An Alternative Estimation to Spurious Regression Model [PDF]
In sturdy econometrics specification search problems of unit roots and multicollinearity are well documented since the inception of regression analysis.

Advanced Science, EarlyView.Autonomous laboratories can now synthesize materials faster than experts can interpret the resulting diffraction data. A probabilistic framework combines refinement‐fit metrics with large language model‐derived chemical reasoning to rank competing phase interpretations and flag those unsuitable for autonomous use.

Free-form catenary-inspired meta-couplers for ultra-high or broadband vertical coupling
NanophotonicsMetasurface-assisted waveguide couplers, or meta-couplers, innovatively link free-space optics with on-chip devices, offering flexibility for polarization and wavelength (de)multiplexing, mode-selective coupling, and guided mode manipulation.

Inappropriate Detrending and Spurious Cointegration [PDF]
The empirical literature is abundant with detrended cointegration, where cointegration relationships are tested and estimated with deterministic trend terms. Cointegration is, however, critically dependent on whether time series is detrended or not.

Advanced Science, EarlyView.DDSurfer reconstructs cortical surfaces directly from diffusion MRI without requiring T1‐weighted scans. By fusing complementary microstructural features and learning diffeomorphic deformations, it efficiently generates accurate white matter and pial surfaces, improving geometric fidelity and morphometric reliability across datasets for robust surface ...

Stationarity of time series and the problem of spurious regression [PDF]
The goal of this paper was to introduce some general issues of non-stationarity for practitioners, students and beginning researchers. Using elementary techniques we examined the effect of non-stationary data on the results of regression analysis.

Hamaker Constants of van der Waals Materials under Clean‐Interface Conditions
Advanced Science, EarlyView.Clean‐interface adhesion in representative van der Waals materials is quantified by Ultra High Vacuum (UHV) Atomic Force Microscopy (AFM) with in situ cleaning and calibrated probes. Benchmark Hamaker constants for graphene, MoS2, and SiO2 are established, while humidity is shown to reversibly amplify adhesion, explaining much of the scatter in ...

Sensitivity of Principal Oscillation Patterns (POPs) to data distribution in space
Meteorologische Zeitschrift, 2008 The skill of the Principal Oscillation Pattern (POP) technique is tested with respect to a situation where harmonic waves of prescribed frequency and wavelength move over a domain where data are recorded at inhomogeneously distributed stations.
