Provenance for Aggregate Queries [PDF]
, 2011 We study in this paper provenance information for queries with aggregation. Provenance information was studied in the context of various query languages that do not allow for aggregation, and recent work has suggested to capture provenance by annotating ...

Aggregating the aggregators – An agnostic approach [PDF]
Information Services & Use, 2004 A data warehouse platform for automatic post-processing and post-aggregation of online search results and alerts from online vendors was developed, called Web Alerts. Contents from many information providers are being repackaged "agnostically". The solution, built on the Lotus Notes & Domino groupware, is automatically receiving, parsing, aggregating ...

FEBS Letters, EarlyView.LHCPs are transported to the thylakoid membrane via the (cp)SRP pathway. This process involves a transit complex of (cp)SRP43, (cp)SRP54 and LHCP, which interacts with (cp)FtsY and Alb3 at the membrane. GTP hydrolysis by (cp)SRP54 and (cp)FtsY triggers complex dissociation.

Advanced Science, 2020 Hyperbranched polymers constructed from CO2 possess unique architectures and properties; however, they are difficult to prepare. In this work, CO2‐based, hyperbranched poly(alkynoate)s (hb‐PAs) with high molecular weights and degrees of branching are ...

Premicellar aggregation of amphiphilic molecules: Aggregate lifetime and polydispersity [PDF]
J. Chem. Phys. 130, 114901 (2009), 2008 A recently introduced thermodynamic model of amphiphilic molecules in solution has yielded, under certain realistic conditions, a significant presence of metastable aggregates well below the critical micelle concentration -- a phenomenon that has been reported also experimentally.

Taurine promotes glucagon‐like peptide‐1 secretion in enteroendocrine L cells
FEBS Letters, EarlyView.Taurine, a sulfur‐containing amino acid, is likely taken up by enteroendocrine L cells via the taurine transporter. This process increases the levels of cytosolic ATP. The increase in intracellular Ca2+ concentrations and glucagon‐like peptide‐1 secretion through membrane depolarization is caused by the closure of ATP‐sensitive potassium channels ...

Aggregation for Gaussian regression
, 2007 This paper studies statistical aggregation procedures in the regression setting. A motivating factor is the existence of many different methods of estimation, leading to possibly competing estimators. We consider here three different types of aggregation:

Making tau amyloid models in vitro: a crucial and underestimated challenge
FEBS Letters, EarlyView.This review highlights the challenges of producing in vitro amyloid assemblies of the tau protein. We review how accurately the existing protocols mimic tau deposits found in the brain of patients affected with tauopathies. We discuss the important properties that should be considered when forming amyloids and the benchmarks that should be used to ...
