Background: The electrical dose selected for electroconvulsive therapy (ECT) must have an acceptable efficacy and no or minimal cognitive side-effects. We evaluated the clinical efficacy and cognitive side-effects of ECT in relation to the stimulus dose administered. Method: This study assessed 71 depressed patients who were treated with bilateral ECT. For evaluation of depressive and cognitive...
Powder bed fusion of metals (PBF-LB/M) is the most commonly used additive manufacturing process for layerwise production metal parts. Although technology has developed rapidly in recent years, manufactured parts still lack consistent quality primarily owing to process-inherent variability, and effective sensing technologies enabling ability control during part production. Thus, there are high c...
the ac electrical behaviour of nano porous silicon (psi) with tio2 thin films was examined over the range of frequency 102 to 105 hz. porous silicon (psi) layers were obtained by electrochemical etching in hf solution and tio2 thin films were deposited on psi substrates by using electron beam evaporation technique at room temperature. the porosity of psi layer was found by using the gravimetric...
Delay and noise estimation of CMOS logic gates driving coupled resistive-capacitive interconnections
The e!ect of interconnect coupling capacitance on the transient characteristics of a CMOS logic gate strongly depends upon the signal activity. A transient analysis of CMOS logic gates driving two and three coupled resistive}capacitive interconnect lines is presented in this paper for di!erent signal combinations. Analytical expressions characterizing the output voltage and the propagation dela...
A quantum capacitance is calculated for a single wall carbon nan otube in a eld e ect device The calculation is performed on a base of a continuum model taking into account full microscopics A general ex pression for the atomistic capacitance of a nanotube of arbitrary shape is derived The result is useful for modeling of electromechanical action of a nanotube device and for nanotube electronic...
In order to confirm the accuracy of ECT (emission computed tomography) scanning imaging in the diagnosis of lung histoplasmosis is higher than CT (computed tomography) scan. We retrospect a lung histoplasmosis patient, he was examined by the CT scan and ECT scanning, respectively. Results showed that lung cancer for CT diagnosis and large benign lesions for F-FDG (F-fluorodeoxyglucose) ECT diag...
