description: Researchers found that serum levels of surfactant protein D (SP-D), a protein that protects the lungs against pathogens and regulates inflammation, increased when patients with chronic obstructive pulmonary disease (COPD) experienced acute exacerbations. This supports other studies indicating that the protein could be used to diagnose acute exacerbations of COPD and monitor the progress of the condition.Chronic obstructive pulmonary disease is a progressive lung disease that makes it hard to breathe. It is often accompanied by an acute worsening of the condition, called an exacerbation. However, there is no validated test to diagnose this acute event. Lung function is generally tested using a spirometer, which involves taking a very deep breath then exhaling forcefully into the device. But spirometry is not recommended in unstable patients. Thus, methods are needed to diagnose exacerbations and monitor their progress.The researchers compared SP-D serum levels in 28 healthy individuals with those of 28 patients with stable COPD at Al Assad University Hospital in Damascus, Syria, and another 28 patients experiencing an acute exacerbation of the condition.Serum SP-D levels were significantly increased in all patients with COPD compared to the healthy cohort. They were also significantly higher in the acute compared to the stable COPD patients.The clear difference in the levels between the two groups of COPD patients indicates that serum SP-D could be used as a biomarker to diagnose exacerbation, the researchers say.Airway inflammation that occurs during acute exacerbations of COPD is associated with the elevation of a variety of substances in the circulation. However, they are largely synthesized outside the lungs and their relationship with COPD is unclear. SP-D, on the other hand, is produced by lung cells and is one of the few lung-specific proteins that can be tested in the circulation. This makes it a useful biomarker to track the health status of patients with COPD.The study, published in the Qatar Medical Journal, is the first conducted in Syria on the potential of serum SP-D as a biomarker of COPD exacerbations. The researchers recommend further research to elucidate the precise mechanisms involved in increasing SP-D levels in COPD, which are still unclear. The team hopes to conduct further research to investigate how changes in serum SP-D levels can predict severe exacerbations and how the protein can be used in clinical practice.

description: Quantum communication is a prime space technology application and offers near-term possibilities for long-distance quantum key distribution (QKD) and experimental tests of quantum entanglement. However, there exists considerable developmental risks and subsequent costs and time required to raise the technological readiness level of terrestrial quantum technologies and to adapt them for space operations. The small-space revolution is a promising route by which synergistic advances in miniaturization of both satellite systems and quantum technologies can be combined to leap-frog conventional space systems development. Here, we outline a recent proposal to perform orbit-to-ground transmission of entanglement and QKD using a CubeSat platform deployed from the International Space Station (ISS). This ambitious mission exploits advances in nanosatellite attitude determination and control systems (ADCS), miniaturised target acquisition and tracking sensors, compact and robust sources of single and entangled photons, and high-speed classical communications systems, all to be incorporated within a 10 kg 6 litre mass-volume envelope. The CubeSat Quantum Communications Mission (CQuCoM) would be a pathfinder for advanced nanosatellite payloads and operations, and would establish the basis for a constellation of low-Earth orbit trusted-nodes for QKD service provision.

description: As the quantity of data being depositing into biological databases continues to increase, it becomes ever more vital to develop methods that enable us to understand this data and ensure that the knowledge is correct. It is widely-held that data percolates between different databases, which causes particular concerns for data correctness; if this percolation occurs, incorrect data in one database may eventually affect many others while, conversely, corrections in one database may fail to percolate to others. In this paper, we test this widely-held belief by directly looking for sentence reuse both within and between databases. Further, we investigate patterns of how sentences are reused over time. Finally, we consider the limitations of this form of analysis and the implications that this may have for bioinformatics database design. We show that reuse of annotation is common within many different databases, and that also there is a detectable level of reuse between databases. In addition, we show that there are patterns of reuse that have previously been shown to be associated with percolation errors.

The results obtained for the decays are $τ\to ν_τ (K^{*}(892), K^{*}(1410), K_1(1270))$ in a satisfactory agreement with the experimental data. There are no experimental data for other types of decay. Therefore, the obtained results should be considered as predictions for further experiments.

description: We present a proper motion investigation of a sample of Be star candidates towards the Magellanic Clouds, which has resulted in the identification of separate populations, in the Galactic foreground and in the Magellanic background. Be stars are broadly speaking B-type stars that have shown emission lines in their spectra. In this work, we studied a sample of 2446 and 1019 Be star candidates towards the LMC and SMC respectively, taken from the literature and proposed as possible Be stars due to their variability behaviour in the OGLE-II I band. JHKs magnitudes from the IRSF catalog and proper motions from the SPM4 catalog, were obtained for 1188 and 619 LMC and SMC Be stars candidates, respectively. Color-color and vector-point diagrams were used to identify different populations among the Be star candidates. In the LMC sample, two populations with distinctive infrared colours and kinematics were found, the bluer sample is consistent with being in the LMC and the redder one with belonging to the Milky Way disk. This settles the nature of the redder sample which had been described in previous publications as a possible unknown subclass of stars among the Be candidates in the LMC. In the SMC sample, a similar but less evident result was obtained, since this apparent unknown subclass was not seen in this galaxy. We confirm that in the selection of Be stars by their variability, although generally successful, there is a higher risk of contamination by Milky Way objects towards redder B$-$V and V$-$I colors.

description: In the standard model of non-linear structure formation, a cosmic web of dark-matter dominated filaments connects dark matter halos. In this paper, we stack the weak lensing signal of an ensemble of filaments between groups and clusters of galaxies. Specifically, we detect the weak lensing signal, using CFHTLenS galaxy ellipticities, from stacked filaments between SDSS-III/BOSS luminous red galaxies (LRGs). As a control, we compare the physical LRG pairs with projected LRG pairs that are more widely separated in redshift space. We detect the excess filament mass density in the projected pairs at the $5σ$ level, finding a mass of $(1.6 \pm 0.3) \times 10^{13} M_{\odot}$ for a stacked filament region 7.1 $h^{-1}$ Mpc long and 2.5 $h^{-1}$ Mpc wide. This filament signal is compared with a model based on the three-point galaxy-galaxy-convergence correlation function, as developed in Clampitt, Jain & Takada (2014), yielding reasonable agreement.

Evaluating the New Automatic Method for the Analysis of Absorption Spectra Using Synthetic Spectra

description: We recently presented a new "artificial intelligence" method for the analysis of high-resolution absorption spectra (Bainbridge and Webb, Mon. Not. R. Astron. Soc. 2017, 468,1639-1670). This new method unifies three established numerical methods: a genetic algorithm (GVPFIT); non-linear least-squares optimisation with parameter constraints (VPFIT); and Bayesian Model Averaging (BMA). In this work, we investigate the performance of GVPFIT and BMA over a broad range of velocity structures using synthetic spectra. We found that this new method recovers the velocity structures of the absorption systems and accurately estimates variation in the fine structure constant. Studies such as this one are required to evaluate this new method before it can be applied to the analysis of large sets of absorption spectra. This is the first time that a sample of synthetic spectra has been utilised to investigate the analysis of absorption spectra. Probing the variation of nature's fundamental constants (such as the fine structure constant), through the analysis of absorption spectra, is one of the most direct ways of testing the universality of physical laws. This "artificial intelligence" method provides a way to avoid the main limiting factor, i.e., human interaction, in the analysis of absorption spectra.

description: We give qualitative arguments for the mesoscopic nature of the Sachdev-Yee-Kitaev (SYK) model in the holographic regime with $q^2/N\ll 1$ with $N$ Majorana particles coupled by antisymmetric and random interactions of range $q$. Using a stochastic deformation of the SYK model, we show that its characteristic determinant obeys a viscid Burgers equation with a small spectral viscosity in the opposite regime with $q/N=1/2$, in leading order. The stochastic evolution of the SYK model can be mapped onto that of random matrix theory, with universal Airy oscillations at the edges. A spectral hydrodynamical estimate for the relaxation of the collective modes is made.

Subjects: subject: Strongly Correlated Electrons (cond-mat.str-el)

description: A brief introduction to topological phases is provided, considering several two-band Hamiltonians in one- and two-dimensions. Relevant concepts of the topological insulator theory, such as: Berry phase, Chern number, and the quantum adiabatic theorem, are reviewed in a basic framework, which is meant to be accessible to non-specialists. We discuss the Kitaev chain, SSH, and BHZ models. The role of the electromagnetic interaction in the topological insulator theory is addressed in the light of the Pseudo quantum electrodynamics (PQED). The well known parity anomaly for massless Dirac particle is reviewed in terms of the Chern number. Within the continuum limit, a half-quantized Hall conductivity is obtained. Thereafter, by considering the lattice regularization of the Dirac theory, we show how one may obtain the well known quantum Hall conductivity for a single Dirac cone. The renormalization of the electron energy spectrum, for both small and large coupling regime, is derived. In particular, it is shown that massless Dirac particles may, only in the strong correlated limit, break either chiral or parity symmetries. For graphene, this implies the generation of Landau-like energy levels and the quantum valley Hall effect.

description: À notre époque de mutations sans précédent et mondialisée en rapport au climat, aux biotechnologies, à la mondialisation, etc., nos collectivités ont besoin d’espaces de concertation et d’action en commun. L’histoire des relations internationales est teintée de rapports d’annexion, de colonisation, d’empire, etc. L’ONU incarne de nouvelles tentatives de cohabitation et se veut un espace qui incarne une voix pour tous les États. Ce travail questionne le fonctionnement de l’Assemblée générale et du Conseil de sécurité de l’ONU et veut savoir si, par ces instances, l’ONU satisfait aux conditions de pluralité ; égalité, distinction, indispensables à l’instauration d’un monde commun selon la conception d’Hannah Arendt. Le concept de pluralité dans un horizon de monde commun arendtien permet d’envisager un dialogue et une action en commun sans domination, sans homogénéisation ou universalisme abstraite, etc. Les résultats de ce travail de recherche démontrent qu’il reste du chemin à faire. En effet, l’Assemblée incarne l’ouverture à la diversité d’États qui sont en principe égaux, mais est aux prises avec les intérêts et volontés nationaux. Quant au Conseil de sécurité, celui-ci n’incarne ni l’égalité ni l’ouverture à la diversité et est le terrain de jeux d’intérêts et volontés particuliers. Il nous semble en fin de parcours qu’il serait urgent et nécessaire de réfléchir à la question de la souveraineté des États dans un contexte d’action à plusieurs.

adverse outcome pathway

description: The scientific evidence required to make policy decisions that protect human health can be challenging to organize. Primary research is often silo-ed between different agency repositories, the pace of publication is unflagging and wide-spread interdisciplinary collaboration can be logistically difficult. Since 2012, the Organisation for Economic Co-operation and Development (OECD) adverse outcome pathway (AOP) framework has provided solutions for some of the challenges of supplying relevant and accessible scientific data for evidence-based decision-making. Development of AOPs is guided by a crowd-sourced approach in which progressions of adverse outcomes (AO) are distilled into pathways containing only the essential key events (KEs) and the causal key event relationships (KERs) that connect them. The framework has widely been adopted in the toxicology community and more recently projects have applied it to the radiation safety field. Presently, a collaborative effort aims to further expand the use of AOPs through creating a network linking exposure to the space exposome with resulting human health outcomes. The network contains four adverse non-cancer outcomes for which participants of future long-range space missions will be at risk. The work of this thesis has contributed to the construction of the space-health AOP network by accomplishing two main objectives. The first was the creation of a novel protocol for collecting a weight of evidence (WOE) that included the benefits of scoping review and artificial intelligence (AI) tools for literature screening. The scoping review WOE collection strategy was then deployed for collecting data across all four outcomes in the space-health network. The second objective was to identify KEs and KERs and summarize the WOE linking space exposure to one of the four AOs: vascular remodeling. In addition to summarizing the pathway, we have also highlighted important modulating factors and knowledge gaps in the WOE. This thesis work contributes to the future of the AOP framework by formulating a new development protocol and employing it in a novel regulatory context. Using the new protocol, this thesis has furthered biological understanding of the effects of space exposure on the cardiovascular system by collating mechanistic information across scientific disciplines to identify KEs and KERs in occurrence of vascular remodeling.

description: The optical theorem is an important tool for scattering analysis in acoustics, electromagnetism, and quantum mechanics. We derive an extended version of the optical theorem for the scattering of elastic waves by a spherical inclusion embedded in a linear elastic solid using a vector spherical harmonics representation of the waves. The sphere can be a rigid, empty cavity, elastic, viscoelastic, or layered material. The theorem expresses the extinction cross-section, i.e. the time-averaged power extracted from the incoming beam per its intensity, regarding the partial-wave expansion coefficients of the incident and scattered waves. We establish the optical theorem for a longitudinal spherically focused beam scattered by a sphere. Moreover, we use the optical theorem formalism to obtain the radiation force exerted on an inclusion by an incident plane wave and focused beam. Considering an iron sphere embedded in an aluminum matrix, we compute the scattering and elastic radiation force efficiencies. In addition, the elastic radiation force is obtained on a stainless steel sphere embedded in a tissue-like medium (soft solid). Remarkably, we find a relative difference of up to $98\%$ between our findings and previous lossless liquid models. Regarding some applications, the obtained results have a direct impact on ultrasound-based elastography techniques, ultrasonic nondestructive testing, as well as implantable devices activated by ultrasound.

description: We consider Pauli--Dirac fermion submitted to an inhomogeneous magnetic field. It is showed that the propagator of the neutral Dirac particle with an anomalous magnetic moment in an external linear magnetic field is the causal Green function $S^{c}(x_{b},x_{a})$ of the Pauli--Dirac equation. The corresponding Green function is calculated via path integral method in global projection, giving rise to the exact eigenspinors expressions. The neutral particle creation probability corresponding to our system is analyzed, which is obtained as function of the introduced field $B'$ and the additional spin magnetic moment $μ$.

She can take medication every day for the next three months to clear her illness and then conceive a healthy child in three months’ time or she can take no medication and conceive a child now – but that child will be born with significant health problems. Mary goes ahead and conceives a child now. The child that is born – Mariette – is born with significant health problems and yet, despite a widely held belief that such an act is morally wrong because of what that act has done to Mariette, the non-identity problem presumes to show that this belief is in error: such an act cannot be worse for Mariette, because the alternative for her is not better – she would simply not exist in that alternative; nor does such an act wrong her because her life, although impacted by serious health problems, is still a life worth living – and one does not wrong someone by bringing them into a life worth living. But this means that knowingly conceiving Mariette is not – after all – morally wrong, for we cannot do moral wrong to her without wronging her in the first place. In response to the above case, some philosophers have argued that Mary’s act of conception is still wrong because her act violates an impersonal moral principle – such as a utility-maximizing principle – and this would mean that the act of conception can still be wrong without wronging Mariette. However, establishing that Mary’s act of conception wrongs Mariette is still desirable because most people's intuitive belief about this case is that Mary’s act wrongs her. I argue that, actually, there are some promising person-affecting proposals which show that the act is wrong. I assess three recent proposals; the de-dicto proposal, wherein I develop novel cases to respond to its most challenging objections; as well as the harm and rights-based proposals, wherein I argue that the act of conception is ambiguous and this ambiguity prevents us from appealing to person-affecting proposals. I argue that an alternative understanding of the act is most relevant and this allows person-affecting proposals to overcome their most salient objections. Ultimately, while I do not aim to favour any one person-affecting proposal over another, I aim to have developed several novel arguments that, I argue, allow me to conclude that the prospects for these have not just been underestimated but that there are promising person-affecting proposals that allow us to conclude that Mariette is wronged by the act of conception.

description: We propose non-stationary spectral kernels for Gaussian process regression. We propose to model the spectral density of a non-stationary kernel function as a mixture of input-dependent Gaussian process frequency density surfaces. We solve the generalised Fourier transform with such a model, and present a family of non-stationary and non-monotonic kernels that can learn input-dependent and potentially long-range, non-monotonic covariances between inputs. We derive efficient inference using model whitening and marginalized posterior, and show with case studies that these kernels are necessary when modelling even rather simple time series, image or geospatial data with non-stationary characteristics.

description: This paper intends to present the opportunities emerging for the national economy, out of the financial crisis. In particular the management of those, which arise from the commercial real estate owned property sector, defined by the author as crisis heritage management. On one hand, as real estate property prices are subject of wide fluctuations, the longer possession of such assets can seriously impact the financial condition of the already shattered financial institutions, but on the on other - with the help of professional and proactive management, and the right kind of attitude by all the stakeholders, the heritage left out of the financial collapse, can not only help stabilize the system - bringing liquidity into it, but can also support its healthy corporate governance in the long-term. The properties themselves (business buildings, warehouses, retail-and-office spaces), being an object of optimization of maintenance costs, re-engineering, intensive marketing, as a result of the crisis, can serve as a solid base for number of new and profitable business and investment opportunities, described in the article, as a proof of the healing effect of the financial crisis and the second chance it gives.

description: A Standard Model extension with two Majorana neutrinos can explain the measured neutrino masses and mixings, and also account for the matter-antimatter asymmetry in a region of parameter space that could be testable in future experiments. The testability of the model relies to some extent on its minimality. In this paper we address the possibility that the model might be extended by extra generic new physics which we parametrize in terms of a low-energy effective theory. We consider the effects of the operators of the lowest dimensionality, $d=5$, and evaluate the upper bounds on the coefficients so that the predictions of the minimal model are robust. One of the operators gives a new production mechanism for the heavy neutrinos at LHC via higgs decays. The higgs can decay to a pair of such neutrinos that, being long-lived, leave a powerful signal of two displaced vertices. We estimate the LHC reach to this process.

Doppler Synthetic Aperture Radar Interferometry: A Novel SAR Interferometry for Height Mapping using Ultra-Narrowband Waveforms

description: This paper introduces a new and novel radar interferometry based on Doppler synthetic aperture radar (Doppler-SAR) paradigm. Conventional SAR interferometry relies on wideband transmitted waveforms to obtain high range resolution. Topography of a surface is directly related to the range difference between two antennas configured at different positions. Doppler-SAR is a novel imaging modality that uses ultra-narrowband continuous waves (UNCW). It takes advantage of high resolution Doppler information provided by UNCWs to form high resolution SAR images. We introduced the theory of Doppler-SAR interferometry. We derived interferometric phase model and develop the equations of height mapping. Unlike conventional SAR interferometry, we show that the topography of a scene is related to the difference in Doppler between two antennas configured at different velocities. While the conventional SAR interferometry uses range, Doppler and Doppler due to interferometric phase in height mapping, Doppler-SAR interferometry uses Doppler, Doppler-rate and Doppler-rate due to interferometric phase in height mapping. We demonstrate our theory in numerical simulations. Doppler-SAR interferometry offers the advantages of long-range, robust, environmentally friendly operations; low-power, low-cost, lightweight systems suitable for low-payload platforms, such as micro-satellites; and passive applications using sources of opportunity transmitting UNCW.

description: In the framework of the application of the Boundary Control method to solving the inverse dynamical problems for the one-dimensional Schrödinger and Dirac operators on the half-line and semi-infinite discrete Schrödinger operator, we establish the connections with the method of De Branges: for each of the system we construct the De Branges space and give a natural dynamical interpretation of all its ingredients: the set of function the De Brange space consists of, the scalar product, the reproducing kernel.

description: It is well recognized that looking for new physics at lower energy colliders is a tendency which is complementary to high energy machines such as LHC. Based on large database of BESIII, we may have a unique opportunity to do a good job. In this paper we calculate the branching ratios of semi-leptonic processes $D^+_s \to K^+ e^-e^+$, $D^+_s \to K^+ e^-μ^+$ and leptonic processes $D^0 \to e^-e^+$, $D^0 \to e^-μ^+$ in the frames of $U(1)'$ model, 2HDM and unparticle separately. It is found that both the $U(1)'$ and 2HDM may influence the semi-leptonic decay rates, but only the $U(1)'$ offers substantial contributions to the pure leptonic decays and the resultant branching ratio of $D^0 \to e^-μ^+$ can be as large as $10^{-7}\sim10^{-8}$ which might be observed at the future super $τ$-charm factory.

description: This thesis including publishable works follows the post qualitative turn and employs the culturally alternative medium of the Sikh community kitchen to embark upon the complex entanglements of becoming. I foreground challenges to the praxis of doctoral supervision and highlight the limitations of siloed thinking in traditional research models that confine the expansion of the relational, a less explored facet of research that can enable innovative learning approaches and build safer spaces of knowledge building. The thesis offers the intriguing philosophical and processual dimensions that Langar brings to educational scholarship that challenges the status quo, interrupts hierarchies and negotiates boundaries.

description: We compare the results of the semi-classical (SC) and quantum-mechanical (QM) formalisms for angular-momentum changing transitions in Rydberg atom collisions given by Vrinceanu & Flannery, J. Phys. B 34, L1 (2001), and Vrinceanu, Onofrio & Sadeghpour, ApJ 747, 56 (2012), with those of the SC formalism using a modified Monte Carlo realization. We find that this revised SC formalism agrees well with the QM results. This provides further evidence that the rates derived from the QM treatment are appropriate to be used when modelling recombination through Rydberg cascades, an important process in understanding the state of material in the early universe. The rates for $Δ\ell=\pm1$ derived from the QM formalism diverge when integrated to sufficiently large impact parameter, $b$. Further to the empirical limits to the $b$ integration suggested by Pengelly & Seaton, MNRAS 127, 165 (1964), we suggest that the fundamental issue causing this divergence in the theory is that it does not fully cater for the finite time taken for such distant collisions to complete.

description: Dirac and Weyl fermions appear as quasi-particle excitations in many different condensed-matter systems. They display various quantum transitions which represent unconventional universality classes related to the variants of the Gross-Neveu model. In this work we study the bosonized version of the standard Gross-Neveu model -- the Gross-Neveu-Yukawa theory -- at three-loop order, and compute critical exponents in $4-ε$ dimensions for general number of fermion flavors. Our results fully encompass the previously known two-loop calculations, and agree with the known three-loop results in the purely bosonic limit of the theory. We also find the exponents to satisfy the emergent super-scaling relations in the limit of a single-component fermion, order by order up to three loops. Finally, we apply the computed series for the exponents and their Padé approximants to several phase transitions of current interest: metal-insulator transitions of spin-1/2 and spinless fermions on the honeycomb lattice, emergent supersymmetric surface field theory in topological phases, as well as the disorder-induced quantum transition in Weyl semimetals. Comparison with the results of other analytical and numerical methods is discussed.
