    Brain-Mind-Body Practice and Health (2021)
    Frontiers Media SA
    Details
    Publication Date: 2024-03-29
    Description: It is acknowledged that practice could induce rapid change or reorganization of the brain’s cellular or neural networks as well as behaviors. Notably, practice relevant to mental or physical approach attracted great attention in this decade. It highlights profound significance both for human evolvement and individual development. Specifically, acquiring fine motor skills is a crucial premise for human being to evolve to modern human by using tools in one side. In the other side, numerous evidences indicated that motor learning involved in limb and trunks promotes the development of individual brain in anatomy and functions. Hence, motor learning is also tightly associated with developmental plasticity. These studies on brain-mind-body practice illuminate a promising way in promoting human brain health. This editorial covers wide range of brain-mind-body practice forms to summarize recent new findings and development from behavioral, physiological, neurobiological and psychological science approaches. In this research topic, we addressed recent findings from theoretical as well as experimental perspective including contributions under the following three headings: 1) intervention studies to investigate the positive effect of brain-mind-body practice on cognition and relevant brain mechanism. The intervention pattern consisted of short-term practice ranging from few hours to several weeks; 2) cross-sectional studies using expert-novice paradigm to explore the behavioral and neural system change induced by extensive brain-mind-body practice; 3) the mediators influence the relationship between practice and health outcomes and 4) new viewpoints on brain-mind-body practice from theoretical perspectives. Here we briefly highlight these articles aiming to provide a deep understanding for the association between practice, plasticity and health for readers. Additionally, it offers new insights for developing possible practice interventions for clinical treatment of neurological dysfunction or disorders.

    Influence of Turning by Burnishing on Surface Integrity to Analyze Feasibility of Hybrid Process (2008)
    s.l. ; Stafa-Zurich, Switzerland

    Notes: Burnishing, an ultra-precision superficial plastic deformation process, is usedincreasingly as a surface enhancement finishing treatment after machining operations not only togive a mirror-like and work-hardened surface but also to impose favorable compressive residualstress in it. To analyze the feasibility of turning-burnishing hybrid process, the Taguchi’s L27(313)orthogonal array method with the analysis of variance (ANOVA) were used to analyze the influenceof the initial turning process on surface integrity of roller burnished AISI 1045 steel such as surfaceroughness, surface microhardness. three turning parameters, namely the cutting feed, cutting depthand cutting speed, three burnishing parameters, namely the burnishing feed, burnishing depth andburnishing speed were selected as the experimental factors in Taguchi’s design of experiments todetermine which one has the dominant influence and how it works on burnishing effects, namelythe surface roughness and surface microhardness, the interactions between cutting feed, burnishingfeed and burnishing depth were considered. The experimental results agreed well with thetheoretical analysis and the conclusion is cutting feed has dominant influence on burnished surfaceintegrity

    Notes: This paper presents an investigation on the surface roughness of burnished hypereutectic Al-Si alloy ¾ a widely used light-weight and wear resistant material in automobile, electric and aircraft industries. Based on the techniques of Taguchi, an orthogonal experiment plan with the analysis of variance (ANOVA) is performed and a second-order regressive mathematical model is established. Meanwhile, the influence of process parameters on surface roughness and its mechanism are discussed. From the experiments, it is found that burnishing process is effective to decrease surface roughness of hypereutectic Al-Si alloy components, in which, all input parameters have a significant effect on the surface roughness. To achieve a small surface roughness, the optimum process parameters are recommended

    Finite Element Analysis of Effects of Ball Burnishing Parameters on Residual Stresses (2004)

    Notes: A three-dimensional coupled thermal-mechanical model of ball burnishing process isdeveloped using commercial explicit finite element code MSC. Marc. The workpiece is modeled as being elastic-plastic, while its flowstress is taken as a function of strain, strain-rate, and temperature. Temperature-dependent material properties are also considered in this analysis. The burnishing ball is considered as rigid and only heat transfer analysis is carried out for it. In the zone of the workpiece and tool contact, the Coulomb friction is taken into account. Effects of ball burnishing parameters (burnishing force, feed rate, speed, ball diameter and number of tool passes) on residual stresses are analyzed. The results show that burnishing force, ball diameter, number of passes and burnishing feed have the most significant effect on the residual stresses. However, burnishing speed seems to just produce little effect on those. Larger burnishing force, larger number of passes, smaller ball diameter and small feed rate seem to be more effective in increasing in the maximum compressive residual stress and the depth of the layer at the compressive stress state

    Notes: Metal cutting operations constitute a large percentage of the manufacturing activity. One of the most important objectives of metal cutting research is to develop techniques that enable optimal utilization of machine tools, improved production efficiency, high machining accuracy and reduced machine downtime and tooling costs. Machining process condition monitoring is certainly the important monitoring requirement of unintended machining operations. A multi-purpose intelligent tool condition monitoring technique for metal cutting process will be introduced in this paper. The knowledge based intelligent pattern recognition algorithm is mainly composed of a fuzzy feature filter and algebraic neurofuzzy networks. It can carry out the fusion of multi-sensor information to enable the proposed intelligent architecture to recognize the tool condition successfully

    Notes: Iron powders were successfully consolidated by a Pulse Electric Current Sintering(PECS) process in a short heating duration of 6 min. Microstructure and chemical composition of the sintered samples were studied by an optical microscope, scanning electron microscope (SEM) and energy dispersive X-ray spectroscopy (EDX). Experimental results showed that both the densification of powders and inter-diffusion between elements were accelerated by increasing of the pulse peak. No noticeable grain growth was observed in the sintered samples. When the peak ofpulse current increased, the density and transverse rupture strength of the sintered samples were improved

    Notes: A coupled thermo-mechanical model of plane-strain orthogonal metal cutting includingburr formation is presented using the commercial finite element code. A simulation procedure basedon Normalized Cockroft-Latham damage criterion is proposed for the purpose of better understandingthe burr formation mechanism and obtaining a quantitative analysis of burrs at exit. The cuttingprocess is simulated from the transient initial chip formation state to the steady-state of cutting, andthen to tool exit transient chip flow, by incrementally advancing the cutting tool. The effects of cuttingcondition on the non-steady-state chip flow while tool exit can be investigated using the developedfinite element model

    Notes: 2D finite element model with the same material for backup to minimize the burr size wasdeveloped to investigate mechanism of burr formation and burr minimization. The flowstress of theworkpiece and backup material are taken as a function of strain, strain-rate and temperature.Temperature-dependent material properties are also considered. The Cockroft-Latham damagecriterion has been adopted to simulate ductile fracture. The crack initiation and propagation issimulated by deleting the mesh element. The result shows putting a backup material behind the edgeof the workpiece is an effective way to minimize the burr size. The effects of cutting condition,temperature and different backup material properties on the burr formation and burr size can beinvestigated using the developed finite element model. This model could be useful in the search foroptimal tool geometry and cutting condition for burr minimization and for the modeling of a burrformation mechanism
