During developmental stages, biomechanical stimuli on cardiac cells modulate genetic programs, and deviations from normal stimuli can lead to cardiac defects. Therefore, it is important to characterize normal cardiac biomechanical stimuli during early developmental stages. Using the chicken embryo model of cardiac development, we focused on characterizing biomechanical stimuli on the Hamburger-...

We present a direct measurement of the parity-violating parameter Ab by analyzing the left-right forward-backward asymmetry of b quarks in e+ e– + 2° + b;. The SLD experiment observes hadronic decays of 2° bosons produced at resonance in collisions of longitudinally polarized. . elect rons and unpolarized positrons at the SLC. Heavy flavor decays of the 2° are identified by taking advantage of ...
