We present a spectral theory of uniform hypergraphs that closely parallels Spectral Graph Theory. A number of recent developments building upon classical work has led to a rich understanding of “symmetric hyperdeterminants” of hypermatrices, a.k.a. multidimensional arrays. Symmetric hyperdeterminants share many properties with determinants, but the context of multilinear algebra is substantiall...

Seismic images and the geologic information they provide contribute significantly to our understanding of the earth’s subsurface. In this thesis, I focus on methods relevant for constructing and interpreting seismic images, including methods for velocity estimation, seismic imaging, and interpretation, which together address key aspects of reflection seismic data processing. Specifically, I pro...

SUMMARY In this paper we investigate the effects of different sampling operators on the performance of sparse reconstruction methods. The common paradigm in seismic data processing is to favor regular sampling. We will show, however, that regular sampling often hampers our data recovery efforts. Random sampling, on the other hand, can lead to algorithms where the reconstruction is almost perfec...

We have proposed that haptic activation of the shape-selective lateral occipital complex (LOC) reflects a model of multisensory object representation in which the role of visual imagery is modulated by object familiarity. Supporting this, a previous functional magnetic resonance imaging (fMRI) study from our laboratory used inter-task correlations of blood oxygenation level-dependent (BOLD) sig...

Ground motion estimation for a site (34.01 o N, 71.45 o E) located in the Peshawar in terms of Peak Ground Acceleration (PGA) values is conducted. It is carried out with deterministic seismic hazard analysis approach using faults sources within a radius of one hundred kilometers around site. The results of this study indicate that the Main Boundary Thrust located at a distance of twenty nine (2...

The February 21, 2008, Wells earthquake (MW=6.0) occurred in a region of northeastern Nevada where the seismicity has historically been low relative to western Nevada. In a region of area of approximately10 5 km 2 of northeastern Nevada, based rates of smaller earthquakes in the region prior to 2008, earthquakes of MW=6.0 or larger are expected with a rate of about 0.01 per year. The probabilit...

В связи с появлением новых данных о существенной вариабельности, полученных для территории РСО-Алания интегральных (кумулятивных) оценок макросейсмической интенсивности сотрясений разных по сейсмическим свойствам грунтов, этого же района рассмотрены аналогичные количественные оценки других важных научной и практической точек зрения характеристик сейсмических воздействий – спектров колебаний «мя...

Abstract We present the positions, proper motions, and near-infrared photometry for 966 known objects with spectral types later than M that were observed as part of UKIRT Hemisphere Survey (UHS). augment astrometry from UHS information Gaia DR3, Pan-STARRS DR2, CatWISE 2020 to produce a database homogeneous this sample. The multi-epoch survey strategy allows us determine motions most sources, m...

The performance of a large number critical infrastructure systems needs to be periodically re-evaluated. This is especially so when such are located in seismic areas and subjected ageing effects. Seismic re-evaluations typically performed using numerical response history analyses based on geotechnical model the hazard-consistent ground motions. We depart from Viadotto Italia (the tallest multi-...
