Toxoplasma gondii and Rickettsia spp. in ticks collected from migratory birds in the Republic of Korea

open access: yesScientific Reports, 2022
Migratory birds disperse ticks and associated tick-borne pathogens along their migratory routes. Four selected pathogens of medical importance (Coxiella burnetii, Rickettsia spp., Francisella tularensis, and Toxoplasma gondii) were targeted for detection

Silicon Nitride Resistive Memories

open access: yesAdvanced Electronic Materials, EarlyView.
Amorphous SiNx is an attractive resistance switching material for ReRAM applications due to its physicochemical properties, such as humidity resistance, low oxygen diffusivity, and is used as a metal diffusion blocker. By modifying the ratio between N and Si atoms, the microstructure of the SiNx is affected, rendering it possible to change the ...

Radar And Visual Observations Of Autumnal (Southward) Shorebird Migration On Guam [PDF]

open access: yes, 1988
Several species of shorebirds migrate between eastern Asia and the southern Pacific islands, Australia, and New Zealand. Observations made from Guam (13°25′N, 144°45′E) during autumn 1983 indicate that a significant number of birds take a direct route ...

Evidence for West Nile Virus and Usutu Virus Infections in Wild and Resident Birds in Germany, 2017 and 2018 [PDF]

open access: yes, 2019
Wild birds play an important role as reservoir hosts and vectors for zoonotic arboviruses and foster their spread. Usutu virus (USUV) has been circulating endemically in Germany since 2011, while West Nile virus (WNV) was first diagnosed in several bird ...

Comparison of the Survival Rates between Migratory and Resident Birds [PDF]

open access: yes, 2019
Knowledge of survival rates is critical for understanding population change for any species. Migratory species may have lower survival rates than resident species due to the physiological stress of migration and movement through unfamiliar habitat.
