A possible role for intrinsic calcium buffers in the long- term adaptation of crayfish neurons
… mechanisms and indicate "long-term adaptation" (LTA) of nerve terminals. Previous experiments have shown that LTA requires extracellular calcium and protein synthesis (eg. Hong and Lnenicka, Soc. Neurosci. Abstr. 17:1322) and appears to involve communication between the cell body and the nerve …

Microwave synthesis and occlusion reactions of zeolites
… is dedicated to the synthesis of zeolites A (LTA), X (FAU), Y, (FAU) and rho (RHO) in a microwave oven. Results have demonstrated that when zeolitic gels are heated in a microwave oven they yield zeolite crystals far quicker than when heated in a conventional oven. This is in part a …

Automated seismic event location by waveform coherence analysis
… on the Short-Term-Average/Long-Term-Average (STA/LTA) traces at different stations as observed data. I used the STA/LTA of several characteristic functions in order to increase the sensitiveness to the P wave and the S waves. For the P phases we use the STA/LTA traces of the vertical energy …

Automatic P-wave Picking of Microseismic Events in Underground Mines
… average to long-term average ratio detector (STA/LTA), the characteristic function detector (CF), and the autoregressive modelling detector (ARfpe). Several versions of each algorithm were implemented, and the most promising versions were tested on the full dataset of microseismic events. The …

Rational Development of New Inhibitors of Lipoteichoic Acid Synthase
… targets. Recently, the lipoteichoic acid (LTA) biosynthesis pathway has emerged as a potential anti-bacterial target. LTA is an anionic polymer found on the cell envelope of Gram-positive bacteria. It comprises of repeating units of glycerol-phosphate (GroP) and is important for bacterial …

The Role of Low Tone Average in the Diagnosis of Meniere's Disease
… to create two new measures: 1) Low tone average (LTA), which was an average of 250 Hz, 500 Hz, and 1000 Hz; and 2) Meniere’s Ratio (MR), which was a ratio of LTA to pure tone average. Ideally the LTA would include 125 Hz to emphasize the low-frequency loss: however, 125 Hz is not routinely tested …
