What are the universal constants of WLF equation?4 answersThe universal constants of the Williams-Landel-Ferry (WLF) equation, traditionally denoted as C1(g) and C2(g), are parameters that exhibit approximate universality across various glass-forming materials, implying that the segmental relaxation time τ(T) depends solely on the temperature difference T–Tg. However, recent studies have shown that these constants may not be truly universal, as they can vary significantly depending on the material properties, such as the degree of crosslinking in polymers like soy flour. The limitations of the WLF equation have been discussed, highlighting the challenges related to its universal applicability and the necessity for a broader temperature range for accurate determination of its constants. The WLF equation's molecular basis and its relation to other equations like the Vogel-Fulcher-Tammann equation have also been subjects of investigation.
What is the oracle property for estimation in machine learning?4 answersThe oracle property in machine learning refers to the property of an estimator performing as well as if the underlying model were known beforehand. It means that the estimator can accurately recover the true parameters of the model. Several papers in the provided abstracts discuss the oracle property in different contexts. For example, Liu and Shen propose a unified framework for sparse local embeddings for extreme classification (SLEEC) and prove that their estimator enjoys the oracle property and achieves a desirable statistical convergence rate. Xiong, Dai, and Qian show that the orthogonalising EM algorithm can find a local solution with the oracle property for non-convex penalties. Goldberg, Lu, and Fine suggest a methodology that reconciles treating the estimated transformation parameter as fixed or random, achieving rigorous frequentist inference while allowing for multiple candidate values for the transformation. Gui, Han, and Gu present a unified framework for low-rank matrix estimation with nonconvex penalty and prove that their estimator enjoys the oracle property and attains a faster rate. Giurcanu proposes a thresholding M-estimator for multivariate time series with the oracle property, where its large-sample properties are the same as the classical M-estimator obtained under the a priori information that the zero parameters were known.
Can the spring constant be negative?5 answersThe spring constant can be negative in certain cases. Structures have been found to exhibit negative moduli (negative stiffness) in apparent violation of thermodynamic principles, but they can only be stable as parts of encompassing positive stiffness structures. In the field of Microelectromechanical systems (MEMS), external springs with negative spring constant behavior have been used to modify the total spring constant of devices. Additionally, a mechanism with negative spring stiffness has been developed based on the instability of the second order buckling state of a flat plate spring clamped at both ends. These examples demonstrate that negative spring constants can be achieved in specific systems and can be utilized to modify the behavior of devices and mechanisms.
What is reaction rate constant?4 answersThe reaction rate constant is a parameter that characterizes the speed at which a chemical reaction takes place.

What is an alternative specific constant?5 answersAn alternative specific constant is a term used in models to capture period-specific unobservable factors. It is used in the context of time-period choice models, where constants are used to represent unobservable factors related to outbound, return, and duration periods. The high number of constants in these models can lead to issues of identification, computational cost, and interpretation. To address these problems, researchers have proposed using functional approximations instead of the full set of constants. Different approaches, both parametric and non-parametric, have been suggested, each with its own advantages and disadvantages. These approaches have shown that using a functional approximation can lead to significant gains in identification.
