Group Delay Dispersion Measurements on Mid‐Infrared Supermirrors

open access: yesAdvanced Optical Materials, EarlyView.
Group delay dispersion of novel semiconductor‐based optics is measured in the mid‐infrared spectral range (2.5 to 4.8 μm$\rm \umu{\rm m}$). Comparisons are made between simulations, measurements conducted with a home‐built white light interferometer, and measurements performed with a commercially available FTIR.

Beads of the Mokino Cemetery (3th – 6th Centuries Ad) in Perm Region

open access: yesПоволжская археология, 2019
The paper introduces into scientific discourse the beads from the Mokino burial ground and a series of accurately dated complexes (burials). The authors verify the modern concept of the site’s chronology.

Tailoring Optical and Vibrational Properties by Bond Confinement: The Case of Metavalent Chalcogenide and Pnictogen Thin Films

open access: yesAdvanced Optical Materials, EarlyView.
This perspective explores how intrinsic confinement effects in metavalent chalcogenide and pnictogen thin films alter optical and vibrational properties. By comparing thickness‐dependent effects across prototypical systems, this work highlights the role of unconventional bonding in shaping coherent phonon dynamics and dielectric functions, offering new

THE RELATIONSHIP BETWEEN SOLAR AND VOLCANIC ACTIVITY AND THE CHRONOLOGY OF ARCHAEOLOGICAL CULTURES OF EURASIA IN THE 4TH–1ST MILLENNIA BC

open access: yesJournal of Ancient History and Archaeology
A well-known problem of archaeological chronology is that radiocarbon chronology differs from historical chronology. Historical chronology of the Bronze Age corresponds to dendrochronology and radiocarbon chronology in case of using Bayesian statistics ...

The Kashi Artefacts in the Burials of the Zmeisky Catacomb Cemetery

open access: yesПоволжская археология, 2018
The paper aims to the chronology of burials within the chambers and in the undercats of the catacombs and pit interments of the Zmeisky catacomb burial ground in Republic of North Ossetia-Alania (excavations 2013–2014), based on the analysis of kashi ...

The boundary of the chronology violating set

open access: yes, 2016
A sufficiently general definition for the future and past boundaries of the chronology violating region is given. In comparison to previous studies, this work does not assume that the complement of the chronology violating set is globally hyperbolic. The

Exploring Functionally Enhanced BLP‐Trained Macrophage Subpopulations in S. Aureus Infection: Underlying Mechanisms and Therapeutic Significance

open access: yesAdvanced Science, EarlyView.
BLP‐trained macrophages show augmented resistance to infection, but their mechanisms remain unclear. scRNA‐seq identified 13 BMDM subsets, with two novel anti‐inflammatory/antibacterial subpopulations (C5/C7) emerging post‐BLP training. BLP training activates NRF2, attenuates oxidative stress/ferroptosis, and boosts glycolysis/OXPHOS. Adoptive transfer

Allosteric Modulation of Pathological Ataxin‐3 Aggregation: A Path to Spinocerebellar Ataxia Type‐3 Therapies

open access: yesAdvanced Science, EarlyView.
This study uncovers a new allosteric site in the Josephin domain of ataxin‐3 targeted by the molecular tweezer CLR01, which modulates protein aggregation, improves synaptic function in neuronal cells, and delays motor dysfunction in animal models.
