GBT‐SAM: A Parameter‐Efficient Depth‐Aware Model for Generalizable Brain Tumor Segmentation on mp‐MRI

International Journal of Imaging Systems and Technology, Volume 36, Issue 4, July 2026.
ABSTRACT Gliomas are aggressive brain tumors that require accurate imaging‐based diagnosis, where automated segmentation plays a central role in assessing tumor morphology and guiding treatment decisions. Manual delineation of gliomas is time‐consuming and prone to variability, motivating the use of deep learning to improve consistency and alleviate ...

On the Extended Relationships Among EVM, BER and SNR as Performance Metrics

, 2006
In this paper, we relate the error vector magnitude (EVM) bit error rate (BER) and signal to noise ratio (SNR). We also present the fact that with such relationship it would be possible to predict or in cases substitute EVM in places of BER or even SNR ...

Lipid and Foam Cell Accumulation as Novel Pathological Features of Benign Prostatic Hyperplasia

The Prostate, Volume 86, Issue 10, Page 1157-1169, July 2026.
ABSTRACT Background Benign prostatic hyperplasia (BPH) encompasses a heterogeneous set of pathological processes that instigate lower urinary tract symptoms (LUTS). Using a mouse model of steroid hormone imbalance–induced lower urinary tract dysfunction, we identified luminal lipid‐laden foamy macrophages, although their presence and contribution to ...
