On the calculation of information-theoretical measures of diversity

diversity

Karr JR.
GSID: EAb8fgmN4p0J
M Lloyd, JH Zar, JR Karr - American Midland Naturalist, 1968 - JSTOR

… ABSTRACT: Computing formulae are given, along with an example, to show that the Shannon and Brillouin indices of diversity can be calculated with equal ease. A table is presented for rapid calculation of both indices, as well as...

Zero-coupling-gap degenerate band edge resonators in silicon photonics.

Optics express

Burr JR, Reano RM.
PMID: 26698725
Opt Express. 2015 Nov 30;23(24):30933-42. doi: 10.1364/OE.23.030933.

Resonances near regular photonic band edges are limited by quality factors that scale only to the third power of the number of periods. In contrast, resonances near degenerate photonic band edges can scale to the fifth power of the...

Ceruloplasmin and Hypoferremia: Studies in Burn and Non-Burn Trauma Patients.

Antioxidants (Basel, Switzerland)

Dubick MA, Barr JL, Keen CL, Atkins JL.
PMID: 26785343
Antioxidants (Basel). 2015 Mar 06;4(1):153-69. doi: 10.3390/antiox4010153.

OBJECTIVE: Normal iron handling appears to be disrupted in critically ill patients leading to hypoferremia that may contribute to systemic inflammation. Ceruloplasmin (Cp), an acute phase reactant protein that can convert ferrous iron to its less reactive ferric form...

A case of metaplastic breast cancer in a man.

Journal of surgical case reports

Barr JG, Jane Clayton ES, Sotheran W.
PMID: 24964410
J Surg Case Rep. 2013 Feb 07;2013(2). doi: 10.1093/jscr/rjs047.

Metaplastic breast cancers (MPBCs) represent

Detection of Botulinum Toxins A, B, E, and F in Foods by Endopep-MS.

Journal of agricultural and food chemistry

Kalb SR, Krilich JC, Dykes JK, Lúquez C, Maslanka SE, Barr JR.
PMID: 25578960
J Agric Food Chem. 2015 Feb 04;63(4):1133-1141. doi: 10.1021/jf505482b. Epub 2015 Jan 22.

Botulism is caused by exposure to botulinum neurotoxins (BoNTs). BoNTs are proteins secreted by some species of clostridia; these neurotoxins are known to interfere with nerve impulse transmission, thus causing paralysis. Botulism may be contracted through consumption of food...

Quantitative prediction and clinical evaluation of an unexplored herb-drug interaction mechanism in healthy volunteers.

CPT: pharmacometrics & systems pharmacology

Gufford BT, Barr JT, González-Pérez V, Layton ME, White JR, Oberlies NH, Paine MF.
PMID: 26904384
CPT Pharmacometrics Syst Pharmacol. 2015 Dec;4(12):701-10. doi: 10.1002/psp4.12047. Epub 2015 Nov 28.

Quantitative prediction of herb-drug interaction risk remains challenging. A quantitative framework to assess a potential interaction was used to evaluate a mechanism not previously tested in humans. The semipurified milk thistle product, silibinin, was selected as an exemplar herbal...

Improving patient discharge process using electronic medication input tool and on-line guide to arranging follow-ups.

BMJ quality improvement reports

Barr R, Chin KY, Yeong K.
PMID: 26734179
BMJ Qual Improv Rep. 2013 Sep 17;2(1). doi: 10.1136/bmjquality.u756.w711. eCollection 2013.

Complete, accurate and timely discharge summaries (TTOs) enable effective communication between hospital teams and GPs. It can prevent adverse events and reduce hospital readmission rates (1). If the discharge summary does not contain important information (e.g. follow-up arrangements, accurate...

Improving transmission rates of electronic discharge summaries to GPs.

BMJ quality improvement reports

Barr R, Chin KY, Yeong K.
PMID: 26734187
BMJ Qual Improv Rep. 2013 Sep 17;2(1). doi: 10.1136/bmjquality.u756.w1013. eCollection 2013.

Discharge summaries are a vital tool to communicate information from Hospital to Primary Care teams; updating GPs about what happened during an admission, and handing over care detailing any follow up care required. Historically, Discharge Summaries have been posted...

Noncoding RNAs in Neurodegenerative Diseases.

ISRN neurology

Rege SD, Geetha T, Pondugula SR, Zizza CA, Wernette CM, Babu JR.
PMID: 23738143
ISRN Neurol. 2013 Apr 30;2013:375852. doi: 10.1155/2013/375852. Print 2013.

Noncoding RNAs are widely known for their various essential roles in the development of central nervous system. It involves neurogenesis, neural stem cells generation, maintenance and maturation, neurotransmission, neural network plasticity, formation of synapses, and even brain aging and...

High Confinement Mode and Edge Localized Mode Characteristics in a Near-Unity Aspect Ratio Tokamak.

Physical review letters

Thome KE, Bongard MW, Barr JL, Bodner GM, Burke MG, Fonck RJ, Kriete DM, Perry JM, Schlossberg DJ.
PMID: 27176526
Phys Rev Lett. 2016 Apr 29;116(17):175001. doi: 10.1103/PhysRevLett.116.175001. Epub 2016 Apr 27.

Tokamak experiments at near-unity aspect ratio A≲1.2 offer new insights into the self-organized H-mode plasma confinement regime. In contrast to conventional A∼3 plasmas, the L-H power threshold P_{LH} is ∼15× higher than scaling predictions, and it is insensitive to...

NADH Oxidase Activity of Plasma Membranes of Soybean Hypocotyls Is Activated by Guanine Nucleotides.

Plant physiology

Morre DJ, Brightman AO, Barr R, Davidson M, Crane FL.
PMID: 12231849
Plant Physiol. 1993 Jun;102(2):595-602. doi: 10.1104/pp.102.2.595.

The activity of an auxin-stimulated NADH oxidase of the plasma membrane of hypocotyls of etiolated soybean (Glycine max Merr.) seedlings responded to guanine and other nucleotides, but in a manner that differed from that of enzymes coupled to the...
