description: The macrophage activation markers, soluble CD163 (sCD163) and soluble mannose receptor (sMR), are associated with liver disease severity and prognosis. We aimed to investigate macrophage activation reflected by sMR and sCD163 in patients with mild and severe paracetamol (PCM) intoxication and effects of antidote treatment in patients and healthy controls. We measured sMR and sCD163 levels by in-house enzyme-linked immunosorbent assays in two independent prospective cohorts of PCM overdosed patients: 49 patients with early mild PCM overdose from Aarhus University Hospital and 30 patients with severe acute liver injury included at the Royal Infirmary of Edinburgh. Furthermore, we investigated sMR and sCD163 in 14 healthy controls during N-acetylcysteine treatment. Within the mild PCM cohort, patients with elevated alanine transaminase on admission had significantly higher levels of sCD163 compared with patients with normal alanine transaminase (2.92[2.00–5.75] versus 1.29[1.02–1.69] mg/L, p = .009), whereas sMR showed no significant difference. In patients with acute liver injury, both markers were markedly higher compared to the mild PCM cohort (sCD163: 10.73[5.79–14.62] versus 1.34[1.06–1.96], p p

description: We present X-ray and optical properties of the optically confirmed galaxy cluster sample from the 3XMM/SDSS Stripe 82 cluster survey. The sample includes 54 galaxy clusters in the redshift range of 0.05-1.2, with a median redshift of 0.36. We first present the X-ray temperature and luminosity measurements that are used to investigate the X-ray luminosity-temperature relation. The slope and intercept of the relation are consistent with those published in the literature. Then, we investigate the optical properties of the cluster galaxies including their morphological analysis and the galaxy luminosity functions. The morphological content of cluster galaxies is investigated as a function of cluster mass and distance from the cluster center. No strong variation of the fraction of early and late type galaxies with cluster mass is observed. The fraction of early type galaxies as a function of cluster radius varies as expected. The individual galaxy luminosity functions (GLFs) of red sequence galaxies were studied in the five ugriz bands for 48 clusters. The GLFs were then stacked in three mass bins and two redshift bins. Twenty clusters of the present sample are studied for the first time in X-rays, and all are studied for the first time in the optical range. Altogether, our sample appears to have X-ray and optical properties typical of average cluster properties.

The Radical Years of I.L. Peretz

Publisher: name: Columbia University
Year: 2014
Subjects: Jews
East Europeans

description: This dissertation analyzes the works of Yiddish and Hebrew writer Isaac Leib Peretz (1852-1915) during the 1890's. It criticaly engages with the entire range of Peretz's literary output during this period in both languages. It argues that Peretz functioned as a literary agent of the Jewish working class in Eastern Europe which was an ethnic-class fraction that was represented politically by the emerging Jewish Socialist Bund. During this period, Peretz's Yiddish-centric ideology emerged alongside his development as a writer of prose as well as of poetry. Thus he evolved from being a social realist, naturalist, and romantic bilingual politically radical writer into becoming a predominantly Yiddish writer of symbolist drama, folk-tales, and neo-romantic Hasidic stories and poetry during the 20th century. This thesis refutes the long-standing convention in Peretz-scholarship that his interest in new literary styles coinsided with a rejection of revolutionary politics; rather it reflected his ongoing search for new ways of expressing his radicalism.

description: The Lesbian, Gay, Bisexual, Transgender and Queer/Questioning (LGBTQ) Movement has a long history of advocating for equal rights and non-discrimination policies for its members. Their fights, along with the strengthening of the Human Rights discourse in the last years, resulted in a rather fast evolution of Sexual Orientation and Gender Identity (SOGI) in many parts of the world. In this context, Mexico City represents a highly interesting case to be analyzed. In less than 20 years, the local legislation has changed in favor of the LGBTQ population; laws advocating for inclusion and defense of SOGI rights are multiplying, reflecting a deep interest of Mexico City’s government on SOGI issues. However, as important as the LGBTQ movement has been in this phenomenon, it has not been the only element. The evolution of SOGI rights in Mexico City came as a result of the combination of a particular political timing and spatial elements that allowed the City to become more open and liberal than the rest of the country. Mainly, there were four elements that made this development possible: a) the contemporary international Human Rights and SOGI rights trend (deeply linked to Mexico City); b) the characteristics of Mexico City as a big urban area, reshaping sexuality and gender; c) Mexico City’s transition to democracy and the empowerment of a leftwing party in Mexico City; d) a strong tradition of secularism, keeping the Catholic Church outside the creation of laws and court decisions.

description: We present a study of electrical transport properties of $R$Bi$_2$ ($R$ = La, Ce) under hydrostatic pressure up to $\sim$ 2.5 GPa. These measurements are complemented by thermodynamic measurements of the specific heat on CeBi$_2$ at different pressures up to 2.55 GPa. For CeBi$_2$, we find a moderate increase of the antiferromagnetic transition, $T_\text N$, from 3.3 K to 4.4 K by pressures up to 2.55 GPa. Notably, resistance measurements for both CeBi$_2$ and LaBi$_2$ show signatures of superconductivity for pressures above $\sim$ 1.7 GPa. However, the absence of superconducting feature in specific heat measurements for CeBi$_2$ indicates that superconductivity in CeBi$_2$ (and most likely LaBi$_2$ as well) is not bulk and likely originates from traces of Bi flux, either on the surface of the plate-like samples, or trapped inside the sample as laminar inclusions.
The Real Effects of Opacity: Evidence from Tax Avoidance

description: This study provides evidence on a significant real consequence of an opaque financial reporting information environment: increased corporate tax avoidance. Using an international sample of firms, I find that firms with a more opaque information environment, as measured at both the firm and country level, exhibit higher levels of firm-specific tax avoidance. More importantly, additional tests using the adoption of International Financial Reporting Standards (IFRS) as an exogenous shock to the information environment while simultaneously controlling for tax regime changes around the date of IFRS adoption provide direct evidence on the direction of the association, namely that opacity causes tax avoidance. Similarly, the results from tests using the initial enforcement of insider trading laws provide additional support for a directional hypothesis. In support of the firm-level findings, I also find evidence in the aggregate that opacity is associated with countries collecting less corporate tax revenues as a percentage of gross domestic product. In whole, these findings suggest that tax avoidance is a significant real effect of opacity with implications for practitioners, regulators, researchers, and tax-enforcement agencies.

description: Large order asymptotic behaviour of renormalization constants in the minimal subtraction scheme for the $ϕ^4$ $(4-ε)$ theory is discussed. Well-known results of the asymptotic $4-ε$ expansion of critical indices are shown to be far from the large order asymptotic value. A {\em convergent} series for the model $ϕ^4$ $(4-ε)$ is then considered. Radius of convergence of the series for Green functions and for renormalisation group functions is studied. The results of the convergent expansion of critical indices in the $4-ε$ scheme are revalued using the knowledge of large order asymptotics. Specific features of this procedure are discussed.

The Reflective Dimension of Practical Judgment: Kant, Critique, and the Revision of Moral Universals

Subjects: subject: Philosophy
subject: FOS: Philosophy, ethics and religion

description: This dissertation defends a Kantianism that espouses an ethics of principles while emphasizing the role of revising moral principles. It claims that the resources to account for moral revision can be found in Kant’s theory of reflective judgment, the cognitive power required for forming new concepts or principles on the basis of experience. Reflective judgment, on the interpretation elaborated here, involves both the incorporation of new moral particulars into a standing moral conceptual repertoire and the revision of moral universals on the basis of such alterations. The alteration of moral universals and accommodation of recalcitrant particulars are among the operations of what is termed the ‘reflective dimension’ of practical reasoning for Kant, alongside the moral dimension of application of a priori moral principle (most notably, the categorical imperative) typically taken to exhaust Kant’s moral philosophy. Incorporating a reflective dimension into practical deliberation calls for a broader virtue, namely the taking up of a critical stance to one’s principles in general, as well as the cultivation of inventiveness towards the formation of new principles or revision of preexisting ones. Autonomy presupposes heautonomy: the practical requirement of universalizing a given maxim presupposes, first, that one create this maxim, with a critical awareness of its perpetual revisability.

description: By measuring the polarization changes in THz, infrared, and visible radiation over an extended energy range (3-2330 meV), we observe symmetry-breaking in cuprate high temperature superconductors over wide energy, doping, and temperature ranges. We measure the polarization rotation and ellipticity of transmitted radiation though thin films as the sample is rotated. We observe a two-fold rotational symmetry in the Faraday angle, which is associated with linear dichroism (LD) and occurs when electromagnetic radiation polarized along one direction is absorbed more strongly than radiation polarized in the perpendicular direction. Such polarization anisotropies can be generally associated with symmetry breakings. We measure the amplitude of the LD signal and study its temperature, energy, and doping dependence. The LD signal shows a resonant behavior with a peak in the few hundred meV range, which is coincident with the mid-infrared optical feature that has been associated with the formation of the pseudogap state. The strongest LD signal is found in under-doped films, although it is also observed in optimally- and over-doped samples. The LD signal is consistent with nematic charge ordering as well as novel magnetoelectric effects.

description: This work introduces a new space $\T'_*$ of `vertex-smooth' states for use in the loop approach to quantum gravity. Such states provide a natural domain for Euclidean Hamiltonian constraint operators of the type introduced by Thiemann (and using certain ideas of Rovelli and Smolin). In particular, such operators map $\T'_*$ into itself, and so are actual operators in this space. Their commutator can be computed on $\T'_*$ and compared with the classical hypersurface deformation algebra. Although the classical Poisson bracket of Hamiltonian constraints yields an inverse metric times an infinitesimal diffeomorphism generator, and despite the fact that the diffeomorphism generator has a well-defined non-trivial action on $\T'_*$, the commutator of quantum constraints vanishes identically for a large class of proposals.

description: This article proposes a biologically inspired neurocomputational architecture which learns associations between words and referents in different contexts, considering evidence collected from the literature of Psycholinguistics and Neurolinguistics. The multi-layered architecture takes as input raw images of objects (referents) and streams of word's phonemes (labels), builds an adequate representation, recognizes the current context, and associates label with referents incrementally, by employing a Self-Organizing Map which creates new association nodes (prototypes) as required, adjusts the existing prototypes to better represent the input stimuli and removes prototypes that become obsolete/unused. The model takes into account the current context to retrieve the correct meaning of words with multiple meanings. Simulations show that the model can reach up to 78% of word-referent association accuracy in ambiguous situations and approximates well the learning rates of humans as reported by three different authors in five Cross-Situational Word Learning experiments, also displaying similar learning patterns in the different learning conditions.

description: Small interfering RNA (siRNA)-based gene silencing strategy has high potential on suppressing specific molecular targets, involved in cancer progression. However, the lack of an effective nanocarrier system that safely delivers siRNA to its target still limits the clinical applications of siRNA. This study aimed to develop albumin-sericin nanoparticles (Alb-Ser NPs) as a novel siRNA delivery system for laryngeal cancer treatment. Nanoparticle formulations composed of albumin and sericin at different ratios (1:1, 2:1, 1:2 w/w) were synthesized by desolvation method. The nanoparticles were modified with poly-L-lysine (PLL) for siRNA binding and decorated with hyaluronic acid (HA) to target laryngeal cancer cell line, Hep-2. HA/PLL/Alb-Ser NPs were individually loaded with siRNAs for casein kinase 2 (CK2), Absent, Small, or Homeotic-Like (ASH2L), and Cyclin D1 genes, which are overexpressed in Hep-2 cells. Downregulation of genes was confirmed by real-time PCR (RT-PCR). Size, morphological, and thermogravimetric characterizations revealed that Alb-Ser NPs having 2:1 (w/w) ratio are the most optimized formulation. Between 36.8 and 61.3% of siRNA entrapment efficiencies were achieved. HA/PLL-siRNA/Alb-Ser (2:1) NPs-mediated gene silencing resulted in a significant inhibition of cell growth and induction of apoptosis in cells. Our findings showed that HA/PLL/Alb-Ser (2:1) NPs were promising as a siRNA carrier.

description: A transition-metal-free (5+1) cycloaddition of aryl-substituted vinylcyclopropanes (VCPs) and hydrosilanes to afford silacyclohexanes is reported. Catalytic amounts of the trityl cation initiate the reaction by hydride abstraction from the hydrosilane, and further progress of the reaction is maintained by self-regeneration of the silylium ions. The new reaction involves a [1,2] migration of an aryl group, eventually furnishing 4- rather than 3-aryl-substituted silacyclohexane derivatives as major products. Various control experiments and quantum-chemical calculations support a mechanistic picture where a silylium ion intramolecularly stabilized by a cyclopropane ring can either undergo a kinetically favored concerted [1,2] aryl migration/ring expansion or engage in a cyclopropane-to-cyclopropane rearrangement.

description: The nonorthogonality of eigenfunctions over the volume of non-Hermitian systems determines the nature of waves in complex systems. Here, we show in microwave measurements of the transmission matrix that the non-Hermiticity of open random systems leads to enhanced modal excitation and strong correlation between modes. Modal transmission coefficients reach values comparable to the dimensionless conductance which may be much larger than unity. This is accompanied by strong negative correlation between modal speckle patterns ensuring that net transmission is never larger than the incident power.

description: Mitochondrial Complex I (CI) is composed of 44 distinct subunits that are assembled with eight Fe- S clusters and a single flavin mononucleotide. Mitochondria is highly enriched in the flight muscles of Drosophila melanogaster, however the assembly mechanism of Drosophila CI has not been described. We report that the mechanism of CI biogenesis in Drosophila flight muscles proceeds via the formation of ~315- , ~550-, and ~815 kDa CI assembly intermediates. Additionally, we define specific roles for several CI subunits in the assembly process. In particular, we show that dNDUFS5 is required for converting the ~700 kDa transient CI assembly intermediate into the ~815 kDa assembly intermediate, by stabilizing or promoting the incorporation of dNDUFA10 into the complex. Our findings highlight the potential values of Drosophila as a suitable model organism and resource to study the CI biogenesis in vivo, and to address questions relevant to CI biogenesis in humans. CI biogenesis is regulated by transient interactors known as CI assembly factors (CIAFs). To date, about half of CI disorders are attributed to the mutations in the CI subunits and the known CIAFs. The cause for the other half remains to be discovered, warranting the investigation for additional regulators of CI biogenesis such as novel CIAFs. To identify novel regulators, we cataloged interactors of a core subunit, NDUFS3, knocked each one down by RNAi in the Drosophila flight muscle, and analyzed its effect in the stability of CI by blue-native PAGE. We identified the Drosophila Fragile X Mental Retardation protein (dFMRP) to destabilize the holoenzyme of CI and cause it to misassemble. Therefore, we report dFMRP as a novel regulator of CI biogenesis, and demonstrate the utilization of Drosophila as an effective model system to uncover the mysteries of CI biogenesis.

In this paper, a simple excitatory-inhibitory neural pair, which forms the building block of larger networks, is subjected to external stimulation. The response shows transition between various types of dynamics, depending upon the magnitude of the stimulus. Coupling such pairs over a local neighborhood in a two-dimensional plane, the resultant network can achieve a satisfactory segmentation of an image into ``object'' and ``background''. Results for synthetic and and ``real-life'' images are given.

We suggest a classification for these models into two classes, based on the properties of the coupling function, which, in particular, allow, or not, the Reissner-Nordström (RN) BH solution of electrovacuum to solve a given model. Then, a comparative analysis of two illustrative families of solutions, one belonging to each class is performed: $dilatonic$ versus $scalarised$ BHs. By including magnetic charge, that is considering dyons, we show that scalarised BHs can have a smooth extremal limit, unlike purely electric or magnetic solutions. In particular, we study this extremal limit using the entropy function formalism, which provides insight on why both charges are necessary for extremal solutions to exist.

description: Green Stormwater Infrastructure (GSI), which includes elements like green roofs, bioretentions, pervious pavement and cisterns, has proven to be a cost effective alternative that can achieve a wider range of benefits in stormwater management compared to the single-purpose grey/traditional infrastructure (Combined Sewer System or Municipal Separate Storm and Sewer System). However, the implementation of GSI as a replacement or support system for grey infrastructure faces some barriers preventing its adoption by planners/designers and decision makers, in the private as well as in the public sector. While understanding and quantifying the full costs and the benefits of GSI plans are critical for sound decision making and to facilitate its adoption, planners/designers face challenges pertaining to hydrologic calculations (including sizing of Green Stormwater Infrastructure Elements (GSIEs), cost estimation (life cycle costs) and benefit assessment). This thesis presents a proof of concept tool (prototype) that is developed to help planners/designers and different stakeholders involved in conducting a comprehensive GSI planning process. The tool generates GSI alternative solutions (combination and size of GSIEs) that meet the user’s financial and hydrologic objectives. These alternatives are generated to maximize benefits, reduce costs and account for design specifications and multi-functionality of GSI. The prototype has three modules:
An Interface Module (including Input and Output Interfaces) A Process Module for hydrology, cost and benefit calculation and an optimization model for strategy generation.
A Database Module for storing collected data that are used for different process module calculations.
The prototype, which is developed in Ms. Excel, was successfully tested for functionality and usability on a residential development site in Pittsburgh, PA. The prototype required minimal input from the user (site specific data) and generated strategies that double the net annual benefits compared to the plan proposed by the developer. The tool also allowed generation of strategy scenarios that responded to multiple user objectives.

description: The current research used a virtual screening method to study 57 isolated phytochemicals (alkaloids, phytosterols, and flavonoids) against the SARS-CoV-2 main protease (Mpro). The absorption, distribution, metabolism, excretion, and toxicity (ADMET) of the selected compounds were analysed using admetSAR tool while SwissADME and Molinspiration chemoinformatics tools were used to examine the oral bioavailability and drug-likeness properties. Parameters such as physicochemical properties, activity spectra for substances (PASS) prediction, bioactivity, binding mode, and molecular interactions were also analysed. Our results favoured Lupeol (–8.6 kcal/mol), Lupenone (–7.7 kcal/mol), Hesperetin (–7.4 kcal/mol), Apigenin (–7.3 kcal/mol) and Castasterone (–7.3 kcal/mol) as probable inhibitors of SARS-CoV-2. This is because of their good binding affinities, bioactivities, drug-likeness, ADMET properties, PASS properties, oral bioavailability, binding mode and their interactions with the active site of the target receptor compared to Remdesivir and Azithromycin. Therefore, these compounds could be explored towards the development of new therapeutic agents against SARS-CoV-2.

description: During an unguided tour of the Epistemological Forest, we will at least bump into some of the classical questions about knowledge. What is knowledge? How is knowledge acquired? How is knowledge shared? We may also explore some of the more quirky questions. What is the currency for knowledge exchange? What about knowledge banks? Who pays and who collects the dividends? The session will seek to maintain a pragmatic focus in exploring the role and kinds of knowledge and the mechanisms for knowledge exchange in the pursuit of comprehensive community health.

description: We derive a reduction formula for singularly perturbed ordinary differential equations (in the sense of Tikhonov and Fenichel) with a known parameterization of the critical manifold. No a priori assumptions concerning separation of slow and fast variables are made, or necessary.We apply the theoretical results to chemical reaction networks with mass action kinetics admitting slow and fast reactions. For some relevant classes of such systems there exist canonical parameterizations of the variety of stationary points, hence the theory is applicable in a natural manner. In particular we obtain a closed form expression for the reduced system when the fast subsystem admits complex balanced steady states.

description: Recently the construction of the non-abelian effective D-brane action was performed through order $α'{}^3$ including the terms quadratic in the gauginos. This result can be tested by calculating the spectrum in the presence of constant magnetic background fields and comparing it to the string theoretic predictions. This test was already performed for the purely bosonic terms. In this note we extend the test to the fermionic terms. We obtain perfect agreement.

description: This paper is a continuation of our previous work (solv-int/9903001). We obtain two more functional relations for the eigenvalues of the transfer matrices for the $sl(3)$ chiral Potts model at $q^2=-1$. This model, up to a modification of boundary conditions, is equivalent to the three-layer three-dimensional Zamolodchikov model. From these relations we derive the Bethe ansatz equations.

Learning More From Less: Towards Strengthening Weak Supervision for Ad-Hoc Retrieval

description: The limited availability of ground truth relevance labels has been a major impediment to the application of supervised methods to ad-hoc retrieval. As a result, unsupervised scoring methods, such as BM25, remain strong competitors to deep learning techniques which have brought on dramatic improvements in other domains, such as computer vision and natural language processing. Recent works have shown that it is possible to take advantage of the performance of these unsupervised methods to generate training data for learning-to-rank models. The key limitation to this line of work is the size of the training set required to surpass the performance of the original unsupervised method, which can be as large as $10^{13}$ training examples. Building on these insights, we propose two methods to reduce the amount of training data required. The first method takes inspiration from crowdsourcing, and leverages multiple unsupervised rankers to generate soft, or noise-aware, training labels. The second identifies harmful, or mislabeled, training examples and removes them from the training set. We show that our methods allow us to surpass the performance of the unsupervised baseline with far fewer training examples than previous works.
