description: Part of a collection of correspondence between Sir Herbert Read and Alfred Richard Orage. Orage is most well-known for editing the magazine “The New Age”. These letters, spanning 1921 and 1922, primarily discuss Read’s work as a Readers and Writers columnist for the magazine in that time. In these letters Orage also frequently mentions P. D. Ouspensky, who studied under philosopher G. I. Gurdjieff. In 1922 Orage sold “The New Age” and moved to Paris in order to also study under Gurdjieff. In this postcard, Orage gives some advice on the Readers and Writers column.

description: The propagation of cosmic rays in turbulent magnetic fields is a diffusive process driven by the scattering of the charged particles by random magnetic fluctuations. Such fields are usually highly intermittent, consisting of intense magnetic filaments and ribbons surrounded by weaker, unstructured fluctuations. Studies of cosmic ray propagation have largely overlooked intermittency, instead relying on Gaussian random magnetic fields. Using test particle simulations, we investigate cosmic ray diffusivity in intermittent, dynamo-generated magnetic fields. The results are compared with those obtained from non-intermittent magnetic fields having identical power spectra. The presence of magnetic intermittency significantly enhances cosmic ray diffusion over a wide range of particle energies. We demonstrate that the results can be interpreted in terms of a correlated random walk.

description: Obesity is a significant public health issue as it seems to be the cause for high blood pressure, diabetes and other health problems. The human body cannot function efficiently if it has high body mass index score. According to the National Health and Morbidity Survey (NHMS), people with BMI score of ≥ 25 are being categorized as obese. One way to control obesity is to rely on the help of technology such as mobile health applications. In literature, there is a lack in research addressing obese people’s intention of using mobile health applications. Recognising the critical role of their behavioural intention to use mobile health applications, this research investigates the factors affecting behavioural intention to use mobile health applications. Adapting Consumer Acceptance Technology (CAT) model by Kulviwat et al. (2007) and Health Belief Model (HBM) developed by Glanz et al. (2008), this research examines factors of perceived cognition, perceived affection, perceived threat, compatibility, accessibility and attitude towards behavioural intention to use mobile health apps. To test the proposed framework, data were collected using quota sampling, while questionnaires were distributed to 500 obese people in the top 5 percent in the states with the obesity population in Malaysia, namely Malacca, Federal Territory of Putrajaya, Negeri Sembilan, Kedah and Perlis. Data collected were analysed using Partial Least Square (PLS) software. The results show that relationship between perceived cognition and perceived affection towards behavioural intention to use is partially significant, while significant relationship has been found between perceived threat, compatibility and accessibility and behavioural intention to use. Besides, perceived cognition and perceived affection partially support relationship on attitude. On the other hand perceived threat, compatibility and accessibility fully support relationship on attitude. Finally, the results demonstrate attitude partially mediates the relationship between perceived cognition and perceived affection, while attitude fully mediates the effect of perceived threat, compatibility, accessibility on behavioural intention to use. Findings provided empirical evidence on the collective effect of behavioural intention to use mobile health applications as well as independent effect of perceived cognition, perceived affection, perceived threat, compatibility and accessibility. Besides, findings suggested to encourage individual to use mobile health applications, while related stakeholders should continually improve user perception on health applications.

description: $^{133}\text{Ba}^+$ has been identified as an attractive ion for quantum information processing due to the unique combination of its spin-1/2 nucleus and visible wavelength electronic transitions. Using a microgram source of radioactive material, we trap and laser-cool the synthetic $A$ = 133 radioisotope of barium II in a radio-frequency ion trap. Using the same, single trapped atom, we measure the isotope shifts and hyperfine structure of the $6^2 \text{P}_{1/2}$ $\leftrightarrow$ $6^2 \text{S}_{1/2}$ and $6^2 \text{P}_{1/2}$ $\leftrightarrow$ $5^2 \text{D}_{3/2}$ electronic transitions that are needed for laser cooling, state preparation, and state detection of the clock-state hyperfine and optical qubits. We also report the $6^2 \text{P}_{1/2}$ $\leftrightarrow$ $5^2 \text{D}_{3/2}$ electronic transition isotope shift for the rare $A$ = 130 and 132 barium nuclides, completing the spectroscopic characterization necessary for laser cooling all long-lived barium II isotopes.

description: We prove an analogue of the Lewy extension theorem for a real dimension $2n$ smooth submanifold $M \subset {\mathbb C}^{n}\times {\mathbb R}$, $n \geq 2$. A theorem of Hill and Taiani implies that if $M$ is CR and the Levi-form has a positive eigenvalue restricted to the leaves of ${\mathbb C}^n \times {\mathbb R}$, then every smooth CR function $f$ extends smoothly as a CR function to one side of $M$. If the Levi-form has eigenvalues of both signs, then $f$ extends to a neighborhood of $M$. Our main result concerns CR singular manifolds with a nondegenerate quadratic part $Q$. A smooth CR $f$ extends to one side if the Hermitian part of $Q$ has at least two positive eigenvalues, and $f$ extends to the other side if the form has at least two negative eigenvalues. We provide examples to show that at least two nonzero eigenvalues in the direction of the extension are needed.

description: El trabajo presenta dos canciones tojolabales, mayas de los Altos de Chiapas, México. Han sido compuestas por varios indígenas anónimos en los últimos años. Las canciones son testimonio de como los tojolabales ven la sociedad dominante en la cual viven. La primera canción habla de la estancia de un indígena en un hospital urbano. La segunda enfoca el problema de la tenencia de la tierra. A pesar de programas de salud y de reforma agraria, los indígenas ven que hasta la fecha estos programas no les han servido, ni les han abierto el camino hacia la convivencia pacífica que buscan, sino que los impulsan a luchar.

Effects of Nitrogen Inhibitors and Slow Nitrogen Releasing Fertilizers on Crop Yield, Nitrogen Use Efficiency and Mitigation of Nitrous Oxide (N2O) Emission

description: Improving the production and productivity of crops through appropriate nutrient management including nitrogen fertilizer is one of the most important means to satisfy the food demand of the ever increasing world’s population. Consequently, intensive use of nitrogen fertilizers increase cost of production and cause environmental pollution through different forms of nitrogen losses such as nitrate (NO-3) leaching, ammonia (NH3) volatilization and nitrous oxide (N2O) emission. The main aim of this paper is, therefore, to review the effects of nitrogen inhibitors and slow nitrogen releasing fertilizers on crop yield, nitrogen use efficiency and mitigation of N2O emission. Various research results showed that application of nitrification inhibitors (DCD, DMPP, thiosulfate, neem, and N-serve), urease inhibitors such as agrotain, PPD, NBPT and hydroquinone, and slow nitrogen releasing fertilizers like polymer and sulfur coated urea substantially improved nitrogen use efficiency and yield of crops as well as significantly mitigating GHG (N2O) emission. Therefore, application of such technologies has great contribution to reduce environmental pollution caused by intensive utilization of nitrogen fertilizers while increasing crop yields.

description: By a result of Biswas and Dos Santos, on a smooth and projective variety over an algebraically closed field, a vector bundle trivialized by a proper and surjective map is essentially finite, that is it corresponds to a representation of the Nori fundamental group scheme. In this paper we obtain similar results for non-proper non-smooth algebraic stacks over arbitrary fields of characteristic $p>0$. As by-product we have the following partial generalization of the Biswas-Dos Santos' result in positive characteristic: on a pseudo-proper and inflexible stack of finite type over $k$ a vector bundle which is trivialized by a proper and flat map is essentially finite.

description: Se examinan a vista v a los rayos X seis figuritas piernabiertas estilo Lagarto, halladas en dos de los cuatro cementerios Chiriquí Clásico del Soncho (excavaciones en la región de San Vito de Java, Costa Rica, de Minelli y la autora, 1959-1962). Se enfocan en la estratigrafía local del Chiriquí Clásico, en la arqueología cultural de las tumbas que las encerraron, en las relaciones de los cronistas y en la etnografía de la región. Se reconstruyen las técnicas de manufactura de las figuritas y el fin para el cual se manufacturaron que es el de exhibirlas, sea sentadas sobre un plano, sea insertadas en una especie de tridente, sea colgadas de una cuerdecilla, siempre bien ornadas con pendientes. Se concluye que estas figuritas de mujer con cara ornitomorfa, semejante a la del buho, son efigies que se exhibían tal vez en las ceremonias públicas de la fecundidad y, en casos particulares, relacionados también con la fecundidad, como los de alumbramientos difíciles.

description: The Generalist Repository Ecosystem Initiative (GREI) hosted a 2-day virtual workshop presented by the seven participating generalist repositories on January 24 & 25, 2023. The NIH Office of Data Science Strategy sponsored workshop focused on GREI's vision of developing collaborative approaches for data management and sharing through inclusion of the generalist repositories in the NIH data ecosystem, and better enabling search and discovery of NIH-funded data in the generalist repositories. The workshop featured keynote speakers and panel discussions with leaders in open data from the research community, NIH, and data community organizations. Interactive training sessions were led by GREI repositories, presenting use-case-specific guidance on sharing and discovering data in generalist repositories. Presenters also gathered community feedback to inform future GREI work and to enhance support for NIH data sharing with common functionality, interoperability, and “coopetition” among generalist repositories.

description: We study the critical behavior of the 2D $N$-color Ashkin-Teller model in the presence of random bond disorder whose correlations decays with the distance $r$ as a power-law $r^{-a}$. We consider the case when the spins of different colors sitting at the same site are coupled by the same bond and map this problem onto the 2D system of $N/2$ flavors of interacting Dirac fermions in the presence of correlated disorder. Using renormalization group we show that for $N=2$, a "weakly universal" scaling behavior at the continuous transition becomes universal with new critical exponents. For $N>2$, the first-order phase transition is rounded by the correlated disorder and turns into a continuous one.

description: Datos del siglo XVII son empleados para un examen de gentilicios y afinidades de los grupos aborígenes del noroeste colombiano durante la Conquista española. Este reconocimiento retrospectivo apoya la hipótesis, propuesta por Lehmann y otros, sobre una separación de la población cueva del istmo panameño con ramos aislados hacia el sur. Esta separación, sin embargo, no ha sido instigada por una invasión de los choco cuyas migraciones por el litoral pacifico son mas recientes, sino por un avance de una gente poderosa del este con rasgos culturales que la distinguen tanto de los cueva como de los choco. A causa de un dramático diezmo de la población, los últimos sobrevivientes - los gorgona - son transportados a Panamá por los españoles a fines del siglo XVII.

description: Molecular dynamics (MD) simulations are used to investigate $^1$H nuclear magnetic resonance (NMR) relaxation and diffusion of bulk $n$-C$_5$H$_{12}$ to $n$-C$_{17}$H$_{36}$ hydrocarbons and bulk water. The MD simulations of the $^1$H NMR relaxation times $T_{1,2}$ in the fast motion regime where $T_1 = T_2$ agree with measured (de-oxygenated) $T_2$ data at ambient conditions, without any adjustable parameters in the interpretation of the simulation data. Likewise, the translational diffusion $D_T$ coefficients calculated using simulation configurations are well-correlated with measured diffusion data at ambient conditions. The agreement between the predicted and experimentally measured NMR relaxation times and diffusion coefficient also validate the forcefields used in the simulation. The molecular simulations naturally separate intramolecular from intermolecular dipole-dipole interactions helping bring new insight into the two NMR relaxation mechanisms as a function of molecular chain-length (i.e. carbon number). Comparison of the MD simulation results of the two relaxation mechanisms with traditional hard-sphere models used in interpreting NMR data reveals important limitations in the latter. With increasing chain length, there is substantial deviation in the molecular size inferred on the basis of the radius of gyration from simulation and the fitted hard-sphere radii required to rationalize the relaxation times. This deviation is characteristic of the local nature of the NMR measurement, one that is well-captured by molecular simulations.

description: In this study we synthesize the results of four previous studies on the global energetics of solar flares and associated coronal mass ejections (CMEs), which include magnetic, thermal, nonthermal, and CME energies in 399 solar M and X-class flare events observed during the first 3.5 years of the Solar Dynamics Observatory (SDO) mission. Our findings are: (1) The sum of the mean nonthermal energy of flare-accelerated particles ($E_{\mathrm{nt}}$), the energy of direct heating ($E_{\mathrm{dir}}$), and the energy in coronal mass ejections ($E_{\mathrm{CME}}$), which are the primary energy dissipation processes in a flare, is found to have a ratio of $(E_{\mathrm{nt}}+E_{\mathrm{dir}}+ E_{\mathrm{CME}})/E_{\mathrm{mag}} = 0.87 \pm 0.18$, compared with the dissipated magnetic free energy $E_{\mathrm{mag}}$, which confirms energy closure within the measurement uncertainties and corroborates the magnetic origin of flares and CMEs; (2) The energy partition of the dissipated magnetic free energy is: $0.51\pm0.17$ in nonthermal energy of $\ge 6$ keV electrons, $0.17\pm0.17$ in nonthermal $\ge 1$ MeV ions, $0.07\pm0.14$ in CMEs, and $0.07\pm0.17$ in direct heating; (3) The thermal energy is almost always less than the nonthermal energy, which is consistent with the thick-target model; (4) The bolometric luminosity in white-light flares is comparable with the thermal energy in soft X-rays (SXR); (5) Solar Energetic Particle (SEP) events carry a fraction $\approx 0.03$ of the CME energy, which is consistent with CME-driven shock acceleration; and (6) The warm-target model predicts a lower limit of the low-energy cutoff at $e_c \approx 6$ keV, based on the mean differential emission measure (DEM) peak temperature of $T_e=8.6$ MK during flares. This work represents the first statistical study that establishes energy closure in solar flare/CME events.

Dielectric permeability tensor and linear waves in spin-1/2 quantum kinetics with non-trivial equilibrium spin-distribution functions

description: A consideration of waves propagating parallel to the external magnetic field is presented. The dielectric permeability tensor is derived from quantum kinetic equations with non-trivial equilibrium spin-distribution functions (NTESDF) in the linear approximation on amplitude of wave perturbations. In general case, x- and y-projections of the SDF are nonzero which is called the non-trivial regime. Corresponding equilibrium solution is found. Contribution of the NTESDF appears in the dielectric permeability tensor in the additive form. It is explicitly found here. Corresponding modification in the dispersion equation for the transverse waves is derived. Contribution of NTESDF in the spectrum of transverse waves is calculated numerically. It is found that the term caused by the NTESDF can be comparable with the classic terms for the relatively small wave vectors and frequencies above the cyclotron frequency. In majority of regimes, the extra spin caused term dominates over the spin term found earlier, except the small frequency regime, where their contributions in the whistler spectrum are comparable. A decrease of the left-hand circularly polarized wave frequency, an increase of the high-frequency right-hand circularly polarized wave frequency, and a decrease of frequency changing by an increase of frequency at the growth of the wave vector for the whistler are found. A dramatic decrease of the spin wave frequency resulting in several times larger group velocity of the spin wave is found either. Found dispersion equations are used for obtaining of an effective quantum hydrodynamics reproducing these results. This generalization requires the introduction of corresponding equation of state for the thermal part of the spin current in the spin evolution equation.

Tres relatos obtenidos al respecto, que provienen de la región de Otavalo/provincia de Imbabura, de la de Riobamba y de la Laguna de Colta/provincial de Chimborazo, se reproducen en su versión original en quechua con la correspondiente traducción al castellano. Muchos de los juegos descritos se conocen en Europa como juegos de niños; dos relatos facilitan detalles en relación con el juego del huairu cuya tradición se remonta a tiempos prehispánicos. La serie de distracciones a las que recurren los asistentes a un velorio a fin de vencer el sueño incluye también algunas inventadas a raíz de la realidad sociocultural. A más de comprobar la sobrevivencia de los juegos funerarios los datos presentados en este aporte revelan que sigue en uso la costumbre de enterrar ofrendas junto con el cadáver.

Les offrandes d'enfants. Essai d'interprétation d'une scène de l'iconographie mochica
Creators: name: Hocquenghem, Anne Marie
Publisher: name: INDIANA
Year: 1980

description: La autora trata de interpretar las representaciones mochicas ( costa norte del Perú entre -200 y 700) utilizando las informaciones de los etnohistoriadores y de los etnólogos. Escenas de ofrendas de niños, de vestidos, de pequeños objetos y de coca en relación con el consume de estas hojas debajo de un arco bicéfalo podrían ilustrar un rito de entronización celebrado en los momentos de los solsticios, al comienzo de las estaciones húmedas y secas, cuando se dan poderes a los jefes y cuando los jóvenes son reconocidos como adultos.

El estilo Jequetepeque I. Desarrollo y comparaciones con estilos contemporáneos en la costa norte del Perú
Creators: name: Hecker, Wolfgang

Publisher: name: INDIANA
Year: 1980

description: En las ilustraciones adjuntas a esta disertación se ven reproducidos fragmentos de vasos de uso diario, que documentan en cerámica el nacimiento del estilo Jequetepeque I a partir del estilo Chavfn tardío. Se trata de un desarrollo propio del valle de Jequetepeque que muestra semejanzas con estilos ya conocidos, provenientes de valles más al sur y al norte, como por ejemplo Viru y Vicús. Este desarrollo, considerando la casi total falta de representaciones del dios felino, indica cambios en las ideas religiosas, documentando, además, analogías estilísticas y contactos con regiones alejadas y señalando, en consecuencia, la existencia de una cultura sobreregional.

description: We have studied the ground states of two dimensional lattice model of Coulomb Glass via Monte Carlo annealing. Our results show a possibility of existence of a critical disorder (Wc) below which the system is in the charge ordered phase and above it the system is in the disordered phase. We have used finite size scaling to calculate Wc = 0.2413, the critical exponent of magnetization β = 0 indicating discontinuity in magnetization and the critical exponent of correlation length ν = 1.0. The distribution of staggered magnetization for different disorder strengths shows a three peak structure. We thus predict that two dimensional Coulomb Glass shows a first order transition at T=0.

description: The NASA K2 mission uses photometry to find planets transiting stars of various types. M dwarfs are of high interest since they host more short period planets than any other type of main sequence stars and transiting planets around M dwarfs have deeper transits compared to other main sequence stars. In this paper, we present stellar parameters from K and M dwarfs hosting transiting planet candidates discovered by our team. Using the SOFI spectrograph on the European Southern Observatory's New Technology Telescope, we obtained R ~ 1000 J-, H-, and K-band (0.95 - 2.52 microns) spectra of 34 late-type K2 planet and candidate planet host systems and 12 bright K4-M5 dwarfs with interferometrically measured radii and effective temperatures. Out of our 34 late-type K2 targets, we identify 27 of these stars as M dwarfs. We measure equivalent widths of spectral features, derive calibration relations using stars with interferometric measurements, and estimate stellar radii, effective temperatures, masses, and luminosities for the K2 planet hosts. Our calibrations provide radii and temperatures with median uncertainties of 0.059 R_sun (16.09%) and 160 K (4.33%), respectively. We then reassess the radii and equilibrium temperatures of known and candidate planets based on our spectroscopically derived stellar parameters. Since a planet's radius and equilibrium temperature depends on the parameters of its host star, our study provides more precise planetary parameters for planets and candidates orbiting late-type stars observed with K2. We find a median planet radius and an equilibrium temperature of approximately 3R_earth and 500 K, with several systems (K2-18b and K2-72e) receiving near-Earth like levels of incident irradiation.

Informe sobre los hallazgos en Sechín. Monumento arqueológico en la costa norte del Perú
Creators: name: Samaniego, Lorenzo
Publisher: name: INDIANA
Year: 1980

description: Sechín desde hace pocos años presenta nuevas evidencias sobre el desarrollo de la arquitectura y de la escultura en las épocas más tempranas del Antiguo Perú. Descubierto por el Dr. Julio C. Tello en 1937, recién se propiciaron nuevas investigaciones en él durante los bienios1971-1972 y 1973-1974, con el aporte del Gobierno Peruano a través de la CRYRZA, ORDEZA, encargándose la tarea al Instituto Nacional de Cultura y, al autor desde el inicio los trabajos de campo con resultados satisfactorios. En el primer bienio dirigió la labor el Dr. Arturo Jiménez Borja, a quien debe mucho la Arqueología Peruana. Presento una descripción muy apretada de la significación de Sechín, reseño noticias de documentos de los siglos XVI, XVII, XVIII y XIX, buscando la explicación al nombre de Sechín; también las investigaciones de Tello y de los demás investigadores que nos antecedieron; finalmente, tratamos la arquitectura y la escultura del monumento, quedando pendiente muchas noticias, esperando puedan aparecer en un próximo artículo.

description: Graphene is known to possess strong optical nonlinearity. Its nonlinear response can be further enhanced by graphene plasmons. Here, we report a novel nonlinear electro-absorption effect observed in nanostructured graphene due to excitation of graphene plasmons. We experimentally detect and theoretically explain enhanced nonlinear mixing of near-infrared and mid-infrared light in arrays of graphene nanoribbons. Strong compression of light by graphene plasmons implies that the effect is non-local in nature and orders of magnitude larger than the conventional local graphene nonlinearity. The effect can be used in variety of applications including nonlinear light modulators, light multiplexors, light logic, and sensing devices.

Die Pyramiden von Túcume (Departamento de Lambayeque, Peru)
Creators: name: Trimborn, Hermann
Publisher: name: INDIANA
Year: 1980

description: El artículo refiere resultados científicos realizados in situ entre los años 1967 a 1975. En conexión con los trabajos anteriores de Wendell C . Bennett, A. L. Kroeber, R. Schaedel y P. Kosok, el punto esencial de las investigaciones del autor fueron problemas de la arquitectura y aclaraciones acerca de la construcción. En este orden de ideas fueron ejecutadas las primeras mediciones de la altura de las pirámides y, ante todo, se obtuvieron las primeras pruebas radiométricas (C14) cuyas fechas abarcan un período desde 1010 hasta 1290 de nuestra era;  corresponden, con esto, inequívocamente a la época de Naymlap y sus herederos, o sea, a la primera mitad del así llamado "Intermedio Tardío".

Acó (Perú) pueblo de alfareros
Creators: name: Sabogal Wiesse, José Rodolfo
Publisher: name: INDIANA
Year: 1980

description: El pueblo indígena de Acó se encuentra ubicado en la sierra central del Perú, a 3380 mts. s/n/m, en el confín occidental del productivo valle del Mantaro. Esta comunidad agraria constituye un pueblo tradicional de campesinos-alfareros en una región en la cual cada pueblo tiene asignado una función y practica una artesanía diferente. Acó está situado en el límite ecológico de la zona "Quechua" templada, hasta donde crece el maíz, con aquella "Suni" más fría y en donde la agricultura tiene resultados aleatorios. Es por eso que Acó representa una suerte de centro de acopio a la vez que de aprovisionamiento del maíz, el grano más apreciado en los Andes. En este cuadro la cerámica contribuye como elemento de trueque, y hoy como fuente de ingresos en efectivo. Esta importancia del trueque en Acó es recalcada por los relatos de aquenses, cuando niños, en que recibían productos de las zonas altas vecinas, y se aprovisionaban de maíz. La cerámica encaja - así - de manera adecuada dentro de su economía local y doméstica, a la vez que les proporciona un elemento de intercambio utilísimo. Pues hay que tener en cuenta que los labrantíos de los cuales disponen son insuficientes y la producción agrícola aleatoria debido a las condiciones climáticas. La fabricación de cerámica coincide con el ciclo económico y se encaja de acuerdo con las estaciones y la vegetación así como las fiestas patronales del valle y las actividades familiares. El asentamiento humano es nuclear, sumando 5200 habitantes en 1972.Existen 100 hornos de cerámica, artesanía que conocen todos los aquenses. Tanto como la agricultura. Cada barrio del pueblo se encuentra especializado en la fabricación de determinada pieza cerámica. Este trabajo se realiza sobre todo durante la época seca de junio a noviembre, existiendo prevenciones sobre la practica de la cerámica durante la época lluviosa. Se describe a continuación la técnica cerámica utilizada y se mencionan todos los tipos de piezas fabricadas, así como sus precios en 1976. El mercadeo de los cerámicos lo realizan mayormente intermediarios del pueblo, tal como en todos los centros productores de artesanías de la sierra central del Perú. Dichos intermediarios son generalmente parientes de los alfareros, y el costo de su servicio es elevado. La cerámica es conducida en automotores a las ferias regionales indígenas del valle del Mantaro, adonde son vendidas en efectivo, teniendo gran demanda. Otros tipos de cerámica, especiales, como máscaras y juguetes, son fabricados para fechas fastas en el valle. El artículo termina haciendo recomendaciones de mayores estudios y de procurar un mejor entorno para la práctica de la cerámica.

description: Fast collisionless shocks in cosmic plasmas convert their kinetic energy flow into the hot downstream thermal plasma with a substantial fraction of energy going into a broad spectrum of superthermal charged particles and magnetic fluctuations. The superthermal particles can penetrate into the shock upstream region producing an extended shock precursor. The cold upstream plasma flow is decelerated by the force provided by the superthermal particle pressure gradient. In high Mach number collisionless shocks, efficient particle acceleration is likely coupled with turbulent magnetic field amplification (MFA) generated by the anisotropic distribution of accelerated particles. This anisotropy is determined by the fast particle transport making the problem strongly nonlinear and multi-scale. Here, we present a nonlinear Monte Carlo model of collisionless shock structure with super-diffusive propagation of high-energy Fermi accelerated particles coupled to particle acceleration and MFA which affords a consistent description of strong shocks. A distinctive feature of the Monte Carlo technique is that it includes the full angular anisotropy of the particle distribution at all precursor positions. The model reveals that the super-diffusive transport of energetic particles (i.e., Levy-walk propagation) generates a strong quadruple anisotropy in the precursor particle distribution. The resultant pressure anisotropy of the high-energy particles produces a non-resonant mirror-type instability which amplifies compressible wave modes with wavelengths longer than the gyroradii of the highest energy protons produced by the shock.

description: Part of a collection of correspondence between Sir Herbert Read and Alfred Richard Orage. Orage is most well-known for editing the magazine “The New Age”. These letters, spanning 1921 and 1922, primarily discuss Read’s work as a Readers and Writers columnist for the magazine in that time. In these letters Orage also frequently mentions P. D. Ouspensky, who studied under philosopher G. I. Gurdjieff. In 1922 Orage sold “The New Age” and moved to Paris in order to also study under Gurdjieff. In this letter, Orage discusses Gilbert and the R. and W. column.
