As a first step towards practical use and as a proof of concept we used an existing system to image the interior of a reference reinforced 600 kg concrete block. Even with a yet not optimized setup for this kind of investigation, the muon imaging results are at least of similar quality ...
摘要原文 The concept of plate tectonics, introducednearly twenty years ago,unified many fields of earth scienceby providing a global framework forlarge-scale geological processes.Seismology played an important rolein the formulation of this theory bysupplying maps of global seismicity,delineating plate bo...
3, implying a considerable complement of light elements. Core compositions based on seismic and bulk geophysical constraints, however, require larger quantities of the volatile elements hydrogen, carbon and sulfur than those that were
It is one of the more elaborate ML algorithms –a statical model that analyzes the features of data and groups it accordingly. [Source] Hidden Markov Model is a variation of the simple Markov chain that includes observations over the state of data, which adds another perspective on the data ...
Moderate-to-profound sensorineural hearing loss in humans is treatable by electrically stimulating the auditory nerve (AN) with a cochlear implant (CI). In the cochlea, the modiolus presents a porous bony interface between the CI electrode and the AN. Ne
The 17th Study of the Earth's Deep Interior (SEDI) meeting was held in Zurich, Switzerland, from 11th July to 15th July 2022. The SEDI group is a Union Committee of the International Union of Geology and Geophysics dedicated to the Study of the Earth's Deep Interior and, by ex...
scales to allow detailed reconstruction of atmospheric motions in evolved stars. A recently established tomographic method is an ideal technique for this purpose. It must be stated right away that the word “tomography” is used here with a meaning close to its etymological roots (“slice, ...
All these arguments are very nearly but not exactly linear in t, meaning that the periods are very slowly varying with time. The periods used to identify them are the values pertaining to J2000. The periods of the planets, which relate to the arguments λi, (i = 1, 2, …, 8) ...
When analyzed with commercial software that is used clinically, our model generated images yielded accurate quantities of fat, lean, and bone. Our work highlights the strong relationship between exterior body shape and interior composition. Moreover, it suggests that with enhanced accuracy, such ...
4and to infer the interior structure of Mars at all scales5. First results from the analysis of the SEIS data provide new information on the large-scale internal structure, physical properties, and tectonic activity of Mars3,6. Seismic studies of the shallow subsurface around the InSight ...
