Injury assessment in three low-resource settings: a reference for worldwide estimates.

Lancet (London, England)

Gupta S, Wren SM, Kamara TB, Shrestha S, Kyamanywa P, Wong EG, Groen RS, Nwomeh BC, Kushner AL, Price RR.
PMID: 26313066
Lancet. 2015 Apr 27;385:S2. doi: 10.1016/S0140-6736(15)60797-8. Epub 2015 Apr 26.

BACKGROUND: Trauma has become a worldwide pandemic. Without dedicated public health interventions, fatal injuries will rise 40% and become the 4th leading cause of death by 2030, with the burden highest in low-income and middle-income countries (LMICs). The aim...

Radiation-Induced Helium Nanobubbles Enhance Ductility in Submicron-Sized Single-Crystalline Copper.

Nano letters

Ding MS, Du JP, Wan L, Ogata S, Tian L, Ma E, Han WZ, Li J, Shan ZW.
PMID: 27249672
Nano Lett. 2016 Jul 13;16(7):4118-24. doi: 10.1021/acs.nanolett.6b00864. Epub 2016 Jun 06.

The workability and ductility of metals usually degrade with exposure to irradiation, hence the phrase "radiation damage". Here, we found that helium (He) radiation can actually enhance the room-temperature deformability of submicron-sized copper. In particular, Cu single crystals with...

Reducing the stochasticity of crystal nucleation to enable subnanosecond memory writing.

Science (New York, N.Y.)

Rao F, Ding K, Zhou Y, Zheng Y, Xia M, Lv S, Song Z, Feng S, Ronneberger I, Mazzarello R, Zhang W, Ma E.
PMID: 29123020
Science. 2017 Dec 15;358(6369):1423-1427. doi: 10.1126/science.aao3212. Epub 2017 Nov 09.

Operation speed is a key challenge in phase-change random-access memory (PCRAM) technology, especially for achieving subnanosecond high-speed cache memory. Commercialized PCRAM products are limited by the tens of nanoseconds writing speed, originating from the stochastic crystal nucleation during the...

Probing the Reaction Mechanism of Aluminum/Poly(vinylidene fluoride) Composites.

The journal of physical chemistry. B

DeLisio JB, Hu X, Wu T, Egan GC, Young G, Zachariah MR.
PMID: 27228361
J Phys Chem B. 2016 Jun 23;120(24):5534-42. doi: 10.1021/acs.jpcb.6b01100. Epub 2016 Jun 14.

Energetic thin films with high mass loadings of nanosized components have been recently fabricated using electrospray deposition. These films are composed of aluminum nanoparticles (nAl) homogeneously dispersed in an energetic fluoropolymer binder, poly(vinylidene fluoride) (PVDF). The nascent oxide shell...

Internal carotid artery dissection and pseudoaneurysm formation with resultant ipsilateral hypoglossal nerve palsy.

Radiology case reports

Cruciata G, Parikh R, Pradhan M, Shah J, Greif E, Stein EG.
PMID: 28491191

Craniocervical artery dissection is a potentially disabling condition caused by an intimal tear allowing blood to enter and dissect the media in the cranial direction which can occur spontaneously or as a result of trauma. When the dissection extends...

Growth Conditions Control the Elastic and Electrical Properties of ZnO Nanowires.

Nano letters

Wang X, Chen K, Zhang Y, Wan J, Warren OL, Oh J, Li J, Ma E, Shan Z.
PMID: 26510098
Nano Lett. 2015 Dec 09;15(12):7886-92. doi: 10.1021/acs.nanolett.5b02852. Epub 2015 Nov 05.

Great efforts have been made to synthesize ZnO nanowires (NWs) as building blocks for a broad range of applications because of their unique mechanical and mechanoelectrical properties. However, little attention has been paid to the correlation between the NWs...

Indirect Self-Destructive Behavior Among Elderly Patients in Nursing Homes: A Research Agenda.

The American journal of geriatric psychiatry : official journal of the American Association for Geriatric Psychiatry

Conwell Y, Pearson J, DeRenzo EG.
PMID: 28531006
Am J Geriatr Psychiatry. 1996 Spring;4(2):152-163. doi: 10.1097/00019442-199621420-00007. Epub 2012 Aug 15.

Although suicide is rare in nursing homes, indirect self-destructive behaviors (ISDBs), such as the refusal to eat or take life-sustaining medications, are commonplace. For some, ISDB represents a cry for help, whereas in others it is a reasoned behavioral...

Lanthanoid/Alkali Metal β-Triketonate Assemblies: A Robust Platform for Efficient NIR Emitters.

Chemistry (Weinheim an der Bergstrasse, Germany)

Reid BL, Stagni S, Malicka JM, Cocchi M, Sobolev AN, Skelton BW, Moore EG, Hanan GS, Ogden MI, Massi M.

The reaction of hydrated lanthanoid chlorides with tribenzoylmethane and an alkali metal hydroxide consistently resulted in the crystallization of neutral tetranuclear assemblies with the general formula [Ln(Ae⋅HOEt)(L)4 ]2 (Ln=Eu(3+) , Er(3+) , Yb(3+) ; Ae=Na(+) , K(+) , Rb(+)...

A Second Amorphous Layer Underneath Surface Oxide.

Microscopy and microanalysis : the official journal of Microscopy Society of America, Microbeam Analysis Society, Microscopical Society of Canada

Microsc Microanal. 2017 Feb;23(1):173-178. doi: 10.1017/S143192761700006X.

Formation of a nanometer-scale oxide surface layer is common when a material is exposed to oxygen-containing environment. Employing aberration-corrected analytical transmission electron microscopy and using single crystal SnSe as an example, we show that for an alloy, a second...

Evidence for climate change in the satellite cloud record.

Nature

Norris JR, Allen RJ, Evan AT, Zelinka MD, O'Dell CW, Klein SA.
PMID: 27398619
Nature. 2016 Aug 04;536(7614):72-5. doi: 10.1038/nature18273. Epub 2016 Jul 11.

Clouds substantially affect Earth's energy budget by reflecting solar radiation back to space and by restricting emission of thermal radiation to space. They are perhaps the largest uncertainty in our understanding of climate change, owing to disagreement among climate...
