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 ...

Tellus: Series A, Dynamic Meteorology and Oceanography, 2022 This paper considers a dynamical system described by a multidimensional state vector x. A component 'x' of x evolves according to 'dx/dt = f'(x). Equilibrium fluctuations are fluctuations of an equilibrium solution x('t') obtained when the system is in ...

Calpain small subunit homodimerization is robust and calcium‐independent
FEBS Letters, EarlyView.Calpains dimerize via penta‐EF‐hand (PEF) domains. Using single‐molecule force spectroscopy, we measured the strength and kinetics of PEF–PEF homodimer binding. The interaction is robust, shows a transient conformational step before dissociation, and remains largely insensitive to Ca2+.

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.

The ubiquitin‐proteasome system and autophagy as guardians of the cellular proteome
FEBS Letters, EarlyView.This Perspective covers the three principles governing the crosstalk between the ubiquitin‐proteasome system and autophagy in cellular proteostasis: (1) a shared ubiquitin code routing substrates via shuttle factors or autophagy receptors; (2) spatial compartmentalization into phase‐separated degradation hubs and organelle‐specific modules (exemplified

Failed Skew Zero Forcing Numbers of Path Powers and Circulant Graphs
AppliedMathFor a graph G, the zero forcing number of G, Z(G), is defined to be the minimum cardinality of a set S of vertices for which repeated applications of the forcing rule results in all vertices being in S. The forcing rule is as follows: if a vertex v is in

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.

Zero-Forcing Precoding and Generalized Inverses [PDF]
IEEE Transactions on Signal Processing, 2008 We consider the problem of linear zero-forcing precoding design and discuss its relation to the theory of generalized inverses in linear algebra. Special attention is given to a specific generalized inverse known as the pseudo-inverse. We begin with the standard design under the assumption of a total power constraint and prove that precoders based on ...

FEBS Letters, EarlyView.The physical dimensions and shape of bacterial cells define the surface area available to acquire nutrients and the volume available for synthesizing proteins and DNA. Here, we use computational systems biology to decode the importance of cell geometry as a major determinant of prokaryotic phenotype, including growth rate and metabolic efficiency. This
