description: The thermal evolution of the spectral densities derivable from the two-point functions of the elementary and the quadratic composite fields of the O(N) model is studied in the isosinglet channel and in the broken symmetry phase at infinite N. The results are applied with realistic parameter values to the N=4 case. They provide a reasonable description of the $σ$ meson at T=0. Threshold enhancement is observed around $T\sim 1.07m_π$. For higher temperatures the maximum of the spectral function in the single meson channel decreases and becomes increasingly rounded.

Coupling of the magnetic and structural subsystems results in unusual magnetic features of the alloy. These uncommon magnetic properties of Ni2.18Mn0.82Ga are attributed to the first-order structural transition from a tetragonal ferromagnetic to a cubic paramagnetic phase.

description: This study measures the degree of oligopoly power of domestic marketers in the Korean white fluid milk market using natural experiments. It extends the number of experiments to eight times covering more than 20 years and considers a dynamic game to check the robustness of the estimates covered by previous studies. The results show that the estimates obtained by the eight experiments and a dynamic game are quite similar to those obtained by a one-shot experiment with a static game. The results show that the Korean white fluid milk market is far from perfect competition.

description: Consider the set $\mathcal{S}=\lbraceρ_{SE}\rbrace$ of possible initial states of the system-environment, steered from a tripartite reference state $ω_{RSE}$. Buscemi [F. Buscemi, Phys. Rev. Lett. 113, 140502 (2014)] showed that the reduced dynamics of the system, for each $ρ_{S}\in \mathrm{Tr}_{E}\mathcal{S}$, is always completely positive if and only if $ω_{RSE}$ is a Markov state. There, during the proof, it has been assumed that the dimensions of the system and the environment can vary through the evolution. Here, we show that this assumption is necessary: we give an example for which, though $ω_{RSE}$ is not a Markov state, the reduced dynamics of the system is completely positive, for any evolution of the system-environment during which the dimensions of the system and the environment remain unchanged. As our next result, we show that the result of Muller-Hermes and Reeb [A. Muller-Hermes and D. Reeb, Ann. Henri Poincare 18, 1777 (2017)], of monotonicity of the quantum relative entropy under positive maps, cannot be generalized to the Hermitian maps, even within their physical domains.

description: The farm produce logistics plays an important role in promoting the agricultural production and prosperity of the rural economy, so grasping the main factors influencing the development of farm produce logistics, is of important significance to accelerating the development of farm produce logistics. The values of identification coefficient in the grey relational analysis are taken based on the experience, so the accuracy of the results is affected. This article uses the improved fuzzy grey relational analysis to analyze the main factors influencing farm produce logistics. The results show that the number of storage companies has a great impact on the development of farm produce logistics, followed by the farm produce processing machinery capacity, rural transport infrastructure, farm produce market conditions and government financial support for agriculture, while the total number of Internet users in rural areas has an limited impact on the development of farm produce logistics.

description: Quantifying lumbar back motion during functional activities in real-life environments may contribute to a better understanding of common pathologies such as spinal disorders. The current study therefore aimed at the comparative evaluation of the Epionics SPINE system, a portable device for measuring sagittal lumbar back motion during functional activities. Twenty healthy participants were therefore evaluated with the Epionics SPINE and a Vicon motion capture system in two identical separate research visits. They performed the following activities: standing, sitting, chair rising, box lifting, walking, running and a counter movement jump (CMJ). Lumbar lordosis angles were extracted as continuous values as well as average and range of motion (ROM) parameters. Agreement between the systems was evaluated using Bland-Altman analyses, whereas within- and between-session reliability were assessed using intraclass correlation coefficients (ICC) and minimal detectable changes (MDC). The analysis showed excellent agreement between the systems for chair rising, box lifting and CMJ with a systematic underestimation of lumbar lordosis angles during walking and running. Reliability was moderate to high for all continuous and discrete parameters (ICC>=0.62), except for ROM during running (ICC=0.29). MDC values were generally below 15°, except for CMJ (peak values up to 20° within and 25° between the sessions). The Epionics SPINE system performed similarly to a Vicon motion capture system for measuring lumbar lordosis angles during functional activities and showed high consistency within and between measurement sessions. These findings can serve researchers and clinicians as a bench mark for future investigations using the system in populations with spinal pathologies.

description: There are problems of inadequate natural endowment and weak stamina in the development of micro-credit loans to farmers in China. Specifically, existing problems include narrow profit space, serious non-agricultural trend of funds, high dependence on government support, short life cycle, and constantly increasing operating risks. These problems are related to endogenous drawback in design, defect in operating procedure, lagging in relevant policies and measures, and vacancy in risk compensation mechanism.
A combined analysis technique for the search for fast magnetic monopoles with the MACRO detector

Subjects: subject: High Energy Physics - Experiment (hep-ex)
subject: FOS: Physical sciences

description: We describe a search method for fast moving ($β> 5 \times 10^{-3}$) magnetic monopoles using simultaneously the scintillator, streamer tube and track-etch subdetectors of the MACRO apparatus. The first two subdetectors are used primarily for the identification of candidates while the track-etch one is used as the final tool for their rejection or confirmation. Using this technique, a first sample of more than two years of data has been analyzed without any evidence of a magnetic monopole. We set a 90% CL upper limit to the local monopole flux of $1.5 \times 10^{-15} cm^{-2} s^{-1} sr^{-1}$ in the velocity range $5 \times 10^{-3} \le β\le 0.99$ and for nucleon decay catalysis cross section smaller than $\sim 1 mb$.

description: Environmental issues span many traditional disciplinary boundaries and require data from across the environmental sciences, including physical sciences like oceanography and hydrology, life sciences including ecology, biodiversity, and environmental genomics, and social sciences like anthropology and economics. Issues surrounding reproducibility and transparency have grown in importance across these allied disciplines. While there have been longstanding efforts to document data structures, methods, and modeling and analysis, there is increasing need to also record the provenance of scientific processes to improve computational reproducibility in the environmental sciences. We describe efforts in the DataONE network of repositories (https://dataone.org) to adopt a shared provenance framework based on the ProvONE provenance model, which extends PROV-O with specific concepts to document scientific workflows. And we discuss the emerging approaches in the Whole Tale (https://wholetale.org) project to create effective tooling to enable provenance capture in the tools that researchers frequently use.

description: Classifying limb movements using brain activity is an important task in Brain-computer Interfaces (BCI) that has been successfully used in multiple application domains, ranging from human-computer interaction to medical and biomedical applications. This paper proposes a novel solution for classification of left/right hand movement by exploiting a Long Short-Term Memory (LSTM) network with attention mechanism to learn the electroencephalogram (EEG) time-series information. To this end, a wide range of time and frequency domain features are extracted from the EEG signals and used to train an LSTM network to perform the classification task. We conduct extensive experiments with the EEG Movement dataset and show that our proposed solution our method achieves improvements over several benchmarks and state-of-the-art methods in both intra-subject and cross-subject validation schemes. Moreover, we utilize the proposed framework to analyze the information as received by the sensors and monitor the activated regions of the brain by tracking EEG topography throughout the experiments.

description: This study relies on the Ricardian method to estimate the damages of climate change to US agriculture. The study uses repeated cross sectional analyses of US Census data collected at the county level from 1978-2002. Regressions of farmland value on climate and other control variables reveal that climate consistently affects farmland values across the US. The 1978 and 1982 data imply that warming is beneficial to farming whereas the data from more recent years implies warming is harmful. Linear, enhanced linear and log linear regressions all confirm these results. With the linear and enhanced linear models, projections of future impacts from climate models lead to similar findings. With the Hadley and uniform climate scenarios, coefficients from the 1978 and 1982 data generally imply benefits whereas the coefficients from the later data imply damages. The loglinear model leads to different results. The loglinear model implies that these climate scenarios will generally be beneficial, although the benefits do vary across years. All the regression models suggest the mild PCM scenarios will generally be beneficial. The climate results are mixed. They generally imply that mild warming is beneficial but more extensive warming is harmful to the US. However, the results are not stable across time, suggesting the repeated cross sections are still not capturing all the important factors that change annually in the farmland market.

description: The BFSS matrix model provides an example of gauge-theory / gravity duality where the gauge theory is a model of ordinary quantum mechanics with no spatial subsystems. If there exists a general connection between areas and entropies in this model similar to the Ryu-Takayanagi formula, the entropies must be more general than the usual subsystem entanglement entropies. In this note, we first investigate the extremal surfaces in the geometries dual to the BFSS model at zero and finite temperature. We describe a method to associate regulated areas to these surfaces and calculate the areas explicitly for a family of surfaces preserving $SO(8)$ symmetry, both at zero and finite temperature. We then discuss possible entropic quantities in the matrix model that could be dual to these regulated areas.

The parton distributions, value of strong coupling constant, and high-twist terms are extracted and their stability with respect to account of the NNLO corrections is analyzed. All the quantities are generally stable within their experimental errors. Obtained value of the strong coupling constant is $α_s^{\rm NNLO}(M_{\rm Z})=0.1143\pm 0.0014 ({\rm exp})$ with a guess $α_s^{\rm NNNLO}(M_{\rm Z})\sim 0.113$.

Egle anderssoni

description: 6. Egle anderssoni sp. nov.
Figs. 30, 69–74, 80, 81.
 Etymology. Named after Hugo Andersson (Lund, Sweden), former dipterist at the Museum of Zoology, Lund University, who first collected the species at Klagshamn in Skåne.
 Description. Closely resembling Egle ciliata in size and general habitus, but different in both sexes as follows: Fronto-parafacial angle more strongly developed, lying practically in line with projected lower facial margin, resulting in a “buccate” head (Fig. 30). Parafacial very broad on upper part, ca. 1.4 times width of postpedicel. Interantennal facial ridge less developed, shallow. Haustellum and palp distinctly shorter. Proepisternals 3–5. Lower calypter shorter than upper calypter. Fore tibia with 0–1 pd-seta. Male. Frons on upper part broader than diameter of anterior ocellus and with broader, narrowly separated parafrontals. Gena even broader and setae more abundant. Terminalia (Figs. 69–74): Very similar to those of E. brevicornis, but apical extension of cerci and in particular surstyli proportionately shorter. Female. Oviscapt (Figs. 80, 81): Hind marginal setulae on tergite VIII uni-serial; pair of fine setae present on hind part of sternite VIII pieces; cerci in broadest aspect widening posteriorly, broadly rounded on apical part.
 Material examined. Type material: SWEDEN [MZUL, ZMUC]: Skåne: Klagshamnsudde, on Salix, 1 male 15.iv.1982, 3 males (including holotype in MZUL), 3 females 18.iv.1982 (H. Andersson). MOROCCO [ZMUC]: Tizi-n’-Talrhemt pass, 1900m, 1 female 15.iv.1989 (Zool. Mus. Copenh. Exp.). SPAIN [ZMUC]: Alicante: Nat. Park Font Roja, 1 female 16.iii.2007 (V. Michelsen); Beniaia, stream bed, 2 males 18.iii.2007 (V. Michelsen).
 Biology. An early-season species found on flowering Salix spp. Larval development certainly takes place in the female catkins.
 Distribution. Hugo Andersson’s find in 1982 of this new, large-sized species of Egle near to the coast in southern Skåne (Sweden) was rather unexpected. I visited the type locality several times in April–May 2008 but did not find more specimens. The other known localities for E. anderssoni are in Spain and Morocco, which suggests that its main distribution lies in the western Mediterranean basin. It has surely been overlooked because of its early flight period and mainly southern distribution in Europe.
 Relationships. The shape of the male cerci and surstyli suggests a closest relationship with Egle brevicornis and the Nearctic counterpart E. washburni.

description: If the electron neutrino has an effective nonzero Majorana mass, then neutrinoless double beta decay will occur. However, the latter is possible also with a negligible neutrino mass. We show how this may happen in a simple model of scalar diquarks and dileptons. This possibility allows neutrino masses to be small and hierarchical, without conflicting with the possible experimental evidence of neutrinoless double beta decay.

description: There is a counter-intuitive expectation proposed by Huse {\it et al} [Phys. Rev. B {\bf 88}, 014206 (2013)], and Chandran {\it et al} [Phys. Rev. B 89,144201 (2014)]: Localization protects quantum order of groundstate even in high excited eigenstates. In this work, we numerically investigate the localization protection for symmetry-protected-topological (SPT) order by considering a modified XXZ spin model, related to an interacting Su-Schrieffer-Heeger (SSH) model. We systematically study how Many-body-localization (MBL) protects SPT for different disorder types and different forms of interactions. A certain disorder leads the clear degeneracy of the low-lying entanglement spectrum of each excited many-body eigenstates. This fact indicates that existence of edge modes, which is a hallmark of the SPT order, is protected by the MBL in excited many-body eigenstates. In addition, we also report how the MBL protected edge modes in excited many-body eigenstates fade away for a diagonal type disorder.

Egle inermoides

description: 13. Egle inermoides sp. nov.
Figs. 121–125, 185, 186.
 Etymology. The specific epithet ‘inermoides’ is derived from inermis, existing epithet for a closely related, Holarctic species, and ‘-oides’, a Greek adjectival suffix meaning resembling.
 Description. Very close to Egle inermis but different as follows: Even smaller, wing length 2.2–2.9mm.
 Male. Subgena shiny black, without dusting except narrowly towards subcranial cavity. Parafacial broader, in middle as wide as postpedicel. Fronto-parafacial angle more prominent, extended as far forward as lower facial margin. Submedian tibial setae even fewer: Fore- and mid tibiae even without ad-setae. Terminalia (Figs. 121–125): Sternite V with setal tufts postero-laterally on basal plate less dense, consisting of fewer setae and setulae; surstyli in posterior view without a transverse ridge distal to middle; apical extension of cerci thicker; also gonites and phallus show some differences.
 Female. Prementum shiny black, only with sporadic dusting. Subgena shiny black, without dusting except narrowly towards subcranial cavity. Parafacial in middle as wide as postpedicel. Fronto-parafacial angle more prominent, reaching as far forward as lower facial margin. Oviscapt (Figs. 185, 186): Sternite VII less broad and less sclerotized on posterior two-thirds.
 Material examined. Type material [ZMUC]: SPAIN: Alicante: Nat. Park Font Roja, 5 males (including holotype), 2 females 16.iii.2007 (V. Michelsen); Beniaia, stream bed, 7 males, 2 females 18.iii.2007 (V. Michelsen).
 Biology. Collected in early spring on flowering Salix growing in stream beds. Males were also seen swarming.
 Distribution. Only known from two localities in the Alicante province of Spain, but it has expectedly a wider distribution in southern Europe. Egle inermis and E. inermoides may credibly be considered as sisterspecies with vicariant distributions. However, Griffiths (2003) pointed to an equally credible sister-species relation between E. inermis and E. bicaudata in North America. These species appear equally close morphologically and also have vicariant distributions.
 Relationships. If both species-pairs E. inermis + E. inermoides and E. inermis + E. bicaudata are real and resulting from recent speciation events, it follows that E. inermis in a cladistic context is paraphyletic!

description: We discuss, how to study $I = 0$ quarkonium resonances decaying into pairs of heavy-light mesons using static potentials from lattice QCD. These static potentials can be obtained from a set of correlation functions containing both static and light quarks. As a proof of concept we focus on bottomonium with relative orbital angular momentum $L = 0$ of the $\bar{b} b$ pair corresponding to $J^{P C} = 0^{- +}$ and $J^{P C} = 1^{- -}$. We use static potentials from an existing lattice QCD string breaking study and compute phase shifts and $\mbox{T}$ matrix poles for the lightest heavy-light meson-meson decay channel. We discuss our results in the context of corresponding experimental results, in particular for $Υ(10860)$ and $Υ(11020)$.

description: We investigate a specific set of two-loop self-energy corrections involving squared decay rates and point out that their interpretation is highly problematic. The corrections cannot be interpreted as radiative energy shifts in the usual sense. Some of the problematic corrections find a natural interpretation as radiative nonresonant corrections to the natural line shape. They cannot uniquely be associated with one and only one atomic level. While the problematic corrections are rather tiny when expressed in units of frequency (a few Hertz for hydrogenic P levels) and do not affect the reliability of quantum electrodynamics at the current level of experimental accuracy, they may be of importance for future experiments. The problems are connected with the limitations of the so-called asymptotic-state approximation which means that atomic in- and out-states in the S-matrix are assumed to have an infinite lifetime.

description: This study investigates the Cup of Excellence coffee auctions and explains with behavioral economics observed intransitives in choice sets. Buyers are selecting lower quality coffees and paying higher prices for these coffees because they receive a higher rank. The estimates suggest that the representativeness and the framing heuristics explain the price premium for higher ranked coffees.

New scalar resonances from sneutrino-Higgs mixing in supersymmetry with small lepton number (R-parity) violation

description: We consider new s-channel scalar exchanges in top quark and massive gauge-bosons pair production in e+e- collisions, in supersymmetry with a small lepton number violation. We show that a soft bilinear lepton number violating term in the scalar potential which mixes the Higgs and the slepton fields can give rise to a significant scalar resonance enhancement in e+e- -> ZZ, W+W- and in e+e- -> t t(bar). The sneutrino-Higgs mixed state couples to the incoming light leptons through its sneutrino component and to either the top quark or the massive gauge bosons through its Higgs component. Such a scalar resonance in these specific production channels cannot result from trilinear Yukawa-like R-parity violation alone, and may, therefore, stand as strong evidence for the existence of R-parity violating bilinears in the supersymmetric scalar potential. We use the LEP2 measurements of the WW and ZZ cross-sections to place useful constrains on this scenario, and investigate the expectations for the sensitivity of a future linear collider to these signals. We find that signals of these scalar resonances, in particular in top-pair production, are well within the reach of linear colliders in the small lepton number violation scenario.

description: We study the impact of recent LHC $t$-channel single top-quark and top-antiquark measurements at centre-of-mass energies of 7, 8 and 13 TeV on the parton distribution functions (PDFs) of the proton. We consider, namely, total cross sections, top-antitop cross section ratios, and differential distributions. We present a critical appraisal of the data, studying in particular how their description is affected by the theoretical details that enter the computation of the corresponding observables: QCD and electroweak higher-order corrections, the flavour scheme, and the value of the bottom-quark threshold. We perform a series of fits to the data within the NNPDF3.1 framework, whereby next-to-next-to-leading order QCD corrections are applied to single top measurements in a systematic way. We find that there exists an optimal combination of data that maximises consistency with the rest of the dataset, and efficiency in constraining the up, down and, partially, gluon PDFs.

description: A rapid appraisal study carried out by ICIMOD and ILRI in collaboration with National Partner Institutions (NPIs) in four regions in the Hindu Kush Himalaya has demonstrated the fact that promotion of market oriented smallholder dairy farming in the hills/mountains can contribute positively to improving the livelihoods of small and marginal farmers, while conserving the fragile ecosystem. In the region, smallholder dairy farming is not a specialized enterprise, rather it is an integral part of mixed crops-livestock farming systems where a farm household owns one to two dairy animals along with other large and small animals on a small land holding ranging from 0.25 hectare to 1.00 hectare. Use of improved dairy animals and improved feed technologies have enabled smallholders to increase income and employment and improve family welfare including those of women and children. Based on the successful experience in some pocket areas it should be possible to replicate such model and experience in other degraded uplands of the hills/mountains for improving the livelihoods of small and poor farmers.
Smoothed mapping scheme for the VOF-DEM method in multiphase flow simulation

description: The unresolved CFD-DEM approach is developed to simulate the mixed flow of fluid and particles, which is very common in both industry and nature. As an extension, if the VOF model is implemented, multiple fluid phases would be enabled for CFD domain. To achieve that, the main challenge lies in the discontinuity of field mapping from the DEM domain to the CFD domain. Due the discontinuity, the minimum cell size of CFD is limited by the particle size, and the numerical stability is also affected greatly. To overcome the above issues, the kernel function is introduced to resolve the scalar variables of a particle into continued fields. Thus, the mapped terms due to coupling in CFD domain would be smoothed which improves the stability significantly. All the cells in the smoothing length of a particle would be considered in variable exchanging, so the limit on cell size is also released. Besides, this method doesn’t care about the type of mesh, the size variation over the whole CFD domain, and the particle gradation, which means it’s a versatile method. This smoothed VOF-DEM method is validated by the 2 cases.

description: Recent ferromagnetic resonance experiments and theory of Pt/Nb/Ni8Fe2 proximity-coupled structures strongly suggest that spin-orbit coupling (SOC) in Pt in conjunction with a magnetic exchange field in Ni8Fe2 are the essential ingredients to generate a pure spin supercurrent channel in Nb. Here, by substituting Pt for a perpendicularly magnetized Pt/Co/Pt spin-sink, we are able to demonstrate the role of SOC, and show that pure spin supercurrent pumping efficiency across Nb is tunable by controlling the magnetization direction of Co. By inserting a Cu spacer with weak SOC between Nb and Pt/(Co/Pt) spin-sink, we also prove that Rashba type SOC is key for forming and transmitting pure spin supercurrents across Nb. Finally, by engineering these properties within a single multilayer structure, we demonstrate a prototype superconducting spin-wave (SW) device in which lateral SW propagation is gateable via the opening or closing of a vertical pure spin supercurrent channel in Nb.

description: Within the framework of Weyl calculus we establish a quantum-classical correspondence for the time evolution of observables generated by a Dirac-Hamiltonian. This includes a semiclassical separation of particles and antiparticles. We then prove quantum ergodicity for Dirac-Hamiltonians under the condition that a skew product of the classical relativistic translational motion and relativistic spin precession is ergodic.

description: Producing an acceptable thermal relic abundance of dark matter with masses $\gg 10^2$ TeV is a challenge. We propose a novel mechanism where GeV-scale states establish a tiny thermal relic abundance for dark matter, which is later promoted to ultra massive status by a very light scalar. We refer to this dark matter as a THermal Ultra Massive Particle (THUMP). Direct detection of THUMPs can be naturally expected due to large scattering cross sections mediated by low mass states that couple THUMPs to the Standard Model. Our model generically leads to signals for the associated GeV-scale states at accelerator experiments.

Substructure of jets at HERA

description: The substructure of jets produced in an exclusive and a charm-induced dijet sample in photoproduction and in charged and neutral current interactions has been studied with the ZEUS detector at HERA. Jets were identified using the longitudinally invariant k_T cluster algorithm in the laboratory frame. The substructure of jets has been studied in terms of the jet shape and subjet multiplicity. Comparisons between the dijet sample and the quark-induced samples allow an extraction of the jet substructure for gluons. Leading-logarithm parton-shower Monte Carlo calculations give a good description of the differences between quark- and gluon-initiated jets. In neutral current interactions, the measurements have been compared to next-to-leading-order QCD calculations which are used to make a determination of the strong coupling constant, alpha_s.

description: Recent progress has witnessed that various topological physics can be simulated by electric circuits under alternating current. However, it is still a nontrivial problem if it is possible to simulate the dynamics subject to the Schrödinger equation based on electric circuits. In this work, we reformulate the Kirchhoff law in one dimension in the form of the Schrödinger equation. As a typical example, we investigate quantum walks in $LC$ circuits. We also investigate how quantum walks are different in topological and trivial phases by simulating the Su-Schrieffer-Heeger model in electric circuits. We then generalize them to include dissipation and nonreciprocity by introducing resistors, which produce non-Hermitian effects. We point out that the time evolution of one-dimensional quantum walks is exactly solvable with the use of the generating function made of the Bessel functions.
