description: This work investigates midwave infrared Type-II InAs/GaSb superlattice (SL) grown by molecular beam epitaxy on GaSb substrate. In order to compensate the natural tensile strain of the InAs layers, two different shutter sequences have been explored during the growth. The first one consists of growing an intentional InSb layer at both interfaces (namely GaSb-on-InAs and InAs-on-GaSb interfaces) by migration enhanced epitaxy while the second uses the antimony-for-arsenic exchange to promote an InSb-like interface at the GaSb-on-InAs interface. SLs obtained via both methods are compared in terms of structural, morphological and optical properties by means of high-resolution x-ray diffraction, atomic force microscopy and photoluminescence spectroscopy. By using the second method, we obtained a nearly strain-compensated SL on GaSb with a full width at half maximum of 56 arcsec for the first-order SL satellite peak. Relatively smooth surface has been achieved with a root mean square value of about 0.19 nm on a 2 $μm$ x 2 $μm$ scan area. Finally, a p-i-n device structure having a cut-off wavelength of 5.15 $μm$ at 77K has been demonstrated with a dark-current level of $8.3 * 10^{-8} A/cm^2$ at -50 mV and a residual carrier concentration of $9.7 * 10^{14} cm^{-3}$, comparable to the state-of-the-art.

description: Corporate Social Responsibility (CSR) or Corporate Sustainability reporting is a relatively new phenomenon in Hungary. As the external pressure from the civil society, public authorities and the media has so far been fairly low, this important corporate activity emerged only at the beginning of the last decade. In spite of this, several pioneering companies have started to publish information on its environmental and social performance in recent years. CSR and sustainability reports are seen increasingly as strategic documents that offer a balanced, objective, and comprehensive assessment of a firm’s non-financial performance. In 2008 and 2009, more than a third of the 100 largest companies reported on their non-financial results (most of them were GRI based reports). In 2010, sixty-one organisations published a report about their non- financial performance, and 22 of these for only the first time. The aim of this paper is to present recent attempts to use indicators in CSR and sustainability reports. On the basis of a detailed review of 70 CSR/sustainability reports published during the last 9 years in Hungary, an analysis was made on the performance indicators appearing in the reports. The motivations of indicator selection processes was analysed and the intended roles of indicator set in communication and strategy design was presented. The significance of and limits to the proposed indicators was discussed.

description: The notion of sustainability is the basis for our future possibilities. Local sustainability, in the centre of which can be found the livable settlement, is especially important in rural areas.Without developing rural areas, there is no developing society. The growth of the Earth’s population and the world economy has already surpassed the carrying capacity of this planet which may result in an “overshoot and collapse”. This can still be prevented today. The population of towns and cities is rapidly increasing. Urbanization is a very fast process, even in Hungary. In large cities with millions of inhabitants crime and lumpen lifestyle pose huge problems. However, the bases of a successful economy are morals and a puritan lifestyle, which so far have characterized rural villages. 70% of the poor and needy live in rural areas in the developing countries and agriculture provides livelihood for 40% of the world’s population. The International Assessment of Agricultural Knowledge, Science and Technology for Development (IAASTD) was established in 2002 by FAO and theWorld Bank to learn more about the role of agricultural science and technology. After the positive decision some comprehensive summaries were made on all the related topics with the participation of 400 scientists. The assessment provided many lessons to learn and at the 2008 closing sessions in Johannesburg, the reports were accepted and it was proved that rural areas have a significant role in providing adequate means of earning a livelihood.

description: We investigate the backreaction equations for an acoustic black hole formed in a Laval nozzle under the assumption that the motion of the fluid is one-dimensional. The solution in the near-horizon region shows that as phonons are (thermally) radiated the sonic horizon shrinks and the temperature decreases. This contrasts with the behaviour of Schwarzschild black holes, and is similar to what happens in the evaporation of (near-extremal) Reissner-Nordstrom black holes (i.e. infinite evaporation time). Finally, by appropriate boundary conditions the solution is extended in both the asymptotic regions of the nozzle.

description: We theoretically analyze the effect of density/refractive-index gradients on the measurement precision of Volumetric Particle Tracking Velocimetry (V-PTV) and Background Oriented Schlieren (BOS) experiments by deriving the Cramer-Rao lower bound (CRLB) for the 2D centroid estimation process. A model is derived for the diffraction limited image of a particle or dot viewed through a medium containing density gradients that includes the effect of various experimental parameters such as the particle depth, viewing direction and f-number. Using the model we show that non-linearities in the density gradient field lead to blurring of the particle/dot image. This blurring amplifies the effect of image noise on the centroid estimation process, leading to an increase in the CRLB and a decrease in the measurement precision. The ratio of position uncertainties of a dot in the reference and gradient images is a function of the ratio of the dot diameters and dot intensities. We term this parameter the Amplification Ratio (AR), and we propose a methodology for estimating the position uncertainties in tracking-based BOS measurements. The theoretical predictions of the particle/dot position estimation variance from the CRLB are compared to ray tracing simulations with good agreement. The uncertainty amplification is also demonstrated on experimental BOS images of flow induced by a spark discharge, where we show that regions of high amplification ratio correspond to regions of density gradients. This analysis elucidates the dependence of the position error on density and refractive-index gradient induced distortion parameters, provides a methodology for accounting its effect on uncertainty quantification and provides a framework for optimizing experiment design.

description: We study the unitarity bounds of the scattering amplitudes in the extra dimensional gauge theory where the gauge symmetry is broken by the boundary condition. The estimation of the amplitude of the diagram including four massive gauge bosons in the external lines shows that the asymptotic power behavior of the amplitude is canceled. The calculation will be done in the 5 dimensional standard model and the SU(5) grand unified theory, whose 5th dimensional coordinate is compactified on $S^1/Z_2$. The broken gauge theories through the orbifolding preserve the unitarity at high energies similarly to the broken gauge theories where the gauge bosons obtain their masses through the Higgs mechanism. We show that the contributions of the Kaluza-Klein states play a crucial role in conserving the unitarity.

The crystals were hexagon platelets of typical size 3x3x0.1 mm. Three of the five (A1g+E1g+3E2g) Raman active phonons were unambiguously identified at 458 (E1g), 494(E2g) and 574 (A1g) cm-1. The spectra from ab and ac surfaces differ significantly and provide evidence that within hours after preparation the ac surface, unlike the ab one, is strongly disordered. Within several days the disorder extends over the ab surface too.

description: The investment decisions of small-scale farmers in developing countries are conditioned by their financial environment. Binding credit market constraints and incomplete insurance can reduce investment in activities with high expected profits. We conducted several experiments in northern Ghana in which farmers were randomly assigned to receive cash grants, grants of or opportunities to purchase rainfall index insurance, or a combination of the two. Demand for index insurance is strong, and insurance leads to significantly larger agricultural investment and riskier production choices in agriculture. The salient constraint to farmer investment is uninsured risk: when provided with insurance against the primary catastrophic risk they face, farmers are able to find resources to increase expenditure on their farms. Demand for insurance in subsequent years is strongly increasing in a farmer’s own receipt of insurance payouts, and with the receipt of payouts by others in the farmer’s social network. Both investment patterns and the demand for index insurance are consistent with the presence of important basis risk associated with the index insurance, and with imperfect trust that promised payouts will be delivered.

description: The North Dakota University System consists of the North Dakota University System Office and 11 college campuses located throughout the state. In addition to the 11 main campuses, numerous other university facilities, centers, and offices are located throughout the state. Institutions of higher education have an economic effect in their respective areas and across the state as those institutions acquire inputs, purchase services, and provide for payroll and employment at both the local and state level. North Dakota University System expenditures include general fund sources (e.g., state appropriated monies) and non-general fund sources (i.e., grants, contracts, donations). North Dakota University System in-state expenditures for fiscal year (FY) 2011 comprise the direct economic impact or ‘first round effects.’ The North Dakota Input-Output Model was used to estimate the secondary economic effects as those direct effects (i.e., expenditures) are circulated and re-spent in the economy. The model estimates the changes in gross business volume (gross receipts) for all sectors of an economy and is used to provide key economic indicators such as retail trade activity, economy-wide personal income, gross business volume, secondary employment, and state-level tax receipts. Key measures of the economic contribution of the North Dakota University System in FY2011 include: • Direct economic impacts (expenditures) of $1.2 billion, of which $817 million were expenditures from non-general fund sources • Direct expenditures from general and non-general funds created a gross business volume of $3.5 billion, which included $832 million in retail trade activity and $1.4 billion in economy-wide personal income • Economic output in the retail trade sector would generate $38.5 million in sales and use tax collections, and economy-wide personal income of $1.4 billion would generate about $20.7 million in individual income tax collections in North Dakota • Direct employment by the North Dakota University System was 11,438 positions (excluding student jobs). • Secondary (indirect and induced) employment resulting from the business activity generated by the North Dakota University System was estimated at 11,474 jobs • Enrollment in the 11 member universities and colleges in the Fall of 2010 (which more closely aligns with FY2011) was equal to 38,899 full-time equivalent students • Student living expenses were estimated at $392 million and were in addition to institution spending • Increased business activity generated by student spending was estimated at $974 million, which included $440 million in retail trade activity and $236 million of economy-wide personal income and would support about 2,000 secondary jobs.

Modelling Orebody Structures: Block Merging Algorithms and Block Model Spatial Restructuring Strategies Given Mesh Surfaces of Geological Boundaries

description: This paper describes a framework for capturing geological structures in a 3D block model and improving its spatial fidelity given new mesh surfaces. Using surfaces that represent geological boundaries, the objectives are to identify areas where refinement is needed, increase spatial resolution to minimize surface approximation error, reduce redundancy to increase the compactness of the model and identify the geological domain on a block-by-block basis. These objectives are fulfilled by four system components which perform block-surface overlap detection, spatial structure decomposition, sub-blocks consolidation and block tagging, respectively. The main contributions are a coordinate-ascent merging algorithm and a flexible architecture for updating the spatial structure of a block model when given multiple surfaces, which emphasizes the ability to selectively retain or modify previously assigned block labels. The techniques employed include block-surface intersection analysis based on the separable axis theorem and ray-tracing for establishing the location of blocks relative to surfaces. To demonstrate the robustness and applicability of the proposed block merging strategy in a more narrow setting, it is used to reduce block fragmentation in an existing model where surfaces are not given and the minimum block size is fixed. To obtain further insight, a systematic comparison with octree subblocking subsequently illustrates the inherent constraints of dyadic hierarchical decomposition and the importance of inter-scale merging. The results show the proposed method produces merged blocks with less extreme aspect ratios and is highly amenable to parallel processing. The overall framework is applicable to orebody modelling given geological boundaries, and 3D segmentation more generally, where there is a need to delineate spatial regions using mesh surfaces within a block model.

description: The in-plane resistivity has been measured in $La_{2-x}Sr_xCuO_4$ (LSxCO) superconducting thin films of underdoped ($x=0.10,0.12$), optimally-doped ($x=0.15$) and overdoped ($x=0.20,0.25$) compositions. These films were grown on (100)SrTiO$_3$ substrates, and have about 150 nm thickness. The in-plane conductivity induced by superconducting fluctuations above the superconducting transition (the so-called in-plane paraconductivity, $Δσ_{ab}$) was extracted from these data in the reduced-temperature range $10^{-2}\lsimε\equiv\ln(T/\Tc)\lsim1$. Such a $Δσ_{ab}(ε)$ was then analyzed in terms of the mean-field--like Gaussian-Ginzburg-Landau (GGL) approach extended to the high-$ε$ region by means of the introduction of a total-energy cutoff, which takes into account both the kinetic energy and the quantum localization energy of each fluctuating mode. Our results strongly suggest that at all temperatures above Tc, including the high reduced-temperature region, the doping mainly affects in LSxCO thin films the normal-state properties and that its influence on the superconducting fluctuations is relatively moderate: Even in the high-$ε$ region, the in-plane paraconductivity is found to be independent of the opening of a pseudogap in the normal state of the underdoped films.

description: Appropriate management and policy responses for dryland salinity vary depending on biophysical and socio-economic conditions, and on the resources in question (water resources, biodiversity, infrastructure, agricultural land, salt-affected land). In this paper we present a framework for selecting responses consistent with economic and scientific evidence. Current policies rely heavily on communication, education and payment of incentives, but a broader range of responses is needed, including engineering works for key infrastructure, selective use of regulation/permits to limit planting of perennials in certain areas of high-water-yielding catchments, and development of improved salinity management technologies for farmers. We are over-relying on incentives and communication, which are only likely to be cost-effective in certain situations.

description: High-performance concrete is currently receiving a lot ofattention in research due to its properties and wide range of uses. This paperis focused on HPC, where the optimization of the mixture is specificallyaddressed regarding the technological solution of construction. The firstreference variant uses an approach that is suitable for processing at aconcrete plant. An alternative solution is intended for the processing of dryconcrete mixture, which can be bagged and the concrete itself produced atthe construction site. The paper deals with the comparison of two HPC basedon the same input and quantity of raw materials except for thesuperplasticizer. The purpose is to determine the HPC behaviour andproperties of a reference mixture with conventional liquid superplasticizersand a mixture using powdered superplasticizer. The experimental programincludes tests of the mechanical properties of compressive strength andflexural strength, where growth was monitored during the first 28 days, splittensile strength and velocity of ultrasound wave. Attention is also paid tofresh mixture tests. Although in the long term the mechanical properties oftested materials were very similar, the difference was determined during thefirst few days and weeks of hardening, when in mixture using powderedsuperplasticizer strength characteristics were increasing noticeably slowerthan in case of referential mixture.

A systematic functional analytic construction is provided. Various examples of fragmentation kernels illustrating the theory are given and an open problem is mentioned.

The dynamic parameters of the model are fixed by using the experimental data for those of the baryon octet. Sum rules for the magnetic moments are derived. We found that the magnetic moments of the baryon antidecuplet have opposite signs to their charges. The magnetic moments of the neutral baryon antidecuplet turn out to be compatible with zero.

With empirical coupling constants and cutoff parameters in the form factors, sum of their cross sections at center-of-mass energy of 11.5 GeV is about 1 $μ$b and is comparable to measured inclusive cross section for charmed hadron production from proton-proton reactions. The cross section decreases to about 1 nb at 40 MeV above threshold.

description: Manually annotating complex scene point cloud datasets is both costly and error-prone. To reduce the reliance on labeled data, a new model called SnapshotNet is proposed as a self-supervised feature learning approach, which directly works on the unlabeled point cloud data of a complex 3D scene. The SnapshotNet pipeline includes three stages. In the snapshot capturing stage, snapshots, which are defined as local collections of points, are sampled from the point cloud scene. A snapshot could be a view of a local 3D scan directly captured from the real scene, or a virtual view of such from a large 3D point cloud dataset. Snapshots could also be sampled at different sampling rates or fields of view (FOVs), thus multi-FOV snapshots, to capture scale information from the scene. In the feature learning stage, a new pre-text task called multi-FOV contrasting is proposed to recognize whether two snapshots are from the same object or not, within the same FOV or across different FOVs. Snapshots go through two self-supervised learning steps: the contrastive learning step with both part and scale contrasting, followed by a snapshot clustering step to extract higher level semantic features. Then a weakly-supervised segmentation stage is implemented by first training a standard SVM classifier on the learned features with a small fraction of labeled snapshots. The trained SVM is used to predict labels for input snapshots and predicted labels are converted into point-wise label assignments for semantic segmentation of the entire scene using a voting procedure. The experiments are conducted on the Semantic3D dataset and the results have shown that the proposed method is capable of learning effective features from snapshots of complex scene data without any labels. Moreover, the proposed method has shown advantages when comparing to the SOA method on weakly-supervised point cloud semantic segmentation.

description: Improving smallholder welfare in the rural sectors of developing countries requires improving access to both input and product markets. Success, however, in developing sustainable and mutually beneficial links between smallholders and agribusiness has been variable. Two recent ACIAR studies concluded that there may be more to linking smallholders with the agribusiness sector than individual smallholder characteristics. This paper hypothesizes that social capital influences the ability of individual smallholders to take advantage of emerging agribusiness opportunities. It outlines a project proposed by the authors that aims to test this hypothesis and examine the potential for social capital to help alleviate rural poverty while maintaining social and environmental balance.

description: This paper explores price integration between wholesale and retail prices of live reef food fish, a highvalue export fishery supplied by nearly 20 countries in the Asia-Pacific region with demand centred in Hong Kong. Cointegration analysis is used to test for relationships between wholesale and retail prices in demand countries for live reef fish species in aggregate and then by species. Results indicate that wholesale and retail prices of live reef fish species are cointegrated and form part of the same market. An analysis of price integration between wholesale supply and wholesale demand prices is undertaken using a high value reef fish exported to Hong Kong from Australia.

Neither the rock nor the hard place: using payment thresholds to balance the politics and the economics of emissions control

description: To maximise the economic benefits of tradable emission permits or emission taxes, while keeping these emission pricing mechanisms politically acceptable, requires the use of payment thresholds. There is no other way to avoid the "rock versus hard place" dilemma posed by the standard, polar forms of these pricing mechanisms that are generally discussed by economists, namely auctioned permits, free permits, or a pure tax. This means that in total, the government should auction permits only beyond some payment threshold, and should levy a tax on emissions only beyond a similar threshold. For full symmetry, the latter would mean treating emission taxes like tradable emission permits, with the tax threshold thus a de facto property right, though thresholds less like property rights can still be useful. The importance of a payment threshold is shown empirically for the case of global greenhouse gas abatement, where we use emission pricing to maximise welfare subject to a political constraint on the total control and revenue costs directly paid by emitters. This shows how using a payment threshold allows abatement to be much higher, and welfare to be higher, than with the standard forms of emission pricing.

description: Electromagnetic splittings for mesons and baryons are calculated in a formalism where the constituent quarks are considered as dressed quasiparticles. The electromagnetic interaction, which contains coulomb, contact, and hyperfine terms, is folded with the quark electrical density. Two different types of strong potentials are considered. Numerical treatment is done very carefully and several approximations are discussed in detail. Our model contains only one free parameter and the agreement with experimental data is reasonable although it seems very difficult to obtain a perfect description in any case.

description: We report measurements of the thermal conductivity $κ$ on single crystalline CeRu$_4$Sn$_6$ in the temperature range between 80mK and 80K, along the main crystallographic directions. $κ$ is phonon-dominated in the whole temperature range and is found to be essentially isotropic. At low temperatures the data are well approximated by $κ\propto T^2$, which is attributed to a predominant scattering of phonons on electrons. We describe the data with a Callaway fit in the whole temperature range giving good agreement at low and high temperatures.

description: We study the problem of constructing a probability density in 2N-dimensional phase space which reproduces a given collection of $n$ joint probability distributions as marginals. Only distributions authorized by quantum mechanics, i.e. depending on a (complete) commuting set of $N$ variables, are considered. A diagrammatic or graph theoretic formulation of the problem is developed. We then exactly determine the set of ``admissible'' data, i.e. those types of data for which the problem always admits solutions. This is done in the case where the joint distributions originate from quantum mechanics as well as in the case where this constraint is not imposed. In particular, it is shown that a necessary (but not sufficient) condition for the existence of solutions is $n\leq N+1$. When the data are admissible and the quantum constraint is not imposed, the general solution for the phase space density is determined explicitly. For admissible data of a quantum origin, the general solution is given in certain (but not all) cases. In the remaining cases, only a subset of solutions is obtained.
