Mechanochromic Organic Materials: Molecular Mechanisms and Multidimensional Applications
Advanced Physics Research, Volume 5, Issue 2, February 2026.Mechanochromic (MC) organic materials change color in response to mechanical force. This review elucidates the molecular mechanisms (e.g., aggregation‐induced emission, AIE) and explores their multidimensional applications in sensors, anti‐counterfeiting, biomedical devices, and structural health monitoring, providing a roadmap for future smart ...

Do Adverse Events Influence Time Preferences? Evidence From Smallholder African Farmers
Journal of Agricultural Economics, Volume 77, Issue 1, Page 130-155, February 2026.ABSTRACT Time preferences play a critical role in the agri‐food value chains of low‐income countries, impacting the choices of local operators, including innovation uptake. This paper assesses the association between smallholder farmers' individual characteristics, their exposure to diverse adverse events, and their intertemporal choices using in‐the ...

Fractional norms and quasinorms do not help to overcome the curse of dimensionality
, 2020 The curse of dimensionality causes the well-known and widely discussed problems for machine learning methods. There is a hypothesis that using of the Manhattan distance and even fractional quasinorms lp (for p less than 1) can help to overcome the curse ...

Beyond National Currency: The Plurality of Early Modern Money
History Compass, Volume 24, Issue 1, February 2026.ABSTRACT Diversity in money leaps at historians of early modern societies, whether they analyse account books, legal documents, travelogues and diaries, or try to make sense of a sum casually mentioned in a source from the period. The plurality of money objects contrasts with the homogeneous, singular currencies imposed by nation‐states in the 19th and

On the Persistence of Clustering Solutions and True Number of Clusters in a Dataset
, 2018 Typically clustering algorithms provide clustering solutions with prespecified number of clusters. The lack of a priori knowledge on the true number of underlying clusters in the dataset makes it important to have a metric to compare the clustering ...

Sustainable polypropylene chair: A life cycle assessment and cost analysis of industrial production
Environmental Progress &Sustainable Energy, Volume 45, Issue 1, January/February 2026.Abstract Due to their multiple properties, including flexibility, lightness, and strength, thermoplastics are an essential material in the development of processes at both industrial and domestic levels. However, thermoplastics are often derived from polymers synthesized using non‐renewable petroleum resources. This has environmental consequences.

Economic Anthropology, Volume 13, Issue 1, January 2026.ABSTRACT The khipu knotted string records in the ancient Andes were accounting systems, but they did not indicate any concepts of commensurability or exchange value. They were not incipient money; instead, monetized commerce appears to have predated the economic organization of the Inca society. The article begins by tracing the emergence of coinage in

Minimum Density Hyperplanes [PDF]
, 2016 Associating distinct groups of objects (clusters) with contiguous regions of high probability density (high-density clusters), is central to many statistical and machine learning approaches to the classification of unlabelled data.

Technocrats, Reputation, and Responsiveness in Policy Explanation
Governance, Volume 39, Issue 1, January 2026.ABSTRACT In contemporary democracies, independent technocratic bodies take many key policy decisions. The organizations are meant to avoid traditional policy responsiveness, but still have processes in place to take into account societal views. Our study analyzes how pressure on technocratic bodies affects the audience orientation of their policy ...
