Autoantibodies against phosphatidylserine and DNA during canine Dirofilaria immitis infection.

Heartworm infection caused by Dirofilaria immitis induces a devastating disease that greatly affects the global canine population.

Arithmetic optimization based MPPT for photovoltaic systems operating under nonuniform situations.

Photovoltaic (PV) modules may encounter nonuniform situations that reduce their useable power volume, causing ineffective maximum power point tracking (MPPT).
