Quality of GNSS Traces from VGI: A Data Cleaning Method Based on Activity Type and User Experience
ISPRS International Journal of Geo-Information, 2020 VGI (Volunteered Geographic Information) refers to spatial data collected, created, and shared voluntarily by users. Georeferenced tracks are one of the most common components of VGI, and, as such, are not free from errors.

AFM observation of protein translocation mediated by one unit of SecYEG-SecA complex. [PDF]
Nat CommunProtein translocation across cellular membranes is an essential and nano-scale dynamic process. In the bacterial cytoplasmic membrane, the core proteins in this process are a membrane protein complex, SecYEG, corresponding to the eukaryotic Sec61 complex,

SecA, a remarkable nanomachine [PDF]
Cellular and Molecular Life Sciences, 2011 Biological cells harbor a variety of molecular machines that carry out mechanical work at the nanoscale. One of these nanomachines is the bacterial motor protein SecA which translocates secretory proteins through the protein-conducting membrane channel SecYEG.

Energetics of SecA Dimerization [PDF]
Journal of Molecular Biology, 2011 Transport of many proteins to extracytoplasmic locations occurs via the general secretion (Sec) pathway. In Escherichia coli, this pathway is composed of the SecYEG protein-conducting channel and the SecA ATPase. SecA plays a central role in binding the signal peptide region of preproteins, directing preproteins to membrane-bound SecYEG and promoting ...

Protein translocation by the SecA ATPase occurs by a power‐stroke mechanism
EMBO Journal, 2019 SecA belongs to the large class of ATPases that use the energy of ATP hydrolysis to perform mechanical work resulting in protein translocation across membranes, protein degradation, and unfolding.

Slow Steaming as Part of SECA Compliance Strategies among RoRo and RoPax Shipping Companies
Sustainability, 2019 Many geographically peripheral member states of the EU are critically dependent on short sea Roll-on/Roll-off (RoRo) and mixed freight–passenger (RoPax) shipping services for intra-European trade.
