Survivable and Reliable WDM-PON System With Self-Protected Mechanism Against Fiber Fault

IEEE Access, 2019
In the paper, we present and design a self-restored wavelength multiplexing division passive optical network (WDM-PON) configuration to prevent the fiber failure and data disconnection.

Energy Efficient IoT Virtualization Framework with Passive Optical Access Networks [PDF]

, 2016
In this paper we design a framework for an energy efficient cloud computing platform for Internet of things (IoT) accompanied by a passive optical access network (PON). The design is evaluated using a Mixed Integer Linear Programming (MILP) model.

Nicotinic Receptors in the Medial Habenula to Interpeduncular Nucleus Pathway: Modulators of Reward, Aversion and Emotion

European Journal of Neuroscience, Volume 62, Issue 11, December 2025.
ABSTRACT The medial habenula–interpeduncular nucleus pathway is a highly conserved and densely innervated brain circuit known for its unique cholinergic transmission and exceptional expression of nicotinic acetylcholine receptors. This pathway plays a critical role in regulating motivational and emotional processes, particularly those related to ...

Sleep neuroimaging: Review and future directions

Journal of Sleep Research, Volume 34, Issue 6, December 2025.
Summary Sleep research has evolved considerably since the first sleep electroencephalography recordings in the 1930s and the discovery of well‐distinguishable sleep stages in the 1950s. While electrophysiological recordings have been used to describe the sleeping brain in much detail, since the 1990s neuroimaging techniques have been applied to uncover

Unravelling Hidden Trophic Interactions Among Sea Urchin Juveniles and Macroinvertebrates by DNA Amplification

Molecular Ecology, Volume 34, Issue 24, December 2025.
ABSTRACT Rocky reefs may shift between two distinct stable states: productive algal forests, characterised by high abundance and biodiversity of macrofauna, and impoverished barrens, dominated by overgrazing sea urchins. Barren states may persist despite the recovery of adult sea urchin predators, suggesting additional stabilising mechanisms.

Traffic-Estimation-Based Low-Latency XGS-PON Mobile Front-Haul for Small-Cell C-RAN Based on an Adaptive Learning Neural Network

Applied Sciences, 2018
In this paper, we propose a novel method for low-latency 10-Gigabit-capable symmetric passive optical network (XGS-PON) mobile front-haul for small cell cloud radio access network (C-RAN) based on traffic estimation. In this method, the number of packets
