In this paper, we propose an automatized Endoscopic Camera Manipulator (ECM) system for da Vinci surgical robot system to relieve surgeon's load in surgery. We also perform a simulation of the ECM motion planning as a basic step for automatized ECM system. We can obtain the motion trajectories of the ECM that make end effector of the ECM to reach a desired target position. We consider the ECM as a four-joint robot arm system and use the RRT (Rapidly-Exploring Random Tree) planning algorithm for this high order joint system. The simulation works properly and it will be helpful in proceeding further research.

By utilizing a 966 nm near infrared laser as an excitation light for resistance switching, we demonstrated memristive states in a two-terminal planar device based on a vanadium dioxide thin film. Before stimulating the device with 966 nm laser pulses, the device was thermally biased at ～71.5℃. Six multi-states of the device resistance could be obtained in the fabricated device by five consecutive laser pulses with 10 ms duration and increasing power, and the resistance fluctuation level was within 2.2% of the stabilized resistance and decreased down to less than 0.9% of the stabilized resistance 5 s after the illumination.

The prediction of preterm delivery is very important for investigating risk factors for preterm birth and initiating risk specific treatment but still remains a challenge for obstetricians. Based on the fact that the characteristics of unterine muscle activities change as pregnancy progresses, many researchers have tried to use noninavise Electrohysterogram (EHG) for separating the preterm and term delivery. To investigate novel and useful features to classify the preterm and term delivery groups, we randomly selected 40 records from Physionet EHG database. The records were classified into four groups depending on the time of recording (before or after the 26th week of gestation) and the length of gestation (term delivery: 1048725 37 weeks of pregnancy duration or preterm delivery: © Springer International Publishing Switzerland 2014.

In this study, we developed a sleep posture estimation algorithm using 3-axis accelerometer signals measured from a patch-type sensor. Firstly, we inspected the characteristics of accelerometer signals for different sleep postures. Based on the results, we established decision rules to estimate 5 postures containing supine, left, right lateral, prone postures, and non-sleep postures such as sitting and standing. The algorithm was tested by the data from thirteen subjects during night time PSG. As a result, the algorithm estimated sleep postures with an average agreement of 99.16%, and cohen's kappa of 0.98 compared with reference sleep postures determined by position sensor and video recording. The proposed method with the device could be used as supportive purpose in routine PSG study and out-of-hospital environment.

We describe the clinical ethics problem of American thyroid cancer patients being offered ‘observation’ instead of the USA standard of care with questionable informed consent. This problem arose because some American practitioners misinterpreted 1990s Japanese studies. American proponents of these studies failed to recognize major differences in ethical oversight between Japanese and US clinical research, misrepresenting these studies as justifying clinical practices for higher risk patients that were not supported by data. The current professional environment in American thyroid cancer management is sufficiently problematic that consideration should be made, for patients who have inadvertently consented to nonevidence-based treatments, to be recontacted and provided an opportunity to revisit their care plans or seek second opinions regarding an observational approach.

and T1assessment of abdominal tissue response to graded hypoxia and hypercapnia using a controlled gas mixing circuit for small animals

Purpose To characterize and T 1 relaxation time response to a wide spectrum of gas challenges in extracranial tissues of healthy rats. Materials and Methods A range of graded gas mixtures (hyperoxia, hypercapnia, hypoxia, and hypercapnic hypoxia) were delivered through a controlled gas-mixing circuit to mechanically ventilated and intubated rats. Quantitative magnetic resonance imaging (MRI) was performed on a 3T clinical scanner; and T 1 maps were computed to determine tissue response in the liver, kidney cortex, and paraspinal muscles. Heart rate and blood oxygen saturation (SaO 2 ) were measured through a rodent oximeter and physiological monitor. Results decreases consistent with lowered SaO 2 measurements were observed for hypercapnia and hypoxia, but decreases were significant only in liver and kidney cortex ( P < 0.05) for >10% CO 2 and <15% O 2 , with the new gas stimulus, hypercapnic hypoxia, producing the greatest decrease. Hyperoxia-related increases were accompanied by negligible increases in SaO 2 . T 1 generally increased, if at all, in the liver and decreased in the kidney. Significance was observed ( P < 0.05) only in kidney for >90% O 2 and >5% CO 2 . Conclusion and T 1 provide complementary roles for evaluating extracranial tissue response to a broad range of gas challenges. Based on both measured and known physiological responses, our results are consistent with as a sensitive marker of blood oxygen saturation and T 1 as a weak marker of blood volume changes. J. Magn.
