Objective Risk factor modification is key to preventing subsequent cardiac events after a heart attack. This study was designed to investigate the disparity between preventive guidelines and clinical practice among smoking patients. Methods The study was carried out in smokers admitted with myocardial infarction (MI). Atotal of 275 patients who had been regularly followed for over one year after MI were randomly selected and enrolled in this *** investigated changes in smoking behavior and the adherence rate to ACC/AHA Guidelines for secondary prevention in patients with coronary artery disease at the time of, and one year after, the index event. Results The study population consisted of 275 patients (97.1% males) with a mean age of 57.0 ±11.2 years. Achievement of target goals at one year was as follows: smoking cessation, 52.3%; blood pressure, 83.9%; HbA1c, 32.7%; lipid profile, 65.5%; and body mass index (BMI), 50.6%. Over one year, 80% of the patients attempted to quit smoking; 27% of them re-started smoking within one month after discharge while 65% succeeded in cessation of smoking. At one year, only 52% of the patients overall had stopped smoking. From the multivariate logistic analysis including smoking patterns and clinical characteristics, the severity of coronary artery disease was the only independent predictor for smoking cessation (Relative risk (RR): 1.230; P = 0.022). Conclusions Only a small percentage of MI patients adhere to guidelines for secondary prevention and a sizable proportion fail to stop smoking. These findings underscore the need for an effective patient education system.

Soft electromechanical sensors have led to a new paradigm of electronic devices for novel motion-based wearable applications in our daily lives. However, the vast amount of random and unidentified signals generated by complex body motions has hindered the precise recognition and practical application of this technology. Recent advancements in artificial-intelligence technology have enabled significant strides in extracting features from massive and intricate data sets, thereby presenting a breakthrough in utilizing wearable sensors for practical applications. Beyond traditional machine-learning techniques for classifying simple gestures, advanced machine-learning algorithms have been developed to handle more complex and nuanced motion-based tasks with restricted training data sets. Machine-learning techniques have improved the ability to perceive, and thus machine-learned wearable soft sensors have enabled accurate and rapid human-gesture recognition, providing real-time feedback to users. This forms a crucial component of future wearable electronics, contributing to a robust human–machine interface. In this review, we provide a comprehensive summary covering materials, structures and machine-learning algorithms for hand-gesture recognition and possible practical applications through machine-learned wearable electromechanical sensors.

作者： han WU Jinhuan WANG Institute of Mathematics School of ScienceHebei University of Technology

In this paper, we explore state-based potential games using the semi-tensor product of ***, applying the potential equation, we derive both a necessary and sufficient condition as well as a sufficient condition to verify whether a state-based game qualifies as a potential game. Next, we present two static equivalence conditions of state-based potential games. We then delve into dynamic equivalence. We propose a criterion that allows us to identify state-based games that are dynamically equivalent to state-based potential games and share similar dynamic properties. Ultimately, we introduce the concept of state-based networked evolutionary games. We provide a necessary and sufficient condition to ensure that a state-based networked evolutionary game can be classified as a state-based potential game.

Track-Before-Detect(TBD) is an efficient method to detect dim targets for radars. Conventional TBD usually follows an approximate motion model of the target, which may cause an inaccurate integration of the target energy. A TBD technique on basis of pseudo-spectrum in mixed coordinates adopting an accurate motion model for bistatic radar system is developed in this *** predicted position in bistatic polar plane is derived according to a nonlinear function that exactly describes the constant Cartesian velocity motion. Then around the predicted position, a pseudo-spectrum is formulated and its samples are accumulated to the integration frame for energy integration. The evolution of the state and the procedure of accumulation of the target energy are derived elaborately. The superior performance of the proposed method is demonstrated by some simulations.
