Comparing CT‐Like Images Based on Ultra‐Short Echo Time and Gradient Echo T1‐Weighted MRI Sequences for the Assessment of Vertebral Disorders Using Histology and True CT as the Reference Standard

Journal of Magnetic Resonance Imaging, Volume 59, Issue 5, Page 1542-1552, May 2024.
Background Several magnetic resonance (MR) techniques have been suggested for radiation‐free imaging of osseous structures. Purpose To compare the diagnostic value of ultra‐short echo time and gradient echo T1‐weighted MRI for the assessment of vertebral pathologies using histology and computed tomography (CT) as the reference standard.

Upper‐level wind mode over the North Atlantic‐Arctic Ocean leading to coherent variations of Eurasian and North American winter temperatures and weakness in the CMIP6 models

International Journal of Climatology, Volume 44, Issue 2, Page 428-447, February 2024.
The synchronization of winter temperature anomalies between northern Eurasia and North America is observed at an inter‐annual time scale. The V300‐EOF2 mode over the North Atlantic‐Arctic Oceans modulates the coherent circulation variation at both the troposphere and the stratosphere, affecting temperature anomalies over northern Eurasia and North ...

α‐d‐2′‐Deoxyadenosine, an irradiation product of canonical DNA and a component of anomeric nucleic acids: crystal structure, packing and Hirshfeld surface analysis

Acta Crystallographica Section C, Volume 80, Issue 2, Page 21-29, February 2024.
α‐d‐2′‐Deoxyadenosine, the anomer of the canonical nucleoside β‐d‐2′‐deoxyadenosine, is a γ‐irradiation product of DNA and a constituent of anomeric DNA. The single‐crystal X‐ray analysis reveals the formation of two conformers with unusual conformational parameters for α‐nucleosides.
