Importance-Based Key Basic Event Identification and Evolution Mechanism Investigation of Hydraulic Support Failure to Protect Employee Health

Background: Although hydraulic support can help enterprises in their production activities, it can also cause fatal accidents. Methods: This study established a composite risk-assessment method for hydraulic support failure in the mining industry. The key basic event of hydraulic support failure was identified based on fault tree analysis and gray relational analysis, and the evolution mechanism of hydraulic support failure was investigated based on chaos theory, a synthetic theory model, and cause-and-effect-layer-of-protection analysis (LOPA). Results: After the basic events of hydraulic support failure are identified based on fault tree analysis, structure importance (SI), probability importance (PI), critical importance (CI), and Fussell–Vesely importance (FVI) can be calculated. In this study, we proposed the Fussell–Vesely–Xu importance (FVXI) to reflect the comprehensive impact of basic event occurrence and nonoccurrence on the occurrence probability of the top event. Gray relational analysis was introduced to determine the integrated importance (II) of basic events and identify the key basic events. According to chaos theory, hydraulic support failure is the result of cross-coupling and infinite amplification of faults in the employee, object, environment, and management subsystems, and the evolutionary process has an obvious butterfly effect and inherent randomness. With the help of the synthetic theory model, we investigated the social and organizational factors that may lead to hydraulic support failure. The key basic event, jack leakage, was analyzed in depth based on cause-and-effect-LOPA, and corresponding independent protection layers (IPLs) were identified to prevent jack leakage. Implications: The implications of these findings with respect to hydraulic support failure can be regarded as the foundation for accident prevention in practice.

World Modeling, Integrated Information, and the Physical Substrates of Consciousness; Hidden Sources of the Stream of Experience?

In this brief commentary on The Hidden Spring: A Journey to the Source of Consciousness, I describe ways in which Mark Solms’ account of the origins of subjective experience relates to Integrated World Modeling Theory (IWMT). IWMT is a synthetic theory that brings together different perspectives, with the ultimate goal of solving the enduring problems of consciousness, including the Hard problem. I describe points of compatibility and incompatibility between Solms’ proposal and IWMT, with particular emphasis on how a Bayesian interpretation of Integrated Information Theory and Global (Neuronal) Workspace Theory may help identify the physical and computational substrates of consciousness.

An analytic description of the creep deformation of metals in the ultrasonic field

The effect of superimposed ultrasonic vibration on the primary creep of metals is modeled in terms of the synthetic theory of irrecoverable deformation. We consider two sonication modes: (i) the ultrasound acts continuously during the deformation, and (ii) the ultrasound is periodically on and off. Whereas both cases show a significant increase in primary creep, the periodical sonication leads to higher deformation values. To catch the phenomenon of ultrasound-assisted creep, we extend the flow rule equation by a term that accounts for the process occurring on the microlevel of material induced by ultrasound.

Universal rules of life: metabolic rates, biological times and the equal fitness paradigm

Here we review and extend the equal fitness paradigm (EFP) as an important step in developing and testing a synthetic theory of ecology and evolution based on energy and metabolism. The EFP states that all organisms are equally fit at steady state, because they allocate the same quantity of energy, ~22.4 kJ/g/generation to production of offspring. On the one hand, the EFP may seem tautological, because equal fitness is necessary for the origin and persistence of biodiversity. On the other hand, the EFP reflects universal laws of life: how biological metabolism – the uptake, transformation and allocation of energy – links ecological and evolutionary patterns and processes across levels of organization from: i) structure and function of individual organisms, ii) life history and dynamics of populations, iii) interactions and coevolution of species in ecosystems. The physics and biology of metabolism have facilitated the evolution of millions of species with idiosyncratic anatomy, physiology, behavior and ecology but also with many shared traits and tradeoffs that reflect the single origin and universal rules of life.

Ultrasound-assisted creep deformation of metals

This paper aims to develop a mathematical model to calculate the creep deformation of metals in the ultrasonic field. Experimental data recording that acoustic energy leads to an increase of primary and secondary creep has become the impetus for this research. The model is constructed in terms of the synthetic theory of irrecoverable deformation. To catch the phenomena caused by sonication, we introduce a new term reflecting the nucleation and development of the crystalline grid's defects in the ultrasonic field. By inserting this term into the basic relationships of the synthetic theory that define the deformation state of the material, we have derived the formulae describing the development of time-dependent deformation coupled with ultrasound. As a result, since the analytic solutions fit good the experimental data, we have elaborated an analytical instrument to predict the increase in the creep deformation of metals due to acoustic energy.

Natural selection and circular pathways to seasonal migration in birds

The “migratory revolutions” (MR) model is a synthetic theory of bird migration that seeks to explain the full range of the functional phenotype, from sedentary residents of non-seasonal (tropical) habitats to obligate long-distance migrants, as a cumulative evolutionary response to shifting distributions of adult extrinsic mortality across the annual cycle. At macroevolutionary scales, the general model predicts that migration evolves in circular patterns, reframing classic debates about the effects of migration on speciation and extinction rates. Here, I describe and apply the MR model to a well-known system, the passerine genus Catharus (Turdidae), to illustrate its broad implications for reconstructing evolutionary history.

Universal rules of life: metabolic rates, biological times and the equal fitness paradigm

Here we develop and extend the equal fitness paradigm (EFP) of (Brown et al. 2018) as an important step in developing and testing a synthetic theory of ecology and evolution based on energy and metabolism. The EFP states that all species are equally fit at steady state, because all species allocate the same quantity of energy, ∼22.4 kJ/g/generation to production of offspring. On the one hand, the EFP may seem tautological, because equal fitness across species is necessary for the origin and persistence of biodiversity. On the other hand, the EFP reflects universal laws of life: how biological metabolism – the uptake, transformation and allocation of energy – links ecological and evolutionary patterns and processes across levels of organization: from the structure and function of individual organisms, to the life history and dynamics of populations, to the coevolution of species in ecosystems. The physics and biology of metabolism have simultaneously facilitated the origin and maintenance of enormous biodiversity, so that the millions of species have idiosyncratic features of anatomy, physiology, behavior and ecology. However, there are universal constraints on biodiversity, so that all species share common features of metabolism that reflect the single origin and universal biophysical constraints of life.
