Abstract In the presence of an MMC-HVDC system, current differential protection (CDP) has risk failure in operation under internal fault. addition, CDP may also incur security issues transformer (CT) saturation and outliers. this paper, a trajectory image-based algorithm is proposed for AC lines connected to stations using convolution neural network improved by channel attention mechanism (CA-C...

Emergent phases at the interfaces in strongly correlated oxide heterostructures display novel properties not akin to those of constituting materials. The interfacial ferromagnetism (LaMnO3)m/(SrMnO3)n (LMO)m/(SMO)n superlattices (SLs) with antiferromagnetic bulk LMO and SMO layers is believed be a result charge transfer (CT). By using situ optical ellipsometry, it demonstrated directly that CT ...

With the widespread use of cross-sectional imaging, many renal masses are incidentally found. These need to be accurately characterized as either lesions potentially requiring surgery such as renal cell carcinoma or as nonsurgical lesions including cyst, angiomyolipoma, abscess, hematoma, lymphoma, or metastasis. MRI and CT can both accurately characterize renal masses and frequently, both exam...

Computerized tomography (CT) and magnetic resolution imaging (MRI) are the medical imaging modalities to deliver cross-sectional images of the human body. In the last decade, CT has become the most frequently used imaging modality for the evaluation of the jaw for dental implants. Furthermore, image reformatting software has been developed in order to obtain a correct preoperative diagnosis ...

results roc-derived spo2 threshold of ≤ 94% can predict hypoxemia (pao2 < 60 mmhg) with a sensitivity of 100% and a specificity of 95%. furthermore, there are associations between the roc-derived spo2 threshold of ≤ 97% and detection of hypoxemia (pao2 < 70 mmhg) with a sensitivity of 100% and a specificity of 46%. the accuracy of pulse oximetry was not affected by the severity of liver disease...

Core flooding experiments are used for testing enhanced oil recovery strategies (EOR) on a laboratory scale. In a typical core flooding experiment, the core plug contains oil, water and potential EOR agents. It is of importance to understand the multiphase flow of these liquid inside the porous rock formation. The combination of X‐ray CT scanning and image analysis has been used to study multip...

Acute flank pain is a frequent clinical presentation encountered in emergency departments, and a work-up for obstructive urolithiasis in this setting is a common indication for computed tomography (CT). However, imaging alternatives to CT for the evaluation of renal colic are warranted in some clinical situations, such as younger patients, pregnancy, patients that have undergone multiple prior ...
