description: Strain fields, dislocations and defects may be used to control electronic properties of graphene. By using advanced imaging techniques with high-resolution transmission electron microscopes, we have measured the strain and rotation fields about dislocations in monolayer graphene with single-atom sensitivity. These fields differ qualitatively from those given by conventional linear elasticity. However, atom positions calculated from two dimensional (2D) discrete elasticity and three dimensional discrete periodized Föppl-von Kármán equations (dpFvKEs) yield fields close to experiments when determined by geometric phase analysis. 2D theories produce symmetric fields whereas those from experiments exhibit asymmetries. Numerical solutions of dpFvKEs provide strain and rotation fields of dislocation dipoles and pairs that also exhibit asymmetries and, compared with experiments, may yield information on out-of-plane displacements of atoms. While discrete theories need to be solved numerically, analytical formulas for strains and rotation about dislocations can be obtained from 2D Mindlin's hyperstress theory. These formulas are very useful for fitting experimental data and provide a template to ascertain the importance of nonlinear and nonplanar effects. Measuring the parameters of this theory, we find two characteristic lengths between three and four times the lattice spacings that control dilatation and rotation about a dislocation. At larger distances from the dislocation core, the elastic fields decay to those of conventional elasticity. Our results may be relevant for strain engineering in graphene and other 2D materials of current interest.

description: We present results on the renormalization functions of the quark field and fermion bilinears with up to one covariant derivative. For the fermion part of the action we employ the twisted mass formulation with $N_f{=}2$ and $N_f{=}4$ degenerate dynamical quarks, while in the gluon sector we use the Iwasaki improved action. The simulations for $N_f{=}4$ have been performed for pion masses in the range of 390MeV - 760MeV and at three values of the lattice spacing, $a$, corresponding to $β{=}1.90,\,1.95,\,2.10$. The $N_f{=}2$ action includes a clover term with $c_{\rm sw}{=}1.57551$ at $β{=}2.10$, and three ensembles at different values of $m_π$. The evaluation of the renormalization functions is carried out in the RI$'$ scheme using a momentum source. The non-perturbartive evaluation is complemented with a perturbative computation, which is carried out at one-loop level and to all orders in the lattice spacing, $a$. For each renormalization function computed non-perturbatively we subtract the corresponding lattice artifacts to all orders in $a$, so that a large part of the cut-off effects is eliminated. The renormalization functions are converted to the ${\overline{\rm MS}}$ scheme at a reference energy scale of $μ{=}2$ GeV after taking the chiral limit.

description: We present an X-ray analysis on the Galactic supernova remnant (SNR) G298.6-0.0 with Suzaku. The X-ray image shows a center-filled structure inside the radio shell, implying this SNR is categorized as a mixed-morphology (MM) SNR. The spectrum is well reproduced by a single temperature plasma model in ionization equilibrium, with a temperature of 0.78 (0.70-0.87) keV. The total plasma mass of 30 solar mass indicates that the plasma has interstellar medium origin. The association with a GeV gamma-ray source 3FGL J1214.0-6236 on the shell of the SNR is discussed, in comparison with other MM SNRs with GeV gamma-ray associations. It is found that the flux ratio between absorption-corrected thermal X-rays and GeV gamma-rays decreases as the MM SNRs evolve to larger physical sizes. The absorption-corrected X-ray flux of G298.6-0.0 and the GeV gamma-ray flux of 3FGL J1214.0-6236 closely follow this trend, implying that 3FGL J1214.0-6236 is likely to be the GeV counterpart of G298.6-0.0.

The contribution of the biceps brachii on glenohumeral muscle activation
Creators: name: Lisowski, James Karol
Publisher: name: University of North Carolina at Chapel Hill
Year: 2011

description: The long head of the biceps brachii tendon is subject to extreme amounts of compressive and tensile forces during overhead activities. As a result of these forces, a variety of pathological conditions can occur. It is unclear whether these conditions are a result of the biceps serving an active or passive role at the glenohumeral joint. Though previous research has attempted to determine the role of the biceps, disparities exist in the findings. The active contribution of the biceps can be determined by comparing shoulder muscle activation at varying elevation arcs pre and post biceps fatigue. These results can aid in the discussion about the appropriateness of common surgical techniques performed. A mixed model ANOVA was run to compare the muscle activities during the various humeral elevation arcs pre and post biceps fatigue protocol. The study found no significant changes in EMG activity between pre and post fatigue muscle activation.
Effects of headache on clinical measures of neuropsychological function and postural stability

Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2006

description: Our purpose was to compare the recovery patterns of athletes reporting headache at baseline (PAH) and athletes reporting posttraumatic headache (PTH) following concussion. The study involved two separate analyses of concussed high school and collegiate athletes classified based on baseline headache scores and another by headache scores at twenty-four hours postinjury. All subjects completed a graded symptom checklist. A subset of subjects completed the Standardized Assessment of Concussion (SAC) and the Balance Error Scoring System (BESS) at baseline and days one, three, and seven post-injury. A smaller subset completed ANAM at a sub-acute session (1-2 days post-injury) and a prolonged session (5-7 days postinjury). Significant differences in symptomatology and mental status (p<.05) were observed for PAH and PTH. Differences were also observed in balance and neuropsychological performance scores regarding PTH. (p<.05) Results suggest that headache scores (PAH and PTH) should be considered in the interpretation of clinical measures of concussion.
Autocratic strategies for alternating games

Subjects: subject: Populations and Evolution (q-bio.PE)
subject: FOS: Biological sciences

description: Repeated games have a long tradition in the behavioral sciences and evolutionary biology. Recently, strategies were discovered that permit an unprecedented level of control over repeated interactions by enabling a player to unilaterally enforce linear constraints on payoffs. Here, we extend this theory of "zero-determinant" (or, more generally, "autocratic") strategies to alternating games, which are often biologically more relevant than traditional synchronous games. Alternating games naturally result in asymmetries between players because the first move matters or because players might not move with equal probabilities. In a strictly-alternating game with two players, $X$ and $Y$, we give conditions for the existence of autocratic strategies for player $X$ when (i) $X$ moves first and (ii) $Y$ moves first. Furthermore, we show that autocratic strategies exist even for (iii) games with randomly-alternating moves. Particularly important categories of autocratic strategies are extortionate and generous strategies, which enforce unfavorable and favorable outcomes for the opponent, respectively. We illustrate these strategies using the continuous Donation Game, in which a player pays a cost to provide a benefit to the opponent according to a continuous cooperative investment level. Asymmetries due to alternating moves could easily arise from dominance hierarchies, and we show that they can endow subordinate players with more autocratic strategies than dominant players.

Russian Military Basing in the Black Sea and Eastern Mediterranean: The Central Component to the Regional Foreign Policy
Creators: name: Cayce, Taylor
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2016

description: In the last eight years, Russia has sent troops into Georgia, Ukraine, and Syria to further its foreign policy. This thesis describes this policy and how regional military bases fit into them. Defending these bases and maintaining Russian control over them is the impetus for military action in Russian foreign policy governing the Black Sea and Eastern Mediterranean. I contrast this understanding of why Russia has acted in these conflicts with three competing theories of Russian foreign policy and explain why they fail to explain all three of the conflicts.
The effect of estradiol on IL-6 concentration in response to an acute bout of exercise
Creators: name: Koltun, Kristen
Publisher: name: University of North Carolina at Chapel Hill
Year: 2012

description: This study attempted to find the effect of differing estradiol (E2) concentrations on the IL-6 response to an acute bout of exercise. Ten eumenorrheic women (n=10) who were not using oral contraceptives completed two 60 minute running sessions at 61% VO2 peak, once during the follicular phase (low E2) and once during the luteal phase (high E2) of the menstrual cycle. Resting, immediately post exercise, and 30 minute recovery blood samples were assessed for IL-6. Resting E2 concentrations confirmed the appropriate hormonal status for each experimental session. Neither the absolute concentration of IL-6 nor the percent change in IL-6 from rest was significantly different between phases (main effect and interaction effect; responses approached significance; p=0.07). In conclusion, there is no relationship between E2 and IL-6 in response to exercise; although IL-6 trends towards being lower with high E2 concentration. Based on this, it cannot be suggested that female athletes should alter training levels based on hormonal status, however, additional research is necessary as this study was underpowered (β=0.73).
The local structure factor near an interface; Beyond extended Capillary-Wave models

description: We investigate the local structure factor $S(z;q)$ at a free liquid-gas interface in systems with short-ranged intermolecular forces and determine the corrections to the leading-order, capillary-wave-like, Goldstone mode divergence of $S(z;q)$ known to occur for parallel wavevectors $q\to 0$. We show from explicit solution of the inhomogeneous Ornstein-Zernike equation that for distances $z$ far from the interface, where the profile decays exponentially, $S(z;q)$ splits unambiguously into bulk and interfacial contributions. On each side of the interface, the interfacial contributions can be characterised by distinct liquid and gas wavevector dependent surface tensions, $σ_l(q)$ and $σ_g(q)$, which are determined solely by the $bulk$ two-body and three-body direct correlation functions. At high temperatures, the wavevector dependence simplifies and is determined almost entirely by the appropriate bulk structure factor, leading to positive rigidity coefficients. Our predictions are confirmed by explicit calculation of $S(z;q)$ within square-gradient theory and the Sullivan model. The results for the latter predict a striking temperature dependence for $σ_l(q)$ and $σ_g(q)$, and have implications for fluctuation effects. Our results account quantitatively for the findings of a recent very extensive simulation study by Höfling and Dietrich of the total structure factor in the interfacial region, in a system with a cut-off Lennard-Jones potential, in sharp contrast to extended Capillary-Wave models which failed completely to describe the simulation results.

description: We propose a multireference linearized coupled cluster theory using matrix product states (MPS-LCC) which provides remarkably accurate ground-state energies, at a computational cost that has the same scaling as multireference configuration interaction singles and doubles (MRCISD), for a wide variety of electronic Hamiltonians. These range from first-row dimers at equilibrium and stretched geometries, to highly multireference systems such as the chromium dimer and lattice models such as periodic two-dimensional 1-band and 3-band Hubbard models. The MPS-LCC theory shows a speed up of several orders of magnitude over the usual DMRG algorithm while delivering energies in excellent agreement with converged DMRG calculations. Also, in all the benchmark calculations presented here MPS-LCC outperformed the commonly used multi-reference quantum chemistry methods in some cases giving energies in excess of an order of magnitude more accurate. As a size-extensive method that can treat large active spaces, MPS-LCC opens up the use of multireference quantum chemical techniques in strongly-correlated \emph{ab-initio} Hamiltonians, including two and three-dimensional solids.

Year: 2006

description: The purpose of the research project was to determine the number of United States (U.S.) dental hygiene (DH) programs having full-time (FT) faculty members who provide direct patient care. A pilot-tested questionnaire was placed on Survey Monkey, a survey website. Two-hundred and seventy-eight U.S. DH program directors received two E-mails requesting their participation. A response rate of 69.1% was achieved and showed that 14.2% of the programs required FT faculty members to provide direct patient care while 67.0% of the programs had faculty members who participated. The majority (95.4%) of directors indicated maintaining clinical skills and current clinical techniques as advantages of faculty participation in direct patient care, while 48% of directors indicated participation takes time away from being an educator. Overall, the majority of DH programs did not require FT faculty members to participate in direct patient care; however, over half of the programs had faculty members who participated.

description: More than a dozen wireless technologies are used by air traffic communication systems during different flight phases. From a conceptual perspective, all of them are insecure as security was never part of their design. Recent contributions from academic and hacking communities have exploited this inherent vulnerability to demonstrate attacks on some of these technologies. However, not all of these contributions have resonated widely within aviation circles. At the same time, the security community lacks certain aviation domain knowledge, preventing aviation authorities from giving credence to their findings. In this paper, we aim to reconcile the view of the security community and the perspective of aviation professionals concerning the safety of air traffic communication technologies. To achieve this, we first provide a systematization of the applications of wireless technologies upon which civil aviation relies. Based on these applications, we comprehensively analyze vulnerabilities, attacks, and countermeasures. We categorize the existing research on countermeasures into approaches that are applicable in the short term and research of secure new technologies deployable in the long term. Since not all of the required aviation knowledge is codified in academic publications, we additionally examine existing aviation standards and survey 242 international aviation experts. Besides their domain knowledge, we also analyze the awareness of members of the aviation community concerning the security of wireless systems and collect their expert opinions on the potential impact of concrete attack scenarios using these technologies.

3D Cephalometric Analysis of Bone Anchored Maxillary Protraction in Growing Class III Patients
Creators: name: Beville, Jocelyn M.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2012

description: OBJECTIVES: To evaluate the treatment changes produced by bone anchored maxillary protraction (BAMP) on growing Class III patients using 3D cephalometric measurements. METHODS: CBCT scans were taken before and after treatment on 30 consecutive patients. Dolphin Imaging software was used to calculate linear, angular, and airway measurements. The intraclass correlation coefficient was used to test landmark reliability. One-sample t-tests and Pearson correlations were used to evaluate the treatment changes. RESULTS: The maxillary bone orthopedic effects are coupled with forward growth and response to treatment at zygomatic landmarks. Mandibular changes showed statistically significant closure of the mandibular plane angle bilaterally. Although this study sample presented significant mandibular growth restraint, the airway volume with growth and treatment was significantly increased. CONCLUSIONS: Short term assessment of 3D cephalometric changes with BAMP clearly demonstrated a combination of different skeletal components of midface protraction and mandibular growth restraint without negative effects on airway dimensions.

description: This paper analyzes Libor interest rates for seven different maturities and referred to operations in British Pounds, Euro, Swiss Francs and Japanese Yen, during the period years 2001 to 2015. The analysis is performed by means of two quantifiers derived from Information Theory: the permutation Shannon entropy and the permutation Fisher information measure. An anomalous behavior in the Libor is detected in all currencies except Euro during the years 2006--2012. The stochastic switch is more severe in 1, 2 and 3 months maturities. Given the special mechanism of Libor setting, we conjecture that the behavior could have been produced by the manipulation that was uncovered by financial authorities. We argue that our methodology is pertinent as a market overseeing instrument.

Puzzling over Imaginative Resistance

description: On one way of understanding things, philosophical puzzles are divisible into three broad classes. The first class are easy to understand, but difficult to solve. The second class are difficult to understand, but coming to understand them places us far down the path of solving them. The third class are difficult to understand, and, even once understood, difficult to solve. The puzzle that this essay will be concerned with falls into the last of these classes. Tamar Gendler calls this puzzle the “puzzle of imaginative resistance.” This essay will be aimed at understanding the puzzle, and at making some progress towards solving it. The second of these aims will largely involve evaluating Gendler’s treatment of the puzzle, and attempting to draw some lessons from that evaluation. Gendler’s first and most direct treatment of the puzzle can be found in her essay, “The Puzzle of Imaginative Resistance.” That essay has three primary aims: i) to characterize the puzzle of imaginative resistance, ii) to argue that one natural solution to the puzzle is unsuccessful, and iii) to present her own solution to the puzzle. In what follows, I will be arguing that Gendler does not quite achieve her second and third aims.

description: We present a theory of the electronic and optical properties of a charged artificial benzene ring (ABR). The ABR is described by the extended Hubbard model solved using exact diagonalization methods in both real and Fourier space as a function of tunneling matrix element t, Hubbard on-site repulsion U and inter-dot interaction V. In the strongly interacting case we present exact analytical results for the spectrum of the hole in a half-filled ABR dressed by spin excitations of remaining electrons. The spectrum is interpreted in terms of the appearance of a topological phase associated with an effective gauge field piercing through the ring. We show that the maximally spin polarized (S=5/2) and maximally spin depolarised (S=1/2) states are the lowest energy, orbitally non degenerate, states. We discuss the evolution of the phase diagram and level crossings as interactions are switched off and the ground state becomes spin non-degenerate but orbitally degenerate S=1/2. We present a theory of optical absorption spectra and show that the evolution of the ground and excited states, level crossings and presence of artificial gauge can be detected optically.

description: The main goal of this study was to further explore the hypothesis that experience-dependent neural network activity and neurotransmission can modulate adult OPC proliferation and differentiation. More specifically, we used stereology to establish whether extensive reference memory training and system-wide administration of GABAergic agonists and antagonists could influence the proliferation and differentiation of adult OPCs, as well as the prevalence of OPC-neuron pairs. Analysis of the effects of reference memory training on OPC proliferation and differentiation corresponds to experiment 2, analysis of the effects of GABAergic agents on OPC proliferation and differentiation corresponds to experiment 3, and analysis of the effects of both reference memory training and GABAergic agents on OPC-neuron pairs, as well as an histological analysis of these closely apposed cells, corresponds to experiment 4.

description: We present a method of selection of 24~$μ$m galaxies from the AKARI North Ecliptic Pole (NEP) Deep Field down to $150 \mbox{ }μ$Jy and measurements of their two-point correlation function. We aim to associate various 24 $μ$m selected galaxy populations with present day galaxies and to investigate the impact of their environment on the direction of their subsequent evolution. We discuss using of Support Vector Machines (SVM) algorithm applied to infrared photometric data to perform star-galaxy separation, in which we achieve an accuracy higher than 80\%. The photometric redshift information, obtained through the CIGALE code, is used to explore the redshift dependence of the correlation function parameter ($r_{0}$) as well as the linear bias evolution. This parameter relates galaxy distribution to the one of the underlying dark matter. We connect the investigated sources to their potential local descendants through a simplified model of the clustering evolution without interactions. We observe two different populations of star-forming galaxies, at $z_{med}\sim 0.25$, $z_{med}\sim 0.9$. Measurements of total infrared luminosities ($L_{TIR}$) show that the sample at $z_{med}\sim 0.25$ is composed mostly of local star-forming galaxies, while the sample at $z_{med}\sim0.9$ is composed of luminous infrared galaxies (LIRGs) with $L_{TIR}\sim 10^{11.62}L_{\odot}$. We find that dark halo mass is not necessarily correlated with the $L_{TIR}$: for subsamples with $L_{TIR}= 10^{11.15} L_{\odot}$ at $z_{med}\sim 0.7$ we observe a higher clustering length ($r_{0}=6.21\pm0.78$ $[h^{-1} \mbox{Mpc}]$) than for a subsample with mean $L_{TIR}=10^{11.84} L_{\odot}$ at $z_{med}\sim1.1$ ($r_{0}=5.86\pm0.69$ $h^{-1} \mbox{Mpc}$). We find that galaxies at $z_{med}\sim 0.9$ can be ancestors of present day $L_{*}$ early type galaxies, which exhibit a very high $r_{0}\sim 8$~$h^{-1} \mbox{Mpc}$.

description: Objective: The study was conducted to evaluate the dental erosion potential of commercial bottled water, well water, and vegetable juice by pH-metric titration. Method: 13 bottled water brands, well water from 15 locations, and 9 vegetable juice brands were tested for pH value and titratable acidity (TA). Palatability test and questionnaire survey were performed for bottled water. Result: 6 bottled and 6 well waters had pH lower or close to critical pH of dentin (6.7) and enamel (5.2-5.5), while all vegetable juices showed low pH (4.0-4.3). Their TA value ranges were 1-14μL, 20-103μL, and 33.9-81.7mL of 0.1M NaOH, respectively. No significant differences were found in taste preferences for bottled water. Conclusion: Marked low pH and high TA of all vegetable juice brands indicate significant potential for dental erosion compared to bottled and well waters, and can compromise dental health with long term exposure.

description: We use the observed unresolved cosmic X-ray background (CXRB) in the 0.5-2 keV band and existing upper limits on the 21-cm power spectrum to constrain the high-redshift population of X-ray sources, focusing on their effect on the thermal history of the Universe and the cosmic 21-cm signal. Because the properties of these sources are poorly constrained, we consider hot gas, X-ray binaries and mini-quasars (i.e., sources with soft or hard X-ray spectra) as possible candidates. We find that (1) the soft-band CXRB sets an upper limit on the X-ray efficiency of sources that existed before the end of reionization, which is one-to-two orders of magnitude higher than typically assumed efficiencies, (2) hard sources are more effective in generating the CXRB than the soft ones, (3) the commonly-assumed limit of saturated heating is not valid during the first half of reionization in the case of hard sources, with any allowed value of X-ray efficiency, (4) the maximal allowed X-ray efficiency sets a lower limit on the depth of the absorption trough in the global 21-cm signal and an upper limit on the height of the emission peak, while in the 21-cm power spectrum it sets a minimum amplitude and frequency for the high-redshift peaks, and (5) the existing upper limit on the 21-cm power spectrum sets a lower limit on the X-ray efficiency for each model. When combined with the 21-cm global signal, the CXRB will be useful for breaking degeneracies and helping constrain the nature of high-redshift heating sources.

description: People’s attention cannot help being affected by what others are looking at. The dot-perspective task has been devised to investigate this "Reflective Shift of Attention" phenomenon. The task consists of trials in which virtual scenes with an avatar facing some targets are presented. Participants have to judge as quick as possible how many targets they can see. Typically, this task shows an interference pattern with participants recording slower RTs and more errors when the avatar is facing away from the targets. Two accounts have been advanced to explain this interference. The mentalizing account focuses on the “social relevance” of the avatar; whilst the domain-general account focuses on the directional features of the avatar. To investigate their relative contribution, we developed an avatar with isolated social features and compared its effects with an avatar having social and directional features conjugated. Results showed that whilst the avatar with conjugated features generates interference, the avatar with isolated social features, generates interference only when considering the errors but not the RTs. To interpret these results, we suggest that RTs and errors underpin two different processes: RTs underpin orientating processes whilst errors underpin decisional processes. The formers are sensitive to the directional features of the other while the latter are sensitive to its social features as well as its directional features. We conclude in favour of an integrated approach: attention is firstly reflexively orientated by the directional features of the others; it is then modulated by the others' social features.

description: It is demonstrated how to generate time series with tailored nonlinearities by inducing well- defined constraints on the Fourier phases. Correlations between the phase information of adjacent phases and (static and dynamic) measures of nonlinearities are established and their origin is explained. By applying a set of simple constraints on the phases of an originally linear and uncor- related Gaussian time series, the observed scaling behavior of the intensity distribution of empirical time series can be reproduced. The power law character of the intensity distributions being typical for e.g. turbulence and financial data can thus be explained in terms of phase correlations.

description: Formulating consistent theories describing strongly correlated metallic topological phases is an outstanding problem in condensed matter physics. In this work we derive a theory defining a fractionalized analogue of the Weyl semimetal state: the fractional chiral metal. Our approach is to construct a 4+1D quantum Hall insulator by stacking 3+1D Weyl semimetals in a magnetic field. In a strong enough field the low-energy physics is determined by the lowest Landau level of each Weyl semimetal, which is highly degenerate and chiral, motivating us to use a coupled-wire approach. The one-dimensional dispersion of the lowest Landau level allows us to model the system as a set of degenerate 1+1D quantum wires that can be bosonized in the presence of electron-electron interactions and coupled such that a gapped phase is obtained, whose response to an electromagnetic field is given in terms of a Chern-Simons field theory. At the boundary of this phase we obtain the field theory of a 3+1D gapless fractional chiral state, which we show is consistent with a previous theory for the surface of a 4+1D Chern-Simons theory. The boundary's response to an external electromagnetic field is determined by a chiral anomaly with a fractionalized coefficient. We suggest that such anomalous response can be taken as a working definition of a fractionalized strongly correlated analogue of the Weyl semimetal state.

description: We present a new code designed to solve the equations of classical ideal magneto-hydrodynamics (MHD) in three dimensions, submitted to a constant gravitational field. The purpose of the code centers on the analysis of solar phenomena within the photosphere-corona region. We present 1D and 2D standard tests to demonstrate the quality of the numerical results obtained with our code. As solar tests we present the transverse oscillations of Alfvenic pulses in coronal loops using a 2.5D model, and as 3D tests we present the propagation of impulsively generated MHD-gravity waves and vortices in the solar atmosphere. The code is based on high-resolution shock-capturing methods, uses the HLLE flux formula combined with Minmod, MC and WENO5 reconstructors. The divergence free magnetic field constraint is controlled using the Flux Constrained Transport method.

Impact of surface collisions on enhancement and quenching of the luminescence near the metal nanoparticles

description: The fact that surface-induced damping rate of surface plasmon polaritons (SPPs) in metal nanoparticles increases with the decrease of particle size is well known. We show that this rate also increases with the degree of the mode confinement, hence damping of the higher order nonradiative SPP modes in spherical particles is greatly enhanced relative to damping of the fundamental (dipole) SPP mode. Since higher order modes are the ones responsible for quenching of luminescence in the vicinity of metal surfaces, the degree of quenching increases resulting in a substantial decrease in the amount of attainable enhancement of the luminescence
Promotion of geopolitical interests through military intervention in regional conflicts: US/NATO intervention in former Yugoslavia in 1999 and Russian incursion into Georgia in 2008

description: The August 2008 Russian use of force against sovereign Georgia shocked the international community. The intervention triggered comparisons with the US-led NATO military intervention into the former Yugoslavia in 1999. This paper explores key foreign policy interests of the US and Russia and examines how these interests were expressed in these military interventions. The analysis revealed similarities in goals and differences in approaches. Both the US and Russia promoted their national geopolitical interests through military intervention. Nevertheless, there are considerable differences in their peace-mediation approaches with the involvement of international institutions preceding military intervention. The author believes that Russia's incursion into Georgia sends a strong message to newly independent states, in particular Ukraine, about the possible consequences of seeking close relations with the West. Indeed, the building of mutual trust and understanding between the United States and Russia provides the best hope for overcoming future aggressive actions in response to other regional conflicts in the post-Soviet space.
Evaluating Flexure of the Mandible on Opening as Captured by Intraoral Scanners
Creators: name: Rich, Josiah
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2017

description: Aims: The mandible flexes on opening, constricting the width in the transverse dimension. Digital intraoral scanners require the patients’ mandible to approach maximum opening during capture. This study compares positional changes of teeth as captured by intraoral scans, alginate impressions, and Cone Beam Computed Tomography (CBCT). Methods: Thirty subjects had alginate impressions, intraoral scans and CBCT scans taken. Digital surface models (STL) were generated for each method, superimposed and total mean surface errors of the teeth were calculated. Results: The mean error was greatest at the molars. Error of open alginate to CBCT scan was 0.440mm±0.146, closed alginate to CBCT was 0.428mm±0.124, and intraoral scan to CBCT was 0.337mm±0.154 all at the molar region. Intraoral scans captured less mandibular flexure than alginate impressions and can be used for any purpose previously done with alginate.

description: The induced-activity investigations in off-line analysis performed in different experiments, concerning pre-actinide and actinide nuclei, are here presented and discussed. Generalized expressions for the determination of independent yields/cross sections of radioactive nuclei, formed in the targets, are derived and analysed. The fragment mass distribution from U-238, Th-232 and Ta-181 photofission at the bremsstrahlung end-point energies of 50 and 3500 MeV, and from Am-241, U-238 and Np-237 fission induced by 660-MeV protons, are scrutinized from the point of view of the multimodal fission approach. The results of these studies are hence compared with theoretical model calculations using the CRISP code. We subsequently discuss the complex particle-induced reaction, such as heavy-ions and deuterons, by using the thick-target thick-catcher technique and the two-step vector model framework as well. This is accomplished in order to present the investigation of the main processes (fission, spallation and (multi)fragmentation) in intermediate- and high-energy ranges of the incident particle. The set of experimental data, presented in this work, encompasses not merely the data as total production cross sections. Notwithstanding, it further covers other data, as individual yields/cross sections, charge, mass and spin distributions of the reaction fragments, as well as kinematic features. These sources of experimental data can serve as a consistent set of benchmarking data, still necessary for the study of heavy nuclei. Besides, it is also useful for technological applications, from astrophysics and environmental sciences to accelerator technology and accelerator-based nuclear waste transmutation and energy amplification as well.
