pain is one of the most important and sometimes difficult problems, that patients and physicians are encountered. it may be clinically acute or chronic, acute pain has usually definite cause and favourable response to treatment. on the other hand there are difficulties in diagnosis and management of chronic pain. peripheral and cranial nerves convey pain impulses toward central nervous system, ...

Differentiation of human-induced pluripotent stem cells (hiPSCs) toward kidney organoids is known to suffer from batch-to-batch differences, off-target populations, and skewered cellular compositions. Application synthetic hydrogels as a tool for hiPSC-differentiation may provide additional control over this variable process. This review discusses important material properties that affect organ...

Single-source binary hybrid multilevel inverters with cascaded transformers have a bulky transformer connected to their main H-bridge cells in each phase. This bulky transformer has been eliminated in this work without any effect on operation and modulation strategies. The proposed topology has significant advantages from view point of dimensions and number of transformers, design of transforme...
