description: A prerequisite for isolating diseased cells requires a mechanism for effective mass-based separation. This objective, however, is generally rather challenging because typically no valid correlation exists between the size of the particles and their mass value. We consider an inertial Brownian particle moving in a symmetric periodic potential and subjected to an externally applied unbiased harmonic driving in combination with a constant applied bias. In doing so we identify a most efficient separation scheme which is based on the anomalous transport feature of negative mobility, meaning that the immersed particles move in the direction opposite to the acting bias. This work is first of its kind in demonstrating a tunable separation mechanism in which the particle mass targeted for isolation is effectively controlled over a regime of nearly two orders of mass-magnitude upon changing solely the frequency of the external harmonic driving. This approach may provide mass selectivity required in present and future separation of a diversity of nano and micro-sized particles of either biological or synthetic origin.

Superconductors in realistic geometries: Geometric edge barrier versus pinning

Subjects: subject: Superconductivity (cond-mat.supr-con)
subject: FOS: Physical sciences

description: The magnetic response of type-II superconductors can be irreversible due to two different reasons: vortex pinning and barriers for flux penetration. Even without bulk pinning and in absence of a microscopic Bean-Lingston surface barrier for vortex penetration, superconductors of nonellipsoidal shape can exhibit a large geometric barrier for flux penetration. This edge barrier and the resulting irreversible magnetization loops and flux-density profiles are computed from continuum electrodynamics for superconductor strips and disks with constant thickness, both without and with bulk pinning. Expressions for the field of first flux entry H_en and for the reversibility field H_rev above which the pin-free magnetization becomes reversible are given. Both fields are proportional to the lower critical field H_c1 and else depend only on the specimen shape. These realistic results are compared with the reversible magnetic behavior of ideal superconductor ellipsoids.

description: In this paper we use one-loop chiral perturbation theory in order to compare lattice computations of the K+ to pi+ pi0 decay amplitude with the experimental value. This makes it possible to investigate three systematic effects that plague lattice computations: quenching, finite-volume effects, and the fact that lattice computations have been done at unphysical values of the quark masses and pion external momenta (only this latter effect shows up at tree level). We apply our results to the most recent lattice computation, and find that all three effects are substantial. We conclude that one-loop corrections in chiral perturbation theory help in explaining the discrepancy between lattice results and the real-world value. We also revisit B_K, which is closely related to the K+ to pi+ pi0 decay amplitude by chiral symmetry.

description: Sustaining cooperation among unrelated individuals is a fundamental challenge in biology and the social sciences. In human society, this problem can be solved by establishing incentive institutions that reward cooperators and punish free-riders. Most of the previous studies have focused on which incentives promote cooperation best. However, a higher cooperation level does not always imply higher group fitness, and only incentives that lead to higher fitness can survive in social evolution. In this paper, we compare the efficiencies of three types of institutional incentives, namely, reward, punishment and a mixture of reward and punishment, by analysing the group fitness at the stable equilibria of evolutionary dynamics. We find that the optimal institutional incentive is sensitive to decision errors. When there is no error, a mixture of reward and punishment can lead to high levels of cooperation and fitness. However, for intermediate and large errors, reward performs best, and one should avoid punishment. The failure of punishment is caused by two reasons. First, punishment cannot maintain a high cooperation level. Second, punishing defectors almost always reduces the group fitness. Our findings highlight the role of reward in human cooperation. In an uncertain world, the institutional reward is not only effective but also efficient.

description: New measurements of the cosmic ray fluxes (p, e+, e- and Helium) performed by the Alpha Magnetic Spectrometer (AMS) during a ten days flight of space shuttle have revealed the existence of significant fluxes of particles below the geomagnetic cutoff. These fluxes exhibit a number of remarkable properties, such as a He-3/He-4 ratio of order ~10, an e+/e- ratio of order ~4 and production from well defined regions of the Earth that are distinct for positively and negatively charged particles. In this work we show that the natural hypothesis, that these subcutoff particles are generated as secondary products of primary cosmic ray interactions in the atmosphere can reproduce all the observed properties. We also discuss the implications of the subcutoff fluxes for the estimate of the atmospheric neutrino fluxes, and find that they represent a negligibly small correction. On the other hand the AMS results give important confirmations about the assumption of isotropy for the interplanetary cosmic ray fluxes also on large angular scales, and on the validity of the geomagnetic effects that are important elements for the prediction of the atmospheric neutrino fluxes.

description: Automatic motion compensation and adjustment of an intraoperative imaging modality's field of view is a common problem during interventions. Optical coherence tomography (OCT) is an imaging modality which is used in interventions due to its high spatial resolution of few micrometers and its temporal resolution of potentially several hundred volumes per second. However, performing motion compensation with OCT is problematic due to its small field of view which might lead to tracked objects being lost quickly. We propose a novel deep learning-based approach that directly learns input parameters of motors that move the scan area for motion compensation from optical coherence tomography volumes. We design a two-path 3D convolutional neural network (CNN) architecture that takes two volumes with an object to be tracked as its input and predicts the necessary motor input parameters to compensate the object's movement. In this way, we learn the calibration between object movement and system parameters for motion compensation with arbitrary objects. Thus, we avoid error-prone hand-eye calibration and handcrafted feature tracking from classical approaches. We achieve an average correlation coefficient of 0.998 between predicted and ground-truth motor parameters which leads to sub-voxel accuracy. Furthermore, we show that our deep learning model is real-time capable for use with the system's high volume acquisition frequency.

 Distribution and ecology. – Benstonea pilaris is endemic to the rainforests of Peninsular Malaysia (STONE, 1969).
 Observations. – The type collection (Ridley s.n.) has not been found in SING, but a steril duplicate has recently been rediscovered by HB at Kew, which is here designated as the lectotype. In 1978, STONE designated a specimen at KLU (Mahmud & Sharif s.n.) as the neotype, but the rediscovery of the type revokes this nomenclatural act. As Mahmud & Sharif s.n. is a fertile collection including a complete syncarp, and clearly belongs to B.pilaris, we designate it as the epitype.

description: Insight into the electroweak (EW) and Higgs sectors can be achieved through measurements of vector boson scattering (VBS) processes. The scattering of EW bosons are rare processes that are precisely predicted in the Standard Model (SM) and are closely related to the Higgs mechanism. Modifications to VBS processes are also predicted in models of physics beyond the SM (BSM), for example through changes to the Higgs boson couplings to gauge bosons and the resonant production of new particles. In this review, experimental results and theoretical developments of VBS at the Large Hadron Collider, its high luminosity upgrade, and future colliders are presented.

description: Current and its noise in a ferromagnetic double tunnel barrier device with a small spacer particle were studied in the framework of the sequential tunneling approach. Analytical formulae were derived for electron tunneling through the spacer particle containing only a single energy level. It was shown that Coulomb interactions of electrons with a different spin orientation lead to an increase of the tunnel magnetoresistance. Interactions can also be responsible for the negative differential resistance. A current noise study showed, which relaxation processes can enhance or reduce fluctuations leading either to a super-Poissonian or a sub-Poissonian shot noise.

description: Introduction: Subcutaneous nodules are a rare adverse event following immunization (AEFI). Reported cases have frequently been associated with aluminum-containing vaccines. Despite the development of a consensus definition of a subcutaneous nodule from the Brighton Collaboration in 2004, there continues to be variation in definitions used in published literature. Areas covered: We reviewed the literature regarding subcutaneous nodule etiology, definition, clinical features, management, and approach to future immunizations. Embase and MEDLINE databases were searched with relevant MeSH terms initially on 8 November 2016, the same searches were repeated on 9 September 2018 prior to finalizing this review. We reviewed published case reports and larger studies reporting subcutaneous nodules and also reviewed articles discussing broader use of aluminum in immunizations and AEFIs. Expert commentary: Consensus from clinicians regarding the approach to management of subcutaneous nodules is vital. We believe that the safety concerns regarding aluminum causing subcutaneous nodules are far outweighed by the benefits of vaccines containing aluminum. Ultimately, supporting subsequent immunizations in individuals that develop nodules needs to be a priority.

description: We analyze a minimal flavored gauge mediation model in which the electroweak Higgs and messenger doublets are embedded in multiplets of a discrete non-Abelian symmetry. In this scenario, the minimal Higgs-messenger sector that is consistent with the 125 GeV Higgs mass has two vectorlike pairs of messenger fields. This scenario is obtained in a specific limit of the superpotential interactions of the Higgs-messenger fields and the matter fields. Due to the structure of the messenger-matter Yukawa couplings in this limit, sizable stop mixing and flavor-diagonal soft supersymmetry breaking parameters are achieved. In most of the parameter space, the masses of the colored superpartners are at most in the 5-6 TeV range.

description: Recently, unusual and strikingly beautiful seahorse-like growth patterns have been observed under conditions of quasi-two-dimensional growth. These `S'-shaped patterns strongly break two-dimensional inversion symmetry; however such broken symmetry occurs only at the level of overall morphology, as the clusters are formed from achiral molecules with an achiral unit cell. Here we describe a mechanism which gives rise to chiral growth morphologies without invoking microscopic chirality. This mechanism involves trapped electrostatic charge on the growing cluster, and the enhancement of growth in regions of large electric field. We illustrate the mechanism with a tree growth model, with a continuum model for the motion of the one-dimensional boundary, and with microscopic Monte Carlo simulations. Our most dramatic results are found using the continuum model, which strongly exhibits spontaneous chiral symmetry breaking, and in particular finned `S' shapes like those seen in the experiments.

description: In the era of big data, analysts usually explore various statistical models or machine learning methods for observed data in order to facilitate scientific discoveries or gain predictive power. Whatever data and fitting procedures are employed, a crucial step is to select the most appropriate model or method from a set of candidates. Model selection is a key ingredient in data analysis for reliable and reproducible statistical inference or prediction, and thus central to scientific studies in fields such as ecology, economics, engineering, finance, political science, biology, and epidemiology. There has been a long history of model selection techniques that arise from researches in statistics, information theory, and signal processing. A considerable number of methods have been proposed, following different philosophies and exhibiting varying performances. The purpose of this article is to bring a comprehensive overview of them, in terms of their motivation, large sample performance, and applicability. We provide integrated and practically relevant discussions on theoretical properties of state-of- the-art model selection approaches. We also share our thoughts on some controversial views on the practice of model selection.

description: Using the (effective) classical approximation, we compute numerically time-dependent correlation functions in the SU(2)-Higgs model around the electroweak phase transition, for $m_H \approx m_W$. The parameters of the classical model have been determined previously by the dimensional reduction relations for time-independent correlators. The $H$ and $W$ correlation functions correspond to gauge invariant fields. They show damped oscillatory behavior from which we extract frequencies $\om$ and damping rates $\gm$. In the Higgs phase the damping rates have roughly the values obtained in analytic calculations in the quantum theory. In the plasma phase (where analytic estimates for gauge invariant fields are not available), the damping rate associated with $H$ is an order of magnitude larger than in the Higgs phase, while the $W$ correlator appears to be overdamped, with a small rate. The frequency $\om_H$ shows a clear dip at the transition. The results are approximately independent of the lattice spacing, but this appears to be compatible with the lattice spacing dependence expected from perturbation theory.
description: 27 pages, latex, 13 figures. Improved presentation, data unchanged. New is the conclusion that the apparent lattice spacing independence of the `plasmon' frequency is compatible with the divergencies expected from perturbation theory. (Version resubmitted to NPB on 17 July 1997.)

description: In this work we compute for the first time the so-called Complete-NLO predictions for top-quark pair hadroproduction in association with at least one isolated photon ($ t \bar t \gamma$). We also compute NLO QCD+EW predictions for the similar case with at least two isolated photons ($ t \bar t \gamma\gamma$) and for single-top hadroproduction in association with at least one isolated photon. In addition, we complement our results with NLO QCD+EW predictions of the hadronic and leptonic decays of top-quark including an isolated photon. All these results have been obtained in a completely automated approach, by extending the capabilities of the MadGraph5_aMC@NLO framework and enabling the Complete-NLO predictions for processes with isolated photons in the final state. We discuss the technical details of the implementation, which involves a mixed EW renormalisation scheme for such processes.

description: We show the existence of new stable ring-like localized scalar field configurations whose stability is due to a combination of topological and nontopological charges. In that sense these defects may be called semitopological. These rings are Noether charged and also carry Noether current (they are superconducting). They are local minima of the energy in scalar field theories with an unbroken U(1) global symmetry. We obtain numerical solutions of the field configuration corresponding to large rings and derive virial theorems demonstrating their stability. We also derive the minimum energy field configurations in 3D and simulate the evolution of a finite size Q ring on a three dimensional lattice thus generalizing our demonstration of stability.

 Typus: SOLOMON ISLANDS. SantaIsabel Isl.: Totolu islet, X.1957, Stone 2468 (holo-: BISH!; iso-: K [K000781510, K000781511]!).
 Distribution and ecology. – Benstonea poronavila is confined to the Solomon Islands (in Santa Ysabel and Guadalcanal).
 Observations. – The habit of Benstonea poronavila is very similar to that of B. setistyla (Warb.) Callm. & Buerki, which occurs in Papua New Guinea, a poorly-known species represented by only a few collections from lowland forests in Sepik and Morobe Prov. (JEBB, 1992). The very long styles seem to be distinctive to B. setistyla (JEBB, 1992: 24), and we therefore maintain these two species separate. Further fieldwork will be needed to clarify whether they are indeed distinct.

description: This paper presents a fractional generalized Cauchy process (FGCP) with an additive and a multiplicative Gaussian white noise for describing subordinated anomalous fluctuations. The FGCP displays intermittent dynamics during random time durations, whose analytical representation is given by the It$\hat{\rm o}$ stochastic integral. The associated probability density function is given by the Tsallis $q$-Gaussian distribution at the stationary state. The method of fractional Feynman-Kac formula shows that weak ergodicity breaking of the FGCP depends on the existence of the subordinator and/or the divergence of variance.

 ≡ Pandanus parvus Ridl. in J. Straits Branch Roy. Asiat. Soc. 33: 171. 1900.
 Typus: SINGAPORE. PulauUbin: Kranji, 1892, Ridley 8928 (lecto-: SING [SING0059862]!) (designated by ST. JOHN, 1963: 337).
 Distribution and ecology. – Benstonea parva grows in lowland to montane rainforests (from sea level to 1500 m) and is distributed from Peninsular Malaysia through Singapore to Borneo (Sabah).
 Observations. – This small terrestrial herbaceous species is characterized by its short monocaulous habit (up to 60 cm high), its broad but small leaves that are abruptly caudateacuminate in the distal part, glaucous on the abaxial surface, and its rather small globose terminal syncarp (Fig. 5A). It remains difficult to differentiate B.parva from B.unguiculata (Ridl.) Callm. & Buerki (with slightly narrower leaves and larger fruit), and further collections are needed to confirm whether they are distinct.

The flavour number dependence of our result enlightens the mechanism of quark loop cancellation in the quenched effective theory for any Green function or S matrix element. We also apply our results to $ππ$ scattering and evaluate the coefficient of the chiral log in the S-wave scattering lengths for the quenched case.

The Force-Velocity Relation for Growing Biopolymers

description: The process of force generation by the growth of biopolymers is simulated via a Langevin-dynamics approach. The interaction forces are taken to have simple forms that favor the growth of straight fibers from solution. The force-velocity relation is obtained from the simulations for two versions of the monomer-monomer force field. It is found that the growth rate drops off more rapidly with applied force than expected from the simplest theories based on thermal motion of the obstacle. The discrepancies amount to a factor of three or more when the applied force exceeds 2.5kT/a, where a is the step size for the polymer growth. These results are explained on the basis of restricted diffusion of monomers near the fiber tip. It is also found that the mobility of the obstacle has little effect on the growth rate, over a broad range.

 Distribution and ecology. – Benstonea rupestris is endemic to the lowland rainforests of Sabah and Sarawak (Borneo).
 Observations. – STONE (1978) described Pandanus scandens based on a more mature infructescence than that of P. rupestris, which was described six years earlier. He distinguished these two taxa based on the number of syncarps (5 in P.scandens vs 7 to 9 in P. rupestris) and other minor morphological characters such as the leaf length (c. 3 Χ 105 cm vs 3-4 190 cm) and color (glaucous vs not glaucous beneath). Recent observations in the field by MWC and SB have, however, confirmed that populations corresponding to Benstonea rupestris are characterized by along pendent infructescence with up to 9 oblong syncarps (sometimes 5 to 8) and that leaf length and width fall within the normal variation of B.rupestris as currently circumscribed (Fig. 5C).
 Pandanus oresbios, also described in 1978, is here considered as a synonym of Benstonea rupestris. It was described based on an immature infructescence, and despite its apparent narrower leaves (2 cm vs 3-4 cm in B. rupestris) and smaller syncarps (c. 3.5 cm in length vs 8 cm), it appears to represent the same entity as B.rupestris. Further field observations are needed to understand the relationship between B.rupestris and B.calcinacta, another species that may also be part of this group but is provisionally accepted here (see above).

description: We present the basic aspects of deep inelastic phenomena in the framework of the QCD parton model. After recalling briefly the standard kinematics, we discuss the physical interpretation of unpolarized and polarized structure functions in terms of parton distributions together with several important sum rules. We also make a rapid survey of the experimental situation together with phenomenological tests, in particular concerning various QCD predictions. In the summary, we try to identify some significant open questions, to clarify where we stand and to see what we expect to learn in the future.

description: Phase diagrams of the one-dimensional extended Hubbard model with a nearest neighbor interaction $V$ and site-off-diagonal (bond-charge $X$ and bond-bond $W$) interactions at half-filling are obtained numerically, using the level-crossing approach for finite-size clusters. This analysis is straightforward extension of the preceding work [cond-mat/9909277], where only the $X$ term is considered as a site-off-diagonal term. Similarly to the $X$ term, the $W$ term enlarges bond-charge-density-wave (BCDW) and bond-spin-density-wave (BSDW) phases for $W<0$ and $W>0$ cases, respectively. In the strong-coupling region, however, the $W$ term causes ferromagnetism for $W>0$, and shifts the boundary of the phase separation in the $U/t\ll-1$ region, which are different from the roles of the $X$ term. In addition, we discuss a parameter region where the BSDW state is the exact ground state, and show that the exactly solvable point appears just on the phase boundary between the BSDW and the ferromagnetic phases.

Combining neural and knowledge-based approaches to Named Entity Recognition in Polish

Subjects: subject: Computation and Language (cs.CL)

description: Named entity recognition (NER) is one of the tasks in natural language processing that can greatly benefit from the use of external knowledge sources. We propose a named entity recognition framework composed of knowledge-based feature extractors and a deep learning model including contextual word embeddings, long short-term memory (LSTM) layers and conditional random fields (CRF) inference layer. We use an entity linking module to integrate our system with Wikipedia. The combination of effective neural architecture and external resources allows us to obtain state-of-the-art results on recognition of Polish proper names. We evaluate our model on data from PolEval 2018 NER challenge on which it outperforms other methods, reducing the error rate by 22.4% compared to the winning solution. Our work shows that combining neural NER model and entity linking model with a knowledge base is more effective in recognizing named entities than using NER model alone.

description: We consider $e e q q$ contact interactions as a possible origin of an excess of events above Standard Model predictions in $e^+ p \to e^+ jet$ at high $Q^2$ observed by the H1 and ZEUS collaborations at HERA. The HERA data prefer chirality RL or LR contact terms and atomic physics parity violation measurements severely limit parity-odd contact terms. With equal left-right and right-left chirality interactions at an effective scale of order 3 TeV we are able to reproduce the main features of the HERA data and still be consistent with Drell-Yan pair production at the Tevatron and hadron production at LEP 2 and TRISTAN.
