description: New Zealand’s 2020 cannabis legalisation referendum was narrowly defeated. Some post-referendum commentary claimed that the anti-reform campaign dominated the information space. Digital media represented a new forum for referendum advocacy. We analysed reporting on the cannabis referendum by six leading New Zealand digital news providers and Facebook advocacy campaigns ‘for’ and ‘against’ legalisation during 3 months pre-referendum. The mean sentiment score of media articles was marginally supportive of reform (+0.4 on a scale of −2 to +2). On average, pro-legalisation articles were re-published more often (2.3 vs 1.5 times for anti-reform), received better website placement (52% of articles published in the prime website section) and had more Facebook interactions (mean 1129 vs 771 for anti-reform). Ninety six per cent of articles were shared on Facebook, including via paid advertising. The principal pro-legalisation campaigner spent four times as much on Facebook advertising as the principal anti-legalisation campaigner. The networked map of Facebook posts illuminated links between digital media and cannabis advocacy. We find that pro-legalisation campaign dominated the digital information space, while the anti-legalisation campaign relied on traditional media, such as billboards. Combining media sentiment analysis with network analysis of social media posts provided new insights into the cannabis referenda debate.

description: We present a numerical method to simulate non-equilibrium Floquet steady states of one-dimensional periodically-driven (Floquet) many-body systems coupled to a dissipative bath, called open-system Floquet DMRG (OFDMRG). This method is based on a matrix product operator ansatz for the Floquet density matrix in frequency-space, and enables access to large systems beyond the reach of exact master-equation or quantum trajectory simulations, while retaining information about the periodic micro-motion in Floquet steady states. An excited-state extension of this technique also allows computation of the dynamical approach to the steady state on asymptotically long timescales. We benchmark the OFDMRG approach with a driven-dissipative Ising model, and apply it to study the possibility of dissipatively stabilizing pre-thermal discrete time-crystalline order by coupling to a cold bath.

description: The present study reports the formation of self-assembled droplet pattern on the PDMS polymer coated over grooved side of DVD under saturated vapours of alcohols. Comparison of the results with breath figures formed over unconstrained side of DVD is made. Four different environments namely methanol, ethanol, 2-propanol and n-butanol are used for the analysis. It is observed that the pattern formation occurs with methanol and ethanol vapours and not with 2-propanol and n-butanol. The difference is pattern formation with different alcohols is attributed to the variation in chain length and the presence of hydrophobic groups in alcohols, as given by Traube's rule. The distortion of patterns over constrained surface is attributed to the depinning of contact lines.

description: Experimental data on proton-proton interactions in high energy collisions show quite a special and unexpected behaviour of the proportion of elastic scattering compared to inelastic processes with increasing energy. It decreases at the beginning (at comparatively low energies) but then starts increasing. From Intersecting Storage Rings (ISR) energies of 23.5 - 62.5 GeV up to higher energies 7 - 13 TeV at the Large Hadron Collider (LHC) it increases by a factor more than 1.5! According to intuitive classical ideas we would expect a stable tendency with increasing proportion of the break-down of protons compared to their survival probability. One can assume that either the asymptotic freedom or the extremely short time of flight of high energy protons through each other are in charge of such a surprising effect. The unquestionable principle of unitarity combined with the available experimental data on elastic scattering is used to get new conclusions about the shape of the interaction region of colliding protons. Its evolution at present energies is considered. Some predictions about its behaviour at even higher energies are described with different assumptions on relative roles of elastic scattering and inelastic processes. The shape can transform rather drastically if the proportion of elastic processes keeps rising. This unexpected property leads to an unexpected corollary. The possible origin of the effect and its interrelation to the strong interaction dynamics are speculated.
Entangled multiplets and unusual spreading of quantum correlations in a continuously monitored tight-binding chain

description: We analyze the dynamics of entanglement in a paradigmatic noninteracting system subject to continuous monitoring of the local excitation densities. Recently, it was conjectured that the evolution of quantum correlations in such system is described by a semi-classical theory, based on entangled pairs of ballistically propagating quasiparticles and inspired by the hydrodynamic approach to unitary (integrable) quantum systems. Here, however, we show that this conjecture does not fully capture the complex behavior of quantum correlations emerging from the interplay between coherent dynamics and continuous monitoring. We unveil the existence of multipartite quantum correlations which are inconsistent with an entangled-pair structure and which, within a quasiparticle picture, would require the presence of larger multiplets. We also observe that quantum information is highly delocalized, as it is shared in a collective {\it nonredundant} way among adjacent regions of the many-body system. Our results shed new light onto the behavior of correlations in quantum stochastic dynamics and further show that these may be enhanced by a (weak) continuous monitoring process.

description: The propulsion type plasma in oblique external magnetic field is studied in 2D3V PIC MCC simulations. A periodical structure with maxima of electron and ion densities appears with an increase of an obliqueness of magnetic field. These ridges of electron and ion densities are aligned with the magnetic field vector and shifted relative each other. As a result the two-dimensional double-layers structure forms in cylindrical plasma chamber. The ion and electron currents on the side wall are essential modulated by the oblique magnetic field.

description: We consider the optimisation of the observing strategy (cadence, exposure time and filter choice) using medium size (2-m class) optical telescopes in the follow-up of kilonovae localised with arcminute accuracy to be able to distinguish among various kilonova models and viewing angles. To develop an efficient observation plan, we made use of the synthetic light curves obtained with the Monte Carlo radiative transfer code POSSIS for different kilonova models and as a function of different viewing angles and distances. By adding the appropriate photon counting noise to the synthetic light curves, we analysed four alternative sequences having the same total time exposure of 8 hours, with different time windows (0.5, 1, 2, 4 h), each with $i$, $r$, and $u$ filters, to determine the observing sequence that maximises the chance of a correct identification of the model parameters. We suggest to avoid $u$ filter and to avoid the use of colour curves. We also found that, if the error on distance is $\le$ 2%, 0.5, 1, 2-hour time window sequences are equivalent, so we suggest to use 2-hour one, because it has 1 day cadence, so it can be easily realised. When the distance of the source is unknown, 0.5 h time window sequence is preferable.

description: Distributed antenna arrays have been proposed for many applications ranging from space-based observatories to automated vehicles. Achieving good performance in distributed antenna systems requires stringent synchronization at the wavelength and information level to ensure that the transmitted signals arrive coherently at the target, or that scattered and received signals can be appropriately processed via distributed algorithms. In this paper we address the challenge of high precision time synchronization to align the operations of elements in a distributed antenna array and to overcome time-varying bias between platforms due to oscillator drift. We use a spectrally sparse two-tone waveform, which obtains approximately optimal time estimation accuracy, in a two-way time transfer process. We also describe a technique for determining the true time delay using the ambiguous two-tone matched filter output, and we compare the time synchronization precision of the two-tone waveform with the more common linear frequency modulation (LFM) waveform. We experimentally demonstrate wireless time synchronization using a single pulse 40$\,$MHz two-tone waveform over a 90$\,$cm 5.8$\,$GHz wireless link in a laboratory setting, obtaining a timing precision of 2.26$\,$ps.

description: The vast majority of research on cognitive enhancement has focused on pharmacological cognitive enhancement (PCE), with relatively little exploration of public attitudes towards non-pharmacological cognitive enhancing substances. Limited research has investigated how the lay public ethically evaluates nootropic supplements (i.e. legal and purportedly natural over-the-counter products), or how such attitudes may differ from attitudes towards other cognitive enhancers. This experimental between-subjects study used a contrastive vignette technique to explore Irish students’ attitudes towards caffeine tablets, nootropic supplements and PCE. One-hundred-and-thirteen Irish university students participated in the study (46 male, 64 female), ranging from 18 to 25 years of age (M = 21.9). Quantitative analyses examined differences in mean attitudes between cognitive enhancement conditions and genders. Results suggest that the three forms of cognitive enhancement provoked similar moderate responses in relation to safety and authenticity, however, students were more concerned about implicit coercion in relation to PCE and reported heightened fairness concerns in relation to nootropic supplements. Nootropic supplements may have distinct ethical implications which are not simply equivalent to those that accompany PCE or caffeine tablets, raising questions surrounding the effects of novel cognitive enhancing products; financial barriers to legal non-pharmacological cognitive enhancement; and the permissibility of cognitive enhancement advertising.

description: The coherent one-way (COW) quantum key distribution (QKD) is a highly practical quantum communication protocol that is currently deployed in off-the-shelves products. However, despite its simplicity and widespread use, the security of COW-QKD is still an open problem. This is largely due to its unique security feature based on inter-signal phase distribution, which makes it very difficult to analyze using standard security proof techniques. Here, to overcome this problem, we present a simple variant of COW-QKD and prove its security in the infinite-key limit. The proposed modifications only involve an additional vacuum tail signal following every encoded signal and a balanced beam-splitter for passive measurement basis choice. Remarkably, the resulting key rate of our protocol is comparable with both the existing upper-bound on COW-QKD key rate and the secure key rate of the coherent-state BB84 protocol. Our findings therefore suggest that the secured deployment of COW-QKD systems in high loss optical networks is indeed feasible with minimal adaptations applied to its hardware and software.

description: The development of fluid-structure interaction (FSI) software involves trade-offs between ease of use, generality, performance, and cost. Typically there are large learning curves when using low-level software to model the interaction of an elastic structure immersed in a uniform density fluid. Many existing codes are not publicly available, and the commercial software that exists usually requires expensive licenses and may not be as robust or allow the necessary flexibility that in house codes can provide. We present an open source immersed boundary software package, IB2d, with full implementations in both MATLAB and Python, that is capable of running a vast range of biomechanics models and is accessible to scientists who have experience in high-level programming environments. IB2d contains multiple options for constructing material properties of the fiber structure, as well as the advection-diffusion of a chemical gradient, muscle mechanics models, and artificial forcing to drive boundaries with a preferred motion.

description: Special education (SPED) in the United States is an integral aspect of the public education system as seven million students qualify and receive services under the special education umbrella. With such a vast number of students receiving services, it is vital to critically analyze how special education is serving students from varying backgrounds. Minority students have historically been disadvantaged in the education system, and investigating how special education is serving this population of students is necessary to ensure equal opportunity for each child within SPED. While previous studies have looked at one aspect of minority students’ experience in special education, a holistic approach has not been taken. In this literature review, a holistic analysis is conducted on minority students’ (1) differential placement within special education models, (2) extent of parental involvement, and (3) differential outcomes once within the special education program. These three factors collectively contribute to the overall experience minority students have in special education. Analysis suggests that minority students are not placed in high inclusion models at the same rate as non-minority students, and parents of minority students face heightened challenges with involvement which restricts the extent to which the parent can serve as an equal partner on the individual education program (IEP) team. The results of this study are beneficial to policy makers as it entails a more encompassing analysis of the state of special education for minority students and will guide future improvements to ensure that special education is serving every child equally and effectively.

description: Alcohol Use Disorder (AUD) is a psychiatric syndrome that is prevalent in a large percentage of society. AUD is particularly important to study in adolescents ages 10-19 years, because this is a time of critical physical and neural development. Adolescents who are exposed to certain risk factors, such as low sociodemographic factors and limited social network, are more prone to develop AUD than adults exposed to the same risks. In recovery high schools around the US, adolescents are allowed a place for recovery where they are removed from risky environments. In this literature review, I analyze peer reviewed papers on risk factors and therapies surrounding continuing care for adolescent AUD. The risk factors include sociodemographic factors, genetics, health literacy, social networking, and conflict. The continuing care therapies analyzed include family based interventions, motivational interviewing, cognitive behavioral therapy, and 12-step facilitation. I then discuss the application of these therapies and risk factors in the context of the University High School at the University of Texas, a sober high school where students are removed from risky environments. I argue that recovery high schools are beneficial for the continuing care of adolescents in recovery. I also argue that the formation of recovery high schools in partnership with college universities is beneficial for both parties. The goals of this effort are to provide adolescents in recovery with a structured mentorship system and access to extracurricular activities, ultimately benefitting in recovery.
Evaluating the implementation of primary care behavioral health systems in college health: development of a theory-based understanding of the organization of integrated care
Creators: name: Readdean, Kevin C.
Publisher: name: No Publisher Supplied

description: The prevalence and severity of mental health conditions among US college students has continued to increase over the past several decades. One strategy to address this challenge is the implementation of the interdisciplinary primary care behavioral health (PCBH) care model within student health centers. The overall aim of this dissertation was to investigate how the barriers and facilitators associated with integrated college health systems combine to impact PCBH implementation fidelity in college health centers. An explanatory, sequential-dependent mixed methods comparative case study project was conducted. This included completing an analytic comparative review of the existing integrated college health literature, administering a PCBH fidelity survey of behavioral health clinicians in college health settings, and conducting structured interviews with college health personnel. The barriers and facilitators identified in the literature assisted in interpreting the survey and interview data. Overall, the findings suggested fidelity was driven by the independent aspects (activities of the behavioral health clinicians) more than the interdisciplinary aspects (collaboration between behavioral and primary care staff) of the PCBH model. Barriers to adhering to the interdisciplinary teamwork aspects of the PCBH model were mitigated through the purposeful cross-disciplinary communication through electronic health record systems and the utilization of diagnostic specific integrated care pathways. The synthesis of quantitative and qualitative data through the lens of implementation theory advanced testable hypotheses involving the use of contextual organizational strengths (facilitators) to mitigate operational challenges (barriers) in an effort to improve PCBH implementation fidelity. This dissertation adds to the college health integration literature and provides a foundation for future PCBH implementation research.

description: The Murchison Widefield Array (MWA) has collected hundreds of hours of Epoch of Reionization (EoR) data and now faces the challenge of overcoming foreground and systematic contamination to reduce the data to a cosmological measurement. We introduce several novel analysis techniques such as cable reflection calibration, hyper-resolution gridding kernels, diffuse foreground model subtraction, and quality control methods. Each change to the analysis pipeline is tested against a two dimensional power spectrum figure of merit to demonstrate improvement. We incorporate the new techniques into a deep integration of 32 hours of MWA data. This data set is used to place a systematic-limited upper limit on the cosmological power spectrum of $Δ^2 \leq 2.7 \times 10^4$ mK$^2$ at $k=0.27$ h~Mpc$^{-1}$ and $z=7.1$, consistent with other published limits, and a modest improvement (factor of 1.4) over previous MWA results. From this deep analysis we have identified a list of improvements to be made to our EoR data analysis strategies. These improvements will be implemented in the future and detailed in upcoming publications.

description: Across the country, emergency departments (EDs) are facing increases in the number of patients they see, overcrowding, lengths of stay, and worsening outcomes. In 2016, the CDC reported that there were 45.8 visits to EDs per 100 people, with less than half of patients being seen in under 15 minutes. ED patient volumes rise each year while no significant progress has been made in improving the operational process. This study aims to better understand the root of the problem that afflicts emergency departments by first evaluating the efficacy of current process-improvement interventions, and to then suggest possible ways to combine these strategies in order to yield even greater results. To do this, I conducted a systematic literature review to compile studies that are specific to the five process-improvement strategies so that they may each be thoroughly analyzed. Initial findings indicate that the Fast-Track Units and Physician-in-Triage strategies have had the most consistent success in improving patient wait times and emergency department overcrowding. However, the other strategies have significant benefits in other facets of the emergency process that require further consideration. Additionally, some of the strategies are able to be combined and require future research to discern their additive effects. Understanding the factors that ultimately create slow downs and bottlenecks in emergency departments opens up new ways to better patient care and without interventions to address these issues, both the patients and the hospital will face even worse outcomes.

description: We use a continuum model to examine the effect of activity on a phase separating mixture of an extensile active nematic and a passive fluid. We highlight the distinct role of previously considered interfacial active stresses and bulk active stresses that couple to liquid crystalline degrees of freedom. Interfacial active stresses can arrest phase separation, as previously demonstrated. Bulk extensile active stresses can additionally strongly suppress phase separation by sustained self-stirring of the fluid, substantially reducing the size of the coexistence region in the temperature/concentration plane relative to that of the passive system. The phase separated state is a dynamical emulsion-like steady state of continuously splitting and merging droplets, as suggested by recent experiments. Using scaling analysis and simulations, we identify various regimes for the dependence of droplet size on activity. These results can provide a criterion for identifying the mechanisms responsible for arresting phase separation in experiments.

description: Equivalent approaches to determine eigenfrequencies of the Liouvillians of open quantum systems are discussed using the solution of the Heisenberg-Langevin equations and the corresponding equations for operator moments. A simple damped two-level atom is analyzed to demonstrate the equivalence of both approaches. The suggested method is used to reveal the structure as well as eigenfrequencies of the dynamics matrices of the corresponding equations of motion and their degeneracies for interacting bosonic modes described by general quadratic Hamiltonians. Quantum Liouvillian exceptional and diabolical points and their degeneracies are explicitly discussed for the case of two modes. Quantum hybrid diabolical exceptional points (inherited, genuine, and induced) and hidden exceptional points, which are not recognized directly in amplitude spectra, are observed. The presented approach via the Heisenberg-Langevin equations paves the general way to a detailed analysis of quantum exceptional and diabolical points in infinitely dimensional open quantum systems.

description: We present the results of a National Science Foundation (NSF) Project Scoping Workshop, the purpose of which was to assess the current status of calculations for the nuclear matrix elements governing neutrinoless double-beta decay and determine if more work on them is required. After reviewing important recent progress in the application of effective field theory, lattice quantum chromodynamics, and ab initio nuclear-structure theory to double-beta decay, we discuss the state of the art in nuclear-physics uncertainty quantification and then construct a road map for work in all these areas to fully complement the increasingly sensitive experiments in operation and under development. The road map contains specific projects in theoretical and computational physics as well as an uncertainty-quantification plan that employs Bayesian Model Mixing and an analysis of correlations between double-beta-decay rates and other observables. The goal of this program is a set of accurate and precise matrix elements, in all nuclei of interest to experimentalists, delivered together with carefully assessed uncertainties. Such calculations will allow crisp conclusions from the observation or non-observation of neutrinoless double-beta decay, no matter what new physics is at play.
description: This Project Scoping Workshop report is focused on the US context for the theory of neutrinloess double beta decay. Its authors plan to produce a journal article that addresses similar issues, but is more inclusive as regards non-US efforts on this problem. We would be happy to receive further input that will help us refine our text before it is submitted to the journal

In doing so, we make use of the formalism of kinematic space [arXiv:1505.05515] and fields on this space, introduced in [arXiv:1604.03110]. We show that the gravitational dynamics are equivalent to a gauge invariant wave-equation on kinematic space and that this equation arises in natural correspondence to the conformal Casimir equation in the CFT.

description: The TBT project is being developed under ESA's General Studies and Technology Programme (GSTP), and shall implement a test-bed for the validation of an autonomous optical observing system in a realistic scenario within the Space Situational Awareness (SSA) programme of the European Space Agency (ESA). The goal of the project is to provide two fully robotic telescopes, which will serve as prototypes for development of a future network. The system consists of two telescopes, one in Spain and the second one in the Southern Hemisphere. The telescope is a fast astrograph with a large Field of View of 2.5 x 2.5 square-degrees and a plate scale of 2.2 arcsec/pixel. The tube is mounted on a fast direct-drive mount moving with speed up to 20 degrees per second. The focal plane hosts a 2-port 4K x 4K back-illuminated CCD with readout speeds up to 1MHz per port. Detection software and hardware are optimised for the detection of NEOs and objects in high Earth orbits (objects moving from 0.1-40 arcsec/second). Every night it takes all the input needed and prepares a schedule following predefined rules allocating tasks for the telescopes. Telescopes are managed by RTS2 control software, that performs the real-time scheduling of the observation and manages all the devices at the observatory.1 At the end of the night the observing systems report astrometric positions and photometry of the objects detected. The first telescope was installed in Cebreros Satellite Tracking Station in mid-2015. We evaluate the site characteristics and the performance of the TBT Cebreros telescope in the different modes and strategies. Average residuals for asteroids are under 0.5 arcsecond, while they are around 1 arcsecond for upper-MEO and GEO satellites. The survey depth is dimmer than magnitude 18.5 for 30-second exposures with the usual seeing around 4 arcseconds.

description: Stars are not perfectly spherically symmetric. They are deformed by rotation and magnetic fields. Until now, the study of stellar shapes has only been possible with optical interferometry for a few of the fastest-rotating nearby stars. We report an asteroseismic measurement, with much better precision than interferometry, of the asphericity of an A-type star with a rotation period of 100 days. Using the fact that different modes of oscillation probe different stellar latitudes, we infer a tiny but significant flattening of the star's shape of $ΔR/R = (1.8 \pm 0.6) \times 10^{-6}$. For a stellar radius $R$ that is $2.24$ times the solar radius, the difference in radius between the equator and the poles is $ΔR = 3 \pm 1$ km. Because the observed $ΔR/R$ is only one-third of the expected rotational oblateness, we conjecture the presence of a weak magnetic field on a star that does not have an extended convective envelope. This calls to question the origin of the magnetic field.

description: The quasi-one-dimensional rhombic array of the waveguides is considered. In the nonlinear case the system of equations describing coupled waves in the waveguides has the solutions that represent the superposition of the flat band modes. The property of stability of these solutions is considered. It was found that the flat band solution is unstable until the power threshold be attained.

description: Cryogenic solid state detectors are widely used in dark matter and neutrino experiments, and require a sensible raw data analysis. For this purpose, we present Cait, an open source Python package with all essential methods for the analysis of detector modules fully integrable with the Python ecosystem for scientific computing and machine learning. It comes with methods for triggering of events from continuously sampled streams, identification of particle recoils and artifacts in a low signal-to-noise ratio environment, the reconstruction of deposited energies, and the simulation of a variety of typical event types. Furthermore, by connecting Cait with existing machine learning frameworks we introduce novel methods, for better automation in data cleaning and background rejection.

description: Radiotherapy for vulvar carcinoma is challenging due to relatively high risk of locoregional disease recurrence, a technically challenging target, and postoperative lymphocele, and a high risk radiation sequelae. We aim to explore, if it is possible to reduce dose to normal tissue, while maintaining CTV coverage for this patient group with online adaptive radiotherapy. 20 patients with vulvar carcinoma (527 fractions) were treated with online adaptation on a Varian Ethos accelerator. Setup CBCTs were acquired daily for adaptive planning. Verification CBCTs were acquired immediately prior to dose delivery. CTV dose coverage and dose to bladder and rectum were extracted from the scheduled and adapted plans as well as from adapted plans recalculated based on verification CBCTs. In addition, analysis of the decision of the adaptive procedure was performed for 17 patients (465 fractions). Mean CTV D95% and standard deviation was 98% ± 5% for the scheduled plan compared to 100.0 ± 0.3% and 100.0 ± 0.8% for the adapted plan on the setup and verification CBCT respectively. Dose to OARs varied substantially and did not show any benefit from adaption itself, however a margin reduction was implemented after the first patients treated. The adapted plan was chosen for 63.5% of the fractions and dominant reasons for not adapting were ‘no significant dosimetric gain’ (75 fractions, 14%) and ‘Medical doctor (MD) not available for treatment’ (50 fractions, 9.5%). The median adaption time was 15 min and the 25th and 75th percentile was 12 and 17 min, respectively. CTVs and PTVs dose coverage were significantly improved with adaptation compared to image-guided RT. This gain was robust during the treatment time.

description: This monograph provides an overview of the mathematical theories and computational algorithm design for contagion source detection in large networks. By leveraging network centrality as a tool for statistical inference, we can accurately identify the source of contagions, trace their spread, and predict future trajectories. This approach provides fundamental insights into surveillance capability and asymptotic behavior of contagion spreading in networks. Mathematical theory and computational algorithms are vital to understanding contagion dynamics, improving surveillance capabilities, and developing effective strategies to prevent the spread of infectious diseases and misinformation.

description: In this work, we study the doping effects on the magnetic states of CuCrO2 based on the classical frustrated spin model [Lin et al., Phys. Rev. B 89, 220405(R) (2014)]. Several experimental observations can be well reproduced by the Monte Carlo simulations of the modified spin models. Our work suggests that the disorder induced by V/Al doping cooperated with the frustration in the system may contribute to the emergence of the spin glass state. Furthermore, the hole-doping by Mg2+ substituting Cr3+ enhances the quantum fluctuations and bond disorder which modulate the biquadratic exchanges, and in turn results in the promotion of the spiral phase, consistent with the experimental report.

description: We investigate the null controllability property of systems that mathematically describe the dynamics of some non-Newtonian incompressible viscous flows. The principal model we study was proposed by O. A. Ladyzhenskaya, although the techniques we develop here apply to other fluids having a shear-dependent viscosity. Taking advantage of the Pontryagin Minimum Principle, we utilize a bootstrapping argument to prove that sufficiently smooth controls to the forced linearized Stokes problem exist, as long as the initial data in turn has enough regularity. From there, we extend the result to the nonlinear problem. As a byproduct, we devise a quasi-Newton algorithm to compute the states and a control, which we prove to converge in an appropriate sense. We finish the work with some numerical experiments.
