The most prevalent reason for IGBT failure in voltage-source inverter (VSI) is thermal stress, which is influenced by the topology and modulation technique adopted. Hence, it is crucial to understand the impact of common sinusoidal pulse width modulation (PWM) strategies on the thermal behavior of VSI and develop improved PWM techniques. This paper presents an alternate hybrid PWM (AHPWM) switching sequence for a single-phase VSI to decrease its thermal stress and prolong its lifetime.

Drought tolerance is a complex phenomenon and multiple gene expression required to maintain the cellular tolerance. Transcription factors (TFs) regulate many functional genes involved in tolerance mechanisms.

We adopted a gene editing approach to create variations in the rice genome by targeting the mutator locus homolog 2 (), a DNA mismatch repair gene. The hypothesis is that disruption of the gene leads to a reduced DNA mismatch repair that creates INDELs, resulting in altered phenotypes.

One of the agricultural challenges today is to develop plants with minimized water utilization and reduced water loss in adverse environmental conditions. Epicuticular waxes play a major role in minimizing water loss.
