Recently, an increase in incidences of urinary tract infections in uncircumcised male infants has been reported. However, determining what is the best management for the prepuce of newborns and infants is still to be solved. I investigated prospectively how much foreskins are retracted with age and what correlations it has with urinary tract infection in 122 males children below 15 years of age...

According to the problem in communication protocol security assessments, a new protocol security comprehensive evaluation method based on the threedimensional sphere model is presented. In this method, a three-dimensional security evaluation index system was built through positions of index on the external of spherical shell. Evaluation index weights of the top two levels were obtained through ...

Recently a number of requirements engineer­ ing languages and methods have flourished that do not only address what questions but also why, who and when questions. The objective of this paper is twofold: (i) to assess the strengths and weaknesses of one of these meth­ odologies on a non-trivial benchmark, and (ii) to illustrate and discuss a number of challenging issues that need to be addresse...

Aspects of feeding, such as food capture and ingestion, as well as mobility of the polychaetes Eurythoe complanata, Marphysa formosa and Diopatra aciculata, from São Sebastião Channel (São Sebastião, state of São Paulo) were observed in laboratory conditions. Eurythoe complanata, a carnivorous species, fed exclusively on pieces of fish with the aid of strong muscular retractable lips, and detec...

The Lophotrochozoa includes disparate tentacle-bearing sessile protostome animals, which apparently appeared in the Cambrian explosion, but lack an uncontested fossil record. Here we describe abundant well preserved material of Cotyledion tylodes Luo et Hu, 1999, from the Cambrian (Series 2) Chengjiang deposits, reinterpreted here as a stem-group entoproct. The entoproct affinity is supported b...

Endoscopic third ventriculostomy is a procedure used to treat hydrocephalus by making a perforation in the floor of the third ventricle of the brain under endoscopic guidance. We report on our initial experience in developing an endoscopic third ventriculostomy simulator for neurosurgery residents, including the definition of the simulation content and integration on NeuroTouch, a simulator for...

BACKGROUND Peripheral intravenous catheters are among the most widely used medical devices in the world. European patients are increasingly aware of the risk of health care associated infections and the role catheters play in their facilitation. AIMS We intend to show that European health care providers are increasingly aware of the occupational risks of bloodborne infections such as HIV and ...

Cats have retractable claws which are versatile tools used for climbing, defence, balance, scratching and catching prey. They are also a formidable weapon which can inflict nasty scratches to animals perceived by the cat to be a threat (or a nuisance!). The most frequent victim is a younger dog, which is typically curious and has not yet learned to read hostile signals. They also do not develop...

We present Strain, a new auction protocol running on top of blockchains and guaranteeing bid confidentiality against fully-malicious parties. As our goal is efficiency and low blockchain latency, we abstain from using traditional, highly interactive MPC primitives such as secret shares. Instead for Strain, we design a new maliciouslysecure two-party comparison mechanism executed between any pai...
