GSID: ZtAUs1tYdjIJ
AT Beck, D Lester, M Kovacs - Psychological Reports, 1973 - journals.sagepub.com

… The pattern of differences suggests different reasons for suicidal actions by males and … than were the males. The findings lend support to the notion that men's attempts stem from …

Structure and dynamics of thylakoids in land plants.

Journal of experimental botany

Pribil M, Labs M, Leister D.
PMID: 24622954
J Exp Bot. 2014 May;65(8):1955-72. doi: 10.1093/jxb/eru090. Epub 2014 Mar 12.

Thylakoids of land plants have a bipartite structure, consisting of cylindrical grana stacks, made of membranous discs piled one on top of the other, and stroma lamellae which are helically wound around the cylinders. Protein complexes predominantly located in...

Localized shear generates three-dimensional transport.

Chaos (Woodbury, N.Y.)

Smith LD, Rudman M, Lester DR, Metcalfe G.
PMID: 28456165
Chaos. 2017 Apr;27(4):043102. doi: 10.1063/1.4979666.

Understanding the mechanisms that control three-dimensional (3D) fluid transport is central to many processes, including mixing, chemical reaction, and biological activity. Here a novel mechanism for 3D transport is uncovered where fluid particles are kicked between streamlines near a...

ACBC to Balcite: Bioinspired Synthesis of a Highly Substituted High-Temperature Phase from an Amorphous Precursor.

Advanced materials (Deerfield Beach, Fla.)

Whittaker ML, Joester D.
PMID: 28452398
Adv Mater. 2017 Jul;29(26). doi: 10.1002/adma.201606730. Epub 2017 Apr 28.

Energy-efficient synthesis of materials locked in compositional and structural states far from equilibrium remains a challenging goal, yet biomineralizing organisms routinely assemble such materials with sophisticated designs and advanced functional properties, often using amorphous precursors. However, incorporation of organics...

Ammonia volatilization and nitrogen retention: how deep to incorporate urea?.

Journal of environmental quality

Rochette P, Angers DA, Chantigny MH, Gasser MO, MacDonald JD, Pelster DE, Bertrand N.
PMID: 25602404
J Environ Qual. 2013 Nov;42(6):1635-42. doi: 10.2134/jeq2013.05.0192.

Incorporation of urea decreases ammonia (NH) volatilization, but field measurements are needed to better quantify the impact of placement depth. In this study, we measured the volatilization losses after banding of urea at depths of 0, 2.5, 5, 7.5,...

Determination of the strange nucleon form factors.

Physical review letters

Shanahan PE, Horsley R, Nakamura Y, Pleiter D, Rakow PE, Schierholz G, Stüben H, Thomas AW, Young RD, Zanotti JM.
PMID: 25793800
Phys Rev Lett. 2015 Mar 06;114(9):091802. doi: 10.1103/PhysRevLett.114.091802. Epub 2015 Mar 03.

The strange contribution to the electric and magnetic form factors of the nucleon is determined at a range of discrete values of Q^{2} up to 1.4  GeV^{2}. This is done by combining a recent analysis of lattice QCD results...

Chlorophyll Fluorescence Video Imaging: A Versatile Tool for Identifying Factors Related to Photosynthesis.

Frontiers in plant science

Rühle T, Reiter B, Leister D.
PMID: 29472935
Front Plant Sci. 2018 Jan 30;9:55. doi: 10.3389/fpls.2018.00055. eCollection 2018.

Measurements of chlorophyll fluorescence provide an elegant and non-invasive means of probing the dynamics of photosynthesis. Advances in video imaging of chlorophyll fluorescence have now made it possible to study photosynthesis at all levels from individual cells to entire...

Long-term follow-up of a patient with malignant transformation of inverted papilloma into sinonasal undifferentiated carcinoma.

Allergy & rhinology (Providence, R.I.)

Orgain CA, Shibuya TY, Thompson LD, Keschner DB, Garg R, Lee JT.
PMID: 29070275
Allergy Rhinol (Providence). 2017 Oct 01;8(3):173-177. doi: 10.2500/ar.2017.8.0209.

INTRODUCTION: Inverted papillomas (IP) are benign sinonasal neoplasms, which account for 0.5-4% of all nasal tumors. IPs have been known to transform into squamous cell carcinoma in 5-15% of cases. Rarely, transformations to other malignancies have been reported. Here...

Large Area Cryo-Planing of Vitrified Samples Using Broad-Beam Ion Milling.

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

Chang IY, Joester D.
PMID: 26455924
Microsc Microanal. 2015 Dec;21(6):1616-1621. doi: 10.1017/S143192761501510X. Epub 2015 Oct 12.

On account of its excellent resolution and high throughput, cryoSEM imaging has recently seen resurgence. In this work, we report on the development of cryogenic triple ion gun milling (CryoTIGM™), a broad ion beam milling technique for cryo-planing of...

Two-dimensional (2D) nanoflakes have emerged as a class of materials that may impact electronic technologies in the near future. A challenging but rewarding work is to experimentally identify 2D materials and explore their properties. Here, we report the synthesis...

Calculation of Membrane Lipid Ratios Using Single-Pixel Time-of-Flight Secondary Ion Mass Spectrometry Analysis.

Analytical chemistry

Kassenböhmer R, Draude F, Körsgen M, Pelster A, Arlinghaus HF.
