SARS‐CoV‐2 infection and venous thromboembolism after surgery: an international prospective cohort study

COVIDSurg Collaborative, GlobalSurg Collaborative, Dmitri Nepogodiev, Joana FF Simoes, more

Anaesthesia > 77 > 1 > 28 - 39

SARS‐CoV‐2 has been associated with an increased rate of venous thromboembolism in critically ill patients. Since surgical patients are already at higher risk of venous thromboembolism than general populations, this study aimed to determine if patients with peri‐operative or prior SARS‐CoV‐2 were at further increased risk of venous thromboembolism. We conducted a planned sub‐study and analysis from...

Muhammad Hamza Humayun, Pedro Ludwig Hernandez‐Martinez, Negar Gheshlaghi, Onur Erdem, more

Small > 17 > 41 > n/a - n/a

Silicon is the most prevalent material system for light‐harvesting applications; however, its inherent indirect bandgap and consequent weak absorption limits its potential in optoelectronics. This paper proposes to address this limitation by combining the sensitization of silicon with extraordinarily large absorption cross sections of quasi‐2D colloidal quantum well nanoplatelets (NPLs) and to demonstrate...

Multiclass EEG motor-imagery classification with sub-band common spatial patterns

Javeria Khan, Muhammad Hamza Bhatti, Usman Ghani Khan, Razi Iqbal

EURASIP Journal on Wireless Communications and Networking > 2019 > 2019 > 1 > 1-9

Electroencephalogram (EEG) signal classification plays an important role to facilitate physically impaired patients by providing brain-computer interface (BCI)-controlled devices. However, practical applications of BCI make it difficult to decode motor imagery-based brain signals for multiclass classification due to their non-stationary nature. In this study, we aim to improve multiclass classification...
