Large intelligent surface (LIS) is a technology that extends massive MIMO by considering an even greater number of antennas distributed throughout vast areas. In order to be able to implement this technology, it is crucial to consider decentralized architectures so as to make the whole system scalable. We consider a LIS divided into several LIS panels of smaller size, which can be located far away

This piece is influenced by the Bénard instability, a puzzle of stability that occurs far from equilibrium. Regarded as a classic case of self-organization, Henri Bénard discovered that heating a thin layer of fluid may result in strangely ordered forms. When a liquid is uniformly heated from below, a constant circuit is set into motion moving from bottom to top. When the temperature difference be

The Transformer architecture has been successful across many domains, including natural language processing, computer vision and speech recognition. In keyword spotting, self-attention has primarily been used on top of convolutional or recurrent encoders. We investigate a range of ways to adapt the Transformer architecture to keyword spotting and introduce the Keyword Transformer (KWT), a fully se

Reconfigurable scan networks (RSNs), like IEEE Std. 1687 networks, offer flexible and scalable access to embedded (on- chip) instruments. These networks are typically accessed from the outside via a dedicated test port, like the test access port (TAP) of IEEE Std. 1149.1. As not all integrated circuits have a dedicated test port, the IEEE Std. P1687.1 working group is exploring how existing functi

This paper is a theoretical contribution to interrogate and elucidate a term commonly used (but rarely interrogated) from the perspective of the economic geography field within which we work: peripheries. As researchers of “peripheries” we are all too familiar with the fuzziness and problematic nature of this term, and our long-standing research agenda is to work towards clarifying and nuancing it

Given a network of receivers and transmitters, the process of determining their positions from measured pseudoranges is known as network self-calibration. In this paper we consider 2D networks with synchronized receivers but unsynchronized transmitters and the corresponding calibration techniques, known as Time-Difference-Of-Arrival (TDOA) techniques. Despite previous work, TDOA self-calibration i

In this study, we revisit the factor analytical (FA) approach for (near unit root) dynamic panel data models, whose asymptotic distribution has been shown to be normal and well centered at zero without the need for valid instruments or correction for bias. It is therefore very appealing. The question is: Does the appeal of FA, which so far has only been documented for fixed effects panels, extends
