PURPOSE: Dynamic contrast enhanced (DCE) MRI requires high spatial resolution for morphological information and high temporal resolution for contrast pharmacokinetic modeling. The current fast imaging techniques [1-5] have shown success in improving the temporal resolution of DCE-MRI. However, it is still challenging to improve both the spatial and temporal resolutions simultaneously. This abst...

Dynamic contrast enhanced MRI requires high spatial resolution for morphological information and high temporal resolution for contrast pharmacokinetics. The current techniques usually have to compromise the spatial information for the required temporal resolution. This paper presents a novel method that effectively integrates sparse sampling, parallel imaging, partial separable (PS) model, and ...

A mixed s-stack q-queue layout of a graph consists linear order its vertices and partition edges into s stacks q queues, such that no two in the same stack cross queue nest. In 1992, Heath Rosenberg conjectured every planar admits 1-stack 1-queue layout. Recently, Pupyrev disproved this by demonstrating partial 3-tree does not admit note, we strengthen Pupyrev's result showing conjecture hold e...

Methods: Acquisition. A balanced steady-state free precession (bSSFP) sequence using a 3-dimensional (3D) golden angle radial acquisition order was implemented for acquisition of an image volume covering the whole heart (GRATE). The sequence was used to image 8 healthy volunteers during free breathing and over several cardiac and respiratory cycles. A stack of short-axis (SA) slices, as well as...

In the title compound, C(22)H(26)O(3), the dihedral angle between the cyclo-propane ring and the plane of the vinyl group is 88.2 (2)°. The dihedral angle between the phenyl and furan rings is 86.09 (8)°. In the crystal, weak inter-molecular C-H⋯π contacts together with very weak C-H⋯O hydrogen bonds stack the mol-ecules along the a axis.

In the solid state, the title compound, C(22)H(10)N(2)S, forms centrosymmetric dimers by pairs of non-classical C-H⋯S hydrogen bonds linking approximately coplanar mol-ecules. The benzene ring involved in this inter-action makes a dihedral angle of only 7.21 (16)° with the thio-phene ring, while the other benzene ring is twisted somewhat out of the plane, with a dihedral angle of 39.58 (9)°. Th...

In the title compound, C26H22N2O5, the system consisting of five fused rings, being essentially planar with an r.m.s. deviation from the least-squares plane of 0.049 (3) Å, makes a dihedral angle of 58.72 (12)° with the plane of the ethyl carboxyl-ate group immediately attached to it, and a dihedral angle of 89.48 (14)° with the plane of the ethyl carboxyl-ate group attached via the -CH2- bridg...

In the title compound, C(15)H(11)N(3)O, the dihedral angle betwen the heterocyclic rings is 9.23 (5)° and the dihedral angle between the benzoyl and pyrazole rings is 58.64 (5)°. In the crystal, inversion dimers linked by pairs of C-H⋯O hydrogen bonds generate R(2) (2)(10) loops. The dimers stack into a column running parallel to the b-axis direction.

Factors that influence the orientation of the mitotic spindle are important for the maintenance of stem cell populations and in cancer development. However, screening for these factors requires rapid quantification of alterations of the angle of the mitotic spindle in cultured cell lines. Here we describe a method to image mitotic cells and rapidly score the angle of the mitotic spindle using a...
