An unusual new cicadellid genus, Ulopsina gen. nov. and two new species, U. sinica sp. nov. and U. szwedoi sp. nov. from China are described, illustrated, and placed in the subfamily Ulopinae. The genus has characters of both the tribes Mesargini and Coloborrhinini, suggesting that the delimitation of these tribes may not be natural. The tribal placement of Ulopsina is uncertain. A checklist of...

This paper presents a micro XY stage that employs electrostatic comb-drive actuators and achieves a bi-directional displacement range greater than 225 μm per motion axis. The proposed XY stage design comprises four rigid stages (ground, motion stage, and two intermediate stages) interconnected via flexure modules. The motion stage, which has two translational degrees of freedom, is connected to...

Beeswax foundations are a necessary material in intensive modern beekeeping. Heavy metals can accumulate in these foundations for decades, as it is a common beekeeping practice to recycle wax. Beeswax samples were analysed using GFAAS for As, Cd, Pb, and Hg concentrations during the production of beeswax foundations using casting technology with a prolonged cooling and sedimentation phase. Sign...

A new subgenus and species, Charidotella (Chapadacassis subgen. n.) paradoxasp. n. is described and figured from the Chapada plateau in Mato Grosso, Brazil. Subgenera of Charidotella Weise, 1896 are listed, supplemented with basic data, diagnostic table, and a key is proposed. Based on a study of respective type material following new combinations are proposed: Charidotella (Philaspis) stulta (...

Experiments and theoretical modelling yielded significant progress toward understanding of Kerr-effect induced optical frequency comb generation in microresonators. However, the simultaneous Kerr-mediated interaction of hundreds or thousands of optical comb frequencies with the same number of resonator modes leads to complicated nonlinear dynamics that are far from fully understood. An importan...

The paper represents the first part of a series dealing with the Eastern Hemisphere species of the genus Polymerus Hahn, 1831 and includes a redescription of the genus and the nominative subgenus, and descriptions of Pachycentrum subgen. nov., P. (Polymerus) russatus sp. nov. and P. (Pachycentrum) unciniger sp. nov. The specific name P. funestus Reuter, 1906 is transferred from the subgenus Poe...

In Indonesia, one of the sources regional livestock genetic diversity is kampung chicken. This study aimed to assess development and reproductive potential F1 Kampung Unggul Balitbangtan (KUB) crosses (KUB roosters with different types combs crossed layer chickens). research was conducted at a private chicken company in Gunungkidul regency using 40 KUB 320 chicks. The were separated into four g...

Axylus group is used to include the five genera Axylus Stål, 1877, Anthracites Redtenbacher, 1891 sensu stricto, Eucoptaspis Willemse, 1966, Eulobaspis gen. nov., and Heminicsara Karny, 1912. It is mainly based on a combination of the characters shape of pronotum, spiniform meso- and metasternal lobes, and similar basic ground plans of the male cerci, titillators and female subgenital plates. T...

Microresonator-based frequency comb generation at or near visible wavelengths would enable applications in precise optical clocks, frequency metrology, and biomedical imaging. Comb generation in the visible has been limited by strong material dispersion and loss at short wavelengths, and only very narrowband comb generation has reached below 800 nm. We use the second-order optical nonlinearity ...
