We study entanglement in a valence-bond solid state, which describes the ground state of an Affleck-Kennedy-Lieb-Tasaki quantum spin chain, consisting of bulk spin-1's and two spin-1/2's at the ends. We characterize entanglement between various subsystems of the ground state by mostly calculating the entropy of one of the subsystems; when appropriate, we(More)
INTRODUCTION Urine neutrophil gelatinase-associated lipocalin (uNGAL) is a rapidly emerging biomarker for early detection of acute kidney injury (AKI). We aimed to investigate the prevalence and prognostic value of the early uNGAL in patients with AKI induced by sepsis. METHODS In this prospective cohort study, we analyzed the case records of 126 septic(More)
It is well known that orthogonal quantum states can be distinguished perfectly. However, if we assume that these orthogonal quantum states are shared by spatially separated parties, the distinguishability of these shared quantum states may be completely different. We show that a set of linearly independent quantum states [formula: see text] where U(m,n) are(More)
BACKGROUND & AIMS Pinaverium bromide (pinaverium) is an antispasmodic commonly used to treat irritable bowel syndrome (IBS), but there has been no convincing evidence for its effectiveness and safety. We evaluated these in a prospective, double-blind, placebo-controlled trial. METHODS Patients with IBS, based on Rome III criteria, were assigned randomly(More)
Context in image is crucial for scene labeling while existing methods only exploit local context generated from a small surrounding area of an image patch or a pixel, by contrast long-range and global contextual information is ignored. To handle this issue, we in this work propose a novel approach for scene labeling by exploring multi-level contextual(More)
BACKGROUND Acute pancreatitis is one of the rare complications of hemorrhagic fever with renal syndrome (HFRS), which easy to be misdiagnosed as acute abdomen, usually critically ill, poor treatment effect, highly mortality. In this study, we retrospectively analyzed to explore the clinical characteristics, 12 cases of hemorrhagic fever with renal syndrome(More)
The problem of local distinguishability of quantum states shared by distant parties has attracting considerable attentions recently. A number of interesting and often counterintuitive results have been obtained. It should be clear that orthogonal quantum states can be distinguished, while non-orthogonal states can only be distinguished probabilistically if(More)
PURPOSE To evaluate the accuracy of diffusion-weighted imaging (DWI) in comparison to contrast-enhanced, fat-suppressed T1 -weighted imaging (CET1WI) in detecting acute optic neuritis (ON). MATERIALS AND METHODS The clinical data and magnetic resonance imaging (MRI) findings of 42 patients who presented with decreased vision were retrospectively reviewed.(More)
Bone marrow-derived mesenchymal stem cells (BMSCs) are attractive candidates for tissue regeneration and immunoregulation in inflammatory bowel disease. However, their in vivo reparative capability is limited owing to barren efficiency of BMSCs to injury region. Stromal cell-derived factor (SDF-1) plays an important role in chemotaxis and stem cell homing(More)
