Physics of Particles and Nuclei 2025年第2期56卷 330-334页

作者： Galkin, V.O. Savchenko, E.M. Federal Research Center Computer Science and Control Russian Academy of Sciences Moscow 119333 Russian Federation Faculty of Physics Moscow State University Moscow 119991 Russian Federation

Abstract: Masses of ground states of triply heavy tetraquarks are calculated within the relativistic quark model based on the quasipotential approach and the diquark–antidiquark picture of tetraquarks. The relativistic diquark–antidiquark interaction quasipotential takes into account the internal structure of the diquark and antidiquark and all relativistic corrections. The calculated masses are compared to fall-apart decay thresholds into a meson pair, and conclusions are drawn about the possibility of detecting such states. © Pleiades Publishing, Ltd. 2025.

Iron is a fundamental trace element essential for the immune system， and current research on iron supplements is increasingly focusing on food-derived peptides capable of binding iron ions. The objectives of this study were to characterize the iron-chelating peptide (MEPH) derived from Mytilus edulis and to investigate the effects of MEPH-Fe complexes on mice with iron deficiency-induced anemia (IDA). MEPH and iron(II) sulfate heptahydrate successfully formed MEPH-Fe complexes under conditions of 4.5 mg/mL concentration， 45 ℃ temperature， and 60 minutes of incubation， utilizing both carboxyl and amino binding sites. Compared to MEPH alone， the MEPH-Fe complexes exhibited fluorescence quenching， ultraviolet shifts， reduced X-ray diffraction peak intensities， stabilization during in vitro digestion， microstructural changes， increased particle size， and decreased absolute values of zeta potential. In the IDA mouse model， the MEPH-Fe complexes were able to restore body weight， hematological indices， organ coefficients， iron content in organs， and antioxidant capacity to normal levels. Additionally， they demonstrated beneficial effects on IDA-induced colonic inflammation by normalizing tumor necrosis factor-alpha (TNF-α) and interleukin-10 (IL-10) levels. The results indicated that MEPH-Fe complexes had more positive effects on IDA mice compared to ferrous sulfate. In conclusion， this study provides valuable insights into the potential of MEPH-Fe complexes as iron supplements.

RoG-SAM: A Language-Driven Framework for Instance-Level Robotic Grasping Detection

引用

IEEE Transactions on Multimedia 2025年 27卷 3057-3068页

Robotic grasping is a crucial topic in robotics and computer vision, with broad applications in industrial production and intelligent manufacturing. Although some methods have begun addressing instance-level grasping, most remain limited to predefined instances and categories, lacking flexibility for open-vocabulary grasp prediction based on user-specified instructions. To address this, we propose RoG-SAM, a language-driven, instance-level grasp detection framework built on Segment Anything Model (SAM). RoG-SAM utilizes open-vocabulary prompts for object localization and grasp pose prediction, adapting SAM through transfer learning with encoder adapters and multi-head decoders to extend its segmentation capabilities to grasp pose estimation. Experimental results show that RoG-SAM achieves competitive performance on single-object datasets (Cornell and Jacquard) and cluttered datasets (GraspNet-1Billion and OCID), with instance-level accuracies of 91.2% and 90.1%, respectively, while using only 28.3% of SAM's trainable parameters. The effectiveness of RoG-SAM was also validated in real-world environments. A demonstration video is available at https://***/playlist?list=PL7et4nGJAImLGytsJbglGbXl1hacA2dy. © 1999-2012 IEEE.

Detecting the openable parts of articulated objects is crucial for downstream applications in intelligent robotics, such as pulling a drawer. This task poses a multitasking challenge due to the necessity of understanding object categories and motion. Most existing methods are either category-specific or trained on specific datasets, lacking generalization to unseen environments and objects. In this paper, we propose a Transformer-based Openable Part Detection (OPD) framework named Multi-feature Openable Part Detection (MOPD) that incorporates perceptual grouping and geometric priors, outperforming previous methods in performance. In the first stage of the framework, we introduce a perceptual grouping feature model that provides perceptual grouping feature priors for openable part detection, enhancing detection results through a cross-attention mechanism. In the second stage, a geometric understanding feature model offers geometric feature priors for predicting motion parameters. Compared to existing methods, our proposed approach shows better performance in both detection and motion parameter prediction.

This paper considers the optimal control problem of steering a Dubins vehicle with a decaying speed that depends linearly on the turn-rate to a terminal point and heading with maximum kinetic energy. Pontryagin’s minimum principle is applied and the extremals are identified as sequences of straight segments and spiral-shaped turns described by involutes of a circle. A method is proposed to exactly transcribe the optimal control problem into a series of finite dimensional optimizations. Each of these optimizations determines a locally optimal candidate path that reaches the terminal state. The lowest cost path among the candidate paths is then identified. The approach is demonstrated through several numerical examples. © 2025, American Institute of Aeronautics and Astronautics Inc, AIAA. All rights reserved.
