New results on the genetic cryptanalysis of TEA and reduced-round versions of XTEA
No full textCongress on Evolutionary Computation. Portland, USA, 19-23 June 2004Recently, a simple way of creating very efficient distinguishers for cryptographic primitives such as block ciphers or hash functions, was presented by the authors. Here, this cryptanalysis attack is shown to be successful when applied over reduced round versions of the block cipher XTEA. Additionally, a variant of this genetic attack is introduced and its results over TEA shown to be the most powerful published to date

Profiling of Soluble Neutral Oligosaccharides from Treated Biomass using Solid Phase Extraction and Liquid Chromatography-Multiplexed Collision Induced Dissociation-Mass Spectrometry
No full textThermochemical pretreatment of cellulosic biomass improves cell wall enzymatic digestibility, while simultaneously releasing substantial amounts of soluble oligosaccharides. Profiling of oligosaccharides released during pretreatment yield information essential for choosing glycosyl hydrolases necessary for cost-effective conversion of cellulosic biomass to desired biofuel/biochemical end-products. In this report we present a methodology for profiling of soluble neutral oligosaccharides released from ammonia fiber expansion (AFEXTM)-pretreated corn stover. Our methodology employs solid phase extraction (SPE) enrichment of oligosaccharides based on porous graphitized carbon (PGC), followed by high performance liquid chromatography (HPLC) separation using a polymeric amine based column (Prevail Carbohydrate ES) and electrospray ionization time-of-flight mass spectrometry (ESI-TOF-MS) in both positive and negative modes. For structural elucidation on the chromatographic time scale, nonselective multiplexed collision-induced dissociation was performed for quasi-simultaneous acquisition of accurate molecular and fragment masses of neutral oligosaccharids in a single analysis. These analyses directly revealed presence of glucans up to degree of polymerization (DP) 22 without side-chain modifications. Additionally, arabinoxylans with DP up to 6 were detected in the pretreated biomass samples (post-enzymatic digestion). All linkages between sugar units in glucans and arabinoxylans were identified to be p-1-4 linkages based on cross-ring fragment masses. Comprehensive profiling of soluble oligosaccharides also demonstrated that arabinoxylan acetylation was reduced by greater than 85% post-AFEXTM treatment.Published version: Vismeh, Ramin, Humpula, James F., Chundawat, Shishir P.

Triple decomposition of a fluctuating velocity field in a multiscale flow
No full textA method for the triple decomposition of fluctuating velocity in a multiscale flow, suitable for a spatiotemporal data set, is presented. It is applied to experimental data gathered by means of particle image velocimetry (PIV). The basic properties of the decomposed parts are shown. The presented method is then used to perform a conditional study on the residual transverse velocity fluctuations. It was found that phase locking occurs between the stochastic fluctuations embedded in the wakes of different bars, appearing after the wakes have merged
Consumer Demand and Welfare under Increasing Block Pricing
No full textThis paper argues that an increasing block pricing structure needs to be supplemented by allowances for household size and composition to be equitable. Household behaviour is modelled as the outcome of a two-stage budgeting resulting in an integrable water demand model. The welfare effects of block pricing are studied using the concept of relative equivalence scale, modified to allow for the dependence of price on household size and composition. We use individual household data to estimate residential demand for water, provide empirical illustration of the welfare effects of increasing block pricing on demographically different households and show how these effects can be compensated.relative equivalence scales, price endogeneity, demand for water
Probing the nature of AFEX-pretreated corn stover derived decomposition products that inhibit cellulase activity
No full textSequential fractionation of AFEX-pretreated corn stover extracts was carried out using ultra-centrifugation, ultra-filtration, and solid phase extraction to isolate various classes of pretreatment products to evaluate their inhibitory effect on cellulases. Ultra-centrifugation removed dark brown precipitates that caused no appreciable enzyme inhibition. Ultra-filtration of ultra-centrifuged AFEX-pretreated corn stover extractives using a 10 kDa molecular weight cutoff (MWCO) membrane removed additional high molecular weight components that accounted for 24–28% of the total observed enzyme inhibition while a 3 kDa MWCO membrane removed 60–65%, suggesting significant inhibition is caused by oligomeric materials. Solid phase extraction (SPE) of AFEX-pretreated corn stover extractives after ultra-centrifugation removed 34–43% of the inhibition; ultra-filtration with a 5 kDa membrane removed 44–56% of the inhibition and when this ultra-filtrate was subjected to SPE a total of 69–70% of the inhibition were removed. Mass spectrometry found several phenolic compounds among the hydrophobic inhibition removed by SPE adsorption.Published version: Humpula, James F., Uppugundla, Nirmal, Vismeh, Ramin, Sousa, Leonardo, Chundawat, Shishir P.

Fransen).</p> <p> <b>Remarks.</b> The species, first reported in association with antipatharians from Madagascar, was originally described and illustrated by Bruce (1978). The specific granulation of the major chelipeds is discussed for other <i>Periclimenes</i> -like pontoniine shrimps in the remarks to the original description and, later, by the same author (Bruce 1990) in his comments for <i>Periclimenes tonga</i>. In the latter report, the author pointed out (p. 31) the fact that in <i>P. granulimanus</i>, “the distal propod and dactyl of the ambulatory [leg] appear to form a prehensile mechanism”. The prehensile structures are almost identical to those of <i>P. laevimanus</i> sp. nov., and are more thoroughly discussed in <b>Remarks</b> for <i>P. laevimanus</i> and <i>P. brucei</i> (above), and in the <b>Discussion</b> (below).</p> <p> <i>P. granulimanus</i> is closely similar to <i>P. laevimanus</i> sp. nov. Together with the major cheliped granulation noted above, this species also differs by stouter proportions of the cheliped: the palm is 5 times longer than deep and 3.5 times longer than the fingers, while the porportions are 6.6–8.0 times and 4.0–4.5 times, respectively, in adults of the new species, but in juveniles these relations may be approx. 3.5 and 1.8 times, respectively. The major second pereiopod carpus is subequal to the fingers in the female holotype of <i>P. granulimanus</i>, but approximately 2 times longer in adults of <i>P. laevimanus</i> sp. nov. (subequal in juveniles). The minor chela has 1 and 2 shallow teeth on the cutting edges of the fixed finger and the dactylus, respectively; these are lacking in the new species. No noticeable thoracic sternal structures were encountered in <i>P. laevimanus</i> sp. nov., while a small median tubercle was reported on the fourth and eighth sternites, and a shallow median notch on the fifth to seventh sternites in <i>P. granulimanus</i> (Bruce 1978). The accessory pigment spot and the arthrobranch on the third maxilliped were reported as lacking in the holotype of <i>P. granulimanus,</i> with the latter being possibly lost during dissecting of the holotype (Bruce 1978). Both these structures are present in other species of the <i>P. granulimanus</i> species group discussed in this work. The examination of the RMNH specimens of <i>P. granulimanus</i>, by C.H.J.M. Fransen (pers. comm.), prove that the accessory pigment spot was present as a very small dot, dorsally in the posterior margin of the cornea, but almost indistinguishable from the rest of the cornea. A small 2-lamellate arthrobranch is also present on the third maxilliped.</p> <p> <b>Color.</b> Not reported.</p> <p> <b>Host.</b> Unidentified antipatharian (Bruce 1978); a bushy hydroid, <i>Lytocarpus philippinus</i> (Kirchenpauer), 24 m (Bruce 1981); <i>Virgularia</i> sp.
