極限作業ロボットマニピュレータの設計法に関する研究 （その１） 繊細感覚多本指マニピュレータの設計法

The advanced manipulator is designed based on systematized method for hand tool operation. It has 7 D.O.F. ultra light weight arm with 4 fingered and 14 D.O.F. hand. Tactile sensors, covered by soft rubber which can keep sensing accuracy and recognize proper sensing points, are installed on finger tips and middle frames of fingers. Two force sensor cells are also assembled in each sensor. These fingers are drived by snake tube and ropes and fluid coupling connecting to AC motor actuators. Reduction gear ratio of the finger and the arm actuators is reduced in order to made force or dexterous control easier. This paper describe how the hand and arm manipulator should be designed refining its function or using advanced technology.

Vertical plane short and middle latency vestibular evoked potentials in humans.

In order to determine whether short and middle latency vestibular evoked potentials (VsEPs) can be recorded in humans in response to angular acceleration stimuli in the vertical plane, a drum, head-holder, and stepper motor were designed to deliver upward acceleration impulses of 10,000 degrees/s2 (1.8 degrees displacement) to the human head. Forehead and mastoid electrodes recorded electrical activity that was filtered, differentially amplified, and averaged in short (12.7 milliseconds) and middle (63.5 milliseconds) latency time frames. Control recordings were used to eliminate various types of artifact. Recordings were conducted in 7 normal subjects and in 4 control patients with congenital, profound hearing loss and absence of caloric responses. Short and middle latency VsEPs with high intrasubject and intersubject consistency were recorded in normal subjects and not in control patients. The middle latency responses were larger in amplitude than the short latency responses. The effects of stimulus intensity and repetition rate on VsEP waveform, latency, and amplitude studied. Experiments have shown that the responses are not electrical artifact, nor are they contaminated by auditory, somatosensory, or passive eye movement potentials.

Adjusting dysarthric speech timing using neural nets

Speech timing problems associated with dysarthria often involve the presence of periods of extraneous silence and nonspeech sounds as well as inappropriately timed or misplaced speech gestures. This study evaluated the performance of neural networks in detecting the presence of inappropriate or nonspeech sounds and extraneous silence. The “opt” neural network program [E. Barnard and R. Cole, OGC Tech. Rep. No. CSE 89‐014] that uses a conjugate gradient algorithm to adjust node weights was trained to recognize breaths and silence in a reading of the rainbow passage by a single dysarthric (Cerebral Palsy) talker. Input to the network consisted of a sequence of frames of parameters derived from spectral analysis of the speech. The output was a binary (speech/nonspeech) decision for the segment of signal corresponding to the middle frame of the input sequence. Networks of various size and configuration were trained on half the available data and tested on the remaining data. The best network configurations correctly identified approximately 99% of the frames in the training set and about 97% of the frames in test datasets.

A sixth Epstein-Barr virus nuclear protein (EBNA3B) is expressed in latently infected growth-transformed lymphocytes

In the Epstein-Barr virus BamHI E genomic fragment, there are three distantly homologous long open reading frames, BERF1, BERF2b, and BERF4, each of which is preceded by a short open reading frame. The most leftward and most rightward short and long open reading frame pairs encode 145- and 155-kilodalton proteins in latently infected cells (EBNA3A and EBNA3C, respectively). In this report, we demonstrate that the middle long open reading frame, BERF2b, encodes part of a 165-kilodalton nuclear protein in every latently infected cell. Therefore, this protein is designated EBNA3B.

Formal Networks For Women Professionals

Abstract To start such a topic as this, one could turn to a dictionary to define “networking.” Personally, I like to refer to the comics—in this instance the comic strip “Nancy”. The first frame finds Nancy, in class, turned around in her seat earnestly talking to another young colleague. In the next frame Nancy has turned in response to the teacher asking her if she was talking. Nancy replies, “Talking? No Ma'am, I'm not talking. I'm establishing contacts and exchanging information with my peers.” The middle frame shows Nancy grumbling, “OK, whatever you say… ” and the final frame of the comic shows Nancy, at her desk, busily writing “I will not network in class, I will not network in class, I will not network in class.” Yes, some of the terms may have changed, but the point is still why network or, more specifically, why join a formal network or a group that networks?

The sequence of the bacteriophage P1 genome region serving as hot target for IS2 insertion.

A restriction fragment of the bacteriophage P1 genome known to serve as a hot target for IS2 insertion in its host, Escherichia coli K12, was entirely sequenced. It is 1756 bp long and it contains four long open reading frames, all in the same orientation. The two middle frames overlap partially. Eight of the nine studied IS2 insertions affecting phage reproduction map within three of these reading frames. No common feature was found between the nine target sites which have served for IS2 integration. However, there are two structural elements which might possibly contribute to rendering the studied DNA segment a hot region for IS2 insertion. The first is formed by two neighbouring, 30 and 40 bp regions of homology with an internal segment of IS2. The second is the pentanucleotide 5' GGTAT3', which is carried nine times in the sequenced fragment and which is found always in at least one copy within a variable distance of less than 100 bp of each inserted IS2 element.
