Summary: The study focuses on the implications of nonzero neutrino masses for degrees of freedom and interactions beyond the Standard Model, specifically comparing the nature of massive neutrinos as Dirac fermions versus Majorana fermions. It investigates the kinematics of heavy neutral lepton decays in detail and explores the differences in behavior between polarized Majorana-fermion and Dirac-fermion decays, shedding light on the nature of new fermions and their decay interactions.

Summary: This study systematically investigates fully-heavy tetraquark states using a nonrelativistic quark model based on lattice-QCD studies. Multiple narrow resonances are found in all studied tetraquark systems, including resonances reported by the LHCb Collaboration. Further experimental examinations are suggested for the predicted resonances.

Summary: The study reveals the formation of a Borromean droplet in three-component ultracold bosons, where only ternary bosons can form a self-bound droplet due to collective many-body effects. Outside the Borromean regime, there is competition between ternary and binary droplets, leading to droplet phase separation. The transition between different droplets and gas phase can be conveniently tuned by boson numbers and interaction strengths.

Summary: In this study, the impact of the observer's motion on the clustering signal in galaxy distribution and the Kaiser rocket effect is examined both analytically and numerically. While the Kaiser rocket effect can significantly bias cosmological parameter inference in idealistic full-sky surveys dominated by cosmic variance, it is not a major concern for forthcoming surveys with realistic masks and selection functions, except for possible implications on primordial non-Gaussianity studies. This systematic effect is well understood and should be accounted for using various approaches.

Summary: This article introduces a theoretical two-layer neural circuit for storing stimulus occurrence frequencies. Through the implementation of two models, these circuits can robustly track stimulus occurrence frequencies and expand the traditional novelty-familiarity memory axis from binary to discrete with multiple possible values.

Summary: This paper presents a novel single-bitline 9-transistor (SB9T) SRAM based on FinFET technology, suitable for low-power near-threshold operation. Compared to other seven contemporary SRAMs, the proposed design demonstrates better performance in terms of read stability, writability, and power consumption.

Summary: At a bifurcation point, a small change in parameter causes a qualitative change in the system. Quantum fluctuations wash out this abrupt transition, enabling emission of quantized energy below the classical bifurcation threshold. A generic method is proposed to derive a characteristic function of photon counting close to a bifurcation threshold, based on the universality of the Martin-Siggia-Rose action.

Summary: The study demonstrates that the contributions of the resonance rho(770) to the three-body decays of B mesons are relatively small. However, it is possible that about 20% of the total three-body branching fraction for a specific process could come from the subprocess p(770) -> K+ (K) over bar (0). Additionally, the estimated branching fractions for rho(770)(+/-) decay into the kaon pair and the neutral rho(770) decay into different kaon pairs will be tested by future experiments.

Summary: The FBI-CPA is a novel observable for measuring CP asymmetry in multi-body decays of heavy mesons. It can isolate the CP asymmetry associated with interference of different wave amplitudes and effectively double the statistics compared to conventional methods. It is suggested to perform measurements of FBI-CPA in three-body decay channels of charm and beauty mesons.

Summary: In this study, a near-threshold proton resonance in B-11 was observed using the inverse kinematics method and a beam of the radioactive isotope Be-10. The results indicate that this resonance state exhibits the characteristics of a threshold resonance, making it an ideal case for studying quantum near-threshold many-body dynamics of unstable states.

Summary: A general formulation was developed to characterize near field radiative heat transfer in three-grating systems, showing a remarkable increase in heat flux by introducing asymmetric modulators. The forward and reverse scenarios in asymmetric three-grating systems offer high flexibility in manipulating heat transfer rate. These findings may pave the way for enhancing and modulating heat transfer rate in various potential applications.

Summary: By combining heavy quark effective theory and chiral perturbation theory, this study predicts the spectrum of nonstrange and strange states in the beauty meson family. Utilizing full leading self-energy corrections and leading power corrections, the masses of beauty mesons are successfully predicted, with some yet-to-be-discovered states identified. These predictions may offer valuable insights for further experimental exploration.
