Sparse frequency agile linear modulation-orthogonal division multiplexing (LFM-OFDM) radar can improve anti-interference ability as well reduce the sampling rate of system. However, agility makes it difficult to realize coherent processing by using fast Fourier transform. To overcome this problem, a signal scheme for sparse LFM-OFDM is proposed obtain high range and Doppler resolution in study....

In seasonally dry environments, the amount of water held in living plant tissue—live fuel moisture (LFM)—is central to vegetation flammability. LFM-driven changes wildfire size and frequency are particularly important throughout southern California shrublands, which typically produce intense, rapidly spreading wildfires. However, relationship between spatiotemporal variation LFM resulting long-...

This communication proposes a gain design method of an α-β filter with linear frequencymodulated (LFM) waveforms to achieve optimal range prediction (tracking) of maneuvering targets in steady-state. First, a steady-state root-mean-square (RMS) prediction error, called an RMS-index, is analytically derived for a constant-acceleration target. Next, a design method of the optimal gains that minim...

Lateral Force Microscopy (LFM) studies were carried out on cleaved calcite sections in contact with solutions supersaturated with respect to otavite (CdCO3) or calcite-otavite solid solutions (SS) as a means to examine the potential for future application of LFM as a nanometer-scale mineral surface composition mapping technique. Layer-by-layer growth of surface films took place either by step a...

Foods high in fermentable oligosaccharides, disaccharides, monosaccharides, and polyols (FODMAPs) exacerbate symptoms of irritable bowel syndrome (IBS); however, their mechanism of action is unknown. We hypothesized that a high-FODMAP (HFM) diet increases visceral nociception by inducing dysbiosis and that the FODMAP-altered gut microbial community leads to intestinal pathology. We fed rats an ...

BACKGROUND The present study was undertaken to gain knowledge on the role of bile components and lecithin on development of aberrations in digestive functions which seemingly have increased in Atlantic salmon in parallel with the increased use of plant ingredients in fish feed. Post smolt Atlantic salmon were fed for 77 days one of three basal diets: a high fish meal diet (HFM), a low fishmeal ...

BACKGROUND Several studies on Caucasian volunteers have proven that milk is an effective recovery drink for athletes. Such benefit, however, cannot be directly applied to the lactose-intolerant Asian population. This study investigated the effects of ingesting water (WT), sports drink (SPD) and lactose-free milk (LFM) on cycling capacity. METHODS Ten healthy young men completed 3 randomized e...

An indoor TOA-based ranging system which uses an audible spread spectrum signal is presented. The indoor acoustic environment is modeled with a dense multipath propagation channel whose characteristics are very different from those of outdoor environments. The complexity and site-specific nature of indoor acoustic propagation, when using traditional correlation techniques, often lead to the cre...
