Overcoming the Phase Discontinuity Problem in RIS Optimization: A Robust and Scalable Phase‐Aware Deep Regression Framework via Hybrid CNN–LSTM Architecture

Advanced Intelligent Systems, Volume 8, Issue 9, September 2026.
The phase discontinuity problem—where the cyclic nature of phase angles causes catastrophic errors near the ±π boundary—is a fundamental obstacle in learning‐based reconfigurable intelligent surface (RIS) optimization. A phase‐aware hybrid CNN–LSTM framework resolves this by decomposing phase predictions into sine–cosine components, mapping circular ...

Repeatability and Parasitic Out‐of‐Plane Motion in Controlled Rocking Structures With Cylindrical Columns: Results From Triaxial Shake Table Tests

Earthquake Engineering &Structural Dynamics, Volume 55, Issue 11, Page 2930-2947, September 2026.
ABSTRACT Self‐centering rocking structures outperform conventional ones since they show zero post‐earthquake damage and excellent recentering; however, their applications remain limited due to concerns that rocking is extremely sensitive and nonrepeatable. This paper investigates the repeatability and parasitic out‐of‐plane motion of controlled rocking

Organisational Learning in Disaster Management Systems: Mechanisms, Barriers and Institutional Resilience

Journal of Contingencies and Crisis Management, Volume 34, Issue 3, September 2026.
ABSTRACT Disaster management systems (DMS) operate in contexts of uncertainty, urgency and complexity. Events such as the 2010 Haiti earthquake, the 2011 Fukushima Daiichi nuclear disaster and the COVID‐19 pandemic exposed how infrastructural breakdowns and weak coordination undermine institutional performance while accelerating innovation in digital ...

Evaluation of the Adequacy of Design Specifications for Nonstructural Components in a Reticular Structure

Earthquake Engineering &Structural Dynamics, Volume 55, Issue 10, Page 2132-2150, August 2026.
ABSTRACT Nonstructural components (NSCs) installed in large‐span reticular structures were frequently severely damaged during earthquakes, even when the primary structure remained intact. Existing seismic design specifications for NSCs were predominantly developed for upright structures such as multi‐storey buildings and offer no guidance for reticular
