Peak to average power ratio (PAPR) is one of the main imperfections in the broadband communication systems with multiple carriers. In this paper, a new crest factor reduction (CFR) scheme based on interleaved phase sequence called Dummy Sequence Insertion Enhanced Partial Transmit Sequence (DSI-EPTS) is proposed which effectively reduces the PAPR while at the same time keeps the total complexit...

Y-C. Wu, A. L. Alexander Medical Physics, University of Wisconsin-Madison, Madison, WI, United States, Psychiatry, University of Wisconsin-Madison, Madison, WI, United States Background At higher levels of diffusion-weighting, the diffusion tensor model is inadequate for describing non-Gaussian diffusion that arises from complex tissue architecture (e.g., crossing white matter (WM) fiber groups...

The dynamic state index (DSI) is a scalar field that combines variational information on the total energy and enstrophy of flow with second law thermodynamics. Its magnitude combined local measure for non-stationarity, diabaticity, dissipation in flow, it has been shown to provide good qualitative indications onset presence precipitation organization storms. derived thus far ideal fluid models ...

Most of the grid projects are characterized by accessing huge volumes of data. For supporting this feature, different data services have arisen in the “grid” world. One of the most successful initiatives in that field is GridFTP, a high-performance transfer protocol, based on FTP but optimized for wide area networks. Although GridFTP provides reasonably good performance, GridFTP servers keep co...

introduction the dynamic state index (dsi) is being introduced on the basis of a newly developed theory termed the energy-vorticity theory (evt). as a weather index, the dsi can describe the temporal sequence and intensity of areas of high and low pressure; but as a climate index, it can also diagnose climate change based on the variation in solar radiation or the influences of friction. in phy...

4th Industrial Revolution technologies that blur the lines across physical, digital and biological domains have entered seed systems. The digitalisation of seeds' DNA is generating unstoppable growth big data on sequence information (DSI). paper analyses legal vacuum for DSI, which aggravates dematerialisation fragmentation seed, rendering it easier to control under legal, technological, social...

The Baltic Proper shows many signs of eutrophication. Nutrient changes over time have been discernable, and also within the Sea there are large spatial patterns. Present study analyses the spatial patterns of dissolved inorganic nitrogen and phosphorus as well as dissolved silicate (DSi) in the euphotic zone for the period 1990-2001. The focus is on the spatial heterogeneity with the aim to ide...

Reverse engineering binary code is notoriously difficult and, especially, understanding a binary’s dynamic data structures. Existing data structure analyzers are limited wrt. program comprehension: they do not detect complex structures such as skip lists, or lists running through nodes of different types such as in the Linux kernel’s cyclic doubly-linked list. They also do not reveal complex pa...

Electroencephalography (EEG) is typically viewed through the lens of spectral analysis. Recently, multiple lines of evidence have demonstrated that the underlying neuronal dynamics are characterized by scale-free avalanches. These results suggest that techniques from statistical physics may be used to analyze EEG signals. We utilized a publicly available database of fourteen subjects with wakin...

Many diffusion MRI researchers, including the Human Connectome Project (HCP), acquire data using multishell (e.g., WU-Minn consortium) and diffusion spectrum imaging (DSI) schemes (e.g., USC-Harvard consortium). However, these data sets are not readily accessible to high angular resolution diffusion imaging (HARDI) analysis methods that are popular in connectomics analysis. Here we introduce a ...
