What's the difference between constraint and duality?

Constraint


Definition:

  • (n.) The act of constraining, or the state of being constrained; that which compels to, or restrains from, action; compulsion; restraint; necessity.

Example Sentences:

  • (8) Continuing pressure on household finances during the next 12 months will no doubt remain a constraint."

  • (10) His anti-politics act may just be a shtick – pretending he's still on Have I Got News for You, satirising politics even though he's right at the centre of it – but it liberates him from the usual constraints.
  • (11) Given that lattice constraints strongly inhibit large-scale conformational changes these results allow us to identify the average solution structure with the 'open' conformer determined crystallographically.
  • (12) A dynamic optimization technique to minimize jerk cost under the constraint on jerk input was applied to interpret the results, assuming that a major goal of skilled movements was to produce optimally smooth movements.
  • (13) Its main advantages, when compared to previously available programs using the variable target function algorithm, are a significant reduction of the computation time, and a novel treatment of experimental distance constraints involving diastereotopic groups of hydrogen atoms that were not individually assigned.
  • (14) For one, the ability to raise a larger deposit is acting as a constraint.
  • (15) When the constraints are high, a Michaelis-Menten equation can be used to model the kinetics for interfacial concentrations lower than the concentration leading to the maximum reaction rate.
  • (16) Estimators of the model parameters are defined under general exact and stochastic linear constraints.
  • (17) A careful reorganization of priorities would thus be helpful in improving neonatal care in Jamaica, even in the presence of financial constraints.
  • (18) Emergence and spread of antibiotic-resistant bacteria is augmented in settings in which treatment may be inadequate because of socioeconomic constraints and where there is crowding and poor sanitation.
  • (19) The estrogen receptor seems to have a moderate tolerance for bulky substituents: All of the halogen and halomethyl substituents bind with an affinity at least 50% that of estradiol; in the three atom alkyl series, the affinity declined markedly from propargyl (44%) and allyl (38%) to propyl (5%), suggestive of detailed steric constraints or a preference for unsaturation.
  • (20) Bias is controlled by the use of least-squares curve fitting for all assays, and constraints on the elimination of outlier points.

Duality


Definition:

  • (n.) The quality or condition of being two or twofold; dual character or usage.

Example Sentences:

  • (1) The most important conclusions for basic research on 'fast fibers', for clinical ophthalmo-electromyography and for the duality concept of eyemovement control are given.
  • (2) New-Hebrides Condominium, an archipelago in the South Pacific, is a country with a special socio-political environment, due to the duality of its French-British regime.
  • (3) It is not easy to see a simple outline in the progress of the idea of duality, because it did not develop evenly or reach the stage of general acceptance.
  • (4) The intracranial click image with long disparities and duality threshold was evaluated.
  • (5) The weight distribution of S for RI demonstrates the heterogeneity of this material, and the variation in the weight distribution with ionic strength demonstrates the duality of structure in RI.
  • (6) We show that the diversity-selection duality of Darwinian evolution is achieved at this state if we start from four different monomers capable of forming two complementary pairs.
  • (7) These observations give a new convincing support of the genetic basis of the molecular duality of DNA ligases.
  • (8) It is a show, in some ways, nostalgic for the dualities of 60s protest (currently celebrated in the V&A exhibition You Say You Want a Revolution?
  • (9) The existence of two types of neurons corresponding to these two fibres cannot yet be asserted, but seems very likely, perhaps connected with the hormonal duality of the magnocellular nuclei.
  • (10) In the light of the cases reported, it would appear that the scintigraphic picture of the "hot" nodule is more in favor of a duality between the latter and healthy tissue with respect to iodine than of a hypersensitivity to TSH.
  • (11) As a consequence, family attachment styles, which proceed-throughout development-together with personal identity construction processes, stress the notion of relationship as a dialectical and interactive process, defining the irreducible duality of human experience, in which the personal individuality construction is linked, since the earliest phases of life, to the significant relationships.
  • (12) Collectively, these findings demonstrate that ET-1 exerts a potent duality of action in rabbit TSM which varies significantly with maturation, wherein 1) age-dependent differences in airway relaxation are associated with changes in the evoked release of bronchodilatory prostaglandins and 2) maturational differences in airway contraction are associated with changes in Ins(1,4,5)P3 accumulation and extracellular Ca2+ mobilization, coupled to differences in PKC activation.
  • (13) An explanation of this apparent duality is suggested by recent reports that Bof is a corepressor of genes that are regulated by the phage C1 repressor, including the autoregulated c1 gene itself.
  • (14) We discuss whether this duality is caused by the triggering of different B cell subpopulations at different developmental stages, preprogramed to one or the other pathway or whether the final direction of development depends on the microenvironment of individual dividing cells.
