Summary: In this study, we perform a perturbative check of the BC-type sum rules in the quark target model and the Yukawa model, and find that the BC-type sum rules hold for dimensional regularization (DR) but are generally violated when using a cutoff.

Summary: In this study, the photothermally induced nanoscale dynamics of rapid melting and resolidification of a thin layer of molecular material surrounding a nanoparticle were investigated using an all-optical approach. By modulating the medium's dielectric constant through absorption of a low-duty-cycle laser pulse train by a single nanoparticle, the experimental data were compared with results from coupled optical-thermal numerical simulations to infer a phase change and the liquid/solid interface dynamics. The experimental/computational workflow presented in this proof-of-principle study will facilitate future explorations of material parameters at nanoscale.

Summary: In this letter, the results for the isovector polarized quark quasi-distribution functions in the large-Nc limit are reported, which were calculated using the chiral quark-soliton model. It is found that the polarized quark quasi-distributions show good convergence to the light-cone PDFs in the limit of high nucleon boost momentum or velocity.

Summary: In this paper, a deep learning approach for automated segmentation of apple defects is proposed. The method outperforms general-purpose deep learning architectures commonly used for segmentation tasks in terms of segmentation accuracy. Additionally, the proposed method has low computational cost and can be used for visual-based apple inspection.

Summary: We propose an anisotropic programmable coding metasurface composed of digital coding elements integrated with PIN diode. The diode's states can be controlled in real time by external voltages, and the metasurface unit is controlled by the FPGA. The metasurface can switch polarization states in two orthogonal directions separately and achieve remote scattering control at any angle with convolution coding.

Summary: We analyze the generalized quasi, Ioffe-time, and pseudodistributions of the valence quarks in the pion at the quark model scale. We use the framework of the Nambu-Jona-Lasinio model and investigate the basic question of how fast the pion has to move to effectively reach the infinite momentum limit, where the approach can provide the information on the generalized parton distribution functions. With developed analytic expressions, we conclude that to effectively approach the infinite momentum limit in the Ioffe-time distributions for values of the Ioffe-time accessible in lattice QCD, one roughly needs the pion momenta of the order of similar to 3 GeV.

Summary: This study presents quasi-real-time dual-comb spectroscopy using two Yb:fiber combs with approximately 750 MHz repetition rates. A computational coherent averaging technique is employed to correct timing and phase fluctuations of the measured dual-comb interferogram. Quasi-real-time phase correction is performed every 1.5 seconds, assisted by coarse radio frequency phase-locking. After resampling and global offset phase correction, the RF comb linewidth is reduced and the line-to-floor ratio increases. Simultaneous offset frequency correction is used to correct the aliased RF spectrum, achieving optical coverage of approximately 180 GHz.

Summary: Meat adulteration is a significant issue in the meat supply chain, and it can seriously harm consumers' economic and health interests. To address the problem of mutton adulteration and reduce testing costs, a triplex real-time PCR method with melting curve analysis was developed to identify three meat categories simultaneously.

Summary: We studied the factorization relations between quasi gluon GPDs and twist-2 GPDs. Perturbative coefficient functions were obtained at one-loop level, free from any collinear or I.R. divergences. Ghost contributions were added for the factorization of quasi gluon GPDs to obtain gauge-invariant results. Our work showed that the mixing pattern of nonlocal operators in quasi gluon GPDs is the same as that of local operators, involving gauge-invariant operators, BRST-variation operators, and operators with EOM operator. The factorization relations were obtained for all quasi gluon GPDs, and the relations between quasi gluon PDFs and twist-2 PDFs were also derived by taking the forward limit.

Summary: Variable renewable energy sources are increasing their share in the world energy mix, but their uncertainty poses challenges to the safe operation of electric grids. Quasi-real-time, peer-to-peer electricity markets utilizing blockchain technology are a promising solution at the distribution grid level, but there are still technical challenges to overcome.

Summary: We propose a drift-free visual compass that estimates the rotational motion of a camera by recognizing structural regularities in a Manhattan world. Our approach hybridizes data sampling and parameter search strategies to achieve quasi-global optimality and high efficiency. Experimental results on real-world datasets demonstrate that our method outperforms other state-of-the-art approaches in terms of accuracy, efficiency, and stability.

Summary: In this letter, the authors expand upon the previous work to demonstrate the entanglement observed in top quark interactions. They propose that the thermal component caused by proton collisions with top quarks emerges from entanglement within the proton wave function, and they use published results to show the expected behavior.

Summary: In this study, we investigate the near-threshold meson photoproduction from protons and nuclei and explore the possibility of observing non-strange hidden-bottom pentaquark states through differential observables. We calculate the excitation functions and energy/momentum distributions for different production processes and propose that future experiments at high-luminosity electron-ion colliders could provide evidence for the existence of these hidden-bottom pentaquark resonances.

Summary: This study presents a microscopic investigation of the electromagnetic properties of the low-lying states of single-A hypernucleus 9ABe using the HyperGCM method based on covariant density functional theory. The results are compared to those of a particle-rotor model (PRM) and show close agreement. It is found that the electric quadrupole transition strengths are more sensitive to the coupling strengths of the AN interaction than the magnetic moments and M 1 transition strengths.
