Humanoid robot and its application possibility (2003)

Research on humanoid robots has become a very active area. The Japanese Ministry of Economy, Trade and Industry (METI) has run the Humanoid Robotics Project since 1998 with Prof. Hirochika Inoue, the University of Tokyo, as the leader and the Manufacturing Science and Technology Center (MSTC) as the project secretary. It was carried out with the participation of Intelligent Systems Institute/AIST, University of Tokyo and several companies. There were two major missions of the project. The first is application research, which entails finding a promising application of humanoid robots that can initialize mass production in the humanoid robot industry. In application research, five applications of humanoid robots, i.e. maintenance tasks of industrial plants, security services of home and office, human care, teleoperations of construction machines, and cooperative work in the open air were explored. The second is platform research, which entails developing a practical humanoid experimental platform with an open software structure that can be used by various researchers and engineers aiming to develop new humanoid functions and/or new practical applications. In order to use the experimental platform for application research, platform research began earlier than application research. In the first two years of the project period, the research efforts were concentrated on platform research and two types of humanoid platform, HRP-1 and HRP-1S based on Honda P3 were developed together with a humanoid simulator and a remote control cockpit. In the following three years, by using the two platforms, application research was carried out and the third humanoid platform, HRP-2, was developed.
Diffracting trees (preliminary version) (1994)

Shared counters are among the most basic coordination structures in multiprocessor computation, with applications ranging from barrier synchronization to dynamic load balancing. Introduced in this paper are diffracting trees, novel distributed-parallel data structures for shared counting. Diffracting trees combine a randomized coordination method together with a combinatorial data structure, to yield a logarithmic depth counter that improves on the log2 depth of counting networks, and overcomes the resiliency drawbacks of combining trees. Empirical evidence collected on a simulated distributed shared-memory multiprocessor shows that diffracting trees substantially outperform both combining trees and counting networks, currently the most effective known methods for shared counting. Not only do diffracting trees have higher throughput and lower latency, but unlike any known technique, their latency remains almost constant as the number of processors increases.
Testing Cement Static Tensile Behavior Under Downhole Conditions (2005)

Abstract Today's analytical models can calculate stresses imposed upon the annular cement sheaths of wells, and it has become apparent that induced stresses can often be tensile in nature. These models often predict the cement failing in tension as well. This understanding has caused the industry to step beyond API tests that only recognize methods for testing cement under compressional loads. Instead, the determination of cement tensile mechanical parameters should be considered as important as cement compressive strength. Unfortunately, with no API guidelines, most oilfield cement tensile behavior testing typically uses ASTM construction concrete test methodology. With oilfield cements, most ASTM tests suffer from various shortcomings. These can be traced to the fact that they are designed primarily to test construction cements that are not usually placed more than a few meters underground. These tests do not incorporate procedures to replicate the curing of the cement in downhole environments, and do not conduct the actual static tensile testing under conditions similar to those occurring in oil and gas wells. When oilfield cements are prepared and cured using API procedure in HTHP curing chambers, they must still be subjected to significant induced stresses as cooling and de-pressurization back to ambient conditions occur before they can be subjected to ASTM tests. Samples prepared and tested in such a manner may undergo sufficiently induced stress to exhibit physical signs of initial mechanical failure, prior to even being placed in ASTM testing fixtures. To produce cement tensile behavior data that is more reflective of actual downhole performance, the authors developed an automated, microprocessor controlled testing device that cures and mechanically tests the cement under simulated downhole conditions. Once slurry is placed in the testing device, and the temperature and pressure is ramped up to simulate downhole curing conditions, the samples never see ambient conditions again until the conclusion of testing. The microprocessor controls and automated data acquisition unit also allow for the determination of tensile stress-strain relationships, prior to testing the sample to ultimate (mechanical) failure in tension. In this work, the authors present detailed descriptions of the operational capabilities of the new testing device, along with data developed with the device. Using the tensile data developed under more realistic downhole conditions, induced stress models can now generate even more accurate predictions about fit-for-purpose cement designs for wells of all depths and applications.
An Automatic Control System For Oxygen Therapy Of Newborn Infants (2005)

A microcomputer-based control system is developed to adjust the concentration of inspired oxygen of neonates under incubator treatment. The proposed method uses a proportional, integral, derivative (PID) controller and the feedback of arterial oxygen saturation to control the arterial partial pressure of oxygen of newborn infants. The concentration of oxygen in the inspired gas of the neonate is adjusted to provide for sufficient oxygenation of the blood and is kept low enough to prevent the damaging effects of oxygen toxicity. The performance of the control system is investigated by computer simulation, and some of the results of the study are presented.
Magnetostriction of Pd-Fe alloys (1984)

The linear magnetostriction λs of polycrystalline Pd1−xFex alloys has been measured as a function of alloy composition, at temperatures of 300, 77, and 4.2 K. The effect on λs of atomic ordering of Pd3Fe and PdFe type has been investigated. The value of λs is positive for x&gt;0.21, but changes sign three times in the composition range x&lt;0.21. This composition dependence can be understood semiquantitatively in terms of the simple split-band model, where iron and palladium each have their own d band, distinct on the energy scale. Contributions to λs from electrons of both spin directions have been included. Best fit between theory and data is obtained for a value of the deformation potential of d electrons equal to −0.6 eV. The anomalous Hall effect and the g factor of Pd-Fe are also discussed in the light of the split-band model.
A frequency domain blind signal separation method based on decorrelation (2002)

This paper addresses the issue of separating multiple speakers from mixtures of these that are obtained using multiple microphones in a room. An adaptive blind signal separation algorithm, which is entirely based on second-order statistics, is derived. One of the advantages of this algorithm is that no parameters need to be tuned. Moreover, an extension of the algorithm that can simultaneously deal with blind signal separation and echo cancellation is derived. Experiments with real recordings have been carried out, showing the effectiveness of the algorithm for real-world signals.
Solid-dielectric compound parabolic concentrators: on their use with photovoltaic devices (1976)

Prototype solid dielectric compound parabolic concentrators have been made and tested. By means of the geometry and refractive properties of a transparent solid they provide a technique for increasing the power output of silicon solar cells exposed to the sun by an amount nearly equal to the increase in effective collecting area. The response is uniform over a large angle which eliminates the necessity of diurnal tracking of the sun. The technique can be applied to the construction of thin panels and has the potential for significantly reducing, their cost per unit area.
Amplitude Bounds and Quantization Schemes in Walsh-Fourier Domain (1971)

Discrete Walsh-Fourier transform (WET) have found increasing use in the area of digital signal processing and transmissicon. Assuming that the signal is amplitude-bounded, bounds on the WFT domain sample amplitudes are obtained. From an appropriately chosen group of sample amplitudes in the WET domain, corresponding set of mutually exclusive and exhaustive subsums in the signal damain can be obtained. From the knowledge of these subsums, amplitude bounds on the remaining WET domain samples can be obtained. The group of sample amplitudes in the WFT domain may be recursively chosen. This results into the partitioning of WET domain in various sets such that all the samples of a particular set have the same amplitude bounds. Two such recursive procedures are worked out. Set-dependent quantization transfer characteristics, restricteci within the dynamic amplitude range appropriate to individual sets, are proposed. Effect of both the set-dependent WFT damain quantization schemes on the reconstructed signal is analyzed. Efficient computational algorithms are developed. Appropriate signal characteristics for both the schemes are pointed out.
Network Modeling of TGFβ Signaling in Hepatocellular Carcinoma Epithelial-to-Mesenchymal Transition Reveals Joint Sonic Hedgehog and Wnt Pathway Activation (2014)

Epithelial-to-mesenchymal transition (EMT) is a developmental process hijacked by cancer cells to leave the primary tumor site, invade surrounding tissue, and establish distant metastases. A hallmark of EMT is the loss of E-cadherin expression, and one major signal for the induction of EMT is TGFβ, which is dysregulated in up to 40% of hepatocellular carcinoma (HCC). We have constructed an EMT network of 70 nodes and 135 edges by integrating the signaling pathways involved in developmental EMT and known dysregulations in invasive HCC. We then used discrete dynamic modeling to understand the dynamics of the EMT network driven by TGFβ. Our network model recapitulates known dysregulations during the induction of EMT and predicts the activation of the Wnt and Sonic hedgehog (SHH) signaling pathways during this process. We show, across multiple murine (P2E and P2M) and human HCC cell lines (Huh7, PLC/PRF/5, HLE, and HLF), that the TGFβ signaling axis is a conserved driver of mesenchymal phenotype HCC and confirm that Wnt and SHH signaling are induced in these cell lines. Furthermore, we identify by network analysis eight regulatory feedback motifs that stabilize the EMT process and show that these motifs involve cross-talk among multiple major pathways. Our model will be useful in identifying potential therapeutic targets for the suppression of EMT, invasion, and metastasis in HCC.
Installation and testing of a focusing mirror at beamline X28C for high flux x-ray radiolysis of biological macromolecules (2008)

The NSLS X28C white-light beamline has been upgraded with a focusing mirror in order to provide increased x-ray density and a wide selection of beam shapes at the sample position. The cylindrical single crystal silicon mirror uses an Indalloy 51 liquid support bath as both a mechanism for heat transfer and a buoyant support to counter the effects of gravity and correct for minor parabolic slope errors. Calorimetric measurements were performed to verify that the calculated more than 200-fold increase in flux density is delivered by the mirror at the smallest beam spot. The properties of the focused beam relevant to radiolytic footprinting, namely, the physical dimensions of the beam, the effective hydroxyl radical dose delivered to the sample, and sample heating upon irradiation, have been studied at several mirror angles.
Kinetics of nonself surface adhesion and phagocytic response of hemocytes of Scylla serrata exposed to sodium arsenite (2008)

Edible mud crab Scylla serrata (Crustacea : Decapoda) is an economically important species. Hemocytes - the blood cells of the species perform diverse immunological functions including nonself recognition and phagocytosis of nonself particles. Kinetics of nonself surface (glass) adhesion of hemocytes was determined under the exposure of 1, 2, 3 ppm of sodium arsenite in diverse span of exposure i.e. 24, 48, 72 and 96 hours in controlled laboratory condition. Shifts in kinetics of adhesion were recorded against all the concentration screened. However, the patterns of shift were not uniform. Arsenic induced shift in surface adhesion of hemocytes indicated a state of immunological stress in the species. Phagocytosis of nonself particulates is considered as a classical immunological response in crab. We have examined phagocytosis of yeast ( Saccharomyces cerevisiae ) by hemocytes of animal exposed to 1, 2 and 3 ppm of sodium arsenite for 24, 48, 72 and 96 hours in vitro . Alteration in phagocytic response and adhesion of hemocytes is suggestive of cellular stress which may lead to decline in population of S. serrata in arsenic affected districts of West Bengal.
Semi-Static Dataflow. (1988)

In this paper we present a new dataflow execution model called semi-static dataflow. This model incorporates aspects of conventional static and dynamic dataflow architectures. Programs are partitioned into a collection of dataflow graphs. The execution of each of these graphs is the responsibility of a low-level process called a context. The static
Characterization of the promoter region of the membrane cofactor protein (CD46) gene of the human complement system and comparison to a membrane cofactor protein-like genetic element. (1993)

Membrane cofactor protein (MCP; CD46) is a widely expressed C regulatory protein that inhibits C activation on self-tissue. MCP binds C3b and C4b deposited on autologous cells and then serves as a cofactor for their inactivation by limited proteolytic cleavage. To characterize the DNA sequence elements responsible for controlling MCP expression, the 5' flanking region of the human MCP gene was cloned. Sequencing of 1350 nucleotides upstream from the ATG codon revealed a GC-rich region in the initial 500 nucleotides that is especially rich in the CpG dinucleotide. A CAAT box in reverse orientation, surrounded by four putative SP1 binding sites but lacking a typical TATA element, was within the first 200 nucleotides of this GC-rich region. The major transcriptional initiation site for HeLa cells, determined by primer extension and S1 nuclease protection analyses, was located 105 nucleotides from the translational start site. This overall orientation of the promoter region is characteristic of "housekeeping" genes. The MCP promoter region was further examined in HEp-2 cells by the chloramphenicol acetyltransferase (CAT) reporter gene assay, using various constructs derived from the 5' region of the MCP gene. The MCP promoter activity was confined to the GC-rich region from -624 to +96 (start site of transcription being +1). Inclusion of an AT-rich sequence from -624 to -1204 resulted in a 42% reduction in CAT activity suggesting that an inhibitor is present among the AT-rich sequences. The 5' flanking region of a highly homologous partial duplication of the MCP gene was also cloned and sequenced, and various constructs were assessed in the CAT reporter system. Many of the functionally relevant sequences seen in MCP are also found in the MCP-like 5' UT region, which is 85% homologous to MCP. The most striking difference was a 224 nucleotide deletion that was upstream from the corresponding MCP region harboring most of the promoter activity. Although expression of an MCP-like protein has not been reported, the MCP-like promoter region produced promoter activity comparable with that of MCP. These results serve as a basis for subsequent analyses of the expression of MCP in various cells and tissues and for understanding the mechanism of its modulation in inflammatory conditions. Also, through a comparison of the 5' region of MCP with other genes in the regulators of C activation gene cluster (at 1 q32), we propose a model for the evolution of the promoters in this tight linkage group.(ABSTRACT TRUNCATED AT 400 WORDS)
Comorbidity between post-traumatic stress disorder and major depressive disorder: alternative explanations and treatment considerations (2015)

Approximately half of people with post-traumatic stress disorder (PTSD) also suffer from Major Depressive Disorder (MDD). The current paper examines evidence for two explanations of this comorbidity. First, that the comorbidity reflects overlapping symptoms in the two disorders. Second, that the co-occurrence of PTSD and MDD is not an artifact, but represents a trauma-related phenotype, possibly a subtype of PTSD. Support for the latter explanation is inferred from literature that examines risk and biological correlates of PTSD and MDD, including molecular processes. Treatment implications of the comorbidity are considered.
Cellular arrays for the parallel implementation of binary error-correcting codes (1969)

A cellular array is a logical network of identical or almost identical cells, each of which contains a small amount of logic and storage, and, except for a few buses to the edge of the array, is connected only to its immediate neighbors. The cellular approach offers special advantages for realization by the forthcoming large-scale-integrated (LSI) technology. Such arrays are shown to be applicable for the encoding and decoding of binary error-correcting codes, and also for identifying the possibilities of tradeoffs between decoding time and equipment complexity. Arrays are presented for the decoding of single errors, burst errors, and erasures; the decoding of erasures is accomplished by the equation-solution approach, and it is shown for several code families that the Gauss elimination procedure is not required.

Isoleucyl-tRNA synthetase from baker's yeast and from Escherichia coli MRE 600. Discrimination of 20 amino acids in aminoacylation of tRNAIle-C-C-A(3'NH2) (1987)

For discrimination between isoleucine and the other 19 naturally occurring amino acids by isoleucyl-tRNA synthetases from baker's yeast and from Escherichia coli MRE 600 discrimination factors have been determined from kcat and Km values in aminoacylation of the modified tRNA(Ile)-C-C-A(3'NH2). Discrimination factors D1 are products of an initial discrimination factor and a proof-reading factor: D1 = I1.II1. From discrimination factors and AMP formation stoichiometry factors I1 and II1 were calculated. D1 values obtained with the enzyme from E. coli are generally higher than those observed with the yeast enzyme, in some cases up to ten times. With both enzymes low D1 values are found for cysteine, valine, and tryptophan (20-200), the highest values for glycine, alanine, and serine (600-4000). I1 values calculated for the E. coli enzyme are slightly higher (4-145) than the factors observed with the yeast enzyme (1-85), proof-reading factors II1 of the E. coli enzyme are scattering about a mean value about 70, those of the yeast enzyme about a mean value about 50. Initial discrimination factors I1 are directly related to hydrophobic interaction forces between the substrates and the enzymes. Plots of Gibbs free energy differences calculated from these factors are linearly related to the accessible surface areas of the amino acids. A hypothetical model of the binding site can be given in which selection of amino acids is achieved by hydrophobic forces and removal of steric hindrance.
Development of a software procedure for Curved Layered Fused Deposition Modelling (CLFDM) (2009)

Fused Deposition Modelling (FDM) is one of the most widely used Rapid Prototyping processes that uses the technique of depositing a semi-solid material in layers to build up a part and finds application in a variety of situations, be it making a mould for the rapid production of an industrial tool or the production of models for preoperative planning of complex cranial reconstructive surgery. When it comes to directly producing the end products, the process is still in its infancy, using inferior materials and flat layer deposition, bringing forth shortcomings such as poor surface quality, low strength for curved parts, and undesirably higher number of layers. Some of these shortcomings can be overcome if material deposition is modelled in curved layers as against the traditional flat-layer slicing and deposition. While the stair case effect can be significantly minimized, mechanical properties of the parts will also be enhanced due to continuity in fibres and the elimination of the inherent weakness between laminations. However, this being a fairly new idea, there are no existing facilities for practically implementing and experimentally testing this concept of Curved Layered Fused Deposition Modeling (CLFDM). The current research is to develop both hardware and software systems to build a working FDM system and implement CLFDM. The project involves the construction of an FDM system and then development of mathematical models for curved slicing. The numerical data generated from curved slicing algorithms is integrated with the hardware system for the practical implementation of CLFDM. Efficient curved slicing algorithms are developed and successfully used on the FDM system built for the practical implementation of CLFDM. Several case studies involving geometrical complications of increasing complexities have been successfully modelled and physically produced using CLFDM.
Phospholipid Profiles of Neoplastic Human Breast Tissues (1990)

Abstract Membrane phospholipids from malignant, benign and non-involved human breast tissues were extracted by chloroform-methanol (2:l) and analyzed by 31P MR spectroscopy at 202.4 MHz. Fourteen phospholipids were identified as constituents of the profiles obtained among the 52 specimens of the three groups: PC, PC plas LPC, LPC plas, PE, PE plas, LPE, PS, SPH, PI, CL, PG, PA and one uncharacterized resonance at 0.13 6. The relative P-lipid profile mole percentages of phosphorus and indices representing sums and ratios of individual or grouped P-lipids were computed and analyzed by one-way analysis of variance and were compared as simple and complex statistical contrasts. The analysis permitted differentiation among the three groups with the most poignant simple contrast being the relative absence of PA in normal tissues, followed by the significant mean mole percentage differences in PC plas between noninvolved (3.09 ± 0.41) and malignant (4.49 ± 0.23) tissues and between these same tissues in the value, of the PC plas/PC index with mean values of 0.07 ± 0.01 and 0.10 ± 0.006, respectively. Significant complex contrasts were seen between the combined neoplastic tissues and noninvolved tissue in PE plas, LPC plas, PC plas and the (PA/Total Phosphatides-PA) index. Differences were also seen between malignant and non-malignant tissues in LPC, the LPC/PC, LPE/PE and PC plas/PC indices. Differentiation among histologically classified human breast tissues is possible with phospholipid profile analysis and metabolic insight.
