Measuring Low Frequency Tilts
A borehole tiltmeter with a sensitivity of a few nanoradians is described. It is composed of two orthogonal horizontal pendulums with free periods of 1 s. The pendulums are insensitive to barometric pressure fluctuations, and the measured temperature coefficient is less than 30 nrad/°C. The range of the pendulums is about ±5 μ rad, and their response is linear within 1% and stable over several ...
متن کاملTrisomy 21 tilts the balance.
Approximately 5% of children with Down syndrome (DS) are born with a unique transient clonal megakariyo-erythroblastic proliferation disorder often called transient myeloproliferative disorder (TMD). Spontaneous recovery usually occurs within up to several months. However, about one-fifth of these patients will develop full-blown acute leukemia with biphenotypic megakaryocyticerythroid features...

fle findings as far north as Gotland (a Baltic island off the southeast Swedish coast) further suggest a close link to environmental change (Wedén et al. 2005). Assessment of high-resolution climatic data (Mitchell and Jones 2005) revealed spatial differences of ~0.5 ̊C between mean temperatures in Burgundy and our study site, which corresponded with temporal changes in mean temperatures observe...
متن کاملTilts in Strong Ground Motion
Most instruments used in seismological practice to record ground motion are pendulum seismographs, velocigraphs, or accelerographs. In most cases it is assumed that seismic instruments are only sensitive to the translational motion of the instrument’s base. In this study the full equation of pendulum motion, including the inputs of rotations and tilts, is considered. It is shown that tilting th...
متن کاملProbabilistic Cluster Unfoldings
This article introduces probabilistic cluster branching processes, a probabilistic unfolding semantics for untimed Petri nets, with no structural or safety assumptions, giving probability measures for concurrent runs. The unfolding is constructed by local choices on each cluster (conflict closed subnet), while the authorization for cluster actions is governed by a stochastic trace, the policy, ...
