Exploiting multiple antennas for synchronization [PDF]

open access: yes, 2009
Orthogonal frequency-division multiplex (OFDM) offers a low-complexity solution to equalization in multipath channels but does so by increasing the symbol period.

A novel fixed-time smooth synchronization controller for stabilizing chaotic spacecraft formation

open access: yesAlexandria Engineering Journal
This article addresses two essential gaps in chaos synchronization. First, it studies fixed-time leader-follower spacecraft formation (LFSF) synchronization of multiple chaotic spacecraft systems, a previously unexplored area.

Finite-/fixed-time synchronization of delayed Clifford-valued recurrent neural networks

open access: yesAdvances in Difference Equations, 2021
This paper investigates the problem of finite-/fixed-time synchronization for Clifford-valued recurrent neural networks with time-varying delays. The considered Clifford-valued drive and response system models are firstly decomposed into real-valued ...

Fixed-time synchronization of semi-Markovian jumping neural networks with time-varying delays

open access: yesAdvances in Difference Equations, 2018
This paper is concerned with the global fixed-time synchronization issue for semi-Markovian jumping neural networks with time-varying delays. A novel state-feedback controller, which includes integral terms and time-varying delay terms, is designed to ...

Ligand‐dependent transcriptional heterogeneity in cell cycle gene expression delays G1/S entry

open access: yesFEBS Letters, EarlyView.
EGF and HRG induce distinct G1/S progression programs in ErbB2‐amplified BT474 breast cancer cells. Despite activating the potent ErbB2–ErbB3 heterodimer, HRG does not accelerate cell‐cycle entry. Instead, EGF promotes earlier restriction‐point passage via ERK–FOS signaling, whereas HRG activates the AKT–MYC axis, driving transcriptional heterogeneity ...

Membrane composition and thermodynamic identity as boundaries of life for synthetic cell research

open access: yesFEBS Letters, EarlyView.
What makes a cell a cell? The boundary of a living cell is not just a wall. Read as a Markov blanket, the membrane separates internal from external states, generating identity and non‐equilibrium order. Can this identity be rebuilt from scratch in a synthetic cell?

Fixed/Preassigned-Time Synchronization of Fully Quaternion-Valued Cohen–Grossberg Neural Networks with Generalized Time Delay

open access: yesMathematics, 2023
This article is concerned with fixed-time synchronization and preassigned-time synchronization of Cohen–Grossberg quaternion-valued neural networks with discontinuous activation functions and generalized time-varying delays.

Reproduction biotechnology in buffaloes: optimization of synchronization protocol for target breeding [PDF]

open access: yes, 2013
The achievement of early cyclicity after calving is of vital importance in maintaining a dairy industry. Post-partum anoestrous in buffalo is a major cause of long calving interval and infertility resulting in economic loss to buffalo breeders.

Hijacking emergency granulopoiesis: Neutrophil ontogeny and reprogramming in cancer

open access: yesMolecular Oncology, EarlyView.
Neutrophils are highly plastic innate immune cells; their functions in cancer extend beyond the tumour microenvironment. This Review summarises current understanding of neutrophil maturation and heterogeneity and highlights tumour‐induced granulopoiesis as a systemic programme that expands immature, immunosuppressive neutrophils via tumour‐derived ...
