description: Daylily (Hemerocallis citrina Borani), a widespread ornamental plant around the world, has been considered as an ideal model to study flower development recently. To initiate the research to comprehensively investigate the molecular mechanism of the flower development of daylily, we performed a transcriptome sequencing study to establish the transcriptional profiles of this plant at different flower developmental stages. Briefly, we divided the flower development of daylily into six stages, and performed transcriptome sequencing for the samples collected from each stage. A total of 56,598 unique transcripts were obtained, of which 35,424 ones (about 62.6%) encode proteins with known functions based on homology searches against well-studied model plants. The expression profiles of these genes showed that 7,395 genes were differentially expressed during flower development. Further functional enrichment analysis for these differentially expressed genes revealed that they are enriched in the processes of translation, oxidation-reduction, and cell wall metabolism, suggesting the critical roles of these processes in daylily flower development.

On dilaton solutions of de Sitter inflation and primordial spin-torsion density fluctuations

description: Four classes of exact solutions of Einstein-Cartan dilatonic inflationary de Sitter cosmology are given.The first is obtained from the equation of state of massless dilaton instead of an unpolarized fermion fluid used previously by Gasperini.Repulsive gravity is found in the case where dilatons are constraint by the presence of spin-torsion effects.The second and third solutions represent respectively massive dilatons in the radiation era with the massive potential and torsion kinks and finally the dust of spinning particles.Primordial spin-density fluctuations are also computed based on Primordial fluctuations of temperature obtained from COBE data.The temperature fluctuation can also be computed from the nearly flat spectrum of the gravitational waves produced during inflation and by the result that the dilaton mass would be proportional to the Hubble constant.This result agrees with the COBE data.This idea is also used to compute the spin-torsion density in the inflation era.

description: Tuberculosis (TB) is a life-threatening disease caused by the deposition of Mycobacterium tuberculosis in the lungs. The overuse of antibiotics has led to a prevalence of antibiotic resistant M. tuberculosis strains, encouraging the investigation of bacteriophage therapy as a novel treatment. This study aims to isolate and characterize a novel lytic phage that can eventually be used to treat Tuberculosis in vivo, by testing phage propagation under growth parameters mimicking the human lung microenvironment. M. smegmatis, a close, non-pathogenic relative of M. tuberculosis served as the host species for these experiments. The four conditions, temperature (30˚C and 35˚C), pH level (5.5-8.5), oxygen concentration (anaerobic and aerobic), and mucus viscosity (varying thickness) were tested by performing plaque assays using purified phage. Phage lysis activity was measured by calculating plaque forming units (PFU) per mL, and Grungle was found to successfully propagate under each condition tested. Statistical ANOVA single-factor tests were performed to assess significant changes in PFU/mL for each independent variable tested. These tests showed insignificant differences in PFU/mL, suggesting that Phage Grungle’s lysis activity remained undisturbed by the changes in the various growth parameters tested. Comparative genome analyses revealed that Cluster C phages, including Grungle, were unable to infect Mycobacterium tuberculosis. However, the presence of a novel immunity repressor gene may contribute to Grungle’s lysis efficiency in other phages. The results of this study show that Phage Grungle has the potential to be utilized as an alternative treatment to antibiotics in eliminating bacterial infections in afflicted individuals, as well as being a useful resource for the continued study of phage biology.

description: The energy efficiency aspect of cellular networks is a vital topic of research over the recent days. As energy consumption is on the rise and the price of electricity is increasing very rapidly, necessity to reduce electricity usage in every aspect is becoming much more significant. The power grid infrastructure, from which the cellular networks attain the required electricity for operation is considering a significant change from the traditional electricity grid to the smart grid. The base stations, which are the main candidates for energy consumption in cellular networks, remain in operation even when there are a very few users or no user at all. In this paper, we propose an effective application scenario of the femtocell technology for power saving purpose of cellular networks. Effective deployment of femto-access-points in the required places can reduce the power usage of cellular networks by turning off the redundant base stations. Moreover, the signal to noise plus interference ratio is also enhanced in comparison to the traditional scheme. The base station turn off probability and the energy consumption in the overall network are analyzed. The comparison results show that the proposed energy efficient model can significantly reduce energy consumption and increase the service quality of the cellular users.

description: We investigate the dynamics of the recently proposed model of assisted inflation. In this model an arbitrary number of scalar fields with exponential potentials evolve towards an inflationary scaling solution, even if each of the individual potentials is too steep to support inflation on its own. By choosing an appropriate rotation in field space we can write down explicitly the potential for the weighted mean field along the scaling solution and for fields orthogonal to it. This demonstrates that the potential has a global minimum along the scaling solution. We show that the potential close to this attractor in the rotated field space is analogous to a hybrid inflation model, but with the vacuum energy having an exponential dependence upon a dilaton field. We present analytic solutions describing homogeneous and inhomogeneous perturbations about the attractor solution without resorting to slow-roll approximations. We discuss the curvature and isocurvature perturbation spectra produced from vacuum fluctuations during assisted inflation.

Role of NMDA conductance in average firing rate shifts caused by external periodic forcing

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

description: A widely accepted view of computations in the brain relies on population coding, where the neural ensemble firing rate is modulated in a stable manner to transmit information and perform various cognitive tasks. At the same time, oscillatory neural activity is specifically modulated in frequency, coherence and power during cognitive performance. How the firing rate and oscillations interact remains a salient question. In this paper, we develop a theory for the interactions between oscillatory signals and the firing rate of neural populations based on activity of non-linear voltage-dependent NMDA synapses. Notably, we show under which conditions oscillatory inputs can control the mean firing rate without loss of stability. Using mathematical analysis and simulations of mean-field models, we demonstrate that presence of NMDA synapses on both the excitatory and the inhibitory neurons is critical for sinusoidal oscillations to significantly and stably increase the firing rate. We characterize the oscillation-induced mean firing rate shift as a function of the fast and slow synaptic weights and demonstrate the parameter region, in which the effect under investigation is mostly pronounced. Results of our work may help identify the properties of neural circuits that allow for constructive control of the firing rate codes by large-scale neural oscillations.
On free evolution of self gravitating, spherically symmetric waves

description: We perform a numerical free evolution of a selfgravitating, spherically symmetric scalar field satisfying the wave equation. The evolution equations can be written in a very simple form and are symmetric hyperbolic in Eddington-Finkelstein coordinates. The simplicity of the system allow to display and deal with the typical gauge instability present in these coordinates. The numerical evolution is performed with a standard method of lines fourth order in space and time. The time algorithm is Runge-Kutta while the space discrete derivative is symmetric (non-dissipative). The constraints are preserved under evolution (within numerical errors) and we are able to reproduce several known results.

description: Organometallic compounds constitute a very large group of substances that contain at least one metal-to-carbon bond in which the carbon is part of an organic group. They have played a major role in the development of the science of chemistry. These compounds are used to a large extent as catalysts (substances that increase the rate of reactions without themselves being consumed) and as intermediates in the laboratory and in industry. Recently, novel quantum phenormena such as topological insulators and superconductors were also suggested in these materials. However, there has been no report on the experimental exploration for the topological state. Evidence for superconductivity from the zero-resistivity state in any organometallic compound has not been achieved yet, though much efforts have been devoted. Here we report the experimental realization of superconductivity with the critical temperature of 3.6 K in a potassium-doped organometallic compound, $ i.e.$ tri-$o$-tolylbismuthine with the evidence of both the Meissner effect and the zero-resistivity state through the $dc$ and $ac$ magnetic susceptibility and resistivity measurements. The obtained superconducting parameters classify this compound as a type-II superconductor. The benzene ring is identified to be the essential superconducting unit in such a phenyl organometallic compound. The superconducting phase and its composition are determined by the combined studies of the X-ray diffraction and theoretical calculations as well as the Raman spectroscopy measurements. These findings enrich the applications of organometallic compounds in superconductivity and add a new electron-acceptor family for organic superconductors. This work also points to a large pool for finding superconductors from organometallic compounds.

description: We report on numerical results from an independent formalism to describe the quasi-equilibrium structure of nonsynchronous binary neutron stars in general relativity. This is an important independent test of controversial numerical hydrodynamic simulations which suggested that nonsynchronous neutron stars in a close binary can experience compression prior to the last stable circular orbit. We show that, for compact enough stars the interior density increases slightly as irrotational binary neutron stars approach their last orbits. The magnitude of the effect, however, is much smaller than that reported in previous hydrodynamic simulations.

description: The rise of blockchain technologies has given a boost to social good projects, which are trying to exploit various characteristic features of blockchains: the quick and inexpensive transfer of cryptocurrency, the transparency of transactions, the ability to tokenize any kind of assets, and the increase in trustworthiness due to decentralization. However, the swift pace of innovation in blockchain technologies, and the hype that has surrounded their "disruptive potential", make it difficult to understand whether these technologies are applied correctly, and what one should expect when trying to apply them to social good projects. This paper addresses these issues, by systematically analysing a collection of 120 blockchain-enabled social good projects. Focussing on measurable and objective aspects, we try to answer various relevant questions: which features of blockchains are most commonly used? Do projects have success in fund raising? Are they making appropriate choices on the blockchain architecture? How many projects are released to the public, and how many are eventually abandoned?

description: We use a multifractal formalism to study the effect of stochastic resonance in a noisy bistable system driven by various input signals. To characterize the response of a stochastic bistable system we introduce a new measure based on the calculation of a singularity spectrum for a return time sequence. We use wavelet transform modulus maxima method for the singularity spectrum computations. It is shown that the degree of multifractality defined as a width of singularity spectrum can be successfully used as a measure of complexity both in the case of periodic and aperiodic (stochastic or chaotic) input signals. We show that in the case of periodic driving force singularity spectrum can change its structure qualitatively becoming monofractal in the regime of stochastic synchronization. This fact allows us to consider the degree of multifractality as a new measure of stochastic synchronization also. Moreover, our calculations have shown that the effect of stochastic resonance can be catched by this measure even from a very short return time sequence. We use also the proposed approach to characterize the noise-enhanced dynamics of a coupled stochastic neurons model.

description: Coalescence is a major model used to describe the formation of light (anti)nuclei in high-energy collisions. It is based on the assumption that two nucleons close in phase space can coalesce and form a nucleus. Antideuteron and antihelium nuclei have been proposed as a detection channel for dark matter annihilations and decays in the Milky Way, due to the low astrophysical background expected. In order to correctly interpret any future antinuclei measurement in space, the production of antinuclei has to be well understood. In this Master’s Thesis, a more advanced approach is employed combining event-by-event Monte Carlo simulations with a microscopic coalescence picture based on the Wigner function formalism. The antiproton production in the event generator EPOS 3 and the transport model SMASH is compared to measurements from the STAR Collaboration.

Possible ways to account for the impurity charge compensation are discussed. Calculations are done in the local density approximation (LDA) and, for better description of Coulomb correlation effects within the localized impurity states, also in the LDA+U scheme. The achievements and problems encountered in both approaches are analyzed. It is found that the impurity possess either a low-spin configuration (with 0 or 1 compensating electron), or a high-spin configuration (with 2 or 3 compensating electrons), the latter two apparently corresponding to practically relevant rechargeable impurity states.

description: We propose a method for the weakly supervised detection of objects in paintings. At training time, only image-level annotations are needed. This, combined with the efficiency of our multiple-instance learning method, enables one to learn new classes on-the-fly from globally annotated databases, avoiding the tedious task of manually marking objects. We show on several databases that dropping the instance-level annotations only yields mild performance losses. We also introduce a new database, IconArt, on which we perform detection experiments on classes that could not be learned on photographs, such as Jesus Child or Saint Sebastian. To the best of our knowledge, these are the first experiments dealing with the automatic (and in our case weakly supervised) detection of iconographic elements in paintings. We believe that such a method is of great benefit for helping art historians to explore large digital databases.

description: Arbuscular mycorrhizal fungi are asexual, obligately symbiotic fungi with unique morphology and genomic structure, which occupy a dual niche, that is, the soil and the host root. Consequently, the direct adoption of models for community assembly developed for other organism groups is not evident. In this paper we adapted modern coexistence and assembly theory to arbuscular mycorrhizal fungi. We review research on the elements of community assembly and coexistence of arbuscular mycorrhizal fungi, highlighting recent studies using molecular methods. By addressing several points from the individual to the community level where the application of modern community ecology terms runs into problems when arbuscular mycorrhizal fungi are concerned, we aim to account for these special circumstances from a mycocentric point of view. We suggest that hierarchical spatial structure of arbuscular mycorrhizal fungal communities should be explicitly taken into account in future studies. The conceptual framework we develop here for arbuscular mycorrhizal fungi is also adaptable for other host-associated microbial communities.

description: Soil aggregation, a key component of soil structure, has mostly been examined from the perspective of soil management and the mediation of ecosystem processes such as soil carbon storage. However, soil aggregation is also a major factor to consider in terms of the fine-scale organization of the soil microbiome. For example, the physico-chemical conditions inside of aggregates usually differ from the conditions prevalent in the bulk soil and aggregates therefore increase the spatial heterogeneity of the soil. In addition, aggregates can provide a refuge for microbes against predation since their interior is not accessible to many predators. Soil aggregates are thus clearly important for microbial community ecology in soils (for example, Vos et al., 2013; Rillig et al., 2016) and for microbially driven biogeochemistry, and soil microbial ecologists are increasingly appreciating these aspects of soil aggregation. Soil aggregates have, however, so far been neglected when it comes to evolutionary considerations (Crawford et al., 2005) and we here propose that the process of soil aggregation should be considered as an important driver of evolution in the soil microbial community.

description: Avec le phénomène de vieillissement de la population vécu actuellement, la recherche de solutions pour mieux supporter les personnes âgées sans affubler davantage la main d’œuvre se tourne vers une meilleure prévention et gestion des problèmes de santé supportée par des technologies d’information de santé. Le succès de l’adoption de ces technologies est tributaire de la perception face à l’usage de celles-ci . Cette étude a exploré les perceptions de personnes âgées à l’égard de la télésurveillance, d’appareils d’auto-suivi et de détection des chutes par l’entremise de groupes de discussion et d’entrevues. Les thèmes ressortis comprennent la familiarité avec les technologies présentées, les bénéfices, préoccupations et utilités perçus à leur usage, les conseils et améliorations souhaitées et la volonté d’usage des appareils. Les participants connaissaient peu les technologies présentées, entretenaient une attitude positive à leurs égards et percevaient d’importants bénéfices à y recourir tant pour la santé que pour la tranquillité d’esprit. Toutefois, ils entretenaient certaines craintes, surtout reliées aux difficultés de certains à pouvoir utiliser ces technologies. Ils percevaient l’utilité de celles-ci dans de nombreux contextes, mais ne s’identifiaient pas au besoin d’y recourir et ne souhaitaient pas personnellement le faire à court terme, à moins d’avoir déjà utilisé celles-ci. Adapter les technologies aux diverses limitations des personnes âgées, offrir des formations à l’usage, informer davantage la population sur les technologies d’information de santé existantes et s’assurer de rendre accessible l’usage de celles-ci pourrait favoriser l’adoption des technologies par les personnes âgées. Des recherches sont nécessaires pour vérifier si ces conclusions s’appliquent à une population plus large et concernent d’autres technologies de santé pouvant supporter les personnes âgées.

Halo intruders in the Galactic bulge revealed by HST and Gaia: the globular clusters Terzan 10 and Djorgovski 1

description: The low-latitude globular clusters Terzan 10 and Djorgovski 1 are vprojected in the Galactic bulge, in a Galactic region highly affected by extinction. A discrepancy of a factor of ~2 exists in the literature in regards to the distance determination of these clusters. We revisit the colour-magnitude diagrams (CMDs) of these two globular clusters with the purpose of disentangling their distance determination ambiguity and, for the first time, of determining their orbits to identify whether or not they are part of the bulge/bar region. We use Hubble Space Telescope CMDs, with the filters F606W from ACS and F160W from WFC3 for Terzan 10, and F606W and F814W from ACS for Djorgosvski~1, and combine them with the proper motions from Gaia Date Release 2. For the orbit integrations, we employed a steady Galactic model with bar. For the first time the blue horizontal branch of these clusters is clearly resolved. We obtain reliable distances of dSun = 10.3+-1.0 kpc and 9.3+-0.5 kpc for Terzan 10, and Djorgovski 1 respectively, indicating that they are both currently located in the bulge volume. From Gaia DR 2 proper motions, together with our new distance determination and recent literature radial velocities, we are able to show that the two sample clusters have typical halo orbits that are passing by the bulge/bar region, but that they are not part of this component. For the first time, halo intruders are identified in the bulge.

description: The ubiquitous services of wireless communication networks are growing rapidly by the development of wireless communication technologies. While a user is roaming from one cell to another cell, an intelligent decision mechanism and network selection is extremely crucial to maintain the quality of service (QoS) during handover. Handover decision must be made precisely to avoid any unnecessary phenomenon like ping-pong, corner effect, call blocking, and call dropping etc. This work considered service types like voice, video, and data and their QoS requirements for handover decision using fuzzy logic in heterogeneous network environment. Service is an important factor for the users and particular service requires respective QoS. This paper provides all the cases of handover decisions between macrocell and femtocell networks considering service type. The proposed system models regarding these handover decisions using fuzzy logic considering several input parameters e.g. received signal strength indicator (RSSI), data rate, user's velocity, and interference level (signal-to-noise plus interference ratio) to make handover from femtocell to macrocell, macrocell to femtocell or femtocell to femtocell. The performance of different parameters are shown based on service type are analyzed.

description: Static solutions of the electro-gravitational field equations exhibiting a functional relationship between the electric and gravitational potentials are studied. General results for these metrics are presented which extend previous work of Majumdar. In particular, it is shown that for any solution of the field equations exhibiting such a Weyl-type relationship, there exists a relationship between the matter density, the electric field density and the charge density. It is also found that the Majumdar condition can hold for a bounded perfect fluid only if the matter pressure vanishes (that is, charged dust). By restricting to spherically symmetric distributions of charged matter, a number of exact solutions are presented in closed form which generalise the Schwarzschild interior solution. Some of these solutions exhibit functional relations between the electric and gravitational potentials different to the quadratic one of Weyl. All the non-dust solutions are well-behaved and, by matching them to the Reissner-Nordström solution, all of the constants of integration are identified in terms of the total mass, total charge and radius of the source. This is done in detail for a number of specific examples. These are also shown to satisfy the weak and strong energy conditions and many other regularity and energy conditions that may be required of any physically reasonable matter distribution.

description: Chitosan-tripolyphosphate (CS-TPP) nanoparticles containing naproxen (NPX) were dispersed in poloxamer (PL) as unique (PL407) or binary (PL407-PL403) systems. Nanoparticles presented diameter of ∼250 nm and zeta potential of ∼35 mV with drug loading and encapsulation efficiency of 98.4 ± 0.3% and 36.9 ± 0.12%, respectively. NPX-CS-TPP shifted the sol-gel transition and micellization temperatures. PL407-PL403 systems presented G′ > G″ compared to PL407. SAXS patterns revealed transitions from lamellar to hexagonal phase organizations with low drug release rates, in the presence of CS-TPP nanoparticles. NPX-CS-TPP-PL407 induced lower cytotoxicity compared to PL407-PL403 in fibroblasts and osteoblasts, making them promising systems for intra-articular delivery.
