Recognition of Subsurface Defects in Machined Ceramics by Application of Neural Networks to Laser Scatter Patterns (2008)

Laser scatter has shown promise as a method to characterize damage microstructural variations as well as a method to characterize surfaces in optical translucent ceramics. Because large volumes of data need to be handled (and sorted) quickly, automated pattern recognition methods using neural networks have been implemented to recognize differences in patterns. A He-Ne laser (γ=0.632μ) has been used to obtain scatter patterns from hot pressed Si3N4 with various microstructural variations. By use of a backpropagation neural network running on an IBM PC clone 486/33 machine, a correlation was established between subsurface microstructure and position in Si3N4 ball bearings. The data were confirmed by destructive analysis.
Contralateral Pleural Effusion Secondary toNonmetastatic Renal Cell Carcinoma (1990)

We report a case of contralateral pleural effusion secondary to nonmetastatic renal cell carcinoma that resolved and did not recur after radical nephrectomy. Such effusions are not a contraindication to definitive therapy of the primary renal tumor.
Alteration in the Sensitivity of GABA<sub>A</sub>Receptors to Allosteric Modulatory Drugs in Rat Hippocampus After Chronic Intermittent Ethanol Treatment (1998)

Chronic intermittent ethanol (CIE)-treated rats exhibited a kindling-like persistent increase in withdrawal hyperexcitability. The alteration of GABA(A) receptor (GABA(A)R) function in the hippocampus was suggested as a possible mechanism underlying the hyperexcitability observed in CIE rats, because (1) GABA(A)R agonist (muscimol)-evoked 36Cl- efflux was decreased; (2) paired-pulse inhibition in the CA1 area, predominantly due to GABA(A)R-mediated recurrent inhibition, was persistently decreased; and (3) GABA(A)R subunit expression was altered in the hippocampus from CIE rats. To further characterize the functional alteration of GABA(A)R after CIE treatment, their sensitivity to acute ethanol, a steroid anesthetic (alphaxalone), and a benzodiazepine inverse agonist (DMCM; methyl-6,7-dimethoxy-4-ethyl-beta-carboline-3-carboxylate) were studied using either synaptically evoked GABA(A)R responses or exogenously applied muscimol-evoked responses in hippocampal slices. Bath application of ethanol (60 mM) enhanced the area of GABA(A)R-mediated inhibitory postsynaptic potentials in the hippocampal CA1 region from control and CIE rats, and this potentiation was significantly (p = 0.027) greater in CIE rats (98%) than in control rats (53%). The positive modulatory effect of alphaxalone (1 microM) on GABA(A)R-inhibitory postsynaptic potentials was not significantly different between control and CIE rats (p = 0.375), whereas alphaxalone allosterically increased [3H]flunitrazepam binding in the CA1 area only in CIE rats (by 20 to 25%, p < 0.01), but not in controls. On the other hand, the negative modulatory effect of DMCM (1 microM) on muscimol-evoked responses was significantly larger in CIE rats (p = 0.002). These results suggest that the sensitization of GABA(A)R to acute ethanol and benzodiazepine inverse agonists, and possibly neurosteroids, may underlie ethanol dependence after multiple ethanol withdrawal episodes. These altered pharmacological properties are most consistent with changes in the subunit composition in the CA1 area of this rat model of alcohol dependence.
Taste responses of the facial and glossopharyngeal nerves to amino acids in the rainbow trout (2001)

No significant differences were noted between responses of rainbow trout Oncorhynchus mykiss facial and glossopharyngeal nerves to 15 amino acids. Nine of these amino acids tested at 10−2 M were stimulatory, whereas only two tested at 10−3 M were effective gustatory stimuli. For both nerve systems, ≤10−3 M L-proline was the most stimulatory amino acid, with an estimated threshold of 10−7 M; however, L-α-amino-β-guanidino-propionic acid (estimated threshold of 3×10−3 M), was the most potent compound at 10−2 M. These results indicate that the same amino acids activate taste buds innervated by facial and glossopharyngeal nerves, respectively, and suggest that the same amino acids can be important in chemosensory feeding behaviour in the rainbow trout.
Serum insulin-like growth factor-binding protein-3 (IGFBP-3) levels and IGFBP-3 protease activity in normal, abnormal, and multiple human pregnancy. (1995)

Proteolytic activity directed against insulin-like growth factor (IGF)-binding protein-3 (IGFBP-3) is found in human pregnancy serum. We have investigated changes in this protease activity in pregnancies in which the fetus is small for gestational age and in multiple pregnancies. Maternal serum was obtained from 18 singleton pregnancies at 27 weeks gestational age (GA), and matched fetal serum was collected by cordocentesis. Fetuses were appropriate for GA (AGA; n = 6), small for gestational age (SGA) with evidence of uteroplacental insufficiency (UPI; starved SGA; n = 6), or SGA without UPI (nonstarved SGA; n = 6). In a second study, serum was obtained from women with singleton (n = 10), twin (n = 10), and higher multiple pregnancies (n = 10) at 9 weeks GA. All women with more than three fetuses underwent embryo reduction to 2 fetuses before 15 weeks gestation, when a second serum sample was obtained. Circulating IGF-I and IGF-II were measured by RIA, and IGFBP-3 was measured by both RIA and immunoradiometric assay. IGFBP-3 protease activity was assessed by Western ligand blotting after incubation with a normal nonpregnancy sera pool, immunoblotting, and specific protease assay. In the growth study, circulating maternal IGF-I and IGFBP-3 levels were not different in the three groups, but fetal IGF-I and IGFBP-3 levels were significantly lower in the UPI fetuses (IGF-I, 6.9 +/- 0.5 micrograms/L; IGFBP-3, 547 +/- 70 micrograms/L) than in either the nonstarved SGA fetuses (IGF-I, 27.8 +/- 6.3; IGFBP-3, 769 +/- 41 micrograms/L; P < 0.01) or the AGA fetuses (IGF-I, 39.4 +/- 3.4; IGFBP-3, 872 +/- 91 micrograms/L; P < 0.01). Maternal serum IGFBP-3 protease activity, measured by protease using [125I]IGFBP-3 as substrate, was increased in pregnancies complicated by UPI compared with GA-matched pregnancies in which the fetus was AGA or nonstarved SGA. No significant fetal serum protease activity was demonstrated. In the multiple pregnancies, IGFBP-3 rose significantly from 9-15 weeks GA in singleton (P = 0.005), twin (P = 0.004), and multiple (P = 0.007) pregnancies, and levels were higher in mothers of multiple pregnancies than in those of twin (P < 0.05) or singleton (P < 0.01) pregnancies at both 9 and 15 weeks GA. IGF-I levels were not different in the three groups and did not significantly increase between 9-15 weeks GA.(ABSTRACT TRUNCATED AT 400 WORDS)
Comparative Genomics of <i>Brassica oleracea</i> and <i>Arabidopsis thaliana</i> Reveal Gene Loss, Fragmentation, and Dispersal after Polyploidy (2006)

We sequenced 2.2 Mb representing triplicated genome segments of Brassica oleracea, which are each paralogous with one another and homologous with a segmentally duplicated region of the Arabidopsis thaliana genome. Sequence annotation identified 177 conserved collinear genes in the B. oleracea genome segments. Analysis of synonymous base substitution rates indicated that the triplicated Brassica genome segments diverged from a common ancestor soon after divergence of the Arabidopsis and Brassica lineages. This conclusion was corroborated by phylogenetic analysis of protein families. Using A. thaliana as an outgroup, 35% of the genes inferred to be present when genome triplication occurred in the Brassica lineage have been lost, most likely via a deletion mechanism, in an interspersed pattern. Genes encoding proteins involved in signal transduction or transcription were not found to be significantly more extensively retained than those encoding proteins classified with other functions, but putative proteins predicted in the A. thaliana genome were underrepresented in B. oleracea. We identified one example of gene loss from the Arabidopsis lineage. We found evidence for the frequent insertion of gene fragments of nuclear genomic origin and identified four apparently intact genes in noncollinear positions in the B. oleracea and A. thaliana genomes.
Matrix converter solution for aircraft starting (2003)

The matrix converter is seen as potentially the ultimate topology for compact, high power density, high waveform quality, efficient four-quadrant AC-AC conversion. A matrix converter has been developed to meet a specific military application, with stringent requirements for output waveform quality, transient response and supply current harmonics. In order to meet the input and output waveform requirements resonant filters are used. These have driven the design, resulting in a relatively large equipment. The achievement of waveform quality and transient performance together poses a special problem for the control design. To optimise the power density, it is very important to start with a specification that does not needlessly over constrain the design. Output filter considerations illustrate the very large impact that specifications can have on static converter equipment design. It is very important to avoid over specification when considering static conversion replacements for MG type equipment. Bi-directional switches based on IGBT technology, capable of blocking voltage and conducting current in both directions, are now available in industry standard packages. The area of protection has been seen as the last remaining obstacle to the commercial exploitation of the matrix converter topology. The paper describes how control and protection of the matrix converter may be achieved using modern DSP/FPGA devices. The matrix converter is compared with a state-of-the-art PWM inverter using a DC link capacitor, designed to meet a less onerous specification. The matrix converter is best suited to applications where power density carries a premium. Its advantages will become clearer with the advent of high temperature silicon carbide devices. (18 pages)
Initial chemoimmunotherapy in inflammatory carcinoma of the breast (1982)

Fifteen patients with clinical primary inflammatory carcinoma of the breast were treated with initial chemoimmunotherapy between September 1974 and May 1977. The protocol was a combination of Adriamycin, vincristine, 5-fluorouracil, and methotrexate given by I.V. push, and melphalan per os. Thermographic cooling was taken as the criterion of operability. Initial chemotherapy was resumed after surgery up to a total of ten courses and followed by maintenance chemotherapy for a minimum of one year. Immunotherapy using I-BCG-F. Pasteur was routinely associated with the antimitotic agents. The median survival for our 15 patients has not been reached and exceeds 56 months. These results correspond to an obvious therapeutic benefit compared with recent attempts in which similar chemoimmunotherapy protocols were used; this benefit seems to be the consequence of the adaptation of the length of initial chemotherapy to the data given by plate-thermography.

Mouse lewis lung carcinoma and hepatoma ascites treatment by combination of liposome chemotherapy and non‐specific immunotherapy (1984)

Liposomes have been used as biological carriers of anti-tumor drugs, and their potential use has been tested in mouse Lewis lung carcinoma and hepatoma ascites tumor models. Ara-C3 given by the intraperitoneal i.p. route either at 35 mg/kg in a single dose or at 2.5 mg/kg/dose with 5 doses/day for 3 days had no effect on the average survival time of i.v. implanted LLC. However, the same single dose of Ara-C encapsulated in positively charged MLV significantly improved the average survival time of LLC-bearing mice. MTX was chosen as a test drug for the treatment of hepatoma ascites. Non-encapsulated MTX given at either 3 or 30 mg/kg by the i.p. route had little effect on the average survival of i.p.-implanted hepatoma ascites. However, MTX encapsulated in SUV at a 3 mg/kg dose by the i.p. route significantly improved the average survival time of tumor-bearing mice. A combination of chemotherapy and non-specific immunotherapy has also been tested with these 2 tumor models. Two non-specific microbial immune stimulators, Bacillus Calmette Guérin (BCG) and Corynebacterium parvum (CP) were tested by both the i.v. and i.p. routes. A combination of BCG therapy with non-encapsulated anti-tumor drugs was not effective for either of the tumor models. A combination of BCG therapy with liposome therapy appeared to improve the average survival time of LLC-bearing mice. In particular, BCG treatment by the i.p. route in combination with liposome therapy resulted in a 20% long-term survival rate among treated mice. However, BCG therapy by either route in combination with SUV encapsulated MTX therapy had no effect on the average survival time of hepatoma ascites-bearing mice. Immunostimulation with CP at a given dose appears to be superior to BCG therapy for both tumor models. In the treatment of LLC, injection of CP by either the i.v. or i.p. route appears to be equally effective in combination with liposome therapy. However, for the treatment of hepatoma ascites, CP was only effective by the i.p. route, in combination with liposome therapy.
Electronic structure and stability of complex hydrides Mg2 MH x (M = Fe, Co) (2013)

This paper reports on the results of theoretical investigations carried out for the hydrides Mg2FeH6 and Mg2CoH5 and the mixed hydride Mg2(FeH6)0.5(CoH5)0.5 in terms of the full-potential linearized augmented plane wave (FLAPW) method. It has been shown that the partial substitution of the Co atoms for the Fe atoms leads to a slight increase in the stability of the hydride, but, at the same time, makes it impossible to increase the stability of the alloy. The high stability of the hydrides under investigation has been explained by the strong bonding between atoms of the transition metal and hydrogen.
An evolutionary optimized vehicle tracker in collaboration with a detection system (2009)

In this work a learning algorithm for visual object tracking is presented. As object representation a fast computable set of Haar-like features is used and a weighted correlation is applied for the matching process. The object tracker utilizes the same set of features that is already calculated for object detection and thus it is possible to reuse features for detection and tracking. The feature's weight values are optimized for the tracking purpose by means of evolutionary strategies. Different tests of the object tracker on real-world sequences are presented using vehicles as example objects. Additionally, an object detection system and the integration of the object tracker into that system is described. Besides the system is based on a cascade of boosted classifiers, Haar and Triangle features, an adaptive sliding window and finally a Kalman filter.
Isolation and sequence of the gene for the large subunit of ribulose-1,5-bisphosphate carboxylase from the cyanobacterium <i>Anabaena</i> 7120 (1983)

Cloned DNA probes containing genes coding for the large subunit of ribulose-1,5-bisphosphate carboxylase (rbcA) of corn and of Chlamydomonas were used to identify, by heterologous hybridization, DNA fragments from Anabaena 7120 carrying the corresponding gene sequence. The same probes were used to isolate, from a recombinant lambda library, a 17-kilobase-pair EcoRI Anabaena DNA fragment containing the coding sequence for the rbcA gene. The entire coding sequence, as well as 210 base pairs of 5' flanking region and 210 base pairs of 3' flanking region, was determined. Comparison of the nucleotide and amino acid sequences with those of corn, spinach, Chlamydomonas, and Synechococcus rbcA genes revealed homology of 71-77% at the nucleotide level and 80-85% at the amino acid level. Conservation of sequence is lost immediately outside the coding region on either side. Codon usage in the Anabaena rbcA gene is not significantly different from that in the Anabaena genes for nitrogenase reductase and nitrogenase beta subunit.

THE FIELD OF AN ELECTRIC DIPOLE AND THE POLARIZABILITY OF A CONDUCTING OBJECT EMBEDDED IN THE INTERFACE BETWEEN DIELECTRIC MATERIALS (2009)

In this paper, a study is made of the electrostatic potential and fleld of an electric dipole located in the interface between two dielectric regions. When the dipole is oriented perpendicular to the interface, the detailed position of the charges of the dipole relative to the location of the interface has a signiflcant efiect on the value of the fleld produced away from the dipole, unlike the case of a dipole parallel to the interface. It is shown that it is the total dipole moment (due to both free and bound charges), rather than simply the impressed (free) dipole moment that is important in determining the fleld in this case. Based on these results, the question of deflning and determining the electric polarizability of a perfectly conducting object partially embedded in a dielectric interface is examined. The example of a conducting sphere embedded halfway in the interface is studied as a demonstration of our general formulation. The results of this paper are important for the proper modeling of arrays of scatterers embedded in an interface, such as frequency-selective surfaces (FSSs) and metafllms.

Methods of imparting information to patients in dental practice. (1984)

Changes are taking place in dentistry now that we know much more about the causes of caries, periodontal disease and most jaw malformations and that, through education and motivation, our patients can substantially protect themselves from these disorders. In our specialty in particular, it is true that 'prevention is better than cure'! This approach will be successful only if our patients are monitored on a regular recall basis. Attention is drawn to the existence of specific target groups. Successful results can only be achieved if individual efforts are backed by group and population prophylactic measures on the part of national or local authorities using the expertise of the dental profession. A preventively orientated practice must offer much more patient education than one which concentrates on the provision of curative services. Details of the approach to be followed should be thoroughly planned and the members of the dental team to be responsible for the tasks concerned should be identified. Appropriate equipment and working facilities are essential for the effective conduct of preventive measures. It must be emphasized that these measures in dental practice involve high costs. In attending to our patients, we should not forget that not only practical intervention but also the provision of advice is a vitally important health service.
A Heteromeric Plastidic Pyruvate Kinase Complex Involved in Seed Oil Biosynthesis in<i>Arabidopsis</i> (2007)

Glycolysis is a ubiquitous pathway thought to be essential for the production of oil in developing seeds of Arabidopsis thaliana and oil crops. Compartmentation of primary metabolism in developing embryos poses a significant challenge for testing this hypothesis and for the engineering of seed biomass production. It also raises the question whether there is a preferred route of carbon from imported photosynthate to seed oil in the embryo. Plastidic pyruvate kinase catalyzes a highly regulated, ATP-producing reaction of glycolysis. The Arabidopsis genome encodes 14 putative isoforms of pyruvate kinases. Three genes encode subunits alpha, beta(1), and beta(2) of plastidic pyruvate kinase. The plastid enzyme prevalent in developing seeds likely has a subunit composition of 4alpha4beta(1), is most active at pH 8.0, and is inhibited by Glu. Disruption of the gene encoding the beta(1) subunit causes a reduction in plastidic pyruvate kinase activity and 60% reduction in seed oil content. The seed oil phenotype is fully restored by expression of the beta(1) subunit-encoding cDNA and partially by the beta(2) subunit-encoding cDNA. Therefore, the identified pyruvate kinase catalyzes a crucial step in the conversion of photosynthate into oil, suggesting a preferred plastid route from its substrate phosphoenolpyruvate to fatty acids.
