Antimicrobially active cycloundecapeptides related to gramicidin S, cyclo(-Val1-Orn2-Leu3-X4-D-Phe5-Pro6-Val7-Orn8- Leu9-D-Phe10-Pro11-) (X= Leu (1), Ala (2), Orn (3), Lys (4) and Arg (5)), were synthesized. From the CD and NMR studies, 1-5 possess antiparallel -sheet conformation linked by a type II -turn around D-Phe10-Pro11 and a novel turn structure around X4-D-Phe5-Pro6 sequence with cis D...
Abstract: Two models of mini-flying robots with four rotors called X4-flyer presented and studied for the stabilization. Both cases with and without motion planning are proposed in this paper. The first is called inertial model with axes orientation and the second is called the inertial model without axes orientation. The control algorithm of the X4-flyer is based on the Lyapunov method and obt...
In this paper we find all primitive solutions of Thue inequality |x4 + 2(1− n)xy + y4| ≤ 2n + 3, where n ≥ 3 is an integer.
This chapter describes kinodynamic motion planning and its application. Kinodynamics is the discipline that tries to solve kinematic constraints and dynamical constraints simultaneously. By using kinodynamic motion planning, control inputs can be generated in a much simpler way, compared to the conventional motion planning that solves kinematics and dynamics separately. After briefly overviewin...
