得益于卡雷尔证明了“ 切除双肾后，仅靠移植单侧肾脏就可以挽救生命 ”，人们意识到，捐献者只需捐献一半的肾脏便可以挽救生命，这也为后来的活体肾脏移植埋下了伏笔。

Accepting this suggests that optics offers no new computational capability. To be useful, the best that optics can do is to accomplish the same goals as digital electronics, but in a more ...

Fiber optic transmitters convert electrical signals into optical signals and then inject these optical signals into light-conducting cable. They use light emitting diodes (LED) or laser diodes as ...

This textbook has now been replaced with a newer edition. On 1st July 2025 it will be withdrawn from institutional access further information is available here. This will not affect customers who have ...

Fiber optic couplers are optical devices that connect three or more fiber ends, dividing one input between two or more outputs, or combining two or more inputs into one output. The device allows the ...

Urinary tract infections (UTIs) are very common. A 2022 analysis found that more than 404.6 million people worldwide had UTIs in 2019. UTIs happen when bacteria from the skin or rectum enter the ...

two Bushnell LRHSi 4.5-18×44 and a Tract Toric HD 4-20×50. While these are, respectively, 40-60% less in cost than the same ...

Most urinary tract infections (UTIs) are caused by the E. coli bacteria, which are treated with antibiotics. But some strains may be resistant to common antibiotic types. For the most part ...

One solution could come from a technology called “free-space optics” (FSO), which uses lasers to transfer data through the air. It was pioneered in the 1960s by NASA and for decades has been a ...
