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...

Variable detours in long-distance migration across ecological barriers and their relation to habitat availability at ground.

Ecology and evolution

Hahn S, Emmenegger T, Lisovski S, Amrhein V, Zehtindjiev P, Liechti F.
PMID: 25505540
Ecol Evol. 2014 Nov;4(21):4150-60. doi: 10.1002/ece3.1279. Epub 2014 Oct 12.

Migration detours, the spatial deviation from the shortest route, are a widespread phenomenon in migratory species, especially if barriers must be crossed. Moving longer distances causes additional efforts in energy and time, and to be adaptive, this should be...

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...

Coronary endarterectomy in left anterior descending artery combined with coronary artery bypass grafting - midterm mortality and morbidity.

Kardiochirurgia i torakochirurgia polska = Polish journal of cardio-thoracic surgery

Domaradzki W, Sanetra K, Krauze J, Kinasz L, Jankowska-Sanetra J, Świątkiewicz M, Paradowski K, Cisowski M.
PMID: 26855644
Kardiochir Torakochirurgia Pol. 2015 Dec;12(4):304-8. doi: 10.5114/kitp.2015.56778. Epub 2015 Dec 30.

INTRODUCTION: Completeness of myocardial revascularization is essential in surgical treatment of coronary artery disease. The aim of this study is to determine the effectiveness of coronary endarterectomy as an adjunct to coronary artery bypass grafting (CABG) in the most...

Paramagnetic reentrant effect in mesoscopic cylinders made of a normal metal in proximity with a superconductor.

Physical review letters

Lisowski M, Zipper E.
PMID: 11290203
Phys Rev Lett. 2001 Feb 19;86(8):1602-5. doi: 10.1103/PhysRevLett.86.1602.

We show that the paramagnetic reentrant effect observed in experiments by Mota et al. in mesoscopic cylinders made of a normal metal in proximity with a superconductor, can be caused by paramagnetic persistent currents flowing on the outer shell...

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...

Do all pure entangled states violate Bell's inequalities for correlation functions?.

Physical review letters

Zukowski M, Brukner C, Laskowski W, Wieśniak M.
PMID: 12059465
Phys Rev Lett. 2002 May 27;88(21):210402. doi: 10.1103/PhysRevLett.88.210402. Epub 2002 May 09.

Any pure entangled state of two particles violates a Bell inequality for two-particle correlation functions (Gisin's theorem). We show that there exist pure entangled N>2 qubit states that do not violate any Bell inequality for N particle correlation functions...

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...

Axial Ligand exchange in chiral macrocyclic ytterbium(III) complexes.

Inorganic chemistry

Lisowski J, Ripoli S, Di Bari L.
PMID: 14966974
Inorg Chem. 2004 Feb 23;43(4):1388-94. doi: 10.1021/ic0353918.

We investigate the role of axial ligands on the near-IR-optical and paramagnetic NMR spectra of the complex [YbL](+3) where L is the stereodefined enantiopure chiral macrocycle (L = hexaazapentacyclo[25.3.1.1(12,24).0(4,9).0(19,24)]dotriaconta-1(31),2,10,12,14,16(32),17,25,27,29-decaene). The conformation in solution of the lanthanide complex is characterized...
