Intergalactic Wandering Stars in the Local Universe: Theoretical Predictions for Their Distance and Luminosity Distribution

Jia-Hui Wang, Maosheng Xiang, Ji-Feng Liu • The Astrophysical Journal (2025)

Intergalactic wandering stars (IWSs) within 10 Mpc remain a poorly explored area of astronomy. Such stars, if they exist, are supposed to be wandering objects as they are not bound by the gravitational potential of any galaxy. We set out to...

Potential quantum advantage for simulation of fluid dynamics

Xiangyu Li, Xiaolong Yin, Nathan Wiebe, Jaehun Chun et al. • Physical Review Research (2025)

Numerical simulation of turbulent fluid dynamics needs to either parametrize turbulence—which introduces large uncertainties—or explicitly resolve the smallest scales—which is prohibitively expensive. Here, we provide evidence through analy...

Effect of Duffing nonlinearity on squeezing in a classical parametric amplifier in the unstable regime

Tomoki KANDA, Hiroshi YABUNO • Mechanical Engineering Journal (2026)

In quantum information processing, control of quantum entanglement is of central importance, particularly for applications in quantum computing. One established method for generating entanglement is squeezing, which exploits the uncertainty...

A Behavioral SIQR-B Model for Cholera Transmission: Impact of Adaptive Risk Perception on Disease Dynamics

Pedro Pablo Cárdenas Alzate, Jaime Alberto Echeverri Franco, Jacobo Echeverri Hoyos • Epidemiologia (2026)

Background/Objectives: Cholera remains a major public health problem, particularly in regions with limited access to safe drinking water and sanitation. Traditional compartmental models may underrepresent adaptive human behavioral responses...

Regional observability of distributed systems

M. Amouroux, A. El Jai, El Hassan Zerrik • International Journal of Systems Science (1994)

The aim of this paper is to develop the concept of regional observability for distributed systems. This original concept is closer to practical considerations since it only requires the observation of the state on a given subregion. We show...

Ultrahigh-peak-power laser pulse compression by a double-smoothing grating compressor

Renjing Chen, Wenhai Liang, Yilin Xu, Shuman Du et al. • High Power Laser Science and Engineering (2025)

Spatial intensity modulation in amplified laser beams, particularly hot spots, critically constrains attainable pulse peak power due to the damage threshold limitations of four-grating compressors. This study demonstrates that the double-sm...
