Genetic Diversification in a New Guinean Frog Genus (Mantophryne, Microhylidae) was Driven by Ancient Tectonic Activity and Climate Reorganisation

Ecology and Evolution, Volume 16, Issue 5, May 2026.
Our dated phylogeny and biogeographic analysis of Mantophryne, a microhylid frog genus endemic to New Guinea, revealed origins in the East Papuan Composite Terrane (EPCT) in the late Pliocene. Dispersal and diversification out from the EPCT was driven by tectonic activity and climate reorganisation, creating habitat corridors and isolations in the Late

Influence of Manganese Dioxide (MnO2) Coated Oil Palm Empty Fruit Bunch Spikelet Fibers on the Physicochemical and Mechanical Properties of Fiber Cement Composites

Engineering Reports, Volume 8, Issue 5, May 2026.
MnO2‐coated OPEFB fibers produced via a simple wet process showed smoother surfaces and significantly reduced water absorption in fiber cement composites, enhancing moisture resistance. ABSTRACT The use of natural fibers in cement‐based composites is increasingly encouraged as a sustainable alternative to synthetic fibers; however, their inherent ...

Predictive Multiphysics Modeling of Corrosion Behavior and Passive Layer Formation in Hydroxyapatite‐Coated Titanium Implants

Engineering Reports, Volume 8, Issue 5, May 2026.
A multiphysics finite element model predicts the long‐term corrosion behavior of hydroxyapatite–ionic liquid coatings on Ti‐6Al‐4V implants in simulated body fluid. Simulations reveal precipitation‐driven Ca–P passive layer growth that suppresses chloride transport, reduces corrosion current by over two orders of magnitude, and significantly enhances ...

Monolithic Integration of ScAlN Modulators on Silicon‐On‐Insulator Platform

Laser &Photonics Reviews, Volume 20, Issue 9, 6 May 2026.
Monolithic integration of scandium‐doped aluminum nitride (ScAlN) modulators on a silicon‐on‐insulator platform is reported. A multilayer electrode design enhances RF‐optical field overlap, enabling direct access to the diagonal electro‐optic coefficient and improved modulation efficiency.

Absolute scaling of small‐ and wide‐angle X‐ray scattering images recorded with short duration X‐ray pulses on a large area fiber‐taper X‐ray detector

Journal of Synchrotron Radiation, Volume 33, Issue 3, Page 562-579, May 2026.
An X‐ray scattering setup designed to capture small‐ and wide‐angle X‐ray scattering on a single, large area detector features a partially transmissive beamstop that facilitates non‐invasive recording of X‐ray beam position and intensity during acquisition of X‐ray scattering images.

Monitoring Biogenic Amines: Comparative Assessment of Detection Methods for Key Market Marine and Freshwater Species

Journal of Food Science, Volume 91, Issue 5, May 2026.
ABSTRACT Biogenic amines, primarily histamine, cadaverine, and putrescine, are important indicators of microbial spoilage and potential health risks. This review summarizes established and novel analytical methods for quantitatively determining biogenic amines in fish and fish products, along with their limits of detection in these complex matrices ...

Physicochemical and Thermal Evaluation of a Mixed‐Mode Greenhouse Solar Dryer for Guava (Psidium guajava L.)

Journal of Food Science, Volume 91, Issue 5, May 2026.
ABSTRACT The present study aimed to evaluate the quality and nutritional properties of guava slices dried in a greenhouse solar dryer (operated under mixed and direct modes) and an electric stove at 50°C. The results showed that mixed‐mode solar drying resulted in greater retention of vitamin C (112.60 mg/100 g), carotenoids (0.37 mg/g), and ...

Design Rules for Carboborothermic Reduction Synthesis of High Uranium Density UB4–UBC Composites

Journal of the American Ceramic Society, Volume 109, Issue 5, May 2026.
ABSTRACT Uranium borides are promising candidate fuel forms for use in advanced nuclear reactors due to their high thermal conductivity and potential for dual use as both fuel and burnable absorber. In this work, uranium tetraboride (UB4${\rm UB}_4$) and uranium monoboroncarbide (UBC) composite were synthesized by using industrially scalable ...

Critical cladding radius for hybrid cladding modes

Optics & Laser Technology, 2018
Abstract In this article we explore some properties of the cladding modes guided by a step-index optical fiber. We show that the hybrid modes can be grouped by pairs and that it exists a critical cladding radius for which the modes of a pair share the same electromagnetic structure. We propose a robust method to determine the critical cladding radius
