description: Quasi-periodic oscillations (QPOs) are coherent peaks of variability power observed in the X-ray power spectra (PSDs) of stellar mass X-ray binaries (XRBs). A scale invariance of the accretion process implies they should be present in the active galactic nuclei. The first robust detection was a $\sim 1$ hr periodicity in the Seyfert galaxy RE J1034+396 from a $\sim 90$ ks XMM-Newton observation, however, subsequent observations failed to detect the QPO in the $0.3-10.0$ keV band. In this talk we present the recent detection of the $\sim 1$ hr periodicity in the $1.0-4.0$ keV band of 4 further low-flux/spectrally-harder observations of RE J1034+396 (see Alston et al 2014). We also present recent work on the discovery of a QPO in the Seyfert galaxy, MS 22549-3712, which again is only detected in energy bands associated with the primary power-law continuum emission (Alston et al 2015). We conclude these features are most likely analogous to the high-frequency QPOs observed in XRBs. In both sources, we also see evidence for X-ray reverberation at the QPO frequency, where soft X-ray bands and Iron K$α$ emission lag the primary X-ray continuum. These time delays may provide another diagnostic for understanding the underlying QPO mechanism observed in accreting black holes.

Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2007

description: The p21-activated kinases (PAKs) are downstream effectors of signal transducers including Rac and Cdc42. PAKs are involved in cytoskeletal rearrangements during cell migration, mitosis, dendritic spine formation, and neurite outgrowth. While the general expression pattern of PAKs in the brain was known, possible effects of PAK kinase activity on early brain development had not been described. I studied the expression pattern of activated PAKs 1-3 by immunoblotting and immunofluorescence in embryonic mouse brains and the effect of disruption of PAK activity during development on radial migration and early neuronal remodeling at the cortical plate. Active PAKs were observed in progenitor cells, in which they were coexpressed with PAK1 phosphorylated at T212, and in the developing cortical plate. Disruption of PAK activity did not affect radial cell distribution in the neocortex or neurite number in early neurons in the cortical plate.
The rational soul as the cause of unification in the tripartite soul
Creators: name: Kocieda, Sylvia
Publisher: name: University of North Carolina at Chapel Hill
Year: 2014

description: Discussions regarding unity in the Platonic tripartite soul generally surround the issue of achieving virtue. However, there must exist some type of fundamental, unearned unity between the parts of the soul prior to achieving virtue which affords the agent meaningful interactions between the three soul-parts and the unity of consciousness. In this paper, I argue that the possession of the rational soul warrants unification of the pre-virtuous soul since the function of reason is precisely to be responsible for the organization and intelligibility of parts. In view of this, I suggest that the rational soul itself is the basis for the unearned unity of the soul. My view is developed against the standing view by Eric Brown in which unearned unification is achieved by the causal relationship between the three soul-parts, which makes the soul-parts tend toward agreement.
Numerical modelling of amorphous solids: A classical density functional theory based approach

Publisher: name: Loughborough University

Subjects: Other mathematical sciences not elsewhere classified

description: In this thesis, the Phase-Field Crystal (PFC) model is used to describe amorphous solid materials. These stationary states are metastable minima of the free energy, that are characterised by a non-uniform density distribution displaying no long-range order. In the introductory part of the thesis, first we give a summary of the thermodynamics and kinetics of phase transitions, which is followed by an introduction to the Classical Density Functional Theory (DFT) and its dynamical extension (DDFT), in which the physical state of the matter is characterised by a spatiotemporal scalar field, the density distribution. This part of the thesis ends with the derivation of the PFC model from the DDFT, which is then used to investigate the bulk thermodynamic and microscopic structural properties of amorphous solids. In the next part of the thesis, we present and analyse the results of extensive numerical simulations. First, we determine the distribution of the free energy density in the amorphous state for various system sizes, and show that the amorphous state can be modelled as a collection of uncorrelated finite-sized domains. We calculate the typical size (correlation length) of these correlated regions.

description: With the design and development of next-generation high-energy neutrino detectors, it is important to compare different detector designs to optimize detection probability and science reach. These comparisons are nevertheless difficult due to large uncertainties in current neutrino source model parameters. We examine the role of the most important characteristics of high-energy neutrino searches in the probability of discovering different sources types. We derive scaling relations for each considered source and search scenario, which can be used to compare different detector designs with respect to their utility in discovering different source populations. The recovered scaling relations are independent of source strengths, providing a model-independent comparison.
Pre and post zygotic fitness components of hybridization in spadefoot toads
Creators: name: Wojtowicz, Elizabeth
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2009

description: When hybrids are unfit, selection favors the evolution of pre-mating barriers that impede gene flow and promote population differentiation. Hybrid fitness, however, is complex and may vary across life-stages. Additionally, the costs may differ between species. Using spadefoot toads I examined pre- and post- zygotic fitness components of hybridization. First, I focused on two post-mating pre-zygotic barriers: fertilization success and clutch size. Fertilization success did not differ between conspecific and heterospecific males. Average clutch size did not differ as a result of heterospecific pairing. Therefore, species-specific gamete recognition is absent between these species. Second, I investigated post-zygotic fitness components of hybrid growth and survival in the period immediately following metamorphosis. Data suggests that while hybridization may be beneficial in early development, condition immediately following metamorphosis may lead to decreased survival over time. Hybrids were intermediate in size, suggesting one species may benefit more than the other.

description: Graphynes are 2D porous structures deriving from graphene featuring triangular and regularly distributed subnanometer pores, which may be exploited to host small gaseous species. First principles adsorption energies of molecular hydrogen (H2) on graphene, graphdiyne and graphtriyne molecular prototypes are obtained at the MP2C level of theory. First, a single layer is investigated and it is found that graphynes are more suited than graphene for H2 physical adsorption since they provide larger binding energies at equilibrium distances much closer to the 2D plane. In particular, for graphtriyne a flat minimum located right in the geometric center of the pore is identified. A novel graphite composed of graphtriyne stacked sheets is then proposed and an estimation of its 3D arrangement is obtained at the DFT level of theory. In contrast to pristine graphite this new carbon material allow both H2 intercalation and out-of-plane diffusion by exploiting the larger volume provided by its nanopores. Related H2 binding energies for intercalation and in-pore adsorption are around 0.1 eV and they could lead to high storage capacities. The proposed carbon-based layered material could represent a safer and potentially cheaper alternative for hydrogen on-board storage than conventional solutions based on cryogenic liquefaction and/or high compression.

description: We show how the large-scale cosmological dynamics can be obtained from the hydrodynamics of isotropic group field theory condensate states in the Gross-Pitaevskii approximation. The correct Friedmann equations are recovered in the semi-classical limit for some choices of the parameters in the action for the group field theory, and quantum gravity corrections arise in the high-curvature regime causing a bounce which generically resolves the big-bang and big-crunch singularities.

description: We investigate the observational signatures and physical origin of ram-pressure stripping (RPS) in 63 massive galaxy clusters at $z=0.3-0.7$, based on images obtained with the Hubble Space Telescope. Using a training set of a dozen "jellyfish" galaxies identified earlier in the same imaging data, we define morphological criteria to select 211 additional, less obvious cases of RPS. Spectroscopic follow-up observations of 124 candidates so far confirmed 53 as cluster members. For the brightest and most favourably aligned systems we visually derive estimates of the projected direction of motion based on the orientation of apparent compression shocks and debris trails. Our findings suggest that the onset of these events occurs primarily at large distances from the cluster core ($>400$ kpc), and that the trajectories of the affected galaxies feature high impact parameters. Simple models show that such trajectories are highly improbable for galaxy infall along filaments but common for infall at high velocities, even after observational biases are accounted for, provided the duration of the resulting RPS events is $\lesssim$500 Myr. We thus tentatively conclude that extreme RPS events are preferentially triggered by cluster mergers, an interpretation that is supported by the disturbed dynamical state of many of the host clusters. This hypothesis implies that extreme RPS might occur also near the cores of merging poor clusters or even merging groups of galaxies. Finally, we present nine additional "jellyfish" galaxies at z$>$0.3 discovered by us, thereby doubling the number of such systems known at intermediate redshift.

Using this, we present a simple proof of the classification of closed surfaces.

title: The development of trade unionism among British automobile and aircraft workers 1914-1946
Creators: name: Claydon, T. J.
Publisher: name: University of Kent
Year: 2023

description: This study is concerned with the early development of trade unionism in the British motor and aircraft industries. Its aim is to estimate the course of union membership and organisational density, to identify their main determinants and to analyse the evolving pattern of organisation. The chief emphasis throughout is on the motor industry but considerable attention has been paid to aircraft manufacture because of the existence of close links between the two industries and the possibility of useful comparison between them. Chapter One defines the scope of the study, reviews the theoretical literature on union growth and development in structure and gives a preliminary discussion of its application to this particular area. Chapters Two and Three describe the main phases in the growth of trade unionism and provide rough quantitative estimates of changes in union strength. Chapter Four applies the analytical framework developed in Chapter One to build up an intuitive model of union growth in the motor and aircraft industries. Chapter Five analyses the developing pattern of organisation in the context of the appropriate literature summarised in Chapter One. It is concluded that the path of union growth in the motor industry was determined by the interplay of general movements in the economy which operated on employment, prices and money wages with certain features of the motor industry's development, chiefly its technical and market structure, that of its labour force and the working conditions prevailing within it. The pattern of union organisation in 1946 is seen as the result of trade unions having different initial jurisdictional bases responding to pressures arising out of general economic movements e.g. depression and changes in production techniques in the automobile, aircraft and engineering industries.

description: In spite of the technological advancement on building design and construction, actual energy use levels of dwellings are different than expected in several cases. Little is known about how occupants interact with their dwellings, what the background to this interaction is, as well as the resulting energy use. This research aimed at revealing the relationship between occupant behavior and energy consumption, both in terms of heating energy and electricity. The determinants of occupant behavior, the sensitivity of dwelling energy consumption to occupant behavior, and defining behavioral patterns/profiles are the main elements of this work. This thesis will help to understand the occupant related factors of energy consumption in dwellings, by this way designing better products, energy management systems, software, and achieving better regulations. Research on energy consumption of dwellings covers thorough investigation of the behavioral performance during the occupancy process, as well as the aspects that are involved in the design and building processes. There has been extensive progress on the building physics aspects of energy consumption; concerning methods and practices for specification of building geometry, material properties, and external conditions. However, the resolution of input information regarding occupant behavior is still rather low. In order to respond to this, one of the research questions of this thesis has been: what is the sensitivity of dwelling energy consumption to occupant behavior? Secondly, the influence of lighting and appliance use on electricity consumption, as well as the determinants of electricity consumption in dwellings, and lastly, the behavioral patterns of energy consumption are investigated. This study’s methodological approach combined the deductive and the inductive methods, by considering both the determinants of behavior and the actual behavior itself. Deductive methods dissect energy consumption into its factors, such as household characteristics, dwelling characteristics, behavioral aspects, etc. On the other hand, inductive methods model actual behavior from bottom up experimenting and validating energy consumption levels. In this thesis, occupant behavior was considered as presence patterns in a space, together with the actual heating (thermostat setting and radiator control) and ventilation patterns (operation of windows, grids, and mechanical systems), and the use of lighting and appliances. This research looked at the building and household characteristics that determine occupant behavior, as well as habitual (surveyed) and actual (monitored) occupant behavior.

description: We study the links between star formation history and structure for a large mass-selected galaxy sample at 0.05 < z_phot < 0.30. The galaxies inhabit a very broad range of environments, from cluster cores to the field. Using HST images, we quantify their structure following Hoyos et al. (2012), and divide them into disturbed and undisturbed. We also visually identify mergers. Additionally, we provide a quantitative measure of the degree of disturbance for each galaxy ("roughness"). The majority of elliptical and lenticular galaxies have relaxed structure, showing no signs of ongoing star formation. Structurally-disturbed galaxies, which tend to avoid the lowest-density regions, have higher star-formation activity and younger stellar populations than undisturbed systems. Cluster spirals with reduced/quenched star formation have somewhat less disturbed morphologies than spirals with "normal" star-formation activity, suggesting that these "passive" spirals have started their morphological transformation into S0s. Visually identified mergers and galaxies not identified as mergers but with similar roughness have similar specific star formation rates and stellar ages. The degree of enhanced star formation is thus linked to the degree of structural disturbance, regardless of whether it is caused by major mergers or not. This suggests that merging galaxies are not special in terms of their higher-than-normal star-formation activity. Any physical process that produces "roughness", or regions of enhanced luminosity density, will increase the star-formation activity in a galaxy with similar efficiency. An alternative explanation is that star formation episodes increase the galaxies' roughness similarly, regardless of whether they are merger-induced or not.

description: We prove two results about the derived functor of $a$-adic completion: (1) Let $K$ be a commutative noetherian ring, let $A$ be a flat noetherian $K$-algebra which is $a$-adically complete with respect to some ideal $a\subseteq A$, such that $A/a$ is essentially of finite type over $K$, and let $M,N$ be finitely generated $A$-modules. Then adic reduction to the diagonal holds: $A\otimes^{L}_{ A\hat{\otimes}_{K} A } ( M\hat{\otimes}^{L}_{K} N ) \cong M \otimes^{L}_A N$. A similar result is given in the case where $M,N$ are not necessarily finitely generated. (2) Let $A$ be a commutative ring, let $a\subseteq A$ be a weakly proregular ideal, let $M$ be an $A$-module, and assume that the $a$-adic completion of $A$ is noetherian (if $A$ is noetherian, all these conditions are always satisfied). Then $\mbox{Ext}^i_A(A/a,M)$ is finitely generated for all $i\ge 0$ if and only if the derived $a$-adic completion $Ł\hatΛ_{a}(M)$ has finitely generated cohomologies over $\hat{A}$. The first result is a far reaching generalization of a result of Serre, who proved this in case $K$ is a field or a discrete valuation ring and $A = K[[x_1,\dots,x_n]]$.

description: Multi-modal image registration is a challenging task that is vital to fuse complementary signals for subsequent analyses. Despite much research into cost functions addressing this challenge, there exist cases in which these are ineffective. In this work, we show that (1) this is true for the registration of in-vivo Drosophila brain volumes visualizing genetically encoded calcium indicators to an nc82 atlas and (2) that machine learning based contrast synthesis can yield improvements. More specifically, the number of subjects for which the registration outright failed was greatly reduced (from 40% to 15%) by using a synthesized image.

description: In the previous Chapter we made a sensitivity analysis based on actual energy consumption and heating behavior, on the whole OTB sample using methods like Markov chain and Monte Carlo analysis. In this Chapter (Chapter 5) a deeper analysis of heating behavioral patterns is reported. The study included 61 houses randomly chosen from the Netherlands, monitored for 2 months during March and April 2011. The thermostat use patterns of households were studied as well as chosen maximum and minimum set points each day for the whole sample. Then these patterns were correlated with the household and dwelling characteristics of the sample. Unfortunately, the collected energy consumption data for this sample was not reliable to be included in the analysis. This Chapter deals with the Research Question III-1 of this thesis: (Chapter 1, Section 3, pg. 16-17) “ III. What are the behavioral patterns and profiles of energy consumption? The sub-question is: What are the behavioral patterns of thermostat control? How do they relate to the household characteristics, revealing behavioral profiles?” The research reported in this Chapter was conducted by Bedir, borrowing the dataset of Sonja van Dam. The data was collected through monitoring, by and for Sonja van Dam for her PhD research, using ENECO’s means of data collection.

description: Models and methods that are able to accurately and efficiently predict the flows of low-speed rarefied gases are in high demand, due to the increasing ability to manufacture devices at micro and nano scales. One such model and method is a Fokker-Planck approximation to the Boltzmann equation, which can be solved numerically by a stochastic particle method. The stochastic nature of this method leads to noisy estimates of the thermodynamic quantities one wishes to sample when the signal is small in comparison to the thermal velocity of the gas. Recently, Gorji et al have proposed a method which is able to greatly reduce the variance of the estimators, by creating a correlated stochastic process which acts as a control variate for the noisy estimates. However, there are potential difficulties involved when the geometry of the problem is complex, as the method requires the density to be solved for independently. Importance sampling is a variance reduction technique that has already been shown to successfully reduce the noise in direct simulation Monte Carlo calculations. In this paper we propose an importance sampling method for the Fokker-Planck stochastic particle scheme. The method requires minimal change to the original algorithm, and dramatically reduces the variance of the estimates. We test the importance sampling scheme on a homogeneous relaxation, planar Couette flow and a lid-driven-cavity flow, and find that our method is able to greatly reduce the noise of estimated quantities. Significantly, we find that as the characteristic speed of the flow decreases, the variance of the noisy estimators becomes independent of the characteristic speed.

Other salient aspects of this "cultural offensive," as contemporary American observers characterized it, included Latin American tours by Soviet musicians and theatre troupes as well as exchanges of parliamentary delegations. Such high-brow efforts catered to Latin American elites and politicians, while the organizers of these exhibitions primarily hoped to attract the attention of "ordinary people." With their low ticket prices and timely displays-which included the Lunik and Sputnik spacecraft-these exhibitions drew in millions of visitors.

description: The OI 777 nm lines are among the most commonly used diagnostics for the oxygen abundances in the atmospheres of FGK-type stars. However, they form in conditions that are far from local thermodynamic equilibrium (LTE). We explore the departures from LTE of atomic oxygen, and their impact on OI lines, across the Stagger-grid of three-dimensional hydrodynamic model atmospheres. For the OI 777 nm triplet we find significant departures from LTE. These departures are larger in stars with larger effective temperatures, smaller surface gravities, and larger oxygen abundances. We present grids of predicted 3D non-LTE based equivalent widths for the OI616nm, [OI] 630 nm, [OI] 636 nm, and OI 777 nm lines, as well as abundance corrections to 1D LTE based results.

description: Chapter 3 is a sensitivity analysis conducted using the actual heating behavior data of occupants in the OTB sample. The aim was to model heating behavior and heating energy consumption using Markov chains and Monte Carlo methods. Secondly we wanted to evaluate the robustness of energy consumption of a dwelling to heating behaviors such as thermostat, radiator and ventilation control, as well as presence. The results of this Chapter were compared to Guerra Santin’s work (2010), which analyzes the same data using correlation and regression analyses. This Chapter deals with the Research Question I of this thesis: “Q I. What is the sensitivity of a dwelling’s heating energy consumption to occupant behavior?" The sub-questions are: 1. What are the existing models developed for the occupant behavior and energy performance relationship? and how different are the results of these models in terms of calculating the influence of occupant behavior on energy performance? 2. How can behavior be modelled in order to assess the robustness of the energy performance in dwellings to occupant behavior? 3. What is the weight of each behavioral aspect in terms of its influence on energy consumption?” The research reported in this Chapter was a collaborative work between Harputlugil and Bedir. The data was collected by a questionnaire prepared by Guerra Santin and Bedir, using OTB’s means of data collection. Data organization and initial statistical analysis was done by Bedir, simulations were conducted by Harputlugil and Bedir together, and finally the evalutation of outputs were done by the same authors.

description: This study sets out to assess working memory capacity in people with high-level aphasia, who score above the threshold for disordered on standardized assessments but continue to report everyday communication challenges. Additionally, we collected subjective reports of everyday communication difficulties experienced by people with high-level aphasia. These reports were analyzed qualitatively to determine patterns across participants and identify potential sources of assessment and intervention. Five people with high-level aphasia and five neurologically healthy controls completed short-term and working memory tasks and participated in a semi-structured interview. Results indicate that short-term and working memory are impaired for at least some people with high-level aphasia and that digit span tasks have potential as sensitive measures for working memory impairment in high-level aphasia. Furthermore, people with high-level aphasia report salient communication difficulties, reduced social participation, difficulties returning to work, and a keen awareness of their persisting impairments. Implications for assessment and intervention are discussed with relation to both reduced working memory capacity and subjective communication difficulties reported by people with high-level aphasia.

description: Chapter 2 provides an overview of a literature study of the existing knowledge on energy consumption from the urban to the user scale, energy performance modelling methods, the energy performance gap, and insights to determinants of heating energy and electricity consumption. This review first helped to set up a reference point for the reasons to actual occupant behavior, how perception, lifestyle, norms, rules lead to various actions at home (Figure 1). Secondly, through this study, a framework for the relationship between occupant behavior and energy consumption was created (Figure 2), based on the determinants of behavior, i.e. occupant characteristics (educational, economic, social), dwelling characteristics (envelope, systems, lighting and appliances…). This literature study set the context and also the first steps of this research. The determinants found through this review (Table 2) gave input to the content and structure of the questions of the survey designed for the OTB dataset.

description: To investigate the barrier effect of grain boundaries on the propagation of avalanche-like plasticity at the atomic-scale, we perform three-dimensional molecular dynamics simulations by using simplified polycrystal models including symmetric-tilt grain boundaries. The cut-offs of stress-drop distributions following power-law distributions decrease as the size of the crystal grains decreases. We show that some deformation avalanches are confined by grain boundaries; on the other hand, unignorable avalanches penetrate all the grain boundaries included in the models. The blocking probability that one grain boundary hinders this system-spanning avalanche is evaluated by using an elemental probabilistic model.

description: In this paper, we present the synchrotron light curve at 610 MHz from the recurrent nova V745 Sco following its outburst on 6 February 2014. The system has been detected and periodically monitored with the Giant Metrewave Radio Telescope (GMRT) since 9 February 2014 as part of the Galactic Nova with GMRT (GNovaG) project. The light curves are well fit by a model of synchrotron emitting region obscured by foreground thermal gas which eventually becomes optically thin to the low GMRT frequencies. We present the model fit to the 2014 data on V745 Sco and discuss it alongwith the model fit to the 1.4 GHz data of the recurrent nova RS Ophiuchi following its outburst in 1985.

description: This thesis has researched further design and development of a system for vario-scale maps. Section 7.1 presents our ultimate vario-scale goal, which will give us perspective to understand issues addressed in the previous chapters such as further development of current generalization tools considering better vario-scale content (Chapter 4), pro- cessing of a large dataset not ﬁtting in main memory (Chapter 5) and smooth user in- teraction (Chapter 6). All these aspects are now brought together in this chapter where they will be summarized and critically evaluated. The main contributions will be put in the context of the thesis by answering the research questions in Section 7.2, mean- while new op r future research will be covered in Section 7.3.

Developing secondary school students’ procedural fluency with cover, copy and compare
Creators: name: Strauss, Jacob
Publisher: name: Loughborough University
Year: 2023

description: The aim of this thesis is to establish the efficacy of Cover, Copy and Compare (CCC) for improving secondary-level mathematical procedures. CCC is a well-established method for enhancing the computational fluency of primary school students (ages 6-11) and students with special educational needs. Despite extensive research on the utility of CCC for primary-level mathematics, there exists no published empirical work that considers CCC as a method for developing mainstream secondary school students’ (ages 11-16) procedural fluency. To address this limitation, I created a CCC mobile application (app) that has secondary school students practise finding the equation of a straight line given the Cartesian coordinates of two points. In this thesis, I describe the complete processes of designing, developing, testing, refining and ultimately evaluating this app. In a randomised controlled trial, I showed that secondary school students using the CCC app make significantly greater improvements in their procedural fluency with finding the equation of a straight line given two points than students using an app comprising typical classroom exercises. Furthermore, by quantitatively exploring the app’s event logs, I identified an association between class membership and fluency gains made using the app, suggesting that classroom-level factors influence procedural fluency outcomes when implementing CCC in secondary mathematics classrooms. The overall findings of this thesis imply that CCC may be beneficial for developing secondary mathematics students’ procedural fluency and informs our understanding of what effective procedural fluency practise entails.
H9N2 Avian Influenza A Virus: Impact of Serial Passaging by Aerosol Exposure on Pathogenicity in Chickens

description: The H9N2 low pathogenic avian influenza virus (LPAIV) is considered a prime candidate for evolving into a highly pathogenic AIV (HPAIV) following circulation in domestic poultry, due to its widespread endemism in Eurasia and the donation of internal genes to H5 and H7 HPAIV. In this study, we investigated if a LP H9N2 virus could acquire increased pathogenicity following nineteen serial passages in week-old chickens. We show that the H9N2 virus remained low pathogenic in chickens after nineteen serial passages, evidenced by a lack of mortality in chickens despite efficient viral replication in chicken organs. An overregulation of cytokine response to infection, typical of highly pathogenic viruses, was not observed in tissue organs analyzed by quantitative PCR. The serial passaging of the H9N2 virus led to reduced virulence in chicken embryos and reduction in Hemagglutinin heat stability after passaging. The positive selection of Leucine at amino acid position 226 (L226) after 19 passages suggests the H9N2 can gain mammalian adaptation markers following circulation in domestic poultry. In addition, we carried out four experiments to determine the effectiveness of aerosol exposure of H6N1, H10N7, H10N8 and H13N6 LPAIV’s in causing infection, immune dysregulation and mortality in chickens compared to intranasal and oral inoculation routes. From our study, we observed mortality of chickens exposed to H6N1 and H10N8 viruses via aerosols. Aerosol exposure also resulted in more efficient replication in the respiratory tracts of chickens than intranasal or oral inoculated chickens. In addition, overexpression of pro-inflammatory (IL-6, IL-1ß) and antiviral (INF- γ) cytokines was observed in chickens exposed to aerosols compared to intranasal and oral inoculation. Our results show that the aerosol route of exposure is efficient at causing infection in chickens and should be factored into control and prevention strategies against AIV.
A Hamiltonian treatment of stimulated Brillouin scattering in nanoscale integrated waveguides

description: We present a multimode Hamiltonian formulation for the problem of opto-acoustic interactions in optical waveguides. We establish a Hamiltonian representation of the acoustic field and then introduce a full system with a simple opto-acoustic coupling that includes both photoelastic/electrostrictive and radiation pressure/moving boundary effects. The Heisenberg equations of motion are used to obtain coupled mode equations for quantized envelope operators for the optical and acoustic fields. We show that the coupling coefficients obtained coincide with those established earlier, but our formalism provides a much simpler demonstration of the connection between radiation pressure and moving boundary effects than in previous work [C. Wolff et al, Physical Review A 92, 013836 (2015)].
