, 2003; Gapud & San Valentin, 1977), Sulawesi (Nieser & Chen, 1992, 1999), and the Greater Sunda Islands (Jaczewski, 1935; Baehr, 1990a; Nieser & Chen, 1992; Zettel & Lane, 2010); as shown below, certain continental Asian species also share this ecology. With the exception of widespread species such as O. marginatus, which occurs along the margins of ponds and rivers, ochterids tend to be poorly represented in collections, being active, agile insects which fly readily when disturbed and are challenging to capture. This, combined with their utilisation of frequently undersampled rheocrene habitats, means that they may often be overlooked by general collectors (Jaczewski, 1935). The species inhabiting rheocrenes are often best collected by applying a light pyrethrin fog and then capturing the insects thus slowed in their movements.
 As currently interpreted, four species of Ochteridae occur in Singapore and Peninsular Malaysia, three of which are newly described below. The key also includes two additional widespread species known from the Greater Sunda Islands that could also conceivably occur in the region under study (see Appendix 1 for an updated regional checklist of Ochterus species occurring in Southeast Asia and the Malay Archipelago).

description: The space-charge effect, due to the instantaneous emission of many electrons after the absorption of a single photons pulse, causes distortion in the photoelectron energy spectrum. Two calculation methods have been applied to simulate the expansion during a free flight of clouds of mono- and bi-energetic electrons generated by a high energy pulse of light and their results have been compared. The accuracy of a widely used tool, such as SIMION(R), in predicting the energy distortion caused by the space-charge has been tested and the reliability of its results is verified. Finally we used SIMION(R) to take into account the space-charge effects in the simulation of simple photoemission experiments with a time-of-flight analyzer.

description: The abundances of groups and clusters of galaxies are expected to have changed substantially since high redshift, with the strength of this evolution dependent upon fundamental cosmological parameters. Upcoming large redshift surveys of distant galaxies will make it possible to measure these quantities at z~1; when combined with the results of local redshift surveys currently underway, the evolution of cluster abundances may be determined. The DEEP2 Redshift Survey, planned to begin in Spring 2002, is particularly well-suited for this work because of the high spectroscopic resolution to be used; velocity dispersions of groups will be readily measurable. In this paper, we determine the constraints on dark energy models that counts of DEEP2 clusters should provide. We find that comparing cosmological models using the simultaneous distribution of clusters in both velocity dispersion and redshift yields significantly stronger constraints than the redshift distribution alone. The method can be made more powerful by employing a value of the fluctuation amplitude sigma_8 determined with upcoming techniques (external to DEEP2) that have no Omega_m degeneracy. The equation-of-state parameter for dark energy models, w=P/rho, can then be measured to ~0.1 from observations of clusters alone.

description: Full-time working within agriculture is now relatively uncommon; many farm households are still active in the off-farm labor markets, in and outside the local economy. This paper examines the impact of a portfolio of off-farm incomes on food consumption patterns using Working-Leser framework, under two-stage budgeting, to isolate the off-farm income effect from the pure expenditure elasticities. This is analyzed for rural farm households in transitional Albania. The results indicate that food at home consumption has a positive and inelastic association with offfarm wage income, whereas, the response food away from home consumption is positive and highly elastic. Remittances generate the opposite effect on food consumption both at home and away from home, leading to reduction of food consumption. A disaggregated analysis reveals that off-farm wage income increases households’ consumption of cereal-based foods at home; we find the opposite and significant effect for remittances. These findings should be of interest to policymakers in Albania, especially in designing poverty and nutrition programs.

description: The phenomenon of agricultural land conversion in Namlea subdistrict becomes a problem when the number of productive land is increasingly reduced and affects land availability for agricultural production. Research was conducted to describe the conversion of agricultural land and its utilization in Namlea subdistrict. The research site focuses on Namlea District Buru Regency with consideration of the availability of the number of agricultural land that is less than other districts in Buru Regency. The number of informant interviewed as many as 40 people consisting of land owners, farmers, business owners and village apparatus. Analytical techniques used to follow the
concept of Miles and Huberman where activities in the analysis of qualitative data are conducted interactively and continuously to find saturation in data processing. The results showed that the reduction of farmland in Namlea district was due to the conversion of land for various activities including housing and development of the Trade Center. In addition, the use of converted land is caused by the system of personal ownership that is secured by the Government through the right to building or proprietary rights but has not fully set the long-term oriented land utilization pattern

description: The cosmic infrared background records much of the radiant energy released by processes of structure formation that have occurred since the decoupling of matter and radiation following the Big Bang. In the past few years, data from the Cosmic Background Explorer mission provided the first measurements of this background, with additional constraints coming from studies of the attenuation of TeV gamma-rays. At the same time there has been rapid progress in resolving a significant fraction of this background with the deep galaxy counts at infrared wavelengths from the Infrared Space Observatory instruments and at submillimeter wavelengths from the Submillimeter Common User Bolometer Array instrument. This article reviews the measurements of the infrared background and sources contributing to it, and discusses the implications for past and present cosmic processes.

description: Changes in crop prices have encouraged farmers to consider alternatives, such as potential advanced bioenergy feedstocks, including energy beets. This paper employs an integrated biophysical, economic and GIS-based transportation model to examine the supply of beet-bioethanol from five sites in North Daktoa. The study finds that beet bioethanol could provide net benefits to farmers and ethanol producers in the state, under current market conditions, but only if the bioethanol plant site is carefully selected. More specifically, a 20,000,000 gallon ethanol plant in Valley City could have net returns of $436,049. This plant would acquire 760,000 tons of beets from around the plant site and further east toward the Red River Valley from 22,682 acres of cropland an average distance of 15.7 miles away. The average yield of the selected cropland is 33.5 tons/ac with average net farm returns of $26.09/acre above opportunity costs. Opportunity and transportation costs can substantially change the attractiveness of croplands for beet production. The current market opportunity presented by beet bioethanol at $1.50/gal ethanol is not particularly attractive, but as ethanol prices increase, this opportunity could become attractive at a number of sites throughout the state.

description: Construction and demolition (C&D) waste minimization is an important strategy for addressing waste management challenges. Generally, C&D waste minimization is a complex and open system involving various interrelated processes, elements and stakeholders. Previous studies have investigated internal factors of the system, but neglected effects of external factors and interactions between internal and external factors. Therefore, this paper aims to investigate China’s C&D waste minimization system from the perspectives of integrity and dynamics. Based on the dissipative structure theory, the paper examines whether China’s C&D waste minimization system is a dissipative structure, given that a dissipative structure system can transform itself from disordered state to ordered state spontaneously through interactions among the inherent subsystems and elements involved. Firstly, 28 factors influencing waste minimization are identified. Secondly, the Brusselator model and entropy methods are adopted for empirical analysis with the data collected by questionnaire survey. The findings reveal that China’s current C&D waste minimization system is not a dissipative structure; consequently, the development of the system cannot form a macroscopic stable and orderly structure through self-organization. Accordingly, suggestions are proposed to effectively promote the C&D waste minimization system toward a dissipative structure. The findings are expected to enhance the C&D waste minimization system through forming a dissipative structure and consequently achieving orderly and coordinated system development.

Gelastocoridae

description: Family GELASTOCORIDAE Kirkaldy    Discussion.  — Gelastocoridae, or “ toad bugs ”, are easily recognised among the nepomorphan families by their rough and sculptured body surface, large eyes, presence of ocelli, the broad and flap-like labrum, four-segmented antennae lacking finger-like projections, enlarged raptorial fore femora, the tarsal formula of 1-2-3, unequal development of the claws on the forelegs, and asymmetrical genitalia with the right paramere large and often elaborated, and the left reduced or absent. As noted earlier, a number of these character states, as well as a riparian ecology, are shared with the Ochteridae. Among the local assemblage of Southeast Asian species, characters of particular use in individual species discrimination include the arrangement of tubercles on the head, the shape of the pronotum, and the shape of the male right paramere (Figs. 36, 38). In contrast to Ochteridae, dorsal coloration is not a particularly useful species-specific character, and is in any case often obscured by mud and dirt, which covers many mature specimens and further serves to camouflage living individuals in the field.
 The Gelastocoridae are also similar to the previously treated Ochteridae in being a pantropical family with two distinct foci of species radiation in the Neotropical and Melanesian regions, and limited species richness elsewhere. Three genera are currently recognised: the Neotropical Gelastocoris and Montandonius, and the widespread Nerthra (see Todd, 1955). Only the latter genus occurs in Singapore and Malaysia. The gelastocorid species occurring on continental Southeast Asia and the proximal Greater Sunda Islands were recently treated by Kment & Jindra (2008), and the reader is referred to that work for a more comprehensive treatement of the Asian fauna. The family is probably more diverse and widespread in tropical Asia than is currently understood, with many of the species occurring in this region being known from very limited material. Pitfall trapping is a particularly effective method for collecting gelastocorids, and more concerted effort in this regard, particularly in areas of relatively undisturbed rainforest, has the potential to yield valuable insights related to the distribution and ecological associations of these unusual insects.

The Optical Luminosity Function of Virialized Systems

description: We determine the optical luminosity function of virialized systems over the full range of density enhancements, from single galaxies to clusters of galaxies. The analysis is based on galaxy systems identified from the Nearby Optical Galaxy (NOG) sample, which is the largest, all-sky catalog of objectively- identified bound objects presently available. We find that the B-band luminosity function of systems is insensitive to the choice of the group-finding algorithms and is well described, over the absolute-magnitude range -24.5 < M < -18.5, by a Schechter function with alpha=-1.4, Mstar=-23.1 and phistar=4.8 10^{-4} Mpc^-3 The characteristic luminosity of virialized systems is ~3 times brighter than that of the luminosity function of galaxies. Our results show that half of the luminosity of the universe is generated in systems with L<2.9 Lstar and that 10% of the overall luminosity density is supplied by systems with L>30 Lstar. We find a significant environmental dependence in the luminosity function of systems, in the sense that overdense regions, as measured on scales of 5 Mpc, preferentially host brighter, and presumably more massive, virialized systems.

description: This study examines the extent to which heterogeneous environmental attitudes influence recreational demand in a river basin and the valuation of recreational benefits. We first employed a latent class analysis to reveal two distinct classes of respondents that differ in their environmental attitudes despite representing similar demographic characteristics. We then estimated a recreational demand model conditional on respondent’s latent class membership after controlling for the probabilistic nature of the membership classification. We found that environmental attitudes directly influence consumer recreational demand and valuation. Ignoring preference heterogeneity leads to overestimation of the recreational benefits.
Quasiparticles as Detector of Topological Quantum Phase Transitions

description: A number of tools have been developed to detect topological phase transitions in strongly correlated quantum systems. They apply under different conditions, but do not cover the full range of many-body models. It is hence desirable to further expand the toolbox. Here, we propose to use quasiparticle properties to detect quantum phase transitions. The approach is independent from the choice of boundary conditions, and it does not assume a particular lattice structure. The probe is hence suitable for, e.g., fractals and quasicrystals. The method requires that one can reliably create quasiparticles in the considered systems. In the simplest cases, this can be done by a pinning potential, while it is less straightforward in more complicated systems. We apply the method to several rather different examples, including one that cannot be handled by the commonly used probes, and in all the cases we find that the numerical costs are low. This is so, because a simple property, such as the charge of the anyons, is sufficient to detect the phase transition point. For some of the examples, this allows us to study larger systems and/or further parameter values compared to previous studies.

description: The Cold Dark Matter model describes successfully our Universe on large scales, as has been verified by a wide range of observations. Nevertheless, in the last years, and especially with the advances in numerical simulations, a number of apparent inconsistencies arose between what is observed and what the CDM model predicts on small scales. In this work, the current status of observations on galactic and subgalactic scales is reviewed. Furthermore, theory and observation are brought together in order to reveal the nature of the inconsistencies and, consequently, to reveal their severity. Lastly, the progress towards the resolution of each one of these conflicts is briefly reviewed.

description: The sorghum industry is threatened by a new invasive pest, the sugarcane aphid (SCA), capable of causing substantial damage to crop production and local economies. Little work has been conducted to assess and better understand the economic implications of the SCA outbreak. The objective of this study was to estimate the economic impact of SCA in the Lower Rio Grande Valley (LRGV), Texas, where 11.5% of the state production is located. Local producers were surveyed to gather detailed information about yearly crop yields, crop acreage, insecticide application decisions, and management and production practices. Collected data were used to estimate the reduction in growers’ profit associated to the SCA infestation, as well as the monetary value of the prevented loss attributed to control efforts. Sorghum industry losses were then used to assess the overall economic impact of the SCA outbreak in the LRGV economy in terms of output, value-added, labor income and employment effects.
