Nonparametric Production Analysis under Alternative Price Conditions [PDF]

The literature on non-parametric production analysis has formulated tests for profit maximizing behavior that do not require a parametric specification of technology.

A Non-Parametric Test for a Two-Way Analysis of Variance

Mathematics
The methodology carried out in this work is based on non-parametric inference. The problem is framed as a regression analysis, and the solution is derived using the permutation approach.

Parametric tests of a 40-Ah bipolar nickel-hydrogen battery [PDF]

, 1986
A series of tests were performed to characterize battery performance relating to certain operating parameters which include charge current, discharge current, temperature, and pressure. The parameters were varied to confirm battery design concepts and to

Calpain small subunit homodimerization is robust and calcium‐independent

FEBS Letters, EarlyView.
Calpains dimerize via penta‐EF‐hand (PEF) domains. Using single‐molecule force spectroscopy, we measured the strength and kinetics of PEF–PEF homodimer binding. The interaction is robust, shows a transient conformational step before dissociation, and remains largely insensitive to Ca2+.

Structural insights into an engineered feruloyl esterase with improved MHET degrading properties

FEBS Letters, EarlyView.
A feruloyl esterase was engineered to mimic key features of MHETase, enhancing the degradation of PET oligomers. Structural and computational analysis reveal how a point mutation stabilizes the active site and reshapes the binding cleft, expading substrate scope.

Using Non-Parametric Tests to Evaluate Traffic Forecasting Performance. [PDF]

, 2002
This paper proposes the use of a number of nonparametric comparison methods for evaluating traffic flow forecasting techniques. The advantage to these methods is that they are free of any distributional assumptions and can be legitimately used on small ...

Valosin‐containing protein counteracts ATP‐driven dissolution of FUS condensates through its ATPase activity in vitro

FEBS Letters, EarlyView.
Biomolecular condensates formed by fused in sarcoma (FUS) are dissolved by high ATP concentrations yet persist in cells. Using a reconstituted system, we demonstrate that valosin‐containing protein (VCP), an AAA+ ATPase, counteracts ATP‐driven dissolution of FUS condensates through its D2 ATPase activity.

PARAMETRIC AND NONPARAMETRIC MARKET POWER TESTS: AN EMPIRICAL INVESTIGATION [PDF]

Parametric and nonparametric market power tests most commonly used to assess imperfectly competitive behavior are identified. Monte Carlo experiments are used to assess the accuracy of eight nonparametric tests.
