Quantitative ecology is the application of advanced mathematical and statistics statistical tools to any number of problems in the field of ecology . It is a small but growing subfield in ecology, reflecting the demand among practicing ecologists to interpret ever larger and more complex data sets using quantitative reasoning. Quantitative ecologists might apply some combination of deterministic or stochastic mathematical models to theoretical questions or they might use sophisticated methods in applied statistics for experimental design and hypothesis testing . Typical problems in quantitative ecology include estimating the dynamics and status of wild populations, modeling the impacts of anthropogenic or climatic change on ecological communities, and predicting the spread of invasive species or disease outbreaks. Quantitative ecology, which mainly focuses on statistical and computational methods for addressing applied problems, is distinct from theoretical ecology which tends to explore focus on understanding the dynamics of simple mechanistic models and their implications for a general set of biological systems using mathematical arguments.

cleanup date May 2009 Quantitative Pharmacology QP is an organized approach integrating individuals from different disciplines in a combined effort to develop quantitative model s in order to solve specific, complex, and multivariate problems in drug development . QP translates the relationship s between disease , drug action , and individual variability into improved patient outcomes by leveraging improved teamwork and collaboration to enable quantitative decision making processes from Drug discovery early discovery to late stage development. QP encourages more transparent and objective study designs, as well as more data driven risk taking to optimize timelines, analyses, and decision making, resulting in greater efficiency in the drug development process. Benefits Incorporation of QP methodologies will help gain a better understanding of the mechanism of drug disease interactions and identify molecular targets with high probability of impacting disease e.g., use of proteomics and cheminformatics in the development of drug disease models select the ideal drug candidate in early drug development e.g., integrated and mechanistic Pharmacokinetics PK Pharmacodynamics PD models optimize ...

Refimprove date February 2012 In CAD CAM, quantitative invisibility QI is the number of solid bodies that obscure a point in space as projected onto a Plane geometry plane . Often, CAD engineers project a model into a plane a 2D drawing in order to denote edges that are visible with a solid line, and those that are hidden with dashed or dimmed lines. Algorithm Tracking the number of obscuring bodies gave rise to an algorithm that propagates the quantitative invisibility throughout the model. This technique uses edge coherence to speed calculations in the algorithm. However, QI really only works well when bodies are larger solids, non interpenetrating, and not transparent. A technique like this falls apart when applied to soft organic tissue as found in the human body, because there is not always a clear delineation of structures. Also, when images become too cluttered and intertwined, the contribution of this algorithm is marginal. Arthur Appel of the graphics group at Thomas J. Watson Research Center IBM Watson Research coined the term quantitative invisibility and used it in several of his papers.

Image Quantitative parasitology 1.JPG thumb 275 px Intensity histograms are helpful to get a first impression about the differences of infection between 2 or more samples. Horizontal axis infection classes, vertical axis the number of host individuals belonging to each class. Counting parasites Quantifying parasites in a sample of hosts or comparing measures of infection across two or more samples can be challenging. The parasitic infection of a sample of hosts inherently exhibits a complex pattern that cannot be adequately quantified by a single statistical measure. As the use of two or more separate indices is advisable, only two or more separate statistical tests can reliably compare infections different samples of hosts. A few of the available statistical measures have markedly different biological interpretations, while others have more or less overlapping interpretations or no interpretations at all. Therefore, one should apply measures that have clear and separate biological interpretations thus do not predict each other. Parasite individuals typically exhibit an skewness aggregated right skewed distribution among host individuals most hosts harbour few if any parasites and a few hosts harbour many of them. This quantitative feature of parasitism renders many of traditional statistical methods obsolete and requires the use of advanced computer intensive statistical methods.

no footnotes date December 2011 Quantitative Electroencephalography QEEG is the use of digital signal analysis to extend the analysis of electroencephalography EEG . Though more modern approaches such as wavelet analysis exist, the most common analytic approach uses Fourier analysis. The analog signal comprising the microvoltage time series of the EEG is sampled digitally with analog to digital technology with sampling rates adequate to over sample the signal using the Nyquist principle of exceeding twice the highest frequency being detected . Modern EEG amplifiers use adequate sampling to resolve the EEG across the traditional medical band from DC to 70 or 100 Hz, using sample rates of 250 256, 500 512, to over 1000 samples per second, depending on the intended application. The Fourier decomposes the EEG time series into a voltage by frequency spectral graph commonly called the power spectrum , with power being the square of the EEG magnitude, and magnitude being the integral average of the amplitude of the EEG signal, measured from peak to peak , across the time sampled, or epoch. The epoch length determines the frequency resolution of the Fourier, with a 1 second epoch providing a 1 Hz resolution plus minus 0.5 Hz resolution , and a 4 second epoch providing Hz, or plus minus 0.125 Hz resolution. The assumptions of the Fourier include stationarity, or the persistence of the signal from the beginning of time to eternity, so EEG transients are not well described with the Fourier. The Fourier also assumes a stable state, so wake drowsiness transitions or other state changes are not described well with the Fourier. Never the less the Fourier remains the most common form of qEEG analysis. QEEG has been accepted by for clinical application in some areas, such as cerebro vascular disorders and epilepsy, though it remains yet to be accepted in other clinical areas, such as diagnosing mild traumatic brain injury or psychiatric disorders.
