Spreading in claw-free cubic graphs [PDF]
Opuscula MathematicaLet \(p \in \mathbb{N}\) and \(q \in \mathbb{N} \cup \lbrace \infty \rbrace\). We study a dynamic coloring of the vertices of a graph \(G\) that starts with an initial subset \(S\) of blue vertices, with all remaining vertices colored white.

Slow Forcing in the Projective Dynamics Method
, 1998 We provide a proof that when there is no forcing the recently introduced projective dynamics Monte Carlo algorithm gives the exact lifetime of the metastable state, within statistical uncertainties.

Prior Zero Forcing for Cognitive Relaying
IEEE Transactions on Wireless Communications, 2013 Relaying primary signals by cognitive base-stations (CBSs) can help the primary system and thus win CBSs a higher chance to transmit their own signals. For this purpose, conventional zero-forcing (CZF) beamforming is a straightforward solution where the primary and cognitive signals are transmitted from a multi-antenna CBS without causing interference ...

Equalization-Based Beamforming for Secure Multicasting in Multicast Wiretap Channels
IEEE Access, 2021 In this paper, a beamforming scheme is proposed to maximize a secrecy multicast rate (SMR) in the multicast wiretap channel, in which the multiple unauthorized users overhear the multicast messages.

Partial Zero-Forcing for Multi-Way Relay Networks
, 2018 The ever increasing demands for mobile network access have resulted in a significant increase in bandwidth usage. By improving the system spectral efficiency, multi-way relay networks (MWRNs) provide promising approaches to address this challenge.

FEBS Letters, EarlyView.The Ile181Asn variant of human UDP‐xylose synthase (hUXS1), associated with a short‐stature genetic syndrome, has previously been reported as inactive. Our findings demonstrate that Ile181Asn‐hUXS1 retains catalytic activity similar to the wild‐type but exhibits reduced stability, a looser oligomeric state, and an increased tendency to precipitate ...

Uplink Sum Rate Analysis of Massive Distributed MIMO Systems Over Composite Fading Channels
IEEE Access, 2018 As the number of antennas goes large in the massive multiple-input multiple-output (MIMO) scenario, the large-scale fading plays an increasingly important role in the system performance.

Rate-Maximizing Zero-Forcing Hybrid Precoder for MU-MISO-OFDM
IEEE Access, 2023 Hybrid precoders, consisting of an analog hardware-constrained part operating at radio frequency (RF) and a digital part operating at baseband, reduce the RF implementation complexity and power consumption of multi-antenna transceivers, at the expense of

Minimum rank and zero forcing number for butterfly networks
, 2018 The minimum rank of a simple graph $G$ is the smallest possible rank over all symmetric real matrices $A$ whose nonzero off-diagonal entries correspond to the edges of $G$.
