This paper studies systems of polynomial equations that provide information about orientability of matroids. First, we study systems of linear equations over F2, originally alluded to by Bland and Jensen in their seminal paper on weak orientability. The Bland-Jensen linear equations for a matroid M have a solution if and only if M is weakly orientable. We use the Bland-Jensen system to determin...
The present paper investigates the performance of open-ended, growth-oriented equity schemes for the period from April 2011 to March 2015 of transition economy. Daily closing NAV of different schemes have been used to calculate the returns from the fund schemes. BSE-sensex has been used for market portfolio. The historical performance of the selected schemes were evaluated on the basis of Sharp...
This study examines the incentives in fund management due to the adoption of speci c performance measures. A mean-variance measure such as Jensens alpha incentivizes fund managers to load negative coskewness risk. This risk is shown to be priced in the UK stock market during the period January 1991December 2005, bearing a premium of 2.09% p.a. Hence, a new performance measure, the intercept of...
While reading times are often used to measure working memory load, frequency effects (such as surprisal or n-gram frequencies) also have strong confounding effects on reading times. This work uses a naturalistic audio corpus with magnetoencephalographic (MEG) annotations to measure working memory load during sentence processing. Alpha oscillations in posterior regions of the brain have been fou...
Performing different tasks, such as generating motor movements or processing sensory input, requires the recruitment of specific networks of neuronal populations. Previous studies suggested that power variations in the alpha band (8-12Hz) may implement such recruitment of task-specific populations by increasing cortical excitability in task-related areas while inhibiting population-level cortic...
