The rice blast fungus, Magnaporthe grisea, generates enormous turgor pressure within a specialized cell called the appressorium to breach the surface of host plant cells. Here, we show that a mitogen-activated protein kinase, Mps1, is essential for appressorium penetration. Mps1 is 85% similar to yeast Slt2 mitogen-activated protein kinase and can rescue the thermosensitive growth of slt2 null ...

CONTEXT Intraductal papillary mucinous neoplasm (IPMN) of the pancreas occasionally penetrates to others organs. We present a case of IPMN penetrating to the stomach and the common bile duct. CASE REPORT A 75-year-old man was admitted to the hospital because of epigastric pain. Computed tomography (CT) showed a papillary tumor protruding into the markedly dilated main pancreatic duct and sple...

A specific rock energy profile can be generated for every hole, and thus a drilling site can be mapped for this index. A special data acquisition system was devel...

Three antimicrobial peptides derived from bovine milk proteins were examined with regard to penetration into insoluble monolayers formed with 1,2-dipalmitoyl-sn-glycero-3-phosphocholine (DPPC) or 1,2-dipalmitoyl-sn-glycero-3-phospho-rac-(1-glycerol) sodium salt (DPPG). Effects on surface pressure (Π) and electric surface potential (ΔV) were measured, Π with a platinum Wilhelmy plate and ΔV with...

The rice blast fungus Magnaporthe grisea infects its host by forming a specialized infection structure, the appressorium, on the plant leaf. The enormous turgor pressure generated within the appressorium drives the emerging penetration peg forcefully through the plant cuticle. Hitherto, the involvement of cutinase(s) in this process has remained unproven. We identified a specific M. grisea cuti...

We study the lags with which new technologies are adopted across countries, and their penetration rates once they are adopted. Using data from the last two centuries, we estimate both the extensive and the intensive margins of technology adoption. We document two new facts: there has been convergence in adoption lags between rich and poor countries, while there has been divergence in penetratio...

Pentesting is becoming an important activity even for smaller companies. One of the most important economic pressures is the cost of such tests. In order to automate pentests, tools such as Metasploit can be used. Post-exploitation activities can, however, not be automated easily. Our contribution is to extend Meterpreter-scripts so that postexploitation can be scripted. Moreover, using a multi...

When connected in small amounts, the impact of distributed generation (DG) on distribution system stability will be negligible. However, if its penetration level becomes higher, distributed generation may start to influence the dynamic behavior of the system as a whole. This paper presents a mathematical representation of a solid oxide fuel cell plant that is suitable for use in distribution sy...
