description: Boost-rotation symmetric spacetimes are the only locally asymptotically flat axially symmetric electrovacuum spacetimes with a further symmetry that are radiative. They are realized by uniformly accelerated particles of various kinds or black holes. Their general properties are summarized. Several examples of boost-rotation symmetric solutions of the Maxwell and Einstein equations are studied: uniformly accelerated electric and magnetic multipoles, the Bonnor-Swaminarayan solutions, the C-metric and the spinning C-metric.

description: Cosmologies based on General Relativity encompassing an anti-symmetric connection (torsion) can display nice desirable features as the absence of the initial singularity and the possibility of inflation in the early stage of the universe. After briefly reviewing the standard approach to the cosmology with torsion, we generalize it to demonstrate that several theories of torsion gravity are possible using different choices of the diffeomorphic invariants in the Lagrangians. As a result, distinct cosmologies emerge. In all of them it is possible that the universe avoids the initial singularity and passes through an initial accelerated expansion. Differences between these theories are highlighted.

Transformation Kinetics on Mechanical Alloying

Year: 2001
Subjects: subject: Materials Science (cond-mat.mtrl-sci)

description: We propose and develop a model as an attempt to describe the local mechanism of mechanical alloying. This model is based on the observation of global parameters, such as the volumes of the various phases present in the material, and their transformations during the process. The model is applied to milled Fe-Cu and Fe-N experimental results obtained in previous works. In the milling of Fe-Cu system, four stages, whose features are in accordance with experimental observation, are identified:(i) energy storage; (ii) start of the reaction and speed up of it; (iii) decrease of the reaction rate and (iv) stationary stage. No energy storage stage is observed and no saturation is achieved in the milling of Fe-N system. Moreover, we propose a modification on the global kinetic law introduced by Matteazzi et al. based on the different nature of Fe-Cu and Fe-N systems. This modification allows the extension of the validity of this law.

description: The discovery of a repeating Fast Radio Burst (FRB) source, FRB 121102, eliminated models involving cataclysmic events for this source. No other repeating FRB has yet been detected in spite of many recent FRB discoveries and follow-ups, suggesting repeaters may be rare in the FRB population. Here we report the detection of six repeat bursts from FRB 180814.J0422+73, one of the 13 FRBs detected by the Canadian Hydrogen Intensity Mapping Experiment (CHIME) FRB project during its pre-commissioning phase in July and August 2018. These repeat bursts are consistent with originating from a single position on the sky, with the same dispersion measure (DM), ~189 pc cm-3. This DM is approximately twice the expected Milky Way column density, and implies an upper limit on the source redshift of 0.1, at least a factor of ~2 closer than FRB 121102. In some of the repeat bursts, we observe sub-pulse frequency structure, drifting, and spectral variation reminiscent of that seen in FRB 121102, suggesting similar emission mechanisms and/or propagation effects. This second repeater, found among the first few CHIME/FRB discoveries, suggests that there exists -- and that CHIME/FRB and other wide-field, sensitive radio telescopes will find -- a substantial population of repeating FRBs.

R-Modes in Superfluid Neutron Stars

description: The analogs of r-modes in superfluid neutron stars are studied here. These modes, which are governed primarily by the Coriolis force, are identical to their ordinary-fluid counterparts at the lowest order in the small angular-velocity expansion used here. The equations that determine the next order terms are derived and solved numerically for fairly realistic superfluid neutron-star models. The damping of these modes by superfluid ``mutual friction'' (which vanishes at the lowest order in this expansion) is found to have a characteristic time-scale of about 10^4 s for the m=2 r-mode in a ``typical'' superfluid neutron-star model. This time-scale is far too long to allow mutual friction to suppress the recently discovered gravitational radiation driven instability in the r-modes. However, the strength of the mutual friction damping depends very sensitively on the details of the neutron-star core superfluid. A small fraction of the presently acceptable range of superfluid models have characteristic mutual friction damping times that are short enough (i.e. shorter than about 5 s) to suppress the gravitational radiation driven instability completely.

description: Direct exposure to natural disasters is associated with increased mental disorders. Help-seeking behaviour among Chinese adults is low and the barriers and facilitators of help-seeking among Chinese adults exposed to natural disasters is understudied. Using a person-centred approach, this study describes help-seeking preferences and their correlates in a sample of Chinese college students after experiencing Typhoon Hato, the strongest storm to affect Macao, China in the past 50 years. The baseline sample was collected one month following exposure to the Typhoon (September 2017). Six months following the baseline study (April, 2018), a total of 815 students (females = 71.5%) completed follow-up and were included in the data analysis. Latent Class Analysis (LCA) and Multinomial Logistic Regression were used to analyse the data via Mplus 7.4 and Stata 15.0. Three latent classes of help-seeking preferences were identified in this study, including: ‘mental health professionals and close people’ (MHPCP, 52%), non-seekers (31%), and ‘multiple sources’ (17%). The results of multinomial logistic regression showed that region of origin (mainland versus Macao, China), self-stigma, perceived helpfulness of professional mental health help, previous professional help-seeking behaviour, and perceived social support, were significantly associated with MHPCP help-seeking preferences. A large proportion of students preferred to seek support from loved ones and professionals. However, over 30% of the sample preferred not seeking help for mental health concerns. Further research is needed to enhance mental health treatment seeking preferences among Chinese college students.

description: We propose several generalized linear models (GLMs) to predict the number of successful cyber intrusions (or "intrusions") into an organization's computer network, where the rate at which intrusions occur is a function of the following observable characteristics of the organization: (i) domain name server (DNS) traffic classified by their top-level domains (TLDs); (ii) the number of network security policy violations; and (iii) a set of predictors that we collectively call "cyber footprint" that is comprised of the number of hosts on the organization's network, the organization's similarity to educational institution behavior (SEIB), and its number of records on scholar.google.com (ROSG). In addition, we evaluate the number of intrusions to determine whether these events follow a Poisson or negative binomial (NB) probability distribution. We reveal that the NB GLM provides the best fit model for the observed count data, number of intrusions per organization, because the NB model allows the variance of the count data to exceed the mean. We also show that there are restricted and simpler NB regression models that omit selected predictors and improve the goodness-of-fit of the NB GLM for the observed data. With our model simulations, we identify certain TLDs in the DNS traffic as having significant impact on the number of intrusions. In addition, we use the models and regression results to conclude that the number of network security policy violations are consistently predictive of the number of intrusions.

description: To provide stable and responsive public SPARQL query services, data providers enforce quotas on server usage. Queries which exceed these quotas are interrupted and deliver partial results. Such interruption is not an issue if it is possible to resume queries execution afterward. Unfortunately, there is no preemption model for the Web that allows for suspending and resuming SPARQL queries. In this paper, we propose SaGe: a SPARQL query engine based on Web preemption. SaGe allows SPARQL queries to be suspended by the Web server after a fixed time quantum and resumed upon client request. Web preemption is tractable only if its cost in time is negligible compared to the time quantum. The challenge is to support the full SPARQL query language while keeping the cost of preemption negligible. Experimental results demonstrate that SaGe outperforms existing SPARQL query processing approaches by several orders of magnitude in term of the average total query execution time and the time for first results.

description: In this study strain hardening effect and correlation between chemical composition and mechanical properties of low carbon steels has been investigated. At the first part the correlation between chemical composition and mechanical properties was studied, statistical regression analysis on low carbon steel data. At the second part, strain hardening effect on low carbon steel wires, has been studied by means of tension at different tension rates. During the second phase half of the samples were aged. At the final phase, for all the samples, tension tests were employed to evaluate the mechanical properties. The results show reduction on elongation and cross section and also an increase in yield and tensile stress.

description: Topologically gapless edge states, characterized by topological invariants and Berry's phases of bulk energy bands, provide amazing techniques to robustly control the reflectionless propagation of electrons, photons and phonons. Recently, a new family of topological phases, dictated by the bulk polarization, has been observed, leading to the discovery of the higher-order topological insulators (HOTIs). So far, the HOTIs are only demonstrated in discrete mechanical and electromagnetic systems and electrical circuits with the quantized quadrupole polarization. Here, we realize the higher-order topological states in a two-dimensional (2D) continuous elastic system whose energy bands can be well described. We experimentally observe the gapped one-dimensional (1D) edge states, the trivially gapped zero-dimensional (0D) corner states and the topologically protected 0D corner states. Compared with the trivial corner modes, the topological ones, immunizing against defects, are robustly localized at the obtuse-angled but not the acute-angled corners. The topological shape-dependent corner states open a new route for the design of the topologically-protected but reconfigurable 0D local eigenmodes and provide an excellent platform for the topological transformation of elastic energy among 2D bulk, 1D edge and 0D corner modes.

description: Porous poly(ionic liquid)s (PILs) recently have been actively serving as a multifunctional, interdisciplinary materials platform in quite a few research areas, including separation, catalysis, actuator, sensor, and energy storage, just to name a few. In this context, the capability to photo-pattern PIL microstructures in a porous state on a substrate is still missing but is a crucial step for their real industrial usage. Here, we developed a method for in situ rapid patterning of porous PIL microstructures via a maskless photolithography approach coupled with a simple electrostatic complexation treatment. This breakthrough enables designs of miniaturized sensors. As exemplified in this work, upon loading Pt nanoparticles into porous PIL microstructures, the hybrid sensor showed outstanding performance, bearing both a high sensitivity and a wide detection range.

Harmonic Vibrational Excitations in Disordered Solids and the "Boson Peak"

description: We consider a system of coupled classical harmonic oscillators with spatially fluctuating nearest-neighbor force constants on a simple cubic lattice. The model is solved both by numerically diagonalizing the Hamiltonian and by applying the single-bond coherent potential approximation. The results for the density of states $g(ω)$ are in excellent agreement with each other. As the degree of disorder is increased the system becomes unstable due to the presence of negative force constants. If the system is near the borderline of stability a low-frequency peak appears in the reduced density of states $g(ω)/ω^2$ as a precursor of the instability. We argue that this peak is the analogon of the "boson peak", observed in structural glasses. By means of the level distance statistics we show that the peak is not associated with localized states.

description: It has been suggested by Israel that the Kerr singularity cannot be strong in the sense of Tipler, for it tends to cause repulsive effects. We show here that, contrary to that suggestion, nearly all null geodesics reaching this singularity do in fact terminate in Tipler's strong curvature singularity. Implications of this result are discussed in the context of an earlier cosmic censorship theorem which constraints the occurrence of Kerr-like naked singularities in generic collapse situations.

description: Binary post-asymptotic giant branch (post-AGB) stars are thought to be the products of a strong but poorly-understood interaction during the AGB phase. The aim of this contribution is to update the orbital elements of a sample of galactic post-AGB binaries observed in a long-term radial-velocity monitoring campaign. Radial velocities are computed from high signal-to-noise spectra by use of a cross-correlation method. The radial-velocity curves are fitted by using both a least-squares algorithm and a Nelder-Mead simplex algorithm. We use a Monte Carlo method to compute uncertainties on the orbital elements. The resulting mass functions are used to derive a companion mass distribution by optimising the predicted to the observed cumulative mass-function distributions, after correcting for observational bias. As a result, we derive and update orbital elements for 33 galactic post-AGB binaries, among which 3 are new orbits. The orbital periods of the systems range from 100 to about 3000 days. Over 70 percent (23 out of 33) of our binaries have significant non-zero eccentricities ranging over all periods. Their orbits are non-circular despite the fact that the Roche-lobe radii are smaller than the maximum size of a typical AGB star and tidal circularisation should have been strong when the objects were on the AGB. We derive a distribution of companion masses that is peaked around 1.09 $M_\odot$ with a standard deviation of 0.62 $M_\odot$. The large spread in companion masses highlights the diversity of post-AGB binary systems. Furthermore, we find that only post-AGB stars with high effective temperatures (> 5500 K) in wide orbits are depleted in refractory elements, suggesting that re-accretion of material from a circumbinary disc is an ongoing process. It appears, however, that chemical depletion is inefficient for the closest orbits irrespective of the actual surface temperature.

description: Inverse bicontinuous cubic phases are ubiquitous in lipid-water mixtures and consist of a lipid bilayer forming a cubic minimal surface, thereby dividing space into two cubic networks of water channels. For small hydrocarbon chain lengths, the monolayers can be modeled as parallel surfaces to a minimal midsurface. The bending energy of the cubic phases is determined by the distribution of Gaussian curvature over the minimal midsurfaces which we calculate for seven different structures (G, D, P, I-WP, C(P), S and F-RD). We show that the free-energy densities of the structures G, D and P are considerably lower than those of the other investigated structures due to their narrow distribution of Gaussian curvature. The Bonnet transformation between G, D, and P implies that these phases coexist along a triple line, which also includes an excess water phase. Our model includes thermal membrane undulations. Our qualitative predictions remain unchanged when higher order terms in the curvature energy are included. Calculated phase diagrams agree well with the experimental results for 2:1 lauric acid/dilauroyl phosphatidylcholine and water.

description: Puzzling structures have been observed in the charmonium energy region, namely the $Y(4260)$ and the $Y(4360)$, that cannot be easily accommodated within quark model frameworks. The proximity of nearby dominant hadronic thresholds suggests that they play an important role in the formation of the enhancements. We present results of an unitarized effective Lagrangian model, where mesonic loops, equivalent to coupled-channels, and charmonium vectors $ψ$ interplay to generate line-shapes and poles.

title: Examining the role of comorbidity in socio-economic inequalities in short-term mortality among colon cancer patients in England
Creators: name: Fowler, H
Publisher: name: London School of Hygiene & Tropical Medicine
Year: 2021

description: Colon cancer is one of the most common cancers diagnosed in England. Despite the universal healthcare system, the most deprived groups of colon cancer patients have a poorer prognosis than the more affluent patients, particularly in the short-term following diagnosis. Comorbidity is considered to be a prognostic factor in cancer outcomes. Moreover, the presence of comorbidity tends to be associated with increased levels of socio-economic deprivation. In this thesis I investigated the role that comorbidity plays in socio-economic inequalities in ninety-day mortality after diagnosis with colon cancer. My research used population-based England national cancer registry data linked with Hospital Episode Statistics (HES), National Bowel Cancer Audit (NBOCA) and Route to Diagnosis data of approximately 100,000 patients diagnosed with colon cancer between 2009 and 2013. This research emphasised the increased burden of comorbidity and multiple comorbidity among the most deprived cancer patients. The presence of comorbidity influenced the short-term mortality of the most deprived patients following diagnosis with colon cancer, but stage of diagnosis and the receipt of surgical treatment appeared to be influential factors in socio-economic inequalities in short term mortality. Accounting for time-varying proxy measures of comorbidity severity reduced some of the differences in ninety-day mortality between the most and least deprived patients with pre-existing diabetes, COPD and cardio-vascular conditions, but disparities in mortality still remained, suggesting other factors may be contributing towards inequalities between these groups of patients. The growing prevalence of multimorbidity and the comorbidity burden among cancer patients highlights a need for healthcare systems equipped and resourced for managing multiple chronic conditions simultaneously. Further investigation into healthcare utilisation and access to optimal care may provide insights into opportunities to improve outcomes of deprived patients living with chronic diseases who go on to develop cancer. Mechanisms to be explored include the interplay between deprivation, chronic disease burden, stage at cancer diagnosis and cancer treatment options.

description: The fundamental group $π_1(L)$ of a knot or link $L$ may be used to generate magic states appropriate for performing universal quantum computation and simultaneously for retrieving complete information about the processed quantum states. In this paper, one defines braids whose closure is the $L$ of such a quantum computer model and computes their Seifert surfaces and the corresponding Alexander polynomial. In particular, some $d$-fold coverings of the trefoil knot, with $d=3$, $4$, $6$ or $12$, define appropriate links $L$ and the latter two cases connect to the Dynkin diagrams of $E_6$ and $D_4$, respectively. In this new context, one finds that this correspondence continues with the Kodaira's classification of elliptic singular fibers. The Seifert fibered toroidal manifold $Σ'$, at the boundary of the singular fiber $\tilde {E_8}$, allows possible models of quantum computing.

description: Gravity is one of the fundamental forces of Nature, and it is the dominant force in most astronomical systems. In common with all other phenomena, gravity must obey the principles of special relativity. In particular, gravitational forces must not be transmitted or communicated faster than light. This means that when the gravitational field of an object changes, the changes ripple outwards through space and take a finite time to reach other objects. These ripples are called gravitational radiation or gravitational waves. This article gives a brief introduction to the physics of gravitational radiation, including technical material suitable for non-specialist scientists.

description: The high-capacity DNA analysis of museum samples opens new opportunities, associated with the investigation of extinct species evolution. Here, the complete mitochondrial genome of the presumably extinct bird species, the slender-billed curlew Numenius tenuirostris (Charadriiformes: Scolopacidae) is presented. Our results showed that mitochondrial DNA (mtDNA) is 16,705 base pairs (bp) in length and contain 13 protein-coding genes, two rRNA genes, and 22 tRNA genes. The overall base composition of the genome is 30.8% – A, 29.8% – C, 25.4% – T, 14.0% – G, and without a significant GC bias of 43.7%. Phylogenetic analyses based on the cytochrome B (cytB) gene and the whole mtDNA sequences revealed that N. tenuirostris had a close genetic relationship to Eurasian curlew (N. arquata), Far Eastern curlew (N. madagascariensis), and long-billed curlew – N. americanus. Besides, it reveals that Numenius genus is genetically distant from other Scolopacidae taxons. Together, these results provide a clear genetic perspective into the speciation process among the curlew genus members and points to a clear taxonomic position of N. tenuirostris.

description: We consider perturbations of nonlinear eigenvalue problems driven by a nonhomogeneous differential operator plus an indefinite potential. We consider both sublinear and superlinear perturbations and we determine how the set of positive solutions changes as the real parameter $λ$ varies. We also show that there exists a minimal positive solution $\overline{u}_λ$ and determine the monotonicity and continuity properties of the map $λ\mapsto\overline{u}_λ$. Special attention is given to the particular case of the $p$-Laplacian.

description: In a recent work by Gong and Ueda (arXiv:1710.05289), the classification of (1+1)-dimensional quench dynamics for the ten Altland-Zirnbauer classes is achieved, and entanglement-spectrum crossings of the time-dependent states for the topological classes (AIII, DIII, CII, BDI, and D) are discovered as a consequence of the bulk-edge correspondence. We note that, their classification scheme relies on the limit that the energy spectrum of the post-quench Hamiltonian is flat, because any finite band dispersion leads to the break down of time-reversal and chiral symmetries for the parent Hamiltonian (which are used for the classification). We show that, because of the reduction of symmetry by finite energy dispersion, the gapless entanglement-spectrum crossing in the flat-band limit in classes AIII, DIII, and CII is unstable, and could be gapped without closing the bulk gap. The entanglement-spectrum crossing in classes BDI and D is still stable against energy dispersion. We show that the quench process for classes BDI and D can be understood as a $\mathbb{Z}_2$ fermion parity pump, and the entanglement-spectrum crossing for this case is protected by the conservation of fermion parity.

description: PM2.5-bound polycyclic aromatic hydrocarbons (PAHs) have attracted considerable attention due to their carcinogenicity to humans. As the “copper city” of China, Baiyin has unique natural geographical conditions, but there have been few studies on PM2.5-bound PAHs pollution characteristics. Therefore, the pollution characteristics, sources and health risks of PM2.5-bound PAHs in Baiyin were studied over a one-year period. The average annual PAHs concentration was 67.4 ± 34.7 ng/m3, with the highest PAHs concentration in winter and the lowest in summer. Based on a positive matrix factorization (PMF) model, the main PAHs sources were coal, a mixed source of petroleum volatilization and natural gas and biomass combustion, gasoline exhaust, and diesel exhaust. Spring and winter were dominated by coal combustion, while summer and autumn were dominated by gasoline exhaust. Backward trajectory analysis showed, that the largest pollution contribution came from the local area throughout the year, followed by northern Mongolia in spring, northeastern Xinjiang in summer, and Qinghai in autumn and winter. A human carcinogenic risk assessment based on a health model indicated that PAHs emissions should be controlled in seasons other than summer, especially when there is a risk of ingestion and dermal contact.

description: Lie point symmetries of the one-dimensional gas dynamics equations of a polytropic gas in Lagrangian coordinates are considered. Complete Lie group classification of these equations reduced to a scalar second-order PDE is performed. The classification parameter is the entropy. Noether theorem is applied for constructing conservation laws. The conservation laws can be represented in the gas dynamics variables. For the basic adiabatic case invariant and conservative difference schemes are discussed.
Perioperative Allogenic Red Blood Cell Transfusion: Available Guidance and Audit of Appropriateness in Liver Resection

description: Red blood cells are commonly administered during the perioperative period, however our understanding of available guidance informing transfusion decisions as well as appropriateness of current practice is not well understood. Blood transfusions are associated with post-operative morbidity and possibly worse long-term outcomes. Furthermore, they are a costly and limited resource. They should therefore be used sparingly. The objective of this thesis was to further our understanding of guidance available for administration of intraoperative red blood blood cell transfusion, as well as conduct an audit of the appropriateness of transfusions administered during the perioperative period. This thesis is composed of both a systematic review as well as a retrospective review of a prospectively maintained database. The systematic review of identified 10 guidelines published between 1992-2018 that included indications for intraoperative transfusions. Six provided objective clearly defined criteria for transfusion based on hemoglobin triggers (range 60-100g/L) or hematocrit (<30%); one stated a specific clinical situation for which transfusion would be appropriate (ST changes). The evidence supporting intraoperative recommendations was extrapolated primarily from the non-operative setting. Retrospective review of a single centre revealed 19% of patients underging liver resection were transfused a mean of 2.6 units during the perioperative period. A total of 22% to 63% of transfusions administered during the intraoperative period were considered inappropriate based on the application of three different instruments. In contrast, 38% to 67% of transfusions administered during the postoperative period were considered inappropriate. Patients considered to have been inappropriately transfused during the intraoperative period were at increased risk of developing a major postoperative adverse event (Clavien-Dindograde 3) compared to those who did not receive a transfusion (OR 4.2; 95% CI 1.1-15.6). In conclusion, this thesis demonstrates evidence-based, practitioner oriented, intraoperative transfusion guidance for clinicians is lacking. Furthermore, a significant proportion of patients continue to be exposed to unnecessary transfusion. Further work in this area is warranted to clarify indications for intraoperative transfusion and subsequently minimize the administration of unnecessary transfusion.

description: EPA Storm Water Management Model (EPA-SWMM), developed for the analysis of urban drainage systems, was used in a novel way to simulate the filling phase in intermittent water distribution systems. Firstly, the model was validated against field experimental observations from a filling test in a real water distribution network in Sicily. Then, model results were compared to those obtained by the use of a model based on the theory of the rigid water column, revealing the potential and limitations of the two approaches. The obtained results open new perspectives for the use of EPA-SWMM for the analysis of processes occurring in intermittent water distribution systems.
