Minimize the Prediction Error in External Consensus Problem using Gain Error Ratio Formula

open access: yesApplications of Modelling and Simulation, 2017
This paper discusses the external consensus problem for non-identical networked multi-agent systems (NMAS) with network data loss, considering uniform consecutive data losses (CDL) induced by long periods of transmission failure. A gain error ratio (GER)

Erasure Insertion in RS-Coded SFH MFSK Subjected to Tone Jamming and Rayleigh Fading

open access: yes, 2005
The achievable performance of Reed Solomon (RS) coded slow frequency hopping (SFH) assisted M-ary frequency shift keying (MFSK) using various erasure insertion (EI) schemes is investigated, when communicating over uncorrelated Rayleigh fading channels in

Transcriptional network analysis of PTEN‐protein‐deficient prostate tumors reveals robust stromal reprogramming and signs of senescent paracrine communication

open access: yesMolecular Oncology, EarlyView.
Combining PTEN protein assessment and transcriptomic profiling of prostate tumors, we uncovered a network enriched in senescence and extracellular matrix (ECM) programs associated with PTEN loss and conserved in a mouse model. We show that PTEN‐deficient cells trigger paracrine remodeling of the surrounding stroma and this information could help ...

Performance analysis of amplify-and-forward cooperative communication systems with imperfect channel estimation

open access: yesTongxin xuebao, 2011
The impact of channel estimation errors on the performance for two-hop multi-relays assisted am-plify-and-forward(AF) cooperative communication systems was investigated.Closed-form expressions of the average symbol error rate,as well as the diversity ...

Measuring of Block Error Rates in High-Speed Digital Networks

open access: yesAdvances in Electrical and Electronic Engineering, 2006
Error characteristics is a decisive factor for the digital networks transmission quality definition. The ITU – TG.826 and G.828 recommendations identify error parameters for high – speed digital networks in relation to G.821 recommendation.

The PI3Kδ inhibitor roginolisib (IOA‐244) preserves T‐cell function and activity

open access: yesMolecular Oncology, EarlyView.
Identification of novel PI3K inhibitors with limited immune‐related adverse effects is highly sought after. We found that roginolisib and idelalisib inhibit chronic lymphocytic leukemia (CLL) cells and Treg suppressive functions to similar extents, but roginolisib affects cytotoxic T‐cell function and promotion of pro‐inflammatory T helper subsets to a

A method of back-calculating the log odds ratio and standard error of the log odds ratio from the reported group-level risk of disease.

open access: yesPLoS ONE, 2020
In clinical trials and observational studies, the effect of an intervention or exposure can be reported as an absolute or relative comparative measure such as risk difference, odds ratio or risk ratio, or at the group level with the estimated risk of ...

AC/A ratio, age, and refractive error in children

open access: yesAmerican Journal of Ophthalmology, 1999
To examine how the response AC/A ratio (the amount of accommodative convergence per unit of accommodative response) varies as a function of refractive error and age, to determine whether it is a risk factor for the onset of myopia, and to examine the relation between ocular structural features and the AC/A ratio.Accommodation was stimulated by a letter

Circular RNA expression landscapes in myelodysplastic neoplasms: Associations with mutational signatures and disease progression

open access: yesMolecular Oncology, EarlyView.
In this explorative study, the abundance of circular RNA molecules in bone marrow stem cells was found to be elevated in patients with high‐risk myelodysplastic neoplasms, and to be associated with an increased risk of progression to acute myeloid leukemia.

A comparison of the accuracy of saddlepoint conditional cumulative distribution function approximations

open access: yes, 2007
Consider a model parameterized by a scalar parameter of interest and a nuisance parameter vector. Inference about the parameter of interest may be based on the signed root of the likelihood ratio statistic R.
