    • 摘要: This paper formulates the light timing calculations for each interferometer arm;one that is parallel to the direction of motion of the interferometer through space and the other that is perpendicular. The calculations are done for a vacuum-mode interferometer and then for a gas-mode interferometer. The calculations show that no light timing difference is detectable in a vacuum-mode interferometer, but once an optical medium is present in the light path down the arms of the interferometer, this is no longer the case and a timing difference is detectable. Further to this, the timing equations obtained from the analysis are used to model the historical experiments of Michelson-Morley and Miller (Mt Wilson) and predictions are made by the model that accurately match the actual recorded results from those experiments. Thus, this timing analysis confirms that there is a light speed anisotropy in a reference frame that is moving through space, indicating the presence of a preferred Aether reference frame through which the Earth is moving.

    • 摘要: 背景急性非静脉曲张性上消化道出血后存在再出血风险,且再出血会增加不良预后风险,但现阶段尚缺乏有效的预测手段.红细胞分布宽度、血红蛋白、胃泌素水平变化均与出血类疾病有关,推测可为临床完善相关机制、预测出血发生提供参考.目的探讨红细胞分布宽度(red cell distribution width,RDW)、血红蛋白(hemoglobin,Hb)、胃泌素(gastrin,GAS)与急性非静脉曲张性上消化道出血(acute nonvariceal upper gastrointestinal bleeding,ANVUGIB)患者Glasgow-Blatchford评分(Glasgow-Blatchford score,GBS)、AIMS65评分的关系及预测再出血的价值.方法选取2018-08/2021-02我院收治的122例ANVUGIB患者进行回顾性研究,根据发病后7 d是否发生再出血分为再出血组(n=31)、无再出血组(n=91),比较两组基线资料、RDW、Hb、GAS、GBS评分、AIMS65评分,采用Pearson分析各指标与GBS、AIMS65评分关系,采用多因素Logistic回归方程分析再出血的相关影响因素,采用受试者工作特征曲线(receiver operating characteristic,ROC)及ROC下面积(area under the curve,AUC)分析各指标预测再出血的价值,并比较各指标不同表达水平者再出血发生率.结果再出血组既往消化道出血患者占比高于无再出血组,RDW、GAS、GBS、AIMS65评分高于无再出血组,Hb低于无再出血组(P<0.05);RDW、GAS与GBS、AIMS65评分呈正相关,Hb与GBS、AIMS65评分呈负相关(P<0.05);多因素Logistic回归方程分析显示,将既往消化道出血、GBS、AIMS65评分控制后,RDW、Hb、GAS仍是再出血的相关影响因素(P<0.05);RDW、Hb联合GAS预测再出血的AUC(0.850)大于RDW(0.721)、Hb(0.721)、GAS(0.806);RDW、GAS高水平者再出血率高于低水平者,Hb高水平者再出血率低于低水平者(P<0.05).结论RDW、Hb、GAS与ANVUGIB患者病情危险度和再出血风险有关,联合检测可作为评估病情危险度及预测再出血的一个可靠方案,为临床治疗提供参考信息.

    • 摘要: Research on the so-called “pyramid power” began in the late 1930s. However, in general, pyramid power has been regarded as having no scientific basis, so there are very few systematic papers on pyramid power other than our academic research papers. Since October 2007, we have been conducting research to experimentally elucidate the unexplained phenomenon of a pyramid by using a pyramidal structure (PS). There have been two main types of experiments: (i) an experiment to detect the pyramid effects that appear due to the potential power (pyramid power) that the PS inherently has;and (ii) an experiment to detect the pyramid effects that appear when a test subject meditates inside the PS. To detect the pyramid effects, biosensors with evenly cut cucumber fruits, Cucumis sativus, were used. As a result of analyzing the concentration of volatile components emitted from the biosensors, we demonstrated the existence of pyramid power near the PS apex and discovered that the PS has the function of converting the unexplained energy of the meditator test subject. The research results so far have been reported as eleven original papers, three comprehensive reports, and one book chapter. We reported the phenomenon of the entanglement between biosensors in parts IV and V of the paper series, “Potential Power of the Pyramidal Structure”. Furthermore, we clarified that the influence of the entanglement is included in the psi index Ψ, which is an index of the magnitude of the pyramid effects. The purpose of the present paper was to separate and analyze the psi index Ψ into the effect of the potential power of the PS and the effect of the entanglement between biosensors (we have named this as the Bio-Entanglement). To do this, we placed biosensors at the PS apex in two layers. The value of the pyramid effect on the biosensors in the upper layer was always larger than that in the lower layer. We found that this was mainly due to the potential power of the PS. We also found that the factor that caused the pyramid effect to change seasonally was mainly the effect of the Bio-Entanglement. In short, we determined that the potential power of the PS, and the Bio-Entanglement had different effects on the biosensors. We were also able to propose a model that could qualitatively explain the analysis results of the psi index Ψ. We expect that our research results will be widely accepted in the future and will become the foundation for a new research field in science, with a wide range of applications.

    • 摘要: Vegetables and fruits are known to have long-lasting biological reactions even after harvesting. Volatile components may be released as a biological response to stimulation or injury. We measured the concentrations of volatiles released from the cut surfaces of cucumbers after their harvest and analyzed the relationship between the time the cucumbers were cut and gas concentrations. The results showed that gas concentrations indicate a circadian rhythm. We previously reported that the circadian rhythm of gas concentrations was 6 hours per cycle in the summer, i.e., from the vernal equinox to the autumnal equinox, and 24 hours per cycle in the winter, i.e., from the autumn equinox to the vernal equinox. We analyzed the gas concentrations emitted from cucumber sections in more detail in this paper and found that the circadian rhythms differ among winter, spring, summer, and autumn seasons. We found that one cycle of the circadian rhythm was 8 hours in winter, 6 hours in spring, 24 hours in summer, and a mixed cycle of 24 and 12 hours in autumn.

    • 摘要: CH_(4) storage associated with adsorbed natural gas(ANG)technology is an issue attracting great concern.Following the Advanced Research Project Agency-Energy(ARPA-E)targeted deliverable capacity of 315 cm^(3)·cm^(-3)(STP),hundreds of thousands of materials have been experimentally or theoretically evaluated,while the best results still show a 35% gap from the target.Moreover,recent theoretical research reveals that the target is beyond the possibility that real materials can be designed.To get rid of the awkward situation,we make attempts on investigating the CH_(4) delivery performance under other operation conditions.Methods of raising the discharge temperature(to infinite high)or elevating the storage pressure(to 25 MPa)have been proved to show limited effectiveness.In this work,it is found that the ARPA-E target can be achieved by using a decreasing storage temperature strategy.By taking 280 CoRE(computation-ready,experimental)COFs(covalent organic frameworks)as ANG materials,when reduce the storage temperature to 190.6 K,the highest deliverable capacity can reach 392 cm^(3)·cm^(-3)(STP),and 16.1% CoRE COFs can surpass the target.The target is also achievable when storage at 220 K.Structure performance relationships study shows strong correlation between deliverable capacity and void fraction.Hence,120 hypothetical COFs are generated to ascertain the optimum void fraction.In addition,the performance of 2D-COFs can be greatly enhanced by increasing the interlayer spacings,e.g.CH_(4) deliverable capacity(storage at 190.6 K)of ATFG-COF can be improved from 239 to 411 cm^(3)·cm^(-3)(STP)when interlayer spacing is enlarged to 1.65 nm.
