Local Order Is Not Enough: Synthetically Accessible Polymers Reveal the Role of Side‐chain Branching Point in Organic Solar Cell and Transistor Performance

open access: yesAdvanced Electronic Materials, EarlyView.
Systematic variation of the side‐chain branching point in a series of donor polymers reveals that moving the branch further from the backbone improves local crystal quality but reduces the overall degree of crystallinity, leading to progressively worse organic solar cell and transistor performance.

Reconfiguring Fresh Produce Supply Chains in Response to Drought Risk: Evidence From the U.S. Broccoli Market

open access: yesAgribusiness, EarlyView.
ABSTRACT Drought is among the most severe and persistent threats to food supply chains, and relocating production to less drought‐prone regions offers a strategy to reduce this risk. This is particularly relevant for fresh vegetables, which are highly water‐intensive, yet drought‐driven reconfiguration strategies remain understudied.

The emperor's new clones [PDF]

open access: yesNature Biotechnology, 2007
If regulators conclude that food from clones poses no more risk than food from other animals, the US and Europe could be on course for another biotech trade war.

Value of Information of Improved Traceability in Fresh Produce Markets

open access: yesAgribusiness, EarlyView.
ABSTRACT Traceability plays an important role in promoting a safe food supply by fostering transparent information exchange along the food supply chain. New technological innovations have the potential to improve traceability outcomes, as greater transparency along the food supply chain can aid in pinpointing precise origins of the contamination ...

Structured sorbents for Direct Air Capture: The impact of materials and chemicals on performance

open access: yesAIChE Journal, EarlyView.
Abstract Structured sorbents can efficiently process large air volumes required for Direct Air Capture (DAC), but their broad implementation is limited by challenges in producing reproducible and homogeneous materials. This work presents a robust procedure to graft amines onto monolithic sorbents and systematically investigates how CO2$$ {\mathrm{CO ...

Large‐Scale Machine Learning to Screen for Small‐Molecule Senolytics

open access: yesAdvanced Intelligent Discovery, EarlyView.
A consistent workflow underpins all experiments in this study. A dedicated model‐selection dataset first identifies optimal hyperparameters for each algorithm. Models are then trained and rigorously evaluated on independent sets of molecules using the senolytic ratio SR. Comprehensive hyperparameter exploration across SMILES representations, task types,

The function of imperial sanction and ministerial countersignature in Austrian legislation 1861-1918

open access: yesJournal on European History of Law, 2012
From 1861 to the end of the Austro-Hungarian monarchy two things were necessary to enact a new law: an act of parliament and the sanction by the emperor. Before a new law was published it had to be countersigned at least one minister.

Large Language Model‐Based Chatbots in Higher Education

open access: yesAdvanced Intelligent Systems, Volume 7, Issue 3, March 2025.
The use of large language models (LLMs) in higher education can facilitate personalized learning experiences, advance asynchronized learning, and support instructors, students, and researchers across diverse fields. The development of regulations and guidelines that address ethical and legal issues is essential to ensure safe and responsible adaptation

The Emperor of Austria as Supreme Commander 1867-1918

open access: yesJournal on European History of Law, 2013
After the “Ausgleich” of 1867 the Austro-Hungarian army got a complicated structure. Eventually the army was divided in three parts: the common army, the “Landwehr” in the Austrian half of the empire and the “Honved” in the Hungarian half.
