The time elapsed between successful cell infection and the start of virus production is called the eclipse phase. Its duration is specific to each virus strain and, along with an effective virus production rate, plays a key role in infection kinetics. How the eclipse phase varies amongst cells infected with the same virus strain and therefore how best to mathematically represent its duration is...

KH 15D is a strongly variable T Tauri star in the young star cluster NGC 2264 that shows a decrease in flux of 3.5 mag lasting for 18 days and repeating every 48 days. The eclipsing material is likely due to orbiting dust or rocky bodies in a partial ring or warped disk that periodically occults the star. We measured the polarized spectrum in and out of eclipse at the Keck and Palomar observato...

Time-resolved, multi-epoch, Hubble Space Telescope ultraviolet eclipse spectrophotometry is presented for the magnetic cataclysmic variables (mCVs) V1309 Ori, MN Hya, V2301 Oph, and V1432 Aql. Separation of the eclipse light curves into specific wavebands allows the multiple emission components to be distinguished. Accretion-heated photospheric spots are detected in V1309 Ori and V2301 Oph, ind...

Eclipse is a popular open-source software development workbench, and is suitable for the integration of experimental research tools. It includes a state-of-the-art plug-in technology, and so it can be considered as a platform for reusable components, or composition environment. We evaluate the Eclipse platform from this point of view, and discuss strengths and weaknesses of its plug-in

Eclipse is a heterogeneous multiprocessor architecture for high-performance media processing, including high-definition MPEG encoding/decoding. The scalable architecture framework concurrently executes media processing kernels in function-specific multi-tasking coprocessors and a media processor, communicating via on-chip memory. Eclipse instances combine application configuration flexibility w...

Abstract We report on an unusually bright observation of PSR J1720−0533 using the Five-hundred-meter Aperture Spherical radio Telescope (FAST). The pulsar is in a black widow system that was discovered by Commensal Radio Astronomy FAST Survey (CRAFTS). By coincidence, scintillation maximum simultaneous with eclipse our observation, which allowed for precise measurements flux density variations,...

We use ASAS V-band and ASAS-SN g-band observations to model the long-period detached eclipsing binary ASASSN-21co. show an eclipse of depth V ~ 0.6 mag in April 2009. from March 2021 similar duration depth, suggesting orbital period 11.9 years. combine with additional BVRI photometry taken during using PHOEBE. find that system is best described by two M giants a ratio secondary radius primary ~...

As the study of ionospheric behavior during various solar activities is an important task, studies changes eclipse events have been widely performed in different regions globe. This paper investigates responses to on 22 July 2009 over Nepal using total electron content (TEC) measured by dual-frequency Global Positioning System (GPS) receivers. The time-averaged Vertical TEC (vTEC) ten GPS stati...

A total solar eclipse occurred at the ascending node of Moon's orbit on 2 July 2019, with an magnitude 1.0459. The totality was visible from southern Pacific Ocean east New Zealand to Coquimbo Region (Chile) and Central Argentina sunset, maximum 4 min 32 s Ocean. recent Great American Eclipse, 21 August 2017, clearly showed that ionosphere is strongly affected by totality. In order explore iono...
