This paper proposes an adaptive neural predictive controller to guide a nonholonomic mobile robot during trajectory tracking. The structure of the controller consists of two models that describe the kinematics and dynamics of the mobile robot system and a feedforward neural controller. The models are modified Elman neural network and feedforward multi-layer perceptron respectively. The modified...

during fixation of a femoral neck fracture in a 23-year-old male patient with cannulated screws, a broken guide wire fragment inadvertently advanced through the hip joint and protruded into the pelvis. a second surgical approach was needed to remove the broken fragment from the pelvis. awareness of such a potentially devastating complication will make surgeons more cautious during implementatio...

In light of the multitude of new Cas9-mediated functionalities, the ability to carry out multiple Cas9-enabled processes simultaneously and in a single cell is becoming increasingly valuable. Accomplishing this aim requires a set of Cas9-guide RNA (gRNA) pairings that are functionally independent and insulated from one another. For instance, two such protein-gRNA complexes would allow for concu...

Interaction and collaboration between humans and intelligent machines has become increasingly important as machine learning methods move into real-world applications that involve end users. While much prior work lies at the intersection of natural language and vision, such as image captioning or image generation from text descriptions, less focus has been placed on the use of language to guide ...

STUDY DESIGN Cadaveric study. PURPOSE The purpose of this study was to assess the accuracy and feasibility of cervical pedicle screw (CPS) insertion into the subaxial cervical spine placed using a patient-specific drill guide template constructed from a stereolithographic model. OVERVIEW OF LITERATURE CPS fixation is an invaluable tool for posterior cervical fixation because of its biomecha...
