description: The Food & Agriculture Risk Management for the 21st Century Act (FARM 21) formally introduced June 13th by U.S. Representatives Ron Kind (D-WI), Jeff Flake (R-AZ), Joe Crowley (D-NY), and David Reichert (R-WA), would significantly change most of U.S. agricultural policy. The proposed changes are wide ranging from commodity programs to energy, conservation, and food and nutrition programs. Given the breadth of the changes, it is important to have some indication of the impacts on producers if this proposal were to be adopted. While FARM 21 has a broad set of priorities that support would be directed to, this report focuses on the proposed changes to the producer safety net programs contained in Title I -- direct payments (DPs), counter-cyclical payments (CCPs), and loan deficiency payments (LDPs)/marketing loan gains (MLGs). These programs would be transitioned to farmer held “risk management accounts” (RMAs).

description: There are several ways to define program equivalence for functional programs with algebraic effects. We consider two complementing ways to specify behavioural equivalence. One way is to specify a set of axiomatic equations, and allow proof methods to show that two programs are equivalent. Another way is to specify an Eilenberg-Moore algebra, which generate tests that could distinguish programs. These two methods are said to complement each other if any two programs can be shown to be equivalent if and only if there is no test to distinguish them. In this paper, we study a generic method to formulate from a set of axiomatic equations an Eilenberg-Moore algebra which complements it. We will look at an additional condition which must be satisfied for this to work. We then apply this method to a handful of examples of effects, including probability and global store, and show they coincide with the usual algebras from the literature. We will moreover study whether or not it is possible to specify a set of unary Boolean modalities which could function as distinction-tests complementing the equational theory.

description: We discuss the phase dependent nonlocal thermoelectric effect in a topological Josephson junction in contact with a normal-metal probe. We show that, due to the helical nature of topological edge states, nonlocal thermoelectricity is generated by a purely Andreev interferometric mechanism. This response can be tuned by imposing a Josephson phase difference, through the application of a dissipationless current between the two superconductors, even without the need of applying an external magnetic field. We discuss in detail the origin of this effect and we provide also a realistic estimation of the nonlocal Seebeck coefficient that results of the order of few $μV/K$.

description: We introduce a stochastic fractional calculus. As an application, we present a stochastic fractional calculus of variations, which generalizes the fractional calculus of variations to stochastic processes. A stochastic fractional Euler-Lagrange equation is obtained, extending those available in the literature for the classical, fractional, and stochastic calculus of variations. To illustrate our main theoretical result, we discuss two examples: one derived from quantum mechanics, the second validated by an adequate numerical simulation.

description: The global pandemic due to the novel Severe Acute Respiratory Syndrome Corona Virus 2 (SARS-CoV-2) has taken more than a million lives. Lack of definitive vaccine/drugs against this highly contagious virus has accelerated exploratory research on novel natural and synthetic inhibitors. Tea is a rich source of bioactives and known to have antiviral properties. In this study, an in silico strategy involving ADMET property screening, receptor–ligand docking and molecular dynamic (MD) simulation was employed to screen potential tea bio-active inhibitors against three selected targets (RdRp, 3CLpro and PLpro) of SARS-CoV-2. Among the 70 tea bioactives screened, theaflavin 3,3’-di-gallate (TF3), Procyanidin B2 and Theaflavin 3-gallate (TF2a) exhibited highest binding affinities towards RdRp, 3CLpro/Mpro and PLpro targets of SARS-CoV-2 with low docking scores of −14.92, −11.68 and −10.90 kcal/mol, respectively. All of them showed a substantial number of hydrogen bonds along with other interactions in and around the active sites. Interestingly, the top bioactives in our study showed higher binding affinities compared with known antiviral drugs. Further, the top protein–ligand complexes showed less conformational changes during binding when subjected to MD simulation for 100 nanoseconds. The MMPBSA results revealed that RdRp-TF3, 3CLpro-Procyanidin B2 and PLpro-TF2a complexes were stable with binding free energies of −93.59 ± 43.97, −139.78 ± 16.51 and −96.88 ± 25.39 kJ/mol, respectively. Our results suggest that theaflavin 3,3’-digallate, Theaflavin 3-gallate and Procyanidin B2 found in black tea have the potential to act as inhibitors for selected targets of SARS-CoV-2 and can be considered as drug candidates in future studies against COVID-19.

description: Preferential pricing was one of several concerns leading to mandatory price reporting. Seven years of “new” data from mandatory reports are examined to determine if evidence exists of preferential pricing by packers for fed cattle and slaughter hogs. Weekly data show some alternative marketing methods track closer to cash market prices than others. Some differences can be explained, while others are not as clear. Evidence was found that cash prices lead prices for alternative marketing methods on rising markets but trail them on declining markets.

description: This study explores workplace stress, its causes, effects, and the effectiveness of stress management programs. Based on a survey of 120 employees, major stressors identified include heavy workload, tight deadlines, and lack of support. Statistical analysis shows a relationship between stress management programs and reduced stress levels. However, no significant link was found between stress impact and employees' ability to concentrate. The study highlights the need for better support systems, improved managerial practices, and initiatives promoting work-life balance to manage stress effectively.

description: The performance of over 500 North Dakota farms, 2006-2007, is summarized using 16 financial measures. Farms are categorized by geographic region, farm type, farm size, gross cash sales, farm tenure, net farm income, debt-to-asset, and age of farmer to analyze relationships between financial performance and farm characteristics. Five-year averages, 2002-2006, and farm financial trends for the 1998-2007 period are also presented. In 2007, median and average acreage per farm was 2,000 and 2,478, respectively. Median and average cash farm revenue was $353,252 and $458,843, respectively. Over 70% of farms were crop farms and nearly one-third of farms had gross sales exceeding $500,000. Median age of farm operators was 47. Every financial measure for 2007 was much superior to in any other year for the 1998-2007 period. The highest median net farm income was $127,791 in 2007, followed by $49,181 in 2003. The lowest was $19,491 in 1998. The Red River Valley and crop farms typically had stronger profitability, solvency, and repayment capacity from 1998 to 2007 than other regions and farm types, respectively. Exceptions were 2007 when the central regions had the best regional performance and 2005 when the south central region and livestock farms had better performance. The 2007 and 2006 median net farm income for crop farms was $171,838 and $53,642, respectively, compared to only $25,531and $6,150 for livestock farms. Farms with sales less than $100,000 were over twice as likely to have debt-to-asset higher than 70 percent than were farms with sales greater than $500,000. Farms that own some crop land, but less than 40 percent were more likely to be crop farms, farm more acreage, have larger sales, and be more profitable. As expected, solvency and percent of crop land owned increased with farmer age. In 1999, 2000, 2003, 2004 and 2007 the rate of return on equity exceeded the rate of return on assets, which indicates that debt capital was employed profitably. Interest expense as a percent of gross revenue declined in 2007 because of a sharp increase in gross revenue, after increasing in 2005 and 2006 because of higher debt and interest rates.

description: I make performances using space, time, the body — and sometimes things — as materials. These performances attempt, through a personal and embodied investigation of these materials, to explore an intimacy with the viewer that engages with questions of individual and collective identity. My current work includes performative acts or gestures that evolve through a phenomenological process of inquiry. The work aims to challenge the ways we relate to each other physically, emotionally and conceptually inside the spaces we occupy in order to create moments of tangible engagement with each other. Through my art work, I am interested in finding a means to open up family histories, everyday experience and cultural and socio-political perspectives between the viewer and the artwork, in order to explore how this exchange can shift our interaction with the world, offering new ways of seeing and identification. As a form of research, the artwork investigates how the act of interpretation can draw the viewer into a performed reception, attempting to make essential the complex social relationships that exist in a shared space through activating what the viewer’s ‘part’ or ‘role’ is in relation to a work. To this end, my working processes include promoting an intimacy through reversing spatial relationships, using performance and the body to encourage an embodied response and drawing upon narrative conventions, such as metaphor, to further an interpretation that supports an intersubjective engagement in order to deepen the opportunity for the viewer to perform their own meaning in their reception of a work. Influenced by Merleau-Ponty’s theories of bodily perception, Claire Bishop’s writing on the physical relationship between art and viewer and Amelia Jones’ ideas on representation of the performed body and its role in meaning production, my research attempts to understand how we can create definite connections with the viewer through our shared attention to a work. As such, artists Tino Sehgal and Sophie Calle have been influences inside my practice.

description: For the first time in two decades, the Secretary of Agriculture provided the House and Senate Agriculture Committees a farm bill proposal from the Administration. The Administration’s Proposal is a comprehensive revision of the 2002 farm bill with suggested changes to all titles. Four major proposed changes to Title 1 Commodity Programs are analyzed and reported in this Briefing Paper. The four key policy changes analyzed are: - an increase in direct payment rates, - a reduction in loan rates for most crops, - the replacement of the counter cyclical payment (CCP) program with a counter cyclical revenue (CCR) program, and - a change in eligibility for farm program payments by using $200,000 adjusted gross income (AGI) for a means test. The economic impact of the Administration’s Proposal on the viability of 99 representative crop, dairy, and beef cattle farms is compared to a base situation of continuing the current farm bill through 2012. This report is a companion to FAPRI-UMC Report #11-07 that contains sector level impacts.
Combining predicate transformer semantics for effects: a case study in parsing regular languages

description: This paper describes how to verify a parser for regular expressions in a functional programming language using predicate transformer semantics for a variety of effects. Where our previous work in this area focused on the semantics for a single effect, parsing requires a combination of effects: non-determinism, general recursion and mutable state. Reasoning about such combinations of effects is notoriously difficult, yet our approach using predicate transformers enables the careful separation of program syntax, correctness proofs and termination proofs.

description: The Agricultural & Food Policy Center (AFPC) updated the comparison of corn and sorghum county loan rates following the general methodology outlined in the October 2002 Food and Agricultural Policy Research Institute (FAPRI) study on corn and sorghum loan rates. The study answers two questions: 1. Are the 2006 county loan rates established by USDA consistent with the Congressional mandate that national average loan rates for both commodities be $1.95 per bushel? 2. What would be the impact if USDA were to adopt a different weighting scheme in setting county loan rates while continuing to maintain the mandated national average loan rate? Specifically, what would be the impact on sorghum loan rates if each county’s loan rate were weighted by the county’s share of national production of sorghum and corn combined, rather than by each county’s share of national sorghum production alone?

description: We show that the conifold and deformed-conifold warped compactifications of the ten-dimensional type IIB supergravity, including the Klebanov-Strassler solution, are dynamically unstable in the moduli sector representing the scale of a Calabi-Yau space, although it can be practically stable for a quite long time in a region with a large warp factor. This instability is associated with complete supersymmetry breaking except for a special case and produces significant time-dependence in the structure of the four-dimensional base spacetime as well as of the internal space.

description: This report draws on a body of existing literature to assess the impact of trade preferences granted by the European Union on trade and welfare in developing countries. It is argued that the Everything But Arms amendment to the EU preference scheme will have limited effect on export potential and welfare in the least developed countries (LDCs). The EU would do well to simplify compliance with their rules of origin. When LDCs are granted deeper preferences under continued domestic agricultural policies in the EU, US, Canada and Japan, resources in LDCs will move towards the agricultural sector. The expected effect impact on LDCs of extending preferences to non-LDCs is quite small, while the negative effect of reductions of MFN tariffs under trade liberalisation is stronger.

Lack of definitive vaccine/drugs against this highly contagious virus has accelerated exploratory research on novel natural and synthetic inhibitors. Tea is a rich source of bioactives and known to have antiviral properties. In this study, an in silico strategy involving ADMET property screening, receptor–ligand docking and molecular dynamic (MD) simulation was employed to screen potential tea bio-active inhibitors against three selected targets (RdRp, 3CLpro and PLpro) of SARS-CoV-2. Among the 70 tea bioactives screened, theaflavin 3,3’-di-gallate (TF3), Procyanidin B2 and Theaflavin 3-gallate (TF2a) exhibited highest binding affinities towards RdRp, 3CLpro/Mpro and PLpro targets of SARS-CoV-2 with low docking scores of −14.92, −11.68 and −10.90 kcal/mol, respectively. All of them showed a substantial number of hydrogen bonds along with other interactions in and around the active sites. Interestingly, the top bioactives in our study showed higher binding affinities compared with known antiviral drugs. Further, the top protein–ligand complexes showed less conformational changes during binding when subjected to MD simulation for 100 nanoseconds. The MMPBSA results revealed that RdRp-TF3, 3CLpro-Procyanidin B2 and PLpro-TF2a complexes were stable with binding free energies of −93.59 ± 43.97, −139.78 ± 16.51 and −96.88 ± 25.39 kJ/mol, respectively. Our results suggest that theaflavin 3,3’-digallate, Theaflavin 3-gallate and Procyanidin B2 found in black tea have the potential to act as inhibitors for selected targets of SARS-CoV-2 and can be considered as drug candidates in future studies against COVID-19.

description: We present results of our study of two planetary nebulae (PNe), PB1 and PC 19. We use the optical spectra of these two PNe observed at 2 m Himalayan Chandra Telescope and also archival and literature data for the study. We use the morphokinematic code SHAPE to construct 3D morphologies of the PNe and the photoionization code CLOUDY to model the observed spectra. The 3D model of PB 1 consists of an elongated shell surrounded by a bipolar halo and that of PC 19 consists of an open lobed bipolar structure and a spiral filamentary pair. We analyze the ionization structure of the PNe by deriving several plasma parameters and by photoionization modelling. We estimate the elemental abundances of the the elements, He, C, N, O, Ne, S, Ar, and Cl, from our analysis. We find He, C and N abundances to be significantly higher in case of PB 1. We estimate different physical parameters of the central stars, namely effective temperature, luminosity and gravity, and of the nebula, namely hydrogen density profiles, radii, etc., from photoionization modelling. We estimate distances to the PNe as $\sim$4.3 kpc for PB 1 and as $\sim$5.6 kpc for PC 19 by fitting the photoionization models to absolute observed fluxes. Progenitor masses are estimated from theoretical evolutionary trajectories and are found to be $\sim$1.67 and $\sim$2.38 $M_{\odot}$ for PB 1 and PC 19, respectively.

description: We examine the quantum dynamics of cold atoms subjected to {\em pairs} of closely spaced $δ$-kicks from standing waves of light, and find behaviour quite unlike the well-studied quantum kicked rotor (QKR). Recent experiments [Jones et al, {\em Phys. Rev. Lett. {\bf 93}, 223002 (2004)}] identified a regime of chaotic, anomalous classical diffusion. We show that the corresponding quantum phase-space has a cellular structure, arising from a unitary matrix with oscillating band-width. The corresponding eigenstates are exponentially localized, but scale with a fractional power, $L \sim \hbar^{-0.75}$, in contrast to the QKR for which $L \sim \hbar^{-1}$. The effect of inter-cell (and intra-cell) transport is investigated by studying the spectral fluctuations with both periodic as well as `open' boundary conditions.

The aim of the report is to document this framework, in order to make a constructive contribution towards bridging the gap of understanding and accessibility of the countries' procedures in particular and of their trade relations in general. This report illustrates how the Chinese legal and institutional system differs from that in the EU. Laws, administrative documents and regulations are all part of the Chinese legal system and have an equally binding force. The Ministry of Agriculture (MoA) and the General Administration for Quality Supervision, Inspection and Quarantine (AQSIQ) are the two most important institutions monitoring food safety in China.

description: The $N$-particle free fermion state for quantum particles in the plane subject to a perpendicular magnetic field, and with doubly periodic boundary conditions, is written in a product form. The absolute value of this is used to formulate an exactly solvable one-component plasma model, and further motivates the formulation of an exactly solvable two-species Coulomb gas. The large $N$ expansion of the free energy of both these models exhibits the same O(1) term. On the basis of a relationship to the Gaussian free field, this term is predicted to be universal for conductive Coulomb systems in doubly periodic boundary conditions.

description: We explore a data structure that generalises rectangular multi-dimensional arrays. The shape of an n-dimensional array is typically given by a tuple of n natural numbers. Each element in that tuple defines the length of the corresponding axis. If we treat this tuple as an array, the shape of that array is described by the single natural number n. A natural number itself can be also treated as an array with the shape described by the natural number 1 (or the element of any singleton set). This observation gives rise to the hierarchy of array types where the shape of an array of level l+1 is a level-l array of natural numbers. Such a hierarchy occurs naturally when treating arrays as containers, which makes it possible to define both rank- and level-polymorphic operations. The former can be found in most array languages, whereas the latter gives rise to partial selections on a large set of hyperplanes, which is often useful in practice. In this paper we present an Agda formalisation of arrays with levels. We show that the proposed formalism supports standard rank-polymorphic array operations, while type system gives static guarantees that indexing is within bounds. We generalise the notion of ranked operator so that it becomes applicable on arrays of arbitrary levels and we show why this may be useful in practice.

description: This study provides a quantitative estimate of the potential economic consequences of multilateral trade reform under the WTO for Africa using a framework that explicitly incorporates issues of concern to the region, such as preference erosion, loss of tariff revenue, and trade facilitation. It also examines the impact of OECD agricultural support programmes on economic welfare and specialisation in Africa. In the static version of the GTAP model, the study finds that full liberalisation of trade would increase global welfare (income) by 0.3 per cent, but would add 0.7 per cent annually to income in the African region. Sub-Saharan Africa and, to a lesser extent, Southern Africa, are vulnerable to partial trade reforms as they incur losses from partial reform while all other regions derive positive gains from a liberalisation of minor scope.

description: New families of exact general relativistic thick disks are constructed using the ``displace, cut, fill and reflect'' method. A class of functions used to ``fill'' the disks is derived imposing conditions on the first and second derivatives to generate physically acceptable disks. The analysis of the function's curvature further restrict the ranges of the free parameters that allow phisically acceptable disks. Then this class of functions together with the Schwarzschild metric is employed to construct thick disks in isotropic, Weyl and Schwarzschild canonical coordinates. In these last coordinates an additional function must be added to one of the metric coefficients to generate exact disks. Disks in isotropic and Weyl coordinates satisfy all energy conditions, but those in Schwarzschild canonical coordinates do not satisfy the dominant energy condition.

description: This report provides an insight into the local business activity, livability and societal vitality in the rural areas of the Province of Friesland. The report encompasses a literature study and a regional analysis relating to these issues. The regional analysis was carried out in two municipalities in the Province of Friesland, namely Ferwerderadeel and Gaasterlân-Sleat. Eight interviews conducted in each municipality reviewed their strengths and weaknesses, as well as the opportunities and threats of relevance to their situation. The report also con-tains an account of the Naar een levendige economie in een vitaal platteland ('Towards a lively economy and a vital countryside') Workshop organised to discuss issues including the results from this study. Dit rapport geeft inzicht in de lokale bedrijvigheid, leefbaarheid en sociale vitaliteit in het landelijk gebied van Friesland. Het rapport bevat een literatuurstudie en een gebiedsgerich-te analyse rondom deze items. De gebiedsgerichte analyse heeft plaatsgevonden in twee Friese gemeenten: Ferwerderadeel en Gaasterlân-Sleat. Om knelpunten, sterke en zwakke punten evenals kansen en bedreigingen op te sporen, zijn per gemeente acht gesprekken gevoerd. In het rapport wordt ook verslag gedaan van de workshop 'Naar een levendige economie in een vitaal platteland' waarin onder meer de resultaten uit deze studie bespro-ken zijn.

description: Package managers are a very important part of Linux distributions but we have noticed two weaknesses in them: They use pre-built packages that are not optimised for specific hardware and often they are too heavy for a specific need, or packagesmay require plenty of time and resources to be compiled. In this paper, we present a novel Linux package manager which uses cloud computing features to compile and distribute Linux packages without impacting the end user's performance. We also show how Portage, Gentoo's package manager can be optimised for customisation and performance, along with the cloud computing features to compile Linux packages more efficiently. All of this resulting in a new cloud-based Linux package manager that is built for better computing performance.

description: In the calculus of dependent lambda eliminations (CDLE), it is possible to define inductive datatypes via lambda encodings that feature constant-time destructors and a course-of-values induction scheme. This paper begins to address the missing derivations for the dual, coinductive types. Our derivation utilizes new methods within CDLE, as there are seemingly fundamental difficulties in adapting previous known approaches for deriving inductive types. The lambda encodings we present implementing coinductive types feature constant-time constructors and a course-of-values corecursion scheme. Coinductive type families are also supported, enabling proofs for many standard coinductive properties such as stream bisimulation. All work is mechanically verified by the Cedille tool, an implementation of CDLE.

description: Recently, Witten proposed a topological string theory in twistor space that is dual to a weakly coupled gauge theory. In this lectures we will discuss aspects of the twistor string theory. Along the way we will learn new things about Yang-Mills scattering amplitudes. The string theory sheds light on Yang-Mills perturbation theory and leads to new methods for computing Yang-Mills scattering amplitudes.

description: In a graph $G$, a vertex dominates itself and its neighbours. A subset $S\subseteq V(G)$ is said to be a double dominating set of $G$ if $S$ dominates every vertex of $G$ at least twice. The minimum cardinality among all double dominating sets of $G$ is the double domination number. In this article, we obtain tight bounds and closed formulas for the double domination number of lexicographic product graphs $G\circ H$ in terms of invariants of the factor graphs $G$ and $H$.

description: Recent theoretical and empirical studies have focused on the structural properties of complex relational networks in social, biological and technological systems. Here we study the basic properties of twenty 1-square-mile samples of street patterns of different world cities. Samples are represented by spatial (planar) graphs, i.e. valued graphs defined by metric rather than topologic distance and where street intersections are turned into nodes and streets into edges. We study the distribution of nodes in the 2-dimensional plane. We then evaluate the local properties of the graphs by measuring the meshedness coefficient and counting short cycles (of three, four and five edges), and the global properties by measuring global efficiency and cost. As normalization graphs, we consider both minimal spanning trees (MST) and greedy triangulations (GT) induced by the same spatial distribution of nodes. The results indicate that most of the cities have evolved into networks as efficienct as GT, although their cost is closer to the one of a tree. An analysis based on relative efficiency and cost is able to characterize different classes of cities.

description: Scrupulous theoretical study of 8Be nucleus states, both clustered and non-clustered, is performed over a wide range of the excitation energies. The quantities which characterize the degree of the alpha-clustering of these states: spectroscopic factors, cluster form factors as well as the alpha-decay widths are computed in the framework of an accurate ab initio approach developed. Other basic properties of 8Be spectrum: the binding and excitation energies, mean values of the isospin are calculated simultaneously. In the majority of instances the results of the computations turn out to be in a good agreement with the spectroscopic data. A number of predictions are made and corresponding verification experiment is proposed. Prospects of the developed approach for nuclear spectroscopy are demonstrated.
