title: A study of echinoderm immune agents with a special focus on the sea cucumber Cucumaria frondosa and constructing a comprehensive understanding of its health and well-being
Creators: name: Miller Jobson, Sara
Publisher: name: Memorial University of Newfoundland
Year: 2022

description: Immune responses are among the most well recognized markers of health and well-being in animals; however, they remain far less studied in invertebrate than vertebrate models. Nevertheless, research on invertebrate taxa can provide valuable information on the evolution of innate immunity and subsequently lead to groundbreaking work in vertebrates, including mammals. As deuterostomes possessing remarkable regenerative abilities, echinoderms have held interdisciplinary research interest for decades, particularly in the fields of immunology and developmental biology. Echinoderms are also keystone representatives of marine ecosystems around the globe, and many are the target of exploitation, highlighting the importance of understanding their resilience to environmental and anthropogenic stress. To explore this, I first examined the cellular immune agents of 23 echinoderm species from all five extant classes of this phylum (holothuroids, echinoids, asteroids, ophiuroids, crinoids). I determined that the formation, morphology, and dynamics of coelomocyte aggregates in response to foreign material are fairly conserved across taxa, with some characteristics distinct to each class, including the nature of initial catalysts, pigmentation and the expulsion pathways. Secondly, I examined several bioindicators of stress (cellular, hormonal, and behavioural responses) within the commercial holothuroid Cucumaria frondosa after exposure to stressors common within the fisheries industry (e.g., lower salinities and air exposure at various temperatures). Cucumaria. frondosa displayed measurables responses in all bioindicators that were proportional to the severity of the stress encountered. This research serves both an academic and industry purpose as it further characterizes echinoderm immunity and demonstrates how this information is valuable for stakeholders aiming to sustainably exploit or protect valuable marine resources.

description: We investigate the possibility of spatially homogeneous and inhomogeneous chiral fermion-antifermion condensation and superconducting fermion-fermion pairing in the (1+1)-dimensional model by Chodos {\it et al.} [ Phys. Rev. D 61, 045011 (2000)] generalized to continuous chiral invariance. The consideration is performed at nonzero values of temperature $T$, electric charge chemical potential $μ$ and chiral charge chemical potential $μ_5$. It is shown that at $G_1G_2$ (called duality correspondence). Under the duality transformation the (inhomogeneous) chiral symmetry breaking (CSB) phase is mapped into the (inhomogeneous) superconducting (SC) phase and vice versa. If $G_1=G_2$, then the phase structure of the model is self-dual. Nevertheless, the degeneracy between the CSB and SC phases is possible in this case only when there is a spatial inhomogeneity of condensates.

description: We analyze the brane content and charges in all of the orientifold string theories on space-times of the form E x R^8, where E is an elliptic curve with holomorphic or anti-holomorphic involution. Many of these theories involve "twistings" coming from the B-field and/or sign choices on the orientifold planes. A description of these theories from the point of view of algebraic geometry, using the Legendre normal form, naturally divides them into three groupings. The physical theories within each grouping are related to one another via sequences of T-dualities. Our approach agrees with both previous topological calculations of twisted KR-theory and known physics arguments, and explains how the twistings originate from both a mathematical and a physical perspective.

Predator-prey dynamics on infinite trees: a branching random walk approach

Publisher: name: arXiv

Subjects: subject: Probability (math.PR)
subject: FOS: Mathematics

description: We are interested in predator-prey dynamics on infinite trees, which can informally be seen as particular two-type branching processes where individuals may die (or be infected) only after their parent dies (or is infected). We study two types of such dynamics: the chase-escape process, introduced by Kordzakhia with a variant by Bordenave, and the birth-and-assassination process, introduced by Aldous & Krebs. We exhibit a coupling between these processes and branching random walks starting from a random point and killed at the barrier 0. This sheds new light on the chase-escape and birth-and-assassination processes, which allows us to recover by probabilistic means previously known results and also to obtain new results. For instance, we find the asymptotic behavior of tail of the number of infected individuals in both the subcritical and critical regimes for the chase-escape process, and show that the birth-and-assassination process ends almost surely at criticality.

description: Intermediate states are elusive to many experimental techniques due to their short lifetimes. Here, by performing single-electron alternate charging scanning tunneling microscopy of molecules on insulators, we accessed a charged intermediate state involved in the rapid toggling of individual metal phthalocyanines deposited on NaCl films. By stabilizing the transient species, we reveal how electron injection into the lowest unoccupied molecular orbital leads to a pronounced change in the adsorption geometry, characterized by a different azimuthal orientation. This observation allows clarifying the nature of the toggling process, unveiling the role of transient ionic states involved into fundamental processes occurring at interfaces.
Anti-plane Shear Waves in Layered Composites: Band Structure and Anomalous Wave-refraction

Subjects: subject: Materials Science (cond-mat.mtrl-sci)

description: For oblique anti-plane shear waves in periodic layered elastic composites, it is shown that negative energy refraction is accompanied by positive phase-velocity refraction and positive energy refraction is accompanied by negative phase-velocity refraction, and that, this happens over a broad range of frequencies. The composite's unit cell may consist of any number of layers of any variable mass-density and elastic shear modulus (with large discontinuities). Explicit series expressions for displacement, velocity, strain and stress components, and energy-flux fields are given, and group-velocity vector is calculated. The approach is based on a mixed variational principle where the displacement and stress components are viewed as independent fields subject to arbitrary variation. These fields are hence approximated independently, thereby ensuring the necessary continuity conditions. The resulting computational method yields the composite's frequency band structure and the associated mode shapes, in terms of the wave-vector components for any desired number of frequency bands. The general results are illustrated using a two-phase and a three-phase unit cell with piecewise constant properties. It is shown that on their second frequency pass-bands, only the components of the phase and group velocities normal to the layers are antiparallel, while the components along the layers are parallel. Therefore, both the two-phase and the three-phase composites display negative energy refraction with positive phase-velocity refraction and positive phase-velocity refraction with negative energy refraction, depending on how the composite is interfaced with a homogeneous solid. The presented method is applicable and effective also when some or all of the layers in a unit cell have spatially varying properties.

description: Quadrupole oscillation modes in stars can resonate with incident gravitational waves (GWs), and grow non-linear at the expense of GW energy. Stars near massive black hole binaries (MBHB) can act as GW-charged batteries, cooling radiatively. Mass-loss from these stars can prompt MBHB accretion at near-Eddington rates. GW opacity is independent of amplitude, so distant resonating stars can eclipse GW sources. Absorption by the Sun of GWs from Galactic white dwarf binaries may be detectable with second-generation space-based GW detectors as a shadow within a complex diffraction pattern.

description: Strong modification of spontaneous emission of Eu3+ ions placed in close vicinity to thin and thick gold and silver films was clearly demonstrated in a microscope setup separately for electric and magnetic dipole transitions. We have shown that the magnetic transition was very sensitive to the thickness of the gold substrate and behaved distinctly different from the electric transition. The observations were described theoretically based on the dyadic Green's function approach for layered media and explained through modified image models for the near and far-field emissions. We established that there exists a "near-field event horizon", which demarcates the distance from the metal at which the dipole emission is taken up exclusively in the near field.

description: We study complex structure deformations of special Lagrangian cycles associated to fractional D-branes at $\mathbb{Z}_2$ singularities in Type II/$Ω\mathcal{R}$ orientifold models. By means of solving hypersurface constraints, we show how to compute the volumes of the most simple D-brane configurations. These volumes are given as a function of the deformation parameters depending on the D-brane position relative to the smoothed out singularity. We observe which cycles keep the special Lagrangian property in various deformation scenarios and what orientifold involutions are allowed. As expected, the volume and thus the tree level value of the gauge coupling hardly change for D-branes not wrapping the exceptional cycle on the deformed singularity, whereas the volume of D-branes passing through the singularity depends on the deformation parameter by some power law.

title: How property developers make decisions: Dublin 2010 – 2020
Creators: name: Fallon, Eimear
Publisher: name: University of Glasgow
Year: 2022

description: Property developers make crucial decisions that determine the shape and feel of our towns and cities, yet there is little consensus on how these decisions are made. This research asks how property developers make real-life decisions in a development process that is widely acknowledged to be complex and uncertain. It contributes to the growing body of research on developers that rejects the simplistic economic understanding of developers as predictable rational actors. To do this a new conceptual framework is developed that incorporates both the broader social and psychological dimensions of how decisions are made. The research design takes the form of a case study so that context can be considered because property developers’ actions and decisions are known to be embedded into a prevailing local institutional context – Dublin from 2010 to 2020. This research argues that public sector relationships are used to influence, bypass and reshape policies in an attempt to reduce uncertainty. On the other hand, private sector relationships appear more nuanced where those relationships that secure resources such as equity funding are often deeply personal and trusting, and those that deliver market rich information depend on developers being more widely connected in social and loose networks. It is clear that it is the entrepreneurial characteristics such as creativity, drive and organisation skills that define the developer’s role in the development process. The broader psychological dimensions of the conceptual framework used in this research reveals that longer-term decisions with more uncertain outcomes are arrived at through intuitive, emotionally charged psychological decision processes. The behavioural economics literature foregrounds the extensive use of heuristics and points to the clear dangers that can result from relying on this type of decision making. However, this research argues that in complex uncertain decision environments where the decision outcome is longer term, property developers plumb the deep resources of their experience gained through successive development cycles. By doing this a set of patterns, or mental short-cuts is recognised that through habitual use has proved successful in the past. Finally, this research throws light on the behaviour that results from considering decision making through this new conceptual framework. It finds that experienced place-based local property developers pay greater attention to deep trusting relationships to achieve their objectives which is distinguished from institutional and novice developers. By differentiating between experienced and novice developers, this study developed the old institutionalists’ ideas of the power of intuition and the importance of developing habit through experience.

description: The parameter space of the phenomenological MSSM (pMSSM) is explored by means of Markov Chain Monte Charlo (MCMC) methods, taking into account the latest LHC results on the Higgs signal at 125 GeV in addition to relevant low-energy observables and LEP constraints. We use a Bayesian approach to derive posterior densities for the parameters and observables of interests. We find in particular that the Higgs measurements have a significant impact on the parameters mu and tan beta due to radiative corrections to the bottom Yukawa coupling. We show moreover the impact of the most recent dark matter measurements on the probability distributions, and we discuss prospects for the next run of the LHC at 13-14 TeV.

For each update rule, the largest mean consensus time scales as O(N^3), where N is the number of nodes in the network.

description: In view of the continuous theoretical efforts aimed at an accurate microscopic description of the strongly correlated transition metal oxides and related materials, we show that with continuum quantum Monte Carlo (QMC) calculations it is possible to obtain the value of the spin superexchange coupling constant of a copper oxide in a quantitatively excellent agreement with experiment. The variational nature of the QMC total energy allows us to identify the best trial wave function out of the available pool of wave functions, which makes the approach essentially free from adjustable parameters and thus truly ab initio. The present results on magnetic interactions suggest that QMC is capable of accurately describing ground state properties of strongly correlated materials.

description: Indirect constraints on the total Higgs width $Γ_h$ from correlating Higgs signal strengths with cross section measurements in the off-shell region for $p(g)p(g)\to 4\ell$ production have received considerable attention recently, and the CMS collaboration have published a first measurement. We revisit this analysis from a new physics and unitarity constraints perspective and conclude that limits on $Γ_h$ obtained in this fashion are not reliable unless we make model-specific assumptions, which cannot be justified at the current stage of the LHC programme. Relaxing the $Γ_h$ interpretation, we discuss the merits of high invariant mass cross section measurements in the context of Higgs CP analyses, higher dimensional operator testing, and resolved new physics in the light of electroweak precision constraints beyond effective theory limitations. Furthermore, we show that a rather model-independent LHC constraint can be obtained from adapting the $gg\to 4\ell$ analysis to the weak boson fusion channels at lower statistical yield.

description: The use of natural inert dusts against storage insect pests is increasing recently, as an alternative to conventional insecticides. Laboratory study was carried out to evaluate the contact effect of three inert dusts, diatomaceous earth (DE), kaoline (KA) and vermiculite (VE), at rates 5, 7.5, 10, 15 and 20 gm-2, against adults of Sitophilus oryzae (L.) and larvae of Plodia interpunctella (Hubner). Insect mortality was evaluated 1, 2, 3 and 7 days after the exposure. Insect mortality varied depending on the species, concentrations and exposure periods. The DE and KA caused 86.7-98% mortality of S. oryzae after 2 days of exposure at the highest rates, while at 5 and 7.5 gm-2, 100% mortality was achieved only after 7 days. The highest rates of inert dusts caused 42-50% (DE) and 60-75% (KA) mortality of P. interpunctella larvae only after 7days. The mortality of moths increased gradually with the concentration and 100% was achieved 3 days after the contact with DE and KA (10, 15 and 20 g m-2). However, inert dusts induced faster pupation of P. interpunctella, while adult emergence was reduced and adults had smaller body-sizes, compared to control. The VE caused relatively low mortalities (7-11% of S. oryzae adults and 5-8% of P. interpunctella larvae) at all tested rates during the entire experiment. Our results have shown good insecticidal effect of DE and KA against S. oryzae and P. interpunctella at 10, 15 and 20 gm-2. These products could therefore be used by small-scale farmers to protect stored grains against insect pest infestation.

Preparing for the future of direct imaging exoplanets

Publisher: name: Zenodo

description: Very little is known about giant planets and brown dwarfs at an orbital separation great than 5 AU. And yet, these are important puzzle pieces needed for constraining the uncertainties that exist in giant planet formation and evolutionary models that are plagued by a lack of observational constraints. In order to observationally probe this mass-separation parameter space, direct imaging is necessary but faces the difficulty of low detection efficiency. To utilize the power of direct imaging, pre-selecting companion candidates with long-period radial velocities, coupled with proper anomalies from Hipparcos and Gaia, provide a powerful tool to hunt for the most promising candidates for direct imaging. Not only does this increase the detection efficiency, but this wealth of information removes the degeneracy of unknown orbital parameters, like the inclination, leading to derived dynamical masses which can serve as benchmark objects to test models of formation and evolution. With upcoming missions like JWST and Roman, as well as ground-based facilities like the ELT, observing time is valuable and the strategy of direct imaging needs to be re-defined to pre-select targets. Looking further ahead, perfecting these strategies will be necessary as we look toward a large IR/O/UV mission, as recommended by the Astro 2020 decadal survey report, to pinpoint the location of terrestrial planets amenable to direct imaging. I present the ongoing work towards creating a tool to use this information to select candidates for direct imaging with upcoming and future instruments. Ultimately this will lead us to a catalog of benchmark objects that can be used to test models of planet formation and evolution.

description: Light-emitting diodes are of importance for lighting, displays, optical interconnects, logic and sensors. Hence the development of new systems that allow improvements in their efficiency, spectral properties, compactness and integrability could have significant ramifications. Monolayer transition metal dichalcogenides have recently emerged as interesting candidates for optoelectronic applications due to their unique optical properties. Electroluminescence has already been observed from monolayer MoS2 devices. However, the electroluminescence efficiency was low and the linewidth broad due both to the poor optical quality of MoS2 and to ineffective contacts. Here, we report electroluminescence from lateral p-n junctions in monolayer WSe2 induced electrostatically using a thin boron nitride support as a dielectric layer with multiple metal gates beneath. This structure allows effective injection of electrons and holes, and combined with the high optical quality of WSe2 it yields bright electroluminescence with 1000 times smaller injection current and 10 times smaller linewidth than in MoS2. Furthermore, by increasing the injection bias we can tune the electroluminescence between regimes of impurity-bound, charged, and neutral excitons. This system has the required ingredients for new kinds of optoelectronic devices such as spin- and valley-polarized light-emitting diodes, on-chip lasers, and two-dimensional electro-optic modulators.

description: We investigate charge quantization in the Standard Model (SM) through a $\mathbb{CP}^2$ nonlinear sigma model (NLSM), $SU(3)_G/(SU(2)_H \times U(1)_H)$, and a $\mathbb{CP}^3$ model, $SU(4)_G/(SU(3)_H \times U(1)_H)$. We also generalize to any $\mathbb{CP}^k$ model. Charge quantization follows from the consistency and dynamics of the NLSM, without a monopole or Grand Unified Theory, as shown in our earlier work on the $\mathbb{CP}^1$ model (arXiv:1309.0692). We find that representations of the matter fields under the unbroken non-abelian subgroup dictate their charge quantization under the $U(1)_H$ factor. In the $\mathbb{CP}^2$ model the unbroken group is identified with the weak and hypercharge groups of the SM, and the Nambu-Goldstone boson (NGB) has the quantum numbers of a SM Higgs. There is the intriguing possibility of a connection with the vanishing of the Higgs self-coupling at the Planck scale. Interestingly, with some minor assumptions (no vector-like matter and minimal representations) and starting with a single quark doublet, anomaly cancellation requires the matter structure of a generation in the SM. Similar analysis holds in the $\mathbb{CP}^3$ model, with the unbroken group identified with QCD and hypercharge, and the NGB having the up quark as a partner in a supersymmetric model. This can motivate solving the strong CP problem with a vanishing up quark mass.

description: By considering semi-inclusive deep-inelastic scattering and the (complementary) $q_T$-spectrum for Drell-Yan lepton pair production we derive the QCD evolution for all the leading-twist transverse momentum dependent distribution and fragmentation functions. We argue that all of those functions evolve with $Q^2$ following a \emph{single} evolution kernel. This kernel is independent of the underlying kinematics and it is also spin-independent. Those features hold, in impact parameter space, to all values of $b_T$. The evolution kernel presented has all of its large logarithms resummed up next-to-next-to leading logarithmic accuracy, which is the highest possible accuracy given existing perturbative calculations. As a study case we apply this kernel to investigate the evolution of Collins function, one of the ingredients that have attracted recently much attention within the phenomenological studies of spin asymmetries. Our analysis can be readily implemented to revisit previously obtained fits that involve data at different scales for other spin-dependent functions. Such improved fits are important to get better predictions --with the correct evolution kernel-- for certain upcoming experiments aiming to measure Sivers function, Collins function, transversity and other spin-dependent functions as well.

description: Pulses have 20-27% proteins which is 2- 3 times higher than traditional cereals. These constitute the main source of proteins for developing countries, like India where per capita consumption of the animal protein is low, thus they are rightly considered the poor man’s meat. India is largest pulse consumer, importer and producer country of the world occupying an area of 228.47 lakh hectares with the production of 17380 million tones every year. With the United Nations declaration of 2016 as International Year of Pulses to replace the social evil of malnutrition by legume, the research pertaining to the biology and bio intensive management of bruchids pests has become increasingly important. Therefore, laboratory bioassay of essential oils which are regarded as “Green Chemicals” extracted from Zanthoxylum armatum DC., Rabdosia rugosa Wall. ex Benth, Artemisia maritima Linn. and Colebrookea oppositifolia Sm. by hydro distillation was carried out against Callosobruchus analis (F.) to evaluate biopesticidal potential in terms of oviposition and progeny deterrence and ovicidal activities. There was a significant difference in the number of eggs laid on treated and control sets and among the different treatments of essential oils. Z. armatum at 100 µl/ml allowed the bruchid to lay only 19.15±3.6 eggs as compared to 82.35±4.5 in control and proved to be most effective treatment with 76.74% oviposition deterrence. R. rugosa and A. maritima oil were found most effective in reducing the egg hatchability to 48.00±3.2 and 49.52±2.2% respectively at a lowest dose of 10 µl/ml. Egg hatching inhibition percentage increased with an increase in concentration of all the treatments. R. rugosa oil at 100 µl/ml proved to be most effective in reducing the adult emergence with 85.48% progeny deterrence followed by A. maritima showing 81.67% deterrence. All the tested essential oils revealed a wide range of bioactivities against the bruchid pest.

title: Exploring anxiety disorders during pregnancy planning: a qualitative study of women’s experiences in Nova Scotia
Creators: name: Crawford, Ashley
Publisher: name: Memorial University of Newfoundland

description: Anxiety disorders are common in North America, especially among women of reproductive age. However, there is very little research examining women’s perspectives of pregnancy planning. The purpose of this modified grounded theory master’s thesis is to understand the factors that shape the pregnancy planning decisions of women with anxiety disorders in Nova Scotia. Qualitative semi-structured interviews (N=8) were conducted, and three themes were deduced. First, undertaking a pregnancy in the presence of an anxiety disorder is complex because of increased personal needs – specifically, choosing between anxiety disorder management and social expectations. Second, physicians may not all provide sufficient information about the impact of anxiety disorders during pregnancy. Third, which was an unexpected observation, women perceived their anxiety disorder as being associated with their fertility. Recommendations emerging from this study are: (1) health providers should discuss with women who have anxiety disorders the challenges associated with undertaking pregnancy; (2) information about pregnancy planning should be more available for women with anxiety disorders as it would help them make informed decisions; (3) women with anxiety disorders should be encouraged to consider midwives as care providers because midwives may provide the best support during pregnancy planning and throughout pregnancy.
Electrochemical Strain Microscopy of Silica Glasses

description: Piezoresponse Force Microscopy (PFM) and Electrochemical Strain Microscopy (ESM) are two related techniques that have had considerable success in nano-scale probing of functional material properties. Both measure the strain of the sample in response to a localized electric field beneath a sharp conductive tip. In this work, a collection of commercially available glass samples were measured with a variety of Si cantilevers coated with different conductive metals. In some cases, these glasses showed significant hysteresis loops, similar in appearance to those measured on ferroelectric materials with spontaneous permanent electric dipoles. The magnitude of the electrochemical strain and hysteresis correlated well with the molar percentage of sodium in the glass material, with high sodium (soda-lime) glass showing large hysteresis and fused silica (pure SiO2) showing essentially no hysteresis. The elephant-ear shape of the hysteresis loops correlated well with it originating from relaxation behavior, an interpretation verified by observing the temperature dependent relaxation of the ESM response. Cation mobility in a disordered glass should have a low diffusion constant. To evaluate this diffusion constant, the temperature of the glass was varied between room temperature and 200C. Vanishing hysteresis as the temperature increased was associated with a decrease in the relaxation time of the electrochemical response. The hysteretic behavior changed drastically in this temperature range, consistent with bound surface water playing a large role in the relaxation. This demonstrates the ability of ESM to differentiate cationic concentrations in a range of silica glasses. In addition, since glass is a common sample substrate for, this provides some clear guidance for avoiding unwanted substrate crosstalk effects in piezoresponse and electrochemical strain response measurements.

description: Successful storage of harvest is a matter of utmost importance in the Sudano-Guinean agro-ecological zone where intense cultivation takes place only once a year. Poor and rudimentary drying/storage methods, high relative humidity as well as inaccessibility to the chemical pesticides leave stored maize at the mercy of insect and fungal attack. Insect attack favours secondary attack by fungi; both leading to a fall in the nutritional, sanitary and organoleptic qualities of the stored maize. Thus, poor peasant farmers are left with the choice of locally available botanicals as alternatives to chemical pesticides. It is against this backdrop that this study seeks to determine the insecticidal efficacy of essential oils from the leaves of Chenopodium ambrosioides and Cupressus sempervirens together with their 50/50 binary combination against the maize weevil, Sitophilus zeamais, and the fungi: Rhizopus stolonifer and Aspergillus flavus on stored maize. Insect mortality and progeny inhibition and the inhibition of fungal invasion were evaluated. Pesticidal activities of both essential oils increased with ascending dose of application. 200 µL/kg of the binary combination caused 100% mortality within 14 days and it completely inhibited progeny production in the weevil. The mixture of the two oils showed additive effects against the weevils and fungi. The two essential oils in isolation significantly inhibited fungal spore invasion in 21 days of storage although A. flavus was less susceptible than R. stolonifer. Therefore both plants could provide active botanical pesticides against S. zeamais and fungal pests in stored maize.

description: In this paper we construct a new difference analog of the Caputo fractional derivative (called the $L2$-$1_σ$ formula). The basic properties of this difference operator are investigated and on its basis some difference schemes generating approximations of the second and forth order in space and the second order in time for the time fractional diffusion equation with variable coefficients are considered. Stability of the suggested schemes and also their convergence in the grid $L_2$ - norm with the rate equal to the order of the approximation error are proved. The obtained results are supported by the numerical calculations carried out for some test problems.
