Auditory brain-stem response (ABR) was measured in 40 patients (80 ears) with confirmed hydrocephalus. Eighty-eight percent of these patients showed some form of ABR abnormality. Responses indicative of brain-stem dysfunction consisted of prolonged I-V interwave latency (38%), reduced V/I amplitude ratio (33%), and abnormalities in wave-shape of components III (27%) and V (53%). In addition, 70...

The rate control mechanism for Available Bit Rate ABR tra c as de ned by the ATM Forum does not distinguish between di erent types of ABR connections However since ABR tra c may result from a heterogeneous set of applications there is an apparent need for a ow control scheme that can distinguish between and give di erential treatment to di erent classes of ABR connections In this study a multi ...

The Available Bit Rate (ABR) service has been shown to enable persistent, greedy data sources to e ciently utilize ATM network resources. However, the throughput for bursty TCP over ABR data tra c in the presence of interfering tra c may not be as good as for persistent ABR sources without interfering tra c. This paper shows that in a comparison of rate based ABR schemes (EPRCA and ERICA) and a...

BACKGROUND Recent studies have shown effective clinical results after arthroscopic Bankart repair (ABR) but have shown several risk factors for re-dislocation after surgery. We evaluated whether patients are at a risk for re-dislocation during the first year after ABR, examined the recurrence rate after ABR, and sought to identify new risk factors. METHODS We performed ABR using bioabsorbable...

In mice, the auditory brainstem response (ABR) is frequently used to assess hearing status in transgenic hearing models. The diagnostic value of the ABR depends on knowledge about the anatomical sources of its characteristic waves. Here, we studied the contribution of the inferior colliculus (IC) to the click-evoked scalp ABR in mice. We demonstrate a non-invasive correlate of the IC response t...

Previous studies have demonstrated an increase in the arterial baroreflex (ABR) control of muscle sympathetic nerve activity (MSNA) during isolated activation of the muscle metaboreflex with postexercise muscle ischemia (PEMI). However, the increased ABR-MSNA control does not appear to manifest in an enhancement in the ABR control of arterial blood pressure (BP), suggesting alterations in the t...

In this paper we evaluate various aspects of the ABR flow control schemes using three different evaluation techniques: analysis, simulation and experiments. A discrete-time Markov model alows the evaluation of the influence of different system parameters (distance between source and switch, burstiness of CBR/VBR traffic, time in between computation of Allowed Cell Rate and burstiness of ABR tra...

1 A comparison of ABR and UBR to support TCP tra c Sam Manthorpe and Jean-Yves Le Boudec Abstract|This paper compares the performance of ABR and UBR for providing high-speed network interconnection services for TCP tra c. We test the hypothesis that UBR with adequate bu ering in the ATM switches results in better overall goodput for TCP tra c than explicit rate ABR for LAN interconnection. This...

The auditory brainstem response (ABR), a measure of neural synchrony, was used to estimate auditory sensitivity in the eastern screech owl (Megascops asio). The typical screech owl ABR waveform showed two to three prominent peaks occurring within 5 ms of stimulus onset. As sound pressure levels increased, the ABR peak amplitude increased and latency decreased. With an increasing stimulus presen...
