The authors obtain necessary and sufficient conditions for the existence of oscillatory solutions with a specified asymptotic behavior of solutions to a nonlinear neutral differential equation with distributed delay of third order. We give new theorems which ensure that every solution to be either oscillatory or converges to zero asymptotically. Examples dwelling upon the importance of applicab...

Burrowing bugs are distinctive, beetle-like insects of the pentatomoid family Cydnidae, noteworthy for their morphological specializations digging and a hemiedaphic life history. However, less is known about biological significance early origin soil dwelling. Direct fossil evidence illuminating evolutionary history dwelling in cydnids extremely rare. In this study, we report four new species bu...

Community dwelling elderly people with a history of falls are likely to sustain subsequent falls and injurious falls. Elderly people who have had a previous fall with a fracture are at an increased risk of major injurious fall. However, the recurrence of major fall injuries other than fractures remains unknown. We conducted a prospective population-based cohort study among home dwelling elderly...
