Activatable smart contrast agents for photoacoustic imaging

Smart Molecules, EarlyView.
This review highlights recent advances in smart activatable photoacoustic imaging (PAI) contrast agents, which dynamically modulate their optical properties in response to external stimuli or microenvironmental cues. It discusses their molecular design, activation mechanisms, biomedical applications, and future prospects for clinically tailored use ...

Identification of invisible damage in prestressed concrete bridges—A demonstrator case using coda wave interferometry

Structural Concrete, EarlyView.
Abstract During their life cycle, prestressed concrete bridges are prone to wire breaks of their tendons due to fatigue or stress corrosion cracking. However, not all structures show visible cracking on the surface, which would provide timely warning of otherwise invisible damage. Brittle failure may occur.

Academics’ Career Motivations and External Engagement Activity Amid Conflicting Identifications: An Employee Engagement Perspective

British Journal of Management, EarlyView.
Abstract This paper examines the motivational foundations of academics’ external engagement within the evolving context of the entrepreneurial university. While prior research has explored specific forms of academic entrepreneurship, broader engagement with external organizations has only recently been recognized as both entrepreneurial and value ...

Reassessing Heidegger on Van Gogh: Artistic Experience as Contextual Displacement

European Journal of Philosophy, EarlyView.
Abstract This article offers a novel account of Heidegger's long‐debated discussion of a painting of shoes by Van Gogh in ‘The Origin of the Work of Art’. I argue that the Van Gogh episode is best understood as a carefully staged textual enactment of Heidegger's conception of artistic experience, properly construed.

Leadership Under Risk: Male Vervet Monkeys' (Chlorocebus pygerythrus) Roles in Group Progression Across Potentially High‐Risk Terrain

Ethology, EarlyView.
Male vervet monkeys were more likely to lead group progressions than females or juveniles, especially during potentially riskier crossing situations, i.e., rivers. Dominant males who had not yet sired offspring were the most likely to lead progressions.

Research on Fault Diagnosis Method of Reciprocating Compressor Based on RSSD and Optimized Parameter RCMDE

Applied Sciences
As for the fault diagnosis process of a reciprocating compressor, vibration signals are often non-stationary, nonlinear, and multi-coupled, which makes it difficult to conduct effective fault information extraction.

Vibration Analysis of a Single-Cylinder Reciprocating Compressor considering the Coupling Effects of Torsional Vibration

Shock and Vibration, 2019
A piston slap is one of the main vibration sources of the reciprocating machinery. Much work has been done in this field, most of which was based on a constant rotating speed.
