Experimental infection of the New World owl monkey (Aotus trivirgatus) with hepatitis A virus (1983)

Epidemiological studies have demonstrated the susceptibility of the owl monkey (Aotus trivirgatus) to hepatitis A virus, but have not shown an association between infection and histopathological or chemical evidence of liver disease. Therefore, 12 seronegative, colony-bred monkeys were inoculated intravenously with a fecal suspension containing either PA33 strain hepatitis A virus (a strain recovered from a naturally infected Aotus sp.) or HM-175 virus (recovered from a human). Viral antigen was detected by radioimmunoassay in the feces of six monkeys 6 to 17 days after inoculation with PA33 virus, and by 9 to 21 days serum aminotransferase activities were significantly elevated in each. Antibody to the virus developed in each monkey by 28 days after inoculation. Similar findings were noted in five of six monkeys inoculated with HM-175 virus, although the incubation period preceding aminotransferase elevations was somewhat longer (25 to 39 days). Liver biopsies obtained from the 11 infected monkeys demonstrated mild to moderate portal inflammation, as well as random areas of focal necrosis and inflammation extending outward from the portal region. These data confirm the susceptibility of Aotus sp. to hepatitis A virus and indicate that the infection of this primate provides a useful animal model of human hepatitis A.

Submitochondrial localization and function of enzymes of glutamine metabolism in avian liver. (1977)

Glutamine synthetase (EC 6.3.1.2) was localized within the matrix compartment of avian liver mitochondria. The submitochondrial localization of this enzyme was determined by the digitonin-Lubrol method of Schnaitman and Greenawalt (35). The matrix fraction contained over 74% of the glutamine synthetase activity and the major proportion of the matirx marker enzymes, malate dehydrogenase (71%), NADP-dependent isocitrate dehydrogenase (83%), and glutamate dehydrogenase (57%). The highest specific activities of these enzymes were also found in the matrix compartment. Oxidation of glutamine by avian liver mitochondria was substantially less than that of glutamate. Bromofuroate, an inhibitor of glutamate dehydrogenase, blocked oxidation of glutamate and of glutamine whereas aminoxyacetate, a transaminase inhibitor, had little or no effect with either substrate. These results indicate that glutamine metabolism is probably initiated by the conversion of glutamine to glutamate rather than to an alpha-keto acid. The localization of a glutaminase activity within avian liver mitochondria plus the absence of an active mitochondrial glutamine transaminase is consistent with the differential effects of the transaminase and glutamate dehydrogenase inhibitors. The high glutamine synthetase activity (40:1) suggests that mitochondrial catabolism of glutamine is minimal, freeing most of the glutamine synthesized for purine (uric acid) biosynthesis.
Multi-Cantilever-Driven Rotational Micrograting for MOEMS Spectrometer (2007)

For the purpose of detecting biological fluorescence, a rotational actuator with integrated diffraction grating is designed as the central part of a MOEMS spectrometer. In order to produce scanning with a lithographically defined micrograting, angular displacement is produced with multiple balanced beams placed in opposition around a semi-floating pivot point. Piezoelectrically driven, the beams rotate a suspended micro grating linearly with voltage, directly tuning the angularly spread spectral outputs. The design advantages, optimizations and fabrication are discussed. The fabricated actuator is used in a fluorescence scanning of paper cellulose fibers and Rhodamine B dye, and shown to be effective in rotating a diffraction grating for fluorescence spectroscopy.

PCC-PCE Communication Requirements for Point to Multipoint Multiprotocol Label Switching Traffic Engineering (MPLS-TE) (2008)

The Computation Element (PCE) provides path computation functions
in support of traffic engineering in Multi-Protocol Label Switching
(MPLS) and Generalized MPLS (GMPLS) networks. Extensions to the MPLS
and GMPLS signaling and routing protocols have been made in support of
point-to-multipoint (P2MP) Traffic Engineered (TE) Label Switched
Paths (LSPs). The use of PCE in MPLS networks is already established,
and since P2MP TE LSP routes are sometimes complex to compute, it is
likely that PCE will be used for P2MP LSPs. Generic requirements for
a communication protocol between Computation Clients (PCCs) and
PCEs are presented in Path Computation Element (PCE) Communication
Protocol Generic Requirements. This document complements the generic
requirements and presents a detailed set of PCC-PCE communication
protocol requirements for point-to-multipoint MPLS/GMPLS traffic
engineering.
Size and persistence length of molecular bottle-brushes by Monte Carlo simulations (2004)

Single-chain simulations of densely branched comb polymers, or "molecular bottle-brushes" with side-chains attached to every (or every second) backbone monomer, were carried out by off-lattice Monte Carlo technique. A coarse-grained model, described by hard spheres connected by harmonic springs, was employed. Backbone lengths of up to 100 units were considered, and compared with the corresponding linear chains. The backbone molecular size was investigated as a function of its length at fixed arm size, and as a function of the arm size at fixed backbone length. The apparent swelling exponents obtained by a power-law fit were found to be larger than those for the corresponding linear polymers, indicative of stiffening of the comb backbone. The probability distribution function for the backbone end-to-end distance was also investigated for different backbone lengths and arm sizes. Analysis of this function yielded the critical exponents, which revealed an increase in the swelling exponent consistent with values found from the molecular size. The apparent persistence length of the backbone was also determined, and was found to increase with increasing branching density. Finally, the static structure factors of the whole bottle-brushes and of their backbones are discussed, which provides another consistent estimate of the swelling exponents.
SPEEDES - A multiple-synchronization environment for parallel discrete-event simulation (1992)

Synchronous Parallel Environment for Emulation and Discrete-Event Simulation (SPEEDES) is a unified parallel simulation environment. It supports multiple-synchronization protocols without requiring users to recompile their code. When a SPEEDES simulation runs on one node, all the extra parallel overhead is removed automatically at run time. When the same executable runs in parallel, the user preselects the synchronization algorithm from a list of options. SPEEDES currently runs on UNIX networks and on the California Institute of Technology/Jet Propulsion Laboratory Mark III Hypercube. SPEEDES also supports interactive simulations. Featured in the SPEEDES environment is a new parallel synchronization approach called Breathing Time Buckets. This algorithm uses some of the conservative techniques found in Time Bucket synchronization, along with the optimism that characterizes the Time Warp approach. A mathematical model derived from first principles predicts the performance of Breathing Time Buckets. Along with the Breathing Time Buckets algorithm, this paper discusses the rules for processing events in SPEEDES, describes the implementation of various other synchronization protocols supported by SPEEDES, describes some new ones for the future, discusses interactive simulations, and then gives some performance results.
Fundamental limits to optical response in absorptive systems (2016)

At visible and infrared frequencies, metals show tantalizing promise for strong subwavelength resonances, but material loss typically dampens the response. We derive fundamental limits to the optical response of absorptive systems, bounding the largest enhancements possible given intrinsic material losses. Through basic conservation-of-energy principles, we derive geometry-independent limits to per-volume absorption and scattering rates, and to local-density-of-states enhancements that represent the power radiated or expended by a dipole near a material body. We provide examples of structures that approach our absorption and scattering limits at any frequency; by contrast, we find that common "antenna" structures fall far short of our radiative LDOS bounds, suggesting the possibility for significant further improvement. Underlying the limits is a simple metric, |χ|2/Im χ for a material with susceptibility χ, that enables broad technological evaluation of lossy materials across optical frequencies.
An assisted photography method for street scenes (2011)

We present an interactive, computational approach for assisting users with visual impairments during photographic documentation of transit problems. Our technique can be described as a method to improve picture composition, while retaining visual information that is expected to be most relevant. Our system considers the position of the estimated region of interest (ROI) of a photo, and camera orientation. Saliency maps and Gestalt theory are used for guiding the user towards a more balanced picture. Our current implementation for mobile phones uses optic flow to update the internal knowledge of the position of the ROI and tilt sensor readings to correct non horizontal or vertical camera orientations. Using ground truth labels, we confirmed our method proposes valid strategies for improving image composition. Future work includes an optimized implementation and user studies.
The effects of concentrated barley β-glucan on blood lipids in a population of hypercholesterolaemic men and women (2007)

Barley, like oats, is a rich source of the soluble fibre beta-glucan, which has been shown to significantly lower LDL-cholesterol (LDL-C). However, barley foods have been less widely studied. Therefore, we evaluated the LDL-C-lowering effect of a concentrated barley beta-glucan (BBG) extract as a vehicle to deliver this potential health benefit of barley. In a 10-week blinded controlled study, subjects were randomized to one of four treatment groups or control. Treatment groups included either high molecular weight (HMW) or low molecular weight (LMW) BBG at both 3 and 5 g doses. Treatment was delivered twice per day with meals in the form of two functional food products: a ready-to-eat cereal and a reduced-calorie fruit juice beverage. Levels of total cholesterol, LDL-C, HDL-cholesterol (HDL-C), and TAG were determined at baseline and after 6 weeks of treatment. The study group comprised 155 subjects. All treatments were well tolerated and after 6 weeks of treatment the mean LDL-C levels fell by 15 % in the 5 g HMW group, 13 % in the 5 g LMW group and 9 % in both the 3 g/d groups, versus baseline. Similar results were observed for total cholesterol. HDL-C levels were unchanged by treatment. Concentrated BBG significantly improves LDL-C and total cholesterol among moderately dyslipidaemic subjects. Food products containing concentrated BBG should be considered an effective option for improving blood lipids.

Stacked CMOS SRAM cell (1983)

A static random access memory (SRAM) cell with cross-coupled stacked CMOS inverters is demonstrated for the first time. In this approach, CMOS inverters are fabricated with a laser recrystallized p-channel device stacked on top of and sharing the gate with a bulk n-channel device using a modified two-polysilicon n-MOS process. The memory cell has been exercised through the write and read cycles with external signal generators while the output is buffered by an on-chip, stacked-CMOS-inverter-based amplifier.
Cyclin-dependent kinase inhibitor expression in pulmonary Clara cells transformed with SV40 large T antigen in transgenic mice. (1997)

Expression of cell cycle regulatory genes in mouse lung was investigated in transgenic models for Clara cell transformation. Clara cells were transformed by generating transgenic mice in which the SV40 large T antigen was expressed under the control of the mouse Clara cell M(r) 10,000 protein promoter. The resulting lung tumors express the large T antigen in normal Clara cells and in tumors, and these tumors express reduced levels of CC10 mRNA. The expression of cell cycle regulatory protein, p53, and the cyclin-dependent kinase inhibitors was analyzed by Northern blot analysis and in situ hybridization throughout the progression of Clara cell transformation in the lung. Increases in specific cyclin-dependent kinase inhibitor steady-state mRNA levels were detected in p15, p18, p27, and p57 during tumor progression. The expression of p15, p57, and p21 mRNAs were verified by in situ hybridization. Using this approach, regulatory genes have been identified that may be involved in the regulation of Clara cell differentiation.
An intelligent interface for diagram navigation (2002)

Display and navigation of diagrams play an important role in visual information processing, especially for visualising large scale information systems. Based on our analysis of various diagram display techniques, we have chosen a suitable display technique for the purpose of diagram navigation. We have aimed at automatic navigation of large diagrams. By reasoning and making inferences, based on the user's clue set provided visually, a diagram is traversed following some navigation path. By combining diagram display and automatic navigation, a prototype system has been developed.
Maximizing Scroll Compressor Displacement Using Generalized Wrap Geometry (1994)

In designing ever smaller compressors, a problem with scrolls is that conventional wraps require an operating space which is non-circular and off-center from the axis of the compressor assembly.Many scroll designs have unused volume around the outside of the wraps.In this paper, a method is adopted using general conjugacy relations to define a scroll geometry which fills a circular periphery and makes better use of available space for displacement.This provides as much as 18 percent or more increased capacity with no increase in size.
Molecular detection of cancer cells in the peripheral blood of patients with breast cancer: comparison of CK-19, CEA and maspin as detection markers. (2003)

RT-PCR positivity for CK-19 mRNA is the most sensitive detection marker for occult tumor cells in operable and metastatic breast cancer, although nested RT-PCR for maspin mRNA appears to be more specific.
Modelling the distribution and interaction of introduced rodents on New Zealand offshore islands (2004)

ABSTRACT Aim To establish the factors that correlate with the distribution of the four most commonly introduced rodent species on New Zealand offshore islands — ship rat ( Rattus rattus ), Norway rat ( R. norvegicus ), Pacific rat or kiore ( R. exulans ) and house mouse ( Mus musculus ) — and examine if these distributions are interactive at the archipelago scale. Location The 297 offshore islands of the New Zealand archipelago (latitude: 34° S to 47° S; longitude: 166° E to 179° E). Methods Data on the distribution of all four introduced rodent species and the characteristics of New Zealand offshore islands were collated from published surveys and maps. The distribution of individual rodent species was regressed on island characteristics using a logistic generalized linear model. Interactions were examined by including the distributions of other rodent species as predictors in models. Results All four rodent species appear to be limited by a variety of factors, which differ between species in both number and type. The distribution of ship rats is limited by the most factors, reflecting the extent of its distribution across the archipelago. The distribution of mice is the least explicative. Only the three rat species interacted in their distribution. The distribution of kiore on offshore islands is significantly negatively related to that of ship rats and to a lesser extent Norway rats. The distribution of mice did not appear affected in any way by the number of other rodent species on an island. Main conclusions Differences in competitive ability and dispersal allow all four species to inhabit the New Zealand archipelago. Kiore distribution appears to be most limited by ship rat (and to a lesser extent Norway rat) distribution. The distribution of kiore was not found to interact with the distribution of mice on offshore islands, as has been suggested by others. The distribution of mice on offshore islands was difficult to model, which highlights the difficulties in managing this species. Overall the results offer valuable insights for management methods to assist preventing the invasion of offshore islands.
A texture-based method for classifying cracked concrete surfaces from digital images using neural networks (2011)

Using a dSLR camera with macro LED light, 11 samples containing light and moderately cracked concrete surfaces were imaged with perpendicular and angled illumination. Textural features from gray level co-occurrence matrix statistics were derived, from which 3-6 salient features were selected. Cross validation accuracies were as high as 94% using neural network classifiers, indicating the feasibility of rapid, automatic concrete cracking assessment using COTS digital imaging.
Ultrasound-guided cannulation versus the landmark-guided technique for acute haemodialysis access (1997)

The use of ultrasound guidance is associated with fewer complications and is more likely to lead to cannulation of the vein at the first attempt in haemodialysis patients.
Lymphocyte Subpopulations and Cytokine Production in Paracoccidioidomycosis Patients (1991)

Despite the postulated role of the immune system in the control of the infection by Paracoccidioides brasiliensis, only a few studies have addressed this point in patients. The determination of total lymphocytes and their subpopulations in 6 untreated patients with the chronic form of paracoccidiodomycosis showed that half of them were lymphopenic, because of low number of CD4+ T-lymphocytes. All patients had low CD4/CD8 ratios. On the contrary, B-lymphocytes were normal in all patients. An additional patient, studied on treatment with ketoconazole, had normal lymphocyte counts in all subpopulations, as did one of the patients previously studied at diagnosis when he received specific antimycotic treatment. The production of interferon and tumor necrosis factor, determined by bioassay in supernatants of mononuclear blood cells of the patients, induced by interleukin 2 in vitro was significantly lower than that of normal subjects. These results show that patients with paracoccidioidomycosis have a defect in blood lymphocyte subsets as well as in the ability to produce regulatory cytokines.
Bone Formation from Porcine Dental Germ Stem Cells on Surface Modified Polybutylene Succinate Scaffolds (2016)

Designing and providing a scaffold are very important for the cells in tissue engineering. Polybutylene succinate (PBS) has high potential as a scaffold for bone regeneration due to its capacity in cell proliferation and differentiation. Also, stem cells from 3rd molar tooth germs were favoured in this study due to their developmentally and replicatively immature nature. In this study, porcine dental germ stem cells (pDGSCs) seeded PBS scaffolds were used to investigate the effects of surface modification with fibronectin or laminin on these scaffolds to improve cell attachment, proliferation, and osteogenic differentiation for tissue engineering applications. The osteogenic potentials of pDGSCs on these modified and unmodified foams were examined to heal bone defects and the effects of fibronectin or laminin modified PBS scaffolds on pDGSC differentiation into bone were compared for the first time. For this study, MTS assay was used to assess the cytotoxic effects of modified and unmodified surfaces. For the characterization of pDGSCs, flow cytometry analysis was carried out. Besides, alkaline phosphatase (ALP) assay, von Kossa staining, real-time PCR, CM-Dil, and immunostaining were applied to analyze osteogenic potentials of pDGSCs. The results of these studies demonstrated that pDGSCs were differentiated into osteogenic cells on fibronectin modified PBS foams better than those on unmodified and laminin modified PBS foams.
[Hypotheses on the establishment of a genetic code and transfer of information from proteinoids to nucleic acids]. (1984)

An hypothesis is proposed in which the specificity of interaction between an aminoacid and a nucleotide sequence of a tRNA would be enhanced by a ternary association with a specific proteinoid. These strict relations would have led to the present genetic code that we know. It is also proposed that the origin of the enzymatic activity of the primitive proteinoids would have arisen from the presence of different substrates during polymerisation, which would have favored specific sequences of aminoacids by forming more stable complexes with them, corresponding to the lowest free enthalpy. The information included in the aminoacid sequences of the proteinoids would have been transferred to messenger type RNA, according to a mechanism reverse of that for the present process for protein synthesis, and then to DNA.
