Work in Progress: Use of Wood‐Based Inserts in Injection Molding

open access: yesEngineering Reports, Volume 8, Issue 3, March 2026.
The study investigates the suitability of wood‐based mold inserts for the production of small series in polymer injection molding, showing that specially modified materials like laminated beech and compressed bamboo are more promising than natural woods. The results indicate that reproducible components can be produced with these tools. ABSTRACT In the

MEASURING THE TIME DELAYS IN GRAVITATIONALLY LENSED QUASARS IN THE PRESENCE OF MICROLENSING

open access: yesRadio Physics and Radio Astronomy, 2014
A method to measure the time delays in gravitationally lensed quasars is proposed, which provides a simple and transparent procedure to eliminate the effects of microlensing events.

Anisotropy Analysis of Bamboo and Tooth Using 4‐Angle Polarization Micro‐Spectroscopy

open access: yesNano Select, Volume 7, Issue 3, March 2026.
Super‐resolution via orientation: spatial distribution of specific molecular vibrations are revealed at 1/20 of the diffraction limit. ABSTRACT To investigate the anisotropic properties of biomaterials, two distinct classes are considered as follows: polymer‐based (cellulose in plants) and crystalline‐based (enamel in teeth), each demonstrating ...

Volatile Fatty Acid Recovery from Arrested Anaerobic Digestion for the Production of Sustainable Aviation Fuel: A Review

open access: yesFermentation, 2023
The process of producing sustainable aviation fuel (SAF) from organic waste involves the use of volatile fatty acids (VFAs) as intermediates that are obtained via arrested anaerobic digestion (AAD) and VFA recovery.

Flame Retardant Polyolefins Using Fibers From Leather Waste: Adjusting Extrusion Variables to Balance the Property Profile

open access: yesJournal of Vinyl and Additive Technology, Volume 32, Issue 2, Page 410-430, March 2026.
Adjusting extrusion variables are a key to balance the flame retardancy and mechanical properties of polyolefin/leather waste fiber composites. ABSTRACT The extrusion processing variables represent a key to the optimal use of additives and thus the development of flame‐retardant polymer composites. Adjusting the property profile, for example, finding a

Automated quasar detection [PDF]

open access: yesMonthly Notices of the Royal Astronomical Society, 1983
The existing spectral searches for quasars have increased the number of quasars known very substantially but have not contributed proportionately to an understanding of the collective properties because of the selection effects. To fully exploit the spectral searches we have developed the technique of automated quasar detection (AQD) using objective ...

Characterization of the Nature of Organic Matter in Carbonate Rocks: Implications for Geological and Environmental Studies

open access: yesJournal of Geophysical Research: Biogeosciences, Volume 131, Issue 3, March 2026.
Abstract Organic matter in carbonate rocks plays a crucial role in processes such as fluid flow regulation, carbon sequestration, contaminant transport, and hydrocarbon recovery. This study employed multimodal spectroscopic techniques, including fluorescence imaging and Fourier transform infrared (FTIR) spectroscopy, to characterize the spatial ...

First Results from the JWST Early Release Science Program Q3D: Ionization Cone, Clumpy Star Formation, and Shocks in a z = 3 Extremely Red Quasar Host

open access: yesThe Astrophysical Journal, 2023
Massive galaxies formed most actively at redshifts z = 1–3 during the period known as “cosmic noon.” Here we present an emission-line study of the extremely red quasar SDSSJ165202.64+172852.3’s host galaxy at z = 2.94, based on observations with the Near

Acute metabolic responses to high‐intensity interval training in men with overweight or obesity: Does the exercise modality matter?

open access: yesExperimental Physiology, Volume 111, Issue 3, Page 904-915, 1 March 2026.
Abstract This study investigated the acute effects of two isoenergetic high‐intensity interval exercise (HIIE) sessions, running (HIIE‐RUN) and cycling (HIIE‐BIKE), on post‐exercise oxygen consumption (V̇O2${\dot V_{{{\mathrm{O}}_2}}}$), carbon dioxide production (V̇CO2${\dot V_{{\mathrm{C}}{{\mathrm{O}}_2}}}$), substrate oxidation and 24‐h energy ...

Search for quasar pairs with Gaia astrometric data

open access: yesAstronomy & Astrophysics
Quasar pairs, a special subclass of galaxy pairs, are valuable in the investigation of quasar interaction and clustering, the coevolution between the two quasars’ host galaxies, and the growth of supermassive black holes, as well as the formation and ...
