Plant mitochondria are proposed to act as signaling organelles in the orchestration of defense responses to biotic stress and acclimation responses to abiotic stress. However, the primary signal(s) being generated by mitochondria and then interpreted by the cell are largely unknown. Recently, we showed that mitochondria generate a sustained burst of superoxide (O 2(-)) during particular plant-p...

Bursts are produced by closing the oral tract at a place of articulation and suddenly releasing the acoustic energy built-up behind the closure in the tract. The release of energy is an impulselike behavior, and it is followed by a short duration of frication. The burst release is short and mostly weak in nature (compared to sonorant sounds), thus making it difficult to detect its presence in c...

The brain is a complex adaptive system, processing information from the internal and external environment. Information is transmitted within the nervous system in at least 2 separate firing patterns, tonic and burst firing. Burst firing consists of closely spaced spikes at high frequency (eg 500 Hz) followed by quiescent periods. It has been proposed that burst firing is a signal detector, a ki...

We demonstrate burst-mode operation of a polarization-maintaining Yb-doped fiber amplifier. Groups of pulses with a temporal spacing of 10 ns and 1 kHz overall repetition rate are amplified to an average pulse energy of ∼20 μJ and total burst energy of 0.25 mJ. The pulses are externally compressed to ∼400 fs. The amplifier is synchronously pulsed-pumped to minimize amplified spontaneous emissio...

This paper we proposed advanced burst mode control technique to reduce the standby power consumption of the switch mode power supply (SMPS). To reduce the standby power consumption, most of the converter use burst mode or skip mode control technique. However Conventional standby mode control techniques have some problems such as audible noise and poor regulation. In proposed techniques, basical...

This paper proposes a carrier phase estimation of a power efficient APSK signal with a honeycombed constellation at a receiver in point-to-multi-point fixed wireless access systems using quasimillimeter frequency band. The signal has a lower amplitude level of a maximum signal vector than a conventional QAM signal. The signal also has a lower average output power. A reference carrier phase of t...
