Synapse remodeling, which involves changes in the synaptic structure and their molecular composition, is required for the maturation and refinement of neural circuits. Although synapse remodeling is known to be tightly dependent on the assembly of local actin cytoskeleton, how actin directs the structural changes of synapse and targeting of synaptic(More)
during spatial trajectories fired in a time-compressed sequence that occurred over one theta cycle (~120 ms). These theta sequences, which occurred both in the maze and on the wheel, were abolished by medial septal inac-tivation. What is the relationship between these theta sequences and episodic or spatial trajectories? To examine this question, the(More)
In this paper, we provide theoretical and simulation-based study of the delivery delay performance of a number of existing throughput-optimal coding schemes and use the results to design a new dynamic rate adaptation scheme that achieves improved overall throughput-delay performance. Under a baseline rate control scheme, the receivers' delay performance is(More)
In this paper we study in-order packet delivery delay of two recently proposed network coded transmission schemes with applications in wireless broadcast. Unlike previous works where asymptotic behaviour of decoding or delivery delay was presented, we provide a general analysis of the three conditions under which in-order packet delivery is possible at a(More)
In this paper, we demonstrate a network coded transmission scheme that allows the implementation of multicast video on demand using a single server channel. A receiver is permitted to join the broadcast at any time, where after an initial startup delay, it is able to deliver packets at its channel rate. This transmission scheme is the first to allow(More)
In a single hop broadcast packet erasure network, we demonstrate that it is possible to provide multirate packet delivery outside of what is given by the network min-cut. This is achieved by using a deterministic non-block-based network coding scheme, which allows us to sidestep some of the limitations put in place by the block coding model used to(More)
—We introduce a homogeneous r-regular network model for a peer-to-peer (P2P) video broadcast network. Such networks are simple to construct and allow the implementation of fairness strategies. We use our model to show why the greedy and rarest first push-based strategies give the suboptimal performance often observed in the literature. We propose a novel(More)
