Summary: The semimicroscopic particle-hole dispersive optical model is used to describe the main properties of isoscalar giant multipole resonances in medium-heavy closed-shell nuclei, focusing on strength distribution, transition density, and probabilities of direct one-nucleon decay. The model is applied to analyze the characteristics of these resonances in the Pb-208 nucleus, and the calculation results are compared with experimental data.

Summary: We propose a framework that utilizes a continuous frequency space to describe and design solid-state nuclear magnetic resonance (NMR) experiments. This approach allows reverse engineering of experiments and is based on perturbation theory in a continuous Fourier space, resulting in time-independent effective Hamiltonians. The pulse scheme can be back-calculated from the desired effective Hamiltonian as a function of spin-system parameters. An example is provided to demonstrate how to back-calculate the rf irradiation in the MIRROR experiment from the desired chemical-shift offset behavior of the sequence.

Summary: The nuclear incompressibility is a key parameter of the nuclear equation of state, which can be extracted through measurements of the breathing mode of finite nuclei. The discrepancy between values extracted from Pb and Sn has raised the longstanding question of why tin is so soft. To solve this puzzle, a self-consistent quasiparticle random-phase approximation plus quasiparticle-vibration coupling approach has been developed. It is shown that the many-body correlations introduced by quasiparticle-vibration coupling play a crucial role in providing a unified description of the isoscalar giant monopole resonance in Sn and Pb isotopes. The best description of the experimental strength functions is given by SV-K226 and KDE0.

Summary: A salient feature of quantum mechanics is the inherent property of collective quantum motion, leading to enhanced transition probabilities. An appropriate definition of uncorrelated average motion, often expressed by single particle units, is crucial for assessing the extent of a collective quantity.

Summary: This study investigates the effects of conformal deformation of physical parameters on the measurement, Berry phase, and resonance of a spin. The evolution path of the Berry phase can be tunable by the conformal index, and the resonance frequency follows a quantization rule based on the Rabi frequency without deformation.

Summary: The purpose of this work is to investigate the continuum mechanical properties of a system of strongly interacting fermions using the framework of Fermi liquids. The Landau equation for the Fermi distribution function is transformed into a set of coupled fluid-dynamical equations for describing multipole distortions of the Fermi surface, up to l = 3. The set of fluid-dynamical equations is then applied to study wave disturbances in infinite nuclear matter and electric isoscalar giant resonances in spherical nuclei.

Summary: This study investigated the control of nonfat yogurt microstructure, textural properties, and syneresis through milk protein composition and smoothing temperature. The results showed that microgels play a crucial role in yogurt texture and are influenced by whey protein content and smoothing temperature. Optimizing these parameters may help improve nonfat stirred dairy gel.

Summary: Nuclear spin relaxation dispersion parameters can serve as indicators of the binding mode of a ligand to a protein. Hyperpolarization techniques, such as dissolution dynamic nuclear polarization, can provide signal enhancement without the need for isotope enrichment, offering an alternative method for determining ligand binding modes.

Summary: This paper addresses the issue of alpha particle confinement in fusion reactor design, focusing on the impact of neoclassical tearing modes and toroidal field ripple on particle loss, as well as the assessment of particle redistribution under an NTM with a reduced model. Results show that the synergistic effect of NTM and ripple is negligible, and particle loss fraction remains unchanged with increasing NTM amplitude. Only passing particles are affected by mode particle resonance, leading to profile flattening without increased loss.

Summary: Radioactive materials ionize air and produce molecules like ozone, which can be used as a marker for nuclear materials. This study focuses on ozone yield, saturation, and decay time as indicators for detecting actinides. It found that ozone levels in still air can serve as a secondary marker for special nuclear materials.

Summary: By using a nanoscale luminescent europium-organic framework (EuMOF), Ac-225 can be efficiently labeled in its crystal structure with sufficient retention stability. The close proximity between Ac-225 and Eu3+ allows for efficient energy transduction, generating enough photons for clear imaging. This study demonstrates the feasibility of directly monitoring Ac-225 in vivo using optical imaging, and EuMOF also shows notable effectiveness in tumor treatment.

Summary: Experiments at DA Phi NE-Frascati and J-PARC aim to produce K-D atoms and observe their X-ray cascade down to the 1S ground state, measuring the strong-interaction width and shift away from a purely Coulomb state. Predictions show a strong interaction upward level shift and width for the K-D atom 1S ground state, aligning with three-body K-D atom calculations and compared with pi D- atom phenomenology.

Summary: Lattice quantum chromodynamics calculations provide a new approach for ab initio predictions in nuclear physics, by extrapolating finite-volume results to free-space physical quantities. We investigated the effect of periodic boundary conditions on the binding energy of light nuclei using the stochastic variational method, and examined the limitations of the Luscher formula for different nuclear systems.

Summary: The study analyzes the large charge symmetry breaking (CSB) in the mirror hypernuclei and deduces an in-medium admixture amplitude A(I=1) asymptotic to 1.5% in the dominantly isospin I = 0 lambda hyperon. The research confirms previous findings regarding the lambda-sigma(0) induced in-medium admixture amplitude and explores the impact of SU(3) flavor symmetry on the lambda-nucleon interaction, highlighting the expected influences on the S = 1 and S = 0 spin channels.

Summary: The consequences of increasing the binding energy of the hypertriton ground state on s-shell hypernuclei are studied within a pionless effective field theory approach, finding that the Lambda nn(1/2(+)) resonance becomes broader and the spin-flip virtual state moves closer to the Lambda d threshold. The impact on femtoscopic studies of Lambda-deuteron correlations and the potential shallow bound state are discussed in relation with experimental observances.

Summary: The study shows that the extraction of the relative abundances of short-range correlated nucleon pairs using the generalized contact formalism (GCF) is sensitive to model parameters, with the light-cone GCF formulation significantly reducing this sensitivity and improving consistency with ab initio calculations. The ratio of similar mass isotopes is found to be sensitive to nuclear asymmetry dependence of SRCs and low-energy nuclear structure, suggesting the need for cross-section calculations that properly account for both nuclear structure and relativistic effects to improve accuracy.

Summary: The nature of Lambda nn and H-3(Lambda)*(J(pi) = 3/2(+), I = 0) states was investigated using a pionless effective field theory at leading order. The Lambda nn and (Lambda)(3)H* states were found to be unbound, with the (Lambda)(3)H* state being a virtual state. It was also suggested that the Lambda nn pole could potentially convert to a true resonance with Re(E) > 0. The stability of resonance solutions and accuracy of calculations were discussed and assessed.
