Ligand‐Mediated Shape Engineering of SWIR InAs Colloidal Quantum Dots for Photodetector Applications

Advanced Materials, EarlyView.
The table of contents: A robust ligand‐engineering strategy is introduced for SWIR InAs CQDs synthesized from amino‐arsine precursors. Bulky OA ligands induce controlled shape evolution, allowing access to >1700 nm absorption under mild conditions. Halide‐based inkification enables photodetectors with 19.1% EQE at 1300 nm and detectivity exceeding 1010

Regulatory Sentiment and Economic Performance

KDI Journal of Economic Policy, 2023
Regulatory sentiment refers to the market's subjective evaluation of regulatory reform and is one of the most widely adopted indicators to those charged with implementing and diagnosing regulatory policies. The use of regulatory sentiment in advanced analysis has become universal, albeit it is often limited due to difficulties in articulating ...

Expectations, Economic Uncertainty, and Sentiment

Revista de Administração Contemporânea, 2022
ABSTRACT Objective: this article aims to help unravel if and how economic uncertainty interacts with the informational structure of sentiment. Methods: the empirical strategy is based on a non-linear and non-parametric causality test to investigate the interaction between variables as distributions.

The Influence of Mesoscale Particle Structure on the Electrode Degradation and Resultant Electrochemistry of Lithium Ion Cells With Nickel Rich Lithium Nickel Manganese Cobalt Oxide Positive Electrodes

Advanced Materials Technologies, EarlyView.
Milled polycrystalline NMC811 cathode (MPC NMC) with smaller secondary particle and higher surface area had 1) greater cathode tortuosity, 2) reduced surface Ni on the cycled MPC cathodes consistent with surface reconstruction, and 3) increased Ni deposition from cathode‐anode crosstalk, manifesting in lower functional capacity and higher impedance ...

Evaluation of News Sentiment in Economic Activity Forecasting

ASEC 2022, 2022
Natural language processing is a rapidly expanding field of artificial intelligence, the main goal of which is linguistics. This field allows various mathematical/computer science techniques to be applied to natural language processing. Sentiment analysis is one of the most common tasks that is solved based on natural language processing.

Auditory–Tactile Congruence for Synthesis of Adaptive Pain Expressions in RoboPatients

Advanced Robotics Research, EarlyView.
In this work, we explore auditory–tactile congruence for synthesizing adaptive vocal pain expressions in robopatients. Using a robopatient platform that integrates vocal pain sounds with palpation forces, we conducted 7680 trials across 20 participants.

Consensus Formation and Change are Enhanced by Neutrality

Advanced Science, EarlyView.
Neutral agents are shown to enhance both the formation and overturning of consensus in collective decision‐making. A general mathematical model and experiments with locusts and humans reveal that neutrality enables robust consensus via simple interactions and accelerates consensus change by reducing effective population size.

Enhancing Biogenic Formic Acid Production in the Modified OxFA Process by Acetonitrile Addition

Advanced Science, EarlyView.
In this study, the beneficial effect of using acetonitrile as a co‐solvent in the modified OxFA process is shown, outperforming methanol, demonstrating improved reaction kinetics combined with high selectivity for the HPA‐2 (H5PV2Mo10O40) catalyzed oxidation of xylose to FA.
