Background: In the cervical nerve sheath tumor (NST) surgery with dumbbell extension of Eden type 2 or 3, selection of anterior, posterior, or combined approach remains controversial.Objectives: This technical note aimed to Drop Leaf Table propose possible advantages of the posterior unilateral approach (PUA).Methods: Six patients who underwent the

This paper shows the differences in luminous fluxes of two distinguishing dual-layer remote phosphor structures, Flat Dual-Remote Phosphor (FDRP) and Concave Dual-Remote Phosphor (CDRP).The impact of the distance between the two phosphor layers (d_1) and the distance from the phosphor layer to the LED surface (d_2) on the optical properties of the

With the rapid development of wind power, the randomness and volatility of wind power have also caused severe problems of wind power consumption.The phenomenon of wind abandonment is particularly prominent in the "three north" areas.The environmental protection and controllability of regenerative electric heating provide a way for wind absorption a
