Selfish & Opaque Transaction Ordering in the Bitcoin Blockchain: The Case for Chain Neutrality [PDF]

open access: yesIn Proceedings of the ACM SIGCOMM Internet Measurement Conference (IMC 2021), 2021
Most public blockchain protocols, including the popular Bitcoin and Ethereum blockchains, do not formally specify the order in which miners should select transactions from the pool of pending (or uncommitted) transactions for inclusion in the blockchain. Over the years, informal conventions or "norms" for transaction ordering have, however, emerged via

Assessing the theory-data tension in neutrino-induced charged pion production: the effect of final-state nucleon distortion [PDF]

open access: yes, 2022
Pion production on nuclei constitutes a significant part of the total cross section in experiments involving few-GeV neutrinos. Combined analyses of data on deuterium and heavier nuclei points to tensions between the bubble chamber data and the data of the MINER$\nu$A experiment, which are often ascribed to unspecified nuclear effects.

Aquamarine from Massangana batholith, Rondônia State: mineral chemistry and fluid inclusion data

open access: yesREM: International Engineering Journal, 2020
Beryl is usually found in granite-pegmatite systems. The addition of chromophore elements (V, Cr, Mn, Fe) into the crystalline structure favors color changes in beryl and thus generates some of the world’s expensive gems such as emerald, morganite ...

Composition, Mineral and Fatty Acid Profiles of Milk from Goats Fed with Different Proportions of Broccoli and Artichoke Plant By-Products

open access: yesFoods, 2020
In the Mediterranean region, artichoke and broccoli are major crops with a high amount of by-products that can be used as alternative feedstuffs for ruminants, lowering feed costs and enhancing milk sustainability while reducing the environmental impact ...

Three-dimensional distribution of primary melt inclusions in garnets by X-ray microtomography [PDF]

open access: yes, 2018
open6X-ray computed microtomography (X-mu CT) is applied here to investigate in a non-invasive way the three-dimensional (3D) spatial distribution of primary melt and fluid inclusions in gamets from the metapeitic enclaves of El Hoyazo and from the ...

PERFIL METABÓLICO EM OVINOS ALIMENTADOS COM INCLUSÕES CRESCENTES DA TORTA DO BABAÇU NA DIETA

open access: yesVeterinary News, 2014
The objective was to evaluate the effect of inclusion of babassu pie in sheep feeding on the energy, protein and mineral metabolism, as well as, the effect of collection period on these variables.Twenty males intact sheep were assigned to four ...

How large are departures from lithostatic pressure? Constraints from host-inclusion elasticity [PDF]

open access: yes, 2015
Minerals trapped as inclusions within other host minerals will develop non-lithostatic pressures during both prograde and retrograde metamorphism because of the differences between the thermo-elastic properties of the host and inclusion phases.

Effect of the Inclusion of Organic Copper, Manganese, And Zinc in The Diet of Layers on Mineral Excretion, Egg Production, and Eggshell Quality

open access: yesBrazilian Journal of Poultry Science, 2015
This study aimed at evaluating the replacement of inorganic copper, manganese, and zinc sources by organic sources in the diet of laying hens during the second laying cycle in trace mineral excretion, egg production, and eggshell quality. Two hundred and

Subduction-related oxidation of the sublithospheric mantle evidenced by ferropericlase and magnesiowüstite diamond inclusions

open access: yesNature Communications, 2022
This article reports finding of a highly oxidised mineral in diamond inclusion derived from mantle transition zone or lower mantle, very reduced areas on our planet. Such oxidised material is likely linked to subduction of carbonates into this region.
