Bifurcation analysis and new waveforms to the first fractional WBBM equation

Scientific Reports
This research focuses on bifurcation analysis and new waveforms for the first fractional 3D Wazwaz–Benjamin–Bona–Mahony (WBBM) structure, which arises in shallow water waves.

Rearrangement Towards Stability: Plastic Shakedown in Granular Materials Under Thermal Cycles

International Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.
ABSTRACT Granular materials are routinely subjected to thermal cycling due to natural and anthropogenic phenomena. Despite the ubiquity of this occurrence and its relevance for science, engineering, and technology, the long‐term thermo‐mechanical response of granular materials to repeated heating and cooling remains poorly understood.

Sculpting of Exoplanetary Systems Driven by a Misaligned Disk and Stellar Oblateness: Origin of Perpendicular Orbits in HD 3167

The Astrophysical Journal Letters
A significant proportion of exoplanets have been detected with highly tilted or even polar orbits relative to their host stars’ equatorial planes. These unusual orbital configurations are often linked to postdisk secular interactions among multiple ...

Stratospheric influence on tropical cyclone evolution

Quarterly Journal of the Royal Meteorological Society, EarlyView.
We developed a metric based on moist static energy to detect and quantify the intrusion of stratospheric air into the inner core of tropical cyclones. High‐resolution numerical simulations show that this stratospheric interaction forms warm anomalies (high‐level warm cores) in the upper troposphere.

Structural changes in the interannual variability of extreme autumn precipitation in eastern Spain and the weakening of synoptic forcing

Quarterly Journal of the Royal Meteorological Society, EarlyView.
Total autumn precipitation in eastern Spain remains stable between 1950 and 2024, masking a substantial internal redistribution between ordinary and extreme rainfall. While torrential precipitation (Rp95) increases and ordinary precipitation (Ro) decreases, the extreme contribution index (Cext) shows a significant positive trend and a structural shift ...

Study on the smoke mass flow in T-shaped tunnel fire

Case Studies in Thermal Engineering
Smoke mass flow rate (SMFR) is an important factor for smoke control in tunnel fire. The presence of bifurcation structure can lead to the flow redistribution and distinctive characteristics.

Spectral Submanifolds of Delay Systems: Control in Continuous and Discrete Time

International Journal of Robust and Nonlinear Control, EarlyView.
ABSTRACT This paper presents both continuous‐time and discretization‐based approaches for constructing spectral submanifolds (SSMs) for time delay systems. The continuous‐time approach built upon sun–star calculus, reformulates the governing delay differential equation (DDE) as an operator differential equation (OpDE).

Nested Selves: Self‐Organization and Shared Markov Blankets in Prenatal Development in Humans

Topics in Cognitive Science, EarlyView., 2023
Abstract The immune system is a central component of organismic function in humans. This paper addresses self‐organization of biological systems in relation to—and nested within—other biological systems in pregnancy. Pregnancy constitutes a fundamental state for human embodiment and a key step in the evolution and conservation of our species. While not
