Cerebellar climbing fibers (CFs) provide powerful excitatory input to Purkinje cells (PCs), which represent the sole output of the cerebellar cortex. Recent discoveries suggest that CFs have information-rich signaling properties important for cerebellar function, beyond eliciting the well known all-or-none PC complex spike. CF morphology has not been quantitatively analyzed at the same level of...

Six Iranian accessions of Cucumis melo, including Inodorus, Cantalupensis, and Dudaim groups, were planted and then harvested at two harvesting stages including 21 and 28 days after anthesis for Dudaim group and 28 and 38 days after anthesis for Inodorus and Cantalupensis groups. At the time of harvest, we measured some quality parameters and appearance indices of fruits, such as the number of ...

The mechanics and dynamics of the helix hand reversal (perversion) exhibited by the tendrils of climbing plants is investigated. The tendrils are modeled as thin elastic rods with intrinsic curvature and a linear and nonlinear stability analysis is performed. This system provides an example of curvature driven morphogenesis

Arcing was ignited on deformed tungsten (W) surfaces, where W fuzz and/or nano-tendril bundles (NTBs) were grown, by steady state helium (He) plasma exposures with impurity gas seeding. At the same sample potential of −250 V, presence NTBs enhanced frequency arc ignition, whereas no ignition appeared typical surfaces without NTBs. After a series ignitions surface NTBs, aspect ratio decreased, i...
