The global incidence and prevalence of inflammatory bowel disease (IBD) has increased over the last 2-4 decades, likely because of the adoption of a more "western" lifestyle as well as improved detection and awareness, and Taiwan is no exception. To characterize the increasing burden of IBD, we conducted a comprehensive review of IBD in the existing literature. The following parameters were reviewed: background knowledge and current standard care for IBD, including natural history, epidemiology, pathogenesis, diagnosis, monitoring, and treatment. In addition, new imaging modalities and treatment options such as combined positron emission tomography and magnetic resonance enterography, new biologic agents, small-molecule therapy, biosimilar therapeutics, mesenchymal stem cell transplantation, and fecal microbiota transplantation, all of which have been introduced for IBD management, were reviewed. We also used the hospital-based as well as population-based Taiwan National Health Insurance Research Database to assess Taiwan-specific trends for comparison with global trends.

Red phosphors (e.g., SrLiAl3N4:Eu(2+)) with high thermal stability and narrow-band properties are urgently explored to meet the next-generation high-power white light-emitting diodes (LEDs). However, to date, synthesis of such phosphors remains an arduous task. Herein, we report, for the first time, a facile method to synthesize SrLiAl3N4:Eu(2+) through Sr3N2, Li3N, Al, and EuN under atmospheric pressure. The as-synthesized narrow-band red-emitting phosphor exhibits excellent thermal stability, including small chromaticity shift and low thermal quenching. Intriguingly, the title phosphor shows an anomalous increase in theoretical lumen equivalent with the increase of temperature as a result of blue shift and band broadening of the emission band, which is crucial for high-power white LEDs. Utilizing the title phosphor, commercial YAG:Ce(3+), and InGaN-based blue LED chip, a proof-of-concept warm white LEDs with a color rendering index (CRI) of 91.1 and R9 = 68 is achieved. Therefore, our results highlight that this method, which is based on atmospheric pressure synthesis, may open a new means to explore narrow-band-emitting nitride phosphor. In addition, the underlying requirements to design Eu(2+)-doped narrow-band-emitting phosphors were also summarized.

Recently, there has been considerable interest in investigating quantum entanglement in two-electron systems, such as two-electron model atoms and quantum dots. In this work, the quantum entanglement of the helium atom and helium-like ions are explored using the two-electron wave functions constructed by the B-spline basis. As a measure of the spatial entanglement, the linear entropy of the reduced density matrix is investigated for the ground state and the singlet excited 1sns 1 S states, with n = 2-10, of the helium atom. The variation of the spatial entanglement with the nuclear charges Z = 2-15 for the helium-like ions is reported. Results are compared with the existing predictions.

The quantum entanglement for the two electrons in three-body atomic systems such as the helium atom, the hydrogen negative ion and the positronium negative ion are investigated by employing highly correlated Hylleraas functions to represent the ground states of such systems. As a measure of the spatial entanglement, the linear entropy of the reduced density matrix is calculated for the ground states. The required four-electron (12-dimensional) integrals are solved analytically such that they are suitable for machine computations. Results are compared with other calculations when available.
