U-turns on ant pheromone trails

Many ant species use branching networks of pheromone trails for orientation between nest and resources [1–3]. Ants on trails make adaptive U-turns for correcting their course using visual cues [4,5] or trail geometry information [2]. However, the role of seemingly non-corrective U-turns on trails is poorly understood. We found that a minority of ants consistently make frequent and seemingly ina...

Ranking Efficient Units in DEA by Using TOPSIS Method

There exist many different ranking methods for ranking efficient Decision Making Units (DMUs) in Data Envelopment Analysis (DEA). However, since each of these methods considers a certain theory for ranking, they may give different ranks. In practice, choosing a ranking method, the results of which the Decision Maker (DM) would be able to trust is an important issue. In this paper, we consider s...

Development of a New Jughandle Design for Facilitating High- Volume Left Turns and U-turns

Revisiting GNRA and UNCG folds: U-turns versus Z-turns in RNA hairpin loops.

When thinking about RNA three-dimensional structures, coming across GNRA and UNCG tetraloops is perceived as a boon since their folds have been extensively described. Nevertheless, analyzing loop conformations within RNA and RNP structures led us to uncover several instances of GNRA and UNCG loops that do not fold as expected. We noticed that when a GNRA does not assume its "natural" fold, it a...
