Acoustic tomography of the atmospheric surface layer (ASL) is based on measurements of the travel times of sound propagation between sources and receivers which constitute a tomography array. Then, the temperature and wind velocity fields inside the tomographic volume or area are reconstructed using different inverse algorithms. Improved knowledge of these fields is important in many practical ...

Information about places is ubiquitous in the study of history, events occur, people live, and phenomena flourish in more or less identifiable locations. To a greater or lesser extent, all historians make use of geographical information. Potentially, there is a great potential for the use of Geographical Information Systems (GIS) in the discipline. However, GIS with origins in the earth science...

Little is known about the relative importance of environmental, biotic, historical, and spatial factors that influence invasive plant abundance, dominance, and distribution across landscapes. We identified factors that influence the abundance and dominance of Potentilla recta L. (sulfur cinquefoil) in bunchgrass grasslands of northeastern Oregon to better understand the conditions under which i...

Nearly 40 years ago, in the pages of this journal, Hubel and Wiesel provided the first description of receptive fields in the primary visual cortex of higher mammals. They defined two classes of cortical cells, "simple" and "complex", based on neural responses to simple visual stimuli. The notion of a hierarchy of receptive fields, where increasingly intricate receptive fields are constructed f...

The public considers sociopolitical revolutions and movements as phenomena that occur suddenly and unpredictably. Still, these phenomena carry historical content and stem from sophisticated sociopolitical, cultural, and economic factors in the view of political scientists. Such a view provides the context in which sociopolitical revolutions and movements are analyzed, not in a single cause, but...

Direct-current (DC) electric fields are present in all developing and regenerating animal tissues, yet their existence and potential impact on tissue repair and development are largely ignored. This is primarily due to ignorance of the phenomenon by most researchers, some technically poor early studies of the effects of applied fields on cells, and widespread misunderstanding of the fundamental...

Studying the communication patterns of scientists can give us insight into how science actually works. We argue that methodological differences between different scientific fields should lead to recognizable differences in how scientists in these fields use language to communicate with one another. This paper reports on a corpus-based study of peer-reviewed journal articles in paleontology and ...

Abstract. Antarctic ice velocity maps describe the flow dynamics of sheet and are one primary components used to estimate mass balance contribution global sea level changes. In comparison derived from recent satellite images monthly weekly time spans, historical maps, before 1990s, generally cover longer e.g., over 10 years, due scarce spatial temporal coverage earlier image data. We found over...

This essay focuses on the fields of architectural documentation and digital representation. We present a research paper concerning the development of an information system at the scale of architecture, taking into account the relationships that can be established between the representation of buildings (shape, dimension, state of conservation, hypothetical restitution) and heterogeneous informa...
