Deterministic Massively Parallel Connectivity [PDF]
SIAM Journal on Computing, 2022 We consider the problem of designing fundamental graph algorithms on the model of Massive Parallel Computation (MPC). The input to the problem is an undirected graph $G$ with $n$ vertices and $m$ edges, and with $D$ being the maximum diameter of any connected component in $G$.

Massive haemoptysis: an unusual connection [PDF]
Thorax, 2021 A 60-year-old man presented with a 4-day history of small volume haemoptysis. His medical history revealed a pericardiectomy with pericardial window creation for severe constrictive pericarditis secondary to seropositive rheumatoid arthritis in 1997 and pulmonary tuberculosis aged 7, with a treated recurrence in 2005.

Distributed Optimization for Massive Connectivity [PDF]
IEEE Wireless Communications Letters, 2020 Massive device connectivity in Internet of Thing (IoT) networks with sporadic traffic poses significant communication challenges. To overcome this challenge, the serving base station is required to detect the active devices and estimate the corresponding channel state information during each coherence block.

Toward Massive Connectivity for IoT in Mixed-ADC Distributed Massive MIMO [PDF]
IEEE Internet of Things Journal, 2020 Massive connectivity is a key requirement for the Internet of Things (IoT). In practice, the network should be capable of accommodating thousands of devices and meeting their traffic demands. In this article, we consider the access phase for IoT in a mixed-analog-to-digital converter distributed massive multiple-input–multiple-output system, in which ...

Reconfigurable Intelligent Surface for Massive Connectivity
CoRR, 2021 With the rapid development of Internet of Things (IoT), massive machine-type communication has become a promising application scenario, where a large number of devices transmit sporadically to a base station (BS). Reconfigurable intelligent surface (RIS) has been recently proposed as an innovative new technology to achieve energy efficiency and ...

Sparse Activity Detection for Massive Connectivity [PDF]
IEEE Transactions on Signal Processing, 2018 This paper considers the massive connectivity application in which a large number of potential devices communicate with a base-station (BS) in a sporadic fashion. The detection of device activity pattern together with the estimation of the channel are central problems in such a scenario.

Financial Simulations On a Massively Parallel Connection Machine [PDF]
The International Journal of Supercomputing Applications, 1991 The valuation of complex financial instruments that ap pear in the banking and insurance industries requires simulations of their cashflow behavior in a volatile in terest rate environment. These simulations are complex and computationally intensive. Their use, thus far, has been limited to intra-day analysis and planning.
