In sensory neurons (SNs) of adult Aplysia, serotonin (5-HT)-induced spike broadening has long been implicated as important for synaptic facilitation [spike duration-dependent (SDD) facilitation], particularly at nondepressed synapses. At depressed synapses, spike broadening has less impact on synaptic facilitation; under these conditions, 5-HT induces a spike duration-independent (SDI) form of ...

the neighborhood is a major factor in urbanism where habitation is characterized.in iranian traditional cities, the concept of neighborhood demonstrates the values of well-being, identity and sociability. neighborhoods can be approached into the following ways: external view that includes official boundaries, issues related to urban development and urban management. internal view that is based ...

in this paper, the concept of {sl local base with  stratifiedstructure} in $i$-topological vector spaces is introduced. weprove that every $i$-topological vector space has a balanced localbase with stratified structure. furthermore, a newcharacterization of $i$-topological vector spaces by means of thelocal base with stratified structure is given.

Collinear facilitation of contrast detection of achromatic stimuli has been studied over the past decade by different groups. We measured collinear facilitation of chromatic contrast detection under equal-luminance (photometric quantity) and under isoluminance (minimum motion technique) conditions, as two different controls. The facilitation was tested for chromatic contrast detection of a fove...

different methods arising from scientific investigation for removing noise from chaotic signals have been introduced and one of their best is local projection approach. the local projection approach projects the chaotic data in the neighborhood onto the hyper-plane. selection of neighborhood radius has a direct impact on its performance. a noticeable feature associated with chaotic trajectories...

Although facilitation and leadership behaviors are thought to be critical to the success of virtual teams, little research has been done to examine the impact of facilitation behaviors on virtual teams. In order to fill this knowledge gap, this study empirically examines the impact of external facilitation behaviors on virtual team interactions and outcomes. Contrary to common belief, our findi...
