This paper presents a novel approach to economic dispatch (ED) optimization in power systems through the application of Proximal Policy Optimization (PPO), an advanced reinforcement learning algorithm. The economic dispatch problem, a fundamental challenge in power system operations, involves optimizing the generation output of multiple units to minimize operational costs while satisfying load dem

We introduce lower-bound certificates for classical planning tasks, which can be used to prove the unsolvability of a task or the optimality of a plan in a way that can be verified by an independent third party. We describe a general framework for generating lower-bound certificates based on pseudo-Boolean constraints, which is agnostic to the planning algorithm used. As a case study, we show how

Employing the term “green nationalism” in the broad sense of nationalist ideologies that concern themselves with the natural environment, we trace a genealogy of green nationalist thought in Japan back to the start of the long 19th century. The changing contours of this discourse are mapped through five representative writers: Moto'ori Norinaga (1730–1801), Shigetaka Shiga (1863–1927). Testurō Wat

Single-nucleus RNA sequencing enables high-resolution transcriptomic profiling of brain tissue, facilitating analysis of cell identity in models of neurodegeneration and repair. Here, we present a protocol for isolating nuclei from long-term human stem cell-derived grafts in the rat brain. We describe steps for vibratome sectioning, graft dissection, nuclear extraction, and fluorescence-activated

Multi-hazard events, though infrequent and rare, are responsible for a substantial portion of global economic losses. This book chapter investigates the complexities of multi-hazard events and explores the design challenges and methodologies in multi-hazard risk assessment and structural resilience for wooden structures. Special attention is given to the interaction between earthquakes, fires, and

The aggregation of tau into amyloid fibrils is associated with Alzheimer’s disease (AD) and related tauopathies. Since different tauopathies are characterized by the formation of distinct tau fibril morphologies, it is important to combine the search of tau aggregation inhibitors with the development of in vitro tau aggregation assays that recapitulate aggregation as it may occur in the brain. Her

High-resolution transmission spectroscopy has become a powerful tool for detecting atomic and ionic species in the atmospheres of ultra-hot Jupiters. In this study, we demonstrate for the first time that the Australian-built Veloce spectrograph on the 3.9-m Anglo-Australian Telescope can resolve atmospheric signatures from transiting exoplanets. We observed a single transit of the ultra-hot Jupite

The presence of lipids after pea protein isolation was related to changes in protein structure and functionality. The aim of this study is to investigate the effects of the presence of lipids, specifically polar endogenous lipids (phospholipids), on pea globulins' (including legumin and vicilin) structure and functionality. Pea globulins were extracted by isoelectric precipitation from defatted an

Therapeutic proteins are essential in modern medicine but are often susceptible to chemical degradation during production, transportation, and storage, which can compromise functionality and even lead to immunogenicity in patients. This study investigates how the structure of the affibody GA-Z affects its chemical stability and how glycerol stabilizes the protein against deamidation and isomerizat

This study investigates the surface transformations of nickel foam (NF) electrodes induced by Fe and Co cation incorporation from the electrolyte following activation in the oxygen evolution reaction (OER), using both ex situ time-of-flight secondary ion mass spectrometry (TOF-SIMS) and in situ near-ambient pressure X-ray photoelectron spectroscopy (NAP-XPS). Electrochemical measurements demonstra

Philanthropy for gender causes is recognised as a rising yet understudied phenomenon, especially in the field of social policy. This chapter provides an overview of key interdisciplinary feminist debates on the philanthropic turn to gender equality and women's empowerment. It also presents significant trends, including funding flows towards SDG5, key actors, and geographical areas of investment, a

Cell staining techniques are essential for cell visualization and bioanalysis, providing valuable insights into cellular structure, function, and behavior. Despite their significance, the impact of staining processes, such as dye penetration, adsorption, or hydrogen bonding, on the physical properties of cells remains largely unexplored. Acoustic methods have proven effective in noninvasively prob

This special issue deals with temporalities in migration law with particular emphasis on the European context. At the crossroads of several legal fields, including public law, human rights law, EU law and public international law, the topic is cutting-edge in migration law. The articles collected were originally presented at a conference organized at Vrije Universiteit in Amsterdam in June 2023 an

In this study, a serial production system consisting of two machines and an intermediate finite buffer is considered. The machines have random processing times, and each machine contains one unit of a common critical component that is subject to random breakdown. Broken components must be replaced from an inventory of ready-for-use spare parts to restore machine functionality. This inventory is re

Marine megafauna species are affected by a wide range of anthropogenic threats. To evaluate the risk of such threats, species' vulnerability to each threat must first be determined. We build on the existing threats classification scheme and ranking system of the International Union for Conservation of Nature (IUCN) Red List of Threatened Species by assessing the vulnerability of 256 marine megafau

In this forum, seven scholars discuss Oliver P. Richmond’s The Grand Design: The Evolution of the International Peace Architecture, published in 2022. The editors, Gëzim Visoka and Annika Björkdahl, contextualise the book’s contribution within the broader intellectual framework of Richmond’s thoughts and writings on peace in the context of International Relations. Roland Bleiker examines the book’
