Kinematics of Stratified Vision-Based Manipulation

Anekdote zur Senkung der Arbeitsmoral (1963)

第十一届IFTOMM世界大会

作者： Yejun Wei b.ll goodwine Steven b. Skaar University of Notre Dame University of Notre Dame University of Notre Dame

＜正＞This paper addresses two kinematics problems associated with the application of camera-space manipulation to stratified robotic manipulation. The first one is to characterize the pose of a three-dimensional object by the image information of the visual features randomly attached to the object. The second one is to calibrate the kinematics model of multiple robots via computer vision, which is a difficult problem that camera-space method itself can avoid when applied to robotic manipulation. A general method is presented to determine the pose of an object based on the object’s visual features image information. Experiments on a b.ll and a cube object are carried out to verify that method. The experiment results related to the b.ll are presented.

AIM： To investigate the prevalence and clinical significance of ＂anti-Hbc alone＂ in an unselected population of patients and employees of a university hospital in southern Germany. METHODS： All individuals with the pattern ＂anti-Hbc alone＂ were registered over a time span of 82 mo. HbVDNA was measured in serum and liver samples, and clinical charts were reviewed. RESULTS： Five hundred and fifty two individuals were ＂anti-Hbc alone＂（of 3004 anti-Hbc positive individuals; 18.4%）, and this pattern affected males （20.5%） more often than females （15.3%; P〈0.001）. HbV-DNA was detected in serum of 44 of 545 ＂anti-Hbc alone＂ individuals （8.1%）, and in paraffin embedded liver tissue in 16 of 39 patients tested （41.0%）. There was no association between the detection of HbV genomes and the presence of biochemical, ultrasonic or histological signs of liver damage. Thirty-eight ＂anti-Hbc alone＂ patients with cirrhosis or primary liver carcinoma had at least one additional risk factor. HCV-coinfection was present in 20.4% of all individuals with ＂anti-Hbc alone＂ and was the only factor associated with a worse clinical outcome. CONCLUSION： In an HbV low prevalence area, no evidence is found that HbV alone causes severe liver damage in individuals with ＂anti-Hbc alone＂. Recommendations for the management of these individuals are given.

AIM： To investigate the antiviral effect of beta-L- enantiomer of 2;3＇-didehydro-2＇,3″-dideoxyadenosine （13-L-D4A） on 2.2.15 cells transfected with the hepatitis b virus （HbV） genome.METHODS： Lamivudine （3TC） as a positive control. Then, HbV DNA in treated 2.2.15 cells and the Hepatitis b surface antigen （HbsAg） in the culture supernatants were detected to determine the inhibitory effect of β-L- D4A. At the same time, 3-（4,5-dimethylthiazol-2-yl）-2,5- diphenyltetrazolium bromide （MTT） was used to detect the survival ratio of 2.2.15 cells.RESULTS： β-L-D4A has a dose-dependent inhibitory effect on HbV DNA replication; this effect was apparent when the concentration was above 1 mol/L. When β-L- D4A was at the highest concentration, 100 mol/L, the HbsAg inhibition ratio was above 50%. The Therapeutic index （TI） of β-L-D4A was above 2.1.CONCLUSION： β-L-D4A has a dose-dependent inhibitory effect on the replication of HbV DNA and the secretion of HbsAg at low toxicity,

The role of grain-boundary (Gb) in the melting for Sigma=5 bicrystals of b2 NiAl is investigated by molecular-dynamics simulation. The thermodynamic properties of the boundary are monitored over a wide temperature range including the thermodynamic melting point T-m which is determined by using a many-body potential fitted to NiAl. A thermal disorder transition in the Gb region occurs well below the melting point. Our results indicate that such a transition is a continuous process and there is no evidence of premelting, which is entirely in accord with experimental results and theoretical prediction. Moreover, we also find that the superheated temperature range of this intermetallic alloy is much wider than that of some elemental metals.

Localized surface plasmon resonance(LSPR)biosensing based on supported metal nanoparticles offers unparalleled possibilities for high-end miniaturization,multiplexing and high-throughput label-free molecular interaction analysis in real time when integrated within an opto-fluidic ***,such LSPR-sensing devices typically contain extremely large regions of dielectric materials that are open to molecular adsorption,which must be carefully blocked to avoid compromising the device *** address this issue,we made the support essentially invisible to the LSPR by carefully removing the dielectric material overlapping with the localized plasmonic fields through optimized *** resulting LSPR substrate,which consists of gold nanodisks centered on narrow SiO2 pillars,exhibits markedly reduced vulnerability to nonspecific substrate adsorption,thus allowing,in an ideal case,the implementation of thicker and more efficient passivation *** demonstrate that this approach is effective and fully compatible with state-of-the-art multiplexed real-time biosensing technology and thus represents the ideal substrate design for high-throughput label-free biosensing systems with minimal sample consumption.

From the radix of Pueraria peduncularis Grah., two new oleanene-type triterpenoid saponins named pedunsaponins b (2) and C (3) were isolated. Their structures were determined as 3-O-(6-O-methyl)-beta-D-glucuronopyranosyl-3 beta.15 alpha-diol-12-oleanene-16-one (2) and 3-O-beta-D-glucopyranosyl-( 1 --> 3)-beta-D-glucuronopyranosyl-3 beta, 15 alpha-diol-12-oleanene-16-one (3) on the basis of spectroscopic evidence and chemical reactions.
