Deformation-based morphometry (DBM) is a useful technique to detect morphological differences over the entire brain since it analyses positional differences between every voxel and a standard brain. In this report we compare DBM to semimanual tracing of brain ventricles in a population of 39 patients with schizophrenia. High-resolution T(1)-weighted magnetic resonance images were obtained and p...

A new approach to suppressing the four-wave mixing (FWM) crosstalk by using the pairing combinations of differently linear-polarized optical signals was investigated. The simulation was conducted using a four-channel system, and the total data rate was 40 Gb/s. A comparative study on the suppression of FWM for existing and suggested techniques was conducted by varying the input power from 2 dBm...

Due to the complexity of the physical mechanism of lightning and mathematical formula, Parameter range and large amount of calculation, at present the mathematical model of lightning simulation is always empirical or inconsistent with the physical properties of lightning. In order to bring down the complexity, and to advance physical properties, of the traditional lightning model the paper carr...

The effect of luminescent enhancement under exchange the auxiliary ligand in Europium(III) tris(1,3-diphenyl-1,3-propanedionato) monohydrate was investigated by steady-state and time-resolved transient absorption spectroscopy. excited state relaxation dynamics this complex analysed through a comparison experimental data obtained for several model compounds, namely Eu(DBM)3·NH3, Eu(DBM)3.EDA, Eu...

data transmission in optical systems and increased transmission distance capacity benefit by using optical amplification wavelength division multiplexing (wdm) technology. the combination of four waves (fwm) is a non-linear effect in the wavelength division multiplex (wdm), when more than two wavelengths of light in a fiber launch will occur. fwm amount depends on the channel, the channel spaci...

OBJECTIVES To increase the efficacy and reduce the toxicity of cancer therapy. METHOD The DBM with MLT (melatonin), Retinoids, vitamins E, D3, and C has a differentiating, cytostatic, antiangiogenic, immunomodulating, factorially synergic effect, at the same time reinforcing those functions that Physiology considers essential for life. With Somatostatin and/or its analogues, the DBM has an an...
