Advanced numerical studies of the neutralized drift compression of intense ion beam pulses

Physical Review Special Topics. Accelerators and Beams, 2007
Longitudinal bunch compression of intense ion beams for warm dense matter and heavy ion fusion applications occurs by imposing an axial velocity tilt onto an ion beam across the acceleration gap of a linear induction accelerator, and subsequently ...

Physical Characteristics of the Compressibility of Saturated Cohesive Soil

IOP Conference Series: Earth and Environmental Science, 2020
Abstract Water content and liquid limit are basic physical properties in saturated cohesive soils. Through the statistical analysis of compression index and these two physical properties, trends showed that compression index increases with increasing water content and liquid limit.

Retrotransposon Expression Is Upregulated in Adulthood and Suppressed during Regeneration of the Limb in the Axolotl (Ambystoma mexicanum)

Advanced Biology, EarlyView.
The axolotl's remarkable regenerative abilities decline with age, the causes may include the numerous repetitive elements within its genome. This study uncovers how Ty3 retrotransposons and coexpression networks involving muscle and immune pathways respond to aging and regeneration, suggesting that transposons respond to physiological shifts and may ...

Induced tooth movement: standardization of terms to describe the effects of forces on the periodontal ligament: compression/Traction instead of Pressure/Tension

Dental Press Journal of Orthodontics, 2012
There is no reason for Dentistry to use different terms for phenomena defined in Physics, the specific field in which concepts associated with forces are established and adapted. In place of pressure/tension, the compression/traction pair should be used.

Microphysiological Glomerular Filtration Barriers: Current Insights, Innovations, and Future Applications

Advanced Biology, EarlyView.
The glomerular filtration barrier (GFB) is the first step of blood filtration by the kidneys. The concerning increase of kidney diseases makes the development of new models essential. In this context, microphysiological glomerular filtration barriers focus on closely reproducing the physiological architecture of the in vivo GFB: podocytes, glomerular ...

Fast Faraday cup to measure neutralized drift compression in intense ion charge bunches

Physical Review Special Topics. Accelerators and Beams, 2006
Heavy ion drivers for heavy ion fusion and high energy density physics applications use space-charge-dominated ion beams which must undergo longitudinal bunch compression in order to meet the requisite beam intensities desired at the target.

Infrared attosecond field transients and UV to IR few-femtosecond pulses generated by high-energy soliton self-compression

Physical Review Research, 2020
Infrared femtosecond laser pulses are important tools both in strong-field physics, driving x-ray high-harmonic generation, and as the basis for widely tunable, if inefficient, ultrafast sources in the visible and ultraviolet. Although anomalous material

Collaborative Compressive Detection With Physical Layer Secrecy Constraints

IEEE Transactions on Signal Processing, 2017
This paper considers the problem of detecting a high dimensional signal (not necessarily sparse) based on compressed measurements with physical layer secrecy guarantees. First, we propose a collaborative compressive detection (CCD) framework to compensate for the performance loss due to compression with a single sensor.
