Resumo Em Rikbaktsa (Macro-Jê), as partículas constituem uma classe léxica, ao lado de advérbios e posposições. Em geral, as partículas são descritas como elementos invariáveis; nesta língua, entretanto, há dois conjuntos de partículas, um marcando ...

Hurricanes create major disturbances to stream ecosystems by producing large floods and removing riparian vegetation. Understanding their impacts is a priority, as hurricane intensity will increase with global climate change. Hurricane disturbance shifts mayfly assemblages from dominance by Leptophlebiidae before to Baetidae after.

Flavor in SU(5)$SU(5)$ Finite Grand Unified Models
Abstract Four SU(5)N=1$SU(5) \nobreakspace N=1$ supersymmetric models which exhibit S3$S_3$ and/or ZN$Z_N$ symmetries are studied, that are finite to two or all loops, and their corresponding mass matrices. The first is an all‐loop finite model based on an S3×Z3×Z2$S_3\times Z_3\times Z_2$ flavor symmetry, which leads to phenomenologically nonviable ...

Modelo de quarks e sistemas multiquarks [PDF]
A descoberta de muitas partículas, especialmente nos anos 50, com o surgimento de novos aceleradores, causou a busca por um modelo que descrevesse de forma simplificada o conjunto de partículas conhecidas.

Despite the critical role of biological soil crusts (biocrusts) in dryland C and N cycles, little is known about how biocrust‐derived C and N move into the soil. This study reveals how biocrusts facilitate the downward movement of C and N and drive the formation of mineral‐associated organic matter in subcrust soils.

Small free field inflation in higher curvature gravity
Within General Relativity, a minimally coupled scalar field governed by a quadratic potential is able to produce an accelerated expansion of the universe provided its value and excursion are larger than the Planck scale.
