Developing and Evaluating a Laboratory‐Based Frailty Index for the Prediction of Long‐Term Health Outcomes in Systemic Lupus Erythematosus

Arthritis Care &Research, EarlyView.
Objective We aimed to construct and evaluate the first laboratory‐based frailty index (FI‐Lab) for predicting adverse outcomes in systemic lupus erythematosus (SLE) and to compare its predictive ability to that of an existing clinical FI. Methods We used data from a single‐center prospective cohort of adult patients with SLE whose baseline visit ...

Handover management in beyond 5G HetNet topologies with unbalanced user distribution

Digital Communications and Networks
The increase in user mobility and density in modern cellular networks increases the risk of overloading certain base stations in popular locations such as shopping malls or stadiums, which can result in connection loss for some users. To combat this, the

Downlink Analysis in Unmanned Aerial Vehicle (UAV) Assisted Cellular Networks With Clustered Users

IEEE Access, 2018
The use of unmanned aerial vehicles (UAVs) operating as aerial base stations (BSs) has emerged as a promising solution especially in scenarios requiring rapid deployments (e.g., in the cases of crowded hotspots, sporting events, emergencies, and natural ...

High Health Care Utilization Preceding Diagnosis With Juvenile Idiopathic Arthritis

Arthritis Care &Research, EarlyView.
Objective Although early diagnosis improves long‐term outcomes, patients with juvenile idiopathic arthritis (JIA) often experience prolonged, circuitous paths to diagnosis. To inform diagnostic improvement, we sought to characterize health care utilization in the year preceding diagnosis. Methods We identified 10,021 patients with an incident diagnosis

Proactive Uplink Interference Management for Nonuniform Heterogeneous Cellular Networks

IEEE Access, 2020
In homogeneous cellular networks, fractional power control (FPC) is employed to partially compensate the path-loss and, hence, improve uplink (UL) signal-to-interference ratio (SIR).

Radioisotope Identification with List-Mode Gamma-Ray Data

Data Science in Science
This work explores the potential of utilizing temporal data from gamma-ray detectors, known as list-mode data, to enhance radioisotope identification. Traditional identification methods, which rely on full gamma-ray spectrum analysis, often require long ...

Transforming spatial point processes into Poisson processes

Stochastic Processes and their Applications, 1999
Let \(N\) be a simple point process in the quadrant \({\mathbb R}_+^2\). The author shows that if the `coordinate sectional' intensities (\(\lambda _1(\omega ,s,t),\lambda _2(\omega ,s,t)\)) exist and if with probability one, \(\int \lambda _1(\omega ,s,t)dt=\infty \) for all \(s>0\), then there exists a family of \({\mathcal F}^1\)-predictable sets \(\

Phase Field Failure Modeling: Brittle‐Ductile Dual‐Phase Microstructures under Compressive Loading

Advanced Engineering Materials, EarlyView.
The approach by Amor and the approach by Miehe and Zhang for asymmetric damage behavior in the phase field method for fracture are compared regarding their fitness for microcrack‐based failure modeling. The comparison is performed for the case of a dual‐phase microstructure with a brittle and a ductile constituent.

A notes bivariate power law processes: conditional intensity and parameter estimation techniques,

MethodsX
The point process model effectively represents the number of random events occurring over time through its intensity function. When events are of two types, a bivariate point process allows simultaneous analysis of each event’s intensity.
