Gbits/s-Level Encrypted Spectral Wireless Communication Enabled by High-Performance Flexible Organic Hyperspectrometer.

The exponential growth of data in the information era has pushed conventional optical communication technology to its limitations, including inefficient spectral utilization, slow data rate, and inherent security vulnerabilities. Here, a transformative high-speed organic spectral wireless communication (SWC) technology enabled by a flexible, miniaturized, and high-performance organic hyperspectrometer is proposed that integrates ultrahigh-speed data transmission with hardware-level encryption. By synergistically combining organic photodetector arrays with tunable responsivities and spectral-tunable organic filters, the organic hyperspectrometer achieves a broad spectral detection range of 400 to 900 nm, resolution of 1.

A DNA alteration and methylation co-detection method for clinical purpose.

Traditional approaches for capturing genomic alterations and DNA methylation require separate assays, complicating clinical workflows and limiting sample utilization, particularly with low-input materials like cell-free DNA. To address these challenges, we introduce a streamlined approach combining mutation and methylation profiling via mutation-protective strand synthesis with modified deoxycytidine triphosphates, demonstrating high concordance with standard enzymatic methyl-seq and DNA-seq in both whole-genome sequencing of cell lines and targeted sequencing of clinical samples. In potential clinical contexts, incorporating multi-omics information with this approach modestly improve circulating tumor DNA (ctDNA) detection by ~12% in pre-treatment lung cancer patients (N = 26) while preserving specificity in healthy controls (N = 13), and reveal relationships between homologous recombination repair (HRR) gene function and homologous recombination deficiency (HRD) mediated by promoter methylation-driven biallelic loss of HRR genes in gynecologic cancer patients (N = 27).

Investigation on Electromigration-Induced Failure and Reservoir Effect in AlCu Interconnects.

Aluminum-copper alloy (AlCu) is commonly utilized as interconnect material in low-power devices. However, as the size of electronic devices continues to decrease and current density increases, electromigration (EM) has emerged as a significant reliability concern for AlCu interconnects in the microelectronics industry. In this study, two-level AlCu interconnect structures with a Ti/TiN barrier layer were fabricated using 0.

Route-and-Aggregate Decentralized Federated Learning Under Communication Errors.

Decentralized federated learning (D-FL) allows clients to aggregate learning models locally, offering flexibility and scalability. Existing D-FL methods use gossip protocols, which are inefficient when not all nodes in the network are D-FL clients. This article puts forth a new D-FL strategy, termed route-and-aggregate (R&A) D-FL, where participating clients exchange models with their peers through established routes (as opposed to flooding) and adaptively normalize their aggregation coefficients to compensate for communication errors.

A cross-lagged panel network analysis of loneliness, internet use, and depression among Chinese college students.

Background: Displacement theory proposes that internet use can lead to heightened feelings of loneliness and depression, whereas the stimulation theory posits the opposite pathway. However, most investigations on this topic have been cross-sectional, precluding causal inferences. Thus, we used cross-lagged network analyses to facilitate causal inferences in understanding the relations between Internet use, loneliness and depression.

Pollution Characteristics of Heavy Metals in PM and Source-Specific Health Risks in the Tianjin Airport Community, China.

The airport and its surrounding areas are home to a variety of pollution sources, and air pollution is a recognized health concern for local populated regions. Submicron particulate matter (PM with an aerodynamic diameter of <1 mm) is a typical pollutant at airports, and the enrichment of heavy metals (HMs) in PM poses a great threat to human health. To comprehensively assess the source-specific health effects of PM-bound HMs in an airport community, PM filter samples were collected around the Tianjin Binhai International Airport for 12 h during the daytime and nighttime, both in the spring and summer, and 10 selected HMs (V, Cr, Mn, Co, Ni, Cu, Zn, As, Cd, and Pb) were analyzed.

Synthesis of novel nanoflowers-like P, K co-doped graphitic carbon nitride for efficient HO photoproduction.

Photocatalytic oxygen reduction is considered an economical and green way to produce HO. Graphitic carbon nitride is a common photocatalyst, but its activity is limited by the low specific surface area and the high recombination rate of photogenerated electron-hole pairs. Herein, nanoflowers-like phosphorus (P) and potassium (K) co-doped graphitic carbon nitride (PKCN) is synthesized by co-polymerization of ammonium dihydrogen phosphate and melamine in the mixed molten salt (KCl/LiCl) medium.
