Summary: The nuclear structure of Se-66, a proton-rich nucleus beyond the N= Zline, was investigated using a neutron knock-out reaction. The analysis of the gamma-ray singles spectrum revealed two previously detected and three new transitions. Based on experimental data and theoretical calculations, it was proposed that 66Se exhibits shape coexistence.

Summary: A microscopic explanation of shape coexistence in the N=90, Z=64 region is proposed based on calculations of single particle energies. It is suggested that the coexistence is caused by the protons, which trigger stronger proton-neutron interaction and result in the shape/phase transition from spherical to deformed nuclei.

Summary: Human impacts on the natural world are increasing and are generally considered a threat to wildlife conservation and the persistence of species. However, not all human activities are antithetical to conservation and not all taxa are impacted in the same ways. A study on critically endangered Verreaux's sifakas in Madagascar found that certain human-related activities were perceived as threats by the sifakas, leading to immediate behavioral shifts. However, these activities did not have a discernible negative impact on the sifakas' population at the reserve.

Summary: The experimental results demonstrate that multiple coherent microcombs can coexist in monochromatically pumped Si3N4 microresonators, including TE-polarized soliton microcombs, TM-polarized Turing rolls microcombs, and cross-phase-modulation-induced TM-polarized microcombs. By heterodyning the comb lines, a specific frequency signal is extracted from the microresonator, and its coherence characteristics are analyzed.

Summary: Our study found that plants in nutrient-limited forests exhibit higher nitrogen resorption efficiency, while those in phosphorus-limited forests show higher phosphorus resorption proficiency, indicating a preferential resorption of the more limiting nutrient in response to nutrient limitation. Stoichiometric control was demonstrated by the positive relationship between NRE: PRE and leaf N:P ratios within each forest. Additionally, nutrient concentration controls were observed, with higher resorption proficiency in the nutrient-poor forest than in the nutrient-rich forest.

Summary: By utilizing strain engineering and chemical doping, the coexistence of multiple morphotropic phase boundaries (multi-MPBs) in highly strained La-doped BiFeO3 thin films has been demonstrated. The reversible switching of these multi-MPBs can be achieved by applying an electric field, leading to enhanced electromechanical coupling response compared to pure BiFeO3. This discovery opens up a new field for obtaining high-performance piezoelectric materials.

Summary: Reversible shape memory polymers with a broad melting temperature range were developed to overcome the limitation of existing polymers. The polymers were able to memorize multiple temporary shapes through a thermal programming process. By selectively activating partial melting and recrystallization at different temperatures, the polymers demonstrated reversible triple, quadruple, and quintuple shape memory effects. This research may have significant implications for the application of reversible shape memory polymers.

Summary: Parameter-free theoretical predictions and covariant density functional theory calculations indicate that shape coexistence in atomic nuclei can only occur on islands within specific regions of the nuclear chart. The existence of these islands is supported by data for even-even nuclei possessing certain bands, where the energy levels of specific states are close to each other. This study also briefly discusses a theoretical mechanism for multiple-shape coexistence.

Summary: A theoretical framework is proposed to quantify the thermodynamic properties of multicomponent hard colloidal mixtures. The phase behavior of mixtures of rods with spheres and rods with plates are predicted using this framework, taking into account the liquid crystal phases of both components. The study demonstrates a rich and complex range of phase behaviors, featuring a large variety of different multiphase coexistence regions. The approach can qualitatively account for certain multiphase equilibria observed in rod/plate mixtures and will be useful in tuning the phase behavior of shape-disperse mixtures in general.

Summary: Several current searches for physics beyond the standard model are focused on electron-capture decay of radionuclides implanted in cryogenic high-resolution sensors. Understanding the effects of the host material on the electron energy levels is necessary for accurate measurements. Using density-functional theory, the electronic structure of lithium in different atomic environments of a polycrystalline tantalum absorber film was modeled. The results show variation in binding energies and broadening of energy levels due to lattice sites, grain boundaries, and impurities, contributing to sensor peak broadening but not fully explaining it.

Summary: The development of quantum optomechanics has allowed for control and measurement of mechanical sensors in the quantum regime. By measuring the recoil of sensors containing isotopes that undergo nuclear decay, it is possible to reconstruct the total momentum of all emitted particles, including neutrinos. A nanometer-scale optically levitated sensor operated near the standard quantum limit can search for heavy sterile neutrinos and potentially measure the mass of light neutrino states.

Summary: The abundances of heavy elements after iron are influenced by a process called rapid neutron capture or r-process. This process is influenced by the competition between neutron capture, photo-disintegration, and beta-decay rates, and is ultimately dependent on the binding energy of neutron-rich nuclei. Researchers have found that the symmetry energy, which describes the binding energy of ground states, is unexpectedly enhanced at higher temperatures. This enhancement may suggest a similar enhancement at lower temperatures where neutron capture occurs.

Summary: More than 200 states up to 4.1 MeV excitation have been observed in 168Er with the 170Er(p, t) reaction at 25 MeV incident energy. A multistep coupled-channels analysis has been conducted for all the states to determine their spin and parity values, leading to the assignment of more than 100 newly determined values. The results show good agreement with previously reported values in the ENSDF database, making 168Er a well-known nucleus for low and medium spin states.

Summary: Ultralow Q-value 0 decays refer to decays with energies less than approximately 1 keV. These decays occur when the parent nucleus decays to an excited state in the daughter nucleus with an energy close to the Q value. They are of interest for neutrino mass determination experiments and atomic interference effects in nuclear decay. This paper provides an updated evaluation of atomic mass and nuclear energy-level data to identify potential ultralow Q-value 0 decay candidates. Precise atomic mass measurements using Penning trap mass spectrometry are needed for further study.
