Bee keeping

open access: yes, 1905
Frequent inquiries from correspondents of the Department of Agriculture for information on matters pertaining to the culture of bees and particularly as to the conditions under which one may reasonably expect to meet with success in this pursuit, led to the preparation of this bulletin in July, 1897.

Data‐Driven Design of Scalable Perovskite Film Fabrication via Machine Learning–Guided Processing

open access: yesCarbon Energy, EarlyView.
Considering complex process parameters and poor reproducibility in perovskite thin film fabrication, this study uses machine learning to analyze and predict high‐dimensional process variables. The Random Forest model, identified as the most effective, can effectively analyze and rapidly predict optimal process parameters from extensive data.

Synthesis of a π‐Extended Phenazine Diimide Derivative and Characterization of Its Closed‐Shell Reduced States

open access: yesChemistry – A European Journal, EarlyView.
In this work, the synthesis and characterization of novel π‐extended phenazine diimides is reported. The derivatives undergo differential reduction to a dihydrophenazine or Meisenheimer form depending on the reaction conditions employed. The outcome of this work highlights the paramount importance of structural design in determining the nature of the ...

Hidden Markov graphical models with state‐dependent generalized hyperbolic distributions

open access: yesCanadian Journal of Statistics, EarlyView.
Abstract In this article, we develop a novel hidden Markov graphical model to investigate time‐varying interconnectedness between different financial markets. To identify conditional correlation structures under varying market conditions and accommodate shape features embedded in financial time series, we rely upon the generalized hyperbolic family of ...

Correlative Electron Paramagnetic Resonance Imaging and Atomic Force Microscopy of Lithium Deposited on Copper

open access: yesChemPhysChem, Volume 26, Issue 6, March 15, 2025.
The correlation of a spectroscopic (EPRI) and microscopic (AFM) technique is demonstrated for a sample of Li deposited on Cu. Areas of different morphology were analysed. The techniques complement each other's length scales as well as the information obtained from the sample.
