description: The moduli in a 4D N=1 heterotic compactification on an elliptic CY, as well as in the dual F-theoretic compactification, break into "base" parameters which are even (under the natural involution of the elliptic curves), and "fiber" or twisting parameters; the latter include a continuous part which is odd, as well as a discrete part. We interpret all the heterotic moduli in terms of cohomology groups of the spectral covers, and identify them with the corresponding F-theoretic moduli in a certain stable degeneration. The argument is based on the comparison of three geometric objects: the spectral and cameral covers and the ADE del Pezzo fibrations. For the continuous part of the twisting moduli, this amounts to an isomorphism between certain abelian varieties: the connected component of the heterotic Prym variety (a modified Jacobian) and the F-theoretic intermediate Jacobian. The comparison of the discrete part generalizes the matching of heterotic 5brane / F-theoretic 3brane impurities.

description: The interactions between transport proteins and drugs are very important from the pharmacological point of view. In this study, using fluorescence and circular dichroism (CD) techniques, we investigated the interaction between human serum albumin (HSA) and incretin antidiabetic drug – exenatide. Moreover, the effect of common metal ions (Ca2+, Zn2+, Cr3+) on the exenatide–HSA binding – was also described. Based on the experimental data under pseudophysiological conditions, the calculated binding constant values are on the order of 104 M−1, and the constants are lower in the presence of metal ions. We observed the increase of the hydrophobicity near the tryptophan-214 residue in subdomain IIA, but almost no change in the hydrophobicity surrounding tyrosine residues. A similar effect on the tryptophan microenvironment is influenced by metal ions. The calculated thermodynamic parameters indicated that the characteristic electrostatic and hydrophobic interactions play an important role in the albumin–exenatide complexes. The CD studies showed that exenatide does not change the secondary structure of the protein but used metal ions have some impact on albumin α-helical content. Communicated by Ramaswamy H. Sarma
'Me is not a stable reality' : negotiations of identity in the poetry of Dorothy Auchterlonie, Rosemary Dobson, Dorothy Hewett and J.S. Harry

description: In recent years, scholars have paid considerable attention to Australian women's fiction, resulting in a thorough re-assessment of the canon.Many of Australia's most accomplished women poets, however, have not received adequate critical attention, and available statistics suggest that there is still a marked bias in favour of Australian male poets. This thesis considers the work of several poets who, while recognised as significant in our cultural heritage, have not been the subject of a body of sustained criticism. The four poets-Dorothy Auchterlonie (1915-1991), Rosemary Dobson (1920-), Dorothy Hewett (1923-) and J.S. Harry (1939-)-represent a tradition which has seen women publishing poetry of great quality over many years.This thesis adds to an emerging body of criticism which has focused to date on a small number of Australian women poets, notably Judith Wright and Gwen Harwood. The Introduction to this thesis outlines the critical bias in favour of male poets, and proposes an approach to the poetry which takes into account contemporary feminist and post-structural critical practices. The four chapters examine the poetry of Auchterlonie, Dobson, Hewett and Harry, in order of their dates of birth. Chapter One considers Auchterlonie's poetry, and in particular the ways in which it problematises the more 'public' prose writing and the public persona of Dorothy Green. Chapter Two traces Rosemary Dobson's fifty years of published poetry, arguing that her work has previously been considered too narrowly as concerned with abstractions such as Art and Time. I argue that her work can also be seen as a sustained meditation on connection and the possibilities of translation. Chapter Three examines Dorothy Hewett's poetry, reading it particularly in relation to her drama and prose. In this chapter I demonstrate the ways in which Hewett's writing across several genres sees her reworking and reweaving material throughout her writing life. In Chapter Four I show that J.S. Harry continues the tradition established by the other three poets, especially in her preoccupation with connections between writing and experience. Each of the chapters explores the concept of an 'unstable' identity, and the imaginative freedom which this allows. Finally, my Conclusion draws together some of these threads, and argues again that a body of critical writing on these women is essential to a full understanding of Australian writing.

description: The framework of inner product norm preserving relaxation Runge-Kutta methods (David I. Ketcheson, \emph{Relaxation Runge-Kutta Methods: Conservation and Stability for Inner-Product Norms}, SIAM Journal on Numerical Analysis, 2019) is extended to general convex quantities. Conservation, dissipation, or other solution properties with respect to any convex functional are enforced by the addition of a {\em relaxation parameter} that multiplies the Runge-Kutta update at each step. Moreover, other desirable stability (such as strong stability preservation) and efficiency (such as low storage requirements) properties are preserved. The technique can be applied to both explicit and implicit Runge-Kutta methods and requires only a small modification to existing implementations. The computational cost at each step is the solution of one additional scalar algebraic equation for which a good initial guess is available. The effectiveness of this approach is proved analytically and demonstrated in several numerical examples, including applications to high-order entropy-conservative and entropy-stable semi-discretizations on unstructured grids for the compressible Euler and Navier-Stokes equations.

description: Rapid transit is crucial to Metropolitan New York's economy and quality of life. However, the long-term effectiveness of the city's rapid transit system and the causes of its failures and successes are unknown. This research (1) examines the cost, capital investment, railway network, equipment, fares, and operations of rapid transit in New York from 1870 to 2010 and (2) examines long-term economic and political causes of effective and efficient rapid transit. The figures reveal three distinct eras: 1870 to 1940, characterized by unprecedented expansion and improvement; 1940 to 1980, characterized by stagnation and decline; and 1980 to 2010, characterized by stabilization and rejuvenation. Rising labor costs and declining productivity are the proximate cause of the system's past and present failures. The central implication of this research is that-in the long-term-the best means of achieving effective and efficient rapid transit is via government establishment and protection of objective, secure, and just property rights for private ownership and operation. This is consistent with a substantial body of economic theory, albeit not conventional neoclassical economics, which frequently treats transit as a special case. This conflict is linked to faulty assumptions underlying neoclassical economic theory.

description: Bovine serum albumin (BSA) is a widely recognized plasma protein for its ubiquitous function as one of the paramount transporter of different drugs and enzymes inside biological systems. HPFQ, a member of azapodophyllotoxin family, has been observed to be highly bioactive against a majority of cancer cell lines; while subsequently showing impressive fluorescent properties throughout the polarity scale. However, further pursuit into compliance of this bioactive fluorophore with carrier protein remains imperative for excavating its suitable transporter inside human body. The present biophysical spectroscopic study attempts to exhibit the adaptability of BSA towards a potential therapeutic fluorophore (HPFQ) by combining in vitro optical spectroscopy and in silico molecular docking. The competitive site-binding studies demonstrated that BSA nurtures neutral anti-cancer fluorophore HPFQ into Sudlow site I, where it experiences varying interactions with surrounding hydrophobic amino acid residues viz. Phe 205, Trp 213, Ala 209, Leu 330, Ala 349, Leu 480 etc. HPFQ gets accommodated at the vicinity of Trp-213 in BSA and initiates operation of FRET between them. Adaptation of HPFQ encourages an allosteric modulation, leading to a minor deformation in secondary protein structure, which probably allows the invading water molecules to increase the micropolarity of the adjacent environment around Trp-213. HPFQ assumes to administer conformational alteration in BSA and regulate emissive population of two tryptophan residues Trp-134 and Trp-213. The amalgamated spectroscopic investigation described herein may encourage design of azapodophyllotoxin based potential therapeutic agents for effective in vivo bio-circulation using BSA-based drug distribution systems.

Bending rigidity of stiff polyelectrolyte chains: Single chain and a bundle of multichains

description: We study the bending rigidity of highly charged stiff polyelectrolytes, for both a single chain and many chains forming a bundle. A theory is developed to account for the interplay between competitive binding of counterions and charge correlations in softening the polyelectrolyte (PE) chains. The presence of even a small concentration of multivalent counterions leads to a dramatic reduction in the bending rigidity of the chains that are nominally stiffened by the repulsion between their backbone charges. The variation of the bending rigidity as a function of $f_{0}$, the fraction of charged monomers on the chain, does not exhibits simple scaling behavior; it grows with increasing $f_{0}$ below a critical value of $f_{0}$. Beyond the critical value, however, the chain becomes softer as $f_{0}$ increases. The bending rigidity also exhibits intriguing dependence on the concentration of multivalent counterion $n_{2}$; for highly charged PEs, the bending rigidity decreases as $n_2$ increases from zero, while it increases with increasing $n_{2}$ beyond a certain value of $n_{2}$. When polyelectrolyte chains form a $N$-loop condensate (e.g., a toroidal bundle formed by $N$ turns (winds) of the chain), the inter-loop coupling further softens the condensate, resulting in the bending free energy of the condensate that scales as $N$ for large $N$.

description: Generalising the concept of Bell nonlocality to networks leads to novel forms of correlations, the characterization of which is however challenging. Here we investigate constraints on correlations in networks under the two natural assumptions of no-signaling and independence of the sources. We consider the ``triangle network'', and derive strong constraints on correlations even though the parties receive no input, i.e. each party performs a fixed measurement. We show that some of these constraints are tight, by constructing explicit local models (i.e. where sources distribute classical variables) that can saturate them. However, we also observe that other constraints can apparently not be saturated by local models, which opens the possibility of having nonlocal (but non-signaling) correlations in the triangle network.

description: Effective monitoring and control over one’s thinking, or effective metacognition, is a central component to many cognitive tasks and thus is essential to optimize learning (Metcalfe, 1993; Paul, 1992; Reder, 1987; Reder & Ritter, 1992; Schneider & Lockl, 2002; Simon & Newell, 1971; Willingham, 2007). Many factors impact how strategies are implemented. We know a good deal about the cognitive variables that affect implementation of cognitive strategies, but nothing about personality or motivational traits that contribute to effective metacognitive strategy use. This study aimed to explore and clarify the relationship between personality traits, implicit theories of intelligence (Dweck, 1999) and metacognitive control over study time allocation and subsequent test performance. The independent variables included the personality traits described in the Five Factor model (McCrae & Costa, 1997; Neuroticism, Extraversion, Openness, Agreeableness, and Conscientiousness) and participants’ implicit theories of intelligence (entity or incremental theory), as well as one between-subjects factor, which was time allotted to study passages, or time pressure (High Time Pressure vs. Low Time Pressure). The dependent variables included test performance and metacognitive strategy used. This study used a study-time allocation paradigm similar to the design used in the Son and Metcalfe (2000) study, where participants first ranked passages based on difficulty and interest, then studied the passages under either high or low time pressure. Participants were tested on their understanding of the material after studying. Participants also completed self-report measures of personality and implicit theories of intelligence. Primary findings revealed that participants high on Conscientiousness allocated more study-time to passages judged as interesting compared to participants who were average or low on Conscientiousness. Additionally, when faced with time constraints, participants who identified with an incremental theory of intelligence were more likely to allocate study-time to passages judged as interesting compared to participants who did not identify with an incremental theory of intelligence. Openness was positively related to test performance, and Extraversion was negatively related to test performance. Lastly, the trait Openness was significantly related to having an incremental theory of intelligence.

description: The bilayered rhodium oxide Sr3Rh2O7 was synthesized by high-pressure and high-temperature heating techniques. The single-phase polycrystalline sample of Sr3Rh2O7 was characterized by measurements of magnetic susceptibility, electrical resistivity, specific heat, and thermopower. The structural characteristics were investigated by powder neutron diffraction study. The rhodium oxide Sr3Rh2O7 [Bbcb, a = 5.4744(8) A, b = 5.4716(9) A, c = 20.875(2) A] is isostructural to the metamagnetic metal Sr3Ru2O7, with five 4d electrons per Rh, which is electronically equivalent to the hypothetic bilayered ruthenium oxide, where one electron per Ru is doped into the Ru-327 unit. The present data show the rhodium oxide Sr3Rh2O7 to be metallic with enhanced paramagnetism, similar to Sr3Ru2O7. However, neither manifest contributions from spin fluctuations nor any traces of a metamagnetic transition were found within the studied range from 2 K to 390 K below 70 kOe.

description: Following to the lines drawn in my previous paper about the S=0 relativistic oscillator I build up an oscillatorlike system which can be named as the S=1 Proca oscillator. The Proca field function is obtained in the framework of the Bargmann-Wigner prescription and the interaction is introduced similarly to the S=1/2 Dirac oscillator case regarded by Moshinsky and Szczepaniak. We obtained the intriguing rule of quantization: E = \hbar ω/2 for the parity states (-1)^j and E = \pm \hbar ω(j+1/2) for the parity states -(-1)^j. There are no radial excitations. Finally, I apply the above-mentioned procedure to the case of the two-body relativistic oscillator.

description: The microbial transformation of androst-4-ene-3,17-dione (4-AD; I) by three fungal species, involved Fusarium solani BH1031, Aspergillus awamori MH18 and Mucor circinelloides W12, has been studied. The latter two fungi were studied for the first time on biotransformation of 4-AD. The main product obtained by Fusarium solani BH1031 was 17α-oxa-D-homo-androst-1,4-diene-3,17-dione (testolactone; IV), which can be used as an anticancer agent. The main derivative yielded by Aspergillus awamori MH18 was 11α-hydroxyandrost-4-ene-3,17-dione (11α-OH-4-AD; VI), which was an important intermediate to produce Eplerenone. Meanwhile, the microbial transformation of 4-AD by Mucor circinelloides W12 produced three derivatives. Possible metabolic pathway of 4-AD via Fusarium solani BH1031 was proposed. Furthermore, the optimization for the production of 11α-OH-4-AD was carried out and the conversion rate reached to 84.0%. In this process, the dextrin and corn flour showed significant effects by response surface analysis.

description: Markov chain Monte Carlo algorithms have important applications in counting problems and in machine learning problems, settings that involve estimating quantities that are difficult to compute exactly. How much can quantum computers speed up classical Markov chain algorithms? In this work we consider the problem of speeding up simulated annealing algorithms, where the stationary distributions of the Markov chains are Gibbs distributions at temperatures specified according to an annealing schedule. We construct a quantum algorithm that both adaptively constructs an annealing schedule and quantum samples at each temperature. Our adaptive annealing schedule roughly matches the length of the best classical adaptive annealing schedules and improves on nonadaptive temperature schedules by roughly a quadratic factor. Our dependence on the Markov chain gap matches other quantum algorithms and is quadratically better than what classical Markov chains achieve. Our algorithm is the first to combine both of these quadratic improvements. Like other quantum walk algorithms, it also improves on classical algorithms by producing "qsamples" instead of classical samples. This means preparing quantum states whose amplitudes are the square roots of the target probability distribution. In constructing the annealing schedule we make use of amplitude estimation, and we introduce a method for making amplitude estimation nondestructive at almost no additional cost, a result that may have independent interest. Finally we demonstrate how this quantum simulated annealing algorithm can be applied to the problems of estimating partition functions and Bayesian inference.

description: This research program (EmetStudy) extends emetophobia-related knowledge in seven key areas and achieves three milestones in the treatment of emetophobia. The first milestone is that it is the largest emetophobia treatment study conducted to date. There was a total of 107 participants completed treatment using an online cognitive behavioural therapy (CBT) program, administered by a single therapist over a 12 month period. Second, two new measures of emetophobia related symptoms were developed and validated using a large pool (N = 459) of emetophobia treatment seekers. Finally, EmetStudy led to the publication of the first, and currently the only non-retrospective, structured clinical interviews (N = 64) to ascertain emetophobia comorbidity rates, confirming that comorbidity rates may be lower than previously suggested. Overall this thesis examined seven key research areas that included two treatment goals and five theory related goals, outlined below. The two treatment goals were: (1) to assess the effectiveness of an online cognitive-behavioural internet therapy developed specifically for the treatment of emetophobia and (2) understand the progress of participants during treatment by quantifying commencement, dropout and completion of treatment. The treatment program was conducted in two phases with a Pilot and Main Study.

description: We introduce a deep neural network to model in a symmetry preserving way the environmental dependence of the centers of the electronic charge. The model learns from ab-initio density functional theory, wherein the electronic centers are uniquely assigned by the maximally localized Wannier functions. When combined with the Deep Potential model of the atomic potential energy surface, the scheme predicts the dielectric response of insulators for trajectories inaccessible to direct ab-initio simulation. The scheme is non-perturbative and can capture the response of a mutating chemical environment. We demonstrate the approach by calculating the infrared spectra of liquid water at standard conditions, and of ice under extreme pressure, when it transforms from a molecular to an ionic crystal.

description: Social science research on social inequality in Latin America emphasizes the role that residential distribution of social groups in urban space plays in the production and/or reproduction of asymmetries of social positioning there in conjunction with the acceleration of economic globalization in the 1990s. Meanwhile, spaces absolutely receptive to social diversity, such as public streets and squares in Latin American historical centers during the shop opening hours, are less studied. This paper presents the analysis of a Brazilian case, São Paulo’s cathedral square, where I gathered ethnographic data on 39 occasions (Monday and Friday afternoons) in 2013. Applying particular dialectical and phenomenological perspectives, a Lefebvrean and Goffmanian one, I aim to answer how and why the bodily use pedestrians made of this place may interfere in the (re)production of social equality in São Paulo at this point in time. From this research, secular body-behavioral and moral inequalities emerge as important issues.

description: Duality is considered for the perturbation theory by deriving, given a series solution in a small parameter, its dual series with the development parameter being the inverse of the other. A dual symmetry in perturbation theory is identified. It is then shown that the dual to the Dyson series in quantum mechanics is given by a recent devised series having the adiabatic approximation as leading order. A simple application of this result is given by rederiving a theorem for strongly perturbed quantum systems.

description: Der vorliegende Beitrag analysiert das Zusammentreffen von Progressionsvorbehalt und Besteuerung von außerordentlichen Einkünften. Bei dieser Fallkonstellation greifen mehrere Tarifvorschriften ineinander, so dass die Berechnung der gesamten tariflichen Einkommensteuer nicht trivial erscheint. In dem vorliegenden Beitrag wird theoretisch und empirisch analysiert, ob in der beschriebenen Konstellation Tarifverwerfungen identifiziert werden können. Diese werden angenommen, wenn die Grenzsteuersätze negativ sind oder über 100% liegen. Die theoretische Analyse verdeutlicht, dass derartige arbiträre Grenzsteuersatzverläufe existieren. Anhand der empirischen Auswertung der Einkommensteuerstatistik kann gezeigt werden, dass die theoretischen Überlegungen auch in der Realität vorzufinden sind. Ferner belegt die empirische Analyse, dass das Zusammentreffen von Progressionsvorbehalt und Besteuerung von außerordentlichen Einkünften im Veranlagungsverfahren keineswegs exotisch ist. Vielmehr werden hier wohl Fälle angesprochen, in denen ein Arbeitnehmer mit Zahlung einer Abfindung aus der Berufstätigkeit ausscheidet und danach für eine gewisse Zeit noch Lohnersatzleistungen bezieht. Bei dieser Fallkonstellation muss dann aber konstatiert werden, dass sich nicht gewollte Tarifeffekte einstellen können.

 Type: MNHN-LBIM-C-1999–01 (holotype /alcohol). South coast, Canal Woodin, New Caledonia (28 m depth). R-1360.
 Colour: Cormus of holotype bright yellow, white when preserved in alcohol.
 Description: Cormus formed of thin, regularly anastomosed tubes. There are no water-collecting tubes. The skeleton of the tubes has no special organization, comprising a thin meshwork of equiangular and equiradiate triactines (Fig. 11A). Actines are straight and conical, with a sharp distal tip. They are slightly undulated at the tip.
 Biochemical studies separated C. clathrus from another yellow clathrina we earlier named C. aurea (Solé-Cava et al., 1991), suggesting that C. clathrus is not widespread. Based on this result, Borojevic & Klautau (2000) recognized the specimen from New Caledonia as a new species. The main difference between this and other yellow clathrinas relates to the tip of the actines of the triactines, which is sharp in C. chrysea and rounded in C. clathrus and C. aurea. The yellow colour of the cormus and the skeleton composed only of triactines with cylindrical and undulated actines suggest that these clathrinas constitute a group of closely related species.
 Breitfuss (1897) reported a yellow clathrina he called C. clathrus in the Indo-Pacific region (Ternate). Borojevic & Klautau (2000) commented that he was probably referring to C. chrysea.
 In the original description of C. chrysea, the micrometry of the triactines was 105 Mm (±9 Mm)/10 Mm (±1 Mm).

description: The model equations for storm surge and tsunamis most commonly used are the shallow water equations with addition of appropriate source terms for bathymetry. Traditional approaches will need to resolve the mesh to discretize small-scale structure, which impacts the time-step size to be proportional to the size of cells. In this thesis, a novel approximate Riemann solver was developed in order to deal with the existence of barrier without restricting the time-step due to small cells. Because of the wave redistribution method and proper ghost cells setting, the novel Riemann solver maintained properties including mass and momentum conservation, the well-balancing properties and robustness at the wet-dry interface. The solver also preserves nonnegative water depth and prevents leakage. A modified h-box method is applied so the algorithm can overcome restrictions of small time-step sizes.
      The work has been done in the context of the GeoClaw platform with retaining the capabilities of GeoClaw solver. At the same time, the special developed Riemann solver extends the package to handle the sub-grid-scale effects of barriers. Incorporating the solver developed in this work into the GeoClaw framework has allowed to leverage GeoClaw’s ability to handle complex bathymetry and real applications.

description: An efficient and clean method was developed for the three components, one-pot synthesis of pyrimidinone/thione derivatives using cyclopentanone, variety of aromatic aldehydes, and urea/thiourea by using cyanuric chloride catalyzed Biginelli-type reaction. The reactions proceed under room temperature in presence of cyanuric catalyst in acetonitrile solvent. Under similar conditions, urea/thiourea exhibited similar behavior and aliphatic aldehydes showed lower reactivity than aromatic aldehydes.

description: Chronic obstructive pulmonary disease (COPD) is characterized by periodic episodes of worsening symptom (e.g., shortness of breath, irregular breathing, and worse coughing with increased phlegm production), also called pulmonary exacerbations. Inflammation is an important cause of reduced lung function as inflammation contributes to airflow obstruction in the small airways and lung parenchyma. Even in individuals with mild COPD, inflammation reduces lung function, accelerates decline in lung function overtime, and increases the risk for respiratory exacerbations. Agents that reduce systemic inflammation are hypothesized to decrease the inflammation in the lungs, resulting in improvements in lung function and a decrease in exacerbation frequency. We hypothesize that antidepressants have a beneficial effect on lung function. In addition to having anti-inflammatory properties, antidepressants act upon serotonin, which is integral in central breathing control. The combination of the anti-inflammatory and serotonergic effects may provide users of selective serotonin reuptake inhibitors with a lung function benefit while avoiding the side effects of steroids. This dissertation assesses whether selective serotonin reuptake inhibitors increase concurrent lung function and reduce the risk for respiratory exacerbations. It consists of three parts: a systematic literature review and two analytic papers using large prospective databases. The systematic review of the literature identified limitations concerning the effect of selective serotonin reuptake inhibitors on lung function. Overall, the analytic papers found no support for a beneficial association between selective serotonin reuptake inhibitors and spirometry, dyspnea or pulmonary exacerbations; indeed the association was in the opposite direction as hypothesized. In addition, there was no support for meaningful mediation by inflammatory markers. Further research is needed to determine if selective serotonin reuptake inhibitors have a harmful effect on lung function and pulmonary exacerbations.

description: Let $p$ be a prime number and let $E/\mathbb{Q}$ be an elliptic curve of conductor $p^2$ and odd analytic rank. We prove that the positions of its special points arising from non-split Cartan curves and imaginary quadratic fields where $p$ is inert are encoded in the Fourier coefficients of a Jacobi form of weight $6$ and lattice index of rank $9$, obtaining a result analogous to that of Gross, Kohnen and Zagier.

description: The charge transport of a (Tomonaga-)Luttinger liquid with tunnel barriers exhibits universal scaling: the current-voltage curves measured at various temperatures collapse into a single curve upon rescaling. The exponent characterizing this single curve can be used to extract the strength of electron-electron interaction. Motivated by a recent experiment on InAs nanowires [Sato et al., Phys. Rev. B 99, 155304 (2019)], we theoretically investigate the analogous behavior of a spin-orbit-coupled Luttinger liquid. We find that the scaling exponent differs for different impurity strengths, being weak (disorder potential) or strong (tunnel barriers), and their positions, either in the bulk or near the edge of the wire. For each case we quantify the exponent of the universal scaling and its modification due to the spin-orbit coupling. Our findings serve as a guide in the determination of the interaction strength of quasi-one-dimensional spin-orbit-coupled quantum wires from transport measurements.

description: We give an explicit formula for the arithmetic intersection number of CM cycles on Lubin-Tate spaces for all levels. We prove our formula by formulating the intersection number on the infinite level. Our CM cycles are constructed by choosing two separable quadratic extensions K1, K2/F of non-Archimedean local fields F . Our formula works for all cases, K1 and K2 can be either the same or different, ramify or unramified. As applications, this formula translate the linear Arithmetic Fundamental Lemma (linear AFL) into a comparison of integrals. This formula can also be used to recover Gross and Keating’s result on lifting endomorphism of formal modules.

 Description: Cormus very delicate, formed of large, irregular and loosely anastomosed tubes. No watercollecting tubes are present, and oscula are present throughout all the cormus as simple openings on the tubes.
The wall of the tubes is thin (25 Mm). Its skeleton has no special organization, comprising only equiangular and equiradiate triactines (Fig. 17A). Sometimes, it is possible to find a few tetractines. Actines are straight and cylindrical or slightly conical, with blunt tips.
Found in cryptic habitats, such as under rocks or even on other organisms, protected against light and wave action.
 Remarks: Morphologically similar to another sympatric species, C. conifera. However, the size of the spicules and the shape of the actines (cylindrical in C. cylindractina and conical in C. conifera) serves to distinguish them. These morphological differences were confirmed genetically by electrophoretic analysis, which showed that no gene flow occurred between them (Klautau et al., 1994).

description: We investigate a nonlinear version of coevolving voter models, in which node states and network structure update as a coupled stochastic dynamical process. Most prior work on coevolving voter models has focused on linear update rules with fixed and homogeneous rewiring and adopting probabilities. By contrast, in our nonlinear version, the probability that a node rewires or adopts is a function of how well it "fits in" within its neighborhood. To explore this idea, we incorporate a parameter $σ$ that represents the fraction of neighbors of an updating node that share its opinion state. In an update, with probability $σ^q$ (for some nonlinearity parameter $q$), the updating node rewires; with complementary probability $1-σ^q$, the updating node adopts a new opinion state. We study this mechanism using three rewiring schemes: after an updating node deletes a discordant edge, it then either (1) "rewires-to-random" by choosing a new neighbor in a random process; (2) "rewires-to-same" by choosing a new neighbor in a random process from nodes that share its state; or (3) "rewires-to-none" by not rewiring at all (akin to "unfriending" on social media). We compare our nonlinear coevolving model to several existing linear models, and we find in our model that initial network topology plays a larger role in the dynamics and the choice of rewiring mechanism plays a smaller role. A particularly interesting feature of our model is that, under certain conditions, the opinion state that is held initially by a minority of the nodes can effectively spread to almost every node in a network if the minority nodes view themselves as the majority. In light of this observation, we relate our results to recent work on the majority illusion in social networks.
