Approximate reconstruction of inflationary potential with ACT observations
Physics Letters BThe Atacama Cosmology Telescope (ACT) has recently reported updated measurements of the scalar spectral index ns, revealing a tension with the predictions of many conventional inflationary models. In this work, we adopt a parameterization of the spectral

Weyl symmetry inspired inflation and dark matter
Physics Letters B, 2020 Motivated by the Weyl scaling gauge symmetry, we present a theoretical framework to explain cosmic inflation and dark matter simultaneously. This symmetry has been resurrected in recent attempts to formulate the gauge theory of gravity.

Improved Constraints on Andean Glaciations From the Lake Titicaca Continental Drilling Record
Paleoceanography and Paleoclimatology, Volume 41, Issue 6, June 2026.Abstract Long sedimentary records from tropical lakes provide crucial archives for reconstructing the timing and extent of tropical alpine glaciations, yet robust chronologies beyond the radiocarbon limit (ca. 50 ka) remain scarce. Here, we refine the ca. 350 kyr chronology for Lake Titicaca (Peru‐Bolivia) using radiocarbon dating, optically stimulated

Is the spectrum of gravitational waves the “Holy Grail” of inflation?
European Physical Journal C: Particles and Fields, 2019 It is often said that detecting a spectrum of primordial gravitational waves via observing B-mode polarization of the Cosmic Microwave Background is the “Holy Grail” of inflation.

BJOG: An International Journal of Obstetrics &Gynaecology, Volume 133, Issue 7, Page 1358-1372, June 2026.ABSTRACT Background Immersive virtual reality (VR) technology offers a non‐invasive, non‐pharmacological approach to reduce pain perception in patients undergoing diagnostic or interventional procedures. Objective To systematically evaluate the efficacy of immersive VR technology in reducing pain perception during obstetric and gynaecological ...

European Physical Journal C: Particles and FieldsIn this paper, we investigate the validity of the so-called cosmic no-hair conjecture in the framework of anisotropic inflation models of non-canonical scalar fields non-minimally coupled to a two-form field.

Inflation and nonsingular spacetimes of cosmic strings [PDF]
Physical Review D, 1998 Inflation of cosmic gauge and global strings is investigated by numerically solving the combined Einstein and field equations. Above some critical symmetry-breaking scales, the strings undergo inflation along the radial direction as well as the axial direction at the core.
