This article investigates the problem of dynamic event-triggered finite-time H state estimation for a class of discrete-time nonlinear two-time-scale Markov jump complex networks. A hybrid adjusting variables-dependent dynamic event-triggered mechanism (DETM) is proposed to regulate the releases of measurement outputs of a node to a remote state estimator. Such a DETM contains both an additive dynamically adjusting variable (DAV) and a multiplicative adaptively adjusting variable. The aim is to design a DETM-based mode-dependent state estimator, which guarantees that the resultant error dynamics is stochastically finite-time bounded with H performance. By constructing a mode-dependent Lyapunov function with multiple DAVs and a singular perturbation parameter associated with time scales, a matrix-inequalities-based sufficient condition is derived, the feasible solutions of which facilitate the design of the parameters of the state estimator. The validity of the designed state estimator and the superiority of the devised DETM are verified by two examples. It is verified that the devised DETM is capable of saving network resources and simultaneously improving the estimation performance.

Introduction: COVID-19 has caused tremendous hardships and challenges around the globe. Due to the prevalence of asymptomatic and pre-symptomatic carriers, relying solely on disease testing to screen for infections is not entirely reliable, which may affect the accuracy of predictions about the pandemic trends. This study is dedicated to developing a predictive model aimed at estimating of the dynamics of COVID-19 at an early stage based on wastewater data, to assist in establishing an effective early warning system for disease control.

Background: Abortion-related complications are difficult to measure due to lack of standardized definitions and limited available data. We describe the proportion of abortive events that result in a documented complication in Mexico's public sector hospitals.
Methods: We used ICD-10 codes from Mexico's hospital discharge system (2018-2022), Subsistema Automatizado de Egresos Hospitalarios (SAEH), to describe abortive events admitted to hospitals: complications for excessive bleeding, infection, embolism, and unspecified; patient socio-demographic and clinical characteristics; and municipality-level structural vulnerability.
Dual-Response UV Radiation Detector Based on Color Switching and Photoresistance Response for UV Radiation Monitoring.

Ultraviolet (UV) irradiation is dangerous and can cause serious skin diseases if skin is excessively exposed to it. Thus, it is highly desirable for human health to monitor the UV radiation intensity. In this report, a flexible and stretchable dual-response UV radiation detector is reported by integrating UV-responsive color-switchable WO quantum dots (QDs) with an electrical hydrogel.

The study quantitatively analyzes and compares the pharmacokinetics (PK) of methylprednisolone (MPL) in humans upon administration of various dosage forms. The PK parameters and profiles of MPL in healthy subjects were collected from 22 literature sources. A minimal physiologically based pharmacokinetic (mPBPK) model consisting of blood and two tissue (lumped liver and kidney, remainder) compartments with nonlinear tissue partitioning was applied to describe MPL disposition.

Antiretroviral therapy (ART) use and HIV suppression among people living with HIV (PLHIV) are critical for HIV control and prevention. Extreme restrictions on movement early during the COVID-19 pandemic in Uganda may have impeded the ability to initiate and sustain access to and use of ART. From our stepped-wedge cluster-randomized trial of an integrated PrEP and ART intervention for HIV-serodifferent couples at 12 ART clinics in Uganda, we identified participants who enrolled and had a 6-month post-ART initiation viral load measured before the beginning of the first COVID-19 lockdown (Period 1), participants whose enrollment and 6-month viral load measurement straddled pre-COVID and COVID lockdown times (Period 2), and participants whose enrollment and 6-month viral load were quantified entirely during COVID-19 (Period 3).
