Significance Nature creates the gradient structure (GS) for a purpose: to make biological systems strong and tough survive severe natural forces. For grain-size GS, deformation physics is still unclear. One wonders if GS in nanomicroscale would also benefit materials engineered by mankind. In this paper, universal strain hardening mechanism revealed GS. We discovered unique extra that intrinsic Its presence of together with stress state change. A superior combination strength ductility not...
Manganese-based layer-structured transition metal oxides are considered promising cathode materials for future sodium batteries owing to their high energy density potential and industrial feasibility. The grain-related anisotropy electrode/electrolyte side reactions, however, constrain cycling lifespan, particularly at voltages. Large-sized single-crystal O3-typed Na[Ni0.3Mn0.5Cu0.1Ti0.1]O2 was thus designed successfully synthesized toward high-voltage long-lifespan batteries....
Abstract Conventional metals are routinely hardened by grain refinement or cold working with the expense of their ductility. Recent nanostructuring strategies have attempted to evade this strength versus ductility trade-off, but paradox persists. It has never been possible combine reachable in nanocrystalline large uniform tensile elongation characteristic coarse-grained metals. Here a defect engineering strategy on nanoscale is architected approach ultimate combination. For Nickel,...
Abstract The self-consistent nonlinear interaction of drift wave (DW) and zonal flow (ZF) is investigated
using gyrokinetic theory, with both spontaneous excitation beat-driven ZF by DW
treated on the same footing. DW solitons are formed in DW-ZF interactions are
confined between radially spaced micro-barriers induced spontaneously excited ZF. resulting
radial structures exhibit similar pattern to E×B“staircase”
observed numerical simulations. These...
Atomistic deformation mechanisms of hierarchically nano-twinned (NT) Ag under shock conditions have been investigated using a series large-scale molecular dynamics simulations. For the same grain size d and spacing primary twins λ1, average flow stress behind front in NT first increases with decreasing secondary λ2, achieving maximum at critical then drops as λ2 decreases further. Above are dominated by three type strengthening mechanisms: (a) partial dislocations emitted from boundaries...
Purpose: The purpose of this study was to summarize the clinical experience laparoscopic percutaneous extraperitoneal closure internal ring using an epidural needle for treatment inguinal hernias. Methods: There were 1,142 children with isolated hernia who participated in from January 2013 May 2018. An used treat indirect assistance. Symptoms and signs followed up at 1 week, 3 months, every 1-2 years after operation. Results: All underwent surgery successfully. patients discharged days...
The purpose of this study was to summarize our clinical experience with transscrotal transverse incision in the treatment low and middle cryptorchidism children.A total 796 children or participated from March 2012 May 2018. Transscrotal used treat cryptorchidism. Symptoms signs were followed up at 1 week, month, 3months every six 12 months thereafter.Testicular descent fixation through scrotal successfully performed all children. All patients discharged 1-2 days after operation. During...
Rationally fixing operation optimization target values of fossil fired power plants is the basis and key for effectuating performance evaluation optimization. Actual states sets can often not be correctly real-time reflected by determined with traditional methods. A way establishing optimized systems proposed applying data mining technique making full use large amount historical stored in plants. The plant's found fuzzy association rule algorithm. It established employing method to optimal...
This study was performed to summarize our clinical experience with testicular descent and fixation through a scrotal stria incision for the treatment of palpable cryptorchidism in children. included 1034 children from March 2009 2019. A used perform fixation. Overall, 1020 successfully underwent surgical incision, 14 patients conversion inguinal surgery. All were discharged 1–2 days after operation. During hospitalization follow-up, 55 developed complications, including 10 retraction, 7 poor...
Based on the engineering geological data of a nuclear power plant site, nine profiles were created with hard interlayers different thicknesses. The equivalent linearization method seismic motion segment‐input used for one‐dimensional nonlinear response analysis was applied to study effect interlayer thickness peak acceleration and spectra site response. results showed that there an obvious influence responses. With increase thickness, responses decreased. Under same interlayer, strengthened...
Internal-external coupled full-scale modeling for a rectangular-to-elliptical shape-transition (REST) scramjet under high flight Mach number of 12 was modeled by Improved Delayed Detached Eddy Simulation (IDDES) and Dynamic Zone Flamelet combustion Model (DZFM).

The self-consistent nonlinear interaction of drift wave (DW) and zonal flow (ZF) is investigated using gyrokinetic theory, with both spontaneous excitation beat-driven ZF by DW treated on the same footing. solitons are formed in DW-ZF interactions confined between radially spaced micro-barriers. resulting radial structures exhibit similar pattern to ExB "staircase" observed numerical simulations. These micro-barriers generated repulsive response due spontaneously excited ZF, which, as a...
