description: To date, surgery is the most common method to treat cancer. Complete tumour resection, however, can be challenging as it relies on the surgeon’s ability to visually discriminate healthy from diseased tissues. Additional contrast mechanisms are needed to further guide cancer identification during surgery. Small field of view (SFOV) gamma imaging has been widely introduced for image-guided cancer surgery. A novel SFOV hybrid gamma camera (HGC) has been developed, at the University of Leicester, that is capable of providing coaligned images from optical and gamma modalities simultaneously. The HGC has the potential to enhance tumour localisation intraoperatively. In this thesis, a dedicated near infrared fluorescence imaging (NIRFI) systems have been characterised for combination with the HGC. The performance of two NIRF imaging systems using phantom studies, various fluorophores and different experimental configurations was evaluated. Bespoke lymph node phantoms simulating metastases and tissue-like layers were constructed to evaluate the detection capability. The threshold detectable concentration of both dyes were investigated for both systems. The maximum depth at which NIRF targets could be distinguished was determined for both systems. Silicon photomultiplier (SiPM) is a novel photon sensing device, with potential applications in medical gamma imaging. This thesis also characterised different parameters of the SiPM under different operating conditions. Better knowledge of the SiPM technology was obtained to exploit its advantages in an introperative SFOV gamma imaging system. This work also reported the performance of gamma detectors comprising SiPM detector optically coupled to a monolithic GAGG:Ce and a columnar CsI:TI scintillators. A thin layer of both scintillators was investigated in order to determine their performance features such as linearity, intrinsic energy resolution and detection efficiency when combined to a SiPM.

description: A theoretical study of delayed feedback in a spin-torque nano-oscillator model is presented. The feedback acts as a modulation of the supercriticality, which results in changes in the oscillator frequency through a strong nonlinearity, amplitude modulations, and a rich modulation sideband structure in the power spectrum at long delays. Modulation sidebands persist at finite temperatures but some of the complex structure is lost through the finite coherence time of the oscillations.

description: A Euro-Asian network of four gravitational-wave (GW) interferometers is considered, taking into account the plan to create such a detector in Novosibirsk. The efficiency of the network is assessed by typical numerical criteria, which also depend on the characteristics of the received signal. In this work, we calculate the optimal orientation of the Novosibirsk detector for the problem of detecting GW radiation accompanying the collapse of the progenitor star with an initial angular momentum. The specificity of the scenario is the presence of the so-called. bar stage deformation, for which the shape of the emitted GW signal is known.

description: We study by Quantum Monte Carlo simulations the local superfluid response of small (up to 27 molecules) parahydrogen clusters, down to temperatures as low as 0.05 K. We show that at low temperature superfluidity is not confined at the surface of the clusters, as recently claimed by Khairallah et al. [Phys. Rev. Lett. 98, 183401 (2007)]. Rather, even clusters with a pronounced shell structure are essentially uniformly superfluid. Superfluidity occurs as a result of long exchange cycles involving all molecules.

Unravelling Lorentz Covariance and the Spacetime Formalism

subject: FOS: Physical sciences

description: We report the discovery of an exact mapping from Galilean time and space coordinates to Minkowski spacetime coordinates, showing that Lorentz covariance and the spacetime construct are consistent with the existence of a dynamical 3-space, and "absolute motion". We illustrate this mapping first with the standard theory of sound, as vibrations of a medium, which itself may be undergoing fluid motion, and which is covariant under Galilean coordinate transformations. By introducing a different non-physical class of space and time coordinates it may be cast into a form that is covariant under "Lorentz transformations" wherein the speed of sound is now the "invariant speed". If this latter formalism were taken as fundamental and complete we would be lead to the introduction of a pseudo-Riemannian "spacetime" description of sound, with a metric characterised by an "invariant speed of sound". This analysis is an allegory for the development of 20th century physics, but where the Lorentz covariant Maxwell equations were constructed first, and the Galilean form was later constructed by Hertz, but ignored. It is shown that the Lorentz covariance of the Maxwell equations only occurs because of the use of non-physical space and time coordinates. The use of this class of coordinates has confounded 20th century physics, and resulted in the existence of a "flowing" dynamical 3-space being overlooked. The discovery of the dynamics of this 3-space has lead to the derivation of an extended gravity theory as a quantum effect, and confirmed by numerous experiments and observations.

description: High resolution molecular line observations of CS, HCO+, C18O and N2H+ were obtained toward the starless globule FeSt 1-457 in order to investigate its kinematics and chemistry. The HCO+ and CS spectra show clear self-reversed and asymmetric profiles across the face of the globule. The sense of the observed asymmetry is indicative of the global presence of expansion motions in the outer layers of the globule. These motions appear to be subsonic and significantly below the escape velocity of the globule. Comparison of our observations with near-infrared extinction data indicate that the globule is gravitationally bound. Taken together these considerations lead us to suggest that the observed expansion has its origin in an oscillatory motion of the outer layers of the globule which itself is likely in a quasi-stable state near hydrostatic equilibrium. Analysis of the observed linewidths of CO and N2H+ confirm that thermal pressure is the dominant component of the cloud's internal support. A simple calculation suggests that the dominant mode of pulsation would be an l = 2 mode with a period of 0.3 Myr. Deformation of the globule due to the large amplitude l = 2 oscillation may be responsible for the double-peaked structure of the core detected in high resolution extinction maps. Detailed comparison of the molecular-line observations and extinction data provides evidence for significant depletion of C18O and perhaps HCO+ while N2H+ may be undepleted to a cloud depth of about 40 magnitudes of visual extinction.

Tanizaki Junʼichirō and the art of storytelling
Creators: name: Pham, Thien Truong
Publisher: name: University of British Columbia
Year: 2010

description: This thesis deals with the storytelling art of Tanizaki Jun'ichirō. An esthete par excellence, this prolific writer produced for over half a century a string of works that are essentially dedicated to the glorification of art and beauty. This glorification in turn enhances the quality of life which, also in the author's view, is both a dream and a game. Art and beauty, dreams and games are virtually the building blocks of Tanizaki's fictional universe in which illusion and reality are meant to be complementary rather than opposing forces that govern human existence. Transplanting this fabulous world into the reader's heart is the result of Tanizaki's special skill in storytelling. An analysis of his four major works will hopefully bring this skill into full view. Chapter One examines Tanizaki's early short story "Shisei" that marks his brilliant debut. Though marred by technical flaws, "Shisei" succeeds remarkably in luring the reader into a fairy-tale atmosphere where art and beauty are the only raison d'être. A sensuous style characterizes this lively tale and between the lines flows a life force that will become Tanizaki's trademark. The theme of art and beauty is brought to a climax in "Shunkinshō" which is analysed in Chapter Two. The simple perspective of "Shisei" is now abandoned, giving way to a maze of multiple viewpoints that are there for the single purpose of hypnotizing the reader. The ultimate goal is to make the reader share the passion and devotion of an artist in the pursuit of the Ideal. The monogatari style is a feature of this novella and helps generate the ambiguity needed for the narrative. Chapter Three deals with "Yume no ukihashi," a tale of dream and sensuality. Man's ambition to create and perpetuate dreams is given full treatment in this story in which illusions are the name of the game. Incest is also a thorny issue but Tanizaki seems to consciously skirt the problem with various devices. Fùten rōjin nikki, Tanizaki's crowning novel, is the subject of Chapter Four. Everything that the author stands for in his writing is now brought into focus. Using the casual form of a diary, art motifs and erotic scenes are placed at well-calculated points so that structural balance is maintained throughout the story. A game-playing spirit and the overwhelming life force which starts with "Shisei" embody this last tour-de-force that proudly consolidates the author's fame. This thesis, through the four works that are examined, can be considered an attempt to shed some light on the question of why and how Tanizaki fascinates the reader.

description: We present X-ray observations of the Hyperluminous Infrared Galaxy (HLIRG) IRAS 00182--7112 (F00183--7111) obtained using the XMM-Newton EPIC camera. A luminous hard X-ray source co-incident with the nucleus is revealed, along with weaker soft X-ray emission which may be extended or offset from the hard. The EPIC spectrum is extremely flat and shows Fe K$α$ emission with very high equivalent width: both are typical characteristics of a buried, Compton--thick AGN which is seen only in scattered light. Perhaps the most remarkable characteristic of the spectrum is that the Fe K$α$ line energy is that of He-like iron, making IRAS 00182--7112 the first hidden AGN known to be dominated by ionized, Compton thick reflection. Taking an appropriate bolometric correction we find that this AGN could easily dominate the FIR energetics. The nuclear reflection spectrum is seen through a relatively cold absorber with column density consistent with recent Spitzer observations. The soft X-ray emission, which may be thermal in nature and associated with star-forming activity, is seen unabsorbed. The soft X-rays and weak PAH features both give estimates of the star formation rate $\sim 300 M_{\odot}$ yr$^{-1}$, insufficient to power the FIR emission and supportive of the idea that this HLIRG is AGN-dominated.

description: We introduce plaquette projected entangled-pair states, a class of states in a lattice that can be generated by applying sequential unitaries acting on plaquettes of overlapping regions. They satisfy area-law entanglement, possess long-range correlations, and naturally generalize other relevant classes of tensor network states. We identify a subclass that can be more efficiently prepared in a radial fashion and that contains the family of isometric tensor network states [M. P. Zaletel and F. Pollmann, Phys. Rev. Lett. 124, 037201 (2020)]. We also show how this subclass can be efficiently prepared using an array of photon sources.

description: The Peierls-Yoccoz projection method is used to study the motion of a relativistic system of nucleons interacting with sigma and omega mesons. The nuclear system is described in a mean-field Hartree approach, including explicitly the meson contribution and the formalism is applied to some selected N=Z spherical nuclei. The center-of-mass motion correction makes the system too much bounded, but we show that an appropriate refitting of the model brings the radii and binding energies close to the experimental values.

Science, Technology and Road Safety in the Motor Age

Subjects: Uncategorized

description: The 1960s marked a moment of transformation in how the problem of mass motorization was handled by British governments, which increasingly came to realise that widespread car ownership came with costs, notably in terms of road safety. In response, the government funded research into reducing traffic collisions and minimising their injurious effects. This thesis examines British research into the road safety problem by taking an object-focused approach to analysis, foregrounding road safety objects researched during the decade. The case is made for reading objects as historical sources, with the argument that using objects contributes valuable information not available in the more traditional printed documentary archival evidence. Five key areas of British road safety research, primarily carried out by the Road Research Laboratory, form the main thesis chapters. These focus on vehicle automation, skidding, vehicle occupant restraints, visibility on the roads, and legal limits on alcohol and speed. Examples of items created, modified or researched by the Laboratory inform each chapter, supported by a wide review and analysis of contemporary printed sources. The thesis reveals the ways in which road safety was problematized in Britain during the 1960s and the research explored in the chapters is shown to represent four different approaches to reducing the road safety problem. These were accident limitation through vehicle design; safety of vehicle occupants and riders; enforcement of road safety legislation; and safety of other road users. Further categorisation of these approaches to road safety narrows research into two main areas, namely passive and active safety designs, in 1960s Britain.

description: We present a toy model where spacetime is emergent from a more fundamental microscopic system, and investigate the gray area interpolating between the collective and free-particle regimes. For a period of rapid exponential growth in the analogue universe, we argue that the intermediate regime is best described by a coloured potpourri of geometries -- a "rainbow geometry". This can be viewed as an alternative approach towards understanding quantum field theories in the presence of Lorentz-symmetry breaking at ultraviolet scales. Firstly, it is pointed out that cosmological particle production in our emergent FRW-type analogue universe, when compared to conventional semi-classical quantum gravity, is only temporarily robust against model-specific deviations from Lorentz invariance. Secondly, it is possible to carry out a straightforward quantitative analysis to estimate a suitable parameter regime for experimental (analogue) cosmology.

description: We study termination of higher-order probabilistic functional programs with recursion, stochastic conditioning and sampling from continuous distributions. Reasoning about the termination probability of programs with continuous distributions is hard, because the enumeration of terminating executions cannot provide any non-trivial bounds. We present a new operational semantics based on traces of intervals, which is sound and complete with respect to the standard sampling-based semantics, in which (countable) enumeration can provide arbitrarily tight lower bounds. Consequently we obtain the first proof that deciding almost-sure termination (AST) for programs with continuous distributions is $Π^0_2$-complete. We also provide a compositional representation of our semantics in terms of an intersection type system. In the second part, we present a method of proving AST for non-affine programs, i.e., recursive programs that can, during the evaluation of the recursive body, make multiple recursive calls (of a first-order function) from distinct call sites. Unlike in a deterministic language, the number of recursion call sites has direct consequences on the termination probability. Our framework supports a proof system that can verify AST for programs that are well beyond the scope of existing methods. We have constructed prototype implementations of our method of computing lower bounds of termination probability, and AST verification.

description: High-throughput material screening for the discovery and design of novel functional materials requires automatized analyses of theoretical and experimental data. Here we study the subject of human-free analyses of one-dimensional spectroscopic data, {\it e.g.} in the frequency domain, via employing deep convolution neural network. Specifically, we trained various deep convolution neural network and benchmarked their performance in decomposing one-dimensional noisy data into multiple nonorthogonal peaks in an iterative manner, after which a conventional basin-hopping algorithm was applied to further reduce residual fitting error. Among six different network architectures, a variant of "Squeeze-and-excitation" network (SENet) structure that we first propose in this study shows the best performance. Dependency of training performance with respect to the choice of the loss function is also discussed. We conclude by applying our modified SENet model to experimental photoemission spectra of graphene, MoS$_2$, and WS$_2$ and address its potential applications and limitations.

description: We report on photoluminescence in the 3-7 $μ$m mid-wave infrared (MWIR) range from sub-100 nm strained thin films of rocksalt PbSe(001) grown on GaAs(001) substrates by molecular beam epitaxy. These bare films, grown epitaxially at temperatures below 400 °C, luminesce brightly at room temperature and have minority carrier lifetimes as long as 172 ns. The relatively long lifetimes in PbSe thin films are achievable despite threading dislocation densities exceeding $10^9$ $cm^{-2}$ arising from island growth on the nearly 8% lattice- and crystal-structure-mismatched GaAs substrate. Using quasi-continuous-wave and time-resolved photoluminescence, we show Shockley-Read-Hall recombination is slow in our high dislocation density PbSe films at room temperature, a hallmark of defect tolerance. Power-dependent photoluminescence and high injection excess carrier lifetimes at room temperature suggest that degenerate Auger recombination limits the efficiency of our films, though the Auger recombination rates are significantly lower than equivalent, III-V bulk materials and even a bit slower than expectations for bulk PbSe. Consequently, the combined effects of defect tolerance and low Auger recombination rates yield an estimated peak internal quantum efficiency of roughly 30% at room temperature, unparalleled in the MWIR for a severely lattice-mismatched thin film. We anticipate substantial opportunities for improving performance by optimizing crystal growth as well as understanding Auger processes in thin films. These results highlight the unique opportunity to harness the unusual chemical bonding in PbSe and related IV-VI semiconductors for heterogeneously integrated mid-infrared light sources constrained by tight thermal budgets in new device designs.

description: Within the framework of the dinuclear system model, the production of superheavy element Z=117 in possible projectile-target combinations is analyzed systematically. The calculated results show that the production cross sections are strongly dependent on the reaction systems. Optimal combinations, corresponding excitation energies and evaporation channels are proposed in this letter, such as the isotopes ^{248,249}Bk in ^{48}Ca induced reactions in 3n evaporation channels and the reactions ^{45}Sc+^{246,248}Cm in 3n and 4n channels, and the system ^{51}V+^{244}Pu in 3n channel.

Angular deviations: From a cubic equation to a universal closed formula to determine the peak position of reflected and (upper) transmitted beams

description: Angular deviations and lateral displacements are optical effects widely investigated in literature. In this paper, by using the Taylor expansion of the Fresnel coefficients, we obtain an analytic expression for the beam reflected by and (upper) transmitted through a dielectric prism. These analytical approximations lead to a cubic equation which allows to determine the angular deviations of the optical beams. Near the Brewster angles, under specific conditions, we obtain a universal formulation for the cubic equation. Its explicit solution determines the peak position of the reflected and (upper) transmitted beams. The universal solution could be of great utility in future experimental implementations. The analytic results show an excellent agreement with the numerical calculation and the analytic expressions given for the reflected and (upper) transmitted beams should play an important role in the weak measurements analysis.

description: In helioseismology, there is a well-known offset between observed and computed oscillation frequencies. This offset is known to arise from improper modeling of the near-surface layers of the Sun, and a similar effect must occur for models of other stars. Such an effect impedes progress in asteroseismology, which involves comparing observed oscillation frequencies with those calculated from theoretical models. Here, we use data for the Sun to derive an empirical correction for the near-surface offset, which we then apply three other stars (alpha Cen A, alpha Cen B and beta Hyi). The method appears to give good results, in particular providing an accurate estimate of the mean density of each star.

description: Probing the geometry of the universe is one of the most important endevours in cosmology. Current observational data from the Cosmic Microwave Background anisotropy (CMB), galaxy surveys and type Ia supernovae (SNe Ia) strongly constrain the curvature of the universe to be close to zero for a universe dominated by a cosmological constant or dark energy with a constant equation of state. Here we investigate the role of cosmic priors on deriving these tight bounds on geometry, by considering a landscape motivated scenario with an oscillating curvature term. We perform a likelihood analysis of current data under such a model of non-trivial geometry and find that the uncertainties on curvature, and correspondingly on parameters of the matter and dark energy sectors, are larger. Future dark energy experiments together with CMB data from experiments like Planck could dramatically improve our ability to constrain cosmic curvature under such models enabling us to probe possible imprints of quantum gravity.

description: In contrast to electron (fermion) systems, topological phases of charge neutral bosons have been poorly understood despite recent extensive research on insulating magnets. The most important unresolved issue is how the inevitable inter-bosonic interactions influence the topological properties. It has been proposed that the quantum magnet SrCu$_2$(BO$_3$)$_2$ with an exact ground state serves as an ideal platform for this investigation, as the system is expected to be a magnetic analogue of a Chern insulator with electrons replaced by bosonic magnetic excitations (triplons). Here, in order to examine topologically protected triplon chiral edge modes in SrCu$_2$(BO$_3$)$_2$, we measured and calculated the thermal Hall conductivity $κ_{xy}$. Our calculations show that the sign of $κ_{xy}$ is negative, which is opposite to the previous calculations, and its magnitude is 2$π$ times smaller. No discernible $κ_{xy}$ was observed, which is at most 20-30% of our calculations if present. This implies that even relatively weak inter-particle interactions seriously influence the topological transport properties at finite temperatures. These demonstrate that, in contrast to fermionic cases, the picture of non-interacting topological quasi-particles cannot be naively applied to bosonic systems, calling special attention to the interpretation of the topological bosonic excitations reported for various insulating magnets.

description: Chrysopodes (Neosuarius) – flavescens species-group Six Chrysopodes (Neosuarius) species from the western regions of South America form a natural group (the flavescens group); this group includes Chrysopodes (N.) escomeli , C. (N.) flavescens , C. (N.) porterinus , and three species endemic to Galápagos Islands [C. (N.) nigricubitus , C. (N.) nigripilosus , C. (N.) pecki]. The following characteristics distinguish them from the collaris -group: 1 Body (dorsal): primary color cream or tan, with brown or brownish markings 2 Head: cream-colored to tan, with brown markings; frons with pair of brown spots below toruli 3 Male: abdomen with terminal segments (S8+9, sometimes T9+ectoproct) having sclerotized transverse bands and invaginated re-enforcements 4 Male: tip of S8+9 with delicate, eversible membrane lacking robust gonocristae; membrane sometimes modified into paired eversible pouches (Galápagos species) 5 Female: spermatheca tubular, opening to the bursa copulatrix via an elongate dorsal slit 6 Female: spermathecal duct relatively short (or weakly sclerotized) 7 Female: Bursal duct apparently modified into a fluted, tightly folded structure below the bursa. [The origin of the fluted area below the bursa is not completely clear. I consider it to be an enlarged part of the bursal duct and treat it as such in the descriptions and on the figures. However, it could be part of the bursa copulatrix, in which case the bursal duct would be greatly reduced.] 8 Female: bursal glands sometimes with elongate, slender accessory ducts

description: From several neutrino oscillation experiments, we understand now that neutrinos have mass. However, we really don't know what mechanism is responsible for producing this neutrino mass. Current or planned neutrino experiments utilize neutrino beams and long-baseline detectors to explore flavor mixing but do not address the question of the origin of neutrino mass. In order to answer that question, neutrino interactions need to be explored at much higher energies. This paper outlines a program to explore neutrinos and their interactions with various particles through a series of experiments involving colliding neutrino beams.

description: The carrier transport and the motion of a vortex system in a mixed state of an electron-doped high-temperature superconductors Nd2-xCexCuO4 were investigated. To study the anisotropy of galvanomagnetic effects of highly layered NdCeCuO system we have synthesized Nd2-xCexCuO4/SrTiO3 epitaxial films with non-standart orientations of the c-axis and conductive CuO2 layers relative to the substrate. The variation ofe the angle of inclination of the magnetic field B, relative to the current J, reveals that the behavior of both the in-plane r_xx(B) and the out-plane r_xy(B) resistivities in the mixed state is mainly determined by the perpendicular to J component of B, that indicates the crucial role of the Lorentz force F_L~[JxB] and defines the motion of Josephson vortices across the CuO2 layers.

Measuring primordial non-gaussianity without cosmic variance

Year: 2008

description: Non-gaussianity in the initial conditions of the universe is one of the most powerful mechanisms to discriminate among the competing theories of the early universe. Measurements using bispectrum of cosmic microwave background anisotropies are limited by the cosmic variance, i.e. available number of modes. Recent work has emphasized the possibility to probe non-gaussianity of local type using the scale dependence of large scale bias from highly biased tracers of large scale structure. However, this power spectrum method is also limited by cosmic variance, finite number of structures on the largest scales, and by the partial degeneracy with other cosmological parameters that can mimic the same effect. Here we propose an alternative method that solves both of these problems. It is based on the idea that on large scales halos are biased, but not stochastic, tracers of dark matter: by correlating a highly biased tracer of large scale structure against an unbiased tracer one eliminates the cosmic variance error, which can lead to a high signal to noise even from the structures comparable to the size of the survey. The square of error improvement on non-gaussianity parameter f_nl relative to the power spectrum method scales as Pn/2, where P and n is the power spectrum and the number density of the biased tracer, respectively. For an ideal survey out to z=2 the error reduction can be as large as a factor of seven, which should guarantee a detection of non-gaussianity from an all sky survey of this type. The improvements could be even larger if high density tracers that are sensitive to non-gaussianity can be identified and measured over a large volume.

description: Cross-lingual text representations have gained popularity lately and act as the backbone of many tasks such as unsupervised machine translation and cross-lingual information retrieval, to name a few. However, evaluation of such representations is difficult in the domains beyond standard benchmarks due to the necessity of obtaining domain-specific parallel language data across different pairs of languages. In this paper, we propose an automatic metric for evaluating the quality of cross-lingual textual representations using images as a proxy in a paired image-text evaluation dataset. Experimentally, Backretrieval is shown to highly correlate with ground truth metrics on annotated datasets, and our analysis shows statistically significant improvements over baselines. Our experiments conclude with a case study on a recipe dataset without parallel cross-lingual data. We illustrate how to judge cross-lingual embedding quality with Backretrieval, and validate the outcome with a small human study.
