Introduction: Studies of object perception are hampered by the difficulty of mathematically describing the similarity of realistic images. Recently, color based metrics have been developed to search for similar images in large databases of realistic images. Such metrics have been shown to predict human subjects’ similarity rankings of realistic images, because the color of realistic images ofte...

BACKGROUND Tissue engineering represents very exciting advances in regenerative medicine; however, periodontal literature only contains few reports. Emdogain (EMD) consists of functional molecules that have shown many advantages in regenerative treatments. This study investigated EMD effect on gingival fibroblast adhesion to different membranes. MATERIALS AND METHODS Two dense polytetrafluoro...

AIMS This three-arm study compared the clinical and radiographic efficacy of the modified minimally invasive surgical technique (M-MIST) alone and combined with enamel matrix derivative (EMD) or EMD plus bone mineral derived xenograph (BMDX), in the treatment of isolated, inter-dental intra-bony defects. MATERIALS AND METHODS Forty-five deep isolated intra-bony defects in 45 patients were inc...

BACKGROUND There are still limited data on the outcomes of regenerative periodontal surgery using a combination of an enamel matrix protein derivative (EMD) and autogenous bone (AB). AIM To evaluate the healing of deep intrabony defects treated with either a combination EMD+AB or EMD alone. MATERIALS AND METHODS Forty patients with advanced chronic periodontitis, with one deep intrabony def...

OBJECTIVES The purpose of this study was to compare the microbial and clinical effects of mechanical debridement (MD) alone or in combination with the application of enamel matrix derivative (EMD) and sustained-release micro-spherical minocycline (MSM) for treatment of peri-implant mucosal infl ammation (PIMI). MATERIALS AND METHODS Subjects with at least one implant with PIMI were included a...

Stochastic resonance (SR) has been widely used for extracting single-frequency weak periodic signals. For multi-frequency signals, empirical mode decomposition (EMD) can adaptively decompose the complex signal, but this method also suffers from mixing, which affects accuracy of detection. SR convert part noise energy into signal energy, compensates defects EMD. According to advantages and EMD, ...

OBJECTIVE To determine the acceptability of an emergency medical dispatch (EMD) system to people who call 999 to request an ambulance. METHODS Postal questionnaires to two systematic random samples of approximately 500 named callers to one ambulance service before, and one year after, the introduction of EMD. RESULTS The response rate was 72% (355 of 493) before, and 63% (297 of 466) after,...

The aim of this paper was to compare empirical mode decomposition (EMD) and two new extended methods of EMD named complex empirical mode decomposition (complex-EMD) and bivariate empirical mode decomposition (bivariate-EMD). All methods were used to analyze stabilogram center of pressure (COP) time series. The two new methods are suitable to be applied to complex time series to extract complex ...

In this paper, we study the security of the Encrypt-MaskDecrypt mode of operation, also called EMD, which was recently proposed for applications such as disk-sector encryption. The EMD mode transforms an ordinary block cipher operating on n–bit blocks into a tweakable block cipher operating on large blocks of size nm bits. We first show that EMD is not a secure tweakable block cipher and then d...
