description: We investigate the polarization modulation properties of a variable-delay polarization modulator (VPM). The VPM modulates polarization via a variable separation between a polarizing grid and a parallel mirror. We find that in the limit where the wavelength is much larger than the diameter of the metal wires that comprise the grid, the phase delay derived from the geometric separation between the mirror and the grid is sufficient to characterize the device. However, outside of this range, additional parameters describing the polarizing grid geometry must be included to fully characterize the modulator response. In this paper, we report test results of a VPM at wavelengths of 350 microns and 3 mm. Electromagnetic simulations of wire grid polarizers were performed and are summarized using a simple circuit model that incorporates the loss and polarization properties of the device.

description: We studied the magneto-transport properties of graphene prepared by exfoliation on a III V semiconductor substrate. Tuneability of the carrier density of graphene was achieved by using a doped GaAs substrate as a back-gate. A GaAs/AlAs multilayer, designed to render the exfoliated graphene flakes visible, also provides the required back-gate insulation. Good tuneability of the graphene carrier density is obtained, and the typical Dirac resistance characteristic is observed despite the limited height of the multilayer barrier compared to the usual SiO2 oxide barrier on doped silicon. In a magnetic field weak localization effects as well as the quantum Hall effect of a graphene monolayer are studied.

description: CD147 is a widely expressed matrix metalloproteinase inducer involved in the regulation of cell migration. The high glycosylation and ability to undergo oligomerization have been linked to CD147 function, yet there is limited understanding on the molecular mechanisms behind these processes. The current study demonstrates that the expression of Golgi α1,2-mannosidase I is key to maintaining the cell surface organization of CD147 during cell migration. Using an in vitro model of stratified human corneal epithelial wound healing, we show that CD147 is clustered within lateral plasma membranes at the leading edge of adjacent migrating cells. This localization correlates with a surge in matrix metalloproteinase activity and an increase in the expression of α1,2-mannosidase subtype IC (MAN1C1). Global inhibition of α1,2-mannosidase I activity with deoxymannojirimycin markedly attenuates the glycosylation of CD147 and disrupts its surface distribution at the leading edge, concomitantly reducing the expression of matrix metalloproteinase-9. Likewise, treatment with deoxymannojirimycin or siRNA-mediated knockdown of MAN1C1 impairs the ability of the carbohydrate-binding protein galectin-3 to stimulate CD147 clustering in unwounded cells. We conclude that the mannose-trimming activity of α1,2-mannosidase I coordinates the clustering and compartmentalization of CD147 that follows an epithelial injury.

description: Lyman-break galaxies are now regularly found in the high redshift Universe by searching for the break in the galaxy spectrum caused by the Lyman-limit redshifted into the optical or even near-IR. At lower redshift, this break is covered by the GALEX UV channels and small samples of z ~ 1 LBGs have been presented in the literature. Here we give results from fitting the spectral energy distributions of a small sub-set of low redshift LBGs and demonstrate the advantage of including photometric points derived from HST ACS slitless grism observations. The results show these galaxies to have very young, star forming populations, while still being massive and dusty. LBGs at low and high redshift show remarkable similarities in their properties, indicating that the LBG selection method picks similar galaxies throughout the Universe.

description: The single-mode spin-boson model exhibits behavior not included in the rotating wave approximation (RWA) in the ultra and deep-strong coupling regimes, where counter-rotating contributions become important. We introduce a symmetric rotating wave approximation that treats rotating and counter-rotating terms equally, preserves the invariances of the Hamiltonian with respect to its parameters, and reproduces several qualitative features of the spin-boson spectrum not present in the original rotating wave approximation both off-resonance and at deep strong coupling. The symmetric rotating wave approximation allows for the treatment of certain ultra and deep-strong coupling regimes with similar accuracy and mathematical simplicity as does the RWA in the weak coupling regime. Additionally, we symmetrize the generalized form of the rotating wave approximation to obtain the same qualitative correspondence with the addition of improved quantitative agreement with the exact numerical results. The method is readily extended to higher accuracy if needed. Finally, we introduce the two-photon parity operator for the two-photon Rabi Hamiltonian and obtain its generalized symmetric rotating wave approximation. The existence of this operator reveals a parity symmetry similar to that in the Rabi Hamiltonian as well as another symmetry that is unique to the two-photon case, providing insight into the mathematical structure of the two-photon spectrum, significantly simplifying the numerics, and revealing some interesting dynamical properties.

description: The mechanism by which interferon-gamma (IFN-γ) downregulates trophoblast invasion needs further investigation. Treatment of HTR-8/SVneo cells with IFN-γ led to a decrease in their invasion concomitant with an increased expression of BST2. Silencing of BST2 by siRNA showed a significant increase in their invasion and spreading after treatment with IFN-γ as well as downregulated expression of E-cadherin. Further, STAT1 silencing inhibited the IFN-γ-dependent increase in the expression of BST2 and E-cadherin. Treatment of HTR-8/SVneo cells with IFN-γ led to the activation of AKT, and its inhibition with PI3K inhibitor abrogated IFN-γ-mediated decrease in invasion/spreading and downregulated BST2 and E-cadherin expression. Collectively, IFN-γ decreases the invasion of HTR-8/SVneo cells by STAT1 and AKT activation via increased expression of BST2 and E-cadherin.

Assessment of spatially inhomogeneous intra-organ radiation dose response in salivary glands
Creators: name: Clark, Haley
Publisher: name: University of British Columbia
Year: 2018

description: Cancers treated with radiotherapy must be adequately irradiated to suppress growth at the site of origin. To achieve doses high enough to attain ‘local control’ and inhibit growth of metastases, surrounding normal tissues are selectively co-irradiated. Current clinical practice for head-and-neck cancers involves salivary gland irradiation. Threshold doses that minimize adverse induced toxicities are currently based on whole-organ mean dose. Modern radiation delivery techniques are able to sculpt the dose profile to accommodate sub-organ irradiation, but knowledge of the relative importance of sub-organ structures remains unknown. As tissue-sparing techniques improve, assessment of the normal tissue toxicity risk becomes increasingly important. Loss of salivary function and xerostomia (subjective dry mouth) are common normal tissue toxicities in head-and-neck cancer patients. Radiotherapy-induced dysfunction and xerostomia can drastically reduce oral hygiene and health and may negatively impact the ability to eat, speak, sleep, or swallow. These pervasive toxicities detract from overall quality of life and can be permanent, perpetuating the negative impact. The purpose of this work is to quantify the relative importance of spatial regions within the major salivary glands for late salivary function (i.e., ‘regional effects’). The ultimate aim is to improve knowledge of toxicity risk. Broad regional effects have been noted in rat parotid, and it has recently been claimed that a localized ‘critical region’ has been located in human parotid glands. Furthermore, a morphological dependence on the dose profile has been noted for subjective xerostomia. Clinical trials involving lobe and region sparing are underway, yet comprehensive quantification of the importance of sub-organ structures remains unknown. To this end, the association between radiation dose delivered to regions within the largest salivary glands and measurements of whole-mouth salivary flow is quantified. Independent analysis procedures are developed that are capable of quantifying the relative importance of sub-segments. Evidence is found that sub-segments are inhomogeneously important for maintenance of late salivary flow, with the caudal parotid aspects having greatest importance. An imaging protocol is developed which may help pinpoint specific tissues or functional units residing within these regions.

description: Recent years have seen a sharp growth in Satellite Earth Observation (EO) product applications, such as environment and resource monitoring, emergency management and civilian security leading to an increase in demands on amount, type and quality of remote sensing satellite data and efficient methods for data analysis. While modern Machine Learning (ML) and Artificial Intelligence (AI) algorithms are revolutionizing automatization, speed and quality of data analysis, the use of satellite EO based image products for rapid meteorological and civil security applications is still limited by the bottleneck created by the classical EO data chain, which involves the acquisition, compression, and storage of sensor data on board the satellite, and its transfer to ground for further processing. This introduces long latencies until product delivery to the end user.
 The H2020 EU project EO ALERT (http://eo-alert-h2020.eu) led by DEIMOS, addresses this problem through the development of a next generation EO data processing chain that moves optimised key elements from the ground segment to on board the satellite. Applying optimized ML methods, EO products are generated directly on board the spacecraft.
 The capabilities of the EO ALERT product and its remote sensing data processing chain are demonstrated in an application scenario for meteorological nowcasting and very short range forecasting for early warnings of convective storms Its 3 step approach consists of: Candidate convective cell extraction from satellite imagery, tracking of cell positions and features extracted from infrared channels over time, and the discrimination of convective cells in their different stages of evolution using machine learning classifiers (Gradient Boosting). Training and validation are performed using a specifically created dataset of MSG SEVIRI images and OPERA weather radar network composites corresponding to 205 days between 2016 and 2018 exhibiting extreme convective weather events. The performance is further compared against NWCSAF’s Rapid Developing Thunderstorms (RDT CW) product. Through on board implementation, the system is able to detect convective storm cells and predict their future trajectories, and to send the processed information to ground, within 5 minutes of the observation.

Le nuove frontiere digitali della promulgazione tra potenzialità e zone grigie. Ecclesiastical laws and digital publication. The new frontiers of promulgation in Canon Law ABSTRACT: Technological evolution has redefined spaces and methods of communication also within the Catholic Church. The speed of information exchange, the possibility of reaching a large number of recipients and the absence of costs represent the advanteges of online communication. In addition to encouraging the use of “instruments of social communication” (can. 822 § 1), the Magisterium creates a close connection between these instruments and the mission of proclaiming the Gospel to all peoples. The diffusion of Information and Communication Technology (ICT) involved also the publication of canon laws and it asks about the possibility of using the Internet as a way of promulgating the law. In fact, it can offer potential solutions to the problems raised by the application of can. 8 CIC. The restrictions imposed by the Covid 19 pandemic have further favored the spread of instruments of digital communication. In this perspective, online promulgation could constitute a solution to the limits of canonical legislative governance, allowing the diffusion of legal texts, the relative knowledge and obligation. An intervention by the universal legislator on the matter could offer guarantees about the authenticity of the published document, its unchangeability and the certainty of publication time.

description: We present a study of neutrino-nucleus interactions at the T2K experiment based on the GiBUU transport model. The aim of T2K is to measure $ν_e$ appearance and $θ_{13}$, but it will also be able to do a precise measurement of $ν_μ$ disappearance. The former requires a good understanding of $π^0$ production while the latter is closely connected with a good understanding of quasielastic scattering. For both processes we investigate the influence of nuclear effects and particular final-state interactions on the expected event rates taking into account the T2K detector setup.

Tradition, National Identity, Ethnosymbolism and Discrimination in Hungary: Challenging Fundamental Rights with their Own Weapons Abstract: The ruling coalition in Hungary values tradition, retrieving it in areas that affect both the private sphere of citizens and the public sphere of institutions through political narratives that are implemented by law. Although the "recovered" and interpreted tradition shapes a collective imagination and a normative framework that, according to current language, could be described as extremely conservative, political narratives and normative interventions contribute to social change in an illiberal sense. They intercept widespread malaise and increase discrimination against minorities already at risk. Moving from a unique model of social regulation based on the family, the ruling coalition establishes a link between the latter and the nation, introduces bans on the registration of gender change and the promotion of LGBT contents. Within migration policy, it also constructs the target of migrants and uses Christianity as an ethno-identity component, meanwhile adopting measures that prevent the implementation of Christian values. Moreover, Hungarian narratives, while rejecting the fundamental rights-centered narrative of the liberal tradition, are able to politically "exploit" the expectations it creates among citizens. Following a populist logic, the ruling coalition openly rejects the liberal fundamental rights narrative, but at the same time fully utilizes it.

description: We study the complete class of 5-dimensional asymptotically Schroedinger space-times that can be obtained as the TsT transform of a 5-dimensional asymptotically AdS space-time. Based on this we identify a conformal class of Schroedinger boundaries. We use a Fefferman-Graham type expansion to study the on-shell action for this class of asymptotically Schroedinger space-times and we show that its value is TsT invariant. In the second part we focus on black hole space-times and prove that black hole thermodynamics is also TsT invariant. We use this knowledge to argue that thermal global Schroedinger space-time at finite chemical potential undergoes a Hawking-Page type phase transition.

Function, shock or resources? – Organised Business and the Covid-19 crisis in Germany

description: The paper investigates the role of German business interest groups in the Covid-19 pandemic (March 2020ff.). Taking the perspective of interest group research, we focus on the ‘logic of membership’ and examine the associations’ portfolios and the range of services they offer their members. For this purpose, (a) information, (b) concrete service offers of support to overcome the crisis, and (c) political demands of employers' associations, business associations, and economic chambers (chambers of industry and commerce, chambers of craft) were systematically collected in a comprehensive examination of the associations' websites in spring 2020. The sample includes 136 business associations and economic chambers from all three 'pillars' of the German business interest group system and represents a large part of the German economy (measured by the economic sectors covered accord- ing to NACE Rev. 2). A quantitative overview of the scope and content of Covid-19-specific information, services and political demands is followed by an analysis of the variations within the sample. This is guided by three hypotheses. First, the pillar and organisational structure hypothesis assumes that variances can be explained by the functions and task portfolio in the ‘three pillar model’ of German trade associations. Second, the shock hypothesis assumes that differences in the impact of the Covid-19 pandemic on business sectors and regions (mainly changed consumer behaviour) and the political measures to cope with the crisis (restrictions on economic activity, social distancing, etc.) explain variances across associations. Third, the resource hypothesis assumes that information supply and demands differ according to the capacities of the organisations. Following exchange theory, the study provides new insights into the services business interest groups provide to their members, not only in times of crisis, but also beyond. The hypotheses were only partly confirmed. While differences of the service portfolio of business interest group can partly be explain by the function of the association, shock and resources are of minor importance. It became apparent that chambers of industry and commerce as well as chambers of craft offer a particularly broad service portfolio to their members. Furthermore, it has been shown that the process of de-differentiation between business and employers' associations has also been evident in the Covid-19 crisis.

description: We investigate the phase diagram of an anisotropic ferrimagnet spin-(1/2, 1) in the presence of a non-commuting (transverse) magnetic field. We find a magnetization plateau for the isotropic case while there is no plateau for the anisotropic ferrimagnet. The magnetization plateau can appear only when the Hamiltonian has the U(1) symmetry in the presence of the magnetic field. The anisotropic model is driven by the magnetic field from the Néel phase for low fields to the spin-flop phase for intermediate fields and then to the paramagnetic phase for high fields. We find the quantum critical points and their dependence on the anisotropy of the aforementioned field-induced quantum phase transitions. The spin-flop phase corresponds to the spontaneous breaking of Z2 symmetry. We use the numerical density matrix renormalization group and analytic spin wave theory to find the phase diagram of the model. The energy gap, sublattice magnetization, and total magnetization parallel and perpendicular to the magnetic field are also calculated. The elementary excitation spectrums of the model are obtained via the spin wave theory in the three different regimes depending on the strength of the magnetic field.

description: It is known that the composition of schema mappings, each specified by source-to-target tgds (st-tgds), can be specified by a second-order tgd (SO tgd). We consider the question of what happens when target constraints are allowed. Specifically, we consider the question of specifying the composition of standard schema mappings (those specified by st-tgds, target egds, and a weakly acyclic set of target tgds). We show that SO tgds, even with the assistance of arbitrary source constraints and target constraints, cannot specify in general the composition of two standard schema mappings. Therefore, we introduce source-to-target second-order dependencies (st-SO dependencies), which are similar to SO tgds, but allow equations in the conclusion. We show that st-SO dependencies (along with target egds and target tgds) are sufficient to express the composition of every finite sequence of standard schema mappings, and further, every st-SO dependency specifies such a composition. In addition to this expressive power, we show that st-SO dependencies enjoy other desirable properties. In particular, they have a polynomial-time chase that generates a universal solution. This universal solution can be used to find the certain answers to unions of conjunctive queries in polynomial time. It is easy to show that the composition of an arbitrary number of standard schema mappings is equivalent to the composition of only two standard schema mappings. We show that surprisingly, the analogous result holds also for schema mappings specified by just st-tgds (no target constraints). This is proven by showing that every SO tgd is equivalent to an unnested SO tgd (one where there is no nesting of function symbols). Similarly, we prove unnesting results for st-SO dependencies, with the same types of consequences.

We show existence of our multi-moment maps in many circumstances, including mild topological assumptions on the underlying manifold. Such maps are also shown to exist for all groups whose second and third Lie algebra Betti numbers are zero. We show that these form a special class of solvable Lie groups and provide a structural characterisation. We provide many examples of multi-moment maps for different geometries and use them to describe manifolds with holonomy contained in G_2 preserved by a two-torus symmetry in terms of tri-symplectic geometry of four-manifolds.

We show that, for these three exceptional groups, usage of their principal series, i.e. ascending chains of normal subgroups, greatly facilitates the computations and illuminates the relationship between the groups. As a preparation and testing ground for the usage of principal series, we study first the dihedral-like groups Delta(27) and Delta(54) because both are members of the principal series of the three groups discussed in the paper.

description: Bayesian regression models have been widely studied and adopted in the statistical literature. Many studies consider the development of reliable priors to select the relevant variables and derive accurate posterior predictive distributions. Moreover in the context of small high-dimensional data, where the number of observations is very small with respect to the number of predictors, sparsity is assumed and many parameters can be set to values close to zero without affecting the fit of the model. Aim of this work is to develop a comparative analysis to empirically evaluate the performances of several Bayesian regression approaches in these contexts. In this study we assume that the predictors can be expressed only as binary variables coding the presence or the absence of a particular characteristic of the system. This binary structure is often present in many real studies, in particular in laboratory experimentation and in very high-dimension genome wide association studies.

description: We employ simulations of supersonic super-Alfvenic turbulence decay as a benchmark test problem to assess and compare the performance of nine astrophysical MHD methods actively used to model star formation. The set of nine codes includes: ENZO, FLASH, KT-MHD, LL-MHD, PLUTO, PPML, RAMSES, STAGGER, and ZEUS. We present a comprehensive set of statistical measures designed to quantify the effects of numerical dissipation in these MHD solvers. We compare power spectra for basic fields to determine the effective spectral bandwidth of the methods and rank them based on their relative effective Reynolds numbers. We also compare numerical dissipation for solenoidal and dilatational velocity components to check for possible impacts of the numerics on small-scale density statistics. Finally, we discuss convergence of various characteristics for the turbulence decay test and impacts of various components of numerical schemes on the accuracy of solutions. We show that the best performing codes employ a consistently high order of accuracy for spatial reconstruction of the evolved fields, transverse gradient interpolation, conservation law update step, and Lorentz force computation. The best results are achieved with divergence-free evolution of the magnetic field using the constrained transport method, and using little to no explicit artificial viscosity. Codes which fall short in one or more of these areas are still useful, but they must compensate higher numerical dissipation with higher numerical resolution. This paper is the largest, most comprehensive MHD code comparison on an application-like test problem to date. We hope this work will help developers improve their numerical algorithms while helping users to make informed choices in picking optimal applications for their specific astrophysical problems.

description: The cross-Kerr effect is studied for two pulses propagating in an atomic medium in a tripod configuration, dressed by a strong standing wave coupling beam. Nonlinear phase shifts for both transmitted and reflected beams are calculated taking into account the redistribution of the population among the atomic levels which allows one to study the phase shifts in a wide range of pulse detunings. The influence of other parameters, e.g., the intensity of the control field and the relaxation rates, on the cross-Kerr effect is also examined in detail.

description: We propose a variant of the bootstrap to assess the variability of posterior probabilities arising from Gaussian model-based clustering. The bootstrap variant uses predictions based on out-of-bootstrap-sample observations and then constructs confidence intervals for the posterior probabilities using the percentile method. The methodology outperforms the multivariate Delta method approach when comparing empirical coverage probabilities on simulated data. The proposed and multivariate Delta methods are also illustrated on the well-known Iris data set.

description: Large single crystals of La-doped CaFe2As2 were successfully synthesized by the FeAs self-flux method. The x-ray diffraction patterns suggest high crystalline quality and c-axis orientation. By substitution of trivalent La3+ ions for divalent Ca2+, the resistivity anomaly in the parent compound CaFe2As2 is completely suppressed and a superconducting transition reaches the value of 42.7 K, which is higher than that of about 30 K reported in Saha S. R. et al., arXiv:1105.4798v1. The upper critical field has been determined with the magnetic field along ab-plane and c-axis, yielding an anisotropy of about 3.3.

description: Many new physics models predict the existence of TeV-scale charged gauge boson $W^\prime$ together with Higgs boson(s). We study the $W^\prime WH$ interaction and explore the angular distribution of charged lepton to distinguish $W_R^\prime WH$ from $W_L^\prime WH$ in $pp\to HW\to b \bar b l ν$ process at the LHC. It is found that a new type forward-backward asymmetry($A_{FB}$) relating to the angle between the direction of the charged lepton in $W$ rest frame and that of the reconstructed $W^\prime$ in laboratory frame is useful to investigate the properties of $W^\prime W H$ interaction. We analyze the Standard Model backgrounds and develop a set of cuts to highlight the signal and suppress the backgrounds at LHC. We find that $A_{FB}$ can reach 0.03(-0.07) for $W_R^\prime$($W_L^\prime$) production at $\sqrt{S}=14$ TeV.

description: We obtain Yang-Mills $SU(2)\times G$ gauged supergravity in three dimensions from $SU(2)$ group manifold reduction of (1,0) six dimensional supergravity coupled to an anti-symmetric tensor multiplet and gauge vector multiplets in the adjoint of $G$. The reduced theory is consistently truncated to $N=4$ 3D supergravity coupled to $4(1+\textrm{dim}\, G)$ bosonic and $4(1+\textrm{dim}\, G)$ fermionic propagating degrees of freedom. This is in contrast to the reduction in which there are also massive vector fields. The scalar manifold is $\mathbf{R}\times \frac{SO(3,\, \textrm{dim}\, G)}{SO(3)\times SO(\textrm{dim}\, G)}$, and there is a $SU(2)\times G$ gauge group. We then construct $N=4$ Chern-Simons $(SO(3)\ltimes \mathbf{R}^3)\times (G\ltimes \mathbf{R}^{\textrm{dim}G})$ three dimensional gauged supergravity with scalar manifold $\frac{SO(4,\,1+\textrm{dim}G)}{SO(4)\times SO(1+\textrm{dim}G)}$ and explicitly show that this theory is on-shell equivalent to the Yang-Mills $SO(3)\times G$ gauged supergravity theory obtained from the $SU(2)$ reduction, after integrating out the scalars and gauge fields corresponding to the translational symmetries $\mathbf{R}^3\times \mathbf{R}^{\textrm{dim}\, G}$.
