Self-supervised Spatio-temporal Representation Learning for Videos by Predicting Motion and Appearance Statistics

open access: yes, 2019
We address the problem of video representation learning without human-annotated labels. While previous efforts address the problem by designing novel self-supervised tasks using video data, the learned features are merely on a frame-by-frame basis, which

Optical label switching

open access: yesOptical Fiber Communication Conference and International Conference on Quantum Information, 2001
Summary form only given. The design and implementation of a optical label switched router for packet switched WDM networks will be presented. The algorithms of generating optical labels, look-up tables, routing protocols, and a scaleable network architecture similar to IP/MPLS in optical domain will also be discussed.

A Comparative Study of Cerebral Oxygenation During Exercise in Hemodialysis and Peritoneal Dialysis Patients

open access: yesTherapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Introduction Cognitive impairment and exercise intolerance are common in dialysis patients. Cerebral perfusion and oxygenation play a major role in both cognitive function and exercise execution; HD session per se aggravates cerebral ischemia in this population. This study aimed to compare cerebral oxygenation and perfusion at rest and in mild

Predicting the Future Burden of Renal Replacement Therapy in Türkiye Using National Registry Data and Comparative Modeling Approaches

open access: yesTherapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Background Chronic kidney disease is a growing public health problem worldwide, and the number of patients requiring renal replacement therapy is steadily increasing. Türkiye has experienced a similar rise in both the incidence and prevalence of renal replacement therapy over the past decades; however, national‐level projections of future ...

Two‐mode multiplexed Fourier‐based labels

open access: yesElectronics Letters
A two‐mode optical packet switching architecture using an optical multiport mode‐division multiplexing label generator and processor is proposed. By combining optical labels on two modes, the number of labels is increased exponentially.

High-speed Video from Asynchronous Camera Array [PDF]

open access: yes, 2019
This paper presents a method for capturing high-speed video using an asynchronous camera array. Our method sequentially fires each sensor in a camera array with a small time offset and assembles captured frames into a high-speed video according to the ...
