Uncertainty principle from the noise of gravitons

European Physical Journal C: Particles and Fields
The effect of the noise induced by gravitons in the case of a freely falling particle from the viewpoint of an external observer has been recently calculated in Phys. Rev. D 107, 066024 (2023) .

“Young Get Older, But Old Get Younger”: Warming‐Induced Circulation Change Explains Contrasting Pattern of Projected Pacific Deoxygenation

AGU Advances, Volume 7, Issue 6, September 2026.
Abstract Future projections of oxygen and water mass age change in the upper Pacific Ocean show a consistent pattern: strong deoxygenation and increased age in the well‐ventilated subtropical gyres, contrasted by weak deoxygenation and younger age in the poorly ventilated tropical oxygen minimum zones.

Very high energy gamma ray astronomy and non pulsating low mass x-ray binaries [PDF]

, 1991
This thesis is concerned with non pulsating Low Mass X-Ray Binaries as Very High Energy γ-ray sources, in particular Scorpius X-1; the brightest of these objects in X-rays, and the most likely to be detectable at energies above 250 GeV.

Geophysical Investigation of a Thermal Field in Abu Dhabi, United Arab Emirates

Earth and Space Science, Volume 13, Issue 9, September 2026.
Abstract In the Abu Dhabi Emirate, near Madinat Zayed and Liwa, studies have identified high geothermal gradients and high‐heat‐flow areas. Assessing the geothermal potential in this region requires a detailed mapping of subsurface geological formations and their thermal properties.

Satellite‐Derived Volume Budget of Antarctic Sea Ice

Earth and Space Science, Volume 13, Issue 9, September 2026.
Abstract In recent years, the Antarctic has seen a notable shift in sea ice trends: Where sea ice extent and volume were increasing on average, they have shown an unprecedented decline since 2016. Understanding the drivers of this shift is crucial to determining the impacts of climate change on sea ice and improving modeling of Antarctic sea ice ...

An Operational Daily‐Filtered Dominion Radio Astrophysical Observatory F10.7 cm Solar Radio Flux Product

Earth and Space Science, Volume 13, Issue 9, September 2026.
Abstract The F10.7 solar radio flux density, or F10.7, is a disk‐integrated measure of the Sun's total emission at 10.7 cm (2.8 GHz) and is a widely‐used proxy of solar activity. F10.7 emissions primarily originate from the Sun's upper chromosphere and lower corona. High‐frequency, transient “radio bursts” can dramatically increase the magnitude of F10.

High Resolution Field Observations of Shoreward Sediment Transport Within the Wave Bottom Boundary Layer on a Sandy Beach

Earth and Space Science, Volume 13, Issue 9, September 2026.
Abstract We introduce a data archive containing the first highly resolved profiles of velocity and sediment concentration within the wave bottom boundary layer (WBBL) on a natural sandy beach. Resolution of the thin WBBL was made possible by deployment of a unique “Multi‐Frequency Doppler” (MFDop) bistatic acoustic profiling instrument on an Oregon ...

Deformation Patterns and Rupture Mechanisms of the Longitudinal Valley Fault in Eastern Taiwan: Insights From Three‐Dimensional Discrete Element Modeling

Earth and Space Science, Volume 13, Issue 9, September 2026.
Abstract Active faults exhibit complex geometric features, with rupture processes controlled by the coupled effects of tectonic loading, fault geometry, and internal displacement heterogeneity. To elucidate the interrelationship between long‐term deformation, stress redistribution, and rupture evolution, we constructed a three‐dimensional numerical ...
