The torque in the Taylor-Couette flow for radius ratios η≥0.97, with smooth or grooved wall static outer cylinders, is studied experimentally, with the Reynolds number of the inner cylinder reaching up to Re_{i}=2×10^{5}, corresponding to the Taylor number up to Ta=5×10^{10}. The grooves are perpendicular to the mean flow, and similar to the structure of a submersible motor stator. It is found that the dimensionless torque G, at a given Re_{i} and η, is significantly greater for grooved cases than smooth cases...

In β titanium alloys, the β stabilizers segregate easily and considerable effort has been devoted to alleviate/eliminate the segregation. In this work, instead of addressing the segregation problems, the segregation was utilized to develop a novel microstructure consisting of a nanometre-grained duplex (α+β) structure and micrometre scale β phase with superior mechanical properties. An as-cast Ti-9Mo-6W alloy exhibited segregation of Mo and W at the tens of micrometre scale. This was subjected to cold rolling and flash annealing at 820 o C for 2 and 5 mins...

BACKGROUND & AIMS: Acute episodes of renal dysfunction or acute kidney injury (AKI) in cirrhotic patients with ascites are mostly precipitated by an acute event. The prevalence of un-precipitated AKI in stable ascitic cirrhotic patients is unknown. The aims of this study were to determine (i) the prevalence of un-precipitated AKI in stable cirrhotics with ascites and (ii) any predictive factors for its development. METHODS: A total of 1115 stable cirrhotic patients with mild liver and renal dysfunction but varying degrees of ascites severity from 3 previous satavaptan vs placebo randomized controlled trials (Group A, ascites requiring diuretics but not paracentesis; Group B, ascites requiring frequent paracentesis; Group C, refractory ascites) were included...

Photocatalytic generation of H2 and O2 by water splitting remains a great challenge for clean and sustainable energy. Taking into the consideration promising heterojunction photocatalysts, analogous energy issues have been mitigated to a meaningful extent. Herein, we have architectured a highly efficient bifunctional heterojunction material, i.e., p-type Co(OH)2 platelets with an n-type ZnCr layered double hydroxide (LDH) by an ultrasonication method. Primarily, the Mott-Schottky measurements confirmed the n- and p-type semiconductive properties of LDH and CH material, respectively, with the construction of a p-n heterojunction...

BACKGROUND: Following complete resection of pN2 non-small cell lung cancer (NSCLC), national guidelines recommend either sequential (sCRT) or concurrent chemoradiotherapy (cCRT). This is the largest study to date evaluating survival between both approaches. In sCRT patients, sequencing 'chemotherapy first' versus 'radiotherapy first' was also addressed. METHODS: The National Cancer Data Base (NCDB) was queried for patients with primary NSCLC undergoing surgery (without neoadjuvant radiotherapy or chemotherapy), pN2 disease with negative surgical margins, and receiving postoperative CRT...

PURPOSE: Thyroid dysfunction affects the outcomes of atrial fibrillation (AF) catheter ablation. However, it remains unclear if the variations in thyroid function, especially in the triiodothyronine levels, are associated with AF recurrence in euthyroid subjects. This study investigated the associations of thyroid hormone levels with arrhythmia recurrence after AF catheter ablation in euthyroid patients. METHODS: A total of 1115 consecutive AF patients who underwent catheter ablation were prospectively enrolled and had their thyroid function measured prior to the procedure...

Fiber lasers with flexible spectral manipulation property could provide a flexible tool for scenes where the temporal coherence property accounts, for example, coherent sensing/communication and nonlinear frequency conversion. Due to the good laser performance and relative simplicity of implementation, random fiber lasers (RFLs) based on random distributed feedback and Raman gain have earned more and more attention in the past few years, and a variety of RFLs with substantially different spectral properties have been developed...

A central question in the metacognitive literature concerns whether the act of making a metacognitive judgment alters one's memory for the information about which the judgment was made. Dougherty, Scheck, Nelson, and Narens (2005, Memory & Cognition, 33(6), 1096-1115) attempted to address this question by having participants make either retrospective confidence judgments (RCJs; i.e., evaluations of past retrieval success), judgments of learning (JOLs; i.e., predictions of future retrieval success), or no explicit judgments...

Species of Pomacea, commonly known as apple snails, are native to South America, and have become widely distributed agricultural and environmental pests in southern China since their introduction in the 1980s. However, only since 2010 have researchers recognized that at least two species, P. canaliculata and P. maculata, are present in China. Although impacts of apple snails have been extensively documented, confusion still persists regarding current distributions and origin of the species in China. To resolve this confusion, we used phylogenetic and phylogeographic methods to analyze 1464 mitochondrial COI sequences, including 349 new sequences from samples collected in southern China and 1115 publicly available sequences from snails collected in the native and introduced ranges...

BACKGROUND: The Barrow Neurological Institute (BNI) scale is a novel quantitative scale measuring maximal subarachnoid hemorrhage (SAH) thickness to predict delayed cerebral ischemia (DCI). This scale could replace the Fisher score, which was traditionally used for DCI prediction. OBJECTIVE: To validate the BNI scale. METHODS: All patient data were obtained from the prospective aneurysmal SAH multicenter registry. In 1321 patients, demographic data, BNI scale, DCI, and modified Rankin Scale (mRS) score up to the 1-yr follow-up (1FU) were available for descriptive and univariate statistics...
