Short-term hedge fund performance
Hedge fund returns are often explained using linear factor models such as Fung and Hsieh (2004). However, since most hedge funds live only for 3years, these linear regressions are subject toExpand

Funding Illiquidity Implied by S&P 500 Derivatives
Based on the typical positions of S&P 500 option market makers, we derive a funding illiquidity measure from quoted prices of S&P 500 derivatives. Our measure significantly affects the returns ofExpand

Gender differences in the recognition of spatially transformed figures: Behavioral data and event-related potentials (ERPs)
The gender differences in accuracy, reaction time (RT) and amplitude of the early P1 and N1 components of ERPs during recognition of previously memorized objects after their spatial transformationExpand

Trajectories of shifting dipole sources of visual evoked potentials across the human brain
Visual evoked potentials in response to images of a set of horizontal and vertical lines or crosses were recorded from the brains of 18 human subjects in 34 leads. Inverse EEG analyses were used forExpand

Temporal and topographic characteristics of evoked potentials in the conflict of two consecutive visual stimuli in a working memory task
Behavioral reactions and brain mechanisms involved in processing two matching or mismatching (conflicting) visual stimuli were studied in healthy subjects (mean age 22.57 ± 0.46 years). LineExpand

Behavioral and electrographical features of recognition of forward-masked complex images: The effect of categorical similarity of the target and masking stimuli
In psychophysical and neurophysiological experiments, the subjects recognized images of two categories, “animals” and “objects.” The images of the same categories differing from the target stimuliExpand

Mechanisms of orientation sensitivity in the human visual system: Part I. Behavioral characteristics of orientation sensitivity. Influence of the task type, experimental conditions, and gender
Orientation sensitivity in the human visual system was studied in three experiments. In the first experiment, 134 subjects determined orientation of the segments of short lines by selecting it from aExpand

Location of the dipoles of the P1 wave of visual evoked potential in the human brain
Line fragments and their intersections are the basic properties of most objects in the visual world [3]; therefore, their rapid and reliable detection is important for image recognition. It isExpand

Effects of emotional expression of an irrelevant face image on recognition of visual stimuli
Psychophysiological experiments were performed on 34 healthy subjects. We analyzed the accuracy and latency of motor response in recognizing two types of complex visual stimuli, animals and objects,Expand

Effects of line orientation in visual evoked potentials. Spatial dynamics, and gender differences of neural oblique effect
The aim of the study was to investigate neural mechanisms of orientation discrimination in humans by recording the 128-channel event-related potentials (ERPs) of the brain. Stimuli wereExpand
