Associations of Infant Feeding and Timing of Weight Gain and Linear Growth during Early Life with Childhood Blood Pressure: Findings from a Prospective Population Based Cohort Study.

PLoS ONE, 2016
ObjectiveSmall birth size and rapid postnatal growth have been associated with higher future blood pressure. The timing of these effects, the relative importance of weight gain and linear growth and the role of infant feeding need to be clarified ...

Optical signature of the pressure-induced dimerization in the honeycomb iridate $\alpha$-Li$_2$IrO$_3$ [PDF]

, 2019
We studied the effect of external pressure on the electrodynamic properties of $\alpha$-Li$_2$IrO$_3$ single crystals in the frequency range of the phonon modes and the Ir $d$-$d$ transitions.

Sound Pressure Level Gain in an Acoustic Metamaterial Cavity [PDF]

Scientific Reports, 2014
The inherent attenuation of a homogeneous viscous medium limits radiation propagation, thereby restricting the use of many high-frequency acoustic devices to only short-range applications. Here, we design and experimentally demonstrate an acoustic metamaterial localization cavity which is used for sound pressure level (SPL) gain using double coiled up ...

Building a Taxonomy to Understand Health Care Worker’s Response to Workplace ‘Pressure’ in Complex, Volatile and Emergency Situations

Inquiry: The Journal of Health Care Organization, Provision, and Financing, 2021
This research aims to better understand performance under pressure as experienced by health and emergency staff in the workplace. Three basic questions underpin the work: (1) how do health and emergency workers experience and make sense of the ‘pressures’

Dual contribution to amplification in the mammalian inner ear

, 2010
The inner ear achieves a wide dynamic range of responsiveness by mechanically amplifying weak sounds. The enormous mechanical gain reported for the mammalian cochlea, which exceeds a factor of 4,000, poses a challenge for theory.

Electron density diagnostics in atmospheric pressure radio frequency dielectric barrier discharge and discharge with bare electrode [PDF]

, 2019
Electron densities in two types of atmospheric pressure radio frequency plasma sources: dielectric barrier discharge (DBD) and discharge with bare electrode (DBE) are investigated by analysis of Stark broadening of Hydrogen Balmer (Hβ) lines.

Performance Analysis of Wave Rotor Combustor Integration into Baseline Engines: A Comparative Study of Pressure-Gain and Work Cycles

Energies
This study presents two concepts for integrating a wave rotor combustor (WRC) into a baseline engine: the wave rotor pressure-gain cycle (WRPGC) and the wave rotor work cycle (WRWC).

Infant Weight Gain and Later Blood Pressure [PDF]

Circulation, 2002
To the Editor: Recently, Law et al1 reported that increased weight gain during early childhood (1 to 5 years) but not during infancy (birth to 1 year) is associated with later systolic blood pressure. From the latter, they concluded that “… none of the evidence so far indicates that promotion of infant growth increases cardiovascular risk.”1 In our ...

Gas gain on single wire chambers filled with pure isobutane at low pressure

, 2004
The gas gain of single-wire chambers filled with isobutane, with cell cross-section 12x12 mm and wire diameters of 15, 25, 50 and 100 $\mu$m, has been measured at pressures ranging 12-92 Torr.
