Detection of sleep apnea is the one of the major tasks in sleep medicine. Various methods have been applied to detect sleep apnea by analyzing different bio-signals. This paper introduces an innovative algorithm that analyze slope of nasal airflow signal in polysomnography. In this study, slope is obtained by the moving average of an absolute differentiation of a signal with 3.8 seconds' time window followed by segmentation of 1 second. Apnea threshold is determined by 10% of the slope of normal breathing. If segments having slope below apnea threshold appear for 10 consecutive segments, those segments are marked as apnea. The presented algorithm analyzed polysomnography records from 13 subjects and detected 2500 apnea events. Performance of presented algorithm was evaluated by comparing its results against the sleep specialist's manual scoring on same records. The overall agreement rate between the two was 95.36% (κ=0.86). In considering its simplicity and lower computational load, the presented algorithm is robust and useful.

Following the increase in the global aging population, the importance of monitoring various disease-related biomarkers at an early stage has increased to ensure the health of the elderly. In an aging society, point-of-care (POC) systems are needed to care for elderly people who have physical and mental disorders. In light of the increasing prominence of POC systems, there is a growing effort to address the limitations associated with conventional receptors in wearable devices by substituting them with molecularly imprinted polymer (MIP). MIPs are well-known synthetic receptors engineered with specific binding cavities based on the "lock and key" principle. They could be synthesized in various configurations depending on specific types of monomers and templates. Compared to conventional receptors such as antibodies and aptamers, MIPs exhibit outstanding advantages, including good stability, cost-effectiveness, ease of synthesis, reusability, and broad applicability. These advantages have led to their extensive application in biomedical healthcare devices. This review summarizes a comparative analysis of sensors utilized for the detection of disease-specific biomarkers through diverse MIP applications and methodologies. Furthermore, we evaluated recent advancements in the miniaturization of MIPs and their integration with wearable biomedical devices for comprehensive healthcare monitoring applications. Finally, we delineated the existing limitations that need to be surmounted for the effective implementation of MIP-based biomedical devices and outlined future objectives for the enhancement of wearable and wireless biomedical healthcare monitoring devices.

Despite that conventional polysomnography(PSG) is a very strong diagnostic tool for sleep disorders, there are some limitations. Among them, temporal and spatial limitations are very significant. They could be overcome by remotely-accessible digital PSG. We developed a digital PSG system for tele-monitoring patients overnight on physiological signals and behavior. The

In order to design a wave energy generating system of a floating type, a 6- Degrees Of Freedom (DOF) motion technique was applied to Computational Fluid Dynamics (CFD) analysis on this floating body and the behavior is interpreted according to the nature of the incoming waves. In the numerical study, the tuning factor concept is employed, as it explains the relation between the maximum pitch angle and the length of the floating body and wavelength. The relation between tuning factor & pitch period for the generated waves is compared to analyze the effects of wave energy absorption. Linear waves are generated in a tank model using a single floater. In this paper, we focus on wavelength of a floater and 14 cases have been modeled for the same. It was found that the wave energy absorption varies in different parameters of wavelengths and also the different locations of the floating body in a wave affect the wave energy absorption, thus necessitating the importance of the location of a floater in a wave and its effect on wave energy absorption.
