description: We study the chemical properties of the stellar populations in eight simulations of the formation of Milky-Way mass galaxies in a LCDM Universe. Our simulations include metal-dependent cooling and an explicitly multiphase treatment of the effects on the gas of cooling, enrichment and supernova feedback. We search for correlations between formation history and chemical abundance patterns. Differing contributions to spheroids and discs from in situ star formation and from accreted populations are reflected in differing chemical properties. Discs have younger stellar populations, with most stars forming in situ and with low alpha-enhancement from gas which never participated in a galactic outflow. Up to 15 per cent of disc stars can come from accreted satellites. These tend to be alpha-enhanced, older and to have larger velocity dispersions than the in situ population. Inner spheroids have old, metal-rich and alpha-enhanced stars which formed primarily in situ, more than 40 per cent from material recycled through earlier galactic winds. Few accreted stars are found in the inner spheroid unless a major merger occurred recently. Such stars are older, more metal-poor and more alpha-enhanced than the in situ population. Stellar haloes tend to have low metallicity and high alpha-enhancement. The outer haloes are made primarily of accreted stars. Their mean metallicity and alpha-enhancement reflect the masses of the disrupted satellites where they formed: more massive satellites typically have higher [Fe/H] and lower [alpha/Fe]. Surviving satellites have distinctive chemical patterns which reflect their extended, bursty star formation histories. These produce lower alpha-enhancement at given metallicity than in the main galaxy, in agreement with observed trends in the Milky Way.

description: We incorporate our experimentally derived thermal rate coefficients for C + ${{\rm{H}}}_{3}^{+}$ forming CH+ and CH2 + into a commonly used astrochemical model. We find that the Arrhenius–Kooij equation typically used in chemical models does not accurately fit our data and instead we use a more versatile fitting formula. At a temperature of 10 K and a density of 104 cm−3, we find no significant differences in the predicted chemical abundances, but at higher temperatures of 50, 100, and 300 K we find up to factor of 2 changes. In addition, we find that the relatively small error on our thermal rate coefficients, ~15%, significantly reduces the uncertainties on the predicted abundances compared to those obtained using the currently implemented Langevin rate coefficient with its estimated factor of 2 uncertainty.

description: Microcystins produced during harmful cyanobacterial blooms are a public health concern. Although patterns are emerging, the environmental cues that stimulate production of microcystin remain confusing, hindering our ability to predict fluctuations in bloom toxicity. In earlier work, growth at cool temperatures relative to optimum (18°C vs. 26°C) was confirmed to increase microcystin quota in batch cultures of Microcystis aeruginosa NIES-843. Here, we tested this response in M. aeruginosa PCC 7806 using continuous cultures to examine temporal dynamics and using RNA-sequencing to investigate the physiological nature of the response. A temperature reduction from 26 to 19°C increased microcystin quota ∼2-fold, from an average of ∼464 ag μm–3 cell volume to ∼891 ag μm–3 over a 7–9 d period. Reverting the temperature to 26°C returned the cellular microcystin quota to ∼489 ag μm–3. Long periods (31–42 d) at 19°C did not increase or decrease microcystin quota beyond that observed at 7–9 d. Nitrogen concentration had little effect on the overall response. RNA sequencing indicated that the decrease in temperature to 19°C induced a classic cold-stress response in M. aeruginosa PCC 7806, but this operated on a different timescale than the increased microcystin production. Microcystin quota showed a strong 48- to 72-h time-lag correlation to mcy gene expression, but no correlation to concurrent mcy expression. This work confirms an effect of temperature on microcystin quota and extends our understanding of the physiological nature of the response.

description: Radiation-induced ratchet electric currents have been studied theoretically in graphene with a periodic noncentrosymmetric lateral potential. The ratchet current generated under normal incidence is shown to consist of two contributions, one of them being polarization-independent and proportional to the energy relaxation time, and another controlled solely by elastic scattering processes and sensitive to both the linear and circular polarization of radiation. Two realistic mechanisms of electron scattering in graphene are considered. For short-range defects, the ratchet current is helicity-dependent but independent of the direction of linear polarization. For the Coulomb impurity scattering, the ratchet current is forbidden for the radiation linearly polarized in the plane perpendicular to the lateral-potential modulation direction. For comparison, the ratchet currents in a quantum well with a lateral superlattice are calculated at low temperatures with allowance for the dependence of the momentum relaxation time on the electron energy.

Inferring the Coronal Density Irregularity from EUV Spectra

description: Understanding the density structure of the solar corona is important for modeling both coronal heating and the solar wind. Direct measurements are difficult because of line-of-sight integration and possible unresolved structures. We present a new method for quantifying such structures using density-sensitive extreme ultraviolet line intensities to derive a density irregularity parameter, a relative measure of the amount of structure along the line of sight. We also present a simple model to relate the inferred irregularities to physical quantities, such as the filling factor and density contrast. For quiet-Sun regions and interplume regions of coronal holes, we find a density contrast of at least a factor of 3–10 and corresponding filling factors of about 10%–20%. Our results are in rough agreement with other estimates of the density structures in these regions. The irregularity diagnostic provides a useful relative measure of unresolved structure in various regions of the corona.

description: We present the first ultraviolet spectrum of the peculiar, magnetic Of?p star HD 108 obtained in its spectroscopic low state. The new data, obtained with the Space Telescope Imaging Spectrograph (STIS) on the Hubble Space Telescope, reveal significant changes compared to IUE spectra obtained in the high state: N V 1240, Si IV 1400, and C IV 1550 present weaker P-Cygni profiles (less absorption) in the new data, while N IV 1718 absorption is deeper, without the clear wind signature evident in the high state. Such changes contrast with those found in other magnetic massive stars, where more absorption is observed in the resonance doublets when the sightline is close to the plane of the magnetic equator. The new data show also that the photospheric Fe IV forest, at 1600--1700 angstroms, has strengthened compared to previous observations. The ultraviolet variability is large compared to that found in typical, non-magnetic O stars, but moderate when compared to the high-/low-state changes reported in the optical spectrum of HD 108 over several decades. We use non-LTE expanding-atmosphere models to analyze the new STIS observations. Overall, the results are in accord with a scenario in which the optical variability is mainly produced by magnetically constrained gas, close to the photosphere. The relatively modest changes found in the main ultraviolet wind lines suggest that the stellar wind is not substantially variable on a global scale. Nonetheless, multidimensional radiative-transfer models may be needed to understand some of the phenomena observed.

description: The Instream Flow Incremental Method (IFIM) is a logical guide to the analysis of various issues related to developing an environmental (instream) flow policy that incorporates multiple or variable flow rules to meet the needs of the aquatic ecosystem while considering habitat-flow relationships, timing of flow events, institutional arrangements, and water supply and water allocation. Models of the IFIM include the Physical Habitat Simulation System (PHABSIM), Time Series Analysis Library (TSLIB), two temperature models: Stream Network Temperature Model (SNTEMP) and the Stream Segment Temperature Model (SSTEMP), SALMOD, and the Legal Institutional Analysis Model (LIAM). The various models are designed to give the user information required to select environmental flow needs. The models do not calculate an environmental flow need - selecting an environmental flow need is the responsibility of the user. PHABSIM is a set of programs designed to predict microhabitat conditions in rivers as a function of streamflow and the relative suitability of those microhabitat conditions to aquatic life. TSLIB programs provide data entry, analysis, and display of daily or monthly flow or habitat values. Some programs are useful for integrating microhabitat and macrohabitat, and some are of value in the analysis of water operations systems. SNTEMP predicts the water temperature in streams and rivers from data describing the stream's geometry, meteorology, and hydrology. It handles a dendritic network of streams through time and space. SSTEMP is a scaled down version of SNTEMP suitable for single (to a few) reaches and single (to a few) time periods. SALMOD is a computer model that simulates the dynamics of freshwater salmonid populations. Developed and used for the Trinity River, California, Chinook salmon evaluation, SALMOD has wide applicability for freshwater habitat-limited salmonid populations. LIAM was designed to accomplish three goals: (1) plan for participation in a negotiation, (2) predict organizational behavior, and (3) examine likely negotiation strategies.

In the temperature range where W 19 + is expected to form in a collisionally ionized plasma, the experimentally derived recombination rate coefficient deviates by up to a factor of about 20 from the theoretical rate coefficient obtained from the Atomic Data and Analysis Structure database.

description: We discuss the many-body physics of an ensemble of Rydberg dressed atoms with van der Waals dipole-dipole interactions in a one-dimensional lattice. Using a strong coupling expansion and numerical density-matrix renormalisation group simulations, we calculate the many-body phase diagram. A devil's staircase structure emerges with Mott-insulating phases at any rational filling fraction. Closed analytic expressions are given for the phase boundaries in second order of the tunnelling amplitude and shown to agree very well with the numerical results. The transition point where the incompressible phases melt due to the kinetic energy term depends strongly on the denominator of the filling fraction and varies over many orders of magnitude between different phases.

description: The scattering of two Dashen-Hasslacher-Neveu (DHN) baryons in the large N Gross-Neveu model is solved exactly using the relativistic, time-dependent Hartree-Fock approach. Unlike the special case of kink-antikink scattering, the scattering of DHN baryons is sensitive to the back-reaction of the fermions bound inside the baryons. Correspondingly the solution is much more complicated than the kink-antikink scattering solutions, which can be expressed in terms of sinh-Gordon solitons. Nevertheless, we present a simple ansatz form that gives closed analytic expressions for both the space-time dependent mean fields and the Dirac spinors for all continuum and bound states. The solution can also be applied to the scattering of polarons and solitons in conducting polymers.

description: We have measured electron impact ionization (EII) for Fe8+ forming Fe9+ from below the ionization threshold to 1200 eV. These measurements were carried out at the TSR heavy ion storage ring. The objective of using a storage ring is to store the ion beam initially so that metastable levels decay, thereby allowing for measurements on a well-defined ground-level ion beam. In this case, however, some metastable levels were too long lived to be removed. We discuss several methods for quantifying the metastable fraction, which we estimate to be ∼30%– 40%. Although metastables remain problematic, the present storage ring work improves upon other experimental geometries by limiting the metastable contamination to only a few long-lived excited levels. We discuss some future prospects for obtaining improved measurements of Fe8+ and other ions with long-lived metastable levels.

description: We report measured rate coefficients for electron–ion recombination of Si10+ forming Si9+ and of Si9+ forming Si8+, respectively. The measurements were performed using the electron–ion merged-beams technique at a heavy-ion storage ring. Electron–ion collision energies ranged from 0 to 50 eV for Si9+ and from 0 to 2000 eV for Si10+, thus, extending previous measurements for Si10+ (Orban et al 2010 Astrophys. J. 721 1603) to much higher energies. Experimentally derived rate coefficients for the recombination of Si9+ and Si10+ ions in a plasma are presented along with simple parameterizations. These rate coefficients are useful for the modeling of the charge balance of silicon in photoionized plasmas (Si9+ and Si10+) and in collisionally ionized plasmas (Si10+ only). In the corresponding temperature ranges, the experimentally derived rate coefficients agree with the latest corresponding theoretical results within the experimental uncertainties.

description: Inner-shell ionization of a 1s electron by either photons or electrons is important for X-ray photoionized objects such as active galactic nuclei and electron-ionized sources such as supernova remnants. Modeling and interpreting observations of such objects requires accurate predictions for the charge state distribution (CSD), which results as the 1s-hole system stabilizes. Due to the complexity of the complete stabilization process, few modern calculations exist and the community currently relies on 40-year-old atomic data. Here, we present a combined experimental and theoretical study for inner-shell photoionization of neutral atomic nitrogen for photon energies of 403–475 eV. Results are reported for the total ion yield cross section, for the branching ratios for formation of N + , N2+, and N3+, and for the average charge state. We find significant differences when comparing to the data currently available to the astrophysics community. For example, while the branching ratio to N2+ is somewhat reduced, that for N + is greatly increased, and that to N3+, which was predicted to be zero, grows to »10% at the higher photon energies studied. This work demonstrates some of the shortcomings in the theoretical CSD data base for inner-shell ionization and points the way for the improvements needed to more reliably model the role of innershell ionization of cosmic plasmas.

description: Understanding the effects of climate change on the distribution of river flow has been a longstanding objective. This paper investigates the possible effects of such climatic changes on streamflow of the Arkansas River in Colorado. Changes in monthly flow regimes were projected and aggregated to a decadal time scale using two future climate scenarios. The streamflow projections were derived from a relationship between streamflow and accumulated snow and temperature in the study re-gion mapped by a neural network developed for this purpose. April-September streamflow projections for the Arkansas River were analyzed for any changes. Results indicate an increase in the river flow, and in most cases the increases coincided with increased precipitation and temperature within the river basin. The historical peak flow shifted to from June to April. Frequency analyses of flow show that any flow in the months of April-July would be exceeded more frequently in the future. The percent of exceedance varies between the months. It is high for April-July; very low for August and almost negligible for September.

description: Holonomy corrections to scalar perturbations are investigated in the loop quantum cosmology framework. Due to the effective approach, modifications of the algebra of constraints generically lead to anomalies. In order to remove those anomalies, counter-terms are introduced. We find a way to explicitly fulfill the conditions for anomaly freedom and we give explicit expressions for the counter-terms. Surprisingly, the "new quantization scheme" naturally arises in this procedure. The gauge invariant variables are found and equations of motion for the anomaly-free scalar perturbations are derived. Finally, some cosmological consequences are discussed qualitatively.

La traducción como acto creativo en la prosa de Jorge Luis Borges
Creators: name: Goundareva, Irina
Publisher: name: University of British Columbia

description: In this thesis we examine the conception of translation in the work of Jorge Luis Borges. Our hypothesis maintains that Borges approaches translation as a creative act and as a paradox, which stands for translation as an impossible and at the same time inevitable act of transference from one culture and its language into another linguistic and cultural system. Some of the questions that guide this project are: according to Borges 1) What is the difference between author and translator? 2) Does translation require linguistic, cultural and philosophical competence, or one is more important than the other? 3) What is necessary to be a good translator? 4) Is it necessary to be a writer to become a literary translator? 5) What is the relationship between a translated text and a source text? 6) Is the “original” only a version? 7) Is there an implicit hierarchy between the translated text and the original? From here we suggest that Borges, without establishing his own theory of translation, problematizes the idea of the “original” and the requirement of linguistic and cultural competence for a translator. According to Borges, only through the freedom of creativity, translation can get closer to the values of a text that belongs to another language, culture or time. For him, translation is only possible if it becomes rewriting ad infinitum of a text that is not necessarily the “original”.

description: We have measured the reaction of O H + 3 + forming OH+ and H2O . + This is believed to be one of the key gasphase astrochemical processes initiating the formation of water molecules in dense molecular clouds. For this work, we have used a novel merged fast-beams apparatus that overlaps a beam of H3 + onto a beam of ground-term neutral O. Here, we present cross-section data for forming OH+ and H2O+ at relative energies from ≈3.5 meV to ≈15.5 and 0.13 eV, respectively. Measurements were performed for statistically populated O PJ 3( ) in the ground term reacting with hot H3 + (with an internal temperature of ∼2500–3000 K). From these data, we have derived rate coefficients for translational temperatures from ≈27 K to ∼105 K for the formation of OH+ and ∼103 K for the formation of H2O+. In order to convert these results to a thermal rate coefficient suitable for astrochemistry, we have added the results together for both exit channels and scaled the summed data on statistically populated oxygen to thermally populated oxygen. For this we have used theory as a guide, thereby accounting for the temperature dependence of the O fine-structure levels. Our results are in good agreement with two independent flowing afterglow measurements at a temperature of ≈300 K, and with a corresponding level of H3 + internal excitation. This good agreement suggests that the internal excitation of the H3 + does not play a significant role in this reaction. The Langevin rate coefficient is in reasonable agreement with the experimental results at 10 K but a factor of ∼2 larger at 300 K. The two published classical trajectory studies using quantum-mechanical potential energy surfaces lie a factor of ∼1.5 above our experimental results over this 10–300 K range.

description: Ulasan tempat makan pada situs daring seringkali memberikan skor yang tidak sesuai dengan makna pada ulasan. Ulasan dapat berskor rendah namun ulasan mengandung makna positif dan ulasan berskor tinggi dapat mengandung makna yang negatif. Berbagai upaya klasifikasi sentimen ulasan dengan menggunakan analisis sentimen telah dilakukan pada banyak penelitian. Namun analisis sentimen dengan hanya mengandalkan pendekatan supervised learning memberikan hasil salah satu kelas cenderung lebih sering muncul sehingga berakibat pada menurunnya kinerja pengklasifikasi. Dalam makalah ini, pendekatan Improved Naive Bayes yaitu Naive Bayes dengan fitur unigram dan bigram dipadukan dengan pendekatan menggunakan lexicon diusulkan untuk meningkatkan kinerja pengklasifikasi. Fitur diperoleh dengan mengekstrak pola POS TAG yang mengandung kata atau frasa yang mengekspresikan emosi yang relevan dengan ulasan tempat makan. Lexicon dibangun secara manual dengan mengumpulkan kata dan frasa unigram dan bigram yang menunjukan emosi yang relevan diungkapkan pada ulasan tempat makan. Pengklasifikasi dengan menggunakan Improved Naive Bayes menunjuakan kinerja yang lebih baik dibandingkan pengklasifikasi menggunakan Naive Bayes. Improved Naive Bayes memperoleh skor precision 80%, recall 77%, dan F1 76%. Sedangkan Naive Bayes memperoleh skor precision 68%, recall 60%, dan F1 56%.

description: We demonstrate the use of high power diode laser stacks to photodetach fast hydrogen and carbon anions and produce ground term neutral atomic beams. We achieve photodetachment efficiencies of ∼7.4% for H− at a beam energy of 10 keV and ∼3.7% for C− at 28 keV. The diode laser systems used here operate at 975 nm and 808 nm, respectively, and provide high continuous power levels of up to 2 kW, without the need of additional enhancements like optical cavities. The alignment of the beams is straightforward and operation at constant power levels is very stable, while maintenance is minimal. We present a dedicated photodetachment setup that is suitable to efficiently neutralize the majority of stable negative ions in the periodic table.

description: We consider pairs of non-interacting quantum particles transmitted through a disordered medium, with emphasis on the role of their quantum statistics. It is shown that particle-number correlations measured in transmission are strikingly sensitive to the quantum nature of the particles when they undergo Anderson localisation, due to bosonic bunching and fermionic anti-bunching in the scattering channels of the medium. The case of distinguishable particles is also discussed.

description: A strongly-interacting fermion chain with supersymmetry on the lattice and open boundary conditions is analysed. The local coupling constants of the model are staggered, and the properties of the ground states as a function of the staggering parameter are examined. In particular, a connection between certain ground-state components and solutions of non-linear recursion relations associated with the Painlevé VI equation is conjectured. Moreover, various local occupation probabilities in the ground state have the so-called scale-free property, and allow for an exact resummation in the limit of infinite system size.

description: We have measured electron impact ionization for Fe7+ from the ionization threshold up to 1200 eV. The measurements were performed using the TSR heavy ion storage ring. The ions were stored long enough prior to measurements to remove most metastables, resulting in a beam of 94% ground-level ions. Comparing with the previously recommended atomic data, we find that the Arnaud & Raymond cross section is up to about 40% larger than our measurement, with the largest discrepancies below about 400 eV. The cross section of Dere agrees to within 10%, which is about the magnitude of the experimental uncertainties. The remaining discrepancies between our measurement and the Dere calculations are likely due to shortcomings in the theoretical treatment of the excitation-autoionization contribution.
