Manor B, Costa M, Hu K, Newton E, Starobinets O, Kang H, et al.
J Appl Physiol (1985) . 2010 Oct; 109(6):1786-91. PMID: 20947715
The degree of multiscale complexity in human behavioral regulation, such as that required for postural control, appears to decrease with advanced aging or disease. To help delineate causes and functional...

J Neurotrauma . 2009 Feb; 26(2):227-33. PMID: 19196074
Reliable and noninvasive assessment of cerebral blood flow regulation is a major challenge in acute care monitoring. This study assessed dynamics of flow regulation and its relationship to asymmetry of...

Hu K, Peng C, Huang N, Wu Z, Lipsitz L, Cavallerano J, et al.
Physica A . 2008 Apr; 387(10):2279-2292. PMID: 18432311
Cerebral autoregulation (CA) is an important mechanism that involves dilation and constriction in arterioles to maintain relatively s cerebral blood flow in response to changes of systemic blood pressure. Traditional...

Hu K, Peng C, Czosnyka M, Zhao P, Novak V
Cardiovasc Eng . 2007 Dec; 8(1):60-71. PMID: 18080758
Cerebral autoregulation (CA) is an most important mechanism responsible for the relatively constant blood flow supply to brain when cerebral perfusion pressure varies. Its assessment in nonacute cases has been...

Ashkenazy Y, Ivanov P, Havlin S, Peng C, Yamamoto Y, Goldberger A, et al.
Comput Cardiol . 2003 Nov; 27:139-42. PMID: 14632010
The cardiac interbeat (RR) increment time series can be decomposed into two sub-sequences: a magnitude series and a sign series. The authors show that the sign sequence, a simple binary...

Peng C, Mietus J, Liu Y, Lee C, Hausdorff J, Stanley H, et al.
Ann Biomed Eng . 2002 Jul; 30(5):683-92. PMID: 12108842
We sought to quantify the fractal scaling properties of human respiratory dynamics and determine whether they are altered with healthy aging and gender. Continuous respiratory datasets (obtained by inductive plethysmography)...

Hausdorff J, Ashkenazy Y, Peng C, Ivanov P, Stanley H, Goldberger A
Physica A . 2002 May; 302(1-4):138-47. PMID: 12033228
We present a random walk, fractal analysis of the stride-to-stride fluctuations in the human gait rhythm. The gait of healthy young adults is scale-free with long-range correlations extending over hundreds...

Physica A . 2001 Sep; 273(1-2):46-69. PMID: 11543356
The purpose of this report is to describe some recent progress in applying scaling concepts to various systems in nature. We review several systems characterized by scaling laws such as...

Physica A . 2001 Sep; 270(1-2):309-24. PMID: 11543220
Even under healthy, basal conditions, physiologic systems show erratic fluctuations resembling those found in dynamical systems driven away from a single equilibrium state. Do such "nonequilibrium" fluctuations simply reflect the...
