We also identify the most general cosmological models with compact space.

description: This study assesses the nature of networking between youth and agricultural policymakers – given youth disillusionment with agricultural livelihoods. Using the Malawi case, a mixed methods approach shows that first local government departments that are mandated to work on youth issues are the main hubs of information for youth in agriculture. The Ministry of Agriculture plays a secondary role. Second, the study shows that youth in agriculture have little or no direct interactions with each other. Therefore, youth remain on the periphery of agricultural policymaking and their role in shaping agricultural policy dialogue is negligible. This is attributable to both lack of a deliberate government policy to include the youth and lack of a unified youth platform. The onus is therefore on the youth to ensure that they are effectively engaged in agricultural policy dialogue. The study conclusions with policy recommendations relevant for countries with the ‘youth/agriculture’ problem like Malawi.

description: The "food vs. fuel" debate may be difficult to resolve without letting the data ’speak’. We investigate the short and long-run relationships between food and fuel prices. Our analysis spans the period 1989-2013, covering the lead-up to the 2007-08 price spike, the sharp downward movement in the aftermath, as well as the period thereafter. This provides a more complete picture of the interaction between agriculture and fuel markets. Our results indicate the existence of a long-run equilibrium relationship between the prices in these markets. A closer examination of the dynamics between ethanol and corn, soybean, and sugar prices shows that the corn-soybean linkage plays a key role in shaping the long-run relationship between food and fuel prices. Although ethanol prices Granger cause corn prices, no individual agricultural commodity Granger causes ethanol prices. However, corn and soybean as a single group has an impact on the ethanol market

description: To achieve a successful grasp, gripper attributes such as its geometry and kinematics play a role as important as the object geometry. The majority of previous work has focused on developing grasp methods that generalize over novel object geometry but are specific to a certain robot hand. We propose UniGrasp, an efficient data-driven grasp synthesis method that considers both the object geometry and gripper attributes as inputs. UniGrasp is based on a novel deep neural network architecture that selects sets of contact points from the input point cloud of the object. The proposed model is trained on a large dataset to produce contact points that are in force closure and reachable by the robot hand. By using contact points as output, we can transfer between a diverse set of multifingered robotic hands. Our model produces over 90% valid contact points in Top10 predictions in simulation and more than 90% successful grasps in real world experiments for various known two-fingered and three-fingered grippers. Our model also achieves 93%, 83% and 90% successful grasps in real world experiments for an unseen two-fingered gripper and two unseen multi-fingered anthropomorphic robotic hands.

description: Consumer preferences for labeled products are often assumed to be exogenous to the presence of labels. However, the label itself (and not the information on the label) can be interpreted as a noisy warning signal. We measure the impact of “Contains” labels and additional information about the labeled ingredients, treating preferences for labeled characteristics as endogenous. We find that for organic food shoppers, the “Contains” label absent additional information serves as a noisy warning signal leading them to overestimate the riskiness of consuming the product. Provision of additional information mitigates the large negative signaling effect of the label.

description: In the wake of the 2007/2008 international food crisis, public food reserve re-gained the attention of policy makers. However, they come at high economic and fiscal costs. On the other hand, the imperfect correlation of supply shocks across neighboring countries entails the potential to reduce regional market volatility through intra-regional trade integration and storage cooperation. In this chapter, optimal reserve levels are theoretical derived in order to assess costs and benefits from regional storage cooperation. The model is then applied to the West African region which is in the process of establishing a region-wide reserve. Accordingly, regional stocks under cooperation in an emergency reserve can be 40 percent less than without cooperation. Limited intra-regional trade reduces the need for stock releases significantly. Full market integration would diminish regional consumption variability to 3.4 percent, less than for every other individual West African country, but is not effective in dampening severe supply shortfalls. Cooperation in a stabilization reserve in addition to trade integration has only limited impact on consumption stability, and thus storage cooperation shall be restricted to an emergency reserve.

Further, these energies can be given in finite terms at specific temperatures associated with singular moduli of elliptic function theory. Some examples are listed and numbers given.

description: Methane and carbon dioxide produced in peatlands can be held temporarily in dissolved surface waters and accessible to aquatic plants. The primary peat building plant in northern peatlands, Sphagnum moss, grows in these dissolved carbon rich waters. Understanding Sphagnum carbon cycles is key for radiocarbon dating, peatland restoration, and modelling of methane release from warming peatlands globally. This combined surface and multi‐proxy palaeoenvironmental study challenges common assumptions about the dissolved gas cycling in this semi‐aquatic environment. The Sphagnum associated methanotrophic communities within the water filled hyaline cells have commonly been linked to unusual 13C‐depleted measurements of Sphagnum carbon isotope ratios. The distinctly 13C‐depleted methane dissolved in surface pool water is traced using isotopic analysis as it is oxidised and travels into the interstitial Sphagnum water, through to being photosynthetically captured in α‐cellulose that makes up living Sphagnum, and finally to the carbon stored in layers of peat. Evidence is presented of a carbon supply available to Sphagnum from both symbiotic methanotrophs and heterotrophs. Mass balance calculations showed that Sphagnum associated methanotrophic communities only contribute a small proportion of the carbon fixed by Sphagnum growing in wet environments despite significant local oxidation. Evidence is presented for the interstitial Sphagnum water, rich in dissolved carbon dioxide, often being bypassed in favour of the much faster diffusion of carbon dioxide through air. Combined Sphagnum δ13C and hopanoid biomarkers in core material showed evidence of a brief period of substantial methane uptake, however, it is proposed that these events are only detectable in rare instances whereby uptake is sustained for periods of months to years. This study has demonstrated that an evolving body of research regarding Sphagnum associated methanotrophs can be applicable in blanket bog habitats. In the context of methane emissions from peatlands globally, this study indicates that previous estimates of methane uptake by Sphagnum applied broadly in these landscapes would likely overestimates the true extent of this process. Nonetheless, the demonstration of methane oxidation to carbon dioxide in these recently restored sites indicates a resilience of Sphagnum associated methanotrophic community activity and further evidences of the value in Sphagnum reintroduction as a host for methane oxidising bacteria in degraded landscapes undergoing rewetting.

description: Recently the scaling laws describing the roughness development of fracture surfaces was proposed to be related to the macroscopic elastic energy released during crack propagation [Mor00]. On this basis, an energy-based asymptotic analysis allows to extend the link to the nominal strength of structures. We show that a Family-Vicsek scaling leads to the classical size effect of linear elastic fracture mechanics. On the contrary, in the case of an anomalous scaling, there is a smooth transition from the case of no size effect, for small structure sizes, to a power law size effect which appears weaker than the linear elastic fracture mechanics one, in the case of large sizes. This prediction is confirmed by fracture experiments on wood.

description: We model a regional grain reserve as a game of two countries that agree to pool together a fraction of their grain to cope with production risk, but that can also repudiate their obligations at any moment. The reserve can be operated as a “credit union” or an “insurance union”. We find that although risk sharing is more effective when production shocks are negatively correlated, the regional reserve is more sustainable when the correlation is positive. We also find that an “insurance” game can be more sustainable than a “credit” game.

 Diagnosis. This genus is erected for N. rotundipennis which shares similar structures of Bergrothista (head, antennae) but differs from this by its smaller size, ovate widely rounded abdomen, anterolateral angles of pronotum produced beyond collar; and by its granular surface of the body, its appendices without flat scales; and by the stridulatory file on vltg III which is larger and its surface finely striate without pegs, extending from the anterolateral angle to inner posterior angle of vltg III. Because the metathoracic scent gland canal is also well developed and visible, Neobergrothista n.gen should be placed in Mezirinae.
 Etymology. From>neo<(Greek) new and Bergrothista the closest related genus.

description: Purpose: To identify optimal classification methods for computed tomography (CT) radiomics-based preoperative prediction of clear cells renal cell carcinoma (ccRCC) grade. Methods and material: Seventy one ccRCC patients were included in the study. Three image preprocessing techniques (Laplacian of Gaussian, wavelet filter, and discretization of the intensity values) were applied on tumor volumes. In total, 2530 radiomics features (tumor shape and size, intensity statistics, and texture) were extracted from each segmented tumor volume. Univariate analysis was performed to assess the association of each feature with the histological condition. In the case of multivariate analysis, the following was implemented: three feature selection including the least absolute shrinkage and selection operator (LASSO), students t-test and minimum Redundancy Maximum Relevance (mRMR) algorithms. These selected features were then used to construct three classification models (SVM, random forest, and logistic regression) to discriminate the high from low-grade ccRCC at nephrectomy. Lastly, multivariate model performance was evaluated on the bootstrapped validation cohort using the area under receiver operating characteristic curve (AUC). Results: Univariate analysis demonstrated that among different image sets, 128 bin discretized images have statistically significant different (q-value < 0.05) texture parameters with a mean of AUC 0.74 (q-value < 0.05). The three ML-based classifier shows proficient discrimination of the high from low-grade ccRCC. The AUC was 0.78 in logistic regression, 0.62 in random forest, and 0.83 in SVM model, respectively. Conclusion: Radiomics features can be a useful and promising non-invasive method for preoperative evaluation of ccRCC Fuhrman grades. Key words: RCC, Radiomics, Machine Learning, Computed Tomography

The adelic generalization of the Hartle-Hawking proposal does not work in models with matter fields. p-Adic and adelic minisuperspace quantum cosmology is well defined as an ordinary application of p-adic and adelic quantum mechanics. It is illustrated by a few minisuperspace cosmological models in one, two and three minisuperspace dimensions. As a result of p-adic quantum effects and the adelic approach, these models exhibit some discreteness of the minisuperspace and cosmological constant. In particular, discreteness of the de Sitter space and its cosmological constant is emphasized.

description: The role of international agricultural research centers (IARCs) has long been a subject of discussion, often with emphasis that they should conduct research that produces international public goods (IPGs). However, centers still face a dilemma on how to balance between IPGs and location-specific work. This paper contributes to the development of principles by which they should position themselves. Transaction cost economics was applied to develop a framework, which is then illustrated with an empirical case study of legume research at the International Crops Research Institute for the Semi-Arid Tropics. A participatory mapping technique (Net-Map) was combined with key informant interviews in India, Malawi and Ethiopia. We find that IARCS play an important role in germplasm improvement, the field in which they have a comparative advantage. However, due to insufficient capacity of national systems, they also engage in downstream activities. This reduces incentives for governments and donors to overcome governance challenges.

description: Lack of ground-truth MR images impedes the common supervised training of neural networks for image reconstruction. To cope with this challenge, this paper leverages unpaired adversarial training for reconstruction networks, where the inputs are undersampled k-space and naively reconstructed images from one dataset, and the labels are high-quality images from another dataset. The reconstruction networks consist of a generator which suppresses the input image artifacts, and a discriminator using a pool of (unpaired) labels to adjust the reconstruction quality. The generator is an unrolled neural network -- a cascade of convolutional and data consistency layers. The discriminator is also a multilayer CNN that plays the role of a critic scoring the quality of reconstructed images based on the Wasserstein distance. Our experiments with knee MRI datasets demonstrate that the proposed unpaired training enables diagnostic-quality reconstruction when high-quality image labels are not available for the input types of interest, or when the amount of labels is small. In addition, our adversarial training scheme can achieve better image quality (as rated by expert radiologists) compared with the paired training schemes with pixel-wise loss.

The accuracy of our approach is gauged by detailed comparisons with Quantum Monte Carlo simulations. The negative pressure dependence of Tc and the existence of photoemission hot spots in electron-doped cuprate superconductors find their natural explanation within this approach.

description: A model of a voluntary "green" payment program is developed to control nitrate leaching and runoff from corn production in New York. The program achieves environmental goals through self-interested choices of farmers, grouped by the productive and environmental characteristics of soils. It considers randomness in prict}~, production, and environmental damage. Farmers are assumed to maximize expected utility subject to chance constraints on severe levels of nitrate contamination. This program compensates farmers for applying environmentally safe levels of nitrogen fertilizer. If information is symmetric, program participation conditions require that the post-policy expected utility is at least as large as pre-policy expected utility. Under asymmetric information payments must be set so that farmers in group i always prefer their own policy over group's policy. If information is symmetric, the two groups have separate optimal policies. If information is asymmetric, separate policies are optimal if, and only if, the group with higher marginal productivity of nitrogen can meet environmental standards more easily; otherwise only a single policy need be specified. An empirical application of the model to three New York farming regions is based on estimated yield and environmental damage relationships from New York soils data. Asymmetric information between producers and the government would impose a cost burden on society. Separate policies are specified for the two groups, and the cost of information is as high as $11 per acre. The group most susceptible to nitrate leaching and runoff receives a windfall benefit, but this group makes up only about 10% of the total corn acreage. Two alternative methods of defining environmental quality standards are examined. First, environmental standards impose relative (percentage) reductions from pre-policy levels of nitrate loss. The second method requires an absolute level of environmental quality. The optimal payments range from $1 to $28 per acre. Under relative standards, payments are highest in the region with the highest level of pre-policy environmental quality. This situation is reversed when absolute standards are imposed. At an aggregate level, the program payments would range from $0.5 million to $3.5 million over the regions combined, representing between 3% and 18% of total government payments received by farmers in the three regions in 1992. The effect of risk aversion on program payments depends on whether nitrogen fertilizer is a risk increasing or risk reducing input. For the New York case studied, nitrogen was a risk reducing input for the group with higher yielding soils, and a risk increasing input for the other. Higher levels of risk aversion increase payments for the first group and decrease payments for the second.

description: We apply several quantization schemes to simple versions of the Chinos game. Classically, for two players with one coin each, there is a symmetric stable strategy that allows each player to win half of the times on average. A partial quantization of the game (semiclassical) allows us to find a winning strategy for the second player, but it is unstable w.r.t. the classical strategy. However, in a fully quantum version of the game we find a winning strategy for the first player that is optimal: the symmetric classical situation is broken at the quantum level.

description: We propose the Galactic flare model for the origin of the X-ray gas in the Galactic halo. For this purpose, we examine the magnetic reconnection triggered by Parker instability (magnetic buoyancy instability), by performing the two-dimensional resistive numerical magnetohydrodynamic simulations. As a result of numerical simulations, the system evolves as following phases: Parker instability occurs in the Galactic disk. In the nonlinear phase of Parker instability, the magnetic loop inflates from the Galactic disk into the Galactic halo, and collides with the anti-parallel magnetic field, so that the current sheets are created in the Galactic halo. The tearing instability occurs, and creates the plasmoids (magnetic islands). Just after the plasmoid ejection, further current-sheet thinning occurs in the sheet, and the anomalous resistivity sets in. Petschek reconnection starts, and heats the gas quickly in the Galactic halo. It also creates the slow and fast shock regions in the Galactic halo. The magnetic field ($B\sim 3 μ$G), for example, can heat the gas ($n\sim 10^{-3}$ cm$^{-3}$) to temperature of $\sim 10^6$ K via the reconnection in the Galactic halo. The gas is accelerated to Alfvén velocity ($\sim 300$ km s$^{-1}$). Such high velocity jets are the evidence of the Galactic flare model we present in this paper, if the Doppler shift of the bipolar jet is detected in the Galactic halo.

 Loricula (Loricula) issykatensis Rosenzweig, 1995: 251. HT: ♀, KI, Kyrghyz Range, Issyk Ata Valley, 1400 m; ZMAS.
 Material examined. 1 ♂, China, Xinjiang, Yili, Guozigou, Dujiacun, 44°27’N, 81°10' E, 1912 m, N. Vinokurov leg. The specimen is kept in the Entomological Museum of China Agricultural University (Beijing).
 Remarks. This Central Asian mountainous species was described from Kyrghyzstan, where it inhabits litter under Juniperus semiglobosa and Picea schrenkiana (Rosenzweig, 1995). Our specimen was collected from lower brunches of the spruce species Picea schrenkiana in the Borohoro Range near Sailimu (Sairam-Nur) Lake at the altitude of 1912 m a.s.l. (Fig 1).
 Xinjiang occupies northwestern part of China and belongs to the Central Asian subregion of Sethian (Desert) Region of the Palaearctic (Konstantinov et al. 2009). The fauna of bugs of this territory still remained insufficiently studied. By our estimation, 6 species of microphysids occurring in adjoining territories of Middle Asia, Siberia and the Russian Far East might probably be found in northern China, especially in Xinjiang. These microphysids are the Euro-Siberian L. (Myrmedobia) exilis Fall. and L. (M.) distinguenda Reut., the South Siberian L. (Myrmedobia) asiatica Pér. and L. (Myrmericula) longiceps Vin. (mountainous, both on Altai Mts), the East-Siberian and Far Eastern L. (L.) pilosella Miy. L., and the Middle Asian L. (L.) kerzhneri Pér. (Kyrghyzstan).

description: Let us consider a $p$-adic Lie extension of a number field $K$ which fits into the setting of non-commutative Iwasawa theory formulated by Coates-Fukaya-Kato-Sujatha-Venjakob. For the first main result, we will prove the control theorem of Selmer group associated to a motive, which generalizes previous results by the second author and Greenberg. For the second main result, we prove the functional equation of the dual Selmer groups, which generalizes previous results by Greenberg, Perrin-Riou and Zabradi. Note that our proof of the functional equation is different from the proof of Zabradi even in the case where the Selmer group is associated to an elliptic curve. We also discuss the functional equation for the analytic $p$-adic $L$-functions and check the compatibility with the functional equation of the dual Selmer groups.

description: Up to now it has been impossible to find a realistic interpretation for the reduction process in relativistic quantum mechanics. The basic problem is the dependence of the states on the frame within which collapse takes place. A suitable use of the causal structure of the devices involved in the measurement process allows us to introduce a covariant notion for the collapse of quantum states.

Superconductor-to-Spin-Density-Wave Transition in Quasi-One-Dimensional Metals with Ising Anisotropy

description: We study a mechanism for superconductivity in quasi-one-dimensional materials with Ising anisotropy. In an isolated chain Ising anisotropy opens a spin gap; if inter-chain coupling is sufficiently weak, single particle hopping is suppressed and the physics of coupled chains is controlled by a competition between pair hopping and exchange interaction. Spin density wave and triplet superconductivity phases are found separated by a first order phase transition. For particular parameter values a second order transition described by SO(4) symmetry is found.

description: For any pair of quantum states (the hypotheses), the task of binary quantum hypotheses testing is to derive the tradeoff relation between the probability $p_{01}$ of rejecting the null hypothesis and $p_{10}$ of accepting the alternative hypothesis. The case when both hypotheses are explicitly given was solved in the pioneering work by Helstrom. Here, instead, for any given null hypothesis as a pure state, we consider the worst-case alternative hypothesis that maximizes $p_{10}$ under a constraint on the distinguishability of such hypotheses. Additionally, we restrict the optimization to separable measurements, in order to describe tests that are performed locally. The case $p_{01}=0$ has been recently studied under the name of "quantum state verification". We show that the problem can be cast as a semi-definite program (SDP). Then we study in detail the two-qubit case. A comprehensive study in parameter space is done by solving the SDP numerically. We also obtain analytical solutions in the case of commuting hypotheses, and in the case where the two hypotheses can be orthogonal (in the latter case, we prove that the restriction to separable measurements generically prevents perfect distinguishability). In regards to quantum state verification, our work shows the existence of more efficient strategies for noisy measurement scenarios.

description: Despite the focus by stakeholders, the States and the Murray-Darling Basin Authority on exploring the economic costs and benefits of the proposed Murray-Darling Basin Plan, there are a number of issues relevant to an economic evaluation of the Plan that are easily overlooked. While a proposed Murray-Darling Basin plan has been released, water sharing agreements will continue to evolve and much detail remains to be worked out as part of implementation at the state level. Given this, we seek to synthesise current research on the costs and benefits of the Murray-Darling Basin plan. In doing so we discuss eight issues relevant to understanding the net-benefits of water reforms that, though recognised in the literature and policy debates, have become somewhat peripheral despite their potential importance. The first two issues are related to the potential social costs associated with reduced viability of communities and ongoing viability issues for farms. The next three issues are focused on benefits from the proposed Plan. This includes the estimation of benefits for downstream beneficiaries, the opportunity provided to farmers from selling water and the benefits associated with reductions in system risk due to non-incremental changes in ecosystems. The remaining three issues relate to approaches for maximising the benefits associated with the water reform process. This includes the evaluation of a wider range of options, consideration of how to better use water markets to assist farmers to manage risk, and evaluating not only how much water is needed but how it can be more effectively managed.

description: Australia’s very good animal health status faces a wide range of biosecurity challenges that will arise during the next decade from changes in disease risk, ecosystems, technology and the policy environment in which animal producers operate. An understanding of these challenges should help enable producers to adopt management strategies to make their enterprises more resilient, as well as help policy-makers make better-informed choices to maintain and improve the health of Australia’s animals and animal industries.
