A bstract We analyze the BPS equations in “superstratum sector” of three-dimensional gauged supergravity. obtain multi-parameter supersymmetric solutions that include elliptical deformations supertubes underlie standard superstrata. uplift to corresponding six-dimensional geometries. This yields new families elliptically-deformed, ambi-bolar hyper-Kähler geometries four dimensions with a non-tr...

Arctic wildlife resource management must secure biodiversity without infringing on indigenous hunting rights. The article focuses the bottlenecks in of game species hunted by population.

Three main problems are di...

We propose a worldsheet description for the ${\rm AdS}_5\times {\rm S}^5$ string theory dual to large $N$, free ${\cal N}=4$ super Yang-Mills in four dimensions. The is natural generalisation of recently investigated tensionless on AdS}_3\times S}^3\times \mathbb{T}^4$. As case AdS}_3$ it has field description, with spectrally flowed sectors, and closely related an (ambi-)twistor theory. Here, ...

Studies on the sustainability of aquaculture have been carried out around world. The input organic matter in sediment and influence current velocity deposition particles produced by fish captivity can be used to assess distribution benthic assemblages below marine farms. Sediment organisms were collected April, September December 2019 August October 2020 farming area two control areas Bananal c...
