Abstract Two tropical cyclones (TCs) that make landfall close together can induce sequential hazards to coastal areas. Here we investigate the change in TC historical and future projected climates. We find chance of has been increasing over past several decades at many US locations. Under high (moderate) emission scenario, from two TCs impacting same location within 15 days may substantially in...

Heliospheric (HSP) radio emission detected by the Voyager spacecraft between 1.8 kHz and 3.6 kHz from the distant heliosphere is interpreted as emission generated close to and at the heliopause (HP), the interface between the ionised very local interstellar (LIC) gas and the supersonic solar wind (SW) stream. Radio emission is assumed to be triggered by secondary charge exchange ionisation of i...

Na radioactively decays to an excited state of Ne either by emission of a positron (90% probability) or by electron capture (10% probability). The excited Ne nucleus decays with a mean life 3×10−12 s to the ground state with the emission of a 1.274 MeV gamma. The positrons are emitted with a range of kinetic energies up to about 0.5 MeV. They lose this energy quickly (10−9 s) in the material !"...

This research studies the potential impact of climate change on future trend and changes of two well known drought indicators namely RDI and SPI in Yazd meteorological station, in central part of Iran. For this purpose, data of HadCM3 model that were resulted from GCM-runs based on the IPCC-SRES scenarios of A2 and B2 were acquired and analyzed for projection of daily Tmin, Tmax and precipitati...

In this paper, we analyze convergence rates of wavelet schemes for time-dependent convection-reaction equations within the framework of the Eulerian–Lagrangian localized adjoint method (ELLAM). Under certain minimal assumptions that guarantee H1-regularity of exact solutions, we show that a generic ELLAM scheme has a convergence rate O(h/ √ Δt +Δt) in L2-norm. Then, applying the theory of opera...

Achieving a peak aminoglycoside concentration (Cmax)/MIC of > or = 10 within 48 h of initiation of therapy for pneumonia caused by gram-negative organisms results in a 90% probability of therapeutic response by day 7. Targeting an MIC of 1 microgram/ml, empirical aminoglycoside loading doses of 348 (25th- to 75th-percentile range, 275 to 432) mg were calculated to obtain a Cmax/MIC of 10 in our...

A combined neural network and rule-based approach is suggested as a general framework for pattern recognition. This approach enables unsupervised and supervised learning, respectively, while providing probability estimates for the output classes. The probability maps are utilized for higher level analysis such as a feedback for smoothing over the output label maps and the identification of unkn...

Temperature extremes can cause disastrous impacts on ecological and social economic systems. China is very sensitive to climate change, as its warming rate exceeds that of the global mean level. This paper focused on the spatial and temporal changes of the temperature extremes characterized by the 95th percentile of maximum temperature (TX95), the 5th percentile of the minimum temperature (TN5)...

The chemical structures of AT2433-A1 (2), AT2433-A2 (3), AT2433-B1 (4) and AT2433-B2 (5) were elucidated by degradation and spectroscopic studies. Compounds 2-5 are disaccharides closely related to rebeccamycin. The aglycone in 2 and 3 was determined to be 6-N-methyl-11-chloro-5H-indolo[2,3-a]pyrolo[3,4-c]carbazole and in 4 and 5 it was determined to be 6-N-methyl-5H-indolo[2,3-a]pyrolo[3,4-c]c...
