In TREC 2012, we participated in the search and filtering tasks of the Microblog Track. The Microblog track is in its second year, and whilst the real-time ad-hoc search task remained very similar to 2011, a new real-time filtering task was introduced. For both tasks, we made use of temporal evidence and a burst detection algorithm to re-rank documents created during bursty periods. We also mad...

The optical response of hierarchical materials is convoluted, which hinders their direct study and property control. Transparent wood (TW) an emerging biocomposite in this category, adds function to the structural properties wood. Nano- microscale inhomogeneities composition, structure at interfaces strongly affect light transmission haze. While interface manipulation can tailor TW properties, ...

Transparent wood (TW), a biocomposite material demonstrating optical transparency in the visible range, has attracted much interest recent years due to great potential for ecofriendly applications, instance, construction industry and functionalized organic materials. Optical properties of TW, including haze, depend on particular structure cellulose‐based backbone compound, (mis‐)matching refrac...

Austenitic stainless steels (AISI316) are used for many commercial and industrial applications for their excellent corrosive resistance. AISI316 is generally difficult to machine material due to their high strength and high work hardening tendency. Tool wear (TW) and surface roughness (SR) are broadly considered the most challenging phases causing poor quality in machining. Optimization of cutt...

Two fractions ET-1 and TW isolated from Terminalia arjuna were evaluated for their antimutagenic potential against 4-nitro-o-phenylenediamine (NPD) in TA98, sodium azide in TA100 and 2-aminofluorene, in both TA98 and TA100 tester strains of Salmonella typhimurium using bacterial reverse mutation assay. Both the fractions inhibited the mutagenicity of 2AF significantly in both the strains. ET-1 ...

Bioremediation is a promising technique for cleaning contaminated soil. We study an idealized bioremediation model involving a substrate (contaminant to be removed), electron acceptor (added nutrient), and microorganisms in a one-dimensional soil column. Using geometric singular perturbation theory, we construct traveling waves (TW) corresponding to motion of a biologically active zone, in whic...

The quantum transport through Tour Wires (TWs) was studied at room temperature and high temperature range using nonequilibrium Green’s function (NEGF) formalism combined with extended Huckel theory (EHT). AuTour Wire-Au junctions were constructed with functional groups NO2 and NH2.The influence of the temperature effect on the transport characteristics have been emphasized, and the result shows...
