description: Background: Hereditary transthyretin amyloidosis (ATTR) is a multisystemic disease involving mainly the peripheral nervous system and the heart. Liver transplantation (LT) is the reference treatment for ATTR neuropathy and preoperative detection of high risk patients is crucial. We aimed to document the causes of death of ATTR patients after LT, their temporal trends, and to evaluate whether the available preoperative tools that predict the risk of death after LT for hereditary ATTR amyloidosis matched with these trends. Methods: A retrospective longitudinal cohort study was performed on 215 consecutive ATTR patients who underwent LT between January 1993 and January 2011. Each patient’s death cause and timing were classified. Results: Over a median follow up of 5.9 years, 84 patients died. The rate of death was higher in the first year following LT than thereafter (13.0 vs. 4.3 ± 1.8%/year; p = .004). Cardiac events ranked as the leading cause of death (C: 38%), followed by infections (I: 24%), graft complications (G: 17%), end stage amyloidosis, stroke and others (ASO: 7% each). Deaths due to graft complications and infections (GI) occurred earlier than those due to end stage amyloidosis and stroke. Death prediction was less accurate for GI-related mortality than for other causes, which blunted the accuracy of the early-term risk prediction scores. Conclusions In ATTR amyloidosis, cardiac events were the leading cause of death after liver transplantation. Close preoperative evaluation allowed for accurate mid-term prediction of mortality, but the high rate of graft complications and infections blunted the early-term risk prediction.

description: This paper presents the first classical Convolutional Neural Network (CNN) that can be applied directly to data from unstructured finite element meshes or control volume grids. CNNs have been hugely influential in the areas of image classification and image compression, both of which typically deal with data on structured grids. Unstructured meshes are frequently used to solve partial differential equations and are particularly suitable for problems that require the mesh to conform to complex geometries or for problems that require variable mesh resolution. Central to the approach are space-filling curves, which traverse the nodes or cells of a mesh tracing out a path that is as short as possible (in terms of numbers of edges) and that visits each node or cell exactly once. The space-filling curves (SFCs) are used to find an ordering of the nodes or cells that can transform multi-dimensional solutions on unstructured meshes into a one-dimensional (1D) representation, to which 1D convolutional layers can then be applied. Although developed in two dimensions, the approach is applicable to higher dimensional problems.
 To demonstrate the approach, the network we choose is a convolutional autoencoder (CAE) although other types of CNN could be used. The approach is tested by applying CAEs to data sets that have been reordered with an SFC. Sparse layers are used at the input and output of the autoencoder, and the use of multiple SFCs is explored. We compare the accuracy of the SFC-based CAE with that of a classical CAE applied to two idealised problems on structured meshes, and then apply the approach to solutions of flow past a cylinder obtained using the finite-element method and an unstructured mesh.

description: When selling information products, the seller can provide some free partial information to change people's valuations so that the overall revenue can possibly be increased. We study the general problem of advertising information products by revealing partial information. We consider buyers who are decision-makers. The outcomes of the decision problems depend on the state of the world that is unknown to the buyers. The buyers can make their own observations and thus can hold different personal beliefs about the state of the world. There is an information seller who has access to the state of the world. The seller can promote the information by revealing some partial information. We assume that the seller chooses a long-term advertising strategy and then commits to it. The seller's goal is to maximize the expected revenue. We study the problem in two settings. (1) The seller targets buyers of a certain type. In this case, finding the optimal advertising strategy is equivalent to finding the concave closure of a simple function. The function is a product of two quantities, the likelihood ratio and the cost of uncertainty. Based on this observation, we prove some properties of the optimal mechanism, which allow us to solve for the optimal mechanism by a finite-size convex program. The convex program will have a polynomial-size if the state of the world has a constant number of possible realizations or the buyers face a decision problem with a constant number of options. For the general problem, we prove that it is NP-hard to find the optimal mechanism. (2) When the seller faces buyers of different types and only knows the distribution of their types, we provide an approximation algorithm when it is not too hard to predict the possible type of buyers who will make the purchase. For the general problem, we prove that it is NP-hard to find a constant-factor approximation.

description: The effects of a world oil price shock on U.S. agriculture are analyzed in an economywide environment. We use an input-output model to analyze the direct and indirect cost linkages between energy and other sectors of the economy. Then, to allow sectoral output adjustment and the effects on the U.S. current account, we use the U.S. Department of Agriculture/Economic Research Service Computable General Equilibrium (CGE) model to analyze the sectoral effects under three different macro adjustment scenarios. Theeffects on agriculture are not limited to the direct and indirect energy costs. Exchange rate or foreign borrowing adjustments to higher oil import costs and government support programs for agriculture also matter.

description: Given a Bell inequality, if its maximal quantum violation can be achieved only by a single set of measurements for each party or a single quantum state, up to local unitaries, one refers to such a phenomenon as self-testing. For instance, the maximal quantum violation of the Clauser-Horne-Shimony-Holt inequality certifies that the underlying state contains the two-qubit maximally entangled state and the measurements of one party contains a pair of anti-commuting qubit observables. As a consequence, the other party automatically verifies the set of states remotely steered, namely the "assemblage", is in the eigenstates of a pair of anti-commuting observables. It is natural to ask if the quantum violation of the Bell inequality is not maximally achieved, or if one does not care about self-testing the state or measurements, are we capable of estimating how close the underlying assemblage is to the reference one? In this work, we provide a systematic device-independent estimation by proposing a framework called "robust self-testing of steerable quantum assemblages". In particular, we consider assemblages violating several paradigmatic Bell inequalities and obtain the robust self-testing statement for each scenario. Our result is device-independent (DI), i.e., no assumption is made on the shared state and the measurement devices involved. Our work thus not only paves a way for exploring the connection between the boundary of quantum set of correlations and steerable assemblages, but also provides a useful tool in the areas of DI quantum certification. As two explicit applications, we show 1) that it can be used for an alternative proof of the protocol of DI certification of all entangled two-qubit states proposed by Bowles et al., and 2) that it can be used to verify all non-entanglement-breaking qubit channels with fewer assumptions compared with the work of Rosset et al.

description: We present an overview of the occurrence and properties of atomic gas associated with compact radio sources at redshifts up to z=0.85. Searches for HI 21cm absorption were made with the Westerbork Synthesis Radio Telescope at UHF-high frequencies (725-1200 MHz). Detections were obtained for 19 of the 57 sources with usable spectra (33%). We have found a large range in line depths, from tau=0.16 to tau<=0.001. There is a substantial variety of line profiles, including Gaussians of less than 10km/s, to more typically 150km/s, as well as irregular and multi-peaked absorption profiles, sometimes spanning several hundred km/s. Assuming uniform coverage of the entire radio source, we obtain column depths of atomic gas between 1e19 and 3.3e21(Tsp/100K)(1/f)cm^(-2). There is evidence for significant gas motions, but in contrast to earlier results at low redshift, there are many sources in which the HI velocity is substantially negative (up to v=-1420km/s) with respect to the optical redshift, suggesting that in these sources the atomic gas, rather than falling into the centre, may be be flowing out, interacting with the jets, or rotating around the nucleus.

description: We present a novel approach for unsupervised road segmentation in adverse weather conditions such as rain or fog. This includes a new algorithm for source-free domain adaptation (SFDA) using self-supervised learning. Moreover, our approach uses several techniques to address various challenges in SFDA and improve performance, including online generation of pseudo-labels and self-attention as well as use of curriculum learning, entropy minimization and model distillation. We have evaluated the performance on $6$ datasets corresponding to real and synthetic adverse weather conditions. Our method outperforms all prior works on unsupervised road segmentation and SFDA by at least 10.26%, and improves the training time by 18-180x. Moreover, our self-supervised algorithm exhibits similar accuracy performance in terms of mIOU score as compared to prior supervised methods.

description: Land leasing plays a vital role in U.S. agriculture, allowing landlords to receive monetary returns from land they do not wish to operate, and allowing tenants to acquire use rights to land. Agricultural leasing is no longer seen as a temporary step toward full ownership, but as an effective way to gain control of land resources. Leasing can be used to expand or contract the farm operation, to conserve limited capital for financing farm operations, to enhance management flexibility, and to reduce risk. This report examines the extent of agricultural leasing, the characteristics of owners who lease land to others, and the nature of leasing arrangements. It is based on the data file of the 1988 Agricultural Economics and Land Ownership Survey (AELOS), a follow-on to the 1987 Census of Agriculture. AELOS provides information on the ownership of land held by operators and nonoperators of farms.

description: Due to the outstanding capability of capturing underlying data distributions, deep learning techniques have been recently utilized for a series of traditional database problems. In this paper, we investigate the possibilities of utilizing deep learning for cardinality estimation of similarity selection. Answering this problem accurately and efficiently is essential to many data management applications, especially for query optimization. Moreover, in some applications the estimated cardinality is supposed to be consistent and interpretable. Hence a monotonic estimation w.r.t. the query threshold is preferred. We propose a novel and generic method that can be applied to any data type and distance function. Our method consists of a feature extraction model and a regression model. The feature extraction model transforms original data and threshold to a Hamming space, in which a deep learning-based regression model is utilized to exploit the incremental property of cardinality w.r.t. the threshold for both accuracy and monotonicity. We develop a training strategy tailored to our model as well as techniques for fast estimation. We also discuss how to handle updates. We demonstrate the accuracy and the efficiency of our method through experiments, and show how it improves the performance of a query optimizer.

description: We propose a simple scheme for complete Bell-state measurement of photons using hyperentangled states - entangled in multiple degrees of freedom. In addition to hyperentanglement, our scheme requires only linear optics and single photon detectors, and is realizable with current technology. At the cost of additional classical communication, our Bell-state measurement can be implemented non-locally. We discuss the possible application of these results to quantum dense coding and quantum teleportation.

description: Objective: To evaluate the utility of Sudoscan as possible marker of disease progression and disease onset in a cohort of hereditary ATTR amyloidosis (hATTR amyloidosis) polyneuropathy patients and carriers. Patients and methods: We regularly performed different clinical scales, nerve conductions studies (NCS), and Sudoscan on a cohort of hATTR amyloidosis patients and carriers from a single centre of central Italy, a non-endemic area, in the last 2 years. Results: About 18 hATTR amyloidosis patients and 8 asymptomatic carriers were enrolled. All patients had a neuropathy affecting large fibres, small fibres or both. Two subjects developed symptoms and neurophysiological alterations during follow-up. Sudoscan data from hand and feet inversely correlated with neuropathy severity and with disease duration. Moreover, global disease status, expressed by Kumamoto scale also inversely correlated with Sudoscan values. Conclusions: We confirmed that Sudoscan is a reliable marker of disease progression in late-onset hATTR amyloidosis patients and we suggest its possible utility in early detection of disease in this population.

Our previous study in which the lattices are calibrated with a few percent accuracy has already given results comparable to the existing calculations. This suggests that even higher precision may be achieved by a more precise calibration of anisotropic lattices. We describe our strategy to tune the gauge and quark parameters with accuracies much less than 1 % in the quenched approximation.

description: Much of the Farmers Home Administration's (FmHA) credit assistance to farmers now comes through loans made by commercial or cooperative lenders, but guaranteed against default losses by FmHA. Lenders and borrowers that participated in the guaranteed farm loan programs during fiscal 1988, along with characteristics of the loans themselves, are extensively profiled for the first time. Results indicate that loan guarantee programs generally serve large family farms that are highly indebted and are much more likely to fail than the average farm. Most loan guarantees are issued to existing customers and not to new customers, but interest rates and terms charged on these loans are consistent with rates and terms experienced by other farm borrowers. Considerable regional variation in the characteristics of program participants exists. Results have implications for the new secondary market for farm loan guarantees and in the graduation of FmHA's direct loan borrowers to guaranteed loan programs.

description: The unremitting pursuit for quantum advantages gives rise to the discovery of a quantum-enhanced randomness processing named quantum Bernoulli factory (QBF). This quantum enhanced process can show its priority over the corresponding classical process through readily available experimental resources, thus in the near term it may be capable of accelerating the applications of classical Bernoulli factories, such as the widely used sampling algorithms. In this work, we provide the framework analysis of the QBF. We thoroughly analyze the quantum state evolution in this process, discovering the field structure of the constructible quantum states. Our framework analysis shows that naturally, the previous works can be described as specific instances of this framework. Then, as a proof of principle, we experimentally demonstrate this framework via an entangled two-photon source along with a reconfigurable photonic logic, and show the advantages of the QBF over the classical model through a classically infeasible instance. These results may stimulate the discovery of advantages of the quantum randomness processing in a wider range of tasks, as well as its potential applications.

description: (ABRIDGED) We present a semi-analytic model to explore merger histories, destruction rates, and survival probabilities of substructure in dark matter halos and use it to study the substructure populations of galaxy-sized halos as a function of the power spectrum. We successfully reproduce the subhalo velocity function and radial distribution seen in N-body simulations for standard LCDM. We explore the implications of spectra with normalizations and tilts spanning sigma_8 = 0.65-1 and n = 0.8-1. We also study a running index (RI) model with dn/dlnk=-0.03, as discussed in the first year WMAP report, and several WDM models with masses m_W = 0.75, 1.5, 3.0 keV. The substructure mass fraction is relatively insensitive to the tilt and overall normalization of the power spectrum. All CDM-type models yield projected substructure mass fractions that are consistent with, but on the low side of, estimates from strong lens systems: f = 0.4-1.5% (64 percentile) in systems M_sub < 10^9 Msun. Truncated models produce significantly smaller fractions and are disfavored by lensing results. We compare our predicted subhalo velocity functions to the dwarf satellite population of the Milky Way. Assuming isotropic velocity dispersions, we find the standard n=1 model overpredicts the number of MW satellites as expected. Models with less small-scale power are more successful because there are fewer subhalos of a given circular velocity and the mapping between observed velocity dispersion and halo circular velocity is markedly altered. The RI model, or a fixed tilt with sigma_8=0.75, can account for the MW dwarfs without the need for differential feedback; however, these comparisons depend sensitively on the assumption of isotropic velocities in satellite galaxies.

description: In genetic networks, information of relevance to the organism is represented by the concentrations of transcription factor molecules. In order to extract this information the cell must effectively "measure"' these concentrations, but there are physical limits to the precision of these measurements. We explore this trading between bits of precision in measuring concentration and bits of relevant information that can be extracted, using the gap gene network in the early fly embryo as an example. We argue that cells in the embryo can extract all the available information about their position, but only if the concentration measurements approach the physical limits to information capacity. These limits necessitate the observed proliferation of enhancer elements with sensitivities to combinations of transcription factors, but fine tuning of the parameters of these multiple enhancers is not required.

A high proportion of IgM+ MALT lymphoma cases were found to bear genetic alterations in the switch regions. Most of these switch region genetic alterations have been characterized through molecular cloning as chromosomal insertions and internal deletions but no new gene has been identified. Variable regions analysis revealed the presence of somatic hypermutations in all cases and intraclonal variation in a proportion of these. Correlation of somatic hypermutations and intraclonal variation with switch region alterations raised the possibility of two distinct subsets of MALT lymphoma with different maturation: one subset with aberrant isotype switch and no intraclonal diversification, and the other one with no aberrant isotype switch but with intraclonal diversification. Replacement versus silent mutation ratio analysis of complementarity-determining regions and frameworks indicated the positive selective pressure of an antigen in most cases. In two cases, protein translated from the third complementarity-determining region suggested the selective pressure of an autoantigen. A correlation of switch region alterations with clinical behaviour revealed that cases with rearrangements have a longer disease-free time after gastrectomy.

In B-CLL switch region analysis demonstrated the presence of switch region alterations in a proportion of cases (34%). These alterations are in most cases internal deletions of the switch mu region and their role remains to be determined although their localization in the VhDJh rearranged alleles suggests a role in the stabilization of the isotype of the expressed immunoglobulin. Variable regions analysis showed somatic hypermutations in a proportion of cases and no correlation with switch region deletions was detected. No significant correlation between switch region deletions and prognosis was observed, indicating that internal deletions have no consequence for disease outcome. Moreover no significant correlation between the presence of switch deletions and somatic hypermutations was found, indicating that the two processes giving rise to internal deletions and somatic hypermutations, are independent in B-CLL.

A spin metal-oxide-semiconductor field-effect transistor using half-metallic-ferromagnet contacts for the source and drain

description: We propose and theoretically analyze a novel metal-oxide-semiconductor field-effect-transistor (MOSFET) type of spin transistor (hereafter referred to as a spin MOSFET) consisting of a MOS gate structure and half-metallic-ferromagnet (HMF) contacts for the source and drain. When the magnetization configuration between the HMF source and drain is parallel (antiparallel), highly spin-polarized carriers injected from the HMF source to the channel are transported into (blocked by) the HMF drain, resulting in the magnetization-configuration-dependent output characteristics. Our two-dimensional numerical analysis indicates that the spin MOSFET exhibits high (low) current drive capability in the parallel (antiparallel) magnetization, and that extremely large magnetocurrent ratios can be obtained. Furthermore, the spin MOSFET satisfies other important requirements for "spintronic" integrated circuits, such as high amplification capability, low power-delay product, and low off-current.

description: We study calibration procedures of the staggered quarks on anisotropic lattices in the quenched approximation and in $N_f = 2$ dynamical simulations. For the calibration conditions we adopt the hadronic radii $r_0$ and the meson masses in the temporal and spatial directions. On the quenched lattice, we calibrate the quark field and compare the result with the result determined using the meson dispersion relation. In dynamical simulations, we determine the anisotropy parameters $γ_G$ and $γ_F$ simultaneously within 1% accuracy at renormalized anisotropy $ξ= a_s/a_t = 4$.

description: In this note, we construct an algorithm that, on input of a description of a structurally stable planar dynamical flow $f$ defined on the closed unit disk, outputs the exact number of the (hyperbolic) equilibrium points and their locations with arbitrary accuracy. By arbitrary accuracy it is meant that any accuracy required by the input can be achieved. The algorithm can be further extended to a root-finding algorithm that computes the exact number of zeros as well the location of each zero of a continuously differentiable function $f$ defined on the closed unit ball of $\mathbb{R}^{d}$, provided that the Jacobian of $f$ is invertible at each zero of $f$; moreover, the computation is uniform in $f$.

description: Analisa-se a obra de Sanches, Antunes e Lopes (2019) que, começando por abordar os conceitos subjacentes ao referencial teórico relativo ao desenvolvimento da escrita em contexto académico, nos convida a reflectir sobre o impacto que a regularidade desta prática pode ter no sucesso académico dos estudantes do ensino superior. Apresenta-se, ainda, a noção de que as competências associadas ao planeamento, orientação, divulgação e análise da informação científica assentam em saber ler de forma cuidada, em pensar correctamente, em argumentar de modo lógico e em escrever claramente, o que, na obra em análise, os autores consideram constituir condição basilar para a transferência do conhecimento. Conclui-se procedendo à abordagem da implicação e desafio que essas condições formativas constituem para a capacidade de comunicar ciência através de uma nova estrutura arquitectónica e morfológica que, se bem que tradicionalmente já existente, desafia agora os autores, mas também os docentes e os bibliotecários, acrescentado que foi o novo e disruptivo paradigma de publicação em modelos associados à Ciência Aberta.

description: We present our library for Universal Algebra in the UniMath framework dealing with multi-sorted signatures, their algebras, and the basics for equation systems. We show how to implement term algebras over a signature without resorting to general inductive constructions (currently not allowed in UniMath) still retaining the computational nature of the definition. We prove that our single sorted ground term algebras are instances of homotopy W-types. From this perspective, the library enriches UniMath with a computationally well-behaved implementation of a class of W-types. Moreover, we give neat constructions of the univalent categories of algebras and equational algebras by using the formalism of displayed categories, and show that the term algebra over a signature is the initial object of the category of algebras. Finally, we showcase the computational relevance of our work by sketching some basic examples from algebra and propositional logic.

description: This paper explores the impact of the rapid energy price increases during the 1970's on beef production and prices in Hawaii by performing two simulations‘ of a quarterly econometric model of the Hawaii beef industry. With energy prices increasing at pre-oil embargo rates, Hawaii could have produced 37 percent more grain-fed beef and 46 percent less grass-fed beef in 1980, for an increase in total beef production of 7 percent.

description: For each positive integer $t$ and each sufficiently large integer $r$, we show that the maximum number of elements of a simple, rank-$r$, $\mathbb C$-representable matroid with no $U_{2,t+3}$-minor is $t{r\choose 2}+r$. We derive this as a consequence of a much more general result concerning matroids on group-labeled graphs.

Intermittency and regularity issues in 3D Navier-Stokes turbulence

description: Two related open problems in the theory of 3D Navier-Stokes turbulence are discussed in this paper. The first is the phenomenon of intermittency in the dissipation field. Dissipation-range intermittency was first discovered experimentally by Batchelor and Townsend over fifty years ago. It is characterized by spatio-temporal binary behaviour in which long, quiescent periods in the velocity signal are interrupted by short, active `events' during which there are violent fluctuations away from the average. The second and related problem is whether solutions of the 3D Navier-Stokes equations develop finite time singularities during these events. This paper shows that Leray's weak solutions of the three-dimensional incompressible Navier-Stokes equations can have a binary character in time. The time-axis is split into `good' and `bad' intervals: on the `good' intervals solutions are bounded and regular, whereas singularities are still possible within the `bad' intervals. An estimate for the width of the latter is very small and decreases with increasing Reynolds number. It also decreases relative to the lengths of the good intervals as the Reynolds number increases. Within these `bad' intervals, lower bounds on the local energy dissipation rate and other quantities, such as $\|\bu(\cdot, t)\|_{\infty}$ and $\|\nabla\bu(\cdot, t)\|_{\infty}$, are very large, resulting in strong dynamics at sub-Kolmogorov scales. Intersections of bad intervals for $n\geq 1$ are related to Scheffer's potentially singular set in time. It is also proved that the Navier-Stokes equations are conditionally regular provided, in a given `bad' interval, the energy has a lower bound that is decaying exponentially in time.
