This article investigates the mixed H/H state estimation problem for a class of discrete-time switched complex networks with random coupling strengths through redundant communication channels. A sequence of random variables satisfying certain probability distributions is employed to describe the stochasticity of the coupling strengths. A redundant-channel-based data transmission mechanism is adopted to enhance the reliability of the transmission channel from the sensor to the estimator. The purpose of the addressed problem is to design a state estimator for each node, such that the error dynamics achieves both the stochastic stability (with probability 1) and the prespecified mixed H/H performance requirement. By using the switched system theory, an extensive stochastic analysis is carried out to derive the sufficient conditions ensuring the stochastic stability as well as the mixed H/H performance index. The desired state estimator is also parameterized by resorting to the solutions to certain convex optimization problems. A numerical example is provided to illustrate the validity of the proposed estimation scheme.

Objective: Machine learning (ML) may allow for improved discernment of hemodynamics and oxygen delivery compared to standard invasive monitoring. We hypothesized that an ML algorithm could predict impaired delivery of oxygen (IDO) with comparable discrimination to invasive mixed venous oxygen saturation (SvO) measurement.
Methods: A total of 230 patients not on mechanical circulatory support (MCS) managed with a pulmonary artery catheter (PAC) were identified from 1012 patients admitted to a single cardiovascular intensive care unit (CVICU) between April 2021 and January 2022.

Background Interest in microwave ablation (MWA) and radiofrequency ablation (RFA) use for treating secondary hyperparathyroidism (SHPT) is rising; however, ablation outcomes in patients with SHPT are not well characterized. Purpose To assess the response of parathyroid hormone (PTH), calcium, phosphorus, and alkaline phosphatase (ALP) levels to US-guided parathyroid MWA and RFA and the safety of these treatments in participants with SHPT. Materials and Methods This prospective multicenter cohort study, conducted from September 2017 to March 2022, included participants with SHPT.

In the capacitive mixing technique, the electrode used to extract blue energy is typically composed of a carbon-based porous electrode material. Polyelectrolyte (PE) surface coating on porous electrodes serves as an intermediate soft layer, which can significantly enhance the energy extraction performance (EEP). Herein, the blue energy extraction performance by using PE-coated electrodes is studied by a statistical thermodynamic theory, with the exploration of the interplay effects between opposing polyelectrolyte interactions and pore size.

A substantial fraction of nitrogen (N) fertilizer applied in agricultural systems is not incorporated into crops and moves below the rooting zone as nitrate (NO ). Understanding mechanisms for soil N retention below the rooting zone and leaching to groundwater is essential for our ability to track the fate of added N. We used dual stable isotopes of nitrate ( N-NO and O-NO ) and water ( O-HO and H-HO) to understand the mechanisms driving nitrate leaching at three depths (0.

Background And Objectives: Nicotinamide is a coenzyme involved in cellular oxidation-reduction reactions that can inhibit Class III histone deacetylases (HDACs) or sirtuins. HDAC inhibition can affect numerous therapeutic pathways, including tau phosphorylation. We tested the hypothesis that nicotinamide treatment could reduce tau phosphorylation in early Alzheimer disease (AD).
