Summary: This study systematically investigated the vibrational characteristics of sapphire under temperature variation using Raman scattering measurements. The results revealed the linear temperature dependence of phonon mode frequencies at high temperatures and provided corresponding temperature coefficients. Additionally, the study quantified the frequency downshift and linewidth broadening in strain-free sapphire and applied a theoretical model to analyze these phenomena. The findings can contribute to a deeper understanding of the behavior of optical phonons in sapphire and have potential applications in other materials.

Summary: Lead telluride (PbTe), a narrow bandgap semiconductor commonly used in infrared detectors, exhibits unique vibrational and structural properties suitable for thermoelectrics. This study reveals that the unusual phononic properties in PbTe can be tuned via photoexcitation, enabling new optical functionalities in THz applications, such as spectrally tunable emitters and all-optical modulators. Additionally, a spectrally tunable THz emission peak with significant tunability has been achieved in PbTe.

Summary: ε γ δ β thalassemia is a rare form of beta-thalassemia, mostly seen in children from Northern Europe. This case report describes a newborn from Italy who presented with severe neonatal anemia and required red blood cell transfusion. After excluding other red blood cell disorders, the diagnosis of ε γ δ β thalassemia was made based on microarray analysis showing a 26 kb single copy loss of chromosome 11p15.4.

Summary: The contribution of optical phonons in complex structural low thermal conductivity oxides, especially in La2Zr2O7, was found to be significant. As structural complexity increases, the contribution of optical phonons becomes more pronounced. This highlights the importance of considering optical phonon contributions in understanding lattice thermal conductivity in crystalline materials.

Summary: CK1 delta/epsilon enhance beta-catenin-mediated transcription by regulating beta-catenin acetylation. CK1 delta/epsilon interact with Tip60 and facilitate its recruitment to the beta-catenin complex, leading to increased beta-catenin acetylation at K49. Furthermore, this study discovers that a complex consisting of CK1 delta/CK1 epsilon/beta-catenin/Tip60 is present in colon cancer cells, and this complex plays an important role in beta-catenin acetylation.

Summary: In this study, the Pockels electro-optic properties of ZrO2 and HfO2 orthorhombic Pbc21 and rhombohedral R3m ferroelectric phases are compared to those of the well-known rhombohedral R3c LiNbO3 Pockels material using density functional theory calculations. Three essential processes, including the electronic, ionic, and piezoelectric contributions, are explicitly investigated. The calculations reveal that the ionic part from the low-frequency phonon modes contributes the most to the electro-optic coefficients of LiNbO3, ZrO2, and HfO2, while the low-frequency phonon modes of ZrO2 and HfO2 rhombohedral R3m phase exhibit zero contribution to the Pockels coefficients.

Summary: WO3-TeO2 binary thin films were deposited by spray pyrolysis and characterized to study their electrochromic and coloration properties. Increasing TeO2 content after annealing led to the formation of the H2Te2O6 phase, improving electron-hole exchange and the coloration/bleaching process. The results show variations in hysteresis curve area and diffusion coefficient in response to the changes in TeO2 content.

Summary: Anti-Stokes photoluminescence (ASPL) is an efficient process of radiative recombination in nanocrystals of metalorganic and inorganic semiconductors with perovskite crystal structure, allowing for solid-state cooling or optical refrigeration. This review analyzes the mechanisms and efficiency of ASPL, considering factors such as size distribution, surface passivation, optical excitation energy, and temperature.

Summary: The article introduces the new concept of I-alpha beta-statistical convergence, a more generalized version of I-statistical convergence, and compares it with important results from Balcerzak et al. It also proposes two new notions related to rough weighted I-alpha beta-statistical convergence and investigates topological properties of these notions.
