Multiple subglacial water bodies below the south pole of Mars unveiled by new MARSIS data
Sebastian Emanuel Lauro, Elena Pettinelli, Graziella Caprarelli +10
The detection of liquid water by the Mars Advanced Radar for Subsurface and Ionosphere Sounding (MARSIS) at the base of the south polar layered deposits in Ultimi Scopuli has reinv…
Grant-Free Access via Bilinear Inference for Cell-Free MIMO with Low-Coherent Pilots
Hiroki Iimori, Takumi Takahashi, Koji Ishibashi +2
We propose a novel joint activity, channel, and data estimation (JACDE) scheme for cell-free multiple-input multiple-output (MIMO) systems compliant with fifth-generation (5G) new…
Full-Duplex MIMO Systems with Hardware Limitations and Imperfect Channel Estimation
Hiroki Iimori, Giuseppe Thadeu Freitas de Abreu, Koji Ishibashi
We consider a bidirectional in-band full-duplex (FD) multiple-input multiple-output (MIMO) system subject to imperfect channel state information (CSI), hardware distortion, and lim…
Discrete-Aware Matrix Completion via Proximal Gradient
Hiroki Iimori, Giuseppe Thadeu Freitas de Abreu, Omid Taghizadeh +1
We present a novel algorithm for the completion of low-rank matrices whose entries are limited to a finite discrete alphabet. The proposed method is based on the recently-emerged p…
A Robot by Any Other Frame: Framing and Behaviour Influence Mind Perception in Virtual but not Real-World Environments
Sebastian Wallkotter, Rebecca Stower, Arvid Kappas +1
Mind perception in robots has been an understudied construct in human-robot interaction (HRI) compared to similar concepts such as anthropomorphism and the intentional stance. In a…
