Cuneiform Nucleus Stimulation Can Assist Gait Training to Promote Locomotor Recovery in Individuals With Incomplete Tetraplegia. [PDF]

Ann Neurol
Objective Impaired ability to induce stepping after incomplete spinal cord injury (SCI) can limit the efficacy of locomotor training, often leaving patients wheelchair‐bound. The cuneiform nucleus (CNF), a key mesencephalic locomotor control center, modulates the activity of spinal locomotor centers via the reticulospinal tract.

Mapping reticulospinal drive across various muscles of the upper and lower extremities. [PDF]

Exp Physiol
Abstract The reticulospinal (RS) system is a fundamental descending pathway involved in human movement control. However, the relative strength of RS projections across different muscles and its specific contributions to distinct movements are poorly understood. We systematically mapped the RS drive across a broad range of muscles in the upper and lower

Investigating the Pharmacokinetics and Efficacy of Intramammary Ceftiofur Hydrochloride in Prevention of Udder Inflammation in Non-Lactating Dairy Heifers. [PDF]

J Vet Pharmacol Ther
ABSTRACT Mastitis is the most burdensome concern for the dairy cattle industry. Antimicrobials are often prophylactically administered to dairy cows at dry‐off to reduce the risk of intramammary infection during the dry period and subsequent lactation.

Sub-Graph Based Joint Sparse Graph for Sparse Code Multiple Access Systems

IEEE Access, 2018
Sparse code multiple access (SCMA) is a promising air interface candidate technique for next-generation mobile networks, especially for massive machine-type communications. In this paper, we design a low-density parity-check (LDPC) coded SCMA detector by

Grant-Free Sparse Code Multiple Access for Uplink Massive Machine-Type Communications and Its Real-Time Receiver Design

IEEE Open Journal of Circuits and Systems, 2023
Massive Machine-type Communications (mMTCs) is a major use case for the 5G standard. The grant-free (GF) sparse-coded multiple access (SCMA) transmission is particularly spectrum efficient in the sporadic uplink traffic, which is characteristic of the ...

Enabling Sphere Decoding for SCMA [PDF]

IEEE Communications Letters, 2017
In this paper, we propose a reduced-complexity optimal modified sphere decoding (MSD) detection scheme for SCMA. As SCMA systems are characterized by a number of resource elements (REs) that are less than the number of the supported users, the channel matrix is rank-deficient, and sphere decoding (SD) cannot be directly applied.

Resource Allocation-Based PAPR Analysis in Uplink SCMA-OFDM Systems

IEEE Access, 2019
Sparse code multiple access (SCMA) is a non-orthogonal multiple access (NOMA) uplink solution that overloads resource elements (RE's) with more than one user.
