Stability of spreading processes over time-varying large-scale networks

M Ogura, VM Preciado - IEEE Transactions on Network …, 2016 - ieeexplore.ieee.org
In this paper, we analyze the dynamics of spreading processes taking place over time-varying
networks. A common approach to model time-varying networks is via Markovian random …

[HTML][HTML] Characteristics of aspiration pneumonia patients in acute care hospitals: a multicenter, retrospective survey in Northern Japan

…, E Ishida, T Kikuchi, T Kudo, K Watanabe, M Ogura… - PLoS …, 2021 - journals.plos.org
Background Pneumonia is a common cause of illness and death of the elderly in Japan. Its
prevalence is escalating globally with the aging of population. To describe the latest trends in …

Geometric programming for optimal positive linear systems

M Ogura, M Kishida, J Lam - IEEE Transactions on Automatic …, 2019 - ieeexplore.ieee.org
This article studies the parameter tuning problem of positive linear systems for optimizing their
stability properties. We specifically show that, under certain regularity assumptions on the …

Epidemic processes over adaptive state-dependent networks

M Ogura, VM Preciado - Physical Review E, 2016 - APS
In this paper we study the dynamics of epidemic processes taking place in adaptive networks
of arbitrary topology. We focus our study on the adaptive susceptible-infected-susceptible (…

Stability analysis of positive semi-Markovian jump linear systems with state resets

M Ogura, CF Martin - SIAM Journal on Control and Optimization, 2014 - SIAM
This paper studies the mean stability of positive semi-Markovian jump linear systems. We
show that their mean stability is characterized by the spectral radius of a matrix that is easy to …

Quantitative assessment of the pharyngeal airway by dynamic magnetic resonance imaging in obstructive sleep apnea syndrome

M Ogura, S Higano, W Hida, K Ikeda… - Annals of Otology …, 2001 - journals.sagepub.com
Dynamic changes in the pharyngea airway of patients with obstructive sleep apnea syndrome
(OSAS) were evaluated by quantitating the findings of real-time imaging performed during …

Three-dimensional computed tomography imaging in the sitting position for the diagnosis of patulous eustachian tube

T Kikuchi, T Oshima, M Ogura, Y Hori… - Otology & …, 2007 - journals.lww.com
Three-Dimensional Computed Tomography Imaging in the Sitting... : Otology & Neurotology
Three-Dimensional Computed Tomography Imaging in the Sitting Position for the Diagnosis …

State-feedback control of Markov jump linear systems with hidden-Markov mode observation

M Ogura, A Cetinkaya, T Hayakawa, VM Preciado - Automatica, 2018 - Elsevier
In this paper, we study state-feedback control of Markov jump linear systems with partial
information about the mode signal responsible for switching between dynamic modes. We …

Distributed collaborative 3D-deployment of UAV base stations for on-demand coverage

T Kimura, M Ogura - IEEE INFOCOM 2020-IEEE conference on …, 2020 - ieeexplore.ieee.org
Deployment of unmanned aerial vehicles (UAVs) performing as flying aerial base stations (BSs)
has a great potential of adaptively serving ground users during temporary events, such …

Distributed 3D deployment of aerial base stations for on-demand communication

T Kimura, M Ogura - IEEE Transactions on Wireless …, 2021 - ieeexplore.ieee.org
An aerial base station (ABS), ie, unmanned aerial vehicle-mounted base station, has a significant
potential to effectively boost the coverage of next-generation wireless networks, having …
