Summary: This paper demonstrates that the purely real weak value can also shift the frequency-domain pointer when using a broad-spectrum light source, due to the different postselection probability of different frequencies. The weak measurement with real weak value can be used for the estimation of time delay, and it is found to have the same high resolution as the standard weak measurement in some sensitive regions.

Summary: A novel hypothesis suggests that the right homolog of Broca's area may play an important role in patients with attention deficits and language and speech disorders, as observed in healthy male right-handed long-term meditators. Further research is needed to explore the role of the right Broca's area, especially during meditation.

Summary: This paper improves the precision of estimating an unknown parameter by introducing a precoupling process with properly chosen interaction operators. By tracking the meter wave functions, it is found that the improvement in estimation precision comes from a precoupling induced modulation of the meter wave function, reaching the most sensitive regime with respect to the parameter. The estimation error is effectively suppressed by averaging the estimations resulted from different initial meter states. These results are demonstrated through a numerical simulation compared to the standard weak-value amplification scheme.

Summary: The half-life of Dy-154, a pure alpha-emitter, was re-measured and found to be (1.40 +/- 0.08).10(6) years, reduced by a factor of similar to 10 compared to the currently adopted value. This precise value has implications for testing nucleosynthetic models, disposal of irradiated target materials, and re-evaluation of excitation functions for Dy-154 production.

Summary: We investigate the recoil corrections in superallowed beta decays of T 1/4 1, JP 1/4 0 thorn nuclei by independently determining the mean square charged weak radius model using multiple charge radius data across the nuclear isotriplet. Our findings suggest that the existing theory uncertainty in the statistical rate function f might have been substantially underestimated compared to model estimations. We discuss the implications of our proposed strategy for precision tests of the standard model, including the potential alleviation of the first-row CKM unitarity deficit, and advocate for new experiments in charge radius measurements.

Summary: We investigate the boosted displaced signatures in the Type-I seesaw mechanism associated with the B - L gauge symmetry. Two scenarios are considered: (a) three degenerate right-handed neutrinos with Yukawa couplings reconstructed from observed neutrino masses and mixing; (b) one right-handed neutrino decoupling from observed neutrino mass generation, allowing arbitrarily small coupling. A PYTHIA based simulation is performed to determine the parameter regions sensitive to CMS, ATLAS, proposed FCC-hh detector, and MATHUSLA, considering the B - L gauge boson mass, neutrino Yukawa couplings, and right-handed neutrino mass at center-of-mass energies of 14, 27, and 100 TeV. The boost effect enhances displaced decay lengths and hinders the probe of Majorana nature of neutrinos.

Summary: Rare event physics requires detailed background control, high-performance detectors, and custom analysis strategies. Cryogenic calorimeters are effective tools for next-generation experiments, with CUPID-0 being a promising example. By analyzing delayed coincidence, researchers were able to extract time differences between decays and evaluate the Po-216 half-life.

Summary: Significant discrepancies were observed when decay-correcting Sb-122 gamma-peak count rates to a reference time, leading to a new measurement of the Sb-122 half-life value. The resulting values were lower than the preexisting recommended value, highlighting the need for further research and verification in this area.

Summary: Several analytical models have been developed to describe the evolution of fatalities arising from the COVID-19 pandemic, including the simplified D model and the more accurate ESIR model with recovery. The models predict similar trends in the pandemic evolution, showing a rapid increase followed by a slow decline in death cases. These results suggest that COVID-19 is highly contagious, with a majority of people becoming asymptomatic and eventually recovering.

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: Coulomb excitation of 102Ru was performed using 12C and 16O ions, analyzing the populations of various states as a function of scattering angle. The results were compared with calculations, showing discrepancies in some states' populations compared to previous measurements. The weakly populated 2+3 state and its transition probability to the 0+2 state were also observed and calculated. The results were compared with theoretical calculations using the Gogny-D1S interaction.

Summary: The research focused on obtaining spectroscopic information on states in Ba-136, resulting in the observation of 102 excited states, with 52 being reported for the first time. A comparison of experimental data with theoretical predictions showed reasonably good agreement at lower energies, but divergence at higher energies, possibly due to the limitations in resolving a large number of nearly degenerate states.
