Summary: Researchers developed a high-throughput platform to optimize genetically encoded voltage indicators for two-photon microscopy. They identified a new indicator, JEDI-2P, which is faster, brighter, more sensitive, and more photostable than previous indicators. JEDI-2P can be used to monitor voltage dynamics in various applications.

Summary: Three non-centrosymmetric alkaline earth vanadyl(IV) phosphate hydrates (M(VO)(2)(PO4)(2)·4H(2)O, M = Ca, Sr, Ba) were successfully synthesized using a mild hydrothermal technique. The large birefringence of these compounds, calculated from first principles, is mainly attributed to the parallel arrangement of the (2)[V2P2O14](infinity) layers and the force of hydrogen bonds. Furthermore, the optical and thermal properties of these compounds were studied, providing insights for exploring nonlinear optical materials with large birefringence in vanadyl phosphate hydrates.

Summary: The study introduces a high-capacity multi-dimensional shingled optical recording technique in silica glass using femtosecond lasers. Through a 3D shingled configuration, the size of data voxel is reduced to 500 nm x 500 nm x 1.0 mu m, surpassing the diffraction limit. The insights from this work may inspire applications in optical data storage, sensor, microfluidic, micro-mechanics, geometric phase elements, photonic crystal, and quantum mechanics.

Summary: We have developed a system for off-axis optical scanning holography (OSH) and successfully recorded holograms without using heterodyning or a spatial light modulator for temporal frequency shifting. A phase monitoring module is included to mitigate phase fluctuation. Reconstruction without the zeroth-order light and the twin image is achieved through single sideband filtering and phase compensation. The coherent-mode and incoherent-mode properties and practical issues of off-axis OSH are also discussed.

Summary: Transparent microelectrodes have been widely studied in the biomedical field due to their advantages in simultaneous electrical and optical interrogation of cell/tissue activity. In this study, a microelectrode array (MEA) with gold-coated silver nanowires (Au-Ag NWs) was designed to achieve desirable mechanical stretchability, optical transparency, electrochemical performance, and chemical stability. The MEAs exhibited high optical transparency, low electrochemical impedance, stable chemical and electromechanical performance, and superior capability for colocalized electrophysiological and optical mapping of cardiac function.

Summary: AMn(2)P(2) (A = Ca, Sr) materials were studied for the first time using ab-initio-based on Density Functional Theory (DFT). The study revealed their stable structure, thermal, electrical, mechanical, elastic anisotropic, and optical characteristics. The results showed consistency with experimental data, confirming their thermodynamic and dynamical stability, as well as their metallic nature. The materials also exhibited potential applications in optoelectronics and photovoltaics, with CaMn2P2 identified as a better Thermal Barrier Coating (TBC) material than SrMn2P2 due to its lower thermal conductivity.

Summary: We report an all-solid-state narrowband lidar system for simultaneous detection of Ca and Ca+ layers over Yanqing. The system's transmitter, based on OPO and OPA techniques, generates coherent light for detection of thermospheric and ionospheric Ca+ and Ca layers with higher power and stability compared to conventional dye-based systems. The lidar system demonstrated high sensitivity and reached a height of approximately 300 km.

Summary: A series of divalent metal orthophosphate compounds were synthesized and their densification behavior, optical properties, and dielectric properties were investigated. The orthophosphate ceramics exhibited low dielectric constants and high-quality factor values, and the differences in their dielectric properties could be explained by chemical bonding.

Summary: In this study, a samarium-doped perovskite oxide photochromic material with good fatigue resistance was reported, achieving the highest contrast value of 90.05% for downshifting emission-based photochromic materials. The mechanisms of photoluminescence, photochromism, and optical switching were discussed in detail, and the good reproducibility of the optical switching was demonstrated.

Summary: The addition of charge compensators significantly improved the excitation and emission properties of the Ca-2.65(PO4)(2):0.35Tb(3+) phosphor, with Li+ ions particularly enhancing emission intensity and color purity. Optimizing the concentration of Li+ charge compensator led to a 260% increase in green emission intensity compared to the unmodified phosphor. These findings suggest potential applications in the design of phosphors for light-emitting diodes.

Summary: K+ channels play crucial roles in lung physiology. The Ca2+-activated K+ channels (K-Ca) have recently gained more attention and efforts are being made to develop selective medications targeting these channels. Among the K-Ca channel family, the K(Ca)2 channel subtypes and the K(Ca)3.1 channel are voltage-independent K+ channels that mediate membrane hyperpolarization induced by Ca2+. This article discusses the different subtypes of K(Ca)2 and K(Ca)3.1 channels and their functions in respiratory diseases, as well as the pharmacology of these channels and their link to respiratory ciliary regulations.

Summary: Studies have shown that (Ba,Ca)(2)(CO3)(2) can incorporate significant amounts (up to 6 mol%) of europium on lattice sites. This solid solution is potentially useful for the solidification of nuclear waste streams and has a larger one-phase-field than previously thought. The compounds synthesized here have similar molar volumes to naturally occurring (Ba,Ca)-double carbonates.

Summary: This study proposes a multi-penalized state-space model for analyzing unobserved dynamics, using a data-driven regularization method. Novel algorithms are developed to solve the model, and a cross-validation method is introduced to evaluate regularization parameters. The effectiveness of this method is validated through simulations and real data analysis, enabling a more accurate exploration of cognitive brain functions.
