and ciliary action helps expell bacteria and other particulate material. Other examples of nonspecific host defense mechanisms include thecoughand gag reflexes,gastric acidity,intestinal motility, free drainage of body cavities ranging from theparanasal sinusesto thebladder, and intact lymphatic and circula...

It is well established that cells have evolved effective defense mechanisms against cellular transformation. Ever since it became clear that about 50% of human cancers contain mutations in p53, this gene has been intensively studied as a cellular defense against transformation. The p53 transcriptional ...
However, it can also be usedto maintain persistence and evade checks for usual persistence mechanisms. An attacker with Administrator's rights can use the setnotifycmdline option to create a persistent job and thenspecify a /Resume optionat a later time to execute the job. This mechanism allows...
The solution must extend the current email mechanisms when adding a trust mechanism. Part of the solution is for the sender to implement a Sender Policy Framework (SPF) text record in the Domain Name System (DNS). The SPF record lists which IP addresses are permitted to email on behalf of...
1. Introduction After the introduction of deep learning [9, 42] and at- tention mechanisms [45, 46] to multi-modal vision and lan- guage research, perhaps one of the most significant develop- ments was the discovery of 'bottom-up' attention [2]. Un- like normal ...
Although there are many individual examples of prophages that express genes that prevent superinfection, it is unclear both how widespread each of these different superinfection resistance mechanisms are and what fitness consequences they have for their hosts. In this study we use P. aeruginosa, an ...
