description: Cyanobacterial blooms pose health risks to recreational water users. In New Zealand, cyanobacteria biovolumes are used to assess risk, but analyses can be time-consuming and costly. In this study, measurements from a handheld phycocyanin sensor (Cyclops-7, Turner Designs, USA) were compared with biovolumes from five lakes and a river in the Rotorua district over two years (2016, n = 121; 2017, n = 63). In the laboratory, relationships between sensor phycocyanin and biovolumes were assessed for four species to investigate precision and detection limits. The relationship between phycocyanin and biovolume was generally weak (<R2 = 0.4) and varied among lakes and years, except at high biovolumes. Precision and detection limits differed among species. The biovolume detection limit derived from relationships with phycocyanin was above alert level thresholds for two of the four cyanobacteria species assessed. The phycocyanin sensor that was tested likely has limited utility but may be useful for on-site confirmation of exceedances of alert level thresholds corresponding to when authorities should immediately issue health warnings.
Physiological and pathophysiological regulation of the ryanodine receptor in skeletal muscle

description: Ryanodine receptor calcium release channels are essential for skeletal muscle contraction, as they mediate the release of calcium ions from intracellular stores into the cytosol. The data presented in this dissertation demonstrate the evolutionarily conserved mechanisms of skeletal muscle ryanodine receptor regulation in the physiological and pathophysiological states.
      Adrenergic stimulation causes increased skeletal muscle force, however, despite the well-established role of this physiological response, the molecular mechanism is not known. Here we present a mechanism whereby phosphorylation of a single amino acid on the ryanodine receptor is a key signal in the physiological stress-induced inotropic response in mouse skeletal muscle. Therefore acute post-translational modifications of ryanodine receptor channels are important for healthy muscle contraction. Conversely, chronic stress-induced post-translational modifications result in poorly functioning murine ryanodine receptor channels that contribute to skeletal muscle dysfunction in age-dependent skeletal muscle weakness and Muscular Dystrophies.
      Finally, we present data that demonstrates striking evolutionary conservation in ryanodine receptor regulation in the physiological and pathophysiological states between mice and C. elegans. This work has broad implications for understanding the underlying mechanisms of skeletal muscle contraction and important disorders that affect human health. Furthermore, this works presents ryanodine receptor channels as a viable therapeutic target for age-related skeletal muscle weakness, Muscular Dystrophies, and also implicates C. elegans as a potential model system in which to test future therapeutic targets.

description: Suppose there are two framed links in a compact, connected 3-manifold (possibly with boundary, or non-orientable) such that the associated 3-manifolds obtained by surgery are homeomorphic (relative to their common boundary, if there is one.) How are the links related? Kirby's theorem gives the answer when the manifold is S^3, and Fenn and Rourke extended it to the case of any closed orientable 3-manifold, or twisted S^1 cross S^2. The purpose of this note is to give the answer in the general case, using only minor modifications of Kirby's original proof.

description: While no-hair theorems forbid isolated black holes from possessing permanent moments beyond their mass, electric charge, and angular momentum, research over the past two decades has demonstrated that a black hole interacting with a time-dependent background scalar field will gain an induced scalar charge. In this paper, we study this phenomenon from an effective field theory (EFT) perspective. We employ a novel approach to constructing the effective point-particle action for the black hole by integrating out a set of composite operators localized on its worldline. This procedure, carried out using the in-in formalism, enables a systematic accounting of both conservative and dissipative effects associated with the black hole's horizon at the level of the action. We show that the induced scalar charge is inextricably linked to accretion of the background environment, as both effects stem from the same parent term in the effective action. The charge, in turn, implies that a black hole can radiate scalar waves and will also experience a "fifth force." Our EFT correctly reproduces known results in the literature for massless scalars, but now also generalizes to massive real scalar fields, allowing us to consider a wider range of scenarios of astrophysical interest. As an example, we use our EFT to study the early inspiral of a black hole binary embedded in a fuzzy dark matter halo.

description: Measurement error and misclassification arise commonly in various data collection processes. It is well-known that ignoring these features in the data analysis usually leads to biased inference. With the generalized linear model setting, Yi et al. [Functional and structural methods with mixed measurement error and misclassification in covariates. J Am Stat Assoc. 2015;110:681–696] developed inference methods to adjust for the effects of measurement error in continuous covariates and misclassification in discrete covariates simultaneously for the scenario where validation data are available. The augmented simulation-extrapolation (SIMEX) approach they developed generalizes the usual SIMEX method which is only applicable to handle continuous error-prone covariates. To implement this method, we develop an R package, augSIMEX, for public use. Simulation studies are conducted to illustrate the use of the algorithm. This package is available at CRAN.

description: We provide the complete set of global solutions of viscous transonic flows (VTFs) around black holes and neutron stars. These solutions describe the optically thick and optically thin flows from the horizon of the black hole or from the neutron star surface to the location where the flow joins with a Keplerian disk. We study the nature of the multiple sonic points as functions of advection, rotation, viscosity, heating and cooling. Stable shock waves, which join two transonic solutions, are found to be present in a large region of the parameter space. We classify the solutions in terms of whether or not the flow can have a standing shock wave. We find no new topology of solutions other than what are observed in our previous studies of isothermal VTFs. We particularly stress the importance of the boundary conditions and argue that we have the most complete solution of accretion and winds around black holes and neutron stars.

description: In a process called parametric down-conversion, a dc-biased Josephson junction coupled to two microwave resonators emits photon pairs when the Josephson frequency matches the sum of the two resonance frequencies. Recent experiments have shown that such a setup permits analyzing the correlation of the radiation. Motivated by these results, we study theoretically the full counting statistics of a non-degenerate parametric oscillator below the threshold of instability. Furthermore, we analyze the second-order coherences of the radiation and discuss thermal effects on the radiation statistics. We provide results for the driving strength at which the Cauchy-Schwarz inequality is most strongly violated. Additionally, we study the impact of asymmetry in the linewidth of the modes---a distinctive property of the non-degenerate resonance effect. In particular, we find that the radiation from the mode with the larger linewidth preferably takes the total detuning, while the other mode emits photons at its resonance frequency.

Unusual properties on magnetization, entropy and susceptibility emerge, as a consequence of nonextensivity. We further show that the nonextensive approach can be relevant to the field of manganites, materials which exhibit long-range interactions and fractality, two basic ingredients for nonextensivity. Our results are in qualitative agreement to experimental data in La$_{0.67}$Ca$_{0.33}$MnO$_3$ and Pr$_{0.5}$Ca$_{0.5}$Mn$_{0.95}$Ga$_{0.05}$O$_3$ manganites.

description: A classical 6j-symbol is a real number which can be associated to a labelling of the six edges of a tetrahedron by irreducible representations of SU(2). This abstract association is traditionally used simply to express the symmetry of the 6j-symbol, which is a purely algebraic object; however, it has a deeper geometric significance. Ponzano and Regge, expanding on work of Wigner, gave a striking (but unproved) asymptotic formula relating the value of the 6j-symbol, when the dimensions of the representations are large, to the volume of an honest Euclidean tetrahedron whose edge lengths are these dimensions. The goal of this paper is to prove and explain this formula by using geometric quantization. A surprising spin-off is that a generic Euclidean tetrahedron gives rise to a family of twelve scissors-congruent but non-congruent tetrahedra.

The typology of companions’ contribution in Auhud battle based on The Quran and historical resources

name: Far, Fatemeh Motahary
Publisher: name: figshare
Year: 2020
Subjects: History

description: Auhud, one of the significant battles in the prophet era, had a strong influence on Muslim destiny. Initially victorious, the battle ended up with defeat at the part of Muslims in spite of enemy desertion. Having various contributions of companions during the battle, some companions fought sincerely for the sake of the prophet and his mission however, some did not prove so. Their effort so could be considered as inefficient support as they escaped from the field and failed to resist. The Quranic and historical resources approach to this event may vary so this research intends to recognize the type of contributions made in the battle. The method applied in this research is qualitative typology. According to the statistics, from 27 verses (Ayat) about Auhud Battle only 30% would bear the index of “full supporters” whereas the rest of 70% fall for “semi or non supporters” index. Interestingly, the historical resources, willing to introduce the majority of companions as full supporters, ignore the characteristics of two other indicia upon them. Therefore, the Quranic critical approach to the passive contribution of majority of companions in the battle shows obvious contradiction towards the historical resource analysis. In fact, the verses address to the companions who were negligent in the field of the battle and their effort has considered as insufficient and inefficient to support the prophet.

description: We develop the canonical quantization of a midisuperspace model which contains, as a subspace, a minisuperspace constituted of a Friedman-Lema\^ıtre-Robertson-Walker Universe filled with homogeneous scalar and dust fields, where the sign of the intrinsic curvature of the spacelike hypersurfaces of homogeneity is not specified, allowing the study of topology change in these hypersurfaces. We solve the Wheeler-DeWitt equation of the midisuperspace model restricted to this minisuperspace subspace in the semi-classical approximation. Adopting the conditional probability interpretation, we find that some of the solutions present change of topology of the homogeneous hypersurfaces. However, this result depends crucially on the interpretation we adopt: using the usual probabilistic interpretation, we find selection rules which forbid some of these topology changes.

description: VLBI and JVLA observations revealed that GW170817 involved a narrow jet ($ θ_j \approx 4^\circ $) that dominated the afterglow peak at our viewing angle, $ θ_{\rm obs} \approx 20^\circ $. This implies that at the time of the afterglow peak, the observed signal behaved like an afterglow of a top-hat jet seen at $ θ_{\rm obs} \gg θ_j $, and it can be modeled by analytic expressions that describe such jets. We use a set of numerical simulations to calibrate these analytic relations and obtain generic equations for the peak time and flux of such an afterglow as seen from various observing angles. Using the calibrated equations and the estimated parameters of GW170817, we estimate the detectability of afterglows from future double neutron star mergers during the Advanced LIGO/Virgo observation run O3. GW170817 took place at a relatively low-density environment. Afterglows of similar events will be detectable only at small viewing angles, $ θ_{\rm obs} \lesssim 20^\circ $, and only $\sim 20\% $ of the GW detections of these events will be accompanied by a detectable afterglow. At higher densities, more typical to sGRB sites, up to $ 70\% $ of the GW detections are expected to be followed by a detectable afterglow, typically at $ θ_{\rm obs} \sim 30^\circ $. We also provide the latest time one should expect an afterglow detection. We find that for typical parameters, if the jet emission had not been detected within about a year after the merger, it is unlikely to be ever detected.

description: In this paper, we revisit in detail the effects of primordial magnetic fields on big bang nucleosynthesis (BBN) including a discussion of the magnetic field geometry and the anomalous magnetic moment. The presence of magnetic fields affects BBN by (1) increasing the weak reaction rates; (2) increasing the electron density due to changes to the electron phase space; and (3) by increasing the expansion rate of the universe, due both to the magnetic field energy density and to the modified electron energy density. Of the effects considered, the increase in the expansion rate due to the magnetic field energy is the most significant for the interests of BBN. The allowed magnetic field intensity at the end of nucleosynthesis (0.01 MeV) is about $2 \times 10^{9}$G and corresponds to an upper limit on the magnetic field energy density of about 28\% of the neutrino energy density ($ρ_B \le 0.28 ρ_ν$).

description: We consider a two-component Bose gas in two dimensions at low temperature with short-range repulsive interaction. In the coexistence phase where both components are superfluid, inter-species interactions induce a nondissipative drag between the two superfluid flows (Andreev-Bashkin effect). We show that this behavior leads to a modification of the usual Berezinskii-Kosterlitz-Thouless (BKT) transition in two dimensions. We extend the renormalization of the superfluid densities at finite temperature using the renormalization group approach and find that the vortices of one component have a large influence on the superfluid properties of the other, mediated by the nondissipative drag. The extended BKT flow equations indicate that the occurrence of the vortex unbinding transition in one of the components can induce the breakdown of superfluidity also in the other, leading to a locking phenomenon for the critical temperatures of the two gases.

Charge and spin-specific local integrals of motion in a disordered Hubbard model

description: While many-body localization has primarily been studied in systems with a single local degree of freedom, experimental studies of many-body localization in cold atom systems motivate exploration of the disordered Hubbard model. With two coupled local degrees of freedom it is natural to ask how localization in spin relates to disorder in charge and vice versa. Most prior work has addressed disorder in only one of these sectors and often has not used measures of localization which distinguish between charge and spin. Here we explore localization in the Hubbard model with a wide range of independent values of charge and spin disorder, using measures of localization based on charge and spin-specific integrals of motion. Our results demonstrate symmetry between the response of the spin to charge disorder and vice versa, and we find very weak disorder in one channel, so long as the disorder in the other channel is sufficiently strong, results in localization in both channels. The strength of disorder required in the less disordered channel declines as the system size increases. Further, the weaker the disorder in the less-disordered channel, the longer the time scale at which localization appears in the dynamics of this degree of freedom.

description: The Strategic Advisory Panel on Selenium Management is a broadly-based group of experts who have achieved success via independent, transparent stakeholder engagement with full collaboration across diverse disciplines. The Panel was formed in January 2010 to assist Teck Coal and its stakeholders in finding a sustainable approach to the management of selenium released from Teck‟s metallurgical coal mines in south-eastern BC and north-western Alberta. The Panel‟s Charter stipulated that the Panel would operate independently and would release a strategic plan for the management of selenium within six months. While part of the Panel‟s work was highly technical, an equally important activity was active engagement with stakeholders. Selenium is a controversial topic with significant technical uncertainties, and often with strongly held views by potentially affected people (concerning their health or effects on ecosystem services). Past attempts to deal with these uncertainties had not succeeded in producing an acceptable plan for managing selenium loadings to the watershed, which were steadily increasing. Trust among stakeholders was low. The Panel used one-on-one meetings, workshops, site visits, and community meetings to reach out to Teck personnel, regulators, First Nations, NGOs, elected officials, and representatives of key stakeholder groups such as fly fishers. The Panel‟s engagement activities, combined with the release of the strategic plan report without prior review by stakeholders (including Teck) produced a substantial increase in trust and engagement. The rapid acceptance of the report by the CEO of Teck Coal added to that trust. The involvement of stakeholders has continued into the implementation phase, which includes management of selenium at legacy waste dumps, incorporation of new operating procedures at active mines, inclusion of alternative mine and waste management practices for proposed expansions and new mines, and Teck‟s continued engagement with a community-based watershed-health advocacy group. The continued engagement of stakeholders is an integral part of Teck‟s commitment to sustainable mining. The Panel‟s experience shows that independent advisory panels can be an effective catalyst for trust-building, especially if their activities truly are governed by sustainability principles.
Pica in Pregnancy Among Mexican-Born Women: Effects of Magnesium Carbonate Ingestion

Subjects: subject: Psychology
subject: FOS: Psychology

description: Pica is a condition characterized by the repetitive ingestion of non-food items for more
than one month. Due to the bizarre nature of this condition, pica has been studied and theorized
over for many years. It is most often found among children, the mentally ill, and pregnant
women. In regards to pica during pregnancy, the literature on pica covers the obviously
detrimental effects on mothers of consuming clearly harmful substances. Magnesium carbonate,
more commonly referred to as chalk, is one of the most frequently ingested substances by
women during pregnancy. While often found within common brands of antacids, magnesium
carbonate is frequently sold in block form and advertised as edible products within certain
regions of the United States and Mexico. The immediate effects of chalk ingestion upon a
pregnant mother has been explored to some extent, but not to the degree in which the effects of
clearly harmful substances have been examined. A large gap is found in the literature when
considering the effects of more benign substances such as magnesium carbonate not only on the
mother, but the developing fetus as well. More specifically, the current literature fails to address
the question of whether magnesium carbonate ingestion during pregnancy could carry enduring,
long-term effects for a fetus post-birth that could detrimentally influence later cognitive, motor,
and/or behavioral development.

description: In a complementary article, we exploited algebraic properties of Maxwell's equations and fundamental principles such as electromagnetic reciprocity and passivity, to derive fundamental limits to radiative heat transfer applicable in near- through far-field regimes. The limits depend on the choice of material susceptibilities and bounding surfaces enclosing arbitrarily shaped objects. In this article, we apply these bounds to two different geometric configurations of interest, namely dipolar particles or extended structures of infinite area in the near field of one another, and compare these predictions to prior limits. We find that while near-field radiative heat transfer between dipolar particles can saturate purely geometric "Landauer" limits, bounds on extended structures cannot, instead growing much more slowly with respect to a material response figure of merit, an "inverse resistivity" for metals, due to the deleterious effects of multiple scattering; nanostructuring is unable to overcome these limits, which can be practically reached by planar media at the surface polariton condition.

description: This work takes us a step closer to realizing personalized medicine, complementing empirical and heuristic way in which clinicians typically work. This thesis presents mechanistic models of physiology. These models, given continuous signals from a patient, can be fine-tuned via parameter estimation methods so that the model's outputs match the patient's. We thus obtain a virtual patient mimicking the patient at hand. Therapeutic scenarios can then be applied and optimal diagnosis and therapy can thus be attained. As such, personalized medicine can then be achieved without resorting to costly genetics.
      In particular we have developed a novel comprehensive mathematical model of the cardiopulmonary system that includes cardiovascular circulation, respiratory mechanics, tissue and alveolar gas exchange, as well as short-term neural control. Validity of the model was proven by the excellent agreement with real patient data, under normo-physiological as well as hypercapnic and hypoxic conditions, taken from literature.
      As a concrete example, a submodel of the lung mechanics was fine-tuned using real patient data and personalized respiratory parameters (resistance, R_rs, and compliance, C_rs) were estimated continually. This allows us to compute the patient's effort (Work of Breathing), continuously and more importantly noninvasively.
      Finally, the use of Bayesian estimation techniques, which allow incorporation of population studies and prior information about model's parameters, was proposed in the contest of patient-specific physiological models. A Bayesian Maximum a Posteriori Probability (MAP) estimator was implemented and applied to a case-study of respiratory mechanics. Its superiority against the classical Least Squares method was proven in data-poor conditions using both simulated and real animal data.
      This thesis can serve as a platform for a plethora of applications for cardiopulmonary personalized medicine.

Metalepta Baly, 1861: 205 (type species Metalepta tuberculata Baly, 1861, by original designation).
Remarks
This genus includes three described species, distributed in Ecuador and Peru. See Fig. 50 for a habitus illustration. Beenen (2013) reported the front coxal cavities to be posteriorly closed. However, they appear to be open in material we have examined. Perhaps, this character is variable among the species. Regarding this genus, we have not used this character in the following key. The placement in the principally Old World section Apophyliites is quite doubtful.

description: Als Schutzelemente für geneigte Küstenschutzbauwerke werden patentierte Hohlformkörper vorgeschlagen. Durch die böschungsparallel gebildete Hohlstruktur wird die Wechselwirkung zwischen der am Bauwerk partiell stehenden Welle und der Waschbewegung auf der Böschung im Sinne geringerer Wellenbelastung günstig beeinflusst. Durch die Verwendung von Hohldeckwerken können Küstenschutzbauwerke niedriger und mit steilerer seeseitiger Neigung ausgeführt werden. Die partielle Reflexion wird maßgeblich durch die zwischen einfallender und reflektierter Welle auftretende Phasendifferenz bestimmt. Zudem wird eine selektive Reflexion definiert.
description: A proposal is made for a design of the cover layers of nonvertical coastal structures (such as seawalls, revetments, groins, jetties and breakwaters) by applying hollow structural elements. The re-spective cavity is oriented parallel to the slope face and permits the inside washing movement of the swash produced by breakers. The purpose of the new designed structure is to influence interaction processes between the near surface water particle kinematics of incomplete standing waves in front of the structure and the swash movement on the slope face. The effectiveness of such a working principle is traced back to a selective reflection effect, real-ised by model investigations. Applying this new type of elements, slopes can be designed steeper and/or crown heights lower.
Some Physical Consequences of Abrupt Changes in the Multipole Moments of a Gravitating Body

description: The Barrabès-Israel theory of light-like shells in General Relativity is used to show explicitly that in general a light-like shell is accompanied by an impulsive gravitational wave. The gravitational wave is identified by its Petrov Type N contribution to a Dirac delta-function term in the Weyl conformal curvature tensor (with the delta-function singular on the null hypersurface history of the wave and shell). An example is described in which an asymptotically flat static vacuum Weyl space-time experiences a sudden change across a null hypersurface in the multipole moments of its isolated axially symmetric source. A light-like shell and an impulsive gravitational wave are identified, both having the null hypersurface as history. The stress-energy in the shell is dominated (at large distance from the source) by the jump in the monopole moment (the mass) of the source with the jump in the quadrupole moment mainly responsible for the stress being anisotropic. The gravitational wave owes its existence principally to the jump in the quadrupole moment of the source confirming what would be expected.

Performance of missing transverse momentum reconstruction in proton-proton collisions at $\sqrt{s} =$ 13 TeV using the CMS detector

description: The performance of missing transverse momentum (${\vec p}_{\mathrm{T}}^\mathrm{miss}$) reconstruction algorithms for the CMS experiment is presented, using proton-proton collisions at a center-of-mass energy of 13 TeV, collected at the CERN LHC in 2016. The data sample corresponds to an integrated luminosity of 35.9 fb$^{-1}$. The results include measurements of the scale and resolution of ${\vec p}_{\mathrm{T}}^\mathrm{miss}$, and detailed studies of events identified with anomalous ${\vec p}_{\mathrm{T}}^\mathrm{miss}$. The performance is presented of a ${\vec p}_{\mathrm{T}}^\mathrm{miss}$ reconstruction algorithm that mitigates the effects of multiple proton-proton interactions, using the "pileup per particle identification" method. The performance is shown of an algorithm used to estimate the compatibility of the reconstructed ${\vec p}_{\mathrm{T}}^\mathrm{miss}$ with the hypothesis that it originates from resolution effects.

Picturesque Transformations: A. J. Davis in the Hudson Valley and Beyond

description: This thesis examines the role English landscape gardening played in shaping the career and working methods of the American architect Alexander Jackson Davis (1803â€ 1892) and its implications for preserving his surviving body of work in the Hudson Valley. The study is organized around a detailed study of four Davis country house projects (Blithewood, The Dr. Oliver Bronson House, Montgomery Place, and Locust Grove), each of which involve the redesign of an existing house and landscape into a radically different form; a specific mode of transformation that has a long history within English landscape gardening tradition. What emerges from this study is a very different view of A. J. Davis's professional identity than has been traditionally appreciated and a different way to "read" his watercolor drawings. In an era before the professionalization of the architectural discipline, English landscape gardening offered Davis an attractive working model to practice architecture as an artist, using his compositional skills to create artistically cohesive scenes in real landscapes blending the techniques of landscape painting and architectural design. All of this was shaped by English precedents Davis learned about through his participation in the early National Academy of Design under Samuel F. B. Morse (1791â€ 1872) and Davis's documented reading of English landscape gardening books. Following such influential English role models as Humphry Repton (1752â€ 1818), Davis designed onsite rather than drafting plans and elevations in the office, working to capture the actual conditions of light and shade, texture and color, in his designs and compositions. And like Repton, Davis was equally concerned with both "aspects" and "prospects," the way architecture formed a part of the landscape composition and framed the view outward. This thesis explores how Davis employed landscape gardening in four major country house commissions, documenting the existing conditions before he arrived on the scene and the process by which both the architectural elements in the landscape and the landscape itself was transformed over time into unified picturesque compositions. Understanding Davis in this way has major implications for preservation and interpretation of his surviving work. Landscape restoration assumes an equal position with architectural restoration. To assist current preservation work, this thesis offers a set of recommended strategies for each of the four case study sites that flow directly from the analysis and Davis's conception of landscape and architecture as inseparable parts of a single artistic whole.

description: Mining companies have become increasingly focused on developing environmentally responsible decommissioning and closure techniques of tailings facilities to work towards more sustainable mining practices. With the help of the Mining Association of Canada (MAC) guidelines, the development and implementation of functional and manageable Operation, Maintenance and Surveillance (OMS) manuals for operating tailings facilities have become commonplace. As more tailings facilities are decommissioned and closed, and the expectations of regulators and society continue to grow, the need for further guidance through the application of similar documentation for the management of the post-closure facility also increases. This paper highlights the importance of developing a post-closure OMS manual for the management of closed tailings facilities (and other mining landforms), by way of a post-closure OMS guidebook. It describes initial ideas in the development of post-closure OMS manuals and provides some reasoning, structure and contents for a post-closure OMS manual. It would be encouraged that tailings facility reclamation personnel utilise a universal post-closure OMS guidebook to prepare a site-specific post-closure OMS manual. This paper references a range of sources and first hand experiences by the authors.
