In power system restoration (PSR), networks with various voltage levels have different decision-making constraints and restoration characteristics. Specifically, the restoration plan for the lower voltage level network is more adaptable to uncertainty of wind power output, owing to its greater flexibility. First, the restoration scheme decision-making is divided into two parts for the main network level (MNL) and the regional network level (RNL) respectively, according to the voltage levels. Second, a hierarchical coordinated optimisation model is established based on a two-stage framework. In the first stage, the plants/lines restoration sequence of the MNL and the subsystem partitioning scheme are determined. Furthermore, the plants/lines restoration sequence of the RNL and the restoration power scheduling scheme of the MNL and RNL are obtained in the second stage of optimisation, which can be flexibly adjusted to adapt to uncertain wind power outputs. The coordination and allocation of frequency regulation resources across subsystems are considered. Finally, the nested column and constraint generation algorithm is applied to solve the two-stage robust model. Case studies using the IEEE standard and a provincial system in China show that the algorithm converges in 2–3 iterations. Compared to non-hierarchical approaches, the proposed method improves cumulative restored energy by 2% and 5.3% in case 1 and case 2, respectively, while maintaining robustness against wind power uncertainty, highlighting its effectiveness in multi-level PSR.

Private set intersection (PSI) is a privacy-preserving scheme that computes the intersection of two datasets without leaking any other information. Additionally, there is multiparty private set intersection (MPSI) to extend the number of parties for computing the intersection of multiple private datasets. In the traditional PSI and MPSI studies, protocol parties input their private datasets, and one or all of them can compute the intersection. However, there are some scenarios where an inputless external party requires the intersection between private datasets of other parties. Thus, the external party PSI protocols have been recently studied for applications such as pandemic contact tracing, computing human genome information and evaluating policy effects. However, they are limited in applications because the external party can compute the intersection of two datasets. In this paper, we propose a new external party compute-MPSI (EPC-MPSI) protocols that allow an external party to compute the intersection of multiple datasets. We provide the extension of the number of parties and solve the limitation of prior external party PSI protocols. In addition, we analyze the correctness, security and the efficiency in terms of communication and computation costs compared to the prior traditional MPSI protocols.

Nanostructured Transition Metal Oxides

In article number 2418407, Hyun Ho Kim and co-workers present a universal and ultrafast method for synthesizing nanostructured transition metal oxides (NTMOs) through the induced solidification of microdroplets, enabling rapid production within a minute. Since NTMOs can be directly grown on substrates in ambient air without requiring high-purity carrier gases, this approach facilitates industrial-friendly mass production.

In the ‘Material and Methods’ section and in the ‘Results’ section, the assertation that the distribution of the residual errors followed a normal distribution was unnecessary to assess model validity. This may lead to some confusion about the family of distribution that was used. As stated in the article, we relied on the binomial distribution.

We apologize for this mistake.

Programmable Bio-Inspired Magnetic Heart Valve System

Soft magnetic valve (SMV) system introduces a miniaturized, biomimetic magnetic heart valve inspired by the human aortic valve, designed for precise cardiovascular simulations. The valve, composed of a silicone elastomer embedded with neodymium magnetic micro-particles, responds dynamically to controlled magnetic fields generated by electromagnets. This programmable system replicates diverse blood pressure waveforms by regulating fluid flow and pressure with high accuracy. With a compact and versatile design, the artificial valve system offers potential applications in clinical trials, biomimetic robotics, and advanced biomedical research. More details can be found in article number 2419504 by Jeongmin Yoo, Gooyoon Chung, and Yoonseok Park.

This study explores the innovative synthesis and versatile applications of Ca₅(PO₄)₃F@Ca₅P₈ nanocomposites (NCs), crafted from phosphate waste sourced from Djebel Onk, Algeria, advancing sustainable material use and environmental remediation. FTIR analysis unveiled distinct functional groups, including C─H, P─H, P─O, and F─Ca, underscoring the material's chemical richness, while XRD revealed a crystalline architecture blending hexagonal (Ca₅(PO₄)₃F) and monoclinic (Ca₅P₈) phases, with a precise crystallite size of 22.45 ± 1.18 nm. SEM and EDS showcased uniform spherical particles averaging 24 nm, brimming with Ca, P, O, and F elements. Optical properties dazzled with peak absorption at 391 nm, direct and indirect bandgaps of 1.62 and 2.98 eV, and an Urbach energy of 0.435 eV, signaling exceptional UV–visible absorption capabilities. Beyond its structural elegance, the nanocomposite exhibited remarkable antioxidant prowess, neutralizing nearly 100% of hydrogen peroxide, and delivered striking photocatalytic performance, degrading 99.2% of Evans Blue dye in just 140 min (rate constant 0.01334 min⁻¹). Antibacterial assays further highlighted its potency, effectively combating S. aureus, C. albicans, and other microbes. These compelling results position Ca₅(PO₄)₃F@Ca₅P₈ NCs as a multifunctional powerhouse for water treatment, photocatalysis, and antibacterial applications, paving the way for sustainable technological breakthroughs.
