Conversion of BaF₂ to BaO for in-situ growth of Y-Ba-Cu-O thin films
Creators: name: Gao, Yuan
Publisher: name: University of British Columbia
Year: 2010

description: The Y₁Ba₂Cu₃0x superconducting thin films were made by both sequential electron-beam evaporation and co-evaporation of Cu, BaF₂ and Y, followed with high temperature post-deposition annealing. The possibility of making Y₁Ba₂Cu₃0x superconducting film in situ with BaF₂ as the Ba source was investigated by studying the conditions of in situ conversion of BaF₂ to BaO. The BaO concentration in the film as function of the substrate temperature was estimated with an equilibrium thermodynamic model and found to agree with the experimental results. A brief experimental and theoretical exploration of BaCl₂ also showed that BaCl₂ does not have any advantage over BaF2 as the Ba source for in situ growth of Y-Ba-Cu-0 films from the growth temperature point of view.

description: We develop a new method for the statistical esitmation of the tail of the distribution of earthquake sizes recorded in the Worldwide Harvard catalog of seismic moments converted to mW-magnitudes (1977-2004 and 1977-2006). We show that using the set of maximum magnitudes (the set of T-maxima) in windows of duration T days provides a significant improvement over existing methods, in particular (i) by minimizing the negative impact of time-clustering of foreshock / main shock /aftershock sequences in the estimation of the tail of the magnitude distribution, and (ii) by providing via a simulation method reliable estimates of the biases in the Moment estimation procedure (which turns out to be more efficient than the Maximum Likelihood estimation). Using a simulation method, we have determined the optimal window size of the T-maxima to be T=500 days. We have estimated the following quantiles of the distribution of T-maxima of earthquake magnitudes for the whole period 1977-2006: Q_{0.16}(Mmax)=9.3, Q_{0.5}(Mmax)=9.7 and Q_{0.84}(Mmax)=10.3. Finally, we suggest two more stable statistical characterristics of the tail of the distribution of earthquake magnitudes: the quantile QT(q) of a high probability level q for the T-maxima, and the probability of exceedence for a high threshold magnitude. We obtained the following sample estimates for the global Harvard catalog: QT(q=0.98)=8.6 +- 0.2 and a probability for the T-maxima to exceed magnitude 8 equal to 0.13-0.20. The comparison between our estimates for the two periods 1977-2004 and 1977-2006, where the later period includes the great Sumatra earthquake, 24.12.2004, mW=9.0, confirms the instability of the estimation of the parameter Mmax and the stability of the two other estimates.

description: Let $β$ be a braid on $n$ strands, with exponent sum $w$. Let $Δ$ be the Garside half-twist braid. We prove that the coefficient of $v^{w-n+1}$ in the Homfly polynomial of the closure of $β$ agrees with $(-1)^{n-1}$ times the coefficient of $v^{w+n^2-1}$ in the Homfly polynomial of the closure of $βΔ^2$. This coincidence implies that the lower Morton--Franks-Williams estimate for the $v$--degree of the Homfly polynomial of $\hatβ$ is sharp if and only if the upper MFW estimate is sharp for the $v$--degree of the Homfly polynomial of $\hat{βΔ^2}$.

Mathematical models of immunity
Creators: name: Mathewson, Donald Jeffrey
Publisher: name: University of British Columbia
Year: 2010

description: A cross-linking model for the activation of the A cell or immune accessory cell as a function of certain extracellular conditions is developed to determine the valency of the specific factor receptor on the A cell surface. It is found that such a determination can be made based on the FWHM of cross-linking curves which differ by a full order of magnitude between the bivalent receptor case and the monovalent receptor case. This determination can be made provided one can obtain accurate values for the equilibrium constants which characterize the system and provided that activation and IL-1 secretion is a linear function of cross-linking. It is also found that a determination of valence can be made if the equilibrium constants are such that substantial one receptor bridge formation takes place (one antibody molecule bound on both ends by the same receptor). This one-receptor bridge formation only takes place if the receptor is bivalent, and it presents itself in the cross-linking curve in a very distinctive manner. A second network model described as an ecological competition model of steady state lymphocyte populations is presented. This model, known as the symmetrical network theory is analysed numerically by integration of the differential equations and shown to provide a reasonable qualitative picture of the immune system's stable steady states, and offer a glimpse of state switching.

description: COVID-19 drastically increased demand- and supply pressures faced by healthcare systems. Increased pressures may have negative spillovers into non COVID-19 care which can cause preventable excess deaths among patients seeking medical help for reasons unrelated to COVID-19. This paper finds substantial and robust evidence of such non COVID-19 excess deaths among hospital patients leveraging data from an integrated public healthcare system: the NHS in England. We find that there is at least one additional preventable death among hospital patients seeking medical help for reasons unrelated to COVID-19 for every 30 deaths that can be linked to COVID-19. In aggregate, there were 4,003 such excess deaths during the first twelve months of the pandemic. At the healthcare provider level, the increase in non COVID-19 excess deaths is sharply increasing in COVID-19 induced pressures on hospitals.

description: We study two dimensional Fabry-Perot interferometric observations of the nearby face-on late-type spiral galaxy, NGC 628, in order to analyse the ionized gas component of the interstellar medium. Covering the galaxy out to a radius larger than 12 kpc, and with a spatial sampling of 1.6 arcsec, we investigate the large-scale dynamics as well as feedback from individual HII regions into their surrounding medium. We study the role of gravitational perturbations along with that of external triggers which can disturb the kinematics and morphology of NGC 628. We verify the presence of an inner rapidly rotating disc-like component in NGC 628, which we interpret as caused by slow secular evolution of the large-scale spiral arms and oval structure. In combination with auxiliary data, we find indication for that gas is falling in from the outer parts towards the central regions, where a nuclear ring has formed at the location of the inner Lindblad resonance radius of an m=2 perturbation which could help build a pseudo-bulge in NGC 628. Moreover, we calculate radial profiles of the emission-line velocity dispersion which we use to study the role of feedback from individual HII regions. The mean velocity dispersion for the ionized gas (even when excluding pixels belonging to individual HII regions) is almost constant out to 12 kpc, although it varies from 14 to 20 km/s, with a steady decline in the outer parts. The current paper demonstrates a number of tools that we have developed for building a solid frame work for studying the evolution of structure in spiral galaxies using two dimensional kinematic observations.

LLMs as Semantic Telescopes: A Framework for Contextual Coherence and Cognitive Grounding
Creators: name: Devine, Matthew
Publisher: name: Zenodo
Year: 2025

description: This paper proposes that large language models (LLMs) are best understood not as knowledge oracles, but as 'semantic telescopes'—tools that allow users to navigate, magnify, and resolve structures within a vast symbolic field (Ψ). Like telescopes require trained eyes and astronomical knowledge to interpret what is seen, LLMs require internal coherence, intellectual preparation, and recursive symbolic capacity in the user to perceive insight rather than hallucination. Drawing on Recursive Coherence Collapse (RCC), predictive processing, and phenomenological models of mind, we argue that the interpretive power of LLMs is not intrinsic but emerges from the recursive architecture of the user.
Evaluating the relationship between mindfulness and response to a single session repetitive negative thinking intervention
Creators: name: St. Denis, Molly
Publisher: name: No Publisher Supplied
Year: 2022

description: Repetitive negative thinking (RNT) is a transdiagnostic construct defined as cognitive perseveration on negative themes (e.g., worry and rumination), and has been implicated in the etiology and maintenance of various psychological disorders. Studies have shown that reductions in RNT may mediate the initial and sustained reductions in symptoms of anxiety and depression, among other disorders. Mindfulness-based interventions have been shown to effectively reduce RNT, however many existing treatments are time-consuming and resource-intensive. Thus, brief, mindfulness skills video interventions that target the transdiagnostic elements of RNT are a promising new area of exploration. Since research is limited regarding factors that predict response to such interventions, the current study explored the effect of baseline mindfulness skills on participants’ response to a single session, mindfulness video intervention. Data from 76 adult community members high in RNT were collected to measure RNT levels and mindfulness skills prior to watching a one-session mindfulness skills training video, as well as RNT levels five days after watching the video. Results indicated that several facets of mindfulness were negatively correlated with pre-intervention RNT levels. However, only one facet related to taking a non-evaluative stance toward internal thoughts and feelings moderated participants’ response to the intervention; those with lower non-judgmental awareness skills had a significantly greater decrease in PTQ scores following the intervention than those who scored higher on non-judgmental awareness. Results have implications for predicting response to easily accessible mindfulness-based interventions that address the shared, transdiagnostic elements of RNT, which will allow for more targeted treatment recommendations.

description: Radio-quiet gamma-ray pulsars like Geminga may account for a number of the unidentified EGRET sources in the Galaxy. The number of Geminga-like pulsars is very sensitive to the geometry of both the gamma-ray and radio beams. Recent studies of the shape and polarization of pulse profiles of young radio pulsars have provided evidence that their radio emission originates in wide cone beams at altitudes that are a significant fraction (1 -10%) of their light cylinder radius. Such wide radio emission beams will be visible at a much larger range of observer angles than the narrow core components thought to originate at lower altitude. Using 3D geometrical modeling that includes relativistic effects from pulsar rotation, we study the visibility of such radio cone beams as well as that of the gamma-ray beams predicted by slot gap and outer gap models. From the results of this study one can obtain revised predictions for the fraction of Geminga-like, radio quiet pulsars present in the gamma-ray pulsar population.

description: We report on our analysis of a 20 ksec Chandra X-ray observation of the quasi-persistent neutron star soft X-ray transient (SXT) 1M1716-315 in quiescence. Only one source was detected in the HEAO-I error region. Its luminosity is 1.6E32-1.3E33 erg s-1. In this the range is dominated by the uncertainty in the source distance. The source spectrum is well described by an absorbed soft spectrum, e.g. a neutron star atmosphere or black body model. No optical or near-infrared counterpart is present at the location of the X-ray source, down to a magnitude limit of I> 23.5 and K_s> 19.5. The positional evidence, the soft X-ray spectrum together with the optical and near-infrared non-detections provide strong evidence that this source is the quiescent neutron star SXT. The source is 10-100 times too bright in X-rays in order to be explained by stellar coronal X-ray emission. Together with the interstellar extinction measured in outburst and estimates for the source distance, the reported optical and near-infrared limit give an upper limit on the absolute magnitude of the counterpart of I>8.6 and K_s>5.1. This implies that the system is either an ultra-compact X-ray binary having P_orb<1 hr or the companion star is an M-dwarf. We reconstructed the long term X-ray lightcurve of the source. 1M1716-315 has been active for more than 12 years before returning to quiescence, the reported Chandra observation started 16.9+-4.1 years after the outburst ended.

description: A generalised notion of exponential families is introduced. It is based on the variational principle, borrowed from statistical physics. It is shown that inequivalent generalised entropy functions lead to distinct generalised exponential families. The well-known result that the inequality of Cramer and Rao becomes an equality in the case of an exponential family can be generalised. However, this requires the introduction of escort probabilities.

description: In the framework of the $^3P_0$ meson decay model, the strong decays of the $3 ^1S_0$ and $4 ^1S_0$ $s\bar{s}$ states are investigated. It is found that in the presence of the initial state mass being 2.24 GeV, the total widths of the $3 ^1S_0$ and $4 ^1S_0$ $s\bar{s}$ states are about 438 MeV and 125 MeV, respectively. Also, when the initial state mass varies from 2220 to 2400 MeV, the total width of the $4 ^1S_0$ $s\bar{s}$ state varies from about 100 to 132 MeV, while the total width of the $3 ^1S_0$ $s\bar{s}$ state varies from about 400 to 594 MeV. A comparison of the predicted widths and the experimental result of $(0.19\pm 0.03^{+0.04}_{-0.06})$ GeV, the width of the $η(2225)$ with a mass of $(2.24^{+0.03+0.03}_{-0.02-0.02})$ GeV recently observed by the BES Collaboration in the radiative decay $J/ψ\toγϕϕ\toγK^+K^-K^0_SK^0_L$, suggests that it would be very difficult to identify the $η(2225)$ as the $3 ^1S_0$ $s\bar{s}$ state, and the $η(2225)$ seams a good candidate for the $4 ^1S_0$ $s\bar{s}$ state.

description: We present the complete data set, model and line identification of a survey of the emission from the C-rich protoplanetary nebula CRL 618 performed with the IRAM-30m telescope in the following frequency ranges: 80.25-115.75 GHz, 131.25-179.25 GHz, and 204.25-275.250 GHz. A selection of lines from different species has been used in previous works to derive the structure of the source, its physical conditions and the chemical abundances in the different gas regions. In this work, we have used this information to run a global simulation of the spectrum in order to check the consistency of the model and to ease the task of line identification. The total number of lines that have a correspondence in both data and model is ~3100, although quite often in this object many lines blend into complex features so that the model, that takes into account line blending, is a key tool at this stage of the analysis. Of all the lines that we have been able to label, ~55% of them belong to the different forms of HC3N, and ~18% to those of HC5N. The density of remaining unidentified features above the 3sigma limit is only one per ~2.1 GHz (74 features), which is unprecedented in the analysis of this type of large millimeter-wave line surveys.

A study of laser plasma interactions in a cylindrical cavity
Creators: name: McKenna, RossAllan D.
Publisher: name: University of British Columbia
Year: 2010

description: A CO₂ laser system delivering a 12 J pulse with a FWHM of 2 ns on target was developed to serve as a driver for studies of laser plasma interactions within a cylindrical cavity. The system consisted of a hybrid oscillator, followed by an amplifier chain, and it achieved its design goals of delivering an intense CO₂ pulse, Gaussian in time and space, with a high contrast ratio on a reliable basis. The targets in which the plasma was produced consisted of small rectangular plates of lucite, with holes drilled through one of the long axes. The holes were 350 μm to 600 μm in diameter, and 10 mm in length. These dimensions allowed the laser beam, focused at the entrance of the hole, to produce sufficient intensity on the inner walls of the cylindrical cavity for plasma formation, while allowing the beam, with a waist diameter of 100 μm at the focus to deliver most of its energy within the cavity. The beam propagated via multiple reflections from the plasma through the cavity. Diagnostics were performed on the beam transmitted through the target. Streak camera images were collected of the intensity of visible emission from the plasma along the axis of the target. Anomalous results were obtained with respect to the reproducible observation of maximum visible light emission from regions at the far end cavity from where the laser beam is injected. Another unforseen but interesting result was the small divergence of the beam transmitted through the cavity. Preliminary models were developed to attempt to explain the observations.

description: We introduce for SU(2) quantum spin systems the Valence Bond Entanglement Entropy as a counting of valence bond spin singlets shared by two subsystems. For a large class of antiferromagnetic systems, it can be calculated in all dimensions with Quantum Monte Carlo simulations in the valence bond basis. We show numerically that this quantity displays all features of the von Neumann entanglement entropy for several one-dimensional systems. For two-dimensional Heisenberg models, we find a strict area law for a Valence Bond Solid state and multiplicative logarithmic corrections for the Neel phase.

Dialectical behavior therapy skills training for emotional problem solving for adolescents (DBT STEPS-A) in urban school contexts: a mixed methods study
Creators: name: Panish, Devora S.
Publisher: name: No Publisher Supplied
Year: 2022

description: The global population's rising mental health needs have resulted in myriad efforts to increase accessibility to intervention and support services, particularly those offered in school settings. Researchers and practitioners are increasingly exploring novel approaches to prevent and reduce the likelihood of mental health issues rather than its traditional emphasis on intervening when problems have already emerged. The recently developed Dialectical Behavior Therapy Skills Training for Emotional Problem Solving for Adolescents (DBT STEPS-A) is an extension of the empirically-supported DBT interventions and in effect, brings strong clinical therapy to universal school settings. The current study utilizes a mixed-methods research design to explore a pilot implementation of DBT STEPS-A in an urban public school context across two sixth grade student cohorts (i.e., Study 1 and Study 2). Three broad research questions addressed students’ quantitative gain scores and two qualitative dimensions of social validity (i.e., perceived acceptability and importance of effects). Although most data was collected for only Study 1 students, information pertaining to students’ social validity perceptions of DBT STEPS-A’s effects was gathered from both student cohorts at distinct data collection points. Based on the analyses conducted, results revealed no statistically significant improvements in students’ overall psychopathology and emotion regulation scores at post-intervention. However, qualitative analysis of social validity data regarding student perceptions of the importance of DBT STEPS-A revealed that both Study 1 and Study 2 students perceived beneficial outcomes over the course of the intervention including improvements in their emotion regulation skills. In addition, qualitative data suggested that Study 1 students perceived several DBT STEPS-A's activities and/or procedures as acceptable, although many suggestions were made for improving and enhancing this intervention. Study findings highlight the importance of acquiring competencies related to designing and implementing SEL programs, while considering student voice. Study findings contribute to DBT STEPS-A's preliminary program implementation literature and provide insight as to the initial effectiveness and social validity of the intervention including the perceived core desirable features of DBT STEPS-A and the importance of their effects among urban, low-income middle school students. Implications and limitations of this study are recognized.

description: The electronic reconstruction at the interface between two insulating oxides can give rise to a highly-conductive interface. In analogy to this remarkable interface-induced conductivity we show how, additionally, magnetism can be induced at the interface between the otherwise nonmagnetic insulating perovskites SrTiO3 and LaAlO3. A large negative magnetoresistance of the interface is found, together with a logarithmic temperature dependence of the sheet resistance. At low temperatures, the sheet resistance reveals magnetic hysteresis. Magnetic ordering is a key issue in solid-state science and its underlying mechanisms are still the subject of intense research. In particular, the interplay between localized magnetic moments and the spin of itinerant conduction electrons in a solid gives rise to intriguing many-body effects such as Ruderman-Kittel-Kasuya-Yosida (RKKY) interactions, the Kondo effect, and carrier-induced ferromagnetism in diluted magnetic semiconductors. The conducting oxide interface now provides a versatile system to induce and manipulate magnetic moments in otherwise nonmagnetic materials.

description: We consider higher-order QCD corrections to the production of colourless high-mass systems (lepton pairs, vector bosons, Higgs bosons,...) in hadron collisions. We propose a new formulation of the subtraction method to numerically compute arbitrary infrared-safe observables for this class of processes. To cancel the infrared divergences, we exploit the universal behaviour of the associated transverse-momentum (q_T) distributions in the small-q_T region. The method is illustrated in general terms up to the next-to-next-to-leading order (NNLO) in QCD perturbation theory. As a first explicit application, we study Higgs boson production through gluon fusion. Our calculation is implemented in a parton level Monte Carlo program that includes the decay of the Higgs boson in two photons. We present selected numerical results at the LHC.

 This species has a broad distribution in East Asia, extending from continental Southeast Asia westward to Nepal, where it has been found between ca. 2,500 and 3,700 m above sea level (Clifford et al. 1975). In Southeast Asia it has been reported from Doi Inthanon in northern Thailand (Kitaoka and Suzuki 1983). In this area hosts of female ticks are the yellow-throated martin (Martes flavigula, which is also a host in Nepal), and larvae have been found on two rodents (Eothenomys melanogaster and Rattus sp.). Some biological information is available, chiefly from Japan (Fujimoto and Yamaguti 1990; Kawabuchi et al. 2005; Yamauchi et al. 2013).

description: Evidence for the accretion of cold gas in galaxies has been rapidly accumulating in the past years. HI observations of galaxies and their environment have brought to light new facts and phenomena which are evidence of ongoing or recent accretion: 1) A large number of galaxies are accompanied by gas-rich dwarfs or are surrounded by HI cloud complexes, tails and filaments. It may be regarded as direct evidence of cold gas accretion in the local universe. It is probably the same kind of phenomenon of material infall as the stellar streams observed in the halos of our galaxy and M31. 2) Considerable amounts of extra-planar HI have been found in nearby spiral galaxies. While a large fraction of this gas is produced by galactic fountains, it is likely that a part of it is of extragalactic origin. 3) Spirals are known to have extended and warped outer layers of HI. It is not clear how these have formed, and how and for how long the warps can be sustained. Gas infall has been proposed as the origin. 4) The majority of galactic disks are lopsided in their morphology as well as in their kinematics. Also here recent accretion has been advocated as a possible cause. In our view, accretion takes place both through the arrival and merging of gas-rich satellites and through gas infall from the intergalactic medium (IGM). The infall may have observable effects on the disk such as bursts of star formation and lopsidedness. We infer a mean ``visible'' accretion rate of cold gas in galaxies of at least 0.2 Msol/yr. In order to reach the accretion rates needed to sustain the observed star formation (~1 Msol/yr), additional infall of large amounts of gas from the IGM seems to be required.

description: We study the extinction efficiencies as well as scattering properties of particles of different porosity. Calculations are performed for porous pseudospheres with small size (Rayleigh) inclusions using the discrete dipole approximation. Five refractive indices of materials covering the range from $1.20+0.00i$ to $1.75+0.58i$ were selected. They correspond to biological particles, dirty ice, silicate, amorphous carbon and soot in the visual part of spectrum. We attempt to describe the optical properties of such particles using Lorenz-Mie theory and a refractive index found from some effective medium theory (EMT) assuming the particle is homogeneous. We refer to this as the effective model. It is found that the deviations are minimal when utilizing the EMT based on the Bruggeman mixing rule. Usually the deviations in extinction factor do not exceed $\sim 5%$ for particle porosity ${\cal P}=0 - 0.9$ and size parameters $x_{\rm porous} = 2 πr_{\rm s, porous}/λ\la 25$. The deviations are larger for scattering and absorption efficiencies and smaller for particle albedo and asymmetry parameter. Our calculations made for spheroids confirm these conclusions. Preliminary consideration shows that the effective model represents the intensity and polarization of radiation scattered by fluffy aggregates quite well. Thus, the effective models of spherical and non-spherical particles can be used to significantly simplify computations of the optical properties of aggregates containing only Rayleigh inclusions.

description: We investigate how the Unitary Correlation Operator Method (UCOM), developed to explicitly describe the strong short-range central and tensor correlations present in the nuclear many-body system, relates to the Similarity Renormalization Group (SRG), a method to band-diagonalize Hamiltonians by continuous unitary transformations. We demonstrate how the structure of the UCOM transformation, originally motivated from the physically intuitive picture of correlations in coordinate space, arises naturally from the SRG flow equation. Apart from formal considerations we show that the momentum space matrix elements of the effective interactions obtained in both schemes agree extremely well.

Mentalization-based group intervention for parents of children with attention-deficit/hyperactivity disorder
Creators: name: Silber, Madelyn J.
Publisher: name: No Publisher Supplied
Year: 2022

description: Attention-Deficit/Hyperactivity Disorder (ADHD) affects 6.1 million children and adolescents in the United States (Conway, 2015) and 7.2% of the worldwide population (Thomas et al., 2015). Typically diagnosed in childhood, ADHD is a lifelong disorder that is associated with significant negative effects in adulthood. Treatment for ADHD commonly focuses on observable symptoms of inattention and impulsivity, yet this disorder is also associated with difficulties in the ability to mentalize or understand reactions and behaviors of the self and others as motivated by feelings and intentions. Parents of children with ADHD also have more difficulties with mentalization than non-ADHD parents (Johnston, Hommersen, and Seipp, 2009; Mazzeschi et al., 2019). This particular deficit can cause significant challenges in the parent/child relationship. Outcome data from one of the largest ADHD treatment studies identified the need for interventions with longer-term treatment gains and the essential need to intervene at the level of parenting (Hinshaw and Arnold, 2015). The following intervention seeks to fill this need by providing a protocol for a mentalization-based group intervention for parents of children with ADHD with the goals of providing psychoeducation about ADHD and the concept of mentalization, helping parents better identify when breakdowns in mentalization occur in their interactions with their child, and recognizing and fostering mentalization in their child to ultimately improve the parent/child relationship and reduce the child’s ADHD symptoms. Outcome measures are included to study the effectiveness of this intervention at the Cultivating Compassion Project, the psychodynamic ADHD clinic at Rutgers University’s Center for Psychological Services.
ESR study of DMTM(TCNQ)₂

description: The ESR g-value and susceptibility measurements for DMTM(TCNQ)₂ have been studied as a function of angle made by crystal with magnetic field and temperature. The angular dependence of g-value is fitted to g² = α+βcos2θ - γsin2θ for three orthogonal directions of crystal rotation. The principal g-values are close to those expected for TCNQ compounds: g₁ = 2.0034, g₂ = 2.0030, g₃ = 2.0024. The susceptibility as a function of temperature agrees with bulk susceptibility measurements except that the maximum position occurs at about 30 K. The results of Oostra et al. for bulk susceptibility showed a maximum at around 50 K. The phase transition reported by Visser et al. at 272 K is observed in the ESR data as a 15% decrease in susceptibility. The linewidth is remarkably anisotropic typical of TCNQ salts. The phase transition study is done for two orientations of the crystal with the magnet field. In one of the orientations the linewidth narrows from 0.15 to 0.11 gauss and in the other it narrows from 0.24 to 0.18 gauss. In the former case there is a growth of a second line due to the twinned stack; transformation twinning takes place at the phase transition. A small level-crossing interaction is inferred from the change in relative intensities of the lines near the crossover.

description: Over the past two years, the search for low-mass extrasolar planets has led to the detection of seven so-called 'hot Neptunes' or 'super-Earths' around Sun-like stars. These planets have masses 5-20 times larger than the Earth and are mainly found on close-in orbits with periods of 2-15 days. Here we report a system of three Neptune-mass planets with periods of 8.67, 31.6 and 197 days, orbiting the nearby star HD 69830. This star was already known to show an infrared excess possibly caused by an asteroid belt within 1 AU (the Sun-Earth distance). Simulations show that the system is in a dynamically stable configuration. Theoretical calculations favour a mainly rocky composition for both inner planets, while the outer planet probably has a significant gaseous envelope surrounding its rocky/icy core; the outer planet orbits within the habitable zone of this star.

title: Acoustic signal-based underwater oil leak detection and localization
Creators: name: Kosanam Chandrasekar, Geetha Varsha
Publisher: name: Memorial University of Newfoundland
Year: 2021

description: Underwater Wireless Sensor Networks (UWSNs) have been becoming popular for exploring offshore, natural resource development, geological oceanography, and monitoring the underwater environment. The acoustic channel characteristics in underwater impose challenges, including limited bandwidth, signal attenuation, and propagation delay that limits UWSN utilization. The marine environment is under threat from pollution, which impacts human life and activities. Compared to other pollution types, the oil leak is a significant threat to the marine ecosystem. When the leaked oil or other petroleum products mix with water in the ocean, significant biological and economic impacts could result. Although much research has focused on improving the reception and processing of acoustic signals, increasing performance, and reducing packet delay, no significant research results have been reported on finding an effective early-stage leak detection method using acoustic signal processing. Accurate information about oil spill location and its characteristics is much needed for oil spill containment and cleanup operations. Developing an efficient under- water oil leak detection and localization algorithm is still challenging in UWSNs because of the impairments of the acoustic channel. In this thesis, we propose a technique that detects the presence of an oil leak in the underwater environment at an early stage. We also propose a localization algorithm that determines the approximate location of the oil leak. Firstly, we review the propagation properties of acoustic signals to understand acoustic communication in the marine environment better. We then discuss the transmission of sound in terms of reflection and refraction. We propose a leak detection technique based on the range estimation method to detect oil leak at an early stage before reaching the ocean sur- face. We perform a two-dimensional analysis for evaluating the performance of the proposed detection technique. To investigate the proposed technique, we perform evaluation with different network sizes and topologies. We discuss the detection ratio, network scalability, power and intensity of the received signal. We then perform a three-dimensional analysis to evaluate the performance of the proposed technique. We conduct theoretical analysis to investigate the proposed technique in terms of detection ratio, network scalability, power and intensity of the received signal. We assess the efficiency of the proposed detection method by considering an oil leak at different ocean levels. Finally, we propose a cooperative localization algorithm for localizing the leak in the UWSN. We then evaluate the proposed localization algorithm for two different topologies. Our results show that our proposed technique works well for an underwater network with concentric hexagonal topology. We can extend the proposed method for other types of targets with different shapes and sizes.

description: The Euler equation (EE) is one of the basic equations in many physical fields such as fluids, plasmas, condensed matter, astrophysics, oceanic and atmospheric dynamics. A symmetry group theorem of the (2+1)-dimensional EE is obtained via a simple direct method which is thus utilized to find \em exact analytical \rm vortex and circumfluence solutions. A weak Darboux transformation theorem of the (2+1)-dimensional EE can be obtained for \em arbitrary spectral parameter \rm from the general symmetry group theorem. \rm Possible applications of the vortex and circumfluence solutions to tropical cyclones, especially Hurricane Katrina 2005, are demonstrated.

description: Στόχος της παρούσας διατριβής ήταν η ανάπτυξη μιας μεθοδολογίας για την εκτίμηση της τοξικότητας σωματιδιακών εκπομπών από οχήματα. Για το σκοπό αυτό συλλέχθηκαν δείγματα σωματιδιακής ύλης, από πέντε διαφορετικά οχήματα, σε εναιωρήματα και σε φίλτρα. Τα δείγματα αναλύθηκαν, ώστε να προσδιοριστεί η χημική τους σύσταση. Επιπρόσθετα, προσδιορίστηκαν τα φυσικά χαρακτηριστικά του αερολύματος. Στη συνέχεια τα δείγματα χρησιμοποιήθηκαν σε διάφορες τοξικολογικές αναλύσεις. Η μεθοδολογία καταλήγει με το συσχετισμό των τοξικολογικών αναλύσεων με τα φυσικά και χημικά χαρακτηριστικά των σωματιδιακών εκπομπών με στόχο την ανίχνευση κυρίαρχων συστατικών. Τα αποτελέσματα δείχνουν ότι υπάρχουν τουλάχιστον δύο μηχανισμοί τοξικότητας. Ο ένας οφείλεται στην οξειδοαναγωγική δράση βαρέων μετάλλων και ο άλλος στη δράση υδρογονανθράκων. Τέλος, αποκαλύπτεται ότι η φλεγμονώσης αντίδραση του οργανισμού δεν είναι γραμμική συνάρτηση της ποσότητας της δόσης.
description: The aim of the present thesis was the development of a methodology for the toxicity assessment of vehicular particle emissions. To this direction, water-borne particle samples were collected by employing five different vehicles. PM was also collected on filters. Afterwards, the samples were analyzed for the determination of the particle chemical composition. Moreover, the physical characteristics of the original aerosol were measured. In addition, the samples were used in various toxicity assays. The next step of the methodology was the determination of the correlations between the physical and chemical characteristics and the toxicological results. Results show that the underlying mechanisms are at least two, based on two major compound categories: heavy metals and poly-aromatic hydrocarbons. Finally, there is revealed that the inflammatory response of a living organism is not linearly related to the dose mass.
