description: A completely elementary and self-contained proof of convergence of Gaussian multiplicative chaos is given. The argument shows further that the limiting random measure is nontrivial in the entire subcritical phase $(γ< \sqrt{2d})$ and that the limit is universal (i.e., the limiting measure is independent of the regularisation of the underlying field)

description: Integration of the human immunodeficiency virus type 1 (HIV-1) cDNA into the genome of a human cell is an essential step in the viral replication cycle. Understanding of the integration process has been facilitated by the development of in vitro assays using specific oligonucleotides and recombinant integrase. However, understanding of the biology of retroviral integration will require in vitro and in vivo model systems using long DNA substrates that mimic the HIV cDNA. We have now studied the activity of recombinant HIV-1 integrase on a linear 4.7 kb double-stranded DNA, containing flanking regions of approximately 200 bp that represent the intact ends of the HIV-1 long terminal repeat (LTR) sequences (mini-HIV). The strand transfer products of the integration reaction can be directly visualized after separation in agarose gels by ethidium bromide staining. The most prominent reaction product resulted from integration of one LTR end into another LTR end (U5 into U5 and U5 into U3). Sequence analysis of the reaction products showed them to be products of legitimate integration preceded by correct processing of the viral LTR ends. Hotspots for integration were detected. Electron microscopy revealed the presence of a range of reaction products resulting from single or multiple integration events. The binding of HIV-1 integrase to mini-HIV DNA was visualized. Oligomers of integrase seem to induce DNA looping whereby the enzyme often appears to be bound to the DNA substrate that adopts the structure of a three-site synapsis that is reminiscent of the Mu phage transposase complex.

title: Essays on Political Economy and Finance
Creators: name: Jayakody, Shashitha Gimhani
Publisher: name: University of Kent
Year: 2023

description: The thesis aims to explore the impact of political institutions on financial and investment policies. It contains three essays examining various aspects of political economy and its intersection with finance. In the first essay, we study how local political corruption and political uncertainty interact in their impact on corporate cash holdings within the United States. We find robust evidence that firms located in states with higher corruption scores react to increases in local political uncertainty by increasing cash holdings more than those in less corrupt settings. This behavior suggests that firms in more corrupt settings find it expedient to raise cash to facilitate the influence of officials in the face of local political risk. Our findings point to a potential channel through which different jurisdictions experience the entrenchment and persistence of corruption. Following on from the evidence of political influence in the first essay, in the second essay, we explore a potential channel through which corruption could activate. In particular, the second essay finds that politically connected firms in the United States increase cash holdings and cash savings more than non-connected firms when faced with rising political uncertainty. We argue that connected firms respond in this manner to influence policymakers so as to navigate the uncertainty that could emerge from new policies and to adjust policies in the interest of the firm. To validate this argument we show that the amount of cash savings by connected firms located in more corrupt states when faced with uncertainty is positively associated with firms' political spending on campaign contributions and lobbying expenses. In the third essay, we investigate the influence of generalized trust on labor regulation. Our findings show that OECD countries with a high level of trust chose to implement less stringent labor dismissal laws, suggesting that trust acts as a substitute for labor laws. We find that in a within-country analysis, trust acts as a substitute for labor laws in countries that are exposed to a low level of corruption whilst trust acts as a complementary for labor laws in countries that are exposed to a greater level of corruption. Furthermore, we validate the substitution effect by showing that trust positively relates to higher foreign direct investment flows. Our findings imply that having strong political institutions that protect the workforce through informal institutions could improve economic outcomes.

description: Members of the RecQ helicase superfamily have been implicated in DNA repair, recombination and replication. Although the genome of the budding yeast Saccharomyces cerevisiae encodes only a single member of this family, there are at least five human RecQ-related genes: RecQL, BLM, WRN, RecQ4 and RecQ5. Mutations in at least three of these are associated with diseases involving a predisposition to malignancies and a cellular phenotype that includes increased chromosome instability. Metazoan RecQ helicases are defined by a core region with characteristic helicase motifs and sequence similarity to Escherichia coli RecQ protein. This core region is typically flanked by extensive, highly charged regions, of largely unknown function. The recently reported human RecQ5, however, has only the core RecQ-homologous region. We describe here the identification of the Drosophila RecQ5 gene. We recovered cDNAs corresponding to three alternative splice forms of the RecQ5 transcript. Two of these generate nearly identical 54 kDa proteins that, like human RecQ5, consist of the helicase core only. The third splice variant encodes a 121 kDa isoform that, like other family members, has a C-terminal extension rich in charged residues. A combination of RACE and cDNA analysis of human RECQ5 demonstrates extensive alternative splicing for this gene also, including some forms lacking helicase motifs and other conserved regions.

description: Regional development classification is one way to look at differences in levels of development outcomes. Some frequently used methods are the shift share, Gain index, the Iindex Williamson and Klassen typology. The development of science in the field of data mining, offers a new way for regional development data classification. This study discusses how the decision tree is used to classify the level of development based on indicators of regional gross domestic product (GDP). GDP Data Central Java and Banten used in this study. Before the data is entered into the decision tree forming algorithm, both the provincial GDP data are classified using Klassen typology. Three decision tree algorithms, namely J48, NBTRee and REPTree tested in this study using cross-validation evaluation, then selected one of the best performing algorithms. The results show that the J48 has a better accuracy rate which is equal to 85.18% compared to the algorithm NBTRee and REPTree. Testing the model is done to the six districts / municipalities in the province of Banten, and shows that there are two districts / cities are still at the development of the status quadrant relatively underdeveloped regions, namely Kota Tangerang and Kabupaten Tangerang. As for the Central Java Province, Kendal, Magelang, Pemalang, Rembang, Semarang and Wonosobo are an area with a quadrant of development also on the status of the region is relatively underdeveloped. Classification model that has been developed is able to classify the level of development fast and easy to enter data directly into the decision tree is formed. This study can be used as an alternative decision support for policy makers in order to determine the future direction of development.

description: Symmetry-protected topological (SPT) phases of matter have been interpreted in terms of anomalies, and it has been expected that a similar picture should hold for SPT phases with fermions. Here, we describe in detail what this picture means for phases of quantum matter that can be understood via band theory and free fermions. The main examples we consider are time-reversal invariant topological insulators and superconductors in 2 or 3 space dimensions. Along the way, we clarify the precise meaning of the statement that in the bulk of a 3d topological insulator, the electromagnetic $θ$-angle is equal to $π$.

Epistemological inquiry into Knowledge and information as two key concepts (with emphasis on the role of context)
Publisher: name: Iranian Research Institute for Information Science and Technology (IranDoc)
Year: 2017

description: This paper redefines the epistemological aspects of information and knowledge with emphasis on the role of context on these two concepts. Whether the context has an explicit or implicit impact, its role in the lifecycle of data and knowledge in the scientific literature has been discussed. Different views of researchers from different scientific areas especially in knowledge and information science has been reviewed. Also the different meanings of information and knowledge in various contexts and the role of context in understanding knowledge have been discussed. The paper has taken analytical review as its methodological approach. In this regards, the philosophical views have been taken into account. Findings indicate that the context has an important role on both the definition and understanding of information and knowledge and that these concepts have different meanings in different contexts.

description: We present a new pseudospectral code, bamps, for numerical relativity written with the evolution of collapsing gravitational waves in mind. We employ the first order generalized harmonic gauge formulation. The relevant theory is reviewed and the numerical method is critically examined and specialized for the task at hand. In particular we investigate formulation parameters, gauge and constraint preserving boundary conditions well-suited to non-vanishing gauge source functions. Different types of axisymmetric twist-free moment of time symmetry gravitational wave initial data are discussed. A treatment of the axisymmetric apparent horizon condition is presented with careful attention to regularity on axis. Our apparent horizon finder is then evaluated in a number of test cases. Moving on to evolutions, we investigate modifications to the generalized harmonic gauge constraint damping scheme to improve conservation in the strong field regime. We demonstrate strong-scaling of our pseudospectral penalty code. We employ the Cartoon method to efficiently evolve axisymmetric data in our 3+1 dimensional code. We perform test evolutions of Schwarzschild perturbed by gravitational waves and by gauge pulses, both to demonstrate the use of our blackhole excision scheme and for comparison with earlier results. Finally numerical evolutions of supercritical Brill waves are presented to demonstrate durability of the excision scheme for the dynamical formation of a blackhole.

The effectiveness of domestic Scientific research on Iran development Indicators
Publisher: name: Iranian Research Institute for Information Science and Technology (IranDoc)
Year: 2017

description: In recent decades, research has growth Increasingly in Iran and, consequently, the country has risen dramatically in world rankings, based on the number of scientific documents. Meanwhile, research policy makers of different societies have concentrated, more and more, on "the effectiveness of researches" and today, their main concern is to ensure that researches are truly contributing to achieve development goals. The issue of "use of research to improve society" has also been emphasized by Iran high-ranking managers and consultants in superior governmental documents, implying their agreement on the importance and necessity of it. Experts' view about the necessity for science to play a fundamental role in the process of society improvement, research impact assessment specialists' models in which they directly emphasize on "promotion of development scale" as the research final expected effect, and the proven high correlation between scientific progress and economic development of societies, create a reasonable expectation that as a consequent of "remarkable progress in research", Iran has experienced a tangible improvement in other aspects and this improvement has been reflected in development indicators. This expectation leads to a question which has been the main reason for this study to be implemented. The purpose of this study is to examine the effectiveness of Iran increasingly research growth in recent three decades on the country development. The study uses a Descriptive-Analytical method and valid secondary data have been the base of analyses. At first, the reliable development indicators for which data were available for a number of countries in an appropriate timeframe were selected. Next, the rank of Iran determined in any indicator among 215 countries (based on the number of countries in World Bank Web site). Then, the trend of Iran's research position was compared with the trend of Iran's position in terms of each development indicator. Results showed that despite a seventy step improvement in research quantity during past 31 years, Iran position have declined 6 steps in terms of GDP per capita during 25 years, 43 steps in terms of inflation rate during 35 years, and 7 steps based on Ecological Footprint Index during 19 years. In other words, Iran hasn’t experienced an acceptable improvement in development level which could be seen as the consequence of its remarkable growth in research. As a conclusion, a shift in all Iran research stakeholders' perspective is necessary from "quantity-oriented view" to "impact-oriented view".

description: Determination quadrant development has an important role in order to determine the achievement of the development of a district, in terms of the sector's gross regional domestic product (GDP). The process of determining the quadrant development typically uses Klassen rules based on its sector GDP. This study aims to provide a new approach in the conduct of regional development quadrant clustering using cluster techniques. Clustering is performed based on the average value of the growth and development of a district contribution compared with the average value and contribution of the development of the province based on data in comparison with a year of data to be compared. Testing models of clustering, performed on a dataset of two provinces, namely Banten (as a data testing) and Central Java (as the training data), to see the accuracy of the classification model proposed. The proposed model consists of two learning methods in it, namely unsupervised (Self Organizing Map / SOM-NN) method and supervised (Naive Bayess). SOM-NN method is used as a learning engine to generate training data for the target Class that will be used in the machine learning Naive Bayess. The results showed the clustering accuracy rate of the model was 98.1%, while the clustering accuracy rate of the model results compared to manual analysis shows the accuracy of the typology Klassen smaller, ie 29.63%. On one side, clustering results of the proposed model is influenced by the number and keagaraman data sets used.

description: We report the detection and mass measurement of a binary lens OGLE-2015-BLG-1285La,b, with the more massive component having $M_1>1.35\,M_\odot$ (80% probability). A main-sequence star in this mass range is ruled out by limits on blue light, meaning that a primary in this mass range must be a neutron star or black hole. The system has a projected separation $r_\perp= 6.1\pm 0.4\,{\rm AU}$ and lies in the Galactic bulge. These measurements are based on the "microlens parallax" effect, i.e., comparing the microlensing light curve as seen from $Spitzer$, which lay at $1.25\,{\rm AU}$ projected from Earth, to the light curves from four ground-based surveys, three in the optical and one in the near infrared. Future adaptive optics imaging of the companion by 30m class telescopes will yield a much more accurate measurement of the primary mass. This discovery both opens the path and defines the challenges to detecting and characterizing black holes and neutron stars in wide binaries, with either dark or luminous companions. In particular, we discuss lessons that can be applied to future $Spitzer$ and $Kepler$ K2 microlensing parallax observations.

The Presence of Iranian Information Science and Library Science Articles in Social Media: An Altmetric Study
Publisher: name: Iranian Research Institute for Information Science and Technology (IranDoc)
Year: 2017

description: Objective: The main objective of the paper is to study the presence of Iranian Information Science & Library Science articles in social media websites and tools. Articles with the highest altmetric scores will be identified and the association between altmetric and citation indicators will be investigated.\nMethodology: This study is an applied research using altmetric data. A total of 563 articles in the area of Information Science & Library Science which specified Iran as their affiliated country and indexed by the Thomson Reuters until the end of 2014, were selected as the population of study. The altmetric bookmarklet, a service provided by Altmetric Institute was used for data collection. Statistical analysis and visualization was conducted using R statistical computing software.\nResults: Out of 563 Iranian IS & LS articles, 72 papers (12.8%) were mentioned at least once in different social media. Twitter (80.55%) stands out as the most promising altmetric source for Iranian IS & LS papers, followed by Mendeley (77.77%) and CiteULike (22.22%). Studying the share of IS & LS papers with altmetric indicators across publication years show that papers published in 2014 have the highest proportion (30%). The results of running a Spearman correlation test revealed statistically significant but moderate relationships between Mendeley and CiteULike readership counts and number of citations in Web of Science.\nConclusion: Altmetric indicators, indices based on activity in social media environments, have the potential to measure scientific impact of researchers beside other scientometric indicators.

The application used for social network analysis is UCINET6. Determining the degree of centralization in the network of knowledge sharing can also help to detect factors may influence it. In this study, the degree of centralization in the network of knowledge sharing communicating with the librarians' qualifications and work experiences were tested. It is also determined the degree centralization of the whole of the knowledge sharing network with 26.76% that is not so satisfactory.  The results show that despite the positive relationship between level of education and the centrality of people, the experience no significant relationship. Statistically, there is also no significant difference between men and women in knowledge sharing degrees of librarians in Ferdowsi University of Mashhad. At the end, according to the results of this research some suggestions are given to increase degrees of knowledge sharing of librarians and generally knowledge sharing degree of the network knowledge sharing.

description: The human genome contains many simple tandem repeats that are widely dispersed and highly polymorphic. At least one group of simple tandem repeats, the DNA trinucleotide repeats, can dramaticallyexpand in size during transmission from one generation to the next to cause disease by a process known as dynamic mutation. We investigated the ability of trinucleotide repeats AAT and CAG to expand in size during DNA replication using a minimal in vitro system composed of the repeat tract, with and without unique flanking sequences, and DNA polymerase. Varying Mg2+concentration and temperature gave dramatic expansions of repeat size during DNA replication in vitro. Expansions of up to 1000-fold were observed. Mismatches partially stabilized the repeat tracts against expansion. Expansions were only detected when the primer was complementary to the repeat tract rather than the flanking sequence. The results imply that cellular environment and whether the growing strand contains a nick or gap are important factors for the expansion process in vivo.

description: We develop a version of Hodge theory for a large class of smooth formally proper quotient stacks $X/G$ analogous to Hodge theory for smooth projective schemes. We show that the noncommutative Hodge-de Rham sequence for the category of equivariant coherent sheaves degenerates. This spectral sequence converges to the periodic cyclic homology, which we canonically identify with the topological equivariant K-theory of $X$ with respect to a maximal compact subgroup of $G$, equipping the latter with a canonical pure Hodge structure. We also establish Hodge-de Rham degeneration for categories of matrix factorizations for a large class of equivariant Landau-Ginzburg models.

description: Extensions of Einstein gravity with quadratic curvature terms in the action arise in most effective theories of quantised gravity, including string theory. This article explores the set of static, spherically symmetric and asymptotically flat solutions of this class of theories. An important element in the analysis is the careful treatment of a Lichnerowicz-type `no-hair' theorem. From a Frobenius analysis of the asymptotic small-radius behaviour, the solution space is found to split into three asymptotic families, one of which contains the classic Schwarzschild solution. These three families are carefully analysed to determine the corresponding numbers of free parameters in each. One solution family is capable of arising from coupling to a distributional shell of matter near the origin; this family can then match on to an asymptotically flat solution at spatial infinity without encountering a horizon. Another family, with horizons, contains the Schwarzschild solution but includes also non-Schwarzschild black holes. The third family of solutions obtained from the Frobenius analysis is nonsingular and corresponds to `vacuum' solutions. In addition to the three families identified from near-origin behaviour, there are solutions that may be identified as `wormholes', which can match symmetrically on to another sheet of spacetime at finite radius.

A Conceptual Framework for Knowledge Architecture in Large-Scale Organizations
Publisher: name: Iranian Research Institute for Information Science and Technology (IranDoc)
Year: 2017

description: The main concern for most organizations in this age, which has been called the age of knowledge-based economy, is their success and superiority in competitive markets. Reviewing the parameters that might have been effective on the success of operationalizing a knowledge management project leads us to a potential factor as knowledge architecture. With regard to the significant effect of knowledge management in the efficiency of organizations and the inclination of current organizations toward large-scale, we try to come up with a suitable architectural framework in such organizations. The initial structure of the framework was established based on the information architectural framework of Zachman. Then, we arrived at the ideal knowledge architecture framework by adding service abstraction and architecture level dimension besides changing the field of all the cells within Zachman’s framework from information into knowledge. This research is descriptive in method and its validity is confirmed by executing a case study and soliciting the opinions of some knowledge architecture experts. The results indicate feasibility of applying framework to other knowledge-intensive large-scale firms and the findings of paper may be beneficial for architects in the knowledge area.

description: There has been great interest recently in therapeutic use of nucleic acids including genes, ribozymes and antisense oligonucleotides. Despite recent improvements in delivering antisense oligonucleotides to cells in culture, nucleic acid-based therapy is still often limited by the poor penetration of the nucleic acid into the cytoplasm and nucleus of cells. In this report we describe nucleic acid delivery to cells using a series of novel cationic amphiphiles containing cholic acid moieties linked via alkylamino side chains. We term these agents 'molecular umbrellas' since the cationic alkylamino chains provide a 'handle' for binding of nucleic acids, while the cholic acid moieties are likely to interact with the lipid bilayer allowing the highly charged nucleic acid backbone to traverse across the cell membrane. Optimal gene and oligonucleotide delivery to cells was afforded by a derivative (amphiphile 5) containing four cholic acid moieties. With this amphiphile used as a constituent in cationic liposomes, a 4-5 log increase in reporter gene delivery was measured. This amphiphile used alone provided a 250-fold enhancement of oligo-nucleotide association with cells as observed by flow cytometry. A substantial fraction of cells exposed to complexes of amphiphile 5 and fluorescent oligo-nucleotide showed nuclear accumulation of the fluorophore. Enhanced pharmacological effectiveness of antisense oligonucleotides complexed with amphiphile 5 was observed using an antisense splicing correction assay that activates a Luciferase reporter. Intracellular delivery, nuclear localization and pharmacological effectiveness of oligonucleotides using amphiphile 5 were similar to those afforded by commercial cytofectins. However, in contrast to most commercial cytofectins, the umbrella amphiphile showed substantial delivery activity even in the presence of high concentrations of serum.
Nucleotide excision repair 3' endonuclease XPG stimulates the activity of base excision repairenzyme thymine glycol DNA glycosylase

description: An ionizing radiation-induced DNA lesion, thymine glycol, is removed from DNA by a thymine glycol DNA glycosylase with an apurinic/apyrimidinic (AP) lyase activity encoded by the Escherichia coli endonuclease III ( nth ) gene and its homolog in humans. Cells from Cockayne syndrome patients with mutations in the XPG gene show approximately 2-fold reduced global repair of thymine glycol. Hence, I decided to investigate the molecular mechanism of the effect of XPG protein observed in vivo on thymine glycol removal by studying the interactions of XPG protein and human endonuclease III (HsNTH) protein in vitro and the effect of XPG protein on the activity of HsNTH protein on a substrate containing thymine glycol. The XPG protein stimulates the binding of HsNTH protein to its substrate and increases its glycosylase/AP lyase activity by a factor of approximately 2 through direct interaction between the two proteins. These results provide in vitro evidence for a second function of XPG protein in DNA repair and a mechanistic basis for its stimulatory activity on HsNTH protein.

description: Measurements of explosive nucleosynthesis yields in core-collapse supernovae provide tests for explosion models. We investigate constraints on explosive conditions derivable from measured amounts of nickel and iron after radioactive decays using nucleosynthesis networks with parameterized thermodynamic trajectories. The Ni/Fe ratio is for most regimes dominated by the production ratio of 58Ni/(54Fe + 56Ni), which tends to grow with higher neutron excess and with higher entropy. For SN 2012ec, a supernova that produced a Ni/Fe ratio of $3.4\pm1.2$ times solar, we find that burning of a fuel with neutron excess $η\approx 6\times 10^{-3}$ is required. Unless the progenitor metallicity is over 5 times solar, the only layer in the progenitor with such a neutron excess is the silicon shell. Supernovae producing large amounts of stable nickel thus suggest that this deep-lying layer can be, at least partially, ejected in the explosion. We find that common spherically symmetric models of $M_{\rm ZAMS} \lesssim 13$ Msun stars exploding with a delay time of less than one second ($M_{\rm cut} < 1.5$ Msun) are able to achieve such silicon-shell ejection. Supernovae that produce solar or sub-solar Ni/Fe ratios, such as SN 1987A, must instead have burnt and ejected only oxygen-shell material, which allows a lower limit to the mass cut to be set. Finally, we find that the extreme Ni/Fe value of 60-75 times solar derived for the Crab cannot be reproduced by any realistic-entropy burning outside the iron core, and neutrino-neutronization obtained in electron-capture models remains the only viable explanation.

description: We study semiconductor excitons confined in an electrostatic trap of a GaAs bilayer heterostructure. We evidence that optically bright excitonic states are strongly depleted while cooling to sub-Kelvin temperatures. In return, the other accessible and optically dark states become macroscopically occupied so that the overall exciton population in the trap is conserved. These combined behaviours constitute the spectroscopic signature for the mostly dark Bose-Einstein condensation of excitons, which in our experiments is restricted to a dilute regime within a narrow range of densities, below a critical temperature of about 1K.
