Pulmonary artery catheter monitoring versus arterial waveform-based monitoring during liver transplantation: a retrospective cohort study

open access: yesScientific Reports, 2023
Although pulmonary artery catheter (PAC) has been used during liver transplantation surgery, the usefulness of PAC has rarely been investigated. We evaluated whether the use of PAC is associated with better clinical outcomes compared to arterial waveform-

Pulmonary artery catheter placement in patients with a history of tricuspid ring annuloplasty, with pulmonary stenosis, and with the transvenous pacemaker leads: is it difficult?

open access: yesJA Clinical Reports, 2018
Purpose Previous case reports suggested that the presence of obstruction in the passage of the pulmonary artery catheter (PAC) may hinder its placement.

The gravitational-wave memory from eccentric binaries [PDF]

open access: yes, 2011
The nonlinear gravitational-wave memory causes a time-varying but nonoscillatory correction to the gravitational-wave polarizations. It arises from gravitational waves that are sourced by gravitational waves.

Full-waveform inversion in three-dimensional PML-truncated elastic media

open access: yes, 2015
We are concerned with high-fidelity subsurface imaging of the soil, which commonly arises in geotechnical site characterization and geophysical explorations.

Single-pulse and multipulse longitudinal phase space and temperature measurements of an intense ion beam

open access: yesPhysical Review Special Topics. Accelerators and Beams, 2012
Longitudinal phase space and temperature measurements were conducted on a 2–3  μs long, singly charged K^{+} ion bunch with an ion energy of ∼0.3  MeV and current of 30 mA. The principal objective of these experiments was to measure the longitudinal beam

Gravitational wave emission from binary supermassive black holes

open access: yes, 2013
Massive black hole binaries (MBHBs) are unavoidable outcomes of the hierarchical structure formation process, and according to the theory of general relativity are expected to be the loudest gravitational wave (GW) sources in the Universe.

Slight Truncation Changes in Iron Oxide Nanocubes Strongly Affect Their Magnetic Properties

open access: yesAdvanced Functional Materials, EarlyView.
Subtle variations in nanoparticle morphology can lead to significant changes in functional properties. An automated shape‐fitting method captures minor differences in corner truncation between iron oxide nanocubes of similar sizes synthesized under identical conditions, revealing pronounced disparities in their magnetic and hyperthermia behavior ...

Concussion case classification based on brain strain waveforms using dynamic time warping and cluster analysis

open access: yesJournal of Biomechanical Science and Engineering
In sports, concussion prevention measures require the development of concussion evaluation criteria for improved head protective gear or early intervention through impact measurement in the field.

Use of waveform lidar and hyperspectral sensors to assess selected spatial and structural patterns associated with recent and repeat disturbance and the abundance of sugar maple (Acer saccharum Marsh.) in a temperate mixed hardwood and conifer forest. [PDF]

open access: yes, 2011
Waveform lidar imagery was acquired on September 26, 1999 over the Bartlett Experimental Forest (BEF) in New Hampshire (USA) using NASA\u27s Laser Vegetation Imaging Sensor (LVIS).
