Behind the mask: Random and selective masking in transformer models applied to specialized social science texts.

open access: yesPLoS ONE
Transformer models such as BERT and RoBERTa are increasingly popular in the social sciences to generate data through supervised text classification. These models can be further trained through Masked Language Modeling (MLM) to increase performance in ...

Incorporating Employee Heterogeneity into Default Rules for Retirement Plan Selection [PDF]

open access: yesJournal of Human Resources, 2010
This paper examines the effect of incorporating individual-level heterogeneity into default rules for retirement plan selection. We use data from a large employer that transitioned from a defined benefit (DB) plan to a defined contribution (DC) plan, offering existing employees a choice of plans.

His bundle pacing–is it the final frontier of physiological pacing ?–A single centre experience from the Indian sub–Continent

open access: yesIndian Heart Journal, 2020
Background: Long term right ventricular pacing can have deleterious effects on left ventricular (LV) function. His bundle pacing (HBP), a novel procedure can probably circumvent this setback.

Cognition and the Default Mode Network in Children with Sickle Cell Disease: A Resting State Functional MRI Study. [PDF]

open access: yesPLoS ONE, 2016
Cerebrovascular complications are frequent events in children with sickle cell disease, yet routinely used techniques such as Transcranial Doppler (TCD), Magnetic Resonance (MRI) and Angiography (MRA), insufficiently explain the cause of poor cognitive ...

Functional topography of the thalamo-cortical system during development and its relation to cognition

open access: yesNeuroImage, 2020
The thalamus has complex connections with the cortex and is involved in various cognitive processes. However, little is known about the age-related changes of thalamo-cortical connections and their relation to cognitive abilities.

Topological fractionation of resting-state networks. [PDF]

open access: yesPLoS ONE, 2011
Exploring topological properties of human brain network has become an exciting topic in neuroscience research. Large-scale structural and functional brain networks both exhibit a small-world topology, which is evidence for global and local parallel ...

Support Vector Machines with Evolutionary Feature Selection for Default Prediction [PDF]

open access: yesSSRN Electronic Journal, 2012
Predicting default probabilities is at the core of credit risk management and is becoming more and more important for banks in order to measure their client's degree of risk, and for firms to operate successfully. The SVM with evolutionary feature selection is applied to the CreditReform database.

RELIGION AS A CONTROL GUIDE: ON THE IMPACT OF RELIGION ON COGNITION

open access: yesZygon, 2010
Religions commonly are taken to provide general orientation in leading one's life. We develop here the idea that religions also may have a much more concrete guidance function in providing systematic decision biases in the face of cognitive‐control ...

Disrupted Anti-correlation Between the Default and Dorsal Attention Networks During Hyperthermia Exposure: An fMRI Study

open access: yesFrontiers in Human Neuroscience, 2020
Environmental hyperthermia is a common risk factor for occupational safety in many situations due to decreased vigilance performances. Previously, we have reported that decreased resting-state functional connectivity within the default mode network (DMN)
