Homogeneity Pursuit [PDF]

open access: yesJournal of the American Statistical Association, 2015
This paper explores the homogeneity of coefficients in high-dimensional regression, which extends the sparsity concept and is more general and suitable for many applications. Homogeneity arises when regression coefficients corresponding to neighboring geographical regions or a similar cluster of covariates are expected to be approximately the same ...

A Fuzzy Guidance System for Rendezvous and Pursuit of Moving Targets

open access: yesRobotics, 2020
This article presents the development of a fuzzy guidance system (FGS) for unmanned aerial vehicles capable of pursuing and performing rendezvous with static and mobile targets. The system is designed to allow the vehicle to approach a maneuvering target

The Status of Turkish Subjects in The Soviet Union (1923-1953)

open access: yesYakın Dönem Türkiye Araştırmaları, 2023
The advance of the Soviet administration in the Caucasus and the establishment of its own system there appear to have taken place over a short time. However, the government needed many years to consolidate itself in the region.

Distributed Basis Pursuit [PDF]

open access: yes, 2012
We propose a distributed algorithm for solving the optimization problem Basis Pursuit (BP). BP finds the least L1-norm solution of the underdetermined linear system Ax = b and is used, for example, in compressed sensing for reconstruction.

Pursuit eye movements in dyslexic children: evidence for an immaturity of brain oculomotor structures?

open access: yesJournal of Eye Movement Research, 2020
Background: Dyslexia is a disorder found in 5–10% of school-aged children. Several studies reported visual deficits and oculomotor abnormalities in dyslexic children.

The effect of a temporary absence of target velocity information on visual tracking

open access: yesJournal of Eye Movement Research, 2010
Experiments with the Rashbass ‘step-ramp’ paradigm have revealed that the initial catchup saccade that occurs near pursuit onset uses target velocity as well as position information in its programming.

Adaptive integration of self-motion and goals in posterior parietal cortex

open access: yesCell Reports, 2022
Summary: Rats readily switch between foraging and more complex navigational behaviors such as pursuit of other rats or prey. These tasks require vastly different tracking of multiple behaviorally significant variables including self-motion state.

Guaranteed Pursuit and Evasion Times in a Differential Game for an Infinite System in Hilbert Space l2

open access: yesMathematics, 2023
The present paper is devoted to studying a pursuit differential game described by an infinite system of binary differential equations in Hilbert space l2. The control parameters of the players are subject to geometric constraints.

Dynamics of oculomotor direction discrimination [PDF]

open access: yes, 2016
Successful foveation of a dynamic target depends on good predictions of its movement direction and speed. We measured and compared the temporal dynamics of directional precision of both saccades and smooth pursuit and their interactions. We also compared

The Role of Dopamine in Anticipatory Pursuit Eye Movements: Insights from Genetic Polymorphisms in Healthy Adults [PDF]

open access: yes, 2016
There is a long history of eye movement research in patients with psychiatric diseases for which dysfunctions of neurotransmission are considered to be the major pathologic mechanism.
