This work presents two new topological indices, C(u) and C-A(u), that permit their application to organic molecules containing oxygen, nitrogen, sulfur and halogens. These indices are obtained by modifying Schultz molecular ...

Introduction: Although the therapeutic arsenal against ulcerative colitis has greatly expanded (including the revolutionary advent of biologics), there remain patients who are refractory to current medications while the ...

In the last years, the encryption of system structure information with different network topological indices has been a very active field of research. In the present study, we assembled for the first time a complex network ...

Multisource switched-capacitor multilevel inverters are proper topologies when multiple dc sources are available as renewable energy sources. However, these multilevel inverters have the main drawbacks of requiring a large ...
