Design and Implementation of a Binary Phase-Shift Keying Frequency Diverse Array: Considerations and Challenges.

The frequency diverse array (FDA) is an architecture capable of beamforming in both range and angle, improving upon the traditional phased array (PA) which can only achieve beamforming in angle. The FDA employing directional modulation (DM) for secure directional communications (SDC) can reduce bit error rates (BERs) in both range and angle, again improving upon the traditional PA which can only reduce BER in angle. In this paper, we document the challenges involved in the design and implementation of a two-element linear FDA employing fast-time binary phase-shift keying (BPSK) modulations.

Inpatient Multimodal Pain Regimens Do Not Impact Hospital Length of Stay or Long-term Postoperative Opioid Use Following 1 and 2-Level Lumbar Fusion.

Study Design: Retrospective cohort study.

Objective: To determine hospital length of stay (LOS) and long-term opioid consumption among patients who received inpatient multimodal analgesia following lumbar spine surgery, as opposed to those who received opioids alone.

Summary Of Background Data: Opioids have long been the historical choice for managing postoperative pain.

Role of Altmetric Attention Scores in Evaluating the Influence of Spine Surgery Research.

Study Design: Retrospective cohort.

Objective: To analyze the annual trends in the most prevalent topics, journals, and geographic regions of the top 100 spine surgery articles, as determined by altmetric attention scores (AASs). We also describe the relationship between AAS and traditional article metrics.

Surgeon's perceptions and preferences in the management of idiopathic macular hole.

Purpose: The management of idiopathic macular holes (iMH) has evolved over time with various modifications in surgical approach. The study aimed to survey the surgeons' preferences in the management of iMH in current times.

Design: Cross-sectional descriptive survey.
