Summary: This review explores quantum field theories and conformal field theories with global symmetries in the large charge limit, revealing that at low energies, the sectors with large charge can be described using a hybrid form of Goldstone's theorem. The associated effective field theory in the infrared enables computation of anomalous dimensions and operator product expansion coefficients, offering a well-defined expansion in inverse powers of the global charge.

Summary: Neutron matter, which is closely related to neutron stars and systems such as cold atom gases, is an interesting and computationally accessible system in nuclear physics. The configuration-interaction Monte Carlo (CIMC) method is a stochastic many-body technique that allows us to study strongly coupled systems. Unlike other quantum Monte Carlo methods used in nuclear physics, the CIMC method can be formulated directly in momentum space, making it efficient for utilizing nonlocal interactions. In this study, we extend the CIMC method to include three-nucleon interactions using the normal-ordered two-body approximation. We present results for the equation of state of neutron matter that are consistent with other many-body calculations using low-resolution chiral interactions, and also provide predictions for the momentum distribution and the static structure factor.

Summary: This article presents an expression of partial-wave expansion for three-baryon interactions in chiral effective field theory, which is more general compared to previous methods. By utilizing this derived formula, the folding potential of a ?-deuteron is evaluated, providing valuable information for future studies on ?NN three-baryon forces and their contribution to hypertritons through sophisticated Faddeev calculations. The microscopic understanding of ?NN three-baryon forces, along with two-body ?N interactions, is crucial for the description of hypernuclei and neutron-star matter.

Summary: This study evaluated risk factors and outcomes of geriatric patients with uncertain head injury. It found that although the rate of intracranial hemorrhage (ICH) among patients with uncertain head trauma was eight times lower than those with definite head trauma, the risk of ICH is still high enough to warrant CT imaging of all geriatric patients with uncertain head injury.

Summary: Physical systems with shallow two-body bound or virtual states exhibit a transition from continuous scale invariance to discrete scale invariance. This symmetry leads to a universal behavior independent of the underlying interaction details, known as Efimov physics. By linking physical systems to their unitary limit, universal properties can be identified, with nuclear systems belonging to this class of universality.

Summary: The Efimov window is a specific energy region where few-body systems are loosely bound. Simple potential models characterized by few parameters can be used to describe the dynamical properties of these systems, and the potential strength can be varied to explore the window. The Gaussian potential has been commonly used to represent the universal window. The gaussian-level function is a potential-independent function that contains finite-range corrections and plays a vital role in comparing theoretical predictions with experimental data.

Summary: In this study, the authors investigate the processes d(d, p)3H and d(d, n)3He, which are relevant for energy production and big-bang nucleosynthesis. They use the ab initio hyperspherical harmonics method to accurately solve the four-body scattering problem. By varying the cutoff parameter, they estimate the theoretical uncertainty for various observables including the astrophysical S factor and quintet suppression factor.

Summary: We study bosonic systems with a shallow bound state or a large two-body scattering length. Using effective field theory, we construct a series of potential terms that decrease in importance for the binding energy. The leading-order potential terms consist of a two-body term, usually attractive, and a three-body term, usually repulsive, to prevent system collapse. We investigate the cutoff's role in the leading-order description and extend the exploration to the next-to-leading-order terms. We introduce three-body forces based on the stability requirement of the N-body system and parametrize the potential to describe the energy of 4He clusters accurately. Finally, we explore the possibility of describing the atom-dimer scattering length simultaneously.

Summary: The Hohenberg-Kohn theorem and the Kohn-Sham equations are reformulated in terms of a specific many-body density and potential, with energy being a functional of this density that, when minimized, leads to the ground-state energy of the system. An analogy of the Kohn-Sham equation is solved in the case of He-4 atomic clusters to demonstrate the advantages of this formulation in terms of physical insights.

Summary: This study presents further analysis of the three- and four-neutron systems in the low energy regime using adiabatic hyperspherical methods. The results show no evidence of a 4n resonance at low energy, while the long-range behavior exhibits an attractive universal characteristic in the low-energy regime.
