With the vast amount of digitized textual materials now available on Internet, it is almost impossible for people to absorb all pertinent information in a timely manner. To alleviate problem, we present novel approach extracting hot topics from disparate sets documents published given time period. Our technique consists two steps. First, terms are extracted by mapping their distribution over time. Second, based terms, key sentences identified and then grouped into clusters that represent...

Recently, mutations in the epidermal growth factor receptor (EGFR) gene nonsmall cell lung cancer (NSCLC) patients were reported to correlate with gefitinib response. Less than 30% of NSCLC are surgically resectable; however, molecular analysis has rely on nonsurgical diagnostic tissue samples. The objective this study is investigate EGFR mutation needle biopsy/aspiration samples and its correlations response patients' survival. was assessed from DNA 63 paraffin-embedded small specimens 62...

Background It is important to select appropriate targeted therapies for subgroups of patients with lung adenocarcinoma who have specific gene alterations. Methods This prospective study was a multicenter project conducted in Taiwan assessment genetic tests. Five oncogenic drivers, including EGFR, KRAS, BRAF, HER2 and EML4-ALK fusion mutations, were tested. BRAF mutations assessed by MALDI-TOF MS (Cohort 1). translocation tested Ventana method EGFR-wild type 2). Results From August 2011...

A green supply chain requires suppliers to consider products and related environmental management simultaneously include the principle of protection in mechanisms. The purpose is promote enhance market competitiveness. When industries companies can establish a set criteria for assessing suppliers, efficiency resource use be improved, consumption reduced, corporate image enhanced. On basis chain, this study developed green-supplier evaluation integrated decision-making trial laboratory method...

Extractive text or speech summarization manages to select a set of salient sentences from an original document and concatenate them form summary, enabling users better browse through understand the content document. A recent stream research on extractive is employ language modeling (LM) approach for important sentence selection, which has proven be effective performing in unsupervised fashion. However, one major challenges facing LM how formulate models accurately estimate their parameters...

Abstract Background Sarcopenia, characterized by reduced skeletal muscle mass and strength, is a significant risk factor for poor surgical outcomes in lung cancer patients. Accurate preoperative sarcopenia assessment crucial optimizing planning postoperative care. While abdominal CT at the lumbar 3 (L3) vertebral level gold standard, chest scans, routinely used screening staging, do not include this region. Whether thoracic measurements can reliably substitute L3-based assessments remains...

Summary The import of protein into chloroplasts is mediated by translocon components located in the chloroplast outer (the Toc proteins) and inner Tic envelope membranes. To identify intermediate steps during active import, we used sucrose density gradient centrifugation blue‐native polyacrylamide gel electrophoresis (BN‐PAGE) to complexes associated with precursor proteins under conditions instead arrested binding conditions. Importing solubilized membranes formed a two‐peak distribution...

Unsupervised discovery of acoustic tokens from audio corpora without annotation and learning vector representations for these have been widely studied.Although techniques shown successful in some applications such as query-byexample Spoken Term Detection (STD), the lack mapping relationships between discovered real phonemes limited down-stream applications.This paper represents probably first attempt towards goal completely unsupervised phoneme recognition, or signals to sequences...

We propose a simple method for automatic speech recognition (ASR) by fine-tuning BERT, which is language model (LM) trained on large-scale unlabeled text data and can generate rich contextual representations. Our assumption that given history context sequence, powerful LM narrow the range of possible choices signal be used as clue. Hence, comparing to conventional ASR systems train acoustic (AM) from scratch, we believe simply BERT model. As an initial study, demonstrate effectiveness...

People who work out at home use social media obtain knowledge, learning ability limited. Incomplete likely lead injury, a cheap, timely, accurate...

Tumor recurrence is the most common cause of disease failure after surgical resection in early‐stage lung adenocarcinoma. Identification clinically relevant prognostic markers could help to predict patients with high risk recurrence. A meta‐analysis available adenocarcinoma microarray datasets revealed that T ‐ LAK cell‐originated protein kinase ( TOPK ), a serine/threonine kinase, overexpressed cancer. Using stable cell lines overexpression or knockdown , we have shown can promote...

Ever-increasing amounts of publicly available multimedia associated with speech information have motivated spoken document retrieval (SDR) to be an active area intensive research in the processing community. Much work has been dedicated developing elaborate indexing and modeling techniques for representing documents, but only little improving query formulations better needs users. The latter is critical success a SDR system. In view this, we present this paper novel use relevance language...
