Solution‐Processed Mn‐Doped 2d Perovskite Wavelength Shifters for Noble‐Liquid Photon Detection

Advanced Functional Materials, EarlyView.
Solution‐processed Mn2+‐doped PEA2PbBr4 two‐dimensional perovskite films are demonstrated as large‐area wavelength shifters for noble‐liquid photon detectors. Mn2+ incorporation introduces a broad emission band at ∼620 nm with a large Stokes shift, suppressing self‐absorption and matching SiPM sensitivity.

3D Bioprinted Glioblastoma Multiforme Models: How the Extracellular Matrix Glycosignature Influences Drug Response

Advanced Functional Materials, EarlyView.
Aberrant glycosylation in the glioblastoma tumor microenvironment drives therapeutic resistance. Here, a 3D bioprinted model was engineered by incorporating α‐NeuNAc‐(2→3)‐β‐D‐Gal‐ and chondroitin sulfate. Combined multiplex immunofluorescence and synchrotron‐based nanoCT analysis revealed that glycan‐matrix interactions dictate specific drug‐escape ...

Complementarity and Substitutability of Investment Strategies

Journal of Evolutionary Economics
Abstract This study quantifies the impact of a reallocation of capital between investment strategies on the cross-section of their performance when capital flows are the sole transmission channel. The main finding of our counterfactual analysis is that capacity of strategies, correlation of returns and the cyclical nature of investment ...

ADAPTIVE INVESTMENT STRATEGIES FOR PERIODIC ENVIRONMENTS [PDF]

Advances in Complex Systems, 2008
In this paper, an adaptive investment strategy for environments with periodic returns on investment is presented. In this approach, an investment model is considered where the agent decides at every time step the proportion of wealth to invest in a risky asset, keeping the rest of the budget in a risk-free asset.

Self‐Cooling Molecular Spin Qudits

Advanced Materials, EarlyView.
A material made of [GdEr] molecular dimers can encode a qudit and perform as a magnetic refrigerant. Microwave resonant pulses coherently manipulate its 16 spin states, while direct demagnetization measurements cool the material and a device down to temperatures below 1 K.
