Charting the Path to Increased Oil Palm Output in Ghana Beyond Area Expansion: Technology or Managerial Capacity — Which Leads the Way?

open access: yesAgribusiness, EarlyView.
ABSTRACT This study sets out to investigate the prospects for raising oil palm output in sub‐Saharan Africa, particularly Ghana, without further expansion of cropland. Given global concerns about oil palm's role in deforestation and land use change, the focus is on enhancing productivity on existing farmlands.

Palladium‐Catalyzed Annulations of an Anti‐Bredt Olefin

open access: yesAngewandte Chemie, EarlyView.
We report metal‐catalyzed trappings of a [2.2.1]‐bridged bicyclic anti‐Bredt olefin (ABO). The methodology yields unusual heterocyclic products and is expected to prompt the further development of unconventional reactions, including metal‐catalyzed processes of ABOs and other strained olefins. ABSTRACT A famous class of alkene‐containing compounds that

Beyond Simple Mimicry: Next‐Generation Geometric Architectures and Future Paradigms in Small‐Molecule and Macrocyclic Peptidomimetics

open access: yesAngewandte Chemie, EarlyView.
Peptide‐to‐Small Molecule Paradigm: Peptidomimetics have evolved from simple mimicry toward drug‐like scaffolds supported by increasing clinical successes. This Perspective highlights the geometric design principles—linear repetition, convergent fusion, and cyclization—defining the next‐generation peptidomimetic architectures capable of targeting ...

XD-Bike: A Cross-Device Repository of Mountain Biking Routes

open access: yes, 2016
Despite the high level of interest in cross-device interaction, only few fully functional example applications exist. With XD-Bike, we built one of our own to not only showcase the use of our cross-device framework but also gather insights into the development process.

Public employees in South-Western Norway using an e-bike or a regular bike for commuting – A cross-sectional comparison on sociodemographic factors, commuting frequency and commuting distance

open access: yesPreventive Medicine Reports, 2019
Large-scale analyses on the travel behavior of e-bikes are scarce, and current knowledge regarding who the e-bike owners are is inconsistent. Also, commuters represent a relevant user group with an unexploited potential.

Lidar‐Based Object Tracking of Traffic Participants with Sensor Nodes in Existing Urban Infrastructure

open access: yesAdvanced Intelligent Systems, EarlyView.
This paper presents a lidar‐based sensor node design and a rule‐based state observer for edge‐based traffic participant tracking. Unlike other state‐of‐the‐art methods, this state observer enables real‐time, CPU‐only edge processing without relying on machine learning approaches.

Iridium‐Catalyzed Ionic Hydrogenation of Multi‐Aza Heterocycles

open access: yesAngewandte Chemie, EarlyView.
Saturated nitrogen‐containing heterocycles are ubiquitous in bioactive molecules and are thus attractive synthetic targets. A readily accessible cyclometalated iridium(III) complex reduces 14 different aromatic aza heterocycles to (partially)saturated multi aza‐heterocycles enlarging accessible chemical space while displaying high tolerance toward ...
