Imagine the World, New Insight into Creation, Gravity and Evolution*

引用

Journal of Modern Physics 2023年第4期14卷 461-500页

作者： Jarl-Thure eriksson Åbo Akademi University Åbo Finland

Since the publication of Einstein’s theory of general relativity, a variety of interpretations have been suggested. In 1937, Paul Dirac presented his Large Number Hypothesis (LNH) based on the large difference between gravitational and electromagnetic forces. As a consequence, the energy is proportional to the radius squared and the gravitational constant is inversely proportional to the radius of the universe. The energy increases during expansion, Dirac used the term “additive creation”. The objective is to prove the validity of Dirac’s claims. A new theory, CBU (Continuously Breeding Universe), has been developed. The universe is considered a black hole originating from the single fluctuation of a positron-electron pair. The expansion is driven by the formation of new pairs. The negative gravitational potential energy balances the increase in matter energy. Due to G ~ 1/r, the Planck length and Planck time tP depend on the curvature of space. The Schrödinger solution of an initial positron-electron fluctuation contains a parameter equal to the Planck length. The CBU theory postulates that the primordial universe undergoes a transition from a black hole to a photon-filled universe. After the transition, one half of the energy is bound to numerous “small” black holes, the seeds for galaxies, while the other half propagates as CMB (Cosmic Microwave Background) radiation. The CMB photons are due to e+ -e- annihilations. Characteristically, the CMB photons are pairwise entangled, the radiation loses wave energy but compensates by increasing the photon numbers. According to a new model for black holes, a continuous inflow of matter prevents the black holes from becoming singularities. An energy gap between the event horizon and the inner photon sphere is the source of real matter from a QED vacuum foam. There is evidence that all stellar matter originates from a proton-antiproton outflow from the galaxy central black hole.

Descemet-membrane endothelial keratoplasty in patients with retinal comorbidity -a prospective cohort study

引用

International Journal of Ophthalmology(English edition) 2016年第3期9卷 390-394页

作者： kristina Spaniol Christoph Holtmann Jan-Hendrik Schwinde Sophia Deffaa Rainer Guthoff Gerd Geerling University Eye Hospital Dusseldorf Moorenstraβe 5Dusseldorf 40225 Germany

AIM： To investigate indications, surgical challenges, and outcome of Descemet -membrane endothelial keratoplasty （DMEK） in patients with retinal comorbidities （RC）. METHODS： In a prospective cohort study, 8 eyes of 8 DMEK-patients with known RC were compared to 38 eyes of 38 DMEK-patients without RC. The duration of surgery, the degree of difficulty graded by the surgeon, and the complications through DMEK-surgery were analyzed for each patient. The best-corrected visual acuity （BCVA）, the endothelial cell count, the intraocular pressure, and the subjective satisfaction was evaluated after a 6-month follow-up. Data were compared applying the non-parametric Wilcoxon-, Chi-square- and Fisher＇s-exact-test with P≤ 0. 05 as level of significance. RESULTS： RC-patients had dry age-related macular degeneration （n=4） or history of pars-plana vitrectomy （n=4）. The main indication for DMEK was pain due to bullous keratopathy for the RC-patlents （n=7, 88%） and visual impairment due to Fuchs endothelial keratoplasty for the non-RC-patients （n=33, 87% ）. The BCVA increased for both groups （P=0.01, P〈0.001） and all corneas cleared. For the RC-patients, the subjective satisfaction improved significantly （P=0.02）. Oil-filling and missing support of the vitreous body complicated surgery in vitrectomized eyes. CONCLUSION： DMEK is a favorable technique to treat endothelial disorders even if patients suffer from a retinal comorbidity. By enhancing the corneal clarity, it enables retinal examination or intraocular surgery and increases the patients satisfaction. However, in vitrectomized or silicone-oil filled eyes, the duration of surgery and degree of complexity are increased. An experienced surgeon should perform DMEK in these patients. Clinical trial registration number： DRKS00007566.

Perioperative liver and spleen elastography in patients without chronic liver disease

World Journal of Gastrointestinal Surgery 2018年第2期10卷 21-27页

AIM To investigate changes in hepatic and splenic stiffness in patients without chronic liver disease during liver resection for hepatic *** Patients scheduled for liver resection for hepatic tumors were considered for enrollment. Tissue stiffness measurements on liver and spleen were conducted before and two days after liver resection using point shear-wave elastography. Histological analysis of the resected liver specimen was conducted in all patients and patients with marked liver fibrosis were excluded from further study analysis. Patients were divided into groups depending on size of resection and whether they had received preoperative chemotherapy or not. The relation between tissue stiffness and postoperative biochemistry was investigated. RESULTS Results are presented as median(interquartile range). 35 patients were included. The liver stiffness increased in patients undergoing a major resection from 1.41(1.24-1.63) m/s to 2.20(1.72-2.44) m/s(P = 0.001). No change in liver stiffness in patients undergoing a minor resection was found [1.31(1.15-1.52) m/s vs 1.37(1.12-1.77) m/s, P = 0.438]. A major resection resulted in a 16%(7%-33%) increase in spleen stiffness, more(P = 0.047) than after a minor resection [2(-1-13) %]. Patients who underwent preoperative chemotherapy(n = 20) did not differ from others in preoperative right liver lobe [1.31(1.16-1.50) vs 1.38(1.12-1.56) m/s, P = 0.569] or spleen [2.79(2.33-3.11) vs 2.71(2.37-2.86) m/s, P = 0.515] stiffness. Remnant liver stiffness on the second postoperative day did not show strong correlations with maximum postoperative increase in bilirubin(R^2 = 0.154, Pearson's r = 0.392, P = 0.032) and international normalized ratio(R^2 = 0.285, Pearson's r = 0.534, P = 0.003). CONCLUSION Liver and spleen stiffness increase after a major liver resection for hepatic tumors in patients without chronic liver disease.

The Relation between Music and Philosophy： Three Retrospects/Perspectives

引用

Journal of Philosophy Study 2017年第10期7卷 553-561页

作者： kristina Yapova Bulgarian Academy of Sciences

Having for its object the relation between music and philosophy, the present article aims, on the one hand, to seek out the philosophical resources contained in foundational texts in terms of musical knowledge, and, on the other, to outline the musical resources enriching philosophical knowledge. With this end in view, three retrospects/perspectives are examined which can be traced throughout the history of the music-philosophy relation. The first looks back at the two basic words referring to music in Greek philosophy （armonia and musikg） in order to find out how the human ability for musical knowledge can be activated when these two are brought together. The second focuses on what lies at the heart of music, namely the thing which can be defined as the tone-ness of the tone. The third explores the art-and-science content of music, which allows for a further perspective to be drawn forth--a perspective on musical knowledge proceeding from, though at the same time remaining with music as a mode of human existence.
