Summary: In one-dimensional quantum gases, there is a duality between hard core bosons and noninteracting fermions. However, the exact duality connecting strongly interacting bosons to weakly interacting fermions is still unknown at the field theory level. This study proposes a solution to this problem by regularizing the pointlike interaction between fermions in one dimension, which induces a discontinuity in the wave function proportional to its derivative. By introducing a weak potential for small interaction strengths, standard methods of diagrammatic perturbation theory can be applied to strongly interacting bosons.

Summary: The addition of PMMA to PLLA/PHB blends transforms the morphology of the blends by forming an interfacial nanolayer, leading to significantly increased elongation and toughness while maintaining high stiffness and strength. This generic strategy can be applied to design other mechanically robust biocomposites for advanced green devices.

Summary: A new ultrafast laser-induced SMSI strategy has been proposed for constructing SMSI on a CeO2-supported Pt system, leading to enhanced activity and stability of the catalyst through the formation of surface defects and thin overlayer. This strategy can be extended to other noble metal systems and non-reducible oxide supports, providing a universal approach for engineering high-performance supported noble metal catalysts.

Summary: In this study, the formation of hybridized modes between a gold nanodisc and a nanorod is explored numerically and experimentally. The plasmon properties of connected and disconnected systems are compared. The results show a good agreement between experimental measurements and numerical predictions. The methods and analyses presented in this work can be applied to various applications in light-matter interactions, biosensing or strain monitoring.

Summary: This article presents a regularization method for preserving the strong-weak duality of pointlike interactions, contrary to previous known regularizations. This allows perturbative use of the duality, which is illustrated in the Lieb-Liniger model at strong coupling.

Summary: The study focuses on a structural-acoustic wall problem in three dimensions, with the structural part modeled by a 2D Kirchhoff-Boussinesq plate and the acoustic part subjected to boundary damping. The existence of a continuous nonlinear semigroup associated with the model in the finite energy space is investigated, showing that the continuity of the semigroups depends on the support of the boundary damping. The complications arise from the supercritical nonlinearity of the plate and the compromised boundary regularity of the acoustic waves.

Summary: Explored methylation dynamics of chemoreceptors in Escherichia coli in the presence of varying chemoattractant environments. Found that methylation level is sensitive to receptor cluster size and gradient strength. Short runs lead to demethylation, while long runs have varied effects depending on receptor cooperativity or gradient strength.

Summary: Different explanations were explored for induced forgetting of pictures, but none could comprehensively explain both the new analyses and previous data. Discussions were focused on aspects of forgetting theories consistent with the novel analyses and existing data, proposing future directions, and considerations when incorporating memorability into memory models.

Summary: This study discusses the magnetic behavior of metallic barcode nanowires (BNWs) and the influence of geometrical parameters on their interactions. By controlling the current densities and electrodeposition time, the size of the nanowires can be regulated. The study reveals that the effect of weak magnetism in Au segments on the interaction field between nanowires differs depending on the length of the segments. Micromagnetic simulations discover three types of magnetostatic interactions in the BNW arrays.

Summary: The strongest constraints on interactions of an axionlike particle come from coupling to a pair of SU(2)(L) gauge bosons. Couplings to U(1)(Y) and SU(3)(C) gauge bosons and to fermions are more loosely constrained.

Summary: Microorganisms play a vital role in biogeochemical cycles and interact with plastic debris. This study examined the interaction between bacteria and nano- and microplastics, finding that the diameter of the plastic particles influenced their effects on bacterial growth and viability. Smaller particles (60 nm) were observed to enter the cells and enhance the generation of reactive oxygen species, while unexpectedly, particles similar in size to the bacterial cells (1040 nm) had the greatest inhibitory effect. The bacteria also formed biofilm complexes in response to exposure to 1 μm-diameter particles.

Summary: This paper proposes using Pauli energy-based indexes to simultaneously identify strong covalent bonding and weak noncovalent interactions. The qualitative and quantitative results from this study solidify the viewpoint that a unified approach to simultaneously identify both strong and weak interactions is possible. This work signifies one step forward towards establishing a density-based theory of chemical reactivity in density functional theory.

Summary: Poly amidoamine grafted composites were proposed as enrichment adsorption materials for the rapid and efficient adsorption of N-phosphoryl dipeptide. Controllability of surface functional groups and adsorption capacities of the composites were achieved by varying the generations of poly amidoamine dendrimers. Under optimized conditions, high selectivity and recovery efficiency were obtained, demonstrating good reproducibility in practical samples.

Summary: A flexible nanocomposite composed of bacterial cellulose (BC) and gold nanoparticles (AuNPs) was developed as a SERS substrate for the sensitive and rapid detection of thiram residues on apple surface. The SERS substrate showed a high enhancement factor and a good linear correlation, with a detection limit satisfying regulatory requirements. This BC-based SERS substrate demonstrated excellent analytical performance and is suitable for the quantitative analysis of pesticides on food surfaces.
