Marcus et al. (2011) describe using Amazon’s Mechanical Turk (MTurk) systems utilizing crowds for database sorts and joins. Crowdsourcing activities for these types of queries are typical costly in order to ensure accuracy and reliability. The authors present an interface for optimizing these functions in order to determine cost-effectiveness of various methods (simple join, naïve batching, and...

T cells from nonimmune responder strain 2 guinea pigs were primed in vitro to the copolymer GL in association with allogeneic, nonresponder strain 13 PEC. T cells that recognized GL in association with strain 13 Ia were separated from alloreactive T cells by cloning the population in soft agar following the priming in liquid culture. The existence of T cells of responder origin that recognize a...

The ability of spleen cells from (responder X nonresponder)F(1) mice immunized with various GAT-Mphi, GAT-MBSA, and soluble GAT to develop IgG GAT-specific PFC responses in vitro after stimulation with responder and nonresponder parental and F(1) GAT-Mphi, was investigated. F(1) spleen cells from mice immunized with F(1) GAT-Mphi or GAT-MBSA developed secondary responses to responder and nonres...

Denial of Service (DoS) attacks are an increasing problem for network connected systems. Key establishment protocols are applications that are particularly vulnerable to DoS attack as they are typically required to perform computationally expensive cryptographic operations in order to authenticate the protocol initiator and to generate the cryptographic keying material that will subsequently be...

The cellular basis of the genetic control of the immune response to poly(LTyr, LGlu)-polyDLAla--polyLLys [(T,G)-A--L] in SJL (H-2s, low responder) mice has been investigated using T-cell factors. Thymocytes of SJL origin were educated to (T,G)-A--L and tested for their ability to produce an antigen-specific factor capable of cooperating in vivo with bone marrow cells of either SJL or C3H.SW (hi...
