Measuring segregation: an activity space approach [PDF]

open access: yesJournal of Geographical Systems, 2010
While the literature clearly acknowledges that individuals may experience different levels of segregation across their various socio-geographical spaces, most measures of segregation are intended to be used in the residential space. Using spatially aggregated data to evaluate segregation in the residential space has been the norm and thus individual's ...

Landing and catalytic characterization of individual nanoparticles on electrode surfaces [PDF]

open access: yes, 2012
We demonstrate a novel and versatile pipet-based approach to study the landing of individual nanoparticles (NPs) on various electrode materials without any need for encapsulation or fabrication of complex substrate electrode structures, providing great ...

Correlates, facilitators and barriers of physical activity among primary care patients with prediabetes in Singapore – a mixed methods approach

open access: yesBMC Public Health, 2020
BackgroundPrimary care patients with prediabetes is a priority group in the clinical, organisational and policy contexts. Engaging in regular physical activity is crucial to prevent diabetes for this group.

An active approach to spoken language processing [PDF]

open access: yesACM Transactions on Speech and Language Processing, 2006
State of the art data-driven speech and language processing systems require a large amount of human intervention ranging from data annotation to system prototyping. In the traditional supervised passive approach , the system is trained on a given number of annotated data samples and evaluated using a separate test ...

Comprehensive School Physical Activity Programs: Background and Implications [PDF]

open access: yes, 2018
Recent estimates suggest that youth spend approximately 80-93% of their working hours in a sedentary state, such as sitting or resting longer than usual (Institute of Medicine, 2013).

A Rank-Based Approach to Active Diagnosis [PDF]

open access: yesIEEE Transactions on Pattern Analysis and Machine Intelligence, 2013
The problem of active diagnosis arises in several applications such as disease diagnosis and fault diagnosis in computer networks, where the goal is to rapidly identify the binary states of a set of objects (e.g., faulty or working) by sequentially selecting, and observing, potentially noisy responses to binary valued queries.

Neural activity classification with machine learning models trained on interspike interval series data

open access: yes, 2020
The flow of information through the brain is reflected by the activity patterns of neural cells. Indeed, these firing patterns are widely used as input data to predictive models that relate stimuli and animal behavior to the activity of a population of ...

Precise multimodal optical control of neural ensemble activity. [PDF]

open access: yes, 2018
Understanding brain function requires technologies that can control the activity of large populations of neurons with high fidelity in space and time. We developed a multiphoton holographic approach to activate or suppress the activity of ensembles of ...

A logic programming approach to activity recognition [PDF]

open access: yesProceedings of the 2nd ACM international workshop on Events in multimedia, 2010
We have been developing a system for recognising human activity given a symbolic representation of video content. The input of our system is a set of time-stamped short-term activities detected on video frames. The output of our system is a set of recognised long-term activities, which are pre-defined temporal combinations of short-term activities. The
