A targeted antiferromagnetic nanoprobe for ultra‐sensitive magnetic resonance imaging detection of sub‐millimeter esophageal tumors

open access: yesBMEMat, EarlyView.
We developed a cyclo‐RGD peptide‐conjugated antiferromagnetic nanoparticle (RANP) as a targeted T1 contrast agent. Under 9 T MRI conditions, RANP exhibited an r1 value of 1.88 mM−1 s−1 and a low r2/r1 ratio of 1.84, enabling the detection of esophageal tumors as small as 0.8 mm in vivo. Abstract Early, non‐invasive detection of esophageal cancer at sub‐

The impacts of biological invasions

open access: yesBiological Reviews, EarlyView.
ABSTRACT The Anthropocene is characterised by a continuous human‐mediated reshuffling of the distributions of species globally. Both intentional and unintentional introductions have resulted in numerous species being translocated beyond their native ranges, often leading to their establishment and subsequent spread – a process referred to as biological

Finite-size effect and the components of multifractality in financial volatility

open access: yes, 2009
Many financial variables are found to exhibit multifractal nature, which is usually attributed to the influence of temporal correlations and fat-tailedness in the probability distribution (PDF).

Itinerant-electron magnetism: the importance of many-body correlations

open access: yes, 2020
Do electrons become ferromagnetic just because of their repulisve Coulomb interaction? Our calculations on the three-dimensional electron gas imply that itinerant ferromagnetim of delocalized electrons without lattice and band structure, the most basic ...

Formalising Confluence in PVS [PDF]

open access: yes, 2016
Confluence is a critical property of computational systems which is related with determinism and non ambiguity and thus with other relevant computational attributes of functional specifications and rewriting system as termination and completion.

Gold Nanoparticles–Dynamic Constitutional Frameworks as Adaptive Hybrid Conjugates for Enzyme Immobilization

open access: yesChemistryEurope, EarlyView.
Dynamic constitutional frameworks (DCFs) and gold nanoparticles (AuNps) assemble into larger and well‐distributed conjugates providing an efficient platform for biosensing and biocatalytic applications. Dynamic constitutional frameworks (DCFs), connecting monomers via reversible covalent bonds, can initiate the assembly of gold nanoparticles (AuNps ...

The clinical value of MRI using single-shot echoplanar DWI to identify liver involvement in patients with advanced gastroenteropancreatic-neuroendocrine tumors (GEP-NETs), compared to FSE T2 and FFE T1 weighted image after i.v. Gd-EOB-DTPA contrast enhancement

open access: yesMedical Science Monitor, 2012
Summary Background To assess the detection rate of liver lesions in patients with advanced gastroenteropancreatic neuroendocrine carcinomas (GEP-NETs) using echo planar (EP) DWI (diffusion weighted imaging) as compared to standard FSE T2 wi and FFE T1 wi
