A Unified Approach to Estimating Production Functions: Proxy Variables and Dynamic Panel Data

The Journal of Industrial Economics, EarlyView.
ABSTRACT We propose a new approach to production function estimation that integrates the strengths of the proxy‐variable (PV) and dynamic panel data (DPD) methods. Our framework augments the set of instruments for the level equation in Blundell and Bond [8] with a Berkson‐type instrument motivated by economic theory, following Olley and Pakes [28 ...

Solitons for the nonlinear Klein-Gordon equation

, 2010
In this paper we study existence and orbital stability for solitary waves of the nonlinear Klein-Gordon equation. The energy of these solutions travels as a localized packet, hence they are a particular type of solitons.

Carbohydrate content governs growth‐storage allocation during recovery from carbon depletion

New Phytologist, EarlyView.
Conceptual framework for competing hypotheses of growth‐storage carbon allocation during recovery from carbon limitation. Summary How plants prioritize carbon (C) allocation between growth and storage remains an outstanding question, limiting predictions of forest C cycling and ecosystem resilience following periods of C limitation. To address this gap,

Leaf nutrient resorption across contrasting soil parent materials: it is not just about efficiency

New Phytologist, EarlyView.
Box plots showing nitrogen (N) and phosphorus (P) concentrations in senesced leaves across contrasting parent materials for four site groups. Summary In theory, nutrient resorption from leaves should be higher in sites with lower soil nutrients, increasing the retention and reuse of nutrients that are limited in supply.

Disturbance legacies in arid environments shape recovery of former agricultural land

Restoration Ecology, EarlyView.
Abstract Introduction Increasingly, arid agricultural land is being permanently taken out of irrigated production due to more frequent drought, higher temperatures, and the overconsumption of groundwater, with important ramifications for ecological recovery.

Global meta‐analysis highlights recovery of animal functional diversity in restored coastal ecosystems

Restoration Ecology, EarlyView.
Abstract Introduction Coastal ecosystems have experienced widespread global degradation, prompting substantial investment in restoration. While structural recovery is well documented, whether restoration reestablishes the functional diversity (FD) of animal communities and how recovery unfolds through time remains poorly resolved. Objectives This study

Fecal degradation and nutrient loss of manure from cattle offered four bermudagrass cultivars

Agrosystems, Geosciences &Environment, Volume 9, Issue 4, December 2026.
Abstract Bermudagrass (Cynodon spp.) is one of the most common warm‐season perennial grasses utilized in the southeastern United States for pasture or stored forage. However, there is a paucity of data evaluating the fecal nutrient losses overtime by cattle grazing different bermudagrass cultivars.

Multimodal Analytical Platform Coupled With Biological Assays Unravels Tissue‐Specific Chemical Profiles, Spatial Metabolite Distributions and Bioactivities of Root Xylem and Root Bark of Tripterygium wilfordii

Analytical Science Advances, Volume 7, Issue 2, December 2026.
ABSTRACT Characterising chemical and biological differences among different tissues of medicinal plants is important for understanding their tissue‐specific characteristics and medicinal efficacy. The root xylem (RX) and root bark (RB) of Tripterygium wilfordii have historically been used differently; however, the basis underlying their differential ...

Dielectric Relaxation, Water Sorption Thermodynamics, and Humidity‐Sensing Mechanisms of Compressed Ulva Biomass Pellets

Applied Research, Volume 5, Issue 6, December 2026.
This study investigates the moisture sorption thermodynamics, dielectric relaxation behavior, and humidity‐sensing performance of compressed Ulva biomass pellets. The findings demonstrate that sustainable macroalgal pellets provide low hysteresis (~1.63%) and wide‐range sensitivity for green environmental diagnostics.
