  • Anaplastic thyroid cancer (ATC) belongs to the most malignant and rapidly progressive human thyroid cancers and its prognosis is very poor. Also, it shows high resistance to cancer treatments, so that effective treatment for ATC has not been found to date, and virtually all patients terminate their life rapidly after diagnosis. Although targeted treatment of genetic alterations has emerged as an extremely promising approach to human cancers, such as BRAF in metastatic melanoma, it remains unclear that how commonly genomic alterations are influenced in ATC tumorigenesis. In recent years, genome wide approaches have been exploited to find genetic alterations associated with complex diseases, including cancer. Here, we reviewed the comprehensive genetic alterations in ATC and recent approaches in the context of identifying genomic alterations associated with ATC. Since surprisingly few reports have been published on the genome wide study of ATC, this review puts emphasis on the urgent needs of genomic research for the prevention and treatment of ATC.

  • The performance of machine learning algorithms significantly depends on how a configuration of hyperparameters is identified and how a neural network architecture is designed. However, this requires expert knowledge of relevant task domains and a prohibitive computation time. To optimize these two processes using minimal effort, many studies have investigated automated machine learning in recent years. This paper reviews the conventional random, grid, and Bayesian methods for hyperparameter optimization (HPO) and addresses its recent approaches, which speeds up the identification of the best set of hyperparameters. We further investigate existing neural architecture search (NAS) techniques based on evolutionary algorithms, reinforcement learning, and gradient derivatives and analyze their theoretical characteristics and performance results. Moreover, future research directions and challenges in HPO and NAS are described.

  • Recent advances in perinatal care have resulted in improved survival of extremely low birth weight infants (ELBWI). However, bronchopulmonary dysplasia (BPD) remains one of the major complications in ELBWI. BPD was originally described over 40 years ago; the clinical characteristics, epidemiology, and pathogenesis of BPD have changed markedly through this period. In this article, I have reviewed recent progress in research concerning the clinical presentation and characteristics, epidemiology, and pathogenesis of BPD.

  • With the recent emergence of foldable electronic devices, interest in flexible organic memory is significantly growing. There are three types of flexible organic memory that have been researched so far: floating-gate (FG) memory, ferroelectric field-effect-transistor (FeFET) memory, and resistive memory. Herein, performance parameters and operation mechanisms of each type of memory device are introduced, along with a brief summarization of recent research progress in flexible organic memory.

  • We review the recent SAXS activity on the 1.5-GeV electron storage ring at the National Synchrotron Radiation Research Center (NSRRC). Typical measurements featuring in grazing incident SAXS for soft materials are illustrated. Complex measurements using simultaneous SAXS/DSC and SAXSIWAXS for the correlations between the crystallization and mesoscale ordering in a polymer blend and a polypeptide-block-polypseudorotaxane diblock copolymer are presented. We also introduce a dedicated SAXS beamline which is planned at NSRRC.

  • Amid the booming research on new and renewable energy, the photovoltaic(PV) industry has been growing around the PV advanced countries such as Japan, Germany, Europe and USA. In recent years, China became a strong performer in the world PV market share, increasing solar cell production rapidly. Both world solar cell and module production and installation rose steadily in 2007 like recent bumper years. In 2007, the PV industry produced 4.28GW and the installations reached a record high of 2.83GW, representing growth of 60percent over the previous year.

  • In this study, Network Text Analysis was performed on 1,752 articles which had been published in recent 7 years and drew the subject concept distribution and their relations in Library and Information Science research areas. Furthermore, for analyzing more recent trends and changing aspects, this study performed secondary analysis based on 482 articles published in recent 2 years. Results show that "public library", and "academic library" concepts were most frequently studied in the field and "evaluation", "education", and "web" concepts showed the highest-degree centrality during the recent 7 years. In the result of recent two years analysis, "web", and "classification" concepts showed high frequency and "user", and "public library" showed an improvement in high degree centrality.
