AWG-based optoelectronic router with QoS support

open access: yesSecond IFIP International Conference on Wireless and Optical Communications Networks, 2005. WOCN 2005., 2005
We present a router architecture with electronic queuing and a passive optical multi-channel network, which is based upon a single-hop star topology with an arrayed waveguide grating (AWG) at its center. The AWG's property of spatial wavelength reuse and both fixed-tuned and tunable transceivers enable simultaneous control and data transmission.

Impact of Body Weight Loss During Preoperative Chemoradiotherapy on Prognosis of Patients With Lower Rectal Cancer

open access: yesAnnals of Gastroenterological Surgery, Volume 10, Issue 3, Page 722-738, May 2026.
The present study aimed to investigate the relationship between changes in body weight and composition during chemoradiotherapy, such as the psoas muscle mass index, visceral fat index, and subcutaneous fat index obtained from computed tomography images, and long‐term outcomes in rectal cancer patients.

Wavelength switched hybrid TDMA/WDM (TWDM) PON: a flexible next-generation optical access solution [PDF]

open access: yes, 2012
In this paper, we propose the system concepts of a next-generation wavelength switched hybrid time division multiple access and wavelength division multiplexing (TWDM) passive optical network (PON) architecture. In this architecture, wavelength selective

Association of Sarcopenia With Cognitive Function in Patients With Parkinson's Disease: A Cross‐Sectional Study

open access: yesBrain and Behavior, Volume 16, Issue 5, May 2026.
Among 148 older patients with Parkinson's disease, lower MoCA scores were independently associated with higher odds of sarcopenia, while higher HAMA scores were also associated with sarcopenia. Cognitive assessment may help screen for sarcopenia risk in this population. ABSTRACT Purpose This study aimed to investigate the association between sarcopenia

Modeling and study of FBG interrogator based on a two-dimensional image sensor

open access: yesНаучно-технический вестник информационных технологий, механики и оптики
Fiber Bragg Grating (FBG) interrogators contain a movable scattering element that tracks the FBG central wavelength. The movable element of the interrogator limits the interrogation speed.

Highly Versatile Real‐Time Optical Noise Filtering Through Temporal Cloaking

open access: yesLaser &Photonics Reviews, Volume 20, Issue 10, 22 May 2026.
Conventional bandpass filtering strategies may be insufficient for recovering optical waveforms under extremely noisy conditions. We demonstrate a temporal‐cloaking denoising strategy enabled by the temporal Talbot effect, which concentrates the coherent signal of interest into short temporal slots while broadband noise remains temporally spread.
