description: A four-body calculation of the $pnΛΛ$ bound state, $^{\ 4}_{ΛΛ}$H, is performed using the stochastic variational method and phenomenological potentials. The $NN$, $ΛN$, and $ΛΛ$ potentials are taken from a recent Letter by Filikhin and Gal, PRL{\bf 89}, 172502 (2002). Although their Faddeev-Yakubovsky calculation found no bound-state solution over a wide range of $ΛΛ$ interaction strengths, the present variational calculation gives a bound-state energy, which is clearly lower than the $_Λ^3{H}+Λ$ threshold, even for a weak $ΛΛ$ interaction strength deduced from a recent experimental $B_{ΛΛ}(^{6}_{ΛΛ}{He})$ value. The binding energies obtained are close to, and slightly larger than, the values obtained from the three-body $dΛΛ$ model in the Letter.

description: Research on the emergence of thermodynamics in closed quantum systems under unitary time evolution arrived at the consensus that generic systems equilibrate under rather general assumptions. A new focus of the field is thus on exceptions. Persistent oscillations are one possible hallmark of non-ergodic time evolution. While time-crystalline behavior results from, e.g., many-body localization, here we show that ever-revolving solitary waves emerge in flatband Heisenberg quantum spin systems. This phenomenon is rather general for a variety of frustrated spin systems in one, two, and three dimensions as well as for Hubbard systems.

description: Bipolar Disorder (BD) is a complex disease. It is heterogeneous, both at the phenotypic and genetic level, although the extent and impact of this heterogeneity is not fully understood. In this paper, we leverage recent advances in heterogeneity analysis to look for genetically-driven subgroups (i.e., biclusters) within the broad phenotype of Bipolar Disorder. We first apply this covariate-corrected biclustering algorithm to a cohort of 2524 BD cases and 4106 controls from the Bipolar Disease Research Network (BDRN) within the Psychiatric Genomics Consortium (PGC). We find evidence of genetic heterogeneity delineating a statistically significant bicluster comprising a subset of BD cases which exhibits a disease-specific pattern of differential-expression across a subset of SNPs. This disease-specific genetic pattern (i.e., 'genetic subgroup') replicates across the remaining data-sets collected by the PGC containing 5781/8289, 3581/7591, and 6825/9752 cases/controls, respectively. This genetic subgroup (discovered without using any BD subtype information) was more prevalent in Bipolar type-I than in Bipolar type-II. Our methodology has successfully identified a replicable homogeneous genetic subgroup of bipolar disorder. This subgroup may represent a collection of correlated genetic risk-factors for BDI. By investigating the subgroup's bicluster-informed polygenic-risk-scoring (PRS), we find that the disease-specific pattern highlighted by the bicluster can be leveraged to eliminate noise from our GWAS analyses and improve risk prediction. This improvement is particularly notable when using only a relatively small subset of the available SNPs, implying improved SNP replication. Though our primary focus is only the analysis of disease-related signal, we also identify replicable control-related heterogeneity.

description: It is known that unambiguous discrimination among non-orthogonal but linearly independent quantum states is possible with a certain probability of success. Here, we consider a variant of that problem. Instead of discriminating among all of the different states, we shall only discriminate between two subsets of them. In particular, for the case of three non-orthogonal states, we show that the optimal strategy to distinguish between a set containing one of the states from the set containing the other two has a higher success rate than if we wish to discriminate among all three states. Somewhat surprisingly, for unambiguous discrimination the subsets need not be linearly independent. A fully analytical solution is presented, and we also show how to construct generalized interferometers (multiports) that provide an optical implementation of the optimal strategy.

description: ASEAN is host to seven of the world’s 25 biodiversity hotspots. Failure of governments and their peoples to protect and conserve the region’s rich biodiversity is one of the greatest threats to the over 500 million people of ASEAN. As in other areas of the developing world, biodiversity conservation demands a delicate balance between development and conservation. The region’s rich biodiversity is inextricably linked to the livelihood of its people; about 65% of its population is dependent on its agricultural sector. The sector is a prime contributor to food security, employment, income generation and overall prosperity of the region. The linkage between biodiversity and agriculture is further emphasised as a result of global conventions and agreements that deal with the threats posed by invasive alien species to natural and agro-environments and issues of environmental sustainability. Biosecurity, together with biosafety, proposes a strategic and integrated approach that encompasses policy and regulatory frameworks for analysing and managing relevant risks to human, animal and plant life and health, and associated risks to the environment. The concept of managing these risks in a holistic manner has, however, not yet been fully embraced by developing countries, where biosecurity continues to be managed on a sector basis, often with separate policy and legislative frameworks. The migration towards a more harmonised and integrated approach, with the different sectors and components of biosecurity working towards common goals to take advantage of the available synergies and complementarities is often plagued by difficulties in cross-institutional cooperation and commitment, and agreement on sharing of limiting human capacity and resources.

description: A sustainable strategy to nourish the planet and its people must also promote biodiversity conservation. This strategy will have to include reduction in land degradation and unsustainable overuse of fertilisers, pesticides, fungicides, herbicides, and irrigation water. A case can be made for conserving biodiversity as a source of traits for incorporation, by different genetic tools, into food plants and animals, but an even stronger case can be made for a conserved biodiversity to supply ecosystem services that will nourish the planet and its occupants into the future. Biodiversity is under severe threat from many angles. One of the best ways to promote biodiversity is to preserve native habitats. By maintaining or even increasing yields on existing land, biotechnology crops can help to minimise expansion of agriculture into natural areas. It has also been estimated that agricultural biotechnology has changed pesticide spraying so as to greatly reduce greenhouse gas emissions and decrease environmental impacts of insecticides and herbicides. Gene flow from cultivated, including biotechnology-based, crops to and from wild plants is known to occur. The consequences of this flow vary from species to species, but as a general rule, do not pose a significant threat to biodiversity.

Holy Stranger Daily Ghost
Creators: name: White, Evan
Publisher: name: University of Massachusetts Amherst
Year: 2014

These poems do not cohere around any single drive, ethic, or experience, and they do not even express, I don’t think, a consistent mode of seeing or being seen. I do hope there is some aspiration, some active dreaming in here for the latter possibility—that the “lyric I” (though I think the “lyric Me” is more apt a word for the poetic voice’s automatic, reflexive self-scrutiny) might be regarded—and, through mysterious reactions, amplified or diminished, transformed or transfixed, by the objects it sets out to capture. Even if the inevitable and old (and always renewed, and always dignified, if growing always old) project of overcoming the ego had any chance of success, it isn’t what we’re about. We are content, and poets see an invitation, to receive the Holy Ghost of the poem’s counterturned gaze, its anti-attention. In the poems we are content to perpetually appear under all the eyes we set up in the ether, beyond our reach. And the more outsides we create, and the more often we turn ourselves into offerings for re-seeings, outside-in, the closer our brushes with a casual and occasional grace.

description: This article is another attempt of a comprehensive solution in the field of steganography data transmission. We also consider software model prototype that fully implements the process of hidden messages transmission in digital photographs. All stages of hidden message processing on the whole way from the sender to the recipient are taken into account. The programming model uses a discrete wavelet transform and new hiding algorithms based on the «Arnold cat map» decomposition. The efficiency of using noise-resistant coding methods and multithreshold decoding to ensure high probability of integrity and reliability of hidden messages when transmitting them through communication channels with a high level of noise is also shown.

description: While scalable error correction schemes and fault tolerant quantum computing seem not to be universally accessible in the near sight, the efforts of many researchers have been directed to the exploration of the contemporary available quantum hardware. Due to these limitations, the depth and dimension of the possible quantum circuits are restricted. This motivates the study of circuits with parameterized operations that can be classically optimized in hybrid methods as variational quantum algorithms (VQAs), enabling the reduction of circuit depth and size. The characteristics of these Parameterized Quantum Circuits (PQCs) are still not fully understood outside the scope of their principal application, motivating the study of their intrinsic properties. In this work, we analyse the generation of random states in PQCs under restrictions on the qubits connectivities, justified by different quantum computer architectures. We apply the expressibility quantifier and the average entanglement as diagnostics for the characteristics of the generated states and classify the circuits depending on the topology of the quantum computer where they can be implemented. As a function of the number of layers and qubits, circuits following a Ring topology will have the highest entanglement and expressibility values, followed by Linear/All-to-all almost together and the Star topology. In addition to the characterization of the differences between the entanglement and expressibility of these circuits, we also place a connection between how steep is the increase on the uniformity of the distribution of the generated states and the generation of entanglement. Circuits generating average and standard deviation for entanglement closer to values obtained with the truly uniformly random ensemble of unitaries present a steeper evolution when compared to others.

description: Using the pure spinor formalism for the superstring in an $AdS_5\times S^5$ background, a simple expression is found for half-BPS vertex operators. At large radius, these vertex operators reduce to the usual supergravity vertex operators in a flat background. And at small radius, there is a natural conjecture for generalizing these vertex operators to non-BPS states.

description: Africa is home to diverse and genetically unique ruminant livestock and wildlife species. The continent, however, faces huge food security challenges, partly due to low productivity of the livestock. As a centre of cattle domestication, Africa hosts genetically unique cattle, being products of generations of co-evolution with diverse people, each selecting for different attributes under different production systems and environments. Over millennia, this diversity of purpose has led to rich and unparalleled blends of indigenous and exotic cattle. Different parasites and pathogens, whose vigour has been buoyed by variable but generally favourable tropical conditions, have coevolved and served as critical drivers, making African cattle some of the world’s most scientifically interesting and valuable populations. This diversity is being lost at an alarmingly rate, and insitu conservation will not significantly save it. These cattle can potentially provide adequate food and income to their keepers. First their genetic and phenotypic diversity should be understood, and then carefully tailored to specific production systems to improve their productivity. To realistically conserve these cattle, for which no conservation plans currently exist, available modern bio- and information technologies are needed to assemble and analyse complex sets of information on them. As the climate and pathogens all change, by smartly conserving (ex-situ) those at risk the genetic attributes critical for the world’s future food security challenges would be saved. This paper discusses the diversity of the African cattle and the need for their system-wide characterisation in order to allow their keepers to cope with the changing system, and minimise the loss of these unique genotypes.

The results of the two methods of calculations are in good agreement.

The two circle about each other and eventually fall in love, but almost as quickly old patterns reassert themselves for both. These challenges must be acknowledged and a new way envisioned before the love Liv and August share can mature into something more durable.
Socio-economic variables and modern contraceptive use among married women aged 15-49 in selected hamlets of rural central Java

description: The aim of this study is to describe the relation between socioeconomic variables and modern contraceptive use among currently married women aged 15 to 49 in rural Central Java. Due to the nature of the data which have been used the present study makes no attempt to represent all rural Central Java. It is suggested that the results of this study apply only to the selected hamlets. Nonetheless it is likely that the result do reflect characteristics of women in similar circumstances in rural Central Java. In accord with other studies done in Indonesia, this study supports the hypothesis of a positive relationship between socio-economic variables and modern contraceptive use. However the evidence shows that differences between socio-economic classes were small and there was substantial use of modern contraceptives even among the poor and less-educated women. The propensity to use modern contraceptives was influenced by access to information and the range of services available, and the ability to bear the socio-economic costs of using any methods available. It is likely that the family planning program, with the support of community leaders and family planning groups, has made a significant effort to reach the poor and less-educated in rural areas.

description: The production of food from marine and freshwaters is undergoing a profound revolution—from hunting to farming or from fishing to aquaculture. Fishing and aquaculture exploit and alter the biodiversity on which they are based, each in different but convergent ways. Fishing harvests a much larger range of biodiversity at ecosystem, species and genetic levels than aquaculture. Nearly 400 aquatic species are cultured and more than 5000 species captured in fisheries. Aquaculture and fishing tend to reduce genetic, species and ecosystem diversity, but along different pathways. Fishing reduces genetic and species diversity through selectively removing target individuals with desired characteristics, such as large size, and alters ecosystems. Aquaculture is currently developing across a broad front, using many different species but in inefficient ways. A deliberate program of careful species selection using a broad range of criteria for farming and markets, including food security, should be encouraged, along with research to close the lifecycles of the selected species, improved farm breeds and conservation of germplasm. Aquatic biodiversity for food production receives little policy and management attention but international research provides major support to its sustainable use and conservation.

This manuscript is a collection of short fiction. The stories explore power structures within Asian and gay male communities, blurring the lines between folklore and memoir, intimacy and abuse, passivity and control. They attempt to complicate and subvert my own self-image by engaging friends and family members who have had formative impacts on my life. In reaching for people and places that no longer exist, these stories function as elegies as well as coming-of-age narratives.

description: We present results for prompt photon and inclusive $π^0$ production in p-p and A-A collisions at RHIC and LHC energies. We include the full next-to-leading order radiative corrections and nuclear effects, such as nuclear shadowing and parton energy loss. We find the next-to-leading order corrections to be large and $p_T$ dependent. We show how measurements of $π^0$ production at RHIC and LHC, at large $p_T$, can provide valuable information about the nature of parton energy loss. We calculate the ratio of prompt photons to neutral pions and show that at RHIC energies this ratio increases with $p_T$ approaching one at $p_T \sim 10$ GeV, due to the large suppression of $π^0$ production. We show that at the LHC, this ratio has steep $p_T$ dependence and approaches 10% effect at $p_T \sim 20$ GeV.

We show that in the CDW phase, the Fermi arcs reconnect into either closed Fermi loops or Frieze patterns traversing the reconstructed surface mini-Brillouin zone. For the closed reconnection topology, the application of an out-of-plane magnetic field leads to a cyclotron motion of the surface electrons. We determine the cyclotron frequency as a function of the electron energy and the magnitude of the CDW gap $Δ$ for various orientations of the Fermi arcs. For weak coupling, the period of cyclotron motion is dominated by the time of traversal of the arc reconnection regions and is inversely proportional to $Δ$.

In the days following her grandfather’s death, Caroline Donovan could not shake him. Images of him flooded her mind while she was grading papers or shielding her face against a whip of late autumn wind, walking from the university to the T station. His stubbled face from below when she was child, the one arm draped over the back of his kitchen chair, his frame hunched beside the nursing home window, fists involuntarily clenched until the fingernails dug into chafed, bleeding palms—these hid in memory, and then sprang-up.
The Book of New Fish
Creators: name: Angus, Callum
Publisher: name: University of Massachusetts Amherst
Year: 2017

Deep in the library stacks, two transgender men unearth a moldy copy of the United States and Mexican Boundary Survey of 1857. The survey, in its dispassionate cataloging of every plant and animal unfortunate enough to be caught in the crosshairs of Manifest Destiny, energizes the nameless narrator and his lover Emilio to pen an alternative field guide to the border. The Book of New Fish rewrites the history of the Rio Grande through the eyes of its fish who—like the two trans men—bear witness to the violent beauty of living in between countries, identities, and genders. Covering ground from the Spanish conquistadors to invasive species and unraveling their relationship in the process, the project demands increasingly steep sacrifices of the main characters as they try to figure out why we hurt those we love most in the search for identity and belonging.

description: Advances in underwater imaging enable collection of extensive seafloor image datasets necessary for monitoring important benthic ecosystems. The ability to collect seafloor imagery has outpaced our capacity to analyze it, hindering mobilization of this crucial environmental information. Machine learning approaches provide opportunities to increase the efficiency with which seafloor imagery is analyzed, yet large and consistent datasets to support development of such approaches are scarce. Here we present BenthicNet: a global compilation of seafloor imagery designed to support the training and evaluation of large-scale image recognition models. An initial set of over 11.4 million images was collected and curated to represent a diversity of seafloor environments using a representative subset of 1.3 million images. These are accompanied by 3.1 million annotations translated to the CATAMI scheme, which span 190,000 of the images. A large deep learning model was trained on this compilation and preliminary results suggest it has utility for automating large and small-scale image analysis tasks. The compilation and model are made openly available for reuse at https://doi.org/10.20383/103.0614.

description: Groundnut is an important component of the national food supply. It does not only have nutritional and dietary value, groundnut also provides cash to farmers; enrich the soil with nitrogen through biological nitrogen fixation; and its haulms can be used as fodder and fuel. Groundnut production has not kept up with the demands both local and export markets especially in terms of volumes over time. This has been in part due to low average yields resulting from continuous use of unimproved seed. In turn Malawi’s groundnut exports have also generally dwindled over time. The analysis of Malawian groundnut production using the Policy Analysis Matrix methodology shows that both traditional and improved technology groundnut production are both privately and socially profitable. This leads to the conclusion that protectionist policies that would raise domestic groundnut prices above the import parity prices determined in world markets are unnecessary. However, investments in improved technology show profits that are greater than traditional technology. These are likely to be areas in which government investments would yield a significant rate of return and reduce dependence on world markets. In addition to investments in improved seed technology, government should also invest in improved technologies for post harvest handling.

description: In the given article the estimation of stationary characteristics of reliability of the generator equipment of telecommunication system (TCS) with use semi-Markov models is resulted. A generalized semi-Markov model of the process of functioning of generator equipment is proposed, with the separation of states reflecting the main operating modes of the TCS generator equipment. Based on the developed semi-Markov model, the stationary reliability characteristics of the generator equipment are calculated, which reflect its integral state.

description: Planetary magnetic fields are generated by the motion of conductive fluid in the planet's interior. Complex flows are not required for dynamo action; simple flows have been shown to act as efficient kinematic dynamos, whose physical characteristics are more straightforward to study. Recently, Chen et al. (2018, J. Fluid Mech. 839, 1–32) found the optimal, unconstrained kinematic dynamo in a sphere, which, despite being of theoretical importance, is of limited practical use. We extend their work by restricting the optimization to three simple two-mode axisymmetric flows based on the kinematic dynamos of Dudley & James (1989, Proc. R. Soc. A. 425, 407–429). Using a Lagrangian optimization, we find the smallest critical magnetic Reynolds number for each flow-type, measured using an enstrophy-based norm. A Galerkin method is used, in which the spectral coefficients of the fluid flow and magnetic field are updated in order to maximize the final magnetic energy. We consider the t01s01, t01s02 and t02s02 flows and find enstrophy-based critical magnetic Reynolds numbers of 107.7, 142.4 and 125.5 (13.7, 19.6 and 16.4, respectively, with the energy-based definition). These are up to four times smaller than the original flows. These simple and efficient flows may be used as benchmarks in future studies.

description: In this paper the sequential algorithm for generating a matrix of coefficients for a system of homogeneous differential equations describing a model of a nonstationary queueing system is proposed. Its comparison with the recursive algorithm is given. The optimal storage structure of the list of states for a sequential algorithm is given. A decrease of the performing time for the algorithm compared with the recursive one was noted due to no need to sort the list of states and matrix of coefficients.

description: The classical motion of spinning particles can be described without employing Grassmann variables or Clifford algebras, but simply by generalizing the usual spinless theory. We only assume the invariance with respect to the Poincare' group; and only requiring the conservation of the linear and angular momenta we derive the zitterbewegung: namely the decomposition of the 4-velocity in the newtonian constant term p/m and in a non-newtonian time-oscillating spacelike term. Consequently, free classical particles do not obey, in general, the Principle of Inertia. Superluminal motions are also allowed, without violating Special Relativity, provided that the energy-momentum moves along the worldline of the center-of-mass. Moreover, a non-linear, non-constant relation holds between the time durations measured in different reference frames. Newtonian Mechanics is re-obtained as a particular case of the present theory: namely for spinless systems with no zitterbewegung. Introducing a Lagrangian containing also derivatives of the 4-velocity we get a new equation of the motion, actually a generalization of the Newton Law a=F/m. Requiring the rotational symmetry and the reparametrization invariance we derive the classical spin vector and the conserved scalar Hamiltonian, respectively. We derive also the classical Dirac spin and analyze the general solution of the Eulero-Lagrange equation for Dirac particles. The interesting case of spinning systems with zero intrinsic angular momentum is also studied.

description: The amount of agricultural land available in developed countries is decreasing by a degree which may profoundly affect in the long term the food security. This paper reports a quantitative investigation of the factors that contribute to this decrease, by analysing 30 countries during the period 1995-2009. The panel data analysis suggests that a variety of phenomena are associated with the decline in agricultural land: a high level of gross domestic product, an increase in the size of urban areas and transport networks, and an increase in agricultural productivity. This last factor is linked to the abandonment of the least productive plots of land and to its conversion to forest. In contrast, an higher quality of institutions is associated with a reduction in the rate of cropland loss. This suggests that a qualitative growth in institutional quality determines a greater attention to agricultural land as a resource for the supply of food products and environmental services.
