Introduction: The linear and continuous increase in power output (PO) during ramp incremental (RI) exercise causes a distinct V̇O2/PO relationship compared to constant work rate (CWR) exercise. Current methods enabling a translation of ramp-derived PO to CWR PO assume a linear development of the CWR V̇O2/PO relationship in the heavy-intensity domain. This study aimed to model the RI versus CWR V̇O2/PO relationship to investigate whether the loss of mechanical efficiency above GET develops linearly.

This study assessed the impact of a multi-disciplinary HPV educational intervention on oral health care professionals' perceived role, comfort level, and scope of practice in HPV-related cancer prevention efforts.
Methods: The virtual educational intervention was provided by a multi-disciplinary panel of experts.
Purpose: The aims of this study were (1) to assess the test-retest reliability of the primary near infrared spectroscopy (NIRS) variables (i.e., StO, T[Hb], [HbO] and [HHb]) during cycling and (2) to investigate potential influences of exercise intensity and adipose tissue thickness (ATT) on this reliability.

Purpose: A thermionic cathode x-ray system employing two-dimensional (2D, planar) multiple x-ray-source arrays (MXA) is proposed to improve DBT image quality.
Methods: A 1D MXA, consisting of a linear array of thermionic cathodes was used to simulate a 2D MXA.
