A Survey on Radio over Fiber (RoF) for Wireless Broadband Access Technologies [PDF]

International Journal of Computer Applications, 2013
this paper presents a survey on RoF for Wireless Broadband Access technology like WiMAX (Fixed and Mobile). RoF is considered to achieve an effective delivery of wireless and baseband signal, and it also reduces the power consumption. In the other hand WiMAX (Worldwide Interoperability for Microwave Access) is recent fast growing broadband access ...

Naked‐Eye Visual Warning of ppmv‐Level Fault‐Free Humidity Upper Limit

Advanced Science, Volume 13, Issue 14, 9 March 2026.
In this study, based on the urgent need in many critical fields for ppmv‐level fault‐free humidity upper limit (ppmv‐FFHUL) monitoring, an innovative threshold gated humidity sensing technology was developed. It exhibits superior portability (as thin and light as paper) and highly economic feature (without auxiliary instruments at all), and can achieve

M2 Macrophages are Major Mediators of Germline Risk of Endometriosis and Explain Pleiotropy With Comorbid Traits

Advanced Science, Volume 12, Issue 41, November 6, 2025.
Genes associated with endometriosis risk are highly expressed in M2 macrophages, particularly ligands IL1A and IL1B. Endometrial‐type epithelium and stroma are likely recipients of these ligands. While IL1B treatment disturbs epithelial organization, blockage of the signaling results in a dose‐dependent decrease in spontanesous and evoked pain, reduces
