Effect of the interaction between two species of marine diatoms on their individual copper tolerance
Creators: name: Metaxas, Anna
Publisher: name: University of British Columbia
Year: 2010

description: The importance of species interactions in studies assessing the trace metal tolerance of individual species, has been largely overlooked. Most toxicity assessments involve single-species tests. Although relevant in some cases, this approach does not incorporate the biological enviroment of an organism as a factor that might influence its survival. On the other hand, this factor is incorporated in studies at the community level. However, the latter, not examining the mechanisms that drive the interactions in the community, do not allow for prediction of the outcome after the addition of a stress inducer, such as trace metals. The purpose of this study was to examine the effect of the interaction of two species of marine diatoms (Skeletonema costatum (Cleve) Greville and Nitzschia thermalis (Ehrenberg) Auerswald) on their individual copper tolerances. The two species were grown in unialgal cultures in order to determine their copper tolerance. 5. costatum did not exhibit growth above 5 x 10⁻⁷ M (pCu = 8.46) and N. thermalis above 6 x 10⁻⁷M added total copper (pCu = 8.36). Skeletonema exhibited increased growth rate and lag phase with increasing copper concentration (and decreasing pCu). On the other hand, Nitzschia demonstrated decreased growth rate. No effect on lag phase was observed for this species. No difference between the tolerances of two strains of S. costatum was observed. Both strains demonstrated unaffected growth at 1 x 10⁻⁷M (pCu = 9.16) and no growth at 1 x 10⁻⁵ M added total copper (pCu = 7.16). Subsequently, Skeletonema costatum and Nitzschia thermalis were grown together at three copper concentrations (1 x 10⁻⁹ M, 4 x 10⁻⁷M and 5 x 10⁻⁷M added total copper). In the unialgal cultures that were used as controls, the two species grew as predicted from their tolerance tests. However, in the mixed cultures, Nitzschia was the only species that exhibited growth, regardless of the copper concentration in the medium. This inhibition of Skeletonema in the presence of the second diatom, was attributed to a toxic Nitzschia exudate. The effect of the exudate appeared to be temporary, as demonstrated by the extended lag phase and subsequent satisfactory exponential growth rate of Skeletonema. It is suggested that exponential growth rate was resumed because the exudate degrades within a period of five days (= lag phase). It is shown that the interaction between the two diatom species is more important in determining the survival of S. costatwn than its individual copper tolerance. This is not the case for N. thermalis. Such interactions would be unaccounted for in single-species toxicity tests. On the other hand, if they are known, prediction of how a community that includes these two species would respond to copper additions becomes possible.

description: We compute the magnetic susceptibility and specific heat of the spin-1/2 Heisenberg model on the kagome lattice with high-temperature expansions and exact diagonalizations. We compare the results with the experimental data on ZnCu3(OH)6Cl2 obtained by Helton et al. [Phys. Rev. Lett. 98, 107204 (2007)]. Down to k_BT/J~0.2, our calculations reproduce accurately the experimental susceptibility, with an exchange interaction J~190K and a contribution of 3.7% of weakly interacting impurity spins. The comparison between our calculations of the specific heat and the experiments indicate that the low-temperature entropy (below ~20K) is smaller in ZnCu3(OH)6Cl2 than in the kagome Heisenberg model, a likely signature of other interactions in the system.

description: Infrared dark clouds (IRDCs) are potential hosts of the elusive early phases of high-mass star formation (HMSF). Here we conduct an in-depth analysis of the fragmentation properties of a sample of 10 IRDCs, which have been highlighted as some of the best candidates to study HMSF within the Milky Way. To do so, we have obtained a set of large mosaics covering these IRDCs with ALMA at band 3 (or 3mm). These observations have a high angular resolution (~3arcsec or ~0.05pc), and high continuum and spectral line sensitivity (~0.15mJy/beam and ~0.2K per 0.1km/s channel at the N2H+(1-0) transition). From the dust continuum emission, we identify 96 cores ranging from low- to high-mass (M = 3.4 to 50.9Msun) that are gravitationally bound (alpha_vir = 0.3 to 1.3) and which would require magnetic field strengths of B = 0.3 to 1.0mG to be in virial equilibrium. We combine these results with a homogenised catalogue of literature cores to recover the hierarchical structure within these clouds over four orders of magnitude in spatial scale (0.01pc to 10pc). Using supplementary observations at an even higher angular resolution, we find that the smallest fragments (<0.02pc) within this hierarchy do not currently have the mass and/or the density required to form high-mass stars. Nonetheless, the new ALMA observations presented in this paper have facilitated the identification of 19 (6 quiescent and 13 star-forming) cores that retain >16Msun without further fragmentation. These high-mass cores contain trans-sonic non-thermal motions, are kinematically sub-virial, and require moderate magnetic field strengths for support against collapse. The identification of these potential sites of high-mass star formation represents a key step in allowing us to test the predictions from high-mass star and cluster formation theories.

description: The future laser interferometric gravitational-wave detectors sensitivity can be improved using squeezed light. In particular, recently a scheme which uses the optical field with frequency dependent squeeze factor, prepared by means of a relatively short (~30 m) amplitude filter cavity, was proposed \cite{Corbitt2004-3}. Here we consider an improved version of this scheme, which allows to further reduce the quantum noise by exploiting the quantum entanglement between the optical fields at the filter cavity two ports.

description: The 14N/15N ratio in molecules exhibits a large variation in star-forming regions, especially when measured from N2H+ isotopologues. However, there are only a few studies performed at high-angular resolution. We present the first interferometric survey of the 14N/15N ratio in N2H+ obtained with the Atacama Large Millimeter Array towards four infrared-dark clouds harbouring 3~mm continuum cores associated with different physical properties. We detect N15NH+ (1-0) in about 20-40% of the cores, depending on the host cloud. The 14N/15N values measured towards the millimeter continuum cores range from a minimum of 80 up to a maximum of 400. The spread of values is narrower than that found in any previous single-dish survey of high-mass star-forming regions, and than that obtained using the total power data only. This suggests that the 14N/15N ratio is on average higher in the diffuse gaseous envelope of the cores, and stresses the need for high-angular resolution maps to measure correctly the 14N/15N ratio in dense cores embedded in IRDCs. The average 14N/15N ratio of 210 is also lower than the interstellar value at the Galactocentric distance of the clouds (300-330), although the sensitivity of our observations does not allow us to unveil 14N/15N ratios higher than 400. No clear trend is found between the 14N/15N ratio and the core physical properties. We find only a tentative positive trend between 14N/15N and the H2 column density. However, firmer conclusions can be drawn only with higher sensitivity measurements.

description: Cell spreading is investigated at various scales in order to understand motility of living cells which is essential for a range of physiological activities in higher organisms as well as in microbes. At a microscopic scale, it has been seen that actin polymerization at the leading edge of cell membrane primarily helps the cell to spread depending upon its extra-cellular environment which influences the polymerization process via some receptors on the cell membrane. There are some interesting experimental results at macroscopic scales (cell size) where people have observed various dynamic phases in terms of spreading rate of cell area adhering to the substrate. In the present paper we develop a very simple phenomenological model to capture these dynamic apparent phases of a spreading cell without going into the microscopic details of actin polymerization.

description: We have studied the effect of annealing temperature on the statistical properties of $WO_3$ surface using atomic force microscopy techniques (AFM). We have applied both level crossing and structure function methods. Level crossing analysis indicates an optimum annealing temperature of around 400$^oC$ at which the effective area of the $WO_3$ thin film is maximum, whereas composition of the surface remains stoichiometric. The complexity of the height fluctuation of surfaces was characterized by roughness, roughness exponent and lateral size of surface features. We have found that there is a phase transition at around 400$^oC$ from one set to two sets of roughness parameters. This happens due to microstructural changes from amorphous to crystalline structure in the samples that has been already found experimentally.

description: The "middle corona" is a critical transition between the highly disparate physical regimes of the lower and outer solar corona. Nonetheless, it remains poorly understood due to the difficulty of observing this faint region (1.5-3 solar radii). New observations from the GOES Solar Ultraviolet Imager in August and September 2018 provide the first comprehensive look at this region's characteristics and long-term evolution in extreme ultraviolet (EUV). Our analysis shows that the dominant emission mechanism here is resonant scattering rather than collisional excitation, consistent with recent model predictions. Our observations highlight that solar wind structures in the heliosphere originate from complex dynamics manifesting in the middle corona that do not occur at lower heights. These data emphasize that low-coronal phenomena can be strongly influenced by inflows from above, not only by photospheric motion, a factor largely overlooked in current models of coronal evolution. This study reveals the full kinematic profile of the initiation of several coronal mass ejections, filling a crucial observational gap that has hindered understanding of the origins of solar eruptions. These new data uniquely demonstrate how EUV observations of the middle corona provide strong new constraints on models seeking to unify the corona and heliosphere.

description: We present a high-precision radial velocity (RV) survey of 719 FGKM stars, which host 164 known exoplanets and 14 newly discovered or revised exoplanets and substellar companions. This catalog updated the orbital parameters of known exoplanets and long-period candidates, some of which have decades-longer observational baselines than they did upon initial detection. The newly discovered exoplanets range from warm sub-Neptunes and super-Earths to cold gas giants. We present the catalog sample selection criteria, as well as over 100,000 radial velocity measurements, which come from the Keck-HIRES, APF-Levy, and Lick-Hamilton spectrographs. We introduce the new RV search pipeline RVSearch that we used to generate our planet catalog, and we make it available to the public as an open-source Python package. This paper is the first study in a planned series that will measure exoplanet occurrence rates and compare exoplanet populations, including studies of giant planet occurrence beyond the water ice line, and eccentricity distributions to explore giant planet formation pathways. We have made public all radial velocities and associated data that we use in this catalog.

description: The triplet and singlet low-energy parameters in the effective-range expansion for neutron--proton scattering are determined by using the latest experimental data on respective phase shifts from the SAID nucleon--nucleon database. The results differ markedly from the analogous parameters obtained on the basis of the phase shifts of the Nijmegen group and contradict the parameter values that are presently used as experimental ones. The values found with the aid of the phase shifts from the SAID nucleon--nucleon database for the total cross section for the scattering of zero-energy neutrons by protons, $σ_{0}=20.426 $b, and the neutron--proton coherent scattering length, $f=-3.755 $fm, agree perfectly with the experimental cross-section values obtained by Houk, $σ_{0}=20.436\pm 0.023 $b, and experimental scattering-length values obtained by Houk and Wilson, $f=-3.756\pm 0.009 $fm, but they contradict cross-section values of $σ_{0}=20.491\pm 0.014 $b according to Dilg and coherent-scattering-length values of $f=-3.7409\pm 0.0011 $fm according to Koester and Nistler.

Salt-flocculated organic matherial as a food source in estuarine food webs
Creators: name: Wootton, Louise Sarah
Publisher: name: University of British Columbia
Year: 2010

description: Large amounts of particulate material were found to flocculate from water collected from local, organic rich streams upon addition of salt water. This material was found to compose approximately 50% humic substances and to have a C:N ratio of about 50:1. Feeding studies using floe having various degrees of bacterial colonisation showed that bacterial abundance was an important determinant of the palatability of this material to the copepod grazer, Tigriopus californicus. Palatability of flocculant particles increased linearly with increasing bacterial abundances in the range of 0-10⁶ cells • mL⁻¹, while increases in bacterial abundances above this concentration resulted in lower than expected grazing rates. Further inoculations with single strains of bacteria isolated from the floe showed that this increased palatability occurred with only certain components of the floe fauna. Ingestion of floe colonised by a "normal" bacterial fauna was found to be beneficial for the survival of Cl and adult stages of Tigriopus and was found to sustain egg production of inseminated females. The presence of floe did not, however, result in the improved survival of the earlier naupliar stages of Tigriopus. Mass spectrometric analyses suggest that significant amounts of carbon are assimilated from floe made from water collected during the winter months. As floe is ingested at very low rates in the absence of colonising microbes, benefit from the ingestion of floe is postulated to result from the conversion of floe carbon into microbial biomass and the subsequent assimilation of those microbes by the copepod grazer. The fact that few differences exist between the IR-spectra of floe food and the faecal material derived from copepods fed a floe diet suggests that little change is undergone by the bulk of the organic matrix during ingestion and passage through the copepod gut. Ingestion of floe may therefore work to protect the flocculant material from subsequent microbial degradation by compacting the material into pellets which will be rapidly delivered to the sediments as a result of high sinking rates. Feeding studies with a variety of species collected from local coastal waters suggest that a wide spectrum of organisms may ingest flocculant material when that material is present in their environs. As flocculant material is primarily produced in the winter, a time when estuarine primary productivity is low, floe is postulated to play an important role in sustaining these organisms through periods of low food availability.

description: The proximity effect from a spin-triplet $p_x$-wave superconductor to a dirty normal-metal has been shown to result in various unusual electromagnetic properties, reflecting a cooperative relation between topologically protected zero-energy quasiparticles and odd-frequency Cooper pairs. However, because of a lack of candidate materials for spin-triplet $p_x$-wave superconductors, observing this effect has been difficult. In this paper, we demonstrate that the anomalous proximity effect, which is essentially equivalent to that of a spin-triplet $p_x$-wave superconductor, can occur in a semiconductor/high-$T_c$ cuprate superconductor hybrid device in which two potentials coexist: a spin-singlet $d$-wave pair potential and a spin--orbit coupling potential sustaining the persistent spin-helix state. As a result, we propose an alternative and promising route to observe the anomalous proximity effect related to the profound nature of topologically protected quasiparticles and odd-frequency Cooper pairs.

description: The CORSIKA program, usually used to simulate extensive cosmic ray air showers, has been adapted to work in a water or ice medium. The adapted CORSIKA code was used to simulate hadronic showers produced by neutrino interactions. The simulated showers have been used to study the spatial distribution of the deposited energy in the showers. This allows a more precise determination of the acoustic signals produced by ultra high energy neutrinos than has been possible previously. The properties of the acoustic signals generated by such showers are described.

The various form factors of $J/ψ$ transiting to a single charmed meson ($D^{(*)}_{(d,s)}$) are studied in the framework of the QCD sum rules. These form factors fully determine the rates of the weak semi-leptonic decays of $J/ψ$ and provide valuable information about the non-perturbative QCD effects. Our results indicate that the decay rate of the semi-leptonic weak decay mode $J/ψ\to D^{(*)-}_{s}+e^{+}+ν_{e}$ is at order of $10^{-10}$.

Using this measure, it is shown that the probability for the generalized single field slow roll inflation to last for $N$ e-folds is suppressed by a factor $\exp(-3N)$, and the probability for the generalized $n$-field slow roll inflation is suppressed by a much larger factor $\exp(-3nN)$. Some non-inflationary models such as the cyclic model do not suffer from this difficulty.

description: We calculate the CP averaged branching ratios and CP-violating asymmetries for $B_s^0 \to ηη, ηη^\prime$ and $η^\prime η^\prime$ decays in the perturbative QCD (pQCD) approach here. The pQCD predictions for the CP-averaged branching ratios are $Br(B_s^0 \to ηη) = \left (14.2^{+18.0}_{-7.5}) \times 10^{-6}$, $Br(B_s^0 \to ηη^\prime)= \left (12.4 ^{+18.2}_{-7.0}) \times 10^{-6}$, and $Br(B_s^0 \to η^{\prime} η^{\prime}) = \left (9.2^{+15.3}_{-4.9}) \times 10^{-6}$, which agree well with those obtained by employing the QCD factorization approach and also be consistent with available experimental upper limits. The gluonic contributions are small in size: less than 7% for $B_s \to ηη$ and $ ηη^\prime$ decays, and around 18% for $B_s \to η' η'$ decay. The CP-violating asymmetries for three decays are very small: less than 3% in magnitude.

description: The high energy neutrino emission from gamma-ray bursts (GRBs) has been expected in various scenarios. In this paper, we study the neutrino emission from early afterglows of GRBs, especially under the reverse-forward shock model and late prompt emission model. In the former model, the early afterglow emission occurs due to dissipation made by an external shock with the circumburst medium (CBM). In the latter model, internal dissipation such as internal shocks produces the shallow decay emission in early afterglows. We also discuss implications of recent Swift observations for neutrino signals in detail. Future neutrino detectors such as IceCube may detect neutrino signals from early afterglows, especially under the late prompt emission model, while the detection would be difficult under the reverse-forward shock model. Contribution to the neutrino background from the early afterglow emission may be at most comparable to that from the prompt emission unless the outflow making the early afterglow emission loads more nonthermal protons, and it may be important in the very high energies. Neutrino-detections are inviting because they could provide us with not only information on baryon acceleration but also one of the clues to the model of early afterglows. Finally, we compare various predictions for the neutrino background from GRBs, which are testable by future neutrino-observations.

description: In this work we implement the self-consistent Thomas-Fermi model that also incorporates a local conductivity model to an electron-electron bilayer system, in order to describe novel magneto-transport properties such as the Drag Phenomenon. The model can successfully account for the poor screening of the potential within the incompressible strips and its impact on the interlayer Coulomb interaction. An externally applied current in the active layer results in the tilting of the Landau levels and built-up of a Hall potential across the layer, which, in turn, induces a tilted potential profile in the passive layer as well. We investigate the effect of the current intensity, temperature, magnetic field, and unequal density of layers on the self-consistent density and potential profiles of the bilayer system.

description: The effect of bias voltages on the statistical properties of rough surfaces has been studied using atomic force microscopy technique and its stochastic analysis. We have characterized the complexity of the height fluctuation of a rough surface by the stochastic parameters such as roughness exponent, level crossing, and drift and diffusion coefficients as a function of the applied bias voltage. It is shown that these statistical as well as microstructural parameters can also explain the macroscopic property of a surface. Furthermore, the tip convolution effect on the stochastic parameters has been examined.

description: We report on theoretical and experimental investigations of the integer quantized Hall effect in narrow channels at various mobilities. The Hall bars are defined electrostatically in two-dimensional electron systems by biasing metal gates on the surfaces of GaAs/AlGaAs heterostructures. In the low mobility regime the classical Hall resistance line is proportional to the magnetic field as measured in the high temperature limit and cuts through the center of each Hall plateau. For high mobility samples we observe in linear response measurements, that this symmetry is broken and the classical Hall line cuts the plateaus not at the center but at higher magnetic fields near the edges of the plateaus. These experimental results confirm the unconventional predictions of a model for the quantum Hall effect taking into account mutual screening of charge carriers within the Hall bar. The theory is based on solving the Poisson and Schrödinger equations in a self-consistent manner.

Carineta diardi

description: Carineta diardi (colourful-cicada)
The colourful-cicada is a fully canopy species. This cicada emits signals and copulates at heights> 2 m (Fig. 1), with the field temperature ranging between 16°C and 21°C, although it sometimes performs low flights up to 2 m of the ground. Males were observed singing the calling song on the trees of various native and non-native plant families, such as Anacardiaceae, Moraceae, Pinaceae, and Sapindaceae. A pair formation was seen when a male landed on a leaf of Hovenia dulcis (a nonnative tree of Rhamnaceae) where a female was standing. No acoustic signal was heard and while the female remained fixed on the lower side of the leaf, the male attached his genitalia in a typical end-to-end position and then retracted his legs (Fig. 1C), remaining immobile until the female took flight. This was the only observed copulation at the study site and it lasted 5 min.
The C. diardi is widely distributed in the Atlantic Forest from north-eastern Brazil (Bahia) to Paraguay, Argentina (Misiones), and southern Brazil (Sanborn 2011, Núñez-Bustos 2016) (Fig. 3A). It occurs from sea level to some montane areas (from 400 to 1300 m a.s.l.) in south-eastern (São Paulo and Minas Gerais) and central Brazil (Brasília, DF) (Fig 3B).
Based on our observations, emergence in southern Brazil usually happens in September (spring in the southern hemisphere), followed by a short adult life, which can last just under 2 weeks. In just a few days, there were no more individuals singing or flying (Fig. 4A). Citizen science data for this species indicate that scattered individuals may emerge in autumn in south-eastern Brazil (São Paulo) (September to November) and Argentina (Misiones) (March to June).
Carineta diardi (colourful-cicada)
This species has a repertoire composed by flying song (N = 8) and calling song (N = 8) (Fig. 5). The acoustic activity of the species occurs between 8 a.m. and 11 a.m. The flying song (Fig. 5A) is composed of a train of clicks, which are emitted throughout the time the male keeps flying. These clicks, or echemes, are emitted at values of 12 ± 3 (8–19) while the individual remains suspended in the air. The calling song (Fig. 5B) was emitted when the males were perched, usually on leaves. The signal has a smaller duration of 0.06 ± 0.01 s (0.003 – 0.143 s) (Table 2). Significant differences were detected between flying and calling songs in the peak frequency (Mann–Whitney test, U = 1496, P <.05) and echeme duration (Mann–Whitney test, U = 115, P <.05).

A quasi-geostrophic circulation model of the Northeast Pacific Ocean
Creators: name: Cummins, Patrick F.
Publisher: name: University of British Columbia
Year: 2010

description: A limited-area quasi-geostrophic numerical model with mesoscale resolution is developed to study the circulation in the Northeast Pacific Ocean. The model domain extends from the British Columbia/Alaska coast out to 170°W and down to 45°N, and incorporates the coastline geometry and bottom topography of the region. In a benchmark experiment, the circulation is driven with a steady, climatological wind stress curl field. Statistical properties of the solution are determined from a long-term integration and compared with observations from the Gulf of Alaska. The cyclonic circulation of the model basin contains the analogue of a meandering Alaska Current. At the head of the Gulf, this current flows into an intense boundary current corresponding to the Alaskan Stream. Within the model Alaska Current, anticyclonic closed streamline features are occasionally generated which are representative of the Sitka Eddy, ln the upstream region, the model Alaskan Stream displays large amplitude aperiodic meanders, while, in the downstream region, the boundary current separates and is subject to smaller amplitude lateral meandering due to topographic waves. The occurrence of perturbations with similar characteristics in the Alaskan Stream has recently been verified in satellite AVHRR imagery. The model is also used to examine the effects of bottom topography and seasonal wind forcing on the circulation of the subpolar gyre. The characteristics of the Alaskan Stream are shown to depend crucially on the presence of the Aleutian Trench. In an experiment with a flat bottom and steady forcing, the most energetic signal is due to mesoscale eddies with a 100 day period associated with barotropic wave propagation along the Aleutian arc. Bottom topography eliminates this signal by inhibiting the nonlinear transfer of energy between the first baroclinic and the barotropic mode, thereby stabilizing the model Alaskan Stream to baroclinic instability. Experiments with a climatological seasonal cycle in the wind field show that the bottom topography has an important influence in moderating the intensity of the seasonal response. This result is used to explain the discrepancy between observations of seasonal variability in the volume transport of the Alaskan Gyre and the transport obtained in previous numerical modelling studies.

description: Precise measurements of the single spin asymmetry, $A_N$ and the double spin asymmetry, $A_{NN}$, in proton-proton (\textit{pp}) elastic scattering in the region of four-momentum transfer squared $0.001 < -t < 0.032 ({\rm GeV}/c)^2$ have been performed using a polarized atomic hydrogen gas jet target and the RHIC polarized proton beam at 24 GeV/$c$ and 100 GeV/$c$. The polarized gaseous proton target allowed us to achieve the measurement of $A_{NN}$ in the CNI region for the first time. Our results of $A_N$ and $A_{NN}$ provide significant constraints to determine the magnitude of poorly known hadronic single and double spin-flip amplitudes at this energy.

description: In this Letter we present strong arguments in favour of thoroughly revising the negative mass cosmology (NMC), which has been proposed as a simple alternative explanation of dark energy and dark matter effects, within the framework of General Relativity. We show that there are various physical predictions in this model which require fine-tuning in order to make them compatible with current cosmological surveys. In this way, the original motivation of the NMC model becomes obscured due to the imposition of fine-tuned unknown variables. We conclude that a more rigorous theoretical treatment is needed in order to make the NMC a viable cosmological model.
