It is an important task in neuroscience to find general principles that relate neural codes to the structure of the signals they encode. The structure of sensory signals can be described in many ways, but one important categorization distinguishes continuous from transient signals. We used the communication signals of the weakly electric fish to reveal how transient signals (chirps) can be easi...

The leukocyte response integrin (LRI) is a phagocyte integrin which recognizes the basement membrane protein entactin and the synthetic peptide Lys-Gly-Ala-Gly-Asp-Val (KGAGDV). The function of LRI is intimately associated with that of a distinct membrane protein, integrin-associated protein (IAP), as antibodies which recognizes IAP can inhibit all known functions of LRI. When adherent to surfa...

We demonstrate a 100-Gb/s real-time coherent burst-mode receiver for the first time, based on 32-GSa/s low-profile ADCs. A particularly designed DSP architecture was implemented for rapid burst data recovery, FTL transience compensation and effective channel equalization. Introduction With the rapidly increasing bandwidth demand in recent years, the cost and power consumption for transceiving a...

Abnormal sound detection using a one-class support vector machine (OCSVM) and principal component analysis (PCA) is proposed aiming to stable objective inspection without skilled plant inspectors. For measurement of acoustic signals, we developed compact microphone unit that can work in detection, signal transmission, power supply, wirelessly. Six parameters were extracted as features from filt...

l.n this paper, the performances of constant falsealarm rate (CFAR) burst detection schemes are analyzed and compared for a communication system which employs constant modulus modulation format and a typical time division multiple access (TDMA) protocol, The burst detection probabilities are derived to incorporate the received signal quality measure which can be expressed as a function of cross...

The present experiments examine the effect of a weak 40-ms tone burst cue on the detection of a closely following 40-ms signal at the same frequency. Detection becomes more difficult as the temporal separation onset to onset between them shortens from around 300 ms to under 52 ms. The threshold increase or proximal interference is similar whether signal frequency is constant from trial to trial...

There is general agreement that saccades are guided to their targets by means of a motor error signal, which is produced by a local feedback circuit that calculates the difference between desired saccadic amplitude and an internal copy of actual saccadic amplitude. Although the superior colliculus (SC) is thought to provide the desired saccadic amplitude signal, it is unclear whether the SC res...

the paper presents lower and upper bounds on the number of parity check digits required for a linear code that detects solid bursts of length $b$ or less and simultaneously any $e$ or less random errors. an example of such a code is also provided. further, codes capable of detecting and simultaneously correcting such errors have also been dealt with.

background adenylate cyclase toxin (cyaa) is an important virulence factor of bordetella pertussis, the causative agent of whooping cough, and a potential component of acellular pertussis vaccine. objectives in the present study the impact of invasive cyaa on oxidative activities of phagocytes was compared with the other form of this molecule to investigate the activity of different parts of mo...

We present the results of the spectral analysis of a sample of short bright γ–ray bursts (GRB) detected by BATSE and compare them with the average and time resolved spectral properties of long bright bursts. While the spectral parameters of short GRBs confirm, as expected from previous works based on the hardness ratio, that they are harder than long events, we find that this difference is main...
