We give a complete relation between the singular values and eigenvalues of a complex skew symmetric matrix in terms of multiplicative majorization and double occurrences of singular values and eigenvalues. Similar studies are given for matrices in the algebras spn(C) and spn(R).
The neural basis of feedback expectation, which is crucial in learning theory, has only been minimally studied. Stimulus-preceding negativity (SPN), an ERP component that appears prior to the presentation of feedback, has been proposed as related to feedback expectation. The present study showed, for the first time, amplitude modulations of the SPN component during learning acquisition in a tri...
Thoracoscopic needle aspiration is a good alternative for a centrally-located solitary pulmonary nodule (SPN) suspected of being lung cancer without severe pleural adhesion. The authors report the technique of thoracoscopic needle aspiration biopsy in a SPN just in the medial aspect of the truncus anterior pulmonary artery and the right upper lobe bronchus.
Impossible differential and zero correlation linear cryptanalysis are two of the most important cryptanalytic vectors. To characterize the impossible differentials and zero correlation linear hulls which are independent of the choices of the non-linear components, Sun et al. proposed the structure deduced by a block cipher at CRYPTO 2015. Based on that, we concentrate in this paper on the secur...
solitary pulmonary nodule (spn) is a frequent finding on the chest x-ray and computed tomography. nuclear medicine techniques play an important role in the diagnosis and management of spn. in the current review, we briefly will explain the different nuclear medicine modalities in this regard including positron emission tomography (pet) using 18-f-fdg, and 11-c-methionine, and single photon emis...
Editorials on a CT slice. Using 10 mm thick CT slices, the diagnostic yield from fiberoptic bronchoscopic procedures (FOB) was 60 percent for SPNs with the positive bronchus sign, and 30 percent for SPNs without this sign. Some SPNs were also scanned using 1.5 mm thick slices (thin-section CT), and the diagnostic yield of SPN without the positive bronchus sign dropped from 30 to 14 percent. Thi...
BACKGROUND Solitary pulmonary nodule (SPN) may show different presentation in tuberculosis (TB)-endemic countries. The aim of this study was to identify clinical and radiological predictors favoring benign or malignant SPN in TB-endemic region. METHODS Two hundred one SPNs in 201 consecutive Korean patients were included (< 3 cm in diameter, all confirmed by pathology or bacteriology, 93 beni...
Contrast-enhanced computed tomography (CECT) and positron emission tomography with 18-FDG (FDG-PET/CT) are used to identify malignant solitary pulmonary nodules. The aim of the study was to evaluate the accuracy of CECT and FDG-PET/CT in diagnosing the etiology of solitary pulmonary nodule (SPN). Eighty patients with newly diagnosed SPN >8 mm were enrolled. The patients were scheduled for eithe...
Aberrant expression of Beclin 1 and B-cell lymphoma-2 (Bcl-2) has been identified in a variety of human tumors; however, little information is available for pancreatic neoplasms. The present study analyzed the expression of Beclin 1 and Bcl-2 in pancreatic ductal adenocarcinoma (PDAC) and solid pseudopapillary neoplasm (SPN) of the pancreas, and evaluated their prognostic significance for PDAC....
