Bifunctional Competitive Structure of Biomass Carbon‐Derived Metacomposites for Tunable ε′‐Near‐Zero and ε′‐Negative Responses

Rare Metals, EarlyView.
ABSTRACT Regulating negative parameters of metacomposites is mainly limited by their unclear mechanisms, which affects their practical applications in new sensing, communication, electromagnetic (EM) protection and other fields. This work proposes a dual‐functional competitive design strategy based on the waste corncob‐derived carbon/polyaniline ...

Surface‐Embedded Ag@Multilayer Graphene for Photothermal‐Enhanced Superhydrophobic Anti‐Icing Coatings

Rare Metals, EarlyView.
ABSTRACT Harnessing solar energy for self‐heating presents an effective strategy to suppress surface ice formation. In this paper, we fabricated nano‐silver‐modified multilayer graphene sheets (Ag@MGs) that integrate photothermal and superhydrophobic properties for anti‐icing applications.

Sonified Signals From a Compact FT‐ICR Instrument: A Feasibility Study. I—Data Mapping to an Equal‐Tempered Chromatic Scale

Rapid Communications in Mass Spectrometry, EarlyView.
ABSTRACT Rationale Ions trapped within a Penning cell (ICR) travel periodic orbits whose frequencies are dependent on their mass‐to‐charge ratio and the value of the magnetic field passing through the trap. Fourier transformation (FT‐ICR) decomposes the signal induced in the detection circuit by the rotation of the ions in the cell after the ...

Non‐Invasive Brain Stimulation in Chronic Pain: Current Evidence, Network Perspectives and Paths to Personalization

Sensory Neuroscience, EarlyView.
Chronic pain reflects maladaptive network interactions across sensory, salience/affective, and descending modulatory pathways. We review evidence for non‐invasive brain stimulation—rTMS, tES, and low‐intensity focused ultrasound—highlighting modest, variable, and often short‐lived analgesic effects under conventional protocols.

Navigating uncertainty in a nascent ecosystem: How shifting cognitive frames influence an incumbent firm's platform scope strategies

Strategic Management Journal, EarlyView.
Abstract Research Summary We examine how an incumbent firm navigates internal and external uncertainties when entering a nascent platform ecosystem. Drawing on a longitudinal study of a large telecommunication firm's transition into an evolving IoT ecosystem, we advance a cognitive perspective on platform strategy.
