In vitro exposure to power frequency magnetic fields (MF) has been reported to influence cell proliferation and differentiation. However, the nature of the response of different human cancer cell types to these fields has not been sufficiently characterized. The present work investigates the response of two proliferating human cell lines of neuroblastoma (NB69) and hepatocarcinoma (HepG2) to a ...

OBJECTIVE To determine the clinicopathologic features and the disease course of patients with follicular mycosis fungoides (MF). DESIGN A multicenter, 14-year, retrospective cohort analysis. SETTING Dutch Cutaneous Lymphoma Group. PATIENTS Fifty-one patients with the clinicopathologic features of follicular MF with (n = 49) or without (n = 2) associated follicular mucinosis. Follow-up dat...

six fluorescent compounds were isolated and characterized in rhizomorph of a. mellea and were presented first as: f , f , f , mf , mf and mf . these compounds differed by rf on chromatoplaque, max in uv spectra and ex, em and max in fluorescence spectra. their gc-ms analysis indicated that f has a phenolic moiety and the other five are the benzenic derivatives. f compound was more fluorescent r...

Some epidemiological studies suggest that exposure to power frequency magnetic fields (MFs) may be associated with an elevated risk of human cancer, but the experimental database remains limited and controversial. We investigated the hypothesis that 60-Hz MF action at the cellular level produces changes in gene expression that can result in neoplastic transformation. Twenty-four hour 200 microT...

This paper presents the Metric-Frequency Calculator (MF Calculator), an online application to analyze similarity. The MF Calculator implements the MF similarity algorithm developed by Sales and Wakker (2009) for the quantitative assessment of similarity in ill-structured data sets. It is widely applicable as it can be used when there is little prior control of the variables to be observed, with...

In this paper, a low-complexity multiple feedback successive interference cancellation (MF-SIC) strategy is proposed for the uplink of multiuser multiple-input multiple-output (MU-MIMO) systems. In the proposed MF-SIC algorithm with shadow area constraints (SAC), an enhanced interference cancellation is achieved by introducing constellation points as the candidates to combat the error propagati...

Background: Mycosis Fungoides (MF) is the most common and indolent form of Cutaneuse T-cell Lymphomas (CTCL), that usually occurs in old adults. Objectives: To determine epidemiologic features and patients characteristics of MF in Isfahan (Iran). Methods: We performed a retrospective study in MF clinic of alzahra hospital that is the main center for treatment of MF patients in Isfahan (Iran) an...

The initiation of retinal development in Drosophila begins at the posterior center (PC) of the eye disc margin. The front of the differentiation wave, recognized as a morphogenetic furrow (MF), moves from posterior to anterior. What determines MF initiates from the specific PC site is still unclear. The unpaired (upd) gene is expressed at PC at early third instar, just before the time of MF ini...

A new method is presented for enhancing the contrast between speech and background noise. It is based on modulation-frequency (MF) analysis, inspired by the auditory system. Instead of selecting or weighting frequency channels as in previous MF-based methods, here the MF spectrum is processed directly. The dominant common MF (mostly corresponding to ) is enhanced by an adaptive bandpass filter ...

While several matrix factorization (MF) and tensor factorization (TF) models have been proposed for knowledge base (KB) inference, they have rarely been compared across various datasets. Is there a single model that performs well across datasets? If not, what characteristics of a dataset determine the performance of MF and TF models? Is there a joint TF+MF model that performs robustly on all da...
