Characterization of electroless nickel-phosphorus plating for ultracold-neutron storage

Kavli Affiliate: A. C. Davis | Summary:Electroless nickel plating is an established industrial process that provides a robust and relatively low-cost coating suitable for transporting and storing ultracold neutrons (UCN). Using roughness measurements and UCN-storage experiments we characterized UCN guides made from polished aluminum or stainless-steel tubes plated by several vendors. All electroless nickel platings […]

Evidence for PeV Proton Acceleration from Fermi-LAT Observations of SNR G106.3+2.7

Kavli Affiliate: Eric Charles | First 5 Authors: Ke Fang, Matthew Kerr, Roger Blandford, Henrike Fleischhack, Eric Charles | Summary: The existence of a "knee" at energy ~1 PeV in the cosmic-ray spectrum suggests the presence of Galactic PeV proton accelerators called "PeVatrons". Supernova Remnant (SNR) G106.3+2.7 is a prime candidate for one of these. […]

Orbitofrontal cortex populations are differentially recruited to support actions

Kavli Affiliate: Christina Gremel | Authors: Christian Cazares, Drew C. Schreiner, Mariela Lopez Valencia and Christina M. Gremel | Summary: Summary The ability to use information from one’s prior actions is necessary for decision-making. While Orbitofrontal cortex (OFC) has been hypothesized as key for inferences made using cue and value-related information, whether OFC populations contribute […]

Towards a comprehensive view of accretion, inner disks, and extinction in classical T Tauri stars: an ODYSSEUS study of the Orion OB1b association

Kavli Affiliate: Gregory J. Herczeg | First 5 Authors: Caeley V. Pittman, Catherine C. Espaillat, Connor E. Robinson, Thanawuth Thanathibodee, Nuria Calvet | Summary: The coevolution of T Tauri stars and their surrounding protoplanetary disks dictates the timescales of planet formation. In this paper, we present magnetospheric accretion and inner disk wall model fits to […]

Protein Geometry, Function and Mutation

Kavli Affiliate: Robert Clark | Authors: Robert Clark Penner | Summary: Abstract This survey summarizes several works by the author on protein geometry and protein function with applications to viral glycoproteins in general and the spike glycoprotein of the SARS-CoV-2 virus in particular. Though a certain level of mathematical sophistication is assumed, the background biology […]
