Transparency improvement in a bilateral motion-scaling control using Kalman-filter-based disturbance observer (2014)

This paper proposes a new wideband bilateral motion-scaling control to apply in the small size robot system. The scaling Hadamard matrix is applied to reduce or magnify the force and position response of bilateral motion-scaling control. The technique to estimate the action/reaction forces of master-slave robot is designed using Kalman-filter based disturbance observer (KFDOB). Optical encoder and acceleration signals were fused to estimate contact forces occurring during an experiment. With the bilateral motion-scaling control and KFDOB, we can control the small scale master-slave robot with high precision. Comparative experiments show the KFDOB and its multi-sensor fusion to provide performance superior to that of previously disturbance observer. As seen in the experimental results, it is clear that high transparency and good perception of the environmental stiffness with the response of the master-slave robot can be achieve successfully. An additional result of FFT analysis which guarantees noise compensation is also presented.
Recent advances in fast-switching liquid-crystal mode based on uniform lying helix (ULH) (Conference Presentation) (2017)

Uniform lying Helix (ULH) is one of the most promising new LC modes for fast switching applications with alternative driving schemes such as FSC (field sequential colour). ULH operates via flexoelectric switching, unlike current commercially available liquid crystal modes that operate via dielectric switching. The realisation of mixtures with suitable flexoelectric properties requires unique materials composed of specially designed ´bi-mesogens´ and also the addition of a chiral dopant. Recent advances, updated mixture performance and other challenges such as alignment and driving for this new mode are discussed.
VALIDITY OF INTERMITTENT INFUSION HEMODIAFILTRATION (2006)

Intermittent Infusion Hemodiafiltration (IIHDF) was newly introduced to enhance solute removal from extra vascular compartment of the patient. In IIHDF, high flow infusion phase and no infusion phase was periodically changed in a HDF treatment with constant filtration flow rate. For example, 500 ml of supplementation fluid was infused to the venous line for 4 min every 20 min. Namely, 125 ml/min of infusion for first 4 min following no infusion for 16 min in a cycle under constant filtration flow rate, 35 ml/min, in case of 600 ml/hr of water removal rate for patient’s excessive water. Two chronic renal failure patients were carried out to participate an in vivo study in order to compare solute removal characteristics between IIHDF and conventional HDF (CHDF) therapies. Three IIHDF and CHDF treatments were performed for each patient as a cross over trial. Solute concentrations in patient’s plasma at pre- (Cpre) and post- (Cpost) dialysis treatment, and in the spent dialysate were determined for urea, creatinine, uric acid, inorganic phosphate, beta 2-microglobulin and albumin. As a result, there were no differences for a 4 hr reduction rate, defined as 1 – Cpost/Cpre, for all types of solute. Value for normalized removal amount, defined as M/Cpre, in IIHDF was significantly higher than that in CHDF for inorganic phosphate.
EIE: Efficient Inference Engine on Compressed Deep Neural Network (2016)

State-of-the-art deep neural networks (DNNs) have hundreds of millions of connections and are both computationally and memory intensive, making them difficult to deploy on embedded systems with limited hardware resources and power budgets. While custom hardware helps the computation, fetching weights from DRAM is two orders of magnitude more expensive than ALU operations, and dominates the required power. Previously proposed 'Deep Compression' makes it possible to fit large DNNs (AlexNet and VGGNet) fully in on-chip SRAM. This compression is achieved by pruning the redundant connections and having multiple connections share the same weight. We propose an energy efficient inference engine (EIE) that performs inference on this compressed network model and accelerates the resulting sparse matrix-vector multiplication with weight sharing. Going from DRAM to SRAM gives EIE 120x energy saving; Exploiting sparsity saves 10x; Weight sharing gives 8x; Skipping zero activations from ReLU saves another 3x. Evaluated on nine DNN benchmarks, EIE is 189x and 13x faster when compared to CPU and GPU implementations of the same DNN without compression. EIE has a processing power of 102GOPS/s working directly on a compressed network, corresponding to 3TOPS/s on an uncompressed network, and processes FC layers of AlexNet at 1.88x10^4 frames/sec with a power dissipation of only 600mW. It is 24,000x and 3,400x more energy efficient than a CPU and GPU respectively. Compared with DaDianNao, EIE has 2.9x, 19x and 3x better throughput, energy efficiency and area efficiency.
Protein deubiquitination during oocyte maturation influences sperm function during fertilisation, antipolyspermy defense and embryo development (2014)

Ubiquitination is a covalent post-translational modification of proteins by the chaperone protein ubiquitin. Upon docking to the 26S proteasome, ubiquitin is released from the substrate protein by deubiquitinating enzymes (DUBs). We hypothesised that specific inhibitors of two closely related oocyte DUBs, namely inhibitors of the ubiquitin C-terminal hydrolases (UCH) UCHL1 (L1 inhibitor) and UCHL3 (L3 inhibitor), would alter porcine oocyte maturation and influence sperm function and embryo development. Aberrant cortical granule (CG) migration and meiotic spindle defects were observed in oocytes matured with the L1 or L3 inhibitor. Embryo development was delayed or blocked in oocytes matured with the general DUB inhibitor PR-619. Aggresomes, the cellular stress-inducible aggregates of ubiquitinated proteins, formed in oocytes matured with L1 inhibitor or PR-619, a likely consequence of impaired protein turnover. Proteomic analysis identified the major vault protein (MVP) as the most prominent protein accumulated in oocytes matured with PR-619, suggesting that the inhibition of deubiquitination altered the turnover of MVP. The mitophagy/autophagy of sperm-contributed mitochondria inside the fertilised oocytes was hindered by DUB inhibitors. It is concluded that DUB inhibitors alter porcine oocyte maturation, fertilisation and preimplantation embryo development. By regulating the turnover of oocyte proteins and mono-ubiquitin regeneration, the DUBs may promote the acquisition of developmental competence during oocyte maturation.
Preparation of Stable Chitosan-Carboxymethyl Dextran Nanoparticles (2009)

Chitosan-carboxymethyl dextran nanoparticles (CHI-CMD NPs) were prepared by the formation of polyelectrolyte complex via the interaction of the positive charged amino group of chitosan and the negative charged carboxyl group of carboxymethyl dextran. Biocompatible organic reagents such as lactic acid, phosphate-buffered saline, and carbonate-bicarbonate buffer were used to make CHI-CMD NPs. The pH value of narrowly distributive CHI-CMD NP suspension was close to the physiological value of 6.8, which made it possible for it to be directly applied in an in vitro test without further additional operations. In the presence of sugars (30 mM), the colloidal stability of CHI-CMD NPs could be extended to 5 to 7 days when the particle size could be maintained within a nanometer scale, while the addition of xylose or lactose was found to most effectively extend the colloidal stability of CHI-CMD NPs to 10 days. Scanning electron microscopy, transmission electron microscopy, Fourier transform infrared spectroscopy, and X-ray diffraction analysis revealed that the structural integrity of CHI-CMD NPs was not destroyed after high steam pressure sterilization (121 degrees C, 30 min), which confirmed the autoclavable property of CHI-CMD NPs.
Growth of the Recrystallized Grain in Plastically Deformed Ice Single Crystal (1977)

Recrystallization takes place in the central bent part of ice single crystals plastically deformed by the method of three point bending. This process was observed with timelapse 16 m/m movie camera. The area of the recrystallized grain were measured from enlarged photographs of movie frames taken intermittently from films. At the steady state, the area S increased linearly with time t is expressed, as S=kt+C, where k is the areal speed of the grain growth.Since the grain grew in similar figures with the common vertical angle, the linear velocity of growing front v is derived as v=k/βr, where β is a constant, and r is the modified diameter of the grain (Fig. 8). Inverse proportionality of v to r was explained by the same relationship between the driving force P and r (eq. 11). The driving force consists of the energy of small angle grain boundaries distributed radially in the bent area and of the grain boundary energy.Then the mobility of the grain boundary M was obtained by dividing the velocity by the drivingforce P and its value ranged (3. 19. 5) × 10-10cm3.dyn.-1sec-1.
Clinical significance of normal chest radiographs among HIV‐seropositive patients with suspected tuberculosis in Uganda (2011)

Normal CXR findings were common among HIV-seropositive patients with suspected TB, especially those who were young, those with low CD4+ T cell counts and those with sputum smears that were negative for AFB. Mortality was high among those with normal CXRs. Normal CXR findings should not preclude further diagnostic evaluation in this population.
MR image quality and timing resolution of an analog SiPM based pre-clinical PET/MR insert (2012)

A pre-clinical PET insert for a clinical 3T MRI scanner has been developed to acquire PET images simultaneously with MRI data. We assessed the imaging performance of the MR scanner equipped with the PET insert by running spurious noise scans with the MR scanner and by measuring the image SNR with homogeneous standard MR phantoms of different sizes. Also the B <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">1</sub> field distribution map was measured. The noise scans on the MR scanner with the PET insert powered on showed that RF power is coupled from the PET insert into the MR acquisition system. With additional common mode blocking, the noise floor was raised by factor 1.6 when the PET insert was acquiring data compared to the case that it was switched off. MR image SNR was quantified as described in the corresponding NEMA standards publication. Without additional common mode blocking, image SNR is reduced by a factor between 1.5 and 2, depending on the size of the object. With additional common mode blocking, image SNR is reduced by a factor 1.3 only. The timing resolution of the PET scanner was also determined after twofold correction of the timestamps. Mean coincidence timing resolution is approximately 3 ns, the best observed coincidence timing resolution was approximately 2 ns and the worst observed coincidence timing resolution was approximately 6 ns.
Design of LLC resonant converter using planar magnetic component (2009)

This paper presents the design and implementation of LLC resonant converter using planar magnetic component. In the LLC resonant converter, ZVS turn-on and ZCS turn-off of MOSFETs and diode rectifiers can be achieved over the entire operating range, respectively. Therefore, the switching loss is reduced and we can operate the converter at higher switching frequency. At that frequency, planar magnetic component is a viable option. In this proposed converter, the magnetic component is integrated into advanced power conversion technique to implement a low-profile power supply for PDP application systems. An efficiency of about 96.7% was obtained.

The nature of lyophobic coating and the adsorption of organic molecules and water on modified silicas (2010)

The protective properties of lyophobic layers of various natures chemically grafted to a silica carrier were comparatively studied. The modifiers were silanes with the compositions CF3(CH2)2Si(CH3)2Cl (CF3), C8H17Si(CH3)2Cl (C8H17), and ClSi(CH3)2[OSi(CH3)2]2Cl (OMS). The differences between the surface properties of chemically modified silicas observed in adsorption, chromatographic, and IR spectroscopic measurements were shown to be related to a nonuniform electron density distribution in CF3 grafted radicals and the special features of the structure of CF3 and OMS grafted layers caused by the possibility of interaction between the terminal groups of these radicals and the surface of the carrier. Modified silicas possessed low surface energy and were superhydrophobic materials. The sample with grafted octyl groups C8H17 had the highest stability with respect to water.
4D Using Non-repeated OBS Acquisition Systems on the Njord Field (2016)

Summary Seismic monitoring has been challenging on the Njord field. The rather weak 4D responses related to production have been difficult to detect due to the noise level in the streamer 4D seismic data and due to dominant overpressure effect after injection. The streamer seismic data was replaced by Ocean Bottom Seismic (OBS) in 2010 and the first repeat was performed in 2014. The 4D noise level is expected to improve using Ocean Bottom Seismic (OBS) due to repeated receiver positions and better coverage closer to installations. However the sensor technologies and the seismic source were not repeated and we show how we accommodated for this. In addition, we will show how the lack of shallow overburden illumination through the OBS acquisition was compensated for using streamer seismic data and imaging with multiples.
New Route to Three‐Dimensional Photonic Bandgap Materials: Silicon Double Inversion of Polymer Templates (2005)

High-refractive-index, 3D photonic crystals (see Figure) are produced by silicon double inversion of a polymer woodpile template fabricated by multiphoton direct laser writing. The method incorporates silica chemical vapor deposition fine-tuning of the filling fraction of an intermediate silica inverted woodpile, and thus the ability to tailor the width of the complete photonic band gap of the silicon woodpile.
<title>Soft computing and soft communications for synchronized data</title> (1999)

In this paper a new algorithmic and hardware approach to real-time processing, computing, compression and transmission of multi-media (video, imagery, audio, sensor, telemetry, computer data) information, in the form of synchronized data, was proposed. The proposed approach, called Soft Computing and Soft Communication, leads to multi-media throughput minimization and data homogenization.

Caminibacter profundus sp. nov., a novel thermophile of Nautiliales ord. nov. within the class ‘Epsilonproteobacteria’, isolated from a deep-sea hydrothermal vent (2004)

A novel moderately thermophilic, microaerobic to anaerobic, chemolithoautotrophic bacterium, designated strain CRT, was isolated from a deep-sea hydrothermal vent site at 36 degrees N on the Mid-Atlantic Ridge. Cells were Gram-negative, non-motile rods. The organism grew at 45-65 degrees C and pH 6.5-7.4, with optimum growth at 55 degrees C and pH 6.9-7.1. The NaCl range for growth was 5-50 g l(-1) (optimum 30 g l(-1)). Strain CRT was an obligate chemolithoautotroph, growing with H2 as energy source, sulfur, nitrate or oxygen as electron acceptors and CO2 as carbon source. Hydrogen sulfide and ammonium were the respective products of sulfur and nitrate reduction. The G+C content of the genomic DNA was 32.1 mol%. Based on 16S rRNA gene sequence analysis, this organism was most closely related to Caminibacter hydrogeniphilus (94.9% similarity). On the basis of phenotypic and phylogenetic data, it is proposed that the isolate represents a novel species, Caminibacter profundus sp. nov. The type strain is CRT (=DSM 15016T=JCM 11957T). The phylogenetic data also correlate well with the significant phenotypic differences between the lineage encompassing the genera Nautilia and Caminibacter and other members of the class 'Epsilonproteobacteria'. The lineage encompassing the genera Nautilia and Caminibacter is therefore proposed as a new order, Nautiliales ord. nov., represented by a single family, Nautiliaceae fam. nov.
High field flashover strength of intrinsic gallium nitride and aluminum nitride in vacuum (1996)

The behavior of intrinsic materials (i-GaN and i-AlN) at high fields and room temperature, using small gap lateral test devices in vacuum ambient, is analyzed. Unprecedented hold-off fields of more than 375 kV/cm were obtained for intrinsic nitride layers grown on sapphire. The superior high field performance of intrinsic nitride materials indicate a great potential of nitride semiconductors for the next generation high power/high voltage/high frequency/high temperature electronic devices.
Multi-MHz Multi-kV Power Amplifier for Compact Particle Accelerators (2020)

This paper presents the design and implementation of multi-MHz multi-kV switch-mode power amplifiers suitable for accelerating ion beams in compact particle accelerators. Ion beams are sped up to mega-electron-volt levels by sending them through a series of acceleration cells driven by large high-frequency ac voltages. High frequency operation of these cells allows the length of the accelerator to be reduced. The presented power amplifiers utilize full-bridge inverters and matching networks to achieve high voltages. A comprehensive design methodology that enables high voltage gain while achieving soft switching of the inverter transistors is presented. The inductors of the matching networks are designed to achieve high quality factors, enabling large voltage gain without excessive losses. Furthermore, the matching network capacitor is realized using the parasitics of the accelerator structure, reducing the size and enhancing the reliability of the system. Two prototype power amplifiers are designed using the proposed approach, and are built and tested. The first prototype operates at 13.56 MHz and generates up to 10 kV output voltage, while the second prototype operates at 27.12 MHz and generates up to 8.3 kV output voltage. The output voltage achieved by the 27.12-MHz prototype exceeds the state-of-the-art by a factor of four.
Sustained Expression of High Levels of Human Factor IX from Human Cells Implanted within an Immunoisolation Device into Athymic Rodents (1998)

Immunoisolation of allogeneic cells within a membrane-bound device is a unique approach for gene therapy. We employed an immunoisolation device that protects allograft, but not xenograft, cells from destruction, to implant a human fibroblast line (MSU 1.2) in athymic rodents. Cells, transduced with the MFG-human factor IX retroviral vector, and expressing 0.9 microg/10(6) cells/day in vitro, were implanted in rats (four 40-microl devices, each containing 2 x 10(7) cells, two subcutaneously, two in epididymal fat) and in mice (two 20-microl devices, each containing 2 x 10(6) cells, subcutaneously). Plasma factor IX levels increased for 50 days, reaching maxima of 203 ng/ml (rat) and 597 ng/ml (mouse), and both continued at greater than 100 ng/ml for more than 140 days. A clone derived from the transduced cells, making 5 microg of factor IX/10(6) cells/day, was implanted within a device (one 20-microl device containing 2.5 x 10(6) cells), or without a device (1 x 10(7) cells implanted freely), either subcutaneously or in epididymal fat. The freely implanted cells expressed transiently, reaching more than 100 ng/ml in each site by day 4, but dropped to zero by day 20 (subcutaneous) or day 90 (epididymal fat). In devices, levels gradually increased to 100 ng/ml (subcutaneous) or 300 ng/ml (epididymal fat), remaining high for more than 100 days. These results show long-term, high-level expression of a human protein: (1) when cells are implanted within a cell transplantation device, but not when the cells are freely implanted, and (2) from a transgene driven by a viral promoter. An alloprotective device will enable the use of cloned cell lines that can be subjected to stringent quality control assessment that is impossible to achieve with autologous approaches.
