In the present work critical importance and benefits of Super Refined excipients for drug stability, integrity and safety are described. It was shown, that impurities can disrupt API and cause cell irritation. It was proved, that chromatographically purified excipients are fundamental to develop eff...

Topographic modeling using orbital imagery is a cornerstone of planetary photogrammetry and remote sensing, underpinning scientific exploration and analysis. While classical methods like stereo-photogrammetry (SPG) and (stereo)-photoclinometry (SPC) have long been developed, deep learning (DL) techn...

This review covers the issues related to the application of radial free forearm flaps for the reconstruction of defects after surgeries for oral squamous cell carcinoma. The advantages of this method include optimal match of the flap to the tissues of the oral cavity, good adaptation to defect edges...

This paper investigates the use of a dual wavelength laser source, a frequency shifter, an erbium-doped fiber amplifier, and an optical filter to compose a multiwavelength fiber laser (MWFL) with an ultranarrow wavelength spacing. The frequency shifter can be achieved by modulating an optical carrie...

Change detection reveals the shifts in land-use distribution and composition over time, providing valuable insights for urban management and socioeconomic analysis. Previous studies have focused primarily on single-modal data like high-resolution remote sensing (RS) imagery, overlooking the role of...

The improvement of flame-retardant properties of polyamide 6 (PA6) was achieved by using reduced graphene oxide decorated with halloysite nanotubes (HNTs-d-rGO) hybrid composite as the additive in PA6 matrix. The intimate integration of reduced graphene oxide (rGO) and halloysite nanotubes (HNTs) th...

We demonstrate the codesign and cointegration of an ultracompact silicon photonic receiver and a low-power-consumption (155 mW/channel) two-channel linear transimpedance amplifier array. Operation below the forward error coding (FEC) threshold both for quadrature phase-shift keying (QPSK) and 16-qua...
