description: CubeSats have revolutionized space experimentation by providing a small low-cost platform which has as a result enabled many who did not have access to space to now be able to easily perform experiments. However, one of the main shortcomings of CubeSats is the limited availability for on board sensing equipment and limited power available to perform certain types of experiments for long periods of time in orbit. This paper aims to design a modular re-entry capsule compatible with 2U+ CubeSats and using CFD and structural simulation methods to allow a safe re-entry from Low earth orbits.

description: We study the phase diagram and quantum critical region of one of the fundamental models for electronic correlations: the periodic Anderson model. Employing the recently developed dynamical vertex approximation, we find a phase transition between a zero-temperature antiferromagnetic insulator and a Kondo insulator. In the quantum critical region, we determine a critical exponent $γ\!=\!2$ for the antiferromagnetic susceptibility. At higher temperatures, we have free spins with $γ\!=\!1$ instead, whereas at lower temperatures, there is an even stronger increase and suppression of the susceptibility below and above the quantum critical point, respectively.

description: The phase diagram of two interacting planar arrays of directed lines in random media is obtained by a renormalization group analysis. The results are discussed in the contexts of the roughening of reconstructed crystal surfaces, and the pinning of flux line arrays in layered superconductors. Among the findings are a glassy flat phase with disordered domain structures, a novel second-order phase transition with continuously varying critical exponents, and the generic disappearance of the glassy ``super-rough'' phases found previously for a single array.

description: We investigate Yang-Mills theories with arbitrary gauge group on $R^3\times S^1$, whose symmetry is spontaneously broken by the Wilson loop. We show that instantons are made of fundamental magnetic monopoles, each of which has a corresponding root in the extended Dynkin diagram. The number of constituent magnetic monopoles for a single instanton is the dual Coxeter number of the gauge group, which also accounts for the number of instanton zero modes. In addition, we show that there exists a novel type of the $S^1$ coordinate dependent magnetic monopole solutions in $G_2,F_4,E_8$.

title: Sport for Change: A Theory and Practice Exploration
Creators: name: (:Unkn) Unknown
Publisher: name: George Mason University
Year: 2019

description: This research study is a qualitative exploration into the Theory of Change used in programs that engage sport as a vehicle to address conflict and create positive change. Primary data were gathered through open-ended interviews and observations with those who design and implement programs in order to understand how and why sport is used. An iterative research design generated key approaches that account for how micro-level efforts through sport is believed to foster macro-level positive change. This study describes, based on practitioner experience, how and why individuals are believed to overcome conflict through sport. In this manner, knowledge developed through practice will help to guide and potentially refocus knowledge developed through research in the sport for change and conflict resolution fields.

 Rhipicephalus supertritus has been confused with several species, such as Rhipicephalus bergeoni, Rhipicephalus compositus, Rhipicephalus longus and Rhipicephalus simus (Walker et al. 2000), and Guglielmone et al. (2020) treated redescriptions of Rhipicephalus supertritus as provisional. Among the several authors who have studied this tick, there are also stated differences in the geographic distribution of Rhipicephalus supertritus. The range of Rhipicephalus supertritus provided here accords with information published by Walker et al. (2000) and Kolonin (2009), but again, these data should be considered provisional.

description: A remarkable property of one-dimensional all-dielectric periodic structures has recently been reported, namely a one-dimensional lattice can totally reflect electromagnetic wave of any polarization at all angles within a prescribed frequency region. Unlike their metallic counterpart, such all-dielectric omnidirectional mirrors are nearly free of loss at optical frequencies. Here we discuss the physics, design criteria and applications of the thin-film all-dielectric omnidirectional mirror. The experimental demonstration of the mirror is presented at optical frequencies.

description: While quantum devices rely on interactions between constituent subsystems and with their environment to operate, native interactions alone often fail to deliver targeted performance. Coherent pulsed control provides the ability to tailor effective interactions, known as Hamiltonian engineering. We propose a Hamiltonian engineering method that maximizes desired interactions while mitigating deleterious ones by conducting a pulse sequence search using constrained optimization. The optimization formulation incorporates pulse sequence length and cardinality penalties consistent with linear or integer programming. We apply the general technique to magnetometry with solid state spin ensembles in which inhomogeneous interactions between sensing spins limit coherence. Defining figures of merit for broadband Ramsey magnetometry, we present novel pulse sequences which outperform known techniques for homonuclear spin decoupling in both spin-1/2 and spin-1 systems. When applied to nitrogen vacancy (NV) centers in diamond, this scheme partially preserves the Zeeman interaction while zeroing dipolar coupling between negatively charged NV$^{\text -}$ centers. Such a scheme is of interest for NV$^\text{-}$ magnetometers which have reached the NV$^\text{-}$-NV$^\text{-}$ coupling limit. We discuss experimental implementation in NV ensembles, as well as applicability of the current approach to more general spin bath decoupling and superconducting qubit control.

Assessment of Defects in the Quality of Rural Road Construction Projects: -A Case Study on Fiche-Gerbagurecha Flexible Pavement Road
Creators: name: Gemechu Mechessa
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2019
Subjects: Pavement defects, pavement evaluation, type and severity level of distress, PCI value, pavement maintenance

description: The main objective of this study is to assess defects in rural flexible pavement road projects in-order to identify appropriate type maintenance needs for the projects. Pavement maintenance work is performed from time to time to keep a pavement under normal conditions of as nearly as possible in its as-constructed condition. The selection of the right maintenance strategy at the right time is the most importance for an effective management of highway pavements. The appropriate maintenance strategy will be influenced by the type, severity, and extent of the pavement surface distresses and the structural and roughness condition of the pavement.
 The purpose of pavement maintenance is to correct deficiencies caused by distresses and to protect the pavement from further damage. A condition rating of the pavement will help determine what pavement maintenance technique is necessary. To identify maintenance type and rehabilitation need for the road, Pavement condition assessment is done by collecting condition survey and IRI as input data from Ethiopian Roads Authority. In order to obtain an overall assessment of pavement conditions for a road network, it is often necessary to combine individual distress data to form composite index called pavement condition index (PCI) summarizes the condition of each pavement segment. This pavement condition index is used to recommend the type of maintenance required for the road.
 The pavement evaluation results from the manual PCI survey revealed that all sections of road were fair condition. The pavement that has been studied would seem to require maintenance. Thick overlay (sometimes called surface treating) is needed in a whole pavement.

description: The effect of exogenous application of jasmonic acid (JA) on the concentration of main terpenes and density of glandular trichomes was investigated in the Mexican oregano, propagated from seeds from 3 localities. JA 1 mM was applied locally and to the whole plant. JA locally applied increased the number of trichomes, with a mean of 20 trichomes more with respect to the controls in plants from Tecomavaca and Zapotitlán Salinas, and significantly increased the thymol concentration by 185% systemically and 255% locally, compared to the control. JA applied to the whole plant decreased the number of trichomes and increased the concentration of caryophyllene from 0.79 to 1.7 mg g−1, and α-caryophyllene from 0.3 to 0.8 mg g−1 in plants from San Rafael with reference to water control. The results suggest a plasticity of morphologic and phytochemical responses, and a potential use of JA to improve phenolic monoterpenes and sesquiterpenes production.
Skyrmions from calorons

description: We derive a one-parameter family of gauged Skyrme models from Yang-Mills theory on $S^1\times\mathbb{R}^3$, in which skyrmions are well-approximated by calorons and monopoles. In particular we study the spherically symmetric solutions to the model with two distinct classes of boundary conditions, and compare them to calorons and monopoles. Calorons interpolate between instantons and monopoles in certain limits, and we observe similar behaviour in the constructed gauged Skyrme model in the weak and strong coupling limits. This comparison of calorons, monopoles, and skyrmions may be a way to further understand the apparent relationships between skyrmions and monopoles on $\mathbb{R}^3$.

description: The article [HPS] established a monotonicity inequality for the Helmholtz equation and presented applications to shape detection and local uniqueness in inverse boundary problems. The monotonicity inequality states that if two scattering coefficients satisfy $q_1 \leq q_2$, then the corresponding Neumann-to-Dirichlet operators satisfy $Λ(q_1) \leq Λ(q_2)$ up to a finite dimensional subspace. Here we improve the bounds for the dimension of this space. In particular, if $q_1$ and $q_2$ have the same number of positive Neumann eigenvalues, then the finite dimensional space is trivial.

description: 80. Rhipicephalus tetracornus Kitaoka & Suzuki, 1983.   Oriental: 1) Thailand (Kitaoka & Suzuki 1983).
 Rhipicephalus tetracornus was described from adults, nymphs and unconfirmed larvae. The adults and nymphs were subsequently lost, but the holotype (a nymph deposited in the National Science Museum, Tokyo) is available. Rhipicephalus tetracornus was not listed as valid by Keirans (1992), Horak et al. (2002) and Kolonin (2009), while Walker et al (2000) treated Rhipicephalus tetracornus as a species incertae sedis. By contrast, Rhipicephalus tetracornus was recognized as valid by Camicas et al. (1998), as well as Guglielmone et al. (2009, 2010 b, 2014, 2020) and Guglielmone & Nava (2014). Guglielmone et al. (2009) discussed the peculiar taxonomic situation of Rhipicephalus tetracornus, concluding that its description by Kitaoka and Suzuki (1983) is sound, a holotype is available for further analysis, and no studies have determined that this tick is a synonym of another species of Rhipicephalus. Therefore, no reasons yet exist to declare Rhipicephalus tetracornus invalid.

description: The phonon dispersion and the electron-phonon interaction for the $β$-Po and the bcc high pressure phases of tellurium are computed with density-functional perturbation theory. Our calculations reproduce and explain the experimentally observed pressure dependence of the superconducting critical temperature (T$_{\rm c}$) and confirm the connection between the jump in T$_{\rm c}$ and the structural phase transition. The phonon contribution to the free energy is shown to be responsible for the difference in the structural transition pressure observed in low and room temperature experiments.

 Adults of Rhipicephalus tricuspis have been confused with Rhipicephalus interventus and Rhipicephalus lunulatus (Walker et al. 1998, 1995, 2000), while Horak et al. (2018) added that morphological separation of the larvae and nymphs of Rhipicephalus follis, Rhipicephalus gertrudae, Rhipicephalus simus and Rhipicephalus tricuspis is extremely difficult. Records published prior to the study of Walker et al. (1988) are not included in this analysis.
 The presence of Rhipicephalus tricuspis in the Democratic Republic of the Congo is based on Walker et al. (2000), who included two localities in the western part of that country where this tick has been collected.
 ElGhali & Hassan (2012) continue to maintain that Rhipicephalus tricuspis is found in South Sudan, but there are no bona fide specimens of this tick from that country. Sylla et al. (2021) reported one collection of Rhipicephalus tricuspis from Senegal, but its presence there requires confirmation, and Senegal is provisionally excluded from the geographic distribution of Rhipicephalus tricuspis.

description: Folk medicine sometimes involves the use of salvia species for therapeutic purposes. Polyphenols with the highest amounts included rosmarinic acid (7.358mg/g), catechin (1.5 mg/g), vanillin (1.00 mg/g), chlorogenic acid (0.53 mg/g), quercetin (0.16 mg/g), and p-coumaric acid (0.015). Furthermore, the results showed that S. multicaulis has a high content of total phenol (4.39 mg/g) and DPPH activity (8.44 mg/g). Salvia multicaulis could be potentially used as a medicinal plant because of its antioxidant activity and polyphenol content.

description: We study long-term growth-optimal strategies on a simple market with linear proportional transaction costs. We show that several problems of this sort can be solved in closed form, and explicit the non-analytic dependance of optimal strategies and expected frictional losses of the friction parameter. We present one derivation in terms of invariant measures of drift-diffusion processes (Fokker- Planck approach), and one derivation using the Hamilton-Jacobi-Bellman equation of optimal control theory. We also show that a significant part of the results can be derived without computation by a kind of dimensional analysis. We comment on the extension of the method to other sources of uncertainty, and discuss what conclusions can be drawn about the growth-optimal criterion as such.

description: We classify the sensitivities of the future high energy hadron and electron colliders, such as the LHC and the future Linear Colliders, to probing all the next-to-leading order (NLO) bosonic operators for studying the electroweak symmetry breaking (EWSB) mechanism. We first develop a power counting rule (a generalization of Weinberg's counting method for the nonlinear sigma model) for the electroweak theories formulated by the chiral Lagrangian. Then, we formulate the Longitudinal-Goldstone Boson Equivalence Theorem as a physical criterion to discriminate the scattering processes that are not sensitive to the EWSB sector. The "complementarity" of different scattering processes via different colliders for a complete probe of all these NLO effective operators is demonstrated.

description: We present a systematic study of the effect of crack blunting on subsequent crack propagation and dislocation emission. We show that the stress intensity factor required to propagate the crack is increased as the crack is blunted by up to thirteen atomic layers, but only by a relatively modest amount for a crack with a sharp 60$^\circ$ corner. The effect of the blunting is far less than would be expected from a smoothly blunted crack; the sharp corners preserve the stress concentration, reducing the effect of the blunting. However, for some material parameters blunting changes the preferred deformation mode from brittle cleavage to dislocation emission. In such materials, the absorption of preexisting dislocations by the crack tip can cause the crack tip to be locally arrested, causing a significant increase in the microscopic toughness of the crack tip. Continuum plasticity models have shown that even a moderate increase in the microscopic toughness can lead to an increase in the macroscopic fracture toughness of the material by several orders of magnitude. We thus propose an atomic-scale mechanism at the crack tip, that ultimately may lead to a high fracture toughness in some materials where a sharp crack would seem to be able to propagate in a brittle manner. Results for blunt cracks loaded in mode II are also presented.

They are the first known hollow lattice polytopes of width larger than dimension. We also construct a hollow (non-lattice) tetrahedron of width $2+\sqrt2$ and conjecture that this is the maximum width among $3$-dimensional hollow convex bodies. We show that the maximum lattice width grows (at least) additively with $d$. In particular, the constructions above imply the existence of hollow lattice polytopes (resp. hollow simplices) of arbitrarily large dimension $d$ and width $\simeq 1.14 d$ (resp.$~\simeq 1.01 d$).

description: Hydro-distilled essential oils, from fresh rhizomes and leaves of Curcuma mutabilis Škorničk., M.Sabu & Prasanthk., characterized by GC–MS revealed the presence of thirty three and twenty three compounds therein respectively. Whilst estrone methyl ether (3-Methoxyestra-1,3,5(10)-trien-17-one) was the major component in rhizome oil (47.35%), sesquiterpene hydrocarbons predominated as the major group (63.92%) in leaf oil with a higher preponderance of β-caryophyllene (25.48%), β-farnesene (19.47%) and α-humulene (11.01%). Weak antioxidant activities observed in these oils determined by DPPH and ABTS methods were apparently influenced both by the oil composition and the assay conditions. Rhizome oil showed higher antiproliferative activity than leaf oil against leukemic K562 (IC50-6.8µg/mL) and colorectal HCT116 (IC50-8.5µg/mL) cancer cell lines. This first report reveals composition and biological activities of essential oils from C. mutabilis.

Type locality. Sow and Pigs Reef, Port Jackson, New South Wales, Australia (33°30′S 151°16′E).
Material examined. New South Wales: male, dissected, 8.0 mm, 4 slides, east of Bermagui, (36°26′S 150°14′6″E), AM P. 92234, 120m, benthic sled, 5 September 1994, coll. P. Berents (SS05/94/155).
Remarks. In the material from Bermagui, New South Wales (AM P.92234), the telson is longer than broad unlike the specimen figured by Lowry & Springthorpe (2005) which is broader than long. The antennae 1 article is also variable in the number of robust setae along the posterior margin, the right peduncle has three evenly spaced setae while the left has only two distal robust setae, which differs from the Lowry & Springthorpe (2005) material which has one proximal and one distal robust setae. These differences are considered intraspecific variation.
Distribution. New South Wales: Port Jackson; Bermagui (Haswell 1879b; Lowry & Springthorpe 2005; current study).

description: We present a detailed analysis of hole dynamics in noble metals (Cu and Au), by means of first-principles many-body calculations. While holes in a free-electron gas are known to live shorter than electrons with the same excitation energy, our results indicate that d-holes in noble metals exhibit longer inelastic lifetimes than excited sp-electrons, in agreement with experiment. The density of states available for d-hole decay is larger than that for the decay of excited electrons; however, the small overlap between d- and sp-states below the Fermi level increases the d-hole lifetime. The impact of d-hole dynamics on electron-hole correlation effects, which are of relevance in the analysis of time-resolved two-photon photoemission experiments, is also addressed.

Time evolution of entropy associated with diffusivity fluctuations: Diffusing diffusivity approach

description: It has experimentally been found by Lampo et al. [Biophys. J. 112, 532 (2017)] that, for two different types of cell, the distribution of the diffusivities of RNA-protein particles over cytoplasm obeys an exponential law. Then, an interesting issue has been pointed out: this exponential distribution is the maximal entropy distribution. Here, time evolution of entropy associated with local fluctuations of the diffusivity is studied. The entropy rate under the diffusing diffusivity equation, which admits the exponential fluctuation as its stationary solution, is shown to be positive. The present result is expected to be useful for studying the dynamics of diffusivity fluctuations. Furthermore, the distribution of time being required for characteristic displacement of the RNA-protein particle is found to decay as a power law. A comment is also made on a formal analogy with the thermodynamic relation concerning temperature.

description: It has recently been suggested that an exactly solvable problem characterized by a new quantum number may underlie the electronic shell structure observed in the mass spectra of medium-sized sodium clusters. We investigate whether the conjectured quantum number 3n+l bears a similarity to the quantum numbers n+l and 2n+l, which characterize the hydrogen problem and the isotropic harmonic oscillator in three dimensions.

Enhancement of axion decay constants in type IIA theory?

description: We investigate the possibility of enhancement of effective axion decay constant in well controlled constructions in string theory. To this end, we study the dynamics of axions arising in the compactifications of type IIA string theory on Calabi-Yau orientifolds with background fluxes (with non-perturbative effects included to ensure stabilization of all moduli). In this setup, we attempt to obtain large effective axion decay constant in two different ways: by searching for a direction in field space in which the potential is sufficiently flat and by arriving at a very explicit stringy embedding of the Kim-Nilles-Peloso (KNP) alignment mechanism. We do not find super-Planckian effective decay constants by either of the approaches. Furthermore, we find that the alignment angle of KNP mechanism can not be made arbitrarily small by adjusting the fluxes.

Vacuum oscillations of solar neutrinos: correlation between spectrum distortion and seasonal variations

description: Long length vacuum oscillations solution of the solar neutrino problem is discussed. We show that there is a strict correlation between a distortion of the neutrino energy spectrum and an amplitude of seasonal variations of the neutrino flux. The slope parameter which characterizes a distortion of the recoil electron energy spectrum in the Super-Kamiokande experiment and the seasonal asymmetry of the signal have been calculated in a wide range of oscillation parameters. The correlation of the slope and asymmetry gives crucial criteria for identification or exclusion of this solution. For the positive slope indicated by preliminary Super-Kamiokande data we predict (40 - 60) % enhancement of the seasonal variations.

description: We use the planetary ephemeris INPOP17b to constrain the mass of the graviton in the Newtonian limit. We also give an interpretation of this result for a specific case of fifth force framework. We find that the residuals for the Cassini spacecraft significantly (90\% C.L.) degrade for Compton wavelengths of the graviton smaller than $1.83\times 10^{13}$ km, corresponding to a graviton mass bigger than $6.76\times 10^{-23} eV/c^2$. This limit is comparable in magnitude to the one obtained by the LIGO-Virgo collaboration in the radiative regime. We also use this specific example to illustrate why constraints on alternative theories of gravity obtained from postfit residuals are generically overestimated.

description: Objectives: Hepatorenal Syndrome (HRS) is characterized by renal failure in patients with advanced chronic liver disease (CLD) and is the leading cause of hospitalizations in CLD. This study examines the clinical and economic burden, outcomes, and unmet need of HRS treatment in US hospitals. Method: A retrospective cohort study was conducted based on a large electronic health records database (Cerner HealthFacts) with records for hospitalized HRS patients from January 2009–June 2015. Demographics, clinical characteristics, treatment patterns, and economic outcomes were analyzed. Prognostic indicators of cirrhosis, kidney injury, end-stage liver disease, and acute-on-chronic liver failure were used to determine mortality risk. Results: A total of 2,542 patients hospitalized with HRS were identified (average age = 57.9 years, 61.8% males, 74.2% Caucasian), with an average total hospital charge of $91,504 per patient and a mean length of stay (LOS) of 30.5 days. The mortality rate was 36.9% with 8.9% of patients discharged to hospice. Of all patients, 1,660 patients had acute kidney injury, 859 with Stage 3 disease, and 26.7% had dialysis. The 30-day readmission rate was 33.1%, 41% of which were unplanned. Nearly one-third of study patients had commercial insurance (30.2%), followed by Medicare (29.9%); hospital charges varied by LOS, receipt of dialysis, and discharge status. Regression analysis demonstrated that HRS costs are associated with LOS, dialysis, and hospital mortality. Conclusion: HRS is associated with poor outcomes and high hospital costs. Analysis of HRS cost drivers demonstrated an unmet need for additional treatment options to improve outcomes in this patient population.

description: The asymptotic high momentum behaviour of quantum field theories with cubic interactions is investigated using renormalization group techniques in the asymmetric limit x << 1. Particular emphasis is paid to theories with interactions involving more than one field where it is found that a matrix renormalization is necessary. Asymptotic scaling forms, in agreement with Regge theory, are derived for the elastic two-particle scattering amplitude and verified in one-loop renormalization group improved perturbation theory, corresponding to the summation of leading logs to all orders. We give explicit forms for the Regge trajectories of different scalar theories in this approximation and determine the signatures.

description: In the modern warfare, missiles are required to attack maneuvering targets. However, saturation is a potential problem for actuators of guidance systems to be considered. This paper concentrates on the problem of designing a three-dimensional nonlinear guidance law accounting for saturation nonlinearity. To solve the physical constraints of missile actuators, an anti-disturbance and anti-saturation terminal sliding mode guidance law is provided based on radial basis functions neural networks. Numerical simulations are introduced to demonstrate the effectiveness and superiority of the designed composite guidance law in theory.
