Mars Rover Sample Return: A sample collection and analysis strategy for exobiology [PDF]
For reasons defined elsewhere it is reasonable to search for biological signatures, both chemical and morphological, of extinct life on Mars. Life on Earth requries the presence of liquid water, therefore, it is important to explore sites on Mars where ...

How 1st‐Tier Suppliers Respond to Green Public Procurement Policies: An Empirical Analysis
Corporate Social Responsibility and Environmental Management, EarlyView.ABSTRACT This article analyses how 1st‐tier suppliers to public organisations respond operationally to Green Public Procurement (GPP) policies. Through a multiple case study of 12 Italian firms operating in different sectors, we develop a classification of suppliers' responses, identifying two interrelated macro‐types: internal operations realignment ...

Warming summers limit reindeer grazing, weakening herbivory pressure in the mountain tundra
Ecography, EarlyView.Climate change is predicted to alter species interactions by exposing ecosystems to increasingly frequent and intense warm spells. In the mountain tundra, grazing by large herbivores, particularly reindeer, can limit shrub expansion and preserve Arctic plant diversity.

The real-time control of planetary rovers through behavior modification [PDF]
It is not yet clear of what type, and how much, intelligence is needed for a planetary rover to function semi-autonomously on a planetary surface.

‘SiteTool': a ‘Shiny' application for field site selection and evaluation
Ecography, EarlyView.Field studies are fundamental to ecological research, yet many studies rely on unspecified or convenience‐based methods for site selection, potentially introducing bias that can compromise research results. Remote‐sensing data provides a quantitative way to evaluate potential sites without expensive pilot visits; however, interacting with spatial data ...

Dual role of spreading depolarization in an epileptic focus
Epilepsia, EarlyView.Abstract Objective Spreading depolarizations (SDs) are often associated with epileptic discharges. Although SDs are traditionally thought to contribute to postictal depression and termination of epileptic discharges, seizures may also occur during SDs or may even follow SDs, suggesting that interactions between SD and seizures are more complex.
