Cell Surface Glycoproteins of Hepatocytes and Hepatoma Cells Identified by Monoclonal Antibodies (1986)

Eight hybridoma cell lines secreting monoclonal antibodies (MABs) directed to cell surface components of rat hepatocytes were isolated. The antigens of seven MABs were identified as glycosylated plasma membrane proteins. The presence of these glycoproteins on normal hepatocytes and hepatocellular carcinoma cells was analyzed. A semi-quantitative enzyme-linked immunosorbent assay revealed that only two MABs (Be 8.7, Ne 11.3) recognized proteins which were expressed not only in normal liver but also in chemically induced transplantable Morris hepatomas and hepatoma-derived cell lines. The expression of six antigens was found to be sensitive to transformation. The domain specificity of the MABs was determined by indirect immunofluorescence on sections of liver tissue containing neoplastic nodules. Three MABs (Be 8.4, Ne 11.1, Ne 11.3) specifically bound to the sinusoidal domain and two MABs (Be 9.2, De 13.4) to the bile canalicular domain. These five antigens were transformation-sensitive except for the glycoprotein recognized by the MAB Ne 11.3. Three MABs (Be 8.7, Be 9.1, De 13.2) also showed intracellular immunofluorescence. Two of the antigens (Be 9.1, De 13.2) were not present in hepatomas. The relative molar masses (Mr) of the glycoproteins were determined after protein immunoblotting and immunoprecipitation. Four MABs (Be 8.7, Be 9.1, Be 9.2, De 13.4) recognized antigens with a Mr of 110 000 but did not mutually cross-react. The antigen recognized by MAB De 13.4 was identified as the ectoenzyme dipeptidyl peptidase IV (EC 3.4.14.-).
High resolution tracking of non-rigid 3D motion of densely sampled data using harmonic maps (2005)

We present a novel fully automatic method for high resolution, nonrigid dense 3D point tracking. High quality dense point clouds of nonrigid geometry moving at video speeds are acquired using a phase-shifting structured light ranging technique. To use such data for the temporal study of subtle motions such as those seen in facial expressions, an efficient nonrigid 3D motion tracking algorithm is needed to establish inter-frame correspondences. The novelty of this paper is the development of an algorithmic framework for 3D tracking that unifies tracking of intensity and geometric features, using harmonic maps with added feature correspondence constraints. While the previous uses of harmonic maps provided only global alignment, the proposed introduction of interior feature constraints guarantees that nonrigid deformations are accurately tracked as well. The harmonic map between two topological disks is a diffeomorphism with minimal stretching energy and bounded angle distortion. The map is stable, insensitive to resolution changes and is robust to noise. Due to the strong implicit and explicit smoothness constraints imposed by the algorithm and the high-resolution data, the resulting registration/deformation field is smooth, continuous and gives dense one-to-one inter-frame correspondences. Our method is validated through a series of experiments demonstrating its accuracy and efficiency.
Cryoelectric hybrid system for very large random access memory (1968)

The recent introduction of structured cells characterized by no cell-to-cell interaction, adequate sense signal, and array tolerance under repetitive worse-case disturb evaluation and coincident current operation, has made possible new systems approaches. A coincident current "hybrid" (word-bit) system utilizing room temperature decoders and structured loop cell arrays was designed to satisfy the criteria pertinent to a very large random access cryoelectric memory. Besides offering the advantage of an early realization of a cryoelectric memory, compared to previous systems advanced, several other benefits are realized: 1) low electronics cost, especially in large systems sizes, 2) low heat load, and 3) potential plane yield improvement through redundancy techniques. Although a disadvantage is the large number of interconnections, analysis shows that the overall memory cost can be minimized through proper substrate design. The technology required by the hybrid system embodies present art, and very large random access cryoelectric memories employing hybrid organization and loop cell arrays appear to be feasible.
Nutrition Discussion Forum (1997)

Dr Bates makes five specific criticisms of my recent paper (Hemilä, 1997a) to which I shall respond separately ... The possibility of publication bias and various technical shortcomings in the published studies should not discourage us from planning and carrying out carefully designed trials which address these questions more explicitly. The findings of such trials would provide a more solid scientific basis for further discussions about the appropriate intake levels.
A 3-D Modeling System Using Hands Gesture (2011)

We present a 3-D modeling system that uses hand gestures for quickly and easily designing freeform models. The user illustrates a 3-D freeform in the air and the system automatically constructs plausible 3-D polygonal surfaces. A stereo camera captures the users' hands. We obtain a set of a vast number of points in a 3-D space that presents the freeform. The points are organized using voxel representation to remove redundancy of the points. The organized points are rendered using the Marching cubes method. Our informal study on first-time users showed that a first-time user typically masters the operations within a minute and can construct interesting 3-D models within seconds.
Monte Carlo treatment of resonance-radiation imprisonment in fluorescent lamps (1985)

The imprisonment of the 2537-A\r{} resonance radiation from mercury in the mercury-argon discharge of fluorescent lamps is treated by a Monte Carlo method. The effects of emission and absorption linewidths, hyperfine splitting, isotopic composition, collisional transfers of excitation, and quenching are explicitly incorporated in the calculations. The calculated spectra of emitted radiation are in good agreement with measured spectra for several combinations of lamp temperature and mercury composition. Also in agreement with experiments, the addition of $_{{\mathrm{}}^{1}{\mathrm{}}_{80}^{96}}\mathrm{Hg}$ to natural mercury is found to increase lamp efficiency. The method is useful for a number of problems in radiation transfer.
Formant Centralization Ratio: A Proposal for a New Acoustic Measure of Dysarthric Speech (2009)

Albeit preliminary, the present findings indicate that the FCR is a sensitive, valid, and reliable acoustic metric for distinguishing dysarthric from unimpaired speech and for monitoring treatment effects, probably because of reduced sensitivity to interspeaker variability and enhanced sensitivity to vowel centralization.
Analysis of the V genes coding for a monospecific human antibody to myosin and functional expression of single chain Fv fragments (1999)

A monospecific human IgM monoclonal antibody (mAb), reactive with myosin from human heart, has been obtained by EBV transformation. This mAb may have a diagnostic potential in the imaging of myocardial necrosis. However, owing to the fact that the molecular mass of an IgM is 900 kDa, a poor diffusion and a slow penetration inside necrotic myocytes could reduce its capacity for scintigraphic detection. In order to alleviate these problems, we constructed the scFv by cloning the VH and VL domains into the pHOG21 vector. Analysis of the V genes proved an unmutated configuration showing that the immortalized B cell issued from the primary IgM repertoire. The expression product in Escherichia coli was a 35 kDa scFv fragment with the antigen-binding specificity of the parental mAb.
Conservative management of unilateral acoustic neuromas. (2000)

Watchful expectation can be regarded as a safe approach for selected cases of acoustic neuromas. Surgery or irradiation is indicated in patients with proven growth of their tumors.
3.3 V write-voltage Ir/Ca<sub>0.2</sub>Sr<sub>0.8</sub>Bi<sub>2</sub>Ta<sub>2</sub>O<sub>9</sub>/HfO<sub>2</sub>/Si ferroelectric-gate field-effect transistors with 10<sup>9</sup>endurance and good retention (2017)

Ir/Ca0.2Sr0.8Bi2Ta2O9 (CSBT)/HfO2/Si ferroelectric-gate field-effect transistors (FeFETs), which were appropriate for low-voltage 3.3 V operations, were developed. The key to the success was the use of N2-dominant gas mixed with a small amount of O2 in a gas flow during the annealing of the FeFETs at 780 °C for CSBT polycrystallization. The Ir gate was newly developed for overcoming the problem of Pt peeling off from the CSBT surface during the novel annealing process. For maximizing the memory windows of the FeFETs, the optimum flow rate of O2 mixed with 1000-sccm-fixed N2 was found to be as low as 0.5 sccm. The novel annealing process suppressed the SiO2 interfacial layer growth to 2.6 nm thickness. The annealing also improved CSBT ferroelectricity. A 109 cycle endurance and a 105 s retention were demonstrated by 3.3 V writing of the FeFETs.
Use of adaptive optics for improved multiphoton imaging (2004)

We report on the integration of active optical elements in a multiphoton microscope to improve the resolution and overall image quality when imaging deeply into biological samples. Optical models were generated of sample systems and these have been compared with the performance of the complete imaging system. The active elements used were commercially available flexible membrane mirrors controlled by custom, home written, software. Significant improvements in image quality have been demonstrated using a range of optimisation routines based on the analysis of the images produced by the system, rather than with a wavefront sensor. A three-fold increase in the resolution 100μm into the sample was achieved.

Specificity of staphylococcal phage and SaPI DNA packaging as revealed by integrase and terminase mutations (2009)

SaPI1 and SaPIbov1 are chromosomal pathogenicity islands in Staphylococcus aureus that carry tst and other superantigen genes. They are induced to excise and replicate by certain phages, are efficiently encapsidated in SaPI-specific small particles composed of phage virion proteins and are transferred at very high frequencies. In this study, we have analysed three SaPI genes that are important for the phage-SaPI interaction, int (integrase) terS (phage terminase small subunit homologue) and pif (phage interference function). SaPI1 int is required for SaPI excision, replication and packaging in a donor strain, and is required for integration in a recipient. A SaPI1 int mutant, following phage induction, produces small SaPI-specific capsids which are filled with partial phage genomes. SaPIbov1 DNA is efficiently packaged into full-sized phage heads as well as into SaPI-specific small ones, whereas SaPI1 DNA is found almost exclusively in the small capsids. TerS, however, determines DNA packaging specificity but not the choice of large versus small capsids. This choice is influenced by SaPIbov1 gene 12, which prevents phage DNA packaging into small capsids, and which is also primarily responsible for interference by SaPIbov1 with phage reproduction.
On Gain-Bandwidth Product for Distributed Amplifiers (Short Paper) (1986)

Contours of constant gain-bandwidth product as a function of the gate and drain attenuation factors are presented. Design tradeoffs are established. It is shown that only one design achieves maximum gain-bandwidth, although many possible choices approach this maximum. The curves also lead to the specification of active device parameters when circuit requirements are known.
The effect of record flying height on trackedge noise in thin film media (1995)

The effects of record spacing on trackedge noise are studied for CoCrTa and CoCrPt-CoCrTa media. Variations in record spacing (separation from magnetic media to write head pole tips) are accurately achieved by using an identical set of disks for each type of media, with different overcoat thicknesses. Trackedge noise is characterized using track profiles of the media noise. An integrated spectral technique is used to measure media noise, and the effects of the different playback spacings (separation from magnetic media to read head pole tips or read element) are removed by dividing the spectral playback loss factor from the media noise spectra. Track profiles were performed at three linear record densities for each record spacing. For both media, on-track noise and trackedge noise are found to decrease with reduced record spacing, and the amount of decrease is found to be record density dependent. However, the trackedge noise did not decrease as dramatically as the on-track noise with reduced record spacing.
A novel FPGA based off-line control strategy for SRM integrated vehicle propulsion system (2009)

Much attention has been recently drawn towards switched reluctance machine (SRM) based vehicle propulsion systems. This is especially due to the excellent extended speed features of SRMs for electric/hybrid electric vehicle propulsion applications. However, the inherently large torque ripple and highly nonlinear characteristics of SRMs present significant challenges from the controller design standpoint. Appropriate design of a control smart scheme is critical, in order to enhance overall performance. This paper proposes a novel field programmable gate array (FPGA) based off-line control strategy, to minimize the overall torque ripple and deal with the nonlinearities. However, due to its ¿off-line¿ feature, the precise inductance model of SRM ought to be determined. For this purpose, this work also involves usage of a suitable current saturation method. Suitable simulation test results are discussed and in-depth analyses, inferences, as well as future research directions are presented.
Cholecystokinin Excites Interneurons in Rat Basolateral Amygdala (2009)

The amygdala formation is implicated in generation of emotional states such as anxiety and fear. Many substances that modulate neuronal activity in the amygdala alter anxiety. Cholecystokinin (CCK) is an endogenous neuropeptide that induces anxiety states in behavioral studies in both animals and humans. Using a brain slice preparation, we found that application of CCK increases inhibitory synaptic transmission measured in projection neurons of the basolateral amygdala. To determine the source of the increased inhibition we examined the direct effect of CCK on local interneurons in this region. CCK most strongly depolarized fast-spiking interneurons. Burst-firing and regular-firing interneurons were also depolarized, although to a lesser degree. However, another distinct group of interneurons was unaffected by CCK. These effects were mediated by the CCKB receptor subtype. The excitatory effect of CCK appeared to be mediated by both a nonselective cation and a K+ current.
Anterior cruciate ligament reconstruction using one-third of the patellar ligament, augmented by extra-articular tendon transfers. (1982)

Eighty patients with persistent clinical and functional instability of the knee due to anterior cruciate ligament insufficiency underwent the operation reported, in which one-third of the patellar ligament substitutes for the cruciate ligament and extraarticular tendon transfers, medial and lateral, augment the substitution. The patients were followed for a minimum of two years, and fifty returned for personal evaluation. The average follow-up was thirty-three months, with a range of two to five years. There were thirty-five male and fifteen female patients. The average age was twenty-three years. The average interval from initial injury to the index operation was two years. Meniscal tears and articular changes were noted in most of the patients. Forty-three (86 per cent) of the fifty patients had at least one torn meniscus, twenty-seven patients (54 per cent) had significant degenerative articular changes, and fourteen (28 per cent) had patellar articular changes. In the procedure described, eccentric placement of the tibial and femoral tunnels for more accurate placement of the patellar ligament substitute is essential. The over-all results were graded as excellent in thirty knees, good in seventeen, fair in one, and a failure in two. One knee that was classified as a failure showed excellent stability, but the patient had significant pain from chondromalacia of the patella, while significant pain and hyperesthesia from a neuroma was the reason for failure in the second patient.
Chitosanase activity of the enzyme previously reported as β-1,3-1,4-glucanase from<i>Bacillus circulans</i>WL-12 (1998)

Chitosanases 33 kDa and 40 kDa in size were detected in the culture supernatant of Bacillus circulans WL-12. One of the two chitosanases, chitosanse 40 (40-kDa chitosanase) has been shown to be identical to the enzyme which has been reported previously as a beta-1,3-1,4-glucanase by Bueno et al. The enzyme has been classified into family 8 glycosyl hydrolases together with the enzymes formally known as cellulase family D. This enzyme named chitosanase 40/beta-1,3-1,4-glucanase hydrolyzed both chitosan and beta-1,3-1,4-glucan with similar efficiency. However, the production of the enzyme was induced with chitosan but not by beta-1,3-1,4-glucan. Therefore, it seems possible that the major substrate of this enzyme is chitosan rather than beta-1,3-1,4-glucan. Analysis of degradation products generated from partially N-acetylated chitosan showed that chitosanase 40/beta-1,3-1,4-glucanse hydrolyzes GlcN-GlcN and GlcN-GlcNAc linkages but not GlcNAc-GlcNAc nor GlcNAc-GlcN. The specificity for hydrolyzing linkages of this enzyme is similar to that of the chitosanase from S. griseus HUT6037.
Near-Infrared Photoluminescence and Electroluminescence of Neodymium(III), Erbium(III), and Ytterbium(III) Complexes (2001)

Tris(dibenzoylmethanato)(monobathophenanthroline)lanthanide(III) complex [Ln(DBM) 3 bath (Ln: Nd, Er and Yb)] both in solutions and thin films at room temperature showed narrow band photoluminescence (PL) due to the f – f transitions in the near-IR region: 890, 1070 and 1350 nm for Nd(III), 980 and 1540 nm for Er(III), and 985 nm for Yb(III). The PL efficiencies in solution were determined [φ PL =3.3×10 -3 for Nd(III), 7.0×10 -5 for Er(III), and 1.4×10 -2 for Yb(III)]. Organic electroluminescent (EL) devices having the structure of glass substrate/indium-tin oxide/ N , N ′ -diphenyl- N , N ′ -di( m -tolyl)benzidine/Ln(DBM) 3 bath(Ln: Nd, Er and Yb)/bathocuproine/Mg:Ag/Ag were fabricated, giving the EL bands around 900–1600 nm at room temperature. The external near-IR EL efficiencies at low current density were estimated by comparing with that of the Eu(III) device having the same structure. The saturation of near-IR EL intensity observed at the high current density suggested that the near-IR EL should suffer the T–T annihilation.
Tapping mode imaging with an interfacial force microscope (1997)

In their present embodiment, sensors used in interfacial force microscopy do not have the necessary mechanical bandwidth to be employed as free-running tapping mode devices. We describe an extremely stable method of obtaining tapping mode images using feedback on the sensor. Our method is immune to small dc drifts in the force signal, and the prospect of diminishing the risk of damaging fragile samples is realized. The feasibility of the technique is demonstrated by our imaging work on a Kevlar fiber-epoxy composite. We also present a model which accounts for the frequency dependence of the sensor in air when operating under closed loop control. A simplified force modulation model is investigated to explore the effect of contact on the closed loop response of the sensor.
Abiotic Stress Generates ROS That Signal Expression of Anionic Glutamate Dehydrogenases to Form Glutamate for Proline Synthesis in Tobacco and Grapevine (2006)

Glutamate dehydrogenase (GDH) may be a stress-responsive enzyme, as GDH exhibits considerable thermal stability, and de novo synthesis of the alpha-GDH subunit is induced by exogenous ammonium and senescence. NaCl treatment induces reactive oxygen species (ROS), intracellular ammonia, expression of tobacco (Nicotiana tabacum cv Xanthi) gdh-NAD;A1 encoding the alpha-subunit of GDH, increase in immunoreactive alpha-polypeptide, assembly of the anionic isoenzymes, and in vitro GDH aminating activity in tissues from hypergeous plant organs. In vivo aminating GDH activity was confirmed by gas chromatorgraphy-mass spectrometry monitoring of (15)N-Glu, (15)N-Gln, and (15)N-Pro in the presence of methionine sulfoximine and amino oxyacetic acid, inhibitors of Gln synthetase and transaminases, respectively. Along with upregulation of alpha-GDH by NaCl, isocitrate dehydrogenase genes, which provide 2-oxoglutarate, are also induced. Treatment with menadione also elicits a severalfold increase in ROS and immunoreactive alpha-polypeptide and GDH activity. This suggests that ROS participate in the signaling pathway for GDH expression and protease activation, which contribute to intracellular hyperammonia. Ammonium ions also mimic the effects of salinity in induction of gdh-NAD;A1 expression. These results, confirmed in tobacco and grape (Vitis vinifera cv Sultanina) tissues, support the hypothesis that the salinity-generated ROS signal induces alpha-GDH subunit expression, and the anionic iso-GDHs assimilate ammonia, acting as antistress enzymes in ammonia detoxification and production of Glu for Pro synthesis.
