Radioimmunoassay of O<sup>6</sup>-methyldeoxyguanosine in DNA of cells alkylated <i>in vitro</i> and <i>in vivo</i> (1983)

Mouse monoclonal and rabbit polyclonal antibodies have been prepared against O6-methylguanosine complexed with bovine serum albumin. In radioimmunoassay 50% inhibition of binding of [3H]O6-methyldeoxyguanosine (O6-MedG) was obtained with 0.3 pmol or 0.16 pmol unlabelled O6-MedG using monoclonal or polyclonal antibodies having affinity constants of 3.0 X 10(9) and 5.9 X 10(9) I mol-1 respectively. Cross-reactivity with normal nucleosides and other adducts was determined. Sensitivity and reproducibility were improved by chromatographic separation using an Aminex A6 column eluted with 10 mM NH4HCO3 buffer which allowed quantitation of one molecule O6-MedG per 10(7) molecules dG in 2 mg calf thymine DNA. Values for O6-MedG from 14 samples of rat liver and kidney DNA analysed by the method described and by radiochromatography on Sephadex G10 were almost identical (correlation coefficient, 0.98). A modified procedure for the purification of 5-25 micrograms DNA from 1-5 X 10(6) fibroblasts applied to polycarbonate filters was used in providing further validation of the RIA system by measuring the persistence of O6-MedG in cell lines of known repair capacity.

Thermal Limitations in Superconducting RF Cavities: Improved Heat Transfer at Niobium-Helium Interface (2006)

The accelerating gradients in superconducting RF cavities can be limited by excessive temperature rise on the inner surface. In some circumstances, such as high RF frequency or anomalous losses, improved heat transfer at the niobium‐helium interface can increase the achievable gradient. Different surface morphology techniques have been applied to reduce the limitation at the thermal interface. These techniques include varying surface roughness and forming cooling channels (embedded fins) in the surface. Heat transfer measurements on several niobium samples of different surface states, but same bulk purity at both Helium I and II (super‐fluid) temperature regimes are planned. Initial measurements to validate the experimental setup on one sample are presented. Comparison of the test measurements is made with the existing literature data. The surface characterization uses a high‐resolution 3D optical nano‐scope. Finally, the influence of these interface surface techniques on the performance of the cavities will be discussed.
Measurement of workload for voice user interface systems (2005)

Measurement of workload using voice user interface systems is helpful for improving usability. We propose an evaluation method which performs the main task of listening and answering via voice and the subtask of pressing the keyboard responding to signs on the visual display simultaneously. Using this dual-task method, we can find the parts of the voice interface systems where the user experienced problems. These are the parts the developer must improve. Our experiments showed that the proposed method reflected the difference of task difficulties significantly. © 2005 Wiley Periodicals, Inc.

A cross-layer scheme to improve TCP performance in UMTS with packet scheduling (2006)

In the third-generation (and beyond) wireless communication systems, one important MAC issue is the packet scheduling, common criterion for packet scheduler design just include maximization of throughput and QoS provisioning of link- layer. No consideration is taken on the deterioration of TCP performance caused by the packet scheduling. In this paper, the impact of packet scheduling upon TCP is analyzed and a cross-layer scheme AAFC(active ACK forwarding control) is proposed to relieve the deterioration of TCP performance. The basic idea of this approach, which overcomes the interference between the MAC and TCP, is to control the forwarding step of reverse ACK segment at base station in order to avoid the pseudo TCP time out. The simulation results show that the proposed approach can increase TCP throughput greatly.
Microwave radiation can alter protein conformation without bulk heating (2003)

Exposure to microwave radiation enhances the aggregation of bovine serum albumin in vitro in a time- and temperature-dependent manner. Microwave radiation also promotes amyloid fibril formation by bovine insulin at 60 degrees C. These alterations in protein conformation are not accompanied by measurable temperature changes, consistent with estimates from field modelling of the specific absorbed radiation (15-20 mW kg(-1)). Limited denaturation of cellular proteins could explain our previous observation that modest heat-shock responses are induced by microwave exposure in Caenorhabditis elegans. We also show that heat-shock responses both to heat and microwaves are suppressed after RNA interference ablating heat-shock factor function.

Leaf Regulation of the Nitrogen Concentration in the Grain of Wheat Plants (1993)

The regulation of the final grain N concentration in wheat (Triticum aestivum) plants was studied through the alteration of the source/sink ratio. Plants were grown in a greenhouse in pots with soil, and fertilized with a supraoptimal N supply. The plants were divided into six groups. In one treatment, plants remained untouched as a control (Treatment 1). In another group, all the ears except that of the main tiller were removed at flowering (Treatment 2). All other plants were de-tillered after the emergence of the third leaf, leaving only one tiller per plant. At flowering, one plant set was left untouched (Treatment 3). In a second group, all the leaves were excised (Treatment 4). In another group half the spikelets of the ear were excised (Treatment 5) and in the last group three-quarters of the spikelets were excised (Treatment 6). Ear excision produced an increase in individual grain weight and the grain N concentration above the normal N concentration observed in this cultivar. The final N concentration was correlated with the concentration of free amino acids in the flag leaf 34 d after flowering. It is concluded that in intact plants grain protein synthesis is substrate-limited by the amino acid export pool in the leaves, and grain excision increases the availability of amino acids to be transported to the remaining grains.
3H and 125I radioimmunoassays of haloperidol compared with fluoroimmunoassay involving antibody coupled to magnetizable solid phase. (1981)

Radioimmunoassays for haloperidol are described, involving use of tritium- or 125I-labeled drug or tritium-labeled spiroperidol, and a rabbit antiserum to a drug/bovine serum albumin conjugate. The 125I-labeled drug was prepared by the Chloramine T iodination technique. A fluoroimmunoassay for haloperidol is also described in which the antiserum is coupled to magnetizable solid-phase medium, and fluorescein-labeled haloperidol is used. The assays have acceptable accuracy, precision, and reproducibility, and are specific for haloperidol and similar butyrophenones, with no significant interference from known metabolites and other drugs. Only the radioimmunoassays have sufficient sensitivity to cover the whole range of haloperidol concentrations in serum. The fluoroimmunoassay can be used to monitor high concentrations of haloperidol in 150-microL samples or the complete concentration range of 1-mL serum samples that are extracted and concentrated before assay.
Effect of Powder Compaction in Plastic Laser Sintering Fabrication (2009)

Powder compaction is introduced into plastic laser sintering fabrication. Compaction was carried out by using a roller of which rotation speed is independently controlled of its traversing speed. This additional process improved packing density of powder bed by a factor of 20% and reduced residual porosity of obtained parts by a factor of 30%. As an advantage, powder compaction can improve mechanical strength of parts of semi-crystalline powder, but increases excessive sinter to reduce fabrication accuracy especially in fabrication of amorphous plastic. This paper presents characteristics of the powder compaction process itself and its effects on performance of obtained parts.

Characterization of tissue-specific enhancer elements in the second intron of the human apolipoprotein B gene. (1991)

We report the identification and characterization of tissue-specific transcriptional enhancer elements that influence the expression of the human apolipoprotein B gene. A 704-base pair PstI fragment comprising sequences from the first and second introns of the human apolipoprotein B gene (positions +360 to +1064) possesses tissue-specific transcriptional enhancer elements when assayed in transient transfection experiments using either the apolipoprotein B or thymidine kinase promoter. The majority of the enhancer activity, which was observed in transcriptionally active HepG2 and CaCo-2 cells, but not in transcriptionally inactive Chinese hamster ovary or HeLa cells, was subsequently localized to a 443-base pair SmaI-PvuII fragment (positions +621 to +1064) within the second intron of the apolipoprotein B gene. Gel retention experiments demonstrated that sequence motifs within this region interact with a number of nuclear proteins from HepG2, CaCo-2, and HeLa cells. The actual sequence elements that bound to nuclear proteins from HepG2 cells were identified by DNase I footprinting. Deletion experiments were performed to distinguish those protein-binding regions involved in the enhancer effect. Our data demonstrate that sequences between positions +806 and +940 are essential for this enhancer activity. This segment contains one large 97-base pair footprint, whose sequence has been conserved between the human and mouse genes. Binding sites for the liver-specific transcription factors HNF-1 and HNF-3 are present within this footprint.
Liquid state machine based pattern recognition on FPGA with firing-activity dependent power gating and approximate computing (2016)

This paper presents an FPGA architecture and implementation of the Liquid State Machine, a spiking neural network model, for real world pattern recognition problems. The proposed architecture consists of a parallel digital reservoir with fixed synapses, and a readout stage that is tuned by a biologically plausible supervised learning rule. When evaluated using the TI46 speech corpus, a widely adopted speech recognition benchmark, the presented FPGA neuromorphic processors demonstrate highly competitive recognition performance and provide a runtime speedup of 88X over the 2.3 GHz AMD OpteronTM Processor. A number of critical design issues such as interconnection of liquid neurons, storage of synaptic weights and design of arithmetic blocks are addressed in this work. More importantly, it is shown that the unique computational structure and inherent resilience of the liquid state machine can be leveraged for highly efficient FPGA implementation. For t Iiis, it is demonstrated that the proposed firing-activity based power gating and approximate arithmetic computing with runtime adjustable precision can lead to up to 30.2% reduction in power and energy dissipation without greatly impacting speech recognition performance.
A Computationally Efficient Method for Nonparametric Modeling of Neural Spiking Activity with Point Processes (2010)

Point-process models have been shown to be useful in characterizing neural spiking activity as a function of extrinsic and intrinsic factors. Most point-process models of neural activity are parametric, as they are often efficiently computable. However, if the actual point process does not lie in the assumed parametric class of functions, misleading inferences can arise. Nonparametric methods are attractive due to fewer assumptions, but computation in general grows with the size of the data. We propose a computationally efficient method for nonparametric maximum likelihood estimation when the conditional intensity function, which characterizes the point process in its entirety, is assumed to be a Lipschitz continuous function but otherwise arbitrary. We show that by exploiting much structure, the problem becomes efficiently solvable. We next demonstrate a model selection procedure to estimate the Lipshitz parameter from data, akin to the minimum description length principle and demonstrate consistency of our estimator under appropriate assumptions. Finally, we illustrate the effectiveness of our method with simulated neural spiking data, goldfish retinal ganglion neural data, and activity recorded in CA1 hippocampal neurons from an awake behaving rat. For the simulated data set, our method uncovers a more compact representation of the conditional intensity function when it exists. For the goldfish and rat neural data sets, we show that our nonparametric method gives a superior absolute goodness-of-fit measure used for point processes than the most common parametric and splines-based approaches.
South Africa : doing business the hard way : economy (2013)

The ease with which one can start and operate a business is an indicator which provides insight into how readily citizens - and non-citizens, for that matter - can engage in productive, commercial activities. It should, therefore, be of some concern that South Africa is going backwards on at least one key monitor which measures ease of doing business. According to the World Bank's 'Doing Business' report, the country is ranked 41st out of 189 countries, down from a 2012 ranking of 35th. However, while this is worrying, all is not lost, as research from EY (formerly Ernst & Young) shows that South Africa remains a key destination for investment by foreign companies.
Comparative Effects of<i>Stevia rebaudiana</i>Leaves and Stevioside on Glycaemia and Hepatic Gluconeogenesis (2006)

The purpose of the present study was to compare the effect of the oral treatment (gavage) with Stevia rebaudiana (Bert.) Bertoni (SRB) and stevioside (STV) on glycaemia and gluconeogenesis of 15-h fasted rats. For this purpose, the rats received SRB (20 mg/kg x day), STV (5.5 mg/kg x day) or an equal volume of water (controls) during 15 days. To measure hepatic gluconeogenesis, liver perfusion and isolated hepatocytes were used. Glycaemia and gluconeogenesis from L-alanine (5 mM), L-glutamine (5 mM) and L-lactate (2 mM) were decreased (P < 0.05) after pre-treatment with SRB. However, the treatment with STV did not influence glycaemia and gluconeogenesis. Moreover, to get further information about the mechanism by which SRB leaves inhibit gluconeogenesis their potential role as a PPARgamma agonist was investigated. The data showed absence of activation of PPARgamma receptors. In summary, our results showed that the reduction of glycaemia promoted by the treatment with SRB leaves was mediated, at least in part, by an inhibition of hepatic gluconeogenesis. However, this effect did not involve stevioside and the activation of PPARgamma receptors.

Fabrication of optical beamwidth transformers for guided waves on InP using wedge-shaped taper structures (1991)

A waveguide device is proposed for spot-size transformation of an optical beam from the 1 μm range to about 8 μm using a wedge-shaped taper. The structure can be entirely integrated on an InP-based optoelectronically integrated circuit. It is shown by numerical simulation that the width of the thin end of the wedge has a major influence on the transformation loss of such a device. By using direct writing e-beam lithography and reactive ion etching as well as subsequent InP regrowth, we were able to produce the required structures. The beamwidth transformation capability is confirmed by optical measurements.
Organic Peroxyl Radical Photolysis in the Near-Infrared:  Effects on Tropospheric Chemistry (1999)

We investigate the effects of near-infrared photolysis of organic peroxyl radicals (RO2) on tropospheric chemistry. We propose that the excitation of an RO2 to its lowest excited electronic state with near-infrared (near-IR) light is followed by intramolecular reactions that produce hydroxyl (OH) or hydroperoxyl (HO2) radicals. Spectra to this low-lying state have recently been obtained, but absorption cross sections for this electronic transition and yields of the resulting photoproducts have not been directly measured. We suggest a limiting range of cross sections from estimates for the same transition in HO2 and by comparison to other allowed electronic transitions. On the basis of a thermochemical assessment, we propose that OH and an aldehyde are the principal photoproducts of near-IR photolysis of RO2. These photolysis reactions are included in a model of the troposphere with a standard photochemical mechanism and conditions appropriate to remote, rural, and urban locations. Inclusion of RO2 photolysis has a small effect on any of the major tropospheric chemical constituents if lower limit estimates of the absorption cross sections are used. Midrange or upper limit cross section estimates result in significant departures from the currently accepted photochemical scheme. These studies provide a clear need for further measurements of RO2 absorption cross sections and photoproduct yields, which are the principal uncertainties.
EFFECTS OF CAROLINA RINSE AND ADENOSINE RINSE ON MICROVASCULAR PERFUSION AND INTRAHEPATIC LEUKOCYTE-ENDOTHELIUM INTERACTION AFTER LIVER TRANSPLANTATION IN THE RAT (1993)

Flushing hepatic grafts immediately before revascularization with a specially designed rinse solution such as "Carolina rinse" has been reported to improve survival after liver transplantation in the rat. This study investigated the influence of Carolina rinse and adenosine rinse on early graft function, microcirculation, and leukocyte (WBC)-endothelial cell interaction of arterialized syngeneic orthotopic liver transplants in Lewis rats. Livers were preserved for 24 hr in University of Wisconsin solution and flushed immediately before reperfusion with either Ringer's lactate (group A: n = 7), Ringer's lactate + 0.2 mmol/liter adenosine (group B: n = 6), or Carolina rinse (group C: n = 7). Microvascular perfusion and WBC accumulation were assessed by intravital fluorescence microscopy. In group C, acinar perfusion was significantly improved, accompanied by a lower percentage of nonperfused sinusoids 1 hr after reperfusion (mean +/- SEM: 26 +/- 2% [group A], 21 +/- 2% [B], 11 +/- 1% [C], P < 0.01 for C vs. A or B). In addition, Carolina rinse and, to a lesser extent, adenosine rinse reduced the number of WBC sticking in sinusoids and postsinusoidal venules. Better graft function in group C was indicated by increased bile flow during the observation period of 90 min after reperfusion (0.5 +/- 0.3 ml/100 g liver [group A], 1.5 +/- 0.7 [B], 3.7 +/- 0.6 [C], P < 0.01 for C vs. A or B). We conclude that Carolina rinse is able to improve early excretory hepatocellular function, microvascular perfusion, and intrahepatic WBC accumulation after prolonged cold ischemia and reperfusion, but adenosine is unlikely to be the key component of this rinse solution.
