It is not often that a comet defies one of the most fundamental visual cues in astronomy-but 3I/ATLAS has done exactly that.

At the heart of this research is a miniaturized transcranial optogenetic neural stimulator. This innovative device operates wirelessly, enabling real-time modulation of cortical activity. Key features ...

Division of Fluid Dynamics, Department of Mechanics and Maritime Sciences, Chalmers University of Technology, Gotheburg, Sweden Industrial plate heat exchangers for cooling of complex, condensing gas ...

Over the past decades, engineers have introduced numerous technologies that rely on light and its underlying characteristics. These include photonic and quantum systems that could advance imaging, ...

Numerical modeling of galactic cosmic rays (GCRs) penetration through the heliosphere to the vicinity of the Sun is considered. Galactic cosmic rays are charged particles with energies exceeding 10 ...

Doing more with less in electronics often means improving power density. One of the new areas garnering attention involves applying a variety of advanced modulation techniques, including PWM and space ...

ABSTRACT: The menstrual cycle has been a topic of interest in relation to behavior and cognition for many years, with historical beliefs associating it with cognitive impairment. However, recent ...

Equations of the form du/dt = g(u(t), u(h(t))) arise in a number of scientific contexts. The authors point out some interesting properties of the solution of u′(t) = -u(t - 1 - k sin &ohgr;t) + sin at ...

Abstract: Pulse width modulation is widely used in modern engine control systems. With this control method, power is regulated by periodically turning on and off the load for a specified period of ...

Impact Statement: This paper numerically analyzes the modulation characteristics of a hybrid-modulation laser integrated with a passive waveguide. In this paper we confirmed that the 3-dB intrinsic ...
