SNR‐efficient whole‐brain pseudo‐continuous arterial spin labeling perfusion imaging at 7 T

Magnetic Resonance in Medicine, Volume 94, Issue 3, Page 965-981, September 2025.
Abstract Purpose To optimize pseudo‐continuous arterial spin labeling (PCASL) parameters to maximize SNR efficiency for RF power constrained whole brain perfusion imaging at 7 T. Methods We used Bloch simulations of pulsatile laminar flow to optimize the PCASL parameters for maximum SNR efficiency, balancing labeling efficiency and total RF power.

An innovative benefit‐of‐the‐doubt approach for health system effectiveness: a global case study on amenable mortality

International Transactions in Operational Research, Volume 32, Issue 5, Page 2847-2877, September 2025.
Abstract Health system performance assessment (HSPA) is essential for health planning and to improve population health. One of the HSPA domains is related to effectiveness, which can be represented considering different dimensions. Composite indicators can be used to summarize complex constructs involving several indicators. One example of such efforts

Leveraging SYCL for Heterogeneous cDTW Computation on CPU, GPU, and FPGA

Concurrency and Computation: Practice and Experience, Volume 37, Issue 15-17, 25 July 2025.
ABSTRACT One of the most time‐consuming kernels of a recent epileptic seizure detection application is the computation of the constrained Dynamic Time Warping (cDTW) Distance Matrix. In this paper, we explore the design space of heterogeneous CPU, GPU, and FPGA implementations of this kernel using SYCL as a programming model. First, we optimize the CPU

A passive convex optimal control algorithm for teleoperating a redundant robotic arm in minimally invasive surgery

International Journal of Robust and Nonlinear Control, Volume 35, Issue 10, Page 4132-4148, 10 July 2025.
Abstract In recent years, the remote center of motion (RCM) constraint has moved from purely mechanical to software implementation, enabling the use of serial manipulators in robotic‐assisted minimal invasive surgery. However, ensuring safety with software‐based RCM presents challenges.
