description: Genetic robustness is described as the capacity for a biological system to maintain the phenotype despite genetic modifications that could occur during replication. Mutational robustness is modulated by the codon usage, as synonymous codons differ in their propensity to mutate nonsynonymously and nonconservatively. With their error-prone polymerase, RNA viruses have elevated mutation rates and exist as a swarm of closely related sequences called quasispecies. During each replication cycle, many of the newly synthesised genomes differ from the consensus sequence, with possible deleterious effects on the viral population fitness. Viral populations can thus explore and occupy various regions of the genotypic sequence space, and their dynamics within this space greatly depends on the mutational robustness. Most published studies on viral robustness compared preexisting viruses, those being either “natural” strains or viruses engineered for other purposes. We chose a different approach for influenza viruses and decided to compare viruses specifically designed for their differences in robustness. The theoretical robustness (measured by the codon robustness indexes described by Dr Marco Archetti, University of Oxford, UK) of an H1N1pdm09 influenza virus was thus modified by rationally changing the codon usage within the PA gene, and the consequences on virus diversity and evolvability were studied.

description: We report the results of our search for pulsating subdwarf B stars in Full Frame Images, sampled at 30 min cadence and collected during Year 1 of the TESS mission. Year 1 covers most of the southern ecliptic hemisphere. The sample of objects we checked for pulsations was selected from a subdwarf B stars database available to public. Only two positive detections have been achieved, however, as a by-product of our search we found 1807 variable objects, most of them not classified, hence their specific variability class cannot be confirmed at this stage. Our preliminary discoveries include: two new subdwarf B (sdB) pulsators, 26 variables with known sdB spectra, 83 non-classified pulsating stars, 83 eclipsing binaries (detached and semi-detached), a mix of 1535 pulsators and non-eclipsing binaries, two novae, and 77 variables with known (non-sdB) spectral classification. Among eclipsing binaries we identified two known HW Vir systems and four new candidates. The amplitude spectra of the two sdB pulsators are not rich in modes, but we derive estimates of the modal degree for one of them. In addition, we selected five sdBV candidates for mode identification among 83 pulsators and describe our results based on this preliminary analysis. Further progress will require spectral classification of the newly discovered variable stars, which hopefully include more subdwarf B stars.

description: We report on two top-gate defined, coupled quantum dots in a semiconducting single wall carbon nanotube, constituting a tunable double quantum dot system. The single wall carbon nanotubes are contacted by titanium electrodes, and gated by three narrow top-gate electrodes as well as a back-gate. We show that a bias spectroscopy plot on just one of the two quantum dots can be used to extract the addition energy of both quantum dots. Furthermore, honeycomb charge stability diagrams are analyzed by an electrostatic capacitor model that includes cross capacitances, and we extract the coupling energy of the double quantum dot.

description: In this paper, we propose a distributed power control algorithm for addressing the global energy efficiency (GEE) maximization problem subject to satisfying a minimum target SINR for all user equipments (UEs) in wireless cellular networks. We state the problem as a multi-objective optimization problem which targets minimizing total power consumption and maximizing total throughput, simultaneously, while a minimum target SINR is guaranteed for all UEs. We propose an iterative scheme executed in the UEs to control their transmit power using individual channel state information (CSI) such that the GEE is maximized in a distributed manner. We prove the convergence of the proposed iterative algorithm to its corresponding unique fixed point also shown by our numerical results. Additionally, simulation results demonstrate that our proposed scheme outperforms other algorithms in the literature and performs like the centralized algorithm executed in the base station and maximizes the GEE using the global CSI.

description: After a pandemic wave in 2009 following its introduction in the human population, H1N1pdm09 subtype replaced the previously circulating H1N1 virus and, along with the H3N2 subtype, is now responsible for the seasonal type A influenza epidemics. So far, the evolutionary potential of influenza viruses has been mainly documented by consensus sequencing data. However, RNA virus polymerases are considered to have low fidelity, and a virus thus exists as a cloud of closely related sequences, which could influence its fitness and its adaptability. Interest in this quasispecies nature has increased with the development of next-generation sequencing (NGS) technologies that allow a wider study of the genetic variability. NGS deep-sequencing methodologies were developed to determine the whole-genome genetic heterogeneity of the 3 subtypes of influenza type A viruses that circulated in humans between 2007 and 2012 in France, directly from nasal swab samples. We are presenting here the results of the comparison performed to identify subtype/severity signatures focusing on mutation frequencies and specific nucleotide polymorphisms.

description: For each genomic viral RNA (vRNA) composing the segmented genome of influenza viruses, the coding region is flanked by non-coding (NC) sequences. Each end can be divided into a conserved part, whose sequence is common to all the viral segments and specific for each type, and a non-conserved part. The length of this non-conserved sequence is very variable between segments and between influenza virus types. Within each genomic RNA molecule, the 3’ and 5’ ends associate to form two possible secondary structures: the ‘panhandle structure’ and the ‘corkscrew structure’. These structures are known to be critical for the transcription and the replication of the vRNAs. Based on reverse genetic systems available for both type A and C influenza viruses, we attempted to rescue infectious viruses, for which one or both NC regions of the NP segment were exchanged between type A and C influenza viruses. This approach was used to demonstrate the importance of the panhandle structure in type specificity; more specifically of the proximal panhandle sequence and of the initial distal panhandle strength. Thus, both elements were found to be compulsory to rescue infectious viruses. Interestingly, in type A influenza virus infectious context, we also found that the length of the NP segment 5’ NC region once transcribed into mRNA impacts its translation, and that the level of produced NP protein consequently affects the level of viral genome replication.

description: Planets form and obtain their compositions in disks of gas and dust around young stars. The chemical compositions of these planet-forming disks regulate all aspects of planetary compositions from bulk elemental inventories to access to water and reactive organics, i.e. a planet's hospitality to life and its chemical origins. Disk chemical structures are in their turn governed by a combination of {\it in situ} chemical processes, and inheritance of molecules from the preceding evolutionary stages of the star formation process. In this review we present our current understanding of the chemical processes active in pre- and protostellar environments that set the initial conditions for disks, and the disk chemical processes that evolve the chemical conditions during the first million years of planet formation. We review recent observational, laboratory and theoretical discoveries that have led to the present view of the chemical environment within which planets form, and their effects on the compositions of nascent planetary systems. We also discuss the many unknowns that remain and outline some possible pathways to addressing them.

description: We observe the decay B0 to p pbar K*0 with a branching fraction of (1.18^{+0.29}_{-0.25} (stat.) \pm 0.11 (syst.)) \times 10^{-6}. The statistical significance is 7.2 sigma for the signal in the low ppbar mass region. We study the decay dynamics of B0 to p pbar K*0 and compare it with B+ to p pbar K*+. The K*0 meson is found to be almost 100% polarized (with a fraction of (101 \pm 13 \pm 3)% in the helicity zero state), while the K*+ meson has a (32 \pm 17 \pm 9)% fraction in the helicity zero state. The direct CP asymmetries for B0 to p pbar K*0 and B+ to p pbar K*+ are measured to be -0.08\pm 0.20\pm 0.02 and -0.01\pm 0.19\pm 0.02, respectively. We also study the characteristics of the low mass ppbar enhancements near threshold and the associated angular distributions. In addition, we report improved measurements of the branching fractions BF(B+ to p pbar K*+) = (3.38^{+0.73}_{-0.60} \pm 0.39) \times 10^{-6} and BF(B0 to p pbar K0) = (2.51^{+0.35}_{-0.29} \pm 0.21) \times 10^{-6}, which supersede our previous measurements. These results are obtained from a 492 fb^{-1} data sample collected near the Upsilon(4S) resonance with the Belle detector at the KEKB asymmetric-energy e^+ e^- collider.

Metaphysical Dimensions of Arabesque by Germaine Dulac in the Context of Black Square by Kazimir Malevich

description: In this chapter of my PhD thesis I follow the visual similarities between abstract images in Arabesque by Dulac and Suprematist paintings by Malevich. In doing so, I try to find out if the meaning of the first ones can go beyond psychological and social meanings usually attributed to them and enter the sphere of metaphysical issues. To answer this question, I examine the role of light and Dulac’s method of using it in abstract images. In ‘Background, Inspirations, Early Work’ I briefly present her life, art circles she was involved with, and influences which inspired her work. I define the main sources of her creative impulses and crucial points of interests, stressing the specific use of light, whose power of expression she discovered in Symbolist theatre and Pre-Raphaelite paintings. This is illustrated with the examples of films in which she uses light to render emotions, reveal the inner world of the protagonists and create the ambient of her works. In ‘Motif of Light’ I start with her earliest works, where one can already notice a tendency to use light for abstracting the image. Her ultimate turn towards pure cinema in 1929 brings the change of optics from figurative to abstract. I argue that it is not rhythm, as usually suggested, but a specific use of light which plays a crucial role in this shift. In ‘Arabesque, Black Square and Table’, a piece of poetic text helps me to look at the three different images: Black Square (1915) by Malevich, Arabesque (1929) by Dulac and my own film Table (2015), dwelling on subtle relations between these artworks and setting up a common ground for reflection. What comes to the fore in these pieces is the role of light in changing an object into a “figure”. Dulac’s method of abstracting objects understood as means of “translating certain ideas” (Williams, 2007a, p. 94) is contrasted then with the idea of freeing an object from the indexical bonds, which happens in Malevich’s Black Square (Bulgakova, 2002). This strategy lets me examine if abstract images in Arabesque transcendent the previous indexical attachments. The section ‘Light and Matter’ concentrates on the analytical character of Dulac’s works. To understand this issue, abstract images from her film are placed against a broader intellectual background of the epoch. I analyse the idea of the identity of image and movement (Bergson, Matter and Memory, 1896), and Einstein’s equation between light and matter developed around that time and later adopted to the reflection on cinema (Bergson, Duration and Simultaneity, 1922; Deleuze, Cinema 1, 1983). The idea of the ontological unity of these elements, when applied to the Dulac’s images, stresses their metaphysical character.

description: We investigate the effectiveness of coarse-grained molecular dynamics simulations to estimate binding free energy as a scoring method to identify stable binding conformations out of docking decoys from 19 000 docked protein conformations, or ‘decoys’, for 15 benchmark targets from the Critical Assessment of Predicted Interactions (CAPRI). For most of the targets, our method can enrich acceptable or higher quality structures. In the top 100 scored decoys, our method obtains a higher fraction of acceptable or better for all 'easy' targets, and also for several 'hard' targets, as compared to other scoring methods. From estimates of the error, we expect we can improve accuracy by extending the amount of sampling done at each distance. This can be approved by increasing sampling, but this remains very expensive.
Two-magnon excitations in resonant inelastic x-ray scattering from quantum Heisenberg antiferromagnets

description: We study two-magnon spectra in resonant inelastic x-ray scattering (RIXS) from the Heisenberg antiferromanets by extending the formula of Nomura andIgarashi (Phys. Rev. B 71, 035110 (2005)). The core-hole potential in the intermediate state of RIXS gives rise to a change in the exchange coupling between 3d electrons, leading to an effective interaction between the core hole and spins of 3d electrons. We derive a formula suitable to calculate the two-magnon RIXS intensities, replacing the bare core-hole potential responsible to charge excitations by this effective interaction creating two magnons in our previous formula. It consists of two factors, one of which determines the incident-photon-energy dependence and another is the two-magnon correlation function. We evaluate the former factor for La_{2}CuO_{4} in terms of the density of states of the 4p states obtained by the band calculation. We also calculate the two-magnon correlation function as a function of energy loss ωand momentum transfer \textbf{q} of the Heisenberg model on a square lattice,by summing up the ladder diagrams after transforming the magnon-magnon interaction into a separable form. The calculated spectra form a broad peak around ω=3J for S=1/2 on the magnetic Brillouin zone boundary and vanish at \textbf{q}=(0,0) and (π,π). Such momentum dependence of the RIXS spectra could provide an excellent opportunity to study the dynamics in the Heisenberg model.

description: We report on a new measurement of the cosmic ray (CR) electron and positron spectra in the energy range of 20 MeV -- 1 GeV. The data were taken during the first flight of the balloon-borne spectrometer AESOP-Lite (Anti Electron Sub Orbital Payload), which was flown from Esrange, Sweden, to Ellesmere Island, Canada, in May 2018. The instrument accumulated over 130 hours of exposure at an average altitude of 3 g.cm$^{-2}$ of residual atmosphere. The experiment uses a gas Cherenkov detector and a magnetic spectrometer, consisting of a permanent dipole magnet and silicon strip detectors (SSDs), to identify particle type and measure the rigidity. Electrons and positrons were detected against a background of protons and atmospheric secondary particles. The primary cosmic ray spectra of electrons and positrons, as well as the re-entrant albedo fluxes, were extracted between 20 MeV -- 1 GeV during a positive solar magnetic polarity epoch. The positron fraction below 100 MeV appears flat, suggesting diffusion dominated solar modulation at low rigidity. The all-electron spectrum is presented and compared with models from a heliospheric numerical transport code.

We use the Ricci curvature criterion to study the degree of relative chaos (exponential instability) in core-halo gravitating configurations. We show the existence of a critical core radius when the system is least chaotic, while systems with both smaller and larger core radius will typically possess stronger chaotic properties.

Comparison to results for the Au+Au collisions at the same energies shows a reduction of about 20% in the flow observed for a centrality selection of 0-40%. The centrality dependent flow, expressed as a function of the number of participants N_part, is compared for the Cu+Cu and Au+Au systems using two definitions of eccentricity, the standard definition epsilon_standard and a participant eccentricity epsilon_part. The v2 / as a function of N_part, for the Au+Au and Cu+Cu collisions are consistent within errors, while v2 / gives unrealistically large values for Cu+Cu, especially for central collision.

description: Several large neutrino telescopes, operating at various sites around the world, have as their main objective the first detection of neutrinos emitted by a gravitational collapse in the Milky Way. The success of these observation programs depends on the rate of supernova core collapse in the Milky Way, $R$. In this work, standard statistical techniques are used to combine several independent results. Their consistency is discussed and the most critical input data are identified. The inference on $R$ is further tested and refined by including direct information on the occurrence rate of gravitational collapse events in the Milky Way and in the Local Group, obtained from neutrino telescopes and electromagnetic surveys. A conservative treatment of the errors yields a combined rate $R=1.63 \pm 0.46$ (100 yr)$^{-1}$; the corresponding time between core collapse supernova events turns out to be $T=61_{-14}^{+24}$~yr. The importance to update the analysis of the stellar birthrate method is emphasized.

description: No abstracts are to be cited without prior reference to the author.Bottom trawls are a globally used fishing gear that physically disturb the seabed and kill nontarget organisms, including those that are food for the targeted fish species. There are indications that ensuing changes to the benthic invertebrate community may increase the availability of food and promote growth and even fisheries yield of target fish species. If and how this occurs is the subject of ongoing debate, with evidence both in favour and against. We model the effects of trawling on a simple ecosystem of benthivorous fish and two food populations (benthos), susceptible and resistant to trawling. We show that the ecosystem response to trawling depends on whether the abundance of benthos is top-down or bottom-up controlled. Fishing can results in higher fish abundance and higher (maximum sustainable) yield in a bottom-up controlled system, where resistant benthos are sufficiently less affected by trawling than susceptible benthos, while being the most profitable prey. Fishing leads to lower fish abundance and yields for all other cases studied, in both top-down and bottom-up controlled systems. This highlights the importance of mechanistic ecosystem knowledge as a requirement for successful management.

description: Deep learning-based methods have achieved promising performance in early detection and classification of lung nodules, most of which discard unsure nodules and simply deal with a binary classification -- malignant vs benign. Recently, an unsure data model (UDM) was proposed to incorporate those unsure nodules by formulating this problem as an ordinal regression, showing better performance over traditional binary classification. To further explore the ordinal relationship for lung nodule classification, this paper proposes a meta ordinal regression forest (MORF), which improves upon the state-of-the-art ordinal regression method, deep ordinal regression forest (DORF), in three major ways. First, MORF can alleviate the biases of the predictions by making full use of deep features while DORF needs to fix the composition of decision trees before training. Second, MORF has a novel grouped feature selection (GFS) module to re-sample the split nodes of decision trees. Last, combined with GFS, MORF is equipped with a meta learning-based weighting scheme to map the features selected by GFS to tree-wise weights while DORF assigns equal weights for all trees. Experimental results on the LIDC-IDRI dataset demonstrate superior performance over existing methods, including the state-of-the-art DORF.

description: We present a transmission spectrum for the warm (500-600K) sub-Neptune HD3167c obtained using the Hubble Space Telescope Wide Field Camera 3 infrared spectrograph. We combine these data, which span the 1.125-1.643 micron wavelength range, with broadband transit measurements made using Kepler/K2 (0.6-0.9 micron) and Spitzer/IRAC (4-5 micron). We find evidence for absorption by at least one of H2O, HCN, CO2, and CH4 (Bayes factor 7.4; 2.5-sigma significance), although the data precision does not allow us to unambiguously discriminate between these molecules. The transmission spectrum rules out cloud-free hydrogen-dominated atmospheres with metallicities <100x solar at >5.8-sigma confidence. In contrast, good agreement with the data is obtained for cloud-free models assuming metallicities >700x solar. However, for retrieval analyses that include the effect of clouds, a much broader range of metallicities (including subsolar) is consistent with the data, due to the degeneracy with cloud-top pressure. Self-consistent chemistry models that account for photochemistry and vertical mixing are presented for the atmosphere of HD3167c. The predictions of these models are broadly consistent with our abundance constraints, although this is primarily due to the large uncertainties on the latter. Interior structure models suggest the core mass fraction is >40%, independent of a rock or water core composition, and independent of atmospheric envelope metallicity up to 1000x solar. We also report abundance measurements for fifteen elements in the host star, showing that it has a very nearly solar composition.

Relativistic RPA plus phonon-coupling analysis of pygmy dipole resonances

description: The relativistic random-phase approximation (RRPA) plus phonon-coupling (PC) model is applied in the analysis of E1 strength distributions in $^{208}$Pb and $^{132}$Sn, for which data on pygmy dipole resonances (PDR) have recently been reported. The covariant response theory is fully consistent: the effective nuclear interaction NL3 is used both to determine the spectrum of single-nucleon Dirac states, and as the residual interaction which determines the collective phonon states in the relativistic RPA. It is shown that the picture of the PDR as a resonant oscillation of the neutron skin against the isospin saturated proton-neutron core, and with the corresponding RRPA state characterized by a coherent superposition of many neutron particle-hole configurations, remains essentially unchanged when particle-vibration coupling is included. The effect of two-phonon admixtures is a weak fragmentation and a small shift of PDR states to lower excitation energy. Even though the PDR calculated in the extended model space of $ph \otimes$phonon configurations contains sizeable two-phonon admixtures, it basically retains a one-phonon character and its dynamics is not modified by the coupling to low-lying surface vibrations.

description: This paper describes the database of optical spectra of BL Lacertae (BLL) objects ZBLLAC available at the URL https://web.oapd.inaf.it/zbllac/. At the present date, it contains calibrated spectra for 295 BLL. For about 35% of them, we report a firm measure of redshift z while for 35 sources we set a lower limit on z based on the detection of intervening absorption systems, mainly ascribed to Mg II (2800 Ang). We report here on the architecture of the database and on its web front-end that permits to filter, query and interactively explore the data. We discuss some properties of the objects in the present dataset by giving the distribution of the redshifts and reporting on the detected emission lines, which turn out to be mainly forbidden and ascribed to [O II] (3737 Ang) and [O III] (5007 Ang). Finally, we discuss on intervening absorption systems detected in 35 BLLs that allow us to set lower limits to their distance.

description: Deep Convolutional Neural Networks (CNNs) have become state-of-the art for computer vision and other signal processing tasks due to their superior accuracy. In recent years, large efforts have been made to reduce the computational costs of CNNs in order to achieve real-time operation on low-power embedded devices. Towards this goal we present BinArray, a custom hardware accelerator for CNNs with binary approximated weights. The binary approximation used in this paper is an improved version of a network compression technique initially suggested in [1]. It drastically reduces the number of multiplications required per inference with no or very little accuracy degradation. BinArray easily scales and allows to compromise between hardware resource usage and throughput by means of three design parameters transparent to the user. Furthermore, it is possible to select between high accuracy or throughput dynamically during runtime. BinArray has been optimized at the register transfer level and operates at 400 MHz as instruction-set processor within a heterogenous XC7Z045-2 FPGA-SoC platform. Experimental results show that BinArray scales to match the performance of other accelerators like EdgeTPU [2] for different network sizes. Even for the largest MobileNet only 50% of the target device and only 96 DSP blocks are utilized.

description: We focus on the superfield formulation for a N = 2 vector supermultiplet in two dimensional spacetime and explicitly show that the Wess-Zumino gauge condition for a N = 2 superfield is compatible with familiar SUSY (plus U(1) gauge) transformations for the vector supermultiplet. N = 2 SUSY invariant mass and Yukawa interaction terms for the vector supermultiplet are also constructed from the superfield explicitly in addition to a free (kinetic) action.

Ecosystem observation, processes and dynamics

description: No abstracts are to be cited without prior reference to the author. The capability to disentangle ecosystem responses due to fishing pressure from those related to other (natural or anthropogenic) drivers remains a tricky and intriguing issue. The need to implement of Ecosystem-based Fisheries Management in marine ecosystems and the recent adoption of EU Directives, such as the Marine Strategy Framework Directive (MSFD), make this issue particularly relevant. In this context, important efforts have been devoted to the development of new indicators. In this field, a promising approach is emerging that analyzes energy accumulation into various biomass components of an ecosystem. Analysis of biomass accumulation across trophic levels (TL) was executed for landings time series (1970-2008) in eight Mediterranean Sea basins. The standardized cumulative biomass versus TL curves for each year have been fitted to logistic functions. These parameters have then been analyzed with possible explanatory variables to better elucidate the main drivers of these ecosystems. These variables include geographical (latitude, longitude and depth), climatic (NAO, WeMO and SST), production related (PAR and Chl a) and anthropogenic forcing (i.e. ecosystem overfishing, the fishery dependent L index) factors. Preliminary results obtained by the integration of a mixed model with model averaging approach are encouraging: they indicated a specificity of the different curve parameters which consistently respond to the external drivers depending upon common features of these marine ecosystems.
Beegle: from literature mining to disease gene discovery
Creators: name: ElShal, Sarah
Publisher: name: F1000Research

description: Disease-gene identification is a challenging process that has multiple applications within functional genomics and personalized medicine. Typically, this process involves both finding genes known to be associated with the disease (through literature search) and carrying out preliminary experiments or screens (e.g. linkage or association studies, copy number analysis, expression profiling) to determine a set of promising candidates for experimental validation. This requires extensive time and monetary resources. We describe Beegle, an online search and discovery engine that attempts to simplify this process by automating the typical approaches. It starts by mining the literature to quickly extract a set of genes known to be linked with a given query, then it integrates the learning methodology of Endeavour (a gene prioritization tool) to train a genomic model and rank a set of candidate genes to generate novel hypothesis. In a realistic evaluation setup, Beegle has an average recall of 84% at the top 100 returned genes as a search engine, which improves the discovery engine by 12.6% at the top 5% prioritized genes. Beegle is publicly available at http://beegle.esat.kuleuven.be/.

description: No abstracts are to be cited without prior reference to the author. Patterns of coexistence among competing species that exhibit size- and food-dependent growth remain largely unexplored. Here we study mechanisms behind shifts in competitive dominance and mechanisms causing alternative stable states in a size-structured fish community. We use a framework of physiologically structured population models, applied to competing populations representing sprat and herring stocks in the Baltic Sea. Degree of resource overlap and size-dependent mortality were studied as functions of resource productivity. We found that the identity of the dominant species in our model system shifted between low and high productivity, but that the importance of varying productivity was dependent on mortality level. In addition, we show how population cycles driven by size-based competitive asymmetries may result in priority effects leading to alternative stable community states, including one-species states and a state where sprat and herring could coexist. To better understand how changes in major ecosystem drivers, such as resource productivity and mortality, influence community structure and dynamics in exploited marine fish communities we argue that accounting for size- and food-dependent development is necessary.
