A Compendium of Bona Fide Reference Markers for Genuine Plant Extracellular Vesicles and Their Degree of Phylogenetic Conservation. [PDF]

J Extracell Vesicles
ABSTRACT Although the field of plant EVs (PEVs) is experiencing exponential growth, rigorous characterisation complying with MISEV guidelines has not been yet implemented due to the lack of bona fide reference markers. In this work, we have paved the way for the standardisation of PEV markers, providing the most profound proteomic data so far from ...

Thermal noise lowers the accuracy of rotationally invariant harmonics of diffusion MRI data and their robustness to experimental variations. [PDF]

Magn Reson Med
Abstract Purpose Rotational invariants (RIs) are at the root of many dMRI applications. Among others, they are presented as a sensible way of reducing the dimensionality of biophysical models. While thermal noise impact on diffusion metrics has been well studied, little is known on its effect on spherical harmonics‐based RI (RISH) features and derived ...

Reproducibility and Reliability of Free-Water-Corrected Diffusion Tensor Imaging of the Brain: Revisited. [PDF]

Hum Brain Mapp
This paper explores different methodologies used to correct the diffusion tensor imaging (DTI) for the free‐water compartment, depending on whether the diffusion‐weighted magnetic resonance acquisitions are single‐ or multiple‐shell based, and evaluates the variability, reliability and separability properties of free‐water‐corrected DTI in the healthy ...

Collected worker experiences, knowledge management practices and service innovation in urban Norway

Papers in Regional Science, Volume 100, Issue 6, Page 1501-1525, December 2021., 2021
Abstract Knowledge‐intensive services firms prefer to locate in cities that provide access to rich information flows and abundant opportunities for learning‐by‐recruiting. Focusing specifically on such locations, this paper explores how innovation is associated with work experiences “collected” by employees through their recent career paths and the ...
