Deep learning (DL)‐based advancements in prostate cancer imaging: Artificial intelligence (AI)‐based segmentation of 68Ga‐PSMSA PET for tumor volume assessment

Precision Radiation Oncology, EarlyView.
This review highlights the use of 68Ga‐PSMA PET in prostate cancer (PC) for tumor volume quantification, crucial for staging, treatment planning, and prognosis. Traditional manual segmentation methods are time‐consuming and variable, while AI‐based segmentation techniques, particularly deep learning models like convolutional neural networks, offer ...

Simple Heterogeneous Step‐Stress Accelerated Life Testing Model Under Type II Censoring

Quality and Reliability Engineering International, EarlyView.
ABSTRACT Common step‐stress accelerated life testing (SSALT) models assume that all testing items are sampled from a homogeneous population. However, this is often not the case in practice. Practitioners observe inhomogeneous aging patterns among items of the same production batch. This work proposes a simple SSALT model with exponentially distributed,

Physically Unclonable Function Utilizing Stochastic Indirect Exchange Interaction

Small Structures, EarlyView.
A physically unclonable function (PUF) utilizes manufacturing variations to create secret keys. This study proposes a spin–orbit torque PUF model based on the Ruderman–Kittel–Kasuya–Yosida interaction. It features near‐ideal properties that can operate under zero magnetic field and varying temperatures.
