A positioning grid is a key clamping structure for fixing the transverse and axial positions of fuel assemblies in nuclear reactors, and it is generally prepared by the transverse stamping of a Zr-4 sheet.However, the texture formed in the processing process of Zr-4 sheets can affect formability, resulting in cracking in the stamping process.Theref
With the development of high-frequency carriers and high-capacity communications, ultrahigh-speed spectrum analyzer based on all-optical methods has been demonstrated in many fields.Limited by current data processing algorithms, ultrahigh-speed spectrum analyzers based on time-lens, such as frequency-domain light intensity spectrum analyzer (f-LISA
The mezquila brooklyn dynamic performance of three slab ballastless tracks in the China Railway Track System (CRTS), which is supported by a simply supported box girder under various train loads, were comprehensively investigated with refined rigid-flexible coupled models.A refined rigid-flexible coupled model of vehicle-multi layer track-bridge sy
The global emergence of multidrug-resistant (MDR) Klebsiella pneumoniae, particularly carbapenem-resistant K.pneumoniae (CRKP), presents a severe public health threat, limiting available treatment options.Tigecycline and eravacycline, have been considered a last-resort therapeutic against MDR Enterobacteriaceae.However, strains were resistant to th
ill tempered gnome Using the quantum field theory methods, we calculate the helicity flip of an electron scattering off protons in dense matter of a neutron star.The influence of the electroweak interaction between electrons and background nucleons on the helicity flip shiro neon zero is examined.We also derive the kinetic equation for the chiral i
