Abstract Vertical root fractures are more commonly encountered following endodontic treatment and in teeth without treatment, with habits like bruxism eating coarse, hard food. The most predisposed to fracture the premolars of maxilla mandible, mesial roots mesiobuccal mandibular molars, maxillary molars incisors. Timely identification cracked is key since it permits a conservative preventive a...

We report a detailed analysis of the coronal abundance of 4 stars with varying levels of activity and with accurately known photospheric abundances. The coronal abundance is determined here using a line flux analysis and a full determination of the differential emission measure. Photospheric abundance values are taken from the literature. Previous coronal abundance determinations have generally...

     Urethralduplication is a rare condition occurs as a congenital malformation either independently or in the setting of other congenital malformations such as caudal duplication syndrome. Its prevalence becomes even rarer if it manifests as two side-by-side tracts in coronal plan.Nonetheless, we introduce a unique presentation of complete coronal urethral duplication accompanied by astoundin...

Coronal mass ejections (CMEs) are huge expulsions of magnetized matter from the Sun and stars, traversing space with speeds millions kilometers per hour. Solar CMEs can cause severe weather disturbances consumer power outages on Earth, whereas stellar may even pose a hazard to habitability exoplanets. While ejected by our be directly imaged white-light coronagraphs, for stars this is not possib...

We revisit the flare on 1992 January 13, which is now universally termed the “Masuda flare”. Our work is motivated by the remarkable improvement of Yohkoh hard X-ray imaging, which was only achieved after the intensive investigations on this famous event. With the calibrated Hard X-ray Telescope (HXT) data, we find that the hard X-ray coronal source is indeed a loop-top source, located slightly...

BACKGROUND The most-widely used visual rating scale (VRS) for medial temporal atrophy is the T1-weighted (T1W) coronal VRS developed by Scheltens et al. However, it is often difficult to use the T1W-coronal VRS in cases with limitations in obtaining T1W-coronal images. To overcome this issue, we modified the T1W-coronal VRS onto the axial plane. OBJECTIVE The purposes of this study were to va...
