From Artifacts to Aggregations: Modeling Scientific Life Cycles on the Semantic Web [PDF]
, 2009 In the process of scientific research, many information objects are generated, all of which may remain valuable indefinitely. However, artifacts such as instrument data and associated calibration information may have little value in isolation; their ...

DEFINITION OF EARTHQUAKE FOCUS COORDINATES USING A COMBINED METHOD
Вестник Дагестанского государственного технического университета: Технические науки, 2017 Objectives. The aim of the study is to determine earthquake hypocentres with the simultaneous use of both the sphere and hyperboloid methods of calculation, providing minimal possible error due to the appropriate choice of seismic sensors.Method.

Distributed archive and single access system for accelerometric event data : a NERIES initiative [PDF]
, 2011 We developed a common access facility to homogeneously formatted accelerometric event data and to the corresponding sheet of ground motion parameters. This paper is focused on the description of the technical development of the accelerometric data server

Active Metamaterials with Tunable Shear Nonreciprocity and Nonlinear Dynamics
Advanced Science, EarlyView.Active gear‐based mechanical metamaterials enable simultaneous control of translational and torsional stiffnesses by 30–100×, break shear reciprocity under positive versus negative loads, broadly tune resonant frequencies, and offer programmable dynamic responses.

Redescription of the Triassic cynodont Cistecynodon parvus and reassessment of its phylogeny
The Anatomical Record, EarlyView.Abstract Cynodontia is an important subclade of Therapsida that first occurred in the late Permian. It includes extinct subclades which are the non‐mammaliaform cynodonts and Mammaliaformes, with the latter ultimately giving rise to crown mammals. The systematics of non‐mammaliaform cynodonts has been extensively studied and is relatively well‐resolved,

A Bayesian Framework for Estimating Seismic Wave Arrival Time [PDF]
, 2019 Because earthquakes have a large impact on human society, statistical methods for better studying earthquakes are required. One characteristic of earthquakes is the arrival time of seismic waves at a seismic signal sensor.

Archaeological Prospection, EarlyView.ABSTRACT Ancient Olympia was one of the most important sanctuaries and the venue for the Olympic Games in Greek and Roman times. Its remains are located in the Olympia Terrace (Peloponnese, Greece) at the present‐day confluence of the rivers Alpheios and Kladeos at the base of Mount Kronos.
