Musa beccarii *** var. beccarii and Musa beccarii *** var. hottana H?kkinen were described earlier in Acta Phytotaxonomica et Geobotanica based on their morphological characteristics. In order to distinguish the genomes between the two M. beccarii varieties and M. coccinea Andrews, we have now studied them with the Inter- Retrotransposon Amplified Polymorphism (IRAP) marker analyses. The high levels of IRAP polymorphism detected in this study showed that M. beccarii var. beccarii and M. beccarii var. hottana are two distinct varieties. Additional IRAP bands found in M. beccarii var. beccarii indicated that M. beccarii var. hottana might be evolutionarily more ancient than M. beccarii var. beccarii because LTR retrotransposons are not transpositionally removed.

A single-channel electroencephalography(eeG)device,despite being widely accepted due to convenience,ease of deployment and suitability for use in complex environments,typically poses a great challenge for reactive brain-computer interface(BCI)applications particularly when a continuous command from users is desired to run a motorized actuator with different speed *** this study,a combination of an inconspicuous visual stimulus and voluntary eyeblinks along with a machine learning-based decoder is considered as a new reactive BCI paradigm to increase the degree of freedom and minimize mismatches between the intended dynamic command and transmitted control *** proposed decoder is constructed based on Gaussian Process model(GPM)which is a nonparametric Bayesian approach that has the advantages of being able to operate on small datasets and providing measurements of uncertainty on *** evaluate the effectiveness of the proposed method,the GPM is compared against other competitive techniques which include k-Nearest Neighbors,linear discriminant analysis,support vector machine,ensemble learning and neural *** demonstrate that a significant improvement can be achieved via the GPM approach with average accuracy reaching over 96%and mean absolute error of no greater than 0.8 cm/*** addition,the analysis reveals that while the performances of other existing methods deteriorate with a certain type of stimulus due to signal drifts resulting from the voluntary eyeblinks,the proposed GPM exhibits consistent performance across all stimuli considered,thereby manifesting its generalization capability and making it a more suitable option for dynamic commands with a single-channel eeG-controlled actuator.

It has been witnessed that swarm systems are superior to individual agents in performing complicated tasks. In recent years, new results in some branches of control for swarm systems have developed and investigated with respect to various objectives and scenarios. This survey is to take a glimpse into some newly developed control techniques for swarm systems, especially those presented after 2013. The covered topics include some up-to-date progress in the areas of consensus, formation, flocking, containment, optimal coverage/mission planning, and sensor networks. Contributions and connections of the mentioned references are discussed *** on the new results in control of swarm systems, some possible new future research topics are suggested.

The World Health Organisation （WHO） launched a global action plan on physical activity to provide a frame- work of policy actions to increase physical activity in June 2018. Physical activity is an effective intervention for pre- vention and management of non-communicable diseases including cardiac disease, regardless of age. We hoped this letter would remind readers of the importance of physical activity in older people, particularly those with cardiac co-morbidities.

A switched system is a dynamic system that operates by switching between different subsystems or *** systems exhibit both continuous and discrete characteristics—a dual nature that makes designing effective control policies a challenging *** purpose of this paper is to review some of the latest computational techniques for generating optimal control laws for switched systems with nonlinear dynamics and continuous inequality *** discuss computational strategies for optimizing both the times at which a switched system switches from one mode to another(the so-called switching times)and the sequence in which a switched system operates its various possible modes(the so-called switching sequence).These strategies involve novel combinations of the control parameterization method,the timescaling transformation,and bilevel programming and binary relaxation *** conclude the paper by discussing a number of switched system optimal control models arising in practical applications.
