description: We present a family of alchemical perturbation potentials that enable the calculation of hydration free energies of small to medium-sized molecules in a concerted single alchemical coupling step instead of the commonly used sequence of two distinct coupling steps for Lennard-Jones and electrostatic interactions. The perturbation potentials are based on the softplus function of the solute-solvent interaction energy designed to focus sampling near entropic bottlenecks along the alchemical pathway. We present a general framework to optimize the parameters of alchemical perturbation potentials of this kind. The optimization procedure is based on the $λ$-function formalism and the maximum-likelihood parameter estimation procedure we developed earlier to avoid the occurrence of multi-modal distributions of the coupling energy along the alchemical path. A novel soft-core function applied to the overall solute-solvent interaction energy rather than individual interatomic pair potentials critical for this result is also presented. Because it does not require modifications of core force and energy routines, the soft-core formulation can be easily deployed in molecular dynamics simulation codes. We illustrate the method by applying it to the estimation of the hydration free energy in water droplets of compounds of varying size and complexity. In each case, we show that convergence of the hydration free energy is achieved rapidly. This work paves the way for the ongoing development of more streamlined algorithms to estimate free energies of molecular binding with explicit solvation.

description: Japanese rural areas are running short of farmers who can accept farmland from the retired farmers, and the amount of the abandoned farmland is increasing. Under these circumstances, the number of the special subsidiary companies which have expanded their business to agriculture has been increasing, and it will go on. If these new type special subsidiary companies can overcome their weaknesses in their agricultural business, they will become the farms which can support the regional agriculture where they are located because they have the better manpower (includes employed persons with disabilities) and many strengths, compared with the social-welfare corporations which have expanded their business to agriculture. If the special subsidiary companies can establish good relationships in their agricultural business with the farmers and the social-welfare corporations which belong to their regional areas, they will have possibilities to play important roles in the regional economics and the regional communities where they are located.

description: The ongoing COVID-19 pandemic has overwhelmingly demonstrated the need to accurately evaluate the effects of implementing new or altering existing nonpharmaceutical interventions. Since these interventions applied at the societal level cannot be evaluated through traditional experimental means, public health officials and other decision makers must rely on statistical and mathematical epidemiological models. Nonpharmaceutical interventions are typically focused on contacts between members of a population, and yet most epidemiological models rely on homogeneous mixing which has repeatedly been shown to be an unrealistic representation of contact patterns. An alternative approach is individual based models (IBMs), but these are often time intensive and computationally expensive to implement, requiring a high degree of expertise and computational resources. More often, decision makers need to know the effects of potential public policy decisions in a very short time window using limited resources. This paper presents an estimation algorithm for an IBM designed to evaluate nonpharmaceutical interventions. By utilizing recursive relationships, our method can quickly compute the expected epidemiological outcomes even for large populations based on any arbitrary contact network. We utilize our methods to evaluate the effects of relaxing current social distancing measures in Iowa, USA, at various times and to various degrees. \verb!R! code for our method is provided in the supplementary material, thereby allowing others to utilize our approach for other regions.

description: This paper presents a convolutional neural network (CNN)-based enhancement to inter prediction in Versatile Video Coding (VVC). Our approach aims at improving the prediction signal of inter blocks with a residual CNN that incorporates spatial and temporal reference samples. It is motivated by the theoretical consideration that neural network-based methods have a higher degree of signal adaptivity than conventional signal processing methods and that spatially neighboring reference samples have the potential to improve the prediction signal by adapting it to the reconstructed signal in its immediate vicinity. We show that adding a polyphase decomposition stage to the CNN results in a significantly better trade-off between computational complexity and coding performance. Incorporating spatial reference samples in the inter prediction process is challenging: The fact that the input of the CNN for one block may depend on the output of the CNN for preceding blocks prohibits parallel processing. We solve this by introducing a novel signal plane that contains specifically constrained reference samples, enabling parallel decoding while maintaining a high compression efficiency. Overall, experimental results show average bit rate savings of 4.07% and 3.47% for the random access (RA) and low-delay B (LB) configurations of the JVET common test conditions, respectively.

description: Hamiltonian diagonalization is at the heart of understanding physical properties and practical applications of quantum systems. It is highly desired to design quantum algorithms that can speedup Hamiltonian diagonalization, especially those can be implemented on near-term quantum devices. In this work, we propose a variational algorithm for Hamiltonians diagonalization (VQHD) of quantum systems, which explores the important physical properties, such as temperature, locality and correlation, of the system. The key idea is that the thermal states of the system encode the information of eigenvalues and eigenstates of the system Hamiltonian. To obtain the full spectrum of the Hamiltonian, we use a quantum imaginary time evolution algorithm with high temperature, which prepares a thermal state with a small correlation length. With Trotterization, this then allows us to implement each step of imaginary time evolution by a local unitary transformation on only a small number of sites. Diagonalizing these thermal states hence leads to a full knowledge of the Hamiltonian eigensystem. We apply our algorithm to diagonalize local Hamiltonians and return results with high precision. Our VQHD algorithm sheds new light on the applications of near-term quantum computers.

description: Citrus unshiu farming has been assumed to be hard to develop on large-scale farms because of its labor intensive technical character, which makes mid-sized farms is superior to large farms. However large-size citrus farms are developing in Mikkabi, Shizuoka Prefecture, where improvement of production infrastructure is most advanced and market competitiveness in citrus unshiu has been strong. Therefore the technical systems in Mikkabi which have supported development of large-scale citrus unshiu farming were analyzed by a farm survey. Though mid-sized farms, which are within the existing appropriate farm size, are superior to large farms in land productivity, large farms, which for the most part exceed the existing appropriate size, are superior to mid-sized farms in labor productivity. The large farms have achieved high productivity by the introduction of technology which makes best use of improved production infrastructure such as mechanization and mulching cultivation, adoption of quality improvement technology such as mulching cultivation, and input of a large amount of hired labor.

description: With the rapid development of smart cities, smart buildings are generating a massive amount of building sensing data by the equipped sensors. Indeed, building sensing data provides a promising way to enrich a series of data-demanding and cost-expensive urban mobile applications. In this paper, we study how to reuse building sensing data to predict traffic volume on nearby roads. Nevertheless, it is non-trivial to achieve accurate prediction on such cross-domain data with two major challenges. First, relationships between building sensing data and traffic data are not unknown as prior, and the spatio-temporal complexities impose more difficulties to uncover the underlying reasons behind the above relationships. Second, it is even more daunting to accurately predict traffic volume with dynamic building-traffic correlations, which are cross-domain, non-linear, and time-varying. To address the above challenges, we design and implement BuildSenSys, a first-of-its-kind system for nearby traffic volume prediction by reusing building sensing data. First, we conduct a comprehensive building-traffic analysis based on multi-source datasets, disclosing how and why building sensing data is correlated with nearby traffic volume. Second, we propose a novel recurrent neural network for traffic volume prediction based on cross-domain learning with two attention mechanisms. Specifically, a cross-domain attention mechanism captures the building-traffic correlations and adaptively extracts the most relevant building sensing data at each predicting step. Then, a temporal attention mechanism is employed to model the temporal dependencies of data across historical time intervals. The extensive experimental studies demonstrate that BuildSenSys outperforms all baseline methods with up to 65.3% accuracy improvement (e.g., 2.2% MAPE) in predicting nearby traffic volume.

description: Backgrounds depending on time and on "angular" variable, namely polarized and unpolarized $S^1 \times S^2$ Gowdy models, are generated as the sector inside the horizons of the manifold corresponding to axisymmetric solutions. As is known, an analytical continuation of ordinary $D$-branes, $iD$-branes allows one to find $S$-brane solutions. Simple models have been constructed by means of analytic continuation of the Schwarzchild and the Kerr metrics. The possibility of studying the $i$-Gowdy models obtained here is outlined with an eye toward seeing if they could represent some kind of generalized $S$-branes depending not only on time but also on an ``angular'' variable.

description: In the early 1970s, the midpoint of this academic society's history, the "excessive employment" in Japanese agriculture was one of the most important research subjects. Recent studies of Southeast Asian agriculture, which followed the empirical methods of investigation of the Japanese case, revealed the existence of contrasting mechanisms of wage determination. In Java, wage is determined as the average labor productivity by the work-sharing principle. Contrastively in Central Thailand, wage is determined as the marginal productivity by bilateral contracts in the market principle. In the light of the contemporary trend toward economic globalization, our next task of investigation should be why and how these contrasting systems and diversity of agrarian structure come about and coexist in the world.

description: In this work, full triazine two-dimensional frameworks (2DC3N3) were synthesized and used to detect metal ions in aqueous solutions. 2DC3N3 showed excellent performance to sense Hg(II) with high selectivity (>96%) and was designed as a recyclable sensor for Hg(II) detection. 2DC3N3 was synthesized using catalyst-free [2+2+2] cyclotrimerization of sodium cyanide and cyanuric chloride at ambient conditions. The as-prepared 2DC3N3 sheets with several hundred micrometers lateral size exhibited strong excitation-dependent fluorescence with 63% quantum yield and maximum emission at 428 nm. The emission of 2DC3N3 decreased with 14.74 × 103 L·mol–1 quenching constant (KSV) upon interaction with Hg2+ ions. This effect was used as a strong signal to detect Hg(II) with a 0.98 nM detection limit. The high Hg2+ removal capacity of 2DC3N3 was attributed to cooperative interactions of nitrogen atoms of 2DC3N3 pores and Hg2+, as suggested by computational studies. Taking advantage of the straightforward synthesis of 2DC3N3 and its selectivity, it can be used as an efficient platform for monitoring Hg2+ in waste and drinking water.

description: We report the result of searching for globular clusters (GCs) around 55 Milky Way satellite dwarf galaxies within the distance of 450 kpc from the Galactic Center except for the Large and Small Magellanic Clouds and the Sagittarius dwarf. For each dwarf, we analyze the stellar distribution of sources in Gaia DR2, selected by magnitude, proper motion, and source morphology. Using the kernel density estimation of stellar number counts, we identify eleven possible GC candidates. Crossed-matched with existing imaging data, all eleven objects are known either GCs or galaxies and only Fornax GC 1-6 among them are associated with the targeted dwarf galaxy. Using simulated GCs, we calculate the GC detection limit $M_{\rm V}^{\rm lim}$ that spans the range from $M_{\rm V}^{\rm lim} \sim -7$ for distant dwarfs to $M_{\rm V}^{\rm lim} \sim 0$ for nearby systems. Assuming a Gaussian GC luminosity function, we compute that the completeness of the GC search is above 90 percent for most dwarf galaxies. We construct the 90 percent credible intervals/upper limits on the GC specific frequency $S_{\rm N}$ of the MW dwarf galaxies: $12 < S_{\rm N} < 47$ for Fornax, $S_{\rm N} < 20$ for the dwarfs with $-12 < M_{\rm V} < -10$, $S_{\rm N} < 30$ for the dwarfs with $-10 < M_{\rm V} < -7$, and $S_{\rm N} < 90$ for the dwarfs with $M_{\rm V} > -7$. Based on $S_{\rm N}$, we derive the probability of galaxies hosting GCs given their luminosity, finding that the probability of galaxies fainter than $M_{\rm V} = -9$ to host GCs is lower than 0.1.

description: We previously reported that Aurora-A and the hNinein binding protein AIBp facilitate centrosomal structure maintenance and contribute to spindle formation. Here, we report that AIBp also interacts with Plk1, raising the possibility of functional similarity to Bora, which subsequently promotes Aurora-A–mediated Plk1 activation at Thr210 as well as Aurora-A activation at Thr288. In kinase assays, AIBp acts not only as a substrate but also as a positive regulator of both Aurora-A and Plk1. However, AIBp functions as a negative regulator to block phosphorylation of hNinein mediated by Aurora-A and Plk1. These findings suggest a novel AIBp-dependent regulatory machinery that controls mitotic entry. Additionally, knockdown of hNinein caused failure of AIBp to target the centrosome, whereas depletion of AIBp did not affect the localization of hNinein and microtubule nucleation. Notably, knockdown of AIBp in HeLa cells impaired both Aurora-A and Plk1 kinase, resulting in phenotypes with multiple spindle pole formation and chromosome misalignment. Our data show that depletion of AIBp results in the mis-localization of TACC3 and ch-TOG, but not CEP192 and CEP215, suggesting that loss of AIBp dominantly affects the Aurora-A substrate to cause mitotic aberrations. Collectively, our data demonstrate that AIBp contributes to mitotic entry and bipolar spindle assembly and may partially control localization, phosphorylation, and activation of both Aurora-A and Plk1 via hNinein during mitotic progression.

description: Due to the capability of tolerating high error rate and generating more key bits per trial, high-dimensional quantum key distribution attracts wide interest. Despite great progresses in high-dimensional quantum key distribution, there are still some gaps between theory and experiment. One of these is that the security of the secret key heavily depends on the number of the emitted signals. So far, the existing security proofs are only suitable in the case with an infinite or unpractically large number of emitted signals. Here, by introducing the idea of "key classification" and developing relevant techniques based on the uncertainty relation for smooth entropies, we propose a tight finite-key analysis suitable for generalized high-dimensional quantum key distribution protocols. Benefitting from our theory, high-dimensional quantum key distribution protocols with finite resources become experimentally feasible.

description: Ion-implantation of normally insulating polymers offers an alternative to depositing conjugated organics onto plastic films to make electronic circuits. We used a 50 keV nitrogen ion beam to mix a thin 10 nm Sn/Sb alloy film into the sub-surface of polyetheretherketone (PEEK) and report the low temperature properties of this material. We observed metallic behavior, and the onset of superconductivity below 3 K. There are strong indications that the superconductivity does not result from a residual thin-film of alloy, but instead from a network of alloy grains coupled via a weakly conducting, ion-beam carbonized polymer matrix.

title: Comparative and Functional Genomic Analysis of Streptococcus Equi and Streptococcus Zooepidemicus : Identifying Novel Vaccine Targets
Creators: name: Heather, Zoe
Publisher: name: The Open University
Year: 2009

description: Streptococcus equi subspecies equi (S. equi) is a host-restricted pathogen of horses and the aetiological agent of strangles. Available evidence suggests that S. equi evolved from Streptococcus equi subspecies zooepidemicus (S. zooepidemicus), a versatile bacterium that is often isolated from the equine respiratory tract, but can cause opportunistic disease in horses and other animals. A comparison of the genomes of S. equi 4047 and S. zooepidemicus H70 and the screening of diverse S. equi and S. zooepidemicus strains uncovered the genetic events that have shaped the evolution of S. equi, and led to its emergence as a niche-adapted pathogen. This analysis provides evidence of functional loss, changes in the organisation and sequence of genes, and pathogenic specialisation through the acquisition of prophage encoding a phospholipase A2 toxin, and 4 superantigens, and an integrative conjugative element carrying a novel siderophore-like nonribosomal peptide synthetase (NRPS) system. The NRPS shares similarity with the yersiniabactin system found in the high pathogenicity island of Yersinia pestis and is the first of its kind to be identified in streptococci. As this genetic feature is absent from the S. zooepidemicus population, its gain is considered to have been a key event in the emergence of S. equi. Further work determined a role for the NRPS in iron acquisition, and through its heterologous reconstitution in Escherichia coli and/or the analysis of allelic replacement mutants in S. equi, identified biosynthetic genes, transporters involved in efflux and import of the NRPS product(s), salicylate as a substrate for the NRPS and its regulation by a novel iron-dependent IdeR-like repressor, using various in vitro growth assays, including sensitivity to streptonigrin and 55Fe accumulation. Possible vaccine targets were identified in both subspecies and existing diagnostic tools were improved, which included the development of a quantitative PCR test for the detection of S. equi.

description: We study coherent states for Bianchi type I cosmological models, as examples of semiclassical states for time-reparametrization invariant systems. This simple model allows us to study explicitly the relationship between exact semiclassical states in the kinematical Hilbert space and corresponding ones in the physical Hilbert space, which we construct here using the group averaging technique. We find that it is possible to construct good semiclassical physical states by such a procedure in this model; we also discuss the sense in which the original kinematical states may be a good approximation to the physical ones, and the situations in which this is the case. In addition, these models can be deparametrized in a natural way, and we study the effect of time evolution on an "intrinsic" coherent state in the reduced phase space, in order to estimate the time for this state to spread significantly.

description: Grade is one of the key aspects of crop quality. In this article, I summarize basic issues and review some findings from empirical and theoretical research on grading. To begin with, I discuss how to measure quality by comparing three indices: individual attributes, grade, and price. Then I explain why grade is necessary. The underlying rationale is found in market failure caused by information asymmetry. Next, taking the impact of global warming on rice as an example, I demonstrate the importance of grade in farm economy. Empirical evidence indicates that higher temperature decreases farm revenue by deteriorating quality rather than quantity. Finally, I turn to the policy question of how to improve grade. Specifically, I focus on quality payment, which sets different subsidy rates by grades. Theoretical analysis shows that, under plausible assumptions, quality payment improves both grade and yield in a more cost effective manner than other types of payments such as quantity payments, area payments or decoupled payments.

description: To make an approach to this report theme, the imported food focused on is imported beef from Australia and America. Quality is defined as attributes for which the direction of good evaluation by all buyers is identical, and safety is included in quality. To resolve this issue, practices of improving beef quality and safety in the imported beef food system, from cattle production to its import are surveyed, with an explication of vertical relations among players and market structure for each stage in the food system. Finally, choices concerning imported beef quality and safety level are considered, analyzing some performances and their factors for improving imported beef quality and safety.

description: Spectral energy distributions (SEDs) are useful primary and complementary tools in the analysis of observations of young stars. However, the process of collating, inspecting, and flux-converting archival photometry and spectroscopy to build spectral energy distributions for young stars can be time-consuming. Here, I present SEDBYS (Spectral Energy Distribution Builder for Young Stars), a python-based repository of command-line tools built to (i) query online photometric and spectroscopic catalogs and a distributed database of archival photometry, (ii) use a look-up table of zero points to flux-convert the acquired data, (iii) enable visual inspection of the SED and (iv) handle book-keeping to collate references in bibTeX format. The code is distributed via git and is equipped with additional tools to enable users to add existing or forthcoming catalogs to the list of sources queried, ensuring the longevity of SEDBYS as a tool for the star formation community.

description: The majority of the youth in Ethiopia live in rural areas where agriculture is the main source of livelihood. Using gender- and age-specific values of agricultural labor return (shadow wages), we systematically analyse trends, patterns and prospects of youth’s labor supply in agriculture across space (farm locations). We also analyse whether the household male and female youth members’ agricultural labor supply is responsive to economic incentives. We investigate these using shadow wages estimation techniques applied to farm-household panel data collected during the 2010/11 and 2014/15 agricultural seasons. The results indicate that trends and patterns of the youth’s involvement in agriculture vary across gender and farm work locations, and so do their labor returns. Yet the on-farm participation for youth members is declining across time irrespective of gender, whilst their participation in off-farm activities is increasing. The findings also suggest that changes in agricultural shadow wages matter for the youth’s involvement in the sector, but their impact differs for male and female youth. The results are consistent after controlling for individual heterogeneity, sample selection and instrumenting for possible endogeneity. In addition, we find that youth’s intentions and actual engagement in agricultural production vary greatly. This suggests that the frequent narrative of youth disengaging from agriculture may be a result of methodological flaws or data limitations. Taking into account the intensity of the youth’s involvement in family farm, own farm and off-farm work, the results challenge the presumption that youth are abandoning agriculture, at least in agricultural potential areas of Ethiopia. Instead the youth’s involvement makes an important economic contribution to the operation of the family farm. Therefore, it is necessary to invest in agricultural development to enhance productivity and employment opportunities; and structural transformation that addresses the imperfections and rigidities in labor and other input markets to make agriculture more attractive to youth.

description: Quantum time crystals are systems characterised by spontaneously emerging periodic order in the time domain. A range of such phases has been reported. The concept has even been discussed in popular literature, and deservedly so: while the first speculation on a phase of broken time translation symmetry did not use the name "time crystal", it was later adopted from 1980's popular culture. For the physics community, however, the ultimate qualification of a new concept is its ability to provide predictions and insight. Confirming that time crystals manifest the basic dynamics of quantum mechanics is a necessary step in that direction. We study two adjacent quantum time crystals experimentally. The time crystals, realised by two magnon condensates in superfluid $^3$He-B, exchange magnons leading to opposite-phase oscillations in their populations -- AC Josephson effect -- while the defining periodic motion remains phase coherent throughout the experiment.

description: Open quantum many body systems describe a number of experimental platforms relevant for quantum simulations, ranging from arrays of superconducting circuits to ultracold atoms in optical lattices. Their theoretical understanding is hampered by their large Hilbert space and by their intrinsic nonequilibrium nature, limiting the applicability of many traditional approaches. In this work we extend the nonequilibrium bosonic Dynamical Mean Field Theory (DMFT) to Markovian open quantum systems. Within DMFT, a Lindblad master equation describing a lattice of dissipative bosonic particles is mapped onto an impurity problem describing a single site embedded in its Markovian environment and coupled to a self-consistent field and to a non-Markovian bath, where the latter accounts for finite lattice connectivity corrections beyond Gutzwiller mean-field theory. We develop a non-perturbative approach to solve this bosonic impurity problem, which treats the non-Markovian bath in a non-crossing approximation. As a first application, we address the steady-state of a driven-dissipative Bose-Hubbard model with two-body losses and incoherent pump. We show that DMFT captures hopping-induced dissipative processes, completely missed in Gutzwiller mean-field theory, which crucially determine the properties of the normal phase, including the redistribution of steady-state populations, the suppression of local gain and the emergence of a stationary quantum-Zeno regime. We argue that these processes compete with coherent hopping to determine the phase transition towards a non-equilibrium superfluid, leading to a strong renormalization of the phase boundary at finite-connectivity. We show that this transition occurs as a finite-frequency instability, leading to an oscillating-in-time order parameter, that we connect with a quantum many-body synchronization transition of an array of quantum van der Pol oscillators.

description: Quantum mechanics forbids deterministic discrimination among non-orthogonal states. Nonetheless, the capability to distinguish nonorthogonal states unambiguously is an important primitive in quantum information processing. In this work, we experimentally implement generalized measurements in an optical system and demonstrate the first optimal unambiguous discrimination between three nonorthogonal states, with a success rate of 55%, to be compared with the 25% maximum achievable using projective measurements. Furthermore we present the first realization of unambiguous discrimination between a pure state and a nonorthogonal mixed state.

description: We investigate the Brownian diffusion of particles in one spatial dimension and in the presence of finite regions within which particles can either evaporate or be reset to a given location. For open boundary conditions, we highlight the appearance of a Brownian yet non-Gaussian diffusion: at long times, the particle distribution is non-Gaussian but its variance grows linearly in time. Moreover, we show that the effective diffusion coefficient of the particles in such systems is bounded from below by $(1-2/π)$ times their bare diffusion coefficient. For periodic boundary conditions, i.e., for diffusion on a ring with resetting, we demonstrate a "gauge invariance" of the spatial particle distribution for different choices of the resetting probability currents, in both stationary and non-stationary regimes. Finally, we apply our findings to a stochastic biophysical model for the motion of RNA polymerases during transcriptional pauses, deriving analytically the distribution of the length of cleaved RNA transcripts and the efficiency of RNA cleavage in backtrack recovery.
