This paper analyzes the impact of higher-order inference (HOI) on task coreference resolution. HOI has been adapted by almost all recent resolution models without taking much investigation its true effectiveness over representation learning. To make a comprehensive analysis, we implement an end-to-end system as well four approaches, attended antecedent, entity equalization, span clustering, and cluster merging, where latter two are our original methods. We find that given high-performing...

Abstract To evaluate the repeatability of corneal biomechanical parameters in normal and keratoconus eyes, explore factors that affects repeatability, further assess diagnostic ability new parameters. Seventy-seven eyes 47 patients 77 right subjects were recruited current study. All participants received three repeated measurements with 2 to 5 minutes interval. The interclass correlation coefficient (ICC), Cronbach’ α (RC) evaluated. liner regression analysis was used identify affect linear...

Second-pass rescoring is an important component in automatic speech recognition (ASR) systems that used to improve the outputs from a first-pass decoder by implementing lattice or n-best re-ranking. While pretraining with masked language model (MLM) objective has received great success various natural understanding (NLU) tasks, it not gained traction as for ASR. Specifically, training bidirectional like BERT on discriminative such minimum WER (MWER) been explored. Here we show how train...

To evaluate the independent and interactive effects of eye rubbing atopy on keratoconus (KC) in central China.A total 330 KC patients controls were recruited case-control study. Eye history recorded through face-to-face interviews. The association between rubbing, atopy, analyzed by logistic regression, odds ratios (OR), relative excess risk due to interaction (RERI), attributable proportion (AP), synergy (S) index, 95% confidence intervals (95% CI) calculated.A 228 (69.09%) had an history,...

Background: Homocysteine (Hcy) plays an important role in vascular function and Hcy level contributes to pathogenesis of ischemic stroke (IS). MTHFR gene polymorphism may have effects on IS risks by influencing the metabolic pathway. In present study, a case–control study was designed evaluate relationship among C677Tpolymorphism, plasma level, susceptibility Chinese population. Methods: A total 300 patients with 261 matched control subjects were recruited. Plasma concentration determined...

We investigate the clinical history, past medical and risk status in women with benign intraductal papillomas(IDP). observed an upgrade rate of 3.9% to ductal carcinoma situ (DCIS) 10.7% a high-risk lesion. Prior or concurrent atypia cancer had significant increase upgrade. Surgical excision papillomas is recommended especially patients history malignancy.

Abstract Background Currently, Saphenous vein (SV) and internal thoracic artery (ITA) are still the most common graft materials in Coronary Artery Bypass Grafting (CABG) whereas SV have a lower long-term patency than ITA. Vascular smooth muscle cells (VSMCs) phenotype conversion, proliferation migration may play key role mechanism of restenosis. To explore differential gene expression profile VSMCs from ITA will help to further elucidate restenosis after CABG provide new thread therapy....

Purpose . The study aimed to evaluate the visual quality of forme fruste keratoconus (FFK) and mild moderate by using an optical analysis system II (OQAS-II) explore correlation between parameters disease progression. Methods Twenty-one normal eyes, twenty-one FFK eyes were included in this prospective study. parameters, such as object scatter index (OSI), modulation transfer function cutoff (MTF cutoff), strehl ratio (SR), OQAS-II values at contrasts 100% (OV-100), 20% (OV-20), 9% (OV-9),...

Numbers are essential components of text, like any other word tokens, from which natural language processing (NLP) models built and deployed. Though numbers typically not accounted for distinctly in most NLP tasks, there is still an underlying amount numeracy already exhibited by models. For instance, named entity recognition (NER), treated as with distinct tags. In this work, we attempt to tap the potential state-of-the-art transfer their ability boost performance related downstream tasks...
