Perspective Projection of an Ellipse and an Ellipsoid for Analytical View Factor Evaluation
ABSTRACT Radiative view factors are fundamental quantities for evaluating radiative heat transfer between different surfaces. While analytical expressions of view factors have been evaluated for various types of basic geometries, including circular disks and spheres, extending these solutions to more complex geometries, such as ellipses and ellipsoids ...

Beyond mechanics: Maximum‐likelihood‐driven PET detector alignment calibration
Abstract Background Accurate quantification is a cornerstone of positron‐emission tomography (PET), yet mechanical inaccuracies during detector assembly continue to undermine this goal. Deviations from intended design geometries arise due to factors such as manufacturing tolerances, mechanical stress, and cumulative errors during module installation ...

Abstract Purpose To analytically define a spiral waveform and trajectory that match the constraints of gradient frequency, slew rate, and amplitude. Theory and Methods Piecewise analytical solutions for gradient waveforms under the desired constraints are derived using the circle of an involute rather than an Archimedean spiral.

On the Stability Barrier of Hermite Type Discretizations of Advection Equations
ABSTRACT We establish a stability barrier for a class of high‐order Hermite‐type discretization of 1D advection equations underlying the hybrid‐variable (HV) and active flux (AF) methods. These methods approximate both cell averages and nodal solutions and evolve them in time simultaneously.

A Mechanism‐Based Multi‐Level Population PK/PD Model for Potassium‐Competitive Acid Blockers
Schematic overview of a mechanism‐based, multi‐level population model for potassium‐competitive acid blockers. ABSTRACT Potassium‐competitive acid blockers (PCABs) are emerging alternatives to proton pump inhibitors for the treatment of acid‐related diseases.
