Gadgets that can be used as a supporting medium children to learn more commonly used as a medium of entertainment, such as games. In the current era, it is not rare to find that people are not too interested in reading the Bible. Not only in the adult population, but also in teenagers and children. Children tend to only know one or two salient life stories of Bible characters. As to the character of David, the children tend to recognize David as someone who beat Goliath the Philistine commander. But other than that, most children do not know the story of David\u27s life more.This application is an interactive media that can be used by children to be able to recognize the biblical figures like David and Joseph. At each stage of the application that requires a reference to the Bible, has been provided so that children can directly read the reference and can also play this application. Overall this application helps children get to know the Bible figure better. The application used to create interactive media are Android Studio and supported by AndEngine

    Game is a multi media application that need some main parts such as, goal, challenge and game play or usually has been know as rules in a game.Survival action game will apply real time system in its game play. Real time game usually needs fast decision making method for artificial intelligence, so it can\u27t interrupt any system in the game.Backpropagation is one of the fastest method that can be used to process data for decision making. Backpropagation method can use data training transformation feature so outputs from backpropagate calculation can be different than before. In its application, backpropagation needs to applying winner-take-all architecture so backpropagation system, can run the training process nicely.Based on testing result, backpropagation system can be applied in real time game and data training addition feature can gives the transformation for making decision that can be different than before

    TESS Discovery of an ultra-short-period planet around the nearby M dwarf LHS 3844

    Full text link
    Data from the newly-commissioned \textit{Transiting Exoplanet Survey Satellite} (TESS) has revealed a "hot Earth" around LHS 3844, an M dwarf located 15 pc away. The planet has a radius of 1.32±0.021.32\pm 0.02 R⊕R_\oplus and orbits the star every 11 hours. Although the existence of an atmosphere around such a strongly irradiated planet is questionable, the star is bright enough (I=11.9I=11.9, K=9.1K=9.1) for this possibility to be investigated with transit and occultation spectroscopy. The star's brightness and the planet's short period will also facilitate the measurement of the planet's mass through Doppler spectroscopy.Comment: 10 pages, 4 figures. Submitted to ApJ Letters. This letter makes use of the TESS Alert data, which is currently in a beta test phase, using data from the pipelines at the TESS Science Office and at the TESS Science Processing Operations Cente

    TOI 540 b: A Planet Smaller than Earth Orbiting a Nearby Rapidly Rotating Low-mass Star

    We present the discovery of TOI 540 b, a hot planet slightly smaller than Earth orbiting the low-mass star 2MASS J05051443-4756154. The planet has an orbital period of P=1.239149P = 1.239149 days (±\pm 170 ms) and a radius of r=0.903±0.052REarthr = 0.903 \pm 0.052 R_{\rm Earth}, and is likely terrestrial based on the observed mass-radius distribution of small exoplanets at similar insolations. The star is 14.008 pc away and we estimate its mass and radius to be M=0.159±0.014MSunM = 0.159 \pm 0.014 M_{\rm Sun} and R=0.1895±0.0079RSunR = 0.1895 \pm 0.0079 R_{\rm Sun}, respectively. The star is distinctive in its very short rotational period of Prot=17.4264+/−0.0094P_{\rm rot} = 17.4264 +/- 0.0094 hours and correspondingly small Rossby number of 0.007 as well as its high X-ray-to-bolometric luminosity ratio of LX/Lbol=0.0028L_X / L_{\rm bol} = 0.0028 based on a serendipitous XMM-Newton detection during a slew operation. This is consistent with the X-ray emission being observed at a maximum value of LX/Lbol≃10−3L_X / L_{\rm bol} \simeq 10^{-3} as predicted for the most rapidly rotating M dwarfs. TOI 540 b may be an alluring target to study atmospheric erosion due to the strong stellar X-ray emission. It is also among the most accessible targets for transmission and emission spectroscopy and eclipse photometry with JWST, and may permit Doppler tomography with high-resolution spectroscopy during transit. This discovery is based on precise photometric data from TESS and ground-based follow-up observations by the MEarth team.Comment: 18 pages, 7 figures.

    Background Ultrasound (US) has largely replaced contrast venography as the definitive diagnostic test for deep vein thrombosis (DVT). We aimed to derive a definitive estimate of the diagnostic accuracy of US for clinically suspected DVT and identify study-level factors that might predict accuracy. Methods We undertook a systematic review, meta-analysis and meta-regression of diagnostic cohort studies that compared US to contrast venography in patients with suspected DVT. We searched Medline, EMBASE, CINAHL, Web of Science, Cochrane Database of Systematic Reviews, Cochrane Controlled Trials Register, Database of Reviews of Effectiveness, the ACP Journal Club, and citation lists (1966 to April 2004). Random effects meta-analysis was used to derive pooled estimates of sensitivity and specificity. Random effects meta-regression was used to identify study-level covariates that predicted diagnostic performance. Results We identified 100 cohorts comparing US to venography in patients with suspected DVT. Overall sensitivity for proximal DVT (95% confidence interval) was 94.2% (93.2 to 95.0), for distal DVT was 63.5% (59.8 to 67.0), and specificity was 93.8% (93.1 to 94.4). Duplex US had pooled sensitivity of 96.5% (95.1 to 97.6) for proximal DVT, 71.2% (64.6 to 77.2) for distal DVT and specificity of 94.0% (92.8 to 95.1). Triplex US had pooled sensitivity of 96.4% (94.4 to 97.1%) for proximal DVT, 75.2% (67.7 to 81.6) for distal DVT and specificity of 94.3% (92.5 to 95.8). Compression US alone had pooled sensitivity of 93.8 % (92.0 to 95.3%) for proximal DVT, 56.8% (49.0 to 66.4) for distal DVT and specificity of 97.8% (97.0 to 98.4). Sensitivity was higher in more recently published studies and in cohorts with higher prevalence of DVT and more proximal DVT, and was lower in cohorts that reported interpretation by a radiologist. Specificity was higher in cohorts that excluded patients with previous DVT. No studies were identified that compared repeat US to venography in all patients. Repeat US appears to have a positive yield of 1.3%, with 89% of these being confirmed by venography. Conclusion Combined colour-doppler US techniques have optimal sensitivity, while compression US has optimal specificity for DVT. However, all estimates are subject to substantial unexplained heterogeneity. The role of repeat scanning is very uncertain and based upon limited data
