Is Seasonal Adjustment a Linear or Nonlinear Data Filtering Process? [PDF]
In this paper, we investigate whether seasonal adjustment procedures are, at least approximately, linear data transformations. This question is important with respect to many issues including estimation of regression models with seasonally adjusted data.

Advanced Functional Materials, EarlyView.Ferroelectricity in thin HfO2‐based films offers great possibilities for next‐generation neuromorphic memory devices. There, the response to subcoercive voltage signals is driven by the movement of mobile interfaces and their interaction with crystal defects – a yet rather unexplored aspect, which we shed light on and gain new insights into the complex

Advanced Functional Materials, EarlyView.A chiral photodetector capable of selectively distinguishing left‐ and right‐handed circularly polarized light is experimentally demonstrated. The device, which features a nanopatterned electrode inverse‐designed by a genetic algorithm within a metal–dielectric–metal nanocavity that incorporates a vacuum‐deposited small‐molecule multilayer, exhibits ...

What can we tell about monetary policy synchronization and interdependence over the 2007-2009 global financial crisis? [PDF]
We investigate the synchronization and nonlinear adjustment dynamics of short-term interest rates for France, the UK and the US using the bi-directional feedback measures proposed by Geweke (1982) and appropriate smooth transition error-correction models

Spatially Tailorable Liquid Crystalline Elastomer Alignment During Digital Light Process 3D Printing
Advanced Functional Materials, EarlyView.Here, we report the fabrication of 3D printable liquid crystalline elastomer (LCE) structures with spatially tailorable alignment domains within the same layer. This work addresses the long‐standing challenge of preparing complex 3D LCE architectures with patterned functional domains to achieve nonlinear deformations. Fabrication of multi‐domains in 3D

A Dynamic Flexible Partial-Adjustment Model of International Diffusion of the Internet [PDF]
The paper introduces a dynamic, flexible partial-adjustment model and uses it to analyze the diffusion of Internet connectivity. It specifies and estimates desired levels of Internet diffusion and the speed at which countries achieve the target levels ...

Nonlinear Adjustable Robust Optimization
Robust Optimization (RO) is a popular approach for dealing with uncertain data in optimization. In static robust optimization, decision variables represent here-and-now decisions made without exact knowledge of uncertain parameters but must be feasible when the actual data is within the uncertainty set.

Lithium Intercalation in the Anisotropic Van Der Waals Semiconductor CrSBr
Advanced Functional Materials, EarlyView.We report the lithium intercalation in the layered van der Waals crystal CrSBr, revealing strongly anisotropic ion‐migration dynamics. Optical and electrical characterization of exfoliated CrSBr shows lithium diffusion coefficients that differ by more than an order of magnitude along a‐ and b‐directions, consistent with molecular dynamics simulations ...

DYNAMIC INPUT DEMAND FUNCTIONS AND RESOURCE ADJUSTMENT FOR U.S. AGRICULTURE: STATE EVIDENCE [PDF]
The paper presents an econometric model of dynamic agricultural input demand functions that includes research based technical change and autoregressive disturbances and fits the model to data for a set of state aggregates pooled over 1950-82.
