Grassland Geopoetics: Son Jarocho and the Black Sense of Place of Plantations and Pastures

This essay considers how the grasslands of the Mexican region of El Sotavento entangle with the history of racial capitalism and with traditional Sotaventine music. Throughout this text, I argue that son Jarocho music and its poetics counterpoint racist colonial discourses making space for ways of being beyond racial capitalism. I review the history of Sotaventine grasslands, counterpointing their historical becomings with ethnographic materials and current poetic expressions. I especially focus on two sones: La Caña, written in the 1990s by Patricio Hidalgo Belli regarding sugarcane, and the 18th century Toro Zacamandú that speaks of cowboying. Using scholarly writings on the plantation and plantation histories from McKittrick and Glissant, King's work on fungibility, scholarship on Maroon landscapes and marronage, and an array of writers who explore poetics and geopoetics, we shall see how racial capitalism and the historical becomings of plantations and pastures are reflected and overturned in Sotaventine sounds

Double-Virtual NNLO QCD Corrections for Five-Parton Scattering: The Quark Channels

We complete the computation of two-loop helicity amplitudes required to obtain next-to-next-to-leading order QCD corrections for three-jet production at hadron colliders, including all contributions beyond the leading-color approximation. The analytic expressions are reconstructed from finite-field samples obtained with the numerical unitarity method. We find that the reconstruction is significantly facilitated by exploiting the overlaps between rational coefficient functions of quark and gluon processes, and we display their compact generating sets in the appendix of the paper. We implement our results in a public code, and demonstrate its suitability for phenomenological applications.Comment: 29 pages, 1 figure, 5 tables - ancillaries at https://doi.org/10.5281/zenodo.10227001 and numerical code at https://gitlab.com/five-point-amplitudes/FivePointAmplitudes-cpp. arXiv admin note: text overlap with arXiv:2311.1008

Acoustic oscillations in stars near the tip of the red giant branch

Small amplitude oscillations are observed in red giant branch (RGB) stars. Data on such oscillations are a source of information about the objects, notably about properties of convection in their envelopes and about the systems these objects inhabit. The OGLE-III catalog contains data for about 80 thousand small amplitude variable red giants (OSARGs) in the Large Magellanic Cloud. We want to explain variability in OSARGs as the solar-like oscillation and to associate the peaks in power spectra with frequencies of acoustic modes. We use data on reddening-free magnitudes of the objects and interpret them in terms of stellar physical parameters using tabulated isochrones calculated for ages and composition parameters corresponding to the upper RGB of the LMC. Massive data on the peak frequencies and amplitudes are compared with expectations for stochastically excited oscillations. The frequencies are also compared with those calculated for radial modes in envelope models with parameters taken from the isochrones. In stars close to the tip of the RGB, the peaks in power spectra are found in the 0.1-1.0 $\mu$Hz range, which is consistent with extrapolation of the frequency-luminosity relation for the solar-like oscillation. The dominant peaks occur close to the first two radial overtones. The increase in amplitude with luminosity is slower than linear. The exponent s=0.9 is similar to what is found from recent analysis of CoRoT data on less luminous red giants. Frequency separations between dominant peaks are found to be smaller by about 20% than calculated separations between these modes. After examining various possibilities, we left this discrepancy unexplained. The small amplitude variability of stars at the RGB tip is likely to be caused by a stochastic excitation of acoustic oscillations, but interpreting of individual peaks in power spectra presents a problem.Comment: Accepted for publication in Astronomy and Astrophysics, 6 pages, 6 figure

CONCEPTUAL MODEL OF INTEGRAL INNOVATION FOR DEVELOPERS, WITHIN THE SUPPLY OF AUTO PARTS IN EMERGING COUNTRIES: A SYSTEMATIC REVIEW

The objective of this article is the development of a proposal for a comprehensive conceptual model of innovation for developers, within the supply of auto parts in the context of emerging economies, based on a systematic review of innovation capabilities. For this purpose, prestigious digital sources were used to collect and select related literature, taking into account global quality metrics; the results yielded a selection of 50 articles that address in depth the research constructs with updated studies, and that include both the contexts of the research objective and alternative contexts with important theoretical contributions; The results of the systematic review also clearly show a classification of internal and external factors of the organizations, which influence the dimensions of innovation capacity and developed constructs, as well as their role in a proposal that integrates them in a conceptual model for managing innovation, using the theoretical bases of open innovation and the PDCA cycle
