Risk as Feelings
, 2001
"... Virtually all current theories of choice under risk or uncertainty are cognitive and consequentialist. They assume that people assess the desirability and likelihood of possible outcomes of choice alternatives and integrate this information through some type of expectation-based calculus to arrive a ..."

Numerical integration of the Cartesian equations of motion of a system with constraints: molecular dynamics of n-alkanes
- J. Comput. Phys
, 1977
"... A numerical algorithm integrating the 3N Cartesian equations of motion of a system of N points subject to holonomic constraints is formulated. The relations of constraint remain perfectly fulfilled at each step of the trajectory despite the approximate character of numerical integration. The method ..."

(MD), which has been widely used in the past for studying simple liquids and solids, has more recently been applied to molecular systems with internal degrees of freedom such as N, [l], H,O [2] and even C,H,, [3]. In applying the MD method three problems arise: (a) the choice of a suitable mechanical

It is widely deployed within Google as the storage platform for the generation and processing of data used by our service as well as research and development efforts that require large
Variable Selection via Nonconcave Penalized Likelihood and its Oracle Properties
, 2001
"... Variable selection is fundamental to high-dimensional statistical modeling, including nonparametric regression. Many approaches in use are stepwise selection procedures, which can be computationally expensive and ignore stochastic errors in the variable selection process. In this article, penalized ..."

penalized likelihood functions. The proposed ideas are widely applicable. They are readily applied to a variety of parametric models such as generalized linear models and robust regression models. They can also be applied easily to nonparametric modeling by using wavelets and splines. Rates of convergence
Approximate Statistical Tests for Comparing Supervised Classification Learning Algorithms
, 1998
"... This article reviews five approximate statistical tests for determining whether one learning algorithm outperforms another on a particular learning task. These tests are compared experimentally to determine their probability of incorrectly detecting a difference when no difference exists (type I err ..."

A Rate-Adaptive MAC Protocol for Multi-Hop Wireless Networks
, 2001
"... Wireless local area networks (W-LANs) have become increasingly popular due to the recent availability of affordable devices that are capable of communicating at high data rates. These high rates are possible, in part, through new modulation schemes that are optimized for the channel conditions bring ..."

bringing about a dramatic increase in bandwidth efficiency. Since the choice of which modulation scheme to use depends on the current state of the transmission channel, newer wireless devices often support multiple modulation schemes, and hence multiple data rates, with mechanisms to switch between them

Exploiting choice: Instruction fetch and issue on an implementable simultaneous multithreading processor
- IN PROCEEDINGS OF THE 23RD ANNUAL INTERNATIONAL SYMPOSIUM ON COMPUTER ARCHITECTURE

"... Simultaneous multithreading is a technique that permits multiple independent threads to issue multiple instructions each cycle. In previous work we demonstrated the performance potential of simultaneous multithreading, based on a somewhat idealized model. In this paper we show that the throughput ga ..."

A comparative study of energy minimization methods for Markov random fields
- IN ECCV

Theories of electoral behaviour are typically elaborated to explain features of particular political systems. Most theories are focused in the US (made by US scholars) having presidential elections in mind. In turn, most of their European counterparts focus on national Parliament elections. National politics pre-eminence has lead to a national outlook over all other types of elections. Thus, it might not sound strange that a common research question in local, regional and supranational elections is how much dependent are these “other ” elections on the national ones. To our view, there are two main types of answer corresponding to two groups of theories on electoral change across different types of elections. First is what we will call dependency theories. These theories seek to explain two common features, notably a fall in turnout from one election to the other and a loss of support by incumbent. The “midterm ” weakness of US presidential parties has been explained by “surge and decline ” (Campbell 1960) and “referendum ” theories (Tufte 1975), and each has two or more versions. Both bodies of theory influenced the development of the “second-order” elections scheme (Reif and Schmitt 1980) which-inspired by lower turnout at European
