Context: Ethanolamine plasmalogens (EPls) and choline plasmalogens (CPls) are classes of ethanolamine ether phospholipids (ePE) or choline ether phospholipids (ePC), respectively. EPls play crucial roles in maternal and breastfed infant bodies and stimulate gonadotropin secretion by gonadotrophs. Aims: To estimate changes in and importance of plasma concentrations of EPls and CPls, utilizing newly developed enzymatic fluorometric assays for ePE and ePC in postpartum Holstein cows. Methods: Plasma samples were collected 3 weeks before expected parturition until approximately 8 weeks after parturition (16 primiparous and 38 multiparous cows) for analysis. Key results: Plasma concentrations of ePE and ePC, most of which are plasmalogens, declined before and increased after parturition and stabilised near the day of the first postpartum ovulation (1stOV). From weeks 2 to 3 after parturition, third-parity cows exhibited ePE concentrations that were higher than those of other parity cows. The days from parturition to 1stOV correlated with days from parturition to conception. On the day of 1stOV, milk yield correlated with plasma concentration of both ePE and ePC, while ePC concentration correlated negatively with milk fat percentage. At the early luteal phase after 1stOV, plasma ePE concentration correlated with plasma anti-Müllerian hormone concentration (r = 0.39, P < 0.01), and plasma ePC concentration correlated with plasma follicle-stimulating hormone concentration (r = 0.43, P < 0.01). Conclusion: The concentrations of ePE and ePC changed dramatically around parturition and 1stOV, and then the concentrations correlated with the important parameters. Implications: The blood plasmalogen may play important roles in postpartum dairy cows.

McTaggart’s paradox and his A-theory and B-theory are basic notions in the contemporary philosophy of time. It is well known that the paradox was introduced by McTaggart’s paper called “The Unreality of Time” published in 1908, so that it has a one-hundred-year history. As for A-theory and B-theory, in contrast, McTaggart himself didn’t consider both of them at all. The notions of A-theory and B-theory came much later, 60 years after the paradox. Moreover, they had not been as popularized as they are today until quite recently, at least after the 1990s. This paper aims to trace the origin of the notions of A-theory and B-theory and show how the debates behind them, especially objections to “spatialising time,” form the notions.

We investigate symmetric equilibria of mutual reinforcement learning when both players alternately learn the optimal memory-two strategies against the oppo-nent in the repeated prisoners' dilemma game. We provide a necessary condi-tion for memory-two deterministic strategies to form symmetric equilibria. We then provide three examples of memory-two deterministic strategies which form symmetric mutual reinforcement learning equilibria. We also prove that mu-tual reinforcement learning equilibria formed by memory-two strategies are also mutual reinforcement learning equilibria when both players use reinforcement learning of memory-n strategies with n > 2.

Imitation is simple behavior which uses successful actions of others in order to deal with one’s own problems. Because success of imitation generally depends on whether profit of an imitating agent coincides with those of other agents or not, game theory is suitable for specifying situations where imitation can be successful. One of the concepts describing successfulness of imitation in repeated two-player symmetric games is unbeatability. For infinitely repeated two-player symmetric games, a necessary and sufficient condition for some imitation strategy to be unbeatable was specified. However, situations where imitation can be unbeatable in multi-player games are still not clear. In order to analyze successfulness of imitation in multi-player situations, here we introduce a class of totally symmetric games called unexploitable games, which is a natural extension of two-player symmetric games without exploitation cycles. We then prove that, for infinitely repeated unexploitable games, there exist unbeatable imitation strategies. Furthermore, we also prove that, for infinitely repeated non-trivial unexploitable games, there exist unbeatable zero-determinant strategies, which unilaterally enforce some relationships on payoffs of players. These claims are demonstrated in the public goods game, which is the simplest unexploitable game. These results show that there are situations where imitation is unbeatable even in multi-player games.

Since its inception, analytic philosophy has failed to attain dominance in Japan. However, the 21st century has seen analytic philosophy gain traction among Japanese philosophers. This paper, which examines the status quo of analytic philosophy in Japan since 2000, consists of two parts. The first part deals primarily with organizations—specifically, relevant associations, journals, conferences, universities, and publishers are illustrated. The second part explores key works in each area—namely, philosophy of science, philosophy of language, philosophy of logic and mathematics, philosophy of mind, and metaphysics. Key works in other areas are also briefly addressed.

China has been struggling with waste classification for decades, even after the mandatory implementation of relevant policy in 2017. However, the causes of the failing performance of waste classification in developing countries attract little scholarly attention. A recent literature review also identified a failure to classify waste in developing countries, noting that its causes have attracted little scholarly interest. In this paper, we would like to examine the current situation and issues of policies for classifying household waste in China's urban sector. In this paper, we conducted a questionnaire survey of residents in Changsha City, Hunan Province, examined their awareness of waste classification, classifying behavior, and their awareness of paying for waste reduction, elucidated the factors that affect them, and estimated the amount of willing to pay (WTP) for waste reduction. In this paper, endogenous factors are more significant influencing behaviors than exogenous factors.

Zero-determinant strategies are memory-one strategies in repeated games which unilaterally enforce linear relations between expected payoffs of players. Recently, the concept of zero-determinant strategies was extended to the class of memory-n strategies with n _ 1, which enables more compli-cated control of payoffs by one player. However, what we can do by memory-n zero-determinant strategies is still not clear. Here, we show that memory-n zero-determinant strategies in repeated games can be used to control condi-tional expectations of payoffs. Equivalently, they can be used to control ex-pected payoffs in biased ensembles, where a history of action pro_les with large value of bias function is more weighted. Controlling conditional expectations of payoffs is useful for strengthening zero-determinant strategies, because play-ers can choose conditions in such a way that only unfavorable action pro_les to one player are contained in the conditions. We provide several examples of memory-n zero-determinant strategies in the repeated prisoner's dilemma game. We also explain that a deformed version of zero-determinant strategies is easily extended to the memory-n case.

Zero-determinant strategies are a class of memory-one strategies in repeated games which unilaterally enforce linear relationships between payoffs. It has long been unclear for what stage games zero-determinant strategies exist. We provide a necessary and sufficient condition for the existence of zero-determinant strategies. This condition can be interpreted as the existence of two different actions which unilaterally adjust the total value of a linear combination of payoffs. A relation between the class of stage games where zero-determinant strategies exist and other class of stage games is also provided.

The quadratic unconstrained binary optimization (QUBO) problem is categorized as an NP-hard combinatorial optimization problem. The variable neighborhood search (VNS) algorithm is one of the leading algorithms used to solve QUBO problems. As neighborhood structure change is the central concept in the VNS algorithm, the design of the neighborhood structure is crucial. This paper presents a modified VNS algorithm called "B-VNS", which can be used to solve QUBO problems. A binomial trial was used to construct the neighborhood structure, and this was used with the aim of reducing computation time. The B-VNS and VNS algorithms were tested on standard QUBO problems from Glover and Beasley, on standard max-cut problems from Helmberg-Rendl, and on those proposed by Burer, Monteiro, and Zhang. Finally, Mann-Whitney tests were conducted using α = 0.05, to statistically compare the performance of the two algorithms. It was shown that the B-VNS and VNS algorithms are able to provide good solutions, but the B-VNS algorithm runs substantially faster. Furthermore, the B-VNS algorithm performed the best in all of the max-cut problems, regardless of problem size, and it performed the best in QUBO problems, with sizes less than 500. The results suggest that the use of binomial distribution, to construct the neighborhood structure, has the potential for further development.

To realize a stable and efficient wireless power transfer (WPT) system that can be used in any environment, it is necessary to inspect the influence of environmental interference along the power transmission path of the WPT system. In this paper, attempts have been made to reduce the influence of the medium with a dielectric and conductive loss on the WPT system using spiral resonators for resonator-coupled type wireless power transfer (RC-WPT) system. An important element of the RC-WPT system is the resonators because they improve resonant characteristics by changing the shape or combination of spiral resonators to confine the electric field that mainly causes electrical loss in the system as much as possible inside the resonator. We proposed a novel dual-spiral resonator as a candidate and compared the basic characteristics of the RC-WPT system with conventional single-spiral and dual-spiral resonators. The parametric values of the spiral resonators, such as the quality factors and the coupling coefficients between resonators with and without a lossy medium in the power transmission path, were examined. For the lossy mediums, pure water or tap water filled with acryl bases was used. The maximum transmission efficiency of the RC-WPT system was then observed by tuning the matching condition of the system. Following that, the transmission efficiency of the system with and without lossy medium was investigated. These inspections revealed that the performance of the RC-WPT system with the lossy medium using the modified shape spiral resonator, which is the dual-spiral resonator proposed in our laboratory, outperformed the system using the conventional single-spiral resonator.

This study aimed to clarify outcome of the public health nursing practice conducted under the influence of COVID-19. A self-administered anonymous questionnaire survey was performed for 4th grader students at University from 2018 through 2020. The investigation items consisted of basic attributes, impression of public health nurse activity, learning motivation and learning target items. We compared shortened clinical practice and online practice enforced in 2020 and before. For 217 effective answers,"A public health nurse was involved in practice sufficiently" was significantly low. In top learning achievement scores of 2020 included many of the items from the the learning target"Process of public health nursing activity" and "Role and function of public health center and municipalities. In 2018 and 2019, learning achievement degrees were over 80% in 94.3% of 53 items while on the other hand it was only 32.1% in 2020. Learning achievement degrees were less than 60% in no items in 2018 and 2019 while it was 15.1% in 2020. For the techniques of health service and health practice for which the learning achievement degree were low in 2020, it is necessary to support students so that they can acquire them as a public health nursing practice ability.

Abdominal incisional hernia is a frequent complication of open abdominal surgery. We herein report a rare case in which the left lateral segment of the liver prolapsed as the contents of an abdominal incisional hernia.The patient was a woman in her 80s whose chief complaint was abdominal protrusions. She had undergone abdominal surgery for gallstones 30 years ago. Computed tomography revealed abdominal incisional hernias in the upper abdomen, from which the left lateral segment of the liver and the transverse colon had prolapsed. Laparoscopic hernia repair surgery was performed under general anesthesia. The intraoperative findings showed the adhesion of the round ligament of the liver to the abdominal wall and transverse mesocolon. The prolapsed left lateral segment of the liver appeared as if being pulled upward by the round ligament of the liver and the poor formation of the triangle ligament. Two hernia orifices were repaired using two meshes. Recently, laparoscopic hernia repair surgery is increasing. Laparoscopic hernia repair surgery is useful to observe the abdominal cavity, details of hernia orifice and content, and the check of repair’s completion.

A 52-year-old-man visited hospital with right lower abdominal pain. We diagnosed acute appendicitis and intraperitoneal abscess. We decided to perform interval appendectomy and started antibacterial treatment. Antibacterial treatment was successful and the patient was discharged. Laparoscopic appendectomy was performed six month later. Only thickening of appendix mucosa was found in the specimen, but postoperative pathological diagnosis revealed goblet cell adenocarcinoma(GCA)of appendix. There was a risk factor associated with invasion depth T4, we performed ileocecal resection(D3)one month after the first surgery. The postoperative pathological examination result was pT4aN0M0 pStageⅡ.Recurrence has not been observed 18 months later. This case was an appendiceal GCA which was accidentally found in a specimen after interval appendectomy and treated by additional surgery. Infrequently, there are some reports of acute appendicitis associated with appendiceal tumor. In clinical practice, it is difficult to perform interval appendectomy for all appendicitis cases after conservative treatment, but it is suggested that for complicated appendicitis, we should perform interval appendectomy in consideration of age, ADL, and social background.

A 38-year-old woman was referred to our hospital with a complaint of left buttock pain. Contrast-enhanced computed tomography and magnetic resonance imaging showed a 7cm smooth mass on the anterior sacrum adjacent to the small intestine and mesentery. The mass was suspected to be a gastrointestinal stromal tumor of the small intestine;however, a definitive diagnosis from radiological and clinical findings was impossible. Laparoscopic visualization revealed that there was no lesion in the small intestine;the mass situated in the retroperitoneally, in contact with the anterior sacrum around the aortic bifurcation. With a diagnosis of retroperitoneal tumor, laparoscopic resection was performed simultaneously. An incision was made in sigmoid mesentery, and the tumor was detached and resected preserving the anterior fascia of the hypogastric nerve. Intraoperatively the surface of the tumor was confirmed to be smooth, and there was no infiltration around the tumor, which facilitated handling and manipulation of the tumor for resection. The patient was discharged without any complications and the pathological diagnosis was benign schwannoma. Anterior sacral retroperitoneal schwannomas are rare and difficult to diagnose preoperatively. In this case, successfully management was achieved via simultaneous laparoscopic observation and resection.

Wireless power transfer (WPT) systems have attracted considerable attention in relation to providing a reliable and convenient power supply. Among the challenges in this area are maintaining the performance of the WPT system with the presence of a human body and minimizing the induced physical quantities in the human body. This study proposes a magnetic resonant coupling WPT (MRC-WPT) system that utilizes a resonator with a grounded loop to mitigate its interaction with a human body and achieve a high-efficiency power transfer at a short range. Our proposed system is based on a grounded loop to reduce the leakage of the electric field, resulting in less interaction with the human body. As a result, a transmission efficiency higher than 70% is achieved at a transmission distance of approximately 25 cm. Under the maximum-efficiency conditions of the WPT system, the use of a resonator with a grounded loop reduces the induced electric field, the peak spatial-average specific absorption rate (psSAR), and the whole-body averaged SAR by 43.6%, 69.7%, and 65.6%, respectively. The maximum permissible input power values for the proposed WPT systems are 40 and 33.5 kW, as prescribed in the International Commission of Non-Ionizing Radiation Protection (ICNIRP) guidelines to comply with the limits for local and whole-body average SAR.

We performed this study to investigate whether serum cell-free DNA testing(liquid biopsy)of either methylated SEPT9 or methylated SST, which are possible biomarkers of HCC, in combination with AFP may improve clinical performance for the detection of HCC. Study subjects included 25 healthy controls, 15 patients with chronic liver disease without HCC, and 38 patients with HCC. Methylation level of serum cell-free SEPT9 and SST was measured by methylation-sensitive restriction enzymes followed by multiplex droplet digital polymerase chain reaction. According to receiver operating characteristic curve analysis to discriminate between non-HCC group(including control group and chronic liver disease without HCC group)and HCC group, area under the curve(AUC)was 0.73 by AFP and 0.73 by mSEPT9, whereas it was only 0.59 by mSST. Regarding combination tests, although negative predictive values were almost same between the AFP + mSEPT9 test and the AFP + mSST test(75.0% vs 72.2%),a positive predictive value of AFP + mSEPT9 test was higher than that of the AFP + mSST test(79.4% vs. 66.7%).In conclusions, methylated SEPT9 was a better companion marker of AFP for HCC screening than methylated SST.

先行研究では、技能実習生に関する日本語教育の問題点の1つとして、講習で教えられている日本語が作業現場で使われている日本語と相違していると指摘されている。しかし、具体的にどのような点で相違しているのかということについては明らかにされていない。技能実習生が作業現場で日本人の同僚からの指示を理解するためには、日本語の統語構造の特徴から、文末表現を理解することが欠かせないと考えられる。日本語の文末表現には、「発話の機能」を明示的に示す働きがある。命令か依頼かが文末表現を聞いて初めてわかるからである。そこで、本稿は鉄骨工場のような指示が多い作業現場をフィールドとし、そこでの、技能実習生に向けられた日本語母語話者の発話における文末表現の特徴を明らかにした。そのうえで、そこで明らかになった特徴と技能実習生向けの講習用教材の比較を通し、両者の、文末表現上の相違点を析出することを試みた。研究結果として、1)作業現場の発話には、言いさしが半数近くあり、よく使われていると言えるのに対し、講習用教材では、言い切りが主導的な地位を占めていること、2)作業現場では、普通体を主基調として、発話が進められているのに対し、講習用教材では、丁寧体を主使用文体としていること、3)作業現場では、「動詞等の∅形」の使用率は3分の1に足りないのに対し、講習用教材では「動詞等の∅形」の使用率は半数近くあること、4)作業現場では、相応の縮約形があるものについては、縮約形を使うのが一般的であるのに対し、講習用教材では、ほとんどの場合に、相応の縮約形があったとしても、元の形そのままで使われていることが明らかになった。このような状況を踏まえ、今後、講習において、作業現場で働く日本語母語話者の発話の文末表現をどのように導入し、教えたらいいのかについて、工夫が必要であると思われる。

The power transmission effi ciency of a resonatorcoupled wireless power transfer (RC-WPT) system with some angular misalignments is examined in this paper. In addition to conventional single-spiral resonators, the dual-spiral resonators which we have proposed are used in the RC-WPT system. It was confi rmed that the power transmission effi ciency of the RC-WPT system decreased with the increment of angular misalignments. However, it was shown that the decayed power transmission efficiency due to the angular misalignments could be recovered by adding the appropriate axial displac ements between transmitting (Tx) and receiving (Rx) units.
