The term structure of interest rates with nonlinear adjustment: Evidence from a unit root test in the nonlinear STAR framework [PDF]

open access: yes
This paper investigates the term structure of interest rates in Japan using the unit root test in a nonlinear STAR framework. The results provide strong evidence against the unit root of the yield spread between long-term and short-term interest rates ...

Dosimetric sensitivity of an enhanced leaf model (ELM) for individual versus averaged machines

open access: yesJournal of Applied Clinical Medical Physics, Volume 26, Issue 4, April 2025.
Abstract Background With the introduction of a new multi‐leaf collimator (MLC) enhanced leaf model (ELM) in the Varian Eclipse™ treatment planning system, there is currently limited data regarding the dosimetric sensitivity to real‐world variation in the ELM parameters, and its clinical relevance. Purpose To characterize the variation in ELM parameters

AAPM‐RSS Medical Physics Practice Guideline 9.b: SRS‐SBRT

open access: yesJournal of Applied Clinical Medical Physics, Volume 26, Issue 4, April 2025.
Abstract The purpose of this Medical Physics Practice Guideline (MPPG) is to describe the minimum level of medical physics support deemed prudent for the practice of linear‐accelerator, photon‐based (linac) stereotactic radiosurgery (SRS), and stereotactic body radiation therapy (SBRT) services.

The properties of asymmetric unit root tests in the presence of mis-specified asymmetry [PDF]

open access: yes
The seminal analysis of Enders and Granger (1998) is extended to examine the properties of asymmetric unit root tests when the nature of the actual asymmetric adjustment process underlying the observed data is unknown. The analysis is further extended by

AAPM Medical Physics Practice Guideline MPPG 17.a: Quality management for mammography review workstation displays

open access: yesJournal of Applied Clinical Medical Physics, Volume 26, Issue 4, April 2025.
Abstract The Mammography Quality Standards Act (MQSA) sets quality standards for displays used to interpret mammography images. With the shift to digital mammography and the widespread use of remote reading workstations (RWS), updated quality management (QM) programs are needed to ensure consistent image presentation and accurate interpretation.
