description: Hollow-core negative curvature fibers can confine light within air core and have small nonlinearity and dispersion and high damage threshold, thereby attracting a great deal of interest in the field of hollow core fibers. However, reducing the loss of hollow-core negative curvature fibers is a serious problem. On this basis, three new types of fibers with different nested tube structures are proposed in the near-infrared spectral regions and compared in detail with a previously proposed hollow-core negative curvature fiber. We used finite-element method for numerical simulation studies of their transmission loss, bending loss, and single-mode performance, and then the transmission performance of various structural fibers is compared. We found that the nested elliptical antiresonant fiber 1 has better transmission performance than that of the three other types of fibers in the spectral range of 0.72-1.6 μm. Results show that the transmission loss of the LP01 mode is as low as 6.45*10-6 dB/km at λ = 1.06 μm. To the best of our knowledge, the record low level of transmission loss of hollow-core antiresonant fibers with nested tube structures was created. In addition, the nested elliptical antiresonant fiber 1 has better bending resistance, and its bending loss was below 2.99*10-2 dB/km at 5 cm bending radius.

description: We describe here a quantum simulator of extended bipartite Hubbard model with broken sublattice symmetry. The simulator consists of a structured lateral gate confining two dimensional electrons in a quantum well into artificial minima arranged in a hexagonal lattice. The sublattice symmetry breaking is generated by forming an artificial triangular graphene quantum dot (ATGQD) with zigzag edges. The resulting extended Hubbard model generates tunable ratio of tunneling strength to electron-electron interactions and of sublattice symmetry with control over shape. The validity of the simulator is confirmed for small systems using mean-field and exact diagonalization many-body approaches which show that the ground state changes from a metallic to an antiferromagnetic (AF) phase by varying the distance between sites or depth of the confining potential. The one-electron spectrum of these triangular dots contains a macroscopically degenerate shell at the Fermi level. The shell persists at the mean-field level for weak interactions (metallic phase) but disappears for strong interactions, in the AF phase. We determine the effects of electron-electron interactions on the ground state, the total spin, and the excitation spectrum as a function of filling of the ATGQD. We find that the half-filled charge neutral shell leads to a partially spin polarized state in both metallic and AF regimes in accordance with Liebs theorem. In both regimes a relatively large gap separates the spin polarized ground state to the first excited many-body state at half filling of the degenerate shell. By adding or removing an electron, this gap drops dramatically, and alternate total spin states emerge with energies nearly degenerate to a spin polarized ground state.

description: The Gros Ventre are native to the plains of North America. The name “Gros Ventre” is a French interpretation of their sign language, and translates to “large belly”. This Algonkian-speaking, historically nomadic people refer to themselves as A’ani, meaning “white-Clay People”, and are also known by the Blackfoot name Atsina. In the late 1880’s the Gros Ventre, along with the Assiniboin, were relocated to Fort Belknap Reservation in northern Montana. This entry focuses around the time of 1835-1885, with tribal territory centering around the Milk River, and the Belknap Reservation representing a small portion of Gros Ventre held land. Principal ethnographic authorities use fieldwork, informant accounts, and primary documents to reconstruct Gros Ventre life prior to 1885, which marked the end of the buffalo era and the beginning of consistent missionary contact. The Gros Ventre were traditionally comprised of about 12 bands, each led by a respective chief who was distinguished in war and recognized as the band’s leader. Each band also had a Flat Pipe and a Feathered Pipe Keeper, both of whom served as religious leaders while also possessing political influence. The bands would periodically come together as a tribal unit, which was led by a tribal leader. Ceremonial organization cut across band organization, and most religious ceremonies were held at the tribal level. Gros Ventre political and religious life were interwoven, and this entry considers the religious group to be coterminous with the society at large. Gros Ventre religious beliefs included a Supreme Being, who was considered to be the ultimate ruler and controller of all other supernatural beings, as well as the Earth and its inhabitants. The Supreme Being ranked highest in importance; he was always invoked first and received first offerings. Also present in the superntatural realm were ghosts and ancestral spirit helpers, as well as other non-human supernatural beings like Bha’a, the storm ruler or the thunderbird.
On the diversity of mixing and helium core masses of B-type dwarfs from gravity-mode asteroseismology

description: The chemical evolution of the Galaxy is largely guided by the yields from massive stars. Their evolution is heavily influenced by their internal mixing, allowing the stars to live longer and yield a more massive helium core at the end of their main-sequence evolution. Asteroseismology is a powerful tool for studying stellar interiors by providing direct probes of the interior physics of the oscillating stars. This work revisits the recently derived internal mixing profiles of 26 slowly pulsating B stars observed by the Kepler space telescope, in order to investigate how well the mixing profiles can in fact be distinguished from one another as well as provide predictions for the expected helium core masses obtained at the end of the main-sequence evolution. We find that for five of these stars the mixing profile is derived unambiguously, while the remaining stars have at least one other mixing profile which explains the oscillations equally well. Convective penetration is preferred over exponential diffusive overshoot for ~55% of the stars, while stratified mixing is preferred in the envelope (~39%). We estimate the expected helium core masses obtained at the end of the main-sequence evolution and find them to be highly influenced by the estimated amount of mixing occurring in the envelopes of the stars.

description: Process capability indices are very important process quality assessment tools in automotive industries. The common process capability indices (PCIs) Cp, Cpk , Cpm are widely used in practice. The use of these PCIs based on the assumption that process is in control and its output is normally distributed. In practice, normality is not always fulfilled. Indices developed based on normality assumption are very sensitive to non- normal processes. When distribution of a product quality characteristic is non-normal, Cp and Cpk indices calculated using conventional methods often lead to erroneous interpretation of process capability. In the literature, various methods have been proposed for surrogate process capability indices under non normality but few literature sources offer their comprehensive evaluation and comparison of their ability to capture true capability in non-normal situation. In this paper, five methods have been reviewed and capability evaluation is carried out for the data pertaining to resistivity of silicon wafer. The final results revealed that the Burr based percentile method is better than Clements method. Modelling of non-normal data  and  Box-Cox  transformation method using  statistical software (Minitab 14)  provides reasonably good result  as they are very promising  methods for non –normal and moderately skewed  data (Skewness ≤ 1.5).

description: The NASA K2 mission, salvaged from the hardware failures of the Kepler telescope, has continued Kepler's planet-hunting success. It has revealed nearly 500 transiting planets around the ecliptic plane, many of which are the subject of further study, and over 1000 additional candidates. Here we present the results of an ongoing project to follow-up and statistically validate new K2 planets, in particular to identify promising new targets for further characterization. By analyzing the reconnaissance spectra, high-resolution imaging, centroid variations, and statistical likelihood of the signals of 91 candidates, we validate 60 new planets in 46 systems. These include: a number of planets amenable to transmission spectroscopy (K2-384 f, K2-387 b, K2-390 b, K2-403 b, and K2-398 c), emission spectroscopy (K2-371 b, K2-370 b, and K2-399 b), and both (K2-405 b and K2-406 b); several systems with planets in or close to mean motion resonances (K2-381, K2-398) including a compact, TRAPPIST-1-like system of five small planets orbiting a mid-M dwarf (K2-384); an ultra-short period sub-Saturn in the hot Saturn desert (K2-399 b); and a super-Earth orbiting a moderately bright (V=11.93), metal-poor ([Fe/H]=-0.579+/-0.080) host star (K2-408 b). In total we validate planets around 4 F stars, 26 G stars, 13 K stars, and 3 M dwarfs. In addition, we provide a list of 37 vetted planet candidates that should be prioritized for future follow-up observation in order to be confirmed or validated.

description: The Ethiopian industrial development strategy is characterized by export-led and labor intensive industrialization. The country is emerging as the most important investment destination in its apparel sector. Thought this sector is expected to generate more income from the export market, its export earnings remain trivial mainly due to the inefficient organizational resource utilization. One of the competent techniques that help companies to efficiently improve the use of their resources to increase their profit is linear programming. In apparel manufacturing firms, efficient use of materials such as fabrics and sewing threads and processing time at different stages of production as well as minimization of labor and materials cost are necessary to enhance their profitability. Cutting, sewing, and finishing operations deserve more attention for apparel process optimization. However, the issue of proper resource allocation remains an unsolved problem within the Ethiopian apparel industry. The aim of this research is to devise efficient resource utilization mechanism for Ethiopian apparel sector to improve their resource utilization and profitability, taking one of the garment factories engaged in the export market as a case study.  Five types of products the company is currently producing, the amount of resources employed to produce each unit of the products, and the value of profit per unit from the sale of each products have been collected from the case company. The monthly availability of resources utilized and the monthly production volume of the five products have also been collected from the company. The data gathered was mathematically modeled using a linear programming technique, and solved using MS-Excel solver. The findings of the study depicts that all of the organizational resources are severely underutilized. This research proved that the resource utilization of the case company can be improved from 46.41% of the current resource utilization to 98.57%. This indicates that the new solution provides very significantly improvement in organizational resource utilization. At the same time, with the new solution, the total profit per month of the case company can be increased from 365,699 birr per month to 897,844 birr per month (i.e., with an increment of 145.5%). Finally, it is concluded that this remarkable profit increment of the company can certainly enhance its global competitiveness.

description: Calculations of the diffusion of a Au adatom on the dimer reconstructed Si(100)-2x1 surface reveal an interesting mechanism that differs significantly from a direct path between optimal binding sites, which are located in between dimer rows. Instead, the active diffusion mechanism involves promotion of the adatom to higher energy sites on top of a dimer row and then fast migration along the row, visiting ca. a hundred sites at room temperature, before falling back down into an optimal binding site. This top-of-row mechanism becomes more important the lower the temperature is. The calculations are carried out by finding minimum energy paths on the energy surface obtained from density functional theory within the PBEsol functional approximation followed by kinetic Monte Carlo simulations of the diffusion over a range of temperature from 200 K to 900 K. While the activation energy for the direct diffusion mechanism is calculated to be 0.84 eV, the effective activation energy for the indirect mechanism is on average 0.56 eV.

New Solar Flare Calcium Abundances with no Surprises: Results from the SMM Bent Crystal Spectrometer

description: The calcium abundance in flare plasmas is estimated using X-ray spectra from the Solar Maximum Mission Bent Crystal Spectrometer (BCS) during the decays of 194 flares (GOES classifications from B6.4 to X13) occurring between 1980 and 1989. Previous work by Sylwester et al. found that the abundance varied from flare to flare. That analysis is improved on here using updated instrument parameters and by including all calcium lines viewed by the BCS instead of only the resonance line, so greatly enhancing the photon count statistics. The abundance variations are confirmed with the average abundance, $A({\rm Ca})$ (expressed logarithmically with $A({\rm H}) = 12$), equal to $6.77 \pm 0.20$ for 194 flares (141 of which are new in this study). This range corresponds to factors of between 1.7 and 7.2 larger than the photospheric abundance and so our results are in line with a ``FIP" (first ionization potential) effect whereby low-FIP elements like Ca (FIP = 6.11~eV) have enhanced coronal abundances. The Ca flare abundance is uncorrelated with solar activity indices, but weak correlations are suggested with GOES flare class and duration (larger $A({\rm Ca})$ for smaller and shorter flares). The ponderomotive force theory of Laming explaining the FIP effect gives a range of parameters within which our estimates of $A({\rm Ca})$ agree with the theory. However, this then gives rise to disagreements with previous estimates of the flare silicon and sulfur abundances, although those of argon and iron are in good agreement. Small adjustments of the theory may thus be necessary.

description: Fait réjouissant, la transition énergétique allemande, ou Energiewende, fait l’objet d’intenses activités de recherche. Nous disposons à présent d’estimations fiables sur les technologies, les coûts pour les consommateurs finaux et la société, et les conséquences auxquelles on peut s’attendre pour l’environnement et la santé. Nous savons combien les émissions de CO2 ont déjà été réduites grâce à la transition énergétique, et comment procéder pour les réduire encore davantage. Il existe également un certain nombre d’études scientifiques traitant des effets de l’expansion des énergies renouvelables sur la protection de la nature et des espèces. Une question reste cependant peu examinée : quels sont les effets de la transition énergétique sur la société ? Il est surprenant que nous en sachions si peu sur ce sujet. Les spécialistes s’accordent depuis longtemps à dire que les dimensions du développement durable ne sont pas seulement économiques et écologiques, mais aussi sociales. Il est donc tout aussi important d’analyser les effets de la transition énergétique sur la société que sur l’économie ou l’écologie. Il est grand temps de donner un fondement empirique solide à la question de la durabilité sociale. L’Institute for Advanced Sustainability Studies (IASS) a mené, avec l’Institut RWI-Leibniz pour la recherche économique, une étude auprès de plus de 7 500 ménages. Avec le « Baromètre de la durabilité sociale de la transition énergétique allemande 2017 », nous présentons aujourd’hui les résultats pour la première fois.

description: We use a near-threshold parameterization with explicit inclusion of the Castillejo-Dalitz-Dyson poles, which is more general than the effective range expansion, to study the bottomonium-like states $Z_b(10610)$ and $Z_b(10650)$. In terms of the partial-wave amplitude, we fit the event number distribution of $B^{(*)}\bar B^*$ system to the experimental data for these resonances from Belle Collaboration. The data could be described very well in our method, which supports the molecular interpretation. Then the relevant physical quantities are obtained, including the $B^{(*)}\bar{B}^*$ scattering length ($a$), effective range ($r$), and residue squared ($γ_s^2$) of the pole in the complex plane. In particular, we find the compositeness can range from about 0.4 up to 1 for the $B\bar B^*$ ($B^*\bar B^*$) component in the resonance $Z_b(10610)$ ($Z_b(10650)$).

description: The Lengua are native to the Paraguayan Chaco of South America. In 1889 the Church of England South American Missionary Society began to work in the Lengua’s native territory as missionary Barbrooke Grubb began a 20 year residence among the Lengua living by the Chaco bank of the Paraguay River. Although Grubb was not an anthropologist, his detailed field notes from this time have become the principal ethnographic authority on the Lengua. This entry focuses on the Lengua band in contact with the mission around the time of 1889. At this time, the Lengua were living in autonomous bands and villages with little social distinctions; chiefs only held rule when needed for the common good (such as in times of war). Magical-practitioners were present, with their main task to protect the village from supernatural evils. These practitioners could also affect the weather and foretell future events. The Lengua supernatural beings included a vague and otiose creator deity (symbolized by a beetle), kilyikhama (malignant spirits), aphangak (departed souls of men, who would stay around for about a month after death, then traveling to the afterlife), and departed souls of lower creations. Various feasts and religious celebrations were held throughout the year. Religion does not exist within a distinct sphere but rather permeates all aspects of life; this entry considers the religious group to be coterminous with Lengua society.

description: We investigate the convergence properties of finite-temperature perturbation theory by considering the mathematical structure of thermodynamic potentials using complex analysis. We discover that zeros of the partition function lead to poles in the internal energy and logarithmic singularities in the Helmholtz free energy which create divergent expansions in the canonical ensemble. Analysing these zeros reveals that the radius of convergence increases for higher temperatures. In contrast, when the reference state is degenerate, these poles in the internal energy create a zero radius of convergence in the zero-temperature limit. Finally, by showing that the poles in the internal energy reduce to exceptional points in the zero-temperature limit, we unify the two main mathematical representations of quantum phase transitions.

description: The discrepancy between the bright theoretical projections for two-dimensional (2D) Janus structures and the lack of experimental realisation of these structures motivated us to study the effect of structural disorder on the stability of MoSSe, SnSSe, PtSSe, In2SSe and GaInSe2. The calculation results demonstrate that the difference between metal-sulfur and metal-selenium bonds makes Janus structures frustrated and less energetically favourable than less ordered allotropes of the same compounds. This result explains the difficulties encountered in experimental fabrication of these materials. In the bulk, there is an additional contribution to the total energy from dipole-dipole interactions between layers with a Janus structure that can overcome the energetic cost of structural frustration in layers for compounds with sufficiently large dipole moments. However, the entropic contribution to the free energy decreases the favourability of the ordered Janus structure. The calculation results are used to make recommendations to enable the discovery and synthesis of 2D materials with Janus structures.

description: Nanobem is a Matlab toolbox for the solution of Maxwell's equations for nanophotonic systems and the computation of resonance modes, sometimes also referred to as quasinormal modes or resonance states. It is based on a Galerkin scheme for the boundary element method, using Raviart-Thomas shape elements for the representation of the tangential electromagnetic fields at the particle boundary. The toolbox is written in an object-oriented manner with the focus on clarity rather than speed, and has been developed and tested for small to intermediate problems with a few thousand boundary elements. The computation of the resonance modes uses the contour integral method of Beyn.

description: Particle acceleration in dielectric microstructures powered by infrared lasers, or "dielectric laser acceleration" (DLA), is a promising area of advanced accelerator research with the potential to enable more affordable and higher-gradient accelerators for energy frontier science and a variety of other applications. DLA leverages well-established industrial fabrication capabilities and the commercial availability of tabletop lasers to reduce cost, with axial accelerating fields in the GV/m range. Desirable luminosities would be obtained by operating with very low charge per bunch but at extremely high repetition rates. And as a consequence of its unique operating parameter regime, coupling of the laser to the accelerator can potentially be in the 50\% range and with low beamstrahlung energy loss due at the interaction point, making DLA a promising approach for a future multi-TeV linear collider.

description: Quality infrastructure is developed on state level and covers standardization, accreditation, metrology and certification. It is a “hard” part of quality infrastructure. On the regional level there are “soft” factors such as quality level in organizations, education and training level, state support and so on. The key role of quality infrastructure is to be a basis for all quality improvement actions on lower i.e. organizational levels. It is also a basis for regional development. The influence of quality infrastructure on regional development has not been investigated enough, especially in transition states. That serves as motivation to the authors trying to define an integrative model of quality infrastructure and regional development. This model is partially verified in Bosnia and Hercegovina, being an example of transition economy. A part of the research has been presented in the paper.

Aweikoma also known as “Xokleng”, “Kaingáng”, “Caingang”

description: The Aweikoma traditionally inhabited a large area in what is now the state of Santa Catarina, Brazil, and lived in small, exogamous patrilineal clans. These highly mobile bands were led by chiefs, whose authority was limited. In 1914 the Aweikoma were pacified by the Brazilian Government and relocated to Duque de Caxias Reservation (near Ibirama). This entry focuses on the Aweikoma living on the reservation around the time of 1932, when the principal ethnographic authority, anthropologist Jules Henry, began a two-year ethnographic study in the area. This entry primarily relies on Henry’s field work, which broadly covers Aweikoma life but provides somewhat limited information on the religious realm of life. Traditional Aweikoma religious beliefs and practices were able to be documented as the Brazilian government resisted attempts to establish missions (Henry, Benedict, and Kraus, 1941: xvi). These beliefs involve a variety of supernatural beings, including the spirits of deceased humans (referred to as ghost-souls or kuplêng), and monsters (Kuchágn Yunggí Wangdjó Yóin and Véin). The monsters, ghost-soul, and spirits of the natural world are collectively called nggïyúdn. According to Henry, shamans served as religious practitioners in former times, but no shamans were still living during the time of his visit. For the Aweikoma, religion does not exist within its own distinct sphere of life, but rather, is bound up with the functioning of society as a whole. Consequently, this entry considers the religious group to be coterminous with Aweikoma society as a whole.
Homologous compact major blowout-eruption solar flares and their production of broad CMEs

description: We analyze the formation mechanism of three homologous broad coronal mass ejections (CMEs) resulting from a series of solar blowout-eruption flares with successively increasing intensities (M2.0, M2.6, and X1.0). The flares originated from active region NOAA 12017 during 2014 March 28-29 within an interval of approximately 24 hr. Coronal magnetic field modeling based on nonlinear-force-free-field extrapolation helps to identify low-lying closed bipolar loops within the flaring region enclosing magnetic flux ropes. We obtain a double flux rope system under closed bipolar fields for the all the events. The sequential eruption of the flux ropes led to homologous flares, each followed by a CME. Each of the three CMEs formed from the eruptions gradually attain a large angular width, after expanding from the compact eruption-source site. We find these eruptions and CMEs to be consistent with the 'magnetic-arch-blowout' scenario: each compact-flare blowout eruption was seated in one foot of a far-reaching magnetic arch, exploded up the encasing leg of the arch, and blew out the arch to make a broad CME.

Dark Matter and Muon $g-2$ Anomaly via Scale Symmetry Breaking

description: The Standard Model (SM) without the Higgs mass term is scale invariant. Gildener and Weinberg generalized the scale invariant standard model (SISM) by including the multiplication of scalars in quartic forms. They pointed out that along the flat direction only one scalar -- called the scalon -- is classically massless and all other scalars are massive. Here we choose a SISM with one scalon and one heavy scalar and extend that further respecting the scale invariance by a vector-like lepton (VLL). By an appropriate choice of the flat direction, the heavy scalar enjoys the $\mathbb{Z}_2$ symmetry and is assumed as DM particle. The scalon connects the visible and dark sector via the Higgs-portal and by interacting with both the muon lepton and the VLL. The VLL is charged under $U(1)_Y$ and interacts with $γ/Z$ bosons. We show that the model correctly accounts for the observed dark matter (DM) relic abundance in the universe, while naturally evading the current and future bounds from direct detection (DD) experiments. Moreover, the model is capable to explain the $(g-2)_μ$ anomaly observed in Fermilab. We also show a feature in SISM scenarios which is not present in other Higgs-portal models; despite having the Higgs-portal term $|H|^2 s^2$ ($s$ being the scalon) in SISM, the effective potential after the electroweak symmetry breaking lacks an important expected vertex $h s^2$. This property immediately forbids the tree-level invisible Higgs decay $h\to ss$ and the one-loop Higgs decay $h\to μ^+ μ^-$.

description: IASS Discussion Paper
description: Die Studie arbeitet gesellschaftliche Strukturdeterminanten und -dynamiken sowie Frames, Bedingungsverhältnisse, Trade-offs, Kopplungen und Eigendynamiken von Energiewende und – in deutlich verkürzter Form – von Energiekonflikten und von nachhaltiger Entwicklung heraus, thematisiert die Zusammenhänge dieser drei Sphären, und versucht auf dieser Grundlage, Entwicklungsmuster und Erfolgschancen der Energiewende abzuschätzen. Als eine soziotechnische Transformation verlangt die Energiewende die Realisierung eine Vielzahl von Maßnahmen in praktisch allen Teilsystemen der Gesellschaft, die ihrerseits vielfältige Konflikte generieren. Von daher ist die Energiewende in ihrer Entwicklung nicht akteurspezifisch steuerbar und eine erwünschte konsistente, ihre Nachhaltigkeit gewährleistende, produktive Konflikte nutzende und unproduktive Konflikte vermeidende Energiewendepolitik allenfalls ansatzweise zu erwarten. Prinzipiell ist eine die Energiewende konsequent vorantreibende Interaktionsdynamik der sie prägenden Einflussfaktoren zwar denkbar und möglich, in der Praxis ist hingegen eine die Energiewende eher erratisch antreibende Interaktionsdynamik aus einer Kombination von für sie vorteilhaften und nachteiligen Einflussfaktoren zu beobachten.

description: In the context of general relativity, both energy and linear momentum constraints lead to the same equation for the evolution of the speed of free localized particles with fixed proper mass and structure in a homogeneous and isotropic Friedmann-Lemaître-Robertson-Walker universe. In this paper we extend this result by considering the dynamics of particles and fluids in the context of theories of gravity nonminimally coupled to matter. We show that the equation for the evolution of the linear momentum of the particles may be obtained irrespective of any prior assumptions regarding the form of the on-shell Lagrangian of the matter fields. We also find that consistency between the evolution of the energy and linear momentum of the particles requires that their volume-averaged on-shell Lagrangian and energy-momentum tensor trace coincide ($\mathcal L_{\rm on-shell}=T$). We further demonstrate that the same applies to an ideal gas composed of many such particles. This result implies that the two most common assumptions in the literature for the on-shell Lagrangian of a perfect fluid ($\mathcal L_{\rm on-shell}=\mathcal{P}$ and $\mathcal L_{\rm on-shell}=-ρ$, where $ρ$ and $\mathcal{P}$ are the proper density and pressure of the fluid, respectively) do not apply to an ideal gas, except in the case of dust (in which case $T=-ρ$).
