In a short observation time, after the range alignment and phase adjustment, the motion of a target can be approximated as a uniform rotation.The radar observing process can be simply described as multiplying an observation matrix on the ISAR image, which can be thought of as a linear system.It is known that the longer observation time is, the high
Rapid cell growth demands fast protein translational elongation to alleviate ribosome shortage.However, speedy elongation undermines translational accuracy because of a mechanistic tradeoff.Here we provide genomic evidence in budding yeast and mouse Gin Glasses embryonic stem cells that the efficiency-accuracy conflict is alleviated by slowing down
A 70-year-old woman presented to our emergency center with a complaint of jerking and twisting movements in her left upper limb and left ankle with deviation of her mouth toward the left.The movements had lasted two minutes and the deviation resolved spontaneously after 30 minutes.She had a history of similar movements five days earlier.During her
The face gear is a crossed gear similar to a hypoid gear.Owing to its compactness and good assemblability, it is used in geared motors and transmissions for helicopters.Studies on various aspects such as design, processing, and tooth modification methods have been conducted for face gears, which are typically used in fishing reels as spinning reels
Radiotherapy and chemotherapy are effective treatments for patients with locally advanced rectal cancer (LARC) and can significantly improve the likelihood of R0 resection.Radiotherapy can be used as a local treatment to reduce the size of the tumor, improve the success rate of surgery and reduce the residual cancer cells after surgery.Early chemot
