Synergy and Group Size in Microbial Cooperation
No full textMicrobes produce many molecules that are important for their growth and development, and the exploitation of these secretions by nonproducers has recently become an important paradigm in microbial social evolution. Although the production of these public-goods molecules has been studied intensely, little is known of how the benefits accrued and the costs incurred depend on the quantity of public-goods molecules produced. We focus here on the relationship between the shape of the benefit curve and cellular density, using a model assuming three types of benefit functions: diminishing, accelerating, and sigmoidal (accelerating and then diminishing). We classify the latter two as being synergistic and argue that sigmoidal curves are common in microbial systems. Synergistic benefit curves interact with group sizes to give very different expected evolutionary dynamics. In particular, we show that whether and to what extent microbes evolve to produce public goods depends strongly on group size. We show that synergy can create an "evolutionary trap" that can stymie the establishment and maintenance of cooperation. By allowing density-dependent regulation of production (quorum sensing), we show how this trap may be avoided. We discuss the implications of our results on experimental design.</p

A TCAD Simulation Study on the Short-circuit Performance of 650V P-pillar Offset Super-junction MOSFET
No full textThe limitation of Silicon based power MOSFET was broken by the super-junction (SJ) structure, which can provide lower specific on-resistance and higher breakdown voltage compared with the conventional power MOSFET structure. Multi-epitaxial and multi-ion-implant technology, as a mature manufacturing process of the SJ structure, has been widely used in the field of SJ-MOSFET. Therefore, this process is applied to construct the cell structure of 650V SJ-MOSFET in our study. Based on practical application, high current caused by unexpected short circuit will induce an increasing of the internal temperature of SJ-MOSFET, which leads to an irreversible damage in the SJ-MOSFET devices. However, the short-circuit robustness of SJ-MOSFET is still unstable, and the structure needs to be further improved. In our study, the electrical performance of a 650V SJ-MOSFET with offset P-pillar is theoretically investigated by means of technology computer aided design (TCAD) when the SJ-MOSFET is short circuited. The results clearly show that the optimized SJ-MOSFET can withstand the source-drain voltage of 400V for at least 10 μs in the case of the short-circuit. The thermal distribution and peak temperature of the cell structure of SJ-MOSFET are also simulated to assist in the analysis of the short circuit capable of the device. In addition, the hole current density distribution of two SJ-MOSFETs is considered to gain insight into the effect of P-pillar parameters on the short-circuit robustness. The result represents that the structure with offset P-pillar can effectively improve the short-circuit capability.Green Open Access added to TU Delft Institutional Repository 'You share, we take care!' - Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public.Bio-ElectronicsElectronic Components, Technology and Material
