Abstract: Systems, apparatuses, and methods for placing cells in an integrated circuit are described. In various embodiments, an integrated circuit is divided into many partitions. In a first set of partitions susceptible to transistor latch-up, the many transistor gate stripes are connected to one of the power rails rather than left floating. The lengths of the transistor gate stripes are shortened for well tap cells in the first partition, but increased in a second partition susceptible for poor signal integrity. One or more implant layers are formed underneath the transistor gate stripes in each of the first and second partitions to adjust an amount of protection against transistor latch-up and poor signal integrity. An electrostatic discharge transistor is included with at least one source region of multiple source regions formed in a well with a same doping polarity as the at least one source region.

Abstract: Early vascular cells (EVCs), including endothelial cells and pericytes, are generated from hiPSCs. Unlike the isolated endothelial progenitor cells, the differentiated ECs mature and are functional.

Abstract: A water level controller for a hydroponic system includes a float shifting upward and downward with the culture solution, a first magnetic attraction element and an inlet valve for feeding in the culture solution. The float includes a seal and a second magnetic attraction element. The seal closes the inlet valve to stop feeding in water when the float ascends to a high water level, and moves way from the inlet valve to start feeding in water at a low water level. The second magnetic attraction element attracts the first magnetic attraction element to keep the seal closing the inlet valve at the high water level and to keep the seal moving away from the inlet valve at the low water level, until the buoyancy of the float is larger than the magnetic attraction between the second and the first magnetic attraction element thereby causing escape from each other.
