A. Reinforcement A reinforcement process is one in which some aspects of the behavior of a system are caused to become more (or less) prominent in the future as a consequence of the application of a "reinforcement operator" Z. This operator is required to affect only those aspects of be-...
EMS practitioners have a legal, moral and ethical obligation to never be in a situation where a patient may die or suffer harm in part because of our own actions or inactions. We all need to work at every level of our respective organizations to prevent this type of tragedy from happening...
Since EMT is an effective way for epithelial cells to acquire the ability to migrate, it is an important way for epithelial cells to acquire mobility. At present, in vivo and in vitro experiments have shown that EMT plays a pivotal role in the metastasis of breast cancer, colon cancer, ...

The apodization function has evolved into a parametrized function whose shape is empirically tuned to enhance the reconstruction and eliminate artifacts. In this sense, the reconstruction has become reliant on the appointed apodization function and is still a heavily debated issue2–9. In our method,...
dog and mouse models are the most commonly used due to their relatively small size and ease of handling. With the exploration and clinical research of fasting treatment strategies to study its impact on chemotherapy and reveal possible side effects, cancer heterogeneity will become a key consideratio...
[4,94], due to the upregulation of the cell cycle inhibitors p16Ink4a, p15Ink4band Arf [95]. These observations are interesting because induction of stemness in tumour cells by DNA damage might have mechanisms in common with how normal cells may be artificially re-programmed to become ...
m also a big advocate of keeping things simple. Those charts that are given to the local venue security with 20-30 different types of credentials that they need to be aware of can become a bit confusing and may ultimately take an 8 hr shift just to figure out. So, I keep the ...
Magnetic Levitation Pen: Not unlike the trains in Japan this pen uses opposing magnetic forces to hover in mid air. For trains, this practically eliminates friction allowing the trains to move very quickly. For pens, it makes for a little added entertain
The diagonalization of this covariance matrix can become an intensive computational problem and so direct iteration or the Lanczos method can be used (as appropriate) to find the eigenvalues θl and the eigenvectors ψl. The expansion of any (new) trajectory vector Xnew may again be found via...
