Investigating the impact of selfcare stress reduction strategies on cortisol levels
No full textIt has been shown that behavioral therapy has effects on stress and also cortisol levels. This study investigated the impact of self-care stress reduction strategies on the cortisol levels of 59 urine samples. Stress behavior was evaluated by using written responses (questionnaire). Results indicated that transcendental meditation was statistically associated with the lowering of cortisol levels. Meditation can relax the mind, leading to a reduction in stress. From this study, stress and cortisol levels do have a direct correlation with one another. The data from this small pilot study raise the question of its utility as a stress marker in cardiac rehabilitation.</p
The spiral wave trajectory motion of particles is the only reason for the establishment of the Poincare regression theorem (Background radiation is not evidence of the big bang of the cosmic singularity)
Get PDFIn short, an isolated and limited system will return to a state very close to the initial state in the long-term evolution process. For example, in a container, gas particles rotate in chaos and return to their initial position after a period of time. I have proved that everything is a spiral wave track (path) and has the property of wave: v = Fλ ; λ= uT. It is proved that any finite object (particle) has a common period: the nearest distance and the farthest distance. Such as the earth and the moon; Earth and the sun; The three bodies of the earth, the moon and the sun, and the comet and the earth all meet periodically. Particles also have this property. The principle is due to the periodicity of the spiral of an object.The Poincare regression theorem is proved by the spiral periodic wave pattern of the object.Mathematical classification code: 70F20;70F45;03D55;76Y99; 81V25; 37A55 </p
Research of superluminal phenomena revealed the essence and limitation of the relativity
Get PDFSuperluminal phenomena have been viewed as a contradiction to the Special Relativity, the in-variance principle of light velocity. This paper proposed the theory of the two kinds of epistemology and world, to explain the contradiction between the Special Relativity (SR) and Superluminal phenomena. It also discussed the influence of superluminal research on other science and technology, such as information science and superluminal communications.</p
A Poisson “Half-Summation” Formula
Get PDFA generalization of Poisson’s summation formula is derived – in a non-rigorous way – allowing evaluation of sums from 1 (or any finite integer) ∞ instead of the usual range -∞+∞. This is achieved in two ways, either by introducing a converging factor in a geometric series of exponential functions and letting it approach zero in a controlled way or by applying a Hilbert transform to the series. Several examples illustrate its usefulness in the evaluation of series and specific applications. </p
The results of a clinical and neurophysiological study of the effectiveness of Parkon spray in the treatment of Parkinson’s Disease (PD)
Get PDFFor more than 25 years, we have begun an experimental study of the physiological effect of micromolar concentrations of reactive oxygen species on the regulatory functions of the central nervous system. We found that these effects extend to the CNS centers and hormonal regulation of the hypothalamus and pituitary gland [1-4], as well as in the control of BBB permeability [5].</p
Therapeutic implications in patients with subacute thyroiditis in the SARS-CoV-2 era
Get PDFThe purpose of this mini-review is to provide the latest information on the treatment of Subacute Thyroiditis (SAT) in the era of Coronavirus Disease 2019 (COVID-19). It is well documented that SAT has a significant impact on the quality of life of the patients, so early and proper diagnosis and treatment are necessary in order to reduce or even eliminate the severity of symptoms, frequency of relapses, and permanent hypothyroidism. This requires a multidisciplinary management approach in order to meet patients’ special needs. The present mini-review aims to summarize recent research evidence regarding the therapeutic management of SAT with special recommendations for COVID-19-associated SAT. </p
Graphene oxide-based waveguides for enhanced self-phase modulation
Get PDFThe enhanced self-phase modulation (SPM) in silicon nitride (Si3N4) and silicon (Si) waveguides integrated with graphene oxide (GO) films is experimentally demonstrated. By using both picosecond and femtosecond optical pulses, we observe significant spectral broadening in the waveguides due to the high Kerr nonlinearity of GO films. The maximum broadening factors of up to ~3.4 and ~4.3 are achieved in GO-coated Si3N4 waveguides and GO-coated Si waveguides, respectively. The spectral broadening for femtosecond pulses is more significant than the picosecond pulses, which can be attributed to their relatively high peak power. These results show the strong potential of GO films for improving the Kerr nonlinearity of photonic devices. </p
Complex network reveals the spatiotemporal pattern of summer extreme precipitation in Eastern China
Get PDFIn this study, complex networks were constructed based on the synchronization of summer extreme precipitation events (SEPEs) in eastern China. Then, a detailed analysis of spatiotemporal patterns of SEPEs and the relationship between SEPEs in eastern China with the eastern Asian monsoon was presented. The results showed that (1) the event synchronization is low in the coastal region but high in the inland region; (2) the intensity of the monsoon varies at different phases of summer and the area and intensity of the monsoon's influence on the summer extreme rainfall events were different. In conclusion, this study provides valuable insights to reveal the influence of monsoon strength on SEPEs in different regions of China. </p
Convolutional modelling of epidemics
Get PDFTraditional deterministic modeling of epidemics is usually based on a linear system of differential equations in which compartment transitions are proportional to their population, implicitly assuming an exponential process for leaving a compartment as happens in radioactive decay. Nonetheless, this assumption is quite unrealistic since it permits a class transition such as the passage from illness to recovery that does not depend on the time an individual got infected. This trouble significantly affects the time evolution of epidemy computed by these models. This paper describes a new deterministic epidemic model in which transitions among different population classes are described by a convolutional law connecting the input and output fluxes of each class. The new model guarantees that class changes always take place according to a realistic timing, which is defined by the impulse response function of that transition, avoiding model output fluxes by the exponential decay typical of previous models. The model contains five population compartments and can take into consideration healthy carriers and recovered-to-susceptible transition. The paper provides a complete mathematical description of the convolutional model and presents three sets of simulations that show its performance. A comparison with predictions of the SIR model is given. Outcomes of simulation of the COVID-19 pandemic are discussed which predicts the truly observed time changes of the dynamic case-fatality rate. The new model foresees the possibility of successive epidemic waves as well as the asymptotic instauration of a quasi-stationary regime of lower infection circulation that prevents a definite stopping of the epidemy. We show the existence of a quadrature function that formally solves the system of equations of the convolutive and the SIR models and whose asymptotic limit roughly matches the epidemic basic reproduction number.</p
Co-beneficial relationship-based care for persons with dementia
Get PDFCo-beneficial relationship-based care has been proposed as a basic concept of dementia care to improve the social well-being of persons with dementia and those close to them, including family members and caregivers. The aim is to empower persons with dementia to manifest their innate altruism, which is intact until the end-of-life period. As dementia may change relationships even among family members, it is desirable for persons with dementia and those close to them to make efforts to maintain mutually beneficial relationships in their daily lives.</p
