Brain parcellation is important for exploiting neuroimaging data. Variability in physiology between individuals has led to the need for data-driven approaches to parcellation, with recent research focusing on simultaneously estimating and partitioning the network structure of the brain. We view data preprocessing, parcellation, and parcel validatio...

Understanding the mechanisms that control the body’s response to inflammation is of key importance, due to its involvement in myriad medical conditions, including cancer, arthritis, Alzheimer’s disease and asthma. While resolving inflammation has historically been considered a passive process, since the turn of the century the hunt for novel therap...

Background44Sc has been increasingly investigated as a potential alternative to 68Ga in the development of tracers for positron emission tomography (PET). The lower mean positron energy of 44Sc (0.63 MeV) compared to 68Ga (0.83 MeV) can result in better spatial image resolutions. However, high-energy γ-rays (1157 keV) are emitted at high rates (99....
Resolution is a key criterion in 6 degrees of freedom (DOF) precision positioning systems such as Gough Stewart platforms. Nevertheless, there is no consensus on the definition of resolution and its evaluation. We propose a resolution characterisation method for the 6 DOF precision positioning systems based on users' requirements (in telescope and ...
NMR spectroscopy is an essential analytical technique in metabolomics and fluxomics workflows, owing to its high structural elucidation capabilities combined with its intrinsic quantitative nature. However, routine NMR "omic" analytical methods suffer from several drawbacks that may have limited its use as a tool of choice, in particular when compa...

Given that micro-CT scanners have started being used for loess investigation, this study examines the reliability of the micro-CT technique for characterizing intact loess, aiming at the pore-size distribution (PSD) that is the most basic quantitative parameter of the soil structure. Intact loess from Xi’an, China was scanned with a micro-CT scanne...
Lagrangian coherent structures (LCSs) are the locally strongest repelling or attracting material lines and represent the cores of Lagrangian patterns that cannot be crossed by an ideal tracer. LCSs are a useful way to investigate material transport and have only recently been applied to coastal waters. Because coastal waters have complex boundaries...

Background: Data on the prevalence and clinical course of food protein-induced enterocolitis syndrome (FPIES) vary between populations and according to the culprit food. Objective: To evaluate the incidence, clinical characteristics, and remission patterns of FPIES among children in a Greek pediatric allergy referral center. Methods: We retrospecti...

Semi-preparative HPLC is one of the main techniques used for the purification of natural products (NPs). Generally, the sample has to be solubilized in organic solvent and injected on column through a loop valve. Since the solubility of crude natural extracts is often limited, a high solvent volume is needed for injection. This significantly compro...
In recent years, radioactive particle tracking (RPT) has emerged as a powerful noninvasive technique for characterization and visualization of flow in opaque multiphase flow reactors. This technique has been applied to a variety of multiphase flow reactors largely based on the theoretical framework for optimal design and performance parameters. No ...
