description: We consider symmetric partial exclusion and inclusion processes in a general graph in contact with reservoirs, where we allow both for edge disorder and well-chosen site disorder. We extend the classical dualities to this context and then we derive new orthogonal polynomial dualities. From the classical dualities, we derive the uniqueness of the non-equilibrium steady state and obtain correlation inequalities. Starting from the orthogonal polynomial dualities, we show universal properties of n-point correlation functions in the non-equilibrium steady state for systems with at most two different reservoir parameters, such as a chain with reservoirs at left and right ends.

Patterns in Directionally Solidified Alloys

description: Understanding segregation pattern formation within the solidification structure of directionally solidified alloys is of vital importance for optimising their performance. Segregation patterns are not formed by coincidence, but develop from the constraints imposed by the processing environment and the material chemistry. The most important structure that develops during directional solidification is dendritic. The scale and regularity of a dendritic pattern determines the micro-segregation profile, the propensity for defect formation, and the mechanical properties of the material; thus, is important to study practically.This work contributes to the current literature through the creation of an automatic feature recognition tool, DenMap, which is developed to identify dendritic core position within transverse cross-sections of directionally solidified alloys. DenMap is subsequently advanced with a novel supervised machine learning algorithm, Shape-Limited Primary Spacing (SLPS), that facilitates rapid, accurate, and efficient quantification of cellular and dendritic packing patterns in directionally solidified alloys, formed under different casting conditions. The results reveal the tendency to form hexagonally packed segregation structures under steady state conditions, while all other packing arrangements constitute a metastable state.Using the SLPS algorithm, it has been demonstrated that packing pattern formation and local primary spacing can be employed to deduce dendrite tip growth kinetics. Further, the role of curved isotherms on inducing lateral macro-segregation parallel to a growing solidification front has been revealed. Isotherm curvature results in non-uniform liquid compositional gradients developing parallel to a growing solid interface, leading to the formation of metastable packing, low-angle grain boundaries, and porosity formation within the microstructure. Using crystallographic data from time-of-flight energy-resolved neutron imaging and novel Bragg-dip post processing, it is established that lateral macro-segregation induces mosaicity within single crystals, where fastest growing dendrites demonstrate greater deviation of <001> from the growth axis.

description: We study the hydrodynamic and hydrostatic limits of the one-dimensional open symmetric inclusion process with slow boundary. Depending on the value of the parameter tuning the interaction rate of the bulk of the system with the boundary, we obtain a linear heat equation with either Dirichlet, Robin or Neumann boundary conditions as hydrodynamic equation. In our approach, we combine duality and first-second class particle techniques to reduce the scaling limit of the inclusion process to the limiting behavior of a single, non-interacting, particle.

Void evolution during processing of out-of-autoclave prepreg laminates
Creators: name: Farhang, Leyla
Publisher: name: University of British Columbia
Year: 2015

description: Out-of-Autoclave (OOA) prepreg processing is a promising candidate for replacement of autoclave (AC) processing, which is the current standard for manufacturing primary structural parts in the aerospace industry. However, its success is dependent on the ability to produce high quality parts with low porosity. This thesis develops an understanding of porosity in this process by studying the evolution of the voids during processing. Characterization of voids in partially cured laminates is challenging due to the soft nature of the prepreg matrix. A method for preparation of partially cured samples for optical microscopy and porosity measurement is developed and validated by comparison with results from the ASTM standard density method. It is also shown that thickness can be used to estimate porosity for the no-bleed prepreg system used in this study but that the accuracy is lower than microscopy and density methods. The evolution of voids during different processing cycles and process conditions was studied using the aforementioned optical microscopy on partially cured laminates made of MTM 45-1/5HS carbon/epoxy prepreg. Fiber tow geometry and gas permeability were also measured to determine fibre tow compaction and the gas transport capability throughout the cure process. It is shown that gas transport, fiber bed compaction and resin infiltration govern void evolution during the process. Porosity is governed by multiple chemical and transport phenomena, among which gas transport through vacuum evacuation plays a crucial role. An understanding of gas transport in OOA prepreg processing is developed by examining the time scales for gas transport by Darcy flow and molecular diffusion and comparing those to experimental gas permeability and porosity data. Darcy flow is shown to be the primary means of gas removal during the process. The study shows that the dominant direction of gas transport is dependent on the aspect ratio of the laminate, the prepreg material and the processing history as both in-plane and through-thickness permeability vary throughout the cure cycle. Based on these observations, a simple debulk map that gives the minimum recommended room temperature debulk time for OOA laminates as a function of in-plane and through-thickness dimensions is presented.

description: We consider a two-dimensional nonlinear Schr{ö}dinger equation proposed in Physics to model rotational binary Bose-Einstein condensates. The nonlinearity is a logarithmic modification of the usual cubic nonlinearity. The presence of both the external confining potential and rotating frame makes it difficult to apply standard techniques to directly construct ground states, as we explain in an appendix. The goal of the present paper is to analyze the orbital stability of the set of energy minimizers under mass constraint, according to the relative strength of the confining potential compared to the angular frequency. The main novelty concerns the critical case (lowest Landau Level) where these two effects compensate exactly, and orbital stability is established by using techniques related to magnetic Schr{ö}dinger operators.

description: Today, many companies wanted to shift to a new paradigm replacing the older one prevailed about a century and of course it has changed to a greater extent. Newly introduced systems like pension funds, investment funds, new company owners and knowledge workers represent the new system. The concept of a company follows on changing and it gropes for various business models. Under such business environment, Japanese companies rearrange the strong points cultivated so far and are pressed for presentation of the vision and mission which may be adapted for a new paradigm. A Japanese company never run for M&A again like in the 1980s and make efforts to do their best for the original business, and it has to utilize effectively the opportunity of the company which capital gives and taking care in acquisitions. However, today, the company restructuring shows the vision and mission clearly to which competition between the companies which both stock sharing became thin, the influence of a main bank declined, and poor business performance continued (in the subsidiary company) rather than the independent company system, and include a foreign company is intensifying, and was turned to creation of firm value can be called as the problem of the utmost importance for a present-day manager.
The Genetic Basis of Variation in Response to Chemotherapy and Cancer Chemoprevention Drugs in Saccharomyces cerevisiae

description: There is an inter-individual variation in drug response to anti-cancer agents because it is a complex trait controlled by multiple genes and environmental factors. This thesis explores the genes controlling variation in response to chemotherapy drugs 5-fluorouracil and oxaliplatin as well as cancer chemoprevention agents aspirin, salicylic acid, metformin, disulfiram with copper and curcumin by using quantitative trait loci (QTL) mapping in a model organism Saccharomyces cerevisiae that could potentially identify targets for future human studies. This approach was feasible due to the conservation of genes between these two organisms. A panel of 111 F12 meiotic recombinant segregants from a four-parent S. cerevisiae advanced intercross lines cross previously generated and genotyped by whole genome sequencing was used. Segregant growth under different drug treatments was measured using PHENOS. Subsequently, linkage-based fine QTL mapping was performed to locate associated regions of the genome and identify causative genes. In this study, linkage analysis has mapped hundreds of genetic loci in the yeast genome responsible for the variation in response to the agents tested. Conserved homologs to human genes were identified. Some associated hits are supported by previously reported studies such as the effect of aspirin and metformin on TOR1 (mTOR in humans) and 5-fluorouracil on CDC21 (TYMS in humans) thus validating this screening approach. Identified genes and pathway enrichment revealed mechanisms by which these agents may exhibit their anti-cancer properties. Candidate genes were selected and functionally validated by reciprocal hemizygosity. Furthermore, the yeast gene deletion library was screened to discover additional pathways of aspirin’s response. Detection of genetic variants influencing the differences in drug response could help identify individuals at risk or benefit of using anti-cancer agents. This study could aid the development of biomarkers for drug response, identify targets for genetic testing and validate the repurposing of drugs for cancer prevention.

description: Associated to every closed, embedded submanifold $N$ in a connected Riemannian manifold $M$, there is the distance function $d_N$ which measures the distance of a point in $M$ from $N$. We analyze the square of this function and show that it is Morse-Bott on the complement of the cut locus $\mathrm{Cu}(N)$ of $N$, provided $M$ is complete. Moreover, the gradient flow lines provide a deformation retraction of $M-\mathrm{Cu}(N)$ to $N$. If $M$ is a closed manifold, then we prove that the Thom space of the normal bundle of $N$ is homeomorphic to $M/\mathrm{Cu}(N)$. We also discuss several interesting results which are either applications of these or related observations regarding the theory of cut locus. These results include, but are not limited to, a computation of the local homology of singular matrices, a classification of the homotopy type of the cut locus of a homology sphere inside a sphere, a deformation of the indefinite unitary group $U(p,q)$ to $U(p)\times U(q)$ and a geometric deformation of $GL(n,\mathbb{R})$ to $O(n,\mathbb{R})$ which is different from the Gram-Schmidt retraction.

Scanning tunneling microscopy study of superconducting pairing symmetry : application to LiFeAs
Creators: name: Chi, Shun
Publisher: name: University of British Columbia
Year: 2014

description: Identifying the pairing symmetry is a crucial step towards uncovering the superconducting mechanism. The pairing symmetry and interactions leading to pairing in the iron-based high-temperature superconductors are under debate. In this thesis work, the pairing symmetry of LiFeAs, a stoichiometric superconductor in the iron-based family, is studied by scanning tunneling microscopy. The tunneling conductance spectrum in a defect-free region shows two nodeless superconducting gaps. In addition, a dip-hump above-gap structure was observed, indicating coupling between the superconducting carriers and bosonic modes. Defect bound states were measured for iron-site defects. The bound states are pinned to the gap edge of the small superconducting gap, consistent with theoretical predictions for a sign-changing pairing symmetry. Finally, the observed Bogoliubov quasiparticle interference associated with scattering from defects provides compelling evidence for an s+- pairing symmetry in LiFeAs.

description: Tidal disruption events (TDEs) provide a clue to the properties of a central supermassive black hole (SMBH) and an accretion disk around it, and to the stellar density and velocity distributions in the nuclear star cluster surrounding the SMBH. Deviations of TDE light curves from the standard occurring at a parabolic encounter with the SMBH depends on whether the stellar orbit is hyperbolic or eccentric (Hayasaki et al. 2018) and the penetration factor ($β$, tidal disruption radius to orbital pericenter ratio). We study the orbital parameters of bound and unbound stars being tidally disrupted by comparison of direct $N$-body simulation data with an analytical model. Starting from the classical steady-state Fokker-Planck model of Cohn & Kulsrud (1978), we develop an analytical model of the number density distribution of those stars as a function of orbital eccentricity ($e$) and $β$. To do so fittings of the density and velocity distribution of the nuclear star cluster and of the energy distribution of tidally disrupted stars are required and obtained from $N$-body data. We confirm that most of the stars causing TDEs in a spherical nuclear star cluster originate from the full loss-cone region of phase space, derive analytical boundaries in eccentricity-$β$ space, and find them confirmed by $N$-body data. Since our limiting eccentricities are much smaller than critical eccentricities for full accretion or full escape of stellar debris, we conclude that those stars are only very marginally eccentric or hyperbolic, close to parabolic.

description: We consider composite quantum-dynamical systems that can be partitioned into weakly interacting subsystems, similar to system-bath type situations. Using a factorized wave function ansatz, we mathematically characterize dynamical scale separation.Specifically, we investigate a coupling r{é}gime that is partially flat, i.e., slowly varying with respect to one set of variables, for example, those of the bath. Further, we study the situation where one of the sets of variables is semiclassically scaled and derive a quantum-classical formulation. In both situations, we propose two schemes of dimension reduction: one based on Taylor expansion (collocation) and the other one based on partial averaging (mean-field). We analyze the error for the wave function and for the action of observables, obtaining comparable estimates for both approaches. The present study is the first step towards a general analysis of scale separation in the context of tensorized wavefunction representations.

description: Inspired by the success of WaveNet in multi-subject speech synthesis, we propose a novel neural network based on causal convolutions for multi-subject motion modeling and generation. The network can capture the intrinsic characteristics of the motion of different subjects, such as the influence of skeleton scale variation on motion style. Moreover, after fine-tuning the network using a small motion dataset for a novel skeleton that is not included in the training dataset, it is able to synthesize high-quality motions with a personalized style for the novel skeleton. The experimental results demonstrate that our network can model the intrinsic characteristics of motions well and can be applied to various motion modeling and synthesis tasks.

A 165 Thousand Year Fire History from the Neotropical Andes, Colombia
Creators: name: Currall, Emilia
Publisher: name: University of Leicester
Year: 2022
Subjects: Uncategorized

description: Fire is a global phenomenon with profound and complex ecological, vegetational, climatological and anthropogenic impacts. The natural baseline of a fire regime is a critical foundation on which these impacts can be more fully assessed, however, present knowledge of the natural fire regime remains insufficient and limited empirical studies extend to ages where humans were not present. This leaves outstanding challenges pertaining to the prediction and understanding of past, current and future fire activity. Thus, this thesis presents a ~165 ka charcoal record to reconstruct fire activity and understand its drivers devoid of anthropogenic influence.A ~58m long composite core of lacustrine sediments from Lake Fúquene (5⁰27’N, 73⁰46’W), Colombia contains sediment accumulated over 284 ka and was previously utilised to reconstruct paleoenvironmental and paleoclimatic changes in the Eastern Cordillera. Using this, a record of macrocharcoal (250 μm) particles of the upper 38.7 m of the core was developed and demonstrates the local history of the fire regime from ~189 to ~27 ka. Fire events, their magnitudes and the charcoal accumulation rates were generated from CharAnalysis 1.1 and assisted in establishing four distinct fire regimes. High variability of fire magnitude and frequency occurred from ~189 to ~114 ka and very low fire activity from ~91 to ~114 ka. Charcoal data was related with pollen and climatic records to address climate and vegetation as potential drivers of fire. An association between biomass burning and temperature is determined owing to the temperature sensitive nature of vegetation surrounding Lake Fúquene. Amplified fire activity arises during greater representation of páramo vegetation, signifying páramo increases probability of burning. Conversely, greater Alnus abundance reduces fire activity, attributed to its fire-resistant traits. Two huge spikes of charcoal at ~81.9 and ~82.4 ka are significant yet is attributed to no clear driver.

description: Using quantization techniques, we show that the $δ$-invariant of Fujita-Odaka coincides with the optimal exponent in certain Moser-Trudinger type inequality. Consequently we obtain a uniform Yau-Tian-Donaldson theorem for the existence of twisted Kähler-Einstein metrics with arbitrary polarizations. Our approach mainly uses pluripotential theory, which does not involve Cheeger-Colding-Tian theory or the non-Archimedean language. A new computable criterion for the existence of constant scalar curvature Kähler metrics is also given.

description: In this paper we analyze the large-time behavior of weak solutions to polytropic fluid models possibly including quantum and capillary effects. Formal a priori estimates show that the density of solutions to these systems should disperse with time. Scaling appropriately the system, we prove that, under a reasonable assumption on the decay of energy, the density of weak solutions converges in large times to an unknown profile. In contrast with the isothermal case, we also show that there exists a large variety of asymptotic profiles. We complement the study by providing existence of global-in-time weak solutions satisfying the required decay of energy. As a byproduct of our method, we also obtain results concerning the large-time behavior of solutions to nonlinear Schr{ö}dinger equation, allowing the presence of a semi-classical parameter as well as long range nonlinearities.

description: We study the frequency dependence of the electron self energy and the optical conductivity in a recently developed field theory of the spin density wave quantum phase transition in two dimensional metals. We focus on the interplay between the Fermi surface `hot spots' and the remainder of the `cold' Fermi surface. Scattering of electrons off the fluctuations of the spin density order parameter, ϕ, is strongest at the hot spots; we compute the conductivity due to this scattering in a rainbow approximation. We point out the importance of composite operators, built out of products of the primary electron or $ϕ$ fields: these have important effects also away from the hot spots. The simplest composite operator, ϕ^2, leads to non-Fermi liquid behavior on the entire Fermi surface. We also find an intermediate frequency window in which the cold electrons loose their quasiparticle form due to effectively one-dimensional scattering processes. The latter processes are part of umklapp scattering which leads to singular contributions to the optical conductivity at the lowest frequencies at zero temperature.

Which males and which females are favored by differentially functioning items? examining sources of response pattern heterogeneity within gender groups
Creators: name: Grover, Raman Kumar
Publisher: name: University of British Columbia
Year: 2014

description: In gender differential item functioning (DIF) research it is commonly assumed that all members of a gender group have similar item response patterns and therefore generalizations from group level to subgroup and individual level can accurately be made. However DIF items do not necessarily disadvantage every member of a gender group to the same degree, indicating existence of heterogeneity of item response patterns within gender groups. Previous research has examined heterogeneity in the whole sample but not within the manifest comparison groups such as gender. In this dissertation the impact of heterogeneity within gender groups on gender DIF investigations in reading and math contexts was investigated. Specifically, this dissertation examined: whether DIF results varied when comparing males vs. females, gender x socio-economic status (SES) subgroups and latent classes (LCs) of gender; and whether sources of heterogeneity varied across gender groups in reading and math assessments. DIF analyses were conducted on reading and math achievement data from the Canadian sample of the Programme of International Student Assessment (PISA) 2009. Results indicated considerable heterogeneity within males and females in the reading and math contexts and DIF results were found to vary when heterogeneity was taken into account versus when it was not. The strongest source of gender heterogeneity in reading and math response patterns was reading and math achievement, respectively. However other sources of heterogeneity were found, which varied between gender groups and across reading and math contexts. Unique sources of heterogeneity were found for reading which were not identified for math. This research indicates that males and females are heterogeneous groups with diverse educational, linguistic and socio-cultural backgrounds. By taking into account heterogeneity within gender groups information from DIF results is enhanced, that is, information is revealed on which males or which females are disadvantaged by DIF items. Therefore it is essential that the heterogeneity of gender groups is examined before any inferences about fairness or bias is made. Possible implications of the results and future research directions are discussed.

description: We develop a perturbative expansion scheme for solving general boundary value problems in a broad class of type IIB flux compactifications. The background solution is any conformally Calabi-Yau compactification with imaginary self-dual (ISD) fluxes. Upon expanding in small deviations from the ISD solution, the equations of motion simplify dramatically: we find a simple basis in which the n-th order equations take a triangular form. This structure implies that the system can be solved iteratively whenever the individual, uncoupled equations can be solved. We go on to demonstrate the solution of the system for a general warped Calabi-Yau cone: we present an algorithm that yields an explicit Green's function solution for all the supergravity fields, to any desired order, in terms of the harmonic functions on the base of the cone. Our results provide a systematic procedure for obtaining the corrections to a warped throat geometry induced by attachment to a compact bulk. We also present a simple method for determining the sizes of physical effects mediated through warped geometries.

description: Triptolide, the predominant biologically active component of the Chinese herb Tripterygium wilfordii Hook f., possesses numerous pharmacological activities, including anti-inflammatory, anti-fertility, anti-neoplastic, and immunosuppressive effects. However, toxicity and severe adverse effects, particularly hepatotoxicity, limit the clinical application of triptolide. Licorice root extract contains various bioactive compounds and is potent hepatoprotective. Magnesium isoglycyrrhizinate, a magnesium salt of the 18α-glycyrrhizic acid stereoisomer of glycyrrhizic acid, is used clinically in China to treat chronic viral hepatitis and acute drug-induced liver injury. The aim of this study was to investigate the role of the factor erythroid 2-related factor 2 pathway in the protective effects of LE and MIG against triptolide-induced hepatotoxicity. Hepatotoxicity models were established in L-02 cells and rats using triptolide, and the protective effects of LE and MIG were investigated in vitro and in vivo, respectively. LE and MIG significantly protected against triptolide-induced cytotoxicity. Additionally, triptolide decreased the mRNA and protein levels of Nrf2 and down-regulated Nrf2 target genes, including UGT1A, BSEP, and MRP2, while pretreatment with LE and MIG reversed these effects. Finally, Nrf2-involved antioxidant responses were activated in the presence of LE and MIG.

description: KU Cyg is an eclipsing binary consisting of a F-type star accreting through a large accretion disk from a K5III red giant. Here we present the discovery of a 5-yr dip around 1900 found from its 100 yr DASCH (Digital Access to a Sky Century at Harvard) light curve. It showed a ~0.5 mag slow fading from 1899 to 1903, and brightened back around 1904 on a relatively shorter timescale. The light curve shape of the 1899-1904 fading-brightening event differs from the dust production and dispersion process observed in R Coronae Borealis (RCB) stars, which usually has a faster fading and slower recovery, and for KU Cyg is probably related to the accretion disk surrounding the F star. The slow fading in KU Cyg is probably caused by increases in dust extinction in the disk, and the subsequent quick brightening may be due to the evaporation of dust transported inwards through the disk. The extinction excess which caused the fading may arise from increased mass transfer rate in the system, or from dust clump ejections from the K giant.

description: Multivariate time series data appear often as realizations of non-stationary processes where the covariance matrix or spectral matrix smoothly evolve over time. Most of the current approaches estimate the time-varying spectral properties only retrospectively - that is, after the entire data has been observed. Retrospective estimation is a major limitation in many adaptive control applications where it is important to estimate these properties and detect changes in the system as they happen in real-time. One major obstacle in online estimation is the computational cost due to the high-dimensionality of the parameters. Existing methods such as the Kalman filter or local least squares are feasible. However, they are not always suitable because they provide noisy estimates and can become prohibitively costly as the dimension of the time series increases. In our brain signal application, it is critical to develop a robust method that can estimate, in real-time, the properties of the underlying stochastic process, in particular, the spectral brain connectivity measures. For these reasons we propose a new smooth online parameter estimation approach (SOPE) that has the ability to control for the smoothness of the estimates with a reasonable computational complexity. Consequently, the models are fit in real-time even for high dimensional time series. We demonstrate that our proposed SOPE approach is as good as the Kalman filter in terms of mean-squared error for small dimensions. However, unlike the Kalman filter, the SOPE has lower computational cost and hence scalable for higher dimensions. Finally, we apply the SOPE method to a rat's local field potential data during a hippocampus-dependent sequence-memory task. As demonstrated in the video, the proposed SOPE method is able to capture the dynamics of the connectivity as the rat performs the sequence of non-spatial working memory tasks.

description: Slim-disk models describe accretion flows at high luminosities, while reducing to the standard thin disk form in the low luminosity limit. We have developed a new spectral model, slimbb, within the framework of XSPEC, which describes fully relativistic slim-disk accretion and includes photon ray-tracing that starts from the disk photosphere, rather than the equatorial plane. We demonstrate the features of this model by applying it to RXTE spectra of the persistent black-hole X-ray binary LMC X-3. LMC X-3 has the virtues of exhibiting large intensity variations while maintaining itself in soft spectral states which are well described using accretion-disk models, making it an ideal candidate to test the aptness of slimbb. Our results demonstrate consistency between the low-luminosity (thin-disk) and high luminosity (slim-disk) regimes. We also show that X-ray continuum-fitting in the high accretion rate regime can powerfully test black-hole accretion disk models.

description: We analyze dynamical properties of the logarithmic Schr{ö}dinger equation under a quadratic potential. The sign of the nonlinearity is such that it is known that in the absence of external potential, every solution is dispersive, with a universal asymptotic profile. The introduction of a harmonic potential generates solitary waves, corresponding to generalized Gaussons. We prove that they are orbitally stable, using an inequality related to relative entropy, which may be thought of as dual to the classical logarithmic Sobolev inequality. In the case of a partial confinement, we show a universal dispersive behavior for suitable marginals. For repulsive harmonic potentials, the dispersive rate is dictated by the potential, and no universal behavior must be expected.

description: For every integer $r\ge3$ and every $\eps>0$ we construct a graph with maximum degree $r-1$ whose circular total chromatic number is in the interval $(r,r+\eps)$. This proves that (i) every integer $r\ge3$ is an accumulation point of the set of circular total chromatic numbers of graphs, and (ii) for every $Δ\ge2$, the set of circular total chromatic numbers of graphs with maximum degree $Δ$ is infinite. All these results hold for the set of circular total chromatic numbers of bipartite graphs as well.

description: It is shown that the Bellman function method can be applied to study the $L^p$-norms of general operators on martingales, i.e., of operators that are not necessarily martingale transforms. Informally, we provide a single Bellman-type function that "encodes" the $L^p$-boundedness of "almost all" operators from Gundy's extrapolation theorem. As examples of such operators, we consider the Haar transforms and the operator whose $L^p$-boundedness underlies Rubio de Francia's inequality for the Walsh system.

description: Extension of very long baseline interferometry (VLBI) to observing wavelengths shorter than 1.3mm provides exceptional angular resolution (~20 micro arcsec) and access to new spectral regimes for the study of astrophysical phenomena. To maintain phase coherence across a global VLBI array at these wavelengths requires that ultrastable frequency references be used for the heterodyne receivers at all participating telescopes. Hydrogen masers have traditionally been used as VLBI references, but atmospheric turbulence typically limits (sub) millimeter VLBI coherence times to ~1-30 s. Cryogenic Sapphire Oscillators (CSO) have better stability than Hydrogen masers on these time scale and are potential alternatives to masers as VLBI references. Here, We describe the design, implementation and tests of a system to produce a 10 MHz VLBI frequency standard from the microwave (11.2 GHz) output of a CSO. To improve long-term stability of the new reference, the CSO was locked to the timing signal from the Global Positioning System satellites and corrected for the oscillator aging. The long-term performance of the CSO was measured by comparison against a hydrogen maser in the same laboratory. The superb short-term performance, along with the improved long-term performance achieved by conditioning, makes the CSO a suitable reference for VLBI at wavelengths less than 1.3mm.

description: This article seeks to present an overview of First World War literature across many of the combatant nations from the outbreak of the conflict up to the beginning of the Second World War. Taking a comparative approach, it examines factors that prompted writers to engage with the conflict, as well as the ultimate legacy of war literature. In particular, it focuses upon problems of language and interpretation faced by those who wrote about the war, and the differences of experience between civilians and soldier-writers. Furthermore, it details the products of the interwar ‘war books boom’, and some of the literary and historical responses to these.

description: Nonlinear metamaterials (NLMMs) have been predicted to support new and exciting domains in the manipulation of light, including novel phase matching schemes for wave mixing. Most notable is the so-called nonlinear-optical mirror, in which a nonlinear negative-index medium emits the generated frequency towards the source of the pump. For the first time, we experimentally demonstrate the nonlinear-optical mirror effect in a bulk negative-index NLMM, along with two other novel phase matching configurations, utilizing periodic poling to switch between the three phase matching domains.

description: An Indian Expeditionary Force was sent to France and Belgium in September 1914 and held part of the frontline against the German army until October 1915, sustaining 22,000 casualties. Although its performance came under criticism from British commanders and later historians, the Force contributed in a crucial way to stemming the German advance, and remains a testimony to the way Indian human resources were mobilized in the service of the British Empire during both world wars.

description: We consider the Schr{ö}dinger equation with a nondispersive logarithmic nonlinearity and a repulsive harmonic potential. For a suitable range of the coefficients, there exist two positive stationary solutions, each one generating a continuous family of solitary waves. These solutions are Gaussian, and turn out to be orbitally unstable. We also discuss the notion of ground state in this setting: for any natural definition, the set of ground states is empty.
