Age-Aware Utility Maximization in Relay-Assisted Wireless Powered Communication Networks
Entropy, 2021 This article investigates a relay-assisted wireless powered communication network (WPCN), where the access point (AP) inspires the auxiliary nodes to participate together in charging the sensor, and then the sensor uses its harvested energy to send ...

Fireworks for the information age [PDF]
Proceedings of the National Academy of Sciences, 2009 What is the information content of a molecule? What is the data transmission rate associated with a chemical reaction? In contemplating such questions, Thomas et al. in this issue of PNAS (1) arrive at an interesting prototype device that stores and retrieves information by using only chemistry and chemical processes.

Optimization Algorithms for UAV-and-MUV Cooperative Data Collection in Wireless Sensor Networks
Drones, 2023 The deployment of unmanned aerial vehicles (UAVs) has significantly improved the efficiency of data collection for wireless sensor networks (WSNs). The freshness of collected information from sensors can be measured by the age of information (AoI), which

Lexicography in the Information Age
Lexikos, 2010 Lexicography has much to contribute to the information and knowledge society. The very essence of lexicography is its capacity to provide quick and easy access to data from which information needed by different types of users in different types of social situations can be re-trieved.

Age of Information With Non-Poisson Updates in Cache-Updating Networks [PDF]
arXiv, 2023 We study age of information in multi-hop multi-cast cache-enabled networks where the inter-update times on the links are not necessarily exponentially distributed. We focus on the set of non-arithmetic distributions for inter-update times, which includes continuous probability distributions as a subset.

Ordinal Classification with Distance Regularization for Robust Brain Age Prediction [PDF]
, 2023 Age is one of the major known risk factors for Alzheimer's Disease (AD). Detecting AD early is crucial for effective treatment and preventing irreversible brain damage. Brain age, a measure derived from brain imaging reflecting structural changes due to aging, may have the potential to identify AD onset, assess disease risk, and plan targeted ...

Linnaeus in the information age
Nature, 2007 As we celebrate the visionary genius of Carl Linnaeus, it is time to analyse how professional taxonomy interfaces with the rest of biology and beyond. Where next for Linnaeus's heirs, asks H. C. J. Godfray? The 300th anniversary of the birth of Linnaeus is being celebrated in 2007. This week's Nature joins the fun.

ReportAGE: Automatically extracting the exact age of Twitter users based on self-reports in tweets [PDF]
, 2021 Advancing the utility of social media data for research applications requires methods for automatically detecting demographic information about social media study populations, including users' age. The objective of this study was to develop and evaluate a method that automatically identifies the exact age of users based on self-reports in their tweets.

Age-Aware Stochastic Hybrid Systems: Stability, Solutions, and Applications [PDF]
arXiv, 2021 In this paper, we analyze status update systems modeled through the Stochastic Hybrid Systems (SHSs) tool. Contrary to previous works, we allow the system's transition dynamics to be polynomial functions of the Age of Information (AoI). This dependence allows us to encapsulate many applications and opens the door for more sophisticated systems to be ...

Pluralistic Aging Diffusion Autoencoder [PDF]
arXiv, 2023 Face aging is an ill-posed problem because multiple plausible aging patterns may correspond to a given input. Most existing methods often produce one deterministic estimation. This paper proposes a novel CLIP-driven Pluralistic Aging Diffusion Autoencoder (PADA) to enhance the diversity of aging patterns.
