mutual interference exists, appropriate power control methods need to be implemented to ensure signal to interference plus noise ratio (SINR) is above a certain threshold level for guaranteed quality of service (QoS). Another factor that is influenced due to the presence of D2D pairs and mobile users simultaneously is a delay or the latency, which is an important factor for time-sensitive applications. If both physical layer and latency need to be improved together, the channel state and queuing at

The effect of aging on beta (β1: 12.5–20; β2: 20.5–30 Hz) and gamma (γ1: 30.5–49; γ2: 52–69 Hz) band components of ERP was studied in an auditory discrimination task (low-frequency and high-frequency tone) at frontal, central, parietal and occipital cortical locations at short latency (post-stimulus interval 0–250 ms; putative sensory processing) and long latency (250–600 ms; putative cognitive) periods.

Effect of ethanol on the visual-evoked potential in rat: dynamics of ON and OFF responses

The effect of acute ethanol administration on the flash visual-evoked potential (VEP) was investigated in numerous studies. However, it is still unclear which brain structures are responsible for the differences observed in stimulus onset (ON) and offset (OFF) responses and how these responses are modulated by ethanol. The aim of our study was to investigate the pattern of ON and OFF responses in the visual system, measured as amplitude and latency of each VEP component following acute

of Virtex4 family. Implementation was done for both signed and unsigned number systems, having bit width of operands vary as an exponential function of 􀀂􀀃, where 􀀃=2 to 5. Performance parameters have been calculated in terms of clock frequency, FPGA slice utilization, latency and power consumption. Implementation results indicate that multiplicative based algorithm is superior in terms of latency, while digit recurrence algorithms are consuming low power along-with less area overhead.

nights of extended sleep (>9 h) in the laboratory. The authors reported that auditory vigilance (7–9), complex motor performance (9), sleepiness (10), and mood (7) significantly worsened following extended sleep nights compared to control nights. Further, Roehrs et al. (11) observed that after 1–3 nights of sleep extension, sleep latency tested 2 hours after waking was reduced in a group of alert participants (baseline sleep latency ≤ 16 min). Together, these studies suggest that oversleeping or

of a 120 cm circular pool with a depth of 50 cm filled with about 450 L warm water. A hidden circular platform was placed 1.5 cm below the water surface. Each rat was placed in the maze from four random points of the tank and released to find the hidden platform for 2 min. The time of rat taken to reach the hidden platform (latency) was recorded. If the rat did not reach the platform within 2 min, the rat was gently placed on the platform and left for the 20 s. All rats have received training

Differences in spatio-temporal distribution of the visual P3b event-related potential between young men and women

topography of the P3b potential is consistently determined in both the standard and three-stimulus oddball tasks and in visual modality. Maximum amplitude of this potential, measured on the scalp surface via EEG electrodes, can be observed at parietal regions with a broad peak around 300–450 ms after the onset of the stimulus (Polich, 2007; Volpe et al., 2007; Lafuente et al., 2017). The latency of the P3b potential is shorter over frontal regions and longer over parietal regions (Polich, 2007). The P3b

Optimising data visualisation in the process control and IIoT environments

Introduction Digital transformation creates a need for protocols convergence to ensure cross-system data exchange (Bassi, 2017) and efficient machine-to-machine communication. OPC UA, MQTT, and COAP are some protocols that facilitate cross-system data exchange in the fast-changing data environment. These protocols are functionally achieving common goals in terms of data interoperability but have significant differences in their make in both overheads and data latency. In the IIoT and the 4IR

All subjects underwent polysomnography (PSG) on the two consecutive nights. The data from the second night was analysed. The slow wave activity (SWA, 1–4 Hz) was calculated for the three consecutive sleep cycles, and topographic delta power maps were plotted. In contrast to narcoleptics, psychiatric hypersomniacs had undisturbed nocturnal sleep, high sleep

SOCIAL POPULARITY BASED ROUTING IN DELAY TOLERANT NETWORKS

Due to node’s mobility, Delay Tolerant Networks (DTNs) feature the nonexistence of end-to-end path between source and destination, frequent topology partitions and extremely high delivery latency, thus posing great challenges to successful message transmission. To improve routing performance and provide high quality communication service, nodes’ social characteristics are exploited to routing design recently. Hence, a social popularity based routing algorithm is proposed, named SPBR which takes

These passive trials required no behavioural response and were administered to measure the complete set of OSP (i.e., the rate of rise, amplitude and peak latency). OSPs showed a faster rate of rise for auditory stimuli compared to visual or somatosensory stimuli. Auditory stimuli also produced a shorter time to peak and
