The present study emphasizes mixed-method analysis, integrating the partial least square structural equation model (PLS-SEM) and customer journey for mobile pocket office improvement in logistic XYZ company. extension of unified theory acceptance use technology (UTAUT 2) by incorporating perceived risk (PR), personal innovativeness (PI), trust (TR) variables are used. sample this consisted 243 ...

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...

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...

BACKGROUND Buruli ulcer is a neglected tropical disease caused by Mycobacterium ulcerans. This skin disease is the third most common mycobacterial disease and its rapid diagnosis and treatment are necessary. Polymerase chain reaction (PCR) is considered to be the most sensitive method for the laboratory confirmation of Buruli ulcer. However, PCR remains expensive and involves reagents unsuitabl...

BACKGROUND There will be increasing pressure to publicly report and rank the performance of healthcare systems on human immunodeficiency virus (HIV) quality measures. To inform discussion of public reporting, we evaluated the influence of case-mix adjustment when ranking individual care systems on the viral control quality measure. METHODS We used data from the Veterans Health Administration ...
