Cell-based therapeutics are an emerging modality with the potential to treat many currently intractable diseases through uniquely powerful modes of action. Despite notable recent clinical and commercial successes, cell-based therapies continue to face numerous challenges that limit their widespread translation...
The author, Lewis Caroll, describes an amazing creature in the famous fairy tale Alice’s Adventures in Wonderland. It___the way of giving Alice’s own thimble (顶针) as a gift for herself, leaving the children readers a strong impression.___, when the kids try to search for this crea...
of a Lewis structure. The agreement is best at the HartreeFock level, where the Fermi hole is the sole source of correlation between the electrons. The introduction of the remaining correlation, the Coulomb correlation, disrupts the sharing of electron pairs between the atoms, and its effect is...
The Home of My People When Lewis and Clark stepped onto the Weippe Prairie in present-day Idaho in September 1808, they met the Nez Perce Indians. In the following years, the white explorers(探险者)began to fight with the Indians for their land. Some Nez Perce chiefs signed agreements with...
Toward that end, we set up a model that describes the dispersion of air pollutants in a small region (< 1 km long) near the ground surface (< 250 m high). It consists of a neutrally stratified model modified to account for the atmospheric stability effects by imposing the near-...

(probe 1.70 eV)43. A single-exponential behavior describes the kinetics of the band edge bleaching with lifetimeτ1 = 4 ± 1 ns. Using a push energy of 1.03 eV (1 mJ cm−2) at 3 ps PP delay time, the push pulse depletes a fraction of the band-edge ...
To survive in oxic environments, all organisms require mechanisms to degrade toxic reactive oxygen species (ROS). In this Review, James Imlay describes the oxidative stress response ofEscherichia coliand considers the damage caused by ROS and the adaptiv
