A novel density-based neural mass model for simulating neuronal network dynamics with conductance-based synapses and membrane current adaptation.

Neural Netw 2021 Jun 11;143:183-197. Epub 2021 Jun 11.

Department of Neurology, National Cheng Kung University Hospital, College of Medicine, National Cheng Kung University, Tainan, Taiwan. Electronic address:

Despite its success in understanding brain rhythms, the neural mass model, as a low-dimensional mean-field network model, is phenomenological in nature, so that it cannot replicate some of rich repertoire of responses seen in real neuronal tissues. Here, using a colored-synapse population density method, we derived a novel neural mass model, termed density-based neural mass model (dNMM), as the mean-field description of network dynamics of adaptive exponential integrate-and-fire (aEIF) neurons, in which two critical neuronal features, i.e. Read More

Correlating subword articulation with lip shapes for embedding aware audio-visual speech enhancement.

Neural Netw 2021 Jun 8;143:171-182. Epub 2021 Jun 8.

School of Electrical and Computer Engineering, Georgia Institute of Technology, Atlanta, GA, USA.

In this paper, we propose a visual embedding approach to improve embedding aware speech enhancement (EASE) by synchronizing visual lip frames at the phone and place of articulation levels. We first extract visual embedding from lip frames using a pre-trained phone or articulation place recognizer for visual-only EASE (VEASE). Next, we extract audio-visual embedding from noisy speech and lip frames in an information intersection manner, utilizing a complementarity of audio and visual features for multi-modal EASE (MEASE).

J Environ Manage 2021 Jun 19;295:112907. Epub 2021 Jun 19.

Department of Economics, COMSATS University Islamabad, Pakistan. Electronic address:

This paper explores the features of accounting for the national carbon emission inventory under four different system boundaries, including the presently operational territorial production-based accounting (PBA) practised by the UNFCCC. Using a recently published input-output table with the base year for 2013-2014, the study calculates India's 'Nationally Determined Contribution (NDC)' to the mitigation of carbon emissions using production-based, consumption-based, sharing-based and equity-based accounting. The study finds India as a net importer of carbon emissions, especially for its high emission-intensive capital and energy goods import such that the country is bearing the minimum burden of emission reduction responsibility.
