INTRODUCTION Sialadenoma papilliferum (SP) is a rare benign tumor, which originates from the minor salivary gland. It occurs at sites that have minor salivary glands, such as the palate, retromolar pads, buccal mucosa, and lips. The most common location for tumor development is on the hard palate. A differential diagnosis consists of ruling out other salivary gland tumors. Transoral robotic sur...

The paper considers control of an autonomous underwater vehicle (AUV) with a reduced number of actua-tors. A nonlinear model describing both the dynamics and the kinematics of an AUV is studied. A continuous periodic time-varying feedback law is presented. It is shown that it exponentially stabilizes the total AUV model using only four actuators. Furthermore, it is shown that if the hydrodynami...

Background: Transoral endoscopic head and neck surgery (eHNS), including transoral laser microsurgery (TLM) and transoral robotic surgery (TORS), provides access to subsites in the head and neck that have traditionally been difficult to approach. Minor salivary gland tumors, while relatively uncommon, are frequently malignant and can occur at sites in the oropharynx accessible by transoral eHNS...

OBJECTIVES/HYPOTHESIS The transoral robotic approach to parapharyngeal space (PPS) tumors is a new technique with limited data available on its feasibility, safety, and efficacy. We analyzed our experience with transoral robotic excisions of PPS tumors to evaluate the safety and efficacy of this technique. STUDY DESIGN Retrospective chart analysis at tertiary academic medical center. From Jul...

The torI gene has been identified by using a genetic multicopy approach as a negative regulator of the torCAD operon that encodes the trimethylamine N-oxide reductase respiratory system in Escherichia coli. The negative effect was due to a previously unidentified small ORF (66 aa) of phage origin that we called torI for Tor inhibition. Overexpression of torI led to an 8-fold decrease of the tor...

Dr Byrd and colleagues have published a cost-effectiveness analysis of transoral robotic surgery (TORS) in patients with an unknown primary. Using “proportion of primary sites identified” as the marker of effectiveness, the authors examine 3 strategies: evaluation under anesthesia (EUA) and tonsillectomy, EUA/tonsillectomy followed by TORS base-of-tongue resection (sequential EUA/TORS), and EUA...

This paper describes a technique for the design oftwo-signal four-quadrant multipliers, Iiiear on both inputs and use-ful from dc to an upper frequency very close to the -f~of the transis-tors comprising the circuit. The precision of the product is shown tobe limited primarily by the matchmg of the transistors, particularlywith reference to emitter-junction areas. Expression...

We have developed a planner for redundant manipula-tors that is fast, eeective and versatile, based on the idea of treating each link of a rigid-linked robot as if it were slightly exible and under the innuence of a potential eld. We describe the extensions to the basic method that allow it to plan paths for manipulators with revolute joints (linear and spherical joints having been covered in a...
