In order to satisfy timeliness requirements arising from environmental sensing applications, Age of Information (AoI) was proposed characterize the freshness received updates. this article, we consider a wireless powered relay aided communication network (WPRCN), in which wirelessly by hybrid-access point (H-AP) receives monitoring information update sensor and forwards it H-AP. The long-term a...

Mobile edge computing (MEC) has been recognized as a promising technique to provide enhanced computation services for low-power wireless devices at the network edge. How evaluate timeliness of task and data delivery is critical development MEC applications. Considering powered system, in this letter we study average age information (AoI), which crucial performance metric measure freshness infor...

There are large differences in the average age at death of scientists in different specialties whose death-notices appeared in Science from 1958 to 1968. They range from 76.7 for archaeologists to 61.8 for men working with radiation. The average age at death for the entire sample of 2,224 men was 67.7; and 68.1 for the total sample of 93 women. The average age at death was appreciably higher fo...

Spatial normalization, registration, and segmentation techniques for Magnetic Resonance Imaging (MRI) often use a target or template volume to facilitate processing, take advantage of prior information, and define a common coordinate system for analysis. In the neuroimaging literature, the MNI305 Talairach-like coordinate system is often used as a standard template. However, when studying pedia...

Otosclerosis is an inflammatory disease of the human temporal bone which was assumed to affect up to 10% of the Caucasians. Histologic otosclerosis has an incidence of 3.4%. It is considered as a major cause of hearing loss in Western countries while a low incidence is observed among Africans. Many hypotheses about its origin had been formulated in the past. Otosclerosis genes (OTSC1-5) and col...

The recent proposal by Bongaarts and Feeney for a tempo-adjustment to life expectancy is assessed using numerical techniques. I find that for a wide variety of situations no such adjustment is necessary provided mortality is observed in a given period. Bongaarts and Feeney assume the force of mortality affecting the mean age of death is not always observed. The present work brings into sharper ...

This article summarizes a life-span neurodevelopmental MRI database. The study of neurostructural development or neurofunctional development has been hampered by the lack of age-appropriate MRI reference volumes. This causes misspecification of segmented data, irregular registrations, and the absence of appropriate stereotaxic volumes. We have created the "Neurodevelopmental MRI Database" that ...
