Understanding the impact of pediatric kidney transplantation on cognition: A review of the literature. [PDF]

open access: yesPediatr Transplant, 2023
Abstract Background Chronic kidney disease (CKD) is a relatively rare childhood disease that is associated with a wide array of medical comorbidities. Roughly half of all pediatric patients acquire CKD due to congenital anomalies of the kidneys and urinary tract, and of those with congenital disease, 50% will progress to end‐stage kidney disease (ESKD)

Micro-Satellite Systems Design, Integration, and Flight [PDF]

open access: yesMicromachines
Within the past decade, the aerospace engineering industry has evolved beyond the constraints of using single, large, custom satellites. Due to the increased reliability and robustness of commercial, off-the-shelf printed circuit board components ...

Mars Atmospheric Characterization with a ChipSat Swarm [PDF]

open access: yesJournal of Spacecraft and Rockets, 2021
A mission scenario is proposed, where a large number of centimeter-scale femto-spacecraft are dispersed from a CubeSat piggyback payload on a future Mars mission. This swarm would deliver real-time massively parallel sensing throughout entry, descent, and landing with in-orbit measurements, atmospheric characterization during descent, and even surface ...

Feasibility Analysis and Preliminary Design of ChipSat Entry for In-situ Investigation of the Atmosphere of Venus

open access: yes, 2020
Recent miniaturization of electronics in very small, low-cost and low-power configurations suitable for use in spacecraft have inspired innovative small-scale satellite concepts, such as ChipSats, centimeter-scale satellites with a mass of a few grams.

An Analytical Framework for Determining the Minimum Size of Highly Miniaturized Satellites: PlanarSats

open access: yesAerospace
This paper introduces a power-driven systems engineering methodology for the early-phase design of highly miniaturized satellites: PlanarSats. We derive an analytical framework linking power requirements, contingency policies, solar-cell performance, and

Decentralized Control of Electromagnetic ChipSat Swarm Formations

open access: yes, 2021
Small satellite formation missions offer new options for space exploration and scientific experiments. Groups of satellites flying within short relative distances allow various important applications, such as spatially distributed instruments for atmospheric sampling or remote sensing systems. The ability to independently control the relative motion of
