A new optical security system for image encryption based on a nonlinear joint transform correlator (JTC) in the Fresnel domain (FrD) is proposed. The proposal of the encryption process is a lensless optical system that produces a real encrypted image and is a simplified version of some previous JTC-based encryption systems. We use a random complex mask as the key in the nonlinear system for the...

Schizophrenia is a mental disorder associated with a variety of symptoms, including hallucinations, delusions, social withdrawal, and cognitive dysfunction. Impairments on decision-making tasks are routinely reported: evidence points to a particular deficit in learning from and revising behavior following feedback. In addition, patients tend to make hasty decisions when probabilistic judgments ...

conclusions right ventricular pacing increases the qt interval without increasing the jt interval. our results confirm that jtc, as an index of repolarization, is independent of ventricular depolarization. therefore, it can be applied for predicting qtc in patients with lbbb. results stimulation from the rva increased the qtc from 456.20 ± 38.63 ms to 530.67 ± 47.73 ms at a cl of 600 (p < 0.000...

OBJECTIVE Several studies have provided evidence for the claim that a subgroup of (schizophrenic) patients with current delusions share a jumping to conclusions (JTC) bias. The primary aim of the present study was to investigate whether currently deluded and non-deluded schizophrenic patients perform differently on three tasks tapping probabilistic reasoning. METHOD Probabilistic reasoning wa...

OBJECTIVE To report acute and mid-term electrocardiographic changes in patients with hypertrophic obstructive cardiomyopathy (HOCM) after alcohol ablation of the first large septal branch of the left anterior descending coronary artery; and to relate electrocardiographic data with the left ventricular outflow tract pressure gradients. PATIENTS Nine consecutive symptomatic patients with HOCM (...

BackgroundPulmonary hypertension (PH) in congenital heart disease (CHD) affects the patient prognosis. QRS and QTC intervals prolongation in ECG may exaggerate life-threatening dysrhythmia in these patients. We aimed to investigate the correlation between QRS, QTC and JTC intervals prolongation in ECG with PH in CHD children. Materials and MethodsIn a cross-sectional study tha...

Abstract Obesity is a global epidemiological problem that significantly contributes to the development of cardiovascular diseases. It proven factor for an increased risk overall mortality and occurrence sudden cardiac death (SCD). The disease accompanied by structural functional myocardium remodeling, which often results in ventricular repolarization abnormalities triggering life-threatening ar...

Optical image processing can derive significant benefits from the introduction of interferometric methods. The use of a shearing interferometer to yield the cosine Fourier transform of an object illuminated by spatially incoherent light is well known.'2 Other applications of the same interferometer include the sine transform'and the Hartley transform (HT) in coherent6'7 and incoherent8 illumina...

Monoclonal antibodies to various domains of human protein C were characterized, and the cross-reactivity of these antibodies with other vitamin K-dependent proteins was explored. Three antibodies, JTC-1, -2, and -3 reacted with protein C only in the presence of Ca2+ and were shown to bind to the light chain of protein C. It is suggested that these antibodies recognize a gamma-carboxyglutamic ac...

Sudden death is a possible occurrence for newborns younger than 1 year with severe aortic coarctation (CoA) before surgical correction. In our previous study, we showed a significant increase of QTc-D and JTc-D in newborns with isolated severe aortic coarctation, electrocardiographic parameters that clinical and experimental studies have suggested could reflect the physiological variability of ...
