Summary: The bead foaming process of semicrystalline polymers is complex, influenced by the formation of multiple crystalline populations that ensure the structural integrity of beads while allowing sintering. The quality of the double melting peak structure is related to the temperature, duration of treatment, and quenching rate. Fast-scanning calorimetry can reproduce conditions for optimal quenching rates in isotactic polypropylene (iPP).

Summary: There is a growing trend in using saliva for SARS-CoV-2 detection with reasonable accuracy. A study comparing disease with control using Fourier transform infrared (FTIR) spectra analyzed the responses of IgA, IgG, and IgM in human saliva by employing two-trace two-dimensional correlation spectra (2T2D-COS). The study revealed molecular-level variation between control and COVID-19 saliva samples, showing a decrease in salivary antibodies and lipids in COVID-19 samples. It also found that saliva thiocyanate plays a defense mechanism against SARS-CoV-2 in certain male age groups.

Summary: Resolving the single-crystal structures of two-dimensional covalent organic frameworks (2D COFs) is a challenging task. In this study, the authors investigate the growth process of 2D COFs by tracing growth intermediates and identify two different growth mechanisms. This enables the growth and structure determination of micron-sized 2D single-crystalline COFs.

Summary: In this paper, we investigate the two-dimensional random field Ising model with mean zero Gaussian variables and variance 2. We analyze the correlation length, which represents the critical box size where the random field and boundary condition have comparable effects on spin magnetization. Our results show that the correlation length scales exponentially as e,⠂4=3/ as 0, and our upper bound is applicable for all positive temperatures.

Summary: This study compared the immune response in saliva associated with COVID-19 using two-dimensional correlation spectroscopy (2DCOS) and receiver operating characteristic (ROC) analysis, which has potential for non-invasive monitoring of the disease. The results showed biomolecular changes related to SARS-CoV-2 and demonstrated high sensitivity and specificity, confirming the effectiveness of this method in COVID-19 diagnosis.

Summary: The reduced cost of pesticide use in agricultural production leads to increased usage, resulting in serious threats to the aquatic environment. Fishes, as bioindicators of toxicants in the water, provide valuable information about the aquatic biota. The study of pesticide toxicity in fish is important for understanding and assessing the impact of pollution in the ecosystem.

Summary: The study compared the FTIR spectra characteristics of human saliva with their biochemical composition, showing strong correlations between absorption bands and specific components. The correlations were found to be gender-dependent. By identifying potentially informative combinations of absorption bands, the study expanded the interpretation possibilities of FTIR spectra in biomedical applications.

Summary: This study aims to examine the complexity of underlying dynamics of various ocean data using nonlinear time series analysis techniques, and validates the potential of these techniques for characterizing ocean data variability. One-year data from an offshore platform and two-year data from a weather buoy were collected and analysed, and the results indicate that all the ocean data considered here exhibit chaotic characteristics in the reconstructed phase space. The surface currents speed shows the highest fractal dimension and correlation dimension, while the significant wave height has the lowest values, suggesting that the dynamics associated with surface currents speed tend to be the most complex.

Summary: This study revisits the Grassberger-Procaccia algorithm and introduces an extremely simple estimator of the correlation dimension. Guidelines are provided on determining the extent to which the correlation dimension may be underestimated, given the size of the data and the dimensionality of the state space. The new estimator, along with established intrinsic dimension calculations, is applied to detect causal relationships using a challenging example of coupled chaotic oscillators.

Summary: We introduce a family of dimensions called the Phi-intermediate dimensions, which generalize the intermediate dimensions introduced by Falconer, Fraser and Kempton and lie between the Hausdorff and box dimensions. This is achieved by restricting the relative sizes of the covering sets to allow for greater refinement. We extend the theory from Euclidean space to a wider class of metric spaces and prove that these dimensions can be used to recover the interpolation between the Hausdorff and box dimensions of compact subsets.

Summary: Research on nanocrystals synthesized in solution is driven by their unique physical properties determined by sizes and shapes. However, the limited understanding of crystallization, particularly the prevalence of noncrystalline intermediates, poses a challenge. In situ X-ray scattering reveals that the nucleation and growth of nanocrystals are constrained within amorphous intermediates, which play a crucial role in determining the final crystal characteristics and size.

Summary: In this study, we explore the non-local correlation dynamics in a two-dimensional honeycomb lattice of disordered electrons in a Graphene sheet. The results show that the lattice-point interaction affects the Bell-function non-locality and entanglement concurrence, and the uncertainty-induced non-locality correlation is more stable than the Bell non-locality and concurrence.

Summary: In this study, we investigate the nth-order correlation functions of Tonks-Girardeau (TG) gases, and obtain the exact ground state wavefunction of TG gases using the wavefunction of free fermions and Bose-Fermi mapping method. By utilizing the properties of Vandermonde determinant and Toeplitz matrix, we formulate the nth-order correlation function as an (N-n)-order Toeplitz determinant, whose element can be computed analytically. We derive concise formulas for the reduced two-body and three-body density matrices and discuss their properties. It is demonstrated that in successive measurements, atoms appear in the regions with the maximum probability of atomic occupation in the first measurement.

It shows that using geodetic and Euclidean metrics results in different biases through two analytically tractable cases. The analysis provides a cue for studying fractal geometries in seismology.

The modified waste rubber powder showed significant enhancement in mechanical properties, leading to a significant increase in tensile strength and elongation at the break of the composite hydrogel.

Summary: We propose a simple and rapid strategy to fabricate self-crosslinked dual-crosslinking elastomers with high mechanical properties. The elastomers are synthesized through one-pot copolymerization and consist of dual-network crosslinking with hydrogen bonds and Si-O-Si covalent bonds. These two crosslinking networks contribute to the mechanical properties and recoverability of the elastomers.

Summary: Compliant and tough poly (hydroxyethyl methacrylate) (PHEMA)-based hydrogels were developed with enhanced hydrogen bond-reinforcing interactions and phase separation inhibition by introducing maleic acid (MA) units. These hydrogels demonstrated high tensile strength, fracture strain, tensile modulus, and toughness, as well as good compliance comparable to silicone breast prosthesis. They also exhibited excellent self-recovery ability and fatigue resistance. Cellular and animal experiments confirmed their biocompatibility and stability, suggesting their potential as an alternative implant material for breast reconstruction.
