The Problem of Transforming Values into Prices

Revista de Ciencias Economicas, 2011
The object of this paper is to describe and analyze in a formal and integrated way the alternative solutions proposed to the problem of transforming labor values into prices. Considering that the literature on this topic is sometimes diffused, this paper

Pre‐Refinement Prediction of Dopant Site Occupancy in M‐Type Hexaferrites via Hierarchical and Uncertainty‐Aware Machine‐Learning

Advanced Science, EarlyView.
Refined data are extracted from CIF files to construct a hierarchical machine‐learning framework integrating sublattice classification, Fe‐site occupancy prediction, and reliability assessment. External validation yields 96% accuracy for sublattice classification and a macro mean absolute error of 0.0584 for Fe‐site prediction.

Blocking Honeybee Preference for Neonicotinoids by Interfering With Dopamine Signaling

Advanced Science, EarlyView.
Honeybees (Apis mellifera) paradoxically prefer nectar containing the harmful neonicotinoid thiamethoxam. This preference is associated with transient brain dopamine elevation during proboscis extension reflex (PER) responses and active feeding, and is reduced by the dopamine receptor antagonist fluphenazine.

A CT Lesion Foundation Model for Non‐Invasive Assessment of Hepatocellular Carcinoma Aggressiveness and Prediction of Recurrence Risk

Advanced Science, EarlyView.
A computed tomography lesion foundation model, built by sequential self‐supervised pretraining on generic and hepatocellular carcinoma‐specific lesion images, non‐invasively assesses microvascular invasion and pathological grade from contrast‐enhanced CT and stratifies postoperative recurrence risk.

Electrocatalytic Urea Synthesis From CO2 and N2/NO3−: Bridging Catalyst Activity, C–N Coupling Kinetics, and Industrial Applicability

Advanced Science, EarlyView.
This review compares NO3− + CO2 and N2 + CO2 electrocatalytic urea synthesis in feedstock properties, catalyst design, C–N coupling mechanisms, performance optimization, and engineering applicability. The two systems correspond to a near‐term deployable route and a long‐term green synthesis goal, respectively.

Matrix Stiffness Promotes Tumor Metastasis by Triggering Recycling Endosome‐Mediated YY1 Nuclear Translocation and Transcriptional Activity

Advanced Science, EarlyView.
In stiff extracellular matrix (ECM), integrin αVβ3 transduces mechanical cues of ECM stiffness to promote recycling endosome formation, creating a signaling platform for yin yang 1 (YY1)/p21‐activated kinase 4 (PAK4) binding, but not in soft ECM. Then, this triggers PAK4‐mediated YY1 phosphorylation at S118, subsequent YY1 nuclear translocation and ...

SynAtlas: A Safe and Versatile Platform for Rapid Organ‐Scale Tissue Clearing and 3D Atlas Mapping

Advanced Science, EarlyView.
An orthogonal synergy design principle integrates lipid solubilization, protein hydration modulation, and refractive‐index matching within a unified aqueous clearing system. This modular strategy enables rapid, low‐hazard, and broadly compatible tissue clearing while preserving molecular signals, supporting multiscale three‐dimensional imaging across ...

Living Electronics: Microbial Metabolism as Batteries, Resistors, and Capacitors

Advanced Electronic Materials, EarlyView.
Three microorganisms are assigned the three elementary roles of a circuit on one sheet of paper. Dormant Bacillus subtilis spores germinate to switch the power source on; a photosynthetic Synechocystis biofilm sets resistance by the color and intensity of light; and a respiring Shewanella oneidensis biofilm stores charge. Together they form a printable

Farmers' Preferences for Fossil‐Free Mineral Nitrogen Fertilizers: Role of Prices, Climate, Production Origin, and Identity

Applied Economic Perspectives and Policy, EarlyView.
ABSTRACT Disruptions in global fertilizer markets and climate targets have increased interest in fossil‐free mineral nitrogen fertilizers. This study examines farmers' preferences for conventional (fossil‐based) and fossil‐free fertilizers using a labeled discrete choice experiment with 211 Swedish farmers.

Heterogeneity of Farmer Preferences Towards Collective Agri‐Environmental Schemes: A Latent Class Analysis for Biodiversity Conservation in Switzerland

Applied Economic Perspectives and Policy, EarlyView.
ABSTRACT Collective agri‐environmental schemes offer a promising approach to improve biodiversity promotion in agriculture by providing landscape connectivity. However, how to design these schemes to foster participation in the presence of farmers' heterogeneous preferences and perceived transaction costs remains an open question.
