Substantial exposure to Borrelia miyamotoi occurs through bites from Ixodes ricinus ticks in the Netherlands, which also transmit Borrelia burgdorferi sensu lato and Anaplasma phagocytophilum. Direct evidence for B. miyamotoi infection in European populations is scarce. A flu-like illness with high fever, resembling human granulocytic anaplasmosis, has been(More)
This note is focused on a bounded control problem with boundary conditions. The control domain need not be convex. First-order necessary condition for optimality is obtained in the customary form of the maximum principle, and second-order necessary condition for optimality of singular controls is derived on the basis of second-order increment formula using(More)
Dengue is an infection transmitted by mosquitoes and is present in all tropical and subtropical regions of the planet. In recent years, the transmission of the disease has increased, predominantly in urban and semi-urban areas, and has become an important public health problem. The National Health Institute (Instituto Nacional de Salud-INS) determined Cali(More)
The aim of the present work was to study the anatomical characteristics of the stellate ganglion (SG) and the morphometric properties of its neurons in rats of different age groups (neonatal and 10, 20, 30, 60, and 180 days) using anatomical and histological methods. The results identified three variants of the origins of branches from the medial border of(More)
This work examines both positive and negative impacts that economic growth may have on the ecological dynamics and stability of a single biological species. Local extinction of the species may force the social planner to implement defensive expenditures aimed at conservation of the species population by means of habitat protection. The latter may lead to an(More)
The background electrical activity of neurons in the cranial cervical ganglion was studied in neonatal rats and in animals aged 10, 20, and 30 days and two and six months. All age groups showed a predominance of neurons with irregular activity and fewer neurons with spikes synchronized with respiration. In neonates and 10-day-old animals, neurons in the(More)
