Summary: Regenerative periodontal surgical procedures are important for improving the long-term prognosis of teeth affected by advanced periodontitis. They involve the formation of root cementum, periodontal ligament, and alveolar bone, resulting in reduced pocket depths and improved furcation depth. Close attention to patient, tooth/defect, and operator factors is crucial for treatment success and prevention of complications. This article provides an overview of these factors and offers recommendations based on clinical practice guidelines and expert opinion.

Summary: The study evaluated the effects of cross-linked hyaluronic acid (xHyA) with or without a collagen matrix (CM) on periodontal wound healing in class III furcation defects in dogs. The results showed that xHyA and xHyA/CM groups had larger new bone areas and greater formation of new connective tissue attachment compared to the OFD and CM groups. However, complete furcation closure was not achieved in any of the treatment modalities.

Summary: Generalized zero-shot learning aims to recognize both seen and unseen samples by leveraging the connections between semantic and visual representations. However, there is a considerable gap between generated features and real unseen features, leading to misclassification. To address this issue, we propose a dual-aligned feature confusion alleviation framework that generates faithful and discriminative features for unseen categories. Experimental results show that our method outperforms previous state-of-the-arts and successfully alleviates features confusion problem in GZSL.

Summary: Many current research works on cross-modal retrieval of video and text aim to reduce the semantic gap, but fail to consider the semantic difference between frames in the same video and the correlation of feature distribution in different frames. To address this, a pre-trained video frame classification-aggregation network is used to make object categories in different frames closer to the important object categories in the whole video. Then, a video internal frame aggregation loss module is proposed to enhance the feature representation of video sampled frames. Experimental results demonstrate the effectiveness of the proposed approach on three common datasets.

Summary: A design approach for a triple-mode resonant feed antenna is proposed for a parabolic reflector antenna system. The antenna consists of a slit-loaded 1.5-wavelength sectorial dipole, a primary corner reflector, and an auxiliary circular reflector. The corner angle of the primary reflector can be adjusted to narrow down the H-plane half-power beam width (HPBW), while the E-plane is minimally affected, resulting in equal E-/H-plane characteristics. High-order resonant modes are used to generate an inverse taper radiation pattern at the high frequency band. Numerical and experimental results confirm that the optimal corner angle of the primary reflector is 45 degrees. The antenna exhibits an impedance bandwidth of up to 79.7% and an almost equal E-/H-plane bandwidth of up to 29.4%. Within this bandwidth, it achieves an average HPBW of approximately 65 degrees, a gain of up to 8.9 dBi, and a fluctuation of less than 1 dB. The inverse taper radiation pattern at the high frequency band allows for effective edge illumination and uniform aperture field distribution in parabolic reflector antenna systems.

Summary: Zero-shot Learning (ZSL) aims to recognize novel classes through seen knowledge. Existing approaches often overlook fine-grained information, leading to sub-optimal knowledge transfer between seen and unseen classes. To address this issue, we propose a Language-Augmented Pixel Embedding (LAPE) method that bridges the visual and semantic spaces in a pixel-based manner.

Summary: This article discusses a more difficult yet more practical source-free transfer setting, where there are only the models pretrained in source domain and limited target data can be available. To address the challenges of the absence of source data and distribution discrepancy in cross-domain SOC estimation, a novel source-free temperature transfer network (SFTTN) is proposed, which can mitigate domain shift adaptively. Experiment results indicate that SFTTN can achieve robust and accurate SOC estimation at different ambient temperatures under source-free scenario.

Summary: Difunctionalizing carboxylation of alkynes with CO2 is a sustainable and important strategy to generate valuable acrylate derivatives from readily available starting materials. This study introduces a visible-light-driven and transition metal-free thio-carboxylation of alkynes with thiophenols and CO2. The use of single-electron activation of CO2 leads to unique beta-carboxylation, followed by efficient cyclizing acylation to obtain important thiochromones. The one-pot method features mild reaction conditions, high selectivity, scalability, and facile derivatization of products to bioactive compounds.

Summary: In this paper, the authors propose a novel method called Classification Certainty Maximization (CCM) for unsupervised domain adaptation (UDA). CCM considers both the joint certainty between classifiers and the individual certainty of each classifier to optimize weight ratios. Additionally, a dynamic centroid update strategy is proposed to mitigate domain gaps at the feature level. Experimental results on four widely used UDA datasets demonstrate that CCM outperforms existing state-of-the-art domain adaptation methods. The dynamic centroid update strategy can also be used as a plug-and-play module to boost classification accuracy in existing bi-classifier domain adaptation methods.

Summary: The crystal structure-dielectric property relationship of combustion-made BaTiO3 nanocrystals was investigated. Nanocrystals with sizes below 100 nm exhibited a metastable paraelectric cubic phase, while sizes above 200 nm had a stable ferroelectric tetragonal phase. Annealing the tetragonal nanocrystals produced single crystals with higher dielectric constants. However, the absence of 90 degrees domains in the single crystals resulted in a low dielectric constant.

Summary: In this study, it is demonstrated that 1,3-dienes form p-Lewis base-activated electron-neutral and HOMO-raised ?(2)-complexes with Pd(0), which undergo protonation with various acidic sources. The resulting p-allyl palladium complexes then undergo the amination reaction to give the final products. The mechanistic proposal is supported by FMO and NPA analyses, control experiments, and the development of an efficient Pd(0)-mediated hydroamination reaction.

Summary: This paper introduces semi-supervised feature selection methods that utilize both labelled and unlabelled samples. It proposes a novel model called Semi-supervised Feature Selection with Binary Label Learning (SFS-BLL) which learns binary hash codes as pseudo labels and uses a self-weighted sparse regression module to guide the feature selection process. An effective discrete optimization method based on the Alternating Direction Method of Multipliers (ADMM) is developed to optimize the binary labels and feature selection matrix iteratively. Extensive experiments demonstrate the superiority of the proposed method.

Summary: As a promising approach in translational medicine, the decellularization of discarded livers to produce bioscaffolds that support recellularization has potential in overcoming the limitations of conventional liver transplantation. In this study, the researchers investigated the use of matrix metalloproteinase (MMP) inhibition to preserve the extracellular matrix (ECM) during liver decellularization. The results demonstrated that the application of an MMP inhibitor significantly improved the preservation of ECM components and mechanical properties of the bioscaffolds, which supported cell viability and function in vitro. The study also confirmed that the MMP inhibition led to the inhibition of MMP2 and MMP9, providing a novel method to enhance ECM preservation during liver decellularization.
