The risk of blood-borne transmission of infectious diseases has led to an increasing awareness of the need for a safe and effective pathogen reduction technology. This study evaluated the efficacy of 2 pathogen reduction systems to inactivate dengue virus (DENV-2) and chikungunya virus (CHIKV) spiked into apheresis platelets (APLT) concentrates. Double-dose APLT collections (n = 3) were split e...

In this paper we systematically study the differential properties of addition modulo 2n. We derive (log n)-time algorithms for most of the properties, including differential probability of addition. We also present log-time algorithms for finding good differentials. Despite the apparent simplicity of modular addition, the best known algorithms require naive exhaustive computation. Our results r...

We continue the analysis of higher and multiple Mahler measures using log-sine integrals as started in “Log-sine evaluations of Mahler measures” and “Special values of generalized log-sine integrals” by two of the authors. This motivates a detailed study of various multiple polylogarithms and worked examples are given. Our techniques enable the reduction of several multiple Mahler measures, and...

Abstract Communities are now turning to potable reuse augment their water supply portfolios in response increasing demand and climate uncertainty. One barrier broader implementation is a lack of regulations for direct (DPR) some locations. An incomplete understanding the foundation existing DPR frameworks may be contributing this barrier. The objective study was use publicly available quantitat...

Abstract Plasticised cassava starch films with 1–2% ferulic or cinnamic acid were obtained by melt blending and compression moulding. Partial losses (about 40%) of the more thermo-sensitive occurred during processing. Incorporation phenolic acids did not provoke remarkable changes in oxygen water vapour permeability films, but these became less soluble (13–25% reduction), extensible resistant t...

Seven species of bacterial biothreat agents were tested for susceptibility to UV light (254 nm). All gram-negative organisms tested required <12 mJ/cm(2) for a 4-log(10) reduction in viability (inactivation). Tailing off of the B. anthracis spore inactivation curves began close to the 2-log(10) inactivation point, with a fluence of approximately 40 mJ/cm(2), and 3-log(10) inactivation still was...

In this paper we first define a reduction Æ that transforms an instance of Regular-SAT into a satisfiability equivalent instance Æ of SAT. The reduction Æ has interesting properties: (i) the size of Æ is linear in the size of , (ii) Æ transforms regular Horn formulas into Horn formulas, and (iii) Æ transforms regular 2-CNF formulas into 2-CNF formulas. Second, we describe a new satisfiability t...
