description: We investigate the influence of interactions on the star formation by studying a sample of almost 1500 of the nearest galaxies, all within a distance of ~45 Mpc. We define the massive star formation rate (SFR), as measured from far-IR emission, and the specific star formation rate (SSFR), which is the former quantity normalised by the stellar mass of the galaxy, and explore their distribution with morphological type and with stellar mass. We then calculate the relative enhancement of these quantities for each galaxy by normalising them by the median SFR and SSFR values of individual control populations of similar non-interacting galaxies. We find that both SFR and SSFR are enhanced in interacting galaxies, and more so as the degree of interaction is higher. The increase is, however, moderate, reaching a maximum of a factor of 1.9 for the highest degree of interaction (mergers). The SFR and SSFR are enhanced statistically in the population, but in many individual interacting galaxies they are not enhanced at all. We discuss how those galaxies with the largest SFR and/or SSFR enhancement can be defined as starbursts. This study is based on a representative sample of nearby galaxies, including many low-mass and dwarf/irregular galaxies, and we argue that it should be used to place constraints on studies based on samples of galaxies at larger distances, beyond the local Universe.

description: Although one of the crucial aspects of research evaluation, there is lack of information in literature about the ethics evaluation of research proposals. Research proposal applicants should be aware of the research ethics issues which could arise during research process, but the reason for the lack of data in the literature is because the ethics evaluation data are difficult to collect due to the sensitivity of the information. In this research project, we collected the data on ethics review process in two funding programmes of Horizon 2020 (H2020): the Marie Skłodowska-Curie Actions (MSCA) (only Individual Fellowships-IF and Innovative Training Networks-ITN) and the European Research Council (ERC). In the first part, the aim of the project was to assess the number and the characteristics of the ethics issues identified by the applicant and to compare those data with the ethics issues identified by the ethics experts during evaluation process. We also describe the data by funding scheme (IF, ITN and ERC), call year and research domain (Life Sciences, Physical Sciences and Engineering and Social Sciences and Humanities). In the second part of the study, we plan to analyse the characteristics of ethics requirements of the same proposals which need to be fulfilled before the project starts, and to compare them by funding scheme, call year and research domain. The results of this study will provide information about the nature of the ethics issues, identify the trends about the ethics issues in H2020 proposals and to identify groups which need additional assistance related to identification of ethics issues in research proposals.

description: Metal oxide-based semiconductor materials have shown to be good contenders for the solar energy conversion reactions utilizing CO2 as energy storing agent. The influence of light on ad- and desorption of CO2 was investigated on different zinc oxide, titania and cerium zirconium oxide nanomaterials by means of DRIFTS and TPD method. The phenomenon of “IR-Blackening” was observed and found to be caused by interaction between phonons and electrons. No direct influence of UV-Irradiation on adsorption of CO2 on zinc oxide was confirmed, while on titania the preference changed under irradiation.

description: We present an investigation of spinning black holes in Einstein--Gauss-Bonnet--dilaton (EGBd) theory. The solutions are found within a non-perturbative approach, by directly solving the field equations. These stationary axially symmetric black holes are asymptotically flat. They possess a non-trivial scalar field outside their regular event horizon. We present an overview of the parameter space of the solutions together with a study of their basic properties. We point out that the EGBd black holes can exhibit some physical differences when compared to the Kerr solution. For example, their mass is always bounded from below, while their angular momentum can exceed the Kerr bound, Also, in contrast to the Kerr case, the extremal solutions are singular, with the scalar field diverging on the horizon.

Trip the freaking light fantastic: Syntactic structure in English verbal idioms
Creators: name: Neal, Anissa
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2017

description: In past scholarship, idioms have been discussed from a mostly semantic perspective; authors have been primarily concerned with how idiomatic meaning is composed and stored (Swinney and Cutler 1979; Gibbs 1980; 1986). This thesis investigates idioms' syntactic behavior and concludes that all verbal idioms of English have stored, internal syntactic structure. Vacuous modification (i.e. modification that does not contribute to the semantics of the phrase), metalinguistic modification (i.e. modification that indicates non-literal readings), aspect, and subject-oriented adverbs (SOAs) are used to test a variety of idioms for evidence of syntactic structure.. There are restrictions on the syntactic processes some idioms can undergo (i.e. passivization and raising constructions). However, this is not due to their lack of internal syntax, but how their meaning is mapped onto the internal syntax.

description: Consider the maximal operator $$\mathscr{C} f(x) = \sup_{λ\in\mathbb{R}}\Big|\sum_{\substack{y\in\mathbb{Z}^n\setminus\{0\}}} f(x-y) e(λ|y|^{2d}) K(y)\Big|,\quad (x\in\mathbb{Z}^n),$$ where $d$ is a positive integer, $K$ a Calderón-Zygmund kernel and $n\ge 1$. This is a discrete analogue of a real-variable operator studied by Stein and Wainger. The nonlinearity of the phase introduces a variety of new difficulties that are not present in the real-variable setting. We prove $\ell^2(\mathbb{Z}^n)$-bounds for $\mathscr{C}$, answering a question posed by Lillian Pierce.

The GALEX Ultraviolet Virgo Cluster Survey (GUViCS). VI: The UV luminosity function of the Virgo cluster and its surrounding regions

description: We use the GALEX data of the GUViCS survey to construct the NUV luminosity function of the Virgo cluster over ~ 300 deg.2, an area covering the cluster and its surrounding regions up to ~ 1.8 virial radii. The NUV luminosity function is also determined for galaxies of different morphological type and NUV-i colour, and for the different substructures within the cluster. These luminosity functions are robust vs. statistical corrections since based on a sample of 833 galaxies mainly identified as cluster members with spectroscopic redshift (808) or high-quality optical scaling relations (10). We fit these luminosity functions with a Schechter function, and compare the fitted parameters with those determined for other nearby clusters and for the field. The faint end slope of the Virgo NUV luminosity function (alpha = -1.19), here sampled down to ~ NUV = -11.5 mag, is significantly flatter than the one measured in other nearby clusters and similar to the field one. Similarly M* = -17.56 is one-to-two magnitudes fainter than measured in Coma, A1367, the Shapley supercluster, and the field. These differences seem due to the quite uncertain statistical corrections and the small range in absolute magnitude sampled in these clusters. We do not observe strong systematic differences in the overall NUV luminosity function of the core of the cluster with respect to that of its periphery. We notice, however, that the relative contribution of red-to-blue galaxies at the faint end is inverted, with red quiescent objects dominating the core of the cluster and star forming galaxies dominating beyond one virial radius. These observational evidences are discussed in the framework of galaxy evolution in dense environments.

Cryptanalysis and improvement of Wu-Cai-Wu-Zhang's quantum private comparison protocol

description: In a recent paper (Int. J. Quantum Inf. 17 (2019) 1950026), the authors discussed the shortcomings in the security of a quantum private comparison protocol that we previously proposed (Int. J. Quantum Inf. 15 (2017) 1750014). They also proposed a new protocol aimed to avoid these problems. Here we analysis the information leaked in their protocol, and find that it is even less secure than our protocol in certain cases. We further propose an improved version which has the following advantages: (1) no entanglement needed, (2) quantum memory is no longer required, and (3) less information leaked. Therefore, better security and great feasibility are both achieved.

An optical implementation of quantum bit commitment using infinite-dimensional systems
Creators: name: He, Guang Ping
Publisher: name: arXiv
Year: 2019
Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: Unconditionally secure quantum bit commitment (QBC) was widely believed to be impossible for more than two decades. But recently, based on an anomalous behavior found in quantum steering, we proposed a QBC protocol which can be unconditionally secure in principle. The protocol requires the use of infinite-dimensional systems, therefore it may seem less feasible in practice. Here we propose a quantum optical method based on Mach-Zehnder interferometer, which gives a very good approximation to such infinite-dimensional systems. Thus, it enables a proof-of-principle experimental implementation of our protocol, which can also serve as a practically secure QBC scheme. Other multi-party cryptographic protocols such as quantum coin tossing can be built upon it too. Our approach also reveals a relationship between infinity and non-locality, which may have an impact on the research of fundamental theories.

description: To make progress in science, we often build abstract representations of physical systems that meaningfully encode information about the systems. The representations learnt by most current machine learning techniques reflect statistical structure present in the training data; however, these methods do not allow us to specify explicit and operationally meaningful requirements on the representation. Here, we present a neural network architecture based on the notion that agents dealing with different aspects of a physical system should be able to communicate relevant information as efficiently as possible to one another. This produces representations that separate different parameters which are useful for making statements about the physical system in different experimental settings. We present examples involving both classical and quantum physics. For instance, our architecture finds a compact representation of an arbitrary two-qubit system that separates local parameters from parameters describing quantum correlations. We further show that this method can be combined with reinforcement learning to enable representation learning within interactive scenarios where agents need to explore experimental settings to identify relevant variables.

Treatment options for Pityriasis Rubra Pilaris: A Scoping Review

Subjects: subject: Medicine and Health Sciences

description: Pityriasis rubra pilaris (PRP) is a rare papulosquamous inflammatory dermatosis of uncertain etiology. Past reports estimate incidence of 1 in 5000 new patient visits in Great Britain and 1 in 50,000 visits in India. PRP has widely heterogeneous presentations, which Griffith classified into five clinical subtypes according to clinical features, age of onset, and prognosis. There is a paucity of high-quality evidence for treatments commonly prescribed for PRP; the evidence mostly consists of case reports and case series. Past reviews failed to be systematic in their search strategy, excluded new treatment modalities, or only investigated specific pathway targets (anti-TNF, anti-IL-12/23, and anti-IL-17)4,5,8. No scoping review has been previously published on the topic of PRP treatments. This scoping review will provide a comprehensive review of treatments for pityriasis rubra pilaris, examine the emerging evidence of immunotherapy, and inform current clinical practice.

description: We report an entropy-driven orientational hopping transition in a magnetically confined colloidal Janus rod. In a magnetic field, the sedimented rod randomly hops between horizontal and vertical states: the latter state comes at a substantial gravitational cost at no reduction of magnetic potential energy. The probability distribution over the angles of the rod shows that the presence of an external magnetic field leads to the emergence of a metastable vertical state separated from the ground state by an effective barrier. This barrier does not come from the potential energy but rather from the vast gain in phase space available to the rod as it approaches the vertical state. The loss of rotational degree of freedom that gives rise to this effect is a statistical mechanical analogue of the phenomenon of gimbal lock from classical mechanics.

Changing Places to See: Otherness and Essentialism in Le Comte de Monte-Cristo
Creators: name: McLean, Donald
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2017

description: Alexandre Dumas’s novels, especially Le Comte de Monte-Cristo, engage with cultural hegemonies and French social norms. This thesis will examine how Dumas explores these norms in Monte-Cristo, specifically in analyzing the Orientalist tropes in the Sinbad the Sailor episodes. Edmond Dantès, the main character, uses the persona of Sinbad to create a myth that will permeate French aristocracy in order to advance his revenge plot. The use of Sinbad inherently relies on Orientalist tropes, but Dantès, aware of their strategic power, inverts them to confront cultural hegemonies. Ultimately, Dantès’s plot succeeds in part because of the French aristocracy’s inability, or unwillingness, to critically engage with these tropes. Dantès, however, abstracts himself in order to assume multiple personas, and is ultimately unable to reestablish himself as an individual at the novel’s closing. Dantès’s strategic essentialism thus allows him to achieve his revenge against society but denies him closure as an individual.

Finding The Lost Colony (1937): Paul Green, Symphonic Drama, and the History of a Collaboration
Creators: name: Bentley, Christa Anne
Publisher: name: University of North Carolina at Chapel Hill
Year: 2012

description: In 1937, Paul Green wrote and produced The Lost Colony, a drama about the mysterious disappearance of the Roanoke Colony in 1587 on North Carolina's Outer Banks. As he was writing, Green envisioned The Lost Colony as a new genre of theater, calling it a symphonic drama. To achieve this, Green enlisted the help of composer Lamar Stringfield and arranger Adeline McCall. The play includes Elizabethan carols and Native American dances, creating a musical background thought to portray a realistic historical setting. In addition to examining the ideas behind symphonic drama, I explore the musical identity that The Lost Colony creates for the state of North Carolina within the context of the New South. Furthermore, I examine The Lost Colony within the frame of the Federal Theatre Project, exploring the intersections of regional projects and national trends.

description: We study the system IFP of intuitionistic fixed point logic, an extension of intuitionistic first-order logic by strictly positive inductive and coinductive definitions. We define a realizability interpretation of IFP and use it to extract computational content from proofs about abstract structures specified by arbitrary classically true disjunction free formulas. The interpretation is shown to be sound with respect to a domain-theoretic denotational semantics and a corresponding lazy operational semantics of a functional language for extracted programs. We also show how extracted programs can be translated into Haskell. As an application we extract a program converting the signed digit representation of real numbers to infinite Gray-code from a proof of inclusion of the corresponding coinductive predicates.

description: Alisporivir is a cyclophilin inhibitor with demonstrated in vitro and in vivo activity against hepatitis C 11 virus (HCV). We estimated antiviral effectiveness of alisporivir alone or in combination with 12 pegylated-Inteferon (peg-IFN) in 88 patients infected with different HCV genotypes treated for four 13 weeks. The pharmacokinetics of both drugs were modeled and used as driving functions for the viral 14 kinetic model. Genotype was found to significantly affect pegylated-Inteferon effectiveness ($ε$= 86.3% 15 and 99.1% in genotype-1/4 and genotype-2/3, respectively, p\textless{}10 -7) and infected cells loss rate ($δ$= 16 0.22 vs 0.39 day -1 in genotype-1/4 and genotype-2/3, respectively, p\textless{}10 -6). Alisporivir effectiveness 17 was not significantly different across genotype and was high for doses $\ge$600 mg QD. We simulated 18 virologic responses with other alisporivir dosing regimens in HCV genotype-2/3 patients using the 19 model. Our predictions consistently matched the observed responses, demonstrating that this model 20 could be a useful tool for anticipating virologic response and optimize alisporivir-based therapies.

description: Filtered back projection (FBP) methods are the most widely used reconstruction algorithms in computerized tomography (CT). The ill-posedness of this inverse problem allows only an approximate reconstruction for given noisy data. Studying the resulting reconstruction error has been a most active field of research in the 1990s and has recently been revived in terms of optimal filter design and estimating the FBP approximation errors in general Sobolev spaces. However, the choice of Sobolev spaces is suboptimal for characterizing typical CT reconstructions. A widely used model are sums of characteristic functions, which are better modelled in terms of Besov spaces $\mathrm{B}^{α,p}_q(\mathbb{R}^2)$. In particular $\mathrm{B}^{α,1}_1(\mathbb{R}^2)$ with $α\approx 1$ is a preferred model in image analysis for describing natural images. In case of noisy Radon data the total FBP reconstruction error $$\|f-f_L^δ\| \le \|f-f_L\|+ \|f_L - f_L^δ\|$$ splits into an approximation error and a data error, where $L$ serves as regularization parameter. In this paper, we study the approximation error of FBP reconstructions for target functions $f \in \mathrm{L}^1(\mathbb{R}^2) \cap \mathrm{B}^{α,p}_q(\mathbb{R}^2)$ with positive $α\not\in \mathbb{N}$ and $1 \leq p,q \leq \infty$. We prove that the $\mathrm{L}^p$-norm of the inherent FBP approximation error $f-f_L$ can be bounded above by \begin{equation*} \|f - f_L\|_{\mathrm{L}^p(\mathbb{R}^2)} \leq c_{α,q,W} \, L^{-α} \, |f|_{\mathrm{B}^{α,p}_q(\mathbb{R}^2)} \end{equation*} under suitable assumptions on the utilized low-pass filter's window function $W$. This then extends by classical methods to estimates for the total reconstruction error.

description: One of the most important questions asked throughout the COVID-19 pandemic has concerned the fatality rate of the disease. The ratio of fatalities to confirmed cases has proven problematic due to the incidence of asymptomatic or mildly symptomatic infections as well as variations in test availability. Consequently, the burden of COVID-19 is more accurately conveyed by assessments of the infection fatality rate (IFR), the ratio of fatal outcomes to total infections. We employ a Bayesian model to estimate the IFR in multiple developing countries from representative serology studies and official death reports, and take into account economic and healthcare system characteristics, as well as issues such as seroreversion, death underreporting, and survivorship bias.

description: For decades, removable partial dentures (RPDs) have been a standard treatment for partial edentulism despite major shortcomings. To alleviate these problems, implants have been incorporated to provide additional support, increase stability, and maintain bone. This prospective study incorporated dental implants to evaluate; a comparison of impact on oral health quality of life RPDs and implant supported removable partial dentures (ISRPDs); prosthetic outcome of ISRPDs; 6 month survival of 6mm Astra-tech implants. Ten patients received new RPDs, but prior to fabrication of a RPD, 6 mm dental implants were placed in the posterior edentulous areas. Examination of oral health occurred at 6 weeks and 12 weeks after delivery of the RPD. At 12 weeks, attachments were inserted and the RPD was converted to implant ISRPD. Subsequent follow-ups at 18 weeks and 26 weeks demonstrated a statistical improvement in oral health quality of life. All sixteen implants survived.

description: With calls to “make America great again”, many Americans, especially White Americans, feel as though the country has lost something of value. These calls also suggest that there is a previous time in the country’s history that Americans can reclaim. These feelings hinge on the construct of collective nostalgia. The purpose of this research is to explore a particular manifestation of collective nostalgia--racial nostalgia--or longing for a previous time in a racial groups’ past. Specifically, we will explore how racial nostalgia relates to the perception of realistic and symbolic threat, the endorsement of extreme anti-immigrant policies, and the endorsement of White nationalist beliefs.

description: Considering the need for cost/performance prediction and optimization of superconducting maglev vehicles, we develop and validate here a 3D finite element model to simulate superconducting linear magnetic bearings. Then we reduce the 3D model to a 2D model in order to decrease the computing time. This allows us to perform in a reasonable time a stochastic optimization considering the superconductor properties and the vehicle operation. We look for the permanent magnet guideway geometry that minimizes the cost and maximizes the lateral force during a displacement sequence, with a constraint on the minimum levitation force. The displacement sequence reproduces a regular maglev vehicle operation with both vertical and lateral movements. For the sake of comparison, our reference is the SupraTrans prototype bearing. The results of the optimization suggest that the bearing cost could be substantially reduced, while keeping the same performances as the initial design. Alternatively, the performances could be significantly improved for the same original cost.
