TL;DR: A multi-robotic exploration with the requirement of communication link to a fixed base station is presented and comparisons portray performance gain in terms of exploration time and absence of deadlocks vis-a-vis the few methods previously reported in the literature.
Abstract: A multi-robotic exploration with the requirement of communication link to a fixed base station is presented in this paper. The robots organize themselves into roles of maintainers of communication (hinged robots or robot nodes) or explorers of the environment ensuring that every robot is in contact with the base station directly or through the hinged robots. A two phased strategy for the same is presented. The first phase is characterized by a recursive growth of trees that starts from the root node or the base station and then repeated from other nodes of the hitherto grown tree in a depth first fashion. The second phase constitutes the recursive tree growth invoked repeatedly from the frontier nodes. While the first phase rapidly explores areas around the base station in a concentric fashion, the second phase extends the depth of the explored area to increase the limits of coverage. The strategy is consistent in that none of the robots loose contact with the base station. Extensive simulations confirm the efficacy of the method and comparisons portray performance gain in terms of exploration time and absence of deadlocks vis-a-vis the few methods previously reported in the literature.

TL;DR: The reversible logic implementation of the modified conventional, as well as the proposed, carry look-ahead and carry skip BCD subtractors efficient in terms of the number of reversible gates used and garbage output produced are introduced.
Abstract: Reversible logic is emerging as a promising computing paradigm, having its applications in low-power CMOS, quantum computing, nanotech-nology and optical computing. Firstly, we showed a modified design of conventional BCD subtractors and also proposed designs of carry look-ahead and carry skip BCD subtractors. The proposed designs of carry look-ahead and carry skip BCD subtractors are based on the novel designs of carry look-ahead and carry skip BCD adders, respectively. Then, we introduced the reversible logic implementation of the modified conventional, as well as the proposed, carry look-ahead and carry skip BCD subtractors efficient in terms of the number of reversible gates used and garbage output produced. To the best of our knowledge, the carry look-ahead and carry skip BCD subtractors and their reversible logic design are explored for the first time ever in literature.

TL;DR: PETIM dendrimers have relatively greater hydrophobicity and flexibility when compared with their extensively investigated PAMAM counterparts, which is expected to have stronger interactions with lipid membranes as well as improved drug encapsulation and retention properties when compared.
Abstract: A new class of dendrimers, the poly(propyl ether imine) (PETIM) dendrimer, has been shown to be a novel hyperbranched polymer having potential applications as a drug delivery vehicle. Structure and dynamics of the amine terminated PETIM dendrimer and their changes with respect to the dendrimer generation are poorly understood. Since most drugs are hydrophobic in nature, the extent of hydrophobicity of the dendrimer core is related to its drug encapsulation and retention efficacy. In this study, we carry out fully atomistic molecular dynamics (MD) simulations to characterize the structure of PETIM (G2-G6) dendrimers in salt solution as a function of dendrimer generation at different protonation levels. Structural properties such as radius of gyration (Rg), radial density distribution, aspect ratio, and asphericity are calculated. In order to assess the hydrophilicity of the dendrimer, we compute the number of bound water molecules in the interior of dendrimer as well as the number of dendrimer-water hydrogen bonds. We conclude that PETIM dendrimers have relatively greater hydrophobicity and flexibility when compared with their extensively investigated PAMAM counterparts. Hence PETIM dendrimers are expected to have stronger interactions with lipid membranes as well as improved drug encapsulation and retention properties when compared with PAMAM dendrimers. We compute the root-mean-square fluctuation of dendrimers as well as their entropy to quantify the flexibility of the dendrimer. Finally we note that structural and solvation properties computed using force field parameters derived based on the CHARMM general purpose force field were in good quantitative agreement with those obtained using the generalized Amber force field (GAFF).

TL;DR: The experiments of Language Technologies Research Centre (LTRC) 1 are presented as part of their participation in CLEF 2 2006 ad-hoc document retrieval task and Hindi and Telugu to English CLIR system is discussed.
Abstract: This paper presents the experiments of Language Technologies Research Centre (LTRC) 1 as part of their participation in CLEF 2 2006 ad-hoc document retrieval task. This is our first participation in the CLEF evaluation tasks and we focused on Afaan Oromo, Hindi and Telugu as query languages for retrieval from English document collection. In this paper we discuss our Hindi and Telugu to English CLIR system and the experiments at CLEF.
