Signals of the QCD Phase Transition in the Heavens [PDF]
, 2007 The modern phase diagram of strongly interacting matter reveals a rich structure at high-densities due to phase transitions related to the chiral symmetry of quantum chromodynamics (QCD) and the phenomenon of color superconductivity.

Advanced Functional Materials, EarlyView.A novel oil–water selective conformance control agent, MPRP, is prepared via hydrophilic grafting and mechanical granulation. MPRP uniformly disperses in water, cohesively expands upon aging, and readily dissolves in the oil phase. During conformance control, it selectively aggregates in water channeling pathways to form effective plugs without ...

The Astrophysical JournalTheoretical investigations predict a minimum mass ratio of about 0.085–0.095 for contact binaries. If the mass ratio is below the critical value, a tidal instability occurs, forcing the stars to merge into a single object.

MASS TRANSFER IN ECLIPSING BINARY STARS
Odessa Astronomical Publications, 2017 Analysis of the properties of the eclipsing binary stars shows, that the stream-like mechanism of the mass transfer switches on at a contact evolutionary stage, preceding to a stage of binaries with a subgiant.

The light-curve intrinsic variability in 47 Kepler contact binary stars
Monthly Notices of the Royal Astronomical Society, 2022 ABSTRACT This work studies the significance of light-curve intrinsic variability in the numerical modelling of contact binaries. Using synthetic light curves, we show that the starspot-based intrinsic variability increases the apparent mass ratio by $\Delta q=5{{\ \rm per\ cent}}$.

Nanoscale Spatial Tuning of Superconductivity in Cuprate Thin Films via Direct Laser Writing
Advanced Functional Materials, EarlyView.Maskless direct laser writing enables local control of oxygen stoichiometry in epitaxial YBCO thin films under ambient conditions. Sub‐micrometer grayscale patterns with tunable optical response and superconducting transport properties are achieved.

Two Ultralow-mass-ratio Binary Systems at Critical Evolutionary Stages
The Astronomical JournalIn this paper, we present photometric observations and period analysis of two totally eclipsing binaries with extremely low-amplitude light curves. Both binaries exhibit typical W Ursae Majoris-type light curves with total eclipses, allowing for the ...

Microwave emission from southern contact-binary stars
The Astronomical Journal, 1993 We report the results of high-sensitivity 4.8 GHz observations of four southern contact-binary stars (AE Phe, YY Eri, RW Dor, and V757 Cen) made with the Australia Telescope Compact Array. None of these stars were detected above a 4σ level of 0.4 mJy.

Advanced Functional Materials, EarlyView.Low‐frequency noise spectroscopy defines the resolvable conductance states of synaptic FeFETs by coupling read‐current fluctuation with usable dynamic range. The resulting noise‐limited bit precision establishes a universal, device‐agnostic reliability metric beyond the memory window, enabling quantitative benchmarking and rational design of high ...
