A new method for digital image watermarking which does not require the original image for watermark detection is presented. Assuming that we are using a transform domain spread spectrum watermarking scheme, it is important to add the watermark in select coe cients with signi cant image energy in the transform domain in order to ensure non-erasability of the watermark. Previous methods, which di...

In order to search for economically and environmentally optimized fusion reactors, physics properties, engineering designs and the cost of electricity (COE) are evaluated by the PEC (Physics-Engineering-Cost) system code for several magnetic confinement fusion reactors including tokamak (TR), helical (HR) and spherical tokamak (ST) reactors. The life-cycle CO2 emission amounts are also evaluate...

Wavelet transform coe cients are de ned by both a magnitude and a sign. While promising algorithms exist for e ciently coding the transform coe cient magnitudes [7, 13, 9, 8, 11], current wavelet image coding algorithms are not e cient at coding the sign of the transform coe cients. It is generally assumed that there is no compression gain to be obtained from entropy coding of the sign. Only re...

BACKGROUND There is a growing mandate for Family Medicine residency programs to directly assess residents' clinical competence in Care of the Elderly (COE). The objectives of this paper are to describe the development and implementation of incremental core competencies for Postgraduate Year (PGY)-I Integrated Geriatrics Family Medicine, PGY-II Geriatrics Rotation Family Medicine, and PGY-III En...

This paper reports on the preliminary findings of an indepth case study of the implementation of a computerized order entry (COE) system at a medium-sized, acute care hospital. In this paper, we propose a theoreticallygrounded framework, based on work by Barley [8] [9], for analyzing organizational changes that may result from COE introduction and use the framework to analyze findings at the re...

Choroidal neovascularization (CNV) is a common pathology in age-related macular degeneration. In this study, we evaluated in a rat model the effect of an extract of Cinidium officinale Makino and its bioactive compound, butylidenephthalide, on laser-induced CNV. Experimental CNV was induced in Long-Evans rats by laser photocoagulation. C. officinale extract (COE) and butylidenephthalide was int...

Celastrus orbiculatus Thunb. has been used as a remedy against cancer and inflammatory diseases for thousands of years in China. Maspin is expressed in normal cells and downregulated in prostate tumor cells. The underlying mechanisms between C. orbiculatus extract (COE) and maspin remain unclear. In the present study, 3 target-specific 19-25 nucleotide maspin small interfering RNAs were designe...

The double porosity model allows to compute the pressure at a macroscopic scale in a fractured porous media, but requires the computation of some exchange coe cient characterizing the passage of the uid from and to the porous media (the matrix) and the fractures. This coe cient may be numerically computed by some Monte Carlo method, by evaluating the time a Brownian particle spend in the matrix...

Average interpolating wavelets are used to construct multilevel representations of large data sets. The data is partitioned into disjoint blocks, and each block is transformed separately. Properties of wavelet coe cients guarantees that this partitioning does not introduce arti cial boundary e ects. Coe cients are organized in a data structure that is well suited for real-time visualization wit...

We show how lattice paths and the re ection principle can be used to give easy proofs of unimodality results. In particular, we give a \one-line" combinatorial proof of the unimodality of the binomial coe cients. Other examples include products of binomial coe cients, polynomials related to the Legendre polynomials, and a result connected to a conjecture of Simion.
