Amygdala enlargement associated with remote epileptogenic lesions

open access: yesEpilepsia, EarlyView.
Abstract Objective To determine the prevalence and possible causes of amygdala enlargement in patients with drug‐resistant temporal lobe epilepsy. Methods Patients were retrospectively identified via a radiology information system and a large language model.

Indoor air quality monitoring and source apportionment using low-cost sensors

open access: yesEnvironmental Research Communications
Understanding of the various sources of indoor air pollution requires indoor air quality (IAQ) data that is usually lacking. Such data can be obtained using unobtrusive, low-cost sensors (LCS).

Assessing the Fiscal Costs and Benefits of A8 Migration to the UK [PDF]

open access: yes, 2009
A8 immigrants who are eligible to receive state benefits are 60% less likely to claim for them than the native population -- and are 13% less likely to do so adjusting for demographics.

Thalamic connectivity mirrors spatial maps of network dysfunction in nonlesional focal epilepsy

open access: yesEpilepsia, EarlyView.
Abstract Objective Focal epilepsy is increasingly conceptualized as a network disorder, yet the extent to which network dysfunction reflects a shared phenotype remains unknown. Spatially conserved patterns of network dysfunction may implicate a centralized mechanism underlying widespread impairment.

Intracranial electroencephalographic approaches in the intensive care unit: Safety, feasibility, and coverage

open access: yesEpilepsia, EarlyView.
Abstract Objective Nonconvulsive epileptic activity is common after acute brain injury and contributes to neuronal injury and poor outcomes. Although intracranial electroencephalography (iEEG) improves detection compared with surface EEG (suEEG), it currently relies on focal recordings of epileptic dynamics.

Identification and Characterization of Atmospheric Nickel-Containing Particles in Guangzhou After the Implementation of the Clean Fuel Policy

open access: yesToxics
Nickel, as a toxic trace element in fine particulate matter (PM2.5), has detrimental effects on both air quality and human health. Based on measurements from 2020 to 2021 using a single-particle aerosol mass spectrometer (SPAMS), this study investigates ...

Identification in source apportionment using geometry

open access: yes
Source apportionment analysis, which aims to quantify the attribution of observed concentrations of multiple air pollutants to specific sources, can be formulated as a non-negative matrix factorization (NMF) problem. However, NMF is non-unique and typically relies on unverifiable assumptions such as sparsity and uninterpretable scalings.

Stereo‐EEG mapping of visual working memory with task‐related high‐gamma modulations

open access: yesEpilepsia, EarlyView.
Abstract Objective We describe a safe, informative, and easy‐to‐implement approach for presurgical mapping of visual working memory (VWM) with stereo‐electroencephalography (SEEG). Methods Twenty‐four patients with drug‐resistant epilepsy, 11–23 years of age, performed a single‐probe change detection VWM task, during SEEG monitoring.

Novel planning pipeline utilizing the Surgical Theater system for pediatric epilepsy surgery

open access: yesEpilepsia Open, EarlyView.
Abstract Objective Advances in the analysis and collation of radiographic datasets have enhanced presurgical planning for various neurosurgical procedures, including clipping of cerebral aneurysms, surgical resection of tumors, and arteriovenous malformation management.
