Toward End-to-End, Full-Stack 6G Terahertz Networks

Recent evolutions in semiconductors have brought the terahertz band in the spotlight as an enabler for terabit-per-second communications in 6G networks. Most of the research so far, however, has focused on understanding the physics of terahertz devices, circuitry and propagation, and on studying physical layer solutions. However, integrating this technology in complex mobile networks requires a proper design of the full communication stack, to address link- and system-level challenges related to network setup, management, coordination, energy efficiency, and end-to-end connectivity. This paper provides an overview of the issues that need to be overcome to introduce the terahertz spectrum in mobile networks, from a MAC, network and transport layer perspective, with considerations on the performance of end-to-end data flows on terahertz connections.Comment: Published on IEEE Communications Magazine, THz Communications: A Catalyst for the Wireless Future, 7 pages, 6 figure

The Gendering of Space: Female Strollers on the Market in 19th and 20th Century New York

This essay aims to shed some light on the concept of urban walking or, using its literary definition, flânerie in New York City at the dawn of the 20th century. This study specifically focuses on female strollers walking New York at the turn of the century as strollers on the market, faithfully representing America’s social changes as the birth of women’s emancipation. In doing so, this essay will analyse a case study based on the comparison of two novels representing two examples of female strollers in American fiction, strolling through the streets of New York City. The ultimate aim of this study is to prove that the female flâneuse at the turn of the century walks both as a social signifier and as a symbol of a collective psychology, tracing the history of New York City and representing the salient moments in American cultural history. The study compares Edith Wharton’s The House of Mirth and Stephen Crane’s Maggie: A Girl of the Streets. Their representations of female strollers, similar and yet different, will help us understand this figure, providing us with the tools necessary to trace part of America’s history and the history of New York City as filtered through the eyes of the flâneu

Racial uplift in speculative fiction: technological empowerment and the enforcement of black identity in Colson Whitehead’s 'The Intuitionist' and 'John Henry Days'

Following the steps of technological innovation in the US, one can easily notice how technology and its use has been inaccurately and stereotypically reduced to an exclusivism related to a white-Western ideal. However, black speculative fiction has often tried to overtake this concern. In light of this, the aim of this contribution is to examine the relationship between black identity and technology through the lens of speculative fiction, in Colson Whitehead’s The Intuitionist and John Henry Days. The final goal is to demonstrate how Whitehead uses technology as a trope to reinforce or rather empower black identity in what will be eventually defined as a form of “racial uplift,” an enforcement of blackness that elevates the African-American putting him in a position of competence and control toward the machine. Delving into the stereotype of technology as a form of racism toward the black community, by way of conclusion the essay considers Whitehead as an “uplift writer” for his illustration ofc technology as a narrative tool that lifts black identity by subverting the discriminative and racist encodement of African-Americans within technological development
