BACKGROUND Fungal swollenins (SWOs) constitute a class of accessory proteins that are homologous to canonical plant expansins. Expansins and expansin-related proteins are well known for acting in the deagglomeration of cellulose structure by loosening macrofibrils. Consequently, SWOs can increase the accessibility and efficiency of the other enzymes involved in the saccharification of cellulosi...

Post-optimization through local search is known to be a powerful approach for complex optimization problems. In this paper we tackle the problem of optimizing individual activity plans, i.e., plans that concern activities that one person has to accomplish independently of others, taking into account complex constraints and preferences. Recently, this problem has been addressed adequately using ...

Surface wave oscillator (SWO) is an intense subterahertz source based on the interaction of electron beam with a surface in cylindrical corrugated waveguide (CCW). The oversized factor key parameter SWO and ratio CCW diameter to wavelength generated wave. In this study, we experimentally examine 0.1 THz different factors 10 7. For 7, kilowatt class radiation maximum efficiency 8% observed. oper...

This paper treats the problem of managing personal tasks, through an adaptation of the Squeaky Wheel Optimization (SWO) framework, enhanced with powerful heuristics and full constraint propagation. The problem involves preemptive and non-preemptive tasks, with extra constraints imposed on the sizes of and the distances between the parts of each preemptive task. Travelling times are imposed by t...

We study the nature (constructive versus non-constructive) and issue of real-valued representability social welfare orders, on set infinite utility streams, satisfying anonymity asymptotic density-one Pareto axioms. characterize existence representable constructive orders (fulfilling aforementioned axioms) in terms easily verifiable conditions feasible one-period utilities, denoted by Y ⊂ R : a...

Oversubscribed scheduling problems have been approached using both direct representations of the solution space and indirect, permutation-based representations (coupled with a schedule builder to produce the corresponding schedule). In some problem contexts, permutation-based search methods have been shown to outperform schedule-space search methods, while in others the opposite has been shown ...

The evolution of the Semantic Web (SW) depends on novel methodologies to represent the meanings of the huge amount of information available nowadays. Recent proposals in literature have explored new approaches based on Semiotics. The ‘Semiotic Web Ontology’ (SWO) is an attempt to model the information in a more precise way, and, at the same time to be compatible with the SW standards. This pape...

When the spores of filamentous fungi break dormancy, they grow isotropically, adding cell wall material uniformly in every direction. Later they switch to polarized growth, with new material added to the tip of an emerging germ tube. To identify genes involved in the synthesis and localization of cell wall material in filamentous fungi, we screened a collection of temperature-sensitive Aspergil...

The sleeping brain exhibits characteristic slow-wave activity which decays over the course of the night. This decay is thought to result from homeostatic synaptic downscaling. Transcranial electrical stimulation can entrain slow-wave oscillations (SWO) in the human electro-encephalogram (EEG). A computational model of the underlying mechanism predicts that firing rates are predominantly increas...
