Class Responsibility Collaborator (CRC) Cards can be used in developing Object-Oriented models. They provide a simple and an easy to use way to explore objects in the development of a system. However, different problems might arise while adopting current CRC-Cards in identifying the system objects. In this paper, we discuss the main problems with current CRC-Cards. As a solution, we propose a n...

UNLABELLED Mycoplasma pneumoniae synthesizes a novel human surfactant protein A (SP-A)-binding cytotoxin, designated community-acquired respiratory distress syndrome (CARDS) toxin, that exhibits ADP-ribosylating and vacuolating activities in mammalian cells and is directly linked to a range of acute and chronic airway diseases, including asthma. In our attempt to detect additional CARDS toxin-b...

The “five-card trick” invented by Boer allows Alice and Bob to securely compute the AND function of their secret inputs using five cards—three black cards and two red cards—with identical backs. This paper shows that such a secure computation can be done with only four cards. Specifically, we give a protocol to achieve a secure computation of AND using only four cards—two black and two red. Our...
