Study on Programmable Optical Frequency Multiplication and Optical Frequency Comb Generation Methods

Guangtongxin yanjiu
ObjectiveConventional millimeter-wave mobile forward transmission systems usually utilize electronic devices to realize signal generation and processing, with their frequency bands and bandwidths limited by the “electronic bottleneck”.

Phylogenomic analysis of ultraconserved elements clarifies relationships and morphological evolution in Cryptoplacoidea (Mollusca: Polyplacophora)

Cladistics, EarlyView.
Abstract Targeted enrichment of ultraconserved elements (UCEs) is a powerful tool for resolving phylogeny in groups with limited morphological or molecular data. Here, we use UCEs to reconstruct the first comprehensive phylogeny of the chiton superfamily Cryptoplacoidea, including museum material up to 133 years old.

Unravelling the phylogeny of armadillos and their kin (Mammalia, Xenarthra, Cingulata) combining morphological, molecular, and stratigraphic data

Cladistics, EarlyView.
Abstract Cingulata, a major lineage of Xenarthra, comprises extinct and extant armoured placental mammals that diversified throughout the Cenozoic. Despite extensive study, phylogenetic hypotheses based on morphological and molecular data remain incongruent, and no total evidence analysis has been conducted. Here, we integrate the largest morphological

A revised classification system of the marronoid clade of spiders (Araneae), based on dense sampling phylogenomics and comparative morphology

Cladistics, EarlyView.
Abstract The marronoid clade is a globally distributed, ecologically diverse group of spiders. It is an important faunal component in both natural and synanthropic environments, and even found in aquatic and extreme habitats such as desert salt flats. The systematics of the marronoid clade has been notoriously unstable due to the widespread character ...

Occupational Exposure to Nickel and Cobalt From Hairdressing Tools: A Cross‐Sectional Study in 58 Danish Salons

Contact Dermatitis, EarlyView.
Spot testing of 266 metallic tools across 58 Danish hair salons revealed that 13.9% released nickel and 6.8% released cobalt. This ongoing occupational exposure during routine wet work highlights the urgent need for safer tool materials and stricter regulatory oversight to protect hairdressers.

Appraisal of Six Natural Mica Reference Materials for In Situ Rb‐Sr Geochronology

Geostandards and Geoanalytical Research, EarlyView.
Key Points Evaluated six natural mica reference materials for in situ LA‐ICP‐MS/MS Rb‐Sr geochronology using geochemical, microstructural and isotopic characterisation. Identified robust primary reference materials: Mount Dromedary biotite (99.37 Ma) and Mica‐Fe biotite (307.75 Ma). La Posta biotite and Högsbo muscovite are suitable secondary reference

Clinical improvement and scalp microbiome restructuring following a 28‐day piroctone olamine shampoo intervention

International Journal of Cosmetic Science, EarlyView.
A 28‐day clinical study in 41 individuals with oily dandruff showed that a piroctone olamine shampoo improved clinical symptoms while selectively reshaping the scalp bacterial and fungal microbiome toward a less dysbiotic profile. Abstract Objective To evaluate the clinical efficacy of a piroctone olamine–containing shampoo in individuals with oily ...

The effects of playbacks of anthropogenic noise on the anti‐predator behaviour of Pacific sand lance, Ammodytes personatus

Journal of Fish Biology, EarlyView.
Abstract Noise from human activities has increased and been shown to negatively impact marine animals. Marine mammals and fish are vulnerable to anthropogenic noise because they rely on sound to communicate, find food, avoid predators and sense their environment. Forage fish are small schooling pelagic fish, important to many predators and instrumental
