Physical, Epistemological and Metaphysical Perspectives on Quantum Theory： Constructed Experience？

Journal of Philosophy Study 2017年第12期7卷 621-633页

作者： Zulena dos S. Silva pedro ⅱ college

This paper will present questions from three perspectives about Quantum Mechanics （QM）： physics, epistemological, and metaphysical. The quantum phenomena do not fit with the parameters of classical physics, so a daily intuition on macroscopic world is dispensable when it is the quantum object investigated. This physical domain induces a new thinking, which requires also new concepts to describe such object. The QM is disturbing and stimulates epistemological reflections, as the issues of access about what is known; and metaphysical theme are not to be left behind with regard to QM： What would the quantum object to？ What is apprehended when this object is perceived, once considered the disturbing characteristics that constitute its physical description： interference and non-separability？ What is its nature？ This paper focuses briefly on the analysis of B. d＇Espagnat in Veiled Reality, which would represent the physical perspective of QT; for epistemological questions, one will resort to the Kantian conception of knowledge; and with regard to the metaphysical perspective, we will rely on an article by Professor J. B. Arenhart. It is necessary to note that the question that pervades in this paper is about if the experience in QM is built. Thus, we will try to seek clarity on the philosophical issues through QT, regarding the problems about the possibility of knowledge of the quantum object and its nature, and whether experience in this case is built. But furthermore, the QM instigates us to think whether metaphysics proceeds on the investigation of nature when it comes to the QM. And such a question is more than to have as problem as the scope of the description of physical data, but rather whether it makes sense or whether metaphysical research is pertinent to the QM.

Asian Herpetological Research 2021年第1期12卷 76-87页

The Mt. Kitanglad Range is one of the country’s important key biodiversity sites;however, information about anuran diversity in this protected area remains depauperate. Herein we provided accounts of anuran species from high-elevation forests, in three sites of the western slope of Mt. Kitanglad range. The combined belt-transect sampling and microha bitat searches accounted for 13 species representing five families. The most represented family was Rhacophoridae with five representative species of the genus Philautus. Twelve out of the 13 species documented in the current survey are endemic. Four previously unaccounted species(Pelophr yne brevipes, Pulchrana grandocula, Sanguirana mearnsi, and Philautus surrufus) were added and brought the total anurans known from Mt. Kitanglad to 26 species. Most of the species were also recorded in forested sites, suggestive of their lesser affinity to non-forested ecosystems. The additional species detected during our survey may also imply that full understanding of anuran diversity of Mt. Kitanglad remains far from complete.

Potential Autonomous Selfing in Gesneria citrina (Gesneriaceae),a Specialized Hummingbird Pollinated Species with Variable Expression of Herkogamy

Journal of Integrative Plant Biology 2009年第10期51卷 973-978页

Fenster Xishuangbanna Tropical Botanical Garden the Chinese Academy of Sciences Mengla 666303 China Department of Biology University of Maryland College Park MD 20742 USA Herbario de la Universidad de Costa Rica Escuela de Biologia Ciudad Universitaria Rodrigo Facio San Pedro San Jose Costa Rica

Species with mixed mating systems often demonstrate variable expression of breeding system characteristics and thus represent the opportunity to understand the factors and mechanisms that promote both outcrossed and selfed seed production. Here, we investigate variation in levels of herkogamy （variation in stigma-anther separation distance） in a Puerto Rican population of hummingbird pollinated Gesneria citrina Urban. There is significant variation in herkogamy levels among individuals of this species and stigma-anther separation is negatively associated with the ability to set fruits and seeds in the absence of pollinators. The variation in levels of herkogamy may represent a mechanism to ensure the production of some self-fertilized progeny in the absence of hummingbird pollinators. We also describe a novel breeding system in G. citrina, where stamens elongate over time to reach stigma height, but stamen elongation is accelerated by pollination. These results suggest that once the flowers are pollinated, stamen elongation may favor increased pollen removal and siring success, while the reduction in stigma-anther distance no longer imposes the risk of interference between male and female functions. We discuss our findings of breeding system variation in the context of pollination system evolution in an island setting （Antillean islands）.

An efficient source wavefield reconstruction scheme using single boundary layer values for the spectral element method

In the adjoint-state method, the forward-propagated source wavefield and the backward-propagated receiver wavefield must be available simultaneously either for seismic imaging in migration or for gradient calculation in inversion. A feasible way to avoid the excessive storage demand is to reconstruct the source wavefield backward in time by storing the entire history of the wavefield in perfectly matched layers. In this paper, we make full use of the elementwise global property of the Laplace operator of the spectral element method (SEM) and propose an efficient source wavefield reconstruction method at the cost of storing the wavefield history only at single boundary layer nodes. Numerical experiments indicate that the accuracy of the proposed method is identical to that of the conventional method and is independent of the order of the Lagrange polynomials, the element type, and the temporal discretization method. In contrast, the memory-saving ratios of the conventional method versus our method is at least N when using either quadrilateral or hexahedron elements, respectively, where N is the order of the Lagrange polynomials used in the SEM. A higher memorysaving ratio is achieved with triangular elements versus quadrilaterals. The new method is applied to reverse time migration by considering the Marmousi model as a benchmark. Numerical results demonstrate that the method is able to provide the same result as the conventional method but with about 1/25 times lower storage demand. With the proposed wavefield reconstruction method, the storage demand is dramatically reduced;therefore, in-core memory storage is feasible even for large-scale three-dimensional adjoint inversion problems.
