Diffusive behavior of a greedy traveling salesman.

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

Lipowski A, Lipowska D.
PMID: 21797310
Phys Rev E Stat Nonlin Soft Matter Phys. 2011 Jun;83(6):061115. doi: 10.1103/PhysRevE.83.061115. Epub 2011 Jun 13.

Using Monte Carlo simulations we examine the diffusive properties of the greedy algorithm in the d-dimensional traveling salesman problem. Our results show that for d=3 and 4 the average squared distance from the origin (r(2)) is proportional to the...

Phase transitions in Ising models on directed networks.

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

Lipowski A, Ferreira AL, Lipowska D, Gontarek K.
PMID: 26651748
Phys Rev E Stat Nonlin Soft Matter Phys. 2015 Nov;92(5):052811. doi: 10.1103/PhysRevE.92.052811. Epub 2015 Nov 23.

We examine Ising models with heat-bath dynamics on directed networks. Our simulations show that Ising models on directed triangular and simple cubic lattices undergo a phase transition that most likely belongs to the Ising universality class. On the directed...

First-order transition with power-law singularity in models with absorbing states.

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

Lipowski A.
PMID: 11088973
Phys Rev E Stat Phys Plasmas Fluids Relat Interdiscip Topics. 2000 Sep;62(3):4401-4. doi: 10.1103/physreve.62.4401.

We study one- and two-dimensional models which undergo a transition between active and absorbing phases. The transition point in these models is of a novel type: jump of the order parameter coincides with its power-law singularity. Some arguments supported...

Criticality in a model with absorbing states.

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

Lipowski A.
PMID: 11308540
Phys Rev E Stat Nonlin Soft Matter Phys. 2001 Feb;63(2):026105. doi: 10.1103/PhysRevE.63.026105. Epub 2001 Jan 19.

We study a one-dimensional model that undergoes a transition between an active and an absorbing phase. Monte Carlo simulations supported by some additional arguments prompted us to predict the exact location of the critical point and critical exponents in...

Dynamical properties of the synchronization transition.

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

Droz M, Lipowski A.
PMID: 12786247
Phys Rev E Stat Nonlin Soft Matter Phys. 2003 May;67(5):056204. doi: 10.1103/PhysRevE.67.056204. Epub 2003 May 13.

We use spreading dynamics to study the synchronization transition (ST) of one-dimensional coupled map lattices (CML's). Recently, Baroni et al. [Phys. Rev. E 63, 036226 (2001)] have shown that the ST belongs to the directed percolation (DP) universality class...

Heat conduction and diffusion of hard disks in a narrow channel.

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

Lipowski A, Lipowska D.
PMID: 17677119
Phys Rev E Stat Nonlin Soft Matter Phys. 2007 May;75(5):052201. doi: 10.1103/PhysRevE.75.052201. Epub 2007 May 31.

Using molecular dynamics we study heat conduction and diffusion of hard disks in one-dimensional narrow channels. When collisions preserve momentum the heat conduction kappa diverges with the number of disks N as kappa approximately N alpha (alpha approximately 1/3)...

Obesity is associated with increased level of kisspeptin in mothers' blood and umbilical cord blood - a pilot study.

European review for medical and pharmacological sciences

Pruszyńska-Oszmałek E, Wojciechowska M, Krauss H, Sassek M, Leciejewska N, Szczepankiewicz D, Nowak KW, Piątek J, Nogowski L, Sliwowska JH, Kołodziejski PA.

Eur Rev Med Pharmacol Sci. 2021 Oct;25(19):5993-6002. doi: 10.26355/eurrev_202110_26877.

OBJECTIVE: Kisspeptin (KP) is a major regulator of reproductive functions. It has also been shown to be involved in the metabolic changes associated with obesity. According to the well-established concept of prenatal programming, environmental factors can influence physiological and...

The relationships between knee extensors/ flexors strength and balance control in elite male soccer players.

PeerJ

Śliwowski R, Marynowicz J, Jadczak Ł, Grygorowicz M, Kalinowski P, Paillard T.

PeerJ. 2021 Nov 16;9:e12461. doi: 10.7717/peerj.12461. eCollection 2021.

BACKGROUND: Strength and balance are important factors for soccer players to be successful. This study's aim was to determine the relationship between lower-limb muscle strength and balance control in elite male soccer players (METHODS: Concentric isokinetic strength (peak torque...

Surface-Related Kinetic Models for Anaerobic Digestion of Mi-crocrystalline Cellulose: The Role of Particle Size.

Materials (Basel, Switzerland)

Piątek M, Lisowski A, Dąbrowska M.
PMID: 33498568
Materials (Basel). 2021 Jan 20;14(3). doi: 10.3390/ma14030487.

In this work, for modelling the anaerobic digestion of microcrystalline cellulose, two surface-related models based on cylindrical and spherical particles were developed and compared with the first-order kinetics model. A unique dataset consisting of particles with different sizes, the...

The Influence of Zero Shear Viscosity of TLA-Modified Binder and Mastic Composition on the Permanent Deformation Resistance of Mastic Asphalt Mixture.

Kołodziej K, Bichajło L, Siwowski T.
PMID: 34576391
Materials (Basel). 2021 Sep 09;14(18). doi: 10.3390/ma14185167.

Mastic asphalt (MA) has been particularly popular in recent years for bridge pavements due to many advantages such as easy application, good waterproofing properties, and high durability. However, the drawback of mastic asphalt in comparison to other asphalt mixtures...
