description: Subfamily Syntexinae Benson, 1935   Remarks: The family Anxyelidae is included in the Siricoidea [= Anaxyelidae + “ Gigasiricidae ” + Siricidae (sensu Grimaldi & Engel 2005); = Anaxyelidae + Protosiricidae + Daohugoidae + Siricidae + Xiphydriidae (sensu Rasnitsyn & Zhang 2004a, b, Rasnitsyn 2006)] and comprises four subfamilies: the Late Jurassic Anaxyelinae Martynov, 1925, the Late Jurassic or Lower Cretaceous Kempendajinae Rasnitsyn, 1980, the Lower Cretaceous Dolichostigmatinae, Rasnitsyn 1968 and the Lower Cretaceous – Recent Syntexinae Benson, 1935. The palaeogeographical range of the family is extensive, specimens being known from Central Asia, England, Spain and Brazil. The Syntexinae includes three genera: the extant Syntexis Rohwer, 1915 and two Lower Cretaceous genera, Eosyntexis Rasnitsyn, 1990 (Neocomian of East Siberia, Berriasian of England and Barremian of Spain) and Cretosyntexis Rasnitsyn & Martínez-Delclòs, 2000 (Barremian of Spain) (see Fig. 5).
 New diagnosis of Syntexinae. Pedicel as long as scape (known only for Syntexis and Eosyntexis parva n. sp.) (Figs. 2G and 4B). Pronotum with dorsal face well developed and crossed by medial suture or impressed line (Fig. 2C). Mesonotum with distinct transverse rugae (known for Syntexis and Cretosyntexis, although in E. parva similar rugae are present on the pronotum) (Figs. 2A, C and 3E). Fore wing with SC completely lost, 1r-rs either longer than 2r-rs or lost. Hind wing with r-m placed near RS bending and with m-cu lost (known only for Syntexis and Eosyntexis senilis).
 Remarks. The Syntexinae show an important simplification and reduction of the wing venation (Fig. 1): fore wing with SC completely lost, RS more or less straightened between cells 1mcu and 2r due to 1r-rs crossvein either long or lost, distal R and RS sometimes lost; hind wing when known with distal venation somewhat reduced, with r-m crossvein displaced basally and m-cu lost. Also the long pedicel, furrowed pronotum and mesonotum with marked sculpture distinguish Syntexinae from the three other subfamilies.

Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: A prime number based parametrization for total neutrino-nucleon cross section is presented. The method employs the relation between prime numbers and their indices to reproduce neutrino cross sections for neutrino energies from the $MeV$ to the $PeV$ regions where experimental data are available. This prime-index relation provides estimates of the neutrino-nucleon cross sections valid across many decades of neutrino energy scales. The $PeV$ data are from the recently published astrophysical $ν_μ+ \bar ν_μ$ rates in the IceCube detector as well as neutrino-nucleon cross section measurements. A similar method has been employed for high energy $pp$ cross sections which explains the $(\ln s)^{2}$ parametrization first proposed by Heisenberg.

description: We empirically address the implications of biofuel policy regarding major grains, to the subsequent evolution of the markets for calories from the three major grains, maize, wheat and rice. The implied market variables, namely, market price, consumption, and stocks, using a structurally estimated model combined with data on current and projected demand shifts, replicate the levels and dynamics of actual market behaviors, including the price rise before and during the 2007-2008 world food price crisis and the price dip at the breakout of the latest financial crisis. Counterfactual market variables constructed by removing mandates and their effects on production suggest that the biofuel mandate is the main driving force of the increase in price levels.

description: Using molecular dynamics simulations, we study the motion of a closely fitting nanometer-size solid sphere in a fluid-filled cylindrical nanochannel at low Reynolds numbers and for a wide range of fluid-solid interactions corresponding to different wetting situations. For fluids that are not completely wetting we observe an interesting and novel adsorption phenomenon, in which the solid sphere, that was initially moving along the center of the tube, meanders across the channel and suddenly adsorbes onto the wall. Thereafter, the adsorbed sphere either {\it sticks} to the wall and remains motionless on average, or separates slightly from the tube wall and then moves parallel to the tube axis, while rotating on average. On the other hand, at short times, i.e. when the solid particle moves with its center close to the middle of the tube, we find surprisingly good agreement between our results and the predictions of the continuum approach in spite of the large thermal fluctuations present in our simulations.

description: We study the hadronic molecular structure of hidden heavy pentaquarks - new exotic states composed of charmed/bottom baryons and $D(D^*)/B(B^*)$ mesons. Based on the observation of three pentaquark candidates $P_c^+(4312)$, $P_c^+(4440)$, and $P_c^+(4457)$ by the LHCb Collaboration we consider the classification of possible flavor partners composed of charmed baryons and $D(D^*)$ mesons within the hadronic molecular approach. We extend this classification to the bottom sector. Using phenomenological Lagrangians we construct baryon-meson bound states governed by the Weinberg-Salam compositeness condition. As an application we consider strong two-body decays of the new exotic states into a light baryon and $V=J/ψ,Υ$ or $P=η_c,η_b$ mesons. Results are presented in the heavy quark limit.

description: We demonstrate that the ring of invariants for the natural action of a subgroup G of GL_n(F_q) on a polynomial ring R=K[X_1,...,X_n] need not be F-pure. In these examples G is the symplectic group over a finite field, and the invariant subrings are always complete intersections by the work of Carlisle and Kropholler. These examples are of special interest from the point of view of studying the Frobenius closures and tight closures of ideals as contractions from certain extension rings: they provide instances when the socle element modulo an ideal generated by a system of parameters is forced into the expansion of the ideal to a module-finite extension ring which is a separable (in fact, Galois) extension. This element is also forced into the expanded ideal in a linearly disjoint purely inseparable extension since it is in the Frobenius closure of the ideal. The second part of this paper studies the alternating group A_n acting on the polynomial ring R by permuting the variables. We determine when the ring of invariants for this action is F-regular.

description: Automated segmentation of kidneys and kidney tumors is an important step in quantifying the tumor's morphometrical details to monitor the progression of the disease and accurately compare decisions regarding the kidney tumor treatment. Manual delineation techniques are often tedious, error-prone and require expert knowledge for creating unambiguous representation of kidneys and kidney tumors segmentation. In this work, we propose an end-to-end boundary aware fully Convolutional Neural Networks (CNNs) for reliable kidney and kidney tumor semantic segmentation from arterial phase abdominal 3D CT scans. We propose a segmentation network consisting of an encoder-decoder architecture that specifically accounts for organ and tumor edge information by devising a dedicated boundary branch supervised by edge-aware loss terms. We have evaluated our model on 2019 MICCAI KiTS Kidney Tumor Segmentation Challenge dataset and our method has achieved dice scores of 0.9742 and 0.8103 for kidney and tumor repetitively and an overall composite dice score of 0.8923.

description: We present the soft X-ray spectrum of the LINER galaxy M81 derived from a long observation with the XMM RGS. The spectrum is dominated by continuum emission from the active nucleus, but also contains emission lines from Fe L, and H-like and He-like N, O, and Ne. The emission lines are significantly broader than the RGS point-source spectral resolution; in the cross dispersion direction the emission lines are detected adjacent to, as well as coincident with, the active nucleus. This implies that they originate in a region of a few arc-minutes spatial extent (1 arc-minute ~ 1 kpc in M81). The flux ratios of the OVII triplet suggest that collisional processes are responsible for the line emission. A good fit to the whole RGS spectrum is obtained using a model consisting of an absorbed power law from the active nucleus and a 3 temperature optically thin thermal plasma. Two of the thermal plasma components have temperatures of 0.18+-0.04 keV and 0.64+-0.04 keV, characteristic of the hot interstellar medium produced by supernovae; the combined luminosity of the plasma at these two temperatures accounts for all the unresolved bulge X-ray emission seen in the Chandra observation by Tennant et al. (2001). The third component has a higher temperature (~1.7 keV), and we argue that this, along with some of the 0.64 keV emission, comes from X-ray binaries in the bulge of M81.

description: To gain insight into the kinetics of colloidal gel evolution at low particle volume fractions $ϕ$, we utilize differential dynamic microscopy to investigate particle aggregation, geometric percolation, and the subsequent transition to nonergodic dynamics. We report the emergence of unexpectedly rich multiscale dynamics upon the onset of nonergodicity, which separates the wave vectors $q$ into three different regimes. In the high-$q$ domain, the gel exhibits $ϕ$-independent internal vibrations of fractal clusters. The intermediate-$q$ domain is dominated by density fluctuations at the length scale of the clusters, as evidenced by the $q$-independence of the relaxation time $τ$. In the low-$q$ domain, the scaling of $τ$ as $q^{-3}$ suggests that the network appears homogeneous. The transitions between these three regimes introduce two characteristic length scales, distinct from the cluster size.

description: The rice price support program (PSP) in Thailand is designed to support rice prices and raise incomes of rice farmers. However, it has been argued that the program only attracts participation from certain types of farmers, in particular larger and more efficient farmers with higher farm incomes. This raises the question of whether there is a difference in the technical efficiency of program participants and non-participants. This paper investigates two issues: (a) what are the key determinants of farmers’ decision to participate in the PSP? and (b) do program participants and non-participants use different rice production technologies and have different levels of technical efficiency. We take a stochastic frontier approach to answering these questions but because farmers self-select into the PSP the standard stochastic frontier model may lead to biased estimation. In response we augment the standard stochastic frontier model with a participation equation explaining the decision to participate in the PSP, and then use Heckman’s two-step estimation and Greene’s sample selection stochastic production frontier model to explore levels of technical efficiency among participants and non-participants. Results indicate that the participation decision is governed by key factors that include land size and the financial position of the farm. Results also show there is no strong evidence to support the presence of selectivity bias in the stochastic frontier estimates. In addition, a likelihood-ratio test indicates that participants and non-participants use the same frontier production technology. The analysis of technical efficiency reveals that participants are more technically efficient than non-participants. The findings therefore suggest that larger farmers participate more in the PSP and that these program participants tend to be more technically efficient farmers.

description: Genus Eosyntexis Rasnitsyn, 1990
 Type species: Eosyntexis senilis Rasnitsyn, 1990.
 Included species: E. senilis Rasnitsyn, 1990 from the Lower Cretaceous of Transbaikalia, E. tuffinae Rasnitsyn & Jarzembowski in Rasnitsyn et al., 1998 from the Lower Cretaceous (Berriasian in age) of England, E. catalonica Rasnitsyn & Martínez-Delclòs, 2000 and E. parva sp. n. from the Lower Cretaceous (Barremian and Albian in age, respectively) of Spain.
 New diagnosis of the genus. Forewing (Fig. 1 C-F, 2D) with pterostigma sclerotized; crossvein 1r-rs lost; cell 1mcu pentagonal or, if hexagonal, with one side very short; crossvein 2r-rs arising from the mid-part of pterostigma (not from near apex); M+Cu vein straight or slightly arched only very basally; section 3Cu shorter than 4Cu. Flagellomeres of the antenna less than twice as long as wide (Figs. 4A, C). Pronotum with distinct fore and upper faces meeting at angle (Fig. 3E). Propleura not elongated to form a distinct neck (Figs. 2B, 3A).
 Remarks. Within Syntexinae, Syntexis is the most distinct because of its flat pronotum, transparent (unsclerotized) pterostigma, R lost beyond pterostigma, 1r-rs retained, section 3Cu and cell 2a very long (longer than half of 1a). These characters are difficult to evaluate without a cladistic analysis, although they suggest that Eosyntexis is more closely related to Cretosyntexis than to Syntexis (except for the form of pronotum which is not known in sufficient detail for Cretosyntexis). Nevertheless, Eosyntexis is more like Syntexis than Cretosyntexis in some wing characters, such as having 2r-rs placed at pterostigmal mid-length (correlating with this, RS before it very long and arched near 1mcu), M+Cu straight and 1mcu pentagonal or almost so. Eosyntexis differs from the other genera in having flagellomeres comparatively short. The main similarity between Eosyntexis and Cretosyntexis lies in loss of 1r-rs and pronotum differentiated into fore and upper faces meeting at angle. Similarities between Syntexis and Eosyntexis are the straight M+Cu, the pentagonal 1mcu and the proximal position of 2r-rs. Finally, Syntexis and Cretosyntexis resemble each other in having long, narrow antennomeres. The exact relationships between the different genera are impossible to decide without a cladistic analysis.

Design Efficient Exponential Time Differencing method For Hodgkin-Huxley Neural Networks

Year: 2019
Subjects: subject: Neurons and Cognition (q-bio.NC)

description: The exponential time differencing (ETD) method allows using a large time step to efficiently evolve the stiff system such as Hodgkin-Huxley (HH) neural networks. For pulse-coupled HH networks, the synaptic spike times cannot be predetermined and are convoluted with neuron's trajectory itself. This presents a challenging issue for the design of an efficient numerical simulation algorithm. The stiffness in the HH equations are quite different between the spike and non-spike regions. Here, we design a second-order adaptive exponential time differencing algorithm (AETD2) for the numerical evolution of HH neural networks. Compared with the regular second-order Runge-Kutta method (RK2), our AETD2 method can use time steps one order of magnitude larger and improve computational efficiency more than ten times while excellently capturing accurate traces of membrane potentials of HH neurons. This high accuracy and efficiency can be robustly obtained and do not depend on the dynamical regimes, connectivity structure or the network size.

description: The authors describe a novel variety of spinning-rotor vacuum gauge in which the rotor is a ${\sim}4.7{\text -}μ$m-diameter silica microsphere, optically levitated. A rotating electrostatic field is used to apply torque to the permanent electric dipole moment of the silica microsphere and control its rotational degrees of freedom. When released from a driving field, the microsphere's angular velocity decays exponentially with a damping time inversely proportional to the residual gas pressure, and dependent on gas composition. The gauge is calibrated by measuring the rotor mass with electrostatic co-levitation, and assuming a spherical shape, confirmed separately, and uniform density. The gauge is cross-checked against a capacitance manometer by observing the torsional drag due to a number of different gas species. The techniques presented can be used to perform absolute vacuum measurements localized in space, owing to the small dimensions of the microsphere and the ability to translate the optical trap in three dimensions, as well as measurements in magnetic field environments. In addition, the dynamics of the microsphere, paired with a calibrated vacuum gauge, can be used to measure the effective molecular mass of a gas mixture without the need for ionization and at pressures up to approximately 1 mbar.

description: This article compares the growth-generating power of alternative agricultural development strategies in Madagascar. Projections from a semi-input-output model and a recently developed social accounting matrix suggest that both paddy and export crops stimulate strong linkages with other sectors of the Malagasy economy. But since paddy output can be increased at lower cost, investment in rehabilitating small irrigated rice perimeters generates 40% to 100% more GOP than a comparable investment in coffee production. Paddy also generates greater employment and a more equitable income distribution.

description: Recently developed machine learning techniques, in association with the Internet of Things (IoT) allow for the implementation of a method of increasing oil production from heavy-oil wells. Steam flood injection, a widely used enhanced oil recovery technique, uses thermal and gravitational potential to mobilize and dilute heavy oil in situ to increase oil production. In contrast to traditional steam flood simulations based on principles of classic physics, we introduce here an approach using cutting-edge machine learning techniques that have the potential to provide a better way to describe the performance of steam flood. We propose a workflow to address a category of time-series data that can be analyzed with supervised machine learning algorithms and IoT. We demonstrate the effectiveness of the technique for forecasting oil production in steam flood scenarios. Moreover, we build an optimization system that recommends an optimal steam allocation plan, and show that it leads to a 3% improvement in oil production. We develop a minimum viable product on a cloud platform that can implement real-time data collection, transfer, and storage, as well as the training and implementation of a cloud-based machine learning model. This workflow also offers an applicable solution to other problems with similar time-series data structures, like predictive maintenance.

description: This study entails an analysis of the technical efficiency of natural rubber production by state farms in Vietnam. A time-varying stochastic frontier production function model for unbalanced data is estimated for 33 farms. Individual farm technical efficiencies are reported and discussed. One of the main results concerns the bimodal distribution of technical efficiency indices. A few farms operate near the production frontier while the bulk operate well away from the frontier. Some implications are drawn from the results as a guide to future policy research work in the rubber industry in light of recent moves by the Vietnamese government towards economic reform.

Toward an Understanding of the Progenitors of Gamma-Ray Bursts
Creators: name: Bloom, Joshua S.
Publisher: name: arXiv
Year: 2003
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: The various possibilities for the progenitors of gamma-ray bursts (GRBs) manifest in differing observable properties. Through deep spectroscopic and high-resolution imaging observations of some GRB hosts, I demonstrate that well-localized long-duration GRBs are connected with otherwise normal star-forming galaxies at moderate redshifts of order unity. I test various progenitor scenarios by examining the offset distribution of GRBs about their apparent hosts, making extensive use of ground-based optical data from Keck and Palomar and space-based imaging from the Hubble Space Telescope. The offset distribution appears to be inconsistent with the coalescing neutron star binary hypothesis but statistically consistent with a population of progenitors that closely traces the ultra-violet light of galaxies. This is naturally explained by bursts which originate from the collapse of massive stars. This claim is further supported by the unambiguous detections of emission ''bumps'' which can be explained as supernovae that occur at approximately the same time as the associated GRB; if true, GRB 980326 and GRB 011121 provide strong observational evidence connecting cosmological GRBs to high-redshift supernovae and implicate massive stars as the progenitors of some long-duration GRBs. Interestingly, most alternative models of these bumps require wind-stratified circumburst media; this too, implicates massive stars. In addition to this work, I also constructed the Jacobs Camera (JCAM), a dual-beam optical camera for the Palomar 200-inch Telescope designed to follow-up rapid GRB localizations (abridged).

Risk and Uncertainty

description: Risk associated with the adoption of new maize technology and the impact of mandatory cotton production on traditional farmers in the Kasai Oriental Region of Zaire are evaluated within a portfolio context using a quadratic programming model. Seasonal net returns for farm plans including four levels of maize technology in combination with staple food crops are evaluated, with and without mandatory cotton production. The results indicate that cropping systems that include new maize technology are risk-efficient relative to local maize varieties while mandatory cotton production is not risk-efficient at the prevalent price and yield levels in the farming system.
Dynamics of modulated and composite aperiodic crystals: the signature of the inner polarization in the neutron coherent inelastic scattering

description: We compare within an unifying formalism the dynamical properties of modulated and composite aperiodic (incommensurate) crystals. We discuss the concept of inner polarization and we define an inner polarization parameter beta that distinguishes between different acoustic modes of aperiodic crystals. Although this concept has its limitations, we show that it can be used to extract valuable information from neutron coherent inelastic scattering experiments. Within certain conditions, the ratio between the dynamic and the static structure factors at various Bragg peaks depends on beta. We show how the knowledge of beta for modes of an unknown structure can be used to decide whether the structure is composite or modulated. Furthermore, the same information can be used to predict scattered intensity within unexplored regions of the reciprocal space, being thus a guide for experiments

description: To study materials phenomena simultaneously at various length scales, descriptions in which matter can be coarse grained to arbitrary levels, are necessary. Attempts to do this in the static regime (i.e. zero temperature) have already been developed. In this letter, we present an approach that leads to a dynamics for such coarse-grained models. This allows us to obtain temperature-dependent and transport properties. Renormalization group theory is used to create new local potentials model between nodes, within the approximation of local thermodynamical equilibrium. Assuming that these potentials give an averaged description of node dynamics, we calculate thermal and mechanical properties. If this method can be sufficiently generalized it may form the basis of a Molecular Dynamics method with time and spatial coarse-graining.

description: Detecting a signal from the Epoch of Reionisation (EoR) requires an exquisite understanding of galactic and extra-galactic foregrounds, low frequency radio instruments, instrumental calibration, and data analysis pipelines. In this work we build upon existing work that aims to understand the impact of calibration errors on 21-cm power spectrum (PS) measurements. It is well established that calibration errors have the potential to inhibit EoR detections by introducing additional spectral features that mimic the structure of EoR signals. We present a straightforward way to estimate the impact of a wide variety of modelling residuals in EoR PS estimation. We apply this framework to the specific case of broken dipoles in Murchison Widefield Array (MWA) to understand its effect and estimate its impact on PS estimation. Combining an estimate of the percentage of MWA tiles that have at least one broken dipole (15%-40%) with an analytic description of beam errors induced by such dipoles, we compute the residuals of the foregrounds after calibration and source subtraction. We find that that incorrect beam modelling introduces bias in the 2D-PS on the order of $\sim 10^3\, \mathrm{mK}^2 \,h^{-3}\, \mathrm{Mpc}^{3}$. Although this is three orders of magnitude lower than current lowest limits, it is two orders of magnitude higher than the expected signal. Determining the accuracy of both current beam models and direction dependent calibration pipelines is therefore crucial in our search for an EoR signal.

Demand and Price Analysis

description: Price response of maize acreage in Benin was estimated with a particular emphasis on whether the prices were producer prices in rural markets or retail prices in urban markets. A second difference between prices was examined through a price adjustment model which takes into account the distortions caused by local units on maize price when one is concerned with the pricing system in the private marketing network relating rural and urban areas. Urban market price specification appeared to be the most relevant statistically in explaining acreage decisions in Mono province. Price elasticity of acreage was 0.445 in this area while its value, around 0.10, was not significant for Benin as a whole. The use of adjusted urban prices enabled an increase of 5.6% of the elasticity in Mono province. The urban vs. rural difference was apparent, but the coefficients of the price variable were not significant in equations with rural prices. The latter were not as reliable as those of the urban market of Dantokpa (in Cotonou city) collected by the Institute of Statistics (INSAE) and the GTZ project.
Globally Optimal Selection of Ground Stations in Satellite Systems with Site Diversity

description: The availability of satellite communication systems is extremely limited by atmospheric impairments, such as rain (for radio frequencies) and cloud coverage (for optical frequencies). A solution to this problem is the site diversity technique, where a network of geographically distributed ground stations (GSs) can ensure, with high probability, that at least one GS is available for connection to the satellite at each time period. However, the installation of redundant GSs induces unnecessary additional costs for the network operator. In this context, we study an optimization problem that minimizes the number of required GSs, subject to availability constraints. First, the problem is transformed into a binary-integer-linear-programming (BILP) problem, which is proven to be NP-hard. Subsequently, we design a branch-and-bound (B&B) algorithm, with global-optimization guarantee, based on the linear-programming (LP) relaxation and a greedy method as well. Finally, numerical results show that the proposed algorithm significantly outperforms state-of-the-art methods, and has low complexity in the average case.

description: Quantum decay rates for barrier potentials driven by external stochastic and periodic forces in the strong damping regime are studied. Based on the recently derived quantum Smoluchowski equation [Phys. Rev. Lett. {\bf 87}, 086802 (2001)] explicit analytical and numerical results are presented for the case of the resonant activation phenomenon in a bistable potential and the escape from a metastablwell with oscillating barrier, respectively. The significant impact of quantum fluctuations is revealed.
