description: We perform classical molecular dynamics to investigate the effects of mechanical strain on single-layer black phosphorus nanoresonators at different temperatures. We find that the resonant frequency is highly anisotropic in black phosphorus due to its intrinsic puckered configuration, and that the quality factor in the armchair direction is higher than in the zigzag direction at room temperature. The quality factors are also found to be intrinsically larger than graphene and MoS2 nanoresonators. The quality factors can be increased by more than a factor of two by applying tensile strain, with uniaxial strain in the armchair direction being most effective. However, there is an upper bound for the quality factor increase due to nonlinear effects at large strains, after which the quality factor decreases. The tension induced nonlinear effect is stronger along the zigzag direction, resulting in a smaller maximum strain for quality factor enhancement.

description: We have measured the scattering strength of charged impurities on a semiconducting single-walled carbon nanotube with known chirality. The resistivity of the nanotube is measured as a function of the density of adsorbed potassium atoms, enabling the determination of the resistance added by an individual potassium atom. Holes are scattered 37 times more efficiently than electrons by an adsorbed potassium atom. The determined scattering strength is used to reveal the spatial extent and depth of the scattering potential for potassium, a model Coulomb adsorbate. Our result represents an essential experimental input to understand adsorbate-induced scattering and provides a crucial step for paving the way to rational design of nanotube-based sensors.

description: We use large scale molecular dynamics (MD) simulations to determine the tensile yield mechanism of orthorhombic polyethylene (PE) crystals with finite chains spanning $10^2-10^4$ carbons in length. We find the yield stress $σ_y$ saturates for long chains at 6.3 GPa, agreeing well with experiments. We show chains do not break but always yield by slip, after nucleation of 1D dislocations at chain ends. Dislocations are accurately described by a Frenkel-Kontorova model parametrized by the mechanical properties of an ideal crystal. We compute a dislocation core size $ξ\approx25$Å and determine the high and low strain rate limits of $σ_y$. Our results suggest characterizing the 1D dislocations of polymer crystals as an efficient method for numerically predicting the ultimate tensile strength of aligned fibers.

Year: 2016

description: Statement of problem: Establishing the occlusal plane of the edentulous mouth is challenging but with the accuracy of 3D radiography, the orientation of the occlusal plane can be determined using stable anatomical landmarks. Purpose: The purpose of this study was to determine the location of the occlusal plane in relation to stable, bony anatomical structures. Material and Methods: Stable bony structures were identified and the orientation of the occlusal plane was determined in relation to these landmarks, using CBCT scans. Results: The anterior determinant of occlusal plane is located 29mm (95% CI: 28.3mm to 30.0mm) inferior to the anterior nasal spine (ANS). In relation to the hamular notch-incisal edge (HNI) plane, the occlusal plane forms a 15.5o angle (95% CI: 14.7o to 16.2o). Conclusions: Results from this study will enable dentists and technicians to accurately locate the occlusal plane in a virtual environment without the use of an analog face-bow.

description: Torque magnetization measurements on YBa$_2$Cu$_3$O$_{y}$ (YBCO) at doping $y=6.67$($p=0.12$), in DC fields ($B$) up to 33 T and temperatures down to 4.5 K, show that weak diamagnetism persists above the extrapolated irreversibility field $H_{\rm irr} (T=0) \approx 24$ T. The differential susceptibility $dM/dB$, however, is more rapidly suppressed for $B\gtrsim 16$ T than expected from the properties of the low field superconducting state, and saturates at a low value for fields $B \gtrsim 24$ T. In addition, torque measurements on a $p=0.11$ YBCO crystal in pulsed field up to 65 T and temperatures down to 8 K show similar behaviour, with no additional features at higher fields. We discuss several candidate scenarios to explain these observations: (a) superconductivity survives but is heavily suppressed at high field by competition with CDW order; (b) static superconductivity disappears near 24 T and is followed by a region of fluctuating superconductivity, which causes $dM/dB$ to saturate at high field; (c) the stronger 3D ordered CDW that sets in above 15 T may suppress the normal state spin susceptibility sufficiently to give an apparent diamagnetism of the magnitude observed.

description: Characterised by a surface bound exosphere and localised crustal magnetic fields, the Moon was considered as a passive object when solar wind interacts with it. However, the neutral particle and plasma measurements around the Moon by recent dedicated lunar missions, such as Chandrayaan-1, Kaguya, Chang'E-1, LRO, and ARTEMIS, as well as IBEX have revealed a variety of phenomena around the Moon which results from the interaction with solar wind, such as backscattering of solar wind protons as energetic neutral atoms (ENA) from lunar surface, sputtering of atoms from the lunar surface, formation of a "mini-magnetosphere" around lunar magnetic anomaly regions, as well as several plasma populations around the Moon, including solar wind protons scattered from the lunar surface, from the magnetic anomalies, pick-up ions, protons in lunar wake and more. This paper provides a review of these recent findings and presents the interaction of solar wind with the Moon in a new perspective.

We aren't widget-builders!: nursing, the unionist/professional contention and its consequences for collective identity
Creators: name: Tucker, Tuneka Kharmi
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2012

description: I examine to what extent members of an occupation group share a collective identity, and whether this identity is enough to foster agreement about the utility of unions to the profession. I interviewed nurses at three hospitals about nursing as a field, their careers, their relationships at work and organizational memberships. I uncovered a collective identity created among nurses across workplaces, positions, and levels of education, and I develop a framework for how these symbolic ties are formed. Nurses connect to one another on one or more of four overlapping dimensions: the community (hospital or unit), category (position or title), practice (patient care) or institutional (nursing as a profession) levels. Each nurse identifies most closely to at least one of these dimensions, which connects them to other nurses who they recognize as being part of a collectivity. They enact this collective identity in the way that they describe what being a nurse means. Because each category is not mutually exclusive and nurses may have more than one strong connection to a dimension, a collective identity is formed. I also found that collective identity is not sufficient to bring about solidarity for any group, that is that solidarity and collective identity are distinct. My research makes new contributions to the sociological literature on the mechanisms of collective identity and solidarity, professional work, and organizational and institutional solidarity. Its broader impacts are largely to nursing scholarship and policy. As the population ages, healthcare policy changes, and nursing continues to gain legitimacy as a profession, many of the workplace dynamics that I uncovered will become increasingly important to consider as hospitals try to recruit and retain nurses.

Various aspects of the Deformation Dependent Mass model of nuclear structure

description: Recently, a variant of the Bohr Hamiltonian was proposed where the mass term is allowed to depend on the beta variable of nuclear deformation. Analytic solutions of this modified Hamiltonian have been obtained using the Davidson and the Kratzer potentials, by employing techniques from supersymmetric quantum mechanics. Apart from the new set of analytic solutions, the newly introduced Deformation-Dependent Mass (DDM) model offered a remedy to the problematic behaviour of the moment of inertia in the Bohr Hamiltonian, where it appears to increase proportionally to the square of beta. In the DDM model the moments of inertia increase at a much lower rate, in agreement with experimental data. The current work presents an application of the DDM-model suitable for the description of nuclei at the point of shape/phase transitions between vibrational and gamma-unstable or prolate deformed nuclei and is based on a method that was successfully applied before in the context of critical point symmetries.

description: Tidal disruption has a dramatic impact on the outcome of neutron star-black hole mergers. The phenomenology of these systems can be divided in three classes: nondisruptive, mildly disruptive or disruptive. The cutoff frequency of the gravitational radiation produced during the merger (which is potentially measurable by interferometric detectors) is very different in each regime, and when the merger is disuptive it carries information on the neutron star equation of state. Here we use semianalytical tools to derive a formula for the critical binary mass ratio $Q=M_{\rm BH}/M_{\rm NS}$ below which mergers are disruptive as a function of the stellar compactness $\mathcal{C}=M_{\rm NS}/R_{\rm NS}$ and the dimensionless black hole spin $χ$. We then employ a new gravitational waveform amplitude model, calibrated to $134$ general relativistic numerical simulations of binaries with black hole spin (anti-)aligned with the orbital angular momentum, to obtain a fit to the gravitational-wave cutoff frequency in the disruptive regime as a function of $\mathcal{C}$, $Q$ and $χ$. Our findings are important to build gravitational wave template banks, to determine whether neutron star-black hole mergers can emit electromagnetic radiation (thus helping multimessenger searches), and to improve event rate calculations for these systems.

description: We present results from a numerical study of particle dispersion in the weakly nonlinear regime of Rayleigh-Bénard convection of a fluid with Prandtl number around unity, where bi-stability between ideal straight convection rolls and weak turbulence in the form of Spiral Defect Chaos exists. While Lagrangian pair statistics has become a common tool for studying fully developed turbulent flows at high Reynolds numbers, we show that key characteristics of mass transport can also be found in convection systems that show no or weak turbulence. Specifically, for short times, we find Richardson-like $t^3$ scaling of pair dispersion. We explain our findings quantitatively with a model that captures the interplay of advection and diffusion. For long times we observe diffusion-like dispersion of particles that becomes independent of the individual particles' stochastic movements. The spreading rate is found to depend on the degree of spatio-temporal chaos.

description: We present an architectural Capability Speculation Contract (CSC) for CHERI implementations, test for violations in the CHERI-Toooba microarchitecture, and develop and evaluate a conforming implementation. The CHERI capability instruction-set extension promises proven architectural guarantees for memory safety and pointer provenance. However, superscalar and out-of-order CHERI implementations will need to contend with microarchitectural transient-execution side-channel attacks. To ensure the safety of all CHERI implementations, we articulate CSC: a universal architectural speculation contract for the CHERI architecture that maintains key capability invariants in speculation. We then develop tests against sub-classes of CSC, and discover violations in CHERI-Toooba that lead to a new class of transient-execution attacks, Meltdown-CF (Capability Forgery) for which we develop a user-mode exploit that allows reads of secret data. We then develop strategies to fully enforce CSC in CHERI-Toooba. We find that simplistic, strong enforcement incurs a low performance overhead of only 3.43% in SPECint2006 benchmarks, with promise for more optimal designs in the future. Our architectural recommendations to mitigate Meltdown-CF have been accepted by the upstream CHERI architecture and are included in current CHERI-RISC-V drafts for ratification.

description: The ancient geographic coordinates given for places of Great Britain in Ptolemy's Geographike Hyphegesis are investigated by means of geodetic methods. The turning of Scotland to the east is modelled by a three-dimensional rotation. On the basis of different data sets of control points, the parameters of the rotation are estimated by means of methods of adjustment theory. Furthermore, a geodetic-statistical analysis method is applied to Scotland, by which groups of places of homogenous distortions and modern counterparts of the ancient places are determined. Based on the results of the investigations, answers are given for questions concerning Ptolemaic positions unsolved so far.

description: Using a variant of the Euler–Maruyama scheme for stochastic functional differential equations with bounded memory driven by Brownian motion we show that only weak one-sided local Lipschitz (or “monotonicity”) conditions are sufficient for local existence and uniqueness of strong solutions. In case of explosion the method yields the maximal solution up to the explosion time. We also provide a weak growth condition which prevents explosions to occur. In an appendix we formulate and prove four lemmas which may be of independent interest: three of them can be viewed as rather general stochastic versions of Gronwall's Lemma, the final one provides tail bounds for Hölder norms of stochastic integrals.

description: Filaments represent a key structure during the early stages of the star formation process. Simulations show filamentary structure commonly formed before and during the formation of cores. Aims. The Serpens Core represents an ideal laboratory to test the state-of-the-art of simulations of turbulent Giant Molecular Clouds. We use Herschel observations of the Serpens Core to compute temperature and column density maps of the region. Among the simulations of Dale et al. (2012), we select the early stages of their Run I, before stellar feedback is initiated, with similar total mass and physical size as the Serpens Core. We derive temperature and column density maps also from the simulations. The observed distribution of column densities of the filaments has been analysed first including and then masking the cores. The same analysis has been performed on the simulations as well. A radial network of filaments has been detected in the Serpens Core. The analysed simulation shows a striking morphological resemblance to the observed structures. The column density distribution of simulated filaments without cores shows only a log-normal distribution, while the observed filaments show a power-law tail. The power-law tail becomes evident in the simulation if one focuses just on the column density distribution of the cores. In contrast, the observed cores show a flat distribution. Even though the simulated and observed filaments are subjectively similar-looking, we find that they behave in very different ways. The simulated filaments are turbulence-dominated regions, the observed filaments are instead self-gravitating structures that will probably fragment into cores.

description: We prove the existence of a computable function f∶ℕ→ℕ such that for every integer k and every digraph D, either D contains a collection C of k directed cycles of even length such that no vertex of D belongs to more than four cycles in C, or there exists a set S⊆ V(D) of size at most f(k) such that D−S has no directed cycle of even length. Moreover, we provide an algorithm that finds one of the two outcomes of this statement in time g(k)nO(1) for some computable function g∶ ℕ→ℕ. Our result unites two deep fields of research from the algorithmic theory for digraphs: The study of the Erdős-Pósa property of digraphs and the study of the Even Dicycle Problem. The latter is the decision problem which asks if a given digraph contains an even dicycle and can be traced back to a question of Pólya from 1913. It remained open until a polynomial time algorithm was finally found by Robertson, Seymour, and Thomas (Ann. of Math. (2) 1999) and, independently, McCuaig (Electron. J. Combin. 2004; announced jointly at STOC 1997). The Even Dicycle Problem is equivalent to the recognition problem of Pfaffian bipartite graphs and has applications even beyond discrete mathematics and theoretical computer science. On the other hand, Younger’s Conjecture (1973), states that dicycles have the Erdős-Pósa property. The conjecture was proven more than two decades later by Reed, Robertson, Seymour, and Thomas (Combinatorica 1996) and opened the path for structural digraph theory as well as the algorithmic study of the directed feedback vertex set problem. Our approach builds upon the techniques used to resolve both problems and combines them into a powerful structural theorem that yields further algorithmic applications for other prominent problems.

The pollution arising from the positive--to--positive, and positive to negative parity baryons are eliminated by constructing the sum rules for different Lorentz structures. Nonzero value of the considered magnetic moment can be attributed to the violation of the $SU(3)$ symmetry.

description: We report on a numerical experiment performed to analyze fluctuations of the entropy production in turbulent thermal convection, a physical configuration that represents here a prototypical case of an out-of-equilibrium dissipative system. We estimate the entropy production from instantaneous measurements of the local temperature and velocity fields sampled along the trajectory of a large number of point-wise Lagrangian tracers. The entropy production is characterized by large fluctuations and becomes often negative. This represents a sort of "finite-time" violation of the second principle of thermodynamics, since the direction of the energy flux is opposite to that prescribed by the external gradient. We clearly show that the fluctuations of entropy production observed in the present system verify the fluctuation relation (FR), even though the system is time-irreversible.

description: Using an advanced version of the hadron resonance gas model we have found several remarkable irregularities at chemical freeze-out. The most prominent of them are two sets of highly correlated quasi-plateaus in the collision energy dependence of the entropy per baryon, total pion number per baryon, and thermal pion number per baryon which we found at center of mass energies 3.6-4.9 GeV and 7.6-10 GeV. The low energy set of quasi-plateaus was predicted a long time ago. On the basis of the generalized shock-adiabat model we demonstrate that the low energy correlated quasi-plateaus give evidence for the anomalous thermodynamic properties of the mixed phase at its boundary to the quark-gluon plasma. The question is whether the high energy correlated quasi-plateaus are also related to some kind of mixed phase. In order to answer this question we employ the results of a systematic meta-analysis of the quality of data description of 10 existing event generators of nucleus-nucleus collisions in the range of center of mass collision energies from 3.1 GeV to 17.3 GeV. These generators are divided into two groups: the first group includes the generators which account for the quark-gluon plasma formation during nuclear collisions, while the second group includes the generators which do not assume the quark-gluon plasma formation in such collisions. Comparing the quality of data description of more than a hundred of different data sets of strange hadrons by these two groups of generators, we find two regions of the equal quality of data description which are located at the center of mass collision energies 4.3-4.9 GeV and 10.-13.5 GeV. These two regions of equal quality of data description we interpret as regions of the hadron-quark-gluon mixed phase formation.

description: Using 7 years of data from the Helium, Oxygen, Proton, and Electron instrument on the Van Allen Probes, equatorial pitch angle distributions (PADs) of 1-50 keV electrons in Earth's inner magnetosphere are investigated statistically. An empirical model of electron equatorial PADs as a function of radial distance, magnetic local time, geomagnetic activity, and electron energy is constructed using the method of Legendre polynomial fitting. Model results show that most equatorial PADs of 1-10s of keV electrons in Earth's inner magnetosphere are pancake PADs, and the lack of butterfly PADs is likely due to their relatively flat or positive flux radial gradients at higher altitudes. During geomagnetically quiet times, more anisotropic distributions of 1-10s of keV electrons at dayside than nightside are observed, which could be responsible for moderate chorus wave activities at dayside during quiet times as reported by previous studies. During active times, the anisotropy of 1-10s of keV electrons significantly enhances, consistent with the enhanced chorus wave activity during active times and suggesting the critical role of 1-10s of keV electrons in generating chorus waves in Earth's inner magnetosphere. Different enhanced anisotropy patterns of different energy electrons are also observed during active times: at R > similar to 4 R-E, keV electrons are more anisotropic at dawn to noon, while 10s of keV electrons have larger anisotropy at midnight to dawn. These differences, combined with the statistical distribution of chorus waves shown in previous studies, suggest the differential roles of electrons with different energies in generating chorus waves with different properties.

The effects of sucrose abstinence on motivated responding and nucleus accumbens cellular signaling
Creators: name: Jones, Joshua Lacey

Year: 2007

description: A critical feature of cocaine addiction is the strong propensity to relapse following periods of abstinence. Here, we examined whether abstinence from sucrose self-administration in rats altered behavioral responding and nucleus accumbens (NAc) cell firing in a manner similar to that observed following cocaine abstinence. Rats were trained to self-administer sucrose, and then underwent either a 0, 7 or 30 day period of abstinence. Electrophysiological recording procedures were used to examine NAc activity during resumption of sucrose self-administration. Results showed no increase in sucrose-seeking or changes in cell firing of NAc neurons following any abstinence period. Furthermore, in a separate group of animals trained under identical conditions, motivated responding was assessed during extinction and cue-induced reinstatement tasks. No evidence was obtained for any alterations in sucrose-seeking across abstinence conditions. Taken together, these results provide insight about the neural circuitry of natural and drug rewards, and relapse behavior.

Masses of $D$ mesons, $D_s$ mesons and charmonium states from twisted mass lattice QCD

description: We compute masses of $D$ mesons, $D_s$ mesons and charmonium states using Wilson twisted mass lattice QCD. We present results for spin $J = 0,1,2,3$, parity $\mathcal{P} = -,+$ and in case of charmonium also charge conjugation $\mathcal{C} = -,+$. Computations are based on quark-antiquark creation operators and performed at three different unphysically heavy $u/d$ quark masses allowing an extrapolation to the physical $u/d$ quark mass. Within combined statistical and systematic errors, which are around $2 \% \ldots 3 \%$, our results agree with available experimental results. Particular focus is put on the $J^\mathcal{P} = 1^+$ mesons $D_1(2430)$ and $D_1(2420)$. We separate and classify these close-by states according to the total angular momentum of their light degrees of freedom, $j \approx 1/2$ and $j \approx 3/2$. This is a first important step to study decays $B^{(\ast)} \rightarrow D_1 + l + ν$, for which a long-standing conflict between theory and experiment exists.

description: Rising-tone chorus waves have already been successfully produced in a mirror magnetic field with the use of one- and two-dimensional particle-in-cell (PIC) simulations. However, in reality, the background magnetic field in the inner Earth's magnetosphere is a dipole magnetic field, unlike symmetric mirror fields. In this paper, with the two-dimensional (2-D) general curvilinear PIC (gcPIC) code, we investigate the generation of rising-tone chorus waves in the dipole magnetic field configuration. The plasma consists of three components: immobile ions, cold background, and hot electrons. In order to save computational resource, the topology of the magnetic field is roughly equal to that at L = 0.6 R-E, although the plasma parameters corresponding to those at L = 6 R-E (R-E is the Earth's radius) are used. Whistler mode waves are first excited around the magnetic equator by the hot electrons with a temperature anisotropy. The excited whistler mode waves propagate almost parallel and antiparallel to the background magnetic field in their source region, which is limited at vertical bar lambda vertical bar <= 3 degrees (where lambda is the magnetic latitude). When the waves leave from the source region and propagate toward high latitudes, both their amplitude and wave normal angle become larger. However, the group velocity of the waves is directed toward high latitudes almost along the magnetic field. During such a process, the waves have a frequency chirping, as shown by a rising tone in the frequency-time spectrogram. To our best knowledge, it is for the first time that rising-tone chorus are generated in a dipole magnetic field with a PIC simulation.
