Protein secretion systems that mediate interbacterial competition secret a wide repertoire of antibacterial toxins. A major player in these competitions is the newly discovered bacterial type VI secretion system (T6SS). We recently found that a subset of polymorphic MIX-effectors, which are a widespread class of effectors secreted by T6SSs, are horizontally shared between marine bacteria and ar...

The theory of constraints is an approach to production planning and control that emphasizes on the constraints to increase throughput by effectively managing constraint resources. One application in theory of constraints is product mix decision. Product mix influences the performance measures in multi-product manufacturing system. This paper presents an alternative approach by using of goal pro...

This paper introduces the concept of “revocable unlinkability” for unlinkable anonymous signatures and proposes a generalized scheme that modifies the signatures to include revocable unlinkability. Revocable unlinkability provides a condition in which multiple messages signed using an unlinkable anonymous signature are unlinkable for anyone except the unlinkability revocation manager. Noteworth...

A MIX net takes a list of ciphertexts (c1, · · · , cN ) and outputs a permuted list of the plaintexts (m1, · · · ,mN ) without revealing the relationship between (c1, · · · , cN ) and (m1, · · · ,mN ). This paper first shows that the Jakobsson’s MIX net of Eurocrypt’98, which was believed to be resilient and very efficient, is broken. We next propose an efficient t-resilient MIX net with O(t) s...

“MIX-net” systems protect the privacy of participants by clouding together their transactions through cascades of third parties. Reliability and trust are therefore open issues in this literature and limit the applicability of these systems. This paper discusses how the MIX approach can be adapted to put the user at the center of the protocol and in control of it, so that each participant can t...

Abstract This report examines the behavior of a reinforced concrete slab, part an experimental structure, under loads derived from casting formwork system subsequent plate and laid mix in slab above it. The deflections individual stages were measured with help dial gauges. full strength deformation characteristics concretes used construction researched. at all loading was studied, including eac...

This paper presents an analysis of mixes and dummy traffic policies, which are building blocks of anonymous services. The goal of the paper is to bring together all the issues related to the analysis and design of mix networks. We discuss continuous and pool mixes, topologies for mix networks and dummy traffic policies. We point out the advantages and disadvantages of design decisions for mixes...
