TL;DR: In this article, the basic physical notions underlying microwave sintering and the theoretical and numerical models of the microwave Sintering process are discussed and the significance of microwave nonthermal effects in sinterings is demonstrated based on the experimental results, and models of such effects are reviewed.
Abstract: This paper reviews the basic physical notions underlying microwave sintering and the theoretical and numerical models of the microwave sintering process. The propagation and absorption of electromagnetic waves in materials, and the distribution of electromagnetic field in cavity resonators that serve as applicators for microwave processing are discussed and the electromagnetic modeling of such applicators is reviewed. The microwave absorption properties of ceramic and metal powder materials and the methods of their description are addressed. Self-consistent electromagnetic and thermal models that are capable of predicting the temperature distribution in the microwave-heated materials and dynamic effects such as thermal runaway instabilities are reviewed. The multiphysics simulations that combine electromagnetic, thermal, and sintering models and result in predicting densification, shrinkage, and grain structure evolution are discussed in detail. The significance of microwave nonthermal effects in sintering is demonstrated based on the experimental results, and the models of such effects are reviewed.

TL;DR: In this article, the authors introduce the physical notions and the mathematical methods that are relevant to the study of nonlinear waves in Bose-Einstein condensates (BECs).
Abstract: The aim of this review is to introduce the reader to some of the physical notions and the mathematical methods that are relevant to the study of nonlinear waves in Bose–Einstein condensates (BECs). Upon introducing the general framework, we discuss the prototypical models that are relevant to this setting for different dimensions and different potentials confining the atoms. We analyse some of the model properties and explore their typical wave solutions (plane wave solutions, bright, dark, gap solitons as well as vortices). We then offer a collection of mathematical methods that can be used to understand the existence, stability and dynamics of nonlinear waves in such BECs, either directly or starting from different types of limits (e.g. the linear or the nonlinear limit or the discrete limit of the corresponding equation). Finally, we consider some special topics involving more recent developments, and experimental setups in which there is still considerable need for developing mathematical as well as computational tools.

TL;DR: It is proposed that marine–sediment viral communities are one of the largest unexplored reservoirs of sequence space on the planet.
Abstract: Viruses, most of which are phage, are extremely abundant in marine sediments, yet almost nothing is known about their identity or diversity. We present the metagenomic analysis of an uncultured near–shore marine–sediment viral community. Three–quarters of the sequences in the sample were not related to anything previously reported. Among the sequences that could be identified, the majority belonged to double–stranded DNA phage. Temperate phage were more common than lytic phage, suggesting that lysogeny may be an important lifestyle for sediment viruses. Comparisons between the sediment sample and previously sequenced seawater viral communities showed that certain phage phylogenetic groups were abundant in all marine viral communities, while other phage groups were under–represented or absent. This ‘marineness’ suggests that marine phage are derived from a common set of ancestors. Several independent mathematical models, based on the distribution of overlapping shotgun sequence fragments from the library, were used to show that the diversity of the viral community was extremely high, with at least 10 4 viral genotypes per kilogram of sediment and a Shannon index greater than 9 nats. Based on these observations we propose that marine–sediment viral communities are one of the largest unexplored reservoirs of sequence space on the planet.

TL;DR: Evidence suggests that F&V have the strongest effects in relation to prevention of CVDs, noting a nonlinear threshold effect of 800 g per day (i.e., about 5 servings a day).
Abstract: Fruit and vegetables (FV the 2015–2020 U.S. Dietary Guidelines for Americans recommend that F&V constitute one-half of the plate at eac...
