Optical control of a metastable phase in the charge-density-wave Mott insulator ▫▫ investigated using time-resolved ARPES Beamtime NEP ID_545
No full textLight-induced metastable phases are exotic, long-lived out-of-equilibrium states of matter. Optical control offers a powerful approach to engineering these phases, enabling dynamic tuning of their electronic and structural properties. Using time- and angle-resolved photoemission spectroscopy, we investigate the emergence of a metastable phase induced by a strong infrared pump in the charge-density-wave (CDW)-Mott insulator 1T-TaS2. Furthermore, we demonstrate how its properties can be optically manipulated by varying the photoexcitation strength. A long-lived stabilization of the renormalized electronic band structure serves as a signature of the metastable phase. It displays a relaxed periodic lattice distortion (PLD) and primarily lattice-driven dynamics. The emergence of a new dispersive band in the vicinity of the Hubbard bands reveals the formation of a novel band structure unique to the metastable phase. Our pump-fluence-dependent studies reveal a threshold (incident) fluence ▫▫ ~ 1.3 mJ/▫▫ for inducing the metastable phase, above which the band renormalization continuously evolves with increasing fluence. For ▫▫ 3.4 mJ/▫▫, stronger photoexcitation progressively drives the phase to higher energies, accompanied by a more relaxed PLD and reduced CDW amplitude. The properties of the metastable phase are strongly influenced by the transient dynamics at each fluence, and the associated fast timescales suggest that the intrinsic CDW amplitude mode remains unaffected by optical manipulation. These findings highlight the potential of optical control in tuning the properties of metastable phases in quantum materials, offering new insights into the manipulation of CDW systems and paving the way for future investigations in non-equilibrium phase engineering
Ubiquitination dynamics in human tumour viruses
No full textThe ubiquitin conjugation system is a critical regulator of cellular homeo-stasis and influences various cellular processes. Viruses, as obligate intracel-lular parasites, have evolved sophisticated strategies to utilise this systemto enhance their survival, to either increase virus production or ensure thelong-term survival of the latently infected host. Viruses from almost allfamilies, including RNA and DNA viruses, are challenged byubiquitin-mediated mechanisms at different stages of their life cycle andhave evolved to exploit or bypass the host cell ubiquitination system fortheir own replication. In this review, we examine the diverse functions ofthe ubiquitin conjugation system during the different stages of viral infec-tion, including viral entry, replication, gene expression, assembly andrelease. We discuss how human oncogenic viruses manipulate host ubiquiti-nation pathways to maintain infection, evade immune responses and driveoncogenesis. Finally, we highlight new research aimed at uncovering theprecise molecular interactions between oncoviruses and the host ubiquitina-tion system, which will pave the way for the development of advancedtherapeutic strategies to treat viral infections and cancer

Comparative study of black carbon and other carbonaceous aerosols in four South-Eastern European hotspots
No full textAir pollution poses a substantial health risk, particularly in South-Eastern Europe (SEE) countries outside the purview of European Union (EU) regulations. Air quality in these regions is among the worst globally (Daul Čolović, 2019). In SEE, particularly during the winter season, carbonaceous aerosols (CA) constitute the dominant component of fine particulate matter (PM2.5) (Džepina, 2022). These aerosols predominantly originate from vehicular emissions, residential heating, coal-fired power plants, or other industrial
processes. The oxidative potential of PM, a simple measure of its detrimental health-effects, is largely associated with anthropogenic sources across Europe. Specifically, residential biomass burning and nonexhaust emissions from vehicles are the primary contributors. Black carbon (BC) and other fractions of CA, analysed in this study, serve as effective tracers for these sources

Sheffer stroke BCK-algebras via linear diophantine fuzzy structures
No full textThis study investigates linear Diophantine fuzzy structures within the framework of Sheffer stroke BCK-algebras (SBCK-algebras). We introduce and characterize linear Diophantine fuzzy SBCK-subalgebras and linear Diophantine fuzzy SBCK-ideals, establishing fundamental connections between these fuzzy structures and their corresponding crisp subalgebras and ideals. In particular, we prove that the level sets of linear Diophantine fuzzy SBCK-subalgebras form SBCK-subalgebras, and, conversely, every SBCK-subalgebra gives rise to such a fuzzy structure. Additionally, we show that every linear Diophantine fuzzy SBCK-ideal induces a linear Diophantine fuzzy SBCK-subalgebrahowever, the converse does not necessarily hold. Several structural properties, homomorphic images, and intersections of such fuzzy ideals are also examined. These results demonstrate how linear Diophantine logic naturally integrates with Sheffer stroke BCK-algebras and enriches their algebraic behavior
