A 3D nanowire‐network SERS substrate with robust adhesion is developed, featuring pronounced z‐direction optical activity, ultralow detection limit (1.5 × 10−13 M), and excellent signal uniformity (RSD < 10%). Enabled by enhanced light scattering, increased optical density of states, and structural reinforcement, the substrate demonstrates stable, high‐

Non-Markovian stochastic processes and the wave-like properties of matter
A non-markovian stochastic model is shown to lead to a universal relationship between particle's energy, driven frequency and a frequency of interaction with the medium.

Abstract String theory has strong implications for cosmology, implying the absence of a cosmological constant, ruling out single‐field slow‐roll inflation, and that black holes decay. The origins of these statements are elucidated within the string‐theoretical swampland programme.

The Prediction of Short‐Term Atmospheric Density in Lower Thermosphere
Abstract Accurate short‐term prediction of atmospheric density in the lower thermosphere (85–125 km) is essential for precise orbit determination and satellite drag mitigation, particularly during geomagnetic storms. Although physics‐based models such as NRLMSIS 2.1 provide empirical estimates, their effectiveness is limited under extreme space weather.

Short‐Term Variability of Jupiter's Satellite Footprints as Spotted by JWST
Abstract We present the main Alfvén wing (MAW) spots of Io and Europa as observed by the Near‐Infrared Spectrograph onboard the James Webb Space Telescope. These auroral footprint features have been measured previously, but only in emission. Here, the derived ionospheric H3+ ${\mathrm{H}}_{3}^{+}$ emission, temperature and column density are reported ...

Emerging Device Applications From Strong Light–Matter Interactions in 2D Materials
Two‐dimensional semiconductors enable extremely compact optoelectronic devices such as solar cells, sensors, LEDs, and lasers. Their strong light–matter interactions allow efficient light emission, detection, and energy conversion. This review article discusses the recent progress in integrating these materials with optical cavities and nanostructures ...

An Alternative Approach to Spontaneous Photon Triplets Generation
Day by day, communication and computing technologies are progressing at a lightning speed, which is particularly true of the quantum version of these technologies (QIST). Increasingly, these technologies are emerging from unusual and sometimes bewildering quantum optical effects, which are based on exotic quantum physical theories.

Falsifying cosmological models based on a non-linear electrodynamics
Recently, the nonlinear electrodynamics (NED) has been gaining attention to generate primordial magnetic fields in the Universe and also to resolve singularity problems. Moreover, recent works have shown the crucial role of the NED on the inflation. This

Toward a Dynamic Model for Topside Ionospheric Irregularities: Spherical Harmonic Decomposition
Abstract Ionospheric irregularities arise from highly dynamic and turbulent processes related to magnetosphere‐ionosphere coupling and can lead to electromagnetic signal distortion or loss of lock events in global navigation satellite system signals, representing a hazard associated with space weather events. For this reason, understanding and modeling
