Analyzing Ultrastructural characteristics of Post-synaptic targets of pre-identified Presynaptic Boutons in layer 3 and layer 4 of the Ferret Primary Visual cortex
… characterized pre-synaptic elements in layers 3 and 4 of the primary visual cortex (PVC). We are aiming to quantify a range of values for synaptic element morphologies as well as to correlate pre- and post-synaptic elements to find a set of rules that is prevalent in the visual cortex …

Cellular and Synaptic Morphology of Golgi -Impregnated Cortical Neurons in Patients With Schizophrenia
… alterations differ across brain region, cortical layer, cell type, or antipsychotic treatments. Formalin-fixed tissue blocks from frontopolar cortex, Area 10, and primary visual cortex, Area 17, were acquired from a pool of 16 subjects with chronic schizophrenia and 22 normal comparison subjects. …

Ultrastructural correlates of axons and synapses belonging to different circuits in ferret primary visual cortex
… was to determine differences in distinctive layers of mammalian primary visual cortex through analysis of their ultrastructural characteristics. Characterizing brain circuitry using 3-dimensional reconstruction of electron microscopy images, and subsequent ultrastructural analysis of axonal …

Providing guaranteed QoS in the hose-modeled VPN
… VPN service is provided by implementing layer 2 technologies, either Frame Relay (FR) or Asynchronous Transfer Mode (ATM). With FR or ATM, virtual circuits are created before data delivery. Since the bandwidth and buffers are reserved, the QoS requirements can be naturally guaranteed. In …

Design and Evaluation of Multi-Channel Multi-Hop Wireless Networks
… multi-hop network, with the focus on layer-2 and layer-3 protocols. Based on the observations, we develop medium access control (MAC) and routing protocols that can utilize multiple channels with a single interface. Finally, we evaluate the multi-channel protocols through simulation …

Adaptive watermarking algorithms for MP3 compressed audio signals
MPEG-1 Layer 3, known as MP3, has generated a significant popularity for distributing digital music over the Internet. MP3 compresses digital music with high ratio while keeping high sound quality. However, copyright issue is raised because of illegal copy, redistribution and various malicious …

Convective heat transfer model for determining quench recovery of high temperature superconducting YBCO in liquid nitrogen
… include: 1) presence or absence of copper layer incorporated into the sample; 2) thickness of copper layer; 3) nominal operating current before and after the application of a current pulse; 4) pulse current amplitude, and 5) pulse current duration. Recorded signals were sample voltages, …

Dual Layer Scale Free Network Topology Synthesis
… we focus on the multi-access links, i.e., link-layer networks that form the same collision domain between attached devices, as they should be considered to reflect the single hop connectivity of the devices attached to a subnetwork. While consideration of the multi-access links helps to better …

OLSR-based network discovery in situational awareness system for tactical MANETs
… provide coarse localization information based on layer-3 connectivity information and a few anchor nodes or landmarks, and without using traditional methods such as signal strength, Time of Arrival (ToA) or distance information. We propose a localization algorithm based on a Force-directed method …

Mobility modeling and topology prediction in cognitive mobile networks
… The localization information was gathered from layer-3 connectivity, utilizing anchor nodes that are equipped with GPS and other non-GPS nodes instead of using traditional methods that include received signal strength, time of arrival and angle of arrival. The approximate location information of …

The Impact of Rogue Nodes on the Dependability of Opportunistic Networks
… simulator developed in Java, simulating the layer 3 of the OSI model. The Rogue behavior is implemented in the simulator to observe the effect of rogue nodes. Finally we extracted the desired dataset to measure the latency by carefully simulating the intended behavior, keeping rest of the …
