Morphometric Study on the Mandible of Colobine Fossil (Mesopithecus pentelicus) Found in East Asia, a Comparison With Extant Taxa.

A tooth-bearing mandible fossil of a colobine monkey discovered at Shuitangba, Zhaotong, Yunnan, China, was morphometrically analyzed and compared with extant Asian colobines. Our previous qualitative and quantitative descriptions indicate that it can be safely attributed to Mesopithecus pentelicus, a Miocene fossil colobine widely found in Europe and South Asia. The present research aims to explore fossil association with extant colobines and functionally propose its dietary preferences based on multivariate morphometric analyses of mandibular morphology.

Path planning for flexible needle based on both insertion mechanism kinematics and needle bending model.

Objective: Due to the limited operating space in the magnetic resonance (MR) environment, there is coupled motion in the insertion mechanism, which not only reduces the flexibility of the robot but also challenges the insertion path planning. Meanwhile, the path planning is also restricted by the bending rule of the flexible needle, thus the bending model of the needle is also essentially built.

Approach: This paper proposes a path planner for the flexible needle based on both the coupled motion kinematics of the insertion robot and the bending model of the flexible needle.

Proximity hybridization-triggered cascade amplification for label-free SERS detection of Alzheimer's amyloid-β oligomers.

Most of the existing SERS systems failed to achieve satisfactory results in early diagnosis of Alzheimer's disease owing to a lack of effective signal transduction. Herein, we developed a dual signal amplification strategy for SERS detection of amyloid-β oligomers based on proximity hybridization-triggered catalyzed hairpin assembly (CHA) and hybridization chain reaction (HCR). In the presence of the target protein and two DNA-labeled antibodies, a proximate complex formed in a homogeneous solution.

A Legendre Neural Network-Based Approach to Multiparameter Identification of Traffic Loads Across the Full Spatiotemporal Domain.

The accurate identification of traffic loads acting on bridges provides an effective basis for the traffic control and operation of in-service bridges. To improve the efficiency and accuracy of loading identification, we propose an efficient multiparameter identification method with a Legendre neural network (LNN) for the monitoring of traffic loads across the full spatiotemporal domain. Compared to conventional studies that suffer from ill-posed problems and neural network-based means that lack a physically interpretable model, with the proposed strategy, both the explicit expression and time histories of the traffic load can be simultaneously obtained.

Short-range azimuth measurement method based on a single-pulse laser beam expanding mechanism.

Aimed at addressing the problem of azimuth measurement of a short-range target with a pulsed laser, a new, to our knowledge, azimuth measurement method based on a single-pulse laser beam expanding mechanism is proposed based on the research of the pulse laser dynamic/static azimuth detection method. The echo power equation of single-pulse laser beam expanding short-range detection is derived theoretically. Combined with the spatial geometric distribution of the optical path and the normalized sum-difference angle measurement algorithm of the four-quadrant detector, a single-pulse laser short-range azimuth angle calculation model is established.

Reassessing the Role of Thermal Convection in Simultaneous Water Production and Pollutant Degradation in Interfacial Photothermal-Photocatalytic Systems.

The interfacial photothermal-photocatalytic systems can generate clean water while purifying wastewater containing organic pollutants, but the impact of thermal convection on synergistic effects remains unexplored. This paper aims to regulate the thermal convection at the interface to significantly enhance the synergistic effect of interfacial photothermal-photocatalytic systems. A novel heterogeneous structure comprising iron-based metal-organic frameworks and multi-walled carbon nanotubes with a gelatin-polyvinyl alcohol (PVA) double network hydrogel (MWCNTs@NM88B/PVA/gelatin hydrogel, denoted as MMH) is developed and employed in the construction of the solar-driven interfacial evaporation (SIE) system.
