The genetical evolution of social behaviour
- I. J. Theor. Biol.
, 1964
"... A genetical mathematical model is described which allows for interactions between relatives on one another's fitness. Making use of Wright's Coefficient of Relationship as the measure of the proportion of replica genes in a relative, a quantity is found which incorporates the maximizing p ..."

and possibility of limited self-sacrifices. Special cases of the model are used to show (a) that selection in the social situations newly covered tends to be slower than classical selection, (b) how in populations of rather non-dispersive organisms the model may apply to genes affecting dispersion, and (c) how
Rendering of Surfaces from Volume Data
- IEEE COMPUTER GRAPHICS AND APPLICATIONS
, 1988
"... The application of volume rendering techniques to the display of surfaces from sampled scalar functions of three spatial dimensions is explored. Fitting of geometric primitives to the sampled data is not required. Images are formed by directly shading each sample and projecting it onto the picture ..."

viewing rays to form an image. The technique is simple and fast, yet displays surfaces exhibiting smooth silhouettes and few other aliasing artifacts. The use of selective blurring and super-sampling to further improve image quality is also described. Examples from two applications are given: molecular
Strategy-Proofness and Arrow’s Conditions: Existence and Correspondence Theorems for Voting Procedures and Social Welfare Functions
- J. Econ. Theory
, 1975
"... Consider a committee which must select one alternative from a set of three or more alternatives. Committee members each cast a ballot which the voting procedure counts. The voting procedure is strategy-proof if it always induces every committee member to cast a ballot revealing his preference. I pro ..."

QUANTITATIVE ANALYSIS OF GAS NON-SELECTIVE GAS SENSORS MIXTURES WITH
"... The selectivity of gas-sensor systems is improved by the use of a sensor array (consisting of non-selective and non-linear sensor elements) combined with the application of data-transformation and subsequent pattern-recogni-tion methods. This process is described, As an example, a quantitative gas a ..."

Greedy spectral embedding
"... Spectral dimensionality reduction methods and spectral clustering methods require computation of the principal eigenvectors of an n × n matrix where n is the number of examples. Following up on previously proposed techniques to speed-up kernel methods by focusing on a subset of m examples, we study ..."

the feature space projection of the non-selected examples on the subspace spanned by the selected examples, to estimate the embedding function based on all the data, which yields considerably better estimation of the embedding function. This algorithm can be formulated in an online setting and we can bound
Improving Preparation for Non-Selective Postsecondary Education: Assessment and Accountability Issues
, 2003
"... The biggest student preparation problems are evidenced in the approximately 80 % of the students who go to minimal or non-selective institutions including community colleges (Adelman, 2001; U.S. Department of Education, 2001). These students are accepted because they are 18 years old or have passed ..."

Linear Objects: logical processes with built-in inheritance
, 1990
"... We present a new framework for amalgamating two successful programming paradigms: logic programming and object-oriented programming. From the former, we keep the declarative reading of programs. From the latter, we select two crucial notions: (i) the ability for objects to dynamically change their ..."

Coil sensitivity encoding for fast MRI. In:
- Proceedings of the ISMRM 6th Annual Meeting,
, 1998
"... New theoretical and practical concepts are presented for considerably enhancing the performance of magnetic resonance imaging (MRI) by means of arrays of multiple receiver coils. Sensitivity encoding (SENSE) is based on the fact that receiver sensitivity generally has an encoding effect complementa ..."

THEORY AND METHODS In this section SENSE theory is presented and methods for image reconstruction from sensitivity encoded data are derived. The theory addresses the most general case of combining gradient
Human Face Detection in Visual Scenes
, 1995
"... We present a neural network-based face detection system. A retinally connected neural network examines small windows of an image, and decides whether each window contains a face. The system arbitrates between multiple networks to improve performance over a single network. We use a bootstrap algorith ..."

This eliminates the difficult task of manually selecting non-face training examples, which must be chosen to span the entire space of non-face images. Comparisons with other state-of-the-art face
Emergence of cooperation and evolutionary stability in finite populations. Nature
, 2004
"... The problem of cooperation1−8 is that defection is evolutionarily stable. If everybody in a population defects and one individual cooperates then this indi-vidual has a lower payoff and will be opposed by selection. Thus, the emergence of cooperation is thought to require specific mechanisms: for ex ..."

The standard game dynamical formulation, which captures the essence of the problem, is the Prisoner’s Dilemma. In the non-repeated game
