    • Methods, data processing apparatus and computer program products for characterising cells and the affect of treatments administered to cells are disclosed. In particular methods of identifying bi-nuclear cells are described which include capturing an image of a plurality of marked cells and processing image to obtain features of the plurality of cells. The features are analyzed to determine whether the feature is indicative of bi-nuclear cells. Those cells for which the first feature is indicative of bi-nuclear cells are identified as being bi-nuclear. Three algorithms in particular are described. A first algorithm can be used to determine the number of nuclei in an image of a nuclear component by determining the number of concave regions within the outline of the image. A second algorithm uses a measure of the amount of cytoplasmic material between a pair of nuclei to identify bi-nuclear cells. A third algorithm uses the statistics of the spatial distribution of objects to identify isolated pairs of nuclei which can be considered to be from the same cell.

    • Methods, apparatus, and computer programs for investigating and characterising side effects of a treatment having an intended or on-target effect on cells are described. The method can include identifying a group of on-target cellular features of the plurality of cells which are affected by the treatment and are related to the on-target effect. A group of off-target cellular features can also be identified which are different to the on-target cellular features and which are also affected by the treatment and which are related to the side effect. A measure of the side effect based on the off-target cellular features can be obtained. The treatment can then be characterised based on the measure of the side effect. A further method involves capturing an image of the population of treated cells and deriving cellular features from the image. An on-target effect signature, which is characteristic of the on-target effect is created from cellular features relating to cellular properties involved in the intended effect. A side effect signature, which is characteristic of a side effect to the on-target effect, is created using cellular features relating to cellular properties not involved in the intended effect. On-target effect and/or side effect metrics are obtained from the signatures which can be used to characterise the treatment.

    • A method for calculating distances between stimulus response curves (e.g., dose response curves) allows classification of stimuli. The response curves show how the phenotype of one or more cells changes in response to varying levels of the stimulus. Each “point” on the curve represents quantitative phenotype or signature for cell(s) at a particular level of stimulus (e.g., dose of a therapeutic). The signatures are multivariate phenotypic representations of the cell(s). They include various features of the cell(s) obtained by image analysis. To facilitate the comparison of stimuli, distances between points on the response curves are calculated. First, the response curves may be aligned on a coordinate representing a separate distance, r, from a common point of negative control (e.g., the point where no stimulus is applied). Integration on r may be used to compute the distance between two response curves. The distance between response curves is used to classify stimuli.
    • 用于计算刺激响应曲线(例如,剂量响应曲线)之间的距离的方法允许对刺激进行分类。 响应曲线显示了一种或多种细胞的表型如何响应刺激的不同水平而改变。 曲线上的每个“点”表示特定刺激水平(例如,治疗剂的剂量)的细胞的定量表型或特征。 签名是细胞的多变量表型表达。 它们包括通过图像分析获得的细胞的各种特征。 为了促进刺激的比较,计算响应曲线上的点之间的距离。 首先,响应曲线可以在表示来自负控制的公共点(例如,不施加刺激的点)的单独距离r的坐标上对准。 可以使用r上的积分来计算两个响应曲线之间的距离。 响应曲线之间的距离用于对刺激进行分类。

    • A laser shield (FIG. 3) for providing ocular protection against laser hazards, while still providing high photopic or scotopic transmittance and good color discrimination is disclosed. This laser shield comprises a holographic optical notch filter mirror (102) having an optical surface such that the angle (104) made by an incoming laser beam (114), which is aimed by the pupil of the user, with respect to the normal of the optical surface is less than the corresponding angle (108) made by the same incoming laser beam (114) with respect to the physical surface of the substrate. This decrease in the effective angle of incidence reduces the spectral shift of the notch (which defines the frequency that is reflected), thereby providing increased protection for the same range of angles of incidence. The holographic mirror optical surface formed can be the analog of a conventional spherical, hyperbolic, parabolic, elliptical or other aspheric mirror.

    • A method of making a holographic optical element is disclosed. The method comprises the steps of determining the separation between interference pattern planes tangent to surfaces separated by a desired distance which achieves desired optical properties at a given first wavelength and angular orientation of light in a hologram disposed on a curved surface of first shape corresponding to the shape of a curved holographic element. The angular characteristics of exposure to achieve of this separation of planes in a planar analog of the desired curved holographic element is determined. The angles of exposure of interfering light rays to achieve this separation of planes in the planar analog by exposure of a sensitive substantially planar surface at a second wavelength in order to achieve the desired separation of planes and angular characteristics are determined. A source is constructed having the desired angular exposure characteristics and having a wavelength equal to the second wavelength, the source being constructed using a pair of source sets which are activated in sequence to make the desired interference pattern while shading parts of the substrate. An interference pattern is recorded in a photosensitive substantially planar film disposed on a substantially planar substrate using the constructed source. The interference pattern is developed. The developed interference pattern acts as a transmission hologram. The sensitive film with the interference pattern recorded in it is removed from the substantially planar substrate, the developing being done before removal of the sensitive layer in order that the removal may be carried out in a lighted area. The removed sensitive layer is the adhered to a substrate having the first shape, the removed layer being stretched and bent for adhesion to the substrate.
