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.

Now You See Them, Now You Don't: Understanding New Hire Ghosting and Its Antecedents

Human Resource Management Journal, EarlyView.
ABSTRACT New hire ghosting, in which applicants accept an offer and then quit before their first day without notice, is an emerging and consequential staffing phenomenon. Drawing on job embeddedness theory, we conceptualize new hire ghosting as a form of pre‐entry withdrawal influenced by dispositional risk and the fragile fit, links, and sacrifice ...

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.

Party Democracy in a Fractured System

IPPR Progressive Review, EarlyView.
ABSTRACT This paper examines the fragmentation of Britain's party system as a crisis of party democracy, and argues that electoral reform is necessary to return to a point where parties can still do the representative work on which democratic government depends. The mass‐party model and class cleavages that once underpinned stable party government have

A Procedure to Optimize Reed Type Valves Considering Efficiency and Bending Fatigue [PDF]

, 2012
Reed valves are the most common type of valves used in small compressors due to their simplicity and low cost. Such valves greatly affect the compressor volumetric and isentropic efficiencies and their suitable design is also crucial for reliability ...

Ultrasonic Vibration Assisted Laser Processing: A Hybrid Paradigm for Extreme Surface Enhancement

Rare Metals, Volume 45, Issue 10, October 2026.
ABSTRACT Traditional laser processing techniques offer many advantages, but they often encounter limitations such as heat‐affected zones, recast layers, residual tensile stresses, and poor surface finish. The integration of ultrasonic vibration (UV) presents a promising hybrid approach to overcome these challenges by introducing beneficial effects like

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.
