A search and rescue robot search method based on flower pollination algorithm and Q-learning fusion algorithm

Plos.org 

by Bing Hao, Jianshuo Zhao, He Du, Qi Wang, Qi Yuan, Shuo Zhao

Search algorithm plays an important role in the motion planning of the robot, it determines whether the mobile robot complete the task. To solve the search task in complex environments, a fusion algorithm based on the Flower Pollination algorithm and Q-learning is proposed. To improve the accuracy, an improved grid map is used in the section of environment modeling to change the original static grid to a combination of static and dynamic grids. Читать дальше...



Structural characteristics in network control of molecular multiplex networks

Plos.org 

by Cheng Yuan, Zu-Yu Qian, Jie Zhou, Shi-Ming Chen, Sen Nie

Numerous real-world systems can be naturally modeled as multilayer networks, providing an efficient tool to characterize these complex systems. Although recent progress in understanding the controlling of synthetic multiplex networks, how to control real multilayer systems remains poorly understood. Here, we explore the controllability and energy requirement of molecular multiplex networks coupled by transcriptional regulatory network... Читать дальше...

Estimation of bargaining effect in the decision of monetary compensation of executive in investment bank: Evidence from China

Plos.org 

by Lina Yu, Hua Zhao

Though numerous empirical and theoretical studies have been conducted on the determinants and effects of executive compensation, empirical evidence regarding the bargaining effect on the monetary compensation decisions of executives, especially in a large emerging economy such as China, remains scarce. In this study, a two-tier stochastic frontier and endogenous correction model was developed to quantitatively estimate the bargaining effect on the monetary compensation decisions of investment bank executives.

Objectives

The aim of this cross-sectional study was to determine the life satisfaction of older people living in a home environment and to find out what predictors influence it.

Methods

The research involved 1,121 older people 60 years and above from the Moravian-Silesian region who live in a home environment. The short form of the Life Satisfaction Index for the Thirds Age (LSITA-SF12) was used to assess life satisfaction. Читать дальше...

Micro-foundations of dynamic capabilities to facilitate university technology transfer

Plos.org 

by Zhongxuan Ma, K. D. Augustijn, I. J. P. De Esch, B. A. G. Bossink

Within the university-industry ecosystem, improvement and innovation of technology transfer involve implementing appropriate dynamic capabilities. To answer the question—What are the micro-foundations of dynamic capabilities in university technology transfer?—this study investigates in-depth organizational-level dynamic capabilities in transferring university-based knowledge to business and society. Two qualitative case... Читать дальше...

Sex specific serum uric acid levels are associated with ischemic changes on ECG and with 20-year all-cause mortality among older adults

Plos.org 

by Yonatan Moshkovits, Adam Goldman, Angela Chetrit, Rachel Dankner

Background

Uric acid is an emerging biomarker for cardiovascular morbidity and mortality, but its association with all-cause mortality and ECG findings remains unestablished, specifically among older adults. We aimed to evaluate the association between serum uric acid (SUA) with incidental findings of ECG abnormalities and with long-term all-cause mortality.

Methods

We conducted a prospective cohort study of 851 community dwelling men and women... Читать дальше...
