Re = Y −10.53 100 ~ 500 SPD [94] a The default value of CTE is αV, and the linear CTE is noted with αl. b XRD: X-ray diffraction; SPD: synchrotron powder X-ray diffraction; SCXRD: single-crystal X-ray diffraction. NPD: neutron powder diffraction. A more pronounced negative ...
Let K(r, s) denote a real continuous function defined on the square [r1 r2] X [r1, r2], which is strictly positive on the interior of this square. The eigenvalue problem (4.36)f(r)=λ∫r1r2K(r,s)f(s)ds, r1<r<r2, possesses a solutionλ1 > 0 which corresponds to an...
The SARS-CoV-2 epidemic in southern Africa has been characterized by three distinct waves. The first was associated with a mix of SARS-CoV-2 lineages, while the second and third waves were driven by the Beta (B.1.351) and Delta (B.1.617.2) vari

For mesenchymal stem cells (MSCs) cultured in three dimensional matrices, matrix remodeling is associated with enhanced osteogenic differentiation. However, the mechanism linking matrix remodeling in 3D to osteogenesis of MSCs remains unclear. Here, we f
In Sect. 3 we present a systematic study of the O(δ2), and classify the different contributions with respect to their UV behaviour. In Sect. 4 we consider higher order contributions to the Green's functions, and again classify them according to their UV behaviour. Section 5 is devoted ...
