Prêt à Voter is a supervised, end-to-end verifiable voting scheme. Informal analyses indicate that, subject to certain assumptions, Prêt à Voter is receipt free, i.e. a voter has no way to construct a proof to a coercer of how she voted. In this paper we propose a variant of Prêt à Voter and prove receipt freeness of this scheme using computational methods. Our proof shows that if there exists ...

Consider the provable security of RSA-OAEP when not instantiated with random oracles. Suppose a security reduction exists to show that finding a plaintext from a RSA-OAEP ciphertext (breaking the basic OW-CPA security) is as hard as the RSA problem. • The reduction can be used in an adaptive chosen ciphertext text (IND-CCA2) attack against RSA-OAEP. • The reduction cannot succeed in the random ...

In the first part of this study, agar dilution MICs were used to test the activities of trovafloxacin, ciprofloxacin, ofloxacin, levofloxacin, sparfloxacin, clinafloxacin, ceftazidime, and imipenem against 458 gram-negative nonfermenters. The overall respective MICs at which 50% of isolates are inhibited (MIC50s) and MIC90s were as follows: trovafloxacin, 1.0 and 16.0 microg/ml; ciprofloxacin, ...

Oil palm (Elaeis guineensis) is a species of tree cultivated mainly for its oil. Malaysia the second largest producer oil behind Indonesia. During harvesting fruit bunch, some over ripped fruits will get detached from bunch and these loose be contaminated with bacteria soil. Collecting ground normally done manually by hand this may allow transmission soil to workers.

Plant-associated microbes are important for the growth and health of their hosts. As a result of numerous prior studies, we know that host genotypes and abiotic factors influence the composition of plant microbiomes. However, the high complexity of these communities challenges detailed studies to define experimentally the mechanisms underlying the dynamics of community assembly and the benefici...

Pantoea ananatis is ubiquitously found in the environment and causes disease on a wide range of plant hosts. By contrast, its sister species, Pantoea stewartii subsp. stewartii is the host-specific causative agent of the devastating maize disease Stewart's wilt. This pathogen has a restricted lifecycle, overwintering in an insect vector before being introduced into susceptible maize cultivars, ...

Bloodstream infection (BSI) is an important cause of morbidity and mortality in patients undergoing hematopoietic stem cell transplantation (HSCT). To evaluate the causative bacteria and identify risk factors for BSI associated mortality in febrile neutropenia patients undergoing HSCT, we collected the clinical and microbiological data from patients underwent HSCT between 2008 and 2014 and perf...
