| 1 | Improved scoring system for the electrocardiographic diagnosis of left ventricular hypertrophy显示文摘BACKGROUND Left ventricular hypertrophy(LVH) is a common manifestation of cardiovascular disease and a risk factor for cardiovascular morbidity and mortality, but available methods for its electrocardiographic(ECG) diagnosis have limited accuracy.AIM To investigate findings associated with LVH on ECG and developed an improved system for the diagnosis of LVH.METHODS A cohort study comparing ECG data acquired within 30 days of transthoracic echocardiography(TTE) was performed. Multivariate regression analysis identified ECG findings associated with increased LV mass and mass index. A scoring system was derived and performance compared to established criteria for LVH.RESULTS Data from 5486 outpatients with TTEs and corresponding ECGs were included in the derivation cohort, 333(6.1%) of whom had LVH by TTE. In the primary regression analysis, findings associated with LVH were amplitudes of Q in V3, R in V6, S in V3, T in V6, P' in V1, P in V6, as well as R and T-axis discordance, R peak time in V6, QRS duration, weight, height, sex, and age. From this we derived a score consisting of 5 criteria, and validated it in an independent cohort of 910 patients. With a threshold of 1.5 points, sensitivity and specificity were67.9% and 81.4%, and 62.5% and 83.2% in the derivation and validation cohorts,respectively. With a threshold of 2 points, sensitivity and specificity were 42.3% and 93.0%, and 37.5% and 93.4% in these cohorts.CONCLUSIONS This score had superior sensitivity for detection of LVH by ECG while making a modest sacrifice in specificity compared to conventional criteria. | Eric D Braunstein Lori B Croft Jonathan L Halperin Steve L Liao | 2019 | World Journal of Cardiology2019，11，3： | 2 |

| 3 | Opportunities to search for extraterrestrial intelligence with the FAST显示文摘The discovery of ubiquitous habitable extrasolar planets,combined with revolutionary advances in instrumentation and observational capabilities,has ushered in a renaissance in the search for extraterrestrial intelligence(SETI).Large scale SETI activities are now underway at numerous international facilities.The Five-hundred-meter Aperture Spherical radio Telescope(FAST)is the largest single-aperture radio telescope in the world,and is well positioned to conduct sensitive searches for radio emission indicative of exo-intelligence.SETI is one of the five key science goals specified in the original FAST project plan.A collaboration with the Breakthrough Listen Initiative was initiated in 2016 with a joint statement signed both by Dr.Jun Yan,the then director of National Astronomical Observatories,Chinese Academy of Sciences(NAOC),and Dr.Peter Worden,Chairman of the Breakthrough Prize Foundation.In this paper,we highlight some of the unique features of FAST that will allow for novel SETI observations.We identify and describe three different signal types indicative of a technological source,namely,narrow band,wide-band artificially dispersed and modulated signals.Here,we propose observations with FAST to achieve sensitivities never before explored.For nearby exoplanets,such as TESS targets,FAST will be sensitive to an EIRP of 1.9×1011 W,well within the reach of current human technology.For the Andromeda Galaxy,FAST will be able to detect any Kardashev type II or more advanced civilization there. | Di Li Vishal Gajjar Pei Wang Andrew Siemion Zhi-Song Zhang Hai-Yan Zhang You-Ling Yue Yan Zhu Cheng-Jin Jin Shi-Yu Li Sabrina Berger Bryan Brzycki Jeff Cobb Steve Croft Daniel Czech David DeBoer Julia DeMarines Jamie Drew J.Emilio Enriquez Nectaria Gizani Eric J.Korpela Howard Isaacson Matthew Lebofsky Brian Lacki David H.E.MacMahon Morgan Nanez Chen-Hui Niu Xin Pei Danny C.Price Dan Werthimer Pete Worden Yunfan Gerry Zhang Tong-Jie Zhang FAST Collaboration | 2020 | Research in Astronomy and Astrophysics2020，20，5： | 1 |
