Language features may reflect underlying cognitive and emotional processes following a traumatic event that portend clinical outcomes. The authors sought to determine whether language features from usual smartphone use were markers associated with concurrent posttraumatic symptoms and worsening or improving posttraumatic symptoms over time following a traumatic exposure. This investigation was a secondary analysis of the Advancing Understanding of RecOvery afteR traumA study, a longitudinal study of traumatic outcomes among survivors recruited from 33 emergency departments across the United States. Adverse posttraumatic sequelae were assessed over the six months following the initial traumatic exposure. Language features were extracted from usual smartphone use in a specialized app. Bivariate linear mixed models were used to identify and validate language features that are markers associated with posttraumatic symptoms. Participants were 1744 trauma survivors, with a mean age of 39 [SD = 13] years old, and 56% were female. Fourteen language features were associated with severity level of posttraumatic symptoms at specific timepoints (cross-sectional markers) and five features were associated with change in severity level of posttraumatic symptoms (longitudinal markers). References to the body and health or illness were predictive of worsening pain, somatic, and thinking/concentration/fatigue symptom severity over time. An increase in references to others was associated with improvement in somatic symptom severity over time and increases in expressions of causation or cognitive processes were associated with improvement in pain symptom severity over time. Language features derived from usual smartphone use can convey important information about health, functioning, and recovery following a traumatic event. Clinicians might utilize such information to determine who may experience a high symptom burden or risk of worsening posttraumatic symptoms.

This paper presents a compensation of variation effect of antennas for stepped-frequency radar identification systems. The antenna effects due to the variation in the antenna response and the mutual coupling degrade the target response in the identification systems. The equation used to reduce the antenna effect is derived. The simulations are demonstrated to validate the benefit of the compensation technique. The simulations are divided into several cases including different antennas and different shapes of objects. The simulation results confirm that the use of the compensation can improve the target response compared with the ideal case of without the antenna.

Investigation of myocardial dynamics through the assessment of mechanical properties of the heart is a challenging problem due to tradeoff between the heart rate and ultrasound frame rate. The objective of this study was to compare displacements estimated using radiofrequency (RF) signals with Cardiac Elastography (CE) and Speckle Tracking Echocardiography (STE) for quantifying myocardial dynamics with B-mode signals. Myocardial dynamics with CE and STE were evaluated using cumulative radial displacements in short-axis views on a left anterior descending (LAD) artery murine ligation model. Cumulative radial displacement estimated in all six segments of the left ventricle was significantly reduced following ligation with both methods. For CE, the global peak radial displacement (GPRD) reduced from 1.28 mm at baseline to 0.55 mm after 14 days and 0.43 mm after 28 days respectively. A similar trend was observed with STE with the corresponding GPRD values ranging from 0.16 mm to 0.15 mm and 0.03 mm respectively. The comparable performance with commercially available software shows the potential of cardiac elastography in studying myocardial dynamics with higher sensitivity due to the phase information present with RF signals. © 2017 IEEE.

On the construction of polar codes for achieving the capacity of marginal channels

Achieving security against adversaries with unlimited computational power is of great interest in a communication scenario. Since polar codes are capacity achieving codes with low encoding-decoding complexity and they can approach perfect secrecy rates for binary-input degraded wiretap channels in symmetric settings, they are investigated extensively in the literature recently. In this paper, a polar coding scheme to achieve secrecy capacity in non-symmetric binary input channels is proposed. The proposed scheme satisfies security and reliability conditions. The wiretap channel is assumed to be stochastically degraded with respect to the legitimate channel and message distribution is uniform. The information set is sent over channels that are good for Bob and bad for Eve. Random bits are sent over channels that are good for both Bob and Eve. A frozen vector is chosen randomly and is sent over channels bad for both. We prove that there exists a frozen vector for which the coding scheme satisfies reliability and security conditions and approaches the secrecy capacity. We further empirically show that in the proposed scheme for non-symmetric binary-input discrete memoryless channels, the equivocation rate achieves its upper bound in the whole capacity-equivocation region.
