Piezoresponse force microscopy using adaptive contact-mode imaging
Creators: name: Waskar, Mohit
Publisher: name: No Publisher Supplied
Year: 2019

description: Atomic Force Microscopy (AFM) is a type of Scanning Probe Microscopy (SPM) which involves a probe tip scanning over a sample surface for obtaining data of the sample. Data acquisition is carried out by making physical contact with the surface of the sample, thus there is scope of characterizing data even beyond basic topology. Piezoresponse Force Microscopy (PFM) is just an extension of AFM imaging which is used for obtaining the piezoelectric response of the sample using the converse piezoelectric effect. Piezoelectric effect can be observed in almost all the materials around us which include biological and inorganic materials. PFM imaging is extensively used in the nanoscale characterization of ferroelectrics and its applications continue to grow. Thus, with the growing use of this technique, it is important to obtain images of high quality and at a faster rate to reduce the time required to image without affecting its accuracy. Research and experiments show that with the help of different algorithms and external control, the speed of AFM imaging can be boosted with reduced loss of data and higher accuracy. This research aims at applying existing control methodologies used in AFM imaging to the PFM imaging and analyzing the output by comparing images obtained at lower and higher speeds using different methods.

description: Abstract
The purpose of this study is to analyze: 1) Why is law enforcement of the rights and obligations of the parties in the current credit agreement not fair? 2) How does the concept of progressive law apply justice to the rights and obligations of the parties to the credit agreement in the future? The research method used is normative juridical with a statutory approach, concept approach, and case studies. The results showed that: 1) Discussion on law enforcement is inseparable from the existence of legal relations between the Bank as a creditor and debtor customers. Legal relations can run improperly, such as one party or both parties violate agreements or agreements that have been mutually agreed. The position of the debtor customer is in a difficult position related to the legal relationship contained in the Bank Credit Agreement. It is said to be very difficult, because the debtor customer is the one who violates the juridical documents contained in the Bank Credit Agreement. 2) The entrance for the application of progressive law in judicial practice in Indonesia has been formally given by the Law on Judicial Power which affirms that the judicial power is tasked with upholding law and justice. In that order, judges are required to explore the values of law and justice that live in society. This means that judges are not just tasked with applying the rules as they are, but how they can bring about justice.

description: We present an analysis of high-resolution ($R \sim 50,000$) infrared K-band echelle spectra of 14 T Tauri stars in the Orion Nebula Cluster. We model Zeeman broadening in three magnetically sensitive \ion{Ti}{1} lines near $2.2\ μ$m and consistently detect kilogauss-level magnetic fields in the stellar photospheres. The data are consistent in each case with the entire stellar surface being covered with magnetic fields, suggesting that magnetic pressure likely dominates over gas pressure in the photospheres of these stars. These very strong magnetic fields might themselves be responsible for the underproduction of X-ray emission of T Tauri stars relative to what is expected based on main-sequence star calibrations. We combine these results with previous measurements of 14 stars in Taurus and 5 stars in the TW Hydrae association to study the potential variation of magnetic-field properties during the first 10 million years of stellar evolution, finding a steady decline in total magnetic flux with age.

description: Properties of Jost and dual Jost solutions of the heat equation, $Φ(x,k)$ and $Ψ(x,k)$, in the case of a pure solitonic potential are studied in detail. We describe their analytical properties on the spectral parameter $k$ and their asymptotic behavior on the $x$-plane and we show that the values of $e^{-qx}Φ(x,k)$ and the residua of $e^{qx}Ψ(x,k)$ at special discrete values of $k$ are bounded functions of $x$ in a polygonal region of the $q$-plane. Correspondingly, we deduce that the extended version $L(q)$ of the heat operator with a pure solitonic potential has left and right annihilators for $q$ belonging to these polygonal regions.

Genetic population structure, patterns of genetic variation, and patterns of phenotypic leaf variation among peripheral and core populations of the mangrove species Avicennia marina (Forsk.) Vierh. (Acanthaceae) on the red sea, Saudi Arabia.
Creators: name: Alharbi, Faisal Khalid G
Publisher: name: University of British Columbia
Year: 2018

description: This study utilized both of leaf dimension measurements (leaf area, length, maximal width, and the ratio of length: width) and 12 microsatellite loci screened across 315 samples of the entomophilous mangrove species Avicennia marina (Forsk.) Vierh. The samples collected from 9 sites along the Saudi Arabian Red Sea coastline with an estimated sampling range of 1,345 kilometres. The study objectives were to examine the genetic diversity, population structure, and the field observed phenotypic leaf variation, and to inspect the influence of the distribution limit on the genetic compositions and the phenotypic leaf traits variation. The 12 loci detected a total of 89 alleles with an average allelic diversity of 7.42. Observed heterozygosity (Hₒ) was close to expected heterozygosities (Hₑ) for most sites, and the average (Hₒ) was 0.298. The levels of inbreeding ranged from negative 0.044 to positive 0.126, with an average inbreeding coefficient of 0.012. The component of variation among populations were (25%, 34%) (p < 0.001), corresponding to the estimates of both FST and RST (0.25 and 0.34, respectively). The isolation by distance model (IBD) reflected the distribution of genetic variation with the existence of transitional zones and one distinct population at the farthest northerly edge of the geographic distribution. Significant differences in the various leaf characters occurred among the sites, which were explained by latitudes and inter-site distances. There was an obvious influence of the distribution limit mainly from Annual Sea Surface Temperature (SSTAnn) and Sea Surface Salinity in Winter (SW) on both of the genetic and morphological variations that manifested in a northwards declining trend for most gene diversity statistics and effective population size (Ne) mean values, and a northwards increasing tendency of leaf traits mean values and lower phenotypic variation. The morphological differentiation did not increase or decrease strictly based on the genetic differentiation among sites. However, the significant negative correlation between the mean values of leaf length and inbreeding coefficients suggested the occurrence of inbreeding depression in one site. Overall, the insights from this study imply the suitability of a geographically broad-scale conservative approach (100 km) to sourcing plant material for mangrove restoration projects.
Why Lense-Thirring solid-body precession cannot produce the LFQPOs observed in X-ray binaries

description: The timing properties of X-ray binaries are still not understood, particularly the presence of quasi-periodic oscillations (QPOs) in their X-ray power spectra. The solid-body regime of Lense-Thirring precession is one prominent model invoked to explain the most common type of QPOs, Type C. However, solid-body precession requires a specific structure that has not been examined in light of constrained properties of accretion flows. During this talk, I will explore the different observational constraints on the accretion flow and compare them to the structure required by the solid body precession. I will show that, in order to reproduce the observed X-ray spectra during luminous hard states, the hot flow must accrete at sonic to supersonic speeds, unreachable with typical viscous torques. As a result of this extreme accretion speed (or high α parameter), no region of the disk during these states lies in the "wave-like" regime required for solid-body precession. Furthermore, we expect the flow to align with the black hole spin axis via the Bardeen-Petterson effect inside a radius $r_break > r_t$. As a consequence, the hot inner flow cannot exhibit solid body precession - as currently pictured in the literature - during luminous hard states. Since Type C QPOs are prevalent in these states, we conclude that this mechanism is unlikely to be responsible for producing Type C QPOs around stellar mass black holes.

description: We study the spinless and spinful extended Hubbard models with repulsive interactions on the kagome and the decorated honeycomb ("star") lattice. Using Hartree-Fock mean-field theory, we show that interaction-driven insulating phases with non-trivial topological invariants (Chern number or $Z_2$ invariant) exist for an experimentally reasonable range of parameters. These phases occur at filling fractions which involve either Dirac points or quadratic band crossing points in the non-interacting limit. We present comprehensive mean-field phase diagrams for these lattices and discuss the competition between topologically non-trivial phases and numerous other ordered states, including various charge, spin, and bond orderings. Our results suggest that $Z_2$ topological insulators should be found in a number of systems with either little or no intrinsic spin-orbit coupling.

description: The Blandford-Znajek mechanism has long been regarded as a key ingredient in models attempting to explain powerful jets in AGNs, quasars, blazzars etc. In such mechanism, energy is extracted from a rotating black hole and dissipated at a load at far distances. In the current work we examine the behaviour of the BZ mechanism with respect to different boundary conditions, revealing the mechanism robustness upon variation of these conditions. Consequently, this work closes a gap in our understanding of this important scenario.

Coupled point neutron kinetics and thermal-hydraulics models of transient nuclear criticality excursions in wetted fissile uranium dioxide (UO2) powders
Creators: name: Jones, Gregory
Publisher: name: Imperial College London
Year: 2022

description: This thesis describes a phenomenologically based mathematical and computational methodology for the simulation of a postulated transient nuclear criticality excursion initiated by the incursion of water, from a fire-sprinkler system, into a bed of dry UO2 powder. These potentially hazardous multi-phase dispersed particulate systems may form as a result of a fire or explosion in a nuclear fuel fabrication facility. The models proposed in this thesis aim to support nuclear criticality safety analysis and assessment. In addition, the development of these models aims to support emergency planning and preparedness. The point neutron kinetics equations are coupled to phenomenological models of water infiltration, sedimentation, fluidisation, nuclear thermal hydraulics, radiolysis and boiling, through the use of multivariate reactivity feedback components. The spatial and temporal solution of this set of equations enables the modelling of postulated transient nuclear criticality excursions in highly dispersed three-phase particulate systems of UO2 powder. The results indicate that there is the potential for large positive reactivities to be added to a UO2 powder system as pores become filled with water. Generally, thermal expansion and Doppler broadening are insufficient to control the transient, leading to significant radiolysis and boiling on the surface of the UO2 powder particles. Radiolytic gas and steam bubble induced fluidisation and sedimentation significantly alters the characteristics of a transient nuclear criticality excursion and should be carefully considered. Research has also been undertaken examining transient nuclear criticality excursions in weak intrinsic neutron source UO2 powder systems by solving the forward probability balance equation and using a Gamma probability distribution function to estimate mean wait-time probability distributions. Significant variations in the potential initial peak power are predicted for highly enriched, wetted, UO2 powders as a function of the stochastic behaviour associated with criticality excursions in low neutron population systems.

Leveraging real-time patient experience data to improve healthcare delivery
Creators: name: Khanbhai, Mustafa
Publisher: name: Imperial College London
Year: 2021

description: Understanding the patient experience of healthcare is an essential element in providing patient-centric care. It is also a fundamental pillar of ensuring care quality. However, consistent application and utilisation of patient feedback is often inhibited by the unstructured nature of the data. For this reason a manual review is needed to extract insights. Our healthcare industry has invested heavily in recording, analysing and monitoring clinical outcomes data. However, relatively little emphasis has been placed on innovation in assessing patient experience to improve care delivery. This research addresses how can healthcare organisations can leverage real-time patient experience data to improve care delivery? In order to contribute a clear body of knowledge in response, this research ascertains the root cause of limited use of patient experience data; tests how novel analytic techniques can enhance data utliltiy; and explores how free-text experience data can be used to improve organisational responsiveness to patient feedback in real-time. First of all, this research systematically appraises the evidence on which designs of effective real-time feedback (RTF) systems are based. Four strategic themes are identified – namely, capacity/resource, usage, interoperability, and impact. These themes heavily influence the readiness and digital maturity of RTF systems, and it is recommended that healthcare services address the four themes individually in the design and implementation of RTF systems. Next, process mapping is employed to identify barriers and enablers of RTF and their effect on staff enagagement. Through interviews with healthcare stakeholders, opportunities for RTF to drive localised improvement are then identified. Secondly, this research leverages text analytics, namely Natural Language Processing (NLP), with supervised learning methods to analysed patient experience free-text data. Text (or theme) classification and sentiment analysis of the Friends and Family Test (FFT) free-text data, to a large extent, confirms the accuracy of the machine learning model. Furthermore, a co-design approach enables the FFT text analytics output to be displayed in a format in line with the interests of frontline staff and key stakeholders. A visualisation tool is deployed in combination with improvement models tested in various healthcare settings, selected by the most common themes and associated sentiment. This revitalised the benefits of hearing from patients in their own words by holding narrative data to the same standard of scientific rigour already applied to quantitative data. In addition, it reinforced staff to take action and address the most important patient concerns in a timely manner. Individually, these findings convey a series of policy recommendations, while cumulatively, they showcase the possibilities for a more patient-centric healthcare service.

description: The adsorption profiles and electronic structures of Pt$_n$ (n = 1--4) clusters on stoichiometric, reduced and reconstructed rutile TiO$_2$(110) surfaces were systematically studied using on site d-d Coulomb interaction corrected hybrid density functional theory calculations. The atomic structure of small Pt cluster adsorbates mainly depend on the stoichiometry of the corresponding titania support. The cluster shapes on the bulk terminated ideal surface look like their gas phase low energy structures. However, for instance, they get significantly distorted on the reduced surfaces with increasing oxygen vacancies. On non-stoichiometric surfaces, Pt--Ti coordination becomes dominant in the determination of the adsorption geometries. The electronic structure of Pt$_n$/TiO$_2$(110) systems can not be correctly described by pure DFT methods, particularly for non-stoichiometric cases, due to the inappropriate treatment of the correlation for $d$ electrons. We performed DFT+U calculations to give a reasonable description of the reconstructed rutile (110) surface. Pt clusters induce local surface relaxations that influence band edges of titania support, and bring a number of band-gap states depending on the cluster size. Significant band gap narrowing occurs upon Pt$_n$--surface interaction due to adsorbate driven states on the bulk terminated and reduced surfaces. On the other hand, they give rise to a band gap widening associated to partial reoxidation of the reconstructed surface. No metallization arises even for Pt$_4$ on rutile.

description: Some University historians indicate that the Targum was first published as an annual in 1867, but of this we have no extant evidence. In January 1869, the Targum as we now know it, made its appearance as a monthly paper that concerned itself with student “literary contributions” and college news as well as serving as a vehicle for bringing news to alumni and the general public. The newspaper, which originally was for sale, varied in frequency over the years as did its title (The Targum, Rutgers Targum, Rutgers Daily Targum, and Daily Targum). The newspaper has continuously been published since 1869 with the exception of 19 months during the second world war, between February 1944 and October 1945. The Targum was published by the students of Rutgers College, and later Rutgers University—New Brunswick represented through the years as the Targum Association, Rutgers Targum Association, and Rutgers College Targum. As a student organization, the Targum operated under the oversight of the dean of students and student government but in October 1980, the Targum became an independent college paper.

description: Recent high resolution observations of the Galactic center black hole allow for direct comparison with accretion disk simulations. We compare two-temperature synchrotron emission models from three dimensional, general relativistic magnetohydrodynamic simulations to millimeter observations of Sgr A*. Fits to very long baseline interferometry and spectral index measurements disfavor the monochromatic face-on black hole shadow models from our previous work. Inclination angles \le 20 degrees are ruled out to 3 σ. We estimate the inclination and position angles of the black hole, as well as the electron temperature of the accretion flow and the accretion rate, to be i=50+35-15 degrees, ξ=-23+97-22 degrees, T_e=(5.4 +/- 3.0)x10^10 K and Mdot=(5+15-2)x10^-9 M_sun / yr respectively, with 90% confidence. The black hole shadow is unobscured in all best fit models, and may be detected by observations on baselines between Chile and California, Arizona or Mexico at 1.3mm or .87mm either through direct sampling of the visibility amplitude or using closure phase information. Millimeter flaring behavior consistent with the observations is present in all viable models, and is caused by magnetic turbulence in the inner radii of the accretion flow. The variability at optically thin frequencies is strongly correlated with that in the accretion rate. The simulations provide a universal picture of the 1.3mm emission region as a small region near the midplane in the inner radii of the accretion flow, which is roughly isothermal and has ν/ν_c ~ 1-20, where ν_c is the critical frequency for thermal synchrotron emission.

description: Plasma turbulence is thought to be associated with various physical processes involved in solar flares, including magnetic reconnection, particle acceleration and transport. Using Ramaty High Energy Solar Spectroscopic Imager ({\it RHESSI}) observations and the X-ray visibility analysis, we determine the spatial and spectral distributions of energetic electrons for a flare (GOES M3.7 class, April 14, 2002 23$:$55 UT), which was previously found to be consistent with a reconnection scenario. It is demonstrated that because of the high density plasma in the loop, electrons have to be continuously accelerated about the loop apex of length $\sim 2\times 10^9$cm and width $\sim 7\times 10^8$cm. Energy dependent transport of tens of keV electrons is observed to occur both along and across the guiding magnetic field of the loop. We show that the cross-field transport is consistent with the presence of magnetic turbulence in the loop, where electrons are accelerated, and estimate the magnitude of the field line diffusion coefficient for different phases of the flare. The energy density of magnetic fluctuations is calculated for given magnetic field correlation lengths and is larger than the energy density of the non-thermal electrons. The level of magnetic fluctuations peaks when the largest number of electrons is accelerated and is below detectability or absent at the decay phase. These hard X-ray observations provide the first observational evidence that magnetic turbulence governs the evolution of energetic electrons in a dense flaring loop and is suggestive of their turbulent acceleration.

description: We present the construction and describe the properties of the Padova-Millennium Galaxy and Group Catalogue (PM2GC), a galaxy catalogue representative of the general field population in the local Universe. We characterize galaxy environments by identifying galaxy groups at 0.04<=z<=0.1 with a Friends-of-Friends (FoF) algorithm using a complete sample of 3210 galaxies brighter than MB = -18.7 taken from the Millennium Galaxy Catalogue (MGC, Liske et al. (2003)), a 38deg^2 photometric and spectroscopic equatorial survey. We identified 176 groups with at least three members, comprising in total 1057 galaxies and representing ~43 per cent of the general field population in that redshift range. The median redshift and velocity dispersion of our groups are 0.0823 and 192 km s^-1, respectively. 88 per cent of the groups have fewer than ten members, and 63 per cent have fewer than five members. Nongroup galaxies were subdivided into "inary" systems of two bright close companions, and "single" galaxies with no companion, in order to identify different environments useful for future scientific analysis. We performed a detailed comparison with the 2PIGG catalogue to validate the effectiveness of our method and the robustness of our results. Galaxy stellar masses are computed for all PM2GC galaxies, and found to be in good agreement with Sloan Digital Survey Data Release 7 (SDSS-DR7) mass estimates. The catalogues of PM2GC groups, group properties and galaxy properties in all environments are publicly available on theWorld Wide Web.

Simulations of stellar variability: the effect of magnetic features on rotational and transit lightcurves
Creators: name: Johnson, Luke Jonathan
Publisher: name: Imperial College London
Year: 2022

description: Stellar variability (on timescales of days or longer) results predominantly from surface manifestations of magnetic activity such as starspots and faculae, and is one of the most important limiting factors in the detection and characterisation of exoplanets. If variability amplitudes in time series photometry are sufficiently large, the periodic transit signature of an orbiting planet may go undetected. Spots and faculae occulted in-transit introduce line profile distortions to transit lightcurves, and the spectral contributions of unocculted features contaminate measured transmission spectra. Realistic models for magnetic features are required to understand and accurately constrain their effects. The implementation of faculae in lightcurve models for non-solar spectral types is an open problem, with scaling typically based on spectra equivalent to hot stellar atmospheres or assuming a solar-derived facular contrast. In this thesis, I introduce the stellar variability code actress, a software tool enabling geometrically-accurate rotational and transit lightcurve modelling. For the first time, synthetic spectra calculated from magneto-convection simulations for stellar spectral types other than solar are used as model inputs to represent the brightness contributions of the quiet stellar surface and facular regions. I use actress to simulate variability in Kepler and TESS observational passbands, examining the characteristic lightcurve signatures of individual features. Rotational lightcurves are generated with realistic Sun-like feature distributions to investigate how variability amplitudes are affected by changes in stellar parameters such as feature coverage level, emergence latitude, stellar inclination, facular region field strength, spot temperature contrast and activity level. The investigations are extended to wavelengths 240 nm − 10 μm, and both rotational variability and transit contamination are simulated throughout the full spectral range. Finally, I summarise the thesis findings and propose potential future investigations that complement and extend this line of research into stellar variability and transit lightcurve contamination.

description: In Haida Gwaii, the invasion of Sitka black-tailed deer (Odocoileus hemionus sitkensis) has decreased the abundance and diversity of plant communities, but little is known about their indirect effects on the activity, abundance, diversity and structure of soil fungal communities. In a natural experiment, I compared the edaphic properties, understory plants and soil fungi of deer-invaded and non-invaded islands. Soils on deer-invaded islands had significantly higher penetration resistance, higher phosphate concentrations and lower pH than soil on non-invaded islands. Understory plants on deer-invaded islands had significantly lower cover-abundance, higher species evenness and significant shifts in community composition, largely driven by differences in the abundances of Gaultheria shallon, Polystichum munitum, Lonicera involucrata and Menziesia ferruginea. Ergosterol, a biomarker of fungal biomass, was similar between deer-invaded and non-invaded islands. Illumina sequencing revealed significant differences in the species evenness and composition of the soil fungal community, but similar relative abundances of arbuscular mycorrhizal fungi, ectomycorrhizal fungi, ericoid mycorrhizal fungi and saprotrophic fungi between non-invaded and deer-invaded islands. Differences in the fungal community were significantly correlated with the cover-abundance of understory plants, the depth of the organic horizons, pH and concentrations of ammonium. In a greenhouse bioassay, Thuja plicata seedlings grown in living soils from deer-invaded islands had significantly lower chlorophyll fluorescence values (Fv/Fm), an indicator of plant stress, than seedlings grown in living soil from non-invaded islands, but there were no significant differences in the biomass, root:shoot ratios or the inoculum potential of arbuscular mycorrhizal fungi and dark septate endophytes in Thuja plicata. There were no significant differences in the biomass, root:shoot ratios, Fv/Fm values or inoculum potential of ectomycorrhizal fungi in Tsuga heterophylla grown in soils from deer-invaded and non-invaded islands. Fluorescence-based enzyme assays reveal significantly higher phosphatase activity, lower β-glucosidase and lower cellobiohydrolase activity in soils from deer-invaded islands. Through changes in the physiochemical soil properties and understory plant abundance, Sitka black-tailed deer initiate a cascade of indirect effects on the activity, diversity and composition of the soil fungal community.
MixRec: Individual and Collective Mixing Empowers Data Augmentation for Recommender Systems

description: The core of the general recommender systems lies in learning high-quality embedding representations of users and items to investigate their positional relations in the feature space. Unfortunately, data sparsity caused by difficult-to-access interaction data severely limits the effectiveness of recommender systems. Faced with such a dilemma, various types of self-supervised learning methods have been introduced into recommender systems in an attempt to alleviate the data sparsity through distribution modeling or data augmentation. However, most data augmentation relies on elaborate manual design, which is not only not universal, but the bloated and redundant augmentation process may significantly slow down model training progress. To tackle these limitations, we propose a novel Dual Mixing-based Recommendation Framework (MixRec) to empower data augmentation as we wish. Specifically, we propose individual mixing and collective mixing, respectively. The former aims to provide a new positive sample that is unique to the target (user or item) and to make the pair-wise recommendation loss benefit from it, while the latter aims to portray a new sample that contains group properties in a batch. The two mentioned mixing mechanisms allow for data augmentation with only one parameter that does not need to be set multiple times and can be done in linear time complexity. Besides, we propose the dual-mixing contrastive learning to maximize the utilization of these new-constructed samples to enhance the consistency between pairs of positive samples. Experimental results on four real-world datasets demonstrate the advantages of MixRec in terms of effectiveness, simplicity, efficiency, and scalability.

description: We conjecture that non-equilibrium boundary conditions generically trigger long range order in non-equilibrium steady states of locally interacting quantum chains. Our result is based on large scale density matrix renormalization group simulations of several models of quantum spin 1/2 chains which are driven far from equilibrium by coupling to a pair of unequal Lindblad reservoirs attached locally to the ends of the chain. In particular, we find a phase transition from exponentially decaying to long range spin-spin correlations in integrable Heisenberg XXZ chain by changing the anisotropy parameter. Long range order also typically emerges after breaking the integrability of the model.

description: In this paper we study the dynamics in the general case for a Tavis Cummings atom in a non-uniform cavity. In addition to the dynamical Stark shift, the center-of-mass motion of the atom and the recoil effect are considered in both - the weak and the strong cavity atom coupling regimes. It is shown that the spatial motion of the atom inside the cavity in the resonant case leads to a transition between topologically different solutions. This effect is manifested by a singularity in the inter-level transition spectrum. In the non-resonant case, the spatial motion of the atom leads to a switching of the spin orientation. In both effects, the key factor is the relation between the values of the Stark shift and the cavity field coupling constant. We also investigate the entanglement of an atom in the cavity with the radiation field. It is shown that the entanglement between the atom and the field, usually quantified in terms of purity, decreases with increasing the Stark shift.
