Cartilage. 2017 Oct;8(4):391-399. doi: 10.1177/1947603516665443. Epub 2016 Sep 01.

Objective The aim of this study was to investigate whether the concentration of the anionic contrast agent ioxaglate, as quantitated by contrast-enhanced computed tomography (CECT) using a clinical cone-beam CT (CBCT) instrument, reflects biochemical, histological, and biomechanical characteristics of...

Optical characterization of directly deposited graphene on a dielectric substrate.

Optics express

Kaplas T, Karvonen L, Ahmadi S, Amirsolaimani B, Mehravar S, Peyghambarian N, Kieu K, Honkanen S, Lipsanen H, Svirko Y.
PMID: 26906863
Opt Express. 2016 Feb 08;24(3):2965-70. doi: 10.1364/OE.24.002965.

By using scanning multiphoton microscopy we compare the nonlinear optical properties of the directly deposited and transferred to the dielectric substrate graphene. The direct deposition of graphene on oxidized silicon wafer was done by utilizing sacrificial copper catalyst film....

A three-stage clinical trial design for rare disorders.

Statistics in medicine

Honkanen VE, Siegel AF, Szalai JP, Berger V, Feldman BM, Siegel JN.
PMID: 11590629
Stat Med. 2001 Oct 30;20(20):3009-21. doi: 10.1002/sim.980.

Many clinical trials of uncommon diseases are underpowered because of the difficulty of recruiting adequate numbers of subjects. We propose a clinical trial design with improved statistical power compared to the traditional randomized trial for use in clinical trials...

Velocity-fluctuation-induced anomalous kinetics of the A+A--> reaction.

Physical review. E, Statistical physics, plasmas, fluids, and related interdisciplinary topics

Hnatich M, Honkonen J.
PMID: 11088171
Phys Rev E Stat Phys Plasmas Fluids Relat Interdiscip Topics. 2000 Apr;61(4):3904-11. doi: 10.1103/physreve.61.3904.

The effect of a random velocity field on the kinetics of the single-species annihilation reaction A+A--> is analyzed near two dimensions with the aid of the perturbative renormalization group. The previously found asymptotic behavior induced by density fluctuations only...

Using multicriteria methods in environmental planning and management.

Environmental management

Lahdelma R, Salminen P, Hokkanen J.
PMID: 11029111
Environ Manage. 2000 Dec;26(6):595-605. doi: 10.1007/s002670010118.

In environmental planning and decision processes several alternatives are analyzed in terms of multiple noncommensurate criteria, and many different stakeholders with conflicting preferences are involved. Based on our experience in real-life applications, we discuss how multicriteria decision aid (MCDA)...

Anomalous scaling of a passive scalar advected by the Navier-Stokes velocity field: two-loop approximation.

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

Adzhemyan LTs, Antonov NV, Honkonen J, Kim TL.

The field theoretic renormalization group and operator-product expansion are applied to the model of a passive scalar quantity advected by a non-Gaussian velocity field with finite correlation time. The velocity is governed by the Navier-Stokes equation, subject to an...
