Covert Research [PDF]

, 2019
The purpose of this entry is to explore the long-standing controversy surrounding deception, secrecy, and ethical transgression, which often make up covert research. This is done in a threefold manner.

Video_2_Enhanced Eye Velocity With Backup Saccades in vHIT Tests of a Menière Disease Patient: A Case Report.MOV

, 2021
Reduced eye velocity and overt or covert compensatory saccades during horizontal head impulse testing are the signs of reduced vestibular function. However, here we report the unusual case of a patient who had enhanced eye velocity during horizontal head

ATXN8OS Intermediate Expansion Acts as a Genetic Modifier in Spinocerebellar Ataxia Type 48 (SCA48/STUB1)

Movement Disorders, EarlyView.
Abstract Background Association between monoallelic STUB1 variant and expanded ATXN8OS alleles was recently reported, suggesting a pathogenic interaction that may influence spinocerebellar ataxia type 48 (SCA48) phenotype. Objectives We investigated the frequency and clinical impact of ATXN8OS in a large cohort of STUB1 carriers compared to individuals

Elements of Feed-Forward and Feedback Control in Drosophila Body Saccades [PDF]

, 2007
I have developed a new experimental preparation of the fruit fly, Drosophila melanogaster. A fly is glued to a steel pin, which is held in the field between two magnets such that the fly is free to rotate about only one axis. Such "magnetically tethered"

Dynamic Performance Enhancement of a High‐Agility Hypersonic Mechanical System via a Learning‐Augmented Robust Control Architecture

International Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT The design of control systems for high‐agility mechanical systems operating in extreme environments is a significant challenge in nonlinear dynamics. This paper addresses the complex dynamic control problem of a hypersonic interceptor, modeled as a multi‐input multi‐output (MIMO) mechanical system characterized by strong aerodynamic cross ...

Learned statistical regularity modulates anticipatory micro-saccades toward suppressed distractor locations

Nature Communications
Learned statistical regularity enables individuals to suppress locations associated with salient distractors, yet the mechanisms underlying this suppression remain unclear.

Designing ZV and ZVD Input Shapers Using the Designed Fixed Output Response Method to Suppress Residual Vibration of Overhead Crane Systems With Trolley Traveling and Payload Hoisting

International Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT Classical Zero Vibration (ZV) and Zero Vibration and Derivative (ZVD) input shapers are designed around a fixed nominal natural frequency and cannot accommodate the time‐varying dynamics introduced when an overhead crane simultaneously travels and hoists a payload.

Integrated Molecular Autopsy in a Highly Consanguineous Perinatal Cohort With Severe Malformations and Strong Genetic Susceptibility

Prenatal Diagnosis, EarlyView.
ABSTRACT Objective To evaluate the diagnostic yield of integrated molecular autopsy (IMA) by combining deep post‐mortem phenotyping with exome (ES) and targeted genome sequencing (GS) for prenatally detected anomalies. Method This retrospective study evaluated 28 perinatal cases (22 fetuses, six neonates) with severe anomalies, normal first‐tier ...

The temporal relationship between reduction of early imitative responses and the development of attention mechanisms

BMC Neuroscience, 2003
Background To determine whether early imitative responses fade out following the maturation of attentional mechanisms, the relationship between primitive imitation behaviors and the development of attention was examined in 4-month-old infants.

Timing of target discrimination in human frontal eye fields [PDF]

, 2004
Frontal eye field (FEF) neurons discharge in response to behaviorally relevant stimuli that are potential targets for saccades. Distinct visual and motor processes have been dissociated in the FEF of macaque monkeys, but little is known about the visual ...
