Characterization of 10-ft. Diameter Aluminum Alloy 2219 Integrally Stiffened Cylinders [PDF]

open access: yes
The integrally stiffened cylinder (ISC) process, pioneered by NASA Langley Research Center, offers significant savings for launch vehicle structures. The ISC process is a near net shape, advanced manufacturing method for fabrication of single-piece, thin-

Muon (g-2) Technical Design Report [PDF]

open access: yes, 2015
The Muon (g-2) Experiment, E989 at Fermilab, will measure the muon anomalous magnetic moment a factor-of-four more precisely than was done in E821 at the Brookhaven National Laboratory AGS.

Advancing Severe Plastic Deformation for Tubular Samples: Systematic Review and Machine Learning Optimization

open access: yesMetalMat, EarlyView.
This review highlights recent advancements in Severe Plastic Deformation (SPD) techniques tailored for tubular samples. The mechanisms of processing are critically discussed with emphasis on microstructural control and the governing process parameters that enable refinement to ultrafine‐ and nano‐grained structures. Comparative insights into equivalent

Proteomic Profiling of Alveolar Macrophages Identifies Loss of Lysosomal Content as an Indicator of Nanofiber‐Induced Frustrated Phagocytosis

open access: yesSmall, EarlyView.
This proteomic study examines how nanofibers affect lung macrophages by analyzing protein changes following exposure to various fibrous materials. Nanofibers triggered the release of inflammatory enzymes, and importantly, lysosomal content release was identified as an early event associated with frustrated phagocytosis. Seventeen sensitive and relevant

Study of orifice fabrication technologies for the liquid droplet radiator [PDF]

open access: yes
Eleven orifice fabrication technologies potentially applicable for a liquid droplet radiator are discussed. The evaluation is focused on technologies capable of yielding 25-150 microns diameter orifices with trajectory accuracies below 5 milliradians ...

Thermo‐Chemically Modified Silk Scaffolds Reveal Niche‐Driven Regulation of Hematopoiesis and Fibrosis

open access: yesSmall, EarlyView.
We introduce a versatile 3D platform that recreates key physical and biological features of the human bone marrow. By integrating tunable silk biomaterials, stromal cells, and human hematopoietic progenitors, the model captures both healthy and diseased microenvironments, analysis of blood formation, and its disruption in pathological conditions ...

Mechanical Design of Carbon Ion Optics [PDF]

open access: yes
Carbon Ion Optics are expected to provide much longer thruster life due to their resistance to sputter erosion. There are a number of different forms of carbon that have been used for fabricating ion thruster optics.

The Effects of Human Presence, Restraint, and Stressed Neighbors on Corticosterone Levels in Domesticated Budgerigars (Melopsittacus undulatus)

open access: yesZoo Biology, EarlyView.
Female budgerigars (Melopsittacus undulatus) did not significantly elevate their plasma corticosterone levels in response to human presence at the beginning of the experiment. However, plasma corticosterone was significantly elevated by restraint stress, the return of a neighbor that received restraint stress, and human presence at the end of the ...
