Study of the Effects of Mold Coating on the Birefringence of Injection‐Molded Optical‐Quality Polycarbonate

open access: yesPolymer Engineering &Science, EarlyView.
Experimental and numerical evaluation of birefringence of injection molded parts ABSTRACT This study investigates the impact of mold surface coatings on the birefringence of injection‐molded optical‐quality polycarbonate lenses. Birefringence, caused by residual stresses during molding, affects optical clarity and performance.

Decoupling Formulation and Processing Effects in Thermoplastic Starch Through a Data‐Driven Structure–Property Framework

open access: yesPolymer Engineering &Science, EarlyView.
Processing‐property relationships in thermoplastic starch (TPS): plasticizer type, starch source and melt‐processing temperature establish a hierarchy of effects that governs process‐induced changes and the resulting TPS properties. ABSTRACT Thermoplastic starch (TPS) is a melt‐processable biopolymer whose properties depend strongly on formulation and ...

Generalizing the Gaussian Network Model: Spanning‐Tree Thermodynamics Shows Entropy‐Driven KRAS Activation

open access: yesProteins: Structure, Function, and Bioinformatics, EarlyView.
ABSTRACT The GTPase KRAS executes a conformational switch between a GTP‐bound active state and a GDP‐bound inactive state, a process central to oncogenic signaling. However, the structural basis of this switching at the level of residue‐contact organization remains incompletely characterized by traditional binary structural models.

New views of some invariants associated with the Cartesian 2D velocity gradient tensor

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
Vorticity and divergence of horizontal flow are fundamental quantities in meteorology; both are linear functions of the four elements of the 2D velocity gradient tensor and both are formally unchanged under coordinate rotation. We explore four quadratic functions of the elements that are geometrically invariant in this sense, finding some novel ...

Propagation of internal gravity waves: Optimal vertical discretisation and grid design based on numerical error analysis

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
An energy‐conserving discrete framework for the vertical discretisation of stratified ocean models is developed using internal gravity‐wave theory. A β$$ \beta $$‐indexed family of schemes is analysed through perturbation theory, revealing optimal parameter choices and grid designs that reduce truncation errors significantly.

Input–Output Finite‐Time Stability and Stabilization of Nonautonomous Nonlinear Quadratic Systems via State and Output Feedback

open access: yesInternational Journal of Robust and Nonlinear Control, EarlyView.
ABSTRACT This paper presents novel results regarding the input–output finite‐time stability (IO‐FTS) of nonlinear quadratic systems (NLQSs), a class of dynamical models particularly useful for the study of robotic systems, biochemical reaction networks, and other processes of interest to the applied sciences.
