We have developed an event mixing technique to observe Bose-Einstein correlations （BEC） between two identical neutral pions produced in photo-induced reactions in the non-perturbative QCD energy region. It is found that the missing-mass consistency cut and the pion-energy cut are essential for the event mixing method to effectively extract BEC observables. A Monte Carlo （MC） simulation is used to validate these constraints and confirms the efficiency of this method. Our work paves the way for similar BEC studies at lower energies where the multiplicity of emitted bosons is limited.

Aim: recently, the role of feeding coparenting has gained attention in the child eating research field. The Feeding Coparenting Scale (FCS), a measure of how caregivers interact with their partners when feeding their children was developed in the United States in 2019. However, there is no valid and reliable measure to assess feeding coparenting among caregivers of school-aged children in Japan. Therefore, this study aimed to develop a Japanese version of the FCS (FCS-J) questionnaire for caregivers with school-aged children. Methods: This was a web-based cross-sectional survey completed by caregivers of children aged 10-12 years. A preliminary survey using interviews and a web-based survey was conducted and found that the translated items of the FCS into Japanese were understandable to Japanese people. The developed survey was administered to parents of children at an elementary school. The reliability of the survey was assessed using both test-retest reliability and internal consistency analysis. Exploratory factor analysis was used to test construct validity, and known population validity was examined in relation to attributes, marital satisfaction, and feeding tasks. results: Findings with 135 parents of school-aged children showed good internal reliability and validity of the FCS-J. The mean score for the overall FCS-J score was 46.2 (SD = 6.2), with Cronbach’s α of 0.72. For the subscales, Cronbach’s α ranged from 0.75 to 0.79. In sum, the present study’s results support the three-factor structure of the FCS in Japanese caregivers in Japan. Conclusions: The developed FCS-J was found to have a certain degree of reliability and validity. In this study, a Japanese version of the FCS-J was developed. .

用二维传声器阵列在风洞试验中所得声压级的空间分布,在道旁观测点对转向架的空气动力噪声进行了定量估算。为评定声压级,需要适当考虑噪声产生和声场的各种声学特性,如地面反射和转向架侧罩的插入损耗。采用数值方法计算了声压级的综合空间分布与全向传声器试验结果之间的传递函数。利用该传递函数可以估算新干线列车转向架空气动力噪声的声压级,并与现场测试结果进行比较。

The androgen receptor (Ar) is a critical target in all the clinical stages of prostate cancer. To identify a new Arinhibitor, we constructed a new screening system using the androgen-dependent growth of prostate cancer cell lines as ascreening indicator. We screened 50,000 culture broths of microorganisms using this screening system and found that thefermentation broth produced by a fungus inhibited androgen-dependent growth of human prostate cancer LNCaP cellswithout cytotoxicity. Purification of this culture medium was performed, and this resulted in deoxynortryptoquivaline(DNT) being identified as a novel inhibitor of Ar function. DNT showed potent inhibition of androgen-dependentgrowth of human prostate cancer LNCaP cells. The Ar competitor assay was performed, and DNT did not act as anAr antagonist. However, DNT inhibited Ar-dependent transcriptional activity and Ar nuclear translocation, itsuggested that the suppression of Ar function leads to inhibition activity against androgen-dependent growth.

本文在政策分析的基础上,建立VAr-BEKK-GArCH模型进行实证分析。首先,国际玉米价格的波动幅度比中国价格波动幅度大,临储政策取消后,中国价格波动幅度变大。其次,临储期间,中国价格的预期波动可以影响国际价格的波动,而国际价格的随机波动可以影响中国价格的波动。在生产者补贴期间,中国价格的预期波动和随机波动均可影响国际价格的波动。再次,中国价格的影响力在中国市场和进口市场占据主导地位,与国产玉米供给本国市场的数量地位相符。最后,中国玉米进口的不断增加将降低对本国市场价格的主导能力,需重视通过“期货+保险”规避价格风险,并分散玉米进口源,以提高市场主导力。
