There are several different types of research designs researchers can use to approach their research questions. Discover how a researcher can choose the right type of design depending on their objectives, learn the time-related differences between cross-sectional and longitudinal designs, explore differen...
To protect the integrity of organisms and cells, the immune system evolved into one of the most complex networks. It is particularly effective in defense against pathogens, however, it often fails to mount equally potent responses against cancer, as tumors developed a multitude of ways to evade ...

The vital issues of rechargeable lithium batteries widely used for everyday energy storage is being studied by many researchers to enhance the battery performance and safety. Graphene as well as cheaper and more accessible reduced graphene oxide (rGO) are known for high electrical conductivity, specif...
The early research on the theory of biregular functions originates from Brakex and Pincket (see [5,6,7,8,9]). In [7], the Cauchy integral formula for regular functions is extended to the case of biregular functions. Furthermore, applying the Cauchy formula, the Taylor series expansion ...
