Exploring EEG signal processing for effective filtering and classification of epileptic seizures
Abstract EEG signal processing is the process of analysing the raw electrical signals recorded by the electrodes on the scalp to obtain information about the human brain. The preprocessing of the EEG signal cleans the raw signals, feature extraction to obtain the relevant patterns, and…

Thermal memory driven compact electro-thermal modelling of phase-change memristors
Compact models of phase-change memristive devices are important for circuit- and system-level simulations. Despite this, most of the approaches available today depend on threshold-based switching or experiential conductance updates. These models reproduce fundamental SET/RESET behaviour, but these…

The profound influence of temperature on phase change memory: Challenges and research breakthroughs
Phase-change memory (PCM) is a promising nonvolatile memory technology that stores information through reversible, thermally driven phase transitions in chalcogenide materials, particularly Ge2Sb2Te5 (GST225). The significant resistance contrast between the crystalline and amorphous states enables…

Hanning FIR window filtering analysis for EEG signals
The window function is a mathematical function in signal processing that is multiplied by a signal to lessen or eliminate the impact of undesired characteristics such as spectral leakage and edge effects that might arise while analyzing finite-duration signals. The Hanning window is just one of…

Diagnostic yield and etiological spectrum of medical thoracoscopy-guided pleural biopsy in various exudative pleural effusions: experience from a rural tertiary center in north India
Exudative pleural effusions still today remain a frequent diagnostic challenge. Approximately 20-40% of cases remain undiagnosed after a pleural fluid study and closed pleural biopsy. Medical thoracoscopy (MT), a new tool, enables direct visualization and targeted pleural biopsy, substantially…
