Lower bounds for multi-pass processing of multiple data streams [PDF]

, 2009
This paper gives a brief overview of computation models for data stream processing, and it introduces a new model for multi-pass processing of multiple streams, the so-called mp2s-automata.

Development and validation of an alternative method for ergosterol determination in alder leaves using liquid-liquid extraction and LC-MS/MS after saponification

MethodsX
Ergosterol is widely used as proxy for the estimation of leaf litter associated fungal biomass. According to a common textbook method, ergosterol can be extracted from plant tissue with methanolic potassium hydroxide followed by purification with solid ...

Change detection in categorical evolving data streams

, 2014
Detecting change in evolving data streams is a central issue for accurate adaptive learning. In real world applications, data streams have categorical features, and changes induced in the data distribution of these categorical features have not been ...

A ocorrência de fluxos no perfil vertical do vento na baixa atmosfera e seu efeito na intensidade do índice "K" The occurrence of streams in the lower-atmosphere vertical wind profile and of their effect to intensity of the "K" index

Revista Brasileira de Meteorologia, 2007
Neste estudo objetivou-se caracterizar a influência dos fluxos/Jatos de Nível Baixo (JNB) nos níveis de 850 e 950 hPa com o índice "K". O mecanismo associado aos fluxos/JNB realiza um transporte de calor e vapor de água, aumentando o conteúdo de umidade ...

Salmonella lipopolysaccharide‐containing supported lipid bilayers as platforms to study bacteriophage interactions

FEBS Letters, EarlyView.
We present robust protocols for the preparation of supported lipid bilayers (SLBs) incorporating either Salmonella smooth LPS or outer membrane vesicles (OMVs). We use a combination of quartz crystal microbalance with dissipation (QCM‐D) and fluorescence microscopy to both characterize the SLBs of various compositions and to probe their interactions ...
