Summary: In the T-matrix form of the transfer reaction, global optical model potentials (OMPs) are widely used to compute the scattering wave function and transition operator. Different sets of global OMPs can equally reproduce the scattering cross section, and their effects on transfer cross sections vary with energy and target mass. Furthermore, the spin-orbit coupling term of global OMPs has a non-negligible influence on the transfer cross sections.

Summary: We propose a new nonlocal form of the nucleon-nucleus optical potential and demonstrate its reliability. We extend the nonlocal potential to include the excitation of the nuclear core and develop an energy-independent proton-10Be potential that reproduces the experimental data at low energies. Using rigorous three-body Faddeev-type equations, we apply the new potential to the study of deuteron stripping and pickup reactions 10Be(d, p)11Be and 11Be(p, d)10Be in the momentum-space partial-wave framework. The achieved description of the experimental data is considerably more successful compared to previous studies with local potentials, possibly indicating an increased predicting power of the proposed calculational scheme.

Summary: Transfer reactions are important for determining spectroscopic factors and astrophysical reaction rates. However, their theoretical evaluation is typically limited by the absence of structure degrees of freedom in standard reaction theory. The recently developed coupled-channel Gamow shell model (GSM-CC) is proposed as a method to include internucleon correlations in transfer cross sections for medium nuclei. The 40Ca(d, p) transfer reaction is studied as an example using the GSM-CC, successfully reproducing experimental data with a phenomenological Hamiltonian.

Summary: We analyzed the 16C +p and 16C +d reactions and described the 16C nucleus using the four- and five-body continuum discretized coupled channel method. Our analysis of transition amplitude and inclusion of pseudo-states showed good agreement with experimental results, allowing for the study of proton and deuteron elastic scattering.

Summary: The study retrospectively collected clinical data of 24 cases of vitamin D-dependent rickets type 1A, and found that partial loss-of-function variation may be associated with a milder disease phenotype. Patients had good clinical, biochemical, and radiological outcomes after treatment, but adherence is crucial to prevent complications.

Summary: The classic criteria to determine if a second-order irreversible gas-liquid reaction proceeds in the instantaneous regime are based on the Hatta number and the infinite enhancement factor. However, there is no consensus on the latter threshold value, which depends on reactant concentrations and rate coefficients. This work presents an extended expression and a new dimensionless number to improve the criteria and demonstrates the importance of considering the position of the reaction plane.

Summary: In this study, a numerical quantification of a perturbative correction to the adiabatic distorted wave approximation theory was provided and compared with continuum-discretized coupled channel predictions. The perturbative correction involves an additional, nonlocal term in the effective deuteron-target ADWA potential in the entrance channel.

Summary: In this study, four porous organic polymers (POPs) were designed and synthesized for photocatalytic aerobic oxidation reactions. It was found that the introduction of thiophene into one of the POPs resulted in the highest photocatalytic activity. Theoretical calculations confirmed that thiophene increased conjugation and promoted electron polarization, facilitating charge separation and ROS generation.

Summary: In this study, fluorescent small molecules with full-color luminescence were constructed by introducing benzene, thiophene, and C-C double-bond units to modulate the p-bridge length. These compounds covered the entire visible spectrum and exhibited high luminescence efficiency. LEDs fabricated using some of these compounds displayed better performance than commercial WLEDs, including higher luminous efficiency and color rendering index.

Summary: A highly active and stable CuP2/NiCuP/g-C3N4 electrocatalyst is constructed via phosphorization for HER and OER. The heteronanojunction between CuP2 and NiCuP, as well as the abundant active sites and conductive g-C3N4 support, contribute to the excellent performance and stability of the electrocatalyst. This study provides valuable insights for designing cost-effective bimetallic alloy-phosphide HER/OER electrocatalysts for sustainable energy-conversion applications.

Summary: In this study, a new parameterization of DFTB3 was developed to overcome the challenges in describing the phosphate group and its reactions with nitrogen species using semi-empirical quantum chemical methods. The improved DFTB3 method accurately represents biochemical phosphorylation and hydrolysis reactions involving P-N bonds through extended-sampling QM/MM simulations. The parameter set was validated using reaction models and applied to study the complex mechanisms of anticancer drug hydrolysis and histidine kinase protein autophosphorylation.

Summary: The study focuses on the fermion-fermion-dimer recombination process in spin 1/2 fermion systems, finding that the recombination rate is linearly related to the effective range parameter near the unitary limit, enabling simple parameterization for any potential model. These results are useful for evaluating different methods in three-cluster breakup and recombination calculations in four-particle systems.

Summary: This study focuses on the effects of Delta isobar excitation in the electrodisintegration of 3He, treating it on the same level as nucleons. Beyond the quasi-elastic peak, the transverse response functions R-T and R-T' are visibly affected. This leads to significant Delta isobar effects on inclusive and exclusive electron polarization asymmetries in specific kinematic regions. Measurement in the proposed regime can provide insight into models of nuclear forces and currents.

Summary: This study proposes an approach to solve the problem of describing weakly bound few-body systems with strong short-range repulsion. It is applied to a realistic system of four 4He atoms. The results show linear correlations between three- and four-body quantities, and the extrapolation method improves the accuracy of the calculations. The binding energies and scattering results agree with previous studies.

Summary: In this study, the potential use of a pure van der Waals potential as a starting point for an effective field theory to describe three-body processes in ultracold atomic systems is evaluated using a system of three He-4 atoms. The results demonstrate that the approach is effective and shows good agreement with realistic potential results. Additionally, it is shown that no three-body force is required at leading order in this effective field theory approach, and a universal correlation between three-body observables exists in the absence of an Efimov three-body parameter under universal van der Walls physics.

Summary: The study investigates the Efimov tetramers in the region with negative two-boson scattering length by solving rigorous four-particle scattering equations. The tetramers exhibit finite width in the entire regime, broadening rapidly in the resonance regime but remaining narrower than the associated trimers. Resonant behavior is most clearly seen in the four-particle recombination rate.

The data are in general agreement with various theoretical predictions based on Siegert theorem or explicit inclusion of meson-exchange currents.
