We present new measurements of electron scattering from high-momentum nucleons in nuclei. These data allow an improved determination of the strength of two-nucleon correlations for several nuclei, including light nuclei where clustering effects can, for the first time, be...

The study of exclusive π(±) electroproduction on the nucleon, including separation of the various structure functions, is of interest for a number of reasons. The ratio RL=σL(π-)/σL(π+) is sensitive to isoscalar contamination to the dominant isovector pion exchange amplitude,...

Resting and Postexercise Heart Rate Detection From Fingertip and Facial Photoplethysmography Using a Smartphone Camera: A Validation Study.

JMIR mHealth and uHealth

Yan BP, Chan CK, Li CK, To OT, Lai WH, Tse G, Poh YC, Poh MZ.
PMID: 28288955
JMIR Mhealth Uhealth. 2017 Mar 13;5(3):e33. doi: 10.2196/mhealth.7275.

BACKGROUND: Modern smartphones allow measurement of heart rate (HR) by detecting pulsatile photoplethysmographic (PPG) signals with built-in cameras from the fingertips or the face, without physical contact, by extracting subtle beat-to-beat variations of skin color.OBJECTIVE: The objective of our...

Dissolution of plutonium(IV) hydroxide by desferrioxamine siderophores and simple organic chelators.

Inorganic chemistry

Ruggiero CE, Matonic JH, Reilly SD, Neu MP.
PMID: 12099858
Inorg Chem. 2002 Jul 15;41(14):3593-5. doi: 10.1021/ic015591o.

Plutonium is thought to exist mostly as low soluble plutonium(IV) species in the environment and, therefore, has low potential of becoming mobile. Due to their prevalence and high solution stability constants for Pu(IV), microbial siderophores could significantly affect plutonium...

Prey availability and selective foraging in shorebirds.

Animal behaviour

Backwell PRY, O'HARA PD, Christy JH.
PMID: 9642009
Anim Behav. 1998 Jun;55(6):1659-67. doi: 10.1006/anbe.1997.0713.

Accurate measurements of prey availability are vital to our understanding of foraging behaviour, particularly prey selectivity. In the present study, observations of shorebirds foraging for fiddler crabs on intertidal mudflats demonstrate that prey availability depends both on the temporal...

Polarization transfer in the 4He(e-->,e'p-->)3H reaction up to Q2=2.6 (GeV/c)2.

Phys Rev Lett. 2003 Aug 01;91(5):052301. doi: 10.1103/PhysRevLett.91.052301. Epub 2003 Jul 29.

We have measured the proton recoil polarization in the 4He(e-->,e(')p-->)4H reaction at Q(2)=0.5, 1.0, 1.6, and 2.6 (GeV/c)(2). The measured ratio of polarization transfer coefficients differs from a fully relativistic calculation, favoring the inclusion of a medium modification of...

A Mathematical Treatment of Munch's Pressure-Flow Hypothesis of Phloem Translocation.

Plant physiology

Christy AL, Ferrier JM.
PMID: 16658599
Plant Physiol. 1973 Dec;52(6):531-8. doi: 10.1104/pp.52.6.531.

The steady state solutions of two mathematical models are used to evaluate Münch's pressure-flow hypothesis of phloem translocation. The models assume a continuous active loading and unloading of translocate but differ in the site of loading and unloading and...
