description: In this paper we study the dynamics of smallholder participation in export value chains focusing on the example of small-scale broccoli producers in the highlands of Ecuador. A double hurdle model and a multi-spell cox duration model are used to explain the extent of participation and the hazards of dropping out of the export chain. The empirical results suggest that small farmers´ withdrawal from the export sector is in fact accelerated by hold-ups experienced in the past and that family ties play an important role in farmers’ marketing decisions. Negative external shocks – such as the bankruptcy of the main buyer in our case study – represent a major threat towards the sustainability of smallholder farmer inclusion in high-value chains, because farmer organizations often possess low resilience towards such events.

description: We determine all distant-isomorphisms between projective lines over semilocal rings. In particular, for those semisimple rings that do not have a simple component which is isomorphic to a field, every distant isomorphism arises from a Jordan isomorphism of rings and a projectivity. We show this by virtue of a one-one correspondence linking the projective line over a semisimple ring with a Segre product of Grassmann spaces.

description: The outcomes of agricultural investment decisions are affected by the risk in price, cost, and yield outcomes. To examine those risks, net present value models with Monte Carlo simulation are used to analyze the viability of greenhouse tomato investment decisions. The analysis is further extended by utilizing a real options approach. The results indicate that a grower would choose to continue field-grown tomato production due to high option values and risk aversion. Moreover, some policies or market conditions which increase credit availability, decrease energy prices, reduce tomato price fluctuation and/or facilitate effective risk management strategies would make the greenhouse production preferable.

description: The electronic spectral function of BaNi$_2$As$_2$ is investigated using both the angle-resolved photoemission spectroscopy (ARPES) and a combined computational scheme of local density approximation together with dynamical mean-field theory (LDA+DMFT). In contrast to well studied isostructural iron arsenide high temperature superconductors, the BaNi$_2$As$_2$ demonstrate weak correlation effects although Ni-3d elections have even lager on-site interaction than Fe-3d ones. LDA+DMFT effective mass enhancement for bands crossing the Fermi level is found to be only about $1.2$ which agrees well with ARPES data. This reduction of the correlation manifestation with respect to iron pnictides comes from the increase of 3d-orbital filling, when going from Fe to Ni. The electron correlations cause remarkable reconstruction of the bare BaNi$_2$As$_2$ LDA band structure below $-0.8$ eV due to self-energy effect. A simplified toy model to understand weakness of correlation effects in BaNi$_2$As$_2$ and to describe the LDA+DMFT self-energy shape is discussed. For more realistic comparison of LDA+DMFT spectral function maps with ARPES data we take into account several experimental features: the photoemission cross-section, the experimental energy and angular resolutions and the photo-hole lifetime effects. Thus presented here LDA+DMFT calculations with experimental features included provide nearly qualitative agreement with ARPES data and assure the observation of a dramatic apparent decrease of the correlation strength compared to the Fe compounds.

description: This paper examines the impact of timber trade liberalisation on economic welfare and forest conservation in Sri Lanka. A partial equilibrium market simulation model was used to analyse the welfare impacts. Results show that removal of all border charges reduce timber price by about 25%. Decline in timber price reduces the incentives for illegal logging and enhances forest conservation in Sri Lanka. The price reduction also results in an increase of consumer surplus by about US $ 40 million per year. Timber trade liberalisation reduces local supply by about 12% to 31% depending on the elasticity of supply. The reduction of local supply can prevent 6,985, 13,971 and 17,469 ha of deforestation under the inelastic, unitary elastic and elastic demand and supply assumptions, respectively.

description: The Chandra X-ray Observatory (CXO), NASA's latest ``Great Observatory'', was launched on July 23, 1999 and reached its final orbit on August 7, 1999. The CXO is in a highly elliptical orbit, approximately 140,000 km x 10,000 km, and has a period of approximately 63.5 hours (~2.65 days). Communication with the CXO nominally consists of 1-hour contacts spaced 8-hours apart. Thus, once a communication link has been established, it is very important that the health and safety status of the scientific instruments as well as the Observatory itself be determined as quickly as possible. In this paper, we focus exclusively on the automated health and safety monitoring scripts developed for the Advanced CCD Imaging Spectrometer (ACIS) to use during those 1-hour contacts. ACIS is one of the two focal plane instruments on-board the CXO. We present an overview of the real-time ACIS Engineering Data Web Page and the alert schemes developed for monitoring the instrument status during each communication contact. A suite of HTML and PERL scripts monitors the instrument hardware house-keeping electronics (i.e., voltages and currents) and temperatures during each contact. If a particular instrument component is performing either above or below pre-established operating parameters, a sequence of email and alert pages are spawned to the Science Operations Team of the Chandra X-ray Observatory Center so that the anomaly can be quickly investigated and corrective actions taken if necessary. We also briefly discuss the tools used to monitor the real-time science telemetry reported by the ACIS flight software. The authors acknowledge support for this research from NASA contract NAS8-39073.

description: The Spike-heeled Lark Chersomanes albofasciata is a peculiar, short-tailed lark confined to southern, central and East Africa. Typical of resident larks, it exhibits marked geographic variation in plumage colour, which has historically resulted in large numbers of subspecies being described. This variation was examined by sequencing 630 base pairs of the cytochrome b gene in 39 individuals and morphometric measurements of 320 birds. Nine of the 14 southern African C. albofasciata subspecies defined by Clancey in 1980 were sampled for assessing genetic variation, as well as one population from northern Namibia (C. a. boweni) and the isolated C. [a.] beesleyi population in Tanzania. Within South Africa, 16 maternal lineages were identified. The haplotype network revealed three geographically distinct haplogroups: Namaqualand, Karoo and Eastern grasslands, which did not follow past or existing subspecies ranges. Our data thus suggest incongruence between genetic variation and phenotype in South Africa. The boundaries and relationship among the phylogeographic haplogroups and morphometric measurement were similar to the closely related Long-billed Lark Certhilauda curvirostris complex suggesting similar processes during their evolutionary history. The existing subspecies designations are clearly not supported by the genetic data presented here and thus more research into this complex is required. Further research should include sampling of Spike-heeled Larks in underrepresented areas of the species’ range and the use of additional genetic markers to improve our understanding of the evolutionary history of this complex. C. [a.] beesleyi was sister to all haplotypes sampled and smaller in size than all subspecies measured. Although the status of the contentious C. [a.] beesleyi has still not been resolved, we have added morphometric data supporting its isolation from other subspecies. Its limited and isolated range warrants increased conservation efforts and we propose its recognition as an evolutionarily significant unit.

description: A wide variety of activation functions have been proposed for neural networks. The Rectified Linear Unit (ReLU) is especially popular today. There are many practical reasons that motivate the use of the ReLU. This paper provides new theoretical characterizations that support the use of the ReLU, its variants such as the leaky ReLU, as well as other activation functions in the case of univariate, single-hidden layer feedforward neural networks. Our results also explain the importance of commonly used strategies in the design and training of neural networks such as "weight decay" and "path-norm" regularization, and provide a new justification for the use of "skip connections" in network architectures. These new insights are obtained through the lens of spline theory. In particular, we show how neural network training problems are related to infinite-dimensional optimizations posed over Banach spaces of functions whose solutions are well-known to be fractional and polynomial splines, where the particular Banach space (which controls the order of the spline) depends on the choice of activation function.

In this method, we do not solve any transfer matrix-like equations. A comparison between the $β$-expansions of the specific heat and the magnetic susceptibility for the $s=1/2$ and $s=1$ one-dimensional Ising models is presented. We show that those expansions have poorer convergence when the auxiliary function of the model has singularities.

description: Import shares of liquid milk, powdered milk, condensed milk and other milk products were estimated to determine their relative competitiveness. The change of import shares with changes of exchange rate and world price of milk. The analysis based on yearly data between 1975-2006 showed that relative CIF prices and incomes were important factors influencing the market shares of milk and milk products. The results also showed that imported milk powder is price inelastic and a weak substitute for other imported milk products. The milk powder import shares will decline marginally with depreciation of exchange rate by 5% and increase of world price of milk over a forecasted period of 5-7 years. However, these changes are not significant.

The interaction among the different microcrystallites is mediated by a single-mode cavity field. It is found that the symmetric sharing of the entanglement (measured by the concurrence) between any pair of the excitonic state with $N$ qubits defined by the number states (vacuum and a single-exciton states) or the coherent states (odd and even coherent states) can be prepared by the cavity field for this system.

description: In typical statistical mechanical systems the grand canonical partition function at finite volume is proportional to a polynomial of the fugacity $e^{μ/T}$. The zero of this Lee-Yang polynomial closest to the origin determines the radius of convergence of the Taylor expansion of the pressure around $μ=0$. The computationally cheapest formulation of lattice QCD, rooted staggered fermions, with the usual definition of the rooted determinant, does not admit such a Lee-Yang polynomial. We argue that the radius of convergence is then bounded by the spectral gap of the reduced matrix of the unrooted staggered operator. This is a cutoff effect that potentially affects all estimates of the radius of convergence with the standard staggered rooting. We suggest a new definition of the rooted staggered determinant at finite chemical potential that allows for a definition of a Lee-Yang polynomial, and, therefore of the numerical study of Lee-Yang zeros. We also describe an algorithm to determine the Lee-Yang zeros and apply it to configurations generated with the 2-stout improved staggered action at $N_t = 4$. We perform a finite-volume scaling study of the leading Lee-Yang zeros and estimate the radius of convergence of the Taylor expansion extrapolated to an infinite volume. We show that the limiting singularity is not on the real line, thus giving a lower bound on the location of any possible phase transitions at this lattice spacing. In the vicinity of the crossover temperature at zero chemical potential, the radius of convergence turns out to be $μ_B/T \approx 2$ and roughly temperature independent. Our simulations are performed at strange quark chemical potential $μ_s=0$, but the method can be straightforwardly extended to strangeness chemical potential $μ_S=0$ or strangeness neutrality.

Our proposal is viable with realistic system parameters, simple "keyboard" gating, and projective measurement. Simulation results indicate entanglement can be demonstrated with moderately accurate gate operations. In addition to providing further evidence for the existence of the Majorana bound states, our proposal could be used as an experimental stepping stone to more complicated braiding experiments.

description: We investigate the phonon mechanism for the orientational pinning of Wigner crystals and stripes in two-dimensional electron layers in GaAs matrices. We find the orientation of bilayer Wigner crystals on the (001), (111), (0-11) and (311) interfaces versus the interlayer distance and determine the regions of parameters, where polydomain structures can emerge. For the stripe states in electron layers situated close to the (001) surface we show that the interference between the piezoelectric and deformation potential interaction may be responsible for the preferable orientation of the stripes along the [110] direction. For the bilayer system on the (001) interfaces we predict the suppression of the resistance anisotropy.

description: Commercialization of agricultural sector through diversification into high value agriculture has been identified as a viable strategy for up-scaling the socio-economic status of poor rural farmers, the success of which is largely dependant upon their degree of market orientation. This study attempted to investigate business orientation of poor farmers in terms of the extent to which they are market as opposed to production oriented, which was also dependant upon their degree of commercial orientation. The study was conducted among 897 poor dry zone farmers. The study first investigated into the commercial versus subsistence orientation of the farmers. The routine decision criteria adopted by farmers that were devoid of market considerations were considered as production orientated whereas the corresponding decisions that deviated from routine production orientation towards greater integration of market considerations were considered as market orientated. A score were assigned from a scale varying from 1 to 6 for both orientations representing the number of production/marketing criteria considered by each farmer in production related decision making. Findings revealed that the overall business orientation of the farmers culminated in production orientation with a little deviation towards market orientation in the case of Other Field Crops (OFCs), which was mainly grown for commercial purposes as opposed to paddy and vegetables that were mainly grown for fulfilling subsistence requirements. This brings about the need for placing a greater emphasis on inculcating market oriented mind sets among farmers for making rural socio-economic development a reality.

description: In this paper a generalisation of the notion of polarity is exhibited which allows to completely describe, in an incidence-geometric way, the linear complexes of $h$-subspaces. A generalised polarity is defined to be a partial map which maps $(h-1)$-subspaces to hyperplanes, satisfying suitable linearity and reciprocity properties. Generalised polarities with the null property give rise to a linear complexes and vice versa. Given that there exists for $h>1$ a linear complex of $h$-subspaces which contains no star --this seems to be an open problem over an arbitrary ground field --the combinatorial structure of a partition of the line set of the projective space into non-geometric spreads of its hyperplanes can be obtained. This line partition has an additional linearity property which turns out to be characteristic.

description: To transcribe spoken language to written medium, most alphabets enable an unambiguous sound-to-letter rule. However, some writing systems have distanced themselves from this simple concept and little work exists in Natural Language Processing (NLP) on measuring such distance. In this study, we use an Artificial Neural Network (ANN) model to evaluate the transparency between written words and their pronunciation, hence its name Orthographic Transparency Estimation with an ANN (OTEANN). Based on datasets derived from Wikimedia dictionaries, we trained and tested this model to score the percentage of correct predictions in phoneme-to-grapheme and grapheme-to-phoneme translation tasks. The scores obtained on 17 orthographies were in line with the estimations of other studies. Interestingly, the model also provided insight into typical mistakes made by learners who only consider the phonemic rule in reading and writing.

We find that the bond strength of the nanowire is about twice that of a bulk metallic bond. We perform ab initio calculations of the force at chain fracture and compare quantitatively with experimental measurements. The observed mechanical failure and nanoelastic processes involved during atomic wire fabrication are investigated using molecular dynamics (MD) simulations, and we find that the total effective stiffness of the nanostructure is strongly affected by the detailed local atomic arrangement at the chain bases.

description: Software-defined networks (SDNs) are a huge evolution in simplifying implementation and network operation which have reduced costs and made the network programmable. Although SDNs are a suitable option for solving some of the previous problems, but they have some challenges as any other new technology. Resource allocation and balance control in network is one of the main challenges of this technology which is studied in this paper. In this study, a new approach is proposed for improving memory resource allocation in network using load distribution clusters. Since in the proposed method, K-mean++ algorithm is used for clustering, load balancing of clusters can be used to preserve load balance of the network. In the proposed method, data with higher recall is transmitted to high-quality clusters in terms of average number of hubs and lower average delay between server and user. In the proposed method, by increasing number of clusters, higher memory is created in the network.

description: This paper examines the impact of price originated in the Central Rice Market (i.e. Colombo) on the price formation in a set of geographically dispersed Regional Rice Market in Sri Lanka (i.e. Anuradhapura, Kandy, Kurunegala, Nuwara-Eliya and Pollonnaruwa). It uses the monthly retail prices of rice in these markets from January 1996 to December 2003. The outcome of the analysis suggests that prices in these markets, irrespective of the whether they are surplus or deficit markets, were highly integrated both in the short-run and long-run perspectives. It has important implications for food and agricultural policy, i.e. government interventions at the Central Market such as food imports and export bans etc. are effective in Regional Markets.

description: Market impacts of technological change in Canadian agriculture are measured within a CGE framework using 2001 input-output data with agriculture disaggregated to six sectors and thirteen commodities. Technological change is modelled as productivity rises in the use of intermediate inputs and of primary factors. Impacts on output, intermediate use of output, foreign trade, final consumption, returns to primary factors and relative price are calculated for primary and processed food products. Impacts of technological change can be summarised into two general outcomes. First, supply managed sectors respond to technological change differently than other agricultural sectors. In the former, economic rents generated from quotas increase while in the latter, outputs, exports, and final consumption increase along with declines of relative supply prices. Second, large relative price declines for other commodities lead to consumer gains.

description: Currently, the small-scale farmers in Sri Lanka are loosing competitiveness and rapidly moving out of agriculture, lack of access as well as well defined rights to land being major limitations. Possibility of increasing agriculture production through improved land rental markets in the alienated state lands was conversed in this study and results revealed that the removal of restrictions is likely to facilitate smooth functioning of rental market and thereby improve the land use efficiency. The study concluded that provided a conducive economic environment, land rental market can be used as an effective tool in the rural development process of the country.

description: This lecture note reviews a variety of transport and thermodynamic measurements of electron decoherence time in low-dimensional conductors at low temperature. The mechanism of dephasing by electron interaction mediated by an arbitrarily small number of magnetic impurities is neither applicable to our linear-response measurements of weak localization, nor is it observed in the recent high-field measurements of the decoherence time in nominally pure quasi-one dimensional gold wires. The source of decoherence, after extensive experiments, still appears to be intrinsic.

description: We show that the Virasoro conjecture in Gromov--Witten theory holds for the the total space of a toric bundle $E \to B$ if and only if it holds for the base $B$. The main steps are: (i) we establish a localization formula that expresses Gromov--Witten invariants of $E$, equivariant with respect to the fiberwise torus action, in terms of genus-zero invariants of the toric fiber and all-genus invariants of $B$; and (ii) we pass to the non-equivariant limit in this formula, using Brown's mirror theorem for toric bundles.

description: Consider a smooth complex surface $X$ which is a double cover of the projective plane $\mathbb{P}^2$ branched along a smooth curve of degree $2s$. In this article, we study the geometric conditions which are equivalent to the existence of Ulrich line bundles on $X$ with respect to this double covering. Also, for every $s\geq 1$, we describe the classes of such surfaces which admit Ulrich line bundles and give examples.

How Markets Alleviate the Excessive Choice Effect: A Field Experiment on Craft Beer Choice

description: Research in psychology suggests that, somewhat paradoxically, providing consumers more choice can reduce the likelihood of making a purchase, producing the so-called excessive choice effect (ECE). To the extent the ECE exists, firms have an incentive to alleviate the effect through a variety of consumer-focused institutions that lower search costs. This study determines the effectiveness of three consumer-focused institutions on the excessive choice effect in a field experiment focused on beer sales in a restaurant. We manipulate the number of options on the menu (6 vs. 12) in addition to the use of search cost lowering consumer-focused institutions (a control, a menu, a menu with a special prominently displayed, a menu with local options prominently highlighted, and a menu with beer advocate scores). Although we find that consumers tend to be more likely to order beer when presented 6 rather than 12 options, the differences are often not significant depending which data are used and how it is analyzed. Highlighting specials or listing beer rankings have an effect on consumer choices, and have the potential to decrease the excessive choice effect. The experiment also suggests including a special is the most effective way to increase sales of a product category, but not the specific product itself.
Generation and interaction of solitons in Bose-Einstein condensates

description: Generation, interaction and detection of dark solitons in Bose-Einstein condensates is considered. In particular, we focus on the dynamics resulting from phase imprinting and density engineering. The generation of soliton pairs as well as their interaction is also considered. Finally, motivated by the recent experimental results of Cornish et al. (Phys. Rev Lett. 85, 1795, 2000), we analyze the stability of dark solitons under changes of the scattering length and thereby demonstrate a new way to detect them. Our theoretical and numerical results compare well with the existing experimental ones and provide guidance for future experiments.

Global, Non-Scattering Solutions to the Energy Critical Yang-Mills Problem
Creators: name: Pillai, Mohandas
Publisher: name: arXiv
Year: 2019
Subjects: subject: Analysis of PDEs (math.AP)
subject: FOS: Mathematics

description: We consider the Yang-Mills problem on $\mathbb{R}^{1+4}$ with gauge group $SO(4)$. In an appropriate equivariant reduction, this Yang-Mills problem reduces to a single scalar semilinear wave equation. This semilinear equation admits a one-parameter family of solitons, each of which is a re-scaling of a fixed solution. In this work, we construct a class of solutions, each of which consists of a soliton whose length scale is asymptotically constant, coupled to large radiation, plus corrections which slowly decay to zero in the energy norm. Our class of solutions includes ones for which the radiation component is only "logarithmically" better than energy class. As such, the solutions are not constructed by apriori assuming the length scale to be constant. Instead, we use an approach similar to a previous work of the author regarding wave maps. In the setup of this work, the soliton length scale asymptoting to a constant is a necessary condition for the radiation profile to have finite energy. An interesting point of our construction is that, for each radiation profile, there exist one-parameter families of solutions consisting of the radiation profile coupled to a soliton, which has any asymptotic value of the length scale.

Eisenstein series and automorphic representations

description: We provide an introduction to the theory of Eisenstein series and automorphic forms on real simple Lie groups G, emphasising the role of representation theory. It is useful to take a slightly wider view and define all objects over the (rational) adeles A, thereby also paving the way for connections to number theory, representation theory and the Langlands program. Most of the results we present are already scattered throughout the mathematics literature but our exposition collects them together and is driven by examples. Many interesting aspects of these functions are hidden in their Fourier coefficients with respect to unipotent subgroups and a large part of our focus is to explain and derive general theorems on these Fourier expansions. Specifically, we give complete proofs of the Langlands constant term formula for Eisenstein series on adelic groups G(A) as well as the Casselman--Shalika formula for the p-adic spherical Whittaker function associated to unramified automorphic representations of G(Q_p). In addition, we explain how the classical theory of Hecke operators fits into the modern theory of automorphic representations of adelic groups, thereby providing a connection with some key elements in the Langlands program, such as the Langlands dual group LG and automorphic L-functions. Somewhat surprisingly, all these results have natural interpretations as encoding physical effects in string theory. We therefore also introduce some basic concepts of string theory, aimed toward mathematicians, emphasising the role of automorphic forms. In particular, we provide a detailed treatment of supersymmetry constraints on string amplitudes which enforce differential equations of the same type that are satisfied by automorphic forms. Our treatise concludes with a detailed list of interesting open questions and pointers to additional topics which go beyond the scope of this book.
