description: We study the entropy of entanglement of the ground state in a wide family of one-dimensional quantum spin chains whose interaction is of finite range and translation invariant. Such systems can be thought of as generalizations of the XY model. The chain is divided in two parts: one containing the first consecutive L spins; the second the remaining ones. In this setting the entropy of entanglement is the von Neumann entropy of either part. At the core of our computation is the explicit evaluation of the leading order term as L tends to infinity of the determinant of a block-Toeplitz matrix whose symbol belongs to a general class of 2 x 2 matrix functions. The asymptotics of such determinant is computed in terms of multi-dimensional theta-functions associated to a hyperelliptic curve of genus g >= 1, which enter into the solution of a Riemann-Hilbert problem. Phase transitions for thes systems are characterized by the branch points of the hyperelliptic curve approaching the unit circle. In these circumstances the entropy diverges logarithmically. We also recover, as particular cases, the formulae for the entropy discovered by Jin and Korepin (2004) for the XX model and Its, Jin and Korepin (2005,2006) for the XY model.

description: The direct detection of exoplanets with high-contrast instruments can be boosted with high spectral resolution. For integral field spectrographs yielding hyperspectral data, this means that the field of view consists of diffracted starlight spectra and a spatially localized planet. Analysis usually relies on cross-correlation with theoretical spectra. In a purely blind-search context, this supervised strategy can be biased with model mismatch and/or be computationally inefficient. Using an approach that is inspired by the remote-sensing community, we aim to propose an alternative to cross-correlation that is fully data-driven, which decomposes the data into a set of individual spectra and their corresponding spatial distributions. This strategy is called spectral unmixing. We used an orthogonal subspace projection to identify the most distinct spectra in the field of view. Their spatial distribution maps were then obtained by inverting the data. These spectra were then used to break the original hyperspectral images into their corresponding spatial distribution maps via non-negative least squares. The performance of our method was evaluated and compared with a cross-correlation using simulated hyperspectral data with medium resolution from the ELT/HARMONI integral field spectrograph. We show that spectral unmixing effectively leads to a planet detection solely based on spectral dissimilarities at significantly reduced computational cost. The extracted spectrum holds significant signatures of the planet while being not perfectly separated from residual starlight. The sensitivity of the supervised cross-correlation is three to four times higher than with unsupervised spectral unmixing, the gap is biased toward the former because the injected and correlated spectrum match perfectly. The algorithm was furthermore vetted on real data obtained with VLT/SINFONI of the beta Pictoris system.

description: Processing contaminants are chemical substances that have not been intentionally added to edible oils or food. These substances may be present in edible oils and food as a result of the various stages of its production, processing, transport or environmental contamination and may pose a risk to animal and human health. Processing methods include fermentation, smoking, drying, refining and high-temperature cooking. Many foods must be cooked to actually be edible and digestible. It also makes them tastier. However, baking, frying, grilling or barbecuing, either at home or in manufacturing, can have undesired consequences. Besides the loss of some nutrients like vitamins, potentially harmful by-products can develop too. 3-Monochloropropanediol (3-MCPD) is an organic chemical compound, one of the heatand process-induced food contaminants, belonging to a group called chloropropanols and is considered as the most toxic processing contaminant emerging during thermal treatments in refining of edible oils. The aim of this review was to provide an overview of current knowledge regarding 3-MCPD in edible oils for further research, in order to reduce its contents in consumed foodstuffs.

description: We have performed three dimensional nonlinear fluid simulations of electron fluid turbulence at nanoscales in an unmagnetized warm dense plasma in which mode coupling between wave function and electrostatic potential associated with underlying electron plasma oscillations (EPOs) lead to nonlinear cascades in inertial range. While the wave function cascades towards smaller length scales, electrostatic potential follows an inverse cascade. We find from our simulations that quantum diffraction effect associated with a Bohm potential plays a critical role in determining the inertial range turbulent spectrum and the subsequent transport level exhibited by the 3D EPOs.

description: In the search for new spintronic materials with high spin-polarization at room-temperature, we have synthesized an osmium based double perovskite with a Curie-temperature of 725 K. Our combined experimental results confirm the existence of a sizable induced magnetic moment at the Os site, supported by band-structure calculations in agreement with a proposed kinetic energy driven mechanism of ferrimagnetism in these compounds. The intriguing property of Sr2CrOsO6 is that it is at the endpoint of a metal-insulator transition due to 5d band filling, and at the same time ferrimagnetism and high-spin polarization is preserved.

description: The rise of the subscription-based business model has led to a corresponding increase in the number of subscriptions where a customer needs to manage their payments. This management of payments for multiple subscriptions has become a very complicated and insecure task for customers, especially when it comes to renewing payment details when the card is lost, stolen, or expires. In addition, this, mostly manual, process is vulnerable to human error, digital frauds, and data breaches, according to security reports. Thus, in this paper, we propose a novel approach to automate, manage and simplify the Financial Supply Chain involved in the process of updating and managing payments to user subscriptions. This is done by utilising the Hyperledger Sawtooth blockchain framework, that allows a consumer to enter their payment card details in a central digital wallet and link their subscriptions to their cards. The card being updated triggers an event on the blockchain, which allow for the payment details to be updated on subscription systems automatically. The verification tests performed on the prototype of the proposed system shows that its current implementation has been securely achieved.

description: In this paper, we introduce a family of robust estimates for the parametric and nonparametric components under a generalized partially linear model, where the data are modeled by $y_i|(\mathbf{x}_i,t_i)\sim F(\cdot,μ_i)$ with $μ_i=H(η(t_i)+\mathbf{x}_i^{$\mathrm{T}$}β)$, for some known distribution function F and link function H. It is shown that the estimates of $β$ are root-n consistent and asymptotically normal. Through a Monte Carlo study, the performance of these estimators is compared with that of the classical ones.

Stories and storytelling in Alice Munro’s fiction
Creators: name: Somerville, J. Christine
Publisher: name: University of British Columbia
Year: 2010

description: References to stories and storytelling appear throughout Alice Munro's five short story cycles: DANCE OF THE HAPPY SHADES, LIVES OF GIRLS AND WOMEN, SOMETHING I'VE BEEN MEANING TO TELL YOU, WHO DO YOU THINK YOU ARE? and THE. MOONS OF JUPITER. This thesis contends that stories--mentioned briefly or recounted at length--provide counterpoint to experience for Munro's characters. Oral and written stories influence them throughout life, but especially in youth, when they eagerly identify with, and imitate, fictional figures. In LIVES and WHO, storytelling becomes central because their protagonists are a writer and an actress. Occasionally, the narrators in all five works reflect on the difficulty of expressing truth in fiction, but SOMETHING raises this issue repeatedly. By embedding stories within her narratives, Munro imitates the workings of memory; moreover, she draws attention to her narratives as texts rather than glimpses of reality. A feminine perspective on narrative gradually emerges, in which the woman narrator sees her task not as imposing order, but as discovering order that already exists.

description: We argue that the moduli space for the Bagger-Lambert A_4 theory at level k is (R^8 \times R^8)/D_{2k}, where D_{2k} is the dihedral group of order 4k. We conjecture that the theory describes two M2-branes on a Z_{2k} ``M-fold'', in which a geometrical action of Z_{2k} is combined with an action on the branes. For k=1, this arises as the strong coupling limit of two D2-branes on an O2^- orientifold, whose worldvolume theory is the maximally supersymmetric SO(4) gauge theory. Finally, in an appropriate large-k limit we show that one recovers compactified M-theory and the M2-branes reduce to D2-branes.

description: Questo articolo esamina l'intreccio di identità e scrittura nel romanzo nabokoviano The Real Life of Sebastian Knight (1941) da una prospettiva psicoanalitica, seguendo in particolare l'insegnamento di Freud e Lacan sul concetto di desiderio, significante e sublimazione artistica. L'attenzione principale sarà dedicata al rapporto tra i fratellastri, V. (il narratore) e Sebastian. Dopo aver dimostrato che Sebastian Knight ha assunto il ruolo di oggetto del desiderio per chi lo ha conosciuto intimamente (soprattutto V.), muovendo i personaggi secondo ciascun modo d'essere, si passerà al trauma della sua morte e all'elaborazione del lutto da parte del narratore, grazie alla creazione letteraria (la biografia fittizia che leggiamo); il paragrafo conclusivo analizza i cosiddetti 'inganni' del significante, episodi chiave in cui il narratore prende contatto con la verità del desiderio. Dato l'ineludibile interrogativo sulla paternità fittizia della Real Life (se l'autore fosse Sebastian Knight?) e la questione del 'tocco artistico' di V., in questa argomentazione non verranno trascurati gli aspetti metaletterari dell'opera.

This paper examines from a psychoanalytic standpoint the intersection between identity and writing in the novel The Real Life of Sebastian Knight (1941) by Nabokov. In particular, in the wake of Freud’s and Lacan’s teaching, the following contribution will take as interpretative devices the notions of desire, signifier, and the process of sublimation involved in the artistic creation. Main focus of the analysis will be the relationship between the two half-brothers of the novel, V. (the narrator) and Sebastian. First, I will show that Sebastian Knight holds the role of object of desire for the characters who had established a close relationship with him and, in particular, for V.; second, the paper will be devoted to the analysis of the trauma experienced by the char- acters because of V’s death, with a particular focus on the narrator’s grief process through writing (the fictional biography we read in the novel); in the end, I will show evidences of the so-called signifiers fallacy, crucial episodes in which the narrator can experience an insight on the truth of desire. Because of the not negligible question on the fictional paternity of The Real Life and the equally essential matter of V’s ‘stylistic touch’, metaliterary aspects of the novel will also be part of the following reading of the text.

The Protective Effects of Remote Ischaemic Preconditioning on Pressure Overload-Induced Myocardial Remodelling

Publisher: name: University of Leicester
Year: 2021
Subjects: Uncategorized

description: Remote ischaemic conditioning (RIC) is known to protect the myocardium from ischemia/reperfusion injury. More recently, sustained bouts of RIC have shown a potential to attenuate maladaptive remodelling post myocardial infarction (MI) associated with the development of heart failure. The drivers for myocardial remodelling include mechanical stretch and neurohormonal stimulation (e.g. ET-1, Ang-II and alpha-adrenoceptor stimulation) which are also involved in the pressure overload-induced remodelling (e.g. systemic hypertension). So, we have hypothesized that RIC will ameliorate/prevent pathological remodelling from pressure overload.Using cellular models of cyclic stretch- and agonist (e.g. ET-1)- driven adult rat ventricular cardiomyocytes (ARVC) hypertrophy and human cardiac fibroblasts proliferation, I looked for any anti-hypertrophic or anti-fibrotic role of serum collected from healthy human volunteers who have undergone a standard RIC protocol. Cell hypertrophy was assessed by measuring cell size (length width ratio) and proliferation was assessed using BrdU chemiluminescence. Furthermore, I investigated the functional effects of RIC on blood pressure using both in vivo and in vitro models.Unlike normal serum, RIC-serum proved to have strong anti-hypertrophic effects. The cardioprotection afforded by RIC on ET-1-induced hypertrophy was blocked by adenosine and opioid receptor blockers. Both adenosine and endogenous opioids are known to be humoral mediators of RIC protection. Moreover, the antihypertrophic effect RIC serum on stretched ARVCs was also blocked by the use of selective inhibitors of the eNOS/cGMP/sGC/PKG signalling pathway, which is proposed to exert the anti-hypertrophic action of RIC in response to pressure overload. RIC serum, however, did not attenuate fibroblast proliferation induced by either ET-1 or cyclic stretch.RIC resulted in significant, yet transient, drop in blood pressure and shortening of electrocardiographic QT interval. In vitro, RIC-serum caused a sustained vasodilation in a rat mesenteric model of resistance arteries. Unconditioned serum from the same volunteers did not.

description: In the scanning transmission electron microscope, fast-scanning and frame-averaging are two widely used approaches for reducing electron-beam damage and increasing image signal-noise ratio which require no additional specialised hardware. Unfortunately, for scans with short pixel dwell-times (less than 5 $μ$s), line flyback time represents an increasingly wasteful overhead. Although beam exposure during flyback causes damage while yielding no useful information, scan-coil hysteresis means that eliminating it entirely leads to unacceptably distorted images. In this work, we reduce this flyback to an absolute minimum by calibrating and correcting for this hysteresis in postprocessing. Substantial improvements in dose-efficiency can be realised (up to 20 %), while crystallographic and spatial fidelity is maintained for displacement/strain measurement.

description: We present here a review of the fundamental topics of Hartree-Fock theory in Quantum Chemistry. From the molecular Hamiltonian, using and discussing the Born-Oppenheimer approximation, we arrive to the Hartree and Hartree-Fock equations for the electronic problem. Special emphasis is placed in the most relevant mathematical aspects of the theoretical derivation of the final equations, as well as in the results regarding the existence and uniqueness of their solutions. All Hartree-Fock versions with different spin restrictions are systematically extracted from the general case, thus providing a unifying framework. Then, the discretization of the one-electron orbitals space is reviewed and the Roothaan-Hall formalism introduced. This leads to a exposition of the basic underlying concepts related to the construction and selection of Gaussian basis sets, focusing in algorithmic efficiency issues. Finally, we close the review with a section in which the most relevant modern developments (specially those related to the design of linear-scaling methods) are commented and linked to the issues discussed. The whole work is intentionally introductory and rather self-contained, so that it may be useful for non experts that aim to use quantum chemical methods in interdisciplinary applications. Moreover, much material that is found scattered in the literature has been put together here to facilitate comprehension and to serve as a handy reference.

description: The smallness of the 1-3 lepton mixing angle $θ_{13}$ and of the neutrino mass-squared-difference ratio $Δm^2_{12}/Δm^2_{23}$ can be understood as the departure from a common limit where they both vanish. We discuss in general the conditions for realizing the mass degeneracy of a pair of neutrinos and show that the vanishing of a CP violating phase is needed. We find that the discrete quaternion group Q of eight elements is the simplest family symmetry which correlates the smallness of $Δm^2_{12}$ to the value of $θ_{13}$. In such a model we predict $0.12\lesssim \sinθ_{13} \lesssim 0.2$ if the ordering of the neutrino mass spectrum is normal, and $\sinθ_{13}\lesssim 0.12$ if it is inverted.

description: Processing contaminants are chemical substances produced during processing of edible oils and foodstuffs. They also might result from environmental contamination and may pose a risk to animal and human health. Edible oils and foodstuffs processing methods include fermentation, smoking, drying, refining and high-temperature cooking that have been the sources of 3-monochloropropanediol (3-MCPD) and mutagens. Exposure to these processing contaminants could be intentional in terms of food additives and adulterants or unintentional in the case of contaminants such as mycotoxins, pesticides, and metals. The mechanism of action of these chemicals is mainly through DNA damage, which causes mutagenic effects such as chromosomal aberrations, point mutations, frameshift mutation, and cellular transformations, thereby altering the genetic information. In the long run, these changes get translated into various pathologies such as tumor and cancer of various vital organs, thereby posing great threat to the health of consumers. 3-MCPD, mutagens and processing contaminants emerging during thermal processing of edible oils and foodstuffs will be discussed briefly in the current review to provide an overview of current knowledge regarding the critical health risks associated with processing contaminants of edible oils and foodstuffs.
The role of Japan in United States strategic policy for Northeast Asia
Creators: name: Solomon, Russell Keith
Publisher: name: University of British Columbia

description: The role of Japan in any U.S. strategic policy will be decided from the outcome of two debates. These two debates, the Japanese security policy debate and the American strategic policy debate, have been conducted within the leading groups of each country. The debates, both independently and at their points of interaction, illustrate the dynamic nature of the problem of forecasting the kind of security role Japan will perform in any future American strategic policy for the Northeast Asian region. Against a background of a Soviet regional military build-up and increasingly strident American calls for Japan to improve its defence capabilities, the Japanese debate signals a growing consensus for an enhanced security role. However, this trend must be severely qualified by the enduring impact of certain constitutional, political and economic constraints upon security policy-making. The importance that certain leading Japanese groups give to the domestic determinants of policy seems to have been discounted by many leading Americans. Any enhancement of Japan's security role must be accommodated by the Japanese domestic political environment; an environment which retains strong pacifist sentiments. The recent movement towards a military alliance between the two countries needs to be balanced against the continuing relevance that a good proportion of leading Japanese and the Japanese public hold for a minimum defence posture supported by the American security commitment, as embodied in the U.S.-Japan treaty. The American strategic policy debate is concerned with two main policy arguments. The unilateralist/maritime supremacy argument sees the world in essentially bipolar terms and seeks to augment American power so as to be able to overcome a potential enemy, solely through the use of U.S. power. The coalition/defence argument views the world in multipolar terms and believes that deterrence against an enemy should suffice and that this can best be achieved through the utilization and management of allied as well as American forces. The examination of the policy arguments within each of the debates reveals that each is in an insufficiently developed stage to greatly assist our predictions as to Japan's future security role in any American strategic policy. Arguments that Japan is willing to accept specific regional security are easily countered by equally valid ones which foresee no direct security role within any American strategic policy of the near future.

description: Scorzonera comprises 180–190 species and belongs to the subtribe Scorzonerinae. Its circumscription has long been the subject of debate and available molecular phylogenetic analyses affirmed the polyphyly of Scorzonera in its wide sense. We provide a re-evaluation of Scorzonera and other related genera, based on carpological (including anatomical) and extended molecular phylogenetic analyses. We present, for the first time, a comprehensive sampling, including Scorzonera in its widest sense and all other genera recognised in the Scorzonerinae. We conducted phylogenetic analyses using Maximum Parsimony, Maximum Likelihood and Bayesian analyses, based on sequences of the nuclear ribosomal ITS and of two plastid markers (partial rbcL and matK) and Maximum Parsimony for reconstructing the carpological character states at ancestral nodes. Achene characters, especially related to pericarp anatomy, such as general topography of the tissue types, disposition of the mechanical tissue and direction of its fibres, presence or absence of air cavities, provide, in certain cases, support for the phylogenetic lineages revealed. Confirming the polyphyly of Scorzonera, we propose a revised classification of the subtribe, accepting the genera Scorzonera (including four major clades: Scorzonera s. str., S. purpurea, S. albicaulis and Podospermum), Gelasia, Lipschitzia gen. nov. (for the Scorzonera divaricata clade), Pseudopodospermum, Pterachaenia (also including Scorzonera codringtonii), Ramaliella gen. nov. (for the S. polyclada clade) and Takhtajaniantha. A key to the revised genera and a characterisation of the genera and major clades are provided.

description: We study the spectrum of the Fibonacci Hamiltonian and prove upper and lower bounds for its fractal dimension in the large coupling regime. These bounds show that as $λ\to \infty$, $\dim (σ(H_λ)) \cdot \log λ$ converges to an explicit constant ($\approx 0.88137$). We also discuss consequences of these results for the rate of propagation of a wavepacket that evolves according to Schrödinger dynamics generated by the Fibonacci Hamiltonian.

The Role and Regulation of Cortactin in EML4-ALK V3 Non-Small Cell Lung Cancer
Creators: name: Richardson, Emily
Publisher: name: University of Leicester
Year: 2021
Subjects: Uncategorized

description: Lung cancer causes the largest number of cancer-related deaths, largely because it is often diagnosed after metastasis has occurred. Approximately 5% of lung adenocarcinomas are driven by the EML4-ALK oncogenic fusion protein of which variants exist due to differences in the EML4 gene breakpoint. The second most common variant, EML4-ALK V3, is associated with accelerated metastasis, resistance to treatment and poor patient outcome. Experiments undertaken in our laboratory revealed that EML4-ALK V3 leads to a change from epithelial to mesenchymal morphology in cells, as well as increased migration. These properties depend on microtubule-based interaction of EML4-ALK V3 with the NEK9 and NEK7 kinases and coincide with microtubule stabilization.Here, we sought to characterise a potential downstream effector of this pathway, namely the actin regulator cortactin. Cortactin is required for the formation of F-actin branches and is often upregulated or modified in highly invasive tumours. We had identified cortactin as a substrate of NEK6, a highly related kinase to NEK7. This prompted us to hypothesise that activation of NEK7 may contribute to changes in morphology, migration and invasion of cancer cells expressing EML4-ALK V3 through regulation of cortactin.Using a combination of advanced microscopy techniques in 2D and 3D cell culture, as well as in vitro biochemical assays, it was revealed that cortactin is essential for the development of the mesenchymal cell morphology and enhanced migration that occurs downstream of EML4-ALK V3, or constitutively active NEK9 or NEK7 kinases. In addition, it was demonstrated that cortactin is phosphorylated on serine residues in the actin-binding region by NEK7 and that this could alter the association of cortactin with F-actin subtypes. We therefore propose that the EML4(-ALK)-NEK9-NEK7 pathway may represent a novel regulator of microtubule-actin crosstalk, which may be important not only in the migration of cancer cells but also that of normal cells.

description: Yersinia enterocolitica, a zoonotic foodborne pathogen, is able to withstand low temperatures. This psychrotrophic ability allows it to multiply in food stored in refrigerators. However, little is known about the Y. enterocolitica cold response. In this study, isolate-specific behavior at 4°C was demonstrated and the cold response was investigated by examining changes in phenotype, gene expression, and the proteome. Altered expression of cold-responsive genes showed that the ability to survive at low temperature depends on the capacity to acclimate and adapt to cold stress. This cold acclimation at the transcriptional level involves the transient induction and effective repression of cold-shock protein (Csp) genes. Moreover, the resumption of expression of genes encoding other non-Csp is essential during prolonged adaptation. Based on proteomic analyses, the predominant functional categories of cold-responsive proteins are associated with protein synthesis, cell membrane structure, and cell motility. In addition, changes in membrane fluidity and motility were shown to be important in the cold response of Y. enterocolitica. Isolate-specific differences in the transcription of membrane fluidity- and motility-related genes provided evidence to classify strains within a spectrum of cold response. The combination of different approaches has permitted the systematic description of the Y. enterocolitica cold response and gives a better understanding of the physiological processes underlying this phenomenon.

description: Applying broiler litter containing extended-spectrum beta-lactamase (ESBL)–producing Escherichia coli (E. coli) to arable land poses a potential risk for humans to get colonized by contact with contaminated soil or vegetables. Therefore, an inactivation of these bacteria before land application of litter is crucial. We performed 2 short-term litter storage trials (one in summer and winter, respectively), each covering a time span of 5 D to investigate the effectiveness of this method for inactivation of ESBL-producing E. coli in chicken litter. Surface and deep litter samples were taken from a stacked, ESBL-positive chicken litter heap in triplicates in close sampling intervals at the beginning and daily for the last 3 D of the experiments. Samples were analyzed quantitatively and qualitatively for ESBL-producing E. coli, total E. coli, and enterococci. Selected isolates were further characterized by whole-genome sequencing (WGS). In the depth of the heap ESBL-producing E. coli were detected quantitatively until 72 h and qualitatively until the end of the trial in winter. In summer detection was possible quantitatively up to 36 h and qualitatively until 72 h. For surface litter samples a qualitative detection of ESBL-producing E. coli was possible in all samples taken in both trials. In the deep samples a significant decrease in the bacterial counts of over 2 Log10 was observed for total E. coli in the winter and for total E. coli and enterococci in the summer. Genetic differences of the isolates analyzed by WGS did not correlate with survival advantage. In conclusion, short-term storage of chicken litter stacked in heaps is a useful tool for the reduction of bacterial counts including ESBL-producing E. coli. However, incomplete inactivation was observed at the surface of the heap and at low ambient temperatures. Therefore, an extension of the storage period in winter as well as turning of the heap to provide aerobic composting conditions should be considered if working and storage capacities are available on the farms.
