NCOS News - January 2022

open access: yes, 2022
The Cheadle Center at UCSB manages the North Campus Open Space (NCOS), which is a project that has restored 136 acres of upland and wetland habitats that existed before the area was converted into the Ocean Meadows Golf Course in the 1960s. The NCOS restoration project began in 2017 with a fine-scale grading of the site in order to recreate the salt ...

Signal Amplification in the HPT Axis—Evidence for Its Existence, Location, Significance, and Molecular Mechanisms

open access: yesActa Physiologica, Volume 242, Issue 4, April 2026.
ABSTRACT Thyroid hormones (THs) are under negative feedback regulation via the hypothalamic–pituitary‐thyroid (HPT) axis. How this axis operates to keep the circulating THs within a narrow physiological range is not well understood quantitatively. Led by the design principle of robust homeostatic feedback control, here we review and synthesize the ...

Digital phase-lock loop having an estimator and predictor of error [PDF]

open access: yes, 1988
A digital phase-lock loop (DPLL) which generates a signal with a phase that approximates the phase of a received signal with a linear estimator. The effect of a complication associated with non-zero transport delays related to DPLL mechanization is then ...

Enhanced Dynamic Performance and Mechanical Reinforcement of Polyurea Coatings With Surface‐Modified Graphene Platelets

open access: yesJournal of Applied Polymer Science, Volume 143, Issue 11, March 15, 2026.
Morphology, mechanical properties and vibration damping properties of polyurea/GNP nanocomposites. ABSTRACT Studying structural dynamics of polyurea (PU) is pivotal to analyze its vibration‐damping features. In this study, a graphene‐reinforced PU coating with enhanced mechanical and damping properties was developed.
