Surrogate-assisted global and distributed local collaborative optimization algorithm for expensive constrained optimization problems.
Sci Rep

This paper presents a surrogate-assisted global and distributed local collaborative optimization (SGDLCO) algorithm for expensive constrained optimization problems where two surrogate optimization phases are executed collaboratively at each generation. As the complexity of optimization problems and the cost of solutions increase in practical applications, how to efficiently solve expensive constrained optimization problems with limited computational resources has become an important area of research. Traditional optimization algorithms often struggle to balance the efficiency of global and local searches, especially when dealing with high-dimensional and complex constraint conditions.

Starch spherulite is a unique form of resistant starch characterized by a spherical structure with crystalline lamellae that are radially oriented and may find applications in delivery of nutrients and bioactives to the lower gastrointestinal tract. Formation of starch spherulites generally requires heating to a high temperature followed by quenching and long crystallization time. The objectives of this study were to gain a deeper understanding of the factors influencing spherulite formation from pea starch (PS) and high-amylose maize starch (HAMS) and investigate if spherulites could be formed by a slow cooling rate and determine the crystalline structure and morphology of the spherulites formed.

Electroplating sludge (ES) is a hazardous waste, because it contains heavy metals. It poses severe environmental and health risk if not properly disposed. This study proposed a combined pyro-metallurgical process to separate and recover copper, nickel, chromium and iron from it.

Background And Aims: Ward-delivered non-invasive respiratory supports (NIRS) (conventional oxygen therapy (COT), high-flow nasal oxygen (HFNO), continuous positive airway pressure (CPAP) and non-invasive ventilation (NIV)), are often used to treat hospitalised patients with acute respiratory failure (ARF) both in high acuity and general wards. This study aimed to describe the processes of care adopted and examine patient outcomes from a specialist, ward-delivered NIRS service caring for people with COVID-19 in general wards or in a respiratory care unit (RCU).
Methods: A cohort study was undertaken including all consecutive patients admitted to a quaternary hospital with ARF secondary to COVID-19 and requiring ward-delivered NIRS between 28 February 2020 and 18 March 2022.
Effects of Automated Versus Conventional Ventilation on Quality of Oxygenation-A Substudy of a Randomized Crossover Clinical Trial.

: Attaining adequate oxygenation in critically ill patients undergoing invasive ventilation necessitates intense monitoring through pulse oximetry (SpO) and frequent manual adjustments of ventilator settings like the fraction of inspired oxygen (FiO) and the level of positive end-expiratory pressure (PEEP). Our aim was to compare the quality of oxygenation with the use of automated ventilation provided by INTELLiVENT-Adaptive Support Ventilation (ASV) vs. ventilation that is not automated, i.
