description: In this letter we study the effect of time-reversal symmetric impurities on the Josephson supercurrent through two dimensional helical metals such as on topological insulator surface state. We show that contrary to the usual superconducting-normal metal-superconducting junctions, the suppression of supercurrent in superconducting-helical metal-superconducting junction is mainly due to fluctuations of impurities in the junctions. Our results, which is a condensed matter realization of a part of the MSW effect for neutrinos, shows that the relationship between normal state conductance and critical current of Josephson junctions is significantly modified for Josephson junctions on the surface of topological insulators. We also study the temperature-dependence of supercurrent and present a two fluid model which can explain some of recent experimental results in Josephson junctions on the edge of topological insulators.

description: The design of a beam transport system for the electron bunches of a Laser Wakefield Accelerator (LWFA) is challenging due to the large relative energy spread of the bunches. For the realization of an undulator radiation source at the LWFA based on a transverse gradient undulator (TGU) a well adapted transport system is essential. In this thesis the layout of such a system including the compensation of the energy spread and first experimental tests are presented.

Family Gauge Boson Production at the LHC

Year: 2015
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: Family gauge boson production at the LHC is investigated according to a $U(3)$ family gauge model with twisted family number assignment. In the model we study, a family gauge boson with the lowest mass, $A_1^{\ 1}$, interacts only with the first generation leptons and the third generation quarks. (The family numbers are assigned, for example, as $(e_1, e_2, e_3)= (e^-, μ^-, τ^-)$ and $(d_1, d_2, d_3)=(b, d, s) $[or $(d_1, d_2, d_3)=(b, s, d)$]). In the model, the family gauge coupling constant is fixed by relating to the electroweak gauge coupling constant. Thus measurements of production cross sections and branching ratios of $A_1^{\ 1}$ clearly confirm or rule out the model. We calculate the cross sections of inclusive $A_1^{\ 1}$ production and $b \bar{b} \, (t \bar{t})$ associated $A_1^{\ 1}$ production at $\sqrt{s} = 14~\text{TeV}$ and $100~\text{TeV}$. With the dielectron production cross section, we discuss the determination of diagonalizing matrix of quark mass matrix, $U_{u}$ and $U_{d}$, respectively.

description: This study presents an analysis of bibliographic information on title pages of Russian monographs. The bibliographic data are examined in terms of visual characteristics of individual bibliographic elements and those of separations between elements. Visual properties used in this analysis consist of both primitives and coordinates. A separation between bibliographic elements is identified by changes in primitives or the existence of coordinates between two elements. Additionally, this study records any inconsistent or incomplete bibliographic information in the sample. The results of this study are compared to a similar study of English materials.  Comparison revealed no major differences in terms of inclusion of bibliographic elements on title pages. The two samples differed, however, with respect to the location of some elements, such as Author Name, Publisher and Series Title. Another important finding is that a majority of Russian title pages do not provide full Author Name, which has significant implications for the creation of personal name headings according to AACR2.

Origin of Negative Density and Modulus in Acoustic Metamaterials
Creators: name: Lee, Sam Hyeon
name: Wright, Oliver B.
Publisher: name: arXiv
Year: 2015
Subjects: subject: Classical Physics (physics.class-ph)
subject: FOS: Physical sciences

description: This paper provides a review and fundamental physical interpretation for the effective densities and moduli of acoustic metamaterials. We introduce the terminology of hidden force and hidden source of volume: the effective density or modulus is negative when the hidden force or source of volume is larger than, and operates in antiphase to, respectively, the force or volume change that would be obtained in their absence. We demonstrate this ansatz for some established acoustic metamaterials with elements based on membranes, Helmholtz resonators, springs and masses. The hidden force for membrane-based acoustic metamaterials, for instance, is the force from the membrane tension. The hidden source for a Helmholtz-resonator-based metamaterial is the extra air volume injected from the resonator cavity. We also explain the analogous concepts for pure mass-and-spring systems, in which case hidden forces can arise from masses and springs fixed inside other masses, whereas hidden sources - more aptly termed hidden expanders of displacement in this case - can arise from light rigid trusses coupled to extra degrees of freedom for mechanical motion such as the case of coupling to masses that move at right angles to the wave-propagation direction. This overall picture provides a powerful tool for conceptual understanding and design of new acoustic metamaterials, and avoids common pitfalls involved in determining the effective parameters of such materials.

description: Anthropogenic stressors continue to escalate worldwide, driving unprecedented declines in reef environmental conditions and coral health. One approach to better understand how corals can function in the future is to examine coral populations that thrive within present day naturally extreme habitats. We applied untargeted metabolomics (Gas Chromatography-Mass Spectrometry (GC-MS)) to contrast metabolite profiles of Pocillopora acuta colonies from hot, acidic and deoxygenated mangrove environments versus those from adjacent reefs. Under ambient temperatures, P. acuta predominantly associated with endosymbionts of the genera Cladocopium (reef) or Durusdinium (mangrove), exhibiting elevated metabolism in mangrove through energy-generating and biosynthesis pathways compared to reef populations. Under transient heat stress, P. acuta endosymbiont associations were unchanged. Reef corals bleached and exhibited extensive shifts in symbiont metabolic profiles (whereas host metabolite profiles were unchanged). By contrast, mangrove populations did not bleach and solely the host metabolite profiles were altered, including cellular responses in inter-partner signalling, antioxidant capacity and energy storage. Thus mangrove P. acuta populations resist periodically high-temperature exposure via association with thermally tolerant endosymbionts coupled with host metabolic plasticity. Our findings highlight specific metabolites that may be biomarkers of heat tolerance, providing novel insight into adaptive coral resilience to elevated temperatures.
Pursuing Pro Se Litigants in North Carolina: How They Access Legal Information and How Libraries Can Do More
Creators: name: Plott, Jasmine
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2018

description: Individuals who are representing themselves in a legal matter, known as pro se litigants, are increasingly common. Several of these individuals have no experience with the legal system, and having easily accessible areas where these individuals can conduct this legal research and access the resources they need is crucial. However, since the closing of the county courthouse libraries, North Carolina is unique in that it is a state that has no public law libraries, which are designed to solely serve the needs of the public. While there are public libraries and academic law libraries that the public can access, neither of these institutions are equipped to help pro se patrons in the way that a public law library would. This study explores how North Carolina is currently meeting the needs of pro se patrons and identifies gaps in service to these patrons generally and how they can be better met.

description: The purpose of this thesis is to examine end users' perceptions of the enabling and constraining aspects of computer technology. I argue that technology can be understood best when one examines both forces. Eleven faculty and staff members within four academic departments at a mid-sized Southeastern university participated in the study. Participants were asked to discuss their use of and perceptions about technology in general and upgrades, including a recent campus-wide upgrade. Three major conclusions emerged. First, technology use is efficient when it is accessible, easy, quick, reliable, and backed by support, but these qualities must be combined with stability, constancy, and certainty of purpose in order to realize technology's full potential. Secondly, the study supports structuration theory by showing that even technology's most positively perceived attributes possess both enabling and constraining features. Thirdly, user types do not significantly affect the overall enablement and constraint perceived in technology.

description: The application of enzymes as biocatalysts in industrial processes has great potential due to their outstanding stereo-, regio- and chemoselectivity. Using autodisplay, enzymes can be immobilized on the cell surface of Gram-negative bacteria such as 'Escherichia coli'. In the present study, the surface display of an alcohol dehydrogenase (ADH) and a cyclohexanone monooxygenase (CHMO) on 'E. coli' was investigated. Displaying these enzymes on the surface of 'E. coli' resulted in whole-cell biocatalysts accessible for substrates without further purification. An apparent maximal reaction velocity VMAX(app) for the oxidation of cyclohexanol with the ADH whole-cell biocatalysts was determined as 59.9 mU ml−1. For the oxidation of cyclohexanone with the CHMO whole-cell biocatalysts a VMAX(app) of 491 mU ml−1 was obtained. A direct conversion of cyclohexanol to ε-caprolactone, which is a known building block for the valuable biodegradable polymer polycaprolactone, was possible by combining the two whole-cell biocatalysts. Gas chromatography was applied to quantify the yield of ε-caprolactone. 1.12 mM ε-caprolactone was produced using ADH and CHMO displaying whole-cell biocatalysts in a ratio of 1:5 after 4 h in a cell suspension of OD578nm 10. Furthermore, the reaction cascade as applied provided a self-sufficient regeneration of NADPH for CHMO by the ADH whole-cell biocatalyst.

description: We have developed a refined and optimized version of the Warsaw Test Particle Model of interstellar neutral gas in the heliosphere, specially tailored for analysis of IBEX-Lo observations. The former version of the model was used in the analysis of neutral He observed by IBEX that resulted in an unexpected conclusion that the interstellar neutral He flow vector was different than previously thought and that a new population of neutral He, dubbed the Warm Breeze, exists in the heliosphere. It was also used in the reanalysis of Ulysses observations that confirmed the original findings on the flow vector, but suggested a significantly higher temperature. The present version model has two strains targeted for different applications, based on an identical paradigm, but differing in the implementation and in the treatment of ionization losses. We present the model in detail and discuss numerous effects related to the measurement process that potentially modify the resulting flux of ISN He observed by IBEX, and identify those of them that should not be omitted in the simulations to avoid biasing the results. This paper is part of a coordinated series of papers presenting the current state of analysis of IBEX-Lo observations of ISN He. Details of the analysis method are presented by Swaczyna et al. 2015, and results of the analysis are presented by Bzowski et al. 2015.

description: This research examined the concept of serendipity within the context of library and information science. Serendipity was defined as a happy accident in which an information seeker unexpectedly stumbled across relevant information. This research addressed the following questions: What information seeking strategies do experienced searchers employ in order to provide opportunities for the serendipitous discovery of information? The purpose of this research was to study the experiences and ideas of experienced information seekers in order to better understand and provide opportunities for serendipitous discoveries. To address this research question and purpose, I conducted qualitative interviews with five faculty members of the School of Information and Library Science at the University of North Carolina - Chapel Hill and six public librarians. The interviews were audiotaped, transcribed, and analyzed. The major findings of this study were that experienced searchers defined serendipity as an instance that is both unplanned and useful, and that the participants overwhelmingly did not attach a stigma to serendipity. The participants identified many sources of serendipity, including shelf-browsing and co-workers, made suggestions for improving serendipity in the physical library, particularly increasing displays and facing books out, and they also made suggestions for improving serendipity in information retrieval systems, particularly attaching some type of recommender system to the library catalog.

description: Analyses of the three valence-quark bound-state problem in relativistic quantum field theory predict that the nucleon may be understood primarily as a Borromean bound-state, in which binding arises mainly from two separate effects. One originates in non-Abelian facets of QCD that are expressed in the strong running coupling and generate confined but strongly-correlated colour-antitriplet diquark clusters in both the scalar-isoscalar and pseudovector-isotriplet channels. That attraction is magnified by quark exchange associated with diquark breakup and reformation. Diquark clustering is driven by the same mechanism which dynamically breaks chiral symmetry in the Standard Model. It has numerous observable consequences, the complete elucidation of which requires a framework that also simultaneously expresses the running of the coupling and masses in the strong interaction. Planned experiments are capable of validating this picture.

description: The 16 Cyg system is composed of two solar analogs with similar masses and ages. A red dwarf is in orbit around 16 Cyg A whereas 16 Cyg B hosts a giant planet. The abundances of heavy elements are similar in the two stars but lithium is much more depleted in 16 Cyg B that in 16 Cyg A, by a factor of at least 4.7. The interest of studying the 16 Cyg system is that the two star have the same age and the same initial composition. The presently observed differences must be due to their different evolution, related to the fact that one of them hosts a planet contrary to the other one. We computed models of the two stars which precisely fit the observed seismic frequencies. We used the Toulouse Geneva Evolution Code (TGEC) that includes complete atomic diffusion (including radiative accelerations). We compared the predicted surface abundances with the spectroscopic observations and confirmed that another mixing process is needed. We then included the effect of accretion-induced fingering convection. The accretion of planetary matter does not change the metal abundances but leads to lithium destruction which depends on the accreted mass. A fraction of earth mass is enough to explain the lithium surface abundances of 16 Cyg B. We also checked the beryllium abundances. In the case of accretion of heavy matter onto stellar surfaces, the accreted heavy elements do not remain in the outer convective zones but they are mixed downwards by fingering convection induced by the unstable $μ$-gradient. Depending on the accreted mass, this mixing process may transport lithium down to its nuclear destruction layers and lead to an extra lithium depletion at the surface. A fraction of earth mass is enough to explain a lithium ratio of 4.7 in the 16 Cyg system. In this case beryllium is not destroyed. Such a process may be frequent in planet host stars and should be studied in other cases in the future.

Τα δεδομένα που πρόκειται να αναλυθούν προέρχονται από  έρευνα ικανοποίησης της εταιρίας Skytrax.
H NCA επικεντρώνεται στην αναγνώριση των απαραίτητων συνθηκών για ένα δεδομένο αποτέλεσμα και αναλύει την παρουσία ή απουσία απαραίτητων συνθηκών για ένα αποτέλεσμα σε αντίθεση  με την fs/QCA, η οποία, στοχεύει στην αναγνώριση συνδυασμών που είναι επαρκείς για ένα αποτέλεσμα και αξιολογεί το βαθμό συμμετοχής των περιπτώσεων στις συνθήκες που οδηγούν σε ένα αποτέλεσμα.
Και οι δύο μέθοδοι έχουν τα πλεονεκτήματα και τα μειονεκτήματα τους. Η NCA είναι κατάλληλη για καταστάσεις όπου υπάρχει μια σαφής θεωρητική κατανόηση των απαραίτητων συνθηκών, που απαιτούνται για ένα αποτέλεσμα. Από την άλλη πλευρά, η fs/QCA είναι πιο κατάλληλη για καταστάσεις όπου δεν υπάρχει μια σαφής θεωρητική κατανόηση των αιτιών και των αποτελεσμάτων. Ωστόσο η fs/QCA είναι πιο πολύπλοκη στην εφαρμογή της και απαιτεί μεγαλύτερο αριθμό παραγόντων για την ανάλυση.

description: This paper reports on a two-part study focusing on automatic metadata maintenance  for NC Health Info, a health information web portal for North Carolina residents. The  first examination is an analysis of web changes and their potential impacts on  metadata quality. The second examination proposes a framework for semi-automatic  metadata maintenance, which builds off of a hierarchy of evaluation proposed by Greenberg (2005). This work is supported by a baseline counting of the average  number of Dublin Core Metadata elements on Dublin Core website and a conceptual  framework enhanced with mathematical Set Theory. The results lead to a model that  enables catalogers to review only a portion of the web resources with detected  changes. The proposed approach aims to benefit the metadata generation and  maintenance by reducing human effort and time consumption while ensuring high  metadata quality.

description: Neutral interstellar helium has been observed by the Interstellar Boundary Explorer (IBEX) since 2009 with a signal-to-noise ratio well above 1000. Because of the geometry of the observations, the signal observed from January to March each year is the easiest to identify. However, as we show via simulations, the portion of the signal in the range of intensities from 10^{-3} to 10^{-2} of the peak value, previously mostly left out from the analysis, may bring important information about the details of the distribution function of interstellar He gas in front of the heliosphere. In particular, these observations may inform us about possible departures of the parent interstellar He population from equilibrium. We compare the expected distribution of the signal for the canonical assumption of a single Maxwell-Boltzmann population with the distributions for a superposition of the Maxwell-Boltzmann primary population and the recently discovered Warm Breeze, and for a single primary population given by a kappa function. We identify the regions on the sky where the differences between those cases are expected to be the most visible against the background. We discuss the diagnostic potential of the fall peak of the interstellar signal, reduced by a factor of 50 due to the Compton-Getting effect but still above the detection limit of IBEX. We point out the strong energy dependence of the fall signal and suggest that searching for this signal in the data could bring an independent assessment of the low-energy measurement threshold of the IBEX-Lo sensor.

description: The separation distribution for M-dwarf binaries in the ASTRALUX survey is narrower and peaking at smaller separations than the distribution for solar-type binaries. This is often interpreted to mean that M-dwarfs constitute a continuous transition from brown dwarfs (BDs) to stars. Here a prediction for the M-dwarf separation distribution is presented, using a dynamical population synthesis (DPS) model in which "star-like" binaries with late-type primaries ($\lesssim1.5 M_{\rm sun}$) follow universal initial distribution functions and are dynamically processed in their birth embedded clusters. A separate "BD-like" population has both its own distribution functions for binaries and initial mass function (IMF), which overlaps in mass with the IMF for stars. Combining these two formation modes results in a peak on top of a wider separation distribution for late M-dwarfs consistent with the late ASTRALUX sample. The DPS separation distribution for early M-dwarfs shows no such peak and is in agreement with the M-dwarfs in Multiples (MinMS) data. We note that the latter survey is potentially in tension with the early ASTRALUX data. Concluding, the ASTRALUX and MinMS data are unable to unambiguously distinguish whether or not BDs are a continuous extension of the stellar IMF. Future observational efforts are needed to fully answer this interesting question. The DPS model predicts that binaries outside the sensitivity range of the ASTRALUX survey remain to be detected. For application to future data, we present a means to observationally measure the overlap of the putative BD-like branch and the stellar branch. We discuss the meaning of universal star formation and distribution functions.

New Hamiltonian constraint operator for loop quantum gravity
Creators: name: Yang, Jinsong

Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)

description: A new symmetric Hamiltonian constraint operator is proposed for loop quantum gravity, which is well defined in the Hilbert space of diffeomorphism invariant states up to non-planar vertices with valence higher than three. It inherits the advantage of the original regularization method, so that its regulated version in the kinematical Hilbert space is diffeomorphism covariant and creates new vertices to the spin networks. The quantum algebra of this Hamiltonian is anomaly-free on shell, and there is less ambiguity in its construction in comparison with the original method. The regularization procedure for this Hamiltonian constraint operator can also be applied to the symmetric model of loop quantum cosmology, which leads to a new quantum dynamics of the cosmological model.

Reachability Oracles for Directed Transmission Graphs

description: Let $P \subset \mathbb{R}^d$ be a set of $n$ points in $d$ dimensions such that each point $p \in P$ has an associated radius $r_p > 0$. The transmission graph $G$ for $P$ is the directed graph with vertex set $P$ such that there is an edge from $p$ to $q$ if and only if $|pq| \leq r_p$, for any $p, q \in P$. A reachability oracle is a data structure that decides for any two vertices $p, q \in G$ whether $G$ has a path from $p$ to $q$. The quality of the oracle is measured by the space requirement $S(n)$, the query time $Q(n)$, and the preprocessing time. For transmission graphs of one-dimensional point sets, we can construct in $O(n \log n)$ time an oracle with $Q(n) = O(1)$ and $S(n) = O(n)$. For planar point sets, the ratio $Ψ$ between the largest and the smallest associated radius turns out to be an important parameter. We present three data structures whose quality depends on $Ψ$: the first works only for $Ψ< \sqrt{3}$ and achieves $Q(n) = O(1)$ with $S(n) = O(n)$ and preprocessing time $O(n\log n)$; the second data structure gives $Q(n) = O(Ψ^3 \sqrt{n})$ and $S(n) = O(Ψ^3 n^{3/2})$; the third data structure is randomized with $Q(n) = O(n^{2/3}\log^{1/3} Ψ\log^{2/3} n)$ and $S(n) = O(n^{5/3}\log^{1/3} Ψ\log^{2/3} n)$ and answers queries correctly with high probability.

Coherent timing of the accreting millisecond pulsar NGC 6440 X-2

description: We study the 205.9 Hz pulsations of the accreting millisecond X-ray pulsar NGC 6440 X-2 across all outbursts observed with the Rossi X-ray Timing Explorer over a period of 800 days. We find the pulsations are highly sinusoidal with a fundamental amplitude of 5%-15% rms and a second harmonic that is only occasionally detected with amplitudes of <2% rms. By connecting the orbital phase across multiple outbursts, we obtain an accurate orbital ephemeris for this source and constrain its 57 min orbital period to sub-ms precision. We do not detect an orbital period derivative to an upper limit of $ | \dot{P} | \leq 8 \times 10^{-11}$ s/s. We investigate the possibility of coherently connecting the pulse phase across all observed outbursts, but find that due to the poorly constrained systematic uncertainties introduced by a flux-dependent bias in the pulse phase, multiple statistically acceptable phase-connected timing solutions exist.

title: Development of a hybrid anti-icing coating with superhydrophobic and electrothermal properties
Creators: name: Sullivan, Andrew G.
Publisher: name: Memorial University of Newfoundland
Year: 2022

description: This work involves the development of a hybrid anti-icing coating. The multi-layered coating consists of an electrothermal heating film and superhydrophobic top coating. The heating film is composed of a thin layer of conductive copper-based epoxy, insulated between layers of a polydimethylsiloxane (PDMS) elastomer. The superhydrophobic coating is based on FAS-13 modified SiO₂ nanoparticles dispersed in a PDMS matrix. The composite coating was applied to a stainless steel substrate by consecutively depositing each layer by spray-coating. The SiO₂/PDMS coating exhibited a static contact angle of 164.3° and contact angle hysteresis of 2.8°, confirming its superhydrophobic properties. The anti-icing properties of the superhydrophobic coating were investigated experimentally inside a cold chamber at -20°C. The ice adhesion strength was reduced from 284 kPa on the untreated substrate to 50 kPa on the superhydrophobic coating, while the droplet freezing time was delayed from 8 seconds to 76 seconds. The heating film demonstrated a fast thermal response and excellent thermal stability. With the maximum surface power density of 3.46 W/cm², the surface temperature of the heating film could be raised to 10°C in just 45 seconds. In simulated spray-icing tests, the hybrid superhydrophobic-heating film achieved complete anti-icing with a minimum surface power density of 0.26 W/cm². Consequently, the superhydrophobic coating was found to reduce the energy required for anti-icing of the heating film by 41%. The hybrid coating was found to be durable and retained its superhydrophobicity after being subjected to repeated icing and de-icing cycles. The results demonstrate that the hybrid coating has potential for practical applications in the marine and offshore industries due to its simple, versatile fabrication process and energy-efficient anti-icing performance.

A search for an excited muon decaying to a muon and two jets in $pp$ collisions at $\sqrt{s}$ = 8 TeV with the ATLAS detector
Creators: name: ATLAS Collaboration
Publisher: name: arXiv
Year: 2016
Subjects: subject: High Energy Physics - Experiment (hep-ex)
subject: FOS: Physical sciences

description: A new search signature for excited leptons is explored. Excited muons are sought in the channel $pp \to μμ^* \to μμ\textrm{ jet jet}$, assuming both the production and decay occur via a contact interaction. The analysis is based on 20.3 fb$^{-1}$ of $pp$ collision data at a centre-of-mass energy of $\sqrt{s}$ = 8 TeV taken with the ATLAS detector at the Large Hadron Collider. No evidence of excited muons is found, and limits are set at the 95% confidence level on the cross section times branching ratio as a function of the excited-muon mass $m_{μ^*}$. For $m_{μ^*}$ between 1.3 TeV and 3.0 TeV, the upper limit on $σB(μ^* \to μq \bar{q}$) is between 0.6 and 1 fb. Limits on $σB$ are converted to lower bounds on the compositeness scale $Λ$. In the limiting case $Λ= m_{μ^*}$, excited muons with a mass below 2.9 TeV are excluded. With the same model assumptions, these limits at larger $μ^*$ masses improve upon previous limits from traditional searches based on the gauge-mediated decay $μ^* \to μγ$.
