By analogy with Maxwellian electromagnetic field, the modified gravity for the rotating planet is presented. The theory reasons out the inclined orbit of rotating planet in the solar system, and explains the existence of orbit inclination angle of the planet. When the rotating planet revolves round the sun on the solar equatorial plane, the study yields results consistent with Newtonian gravity...

Superflares are large explosive events on stellar surfaces one to six orders-of-magnitude larger than the largest flares observed on the Sun throughout the space age. Due to the huge amount of energy released in these superflares, it has been speculated if the underlying mechanism is the same as for solar flares, which are caused by magnetic reconnection in the solar corona. Here, we analyse ob...

background and objectives: day-shift taxi drivers have a long duration of direct sun exposure. however, the efficiency of this occupational exposure in vitamin d synthesis has not been addressed yet. the aim of this study was to assess the vitamin d status of taxi drivers in tehran, and examine vitamin d status association with some anthropometric and circulating biomarkers. materials and metho...

Abstract Solar phase scintillation and solar amplitude are fundamentally important in deep space mission operations for designing a communication system capable of transmitting signals when the signal path is close to Sun. The ESA’s BepiColombo measurement data were analyzed previous paper terms power spectral density scintillation, also with comparison Woo’s theory, X-band Ka-band propagate Su...

the functions of shelters are basically the same everywhere: to avoid extreme weather and to provide shelter for a comfortable living and working environment; but the designs and processes for those in different climates are significantly different. to live in the tropical area, olgyay stated two major problems the habitants have to be prepared for: the avoidance of excessive solar radiation an...

High-cadence, multiwavelength optical observations of a solar active region (NOAA 10969), obtained with the Swedish Solar Telescope, are presented. Difference imaging of white light continuum data reveals a white light brightening, 2 min in duration, linked to a co-temporal and co-spatial C2.0 flare event. The flare kernel observed in the white light images has a diameter of 300 km, thus render...

We use high-resolution UV spectra taken by the Space Telescope Imaging Spectrograph instrument on board the Hubble Space Telescope to study the 5.5 pc line of sight to the K0 V star 36 Oph A. The one interstellar component detected for this line of sight has a velocity inconsistent with the local interstellar cloud (LIC) flow vector, but consistent with the flow vector of the so-called G cloud,...

A polarizing heliospheric imager is a critical next generation tool for space weather monitoring and prediction. Heliospheric imagers can track coronal mass ejections (CMEs) as they cross the solar system, using sunlight scattered by electrons in the CME. This tracking has been demonstrated to improve the forecasting of impact probability and arrival time for Earth-directed CMEs. Polarized imag...

In this paper, we introduce a Takagi-Sugeno (TS) fuzzy model which is derived from a typical Multi-Layer Perceptron Neural Network (MLP NN). At first, it is shown that the considered MLP NN can be interpreted as a variety of TS fuzzy model. It is discussed that the utilized Membership Function (MF) in such TS fuzzy model, despite its flexible structure, has some major restrictions. After modify...
