Students’ perceptions of the practice firms network learning environment in Brazil : a phenomenographic approach
… the Practice Firms Network Learning Environment (PFN), describe their relationship with this learning environment. In the PFN model students conceptualise, design and sell ‘virtual’ products and services to other people within the model, constituting a market that only exists by the pedagogical …

Low temperature synthesis and properties of lead ferroniobate Pb(Fe<sub>0.5</sub>Nb<sub>0.5</sub>)O₃
… Pb(Fe<sub>0.5</sub>Nb<sub>0.5</sub>)O₃ (PFN) powders were successfully formed by molten salt synthesis using mixture of NaCl and KCI salts. Lower temperatures and shorter times (0.5 hour at 800°C) were needed for single phase PFN formation from molten salts relative to those required for …

FN-EDA domain knock-in and knock-out mice, as a model for the study of the hepatic fibronectin (FN) functions
… tissue extracellular matrices (ECM). Plasma FN (pFN) is produced and secreted into the bloodstream by the liver. Liver ECM-FN and pFN are characte,rized by the absence of the EDA domain, one of the three FN exons undergoing alternative splicing. However, in pathological situations such as wound …

High Pressure Hydrodynamic Shock Wave Effects on Tenderness of Early Deboned Broiler Breasts
… were treated with one Pulse Firing Network (PFN) or two PFN and 45 % Energy. Breasts treated with one PFN were not different than controls. Broiler breasts exposed to two PFN were 22 % more tender and different from the controls. Turkey breast portions exposed to two PFN and 72% Energy were …

Phenotypic characterization of stress Leukocytosis
… Chapter four showed that a perforin (pfn)+ C27 phenotype in CD4+, CD8+ and γδ T cells consistency identified cells most sensitive to stress and isoproterenol induced mobilization. However, although cytotoxicity (pfn+) was important, differentiation (CD27 ) status better predicted …

Mixed-Variable Bayesian Optimization using Prior-Data Fitted Networks
… and scalability. Prior-Data Fitted Networks (PFNs) have recently emerged as a promising alternative, leveraging transformer architectures and in-context learning to approximate posterior predictive distributions (PPDs) in a single forward pass. By training on large amounts of synthetically …

Two phase magnetoelectric epitaxial composite thin films
… Epitaxial thin-layers of Pb(Fe1/2Nb1/2)O3 (or PFN) grown on (001), (110), and (111) SrTiO3 substrates are tetragonal, orthorhombic, and rhombohedral respectively. The larger constraint stress induces higher piezoelectric constants in tetragonal PFN thin film. Epitaxial thin-layers of …
