We present the first direct calculation on gravitational form factors (GFFs) of $N \rightarrow \Delta$ transition using an analytic method, QCD light-cone sum rules. The matrix element quark part energy momentum tensor current sandwiched between nucleon and $\Delta$ states are parameterized in terms five independent conserved four non-conserved GFFs, for which we use distribution amplitudes (DA...

effects of catechin for preventing black spots forming in whiteleg shrimp (litopenaeus vannamei) were evaluated. for processing whole shrimp, catechin was used at a concentration of 0.2 and 0.3 % for 15 minutes. sodium metabisulfite was used at a concentration of 3 % for 10 minutes as control samples. without antioxidant shrimp were used as control samples too. treatments quality was evaluated ...

The tamoxifen-inducible Cre-loxP system is widely used to overcome gene targeting pre-adult lethality, to modify a specific cell population at desired time-points, and to visualize and trace cells in fate-mapping studies. In this study we focused on tamoxifen degradation kinetics, because for all genetic fate-mapping studies, the period during which tamoxifen or its metabolites remain active in...
