Content-aware Density Map for Crowd Counting and Density Estimation

CoRR, 2019
Precise knowledge about the size of a crowd, its density and flow can provide valuable information for safety and security applications, event planning, architectural design and to analyze consumer behavior. Creating a powerful machine learning model, to employ for such applications requires a large and highly accurate and reliable dataset ...

Electrolyte Engineering Challenges and Opportunities for Next‐Generation Aqueous Ammonium‐Ion Batteries

Advanced Materials, EarlyView.
Aqueous ammonium‐ion batteries (AAIBs) face a hydrogen‐bond paradox: the HB network enables fast NH4+ transport but triggers water decomposition. This review dissects this dilemma, evaluates multiple electrolyte engineering strategies, and outlines four future directions for next‐generation AAIB design ABSTRACT Aqueous ammonium‐ion batteries (AAIBs ...

Mapping Correlated Environmental Landscapes in the Fluorescence Response of a Pyrenylated Charge‐Transfer Probe via Data‐Driven Nonlinear Regression

Advanced Materials Interfaces, EarlyView.
A pyrenylated donor–acceptor probe exhibits environment‐dependent fluorescence governed by intramolecular charge transfer, restricted molecular motion, and supramolecular organization. Nonlinear regression accurately reconstructs fluorescence responses to viscosity, temperature, concentration, and pH, while correlated parameter maps reveal hidden ...

Where Precursor Loading Stops Making a Difference: Resolving an Operational Infiltration Limit for Nanoparticle Synthesis Using Dual Quantification of Reverse Micelle Nanoreactors

Advanced Materials Interfaces, EarlyView.
A dual characterization strategy combining nanomechanical and mass measurements resolves a common operational loading threshold in reverse micelle nanoreactors. This transferable framework provides a rational strategy for optimizing precursor loading and nanoparticle synthesis, across template‐mediated fabrication systems.
