Summary: In this study, the unique Bloch-Floquet and non-Bloch band structures of a photonic Floquet medium are experimentally revealed in the microwave regime, with a one-dimensional array of time -periodically driven resonators. These non-Hermitian band structures are shown to be two measurable distinct subsets of complex eigenfrequency surfaces of the photonic Floquet medium defined in complex momentum space.

Summary: This study presents an approach to autonomously identify and select the optimal target for segmenting infected regions of the lung from chest computed tomography images. It utilizes a semi-supervised dual-branch framework for training, using both expert-annotated and automatically segmented data. The approach gradually improves the accuracy of the final model by switching supervision targets and utilizing noisy labels in the early stages of training.

Summary: Applying the planetary boundary for the freshwater framework at the regional level is crucial for supporting local water management, but there is significant uncertainty involved. This study estimates regional freshwater boundaries with reduced uncertainty and explores the potential of different trade patterns in mitigating boundary exceedance. The findings indicate that the current trade pattern in China's provinces limits the effectiveness of trade in alleviating regional freshwater boundary exceedance, and relying solely on increased imports will not reverse the exceedance in most importing provinces.

Summary: Although real materials are finite in size, electronic structure theory is based on the assumption of infinitely large solids, which has led to a debate on the location of the vacuum level. A new analytic real-space potential-unfolding approach is introduced to uncover the vacuum level in infinitely large solids, revealing an unknown bulk quadrupole offset with respect to the vacuum level in the absence of a physical surface. This theory identifies intrinsic contributions of a bulk solid to its surface and interface properties, resolving ambiguities surrounding the band alignment between matters.

Summary: In this article, the energy landscapes and metastable behavior of Ising and Potts models on two-dimensional square or hexagonal lattices in the low-temperature regime are investigated. The study focuses on the absence of an external magnetic field in these models, revealing a large and complex saddle structure between ground states. By analyzing the saddle structures and temperature thresholds, the conditions for metastable states and Eyring-Kramers formula are rigorously established, providing insights into transitions between ground states and the energy landscape.

Summary: Polyploidization plays a critical role in species evolution, and effective identification of polyploid types is important for studying the evolutionary mechanism. However, current methods have limitations. To address this, researchers developed the PolyReco method, which can automatically label collinear regions and recognize polyploidy events. Validation experiments showed the effectiveness of this method, and it has the potential to be a reference for other polyploid classification methods.

Summary: Forests play a crucial role in mitigating climate change by sequestering carbon, but they can also impact the climate system by altering cloud cover. Research suggests that afforestation generally increases low cloud cover, leading to cooling effects on the planet, with the extent of this effect varying based on forest type, such as needleleaf forests in Europe generating more clouds.

Summary: In this study, we computed the photon-quark and Higgs-gluon form factors to four-loop order within massless perturbative quantum chromodynamics. Our results provide ready-to-use building blocks for (NLO)-L-4 cross sections for Drell-Yan processes and gluon-fusion Higgs boson production at the LHC, and we present complete analytic expressions for both form factors and show several of the most complicated master integrals.

Summary: We study the Sudakov form factor in the off-shell kinematic regime of planar N=4 supersymmetric Yang-Mills theory, which is achieved by considering the theory on its Coulomb branch. We show that both the infrared-divergent and finite terms exponentiate up to three loops, with the coefficient determined by the octagon anomalous dimension. This behavior contradicts previous conjectural accounts. We also find that the logarithm of the Sudakov form factor is equivalent to twice the logarithm of the null octagon O0, which has a closed form expression for all values of the 't Hooft coupling constant and kinematical parameters.

Summary: We calculate the four-loop corrections to the Higgs-bottom vertex in massless QCD and provide analytic results for all color structures. The infrared poles of the renormalized form factor match the predicted four-loop pattern. Additionally, we utilize the results of the form factors for Higgs-bottom, photon-quark, and Higgs-gluon to determine hard matching coefficients in soft-collinear effective theory up to four-loop accuracy.

Summary: This study analytically computed all four-loop QCD corrections to the photon-quark and Higgs-gluon form factors involving a closed massless fermion loop. It also confirmed a previous conjecture for the analytical form of the nonfermionic contributions to the collinear anomalous dimensions of quarks and gluons through the calculation of nonplanar vertex integrals.
