Nutrient dynamics of seasonal tanks in the dry zone of Sri Lanka in relation to their hydrological regimes [PDF]

open access: yes, 2002
Village tanks are put to a wide range of uses by the rural communities that depend on them for their survival. As the primacy of irrigation has decreased under these tanks due to a variety of climatic and economic reasons there is a need to reevaluate ...

In Situ Graph Reasoning and Knowledge Expansion Using Graph‐PRefLexOR

open access: yesAdvanced Intelligent Discovery, EarlyView.
Graph‐PRefLexOR is a novel framework that enhances language models with in situ graph reasoning, symbolic abstraction, and recursive refinement. By integrating graph‐based representations into generative tasks, the approach enables interpretable, multistep reasoning.

Market Structure and Price Responses to Seasonal Demand Changes [PDF]

open access: yes
The demand for gasoline follows a seasonal cycle in Sweden. The paper investigates the response in prices and profits over the cycle. In contrast to what has been found for the gasoline market in the United States I find no support for seasonal price ...

Workmen’s Compensation: Contagious Disease Held Compensable [PDF]

open access: yes, 1961
Knowledge about dispersion is of utmost importance for understanding populations’ reaction to changes in the environment. Expansion of a population range brings with it both spatial sorting and over time, spatial selection.

Multifunctional Position and Stiffness Control of Soft Fluidic Actuators Using Supercooled Liquid

open access: yesAdvanced Intelligent Systems, EarlyView.
This work explores the use of supercooled liquid as a multifunctional working fluid for soft actuators to allow independent control of position and stiffness; the solution is used to both inflate the elastomer chambers while in liquid state and to achieve a dramatic increase in stiffness (up to 13 times) with rapid, reversible crystallization.

Modelling Seasonality An Extension of the HEGY Approach in the Presence of Two Structural Breaks [PDF]

open access: yes
In this paper the HEGY testing procedure (Hylleberg et al. 1990) of analyzing seasonal unit roots is tried to be re-examined by allowing for seasonal mean shifts with exogenous break points. Using some Monte Carlo experiments the distribution of the HEGY

Extreme fire severity interacts with seed traits to moderate post‐fire species assemblages

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Premise Climate change is globally pushing fire regimes to new extremes, with unprecedented large‐scale severe fires. Persistent soil seed banks are a key mechanism for plant species recovery after fires, but extreme fire severity may generate soil temperatures beyond thresholds seeds are adapted to.
