Model‐Based Systems Engineering in Space Applications: A Comprehensive Literature Review

Systems Engineering, EarlyView.
ABSTRACT The growing complexity of space engineering is driving the demand to embrace the adoption of Model‐Based Systems Engineering (MBSE). Although the MBSE is well‐practiced in the space industry, the level of effort and need required to obtain the benefits of MBSE vastly differ across enterprises; this disparity presents a significant challenge to

Integration of Micro‐CT and XRF Mapping for Multimodal 3D Analysis of Polychrome Wooden Artifacts

X-Ray Spectrometry, EarlyView.
ABSTRACT Over the past 5 years, computer applications have become crucial to archeological research. Since the 1990s, the focus has transitioned from data management tools to the development of virtual models. Recently, digital documentation of cultural heritage has gained considerable focus, with 3D modeling of objects.

X‐ray fluorescence microscopy exposure estimates using a single excitation energy

Journal of Synchrotron Radiation, EarlyView.
We present calculations on the number of illuminating photons per pixel required for elemental detection using X‐ray fluorescence, even with far‐from‐threshold excitation.Scanning fluorescence X‐ray microscopy is widely used for quantitative mapping of elemental concentrations, including in studies of essential but low‐concentration metals in cells ...

Magnetic Resonance Imaging Evaluation of Functional Differences Between In Vivo Human Kidneys and Discarded Human Kidneys During Ex Vivo Normothermic Machine Perfusion

Artificial Organs, EarlyView.
Comparative MRI of in vivo kidneys and ex vivo donor kidneys during NMP revealed marked physiological differences and limited correspondence with conventional perfusion or injury metrics. These distinct ex vivo MRI signatures emphasize the need to consider parameters beyond conventional in vivo functional markers when assessing organ viability during ...
