description: The C02DGM detailed global model is used to characterize electric thrusters breathing CO2 . The latter are of interest to Mars and Venus artificial satellites and spacecraft propulsion in their vicinity C02DGM results are illustrated by diagrams giving the composition of the plasma components and ionization percentages containing isothermal, isobaric and isoenergetic curves which describe the thruster functioning for various regimes. The model incorporates data concerning detailed structure and reactions involving oxygen and carbon species and molecules composed from them, including their ions. Thus, spectral lines intensity of the main thruster constituents is obtained, allowing for optical emission spectroscopy diagnostics.

description: Lack of timeliness and capacity are seen as fundamental problems that jeopardise healthcare delivery systems everywhere. Many believe the shortage of medical providers is causing this timeliness problem. This action research presents how one doctor implemented the theory of constraints (TOC) to improve the throughput (quantity of patients treated) of his ophthalmology imaging practice by 64% in a few weeks with little to no expense. The five focusing steps (5FS) guided the TOC implementation – which included the drum-buffer-rope scheduling and buffer management – and occurred in a matter of days. The implementation provided significant bottom-line results almost immediately. This article explains each step of the 5FS in general terms followed by specific applications to healthcare services, as well as the detailed use in this action research. Although TOC successfully addressed the practice problems, this implementation was not sustained after the TOC champion left the organisation. However, this drawback provided valuable knowledge. The article provides insightful knowledge to help readers implement TOC in their environments to provide immediate and significant results at little to no expense.
title: Towards a Theoretically Informed Practice: A Study of Koru Mindfulness Teachers in Higher Education

description: Mindfulness is gaining acceptance and use in many sectors of society, including education. As a pedagogical tool, mindfulness is one of many contemplative practices used within Contemplative Education (CE) to enhance student learning. Mindfulness is also part of the growing number of mindfulness-based interventions (MBIs). Within Higher Education Institutions (HEIs), MBIs are increasingly accessible through student services and other well-being initiatives to assist students in navigating academic life. The growing body of research carried out across a wide variety of disciplines and diverse cultural contexts points to the increasing global use of mindfulness in higher education (HE). However, research on mindfulness teachers is relatively limited compared to research on students. This study aims to inform, empower, and challenge current practice and teacher training in mindfulness by providing an investigation into the lived experience of a group of mindfulness teachers in higher education. This study investigates 12 participants and the researcher. Participants were Koru Mindfulness teachers working in higher education. Koru Mindfulness is a stand-alone mindfulness curriculum designed for 18–28-year-olds. All participants were trained Koru Mindfulness teachers working in HEIs. The study used the Transcendental Method for Research with Human Subjects (TMRHS). TMRHS is a qualitative research method that draws from thematic analysis and is grounded in the phenomenology of Husserl and the critical realist Lonergan's theory of cognition. TMRHS guides participants and researchers through a systematic reflective process. Results indicated that mindfulness teachers go through an identifiable process by which they both claim and embody the role of mindfulness teachers. Underpinning mindfulness teachers' decision to teach is a desire to reduce suffering and increase student well-being. They are informed and influenced by their personal contemplative experiences, values, and spirituality. Archer's morphogenic approach provided a theoretical framework to inform understanding of the proposed identifiable process of claiming and embodying the role of mindfulness teacher. This theoretically informed analysis at the intersection of higher education and mindfulness teaching provides a framework to consider research and practice and possible avenues for impact. However, at the core of this study is an individual's agency and decision-making. The personal aspect of teaching is paramount when considering risk reduction, enhancing best practices, and responding to some of the most ardent criticisms of mindfulness teaching.

description: 4CDGM, a volume averaged detailed global model with the four initial components 0, 02 , N, N2 can analyse the functioning of air-breathing electric thrusters to foresee the plasma constitution and to diagnose it by OES. 4CDGM may also evaluate the atmospheric remnants in altitudes exceeding the Karman line set in about 100 km altitude on the basis of existing empirical models. In order to support air-breathing thrusters, 4CDGM provides Plasma Component Composition diagrams, Functioning Diagrams and also theoretical spectra emission line intensities, thus allowing for OES diagnostics. Such diagrams and theoretical spectra are presented and discussed herewith.

FLIGHT EXPERIMENT

description: The flight in hypersonic conditions implies important challenges for the vehicle development concerning the thermal protection of the external structures, especially in the case of sharp leading edges, where the short standoff distance of the forming shock waves typically determines severe aero-thermal loads. In the framework of the HIFLIERl flight research experiment, the DLR Institute of Structures and Design, in collaboration with the High Enthalpy Flow Diagnostics Group at the University of Stuttgart, is responsible for setting up the so-called FinEx!I module of the sounding rocket, for flight testing of the transpiration cooling technology applied to porous ceramic matrix composite structures as a possible approach for thermal management of sharp leading edges in hypersonic regime. For this purpose, the module will house four fins, whose leading edge is made of an inhouse-developed porous C/C-SiC material, connected to a gas system feeding nitrogen for the transpiration cooling application. The present paper gives an overview of the module design, supported by efficient nuruerical modelling to estimate the effect of the transpiration cooling, and the pre-flight activities, including the fins manufacturing and pre-flight characterization as well as the rocket module setup.

description: Recent experimental progress using ultracold gases in optical lattices necessitates a quantitative theoretical description for a significant number of bosons. In the present paper, we investigate if time-dependent semiclassical initial value methods, with propagators expressed as integrals over phase space using classical trajectories, is suitable to describe interacting bosons, concentrating on a single mode. Despite the nonlinear contribution from the self-interaction, the corresponding classical dynamics allows for a largely analytical treatment of the semiclassical propagator. We find that the Herman-Kluk (HK) propagator conserves unitarity in the semiclassical limit ($n\to\infty$), but a decay of the norm is seen for low $n$. The frozen Gaussian approximation (FGA, i.e. HK with unit prefactor) is explicitly shown to violate unitarity in the present system for non-vanishing interaction strength, even in the semiclassical limit. Furthermore, we show by evaluating the phase space integral in steepest descent approximation, that the HK propagator reproduces the exact spectrum correctly in the limit $n\to \infty$. An error is, however, incurred in next-to-next-to-leading order (small parameter $1/n$), as seen upon numerical evaluation of the integral or by considering finite $n$ corrections to steepest descent. The FGA, in contrast, is only accurate to lowest order, and an erroneous next-to-leading order term in the energy spectrum was found analytically. Finally, as an example application, we study the dynamics of wave packets by computing the time evolution of the Wigner function. While the often-used truncated Wigner approximation cannot capture any interferences present in the exact quantum mechanical solution (known analytically), we find that the HK approach, despite also using classical information only, reproduces the salient features of the exact solution correctly.

description: We theoretically study intrinsic superconductivity in doped Dirac semimetals. Dirac semimetals host bulk Dirac points, which are formed by doubly degenerate bands, so the Hamiltonian is described by a $4 \times 4$ matrix and six types of $k$-independent pair potentials are allowed by the Fermi-Dirac statistics. We show that the unique spin-orbit coupling leads to characteristic superconducting gap structures and $d$ vectors on the Fermi surface and the electron-electron interaction between intra and interorbitals gives a novel phase diagram of superconductivity. It is found that when the inter-orbital attraction is dominant, an unconventional superconducting state with point nodes appears. To verify the experimental signature of possible superconducting states, we calculate the temperature dependence of bulk physical properties such as electronic specific heat and spin susceptibility and surface state. In the unconventional superconducting phase, either dispersive or flat Andreev bound states appear between point nodes, which leads to double peaks or single peak in the surface density of states, respectively. As a result, possible superconducting states can be distinguished by combining bulk and surface measurements.

description: This study has demonstrated the development of a novel patterned porous polymer (polyHIPE) material suitable to the requirements of neural lineage responses during peripheral nerve regeneration. These materials display mechanical properties similar to peripheral nerve tissue and retain sufficient porous to allow perfusion. Modifications to the porous surface of the polyHIPE via series of micropatterned topographies demonstrate control over nerve outgrowth in the direction of physical cues. These data demonstrate the biocompatibility of these patterned polyHIPEs and their suitability for the further development for peripheral nerve regeneration.

description: The aim of this study is to present a numerical framework for the development of transpiration cooled rocket combustion chambers based on the commercial CFD software ANSYS CFX. The framework couples the hot gas flow domain and the coolant reservoir domain with the porous domain. The numerical setup is applied to an exemplary virtual transpiration cooled LOx/LH2 main stage rocket engine. Two different approaches modeling the hot gas flow with non-reactive flow and reactive flow are introduced and evaluated. The described setup was used for a parametric study to identify desirable properties for the porous material.

EMISSION

description: A design optimization methodology is implemented in a multidisciplinary aircraft design framework to optimize a regional very-high aspect ratio truss-braced wing aircraft layout considering both cost and emission requirements. A detailed emission model is incorporated to calculate the emission masses and temperature responses due to the engine emissions. Since the design variables include the mission parameters, namely the cruise altitude and cruise Mach number, an engine sizing module based on the thermodynamic cycle is integrated into the design. The results show that the optimum configuration for emission and cost are quietly different. The emission objective drives the design toward lower cruise altitudes and Mach numbers (i.e. 20 [kft] and Mach 0.4), while the cost objective drives the design toward higher Mach numbers and altitudes. The reason is found to be the mechanism by which these emissions are formed and affect the temperature rise, particularly the altitude at which these emissions are created. At the end, the effect of engine bypass ratio, and mission profile (cruise altitude and cruise speed) are analyzed.

description: A framework for high-fidelity wing structure analysis, sizing and optimization using the finite element method is developed. This framework, which can be applied to both cantilever (CLW) and truss-braced wings (TEW), takes into account the strength, stiffness and stability criteria. The strength sizing is based on shell and beam element properties optimization subjected to different load cases. For the stiffness sizing, a numerical methodology for converting the shell model to a beam model is developed and implemented. The stability sizing is based on engineering methods, and the strut section is sized to withstand compressive loads. The developed methodology is implemented for the sizing of the wing structure of CLW and TEW. Results show that the structural weight of a very high aspect ratio (aspect ratio of 20) truss-braced wing is higher than the high aspect ratio ( aspect ratio of 11) cantilever wing by nearly 30% when sized for strength requirements. On the other hand, the flutter requirements have not affected the CLW design, while the outboard section of the TEW required more stiffness to pass this requirement.

description: It is shown by the Wilson numerical renormalization group method that a strongly correlated impurity with a crystalline-electric-field singlet ground state in the f^2-configuration exhibits an anomalous local Fermi liquid state in which the static magnetic susceptibility remains an uncorrelated value while the NMR relaxation rate is enhanced in proportion to the square of the mass enhancement factor. Namely, the Korringa-Shiba relation is apparently broken. This feature closely matches the anomalous behaviors observed in UPt_3, i.e., the coexistence of an unenhanced value of the Knight shift due to quasiparticles contribution (the decrease across the superconducting transition) and the enhanced relaxation rate of NMR. Such an anomalous Fermi liquid behavior suggests that the Fermi liquid corrections for the susceptibility are highly anisotropic.

description: We investigate the $ΛΛ$ and $K^-p$ intensity correlations in high-energy heavy-ion collisions. First, we examine the dependence of the $ΛΛ$ correlation on the $ΛΛ$ interaction and the $ΛΛ$ pair purity probability $λ$. For small $λ$, the correlation function needs to be suppressed by the $ΛΛ$ interaction in order to explain the recently measured $ΛΛ$ correlation data. By comparison, when we adopt the $λ$ value evaluated from the experimentally measured $Σ^0/Λ$ ratio, the correlation function needs to be enhanced by the interaction. We demonstrate that these two cases correspond to the two analyses which gave opposite signs of the $ΛΛ$ scattering length. Next, we discuss the $K^-p$ correlation function. By using the local $\bar{K}N$ potential which reproduces the kaonic hydrogen data by SIDDHARTA, we obtain the $K^-p$ correlation function. We find that the $K^-p$ correlation can provide a complementary information with the $K^{-}p$ elastic scattering amplitude.

description: We have used the vortex filament method to numerically investigate the interactions between pairs of quantized vortex rings that are initially traveling in the same direction but with their axes offset by a variable impact parameter. The interaction of two circular rings of comparable radii produce outcomes that can be categorized into four regimes, dependent only on the impact parameter; the two rings can either miss each other on the inside or outside, or they can reconnect leading to final states consisting of either one or two deformed rings. The fraction of of energy went into ring deformations and the transverse component of velocity of the rings are analyzed for each regime. We find that rings of very similar radius only reconnect for a very narrow range of the impact parameter, much smaller than would be expected from geometrical cross-section alone. In contrast, when the radii of the rings are very different, the range of impact parameters producing a reconnection is close to the geometrical value. A second type of interaction considered is the collision of circular rings with a highly deformed ring. This type of interaction appears to be a productive mechanism for creating small vortex rings. The simulations are discussed in the context of experiments on colliding vortex rings and quantum turbulence in superfluid helium in the zero temperature limit.

description: The EPW (Electron-Phonon coupling using Wannier functions) software is a Fortran90 code that uses density-functional perturbation theory and maximally localized Wannier functions for computing electron-phonon couplings and related properties in solids accurately and efficiently. The EPW v4 program can be used to compute electron and phonon self-energies, linewidths, electron-phonon scattering rates, electron-phonon coupling strengths, transport spectral functions, electronic velocities, resistivity, anisotropic superconducting gaps and spectral functions within the Migdal-Eliashberg theory. The code now supports spin-orbit coupling, time-reversal symmetry in non-centrosymmetric crystals, polar materials, and $\mathbf{k}$ and $\mathbf{q}$-point parallelization. Considerable effort was dedicated to optimization and parallelization, achieving almost a ten times speedup with respect to previous releases. A computer test farm was implemented to ensure stability and portability of the code on the most popular compilers and architectures. Since April 2016, version 4 of the EPW code is fully integrated in and distributed with the Quantum ESPRESSO package, and can be downloaded through QE-forge at http://qe-forge.org/gf/project/q-e.

description: This paper proposes a novel transitioning e VTOL aircraft concept utilizing distributed underwing ducted fans with a specially designed undercambered airfoil presented as the \'Maldonado-Hicks\' airfoil. It is hypothesized that this concept where the airfoil is blended intothe fan on the aft portion of the airfoil, referred to as the \'FanFoil\' concept, is aerodynamicallysuperior to mounting the fans over the wing. This is due to the ability to recess and partially hide the fans underneath the wing, such that the fans are not entirely visible in forward flightwhen looking at the wing from the front. It is expected that this \'FanFoil\' technique reduces the form drag of the wing with distributed fans. In this initial study, computational fluid dynamic (CFD) simulations are performed on the MaldonadoHicks airfoil which represent a two-dimensional section of the e VTOL wing at the cruise conditions; Mach 0.22 (260 km/h) and Reynolds number of 6.5xlOG The lift and drag coefficients are computed in order to get an understanding of the cruise angle of attack and design lift coefficient that maximizes aerodynamic efficiency as quantified by the lift-toldrag ratio, LID. Open vehicle sketch pad (VSP) is also used to perform a low-fidelity CFD analysis of the clean eVTOL configuration. The base drag coefficient, Cn, is estimated\'as 0.018. Finally, an idealized steady-state analytical mission analysis is completed for a hypothetical maximum-range mission for a 5-passenger e VTOL concept. Based on power and energy consumption calculations, it is estimated that thisaircraft concept attains a maximum range of 290 km with a 300 kW-h size lithium polymer battery and a usable energy of 270 kW-h.

description: We introduce the notion of a $k$-mode weakly stationary quantum process $\varrho$ based on the canonical Schrödinger pairs of position and momentum observables in copies of $L^2(\mathbb{R}^k)$, indexed by an additive abelian group $D$ of countable cardinality. Such observables admit an autocovariance map $\widetilde{K}$ from $D$ into the space of real $2k \times 2k$ matrices. The map $\widetilde{K}$ on the discrete group $D$ admits a spectral representation as the Fourier transform of a $2k \times 2k$ complex Hermitain matrix-valued totally finite measure $Φ$ on the compact character group $\widehat{D}$, called the Kolmogorov-Wiener-Masani (KWM) spectrum of the process $\varrho$. Necessary and sufficient conditions on a $2k \times 2k$ complex Hermitian matrix-valued measure $Φ$ on $\widehat{D}$ to be the KWM spectrum of a process $\varrho$ are obtained. This enables the construction of examples. Our theorem reveals the dramatic influence of the uncertainty relations among the position and momentum observables on the KWM spectrum of the process $\varrho$. In particular, KWM spectrum cannot admit a gap of positive Haar measure in $\widehat{D}$. The relationship between the number of photons in a particular mode at any site of the process and its KWM spectrum needs further investigation.

description: Objectives Current international guidelines recommend using a combination of Long-Acting Beta-Agonists and Inhaled Corticosteroids (LABA+ICS) therapy for symptomatic mild asthma. However, this change has yet to be widely implemented in the Middle East. The objective of this pilot study is to assess the feasibility (recruitment and retention rates) of conducting a future definitive RCT to investigate the effectiveness of fluticasone-vilanterol (LABA+ICS) in the management of mild asthma in adults, compared with usual care. Design This 8-month parallel two-arm pilot trial took place in the Kingdom of Bahrain. We randomly assigned 18 patients with mild asthma in a 1:1 ratio to the treatment (n=10) or usual care (n=8) arms. The treatment group received daily LABA+ICS therapy while the usual care group continued as required SABA or SABA+ICS combination. The main outcome measures were descriptors of study feasibility (recruitment and retention rates). We also compared unblinded outcome assessment of asthma control score, quality of life, and the number of asthma exacerbations experienced by patients in both arms. Results A total of 18 patients were recruited from a single primary healthcare center and randomized by remote web-based allocation into intervention (n=10) and usual care (n=8) groups. The baseline characteristics of participants did not differ significantly across the two arms at the start of the trial. Because of slow recruitment and limited funding, the study didn't meet our recruitment target but did successfully meet our retention criteria. At 32 weeks, the analysis indicated significant improvement in asthma control scores in the intervention arm (1.31 vs 2.91; 95% CI [0.72, 2.44]; P-value=0.003), but no significant differences were noted in quality-of-life scores (P-value=0.197) compared to the baseline levels. There were no significant differences in post-intervention asthma control mean score (P-value=0.361) or QoL mean score (P-value=0.337) between the two arms after adjustment for pre-intervention scores. Conclusions This pilot RCT indicates that a definitive RCT is feasible in a primary healthcare setting in Bahrain. In a definitive trial, we recommend increasing the recruitment rate by relaxing eligibility criteria, extending the timeline, and increasing the number of sites for recruitment. Additionally, outcomes of this pilot trial suggest that LABA+ICS is a feasible, acceptable, safe, and effective intervention for the management of mild asthma in a Middle Eastern context.

description: The process of fermion production in the field of a magnetic dipole on a de Sitter expanding universe is analyzed. The amplitude and probability for production of massive fermions are obtained using the exact solution of the Dirac equation written in the momentum-helicity basis. We found that the most probable transitions are those that generate the fermion pair perpendicular to the direction of the magnetic field. The behavior of the probability is graphically studied for large/small values of the expansion factor, and a detailed analysis of the probability in terms of the angle between the momenta vectors of the particle and antiparticle is performed. The phenomenon of fermion production is significant only at large expansion which corresponds to the conditions from the early Universe. When the expansion factor vanishes we recover the Minkowski limit where this process is forbidden by the simultaneous energy-momentum conservation.

description: Neurites, the long cellular protrusions that form the routes of the neuronal network are capable to actively extend during early morphogenesis or to regenerate after trauma. To perform this task, they rely on their cytoskeleton for mechanical support. In this paper, we present a three-component active gel model that describes neurites in the three robust mechanical states observed experimentally: collapsed, static, and motile. These states arise from an interplay between the physical forces driven by growth of the microtubule-rich inner core of the neurite and the acto-myosin contractility of its surrounding cortical membrane. In particular, static states appear as a mechanical traction/compression balance of these two parallel structures. The model predicts how the response of a neurite to a towing force depends on the force magnitude and recovers the response of neurites to several drug treatments that modulate the cytoskeleton active and passive properties.
Gravity at the horizon: on relativistic effects, CMB-LSS correlations and ultra-large scales in Horndeski's theory

description: We address the impact of consistent modifications of gravity on the largest observable scales, focusing on relativistic effects in galaxy number counts and the cross-correlation between the matter large scale structure (LSS) distribution and the cosmic microwave background (CMB). Our analysis applies to a very broad class of general scalar-tensor theories encoded in the Horndeski Lagrangian and is fully consistent on linear scales, retaining the full dynamics of the scalar field and not assuming quasi-static evolution. As particular examples we consider self-accelerating Covariant Galileons, Brans-Dicke theory and parameterizations based on the effective field theory of dark energy, using the \hiclass\, code to address the impact of these models on relativistic corrections to LSS observables. We find that especially effects which involve integrals along the line of sight (lensing convergence, time delay and the integrated Sachs-Wolfe effect -- ISW) can be considerably modified, and even lead to $\mathcal{O}(1000\%)$ deviations from General Relativity in the case of the ISW effect for Galileon models, for which standard probes such as the growth function only vary by $\mathcal{O}(10\%)$. These effects become dominant when correlating galaxy number counts at different redshifts and can lead to $\sim 50\%$ deviations in the total signal that might be observable by future LSS surveys. Because of their integrated nature, these deep-redshift cross-correlations are sensitive to modifications of gravity even when probing eras much before dark energy domination. We further isolate the ISW effect using the cross-correlation between LSS and CMB temperature anisotropies and use current data to further constrain Horndeski models (abridged).

description: Non-Decoupling D-Terms are an attractive possibility to enhance the tree-level mass of the standard model like Higgs boson in supersymmetric models. We discuss here for the case of a new Abelian gauge group two effects usually neglected in literature: (i) the size of the additional radiative corrections to the Higgs mass due to the presence of the new gauge coupling, and (ii) the impact of gauge kinetic mixing. It is shown that both effects reduce to some extent the positive effect of the non-decoupling D-terms on the Higgs mass.

description: The cross-Wigner distribution $W(f,g)$ of two functions or temperate distributions $f,g$ is a fundamental tool in quantum mechanics and in signal analysis. Usually, in applications in time-frequency analysis $f$ and $g$ belong to some modulation space and it is important to know which modulation spaces $W(f,g)$ belongs to. Although several particular sufficient conditions have been appeared in this connection, the general problem remains open. In the present paper we solve completely this issue by providing the full range of modulation spaces in which the continuity of the cross-Wigner distribution $W(f,g)$ holds, as a function of $f,g$. The case of weighted modulation spaces is also considered. The consequences of our results are manifold: new bounds for the short-time Fourier transform and the ambiguity function, boundedness results for pseudodifferential (in particular, localization) operators and properties of the Cohen class.

description: A two-party quantum communication process with classical inputs and outcomes can be simulated by replacing the quantum channel with a classical one. The minimal amount of classical communication required to reproduce the statistics of the quantum process is called its communication complexity. In the case of many instances simulated in parallel, the minimal communication cost per instance is called the asymptotic communication complexity. Previously, we reduced the computation of the asymptotic communication complexity to a convex minimization problem. In most cases, the objective function does not have an explicit analytic form, as the function is defined as the maximum over an infinite set of convex functions. Therefore, the overall problem takes the form of a minimax problem and cannot directly be solved by standard optimization methods. In this paper, we introduce a simple algorithm to compute the asymptotic communication complexity. For some special cases with an analytic objective function one can employ available convex-optimization libraries. In the tested cases our method turned out to be notably faster. Finally, using our method we obtain 1.238 bits as a lower bound on the asymptotic communication complexity of a noiseless quantum channel with the capacity of 1 qubit. This improves the previous bound of 1.208 bits.

Number-resolved master equation approach to quantum measurement and quantum transport

description: In addition to the well-known Landauer-Buttiker scattering theory and the nonequilibrium Green's function technique for mesoscopic transports, an alternative (and very useful) scheme is quantum master equation approach. In this article, we review the particle-number (n)-resolved master equation (n-ME) approach and its systematic applications in quantum measurement and quantum transport problems. The n-ME contains rich dynamical information, allowing efficient study of topics such as shot noise and full counting statistics analysis. Moreover, we also review a newly developed master equation approach (and its n-resolved version) under self-consistent Born approximation. The application potential of this new approach is critically examined via its ability to recover the exact results for noninteracting systems under arbitrary voltage and in presence of strong quantum interference, and the challenging non-equilibrium Kondo effect.

description: Bio-inspired microfibers are applied to the suction wing surface of a small flying wing UA Vand their effect on aerodynamics and control surface performance is analyzed via wind tunnelexperim ents. The effects of fiber height, coverage area, flow regime and angle of attack are studied in the use of microfibers as a passive flow control method. Taller microfibers, when compared to a smooth wing, provide a drag reduction ofup to 24. 7% for Cr = 0.9 at higher Reynolds number, whereas shorter fibers perform better at lower Reynolds, with a 24. 2% drag reduction for the same lift coefficient. Control surface testing shows that when applying microfibers to the elevon and its upstream wing region, there is an improvement in pitch moment authority at higher angles of attack, with an increase in the pitch coefficient magnitude of up to 22. 4%. Microfiber coating films, while being incredibly practical for use, have the potential to improve the performance of small flying vehicles in certain conditions.
