Community drivers of tuberculosis diagnostic delay in Kampala, Uganda: a retrospective cohort study

open access: yesBMC Infectious Diseases, 2021
Background Recent approaches to TB control have focused on identifying and treating active cases to halt further transmission. Patients with TB symptoms often delay to seek care, get appropriate diagnosis, and initiate effective treatment.

Research of real-time adaptive scheduling algorithm for across segments delay in EPA

open access: yesGong-kuang zidonghua, 2013
In view of problem that EPA network only supports real-time data transmission inside segments but not across segments, a real-time adaptive scheduling algorithm for across segments delay in EPA was proposed. Transmission process of across segments in EPA

Source-Channel Coding under Energy, Delay and Buffer Constraints [PDF]

open access: yes, 2014
Source-channel coding for an energy limited wireless sensor node is investigated. The sensor node observes independent Gaussian source samples with variances changing over time slots and transmits to a destination over a flat fading channel.

Optimizing MEC Networks for Healthcare Applications in 5G Communications With the Authenticity of Users’ Priorities

open access: yesIEEE Access, 2019
Mobile edge computing (MEC) is pervasive to support high-speed end-to-end data transmission and computation for 5th generation (5G) mobile communications by offloading computation tasks to the cloud at the edge of a cellular base station.

Antenna-coupled millimeter-wave LiNbO_3 electro-optic modulator [PDF]

open access: yes, 1991
The phase-velocity mismatch due to material dispersion in traveling-wave LiNbO_3 optical waveguide modulators may be greatly reduced by breaking the modulation transmission line into short segments and connecting each segment to its own surface antenna.

Synchronization in networks of mutually delay-coupled phase-locked loops

open access: yesNew Journal of Physics, 2014
Electronic components that perform tasks in a concerted way rely on a common time reference. For instance, parallel computing demands synchronous clocking of multiple cores or processors to reliably carry out joint computations.

Dynamics of parkinsonian oscillations mediated by transmission delays in a mean-field model of the basal ganglia

open access: yesFrontiers in Cellular Neuroscience
IntroductionNeural interactions in the brain are affected by transmission delays which may critically alter signal propagation across different brain regions in both normal and pathological conditions.

Transmission and group delay of microring coupled-resonator optical waveguides [PDF]

open access: yes, 2006
We measured the transmission and group delay of microring coupled-resonator optical waveguides (CROWs). The CROWs consisted of 12 weakly coupled, microring resonators fabricated in optical polymers (PMMA on Cytop).
