The article reports on the discovery of ceramic kilns in the archaeological complex of Atzompa in Monte Albán, Oaxaca. These kilns have similar characteristics to those of the ethnographic tradition of Atzompa and it is believed that they were used to produce large gray ceramic pots. An archaeomagnetic study conducted on one of the kilns indicates that it was used after the supposed abandonment of Monte Albán, suggesting that the inhabitants of Atzompa continued to manufacture ceramics. Additionally, evidence of specialization in ceramic production in Atzompa and a permanent relationship between Atzompa and Monte Albán were found. The study was funded by the CONAHCyT CF19-1761 project and UNAMDGAPA PAPIIT IN100224. [Extracted from the article]

The use of vertical axis wind turbines to electrify homes without electricity in the Peruvian region of Junín is essential to address the challenges of climate change and move towards a more sustainable and environmentally friendly future. The objective was set to compare three types of wind turbines, these are Darrieus H, Savonius, and Windside concerning to the wind speeds that occur in the Junín region. This is because the operation of these wind turbines in this region is not yet known. The following procedure was tracked: first, the design was made and then it was experimented in the wind tunnel laboratory of the Faculty of Electrical and Electronic Engineering of the National University of Central Peru. In the study, we took into account that there is indeterminacy in the variable wind speed among others, which is why we adapted the traditional variables to the use of neutrosophic numbers. Additionally, we carried out a comprehensive study that includes other variables for decision-making. To select the best complete option we asked a group of 3 experts for their evaluations according to several criteria and we used the VIKOR method for intervals adapted to neutrosophic numbers.

This paper aims to investigate whether social skills are a factor related to emotion management since inadequate emotion management is causing mental illnesses in this century, such as stress and depression. The objective was to determine the relationship between social skills and emotional management in students at the National University of Central Peru. To estimate social skills, the scales proposed by the Technical Team of the Department of Mental Health Promotion and Prevention of Psychosocial Problems of Peru were applied to a random sample of 184 from a population of 352 students. The variable of adequate management of emotions was measured using an Indeterminate Likert Scale since we consider that emotion has multiple components and therefore it is more precise to measure it when all the components are taken into account at the same time. To process the collected data, plithogenic statistics were applied that allow the study of events of a multivariate nature in an indeterminate framework. [ABSTRACT FROM AUTHOR]

The decay of the low‐mode internal tide due to the superharmonic energy cascade is investigated in a realistically forced global Hybrid Coordinate Ocean Model simulation with 1/25° (4 km) horizontal grid spacing. Time‐mean and depth‐integrated supertidal kinetic energy is found to be largest near low‐latitude internal tide generation sites, such as the Bay of Bengal, Amazon Shelf, and Mascarene Ridge. The supertidal kinetic energy can make up to 50% of the total internal tide kinetic energy several hundred kilometers from the generation sites. As opposed to the tidal flux divergence, the supertidal flux divergence does not correlate with the barotropic to baroclinic energy conversion. Instead, the time‐mean and depth‐integrated supertidal flux divergence correlates with the nonlinear kinetic energy transfers from (sub)tidal to supertidal frequency bands as estimated with a novel coarse‐graining approach. The regular spaced banding patterns of the surface‐intensified nonlinear energy transfers are attributed to semidiurnal mode 1 and mode 2 internal waves that interfere constructively at the surface. This causes patches where both surface tidal kinetic energy and nonlinear energy transfers are elevated. The simulated internal tide off the Amazon Shelf steepens significantly near these patches, generating solitary‐like waves in good agreement with Synthetic Aperture Radar imagery. Globally, we find that regions of high supertidal energy flux also show a high correlation with observed instances of internal solitary waves. Plain Language Summary: Ocean tides generate internal waves at steep ridges and continental shelves in a stratified ocean. In some regions with strong tidal forcing, surface intensified stratification, and weak background rotation, these waves are observed to steepen into solitary‐like waves. In this process, energy is transferred from the tidal band to higher (supertidal) frequencies and wavenumbers. This study investigates "internal tide steepening" in a realistically forced global Hybrid Coordinate Ocean Model (HYCOM) simulation with a 4‐km horizontal grid spacing. In our simulation, supertidal internal wave energy accounts for about 5% of the total energy available to internal tides equatorward of ±25°. However in some regions, such as the Amazon Shelf and Bay of Bengal, this ratio can be as much as 50%. Along the internal tide beams, the supertidal energy transfers are enhanced in regular spaced "patches" where longer and faster mode 1 semidiurnal internal tides overtake the shorter and slower mode 2 internal tides. In these patches the surface velocities of these waves constructively superpose, enhancing the surface kinetic energy and nonlinear energy transfers. At the Amazon Shelf, sharp‐crested solitary‐like waves that emerge in these patches in the HYCOM simulation are in good agreement with satellite observations. Although nonlinear internal tides are simulated in our global ocean model simulation, higher resolutions are needed to better resolve the energy cascade to smaller scales. Key Points: Supertidal energy (>2.67 cycles per day [cpd]) is elevated at low latitudes, making up to 50% of total tidal energy (>0.9 cpd) in some areasSupertidal flux divergence and surface tidal energy reveal banding patterns due to the interaction between mode 1 and 2 internal tidesSupertidal flux divergence is due to energy transfers from internal tides to higher‐harmonic frequencies as computed with coarse graining [ABSTRACT FROM AUTHOR]
