For long duration, manned exploration to be cost-effective, it is necessary to automate routine manual operations. To enable such automated control, activity plans must coordinate the activities of the crew with other automated “agents” including robots, life support systems, and vehicle systems. An important challenge is assisting the crew in using automated planning software to construct and ...

The selection of high-yielding, short-duration rice cultivars is essential for the double-rice cropping system. High hill density could be achieved with less labor under machine transplanted conditions. Therefore, dense planting more practical machine-transplanted rice. While few studies have been conducted to certify feasibility cultivar combined in current study was executed determine effects...

The energy release in gamma-ray bursts is one of the most useful clues on the nature of their “inner engines”. We show that, within the framework of the relativistic external shocks afterglow model, the narrowness of the observed X-ray luminosity of GRB afterglows, implies that the energy of the GRB jets after the early afterglow phase spans less than one order of magnitude. This result is not ...

A 26-year-old woman, with no relevant personal or family history, experienced 3 resting syncopal episodes with tonic convulsions in a period of 2 months. The physical examination, electrocardiogram, echocardiogram, programmed stimulation, and a provocation test with flecainide were normal or negative. A subcutaneous Holter was implanted (Reveal® Plus Medtronic, Inc.) which was consulted a fortn...

We present nebular-phase observations and spectral models of Type Ic superluminous supernovae. LSQ14an and SN 2015bn both display late-time spectra similar to SN 2007bi, and the class shows strong similarity with broad-lined Type Ic SNe such as SN 1998bw. Near-infrared observations of SN 2015bn at +315d show a strong Ca II triplet, O I 9263, O I 1.13 μm and Mg I 1.50 μm, but no strong He, Si or...

Specific Objectives:  Derive, implement and evaluate rigorous and efficient Bayesian smoothing theory and schemes that respect nonlinear dynamics and capture non-Gaussian statistics, for robust persistent inference and learning, integrating information backward and forward in time over long durations in largedimensional multiscale fluid and ocean dynamics.  Derive and develop adaptive samplin...

In this paper we are concerned with the detection of quiet narrowband signals. More specifically, we assume that these signals are: 1) extremely weak, with a signal-to-noise ratio (SNR) of ¡20 dB or below on a per-sample basis, 2) moderately long, of the order of minutes or tens of minutes, and 3) narrowband but not tonal, with, for example, a bandwidth of a few tens of Hz at a sampling rate of...

We compare the luminosity function and rate inferred from the BATSE long bursts peak flux distribution with those inferred from the Swift peak flux distribution. We find that both the BATSE and the Swift peak fluxes can be fitted by the same luminosity function and the two samples are compatible with a population that follows the star formation rate. The estimated local long GRB rate (without b...

BACKGROUND Probability of survival from sudden cardiac arrest caused by ventricular fibrillation (VF) decreases rapidly with fibrillation duration. We hypothesized that cellular ischemia/fibrillation-induced electrophysiological deterioration underlies decreased survival. METHODS AND RESULTS We determined fibrillation monophasic action potential (MAP) morphology including action potential fre...
