From Empire to Aid: Analysing Persistence of Colonial Legacies in Foreign Aid to Africa

open access: yesJournal of International Development, EarlyView.
ABSTRACT For decades now, Western development agencies and donors have been castigated for their colonial biases in providing aid to Africa. It is well established that donors provide considerably more foreign aid to their former colonies relative to other countries.

Nonmonotonic Reasoning

open access: yesComputers & Mathematics with Applications, 1997
Nonmonotonic reasoning provides formal methods that enable intelligent systems to operate adequately when faced with incomplete or changing information. In particular, it provides rigorous mechanisms for taking back conclusions that, in the presence of new information, turn out to be wrong and for deriving new, alternative conclusions instead ...

Designing γ‐TiAl Alloys With Refined Twin‐Lamellar Microstructures via Machine Learning‐Driven Phase‐Field Methods

open access: yesMaterials Genome Engineering Advances, EarlyView.
Dual‐phase γ‐TiAl alloys with refined twin‐lamellar (RTL) structures exhibit optimal strength‐ductility synergy. Here, phase‐field simulations reveal composition‐stress‐dependent refined twin‐lamellar (RTL) microstructure evolution. Machine learning (CatBoost + NSGA‐III) trained on phase‐field images predicts optimal RTL‐stress‐composition design space.

17O Quadrupole Coupling Constants in Water

open access: yesMagnetic Resonance in Chemistry, EarlyView.
In water clusters, first‐nearest‐neighbor interactions (1A and 1D) provide the largest contribution and are well captured by an additive donor–acceptor scheme, with improved accuracy upon inclusion of hydrogen bond distance dependence. Second nearest neighbor (D and A*) effects introduce smaller but systematic negative corrections, restoring near ...

Efficient Computation of the Well-Founded Semantics over Big Data [PDF]

open access: yes, 2014
Data originating from theWeb, sensor readings and social media result in increasingly huge datasets. The so called Big Data comes with new scientific and technological challenges while creating new opportunities, hence the increasing interest in academia

Heavy‐Metal‐Free Colloidal Quantum Dots for Photocatalysis

open access: yesSmall, EarlyView.
Heavy‐metal‐free colloidal quantum dots provide sustainable photocatalytic platforms by combining tunable band structures, strong light absorption, and programmable surfaces/interfaces. This Review highlights how core/shell engineering, alloying, defect regulation, ligand design, and hybrid‐interface construction direct charge separation and ...

“When life was in the home circle” in the conditional reasonings of Fregean mad-humans and logical penalists

open access: yesСлово.ру: балтийский акцент
We advocate an idea that a necessary condition for a dispute about truth amounts not to the carriers of non-ideal logical thought, but to a variety of approaches to reconstructing the logical form of conditional reasoning, which implies diversification ...

Unveiling Van Der Waals Forces and Associated Hamaker Constants Across the Nanomaterial Landscape With Advanced Atomic Force Microscopy

open access: yesSmall Methods, EarlyView.
Van der Waals interactions are reviewed through the lens of advanced atomic force microscopy, highlighting recent progress in nanoscale quantification of Hamaker constants. Emerging methodologies enable high‐resolution mapping of intermolecular forces in 2D materials and biological systems, bridging experimental measurements with quantum‐informed ...

Defeasible Reasoning in Islamic Legal Theory

open access: yesInformal Logic
There is a common understanding among logicians today that nonmonotonic types of reasoning, such as defeasible or presumptive, can clearly warrant a rational acceptance of its conclusion.
