...they stated that "thus far, a similar formation has not been described elsewhere in the temporal bone." ...they posited that amniotic fluid contamination of the middle ear 3, squamous metaplasia ...4, or the presence of epidermoid formations in other areas of the temporal bone may explain the genesis of congenital cholesteatoma 1.
To study the protective effect of "Huang Lian Jie Du Tang" active fraction (HLJDTAF) on experimental cerebral ischemia.
Middle cerebral artery occlusion (MCAO) in rats was used to observe the ...protective effect of HLJDTAF on ischemia stroke. Common carotid artery occlusion (CCAO) rat was used to analyse the effect of HLJDTAF on blood brain barrier (BBB) permeability. Common carotid artery occlusion and reperfusion repeatedly (CCAORR) in mice were used to test effect of HLJDTAF on gasp time, brain exponential and water content of brain.
HLJDTAF could improve the abnormal behavior of MCAO rats and decrease the infarction area (P < 0. 05, P < 0. 01). HLJDTAF could also significantly prolong the shorten gasp time of CCAORR mice, reduce the brain exponential and decrease the water content in brain (P < 0. 05, P < 0. 01).
HLJDTAF can protect the brain ischemia injury.
We report first results from the CHinese Exoplanet Searching Program from Antarctica (CHESPA)---a wide-field high-resolution photometric survey for transiting exoplanets carried out using telescopes ...of the AST3 (Antarctic Survey Telescopes times 3) project. There are now three telescopes (AST3-I, AST3-II, and CSTAR-II) operating at Dome A---the highest point on the Antarctic Plateau---in a fully automatic and remote mode to exploit the superb observing conditions of the site, and its long and uninterrupted polar nights. The search for transiting exoplanets is one of the key projects for AST3. During the Austral winters of 2016 and 2017 we used the AST3-II telescope to survey a set of target fields near the southern ecliptic pole, falling within the continuous viewing zone of the TESS mission \citep{Ricker10}. The first data release of the 2016 data, including images, catalogs and lightcurves of 26578 bright stars (\(7.5\le i \le15\)) was presented in \citet{Zhang18}. The best precision, as measured by the RMS of the lightcurves at the optimum magnitude of the survey (\(i=10\)), is around 2\,mmag. We detect 222 objects with plausible transit signals from these data, 116 of which are plausible transiting exoplanet candidates according to their stellar properties as given by the TESS Input Catalog \citep{Stassun17}, Gaia DR2 \citep{Gaia18} and TESS-HERMES spectroscopy \citep{Sharma18}. With the first data release from TESS expected in late 2018, this candidate list will be a timely for improving the rejection of potential false positives.
Located at Dome A, the highest point of the Antarctic plateau, the Chinese Kunlun station is considered to be one of the best ground-based photometric sites because of its extremely cold, dry, and ...stable atmosphere(Saunders et al. 2009). A target can be monitored from there for over 40 days without diurnal interruption during a polar winter. This makes Kunlun station a perfect site to search for short-period transiting exoplanets. Since 2008, an observatory has been built at Kunlun station and three telescopes are working there. Using these telescopes, the AST3 project has been carried out over the last six years with a search for transiting exoplanets as one of its key programs (CHESPA). In the austral winters of 2016 and 2017, a set of target fields in the Southern CVZ of TESS (Ricker et al. 2009) were monitored by the AST3-II telescope. In this paper, we introduce the CHESPA and present the first data release containing photometry of 26,578 bright stars (m_i < 15). The best photometric precision at the optimum magnitude for the survey is around 2 mmag. To demonstrate the data quality, we also present a catalog of 221 variables with a brightness variation greater than 5 mmag from the 2016 data. Among these variables, 179 are newly identified periodic variables not listed in the AAVSO databasea), and 67 are listed in the Candidate Target List(Stassun et al. 2017). These variables will require careful attention to avoid false-positive signals when searching for transiting exoplanets. Dozens of new transiting exoplanet candidates will be also released in a subsequent paper(Zhang et al. 2018b).
The problem of orbit determination using one or two GPS satellites is discussed. Methods of getting initial values based on linear translation is presented; the Secant method and the descend Newton ...iterative procedure and the continuation algorithm are used synthetically to solve the nonlinear equations. Computer simulation shows that this algorithm can give preliminary state of satellite orbit with a certain precision in short time.
The construction of 1000 kV EHV AC\DC net challenges the reliability of relay protection unprecedentedly. One of these new issues is how to record the true value measured and sent by intelligent ...relay protection system. The introduction of switch in net-sample-net-trip substation causes uncertain transfer delay and arrival interval deviation, which makes the recorded data unreliable. While the mirrored GOOSE and SV packets from different network interfaces can not be sent at exactly the same time in direct-sample-direct-trip substation. To tackle this problem, a brand new packets gathering technique based on spectroscope is introduced. Based on the result of dynamic simulations carried out in CEPRI, different modes of digital fault recorder are compared and analyzed.
