On the Age Distribution of Classical Cepheids in the Galaxy
Astronomische Nachrichten, Volume 346, Issue 5, June 2025.ABSTRACT We revisit the problem of the positive correlation between age and Galactocentric distance seen in Galactic Classical Cepheids, which at first sight may seem counter‐intuitive in the context of inside‐out galaxy formation. To explain it, we use the Besançon Galaxy Model and a simulation of star particles in the Galactic disc coupled with ...

JOR SPINE, Volume 8, Issue 2, June 2025.ABSTRACT Background Intervertebral disc (IVD) degeneration (IDD) is the main contributor to chronic low back pain (LBP), the leading cause of disability worldwide, with a significant impact on the quality of life and health of common people. The etiology of IDD is still unclear, but it has been largely demonstrated the crucial role of inflammation and ...

ChemistrySelect, Volume 10, Issue 21, June 4, 2025.In‐silico drug discovery pipeline for Mycetoma caused by Nocardia brasiliensis. A library of 1034 phytocompounds was screened to identify potent inhibitors, with Parviflorone F showing strong binding and stability against the 50S ribosomal unit. Molecular dynamics confirmed its inhibitory potential, offering a promising therapeutic candidate.

THE OPACITY OF SPIRAL GALAXY DISKS [PDF]
, 2007 The opacity of foreground spiral disks can be probed from the number of distant galaxies seen through them. To calibrate this number for effects other than the dust extinction, Gonzalez et al. (1998) developed the "Synthetic Field Method". A synthetic field is an extincted Hubble Deep Field added to the science field.

Formation of Spiral Galaxies [PDF]
International Astronomical Union Colloquium, 1977 Conventionally, two major components of spiral galaxies are distinguished: (1) a “spheroidal component”, which includes the central bulge and the surrounding halo, and (2) a “disc component”, which is basically flat and circular but is often warped at the edges. Other structures, such as bars or rings, may also be present, but they are probably of less
