Sideband Cooling Micromechanical Motion to the Quantum Ground State

open access: yes, 2011
The advent of laser cooling techniques revolutionized the study of many atomic-scale systems. This has fueled progress towards quantum computers by preparing trapped ions in their motional ground state, and generating new states of matter by achieving ...

Estimation of strong ground motions from hypothetical earthquakes on the Cascadia subduction zone, Pacific Northwest [PDF]

open access: yes, 1986
Strong ground motions are estimated for the Pacific Northwest assuming that large shallow subduction earthquakes, similar to those experienced in southern Chile, southwestern Japan, and Colombia, may also occur on the Cascadia subduction zone.

The newfound relationship between extrachromosomal DNAs and excised signal circles

open access: yesFEBS Letters, EarlyView.
Extrachromosomal DNAs (ecDNAs) contribute to the progression of many human cancers. In addition, circular DNA by‐products of V(D)J recombination, excised signal circles (ESCs), have roles in cancer progression but have largely been overlooked. In this Review, we explore the roles of ecDNAs and ESCs in cancer development, and highlight why these ...

Strong Ground Motion Characteristics of the Saturated Loess Site

open access: yesShock and Vibration
Significant differences exist in the ground response of saturated and unsaturated deposits to earthquakes, but few relevant studies exist on strong ground motion in saturated loess.

Near-Field Ground Motion Modal versus Wave Propagation Analysis

open access: yesShock and Vibration, 2010
The response spectrum generally provides a good estimate of the global displacement and acceleration demand of far-field ground motion on a structure.

The Great 1822 Aleppo Earthquake: New historical sources and strong ground motion simulation

open access: yesGeofísica Internacional, 2022
El terremoto de 1822 fue devastador y se considera uno de los eventos relativamente recientes que azotaron el noroeste de Siria y las áreas cercanas del centro-sur de Turquía, es decir, en la unión del sistema de fallas del Mar Muerto con el sistema de ...

Multi-frame scene-flow estimation using a patch model and smooth motion prior [PDF]

open access: yes, 2010
This paper addresses the problem of estimating the dense 3D motion of a scene over several frames using a set of calibrated cameras. Most current 3D motion estimation techniques are limited to estimating the motion over a single frame, unless a strong ...

Sequence determinants of RNA G‐quadruplex unfolding by Arg‐rich regions

open access: yesFEBS Letters, EarlyView.
We show that Arg‐rich peptides selectively unfold RNA G‐quadruplexes, but not RNA stem‐loops or DNA/RNA duplexes. This length‐dependent activity is inhibited by acidic residues and is conserved among SR and SR‐related proteins (SRSF1, SRSF3, SRSF9, U1‐70K, and U2AF1).

A procedure to select ground-motion time histories for deterministic seismic hazard analysis from the Next Generation Attenuation (NGA) database [PDF]

open access: yesNatural Hazards and Earth System Sciences, 2017
In performance-based seismic design, ground-motion time histories are needed for analyzing dynamic responses of nonlinear structural systems. However, the number of ground-motion data at design level is often limited.

Predominant Frequency in Near-Field Strong Ground Motion by Analysis of Displacement Response Spectra

open access: yesBuildings, 2023
A literature review on the spectral content of seismic ground motion indicates that a clear predominant frequency in earthquakes is very difficult to define.
