Relation between tunneling and particle production in vacuum decay
Creators: name: Mersini, L.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 1999

description: The field-theoretical description of quantum fluctuations on the background of a tunneling field (Formula presented) is examined in the case of a functional Schrödinger approach. We apply this method in the case when quantum fluctuations are coupled to the (Formula presented) field through a mass-squared term, which is “time dependent” since we include the dynamics of (Formula presented) The resulting mode functions of the fluctuation field, which determine the quantum state after tunneling, display a previously unseen resonance effect when their mode number is comparable to the curvature scale of the bubble. A detailed analysis of the relation between the excitations of the field about the true vacuum (interpreted as particle creation) and the phase shift coming from tunneling is presented.

description: The history of modern condensed matter physics may be regarded as the competition and reconciliation between Stoner's and Anderson's physical pictures, where the former is based on momentum-space descriptions focusing on long wave-length fluctuations while the latter is based on real-space physics emphasizing emergent localized excitations. In particular, these two view points compete with each other in various nonperturbative phenomena, which range from the problem of high T$_{c}$ superconductivity, quantum spin liquids in organic materials and frustrated spin systems, heavy-fermion quantum criticality, metal-insulator transitions in correlated electron systems such as doped silicons and two-dimensional electron systems, the fractional quantum Hall effect, to the recently discussed Fe-based superconductors. An approach to reconcile these competing frameworks is to introduce topologically nontrivial excitations into the Stoner's description, which appear to be localized in either space or time and sometimes both, where scattering between itinerant electrons and topological excitations such as skyrmions, vortices, various forms of instantons, emergent magnetic monopoles, and etc. may catch nonperturbative local physics beyond the Stoner's paradigm. In this review article we discuss nonperturbative effects of topological excitations on dynamics of correlated electrons. ......

description: We numerically investigate the ground state, the Raman-driving dynamics and the nonlinear excitations of a realized spin-orbit-coupled Bose-Einstein condensate in a one-dimensional harmonic trap. Depending on the Raman coupling and the interatomic interactions, three ground-state phases are identified: stripe, plane wave and zero-momentum phases. A narrow parameter regime with coexistence of stripe and zero-momentum or plane wave phases in real space is found. Several sweep progresses across different phases by driving the Raman coupling linearly in time is simulated and the non-equilibrium dynamics of the system in these sweeps are studied. We find kinds of nonlinear excitations, with the particular dark solitons excited in the sweep from the stripe phase to the plane wave or zero-momentum phase within the trap. Moreover, the number and the stability of the dark solitons can be controlled in the driving, which provide a direct and easy way to generate dark solitons and study their dynamics and interaction properties.

Use-wear analysis

description: This method aims to plot the distribution and location of use-wear data, using basic GIS methods. This short tutorial explains how to create and edit the GIS templates for lithic use-wear analysis, using free and open-access software for image editing and GIS analysis. The aim of this tutorial is to introduce the template, facilitate its use and editing, and at the same time encourage colleagues to feed this work with new templates, including new tool types.
 The method and GIS templates are based and deeply inspired by the work of Orton, D. C. (2010). A new tool for zooarchaeological analysis: ArcGIS skeletal templates for some common mammalian species. Internet Archaeology, (28). (https://intarch.ac.uk/journal/issue28/4/toc.html). Similar concept, method and workflow are here applied on mapping use-wear on lithic tools.

description: According to the recent results of the neutrino oscillation experiment MINOS, the neutrino mixing angle $θ_{23}$ may not be maximal ($45^{\circ}$). Two nearly degenerate solutions are possible, one in the lower octant (LO) where $θ_{23}<45^{\circ}$, and one in the higher octant (HO) where $θ_{23}>45^{\circ}$. Long baseline experiments measuring the $ν_μ\rightarrowν_{e}$ are capable of resolving this degeneracy. In this work we study the potential of the planned European LBNO experiment to distinguish between the LO and HO solutions.

A New Direction for Ethiopia’s Healthcare System: Building Health System Capacity to Facilitate National Health Insurance Integration
Creators: name: Kaleab Worku
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2023

description: Ethiopia can advance towards developing a national health insurance to mitigate the high disease burden in the country and the catastrophic financial burden of seeking healthcare on households. Instituting a national health insurance model requires an efficient health system that has the capacity to support its successful implementation. By upscaling the current health system to meet minimum standards for essential health system components that have been proposed by the WHO or other organizations, Ethiopia can prepare itself for the establishment of a national health insurance. The rapid economic growth of Ethiopia can support increasing fiscal space in the health sector to strengthen it. Costing scenarios can be explored to estimate the costs of reaching targets to strengthen the health system. Currently, several community-based health insurance (CBHI) schemes have been piloted across several regions in the country. CBHIs may not be the solution for Ethiopia due to their unsustainability, but the results of the schemes’ current impact can provide public health leaders with a guidance in understanding factors such as member enrollment, program spending, quality of care, and member retainment. These lessons can support the planning of a national-scale health insurance program.

description: In this paper we present an evolutionary optimization approach to solve the risk parity portfolio selection problem. While there exist convex optimization approaches to solve this problem when long-only portfolios are considered, the optimization problem becomes non-trivial in the long-short case. To solve this problem, we propose a genetic algorithm as well as a local search heuristic. This algorithmic framework is able to compute solutions successfully. Numerical results using real-world data substantiate the practicability of the approach presented in this paper.

description: We provide a detailed quantitative description of singular inflation. Its close analogy with finite-time future singularity which is associated to dark energy era is described. Calling and classifying the singularities of such inflation as finite-time cosmological singularities we investigate their occurrence, with special emphasis on the Type IV singularity. The study is performed in the context of a general non-canonical scalar-tensor theory. In addition, the impact of finite time singularities on the slow-roll parameters is also investigated. Particularly, we study three cases, in which the singularity occurs during the inflationary era, at the end, and also we study the case that the singularity occurs much more later than inflation ends. Using the obtained slow-roll parameters, for each case, we calculate explicitly the spectral index of primordial curvature perturbations $n_s$, the associated running of the spectral index $a_s$ and of the scalar-to-tensor ratio $r$ and compare the resulting values to the Planck and BICEP2 data. As we demonstrate, in some cases corresponding to the Type IV singularity, there might be the possibility of agreement with the observational data, when the singularity occurs at the end, or after inflation. However, absolute concordance of all observational indices is not achieved. On the contrary, if the singularity occurs during the inflationary era, this is catastrophic for the theory, since the observational indices become divergent. We also show how a Type IV singularity may be consistently accommodated in the Universe's late time evolution.

Compared to classical limiter functions in the MUSCL framework, which yield $2^{\text{nd}}$-order accuracy, the new limiter is $3^\text{rd}$-order accurate for smooth solutions. In an earlier work, such a $3^\text{rd}$-order limiter function was proposed and showed successful results [2]. However, it came with unspecified parameters. We close this gap by giving information on these parameters.

description: Carbon nanotubes (CNTs) are an effective spacer to prevent the re-stacking of graphene layers. However, the aggregation of CNTs always reduces the specific surface area of resulting CNT/graphene composites. Meanwhile, different pores always have different contributions to the specific capacitance. In this study, CNT/graphene composites with different porous structures are synthesized by co-reduction of oxidized CNTs and graphene oxide with different mixing ratios. With an optimized CNT content of 20%, the CNT/graphene composite shows 206 F g−1 in 1-ethyl-3-methylimidazolium tetrafluoroborate electrolyte. It is found that pores larger than twice the size of electrolyte ions can make greater contributions to the specific capacitance.

description: We consider the space-like D$p$ brane solutions of type II string theories having isometries ISO$(p+1)$ $\times$ SO$(8-p,1)$. These are asymptotically flat solutions or in other words, the metrics become flat at the time scale $τ\gg τ_0$. On the other hand, when $τ\sim τ_0$, we get $(p+1)+1$ dimensional flat FLRWmetrics upon compactification on a $(8-p)$ dimensional hyperbolic space with time dependent radii. We show that the resultant $(p+1)+1$ dimensional metrics describe transient accelerating cosmologies for all $p$ from 1 to 6, i.e., from $(2+1)$ to $(7+1)$ space-time dimensions. We show how the acceleration changes with the interplay of the various parameters characterizing the solutions in $(3+1)$ dimensions. Finally, for $τ\ll τ_0$, after compactification on $(8-p)$ dimensional hyperbolic space, the resultant metrics are shown to take the form of $(p+1)+1$ dimensional de Sitter spaces upto a conformal transformation. Cosmologies here are decelerating, but, only in a particular conformal frame we get eternal acceleration.

description: For Doppler-broadened media operating under double-double electromagnetically induced transparency (EIT) conditions, we devise a scheme to control and reduce the probe-field group velocity at the center of the second transparency window. We derive numerical and approximate analytical solutions for the width of EIT windows and for the group velocities of the probe field at the two distinct transparency windows, and we show that the group velocities of the probe field can be lowered by judiciously choosing the physical parameters of the system. Our modeling enables us to identify three signal-field strength regimes (with a signal-field strength always higher than the probe-field strength), quantified by the Rabi frequency, for slowing the probe field. These three regimes correspond to a weak signal field, with the probe-field group velocity and transparency window width both smaller for the second window compared to the first window, a medium-strength signal field, with a probe-field group velocity smaller in the second window than in the first window but with larger transparency-window width for the second window, and the strong signal field, with both group velocity and transparency window width larger for the second window. Our scheme exploits the fact that the second transparency window is sensitive to a temperature-controlled signal-field nonlinearity, whereas the first transparency window is insensitive to this nonlinearity.

description: Direct observations of gaseous exoplanets reveals that their gas envelope is commonly enriched in C/O ratio compared to that of the host star. This has been explained by considering that the gas phase of the disc could be inhomogeneous, exceeding the stellar C/O ratio in regions where these planets formed; but few studies have considered the drift of the gas and the migration of planets. We aim to derive the gas composition in planets to evaluate if the formation of giant planets with an enriched C/O ratio is possible. The study focusses on the effects of different processes on the C/O ratio like the disc evolution, the drift of gas, and the migration of the planet. We used our previous models for computation of the chemical composition together with the planet formation model of Alibert et al. (2013), to which we added the composition and drift of the gas phase of the disc composed of major volatile species, H2 and He. The study focusses on the region where ice lines are present and influence the C/O ratio of the planets. Modelling shows that the condensation of volatile species allows for C/O enrichment in specific parts of the protoplanetary disc, of up to 4 times the solar value. This leads to the formation of planets that can be enriched in C/O in their envelope up to 3 times the solar value. The migration of planets, the evolution of the gas phase, and the irradiation of the disc enables the evolution of the initial C/O ratio with a decrease in the outer part of the disc and an increase in the inner part. The total C/O ratio of the planets is governed by the contribution of ices accreted, suggesting that high C/O ratios measured in planetary atmospheres are indicative of a lack of exchange of material between the core of a planet and its envelope or an observational bias, and suggesting that the observed C/O ratio is not representative of the total C/O ratio of the planet.

Global modes in nonlinear non-normal evolutionary models: exact solutions, perturbation theory, direct numerical simulation, and chaos

description: This paper is concerned with the theory of generic non-normal nonlinear evolutionary equations, with potential applications in Fluid Dynamics and Optics. Two theoretical models are presented. The first is a model two-level non-normal nonlinear system that not only highlights the phenomena of linear transient growth, subcritical transition and global modes, but is also of potential interest in its own right in the field of nonlinear optics. The second is the fairly familiar inhomogeneous nonlinear complex Ginzburg--Landau (CGL) equation. The two-level model is exactly solvable for the nonlinear global mode and its stability, while for the spatially-extended CGL equation, perturbative solutions for the global mode and its stability are presented, valid for inhomogeneities with arbitrary scales of spatial variation and global modes of small amplitude, corresponding to a scenario near criticality. For other scenarios, a numerical iterative nonlinear eigenvalue technique is preferred. Two global modes of different amplitudes are revealed in the numerical approach. For both the two-level system and the nonlinear CGL equation, the analytical calculations are supplemented with direct numerical simulation, thus showing the fate of unstable global modes. For the two-level model this results in unbounded growth of the full nonlinear equations. For the spatially-extended CGL model in the subcritical regime, the global mode of larger amplitude exhibits a `one-sided' instability leading to a chaotic dynamics, while the global mode of smaller amplitude is always unstable (theory confirms this). However, advection can stabilize the mode of larger amplitude.

description: Transition metal carbonates (TMCs) with complex composition and robust hybrid structure hold great potential as high-performance electrode materials for lithium-ion batteries (LIBs). However, poor ionic/electronic conductivities and large volume changes of TMCs during lithiation/delithiation processes have hindered their applications. Herein, single-phase MnCo mixed carbonate composites encapsulated by reduced graphene oxide (MnxCo1− xCO3/RGO), in which Mn and Co species are distributed randomly in one crystal structure, are successfully synthesized through a facial liquid-state method. When evaluated as LIB anodes, the MnxCo1− xCO3/RGO composites exhibit enhanced electrochemical performance compared with the reference CoCO3/RGO and MnCO3/RGO. Specifically, the Mn0.7Co0.3CO3/RGO delivers an ultrahigh capacity of 1454 mA h g−1 after 130 cycles at 100 mA g−1 and exhibits an ultralong cycling stability (901 mA h g−1 after 1500 cycles at 2000 mA g−1). This is the best lithium storage performance among carbonate-based anodes reported up to date. Such superb performance is attributed to the hybrid structure and enhanced electroconductivity due to the integration of Co and Mn into one crystal structure, which is complemented by electrochemical impedance spectroscopy and density functional theory calculations. The facile synthesis, promising electrochemical results, and scientific understanding of the MnxCo1− xCO3/RGO provides a design principle and encourages more research on TMCs-based electrodes.

description: Hexagonal BCN (h-BCN) has been identified as a promising class of electromagnetic wave (EMW) absorption material for critical Mach number aerocraft due to its exceptional thermal and chemical stabilities as well as adjustable dielectric property. Herein, we report a facile precursor synthesis-pyrolysis method to obtain ultra-light h-BCN bulk ceramics and microtubes (MTs) using commercially available BCl3, ethylenediamine and aniline as the monomers. The h-BCN bulk with a density of 15 mg/cm3 can be in situ synthesized derived from the precursor located in a tube furnace, while h-BCN MTs are simultaneously obtained on the downstream graphite sheets by controlling the pyrolysis temperature at the wide range of 800–1200 °C. For the h-BCN bulk ceramics, the minimum reflection loss (RL) can be tailored by controlling the N dopants, ranging from −52.7 dB at 5.44 GHz (the band width below −10 dB is achieved in a wide frequency range from 2.8 to 18 GHz) to −20.6 dB at 14.8 GHz (the band width below −10 dB is narrowed from 13.4 to 18 GHz). The excellent and frequency-controllable microwave absorption properties are due to the combination of tunable complex permittivity and lattice polarization resulting from B and N dopants in carbon networks.

description: We generalize S-duality to N=2 superconformal field theories (SCFTs) with Coulomb branch operators of non-integer scaling dimension. As simple examples, we find minimal generalizations of the S-dualities discovered in SU(2) gauge theory with four fundamental flavors by Seiberg and Witten and in SU(3) gauge theory with six fundamental flavors by Argyres and Seiberg. Our constructions start by weakly gauging diagonal SU(2) and SU(3) flavor symmetry subgroups of two copies of a particular rank-one Argyres-Douglas theory (along with sufficient numbers of hypermultiplets to guarantee conformality of the gauging). As we explore the resulting conformal manifold of the SU(2) SCFT, we find an action of S-duality on the parameters of the theory that is reminiscent of Spin(8) triality. On the other hand, as we explore the conformal manifold of the SU(3) theory, we find that an exotic rank-two SCFT emerges in a dual SU(2) description.

description: Single- and double-walled WS2 nanotubes of small diameter (<10 nm) and few layers (<4) have been synthesized by heating ultrathin W18O49 nanowires and S powders in an H2/Ar atmosphere at 840°C. In the process of formation and growth of a WS2 nanotube, the W18O49 phase transformed first into an amorphous WS3 structure via the absorption and diffusion of the sulfur atoms to substitute the oxygen atoms, and followed by a phase transition from amorphous WS3 to 2H-WS2 by losing sulfur atoms to form the shell of the WS2 nanotube.
AtlantECO - Atlantic Ecosystems Assessment, Forecasting & Sustainability
Creators: name: AtlantECO Consortium
Publisher: name: Zenodo
Year: 2020

description: The ambition of AtlantECO is to develop and apply a novel, unifying framework that provides knowledge-based resources to design policies, support decisions making and engage with citizens to encourage responsible behaviour to manage the Atlantic system and protect its Ecosystem Services (ES) provision. The aim of AtlantECO is to determine the structure and function of Atlantic microbiome in the context of ocean circulation and presence of pollutants, e.g., plastics, to assess its role in driving the dynamics of Atlantic ecosystems at basin and regional scales; its potential of being used as a sensor of ecosystem state and the mechanisms by which it drives the provision of five ES. This is key to improve our predictions on future provision of ES in the basin and to favour the establishment of a sustainable Blue Growth strategy for an All-Atlantic community. To realise this vision, AtlantECO has four objectives which are to 1) Assess dynamics of Atlantic marine ecosystems, their ES provision and the interplay of both with socio-economic activities; 2 increase knowledge and data on microbiomes, plastics, the plastisphere and carbon fluxes that support ecosystems at basin scale using best practices and integrative sampling strategies, novel genomics, imaging and biogeochemical methods, bioinformatics and modelling approaches; 3) Assess and predict the cumulative impacts of multiple stressors on ecosystem status and dynamics and ES provision, identifying their drivers and role on tipping points, assessing their changes in recovery of ecosystem structures, functions and services, and developing eco-socio-economic models to predict future trajectories and 4) Deploy a systemic strategy to build capacity and transfer knowledge for a seamless engagement between science, industry, policy, and society. To achieve these objectives AtlantECO brings together experts and pioneers from Europe, South America and South Africa with the relevant resources, knowledge and experience.

description: We investigate the fragmented many-body ground states of a spin-2 Bose gas in zero magnetic field.\ We point out that the exact ground state is not simply an average over rotationally-invariant mean-field states, in contrast to the spin-1 case with even number of particles N.\ We construct the exact ground states and compare them with the angular-averaged polar and cyclic states.\ The angular-averaged polar states fail to retrieve the exact eigenstate at $N$ $\ge$ $6$ while angular-averaged cyclic states sustain only for N with a multiple of $3$.\ We calculate the density matrices and two-particle density matrices to show how deviant the angular-averaged state is from the exact one.

description: This research paper delves into the pivotal role of Explainable AI (XAI) in fostering ethical decision-making within healthcare systems. As artificial intelligence (AI) increasingly influences critical healthcare decisions, the need for transparent and interpretable AI models becomes essential to ensure trust, fairness, and accountability.The paper begins with an overview of the integration of AI in healthcare, emphasizing the growing importance of ethical considerations. It highlights the challenges inherent in AI-based systems, including issues of transparency, accountability, and the ethical implications of decision-making in critical health scenarios.A comprehensive literature review covers existing XAI methods such as Local Interpretable Model-Agnostic Explanations (LIME) and SHapley Additive exPlanations (SHAP), and explores their applications and effectiveness in healthcare. The discussion extends to ethical decision-making theories and how they can be applied to AI systems to align with moral and ethical standards.The research proposes a robust framework for implementing XAI in healthcare settings, detailing tailored approaches to XAI methods, steps to ensure ethical and transparent decision-making, and the integration of human oversight in AI-driven healthcare decisions. This framework aims to bridge the gap between advanced AI technologies and the ethical requirements of healthcare practice.The paper concludes by examining the implications of XAI on ethical practices in healthcare, comparing these practices with existing AI models, and identifying future research opportunities. The impact of XAI on enhancing transparency and trust between healthcare professionals and AI systems is evaluated, along with suggestions for optimizing XAI methods and integrating emerging technologies.This research contributes to the ongoing discourse on ethical AI by providing actionable insights and a structured approach to implementing XAI in healthcare, ultimately aiming to advance patient-centered care and ensure that AI technologies are used responsibly and ethically.

description: Employing $ab$ $intito$ electronic structure calculations, we have investigated electronic and magnetic properties of the Zr-based quanternary Heusler alloys: ZrCoVIn, ZrFeVGe, ZrCoFeP, ZrCoCrBe and ZrFeCrZ (Z=In and Ga). Our $ab$ $intito$ calculation results show that all the alloys are (or nearly) spin-gapless semiconductors. All the alloys have large band gaps, indicating the stability of them at room temperature. The Slater-Pauling behaviours of these alloys are discussed as well. The values of Curie temperature of all the alloys are estimated. And it is found that the values of the Curie temperature for all our calculated quanternary Heusler alloys are higher than that of room temperature.

description: Unequal electrode capacitance in a symmetric supercapacitor results in an unequal voltage distribution on the two electrodes and the supercapacitor usually cannot utilize the full electrochemical window of electrolyte. In this study, the voltage distribution on the two electrodes of graphene supercapacitor is optimized by an adjustment of electrode mass ratio from 1 to 1.5 and an enlarged energy density of 118 Wh kg−1 is achieved at operating voltage 4.7 V using an ionic liquid electrolyte 1-methyl-1-propylpiperidinium bis (trifluoromethyl sulfonyl) imide (MPPp-TFSI).

description: We report on the feedback-optimized extraordinary optical transmission of continuous-variable entangled states through a hexagonal metal-hole array. The continuous-variable entanglements from a nondegenerate optical parametric amplifier are first demonstrated to survive after a photon-plasmon-photon conversion process. By controlling the reflected light from the metal-hole array, a significant enhancement of quantum correlations has then been experimentally achieved comparing to the case of without such coherent feedback control. This result presents a useful technique to efficiently recover the substantial reflective losses in the plasmonic circuits for quantum information processing.

description: We describe the structural parameters and atomic positions of a single-walled WS2 nanotube. The structure factor is calculated in detail using analytic expressions for both single-walled and multi-walled WS2 nanotubes. A zoning scheme has been developed to obtain the ratio m/n from the electron diffraction patterns. The procedure for determination of the chiral indices of both single-walled and multi-walled WS2 nanotubes and the tilt angle is illustrated in detail for either normal incidence or inclined incidence. As an example of application, the determination of the chiral indices of a five-shell WS2 nanotube was carried out and the tilt angle was obtained as 17.7°. The method developed here is useful and valid to determine the atomic structure of WS2 nanotubes.

description: Mn-Based compounds with high reversible capacities and eco-friendliness are one of the most promising anode materials for lithium ion batteries (LIBs), but their practical applications are still hindered by low rate capability, poor cycling stability, and high cost of production. Herein, we synthesize MnCO3/Mn3O4/reduced graphene oxide (MnCO3/Mn3O4/RGO) ternary composites through a green and facile strategy, which can take full advantage of the raw materials, mitigate pollution effectively, simplify the operating procedure, and shorten the preparation time to realize large-scale preparation. When used as anode materials for LIBs, benefitting from the advantage of their structure and effective synergy among MnCO3, Mn3O4 and graphene, the ternary composites exhibit an excellent cycling stability of 988 mA h g-1 after 200 cycles at 100 mA g-1 and 532 mA h g-1 after 800 cycles at 1 A g-1, which is superior to those of binary MnCO3/RGO and Mn3O4/RGO composites. Analyses using cyclic voltammetry, charge/discharge profiles, and electrochemical impedance spectroscopy reveal improved kinetics in the electrochemical reaction of the MnCO3/Mn3O4/RGO ternary composite with cycling. Furthermore, a systematic study of the potential difference of the redox reaction provides a good explanation for the observed electrochemical performance of the ternary composites.

description: We calculate the two-photon exchange corrections to electron-proton scattering with nucleon and $Δ$ intermediate states. The results show a dependence on the elastic nucleon and nucleon-$Δ$-transition form factors used as input which leads to significant changes compared to previous calculations. We discuss the relevance of these corrections and apply them to the most recent and precise data set and world data from electron-proton scattering. Using this, we show how the form factor extraction from these data is influenced by the subsequent inclusion of physical constraints. The determination of the proton charge radius from scattering data is shown to be dominated by the enforcement of a realistic spectral function. Additionally, the third Zemach moment from the resulting form factors is calculated. The obtained radius and Zemach moment are shown to be consistent with Lamb shift measurements in muonic hydrogen.
