Elements and roadmap for interactive molecular graphics and modeling "in the Holodeck". [PDF]
Protein SciAbstract Molecular graphics have been instrumental in advancing chemistry, drug discovery, materials science and structural biology, enabling visualization of molecular systems from static images to dynamic web displays and immersive platforms. While effective visualization is largely a solved problem, in this perspective we argue that the next ...

Multiuser Detection for Nonlinear MIMO Uplink [PDF]
IEEE Transactions on Communications, 2020 For the multiple-input multiple-output (MIMO) uplink employing high-order quadrature amplitude modulation (QAM) signaling and with nonlinear high power amplifiers (HPAs) at mobile users’ transmitters, the existing multiuser detection methods can no longer be applied. We propose a novel nonlinear multiuser detection scheme for the nonlinear MIMO uplink.

Journal of Communications and Networks, 2001 In this paper, we propose a novel scheme for iterative multiuser detection and turbo decoding. Multiuser detection is based on the soft output maximum a posteriori (MAP) detector, which passes soft metrics to the single-user turbo decoders. Parallel concatenated convolutional codes (PCCC) are employed as single user turbo-codes, where each user is ...

On robust multiuser detection [PDF]
Conference Record of the Thirty-Fourth Asilomar Conference on Signals, Systems and Computers (Cat. No.00CH37154), 2002 We study the design of multiuser detectors from an H/sup /spl infin// point of view. The H/sup /spl infin// approach is most appropriate in the situations where the statistical properties of the disturbances are not known or are too hard to model and analyze.

Low Complexity Receiver Structures for Space-Time Coded Multiple-Access Systems
EURASIP Journal on Advances in Signal Processing, 2002 Multiuser detection for space-time coded synchronous multiple-access systems in the presence of independent Rayleigh fading is considered. Under the assumption of quasi-static fading, it is shown that optimal (full diversity achieving) space-time codes ...

Bone Health After Metabolic and Bariatric Surgery: Osteometabolism Biomarkers, Bone Mineral Density, and Microarchitecture. [PDF]
Obesity (Silver Spring)ABSTRACT Objective The effects of metabolic and bariatric surgery on bone health still require further investigation. Osteometabolism biomarkers, bone microarchitecture (BM), and mineral density (BMD) of patients who have undergone Roux‐en‐Y gastric bypass (RYGB) within 2–5 years from surgery were compared to non‐surgical age‐, sex‐, and BMI‐matched ...

Adaptive minimum-BER linear multiuser detection [PDF]
2001 IEEE International Conference on Acoustics, Speech, and Signal Processing. Proceedings (Cat. No.01CH37221), 2002 An adaptive minimum bit error rate (MBER) linear multiuser detector (MUD) is proposed for DS-CDMA systems. Based on the approach of kernel density estimation for approximating the bit error rate (BER) from training data, a least mean squares (LMS) style adaptive algorithm is developed for training linear MUDs. Computer simulation results show that this
