description: Abstract: The metalloenzyme [Fe]-hydrogenase (Hmd) is present in methanogenic archaea and catalyzes the activation of dihydrogen (H₂) and hydride (H⁻) transfer to its pterin-like substrate, methenyl-tetrahydromethanopterin (methenyl-H₄MPT⁺) to form methylene-tetrahydromethanopterin (methylene-H₄MPT). This reaction represents one of the steps in the assimilation of CO₂ to generate CH₄ performed by methanogens in Nature. The active site of [Fe]-hydrogenase is comprised of a pyridone cofactor-ligated mononuclear, redox-inactive ferrous site, cysteine ligation, and a cis dicarbonyl motif and has inspired synthetic model complexes as it: (i) features a highly asymmetric primary coordination sphere (ii) contains a unique, highly-substituted acylpyridone organic metal-binding cofactor (iii) contains the first stable organometallic metal-carbon [sigma] bond (Fe-C [subscript acyl]) that persists throughout catalysis in biology. Mechanistic intermediates of Hmd catalysis have been difficult to observe, and functional synthetic model systems that provide insight into the mechanistic understanding of [Fe]-hydrogenase are very limited. This work describes the utility of an anthracene molecular scaffold in the design of model complexes of [Fe]-hydrogenase to encourage precise, directed metal coordination motifs, to impart stability, and to enable functional reactivity studies. An anthracene-scaffolded carbamoyl thiolate complex was synthesized, characterized, and was demonstrated to activate to H₂ and perform the biomimetic hydride transfer reaction to a model substrate upon addition of exogenous base. Another anthracene-scaffolded acyl thioether complex was synthesized and characterized, and treatment with exogenous base resulted in deprotonation of a methylene proton of the acyl moiety. The deprotonated complex was structurally characterized and demonstrated to react with H₂; however, H₂ activation resulted in reduction of the metal center and extrusion of iron from the ligand initiated by iron hydride formation. The design and syntheses of an anthracene-scaffolded [Fe]-hydrogenase model complex for incorporation into a beta-lactoglobulin protein host are described, along with preliminary circular dichroism and fluorescence spectroscopy studies of ligand integration.

description: The ~9.5 kilobase HIV-1 genome contains RNA sequences and structures that control many aspects of viral replication, including transcription, splicing, nuclear export, translation, packaging and reverse transcription. Nonetheless, chemical probing and other approaches suggest that the HIV-1 genome may contain many more RNA secondary structures of unknown importance and function. To determine whether there are additional, undiscovered cis-acting RNA elements in the HIV-1 genome that are important for viral replication, we undertook a global silent mutagenesis experiment. Sixteen mutant proviruses containing clusters of ~50 to ~200 synonymous mutations covering nearly the entire HIV-1 protein coding sequence were designed and synthesized. Analyses of these mutant viruses resulted in their division into three phenotypic groups. Group 1 mutants exhibited near wild-type replication, Group 2 mutants exhibited replication defects accompanied by perturbed RNA splicing, and Group 3 mutants had replication defects in the absence of obvious splicing perturbation. The three phenotypes were caused by mutations that exhibited a clear regional bias in their distribution along the viral genome, and those that caused replication defects all caused reductions in the level of unspliced RNA. We characterized in detail the underlying defects for Group 2 mutants. Second-site revertants that enabled viral replication could be derived for Group 2 mutants, and generally contained point mutations that reduced the utilization of proximal splice sites. Mapping of the changes responsible for splicing perturbations in Group 2 viruses revealed the presence of several RNA sequences that apparently suppressed the use of cryptic or canonical splice sites. Some sequences that affected splicing were diffusely distributed, while others could be mapped to discrete elements, proximal or distal to the affected splice site(s). Overall, our data indicate complex negative regulation of HIV-1 splicing by RNA elements in various regions of the HIV-1 genome that enable balanced splicing and viral replication. © 2018 Takata et al.

description: A 46-year-old man experienced seizures a few hours after starting treatment with transdermal fentanyl for chronic pain. At the emergency room, his physical and neurological examinations were unremarkable. The lab work-up and brain computerized axial tomography were showed no abnormalities. Since the preliminary diagnosis was pseudoseizures, he was referred to the emergency psychiatrist, who considered that there was no context for a conversion disorder and double-checked the list of medication. He raised the hypothesis of pseudoseizures caused by fentanyl. A quick literature search revealed only a few reported cases of fentanyl-induced seizures, although in the context of general anaesthesia. The patient improved after treatment with intravenous valproic acid and discharged. He was observed twice at the outpatient clinic, within three months, and remained asymptomatic. The present case reminds clinicians that fentanyl can cause epileptiform-like seizures. Moreover, when physicians in general and psychiatrists, in particular, evaluate the diagnosis of conversion disorder, they should consider the hypothesis of symptoms secondary to the effect of substances or medications.

description: We derive the explicit expression for the four-point correlation function of stress-energy tensors in four-dimensional N=4 superconformal theory. We show that it has a remarkably simple and suggestive form allowing us to predict a large class of four-point correlation functions involving the stress-energy tensor and other conserved currents. We then apply the obtained results on the correlation functions to computing the energy-energy correlations, which measure the flow of energy in the final states created from the vacuum by a source. We demonstrate that they are given by a universal function independent of the choice of the source. Our analysis relies only on N=4 superconformal symmetry and does not use the dynamics of the theory.

Particle-Number-Conserving Bogoliubov Approximation for Bose-Einstein Condensates Using Extended Catalytic States

Subjects: subject: Quantum Gases (cond-mat.quant-gas)

description: We encode the many-body wavefunction of a Bose-Einstein condensate (BEC) in the $N$-particle sector of an extended catalytic state. This catalytic state is a coherent state for the condensate mode and an arbitrary state for the modes orthogonal to the condensate mode. Going to a time-dependent interaction picture where the state of the condensate mode is displaced to the vacuum, we can organize the effective Hamiltonian by powers of ${N}^{-1/2}$. Requiring the terms of order ${N}^{1/2}$ to vanish gives the Gross-Pitaevskii equation. Going to the next order, $N^0$, we derive equations for the number-conserving Bogoliubov approximation, first given by Castin and Dum [Phys. Rev. A $\textbf{57}$, 3008 (1998)]. In contrast to other approaches, ours is well suited to calculating the state evolution in the Schrödinger picture; moreover, it is straightforward to generalize our method to multi-component BECs and to higher-order corrections.

We establish formulas for the long-time asymptotics of the solution by performing a Deift-Zhou steepest descent analysis of a regularized version of this Riemann-Hilbert problem.

description: Second semester University: University of Graz.
description: The main issue addressed by this thesis concerns the methodological value of economic analysis for human rights research. It inquires if law and economics can be a useful analytical tool to better understand cases that involve value conflicts, and which impose selective measures. Because human rights research adopts a deontological approach as its philosophical background, this work tries to reconcile this trend with elements of a consequentialist approach present in the economic reasoning. In the last chapter, the general methodological analysis is placed in the context of the case law of the European Court of Human Rights on the right to freedom of expression. The economic theory can explain differences in the protection of certain kinds of speech and certain categories of persons by focusing on speech’s external effects. The conclusions reached through the application of economic tools, on how far should the European supervision go, are confronted the options followed by the Court. The analysis shows that the economic theory applied to this right has an explanatory role of many of the decisions of the Court that often reaches similar conclusions by following a different reasoning. However, regarding many of the problems raised by free speech, the Court still has a hesitant case law. Economic analysis can serve an important normative purpose by suggesting the way in which the exceptions laid in Article 10 should be interpreted
Abstract_Framing the Trump administration’s “zero tolerance” policy- A quantitative content analysis of news stories and visuals in U.S. news websites.pdf

description: A quantitative content analysis was employed to study how websites of newspapers (The New York Times, Washington Post, The Wall Street Journal) and cable news (CNN, MSNBC, Fox News) framed the Trump administration’s “zero tolerance” policy in stories (N=477) and visuals (N=501). Overall, Attribution of responsibility was the most used frame and the news content was much more thematic then episodic, with the exception of the Human interest frame. Looking at the individual news websites, The New York Times and the Washington Post used more frequently the Morality frame, while CNN and MSNBC had more Human interest stories and The Wall Street Journal focus more on the Economic frame. Crime was prominent only on Fox News. The visuals predominantly focused on immigrants in shelters and children stopped at the border, and they portrayed more negative than positive emotions. Fox News was the only news outlet to publish images of immigrants trying to force the border, and to release more visuals of men alone. CNN and MSNBC used more frequently images of immigrants looking directly at the camera. Surprisingly, The New York Times, whose stories criticized the policy, published the lowest number of images portraying children behind bars.

This novel experimental technique, in the field of dark energy research, exploits both the chameleon coupling to matter ($β_{\rm m}$) and to photons ($β_γ$) via the Primakoff effect. By reducing the X-ray detection energy threshold used for axions from 1$\,$keV to 400$\,$eV CAST became sensitive to the converted solar chameleon spectrum which peaks around 600$\,$eV. Even though we have not observed any excess above background, we can provide a 95% C.L. limit for the coupling strength of chameleons to photons of $β_γ\!\lesssim\!10^{11}$ for $1

description: Second semester University: Adam Mickiewicz University, Poznan.
description: This study examines hactivism and cyberterrorism, how OSCE participating states have responded to these phenomena and have these responses respected user’s human rights, especially the right to freedom of expression. Right to Freedom of Expression is a fundamental human right in international human rights law. This right includes the freedom to hold opinions without interference and seek, receive and impart information and ideas trough any media and regardless of frontiers. Hacktivism is nonviolent use of illegal or legally ambiguous digital tools in pursuit of political ends. Cyberterrorism consists of politically motivated illegal attacks against information, computer systems, programs and data resulting in violence against noncombatant targets. OSCE is the world’s largest regional security organisation of 56 states. The organisation has a comprehensive approach to security, including politico-military, economic, environmental and human aspects. OSCE participating states have different kinds of approaches to respond to the acts of hacktivism and cyberterrorism. This study is based on literature review on relevant topics. It will not go deep into technical or legal details, but aims to give an overview of the situation in the OSCE participating states. Main focus for the legal instruments is on the United Nations and Council of Europe standards adopted by OSCE. A short case study on Poland is included. Software piratism, copyright issues and cyber war attacks conducted by states are outside the scope of this study. The study found out, that hacktivists and cyberterrorists share many tools and methods, but the main differences between these phenomena are intended use of violent methods and level of concern for the welfare of the other users. However, academia, governments and mass media often place hacktivism and cyberterrorism in the same category. OSCE states have responded to hacktivism and cyberterrorism with domestic legislation and institutions, international conventions, technical measures and specialized institutions. More focused and human rights respecting co-operation is needed. Current, imposed content filtering and blocking methods may violate users’ right to freedom of expression.

description: We consider wave equations with time-independent coefficients that have $C^{1,1}$ regularity in space. We show that, for nontrivial ranges of $p$ and $s$, the standard inhomogeneous initial value problem for the wave equation is well posed in Sobolev spaces $\mathcal{H}^{s,p}_{FIO}(\mathbb{R}^{n})$ over the Hardy spaces $\mathcal{H}^{p}_{FIO}(\mathbb{R}^{n})$ for Fourier integral operators introduced recently by the authors and Portal, following work of Smith. In spatial dimensions $n = 2$ and $n=3$, this includes the full range $1 < p < \infty$. As a corollary, we obtain the optimal fixed-time $L^{p}$ regularity for such equations, generalizing work of Seeger, Sogge and Stein in the case of smooth coefficients.

description: In analogy with the Barbasch-Vogan duality for real reductive linear groups, we introduce a duality notion useful for the representation theory of the real metaplectic groups. This is a map on the set of nilpotent orbits in a complex symplectic Lie algebra, whose range consists of the so-called metaplectic special nilpotent orbits. We relate this duality notion with the theory of primitive ideals and extend the notion of special unipotent representations to the real metaplectic groups. We also interpret the duality map in terms of double cells of Weyl group representations.

description: We show that the approaches to integrable systems via 4d Chern-Simons theory and via symmetry reductions of the anti-self-dual Yang-Mills equations are closely related, at least classically. Following a suggestion of Kevin Costello, we start from holomorphic Chern-Simons theory on twistor space, defined with the help of a meromorphic (3,0)-form $Ω$. If $Ω$ is nowhere vanishing, it descends to a theory on 4d space-time with classical equations of motion equivalent to the anti-self-dual Yang-Mills equations. Examples include a 4d analogue of the Wess-Zumino-Witten model and a theory of a Lie algebra valued scalar with a cubic two derivative interaction. Under symmetry reduction, these yield actions for 2d integrable systems. On the other hand, performing the symmetry reduction directly on twistor space reduces holomorphic Chern-Simons theory to the 4d Chern-Simons theory with disorder defects studied by Costello & Yamazaki. Finally we show that a similar reduction by a single translation leads to a 5d partially holomorphic Chern-Simons theory describing the Bogomolny equations.

description: Though quantum algorithm acts as an important role in quantum computation science, not only for providing a great vision for solving classically unsolvable problems, but also due to the fact that it gives a potential way of understanding quantum physics, the origin of the power of quantum algorithm is still an open question. Non-classical correlation is regarded as the most possible answer for the open question. However we experimentally realize a quantum speed-up algorithm on four-level system with linear optical elements and prove that even a single qudit is enough for designing an oracle-based algorithm which can solve a model problem twice faster than any classical algorithm. The algorithm can be generalized to higher dimensional qudits with the same two-to-one speed-up ratio.

description: Cyclically sheared jammed packings form memories of the shear amplitude at which they were trained by falling into periodic orbits where each particle returns to the identical position in subsequent cycles. While simple models that treat clusters of rearranging particles as isolated two-state systems offer insight into this memory formation, they fail to account for the long training times and multi-period orbits observed in simulated sheared packings. We show that adding interactions between rearranging clusters overcomes these deficiencies. In addition, interactions allow simultaneous encoding of multiple memories which would not have been possible otherwise. These memories are different in an essential way from those found in other systems, such as multiple transient memories observed in sheared suspensions, and contain information about the strength of the interactions.

description: The oncogene of Rous sarcoma virus (v-src) arose by transduction of a cellular gene (c-src). In an effort to explore the mechanism of transduction, we have identified the splice acceptor site used in the genesis of mRNA for v-src, shown that an equivalent site is used in the splicing of mRNA for c-src, and determined the nucleotide sequence from the boundaries of homology between v-src and c-src. Our data indicate that (i) only a portion of c-src is represented within v-src, (ii) the leftward recombination between the genome of the transducing virus and c-src occurred in an intron of the cellular gene, (iii) v-src is in part a spliced version of the corresponding portion of c-src, and (iv) nucleotide sequences represented once in the genome of the transducing virus become duplicated to flank v-src. These findings indicate that the first step in transduction is probably recombination between DNA forms of the transducing viral genome and c-src and otherwise support the prevailing model for transduction by retroviruses. The carboxyl termini of the proteins encoded by v-src and c-src differ appreciably. An unidentified domain of 127 or 128 nucleotides is located at different positions in the genomes of two strains of RSV and gives evidence of being a foreign element that entered the viral genomes by genetic transposition independent of the transduction of src.

description: A low carbon society aims at fighting global warming by stimulating synergic efforts from governments, industry and scientific communities. Decision support systems should be adopted to provide policy makers with possible scenarios, options for prompt countermeasures in case of side effects on environment, economy and society due to low carbon society policies, and also options for information management. A necessary precondition to fulfill this agenda is to face the complexity of this multi-disciplinary domain and to reach a common understanding on it as a formal specification. Ontologies are widely accepted means to share knowledge. Together with semantic rules, they enable advanced semantic services to manage knowledge in a smarter way. Here we address the European Emissions Trading System (EU-ETS) and we present a knowledge base consisting of the EREON ontology and a catalogue of rules. Then we describe two innovative semantic services to manage ETS data and information on ETS scenarios.

Abstract: Nitrocellulose (NC) is commonly used as an energetic binder in explosive and propellant formulations. During the formulation and casting stages NC can be mixed with a variety of plasticisers with the aim of tuning the mechanical properties of the charge to suit the specified requirements. Historically there have been issues with the solubility of NC in various plasticisers which has created manufacturing problems leading to failures of missiles.
The research presented from two programmes of work funded by the WSTC, Propellant Bonding and Nitrocellulose: Degrees of Freedom, has investigated how NC interacts with three plasticisers; Triacetin (TA), Diallyl Phthalate (DAP) and Nitroglycerine (NG). The solubility was investigated using time-lapse microscopy and the chemical interaction was investigated using Attenuated Total Reflectance Infrared Spectroscopy (ATR-FT-IR) and compared with the five modes describing the swelling and dissolution mechanisms of wood and cellulose fibres.
The mechanisms observed for nitrocellulose follow the dissolution modes described for wood and cotton fibres. It was found that TA had the highest solubility with respect to NC whilst NG had the lowest; variation in the swelling and gelation of NC has been rationalised by the crystallinity within the sample. Changes in the cellulosic fibrillar substructure of NC due to nitration and processing results in changes in its crystallinity. This variation of crystallinity subsequently affects the chemical interactions of solvent and plasticiser molecules with NC and the bulk movement of these molecules through the material. ATR-FT-IR demonstrates the presence of constructive bonding interactions between NC and TA or DAP, which manifests as swelling and gelation at the bulk-level. NG exhibits no apparent molecular bonding by IR measurement, and sorption only into the NC fibre, without the extensive swelling and gelation observed in the other regimes.

description: Oil and gas production in the Western United States has increased considerably over the past 10 years. While many of the still limited oil and gas impact assessments have focused on potential human health impacts, the typically remote locations of production in the Intermountain West suggests that the impacts of oil and gas production on national parks and wilderness areas (Class I and II areas) could also be important. To evaluate this, we utilize the Comprehensive Air quality Model with Extensions (CAMx) with a year-long modeling episode representing the best available representation of 2011 meteorology and emissions for the Western United States. The model inputs for the 2011 episodes were generated as part of the Three State Air Quality Study (3SAQS). The study includes a detailed assessment of oil and gas (O&G) emissions in Western States. The year-long modeling episode was run both with and without emissions from O&G production. The difference between these two runs provides an estimate of the contribution of the O&G production to air quality. These data were used to assess the contribution of O&G to the 8 hour average ozone concentrations, daily and annual fine particulate concentrations, annual nitrogen deposition totals and visibility in the modeling domain. We present the results for the Class I and II areas in the Western United States. Modeling results suggest that emissions from O&G activity are having a negative impact on air quality and ecosystem health in our National Parks and Class I areas. Implications: In this research, we use a modeling framework developed for oil and gas evaluation in the western United States to determine the modeled impacts of emissions associated with oil and gas production on air pollution metrics. We show that oil and gas production may have a significant negative impact on air quality and ecosystem health in some national parks and other Class I areas in the western United States. Our findings are of particular interest to federal land managers as well as regulators in states heavy in oil and gas production as they consider control strategies to reduce the impact of development.

description: The squashed entanglement of a quantum channel is an additive function of quantum channels, which finds application as an upper bound on the rate at which secret key and entanglement can be generated when using a quantum channel a large number of times in addition to unlimited classical communication. This quantity has led to an upper bound of $\log((1+η)/(1-η))$ on the capacity of a pure-loss bosonic channel for such a task, where $η$ is the average fraction of photons that make it from the input to the output of the channel. The purpose of the present paper is to extend these results beyond the single-sender single-receiver setting to the more general case of a single sender and multiple receivers (a quantum broadcast channel). We employ multipartite generalizations of the squashed entanglement to constrain the rates at which secret key and entanglement can be generated between any subset of the users of such a channel, along the way developing several new properties of these measures. We apply our results to the case of a pure-loss broadcast channel with one sender and two receivers.

description: Forschungsdaten sind unbestreitbarer Bestandteil des wissenschaftlichen Erkenntnisprozesses. Das digitale Zeitalter eröffnet hier nicht nur vielfältige neue Möglichkeiten, z.B. für Textanalysen, Erhebungen, Klima- oder Genomdaten. Es birgt auch erhebliche Risiken, denen mit Regeln für systematische Archivierung, Austausch und Wiederverwendung, Dokumentation von Daten usw. begegnet werden muss. Es werden Infrastrukturen für das Forschungsdatenmanagement benötigt, die derartige Regelwerke unterstützen. In dieser Präsentation wird der Aufbau eines Datenservicezentrums für Betriebs- und Organisationsdaten skizziert als ein Beispiel für die Kooperation zwischen Fakultät für Soziologie und Bibliothek. Es werden typische Arbeitsabläufe die den Umgang mit Forschungsdaten betreffen ebenso vorgestellt, wie ein Standard für die Beschreibung sozialwissenschaftlicher Daten (DDI). Schließlich wird ein Ausblick auf eine Infrastruktur für Mikrodaten gegeben, die diese Aspekte berücksichtigt.

description: A metamaterial hyperlens offers a unique solution to overcome the diffraction limit by transforming evanescent waves responsible for imaging subwavelength features of an object into propagating waves. However, the first realizations of optical hyperlenses were limited by a narrow working bandwidth and significant resonance-induced loss. Here, we report the first experimental demonstration of a non-resonant waveguide-coupled hyperlens operating in the visible wavelength range. A detailed investigation of various materials systems proves that a radial fan-shaped configuration is superior to the concentric layer-based configuration in that it relies on non-resonant negative dielectric response, and, as a result, enables broadband and low-loss performance in the visible range.

description: In this paper, we give Maurer-Cartan characterizations as well as a cohomology theory for compatible Lie algebras. Explicitly, we first introduce the notion of a bidifferential graded Lie algebra and thus give Maurer-Cartan characterizations of compatible Lie algebras. Then we introduce a cohomology theory of compatible Lie algebras and use it to classify infinitesimal deformations and abelian extensions of compatible Lie algebras. In particular, we introduce the reduced cohomology of a compatible Lie algebra and establish the relation between the reduced cohomology of a compatible Lie algebra and the cohomology of the corresponding compatible linear Poisson structures introduced by Dubrovin and Zhang in their study of bi-Hamiltonian structures. Finally, we use the Maurer-Cartan approach to classify nonabelian extensions of compatible Lie algebras.

description: Transcription of DNA from the RNA genome of retroviruses by reverse transcriptase involves an unusual translocation of the growing chain from the 5' end to the 3' end of the RNA template. In order to elucidate the mechanism by which this translocation occurs, we have used chain termination to analyze nascent viral DNA synthesized in vitro by avian sarcoma virus, and we have determined the nucleotide sequence of appropriate regions of viral DNA isolated from infected cells and cloned into prokaryotic vectors. Our results provide direct experimental evidence for a previously proposed model in which a short terminal redundancy in viral RNA, and a DNA copy of the redundant sequence, are used to allow the growing DNA chain to move from the 5' to the 3' end of the template. Transcription of avian sarcoma virus RNA with purified reverse transcriptase also generates an anomalous product, a hairpin DNA that arises when the initial DNA transcript folds back on itself to continue synthesis. The foldback is mediated by an inverted repeat of 5 nucleotides in the sequence of nascent DNA. Anomalous hairpin DNA is not produced by detergent-activated virions. Thus, constituents of the virons or the configuration of encapsidated viral RNA must faciliatate correct transcription.
