Entropy spikes as a signature of Lifshitz transitions in the Dirac materials.

Scientific reports

Tsaran VY, Kavokin AV, Sharapov SG, Varlamov AA, Gusynin VP.
PMID: 28860524
Sci Rep. 2017 Aug 31;7(1):10271. doi: 10.1038/s41598-017-10643-0.

We demonstrate theoretically that the characteristic feature of a 2D system undergoing N consequent Lifshitz topological transitions is the occurrence of spikes of entropy per particle s of a magnitude ±ln2/(J - 1/2) with 2 ≤ J ≤ N...

Glycine N-Methyltransferase Deficiency: A Member of Dysmethylating Liver Disorders?.

JIMD reports

Barić I, Erdol S, Saglam H, Lovrić M, Belužić R, Vugrek O, Blom HJ, Fumić K.
PMID: 27207470
JIMD Rep. 2017;31:101-106. doi: 10.1007/8904_2016_543. Epub 2016 May 21.

Glycine N-methyltransferase deficiency is an inherited disorder of methionine metabolism, reported so far in only four patients and characterised by permanent hypermethioninemia. This disorder has been considered as probably benign because moderate hepatomegaly in two patients was the only...

Development of a versatile rotating ring-disc electrode for in situ pH measurements.

Analytica chimica acta

Zimer AM, Medina da Silva M, Machado EG, Varela H, Mascaro LH, Pereira EC.

Anal Chim Acta. 2015 Oct 15;897:17-23. doi: 10.1016/j.aca.2015.09.047. Epub 2015 Oct 08.

There are some electrocatalytic reactions in which the key parameter explaining their behavior is a local change in pH. Therefore, it is of utter importance to develop an electrode that could quantify this parameter in situ, but also be...

OBJECTIVE: The aim of this study was to evaluate the microtensile bond strength (μTBS) of different flowable composite resins placed in different configuration factors (C-factors) into Class I cavities.MATERIALS AND METHODS: Fifty freshly extracted human molars were divided into...

Effect of boundary conditions on the character of ambipolar diffusion in electrolytes.

Physical review. E, Statistical, nonlinear, and soft matter physics

Chikina I, Shikin VB, Varlamov AA.
PMID: 26274165
Phys Rev E Stat Nonlin Soft Matter Phys. 2015 Jul;92(1):012310. doi: 10.1103/PhysRevE.92.012310. Epub 2015 Jul 15.

We discuss the details of ambipolar relaxation of the electric field in liquid asymmetric electrolytes to its stationary value. It is demonstrated that the account for finite boundary conditions modifies the existing concepts of this diffusion process. In particular,...

Determination of isosorbide dinitrate in arterial plasma, synthetic serum and pharmaceutical formulations by linear sweep voltammetry on a gold electrode.

Talanta. 2001 Aug 30;55(2):255-62. doi: 10.1016/s0039-9140(01)00416-7.

Isosorbide dinitrate (ISDN) is reduced voltammetrically at gold working electrode surface in aqueous sodium sulfite solution and produces a voltammogram with its peak current proportional to the concentration of ISDN in the range of 1.3-2340 mug ml(-1). Sodium sulfite...
