(a.) Not isotropic; having different properties in different directions; thus, crystals of the isometric system are optically isotropic, but all other crystals are anisotropic.
Example Sentences:
(1) The myocardium was assumed to be composed of a nonlinear viscoelastic, inhomogeneous, anisotropic (transversely isotropic) and incompressible material operating under adiabatic and isothermal conditions.
(2) Results from the simultaneous global analysis of the frequency domain data sets from the three proteins revealed anisotropic rotations for the macromolecule, consistent with the known elongated shape of the repressor tetramer.
(3) The spatial correlation of regional pulmonary perfusion was anisotropic in both supine and prone positions.
(4) The new theory to describe this basic mechanism shows that the vascularization of tissue causes it to behave as an anisotropic heat transfer medium.
(5) Quantitative criteria for the validity of the first Born approximation in differential polarization imaging are explicitly derived for three different types of media: (a) linearly anisotropic, (b) circularly anisotropic, and (c) linearly and circularly anisotropic (medium displaying linear birefringence and circular birefringence).
(6) Studies using scanning electron microscopic techniques permitted characterization of the nature and structure of the anisotropic elements present in dried preparations of mid-cycle cervical mucus.
(7) Such an arrangement can provice a certain measure of anisotropic disinhibition which may be responsible for specific transformations occurring in the LGNd depending upon the size and velocity of the stimulus as well as of the degree of synchronicity of temporal patterns.
(8) The structured and unstructured grid models are used to investigate recent interpretations of experimental data that concluded that more than 80% of the total defibrillation current is shunted by the anisotropic skeletal muscle thoracic cage.
(9) Propagation was more rapid in the direction perpendicular to the left anterior coronary artery than in the direction perpendicular to the base of the heart, because of the uniform anisotropic structure of the surviving muscle fibers which were arranged in tightly packed bundles oriented perpendicular to the left anterior coronary artery.
(10) Also, anisotropic atomic fluctuations and their interatomic correlations can be determined experimentally even with a relatively small number of adjustable parameters.
(11) The anisotropic conduction of ventricular muscle is a contributory factor but, on its own, is unlikely to support a pathological arrhythmia.
(12) The various degrees of prolongation of the action potentials in the centre of functional anisotropic re-entry were caused by electrotonic current flow between the two limbs of the circuit, which were closely opposed but activated with a large time difference.
(13) Anisotropic structures can be observed either at the periphery of the dendrites or isolated as small spheroliths.
(14) In each case, neither repolarization inhomogeneities (leading circle concept) nor anisotropic discontinuous propagation was the only "mechanism" involved.
(15) The changes of T1 and T2 were treated based on the assumption of two types of molecular motions: (1) isotropic "slow" motions with times approximately greater than 10(-8) s (including the rotation of a molecule as a whole) and (2) anisotropic "fast" motions with times approximately less than 10(-10) s. Experimental data show an essential increase of the scale of intramolecular mobility for the majority of side groups upon transition of the protein from the native to the molten globule state.
(16) In this paper we will show that this approach can also be applied to solve the anisotropic mixed boundary value condition problems studied in electrical impedance tomography (EIT).
(17) Experimental results are presented, and the effect of an anisotropic resolution property on the overall image quality is discussed.
(18) The flow and fracture behavior of sucrose, the model substance used in this study, were anisotropic.
(19) The purpose of this study was to study the role of anisotropic distribution of conduction velocity in the initiation and perpetuation of ventricular tachycardia in an experimental model of sustained reentrant ventricular tachycardia in the Langendorff perfused rabbit heart.
(20) The anisotropic period, 7 days long, is inscribed within the ferning period.
Trichroism
Definition:
(n.) The quality possessed by some crystals of presenting different colors in three different directions.
