Due to its heavy reliance on fossil fuels and rapid urbanization, China's economic growth is accompanied by environmental problems. Hence, it is vital to solve the issue by promoting green growth and finding factors to boost it. The current study presents FinTech as a factor enhancing green growth in China through the mediation effect of the energy transition. The green growth index is created through a comprehensive literature review and selecting the most critical indicators. It has been established through benchmark regression that FinTech positively affects green growth in China. However, results also prove that the energy transition is the path through which FinTech affects green growth. Policymakers are advised to direct their efforts toward the energy transition and FinTech to solve the problems related to China's rapid economic growth., Competing Interests: The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (© 2024 The Authors.

Fifth generation (5G) communication systems deploy a massive MIMO technique to enhance gain and spatial multiplexing in arrays of 16 to 128 antennas. In these arrays, it is critical to isolate the adjacent antennas to prevent unwanted interaction between them. Fifth generation absorbers, in this regard, are the recent interest of many researchers nowadays. The authors present a dual-band novel metamaterial-based 5G absorber. The absorber operates at 24 GHz and 28 GHz and is composed of symmetric meander lines connected through a transmission line. An analytical model used to calculate the total number of required meander lines to design the absorber is delineated. The analytical model is based on the total inductance offered by the meander line structure in an impedance-matched electronic circuit. The proposed absorber works on the principal of resonance and absorbs two 5G bands (24 GHz and 28 GHz). A complete angular stability analysis was carried out prior to experiments for both transverse electric (TE) and transverse magnetic (TM) polarizations. Further, the resonance conditions are altered by changing the substrate thickness and incidence angle of the incident fields to demonstrate the functionality of the absorber. The comparison between simulated and measured results shows that such an absorber would be a strong candidate for the absorption in millimetre-wave array antennas, where elements are placed in proximity within compact 5G devices.

A knowledge, attitude and practice survey of acquired Immune Deficiency Syndrome (AIDS) was conducted among 805 paramedics at a tertiary care hospital in Islamabad in mid 1993. The mean age of the study population was 29.0 +/- 7.2 years and 59% were males. Almost 25% individuals either had no or upto primary level education. Initial response of 10% subjects was not having heard of AIDS and 70% thought their knowledge was sketchy, while 43% could not mention any cause for the disease. Almost 50% did not know that HIV infection could be asymptomatic. With respect to attitudes about AIDS, 30% subjects thought that changing life style shall have no effect on avoiding AIDS, 50% were of the view that at present AIDS did not pose a significant threat to them and 4% individuals however, admitted to having risk of contracting the disease. There existed significant gaps in the knowledge and attitudes of paramedical staff about AIDS and correlated with the level of education of the staff. These deficiencies need to be addressed through developing health education packages in local languages, targeted especially towards paramedical staff.
