A green open access optical distribution network with incremental deployment support [PDF]

, 2015
This paper proposes an optical distribution network (ODN) architecture for open access networks. The proposed scheme ensures co-existence of multiple business partners (BPs) e.g., service, network equipment, and infrastructure providers at different ...

Time Out: A Scoping Review of Non‐Duration Based Social Media Use Measures and Adolescent Mental Health

Journal of Adolescence, Volume 98, Issue 3, Page 659-677, April 2026.
ABSTRACT Introduction Research to understand the role of social media use (SMU) in explaining deteriorating adolescent mental health has been limited by broad, nonspecific measures of social media use, specifically ‘time spent on social media’. These measures provide insufficient detail to capture specific risk and protective factors to users.

Upgrading and extending PON by using in-band WDM overlay

Journal of Microwaves, Optoelectronics and Electromagnetic Applications
This paper presents a new approach to upgrade and extend the reach of the current passive optical network (PON) by using wavelength division multiplexing (WDM) in the standardized optical grid of gigabit PON (In-band WDM PON overlay).

Comparative Neuromechanical Wing‐Actuation Architectures of Flapping Flight in Insects, Hummingbirds, and Robots

Advanced Intelligent Systems, Volume 8, Issue 3, March 2026.
Natural fliers achieve remarkable aerial performance through diverse wing neuromechanical systems integrating actuation, sensing, and control. This study synthesizes neuromechanical architectures in insects and hummingbirds, identifying two key functional types‐Dual Neural‐Mechanical Oscillator and Neurally‐modulated Mechanical Oscillator‐ and ...

Experience‐Sensitive Effects on Temporal Profiles of Social Attention in Early Childhood

Infancy, Volume 31, Issue 2, March/April 2026.
ABSTRACT Bilinguals show differences in face processing compared to monolinguals, automatically orienting more rapidly to faces and dwelling longer on faces and mouths than monolinguals. However, it is difficult to identify specific visual strategies from average‐level data.

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.

Acoustic Sensing as a Tool for Brain Tumor Diagnostics

Advanced Sensor Research, Volume 5, Issue 2, February 2026.
Surface acoustic wave (SAW) sensing is used to distinguish non‐neoplastic brain tissue from primary and metastatic tumors based on their acoustic attenuation signatures. Ex vivo human brain samples reveal clear tissue‐specific mechanical profiles, correlating with stiffness and malignancy.
