Optimization of Selective Radio Frequency Pulses for Simultaneous Multi-Slice MRI

Chinese Journal of Magnetic Resonance, 2018
Simultaneous multi-slice magnetic resonance imaging (MRI) has attracted much research interests recently due to its advantages in increasing signal-to-noise ratio (SNR) and decreasing acquisition time.

Generalized nonorthogonal matrix elements. II: Extension to arbitrary excitations

The Journal of Chemical Physics, 2022
Electronic structure methods that exploit nonorthogonal Slater determinants face the challenge of efficiently computing nonorthogonal matrix elements. In a recent publication [H. G. A. Burton, J. Chem. Phys. 154, 144109 (2021)], I introduced a generalized extension to the nonorthogonal Wick’s theorem that allows matrix elements to be derived between ...

ZW4864‐mediated inhibition of the β‐catenin/BCL9/BCL9L complex reveals therapeutic potential in bladder cancer

Molecular Oncology, EarlyView.
BCL9 and BCL9L drive bladder cancer progression by enhancing β‐catenin signaling, promoting proliferation, migration, invasion, and organoid growth. Genetic depletion of BCL9(L) suppresses malignant phenotypes, while pharmacological disruption of the β‐catenin/BCL9(L) complex with ZW4864 inhibits canonical Wnt signaling and tumor‐associated cellular ...

Raman‐based label‐free microscopic analysis of the pancreas in living zebrafish larvae

FEBS Open Bio, EarlyView.
Forward stimulated Raman scattering (F‐SRS) and epi coherent anti‐Stokes Raman scattering (E‐CARS) allow label‐free discrimination of distinct subcellular structures in the pancreas of living zebrafish larvae. Given the straightforward applicability, we anticipate broad implementation of Raman microscopy in other organs and across various biomedical ...

Meson excitation at finite chemical potential

European Physical Journal C: Particles and Fields, 2019
We consider a probe stable meson in the holographic quark–gluon plasma at zero temperature and chemical potential. Due to the energy injection into the plasma, the temperature and chemical potential are increased to arbitrary finite values in such a way ...
