Brain-machine interfaces (BMI) are tools for measuring neural activity in the brain, used to treat numerous conditions. It is essential that the next generation of intracortical BMIs is wireless so as to remove percutaneous connections, i.e. wires, and the associated mechanical and infection risks. This is required for the effective translation of ...
Information and communication technology is experiencing a steep rise. The amount of digital data present on the internet is unimaginable. Images and videos have become major methods of information exchange, and they form a large chunk of this digital data. There also has been an exponential rise in digital devices that are generating large amounts...
Quantum key distribution (QKD) protocols harness fundamental quantum properties of the light to construct communication channels sensitive to eavesdropping. In order to develop the technology at large scale, one of the main challenges to overcome is the deployment cost of such systems. A significant step towards reducing deployment costs would be t...

The authors explored whether a digital literacy program, Digital Outreach for Obtaining Resources and Skills (DOORS), could improve self-reported functional skills and clinical outcomes among people with serious mental illness. The 8-week program was offered to participants receiving treatment in community mental health centers (N=113) and an inpat...

This study examined the impact of high-reliability changes to how measurement-based care questionnaires were administered to patients on rates of questionnaire completion. Medical record data were abstracted from 44,305 adult outpatient return visits to a psychiatry outpatient clinic within two 10-month periods (before and after process changes wer...
We present a learning-based channel-adaptive joint source and channel coding (CA-JSCC) scheme for wireless image transmission over multipath fading channels. The proposed method is an end-to-end autoencoder architecture with a dual-attention mechanism employing orthogonal frequency division multiplexing (OFDM) transmission. Unlike the previous work...
This papers uses stochastic geometry and queuing theory to study he scalability of long-range (LoRa) networks, accounting for duty cycling restrictions and imperfect spreading factor (SFs) orthogonality. The scalability is characterised by the joint boundaries of device density and traffic intensity per device. Novel cross-correlation factors are u...
The successful rollout of fifth-generation (5G) networks requires a full understanding of the behavior of the propagation channel, taking into account the signal formats and the frequencies standardized by the Third Generation Partnership Project (3GPP). In the past, channel characterization for 5G has been addressed mainly based on the measurement...
