Summary: This study identified various barriers to hypertension treatment and control in Nepal, including health system, health provider, and patient-related factors. Comprehensive interventions are needed at all three levels to further improve the management and control of hypertension in Nepal.

Summary: This study aimed to describe the disparities in the prevalence and barriers to hypertension control across countries of various income categories. The findings showed differences in the prevalence of hypertension control between low and middle-income countries (3.8% to 50.4%) and high-income countries (36.3% to 69.6%). The most frequently reported barriers were patient-related, followed by medication adherence and lifestyle-related barriers.

Summary: The purpose of this review is to examine the barriers and opportunities associated with racial and ethnic disparities in blood pressure control. Recent findings show that blood pressure control rates in the USA have worsened, particularly among racial and ethnic minority groups. Factors such as health literacy, socioeconomic status, access to healthcare, awareness rates, and dietary habits contribute to these disparities. Various interventions, such as dietary programs, faith-based interventions, and community-based programs, have shown success in reducing these disparities.

Summary: This paper studies the optimal design and control scheme of a spoke-type interior permanent magnet motor (SIPM). An asymmetric rotor structure with flux barriers is designed to improve the torque density of SIPM. The design method improves the torque density by approximating the maximum value of the magnetic torque and the reluctance torque, wherein the torque components are separated by the frozen permeability method (FPM) to evaluate the contribution. This scheme does not increase the amount of permanent magnets or the motor size, and reduces motor weight while increasing motor torque output.

Summary: We propose a novel particle filtering framework for continuous-time dynamical systems with continuous-time measurements. The framework is based on the duality between estimation and optimal control, which allows formulating the estimation problem as an optimal control problem over a fixed time window. By recursively solving these optimal control problems approximately, an optimal control based particle filtering algorithm, termed the path integrals particle filter (PIPF), is obtained. The proposed method uses measurements over a finite-length time window instead of a single measurement for estimation, resembling batch methods of filtering and improving fault tolerance. Several numerical examples demonstrate the efficacy of the algorithm.

Summary: Hypertension is linked to immune and lymphatic system activation as well as lymphangiogenesis. Renal lymphangiogenesis has been shown to effectively reduce systemic arterial blood pressure in hypertensive mice. This article provides a review of the relationship between immune and lymphatic system activation and its impact on systemic blood pressure, summarizes the findings of Goodlett and collaborators, and discusses the implications of their findings.

Summary: This research demonstrates that an integral-equation-based formulation of conservation laws in quantum dynamics provides a systematic framework for identifying fundamental limits to any quantum control scenario. The study shows the tightness of these bounds in different scenarios, providing guidance for designing performance levels. Global bounds complement local optimization designs, highlighting both achievable performance levels and limits that cannot be surpassed.

Summary: This study aimed to determine the facilitators and barriers experienced by patients with hypertension in telemonitoring of blood pressure (BP) using the electronic health literacy framework. The results identified five themes and 28 subthemes that influence BP telemonitoring. The findings showed concordance and discordance between participants' e-HL status and their experiences in actively engaging with BP monitoring.

Summary: In this paper, a new method is proposed for controlling surface water waves and their interaction with floating bodies. Three control strategies are designed, of increasing complexity, for a floating target rigid body. The performance of an additional controlled floating device, modeled as a membrane or a thin plate, is analyzed. The problem is framed as an optimal control problem, aiming to minimize unwanted motions of the floating body. Numerical simulations demonstrate the efficacy of this new method for reducing hydrodynamic loads on floating objects.

Summary: This article proposes a scheme for the analysis and control design of a back-to-back (BTB) converter using a multivariable approach. The BTB converter is analyzed as a multiple-input multiple-output system using singular value decomposition and relative gain array, which helps determine the variables that should be controlled within a given frequency range. Based on this analysis, low- and high-frequency controllers are included to track references and reject disturbances. The sensitivity and complementary sensitivity functions are analyzed to fine-tune a centralized optimal linear quadratic multivariable control. Experimental results are presented to validate the effectiveness of the analysis and control design.

Summary: Permeable concrete, as a material for controlling water pollution, has been widely applied in low-impact development practices and has shown efficiency in mitigating the environmental impacts of urbanization. It can be used as a permeable reactive barrier to remediate groundwater and treat acid mine drainage. The current research focuses on material selection, mix design, and characterization techniques to evaluate the performance of permeable concrete. However, further research is needed to optimize the design of concrete barriers and minimize their environmental impacts.

Summary: The study found that lowering the threshold of tricuspid regurgitation velocity to approximately 2.7 m/s can effectively screen for pulmonary hypertension with high sensitivity in tertiary referral centers. Right heart chamber measurements were also found to improve the diagnostic yield of echocardiography.

Summary: In the absence of drugs and vaccines, societies use non-pharmaceutical interventions such as social distancing to reduce disease transmission rates, aiming to decrease or delay the epidemic peak. Policy design relies on numerical simulations, but implementation errors can lead to significant increases in peak prevalence.

Summary: Essential hypertension is a major factor in cardiovascular mortality worldwide, but its pathophysiology is not fully understood. The immune system has been identified as an important part of the pathogenesis of arterial hypertension. Recent publications have focused on the interplay between different components of the immune system and mechanisms of arterial hypertension, contributing to our understanding of the role of immunity and inflammation in the disease's pathogenesis.

Summary: The study found that hypertension control in the United States plateaued from 2009 to 2010, then declined from 2015 to 2018. Despite unchanged access to healthcare, awareness, treatment, and treatment effectiveness for hypertension all decreased. Hypertension control fell across different age and race-ethnicity groups.
