Abstract. Recently Kordas (1995 Class. Quantum Grav. 12 2037) and Meinel and Neugebauer (1995 Class. Quantum Grav. 12 2045) studied the conditions for reflection symmetry in stationary axisymmetric space–times in vacuum. They found that a solution to the Einstein field equations is reflectionally symmetric if their Ernst’s potential E(ρ = 0, z) = e(z) on a portion of the positive zaxis extendin...
2014 Network equations for finite and extended superconducting arrays are studied in the presence of external currents. Critical currents are obtained for typical network geometries. In the presence of a magnetic field, the critical currents are shown to be very sensitive to the underlying topology of the network. This is illustrated through explicit calculations on an extended square network. ...
Selon les projections de l’Insee publiées en 2021, la France comptera entre 58 et 79 millions d’habitants 2070. Le scénario central conduit à une population 68 d’habitants. Il annonce plus vieille qu’aujourd’hui, légère diminution partir 2044 alors que précédentes tablaient sur un maintien croissance. L’excédent des décès naissances ne serait effet compensé par solde migratoire positif. L’écart...
FUTURE PROJECTION OF HEAT STROKE AND SLEEP DISTURBANCE FOR 2070'S AUGUST IN TOKYO, NAGOYA, AND OSAKA
Chelonians are expected to be negatively impacted by climate change due to limited vagility and temperature-dependent sex determination. However, few studies have examined how freshwater turtle distributions may shift under different climate change scenarios. We used a maximum entropy approach to model the distribution of five widespread North American Kinosternon species (K. baurii, K. flavesc...
Climate change makes the climate system of a given region unpredictable and increases risk water-related problems. GCMs (global models) help in understanding future conditions over region. In this study, 12 from CMIP6 (coupled model intercomparison project six) were evaluated ranked based on their abilities to describe historical observed series. The ensemble mean bias-adjusted best five models...
Off-time pubertal maturation is associated with mental disorders, presumably due to stress caused by deviation from peers that could also attract negative attention and result in being bullied. Stress related to off-time maturation could be acted out by involving oneself in bullying behavior. The associations between pubertal timing and involvement in bullying have so far not been a focus of re...
This study, using species distribution modeling (involving a new approach that allows for uncertainty), predicts the distribution of climatically suitable areas prevailing during the mid-Holocene, the Last Glacial Maximum (LGM), and at present, and estimates the potential formation of new habitats in 2070 of the endangered and rare Tertiary relict tree Davidia involucrata Baill. The results reg...
This memo provides a mechanism whereby messages conforming to the MIME specifications [RFC 2045, RFC 2046, RFC 2047, RFC 2048, RFC 2049] can convey presentational information. It specifies the "Content-Disposition" header field, which is optional and valid for any MIME entity ("message" or "body part"). Two values for this header field are described in this memo; one for the ordinary linear pre...
