Vestigial Plastids in Parasitic Plants: Evolutionary Remnants or Adaptive Innovations?

Plant, Cell &Environment, Volume 49, Issue 8, Page 5401-5420, August 2026.
ABSTRACT Throughout the evolutionary history of plants, chloroplasts originating from a cyanobacterial endosymbiosis have undergone remarkable adaptation and specialization, giving rise to a multitude of plastid types. The evolution toward parasitism in plants represents a particularly extreme case of such specialization.

Motion Retargetting and Transition in Different Articulated Figures [PDF]

Ninth International Conference on Computer Aided Design and Computer Graphics (CAD-CG'05), 2006
In this paper, we present an interactive system to transfer and concatenate motions in different articulated figures, such as human and dog. This system first constructs a union skeleton that contains both bone structures with bone correspondence manually assigned by users, and then aligns the initial poses of these two skeletons.

A Hybrid Retroperitoneal–Transperitoneal Approach for Robot‐Assisted Radical Nephrectomy: A Technical Report of Two Cases

IJU Case Reports, Volume 9, Issue 4, July 2026.
ABSTRACT Introduction Robot‐assisted radical nephrectomy (RARN) can be performed using either transperitoneal or retroperitoneal approaches; however, each has inherent limitations, particularly in cases with complex hilar anatomy or post‐systemic therapy fibrosis.

Vision-Based Hand Shadowing for Robotic Manipulation via Inverse Kinematics

IEEE Access
Teleoperation of low-cost robotic manipulators remains challenging due to the difficulty of retargeting human hand motion to robot joint commands. We present an offline hand-shadowing inverse-kinematics (IK) retargeting pipeline driven by a single ...

Delivery Systems for Therapeutic Genome Editing: Challenges, Innovations, and Future Perspectives

MedComm, Volume 7, Issue 7, July 2026.
Schematic illustration of four emerging CRISPR–Cas delivery platforms defined by distinct design principles and structural features: virus‐mimicking nanosystems (e.g., VLPs), cell‐derived extracellular vesicles, cell‐penetrating peptides, and stimuli‐responsive scaffolds. These platforms enable spatiotemporally controlled delivery of RNPs, mRNA, or DNA
