To comprehensively assess regional landslide hazards, we propose a geospatial approach that jointly evaluates both the probability of occurrence (susceptibility) and potential destructive power (intensity) within a single framework, overcoming the limitations of previous studies that treated these two disaster scenarios independently. Focusing on the largest landslide event triggered by the Wenchuan earthquake in China, we collected landslide occurrence and count data at the slope unit level, alongside 18 environmental factors, including seismic data. To enable this multi-hazard single-framework evaluation, we employed two Bayesian spatial joint regressions: the spatial shared component model (SSCM) and the spatial shared hyperparameter model (SSHM).

Introduction: Stroke is a major cause of morbidity and mortality worldwide. While electroencephalography (EEG) offers valuable data on post-stroke brain activity, qualitative EEG assessments may be misinterpreted. Therefore, we examined the potential of quantitative EEG (qEEG) to identify key band frequencies that could serve as potential electrophysiological biomarkers in stroke patients.

While psychophysical evidence suggests spatial dependencies in duration perception, few studies have directly tested the neural link between temporal and spatial processing. Using ultra-high-field functional MRI and neuronal-based modeling, we investigated how and where the processing and the representation of a visual stimulus duration is linked to that of its spatial location.

The topographic organization of category-selective responses in human ventral occipitotemporal cortex (VOTC) and its relationship to regions subserving language functions is remarkably uniform across individuals. This arrangement is thought to result from the clustering of neurons responding to similar inputs, constrained by intrinsic architecture and tuned by experience. We examined the malleability of this organization in individuals with unilateral resection of VOTC during childhood for the management of drug-resistant epilepsy.

Article Synopsis
- Electrical impedance tomography (EIT) is a non-invasive imaging technique that captures the bioelectrical impedance of the chest wall and has recently evolved to produce 3D images rather than just single-plane views.
- A new prototype of a multi-slice EIT system was tested on a 62-year-old female patient with severe pneumonia, showcasing its ability to generate detailed 3D images that closely matched traditional CT scans.
- The study revealed an unusual airflow pattern in pneumonia patients, where air entered the upper lung regions first, differing from healthy individuals, highlighting the system’s potential for better understanding lung function in disease contexts.
