Scientists Test New Class Pain Relievers
2016/6/12
A research team at Duke University has discovered a potential new class of small-molecule drugs that simultaneously block two sought-after targets in the treatment of pain.These proof-of-concept exper...
First-class Runtime Generation of High-performance Types using Exotypes
First-class Runtime Generation High-performance Types Exotypes
2016/5/24
We introduce exotypes, user-defined types that combine the flexibility of meta-object protocols in dynamically-typed languages with the performance control of low-level languages. Like objects in dyna...
Exploring Semantic Inter-class Relationships (SIR) for Zero-shot Action Recognition
Exploring Semantic Inter-class Relationships Zero-shot Action Recognition
2016/1/22
Automatically recognizing a large number of action cat-egories from videos is of significant importance for video understanding. Most existing works focused on the design of more discriminative featur...

Strong law of large number of a class of super-diffusions.
Obtaining Analytic Derivatives for a Class of Discrete-Choice Dynamic Programming Models
Analytic Derivatives Discrete-Choice Dynamic Programming Models
2015/9/18
This paper shows how to recursively calculate analytic first and second derivatives of the likelihood function generated by a popular version of a discrete-choice, dynamic programming model, allowing ...
A Class of Lyapunov Functionals for Analyzing Hybrid Dynamical Systems
Lyapunov Functionals Analyzing Hybrid Dynamical Systems
2015/7/10
In this paper, we introduce a new class of Lyapunov functionals for analyzing hybrid dynamical systems. This class can be thought of as a generalization of the Lyapunov functional introduced by Yakubo...
An ADMM Algorithm for a Class of Total Variation Regularized Estimation Problems
Signal processing algorithms stochastic parameters parameter estimation
2015/7/9
We present an alternating augmented Lagrangian method for convex optimization problems where the cost function is the sum of two terms, one that is separable in the variable blocks, and a second that ...
Complexity of Non-Adaptive Optimization Algorithms for a Class of Diffusions
Global optimization average-case complexity diffusion processes
2015/7/8
This paper is concerned with the analysis of the average error in approximating the global minimum of a 1-dimensional, time-homogeneous diffusion by non-adaptive methods. We derive the limiting distri...
Nonexistence of a Class of Variate Generation Schemes
Regenerative processes Random variable generation
2015/7/8
Motivated by a problem arising in the regenerative analysis of discrete-event system simulation, we ask whether a certain class of random variate generation schemes exists or not. Under very reasonabl...
The Mean Number-in-System Vector Range for a Multi-Class Queueing Network
networks of servers surjections onto multifunctions queueing
2015/7/6
In a multiclass network of queues, natural sufficient conditions are given for the mean number-in-system vector to cover the nonnegative orthant as the arrival rate vector varies over the stable domai...
