Magic state cultivation on a superconducting quantum processor

Fault-tolerant quantum computing requires a universal gate set, but the necessary non-Clifford gates represent a significant resource cost for most quantum error correction architectures. Magic state cultivation offers an efficient alternative to resource-intensive distillation p...

High-Fidelity Electrochemistry with Ultraclean Graphene Electrodes

Abstract The electrochemical performance of CVD graphene electrodes has remained inconsistent and often inferior to that of exfoliated graphene, limiting their utility in analytical applications. This variability is widely attributed to structural disorder, but the dominant sourc...

The Mysteries of Real Materials

The presentation will consist in showing arc jet data mysterious to the modelers. It will show a short movie (10-20 sec) of an arc jet test where a material exhibited a failure mode that nobody understands followed by thermocouple data from arc jet tests on another material of in...

Assessing ozone dynamics during the 2023 summer STAQS field campaign using synergistic observations and model simulations

NASA's Tropospheric Emissions: Monitoring of Pollution (TEMPO) geostationary satellite sensor provides high temporal and spatial resolution measurements critical for monitoring air quality. During the Synergistic TEMPO Air Quality Science (STAQS) component of the 2023 AGES+ campa...

Computational and Experimental Comparison of CLF5605 and Roamx-0201 Martian Helicopter Rotor Airfoils

This study compares the performance of the CLF5605 rotor airfoil—which flew on Ingenuity—with that of a new optimized roamx-0201 airfoil designed for Martian conditions at NASA Ames Research Center. Specifically, performance is studied at a Reynolds number of 20,000 and a Mach nu...

Impact of simulated galactic cosmic radiation exposure on ovarian follicle development in mice

Exposure to galactic cosmic radiation (GCR) during deep space missions poses substantial risks to female reproductive (ovarian) and overall health, presenting a fundamental challenge for future exploration missions. To examine ovarian responses, 22-week-old C57BL/6J mice were exp...

The Curious Case of Centaurus A II: On the Subject of the Quenched satellites

The satellite system of Centaurus A presents a curious cosmological puzzle: while the global population is consistent with theoretical expectations, its inner regions (d<150 kpc) exhibit a deficit of luminous satellite galaxies. Using the Galacticus semi-analytic model applied to...

Assessing Water Dynamics at Lunar Gravity

Because future plant cultivation on the Moon will require lunar-gravity specific water management, we examined the behavior of water, a glycerol and saline solution under lunar gravity conditions during a flight experiment on Blue Origin’s New Shephard 29 mission. This mission si...

Evaluation of Pandora HCHO and NO 2 with airborne in situ observations

Abstract. The Pandora Global Network (PGN) is a system of ground-based spectrometers reporting continuous daytime column HCHO and NO2. While the Direct Sun (DS) NO2 product has been well studied, the Multi Axis Differential Optical Absorption Spectroscopy (MAX DOAS) products are...

Wavelength Requirements for Life Detection via Reflected Light Spectroscopy of Rocky Exoplanets

Searching for signs of life is a primary goal of the Habitable Worlds Observatory (HWO). However, merely detecting oxygen, methane, or other widely discussed biosignatures is insufficient evidence for a biosphere. In parallel with biosignature detection, exoplanet life detection...

Individual behavior and physiology of group housed mice in a spaceflight habitat

NASA has a robust history of biomedical investigations using rodent models in spaceflight. The results from these experiments have provided significant insights into the effects of spaceflight on mammalian physiological systems for fundamental, biomedical and commercial research...

Europe’s extreme temperatures and rainfall in finer detail: strengths and limits of climate model downscaling

<title>Abstract</title> Climate extremes in Europe are becoming increasingly frequent and severe, heightening the need for reliable regional climate information to support preparedness and adaptation. Downscaled climate model (DCM) products are widely used for this purpose. Yet,...

Polarization calibration of spaceborne lidar using dense cirrus–scattered solar background with molecular scattering correction

Abstract. Accurate calibration is essential for spaceborne polarization-sensitive lidars, as biases in depolarization ratio measurements can significantly affect the retrieval of cloud and aerosol properties. A polarization calibration technique based on solar background signals...
