Two distinct regimes of strain rate sensitivity on yield strength are found in a high-strength nantwinned *** yield strength increases from 1410 to 1776 MPa when the strain rate increases from 10–3 to 1400 *** is proposed from the measured small activation volume that the yielding of the nanotwinned steel at higher strain rates is governed by the dislocation bowing out from the carbon *** lower strain rates,however,the yielding is controlled by the continuous re-pinning of dislocations due to the fast diffused carbon atoms,which leads to the relative insensitivity of yield strength to the strain rate.

We report a detailed study of polarization characteristics and subpulse drifting in PSR J1110-5637 with the observations of the Parkes 64 m radio telescope at 1369 *** observations revealed that the trailing component of the pulse profile has obvious subpulse drifting,while the leading component has no subpulse *** the two-dimensional fluctuation spectrum(2DFS),we detected three distinct emission modes in the trailing component(modes A,B and C).The emission in mode A is chaotic and indistinguishable,while modes B and C have obvious subpulse *** vertical modulation periods P3of modes B and C are around the mean values of 12 P and 8 P,*** subpulse drifting of PSR J1110-5637 will expand the pulsar sample with multiple subpulse drifting rates,and this will help future systematic studies on the physical origin of the subpulse drifting phenomenon.

Industries such as aviation and nuclear power have greatly improved their safety performance through the application of human factors methods to the design, development, selection and deployment of a range of technologies and work processes. Health care safety performance generally lags behind these industries and would benefit from a similar application of human factors methods. Clinical engineers are in an ideal position to acquire and apply this human factors knowledge, and lead its adoption in health care. This paper describes a text that has been written specifically for clinical engineers and others who design, develop, select and support the use of health care technologies, to enable them to learn the key methods of human factors and adopt them as part of their ongoing work. Early indications are that these approaches help to ensure that health care technologies are used more safely and effectively, and it is hoped that large-scale adoption will result in a noticeable and worthwhile improvement in overall health care safety. The described text is now ready and has been published in English on the IFMBE website. It is available as a free download in PDF format. Clinical engineers and others working around the world in the area of health technology are encouraged to learn and adopt these methods, and use them as appropriate in their local setting. At time of writing, plans are underway for a translation of this book into Spanish. Once completed, this version will also be made available online at no charge. The authors encourage readers to contact them with their experiences, and the aim is to build a worldwide community that gradually adopts these methods and helps to drive safety improvements in health care.

The dual challenges of global climate change and population growth have increased demand for higher crop yields per unit area. The innovative technology of smart agriculture aims to synergize breeding, cultivation, and production through the application of biological and informatics technologies. Historically, the “Green Revolution” introduced semidwarf varieties of certain key crops by utilizing mutations affecting gibberellin pathways, which significantly increased planting densities and yields.

During the boreal summer,intraseasonal oscillations exhibit significant interannual variations in intensity over two key regions:the central-western equatorial Pacific(5°S-5°N,150°E-150°W)and the subtropical Northwestern Pacific(10°-20°N,130°E-175°W).The former is well-documented and considered to be influenced by the ENSO,while the latter has received comparatively less attention and is likely influenced by the Pacific Meridional Mode(PMM),as suggested by partial correlation analysis *** elucidate the physical processes responsible for the enhanced(weakened)intraseasonal convection over the subtropical northwestern Pacific during warm(cold)PMM years,the authors employed a moisture budget *** findings reveal that during warm PMM years,there is an increase in summer-mean moisture over the subtropical northwestern *** increase interacts with intensified vertical motion perturbations in the region,leading to greater vertical moisture advection in the lower troposphere and consequently resulting in convective *** a process is pivotal in amplifying intraseasonal convection *** observational findings were further verified by model experiments forced by PMM-like sea surface temperature patterns.
