Karnataka Health Minister launches adult BCG vaccination initiative to prevent TB, targeting high-risk groups across 16 districts.

A new BCG vaccination campaign targeting high-risk adults was launched in Bengaluru to coincide with World TB Day, offering free vaccines to the elderly people.

Scientists have developed a compact optical amplifier based on a photonic chip that vastly outperforms traditional optical amplifiers in both bandwidth and efficiency. This breakthrough could reshape ...

盖世汽车讯 现代通信网络依赖光信号来传输大量数据。然而，就像微弱的无线电信号一样，这些光信号需要放大才能在长距离传输中保持信息完整。几十年来，掺铒光纤放大器（EDFA）一直是主流的光信号放大器，它无需频繁再生信号即可实现长距离传输。但其工作频谱带宽有限，制约了光网络的进一步扩展。 图片来源：EPFL 为了满足日益增长的高速数据传输需求，研究人员一直在探索更强大、更灵活且更紧凑的放大器。尽管人工智能 ...

The need for ultra-broadband amplification — amplifiers that work across a wider range of wavelengths — is more pressing than ever. Existing solutions, such as Raman amplifiers, offer some improvement ...
