  abstract  = {Isolated left ventricular non-compaction cardiomyopathy (LVNC) is a congenital myocardial disease characterized by excessive and prominent trabeculations in the left ventricle with deep intertrabecular recesses. Trabeculation is, however, a non specific finding which is present not only in LVNC but also in other cardiomyopathies like dilated cardiomyopathy (DCM) and even in healthy controls, therefore, differential diagnosis keeps puzzling clinicians. Therefore the present study aimed to comprehensively explore regional myocardial deformation properties in adult patients with isolated LVNC using strain and strain rate imaging derived from tissue Doppler imaging and 2D speckle tracking. It was proposed that the knowledge of deformation properties in LVNC would help to differentiate patients with LVNC and DCM. A total of 14 patients with LVNC, 15 patients with DCM, and 15 healthy controls were included in this study. The groups were matched for age and gender. Standard 2D echocardiography was performed in all subjects, and tissue Doppler imaging (TDI) of all ventricular walls was acquired using parasternal long axis, apical 4-chamber, 2-chamber, and apical long axis views. Deformation imaging data derived from both TDI and grey scale images were analyzed. Clinical and standard echocardiographic findings in patients with LVNC and DCM were similar. In patients with LVNC, hypertrabeculation was mostly located in the apical and mid segments of the left ventricle and strikingly more than in patients with DCM. The extent of non-compaction was poorly related to global left ventricular systolic function (LVEF) as well as regional myocardial function assessed by strain rate imaging. Regional myocardial systolic deformation in patients with LVNC was significantly impaired in the left and right ventricles in both longitudinal and radial direction. There was a striking difference on longitudinal myocardial systolic function between LVNC and DCM patients, i.e., an increasing strain and strain rate gradient from apex to base in patients with LVNC, whereas patients with DCM displayed a homogeneously decreased strain and strain rate in all segments. Results derived from 2D speckle tracking method were consistent with those from TDI method. Analysis of myocardial mechanical asynchrony revealed a lack of myocardial contraction synchrony in the LVNC and DCM patients. The time to systolic peak velocity was obviously delayed in these two patient groups. However, the mechanical asynchrony features were similar in patients with LVNC and DCM and could not serve for differential diagnosis. In conclusion, LVNC and DCM are both cardiomyopathies presenting reduced regional myocardial function and mechanical asynchrony. Nevertheless differential diagnosis can be made by analysis of hypertrabeculation as well as analysis of regional myocardial deformation pattern.},

  abstract  = {The charge transport properties of disordered organic and nanocrystalline inorganic semiconductors as well as their combinations have been investigated in regard to the charge carrier density employing field-effect-transistor structures. The results were discussed in the framework of different theoretical models. In organic semiconductors the presence of positional and energetic disorder determines the transport of charges through the respective thin films and interfaces. The electronic disorder is characterized by statistically distributed and localized transport sites which were shown to form a Gaussian density of states. In this electronic environment the charge transport occurs via thermally activated hopping between the localized states and therefore depends on the temperature and the local electric field. Particularly, a dependence of the carrier mobility on the charge carrier concentration is observed due to filling of tail states. Inorganic nanocrystalline semiconductors, however, are expected to present a different electronic structure: Within the volume of a nanocrystallite the semiconductor is assumed to reflect the electronic properties of the crystalline bulk material. However, the outer shell is characterized by a relatively large density of surface states and correspondingly bending of the energy bands, which creates an energetic barrier between the adjacent particles. In a nanocrystalline thin film this characteristic can be rate-limiting for the inter-particle carrier transport as reflected by reduced charge carrier mobility. The effective barrier height can be reduced by controlled doping of the nanocrystals which results in improved majority carrier transfer rates across the barrier. However, doping results in the simultaneous increase of the defect density and consequently to enhanced limitation of the mobility due to charge carrier scattering. In the experiments, thin films of commercially available p- and n-type organic semiconductors (P3HT, and two derivatives of PCBM) were investigated in field-effect transistor structures. Further, sol-gel synthesized n-type nanocrystalline-ZnO (nc-ZnO) with varied doping concentration (agent: aluminum Al\$^{3+}\$) was introduced in order to establish an alternative way of customizing the charge transport properties of the neat material and in combination with the organic polymer semiconductor P3HT.},

  abstract  = {Computationally categorizing Quran's chapters has been mainly confined to the determination of chapters' revelation places. However this broad classification is not sufficient to effectively and thoroughly understand and interpret the Quran. The chronology of revelation would not only improve comprehending the philosophy of Islam, but also the easiness of implementing and memorizing its laws and recommendations. This paper attempts estimating possible chapters' dates of revelation through their lexical frequency profiles. A hybrid statistical classifier consisting of stemming and clustering algorithms for comparing lexical frequency profiles of chapters, and deriving dates of revelation has been developed. The classifier is trained using some chapters with known dates of revelation. Then it classifies chapters with uncertain dates of revelation by computing their proximity to the training ones. The results reported here indicate that the proposed methodology yields usable results in estimating dates of revelation of the Quran's chapters based on their lexical contents.},
