In this paper, we develop optimum and suboptimum receivers for jointly detecting two cochannel continuous phase modulated (CPM) signals. These receivers are based upon Laurent's representation of binary CPM as the sum of a nite number of pulse amplitude modulated signals. We also provide a review of the Laurent representation and its application to the design of optimum and suboptimum single-ch...
INTRODUCTION The upper esophageal sphincter (UES) is composed largely of the cricopharyngeus muscle (CP) and acts as the gatekeeper to the esophagus. There are multiple methods of treating UES dysfunction, but myotomy has been shown to be the most definitive means. We aim to evaluate the difference between open and endoscopic CP myotomy (CPM). METHODS A retrospective review of all patients un...
In this paper, we discuss CPM-OFDMA (Continuous Phase Modulation Orthogonal Frequency Division Multiple Access) a novel modulation that maps a discrete-time CPM into a spectrally efficient DFTspread OFDMA transmission. Three CPM-OFDMA schemes are developed based on discrete-time variants of PCM/FM, SOQPSK-TG and ARTM-CPM telemetry modulations. Simulations reveal that spectrally efficient CPM-OF...
Increased pressure pain sensitivity and impaired descending pain control have been associated with chronic pain, but knowledge on the variability in the adult general population is lacking. Pressure pain thresholds (PPTs) and descending pain control assessed using conditioned pain modulation (CPM) were recorded in a randomly selected sample (n = 2,199, 53% female) of the Danish adult general po...
BACKGROUND Enhancement of the midface can be achieved with volumizing hyaluronic acid (HA) fillers. OBJECTIVE The objective of this study was to compare the safety and effectiveness of Cohesive Polydensified Matrix® 26 mg/mL HA gel (CPM-26) and Vycross® 20 mg/ml HA gel (VYC-20) in a controlled, randomized, evaluator-blind, split-face clinical study. PATIENTS AND METHODS Subjects with modera...
In this paper, we investigate the performance of a serially concatenated CPM-OFDM (Continuous Phase Modulation Orthogonal Frequency Division Multiplexing) scheme in various frequency selective fading environments that are typical for aeronautical telemetry. CPM-OFDM is a novel modulation technique that assigns the sampled, complex outputs of a CPM to a set of orthogonal subcarriers for a DFT-pr...
We studied host immune parameters which might be related to the activity and the pathogenetic mechanism of chronic active hepatitis. The subjects consisted of 45 cases with hepatitis B virus surface antigen (HBsAg)-positive chronic active hepatitis (CAH), 44 HBsAg-negative CAH, 22 with inactive chronic hepatitis, and 45 cases of normal persons, hepatitis B virus (HBV) carriers, or the patients ...
OBJECTIVES/HYPOTHESIS To describe indications, management, and outcomes of endoscopic CO2 laser cricopharyngeal myotomy (CPM). STUDY DESIGN Case series with chart review. METHODS All patients treated with endoscopic CO2 laser CPM over a 6-year period were identified. A retrospective chart review was performed for surgical indication, history and physical examinations, and swallow evaluation...
Central pontine myelinolysis (CPM) is an acute demyelinating neurological disorder affecting primarily the central pons and is frequently associated with rapid correction of hyponatremia. Common clinical manifestations of CPM include spastic quadriparesis, dysarthria, pseudobulbar palsy, and encephalopathy of various degrees; however, coma, "locked-in" syndrome, or death can occur in most sever...
OBJECTIVE To systematically review the literature regarding postoperative rehabilitation for articular cartilage repair: (1) does the use of continuous passive motion (CPM) enhance healing, and if so, what parameters should be applied? (2) Can active range of motion (AROM) be used in place of or with CPM? (3) When can individuals safely resume weight bearing (WB) following repair? DATA SOURCE...
