A series of experimental studies on TCM yin-yang theory performed by researchers of integrated western and Chinese medicine was aiming at the seeking of the real objective nature of yin-yang. However, no matter how you exclusively equalize any pairs of life phenomena or materials to yin and yang, you will mix up the relationship between generality and specificity, concrete and abstract, which would torture the real nature of things. The original intention of the researchers failed. However, during the process of experiments, they found the mechanism of medicines for strengthening yang and nourishing yin and its indications, and the obvious mutual restricting action of two agents for strengthening yang, Radix Aconiti lateralis preparata and Cortex Cinnamomi, which was unkown before, and this is even of more significant theoretical and clinical values. The proposal of "Adjustment of the Regular Threshold of yin and yang" will deepen the recognition on the mechanism of human regulation and this should gain positive appraisal.

In this work, a theoretical approach is developed to investigate the structural properties of ionic microgels induced by a circularly polarized (CP) electric field. Following a similar study on chain formation in the presence of linearly polarized fields [T. Colla , , 2018, , 4321-4337], we propose an effective potential between microgels which incorporates the field-induced interactions a static, time averaged polarizing charge at the particle surface.

The two-dimensional electron gas (2DEG) is a fundamental model, which is drawing increasing interest because of recent advances in experimental and theoretical studies of 2D materials. Current understanding of the ground state of the 2DEG relies on quantum Monte Carlo calculations, based on variational comparisons of different Ansätze for different phases. We use a single variational ansatz, a general backflow-type wave function using a message-passing neural quantum state architecture, for a unified description across the entire density range.

We experimentally study cosmological particle production in a two-dimensional Bose-Einstein condensate, whose density excitations map to an analog cosmology. The expansion of spacetime is realized with tunable interactions. The particle spectrum can be understood through an analogy to quantum mechanical scattering, in which the dynamics of the spacetime metric determine the shape of the scattering potential.

A combined experimental and theoretical study is carried out on the three-body recombination process in a gas of microwave-shielded polar molecules. For ground-state polar molecules dressed with a strong microwave field, field-linked bound states can appear in the intermolecular potential. We model three-body recombination into such bound states using classical trajectory calculations.

Cell layers are often categorized as contractile or extensile active, nematics but recent experiments on neural progenitor cells with induced +1 topological defects challenge this classification. In a bottom-up approach, we first study a relevant particle-level model and then analyze a continuum theory derived from it. We show that both model and theory account qualitatively for the main experimental result, i.
