description: The nonlinear oscillator model allows a basic understanding of all nonlinear processes and can be adopted to analyse optical vibrational modes and electronic transition in molecules and crystals, in order to derive general properties of harmonic generation to all orders. In particular, we obtain Kramers Kroenig relations and sum rules referred to all momenta of the susceptibility, and Miller's empirical rules to all orders. Since the above properties only depend on time causality and not on the specific microscopic model, they can be adopted for the quantum mechanical description, sustituting in the classical expression the derivatives of the potential with their expectation values.

description: Broad-line Ic supernovae (SNe Ic-BL) are a very rare class of core-collapse supernovae exhibiting high ejecta velocities and high kinetic energies. They are the only type of SNe that accompany long gamma-ray burst (GRB) explosions. Systematic differences found in the spectra of SNe Ic-BL with and without GRBs (GRB-SNe and SNe Ic-BL, respectively) suggest that either the progenitor or/and explosion mechanism of SNe Ic-BL with and without a GRB differ, or the difference could be only due to the viewing angle of the observer with respect to the orientation of the collimated explosion. We present the systematic comparison of the host galaxies of broad-lined SNe Ic with and without a detected GRB, the latter being detected in untargeted surveys, with the aim to find out whether there are any systematic differences between the environments in which these two classes of SNe preferentially explode. We study photometric properties of the host galaxies of a sample of 8 GRB-SNe and a sample of 28 SNe Ic-BL at z < 0.2. The two galaxy samples have indistinguishable luminosity and proper size distribution. We find indications that GRB-SNe on average occur closer to the centres of their host galaxies, i.e. the samples have a different distribution of projected offsets, normalized by the galaxy sizes. In addition we compare gas-phase metallicities of the GRB-SNe and SNe Ic-BL host samples and find that a larger fraction of super-solar metallicity hosts are found among the SNe Ic-BL without a GRB. Our results are indicative of a genuine difference between the two types of explosions and suggest that the viewing angle is not the main source of difference in the spectra of the two classes. We discuss the implications our results have on our understanding of progenitors of SNe Ic-BL with and without a GRB.

description: Non-Gaussian nature of the probability distribution of particles' displacements in the supercooled temperature regime in glass-forming liquids are believed to be one of the major hallmarks of glass transition. It is already been established that this probability distribution which is also known as the van Hove function show universal exponential tail. The origin of such an exponential tail in the distribution function is attributed to the hopping motion of particles observed in the supercooled regime. The non-Gaussian nature can also be explained if one assumes that the system has heterogeneous dynamics in space and time. Thus exponential tail is the manifestation of dynamic heterogeneity. In this work we directly show that non-Gaussanity of the distribution of particles' displacements occur over the dynamic heterogeneity length scale and dynamical behaviour course grained over this length scale becomes homogeneous. We study the non-Gaussianity of van Hove function by systematically coarse graining at different length scale and extract the length scale of dynamic heterogeneity at which the shape of the van Hove function crosses over from non-Gaussian to Gaussian. The obtained dynamic heterogeneity scale is found to be in very good agreement with the scale obtained from other conventional methods.

Archaeological Overview
Systematic Survey

description: In January of 1981, Northland Research, Inc. (Northland) conducted an archaeological survey of five seismic lines located by Petroleum Geophysical Company on the northern slope of the Spring Mountains in Clark County, Nevada. The report of the results of that survey is dated 3 February 1981. This report contains the results of the survey of two additional seismic lines located within the same seismic program, and is a supplement to the original report. This survey, which totalled 9.35 miles (14.96 km) in length, was conducted on 25, 26 and 27 June 1981. No cultural resources were recorded. In consultation with the Bureau of Land Management, Las Vegas District archaeologist, it was determined that the proposed seismic testing activity would have no adverse impact on cultural resources. As a result, Petroleum Geophysical received verbal approval to proceed with their field tests.

description: In this paper we propose two numerical algorithms to solve a coupled PDE-ODE system which models a slow vehicle (bottleneck) moving on a road together with other cars. The resulting system is fully coupled because the dynamics of the slow vehicle depends on the density of cars and, at the same time, it causes a capacity drop in the road, thus limiting the car flux. The first algorithm, based on the Wave Front Tracking method, is suitable for theoretical investigations and convergence results. The second one, based on the Godunov scheme, is used for numerical simulations. The case of multiple bottlenecks is also investigated.

description: We investigate the universality of microscopic eigenvalue correlations for Random Matrix Theories with the global symmetries of the QCD partition function. In this article we analyze the case of real valued chiral Random Matrix Theories ($β=1$) by relating the kernel of the correlations functions for $β=1$ to the kernel of chiral Random Matrix Theories with complex matrix elements ($β= 2$), which is already known to be universal. Our proof is based on a novel asymptotic property of the skew-orthogonal polynomials: an integral over the corresponding wavefunctions oscillates about half its asymptotic value in the region of the bulk of the zeros. This result solves the puzzle that microscopic universality persists in spite of contributions to the microscopic correlators from the region near the largest zero of the skew-orthogonal polynomials. Our analytical results are illustrated by the numerical construction of the skew-orthogonal polynomials for an $x^4$ probability potential.

description: We present dyonic multi-membrane solutions of the N=2 D=8 supergravity theory that serves as the effective field theory of the $T^2$-compactified type II superstring theory. The `electric' charge is fractional for generic asymptotic values of an axion field, as for D=4 dyons. These membrane solutions are supersymmetric, saturate a Bogomolnyi bound, fill out orbits of an $Sl(2;\Z)$ subgroup of the type II D=8 T-duality group, and are non-singular when considered as solutions of $T^3$-compactified D=11 supergravity. On $K_3$ compactification to D=4, the conjectured type II/heterotic equivalence allows the $Sl(2;\Z)$ group to be reinterpreted as the S-duality group of the toroidally compactified heterotic string and the dyonic membranes wrapped around homology two-cycles of $K_3$ as S-duals of perturbative heterotic string states.

description: This project has been conducted in light of extensive research that is warning of rapidly increasing housing problems facing older people. The three main factors are: an ageing population, reducing rates of home ownership and significant increases in older people relying on rental accommodation to age-in-place in their later years. The objective of the Project is to increase awareness of older people’s housing issues across Australia, improve older people’s access to affordable housing and ensure better availability of services that can help older people in housing difficulty. More specifically the aims of this project for New South Wales are to: Identify what is the level of homelessness amongst the older population in NSW and who is at risk of homelessness in NSW; examine the current state policy frameworks that impact on the housing circumstances of older people in NSW; identify what are the housing options that currently exist, what are their main characteristics and how do older people apply for them; identify what services are available to help older people access affordable and appropriate housing in NSW; propose appropriate recommendations that will lead to a systems reform approach to improve assistance and housing for low income older people.

description: Piroxicam-CMSC solid dispersions were produced by spray drying from aqueous solvents. Depending on the drug-polymer ratio, loading and entrapment efficiency of CMSC microparticles were 6.8–46.75 and 40.79–60.35% w/w, respectively. Scanning electron microscopy revealed non-spherical geometry and agglomeration of the spray-dried particles. The average size of the particles ranged from 7 to 170 µm. Infrared spectroscopy, differential scanning calorimetry, and X-ray diffraction confirmed intact crystalline piroxicam in the microparticles. In gastric pH, microparticles and native piroxicam have shown less than 25% and more than 45% of drug dissolution, respectively in 2 h. In contrast, at pH 7.4, microparticles have shown 80% of drug dissolution; whereas native piroxicam achieved only 30% of dissolution by 30 min. The spray-dried CMSC particles are efficient in restricting drug release in gastric pH and enhance drug dissolution in intestinal pH. The method is eco-friendly as it uses aqueous solvents and non-toxic materials.

description: We present results from the Wendelstein Weak Lensing (WWL) pathfinder project, in which we have observed three intermediate redshift Planck clusters of galaxies with the new 30'$\times 30$' wide field imager at the 2m Fraunhofer Telescope at Wendelstein Observatory. We investigate the presence of biases in our shear catalogues and estimate their impact on our weak lensing mass estimates. The overall calibration uncertainty depends on the cluster redshift and is below 8.1-15 per cent for $z \approx 0.27-0.77$. It will decrease with improvements on the background sample selection and the multiplicative shear bias calibration. We present the first weak lensing mass estimates for PSZ1 G109.88+27.94 and PSZ1 G139.61+24.20, two SZ-selected cluster candidates. Based on Wendelstein colors and SDSS photometry, we find that the redshift of PSZ1 G109.88+27.94 has to be corrected to $z \approx 0.77$. We investigate the influence of line-of-sight structures on the weak lensing mass estimates and find upper limits for two groups in each of the fields of PSZ1 G109.88+27.94 and PSZ1 G186.98+38.66. We compare our results to SZ and dynamical mass estimates from the literature, and in the case of PSZ1 G186.98+38.66 to previous weak lensing mass estimates. We conclude that our pathfinder project demonstrates that weak lensing cluster masses can be accurately measured with the 2m Fraunhofer Telescope.

description: We present a procedure for the design and construction of a passive, multipole, mechanical high-stop vibration isolator. The isolator, consisting of a stack of metal disks connected by thin wires, attenuates frequencies in the kilohertz range, and is suited to both vacuum and cryogenic environments. We derive an approximate analytical model and compare its predictions for the frequencies of the normal modes to those of a finite element analysis. The analytical model is exact for the modes involving only motion along and rotation about the longitudinal axis, and it gives a good approximate description of the transverse modes. These results show that the high-frequency behavior of a multi-stage isolator is well characterized by the natural frequencies of a single stage. From the single-stage frequency formulae, we derive relationships among the various geometrical parameters of the isolator to guarantee equal attenuation in all degrees of freedom. We then derive expressions for the attenuation attainable with a given isolator length, and find that the most important limiting factor is the elastic limit of the spring wire material. For our application, which requires attenuations of 250 dB at 1 kHz, our model specifies a six-stage design using brass disks of approximately 2 cm in both radius and thickness, connected by 3 cm steel wires of diameters ranging from 25 to 75 microns. We describe the construction of this isolator in detail, and compare measurements of the natural frequencies of a single stage with calculations from the analytical model and the finite element package. For translations along and rotations about the longitudinal axes, all three results are in agreement to within 10% accuracy.

Appearance Modelling and Reconstruction for Navigation in Minimally Invasive Surgery
Creators: name: Totz, Johannes
Publisher: name: Imperial College London
Year: 2012

description: Minimally invasive surgery is playing an increasingly important role for patient care. Whilst its direct patient benefit in terms of reduced trauma, improved recovery and shortened hospitalisation has been well established, there is a sustained need for improved training of the existing procedures and the development of new smart instruments to tackle the issue of visualisation, ergonomic control, haptic and tactile feedback. For endoscopic intervention, the small field of view in the presence of a complex anatomy can easily introduce disorientation to the operator as the tortuous access pathway is not always easy to predict and control with standard endoscopes. Effective training through simulation devices, based on either virtual reality or mixed-reality simulators, can help to improve the spatial awareness, consistency and safety of these procedures. This thesis examines the use of endoscopic videos for both simulation and navigation purposes. More specifically, it addresses the challenging problem of how to build high-fidelity subject-specific simulation environments for improved training and skills assessment. Issues related to mesh parameterisation and texture blending are investigated. With the maturity of computer vision in terms of both 3D shape reconstruction and localisation and mapping, vision-based techniques have enjoyed significant interest in recent years for surgical navigation. The thesis also tackles the problem of how to use vision-based techniques for providing a detailed 3D map and dynamically expanded field of view to improve spatial awareness and avoid operator disorientation. The key advantage of this approach is that it does not require additional hardware, and thus introduces minimal interference to the existing surgical workflow. The derived 3D map can be effectively integrated with pre-operative data, allowing both global and local 3D navigation by taking into account tissue structural and appearance changes. Both simulation and laboratory-based experiments are conducted throughout this research to assess the practical value of the method proposed.

description: This survey was requested to identify any cultural resources that may exist in the proposed placement area. and to evaluate the potential for adverse effects to those cultural resources resulting from the developmental activities. The area had not been previously surveyed for cultural materials. so the area was subject to a cultural resource reconnaissance. For the most part, the proposed communications line follows along existing roadways in undisturbed areas. One site was located during the survey. The site is not eligible for nomination to the National Register, therefore no further cultural resource investigations are necessary before the proposed activity may proceed as planned.

The transformation maps "waves" on a riemannian symmetric space to "waves" on its dual riemannian symmetric space. This transformation preserves the energy momentum tensor though it is not a canonical transformation. The preservation of the energy momentum tensor has a natural geometrical interpretation. The transformation maps "particle-like solutions" into static "soliton-like solutions". The results presented here generalize earlier results of E. Ivanov.

description: Parallel Talk presented at the XX International Workshop on Neutrino Telescopes - Venice 23-27 October 2023

 

Abstract:

The ENUBET project aims to design and experimentally demonstrate the concept of a monitored neutrino beam. These novel beams utilise an instrumented decay tunnel, whose detectors directly constrain the neutrino flux by reconstructing large-angle leptons from hadron decay; such a facility is an ideal tool for high-precision cross-section measurements as they provide superior control of the beam systematics than current facilities. This presentation covers the full design of a neutrino beam capable ofmonitoring produced leptons at a single particle level, constraining the final neutrino cross-section measurement to a 1% precision. This includes the design and simulation of the neutrino beamline with a new ‘static’ focussing system without magnetic horns, a 40 m decay tunnel instrumented with cost-effective particle detectors, and a 20 m transfer line for charge and momentum selection. The implementation of such a beamline at CERN is also discussed, along with the first tests of a demonstrator at CERN in 2022/23.

Threshold Corrections and Gauge Symmetry in Twisted Superstring Models

description: Threshold corrections to the running of gauge couplings are calculated for superstring models with free complex world sheet fermions. For two N=1 $SU(2)\times U(1)^5$ models, the threshold corrections lead to a small increase in the unification scale. Examples are given to illustrate how a given particle spectrum can be described by models with different boundary conditions on the internal fermions. We also discuss how complex twisted fermions can enhance the symmetry group of an N=4 $SU(3)\times U(1)\times U(1)$ model to the gauge group $SU(3)\times SU(2)\times U(1)$. It is then shown how a mixing angle analogous to the Weinberg angle depends on the boundary conditions of the internal fermions.

description: We investigate the global neutral hydrogen (HI) content of isolated galaxies selected from the SDSS spectroscopic survey with optical evidence of Active Galactic Nuclei (AGN). Our sample includes galaxies with unresolved HI observations from the ALFALFA 70% data release combined with deeper HI observations of low-mass galaxies with 7.0 < log(M*) < 9.5. We examine the HI masses of this sample using the distance from the star-forming sequence on the OIII\Hb and NII\Ha Baldwin Phillips Terlevich (BPT) diagram as a measurement of AGN activity. In agreement with previous studies, we find that, for galaxies with log(M*) > 9.5, AGN activity does not correlate with the global HI content. However, for galaxies with 9.2 < log(M*) < 9.5, we identify a set of objects at large distances from the BPT star-forming sequence and lower than expected HI masses. This gas-depleted sample is red in both g-r and NUV-r colors and compact without distinguishable signs of star formation. This is surprising because the vast majority of isolated galaxies in this stellar mass regime are both star-forming and gas-rich. These galaxies are greater than 1.5 Mpc from any massive galaxy, ruling out environmental processes as a source of the gas-depletion. We suggest that either black hole feedback or shocks from extremely bursty star formation cause the emission lines and have destroyed or otherwise consumed the cold gas.

New Methodologies in Transition Metal-Mediated (11C)Radiolabelling for Positron Emission Tomography
Creators: name: Jennings, Lucy
Publisher: name: Imperial College London
Year: 2011

description: This thesis focuses on the requirement for new methodologies to incorporate 11C into biologically active compounds for Positron Emission Tomography (PET). The use of PET has expanded over recent years as a valuable imaging technique for the study of drug delivery as well as the study of neurological diseases and oncology. The short half-life of 11C (20.4 min) limits its use to approximately 1 hour therefore rapid chemistry is required to radiolabel tracer molecules before use in vivo. Chapter 1 includes an overview of the literature in the areas of PET radiochemistry, transition metal-catalysed carbonylation, N-heterocyclic carbenes, hemilabile ligands, titanium and zirconium imido complexes and nickel-/palladium-catalysed carboxylations. Chapters 2 and 3 detail the investigations of a palladium-catalysed carbonylation reaction for the formation of amides commonly found in biologically active compounds. N-benzylbenzamide was synthesised in a model reaction which tested a range of diphosphine ligands and N-heterocyclic carbenes. The best performing systems were taken forward to be tested with [11C]CO in the radiochemistry laboratories at the GSK Clinical Imaging Centre at Hammersmith Hospital with excellent radiochemical purities of [11C]N-benzylbenzamide (99 %) and good radiochemical yields (55 %). Hemilabile phosphorus-thioether (P-S) and phosphorus-ether (P-O) bidentate ligands were also investigated in the synthesis of N-benzylbenzamide and compared to diphosphine ligands in this reaction and new palladium catalysts were prepared with novel P-S ligands. [11C]CO2 was examined as a potentially useful source of [11C] for radiolabelling as research into transition metal-mediated processes to activate CO2 for environmental reasons has grown in recent years. Chapter 4 investigates some recent literature detailing nickel- and palladium-catalysed carboxylation of organozinc halides in the synthesis of carboxylic acids. Titanium and zirconium imido complexes were synthesised with the intention of forming [11C]isocyanate precursors - this work is described in Chapter 5. A range of work has been carried out and potential future studies in all these areas are specified at the end of the thesis.

description: The van der Waals coefficients for the alkali-metal atoms from Na to Fr interacting in their ground states, are calculated using relativistic ab initio methods. The accuracy of the calculations is estimated by also evaluating atomic static electric dipole polarizabilities and coefficients for the interaction of the atoms with a perfectly conducting wall. The results are in excellent agreement with the latest data from ultra-cold collisions and from studies of magnetic field induced Feshbach resonances in Na and Rb. For Cs we provide critically needed data for ultra-cold collision studies.
On the quantum reflection factor for the sinh-Gordon model with general boundary conditions
Creators: name: Chenaghlou, A.
Publisher: name: arXiv
Year: 2000
Subjects: subject: High Energy Physics - Theory (hep-th)
subject: FOS: Physical sciences

description: The one loop quantum corrections to the classical reflection factor of the sinh-Gordon model are calculated partially for general boundary conditions. The model is studied under boundary conditions which are compatible with integrability, and in the framework of the conventional perturbation theory generalized to the affine Toda field theory. It is found that the general form of the related quantum corrections are hypergeometric functions.

description: Jim Mason begins this three session interview discussing his experiences growing up on a farm in Missouri during the 1950s. He analyzes at length the rural outlooks on animals, including in agriculture and hunting. He describes his initial interests in biology, entry into college as a pre-med student, and eventual decision to pursue law career instead. He describes his introduction to animal rights while at law school, and becoming more politically conscious in the 1970s following the death of his wife and as the result of his work as a legal services attorney in Bridgeport, Connecticut. Mason describes the animal rights movement in the 1970s and attending a conference in Cambridge, England. He speaks about research on Animal Factories and the public's response. He also describes the founding of The Animals' Agenda and his eventual departure. He also discusses his writing of An Unnatural Order. Finally, he analyzes activities and characteristics of the animal rights movement in the 1980s, including activist demographics, rallies and actions, factory farming, reaction of the media, and strategies. The interview is accompanied by one box of attachments, including writings by Mason and issues of The Animals' Agenda.
Rigorous asymptotics of a KdV soliton gas

description: We analytically study the long time and large space asymptotics of a new broad class of solutions of the KdV equation introduced by Dyachenko, Zakharov, and Zakharov. These solutions are characterized by a Riemann--Hilbert problem which we show arises as the limit $N\to \infty$ of a gas of $N$-solitons. We show that this gas of solitons in the limit $N \to \infty$ is slowly approaching a cnoidal wave solution for $x \to - \infty$ (up to terms of order $\mathcal{O} (1/x)$), while approaching zero exponentially fast for $x\to+\infty$. We establish an asymptotic description of the gas of solitons for large times that is valid over the entire spatial domain, in terms of Jacobi elliptic functions.

description: Microemulsification and blending of commercial diesel is under constant research for possible fuel application. Microemulsions (ME) were prepared using diesel (D), kerosene (K), diesel and kerosene mixtures at various proportions (D + K) (oil phase: O), Triton X-100 surfactant (S), n-butanol, isobutanol (i-butanol), n-pentanol and n-octanol cosurfactants (C), and aqueous phase (W) containing water or brine for the study. Electrical conductance studies and temperature-induced separation of phase have been adopted for recognizing the o/w, w/o and bicontinuous zones. Dye probing has been done to explain the mass transfer among these phases. Percent of solubilization of oil in water has been enumerated in some of the ME. The possible fuel applications of the microemulsions are predicted from their density and flame brightness.

Jet Dynamics in Compact Object Mergers: GW170817 Likely had a Successful Jet

description: We use relativistic hydrodynamic numerical calculations to study the interaction between a jet and a homologous outflow produced dynamically during binary neutron star mergers. We quantify how the thermal energy supplied by the jet to the ejecta and the ability of a jet to escape the homologous ejecta depend on the parameters of the jet engine and the ejecta. For collimated jets initiated at early times compared to the engine duration, we show that successful breakout of the forward cocoon shock necessitates a jet that successfully escapes the ejecta. This is because the ejecta is expanding and absorbing thermal energy, so that the forward shock from a failed jet stalls before it reaches the edge of the ejecta. This conclusion can be circumvented only for very energetic wide angle jets, with parameters that are uncomfortable given short-duration GRB observations. For successful jets, we find two regimes of jet breakout from the ejecta, early breakout on timescales shorter than the engine duration, and late breakout well after the engine shuts off. A late breakout can explain the observed delay between gravitational waves and gamma rays in GW 170817. We show that for the entire parameter space of jet parameters surveyed here (covering energies $\sim 10^{48}-10^{51}$ ergs and opening angles $θ_j \sim 0.07-0.4$) the thermal energy deposited into the ejecta by the jet propagation is less than that produced by r-process heating on second timescales by a factor of $\gtrsim 10$. Shock heating is thus energetically subdominant in setting the luminosity of thermally powered transients coincident with neutron star mergers (kilonovae). For typical short GRB jet parameters, our conclusion is stronger: there is little thermal energy in the cocoon, much less than what is needed to explain the early blue component of the kilonova in GW 170817.

description: Graphene quantum dots (GQDs) have been prepared from graphene oxide (GO) and characterized by standard analytical techniques. The size of the prepared GQDs ranges from 2-10 nm. Aqueous dispersion of GQDs exhibited excitation-dependent emission behavior. Emission intensity of the aqueous dispersion found stable for the examined duration of about four months. GQDs exhibited selective recognition of Fe3+ and Cr3+ out of various common ions such as alkali, alkaline-earth and transition metal ions in aqueous medium through fluorescence quenching. The lower limit of detection of Fe3+ is 1 µM and that of Cr3+ is 4 µM.
Pair correlation function of an inhomogeneous interacting Bose-Einstein condensate

description: We calculate the pair correlation function of an interacting Bose gas in a harmonic trap directly via Path Integral Quantum Monte Carlo simulation for various temperatures and compare the numerical result with simple approximative treatments. Around the critical temperature of Bose-Einstein condensation, a description based on the Hartree-Fock approximation is found to be accurate. At low temperatures the Hartree-Fock approach fails and we use a local density approximation based on the Bogoliubov description for a homogeneous gas. This approximation agrees with the simulation results at low temperatures, where the contribution of the phonon-like modes affects the long range behavior of the correlation function. Further we discuss the relation between the pair correlation and quantities measured in recent experiments.
