description: The experimentally measured phase diagram of cuprate superconductors in the temperature-applied magnetic field plane illuminates key issues in understanding the physics of these materials. At low temperature, the superconducting state gives way to a long-range charge order with increasing magnetic field; both the orders coexist in a small intermediate region. The charge order transition is strikingly insensitive to temperature, and quickly reaches a transition temperature close to the zero-field superconducting $T_c$. We argue that such a transition along with the presence of the coexisting phase cannot be described simply by a competing orders formalism. We demonstrate that for some range of parameters there is an enlarged symmetry of the strongly coupled charge and superconducting orders in the system depending on their relative masses and the coupling strength of the two orders. We establish that this sharp switch from the superconducting phase to the charge order phase can be understood in the framework of a composite SU(2) order parameter comprising the charge and superconducting orders. Finally, we illustrate that there is a possibility of the coexisting phase of the competing charge and superconducting orders only when the SU(2) symmetry between them is weakly broken due to biquadratic terms in the free energy. The relation of this sharp transition to the proximity to the pseudogap quantum critical doping is also discussed.
The behaviour of spent nuclear fuel in wet interim storage
Creators: name: Howett, Elizabeth
Publisher: name: Lancaster University
Year: 2019

description: The UK is currently transitioning from a closed nuclear fuel cycle to an open cycle. During this transition, wet interim storage of AGR spent nuclear fuel in the UK will be extended until a long term disposal facility becomes operational. The current THORP Receipt and Storage pond is to be converted into an interim storage facility. Spent fuel will be more densely packed in this pond to accommodate current and future spent nuclear fuel. There will a resulting rise in pond water temperature from 24 ◦C to between 45-60 ◦C. This necessitates further research into the long term stability of stored spent nuclear fuel. This thesis describes the corrosion behaviour of AGR fuel cladding and AGR spent fuel under conditions relevant to the lengthened storage periods. An electrochemical study of the corrosion behaviour of unirradiated and unsensitised 20/25/Nb stainless steel under alkaline spent nuclear fuel interim storage pond water conditions is presented. The results give preliminary indications that dosing pond water to a pH'11.4, with an expected chloride concentration of ∼1 ppm and hydrogen peroxide concentration of ∼1 ppm, provides corrosion protection to unstressed cladding samples at the temperatures studied, 24 ◦C (current conditions), 45 ◦C (projected future pond temperature) and 60 ◦C (predicted peak operating conditions). Analogues for fuel cladding affected by radiation induced sensitisation were developed by the National Nuclear Laboratory. For both heat treated 20/25/Nb stainless steel and heat treated 304H stainless steel, experiments provide initial evidence that for sensitised 20/25/Nb SS dosing pond water to a pH'11.4, with an expected chloride concentration of ∼1 ppm and hydrogen peroxide concentration of ∼1 ppm, will lead to the passivation of the cladding surface for pond water temperatures between 24 and 60 ◦C. However general corrosion rates are higher than those of the unsensitised counterparts and spent fuel stringers likely to be affected by RIS should be monitored more closely. In the unlikely event that the fuel cladding is perforated, the fuel itself will be exposed to pond water. Thus in order to assist in the generation of a thorough safety case, the corrosion of pure UO2 and AGR SIMFuels was studied under conditions typical of those found in interim spent fuel storage pond waters. With respect to the dissolution of spent fuel, it appears to be advantageous to dose the ponds to pH'11.4. The alkaline conditions in the pond water suppress the dissolution as UO2+ 2 which may otherwise occur. A U3O7/U4O9 oxide layer is predicted to be developing on the surface of the samples at the open circuit potentials, for the samples exposed to simulant pond water.

description: The N/Z dependence of projectile fragmentation at relativistic energies has been studied in a recent experiment at the GSI laboratory with the ALADiN forward spectrometer coupled to the LAND neutron detector. Besides a primary beam of 124Sn, also secondary beams of 124La and 107Sn delivered by the FRS fragment separator have been used in order to extend the range of isotopic compositions of the produced spectator sources. With the achieved mass resolution of ΔA/A \approx 1.5%, lighter isotopes with atomic numbers Z \le 10 are individually resolved. The presently ongoing analyses of the measured isotope yields focus on isoscaling and its relation to the properties of hot fragments at freeze-out and on the derivation of chemical freeze-out temperatures which are found to be independent of the isotopic composition of the studied systems. The latter result is at variance with the predictions for limiting temperatures as obtained with finite-temperature Hartree-Fock calculations.

The Beneficial Pleiotropic Role of Tumour Necrosis Factor Related Apoptosis Inducing Ligand (TRAIL) in Cardiovascular Disease

Subjects: Uncategorized

description: Background: Cardiovascular disease (CVD) remains the leading cause of death in patients with Type 2 diabetes mellitus (T2DM). Tumour necrosis factor related apoptosis inducing ligand (TRAIL) is a type II transmembrane protein that belongs to the tumour necrosis factor (TNF) superfamily. A growing body of clinical and animal studies highlight TRAILs vasoprotective potential, with TRAIL being linked to myocardial infarction and accelerated vascular calcification, whereas exogenous TRAIL administration exhibits anti-atherosclerotic activity. Throughout these studies, mechanistic information on the precise nature of TRAIL-mediated protection and the identity of the molecular/cellular targets of TRAIL is still extremely limited. The aims of this thesis were to characterise the effects of TRAIL on endothelial cells, as endothelial dysfunction is an important aspect of the atherosclerotic disease process, and to assess the suitability of TRAIL as marker of cardiovascular risk in patients with T2DM. Methods: We examined the effect of TRAIL on various end-points in human aortic endothelial cells (HAECs) in basal and injurious conditions. In tandem with our in vitro investigations, we compared serum TRAIL levels in non-diabetic controls, patients with T2DM and patients with T2DM and CVD. Results: TRAIL reduced oxidative stress in HAECs exposed to the pro-atherogenic conditions induced by oscillatory shear stress (OSS) and pro-inflammatory cytokines. Serum TRAIL was significantly lower in patients with T2DM and CVD compared to patients with T2DM alone or non-diabetic controls. TRAIL predicted the presence of CVD in patients with T2DM with adequate sensitivity and specificity. Conclusions: TRAILs vasoprotective effects in the vasculature are at least partly mediated by its ability to reduce oxidative stress. Pending further investigations in larger trials, serum TRAIL seems to be a useful diagnostic biomarker of clinically relevant CVD in patients with T2DM.

Electromagnetic Polarisability of the Nucleon in Chiral Perturbation Theory

description: We compute the polarisability of the nucleon to leading order in chiral perturbation theory. The contributions from kaons and baryon resonances as intermediate states are included in addition to the contribution from pions and nucleons that had been previously computed. The isoscalar operators are dominated by the infrared behaviour of pion loops giving rise to a $1/m_π$ coefficient. In contrast, the isovector operators are dominated by loops involving kaons, giving a $1/m_{k}$ coefficient, and further demonstrates that the strange quark is an important component of the nucleon. In addition, the inclusion of the decuplet of baryon resonances as intermediate states substantially modifies the result found from the octet baryons alone for the isoscalar polarisability.

Noncommutativity in space-time extended by Liouville field

Year: 2007

description: The world-sheet quantum conformal invariance can be realized in the presence of the conformal factor $F$, by inclusion of Liouville term. In the background with linear dilaton field, $Φ(x)=Φ_0+a_μx^μ$, the field $F$ becomes a new noncommutative variable. Therefore, it is natural to extend space-time with a new coordinate, $F$, in order to unify expressions for noncommutativity parameter $Θ^{ij}$ of the space-time coordinates $x^i$, with the part $Θ^i$ connecting noncommutativity between coordinates $x^i$ and $F$. In this way we solve the problems of Dp-brane noncommutativity in a more elegant way. The technical advantage uses the fact that in the extended space-time the action with dilaton field can be rewritten in dilaton free form. We use canonical method and extend its application to the derivation of boundary conditions. From requirement that Hamiltonian, as the time translation generator, has well defined derivatives in the coordinates and momenta, we obtain boundary conditions directly in the canonical form.

Equivalent Theories and Changing Hamiltonian Observables in General Relativity

description: Change and local spatial variation are missing in Hamiltonian General Relativity according to the most common definition of observables (0 Poisson bracket with all first-class constraints). But other definitions have been proposed. Seeking Hamiltonian-Lagrangian equivalence, Pons, Salisbury and Sundermeyer use the Anderson-Bergmann-Castellani gauge generator G, a tuned sum of first-class constraints. Kuchař waived the 0 Poisson bracket condition for the Hamiltonian constraint to achieve changing observables. A systematic combination of the two reforms might use the gauge generator but permit non-zero Lie derivative Poisson brackets. One can test definitions by calculation using two formulations of a theory, one without gauge freedom and one with it, which must have equivalent observables. For de Broglie-Proca non-gauge massive electromagnetism, all constraints are second-class, so everything is observable. Demanding equivalent observables from gauge Stueckelberg-Utiyama electromagnetism, one finds that the usual definition fails while the Pons-Salisbury-Sundermeyer definition with G succeeds. This definition does not readily yield change in GR, however. Should GR's external gauge freedom of General Relativity share with internal gauge symmetries the 0 Poisson bracket (invariance), or is covariance (a transformation rule) sufficient? A graviton mass breaks the gauge symmetry (general covariance), but it can be restored by parametrization with clock fields. By requiring equivalent observables, one vindicates the Lie derivative as the Poisson bracket of observables with the gauge generator G.

How Cosmic Background Correlations at Large Angles Relate to Mass Autocorrelations in Space

Year: 1994

description: The Sachs-Wolfe effect is known to produce large angular scale fluctuations in the Cosmic Microwave Background Radiation (CMBR) due to gravitational potential fluctuations. We show how the angular correlation function of the CMBR can be expressed explicitly in terms of the mass autocorrelation function $ξ(r)$ in the Universe. We derive analytic expressions for the angular correlation function and its multipole moments in terms of integrals over $ξ(r)$ or its second moment, $J_3 (r)$, which does not need to satisfy the sort of integral constraint that $ξ(r)$ must. We derive similar expressions for bulk flow velocity in terms of $ξ$ and $J_3$. One interesting result that emerges directly from this analysis is that, for angles $θ$, there is a substantial contribution to the correlation function from a wide range of distance $r$ and that the radial shape of this contribution does not vary greatly with angle.

description: Gl 758 B is a late-T dwarf orbiting a metal-rich Sun-like star at a projected separation of $ρ$ $\approx$ 1.6" (25 AU). We present four epochs of astrometry of this system with NIRC2 at Keck Observatory spanning 2010 to 2017 together with 630 radial velocities (RVs) of the host star acquired over the past two decades from McDonald Observatory, Keck Observatory, and the Automated Planet Finder at Lick Observatory. The RVs reveal that Gl 758 is accelerating with an evolving rate that varies between 2-5 m s$^{-1}$ yr$^{-1}$, consistent with the expected influence of the imaged companion Gl 758 B. A joint fit of the RVs and astrometry yields a dynamical mass of 42$^{+19}_{-7}$ M$_\mathrm{Jup}$ for the companion with a robust lower limit of 30.5 M$_\mathrm{Jup}$ at the 4-$σ$ level. Gl 758 B is on an eccentric orbit ($e$ = 0.26-0.67 at 95% confidence) with a semimajor axis of $a$ = $21.1_{-1.3}^{+2.7}$ AU and an orbital period of $P$ = $96_{-9}^{+21}$ yr, which takes it within $\approx$9 AU from its host star at periastron passage. Substellar evolutionary models generally underpredict the mass of Gl 758 B for nominal ages of 1-6 Gyr that have previously been adopted for the host star. This discrepancy can be reconciled if the system is older---which is consistent with activity indicators and recent isochrone fitting of the host star---or alternatively if the models are systematically overluminous by $\approx$0.1-0.2 dex. Gl 758 B is currently the lowest-mass directly imaged companion inducing a measured acceleration on its host star. In the future, bridging RVs and high-contrast imaging with the next generation of extremely large telescopes and space-based facilities will open the door to the first dynamical mass measurements of imaged exoplanets.

description: The homogeneous, isotropic, and flat $Λ$CDM universe favored by observations of the cosmic microwave background can be described using only Euclidean geometry, locally correct Newtonian mechanics, and the basic postulates of special and general relativity. We present simple derivations of the most useful equations connecting astronomical observables (redshift, flux density, angular diameter, brightness, local space density,...) with the corresponding intrinsic properties of distant sources (lookback time, distance, spectral luminosity, linear size, specific intensity, source counts,...). We also present an analytic equation for lookback time that is accurate within 0.1% for all redshifts $z$. The exact equation for comoving distance is an elliptic integral that must be evaluated numerically, but we found a simple approximation with errors $< 0.2$% for all redshifts up to $z \approx 50$.

description: The energy--momentum radiated in gravitational waves by an isolated source is given by a formula of Bondi. This formula is highly non--local: the energy--momentum is not given as the integral of a well--defined local density. It has therefore been unclear whether the Bondi formula can be used to get information from gravity--wave measurements. In this note, we obtain, from local knowledge of the radiation field, a lower bound on the Bondi flux.

description: We study the dynamics of 2+1 dimensional theories with ${\cal N}=1$ supersymmetry. In these theories the supersymmetric ground states behave discontinuously at co-dimension one walls in the space of couplings, with new vacua coming in from infinity in field space. We show that the dynamics near these walls is calculable: the two-loop effective potential yields exact results about the ground states near the walls. Far away from the walls the ground states can be inferred by decoupling arguments. In this way, we are able to follow the ground states of ${\cal N}=1$ theories in 2+1 dimensions and construct the infrared phases of these theories. We study two examples in detail: Adjoint SQCD and SQCD with one fundamental quark. In Adjoint QCD we show that for sufficiently small Chern-Simons level the theory has a non-perturbative metastable supersymmetry-breaking ground state. We also briefly discuss the critical points of this theory. For SQCD with one quark we establish an infrared duality between a $U(N)$ gauge theory and an $SU(N)$ gauge theory. The duality crucially involves the vacua that appear from infinity near the walls.

description: We consider the problem of random sampling for band-limited functions. When can a band-limited function $f$ be recovered from randomly chosen samples $f(x_j), j\in \mathbb{N}$? We estimate the probability that a sampling inequality of the form A\|f\|_2^2 \leq \sum_{j\in \mathbb{N}} |f(x_j)|^2 \leq B \|f\|_2^2 hold uniformly all functions $f\in L^2(\mathbb{R}^d)$ with supp $\hat{f} \subseteq [-1/2,1/2]^d$ or some subset of \bdl functions. In contrast to discrete models, the space of band-limited functions is infinite-dimensional and its functions "live" on the unbounded set $\mathbb{R}^d$. This fact raises new problems and leads to both negative and positive results. (a) With probability one, the sampling inequality fails for any reasonable definition of a random set on $\mathbb{R}^d$, e.g., for spatial Poisson processes or uniform distribution over disjoint cubes. (b) With overwhelming probability, the sampling inequality holds for certain compact subsets of the space of band-limited functions and for sufficiently large sampling size.

description: Introduction Surgical patients are particularly at risk of healthcare associated infection (H C A I) by virtue of the presence of a surgical site leading to surgical site infections (S S I) and because of the need for intravascular access resulting in catheter-related bloodstream infection (C R B S I). Methods A two-year initiative commenced with an initial audit of surgical practice which was used to inform the development of a targeted educational initiative by surgeons specific for surgical trainees. Parameters assessed during initial and repeat audits after the educational initiative included intra- and post-operative aspects of the prevention o f S S I as well as the care of peripheral venous cannulae (P V C ) in surgical patients. Results The proportion of prophylactic antibiotics administered pre-incision across 360 operations increased from 30% to 59.1% (p Conclusion Significant improvements were seen in surgical practice in S S I and C R B S I prevention through a focused educational programme developed by and for surgeons.

description: Frequentist and Bayesian phase estimation strategies lead to conceptually different results on the state of knowledge about the true value of the phase shift. We compare the two frameworks and their sensitivity bounds to the estimation of an interferometric phase shift limited by quantum noise, considering both the cases of a fixed and a fluctuating parameter. We point out that frequentist precision bounds, such as the Cramèr-Rao bound, for instance, do not apply to Bayesian strategies and vice-versa. Similarly, bounds for fluctuating parameters make no statement about the estimation of a fixed parameter.

description: We explore the possibility of describing our universe with a singularity--free, closed, spatially homogeneous and isotropic cosmological model, using only general relativity and a suitable equation of state which produces an inflationary era. A phase transition to a radiation--dominated era occurs as a consequence of boundary conditions expressing the assumption that the temperature cannot exceed the Planck value. We find that over a broad range of initial conditions, the predicted value of the Hubble parameter is approximately $47$ km$\cdot$~s$^{-1}\cdot$~Mpc$^{-1}$. Inflation is driven by a scalar field, which must be conformally coupled to the curvature if the Einstein equivalence principle has to be satisfied. The form of the scalar field potential is derived, instead of being assumed a priori.

description: Chronic exposure of oesophageal mucosa to bile has been implicated in the etiology of the oesophageal lesions which develop into Barrett's oesophagus.Loss of the gallbladder reservoir function at cholecystectomy may critically alter the dynamics of bile storage and release. In our first study we aimed to investigate the prevalence of bile reflux in three patient populations; symptomatic controls, Barrett's patients and patients post oesophago-gastric resection for carcinoma. Augmentation of bile reflux was noted in patients who had previous history of cholecystectomy. A high proportion of patients remained symptomatic post-cholecystectomy and a high proportion of these still-symptomatic post-cholecystectomy patients had increased bile reflux index. In our second retrospective study we examined the effects of cholecystectomy on gastric and oesophageal mucosa at molecular and histological level. There was an increase in bile reflux index, Ki67 and p53 in post-cholecystectomy patients. This raised concern about development of pre-malignant changes in these patients. In the third study, the effect of cholecystectomy on gastric and oesophageal microenvironment was evaluated prospectively. This study noted the histological and molecular changes precipitated by cholecystectomy are similar to those identified as precursors of Barrett's oesophagus. Such concerning changes suggest that options other than cholecystectomy be considered for patients with gallstones in a functioning gallbladder.
Endothelial progenitor cells in mothers of low birthweight infants : a link between defective placentation and increased cardiovascular risk.

description: Aims: This study tested the hypothesis that endothelial progenitor cell (EPC) pathology provides a unifying explanation for the tendency to carry low birthweight babies and subsequent increased maternal cardiovascular risk. Methods: We measured maternal EPC number and function, conventional cardiovascular risk markers, and cord blood adiponectin in 23 small for gestational age (SGA; birthweightcentile) and 23 appropriate for gestational age (AGA; birthweight >10th centile) pregnancies. Results: Median EPC count was lower (294 vs. 367, p=0.005), and EPC migratory capability was reduced (migration index 0.91 vs. 1.59, p Conclusions: Giving birth to a SGA infant was associated with lower maternal EPC number and reduced migratory function in vitro. EPC pathology may explain both uteroplacental insufficiency, leading to low birthweight, and future cardiovascular disease in the mother. SGA infants had lower cord blood adiponectin, potentially representing a mechanism for future cardiovascular disease in later life of the infant.

In general, the Young et al. algorithm resulted in higher predicted utilities indicating the trend of better HRQoL compared with the Kent et al. algorithm. In addition, application of the French tariffs resulted in lower predicted utility values than the UK tariffs.
Orbital alignment of circumbinary planets that form in misaligned circumbinary discs: the case of Kepler-413b

description: Although most of the circumbinary planets detected by the Kepler spacecraft are on orbits that are closely aligned with the binary orbital plane, the systems Kepler-413 and Kepler-453 exhibit small misalignments of $\sim 2.5^\circ$. One possibility is that these planets formed in a circumbinary disc whose midplane was inclined relative to the binary orbital plane. Such a configuration is expected to lead to a warped and twisted disc, and our aim is to examine the inclination evolution of planets embedded in these discs. We employed 3D hydrodynamical simulations that examine the disc response to the presence of a modestly inclined binary with parameters that match the Kepler-413 system, as a function of disc parameters and binary inclinations. The discs all develop slowly varying warps, and generally display very small amounts of twist. Very slow solid body precession occurs because a large outer disc radius is adopted. Simulations of planets embedded in these discs resulted in the planet aligning with the binary orbit plane for disc masses close to the minimum mass solar nebular, such that nodal precession of the planet was controlled by the binary. For higher disc masses, the planet maintains near coplanarity with the local disc midplane. Our results suggest that circumbinary planets born in tilted circumbinary discs should align with the binary orbit plane as the disc ages and loses mass, even if the circumbinary disc remains misaligned from the binary orbit. This result has important implications for understanding the origins of the known circumbinary planets.

description: Perovskite solar cells combine high carrier mobilities with long carrier lifetimes and high radiative efficiencies. Despite this, full devices suffer from significant nonradiative recombination losses, limiting their VOC to values well below the Shockley–Queisser limit. Here, recent advances in understanding nonradiative recombination in perovskite solar cells from picoseconds to steady state are presented, with an emphasis on the interfaces between the perovskite absorber and the charge transport layers. Quantification of the quasi‐Fermi level splitting in perovskite films with and without attached transport layers allows to identify the origin of nonradiative recombination, and to explain the VOC of operational devices. These measurements prove that in state‐of‐the‐art solar cells, nonradiative recombination at the interfaces between the perovskite and the transport layers is more important than processes in the bulk or at grain boundaries. Optical pump‐probe techniques give complementary access to the interfacial recombination pathways and provide quantitative information on transfer rates and recombination velocities. Promising optimization strategies are also highlighted, in particular in view of the role of energy level alignment and the importance of surface passivation. Recent record perovskite solar cells with low nonradiative losses are presented where interfacial recombination is effectively overcome—paving the way to the thermodynamic efficiency limit.

description: Invited presentation in Deakin University’s Contemporary Histories Research Group History Seminar Series The practice of historical research has been changed by the large volume of cultural heritage collections now available online. But as we celebrate the convenience of digital access, we also need to be aware of how ‘access’ itself is constructed and constrained — what is ‘accessible’ and why? In this seminar I want to explore hacking as a method for asking critical questions about cultural heritage collections. As historians, I’ll suggest, we should be prepared to engage not just with sources delivered through online systems, but with the technical, political, and bureaucratic processes that create such systems. To do this, we need to turn interfaces against themselves and understand what they hide as well as what they reveal.

description: The entropy growth in a cosmological process of pair production is completely determined by the associated squeezing parameter, and is insensitive to the number of particles in the initial state. The total produced entropy may represent a significant fraction of the entropy stored today in the cosmic black-body radiation, provided pair production originates from a change in the background metric at a curvature scale of the Planck order.

Correlated spectral variability in brown dwarfs

Subjects: subject: Astrophysics (astro-ph)

description: Models of brown dwarf atmospheres suggest they exhibit complex physical behaviour. Observations have shown that they are indeed dynamic, displaying small photometric variations over timescales of hours. Here I report results of infrared (0.95-1.64 micron) spectrophotometric monitoring of four field L and T dwarfs spanning timescales of 0.1-5.5 hrs, the goal being to learn more about the physical nature of this variability. Spectra are analysed differentially with respect to a simultaneously observed reference source in order to remove Earth-atmospheric variations. The variability amplitude detected is typically 2-10%, depending on the source and wavelength. I analyse the data for correlated variations between spectral indices. This approach is more robust than single band or chisq analyses, because it does not assume an amplitude for the (often uncertain) noise level (although the significance test still assumes a shape for the noise power spectrum). Three of the four targets show significant evidence for correlated variability. Some of this can be associated with specific features including Fe, FeH, VO and KI, and there is good evidence for intrinsic variability in water and possibly also methan. Yet some of this variability covers a broader spectral range which would be consistent with dust opacity variations. The underlying common cause is plausibly localized temperature or composition fluctuations caused by convection. Looking at the high signal-to-noise ratio stacked spectra we see many previously identified spectral features of L and T dwarfs, such as KI, NaI, FeH, water and methane. In particular we may have detected methane absorption at 1.3-1.4 micron in the L5 dwarf SDSS 0539-0059.
