TL;DR: In this article , the authors used Hyper Suprime Camera data (a precursor of what is to come with Rubin Observatory) to assess trail masking mitigation strategies for satellite contamination and found that the current routines largely mask satellite trails in single visits, but miss the extended low surface brightness features of the satellite trails.

TL;DR: In this article , a dual-drive plasmonic-organic-hybrid I/Q modulator on silicon photonics platform was used for coherent transmission of beyond 100 GBd signaling.
Abstract: We report on coherent transmission of beyond 100 GBd signaling based on plasmonic technology. Using dual-drive plasmonic-organic-hybrid I/Q modulator on silicon photonics platform, we demonstrate the successful transmission of 160-GBaud QPSK and 140-GBaud 16QAM modulations.

TL;DR: In this article , the authors analyze the new Mexican Energy Transition boosted by the government of the so-called Fourth Transformation of the National Public Life (4th Transformation), which took the chair in 2018.
Abstract: Abstract This chapter analyses the new Mexican Energy Transition boosted by the government of the so-called Fourth Transformation of the National Public Life (4th Transformation), which took the chair in 2018. The research evaluates both the return to the state monopoly over the energy sector cancelled by the constitutional reform of 2013 and those governmental actions aimed at discouraging investment in clean energies. In light of that evaluation, the survey discusses the implications of this new transition in Mexico’s international commitments regarding opening the energy sector, clean energies, and greenhouse gas emission reduction. In the same vein, the chapter assesses the impacts of the international context on the objectives of the 4th Transformation’s energy policy. In particular, it inquires about how the international Pandemic of COVID-19 influences the new Mexican Energy Policy.

TL;DR: The composición de las cinco piezas solistas se enfoc en el desarrollo de distintas técnicas de interpretación de la guitarra, como the tapping a two manos, armónicos, arpegios and fingerstyle as mentioned in this paper .
Abstract: Este proyecto artístico propone la composición de una obra para ensamble de cámara basada en la creación de cinco piezas para guitarra híbrida solista. En la obra para ensamble se explora el rol de la guitarra híbrida dentro de un formato de cámara. Los instrumentos que se escogieron para conformar el ensamble son flauta, saxofón tenor, cello, piano, batería y guitarra híbrida, instrumento que no ha sido explorado en la música de cámara. La composición de las cinco piezas solistas se enfoca en el desarrollo de distintas técnicas de interpretación de la guitarra, como el tapping a dos manos, armónicos, arpegios y fingerstyle. Sobre estas cinco piezas se delimitaron y conceptualizaron los principales criterios compositivos para llevarlos al ensamble. Palabras clave: Guitarra Híbrida. Ensamble Híbrido. Estudios para guitarra. Fingerstyle. Música Contemporánea. Música de Cámara.

TL;DR: Oceanit as discussed by the authors proposed a chemically resistant, water-and-oil repellent nanocomposite system that can be readily applied in-situ on natural gas transmission and distribution pipelines with a minimum of surface preparation.
Abstract: Addressing the current health of the nation’s existing 3 million miles of pipeline infrastructure is key to preventing further climate change. In 2020, natural gas production exceeded 34 trillion cubic feet (Tcf). Roughly 75% of natural gas consists of methane (CH4), which is up to 25 times more powerful than carbon dioxide (CO2) at trapping heat within the atmosphere over a 100-year period, and studies from the Environmental Defense Fund (EDF) estimate approximately 2% of all the natural gas produced will be lost during normal operations due to unaddressed leaks. This does not even consider the risks of major disaster due to pipeline failure, or the losses and extra fuel costs incurred due to corrosion and scale deposits in under-maintained pipelines. The objective of the proposed research is to demonstrate the protection capabilities and economic benefits of Oceanit’s internal pipe surface treatment, known as DragX™. DragX™ is a chemically resistant, water-and-oil repellent nanocomposite system that can be readily applied in-situ on natural gas transmission and distribution pipelines with a minimum of surface preparation. This makes it an ideal candidate for in-place retrofitting and refurbishment of existing pipelines without the need for expensive extraction and replacement. DragX™ is also able to significantly reduce the surface roughness, and subsequently, the frictional drag forces within a pipeline, improving throughput, decreasing energy costs of pressurization and pumping, and allowing for longer pipeline operation without interruption, reducing the methane emitted during pipe isolation and venting. As part of this project, Oceanit has utilized the Department of Energy’s support to fully develop, de-risk and prove the DragX™ core technology is both economically viable and commercially desirable to pipeline operators and energy companies alike. DragX™ material properties were optimized in this effort both for ease of applicability, to provide value in certain key parameters, and was demonstrated on pilot applications exceeding 2 miles in length. Beyond the already field demonstrated applications, this innovative nanocomposite surface treatment has the potential to be the backbone for CO2 and Hydrogen transporting pipeline infrastructure. The learnings from this project could accelerate the deployment of surface treatment technologies related to the energy transition infrastructure, thus benefitting the clean energy initiatives in the United States and all around the world.
