description: We present updated results of a high-resolution, magnitude limited (Ks<12 mag) imaging survey of nearby low-mass M6.0-M7.5 field stars. The observations were carried out using adaptive optics at the Gemini North, VLT, Keck II, and Subaru telescopes. Our sample of 36 stars consists predominantly of nearby (<30 pc) field stars, 5 of which we have resolved as binaries. Two of the binary systems, 2MASSI J0429184-312356 and 2MASSI J1847034+552243, are presented here for the first time. All 5 discovered binary systems have separations between 0.08"-0.53" (2-9 AU) with similar mass ratios (q>0.8, delta Ks < 1 mag). This result supports the hypothesis that wide (a>20 AU) very low-mass (M_tot<0.19 M_sun) binary systems are rare. The projected semimajor axis distribution of these systems peak at ~ 5 AU and we report a sensitivity-corrected binary fraction of 9% (-3%, +4%) for stars with primaries of spectral type M6.0-M7.5 with separations >3 AU and mass ratios q>0.6. Within these instrumental sensitivities, these results support the overall trend that both the semimajor axis distribution and binary fraction are a function of the mass of the primary star and decrease with decreasing primary mass. These observations provide important constraints for low-mass binary star formation theories.

description: We point out a new configuration in the Witten-Sakai-Sugimoto model, allowing baryons in the pointlike approximation to coexist with fundamental quarks. The resulting phase is a holographic realization of quarkyonic matter, which is predicted to occur in QCD at a large number of colors, and possibly plays a role in real-world QCD as well. We find that holographic quarkyonic matter is chirally symmetric and that, for large baryon chemical potentials, it is energetically preferred over pure nuclear matter and over pure quark matter. The zero-temperature transition from nuclear matter to the quarkyonic phase is of first order in the chiral limit and for a realistic pion mass. For pion masses far beyond the physical point we observe a quark-hadron continuity due to the presence of quarkyonic matter.

subject: Tobit model

description: In 2005, 30% of the Flemish farms faced a manure excess, while at aggregated level still 9.7% of the emission rights were unused. This means that, despite the various possibilities, Flemish farmers do not succeed in an effective exchange of manure between farms. In current paper is shown how inorganic fertilizer use influences the use and exchange of organic nitrogen. Because of the mutual interdependency between organic and inorganic nitrogen emission rights (or quota), inorganic nitrogen use limits the emission rights for organic nitrogen. Utilisation of these emission rights are analysed as a trade-offs choice between plant productivity (use of inorganic nitrogen) and manure disposal, as the major abatement alternative of manure production. Farmers still prefer inorganic fertilizers because of their effect on plant productivity and income. However, by changing the quota rent of organic nitrogen, the fertilization behaviour can be influenced. A higher quota rent of organic nitrogen would increase the use of manure. This trade-off behaviour seriously influences effectiveness of policies. When the objective is to lower the total nitrogen use, a mere reduction of organic quota can partially be counteracted by a higher inorganic nitrogen use. When the objective is to better spread the manure, increasing the quota rent for deficit farms will increase their acceptance of manure.

description: We continue the study of the effects of a strong magnetic field on the temperature distribution in the crust of a magnetized neutron star (NS) and its impact on the observable surface temperature. Extending the approach initiated in Geppert et al.(2004), we consider more complex and, hence, more realistic, magnetic field structures but still restrict ourselves to axisymmetric configurations. We put special emphasis on the heat blanketing effect of a toroidal field component. We show that asymmetric temperature distributions can occur and a crustal field consisting of dipolar poloidal and toroidal components will cause one polar spot to be larger than the opposing one. These two warm regions can be separated by an extended cold equatorial belt. We present an internal magnetic field structure which can explain both the X-ray and optical spectra of the isolated NS RXJ 1856-3754. We investigate the effects of the resulting surface temperature profiles on the observable lightcurve which an isolated thermally emitting NS would produce for different field geometries. The lightcurves will be both qualitatively (deviations from sinusoidal shape) and quantitatively (larger pulsed fraction for the same observational geometry) different from those of a NS with an isothermal crust. This opens the possibility to determine the interna} magnetic field strengths and structures in NSs by modeling their X-ray lightcurves and spectra. The striking similarities of our model calculations with the observed spectra and pulse profiles of isolated thermally emitting NSs is an indication for the existence of strong magnetic field components maintained by crustal currents.

description: Structural Equation Modelling (SEM) offers a theoretical basis for developing an understanding of the relationships between attitudes and behaviour. This paper imposes the SEM framework to a compulsory regulation which focuses on reducing diffuse water pollution, namely Nitrate Vulnerable Zones (NVZ). We use a data set collected through a farm survey within NVZs in Scotland in 2007. The model includes six latent variables expressing farmers’ nitrate reducing behaviour, nitrate reducing and profit maximizing behavioural propensities and the underlying determining factors, namely attitude (risk perception) and socio-economic latent variables (access to information and stocking density). The results indicate that the model has an adequate fit to the data and access to information is the strongest determinant of farmers’ nitrate reducing behaviour.

description: Collinear double-pulse seeding of the High-Gain Harmonic Generation (HGHG) process in a free-electron laser (FEL) is a promising approach to facilitate various coherent nonlinear spectroscopy schemes in the extreme ultraviolet (XUV) spectral range. However, in collinear arrangements using a single nonlinear medium, temporally overlapping seed pulses may introduce nonlinear mixing signals that compromise the experiment at short time delays. Here, we investigate these effects in detail by extending the analysis described in a recent publication (Wituschek et al., Nat. Commun., 11, 883, 2020). High-order fringe-resolved autocorrelation and wave-packet interferometry experiments at photon energies > $23\,$eV are performed, accompanied by numerical simulations. It turns out that both the autocorrelation and the wave-packet interferometry data are very sensitive to saturation effects and can thus be used to characterize saturation in the HGHG process. Our results further imply that time-resolved spectroscopy experiments are feasible even for time delays smaller than the seed pulse duration.

Exposure based durability of FRP strengthened concrete

Publisher: name: University of British Columbia
Year: 2009

description: Deteriorated concrete structures is a current problem facing Civil and Structural Engineers. Current repair techniques include replacement of the structure and or costly and expensive retrofits. . Current research is focusing on using Fiber Reinforced Plastics (FRPs) as a possible retrofit material. This study focuses on the durability issues surround and FRP techniques pioneered at the University of British Columbia. An FRP comprised of short glass fibers (GFRP) and polyester resins is sprayed on the tensile face of the deteriorated concrete. Early tests show that this has tremendous potential to be a cost effective method of retrofitting concrete structures. In order to further develop this material as an effective repair technique additional study on the durability of the material in neutral and high pH aqueous solutions at different exposure periods, with and with out pre stress on the concrete/FRP interface, was required. 72 concrete beams strengthened with GFRP and subject to different environmental exposures and concrete/FRP bond stress. The effect of exposure and bond pre stress is evaluated to determine the durability issues related to the use of GFRP as a concrete strengthening material. Study results are also used to provide analysis of the concrete/FRP bond. Based on the results of this study, recommendations regarding future study and the future use of GFRP as concrete strengthening material are made.

description: Non-point source pollution is notoriously difficult to asses. A relevant example is mineral emissions in the Netherlands. Since the mid 1980s the Dutch government has sought to reduce emissions through a wide variety of measures, the effect of which in turn is monitored using modeling techniques. This paper presents the current generation of mineral emission models from agriculture based on microsimulation of farms in combination with a spatial equilibrium model for the dispersion of manure from excess regions with high livestock intensities within the country to areas with low livestock intensities. The micro-simulation approach retains the richness in the heterogeneity of farm household decision making that are the core cause of the difficulty of assessing non-point source pollution, while using the best available data to track corresponding pollution. Using scenario analysis we are able to assess the possible effects of further tightening of agro-environmental policy.

description: In this paper we study second order non-linear periodic systems driven by the ordinary vector $p$-Laplacian with a non-smooth, locally Lipschitz potential function. Our approach is variational and it is based on the non-smooth critical point theory. We prove existence and multiplicity results under general growth conditions on the potential function. Then we establish the existence of non-trivial homoclinic (to zero) solutions. Our theorem appears to be the first such result (even for smooth problems) for systems monitored by the $p$-Laplacian. In the last section of the paper we examine the scalar \hbox{non-linear} and semilinear problem. Our approach uses a generalized Landesman--Lazer type condition which generalizes previous ones used in the literature. Also for the semilinear case the problem is at resonance at any eigenvalue.

Using very high quality transistors with tunable electron densities we measure m* in single, high mobility specimens over a wide range of r_s (6 to 0.8). Toward low-densities we observe a rapid increase of m* by as much as 40%. For 2>r_s>0.8 the mass values fall ~10% below the band mass of GaAs. Numerical calculations are in qualitative agreement with our data but differ considerably in detail.

description: We show that the Lorentz-Dirac equation is not an unavoidable consequence of energy-momentum conservation for a point charge. What follows solely from conservation laws is a less restrictive equation already obtained by Honig and Szamosi. The latter is not properly an equation of motion because, as it contains an extra scalar variable, it does not determine the future evolution of the charge. We show that a supplementary constitutive relation can be added so that the motion is determined and free from the troubles that are customary in Lorentz-Dirac equation, i. e. preacceleration and runaways.

description: This paper measures the contribution of innovations in total factor productivity(TFP) of organic olive farmers. By constructing an innovation variable instead of the use of a time trend, technical change is replaced by technical difference and TFP growth becomes TFP difference. Primary cross section data on organic olive enterprises from a Greek region is used in the application of the restricted frontier profit function. Farmers are classified into groups according to their innovative ‘profile’. TFP difference among consecutive innovation groups is decomposed into technical difference and adjustment in innovativeness effects. Furthermore, efficiency differences among innovation groups are estimated. Results indicate that more innovative farmers perform better than less innovative ones regarding TFP and efficiency scores. Adoption of innovations has a positive contribution in the reduction of inefficiency and profit-loss. The rate of technical difference is always positive in the formulation of TFP difference whereas the adjustment in innovativeness effects varies among the innovation groups. Finally, high-tech capital is more or less under-utilized, regardless of the innovation group.

description: The limit relations for the partial derivatives of the two-electron atomic wave functions at the two-particle coalescence lines have been obtained numerically using accurate CFHHM wave functions. The asymptotic solutions of the proper two-electron Schrodinger equation have been derived for both electron-nucleus and electron-electron coalescence. It is shown that the solutions for the electron-nucleus coalescence correspond to the ground and singly excited bound states, including triplet ones. The proper solutions at small distances $R$ from the triple coalescence point were presented as the second order expansion on R and lnR. The vanishing of the Fock's logarithmic terms at the electron-nucleus coalescence line was revealed in the frame of this expansion, unlike the case of electron-electron coalescence. On the basis of the obtained boundary solutions the approximate wave function corresponding to both coalescence lines have been proposed in the two-exponential form with no variational parameters.

description: Ex-ante impact assessment of agricultural, environmental, and rural policies has become an integral part of political decision making processes in the EU. While there is a large variety of agrienvironmental modelling tools available to analyse likely social, economic, and environmental impacts of these policies, scientifically well-founded ex-ante policy assessment tools capturing the institutional dimension are still missing. In this paper, we introduce a formalised procedure for modelling – ex-ante – institutional aspects for policy implementation: the ‘Procedure for Institutional Compatibility Assessment’ (PICA). PICA has been designed as an explorative, yet formalised methodology that enables policy makers to identify at an early stage potential institutional incompatibilities. After providing a brief overview of relevant approaches for policy assessment we elaborate on the four distinct steps of PICA and use a core element of the EU Nitrate Directive to illustrate its function.

description: Monte Carlo simulation has been performed in the planar P(_{2}) and P(_{4}) models to investigate the effects of the suppression of topological defects on the phase transition exhibited by these models. Suppression of the 1/2-defects on the square plaquettes in the P(_{2}) model leads to complete elimination of the phase transition observed in this model. However in the P(_{4}) model, on suppressing the single 1/2-defects on square plaquettes, the otherwise first order phase transition changes to a second order one which occurs at a higher temperature and this is due to presence of large number of 1/2-pair defects which are left within the square plaquettes. When we suppressed these charges too, complete elimination of phase transition was observed.

description: This paper evaluated diversified rural tourism activities from the perspectives of economic viability and endogenous utilization of rural resources and investigated labour productivity. First, we presented a conceptual framework on how to evaluate economic viability and the endogenous mobilization of rural resources. Second, we empirically evaluated economic viability, the supply shift effect of endogenous utilization of rural resources and labour productivity with regard to rural tourism. The main findings are as follows. First, examination of the three main activities, i.e. accommodation, restaurant operation and direct selling of farm products, showed that both full-time and part-time labour input contribute more effectively to better sales than such labour for farm experience services, which means that these activities are viable whereas other activities that provide farming experience services did not yet clearly show evidence of a viable farm business. Second, we could not confirm the supply shift effect of endogenous innovative use of rural resources. Overall, it was evaluated that rural tourism in this country is undersupplied at a social optimal level. In the long run, institutional conditions for market formation and management skills for endogenous innovation in utilization of rural resources should be more intensely developed as a part of rural resource management policy.

title: Isotopic, chemical, and crowdsourcing studies of selected water cycle components in arid environments
Creators: name: Michelsen, Nils
Publisher: name: UNSPECIFIED
Year: 2021

description: This cumulative thesis comprises five studies (four published, one submitted). The investigations either deal with specific aspects of Saudi Arabia’s water cycle or have a methodological character and the developed methods are particularly useful for arid environments. The first study addresses Riyadh rainfall. Besides major ion analyses, isotope analyses were conducted to calculate a precipitation-weighted Local Meteoric Water Line – a crucial, but hitherto missing reference for past and future groundwater isotope studies. The second investigation focuses on the next element of the water cycle – the unsaturated zone. Stable isotope fingerprints of sand dune pore waters and meteorological data were used in an isotope model to constrain rain events leading to deep infiltration into dune sands. Interestingly, the derived original (i.e., pre-evaporation) isotopic signatures were not represented in the data set on rainfall (see above) – probably due to the temporally limited nature of the latter. This observation calls for a long-term monitoring effort targeting the isotopic signature of precipitation in Riyadh and elsewhere in Saudi Arabia. To go beyond the somewhat generic call for more data, concrete advice on which type of cumulative rain sampler to use for such an endeavor is needed. As post-sampling evaporation has to be minimized, several established and new rain collector designs were tested in a laboratory oven. In this experiment, the Tube-dip-in-water collector with pressure equilibration tube proved to be a reliable and contamination-free option. Building on this knowledge, an automatic counterpart was designed in a fourth study. The microcontroller-based device enables timer-actuated integral rain sampling. The simple low-cost collector is robust and effectively minimizes post-sampling evaporation from the bottles, and the associated isotope fractionation. The excellent performance of the device during an extensive evaporation experiment in a laboratory oven suggests that even multi-week field deployments in warm climates are feasible. The fifth study deals with shallow groundwater. To reconstruct an unexpected water level rise in a Saudi Arabian cave, a crowdsourcing approach was applied. Chronologically sorted YouTube videos recorded in the cave were screened for suitable reference points (e.g., cave graffiti) that appear in several videos. Then, the distances between these points and the water level were visually estimated and their changes were traced over time. The acquired data helped to identify the likely cause of the piezometric changes – two nearby lakes formed from treated sewage effluent. Hopefully, the outlined findings can contribute to a better understanding of the hydrogeological system in Saudi Arabia and can help to identify promising paths for future research. The utilized methods might also be of value for other arid areas.
Signals of sneutrino-antisneutrino mixing in an $e^- γ$ collider in anomaly-mediated supersymmetry breaking

description: Sneutrino-antisneutrino mixing occurs in a supersymmetric model where neutrinos have nonzero Majorana masses. This can lead to the sneutrino decaying into a final state with a "wrong-sign charged lepton". Hence, in an $e^- γ$ collider, the signal of the associated production of an electron-sneutrino and the lighter chargino and their subsequent decays can be $e^- γ\to e^+ {\tilde τ}_1^- {\tilde τ}_1^- + \mpT$ where the ${\tilde τ}_1$s are long-lived and can produce heavily ionizing charged tracks. This signal is free of any Standard Model background and the supersymmetric backgrounds are small. Such a signal can be experimentally observable under certain conditions which are possible to obtain in an anomaly-mediated supersymmetry breaking scenario. Information on a particular combination of the neutrino masses and mixing angles can also be extracted through the observation of this signal. Possible modifications in the signal event and the accompanying Standard Model background have been discussed when the ${\tilde τ}_1$s decay promptly.

description: As a contribution to valuing the outputs of multifunctional agriculture, we report three new meta analyses estimating value functions for agricultural conservation program impacts on water quality, wetlands, and upland habitat and open space. As is often the case in valuation, where methods have yet to be standardized, the data sets are relatively small and noisy. With a clear objective of benefits transfer, we seek robust parameter estimates for key RHS variables, even at the cost of some loss of goodness of fit. We present our estimated full equations, and benefits transfer values calculated from equations estimated after backward elimination of insignificant variables, and offer a rationale for this approach to benefits transfer.

description: We report on the magnetoconductivity of quasi two-dimensional electron systems in inversion layers on p-type InAs single crystals. In low magnetic fields pronounced features of weak localization and antilocalization are observed. They are almost perfectly described by the theory of Iordanskii, Lyanda-Geller and Pikus. This allows us to determine the spin splitting and the Rashba parameter of the ground electric subband as a function of the electron density.

description: Using the most recent available data, this paper assesses who is likely to benefit, in the short-term, from the implementation of the CAP in Romania. Particularly, it focuses on the distributional impacts of the new form of agricultural subsidies under the CAP, i.e. SAPS and CNDP, identifying the main gainers and losers. Preliminary results reveal a highly uneven distribution of subsidies across farms, with the very large-scale ones, particularly those specialised in so-called “energy” crops, benefiting most from the flat rate direct aid. As a result, the existing gap between Romanian low-income and high-income farms will become larger, with those most vulnerable hardly benefiting from the introduction of (national and EU) direct payments.

description: In spite of progress in securing Vehicular Communication (VC) systems, there is no consensus on how to distribute Certificate Revocation Lists (CRLs). The main challenges lie exactly in (i) crafting an efficient and timely distribution of CRLs for numerous anonymous credentials, pseudonyms, (ii) maintaining strong privacy for vehicles prior to revocation events, even with honest-but-curious system entities, (iii) and catering to computation and communication constraints of on-board units with intermittent connectivity to the infrastructure. Relying on peers to distribute the CRLs is a double-edged sword: abusive peers could "pollute" the process, thus degrading the timely CRLs distribution. In this paper, we propose a vehicle-centric solution that addresses all these challenges and thus closes a gap in the literature. Our scheme radically reduces CRL distribution overhead: each vehicle receives CRLs corresponding only to its region of operation and its actual trip duration. Moreover, a "fingerprint" of CRL 'pieces' is attached to a subset of (verifiable) pseudonyms for fast CRL 'piece' validation (while mitigating resource depletion attacks abusing the CRL distribution). Our experimental evaluation shows that our scheme is efficient, scalable, dependable, and practical: with no more than 25 KB/s of traffic load, the latest CRL can be delivered to 95% of the vehicles in a region (15 x 15 KM) within 15s, i.e., more than 40 times faster than the state-of-the-art. Overall, our scheme is a comprehensive solution that complements standards and can catalyze the deployment of secure and privacy-protecting VC systems.

description: We study finite dimensional vector spaces over fields of elliptic functions equipped with two commuting aotomorphisms σand τinduced by isogenies of relatively prime orders. We give a structure theorem for such objects, that reveals a connection to the classification of vector bundles on elliptic curves by Atiyah. As an application we prove an elliptic analogue of a conjecture of Loxton and van der Poorten which has been recently proved by Adamczewski and Bell.

Exact summation of vertex corrections to the penetration depth in d-wave superconductors

description: A variety of experiments suggest that in the cuprates, the low-energy superconducting quasiparticles undergo forward scattering from extended impurity potentials. We argue that when such potentials dominate the scattering, the penetration depth may be computed in a simple zero-angle scattering approximation (ZSA), in which the vertex corrections to the Meissner effect may be summed exactly. We find a remarkably simple relationship between the normal fluid density and the quasiparticle density of states of the disordered system which holds for every realization of the disorder. We expect this result to be relevant to the $ab$-plane penetration depth in high-purity single crystals of underdoped YBCO.

description: We present a performance analysis of compact monolithic optomechanical inertial sensors that describes their key fundamental limits and overall acceleration noise floor. Performance simulations for low frequency gravity-sensitive inertial sensors show attainable acceleration noise floors of the order of 10^-11 ms^-2/rtHz. Furthermore, from our performance models, we determine the optimization criteria in our sensor designs, sensitivity, and bandwidth trade space. We conducted characterization measurements of these compact mechanical resonators, demonstrating mQ-products at levels of 250kg, which highlight their exquisite acceleration sensitivity.

description: We study the time evolution of the test scalar and electromagnetic fields perturbations in configurations of phantom wormholes surrounded by dark energy with state parameter $ω< -1$. We observe obvious signals of echoes reflecting wormholes properties and disclose the physical reasons behind such phenomena. In particular, we find that the dark energy equation of state has a clear imprint in echoes in wave perturbations. When $ω$ approaches the phantom divide $ω=-1$ from below, the delay time of echoes becomes longer. The echo of gravitational wave is likely to be detected in the near future, the signature of the dark energy equation of state in the echo spectrum can serve as a local measurement of the dark energy.

description: Early diagnosis of diabetic retinopathy for treatment of the disease has been failing to reach diabetic people living in rural areas. Shortage of trained ophthalmologists, limited availability of healthcare centers, and expensiveness of diagnostic equipment are among the reasons. Although many deep learning-based automatic diagnosis of diabetic retinopathy techniques have been implemented in the literature, these methods still fail to provide a point-of-care diagnosis. This raises the need for an independent diagnostic of diabetic retinopathy that can be used by a non-expert. Recently the usage of smartphones has been increasing across the world. Automated diagnoses of diabetic retinopathy can be deployed on smartphones in order to provide an instant diagnosis to diabetic people residing in remote areas. In this paper, inception based convolutional neural network and binary decision tree-based ensemble of classifiers have been proposed and implemented to detect and classify diabetic retinopathy. The proposed method was further imported into a smartphone application for mobile-based classification, which provides an offline and automatic system for diagnosis of diabetic retinopathy.

description: Lactate acts as an energy substrate and a signaling molecule to modulate neuronal functions such as excitability, plasticity and long-term memory formation. Lactate is known to regulate the NMDA receptor (NMDAR) activity through a NADH-dependent pathway. This effect leads to a modulation of synaptic plasticity-related gene expression. We have now observed that lactate potentiates NMDAR response by increasing the peak NMDAR currents (INMDAR) and prolonging the decay time. These effects are sensitive to Ifenprodil (GluN2B antagonist), but not to PEAQX (GluN2A antagonist), suggesting that lactate increases the contribution of GluN2B subunit to the increased NMDAR response. The lactate-mediated increase in peak INMDAR requires uptake of lactate into neurons and is blocked by inhibitors of lactate dehydrogenase, an enzyme that converts lactate into pyruvate with a concomitant rise in the NADH/NAD+ ratio. Compared to intracellular delivery, bath application of reducing agent Dithiothreitol (DTT) enhanced the lactate-mediated increase in peak INMDAR in an additive manner. In contrast, both bath and intracellular applications of the oxidizing agent 5,5-dithiobis-(2-nitrobenzoic acid) (DTNB) decrease the INMDAR potentiation by lactate. These indicate that lactate may act intracellularly through a redox-mediated regulation of NMDAR function. Using a thiol-trapping approach, we found that both n-acetylcysteine amide (NACA) and lactate increase the levels of reduced thiol (-SH) in GluN2B, possibly through modification of intracellular redox state. Lactate enhancement of the NMDAR response is dependent on Ca2+/calmodulin-dependent protein kinase II (CaMKII), a kinase known to bind to synaptic NMDAR. Lactate-induced INMDAR potentiation is abolished when the binding of GluN2B to CaMKII kinase domain is impaired. Together, these results suggest that lactate boosts synaptic plasticity through a redox-mediated regulation of GluN2B-containing NMDAR which may promotes the interaction of CaMKII with GluN2B to further enhance the NMDAR response.
