PA(aa)

open access: yesNotre Dame Journal of Formal Logic, 1995
The theory PA(aa), which is Peano Arithmetic in the context of stationary logic, is shown to be consistent. Moreover, the first-order theory of the class of finitely determinate models of PA(aa) is characterized.

Mechanochemical Synthesis and Characterization of Nanostructured ErB4 and NdB4 Rare‐Earth Tetraborides

open access: yesAdvanced Engineering Materials, Volume 27, Issue 6, March 2025.
ErB4 and NdB4 nanostructured powders are produced by mechanochemical synthesis. 5 h mechanical alloying and 4 M HCl acid leaching are used in the production. ErB4 and NdB4 powders exhibit maximum magnetization of 0.4726 emu g−1 accompanied with an antiferromagnetic‐to‐paramagnetic phase transition at about TN = 18 K and 0.132 emu g−1 with a maximum at ...

Beyond Primary Nucleation: Molecular Basis of Peptide Crystal Secondary Nucleation at Soft Interface

open access: yesAdvanced Functional Materials, EarlyView.
High spatiotemporal‐resolution atomic force microscopy directly resolved peptide secondary nucleation (SN) and growth characteristics and mechanisms on HOPG. The landscape of peptide nucleation sites, growth dynamics, molecular‐scale structures, phase transitions, and cross‐seeding processes were realized.

Functional validation of transposable element–derived cis-regulatory elements in Atlantic salmon

open access: yesG3: Genes, Genomes, Genetics, 2023
Transposable elements (TEs) are hypothesized to play important roles in shaping genome evolution following whole-genome duplications (WGDs), including rewiring of gene regulation.

Laser‐Induced Local De‐Doping in Organic Semiconductors

open access: yesAdvanced Materials Technologies, EarlyView.
The polymer PBTTT‐C14 doped with the small molecule acceptor F4TCNQ is considered as a benchmark material system. Mask‐free, microscale patterning of the doping level via laser‐induced heating and sublimation of dopant molecules is shown. Controlling laser irradiance and swath spacing allows dopant level control with laser‐limited resolution, opening ...
