Summary: This paper presents a general synthesis method for 1-DOF single-loop mechanisms (SLMs) by dividing the mechanism into a revolute pair and a branch chain. The method designs several kinematic pairs in the branch chain without constraining the rotation of the revolute pair. The synthesis schemes corresponding to the constraints are formulated, and deployable and symmetrical SLMs are constructed.

Summary: This study explores various design concepts for foldable shelters, presenting and analyzing shelter forms inspired by the geometric attributes of origami. Rigorous mathematical models and CAD modeling are used to evaluate and compare thin-walled and thick-walled shelter concepts. The results demonstrate the applicability of compound folding patterns in thick-walled origami-inspired shelters, and the dependence of erection torque on application location and transition process.

Summary: This article introduces a small hybrid aerial underwater vehicle called Nezha-F, which can fly in the air, perform vertical profiling underwater, and vertically take off and land from both the water surface and ground. A foldable and self-deployable arm mechanism linked to and driven by a piston variable buoyancy system (PVBS) is proposed to reduce excessive underwater drag caused by aerial structures. This design provides a feasible idea for the miniaturization of amphibious floats by having a compact size and successfully balanced aerial and underwater performance without adding excessive actuators.

Summary: This article proposes a basic deployable pyramid unit with good deployability and expandability to construct a sizeable deployable mechanism. The configuration synthesis method of adding constraint chains of spatial closed-loop mechanism is used to synthesize the basic unit. The performance characteristics of the three types of mechanisms are described in detail based on the folding motion simulation analysis. The proposed deployable mechanism provides a reference for the design and application of antennas in the aerospace field with a large aperture, high deployable rate, and lightweight.

Summary: This article introduces a novel class of 6-DOF foldable parallel mechanisms called FoldRail mechanisms, which have a circular rail allowing unlimited rotation and innovative kinematic chains for foldability. The paper presents mechanisms with three to six kinematic chains and analyzes their mobility using instantaneous screw theory to identify singularities and inappropriate actuation schemes. Among various mechanisms, two with three kinematic chains and identical actuation schemes are compared and one is further analyzed to demonstrate its reconfigurable motion and determine singular configurations.

Summary: This paper proposes a method for synthesizing reconfigurable single-loop mechanisms (RSLMs) using screw theory, and obtains four types of wrench systems of RSLMs by inserting revolute joints to a planar rhombus 4R mechanism. The reconfiguration analysis of RSLMs with a constraint force system is carried out using the kinematics close-loop equation and screw theory method, and multiple motion modes are identified. Furthermore, several 3D printed models are presented to verify the motion modes of the mechanisms.

Summary: This study presents an experimental demonstration of the motion characteristics of a comb-drive actuator fabricated from a heterogeneous structure and designed for cryogenic environments. It reveals irregular motion behaviors at specific low temperatures, which can be attributed to the different thermal expansion coefficients of the materials in the heterogeneous structure and the deformation of the support spring. It suggests that the stiffening of the support spring can effectively constrain irregular yield behavior at low temperatures.

Summary: This paper presents a coupled force-position control (CFPC) method which combines the proposed adaptive impedance control method with a modified hybrid force-position control (HFPC) method. It addresses the issues of system oscillation during switching between force and position control in traditional HFPC, as well as poor force-tracking performance in conventional impedance control. Simulation and physical experiments demonstrate that CFPC method outperforms traditional HFPC method in terms of force-tracking performance and smooth switching between position and force control.

Summary: The quality of breast ultrasound images plays a crucial role in disease diagnosis accuracy. Existing image quality assessment methods focus on global image quality and ignore the quality of the lesion region, which is important for doctors' evaluation. This study proposes a global-local integrated IQA framework for breast ultrasound images to learn doctors' clinical evaluation standards.
