Interregional differences undermine sperm trend conclusions.
Environmental Genome Project. Issues such as these should be carefully considered and addressed during the early stage of the project. As noted at the beginning of the Environmental Genome Project symposium , the project is evolving and is a work in progress. As with any evolving program, it will continue to be molded by new ideas, information, and technologies. The goal of the initial phase of...
متن کاملRegional differences invalidate U.S. sperm trend conclusions.
-Patients with melanoma who had one or more close relatives with melanoma were studied for their natural-killer-cell (NK) activity against cultured melanoma cells and Chang cells. A high proportion of the patients and their relatives were found to have low NK activity against these target cells. In most of the patients this could not be attributed to general depression of their immune function,...
متن کاملThe need to pay attention to differences in health literacy and knowledge in health education interventions
The Health Literacy (HL) is an individual and social capacity for access, understanding, evaluation of information and health services, and optimal utilization of it for health promotion [1]. Today, HL has been recognized as an important and vital indicator of the results and costs of health care the need for the effective health care system, has a good level of health literacy [2]. According t...
متن کاملPolynomial cancellation coding and finite differences
We give here a mathematical context for polynomial cancellation coding, proposed recently to reduce intercarrier interference in orthogonal frequency division multiplexing (OFDM). In particular, we analyze polynomial cancellation coding (PCC) in terms of finite differences.
متن کاملFace Recognition with Disparity Corrected Gabor Phase Differences
We analyze the relative relevance of Gabor amplitudes and phases for face recognition. We propose an algorithm to reliably estimate offset point disparities from phase differences and show that disparitycorrected Gabor phase differences are well suited for face recognition in difficult lighting conditions. The method reaches 74.8% recognition rate on the Lighting set of the CAS-PEAL database an...
