Notes
The current circumscription of Begonia sect. Knesebeckia is a “taxonomic dustbin” composed of mostly Central American and Andean caulescent species with four tepals on the staminate flower, five tepals on the pistillate flower, and divided placentae. Moonlight et al. (2018) demonstrated that the section is polyphyletic with at least four clades, a central American clade including the type species and three Andean clades. Peruvian species fall into all three Andean clades, and we recognise one of these as Begonia sect. Apteron above. The two other clades are found in Peru but, as no morphological characters have yet been found to identify these clades, we do not recognise them formally herein. Rather, we group species into two informal groups, the acerifolia and the maynensis groups. While perhaps not monophyletic, these groups are easily recognisable and of use for identifying species.
The current circumscription of Begonia sect. Knesebeckia includes fifteen species in Peru, of which seven are in the acerifolia group and four are in the maynensis group. We describe one new species, provide the first record of a second, and provide one new synonym within this section. Five species are endemic to Peru.

On the dynamics of Einstein's equations in the Ashtekar formulation

description: We study the dynamics of Einstein's equations in Ashtekar's variables from the point of view of the theory of hyperbolic systems of evolution equations. We extend previous results and show that by a suitable modification of the Hamiltonian vector flow outside the sub-manifold of real and constrained solutions, a symmetric hyperbolic system is obtained for any fixed choice of lapse-shift pair, without assuming the solution to be a priori real. We notice that the evolution system is block diagonal in the pair $(σ^a,A_b)$, and provide explicit and very simple formulae for the eigenvector-eigenvalue pairs in terms of an orthonormal tetrad with one of its components pointing along the propagation direction. We also analyze the constraint equations and find that when viewed as functions of the extended phase space they form a symmetric hyperbolic system on their own. We also provide simple formulae for its eigenvectors-eigenvalues pairs.

description: In this paper we discuss the implementation of an ONOS application that leverages Energy-Efficient Ethernet links between a pair of switches and shares incoming traffic among the link in the way that minimizes overall energy usage. As the straightforward solution can result in excessive traffic delay, we provide two alternative solutions to meet the demands of real time traffic arriving to the link aggregate. Experimental results show that our final application can keep low energy usage while meeting the demands of time-sensitive traffic, as long as the latter does not represent an excessive share of traffic demand.

A two-dimensional (2D) Fermi surfaces are characterized by four parameters. Several conditions for the coherence and enhancement of currents are discussed.

Constrained randomization of time series data

subject: FOS: Physical sciences

description: A new method is introduced to create artificial time sequences that fulfil given constraints but are random otherwise. Constraints are usually derived from a measured signal for which surrogate data are to be generated. They are fulfilled by minimizing a suitable cost function using simulated annealing. A wide variety of structures can be imposed on the surrogate series, including multivariate, nonlinear, and nonstationary properties. When the linear correlation structure is to be preserved, the new approach avoids certain artifacts generated by Fourier-based randomization schemes.

description: We investigate the possibility of statistical explanation of the black hole entropy by counting quasi-bounded modes of thermal fluctuation in two dimensional black hole spacetime. The black hole concerned is quantum in the sense that it is in thermal equilibrium with its Hawking radiation. It is shown that the fluctuation around such a black hole obeys a wave equation with a potential whose peaks are located near the black hole and which is caused by quantum effect. We can construct models in which the potential in the above sense has several positive peaks and there are quai-bounded modes confined between these peaks. This suggests that these modes contribute to the black hole entropy. However it is shown that the entropy associated with these modes dose not obey the ordinary area law. Therefore we can call these modes as an additional thermal hair of the quantum black hole.

description: Effective crisis communication response through using the proper strategies is critical to cope with crises and to protect the reputation and existence of the involved parties. Usually, aviation accidents receive great attention from the media and the public. Malaysia Airlines Flight 17 (MH17) which was shot down over eastern Ukraine on 17 July 2014 during its scheduled flight from Amsterdam to Kuala Lumpur
received global attention. This attention was due to the involvement of several countries either at the level
of the countries of victims or the countries accused of the attack. Image repair theory proposed by William Benoit, the widely used in crisis communication response was implemented in this study. The Russian response to the international accusation, especially from the Western world on supporting the attackers of MH17 has been examined in this study. This study implemented both quantitative and
qualitative content analysis to achieve its aims. A total of 306 news stories from the online New Straits Times newspaper Website from the years 2014 to 2019 were analysed. A total of 191 strategies were included in 123 news stories since some stories combined more than a strategy. Out of 191 strategies, 43.5% were simple denial, followed by shift the blame and attack accuser with 35.1% and 21.5% respectively. The results revealed that the image repair effort by Russia was effective and successful.

description: Infrared OH lines at 1.5 - 1.7 um in the H band were obtained with the NIRSPEC high-resolution spectrograph at the 10m Keck Telescope for a sample of seven metal-poor stars. Detailed analyses have been carried out, based on optical high-resolution data obtained with the FEROS spectrograph at ESO. Stellar parameters were derived by adopting infrared flux method effective temperatures, trigonometric and/or evolutionary gravities and metallicities from FeII lines. We obtain that the sample stars with metallicities [Fe/H] < -2.2 show a mean oxygen abundance [O/Fe] ~ 0.54, for a solar oxygen abundance of epsilon(O) = 8.87, or [O/Fe] ~ 0.64 if epsilon(O) = 8.77 is assumed.

description: We consider the conductivity tensor for composite fermions in a close to half-filled Landau band in the temperature regime where the scattering off the potential and the trapped gauge field of random impurities dominates. The Boltzmann equation approach is employed to calculate the quasiclassical transport properties at finite effective magnetic field, wavevector and frequency. We present an exact solution of the kinetic equation for all parameter regimes. Our results allow a consistent description of recently observed surface acoustic wave resonances and other findings.

Discrimination power of measures for nonlinearity in a time series

Publisher: name: arXiv
Year: 1999
Subjects: subject: Chaotic Dynamics (nlin.CD)
subject: FOS: Physical sciences

description: The performance of a number of different measures of nonlinearity in a time series is compared numerically. Their power to distinguish noisy chaotic data from linear stochastic surrogates is determined by Monte Carlo simulation for a number of typical data problems. The main result is that the ratings of the different measures vary from example to example. It seems therefore preferable to use an algorithm with good overall performance, that is, higher order autocorrelations or nonlinear prediction errors.

description: A modelling investigation was conducted into optimizing the number of sprays and inter-spray interval to reduce an insect population to a low level, for example, prior to pheromone trapping or the release of sterile males. The model population was age-structured and density-dependent. If spray mortality is 100% for each spray, then the ideal spraying schedule is easily determined from the durations of the various life stages. For spray mortality of less than 100%, a simulation was used to determine optimal spraying schedules. Relative length of the larval period, fertility rate and age to first oviposition were found to be the most important biotic parameters for this determination. Their importance is magnified as spray mortality decreases. The stage targeted by sprays and the percent mortality caused by each spray are also important in determining the required number of sprays. Using medfly (Ceratitis capitata Wiedmann) biotic parameters as an example when the spray targets adults, it appeared that neither the stage at which density-dependent mortality takes effect, nor the form of the adult survivorship curve are important in determining the optimal spray schedule.

description: A compilation of photometric time-series data of NGC 4147 spanning 58 years, enabled to study the secular behaviour of the pulsation period in the population of RR Lyrae stars in the cluster. The traditional O-C diagram approach was employed. Three stars display a significant period decrease and two a comparable period increase. Nevertheless, the median value of the whole sample is nearly zero, which seems consistent with theoretical expectations. The limitations of empirical determinations of secular period changes in globular clusters to corroborate evolutionary theoretical predictions are discussed.

description: The Schur functions play a crucial role in the modern description of HOMFLY polynomials for knots and of topological vertices in DIM-based network theories, which could merge into a unified theory still to be developed. The Macdonald functions do the same for hyperpolynomials and refined vertices, but merging appears to be more problematic. For a detailed study of this problem, more knowledge is needed about the Macdonald polynomials than is usually available. As a preparation for the discussion of the knot/vertices relation, we summarize the relevant facts and open problems about the Macdonald and, more generally, Kerov functions. Like Macdonald polynomials, they are triangular combinations of Schur functions, but orthogonal in a more general scalar product. We explain that the parameters of the measure can be considered as a set of new time variables, and the Kerov functions are actually expressed through the Schur functions of these variables as well. Despite they provide an infinite-parametric extension of the Schur and Macdonald polynomials, the Kerov functions, and even the skew Kerov functions continue to satisfy the most important relations, like Cauchy summation formula, the transposition identity for reflection of the Young diagram and expression of the skew functions through the generalized Littlewood-Richardson structure constants. Since {\it these} are the properties important in most applications, one can expect that the Kerov extension exists for most of them, from the superintegrable matrix and tensor models to knot theory.

description: Psoriasis is a chronic immune mediated disorder of the skin. There is growing evidence that the Src family tyrosine kinases (SFK) are highly upregulated in psoriasis. The SFK are the key components of the signaling pathways triggering cell growth and differentiation in addition to the immune cascades. In the current work, the interactions between SFK and selective phyto-compounds were studied using molecular docking approach. Based on the results of docking and binding energy calculations quercetin was identified as potential lead compound. To get a deeper insight into the binding of quercetin with the SFK, a combined molecular dynamics and binding free energy calculations were performed. The binding of quercetin disrupted the intra-molecular contacts making the SFK compact except Src kinase. The MM/PBSA free energy decomposition analysis highlighted the significance of hydrophobic and polar residues which are involved in the binding of quercetin. An experimental validation was carried out against the activated forms of Fyn, Lyn and Src kinases, the top three proteins which showed high preference for quercetin. The flow cytometry analysis showed that the expression levels of Fyn, Lyn and Src kinases were dramatically increased in HaCaT cells. However, the treatment of quercetin at the concentration of 51.65 µM for 24 h markedly decreased their expression in HaCaT cells. Besides, similar results were also observed when the HaCaT cells were treated with the kinase inhibitor Ponitinib (1.43 µM) for 24 h. Communicated by Ramaswamy H. Sarma

description: We report on a strong nonlinear behavior of the photogalvanics and photoconductivity under excitation of HgTe quantum wells (QWs) by intense terahertz (THz) radiation. The increasing radiation intensity causes an inversion of the sign of the photocurrent and transition to its superlinear dependence on the intensity. The photoconductivity also shows a superlinear raise with the intensity. We show that the observed photoresponse nonlinearities are caused by the band-to-band \emph{light} impact ionization under conditions of a photon energy less than the forbidden gap. The signature of this kind of impact ionization is that the angular radiation frequency $ω=2πf$ is much higher than the reciprocal momentum relaxation time. Thus, the impact ionization takes place solely because of collisions in the presence of a high-frequency electric field. The effect has been measured on narrow HgTe/CdTe QWs of 5.7\,nm width; the nonlinearity is detected for linearly and circularly polarized THz radiation with different frequencies ranging from $f=0.6$ to 1.07\,THz and intensities up to hundreds of kW/cm$^2$. We demonstrate that the probability of the impact ionization is proportional to the exponential function, $\exp(-E_0^2/E^2)$, of the radiation electric field amplitude $E$ and the characteristic field parameter $E_0$. The effect is observable in a wide temperature range from 4.2 to 90\,K, with the characteristic field increasing with rising temperature.

description: A family of effective actions in Hamiltonian form is derived for a self-gravitating sphere of isotropic homogeneous dust. Starting from the Einstein-Hilbert action for barotropic perfect fluids and making use of the symmetry and equation of state of the matter distribution we obtain reduced actions for two canonical variables, namely the radius of the sphere and its ADM energy, the latter being conserved along trajectories of the former. These actions differ by the value of the (conserved) geodesic energy of the radius of the sphere which defines (disconnected) classes of solutions in correspondence to the inner geometry and proper volume of the sphere. Each class is thus treated as one constrained dynamical system and the union of all classes covers the full phase space of the model. Generalization to the (inhomogeneous) Tolman model is shown to be straightforward. Quantization is also discussed.

A distinctive feature of this paper is that the problem is considered in arbitrary dimensions, and the electrical conductivity is allowed to vanish above a threshold temperature value. The existence of a steady state is proved, an objective functional is introduced, the existence of the optimal control is proved, and the optimality system is derived.

description: Presentation on proposed changes to the  element. Abstract: Events are a feature of life in space and time and hence are frequently encountered in witnesses of the human culture. Coming from diverse backgrounds within the TEI based realm of scholarly editing, the authors identified a common practice in digital editions for encoding events: dateable events are commonly recorded and marked up using e.g. simple `date/@when*` structures. To date, there is no easy single solution to model events that include basic other event features, mainly referring back to the questions of `what` happened `when` and with `whom`/`what` as subjects and objects of any given event. There are numerous examples from generically and disciplinarily varying editions where a unified way of describing events could provide added value. Our showcase examples feature material as diverse as a) a medieval itinerary and medieval calendars, b) an Austrian author’s diary from the 1950s and c) a corpus of governmental minutes from the Habsburg empire, d) 16th century political correspondence. We will propose a common strategy on how to encode events in a way that can be easily parsed and extracted from TEI source files. After careful consideration, we propose minor changes to the `event` and `listEvent` elements. To allow for multiple levels of reporting on events, we will discuss a nested and typed way of distinguishing between describing and described events. Merging data on historical events from various sources will provide for a closer linking of text editions. It will also provide data for an enriched historical background by linking events across editions. We hope to enable the TEI community to generalize what has lately been successfully adopted for correspondences under the correspSearch label – including a web service –, while staying in line with the generic norms and the specific needs that arise from other types of sources. -- Presentation text is contained in the .pptx version as speakers notes.

description: The resistance to the endocrine therapy of breast cancer leads to the emergence of new class of drugs that downregulates the estrogen receptor action known as selective estrogen receptor downregulators (SERDs). The first approved SERD is fluvestrant; after this, there are several downregulators evolved and are in clinical trials, in which the brilanestrant (BRI) molecule shows nM range of binding affinity and efficacy. In the present study, to understand the binding nature of BRI molecule in the active site of ERα, the molecular docking analysis has been performed. Further, the QM/MM calculations were performed for the BRI–ERα complex to analyze the charge density distribution of intermolecular interactions. The molecular dynamics (MD) simulation was employed to understand the stability and binding mechanism of BRI molecule through root-mean-square deviation (RMSD), root-mean-square fluctuation (RMSF) and binding free energy calculations. From the MD simulation trajectory analysis, the alterations of Helix12 conformation and the key residue (Lys529), which is responsible for the ERα downregulation, have been identified. Further, the interaction between the H3 and H12 regions was identified for the antagonism of BRI molecule. The current study led us to understand the binding mechanism, antagonism and downregulation of BRI molecule, and this knowledge is essential to design novel SERDs for the treatment of endocrine-resistant positive breast cancer.

description: We consider the problem of bosonizing supersymmetric quantum mechanics (SSQM) and some of its variants, i.e., of realizing them in terms of only boson-like operators without fermion-like ones. In the SSQM case, this is realized in terms of the generators of the Calogero-Vasiliev algebra (also termed deformed Heisenberg algebra with reflection). In that of the SSQM variants, this is done by considering generalizations of the latter algebra, namely the $C_λ$-extended oscillator algebras, where $C_λ$ is the cyclic group of order~$λ$.

description: {We aim to demonstrate the effect of atmospheric inhomogeneities on the emergent specific intensity and radiation flux of a spectral line radiation.} {We self-consistently solve the NLTE problem for a two-level atom in a 3D atmosphere using the Cartesian grid. For that purpose, we use the 3D radiative transfer code PORTA. By examining simple examples, we study cases where the temperature inhomogeneities in the atmosphere models lead to the modification of the emergent radiation.} {We show that specific temperature inhomogeneities in the model atmospheres influence the emerging radiation, and that interpretation of the stellar spectra based on a plane-parallel atmosphere models can lead to erroneous conclusions about the atmospheric structure.}

Metallicity Evolution of Damped Lyman-Alpha Galaxies

Year: 2002

subject: FOS: Physical sciences

description: We have reanalyzed the existing data on Zinc abundances in damped Ly-alpha (DLA) absorbers to investigate whether their mean metallicity evolves with time. Most models of cosmic chemical evolution predict that the mass- weighted mean interstellar metallicity of galaxies should rise with time from a low value ~ 1/30 solar at z ~ 3 to a nearly solar value at z ~ 0. However, several previous analyses have suggested that there is little or no evolution in the global metallicity of DLAs. We have used a variety of statistical techniques to quantify the global metallicity-redshift relation and its uncertainties, taking into account both measurement and sampling errors. Three new features of our analysis are: (a) an unbinned N(H I)-weighted nonlinear chi-square fit to an exponential relation; (b) survival analysis to treat the large number of limits in the existing data; and (c) a comparison of the data with several models of cosmic chemical evolution based on an unbinned N(H I)-weighted chi-square. We find that a wider range of evolutionary rates is allowed by the present data than claimed in previous studies. The slope of the exponential fit to the N(H I)-weighted mean Zn metallicity vs. redshift relation is -0.20 plus minus 0.11 counting limits as detections and -0.27 plus minus 0.12 counting limits as zeros. Similar results are also obtained if the data are binned in redshift, and if survival analysis is used. These slopes are marginally consistent with no evolution, but are also consistent with the rates predicted by several models of cosmic chemical evolution. Finally, we outline some future measurements necessary to improve the statistics of the global metallicity-redshift relation.

Subjects: subject: Chaotic Dynamics (nlin.CD)
subject: FOS: Physical sciences

description: We propose an informal test for stationarity in a time series which checks for the compatibility of nonlinear approximations to the dynamics made in different segments of the sequence. The segments are compared directly, rather than via statistical parameters. The approach provides detailed information about episodes with similar dynamics during the measurement period. Thus physically relevant changes in the dynamics can be followed.

description: The possibility of a (sizable) nonperturbative contribution to the charm parton distribution function (PDF) in a nucleon is investigated together with theoretical issues arising in its interpretation. Results from the global PDF analysis are presented. The separation of the universal component of the nonperturbative charm from the rest of the radiative contributions is discussed and the potential impact of a nonperturbative charm PDF on LHC scattering processes is illustrated. An estimate of nonperturbative charm magnitude in the CT14 and CT14HERA2 global QCD analyses at the next-to-next-to leading order (NNLO) in the QCD coupling strength is given by including the latest experimental data from HERA and the Large Hadron Collider (LHC). A comparison between different models of intrinsic charm is shown and prospects for standard candle observables at the LHC are illustrated.

description: During the last few years, there has been plenty of research for reducing energy consumption in telecommunication infrastructure. However, many of the proposals remain unim-plemented due to the lack of flexibility in legacy networks. In this paper we demonstrate how the software defined networking (SDN) capabilities of current networking equipment can be used to implement some of these energy saving algorithms. In particular, we developed an ONOS application to realize an energy-aware traffic scheduler to a bundle link made up of Energy Efficient Ethernet (EEE) links between two SDN switches. We show how our application is able to dynamically adapt to the traffic characteristics and save energy by concentrating the traffic on as few ports as possible. This way, unused ports remain in Low Power Idle (LPI) state most of the time, saving energy.

description: The low frequency quantum transport properties of a three-probe mesoscopic conductor are studied using Büttiker's AC transport formalism. The static transmission coefficients and emittance matrix of the system were computed by explicitly evaluating the various partial density of states (PDOS). We have investigated the finite size effect of the scattering volume on the global PDOS. By increasing the scattering volume we observed a gradual improvement in the agreement of the total DOS as computed externally or locally. Our numerical data permits a particular fitting form of the finite size effect.

description: We show that there is a consistent polynomial quantization of the coordinate ring of a basic nilpotent coadjoint orbit of a semisimple Lie group. We also show, at least in the case of a nilpotent orbit in sl(2,R)*, that any such quantization is essentially trivial. Furthermore, we prove that the coordinate ring of a basic semisimple orbit in sl(2,R)* cannot be consistently polynomially quantized.
