Market power and the need for regulation in the German airport market [PDF]

With the increasing profit orientation of German airport operators the question as to weather they possess market power is gaining more importance. Whereas there have been some studies about the degree of market power of individual airports in countries ...

Human–wildlife coexistence and social context: Evidence from farmer communities in southern Sri Lanka

People and Nature, EarlyView.
Abstract Studies on human–wildlife interactions (HWI) often focus on conflict mitigation studies, thus overlooking underlying factors that influence community decisions to coexist with wildlife. To address this knowledge gap, we collected empirical evidence of how community interactions with wildlife are shaped by their social contexts.

A safe reinforcement learning approach for autonomous navigation of mobile robots in dynamic environments

CAAI Transactions on Intelligence Technology, EarlyView., 2023
Abstract When deploying mobile robots in real‐world scenarios, such as airports, train stations, hospitals, and schools, collisions with pedestrians are intolerable and catastrophic. Motion safety becomes one of the most fundamental requirements for mobile robots.

Modeled Subsidence of Permafrost Terrain 2025–2050: North‐Central Alaska

Permafrost and Periglacial Processes, EarlyView.
ABSTRACT A large fraction of the Alaska terrain is underlain by regolith that contains excess ice (ice that in volume exceeds the natural pore space). Possible loss of excess ice would lead to ground subsidence, which in turn would disturb and destabilize the ground surface.

Capsicum chinense as an African traditional vegetable: Culture, resilience, and opportunity

PLANTS, PEOPLE, PLANET, EarlyView.
Capsicum chinense is central to everyday diets, cultural identity, and smallholder livelihoods across Sub‐Saharan Africa, yet remains overlooked in agricultural research and policy. This paper reframes C. chinense as a traditional, climate‐resilient vegetable shaped by centuries of farmer stewardship and cultural selection.

Accidental plant poisonings in France: Lessons from a decade of national toxicovigilance

PLANTS, PEOPLE, PLANET, EarlyView.
Accidental plant poisonings reveal how modern societies are losing everyday botanical knowledge once central to food and health safety. By analyzing a decade of French toxicovigilance data, this study shows that most severe cases arise from plant misidentification or misguided self‐medication.

The evaluation of boundary‐layer turbulence in high‐resolution numerical weather prediction simulations using Doppler lidar

Quarterly Journal of the Royal Meteorological Society, EarlyView.
A new method compares both kilometer and sub‐kilometre weather model simulations with Doppler lidar observations to assess the representation of boundary‐layer turbulence. While bulk boundary‐layer properties are well represented, vertical velocity variance is strongly underestimated in both simulations.

The physical and synoptic‐dynamical differences between warm days, hot days, and heatwaves during summer in Victoria, Australia

Quarterly Journal of the Royal Meteorological Society, EarlyView.
During the day, there is composite mean cold advection in the boundary layer on warm days (WDs), hot days (HDs) and heatwaves (HWs). There is weaker surface‐sensible heating on HDs and HWs. A nocturnal jet advects warm air on HDs and HWs. There is a strong and slow‐moving upper‐level anticyclone on HWs.

Error in ERA5 2‐m temperature identified using GraphCast

Quarterly Journal of the Royal Meteorological Society, EarlyView.
We identify a recurrent error in ERA5 2‐m temperature over the Ethiopian Highlands that occurs predominantly at 0600 UTC on ≈7%$$ \approx 7\% $$ of dates. The artefact is caused by the 2D optimal‐interpolation scheme assimilating temporally displaced surface reports (e.g., 0900 UTC) into the 0600 UTC analysis.

An Algorithm for the Nucleolus of Airport Profit Problems [PDF]

Airport profit games are a generalization of airport cost games as well as of bankruptcy games.In this paper we present a simple algorithm to compute the nucleolus of airport profit games.In addition we prove that there exists an unique consistent ...
