description: We report on the Swift detection of a thermonuclear X-ray burst from the very-faint quasi-persistent neutron star X-ray binary XMMU J174716.1-281048, which triggered the satellite's Burst Alert Telescope (BAT) on 2010 August 13. Analysis of the BAT spectrum yields an observed bolometric peak flux of ~4.5E-8 erg/cm2/s, from which we infer a source distance of <8.4 kpc. Follow-up observations with Swift's X-ray Telescope (XRT) suggest that the event had a duration of ~3 h and a total radiated energy of ~9E40 erg, which classify it as an intermediately long X-ray burst. This is only the second X-ray burst ever reported from this source. Inspection of Swift/XRT observations performed between 2007-2010 suggests that the 2-10 keV accretion luminosity of the system is only ~5E34 erg/s for an assumed distance of 8.4 kpc. Despite being transient, XMMU J174716.1-281048 appears to have been continuously active since its discovery in 2003.

The effects of anisotropic turbulence on fibre motion
Creators: name: Holt, Kyle
Publisher: name: University of British Columbia
Year: 2017

description: Fibre orientation and concentration distributions in a turbulent suspension are typically modeled by the Fokker-Planck equation and dispersion coefficients that relate the fluid turbulence properties to the fibre length, assuming an infinitely thin, and inertialess fibre. These predictions are used in a wide variety of engineering problems, notably the forming of paper. There is substantial literature examining the application of the Fokker-Planck equation for isotropic turbulence, however, there are few studies that examine the effect of turbulence anisotropy on fibre translational and rotational dispersion. In order to provide better estimates of fibre orientation and concentration distributions in an anisotropic turbulent suspension, the relationship between turbulence and fibres needs to be better understood. This thesis develops a stochastic model which can be used to determine the orientational and translational dispersion coefficients. The fluid model is based on the Kraichnan turbulence fluid model [1] and the fibres are represented by rigid, inertialess infinitely thin particles assumed to be in a dilute suspension. The turbulence is made axisymmetric by utilizing the time dependent wavevector relation from Rapid Distortion Theory [2]. This enables the model to simulate the physical effects of eddy distortion by a contraction. A range of fibre lengths and contraction ratios were modeled, and it was found that the translational dispersion coefficient increases in magnitude with contraction ratio and decreases with fibre length while the rotational dispersion coefficient decreases with both contraction ratio and fibre length. A constant was found relating the isotropic and anisotropic translational dispersion coefficients, based on contraction ratio. The simulation showed that the integral time scale for translation increased for short fibres and decreased for long fibres as contraction ratio increased for both directions. The integral time scale for rotation decreased for small fibres and increased to a maximum before decreasing for long fibres as contraction ratio increased for both directions. It was shown that fibre orientation tended to the radial orientation preferentially as contraction ratio increased but spent more time in the streamwise orientation as fibre length increased. These findings will allow for improved estimates to be made for anisotropic dispersion coefficients.
Bs Mixing and Electric Dipole Moments in MFV

description: We analyze the general structure of four-fermion operators capable of introducing CP-violation preferentially in Bs mixing within the framework of Minimal Flavor Violation. The effect requires a minimum of O(Yu^4 Yd^4) Yukawa insertions, and at this order we find a total of six operators with different Lorentz, color, and flavor contractions that lead to enhanced Bs mixing. We then estimate the impact of these operators and of their close relatives on the possible sizes of electric dipole moments (EDMs) of neutrons and heavy atoms. We identify two broad classes of such operators: those that give EDMs in the limit of vanishing CKM angles, and those that require quark mixing for the existence of non-zero EDMs. The natural value for EDMs from the operators in the first category is up to an order of magnitude above the experimental upper bounds, while the second group predicts EDMs well below the current sensitivity level. Finally, we discuss plausible UV-completions for each type of operator.

Thereby detailed insights in the process were gained, which are not achievable or only under great efforts with conventional methods.
Biological response of Spisula solidissima (Atlantic surfclams) to varying carbonate chemistry in the Mid-Atlantic Bight
Creators: name: DiRenzi, Breana
Publisher: name: No Publisher Supplied
Year: 2023

description: Spisula solidissima (Atlantic surfclams) are bottom dwelling bivalves native to the Mid-Atlantic Bight (MAB). They are sensitive to ongoing climate change-induced ocean warming and ocean acidification. Ocean warming has increased bottom temperatures and ocean and coastal acidification has depressed the aragonite saturation state (ΩArag), an essential mineral for shell-forming organisms. Ongoing changes in carbonate chemistry may negatively impact the physiology of surfclams which could in turn impact New Jersey surfclam fisheries. A gap in ocean acidification research is access to co-located biological response monitoring. Most literature on organism response is from single-species laboratory studies and may not capture realistic, natural conditions, or variability. Simultaneous measurements of surfclam biological response indicators need to be co-located with carbonate chemistry observations in the field to observe and predict biological impact in situ. The objective of this project was to conduct co-located sampling to determine the correlation between observed carbonate chemistry an biological data from Atlantic surfclams in their natural habitat. A vessel-based survey was performed to collect oceanographic measurements, including carbonate chemistry, and surfclam samples off New Jersey on the Mid-Atlantic shelf. Mean bottom or subsurface oceanographic measurements were used as inputs to ΩArag. A subsample of surfclams at each station were measured for shell length, thickness, and weight. Shell strength was also determined using a tensile strength machine and was defined as the force(kiloNewtons) applied in the middle of the shell at which the shell begins to break. Shell strength was standardized to shell weight for each shell (kN/g). Results showed no significant correlations between shell strength and carbonate chemistry. This could be due to potential acclimation capacity, potential buffering capacity of seawater, and/or potential energy reallocation. The results indicate that shell strength may not be the best metric to determine the impacts on Atlantic surfclams in a highly variable environment. The exposure to low pH/ΩArag may need to be much longer to see responses in shell strength. The lack of correlation between shell strength and carbonate chemistry does not mean that Atlantic surfclams were not impacted by pH and ΩArag, but other unmeasured physiological metrics may have instead been affected.

description: We study theoretically the role of quenched magnetic disorder at the surface of a topological insulator by numerical simulation and scaling analysis. It is found that all the surface states are localized while the transverse conductivity is quantized to be $\pm {{e^2} \over {2 h}}$ as long as the Fermi energy is within the bulk gap. This greatly facilitates the realization of the topological magnetoelectric effect proposed by Qi {\it et al.} (Phys. Rev. B\textbf{78}, 195424 (2008)) with the surface magnetization direction being controlled by the simultaneous application of magnetic and electric fields .

description: Atomic wave packets in optical lattices which are both spatially finite and time-dependent exhibit many striking similarities with light pulses in photonic crystals. We analytically characterize the transmission properties of such a potential geometry for an ideal gas in terms of a position-dependent band structure. In particular, we find that at specific energies, wave packets at the center of the finite lattice may be enclosed by pairs of band gaps. These act as mirrors between which the atomic wave packet is reflected, thereby effectively yielding a matter wave cavity. We show that long trapping times may be obtained in such a resonator and investigate the collapse and revival dynamics of the atomic wave packet by numerical evaluation of the Schrödinger equation.
High Energy Neutrino Emission from the Earliest Gamma-Ray Bursts

description: We discuss the high energy neutrino emission from gamma-ray bursts resulting from the earliest generation (`population III') stars forming in the Universe, whose core collapses into a black hole. These gamma-ray bursts are expected to produce a highly relativistic, magnetically dominated jet, where protons can be accelerated to ultra-high energies. These interact with the photons produced by the jet, leading to ultra-high energy photo-meson neutrinos as well as secondary leptons and photons. The photon luminosity and the shock properties, and thus the neutrino spectrum, depend on the mass of the black holes as well as on the density of the surrounding external gas. We calculate the individual source neutrino spectral fluxes and the expected diffuse neutrino flux for various source parameters and evolution scenarios. Both the individual and diffuse signals appear detectable in the 1-300 PeV range with current and planned neutrino detectors such as IceCube and ARIANNA, provided the black hole mass is in excess of 30-100 solar masses. This provides a possible test for the debated mass of the progenitor stellar objects, as well as a probe for the early cosmological environment and the formation rate of the earliest structures.

Wideband timing of the double pulsar (PSR J0737-3039A)
Creators: name: Grandy, Victoria Rebecca
Publisher: name: University of British Columbia
Year: 2017

description: Pulsars are neutron stars (NS) that produce beamed radio-frequency emission. Due to their rapid, steady rotation rate, this signal is detected as a series of pulses whose integrated profile is unusually stable over time. Pulsars in double neutron star (DNS) binary systems are a rare, but extremely useful, astronomical tool and have been used in tests of gravity theories in the strong-gravitational field limit. Rarer still are DNS systems in which both objects have been detected as pulsars; only one such system has been found thus far -- PSR J0737-3039A/B. Discovered over a decade ago, this system consists of one recycled pulsar, PSR J0737-3039A, and its companion, PSR J0737-3039B, which has since become undetectable. In any pulsar-related research, precise timing is necessary to produce meaningful results. The pulse time of arrivals (TOAs) are greatly affected by the medium through which the electromagnetic (EM) signal travels in both frequency-dependent and -independent ways. Even after accounting for such effects, many pulse profiles still exhibit frequency-dependent shape changes, which can greatly affect the precision of the timing results. Traditionally, corrections are applied to the TOAs after calculation in an ad hoc manner. In contrast to this, we explored the wideband timing algorithm developed by Timothy T. Pennucci and collaborators which accounts for frequency-dependent profile changes through a two-dimensional Gaussian pulse portrait model implemented in the TOA calculations. It was found that the portrait model is well-representative of the pulse profile shape over a wide frequency range. This method is also able to produce a robust set of wideband TOAs. The subsequent timing model, determined with TEMPO timing software, was found to be comparable to those produced from subbanded TOAs derived though more traditional methods. Some inconsistencies between the timing model astrometric and spin parameters of the wideband and subbanded data of this well-studied pulsar imply potential difficulties in achieving precise timing results not only for this pulsar, but for others, such as those used in pulsar timing arrays aiming to detect gravitational waves.

description: The properties of surfaces with charge-regulated patches are studied using non-linear Poisson-Boltzmann theory. Using a mode expansion to solve the non-linear problem efficiently, we reveal the charging behaviour of Debye-length sized patches. We find that patches charge up to higher charge densities if their size is relatively small and if the patches are well separated. The numerical results are used to construct a basic analytical model which predicts the average surface charge density on surfaces with patchy chargeable groups.

description: We study black hole solutions of Einstein gravity coupled to a specific global symmetry breaking Goldstone model described by an O(3) isovector scalar field in four spacetime dimensions. Our configurations are static and spherically symmetric, approaching at infinity a Minkowski spacetime background. A set of globally regular, particle-like solutions are found in the limit of vanishing event horizon radius. These configurations can be viewed as 'regularised' global monopoles, since their mass is finite and the spacetime geometry has no deficit angle. As an unusual feature, we notice the existence of extremal black holes in this model defined in terms of gravity and scalar fields only.

description: The discovery of cosmic rays, a milestone in science, comprised scientists in Europe and the US and took place during a period characterised by nationalism and lack of communication. Many scientists that took part in this research a century ago were intrigued by the penetrating radiation and tried to understand the origin of it. Several important contributions to the discovery of the origin of cosmic rays have been forgotten and in particular that of Domenico Pacini, who in June 1911 demonstrated by studying the decrease of radioactivity with an electroscope immersed in water that cosmic rays could not come from the crust of the Earth. Several historical, political and personal facts might have contributed to the substantial disappearance of Pacini from the history of science.

description: We study a one-dimensional hamiltonian chain of masses perturbed by an energy conserving noise. The dynamics is such that, according to its hamiltonian part, particles move freely in cells and interact with their neighbors through collisions, made possible by a small overlap of size $ε> 0$ between near cells. The noise only randomly flips the velocity of the particles. If $ε\rightarrow 0$, and if time is rescaled by a factor $1/ε$, we show that energy evolves autonomously according to a stochastic equation, which hydrodynamic limit is known in some cases. In particular, if only two different energies are present, the limiting process coincides with the simple symmetric exclusion process.

description: Relation between two properties of linear difference equations with infinite delay is investigated: (i) exponential stability, (ii) $ł^p$-input $ł^q$-state stability (sometimes is called Perron's property). The latter means that solutions of the non-homogeneous equation with zero initial data belong to $ł^q$ when non-homogeneous terms are in $ł^p$. It is assumed that at each moment the prehistory (the sequence of preceding states) belongs to some weighted $ł^r$-space with an exponentially fading weight (the phase space). Our main result states that (i) $\Leftrightarrow$ (ii) whenever $(p,q) \neq (1,\infty)$ and a certain boundedness condition on coefficients is fulfilled. This condition is sharp and ensures that, to some extent, exponential and $ł^p$-input $ł^q$-state stabilities does not depend on the choice of a phase space and parameters $p$ and $q$, respectively. $ł^1$-input $ł^\infty$-state stability corresponds to uniform stability. We provide some evidence that similar criteria should not be expected for non-fading memory spaces.

description: Let $(M,g)$ be a compact Riemannian manifold on which a trace-free and divergence-free $σ\in W^{1,p}$ and a positive function $τ\in W^{1,p}$, $p > n$, are fixed. In this paper, we study the vacuum Einstein constraint equations using the well known conformal method with data $σ$ and $τ$. We show that if no solution exists then there is a non-trivial solution of another non-linear limit equation on $1$-forms. This last equation can be shown to be without solutions no solution in many situations. As a corollary, we get existence of solutions of the vacuum Einstein constraint equation under explicit assumptions which in particular hold on a dense set of metrics $g$ for the $C^0$-topology.

description: We experimentally show that exchange magnons can be detected using a combination of spin pumping and inverse spin-Hall effect (iSHE) proving its wavelength integrating capability down to the sub-micrometer scale. The magnons were injected in a ferrimagnetic yttrium iron garnet film by parametric pumping and the iSHE-induced voltage was detected in an attached Pt layer. The role of the density, wavelength, and spatial localization of the magnons for the spin pumping efficiency is revealed. This study opens the field of the magnon-based information processing to magnons with nano-scale wavelengths.

description: We show the potential of the LHC to detect a CP-even Higgs boson of the NMSSM, $h_1$ or $h_2$, decaying into two rather light CP-odd Higgs bosons, $a_1$, by exploiting the production mode based on Higgs-strahlung off $b$-quarks, i.e., the channel $pp\to b\bar b h_{1,2}$. We also consider the case of $h_2\to h_1 h_1$ decays. It is found that these decays have dominant BRs over large regions of the NMSSM parameter space where tan$β$ is large, a condition which also favours the $pp\to b\bar b h_{1,2}$ production rates. Further decays of the light Higgs boson pairs ($a_1$ and $h_1$) into photon, muon, tau and $b$ final states are also considered. The overall production and decay rates for these processes at inclusive level are sizable and should help extracting at least one Higgs boson signal over the NMSSM parameter space.

Deep endometriosis is defined as an endometriotic lesion penetrating to a depth of 5 mm or more, and is characterized by both fibrosis (forming nodules) and invasion (into structures such as the colon). Other groups have found that increased plasminogen activator inhibitor-1 (PAI-1) or (SERPINE1) expression was associated with fibrosis and tumor invasion. In addition, a previous study found that the SERPINE1 4G allele (and thus increased gene expression) was associated with increased pain in women with endometriosis, and other work suggested that SERPINE1 may be implicated in local neurogenesis. The objective of this thesis is to determine whether PAI-1 expression is associated with a) deep infiltrating endometriosis; and b) deep dyspareunia. We propose that increased PAI-1 expression will be associated with deep infiltrating endometriosis, and increased pain in endometriosis via an increase in local nerve fibers. We utilized immunohistochemical analysis using a validated PAI-1 antibody. In the first cohort, we examined PAI-1 expression in deep infiltrating endometriosis and compared to endometrioma, superficial endometriosis, and eutopic endometrium. In the second cohort, we examined PAI-1 expression in cul-de-sac endometriosis from women with or without deep dyspareunia. We found higher expression of PAI-1 in deep infiltrating endometriosis (n = 10) compared to superficial endometriosis (n = 10) (p = 0.031) and eutopic endometrium (n = 10) (p = 0.002). In the second cohort, we found lower expression of PAI-1 in women with more severe deep dyspareunia (r = - 0.352, n =35, p = 0.038). However, there was no association between PAI-1 expression and local nerve bundle density. In conclusion, we observed higher PAI-1 expression in deep infiltrating endometriosis, but lower PAI-1 expression in endometriosis from women with deep dyspareunia. Further research is needed to clarify the complexities of PAI-1 expression in endometriosis.

description: In this communication we address some hydrodynamic aspects of recently revisited drift mechanism of biogenic mixing in the ocean (Katija and Dabiri, Nature vol. 460, pp. 624-626, 2009). The relevance of the locomotion gait at various spatial scales with respect to the drift is discussed. A hydrodynamic scenario of the drift based on unsteady inertial propulsion, typical for most small marine organisms, is proposed. We estimate its effectiveness by taking into account interaction of a swimmer with the turbulent marine environment. Simple scaling arguments are derived to estimate the comparative role of drift-powered mixing with respect to the turbulence. The analysis indicates substantial biomixing effected by relatively small but numerous drifters, such as krill or jellyfish.

description: High-latitude processes and polar cloud microphysics envelop research areas the furtherance of which in the more accurate description of the arctic energy budget, climate variability, and feedbacks is essential. This study develops and assesses a multifrequency and Doppler-inclusive, ice particle size distribution retrieval technique for mean mass-weighted diameter and ice water content, and additionally proposes a radaronly, moment-based phase partition scheme tailored to polar regions. The technique is applied to datasets collected by the ARM research facility at the North Slope of Alaska and two ARM Mobile Facility 2 campaigns (BAECC, AWARE) that comprise a gamut of ground-based profiling sensors including radars at X, Ka, and W bands, lidar, and microwave radiometer. The microphysical retrieval is a multi-instrument task; firstly, a Ka-band -based, reflectivity-velocity power-law scheme estimates an ice sedimentation velocity corrected for the vertical wind component. An attenuation correction is then applied for the estimation of effective reflectivities. Both reflectivity and sedimentation velocity are integrated in a Bayesian scheme that compares observations against lookup- tables in both backscattering and hydrodynamic ice-particle properties. The radar only, phase partitioning is proven reliable in detecting cloud-top supercooled liquid water layers. Aggregate statistics are computed based on BAECC data. The combined utilization of radar reflectivity in a dual- or triple-frequency forward modeling in conjunction with sedimentation velocity, demonstrates that Doppler observations can assist in microphysical characterizations because connections across observations and simulations of both ice scattering and hydrodynamic properties are less ambiguous compared to scattering-only. Results demonstrate less retrieval spread among X / Ka / W / Doppler or Ka / W / Doppler retrieval scenarios as opposed to X / Ka / W. Lastly, the inclusion of a lower frequency (10-15 GHz) is advocated due to its significance in signal mitigation (attenuation, cross-calibration) and in the retrieval forward modeling ambiguity constraining.

description: An incomplete particle identification distorts the observed event-by-event fluctuations of the hadron chemical composition in nucleus-nucleus collisions. A new experimental technique called the {\em identity method} was recently proposed. It eliminated the misidentification problem for one specific combination of the second moments in a system of two hadron species. In the present paper this method is extended to calculate all the second moments in a system with arbitrary number of hadron species. Special linear combinations of the second moments are introduced. These combinations are presented in terms of single-particle variables and can be found experimentally from the event-by-event averaging. The mathematical problem is then reduced to solving a system of linear equations. The effect of incomplete particle identification is fully eliminated from the final results.

description: We study simultaneous X-ray and optical observations of three intermediate polars EX Hya, V1223 Sgr and TV Col with the aim to understand the propagation of matter in their accretion flows. We show that in all cases the power spectra of flux variability of binary systems in X-rays and in optical band are similar to each other and the majority of X-ray and optical fluxes are correlated with time lag <1 sec. These findings support the idea that optical emission of accretion disks, in these binary systems,largely originates as reprocessing of X-ray luminosity of their white dwarfs. In the best obtained dataset of EX Hya we see that the optical lightcurve unambiguously contains some component, which leads the X-ray emission by ~7 sec. We interpret this in the framework of the model of propagating fluctuations and thus deduce the time of travel of the matter from the innermost part of the truncated accretion disk to the white dwarf surface. This value agrees very well with the time expected for matter threaded onto the magnetosphere of the white dwarf to fall to its surface. The datasets of V1223 Sgr and TV Col in general confirm these findings,but have poorer quality.

description: It is becoming clear that the atmospheres of the young, self-luminous extrasolar giant planets imaged to date are dusty. Planets with dusty atmospheres may exhibit detectable amounts of linear polarization in the near-infrared, as has been observed from some field L dwarfs. The asymmetry required in the thermal radiation field to produce polarization may arise either from the rotation-induced oblateness or from surface inhomogeneities, such as partial cloudiness. While it is not possible at present to predict the extent to which atmospheric dynamics on a given planet may produce surface inhomogeneities substantial enough to produce net non-zero disk integrated polarization, the contribution of rotation-induced oblateness can be estimated. Using a self-consistent, spatially homogeneous atmospheric model and a multiple scattering polarization formalism for this class of exoplanets, we show that polarization on the order of 1% may arise due to the rotation-induced oblateness of the planets. The degree of polarization for cloudy planets should peak at the same wavelengths at which the planets are brightest in the near-infrared. The observed polarization may be even higher if surface inhomogeneities exist and play a significant role. Polarized radiation from self-luminous gas giant exoplanets, if detected, provides an additional tool to characterize these young planets and a new method to constrain their surface gravity and masses.

description: Photonic structures manipulate the propagation of light by scattering and interference effects. We fabricate and optically characterise high-quality three-dimensional photonic quasicrystals operating at infrared frequencies. They mimic a diffusive behaviour usually known from disordered systems, due to multiple scattering of light. We study icosahedral quasicrystals, known from electronic systems, in both experiment and theory, as well as rhombicuboctahedral ones, a novel class introduced by us.

description: In the wake of the COVID-19 pandemic, vaccines have been pivotal in curbing disease spread and severity. However, concerns over post-vaccination adverse events, including uveitis, an inflammatory ocular condition, have been noted. This systematic review and meta-analysis aimed to evaluate the incidence and association of uveitis following COVID-19 vaccination. A literature search was performed across several databases on October 21, 2023. Human studies examining the incidence of uveitis post-COVID-19 vaccination were included. The Newcastle-Ottawa Scale was used for quality appraisal of the included studies. Meta-analysis was performed to assess the overall incidence of uveitis and the relative risk of developing the condition post-vaccination. All statistical analyses were performed using R software version 4.3. Six studies involving over 2 billion vaccine doses were included. The overall incidence of uveitis was 0.016% (95% CI: 0.010 to 0.026). No significant association was found between vaccination and the onset of uveitis (Relative Risk: 1.45 (95% CI: 0.82 to 2.57, p = 0.12) from four studies. The evidence quality was rated very low due to the limited number of studies and imprecision. This analysis indicates a low incidence of uveitis following COVID-19 vaccination and no significant association with the vaccine. The findings are constrained by the small number of studies and low certainty of evidence, underscoring the need for further research. Comprehensive and longitudinal studies are necessary to confirm these findings and reinforce public confidence in COVID-19 vaccination programs.
