Unveiling Consonant Harmony: Nonlexical reduplication in English

There is a lack of strong diachronic evidence in English phonology to demonstrate consonant harmony (hereafter CH) in reduplication (Fikkert et al. 2005; Goad & Buckley 2006; Hale & Reiss 2008; Pater & Werle 2003; Rose 2000; Wolfram & Johnson 1982). In the present study, we investigated CH in synchronic settings wherein native English speakers were asked to produce a euphonious pseudo reduplicant from a nonce base in uncontrolled and controlled experiments. The results of the experiments indicated that, in English, consonantal assimilations might have a hierarchical structure when CH is present in the synchronic formation of a rhyming reduplicant. Taken holistically, these findings suggest that the rate of coronal assimilation exceeds that of labial assimilation. The occurrence of dorsal assimilation may be restricted even further by the scarcity of word-initial dorsal onsets that meet the requirements for rhyming reduplication

Trial of Sportswear Type ECG Sensor Device for Cardiac Safety Management during Marathon Running

Cardiac arrest has been reported during participation in several sports. Of these sports, marathon running is a particularly popular sport but imposes high cardiac load. Indeed, its popularity has been growing worldwide. Risk of cardiac arrest during marathon races is also expected to increase. Several studies have recorded electrocardiographic (ECG) information during marathon races to protect athletes from cardiac arrest. Although evaluable ECG data have been obtained and analyzed, cost-effectiveness of the system, data quality, and clinical significance remain inadequate. This report is the first to describe an economical electrocardiograph built into a T-shirt for use during marathon race. Twenty healthy runners aged 20 to 59 years (mean 36 years) wore the ECG device while running. The ECG data were monitored and analyzed to assess the observed frequencies of specified arrhythmias and the sections of the marathon in which the arrhythmias occurred. Of the ECG data obtained from 14 runners who completed the full marathon, six ECG datasets were evaluable. In some runners, there was inadequate contact between the electrode and body surface or poor Bluetooth connection between the ECG wireless transmitter and smartphone. Regarding arrhythmia analysis, all evaluable data that were analyzed showed some rhythm fluctuations. In conclusion, this economical T-shirt type ECG sensor provided evaluable ECG data during marathon races, although the evaluable rate was not high. The data were used to analyze specified arrhythmias, but some difficulties were encountered. The ECG sensor did not function properly because of a system error. The ECG sensor was not adequately moistened to record ECGs accurately. Moreover, some runners chose an unsuitable shirt size, which impaired the stability and strength of the electrode–skin contact. These shortcomings produced noise in the ECG data, which made it difficult to analyze arrhythmias. The next step will be to solve these problems and acquire data from a large number of runners

Cloning and sequencing analysis of whole Spiroplasma genome in yeast

Cloning and transfer of long-stranded DNA in the size of a bacterial whole genome has become possible by recent advancements in synthetic biology. For the whole genome cloning and whole genome transplantation, bacteria with small genomes have been mainly used, such as mycoplasmas and related species. The key benefits of whole genome cloning include the effective maintenance and preservation of an organism's complete genome within a yeast host, the capability to modify these genome sequences through yeast-based genetic engineering systems, and the subsequent use of these cloned genomes for further experiments. This approach provides a versatile platform for in-depth genomic studies and applications in synthetic biology. Here, we cloned an entire genome of an insect-associated bacterium, Spiroplasma chrysopicola, in yeast. The 1.12 Mbp whole genome was successfully cloned in yeast, and sequences of several clones were confirmed by Illumina sequencing. The cloning efficiency was high, and the clones contained only a few mutations, averaging 1.2 nucleotides per clone with a mutation rate of 4 × 10−6. The cloned genomes could be distributed and used for further research. This study serves as an initial step in the synthetic biology approach to Spiroplasma

高等学校共通教科情報科の知識体系に関する一考察

2022年度より，高等学校の「共通教科情報科」は，必履修科目の「情報Ｉ」と選択科目の「情報Ⅱ」が設置され，すべての高校生が，プログラミングなどを含む情報の科学的な理解を主とした「情報Ｉ」を履修することになる．また，2025年度入試から「情報Ｉ」が大学入学共通テストで出題されることが正式に決定された．これにより，各大学の個別入試においても入試科目に「情報」が設置される可能性が増してきた．大学入学試験として情報を出題するためには，大学など出題する側と，受験する高等学校側で，出題内容や範囲，用語などの共通な知識体系が必要となる．しかし現在はまだ，「情報科」の知識体系は明確に定められていない．そこで，本研究では，知識体系の明確化を目標として，「情報Ｉ」の教科書で用いられる用語から知識体系に関する考察を行う．Starting in 2022, the compulsory subject “Informatics I” and the elective subject “Informatics II” will be taught in high school. All high school students will take “Informatics I”, which focuses on the scientific understanding of information, including programming. In addition, it was formally decided that “Informatics I” will be a new subject on the Common Test for University Admissions. Even in the individual entrance examinations of each university, there is an increasing possibility that “Informatics” will appear as one of the entrance examination subjects. To introduce “Informatics” to university entrance exams, a common body of knowledge such as the content, scope, and conditions of the questions is required for both universities, which create the exam questions, and high schools, which take the exams. However, this body of knowledge is not clearly defined. Therefore, in this study, for the purpose of clarifying the body of knowledge, we investigate the terms used in textbooks for “Informatics I.
