Mechanical and chemical convergence of joints in three lineages of articulated coralline algae
Creators: name: Janot, Kyra G.
Publisher: name: University of British Columbia
Year: 2018

description: Macroalgae living in wave-swept environments experience a high degree of mechanical stress. Flexible algae can mitigate this stress by bending with the waves, taking on smaller, more streamlined shapes that reduce drag. Coralline algae are limited in their flexibility due to having cell walls enriched in calcium carbonate, which cause thalli to be mostly rigid. While crustose species may avoid drag by growing prostrate along the substrate, most upright coralline species have uncalcified articulations (genicula) that allow them to retain flexibility despite their calcified constraint. Articulated corallines have evolved from crustose ancestors at least three separate times, leading to articulated species within the Corallinoideae, Lithophylloideae, and Metagoniolithoideae. The repeated evolution of genicula, and the rarity of upright coralline species without them, suggests that they play a key role in the ecological success of erect corallines. While previous studies have noted structural and developmental differences among genicula in the three evolutionary lineages, I address multiple levels of genicular organization to investigate the depth of convergent evolution of these structures. I found that genicular tissues are stronger and more extensible than other fleshy seaweed tissues, reflecting the fact that genicula must undergo a high degree of stress and strain to compensate for rigidity elsewhere in the algal thallus (Ch. 2). Differences exist between articulated clades; corallinoids are particularly strong, while lithophylloids are often highly extensible (Ch. 2). Articulated clades also differ in the way genicular morphology and tissue properties are adjusted to increase thallus flexibility; corallinoids possess a high number of genicula, metagoniolithoids possess long genicula, and lithophylloids possess particularly pliant genicular tissues (Ch. 3). Both the content and structure of polysaccharides in the genicular cell wall varies depending on subfamily, reflecting differences in genicular development and potentially causing differences in material properties (Ch. 4). Results from polarized microscopy suggest that the arrangement of polysaccharides within the cell wall also plays a role in how genicular tissue responds to mechanical stress (Ch. 5). In summary, while genicula may serve similar functions in corallinoids, lithophylloids, and metagoniolithoids, I show that there is more than one way to build an articulated coralline.

description: We consider the problem of distinguishing between a set of arbitrary quantum states in a setting in which the time available to perform the measurement is limited. We provide simple upper bounds on how well we can perform state discrimination in a given time as a function of either the average energy or the range of energies available during the measurement. We exhibit a specific strategy that nearly attains this bound. Finally, we consider several applications of our result. First, we obtain a time-dependent Tsirelson's bound that limits the extent of the Bell inequality violation that can be in principle be demonstrated in a given time t. Second, we obtain a Margolus-Levitin type bound when considering the special case of distinguishing orthogonal pure states.

description: The solar images at 17 GHz by Nobeyama Radio Heliograph and in X-ray by soft X-ray telescope (SXT) on board Yohkoh satellite have been of particular interest for the estimation of solar coronal rotation using flux modulation approach. These studies established that the solar corona rotates differentially. The radio images estimate equatorial rotation period lower than those estimated by the X-ray images. The latitude profiles of the coronal rotation have temporal variability. The space-time plots of sidereal rotation period, interestingly, display clear North-South asymmetry. The asymmetry appears to change its sign in odd and even activity cycles of the Sun.

description: Ap star magnetism is often attributed to fossil magnetic fields which have not changed much since the pre-main-sequence epoch of the stars. Stable magnetic field configurations are known which could persist probably for the entire main-sequence life of the star, but they may not show the complexity and diversity exhibited by the Ap stars observed. We suggest that the Ap star magnetism is not a result of stable configurations, but is the result of an instability based on strong toroidal magnetic fields buried in the stars. The highly nonaxisymmetric remainders of the instability are reminiscent of the diversity of fields seen on Ap stars. The strengths of these remnant magnetic fields is actually between a few per cent up to considerable fractions of the internal toroidal field; this means field strengths of the order of kGauss being compatible with what is observed. The magnetic fields emerge at the surface rather quickly; rough estimates deliver time-scales of the order of a few years. Since rotation stabilizes the instability, normal A stars may still host considerable, invisible toroidal magnetic fields.

description: Since late 2019, psychologists in Australia have been working in the context of a number of weather disasters and COVID-19, the combination of which have had ongoing mental health consequences for the Australian community, requiring psychologists to meet a growing demand for services. In November and December 2022, 469 registered psychologists participated in survey about the personal and professional impacts of recent disasters, and supporting the current and future mental health needs of the Australian community. Almost one in three (31%) psychologists had been personally impacted by weather disasters since 2019, and 61.3% of psychologists reported that their close friends, family, clients, and/or colleagues were impacted. Almost all psychologists reported being impacted by COVID-19. Over 60% of psychologists had a waitlist over one month or had stopped accepting new clients. Psychologists reported increases in the severity and complexity of client presentations since late 2019, especially in relation to anxiety, stress, wellbeing, and climate distress. To manage escalating work pressures, psychologists reported engaging in professional development, formal supervision, informal peer support, and use of self-care strategies. Most psychologists reported increased flexibility and resilience in response to recent disasters. However, one third of psychologists reported experiencing symptoms of depression (39.3%) and/or anxiety (28%), 47.6% reported low wellbeing, 26.4% reported burnout (physical, emotional, and mental exhaustion), and a further one third (34.5%) were in danger of burnout. Almost half (44.8%) of the psychologists had changed job sectors or roles since 2019, usually due to undesirable work culture and unsustainable work pressure. Fewer than one in three (30.5%) psychologists said they felt well prepared to manage the mental health needs of clients in the context of future disasters. Psychologists described strategies that they expected would help relieve the current pressures on the psychology workforce, and priority areas for professional development to be better prepared to respond to future disasters. Overall, the findings from this survey indicate that Australia’s psychology workforce is at, or nearing, crisis. Given the expected increase in frequency and severity of disasters, now more than ever, it is important to support the psychology workforce to recover from recent disasters, stabilise and strengthen the workforce, and prepare the workforce to respond effectively to future disasters.

description: It has been shown that an inhomogeneously broadened optical transition shaped into an atomic frequency comb can store a large number of temporal modes of the electromagnetic field at the single photon level without the need to increase the optical depth of the storage material. The readout of light modes is made efficient thanks to the rephasing of the optical-wavelength coherence similarly to photon echo-type techniques and the re-emission time is given by the comb structure. For on-demand readout and long storage times, two control fields are used to transfer back and forth the optical coherence into a spin wave. Here, we present a detailed analysis of the spin wave storage based on chirped adiabatic control fields. In particular, we verify that chirped fields require significantly weaker intensities than $π$-pulses. The price to pay is a reduction of the multimode storage capacity that we quantify for realistic material parameters associated with solids doped with rare-earth-metal ions.

description: We present wide-field imaging of the 2007 outburst of Comet 17P/Holmes obtained serendipitously by SuperWASP-North on 17 nights over a 42-night period beginning on the night (2007 October 22-23) immediately prior to the outburst. Photometry of 17P's unresolved coma in SuperWASP data taken on the first night of the outburst is consistent with exponential brightening, suggesting that the rapid increase in the scattering cross-section of the coma could be largely due to the progressive fragmentation of ejected material produced on a very short timescale at the time of the initial outburst, with fragmentation timescales decreasing from t(frag)~2x10^3 s to t(frag)~1x10^3 s over our observing period. Analysis of the expansion of 17P's coma reveals a velocity gradient suggesting that the outer coma was dominated by material ejected in an instantaneous, explosive manner. We find an expansion velocity at the edge of the dust coma of v(exp) = 0.55+/-0.02 km/s and a likely outburst date of t_0=2007 October 23.3+/-0.3, consistent with our finding that the comet remained below SuperWASP's detection limit of m(V)~15 mag until at least 2007 October 23.3. Modelling of 17P's gas coma indicates that its outer edge, which was observed to extend past the outer dust coma, is best explained with a single pulse of gas production, consistent with our conclusions concerning the production of the outer dust coma.

Anion height as a controlling parameter for the superconductivity in iron pnictides and cuprates

Year: 2010
Subjects: subject: Superconductivity (cond-mat.supr-con)

description: Both families of high $T_c$ superconductors, iron pnictides and cuprates, exhibit material dependence of superconductivity. Here, we study its origin within the spin fluctuation pairing theory based on multiorbital models that take into account realistic band structures. For pnictides, we show that the presence and absence of Fermi surface pockets is sensitive to the pnictogen height measured from the iron plane due to the multiorbital nature of the system, which is reflected to the nodeless/nodal form of the superconducting gap and $T_c$. Surprisingly, even for the cuprates, which is conventionally modeled by a single orbital model, the multiorbital band structure is shown to play a crucial role in the material dependence of superconductivity. In fact, by adopting a two orbital model that considers the $d_{z^2}$ orbital on top of the $d_{x^2-y^2}$ orbital, we can resolve a long standing puzzle of why the single layered Hg cuprate have much higher $T_c$ than the La cuprate. Interestingly, here again the apical oxygen height measured from the CuO$_2$ plane plays an important role in determining the relative energy difference between $d_{x^2-y^2}$ and $d_{z^2}$ orbitals, thereby strongly affecting the superconductivity.

The proofs use a classical infinite product formula involving the gamma function. We also extend Catalan's 1873 infinite product of radicals for $e$ to Catalan-type products for $e/4,\sqrt{e}$, and $e^{3/2}/2$. Here the proofs use Stirling's formula. Finally, we find an analog for $e^{2/3}/\sqrt3$ of Pippenger's 1980 infinite product for $e/2$, and we conjecture that they can be generalized to a product for a power of $e^{1/K}$.

The influence of enzymatic liquefaction and slurry rheology on high-solids cellulose hydrolysis
Creators: name: Van Der Zwan, Timo William
Publisher: name: University of British Columbia
Year: 2018

description: Enzyme-mediated hydrolysis of lignocellulosic materials for their conversion into bioproducts would benefit significantly if high solids concentrations (low water-to-biomass ratios) could be processed effectively. However, the fibrous nature of lignocellulosic biomass makes effective reaction mixing difficult, resulting in mass transfer limitations that reduce process yields. Overcoming these rheological challenges will require a better understanding of the substrate properties that influence slurry rheology, and in particular, how the action of carbohydrate-active enzymes can better facilitate slurry viscosity reduction, or ‘enzymatic liquefaction’. To this end, the work described in this thesis assessed: the underlying causes of the rheological challenge of high-solids bioconversion; the possible mechanisms of enzymatic liquefaction; how liquefaction is influenced by the nature of the substrate; and the roles the various enzymes play in liquefaction. It was apparent that the relationship between substrate properties, slurry rheology and high-solids hydrolysis kinetics is complex and multifaceted. Substrate–water interactions were shown to be a key determinant that influenced the mass transfer boundary and the scaling of yield stress with solids loading. The yield stress profiles of the various pretreated substrates varied extensively, indicating that ‘high solids’ is a relative, substrate-dependent quality. Substrate rheological characteristics, especially slurry yield stress, were shown to be directly linked to liquefaction efficiency and to reductions in hydrolysis yield with increasing solids loading. It appeared that enzyme-mediated liquefaction of biomass was achieved through a combination of material dilution, particle fragmentation and alteration of interparticle interactions. Cellobiohydrolases and endoglucanases were shown to be the key enzymes involved in these mechanisms. However, the effectiveness of the various enzymes was strongly influenced by the substrate’s physicochemical properties and concentration. Notably, an enzyme’s low-solids slurry viscosity-reducing capacity did not necessarily reflect its capacity to catalyze liquefaction at high solids loadings. Furthermore, reaction efficiencies tested at low solids loadings did not reliably predict efficiency at high solids due to substrate-specific rheological differences. In summary, this work provided rheological and enzymological insights into the highly disparate reaction kinetics and rheological challenge prevailing at commercially relevant substrate concentrations.

description: Contact processes describe the transmission of distinct properties of nodes via the links of a network. They provide a simple framework for many phenomena, such as epidemic spreading and opinion formation. Combining contact processes with rules for topological evolution yields an adaptive network in which the states of the nodes can interact dynamically with the topological degrees of freedom. By moment-closure approximation it is possible to derive low-dimensional systems of ordinary differential equations that describe the dynamics of the adaptive network on a coarse-grained level. In this chapter we discuss the approximation technique itself as well as its applications to adaptive networks. Thus, it can serve both as a tutorial as well as a review of recent results.

The combined effect of interactions and Hanbury-Brown Twiss interference results in unique spatial correlations which depend on the strength of the interaction, but not on its sign. The results are explained in light of the two-particle spectrum and the physics of attractively and repulsively bound pairs. We experimentally measure the weak interaction limit of these effects in nonlinear photonic lattices. Finally, we discuss an experimental approach to observe the strong interaction limit using single atoms in optical lattices.

description: The present work deals with the detection of phase changes in an exoplanetary system. HD 46375 is a solar analog known to host a non-transiting Saturn-mass exoplanet with a 3.0236 day period. It was observed by the CoRoT satellite for 34 days during the fall of 2008. We attempt to identify at optical wavelengths, the changing phases of the planet as it orbits its star. We then try to improve the star model by means of a seismic analysis of the same light curve and the use of ground-based spectropolarimetric observations. The data analysis relies on the Fourier spectrum and the folding of the time series. We find evidence of a sinusoidal signal compatible in terms of both amplitude and phase with light reflected by the planet. Its relative amplitude is Delta Fp/F* = [13.0, 26.8] ppm, implying an albedo A=[0.16, 0.33] or a dayside visible brightness temperature Tb ~ [1880,2030] K by assuming a radius R=1.1 R_Jup and an inclination i=45 deg. Its orbital phase differs from that of the radial-velocity signal by at most 2 sigma_RV. However, the tiny planetary signal is strongly blended by another signal, which we attribute to a telluric signal with a 1 day period. We show that this signal is suppressed, but not eliminated, when using the time series for HD 46179 from the same CoRoT run as a reference. This detection of reflected light from a non-transiting planet should be confirmable with a longer CoRoT observation of the same field. In any case, it demonstrates that non-transiting planets can be characterized using ultra-precise photometric lightcurves with present-day observations by CoRoT and Kepler. The combined detection of solar-type oscillations on the same targets (Gaulme et al. 2010a) highlights the overlap between exoplanetary science and asteroseismology and shows the high potential of a mission such as Plato.

Stock market and private consumption in Malaysia

description: The paper analyzes the influence of the stock market on aggregate consumption in Malaysia using a battery of time series approaches ? the ARDL cointegration test, an error-correction modeling and a vector autoregression (VAR). In the analysis, real consumption is specified to depend linearly on real income and real stock market wealth as measured by real market capitalization. The ARDL cointegration test indicates the presence of a long-run relationship between consumption and its determinants, real income and real stock market wealth. At the same time, we also note positive short-run coefficient of current changes in real stock market wealth in the dynamic equation of real consumption. Finally, the variance decompositions and impulse-response functions simulated from the estimated VAR indicate a causal pattern that runs from real stock market wealth to real activities (consumption and income). Accordingly, based on these findings, the stock market wealth effect is unequivocally supported in Malaysia.

description: The widespread adoption of Building Information Modelling (BIM) in the Architecture, Engineering, Construction and Owner (AECO) Industry has led to data-intensive projects. The growth of data in the digital environment may affect compliance with the Owner’s BIM requirements and the overall project goal to utilize BIM for downstream purposes. Existing compliance assessment practices utilized by industry are very cost and time intensive, and ineffective at supporting design decision-making. Three specific challenges were observed in our research. First, the quality of information integrated in the BIM models may be inaccurate, thus impacting the integrity of BIM and posing a risk to the project. Second, the inundation of unstructured data generated in the BIM environment impacts the team’s ability to manage information and extract useful insights to drive actions. Third, project stakeholders are often less involved than BIM experts in the BIM compliance process due to limited understanding of BIM platforms and drive their business-level decisions without understanding the status of design data. The objective of this research is to address these three specific challenges using an action-research (AR) methodology. We present the outcomes of an action-research (AR) project undertaken with a global design consultant, Stantec, in the context of the design of a large healthcare facility. The objective of AR was to create a robust yet simple-to-use compliance assessment workflow. The key metrics for BIM compliance were identified and evaluated over the course of this study. An automated data analytics and visualization workflow was developed to simplify the compliance assessment process of BIM-based projects. Visual programming was used to automate the BIM data analytics to represent key compliance metrics and streamline complex workflows. The interactive visualization provides actionable information to project teams in a way that enables project experts to gain insights more effectively to inform decisions and to help manage compliance with Owner’s BIM requirements. The workflow developed in this research was utilized by the design consultants on the case study project to achieve compliance with the Owner’s BIM requirements, and the Regional BIM Lead at Stantec decided to use this workflow on all their BIM projects across the province.

The Thermal Instability of Solar Prominence Threads

description: The fine structure of solar prominences and filaments appears as thin and long threads in high-resolution images. In H-alpha observations of filaments, some threads can be observed for only 5 - 20 minutes before they seem to fade and eventually disappear, suggesting that these threads may have very short lifetimes. The presence of an instability might be the cause of this quick disappearance. Here, we study the thermal instability of prominence threads as an explanation of their sudden disappearance from H-alpha observations. We model a prominence thread as a magnetic tube with prominence conditions embedded in a coronal environment. We assume a variation of the physical properties in the transverse direction, so that the temperature and density continuously change from internal to external values in an inhomogeneous transitional layer representing the particular prominence-corona transition region (PCTR) of the thread. We use the nonadiabatic and resistive magnetohydrodynamic equations, which include terms due to thermal conduction parallel and perpendicular to the magnetic field, radiative losses, heating, and magnetic diffusion. We combine both analytical and numerical methods to study linear perturbations from the equilibrium state, focusing on unstable thermal solutions. We find that thermal modes are unstable in the PCTR for temperatures higher than 80,000 K, approximately. These modes are related to temperature disturbances that can lead to changes in the equilibrium due to rapid plasma heating or cooling. For typical prominence parameters, the instability time scale is of the order of a few minutes and is independent of the form of the temperature profile within the PCTR of the thread. This result indicates that thermal instability may play an important role for the short lifetimes of threads in the observations.

description: Halichondria cavernosa n. sp. PI. XIX, fig. 16. Un spécimen paraissant entier et semblant n'avoir pas eu de support. Forme allongée; longueur 35 mm., largeur 10 mm., hauteur 5 à 7 mm. Surface finement hispide. Consistance assez ferme mais compressible. Couleur violacée, probablement à cause du séjour de l'échantillon dans un bocal d'alcool ayant contenu des lotrochota. Face inférieure égale, continue, imperforée; face supérieure anfractueuse donnant accès dans un système de cavités internes à parois minces communiquant entre elles par des pertuis étroits et arrondis. Ectosome représenté par une mince pellicule brillante dépourvue de spicules. Enchevêtrés sans ordre dans le choanosome, les spicules sont de grands oxes, fusiformes, acérés, légèrement courbés, de taille assez inégale, atteignant 1 mm. et plus de longueur et 17 ^ d'épaisseur au centre; souvent leurs pointes s'émoussent ou se froncent et tendent à s'atrophier. Par ses lacunes et par ses mégasclères, cette Eponge offre une certaine ressemblance avec Y Halichondria sp.? des îles Philippines dont Ridley et Dendy ont tracé la description (20, p. 8) et qui, comme elle, paraît avoir vécu sans attache, dans des eaux peu profondes.

description: The spectral characteristics of a fiber Bragg grating (FBG) with a transversely inhomogeneous refractive index profile, differs con- siderably from that of a transversely uniform one. Transmission spectra of inhomogeneous and asymmetric FBGs that have been inscribed with focused ultrashort pulses with the so-called point-by-point technique are investigated. The cladding mode resonances of such FBGs can span a full octave in the spectrum and are very pronounced (deeper than 20dB). Using a coupled-mode approach, we compute the strength of resonant coupling and find that coupling into cladding modes of higher azimuthal order is very sensitive to the position of the modification in the core. Exploiting these properties allows precise control of such reflections and may lead to many new sensing applications.

description: Chalinula Montagui Fleming. 188^. Reniera sp.? Ridley (19, p. 410). Deux échantillons, mous, fragiles, creux, dressés; l'un, jaunâtre, comprimé et rameux, grêle, haut de 50 mm., l'autre, plus gris, cylindrique, fistuleux, mesurant 45 mm. de hauteur et 1 mm. de diamètre. Leur mollesse, leurs cellules sphéruleuses en files avec ligament élastique, leurs lignes squelettiques unispiculées, leur oxes courts et relativement gros, à pointes brèves et acérées, me les font déterminer comme des Chalinula Montagui. Les spicules sont cependant un peu plus petits que d'ordinaire, 1 10 a de longueur sur 6 p d'épaisseur, mais nous savons l'espèce sujette à des variations. Les oxes se montrent souvent tronqués à l'un des bouts ou aux deux extrémités à la fois, comme cela s'observe si fréquemment sur les spécimens de la Manche et comme cela était de règle dans les individus pour lesquels Bowerbank avait créé l'espèce Isodictya varians. Il n'est pas douteux pour moi que ces Eponges soient de même espèce que celle de Port-Darwin, Reniera sp., décrite par Ridley. Distribution Europe occidentale; Port Darwin; Amboine.

description: We present preliminary measurements of $Z/γ^*$+jets, $W+c$ and $Z+b+X$ at the Tevatron, and review recent measurements of vector boson plus inclusive and heavy-flavor jets production. All measurements are in agreement with next-to-leading-order QCD calculations within the experimental and theoretical uncertainties. We also point to comparisons of the production rate and kinematics of the data with several Monte Carlo simulation programs of vector boson + jets processes.
