Image simulation methods are applied to interpret mirror electron microscopy (MEM) images obtained from a movie of GaAs droplet epitaxy. Cylindrical symmetry of structures grown by droplet epitaxy is assumed in the simulations which reproduce the main features of the experimental MEM image contrast, demonstrating that droplet epitaxy can be studied in real-time. It is therefore confirmed that a...

The Maximum Eccentricity Method (MEM) is a standard tool for the analysis of planetary systems and their stability. method amounts to estimating maximal stretch orbits over sampled domains initial conditions. present paper leverages on MEM introduce sharp detector separatrices chaotic seas. After introducing analogue nearly-integrable action-angle Hamiltonians, i.e., diameters, we use low-dimen...

PURPOSE To determine which are the most sensitive tests, together with accommodative amplitude, to classify accommodative insufficiency (Al), we analyzed the relation between monocular estimated method (MEM) dynamic retinoscopy, monocular and binocular accommodative facility (MAF, BAF), and positive relative accommodation (PRA) with or without the presence of reduced amplitude of accommodation....

Morphologically and functionally distinct subpopulations of human memory B (B(Mem)) cells are identifiable by either their expression of CD27 or Fc receptor-like 4 (FCRL4), an immunoglobulin domain containing a receptor with strong inhibitory potential. We have conducted comparative transcriptome and proteome analyses of FCRL4(+) and FCRL4(-) B(Mem) cells and found that these two subsets have v...

Wavelet functions allow the sparse and efficient representation of a signal at different scales. Recently the application of wavelets to the denoising of maps of cosmic microwave background (CMB) fluctuations has been proposed. The maximum-entropy method (MEM) is also often used for enhancing astronomical images and has been applied to CMB data. In this paper, we give a systematic discussion of...

·To study the role of membranous phospholipids in calcification , liposomes made of phosphatidylserine and red blood cell ghosts (RBCG) prepared from rat and canine blood were incubated in minimal essential medium (MEM) with 2 .5 mM (mmol/l) calcium and 1.3 mM phosphate, pH 7.4 (MEM-2.5), and homologous (rat) or autologous (canine) plasma filtrate (serum) at 37 °C for up to 1 week. Calcificatio...

diseases of heart and stroke cause most deaths in both sexes of all ethnic groups. for more than 40 years epidemiological studies, experimental studies, and clinical trials have shown that numerous dietary risk factors affect serum lipids, atherogenesis and coronary heart disease (chd). substantial interest has recently focused on the hypothesis that the naturally occurring antioxidant vitamins...

The middle ear muscle (MEM) reflex is one of two major descending systems to the auditory periphery. There are two middle ear muscles (MEMs): the stapedius and the tensor tympani. In man, the stapedius contracts in response to intense low frequency acoustic stimuli, exerting forces perpendicular to the stapes superstructure, increasing middle ear impedance and attenuating the intensity of sound...

The aim of the present study was to evaluate the effect of Amburana cearensis extract during caprine ovarian tissue transportation on the survival of preantral follicles in vitro. HPLC was used to determine the fingerprint chromatogram of the ethanolic extract. Five goat ovarian pairs were divided into fragments. One fragment was fixed for histology and TUNEL analysis (fresh control). The other...

In 1990 Sakata and Sato applied the maximum entropy method (MEM) to a set of structure factors measured earlier by Saka and Kato with the Pendellosung method. They found the presence of non-nuclear attractors, i.e., maxima in the density between two bonded atoms. We applied the MEM to a limited set of Fourier data calculated from a known electron density distribution (EDD) of silicon. The EDD o...
