During visual stimulation, neurons in the lateral geniculate nucleus (LGN) of the thalamus exhibit two distinct response modes, tonic and burst. There is mounting evidence that each mode serves a distinct function: burst firing signals the appearance of a salient stimulus (detection), while tonic firing relays detailed stimulus features (transmission). Recent studies comparing the responses of ...

In the study of LF noise in MOSFETS, it has become clear that Random Telegraph Signals (RTS) are dominant. When a MOSFET is subjected to large-signal excitation, the RTS noise is influenced. In this paper, we present different visualizations of the transient behaviour of the RTS. Keywords— MOSFET, Random Telegraph Signal, Large Signal Excitation, LF Noise.

Fast burst synchronization is an important requirement in asynchronous communication networks, where devices transmit short data packets in an unscheduled fashion. Such a synchronization is typically achieved by means of a preamble sent in front of the data packet. In this paper, we study fast burst synchronization for power line communication (PLC) systems operating below 500 kHz and transmitt...

In this paper influence of burst packet loss on the quality of telephony speech signal in the packet network of Electric Power Utility (EPU) is calculated. Due to transients, the burst packet loss in EPU network is more probable than random packet loss. We can calculate the impairment factor in two ways: as the mean value of impairments in all nodes, or as the impairment for the mean value of b...

In this paper, we show the benefit of an integrated analysis of performance and technology, as both signal degradation and burst losses limit the effective throughput of optical burst switching nodes. The investigation covers the Tune-andSelect (TAS) base architecture as well as extensions with dedicated and shared FDL buffers. First, we describe these node architectures and the OBS reservation...

ct In burst-mode data transmission used in GSM and IS2. INITIAL PARAMETER ESTIMATIONS FOR BURST Abstra 136, rapid acquisition of the symbol timing and the carrier phase from the observation of a short signal-segment is essential. Feedforward timing recovery is well suited for such transmissions due to its rapid acquisition characteristics. For personal mobile communications where low complexity...

The use of vetoes generated from auxiliary channels suppresses most of the high amplitude noise triggers that impair gravitational wave (GW) burst and binary inspiral searches. During Virgo’s first scientific run (VSR1), many of the remaining loud burst and inspiral Virgo triggers were observed with nearly equal significance in both the in-phase (ACp) and quadrature (ACq) interferometer output ...

We have developed a method ’time-frequency (TF) clustering’ to find the burst gravitational waves for TAMA data analysis. TF clustering method on sonogram (spectrogram) shows some characteristics of short duration signal. Using parameters which represent the cluster shape, we can efficiently identify some predicted gravitational wave forms[1][2] and can exclude typical unstable spike like noise...

The bi-level input processing model posits two levels of speech sound processing. In this model, context-bound allophones are encoded separately at a lower level of processing. If this is the case, second language learners should exhibit some facilitation effect when perceiving non-native phonemes that are used as context-bound allophones in their first language. Using a cue-weighting design, t...

The sampling rate in most hard disk drives (HDDs) is limited by the number of servo burst sectors that have prewritten position error signal (PES) data and by the spinning speed of the HDD. This paper presents an algorithm that can generate estimates of the PES during read at high sampling rates by processing the dedicated servo burst measurements and the mean square error (MSE) path metric dat...
