This article proposes an adaptive vehicular antenna array with four analog variable phase shifters and a corporate feed network to tilt the main beam in any broadside direction and scan the blind spot zone. Square modified cantor fractal geometry of each element achieves 65% surface reduction, measured 75 MHz bandwidth, 5.5 dB gain, −32 dB return loss, and an array gain of 11 dB at 5.88 GHz dedicated short range communication service frequency band. © 2015 Wiley Periodicals, Inc.

The world is facing a new geopolitical challenge in the pandemic caused by the spread of COVID-19. The world economy has shrunk by about 3%. The trade war between the United States and China and their defensive agreements with other countries was already a huge problem, but it has reached a critical stage due to COVID-19. The United States has filed multiple lawsuits against China, alleging that they purposely released the Coronavirus. The objective of this article is to examine the shifting Geopolitics, focusing on international economic and defensive relationships among countries, and especially on the Second Cold War between the United States and China. In this pandemic situation, more countries are facing economic downturn and loss of human life. A new geopolitical journey has been started, which is based on the availability of Personal Protective Equipment (PPE) and medical products. All previous problems that had not yet been solved by the United Nations have become fresh challenges. Another big challenge is the demise of Neoliberalism in the world. Bureaucratic wars have started in the interregional and intraregional zones, and the Second Cold War has started between the United States and China. A major finding of this article is the significant correlation between the death rate of different countries and the shift of geopolitics to a critical stage.

The production of the early Buddhist texts had a significant purpose of treasuring the teachings of the Buddha. The texts were in oral form and developed over a long time span. The period of composition and compilation of the texts witnessed magnanimous changes in terms of historical evolution and socio-political development in India. Several ethical principles in the form of the Buddha’s teachings made Buddhism popular heretical sect of the sixth century BCE. Buddhism propagated against the complex Vedic ritual practices but in no way tried to reform the Vedic structural framework. If carefully studied, the Buddhist ethos reveal an all pervasive attempt to create a resolution to the conflicts of the conventional society This becomes clear in light of many instances depicted in the early Buddhist texts. In this article, I would interrogate the role played by ‘social status’ in negotiating marriages and how that has been represented in the Jᾱtakas, Therīgāthā and Theragᾱthᾱ. How nuptial ties has been dealt in the Buddhist texts is significant because the description of the rituals which forms the central aspect in the occasion of the marriage between two individuals has been completely absent in the Buddhist textual narratives. Whereas most of the narratives in the Jᾱtakas are based on the description of householder’s life, the nuptial ties and complexities developed out of it. This article maps a comparative analysis of the Jᾱtakas, Therīgāthā and Theragᾱthᾱ for a better understanding of our shared past.
