Fritz Scheffer Under National Socialism: Assessing His Political Involvement

open access: yesJournal of Plant Nutrition and Soil Science, EarlyView.
ABSTRACT Aims This article examines the role of soil scientist Fritz Scheffer (1899–1979) under National Socialism and offers a critical assessment of his scientific, institutional, and political positioning between 1933 and 1945. It asks how Scheffer shaped his career within the tension between disciplinary specialization, political expectations, and ...

A novel approach for in situ benthic habitat characterization

open access: yesLimnology and Oceanography: Methods, EarlyView.
Abstract Habitat heterogeneity is a key driver of temporal and spatial variability of subtidal marine benthic biodiversity. However, this makes it a challenging environment in which to measure and quantify the factors driving biodiversity in a consistent manner.

Clinical and Molecular Features of BAP1‐Mutated Meningiomas: Case Series

open access: yesMolecular Carcinogenesis, EarlyView.
ABSTRACT BRCA1‐associated protein 1 (BAP1)‐deficient meningiomas represent a clinically and molecularly distinct subgroup with variable histology and aggressive behavior that may not be fully captured by current grading criteria. The clinical spectrum of BAP1 alterations in meningiomas, including both somatic and germline contexts, remains incompletely

Leveraging Public Transit for Robotic Deliveries: A Column Generation Approach

open access: yesNaval Research Logistics (NRL), EarlyView.
ABSTRACT Autonomous mobile robots (AMRs) are small, electric, wheeled vehicles that operate at pedestrian speeds. In the last‐mile delivery service considered in this study, a fleet of AMRs is deployed across multiple recharging depots within a service area, from which they depart to perform point‐to‐point deliveries. We consider an operational setting

Energy Optimization Models for the Locomotive Assignment Problem

open access: yesNetworks, EarlyView.
ABSTRACT Reducing energy consumption is a key objective in transportation. Using detailed infrastructure data, this study introduces the Green Locomotive Assignment Problem (GLAP) to minimize energy consumption in railway operations by efficiently assigning locomotives to pre‐scheduled trains.

A Two‐Stage Optimization Approach for Selecting Electric‐Flight Airports

open access: yesNetworks, EarlyView.
ABSTRACT The decarbonization of short‐haul air transport has gained increasing attention, with electric aircraft emerging as a promising alternative to conventional short‐haul aviation. However, given the substantial investment anticipated for the necessary infrastructure, a strategic and globally coordinated selection of airports is imperative.

Interplanetary frontiers: terraforming from an invasion science perspective

open access: yesOikos, EarlyView.
The pursuit of a multi‐planetary existence represents one of humanity's greatest frontiers. If applied justly, it offers an opportunity to extend its civilization's lifespan amid escalating sustainability crises on Earth. One approach increasingly gaining traction is terraforming, a hitherto theoretical ecological and evolutionary experiment revolving ...

The magnitude and economic replacement value of wild meat obtained from ‘recreational’ big game hunting in the United States

open access: yesPeople and Nature, EarlyView.
Abstract Meat production has notable benefits for food security, nutrition and various production economies, but has elicited substantial negative environmental impacts. Recreational hunting provides an alternative to agricultural meat production for over 24 million hunters worldwide.

Development of the model of forced-exhaust ventilation for passenger carriages

open access: yesEastern-European Journal of Enterprise Technologies, 2016
The behavior analysis of the model of forced-exhaust ventilation for the passenger compartment carriage, based on the principle of similarity with electric circuits is performed. For quality indicators of the control object, the parameters of resistance and relative inductances determining the aerodynamic inertia of ducts and compartments are included ...
