The ejection of internal organs, i.e., evisceration, is a well-known phenomenon in sea-cucumbers. We report the ability of a member of the Chordate phyla, the tropical ascidian Polycarpa mytiligera, to eviscerate and regenerate its gut within 12 days, and to rebuild its branchial sac within 19 days. Evisceration occurred within 4-43 seconds of gentle mechanical pressure exerted on the tunic in ...

In this paper, we did a comprehensive survey on the evolution of defense in Linux softwares. Our survey mainly focused on Stack Canary, CFI and ASLR. In order to measure the coverage of Stack Canary, we collected more than 1 million package data. Besides, we also found that ASLR is an operating system behavior, and CFI was still not widely implemented in production compilers. Beyond the survey,...

Abstract It is well known that weak hydraulic jumps and bores develop a growing number of surface oscillations behind the bore front. Defining strength as ratio head undular to undisturbed depth, it was found in classic work Favre (Ondes de Translation. Dunod, Paris, 1935) regime laminar flow demarcated from partially turbulent flows by sharply defined value 0.281. This critical characterized e...

Surfaces equiptment may facilitate contamination carcasses due bacterial adherence and transfer. In this study, attachment, proliferation, detachment Salmonella Enteritidis Escherichia coli were comparatively investigated on uncoated silica-coated stainless-steel surfaces....

One giant manufacturer (M1) upgrades a common supplier’s production technology through investments, while the supplier (it), holding spillover information privately, may spill upgraded over to rival (M2). This study examines whether should share of with M1. We first find hurts not only M1 but also and M2, when cost is high investment low at level real degree, no matter shares or not. As such, i...

with Hypaque was performed before the expected date of ovulation, and laparoscopy before menstruation.' All but one of the laparoscopies were performed under local anaesthesia2 with about 30 ml aqueous methylene blue injected under low pressure into the uterine cavity. On laparoscopy the dye could be seen traversing patent tubes and spilling into the pouch of Douglas. Bilateral tubal patency wa...

BACKGROUND: Coronary artery fistula is an abnormal communication between a coronary artery and a cardiac chamber or major cardiac vessels, mostly congenital but some of them are acquired as a consequence of coronary artery perforation. CASE PRESENTATION: We report a case of cavity spilling coronary artery perforation during percutaneous coronary intervention 7 years ago. Because of continuing s...
