Brain connectivity changes associated with episodic recollection decline in aging: A review of fMRI studies

open access: yesFrontiers in Aging Neuroscience, 2022
With advancing age, individuals experience a gradual decline in recollection, the ability to retrieve personal experiences accompanied by details, such as temporal and spatial contextual information. Numerous studies have identified several brain regions

Altruism in networks: the effect of connections [PDF]

open access: yesBiology Letters, 2011
Why are individuals altruistic to their friends? Theory suggests that individual, relationship and network factors will all influence the levels of altruism; but to date, the effects of social network structure have received relatively little attention.

New Dimensions of Connectivity in the Asia-Pacific [PDF]

open access: yes, 2021
There is no bigger policy agenda in the East Asian region than connectivity. Costs of international connectivity are indeed falling, in the movement of goods, services, people and data, leading to greater flows, and to the reorganisation of business and ...

ADHD Children Identification Based on EEG Using Effective Connectivity Techniques

open access: yes, 2021
This paper presents a novel method to identify the Attention deficit hyperactivity disorder (ADHD) children using electroencephalography (EEG) signals and effective connectivity techniques. In this study, the original EEG data is pre-filtered and divided

Close or connected: Distance and connectivity effects on transport in networks [PDF]

open access: yesPhysical Review E, 2011
We develop an analytical approach which provides the dependence of the mean first-passage time (MFPT) for random walks on complex networks both on the target connectivity and on the source-target distance. Our approach puts forward two strongly different behaviors depending on the type - compact or non compact - of the random walk.

The Effect of the China Connect

open access: yesSSRN Electronic Journal, 2019
We document the effect on Chinese firms of the Shanghai (Shenzhen)-Hong Kong Stock Connect. The Connect was an important capital account liberalization introduced in the mid-2010s. It created a channel for cross-border equity investments into a selected set of Chinese stocks while China's overall capital controls policy remained in place.

Top-Down Modulations from Dorsal Stream in Lexical Recognition: An Effective Connectivity fMRI Study [PDF]

open access: yes, 2012
Both the ventral and dorsal visual streams in the human brain are known to be involved in reading. However, the interaction of these two pathways and their responses to different cognitive demands remains unclear.
