Seven cases of recurring digital fibroma were seen over a 35-year period. All demonstrated the classical clinical, macroscopic, and microscopic features of this distinct tumour, including the pathognomonic round, eosinophilic cytoplasmic inclusion bodies. Ultrastructurally, all seven cases were confirmed to be myofibroblastic in nature, and the morphology and intracellular topography of the inc...

Abstract. An information diagnostic system is currently being developed. The system is based on electromagnetic non-destructive testing and uses a matrix magnetic converter for revealing flaws and forecasting the reliability of machines and mechanisms. The considered algorithm, which analyses magnetic nondestructive testing results, uses a dynamic type matrix magnetic transducer. To estimate cr...

In this study, we show that the correct determination of surface morphology using scanning force microscopy (SFM) imaging and power spectral density (PSD) analysis of the surface roughness is an extremely demanding task that is easily affected by experimental parameters such as scan speed and feedback parameters. We present examples were the measured topography data is significantly influenced ...

Both the amplitude and latency of P300 vary with changes in stimulus parameters. Stimuli at intensities or pitch separations near threshold evoke a smaller and later P300. P300 is also affected by extraneous stimulus parameters in tasks where stimulus frequency separation is large and stimuli are well above intensity thresholds. For example, the presence of background white noise when tones are...

This study aims to predict vital soil physical properties, including clay, sand, and silt, which are essential for agricultural management environmental protection. Precision distribution of texture is crucial effective land resource precision agriculture. To achieve this, we propose an innovative approach that combines Geospatial Artificial Intelligence (GeoAI) with the fusion satellite imager...

The use of the data assimilation technique to identify optimal topography is discussed in frames of time-dependent motion governed by non-linear barotropic ocean model. Assimilation of artificially generated data allows to measure the influence of various error sources and to classify the impact of noise that is present in observational data and model parameters. The choice of assimilation wind...

In human 20S proteasomes two copies of each of seven different alpha-type and seven different beta-type subunits are assembled to form a stack of four seven-membered rings, giving the general structure alpha(1-7), beta(1-7), beta(1-7), alpha(1-7). By means of immunoelectron microscopy and chemical crosslinking of neighboring subunits, we have determined the positions of the individual subunits ...

We cross-sectionally examined the relationship between age, optic disc area, refraction, and gender and optic disc topography and retinal nerve fiber layer (RNFL) measurements, using optical imaging techniques. One eye from each of 155 Caucasian subjects (age range 23.0-80.8 y) without ocular pathology was included. Measurements were obtained by using the Heidelberg Retina Tomography (HRT), the...
