description: Modifying black hole horizon can drastically change the spectrum of quasinormal modes. But if the modification is close enough to the horizon the ringdown signal remains almost unaltered, and well described by the quasinormal modes of the original GR solution. I show how the original quasinormal modes emerge in the sum over the new modes.

description: The distribution of moving groups in the solar neighborhood has been used to constrain dynamical properties of the Milky Way for decades. The kinematic bimodality between the main mode (Hyades, Pleiades, Coma Berenices, and Sirius) and Hercules can be explained by two different bar models -- via the outer Lindblad resonance of a bar with a high pattern speed ($\sim$55 km s$^{-1}$ kpc$^{-1}$), or via the corotation resonance of a bar with a low pattern speed ($\sim$40 km s$^{-1}$ kpc$^{-1}$). Recent works directly studying the kinematics of bar stars and gas flows near the center of the Galaxy have converged on the low pattern speed model. In this paper, we independently confirm this result by using Gaia DR3 to directly study the variation of Hercules across Galactic azimuth. We find that Hercules increases in $V_ϕ$ and becomes stronger as we move towards the minor axis of the bar, and decreases in $V_ϕ$ and becomes weaker as we move towards the major axis of the bar. This is in direct agreement with theoretical predictions of a low pattern speed bar model in which Hercules is formed by the corotation resonance with stars orbiting the bar's L4/L5 Lagrange points.

description: The objective was to evaluate the anticancer and antioxidant activities of the methanolic extracts of halophilic bacteria, isolated from soil samples of Marakkanam saltern and Pichavaram mangrove forest, India. Radical Scavenging activity, reducing power, and metal ion chelation ability was used to evaluate the antioxidant potential of the metabolic extracts, whereas cell viability was determined by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay. The methanolic extract of Bacillus VITPS7 exhibited significant antioxidant property. Bacillus VITPS14 and Bacillus VITPS16 extracts were cytotoxic against HeLa cell lines but not to A549 cell lines. Colorimetric assays for the presence of specific metabolites including, total flavonoid and β carotene content were performed. The presence of these specific classes of metabolites was confirmed by UV–Visible spectrophotometry, Nuclear Magnetic Resonance (NMR) spectroscopy and Gas Chromatography–Mass Spectrometry (GC–MS). Specific NMR signals revealed the presence of aromatic and unsaturated metabolites whereas GC–MS analysis indicated the presence of metabolites such as squalene and methyl hexadeconate. The present study thus reports for the first time the presence of squalene in Bacillus VITPS12 and Planococcus maritimus VITP21, in addition to other metabolites that contribute to the observed antioxidant or/and cytotoxicity, thus revealing the therapeutic potential of these selected halophilic bacterial isolates.

description: Structural superlubricity, one of the most important concepts in modern tribology, has attracted lots of interest in both fundamental research and practical applications. However, the underlying model, known as the Prandtl-Tomlinson (PT) model, is oversimplified and not for real processes, despite its prevalence in frictional and structural lubricant studies. Here, with a realistic system, cholesteric liquid crystals, confined between two atomically smooth surfaces, we measure both the surface torque during rotational friction and the molecular rotation from the commensurate to incommensurate configuration at the onset of structural lubricity. Furthermore, by changing the surface potential or the strain, the Aubry transition is confirmed. The results agree well with the description by a quasi-one-dimensional version of the PT model and provide molecular evidence for rupture nucleation during static friction. Our study bridges the gap between theories and experiments and reinforces the connection between friction and fracture.

description: A study was performed involving a series of double-headed carboxylate collectors with varying distance between the head groups (one, two or three carbon atoms). A collector with the same alkyl chain length but with only one carboxylate group was also included. All these were amino-acid based amphiphiles and the polar head group was connected to the hydrophobic tail via an amide linkage. Selective flotation recovery of different calcium minerals using these collectors was investigated. The double-headed collector with one carbon atom between the carboxylate groups was an apatite and fluorite specific reagent while the monocarboxylate surfactant showed high specificity for calcite. The flotation behavior of a simple conventional collector of the same alkyl chain length, a fatty acid salt, was also determined under identical flotation conditions in order to understand the effect of the amide group. Complementary experiments (ζ potential measurements, adsorption isotherm determinations) were also performed for these reagents. In order to shed light on the selectivity obtained with the dicarboxylate surfactants, the distances between the head groups were calculated and compared with the distances between neighboring calcium atoms on the surface of the minerals. It was found that the high degree of selectivity could be rationalized by perfect matching of these distances. To the best of our knowledge this is the first study where flotation selectivity in complex calcium mineral systems has been explained in terms of molecular recognition governing the interaction between the collector and the mineral surface.

description: The superfield formulation of two - dimensional $N=4$ Extended Supersymmetric Quantum Mechanics (SQM) is described. It is shown that corresponding classical Lagrangian describes the motion in the conformally flat metric with additional potential term. The Bose and Fermi sectors of two- and three-dimensional $N=4$ SQM are analyzed. The structure of the quantum Hamiltonians is such, that the usual Shrödinger equation in the flat space arises after some unitary transformation, demonstrating the effect of transmutation of the coupling constant and the energy of the initial model in some special cases.

Beyond the Rozanov Bound on Electromagnetic Absorption via Periodic Temporal Modulations

description: Incorporating time-varying elements into electromagnetic systems has shown to be a powerful approach to challenge well-established performance limits, for example bounds on absorption and impedance matching. So far, the majority of these studies have concentrated on time-switched systems, where the material undergoes instantaneous modulation in time while the input field is entirely contained within it. This approach, however, necessitates accurate timing of the switching event and limits how thin the system can ultimately be due to the spatial width of the impinging pulse. To address these challenges, here we investigate the periodic temporal modulation of highly lossy materials, focusing on their relatively unexplored parametric absorption aspects. Our results reveal that, by appropriately selecting the modulation parameters, the absorption performance of a periodically modulated absorber can be greatly improved compared to its time-invariant counterpart, and can even exceed the theoretical bound for conventional electromagnetic absorbers, namely, the "Rozanov bound". Our findings thus demonstrate the potential of periodic temporal modulations to enable significant improvements in absorber performance while circumventing the limitations imposed by precise timing and material thickness in time-switched schemes, opening up new opportunities for the design and optimization of advanced electromagnetic absorber systems for various applications.

description: Archaeological digital data, like archaeological artifacts, are non-renewable resources that, once lost, are gone forever. Because digital data are so new in comparison to paper records, archaeologists lose data frighteningly often. First, this thesis summarizes my experience interning with Digital Antiquity, an organization specializing in preserving digital data. Second, this thesis details considerations in preparing, storing, and disseminating digital archaeological information. Finally, this thesis describes potential cultural, professional and educational concerns for users of digital archaeological repositories. As archaeologists create greater amounts of digital data, the digital curation crisis will grow. While a perfect solution has not yet been implemented, pioneering archaeologists have identified steps every archaeologist can follow to ensure that the fruits of their intellectual labors are not lost, while at the same time taking advantage of the unique properties of digital data to improve data and information sharing and use in archaeology. Digital data are useful in ways that data on paper are not and cannot be. Digital data allow archaeologists to collaborate on large projects, communicate more effectively, and even reconstruct entire excavations. However, digital data are also far less stable than paper records. While a paper record may last well over a thousand years if kept in the right conditions, digital data are often unreadable in less than ten years, even when traditional preservation methods are used. Digital storage is becoming the norm for archaeological publication, even though most archaeologists probably do not consider the downsides of digital publication. Moreover, many specialized archaeological data only exist in digital formats (e.g., laser scans, digital photographs, extensive databases) and archaeologists will (and have) lost these datasets because of faults in digital preservation. Digital data often represent the only record left after archaeologists excavate a site, and the loss of such valuable data is akin to bulldozing a site. This thesis details my experiences during my internship at Digital Antiquity (an organization which specializes in data archiving), provides examples of other projects working on the digital curation crisis and gray literature problems, and finally discusses the needs that these organizations may not be considering fully in their plans. This information will provide a primer for archaeologists about what and who to consider when creating, publishing, and storing data and information in digital formats.

description: Magnetic micelle nanoparticles with thermoresponsive behavior were designed for thermo-triggered paclitaxel delivery. For this purpose, thermoresponsive triblock copolymer poly(N-isopropyl acrylamide)-b-polycaprolactone-b-poly(N-isopropyl acrylamide) was prepared. The magnetic micelle was formed by self-assembly of triblock copolymer on the magnetite which was coated by oleic acid. The size of the magnetic micelle was between 30–40 nm reported by transmission electron microscopy. Also, dynamic light scattering indicated the hydrodynamic diameter was thermal dependent. Moreover, the drug release profile showed thermo-triggered release of paclitaxel. Thus, the smart nanocarrier has potential to be applied in both chemotherapy and hyperthermia treatment.

description: Earth Mounds 33 and 34 are located in the Wathayn locality on the Weipa Peninsula of northern Cape York in Queensland, Australia. Evidence suggests that occupation of the earth mounds at Wathayn began after 2000 BP, with the height of occupation occurring between 500 and 100 BP. Use of the earth mounds on the Weipa Peninsula continued well after European settlement, with evidence for Aboriginal adoption of new technologies suggestive of occupation into the modern era (Stevenson et al. 2015:28). The Wathayn traditional owners continue to use the same cooking methods as those associated with the earth mounds (Foghlú 2017:62). The appearance and gradual predominance of earth mounds on the landscape could signal new diets adopted in the mid-Holocene (Robert Jones, personal communication, 18 June 2019; Foghlú 2017:66). Therefore, pollen, phytolith, and starch analyses of sediment from Earth Mounds 33 and 34 at Wathayn were sought to investigate whether or not components of diet could be detected, and, through the resultant data, specific questions about changing environment, demographics, and subsistence could be answered.

description: The formation of a regular lattice of quantized vortices in a fluid under rotation is a smoking-gun signature of its superfluid nature. Here we study the vortex lattice in a dilute superfluid gas of bosonic atoms at zero temperature along the crossover from the weak-coupling regime, where the inter-atomic scattering length is very small compared to the average distance between atoms, to the unitarity regime, where the inter-atomic scattering length diverges. This study is based on high-performance numerical simulations of the time-dependent nonlinear Schrodinger equation for the superfluid order parameter in three spatial dimensions, using a realistic analytic expression for the bulk equation of state of the system along the crossover from weak-coupling to unitarity. This equation of state has the correct weak-coupling and unitarity limits and faithfully reproduces the results of an accurate multi-orbital microscopic calculation. Our numerical predictions of the number of vortices and root-mean-square sizes are important benchmarks for future experiments.

description: We present a new class of solutions of D=10, N=2 chiral supergravity. A nonvanishing background for the field strength G_{MNR} of the complex two-form triggers AdS_3 x M_7 compactifications, where M_7 is a 7-dimensional compact manifold. When M_7 is a nonsymmetric coset space G/H, we can always find a set of constants G_{MNR} covariantly conserved and thus satisfying the field equations. For example the structure constants of G with indices in the G/H directions are a covariantly conserved tensor. In some symmetric G/H, where these structure constants vanish, there may still exist conserved 3-forms, yielding AdS_3 x G/H solutions. The conditions for supersymmetry of the AdS_3 x M_7 compactifications are derived, and tested for the supersymmetric solutions AdS_3 x S^3 x T^4 and AdS_3 x S^3 x S^3 x S^1. Finally, we show that the AdS_3 x S^3 x T^4 supersymmetric background can be seen as the sigma = 0 limit in a one-parameter class of solutions of the form AdS_3 x S^3 x CP^2, the parameter sigma being the inverse "radius" of CP^2. For sigma different from 0 all supersymmetries are broken.

Exploring New Asymmetric Reactions Catalysed by Dicationic Pd(II) Complexes
Creators: name: Smith, Alexander
Publisher: name: Imperial College London
Year: 2010

description: Dicationic palladium(II) complexes have been shown to catalyse a number of important asymmetric transformations including Michael, Mannich and aldol reactions. This PhD thesis describes work undertaken to discover and develop novel applications of dicationic palladium(II) complexes in asymmetric catalysis. The introductory chapter outlines the advances in catalytic asymmetric α-functionlisation of β-ketoesters. This includes both metal-catalysed and organocatalytic processes with reference to C-C, C-X (X = F, Cl, Br), C-N, C-O and C-S bond forming reactions. Chapter 2 discusses the work towards the synthesis of β-amino acids via Michael reactions catalysed by Pd(II) complexes. These reactions failed to proceed with good enantioselectivities, leading to the investigation of a number of related transformations. In the following Chapter the reaction of β-ketoesters with oxaziridines to generate α- hydroxy-β-ketoesters was discovered. Extensive screening of reaction parameters led to the identification of dimethyldioxirane (DMD) as a superior oxidant for this reaction, providing ee’s of up to 98%. Examining a range of substrates revealed several key structural elements required for both reactivity and enantioselectivity. Determination of the absolute stereochemistry of the products revealed opposite facial selectivity to that reported in a number of related reactions. Chapter 4 discusses the results of DFT calculations undertaken by a colleague (Prof H. S. Rzepa), to identify the origins of stereoselectivity in the Pd(II) mediated α-hydroxylation of β-ketoesters with DMD. Chapter 5 discusses the investigation of carboxylated pyrrolidinones and succinimides as substrates in the hydroxylation reaction. Successful α-hydroxylation provided access to 3 classes of synthetically useful hydroxylated N-heterocyclic products with high optical purity, and brief synthetic studies directed towards the natural product Pramanicin were undertaken. The last Chapter contains experimental procedures and characterisation data of all the compounds synthesised during the course of this project.

Measurement of the W → ev cross section with early data from the CMS experiment at CERN
Creators: name: Rompotis, Nikolaos
Publisher: name: Imperial College London
Year: 2011

description: The Compact Muon Solenoid (CMS) is a general purpose detector designed to study proton-proton collisions, and heavy ion collisions, delivered by the Large Hadron Collider (LHC) at the European Laboratory for High Energy Physics (CERN). This thesis describes a measurement of the inclusive W → ev cross section at 7 TeV centre of mass energy with 2:88 ± 0:32 pb-1 of LHC collision data recorded by CMS between March and September 2010. W boson decays are identified by the presence of a high-pT electron that satisfies selection criteria in order to reject electron candidates due to background processes. Electron selection variables are studied with collision data and found to be in agreement with expectations from simulation. A fast iterative technique is developed to tune electron selections based on these variables. Electron efficiency is determined from simulation and it is corrected from data using an electron sample from Z decays. The number of W candidates is corrected for remaining background events using a fit to the missing transverse energy distribution. The measured value for the inclusive W production cross section times the branching ratio of the W decay in the electron channel is: σ(pp → W+X)xBR(W → ev) = 10.04±0.10(stat)±0.52(syst)±1.10(luminosity) nb; which is in excellent agreement with theoretical expectations.

description: A new superferric magnetic storage ring with highly homogeneous field at 1.45 T and weak electrostatic focussing is described which has been set up at the Brookhaven National Laboratory (BNL), USA, for a precision measurement of the magnetic anomaly of the muon. The toroidal storage volume has a radius of 7 m and a diameter of 9 cm. Precision magnetic field determination based on pulsed NMR on protons in H$_2$O yields the field to better than 0.1 ppm everywhere within the storage region. Follow on experiments using the setup have been already suggested to search for a finite mass of the muon neutrino and to search for an electric dipole moment of the muon with significantly increased accuracy. The high homogeneity of the field suggests the usage of such devices as a mass spectrometer for heavier particles as well.

description: A comprehensive congener specific assessment of polychlorinated biphenyls (PCBs) was conducted for the first time in Bangladesh. All 209 PCB congeners in the surficial coastal sediments from the coastal areas of Bangladesh were analyzed by GC-MS/MS. The total concentrations of PCBs (∑PCBs) varied from 5.27 to 92.21 and 4.61 to 105.3 ng/g dw in winter and summer, respectively, and the ranges were comparable to or higher than those recorded in the sediments from the coastal areas of India, Korea, China, and Taiwan. The seasonal difference in the levels of PCBs was not statistically significant (p > 0.05). The spatial distribution revealed that the areas with recent urbanization and industrialization (Chittagong, Cox’s Bazar and Sundarbans) were more contaminated with PCBs than the unindustrialized area (Meghna Estuary). Moderately chlorinated (4–6 Cl) homologs dominated PCB profiles. A set of congeners based on their detection frequencies and abundance were identified and categorized as potential environmental marker PCBs, which can be used for the future selective monitoring studies where there would be limitations on whole congener assessment. Ecotoxicologically, the sedimentary PCB concentrations exceeded some of the existing environmental quality standards, suggesting a potential threat to the aquatic organisms in the Bangladeshi coastal areas.

description: Generating high-fidelity time series data using generative adversarial networks (GANs) remains a challenging task, as it is difficult to capture the temporal dependence of joint probability distributions induced by time-series data. Towards this goal, a key step is the development of an effective discriminator to distinguish between time series distributions. We propose the so-called PCF-GAN, a novel GAN that incorporates the path characteristic function (PCF) as the principled representation of time series distribution into the discriminator to enhance its generative performance. On the one hand, we establish theoretical foundations of the PCF distance by proving its characteristicity, boundedness, differentiability with respect to generator parameters, and weak continuity, which ensure the stability and feasibility of training the PCF-GAN. On the other hand, we design efficient initialisation and optimisation schemes for PCFs to strengthen the discriminative power and accelerate training efficiency. To further boost the capabilities of complex time series generation, we integrate the auto-encoder structure via sequential embedding into the PCF-GAN, which provides additional reconstruction functionality. Extensive numerical experiments on various datasets demonstrate the consistently superior performance of PCF-GAN over state-of-the-art baselines, in both generation and reconstruction quality. Code is available at https://github.com/DeepIntoStreams/PCF-GAN.

Features for matching people in different views

description: There have been significant advances in the computer vision field during the last decade. During this period, many methods have been developed that have been successful in solving challenging problems including Face Detection, Object Recognition and 3D Scene Reconstruction. The solutions developed by computer vision researchers have been widely adopted and used in many real-life applications such as those faced in the medical and security industry. Among the different branches of computer vision, Object Recognition has been an area that has advanced rapidly in recent years. The successful introduction of approaches such as feature extraction and description has been an important factor in the growth of this area. In recent years, researchers have attempted to use these approaches and apply them to other problems such as Content Based Image Retrieval and Tracking. In this work, we present a novel system that finds correspondences between people seen in different images. Unlike other approaches that rely on a video stream to track the movement of people between images, here we present a feature-based approach where we locate a target’s new location in an image, based only on its visual appearance. Our proposed system comprises three steps. In the first step, a set of features is extracted from the target’s appearance. A novel algorithm is developed that allows extraction of features from a target that is particularly suitable to the modelling task. In the second step, each feature is characterised using a combined colour and texture descriptor. Inclusion of information relating to both colour and texture of a feature add to the descriptor’s distinctiveness. Finally, the target’s appearance and pose is modelled as a collection of such features and descriptors. This collection is then used as a template that allows us to search for a similar combination of features in other images that correspond to the target’s new location. We have demonstrated the effectiveness of our system in locating a target’s new position in an image, despite differences in viewpoint, scale or elapsed time between the images. The characterisation of a target as a collection of features also allows our system to robustly deal with the partial occlusion of the target.
Resonant 3--photon ionization of hydrogenic atoms by non-monochromatic laser field

description: We present ionization probability and line shape calculations for the two-step 3-photon ionization process, $1S \stackrel{2\hbar ω}{\longrightarrow}2S \stackrel{\hbar ω}{\longrightarrow}εP $, of the ground state of hydrogenic atoms in a non-monochromatic laser field with a time--dependent amplitude. Within the framework of a three--level model, the {\it AC Stark} shifts and non-zero ionization rates of all states involved were taken into account together with spatial and temporal inhomogeneities of the laser signal. In contrast with the usual perturbative technique, the time evolution of the atomic states was simulated by direct numerically solving the system of coupled time--dependent inhomogeneous differential equations, being equivalent to the appropriate non-stationary Schrödinger equation. Particular numerical results were obtained for typical parameters of the pulsed laser field that are employed in a new experiment to measure the $1S-2S$ energy separation in muonium at the Rutherford Appleton Laboratory. The shifts and asymmetries of the photoionization line shapes revealed may be of relevance for ultra-high precision experiments in hydrogen in CW laser fields.

description: Motor is the most widely used production equipment in industrial field. In order to realize the real-time state monitoring and multi-fault pre-diagnosis of three-phase motor, this paper presents a design of three-phase motor state monitoring and fault diagnosis system based on LabVIEW. The multi-dimensional vibration acceleration, rotational speed, temperature, current and voltage signals of the motor are collected with NI cDAQ acquisition equipment in real time and high speed. At the same time, the model of motor health state and fault state is established. The order analysis algorithm is used to analyze the data at an advanced level, and the diagnosis and classification of different fault types are realized. The system is equipped with multi-channel acquisition, display, analysis and storage. Combined with the current cloud transmission technology, we will back up the data to the cloud to be used by other terminals.

description: As a subcontractor to Northland Research, Inc., Archaeological Research Services, Inc. conducted a data recovery program at two historic sites which were affected by the construction of the Upper West Side Canal and Centennial Levee of the Central Arizona Project. Both sites are located in the Harquahala Valley of western Maricopa County, Arizona. Site AZ S:7:29(ASM) was the Enlarged (Dry Farm) Homestead of Hugh T. Stubblefield. It was occupied from 1930 or 1931 to mid 1933. Site AZ S:7:32(ASM) was the Enlarged (Dry Farm) Homestead of Lyman C. Mason and was occupied from 1929 to early- or mid-1930. Data recovery at the Stubblefield and Mason homesteads had several goals. The first was to document, in a systematic and intensive manner, the architecture and material culture of the sites, because both would be destroyed by the Central Arizona Project features. The second was to derive culture histories for the sites using archival, interview, and archaeological data sets. Beyond these immediate goals, data recovery focused on the collection of data relevant to four areas of research interest. Three of these dealt with the sensitivity of archaeological data to the behavioral systems which generated them. The fourth examined the relationship of ideal behavior, as structured by national homestead laws, to actual behavior, as seen in the interpretation and application of such laws at the local level.
