The lipopeptide iturin from Bacillus subtilis has been found to have a potential inhibitory effect on breast cancer, alveolar adenocarcinoma, renal carcinoma, and colon adenocarcinoma. In this study, the of B. lipopeptides (a mixture homologues, concentration 42.75%) inhibit chronic myelogenous leukemia was evaluated using K562 cells. results showed that could completely growth at 100 μM, with an IC50 value 65.76 μM. inhibited profile via three pathways: (1) induction paraptosis indicated by...
This brief investigates the fixed-time synchronization of complex networks with a simpler nonchattering controller. First, new finite-time stability theorem is proposed. Second, novel sufficient criterion derived for synchronized networks. Compared some existing results, controller without sign function designed to realize synchronization. Moreover, include linear parts, which means than controllers by using finite-/fixed-time methods, and chattering phenomenon can also be avoided. Finally,...
This paper presents a novel gradient-free trust region assisted adaptive response surface method for aircraft optimization problems with expensive functions. A sampling space approach is developed design reduction and sequential sampling, metamodel refitting enables the to possess higher efficiency better global convergence capability. Besides, an election Latin hypercube improve space-filling property feasibility of samples. Moreover, augmented Lagrangian employed handle constraints. The...
This paper studies the problem of exponential outer synchronization between two uncertain nonlinearly coupled complex networks with time delays. In order to synchronize networks, an adaptive control scheme is designed based on Lyapunov stability theorem. Simultaneously, unknown system parameters are identified when occurs. Finally, numerical examples provided demonstrate feasibility and effectiveness theoretical results.
Google services continuously generate vast amounts of application data. This data provides valuable insights to business users. We need store and serve these planet-scale sets under the extremely demanding requirements scalability, sub-second query response times, availability, strong consistency; all this while ingesting a massive stream updates from applications used around globe. have developed deployed in production an analytical management system, Napa, meet requirements. Napa is...
This manuscript investigated the response of a strongly non-linear vibro-impact (VI) system with Coulomb friction. The impact model is used classical impact. excitation modelled by real noise. First, VI converted into simplified without any barrier non-smooth transformation (symmetric transformation). stochastic averaging method adopted to obtain theoretical stationary probability function system. Next, Duffing Van der Pol friction verify validity proposed compared numerical simulations....

Abstract In this article, a novel globally exponentially convergent velocity observer for class of mechanical systems with l nonholonomic constraints is presented. Through using special coordinate transformation, the constrained system converted into integral cascade Euler–Lagrange form, which could avoid solving partial differential equations and eliminate influence constraint force when reconstructing speed information. The proposed has simple structure lower dimensions compared other...
Aimed to the security and privacy issues which restrict construction development of Internet Things, a WSN-oriented key agreement protocol in Things ( IOT) has been proposed . Trust management was introduced mechanism IOT, use bilinear pairing technology, identity-based realized. Using not only can effectively prevent attacks from outside network recognize abnormal nodes were captured or lapsed efficacy. Thus it reduce communication with improve security, extending lifetime network. The...
This paper proposed an observer-based output feedback tracking controller with constraints for the rigid-link flexible-joint space manipulator system considering dynamic damping caused by torque change. By combining Barrier Lyapunov function, backstepping, coordinate transformation, scaling, and globally exponentially convergent velocity observer, scheme maintains simplicity of independent design observer controller, where observation gains control can be designed separately.
P2P storage systems have a lot of attractive advantages, such as self-organizing, scalability, robust and fault-tolerant. Unfortunately, there are some problems in real network conditions, especially, when considering asynchronous wide-area networks, where messages may be delayed indefinitely nodes fail. So, failure detector is one basic components to build reliable systems. Considering the highly dynamic characteristics distributed system, novel detector, which can combine heartbeat...
