The plant mitochondrial genome is retained in a multipartite structure that arises by a process of repeat-mediated homologous recombination. Low-frequency ectopic recombination also occurs, often producing sequence chimeras, aberrant ORFs, and novel subgenomic DNA molecules. This genomic plasticity may distinguish the plant mitochondrion from mammalian and fungal types. In plants, relative copy...

Audio time stretching and pitch shifting are operations that all major commercial and/or open source Digital Audio Workstations, DJ Mixing Software and Live Coding Suites offer. These operations allow users to change the duration of audio files while maintaining the pitch and vice-versa. Such operations enable DJs to speed up or slow down songs in order to mix them by aligning the beats. Unfort...

In audio engineering, Pitch shifting is a term to describe the process of changing the pitch of an audio signal (which is related to the logarithm of the frequency), but opposite to resampling, pitch shifting retains the duration of the original signal. This process is very useful for example in correcting slightly out-of-tune singers or instruments. The dual problem is changing the signal dura...

We study extended oscillatory systems that respond to uniform periodic forcing at one quarter of the forcing frequency. We find a new type of front instability where a stationary front shifting the oscillation phase by π decomposes into a pair of traveling fronts each shifting the phase by π/2. The instability designates a transition from standing two-phase patterns, involving alternating domai...

The paper presents an improvement of the n-shifting technique to identify frequency response industrial process using a fully asymmetric and delaying relay. approach allows...

Dynamic Ratcheting (DR) is a nonlinear dynamic phenomenon occurring in hysteretic damping systems. It means the structural plastic deformation increases asymmetrically in successive cycles under an earthquake excitation. Although it is generally recognized that DR is closely related to the frequency contents of an earthquake excitation applied to thestructure, no targeted analysis has bee...
