Viable entanglement detection of unknown mixed states in low dimensions

We explore procedures to detect entanglement of unknown mixed states, which can be experimentally viable. The heart of the method is a hierarchy of simple feasibility problems, which provides sufficient conditions to entanglement. Our numerical investigations indicate that the entanglement is detected with a cost which is much lower than full state tomography. The procedure is applicable to both free and bound entanglement, and involves only single copy measurements.Comment: 8 pages, 9 figures, 4 table

Researches is health of Pirarucu, Arapaima gigas: partnership between EMBRAPA-SEBRAE.

Aiming to deepen the scientific knowledge on health aspects of pirarucu, and attempting to improve the fingerlings survival rates a partnership was signed between SEBRAE and EMBRAPA, in collaboration with the UFT

Changing the production chain of Amazonian pirarucu.

This article summarizes these recent findings and envisions how these are impacting the production sector in the short and medium terms. Recent studies in Brazil have addressed the main challenges faced by commercial producers of pirarucu, including breeding, larval rearing, grow-out, feeding, health management, processing and more

Nature of the constant factor in the relation between radial breathing mode frequency and tube diameter for single-wall carbon nanotubes

Resonance Raman scattering is used to determine the radial breathing mode (RBM) frequency (ωRBM) dependence on tube diameter (dt) for single-wall carbon nanotubes (SWNTs). We establish experimentally the ωRBM=227.0/dt as the fundamental relation for pristine SWNTs. All the other RBM values found in the literature can be explained by an upshift in frequency due mostly to van der Waals interaction between SWNTs and environment

Infecções por acantocéfalos: um problema para a produção de peixes.

Os peixes podem apresentar enfermidades de diversas origens em sistemas de criação intensiva, com destaque para as doenças parasitárias . Entre os principais grupos de parasitos que causam doenças em pisciculturas brasileiras estão os protozoários, mixosporídeos, crustáceos e helmintos, que ao encontrarem condições favoráveis, proliferam‐se causando doenças Dentre os helmintos, os acantocéfalos vêm chamando a atenção dos piscicultores em razão das altas infestações registradas na região Norte do Brasil
